Agricultural engineering machinery mainly refers to small excavators, small loaders, and small cranes. These products are mainly oriented to the rural market, and the customer groups are concentrated in rural areas. The product configuration is low, the sales price is low, the comprehensive utilization rate is high, and the return is relatively abundant. Because of its wide range of uses, since 2000, as a rising star of agricultural construction machinery has developed rapidly, from 2000 to 2008, the average annual growth rate has always maintained a double-digit growth rate.
In addition, the country is gradually advancing new rural construction measures in the nationwide construction of urban and rural roads, rural drinking water safety projects, urban and rural integration and other construction projects, due to agricultural construction machinery is convenient, quick and flexible, can be in space It is characterized by its narrowness and use in areas with low requirements on road conditions, and has strong practicability and strong market demand.
It is understood that nearly 10 provinces in the country have included agricultural construction machinery in the list of agricultural machinery purchase subsidies. This is undoubtedly a long-term positive news for agricultural construction machinery. For example, in Hunan Province, farmers who meet the conditions for agricultural compensation purchase a designated type of agricultural excavator and receive a government subsidies of up to 50,000 yuan for agricultural machinery.
Large companies lead the industry in the rapid development of agricultural construction machinery, attracting a large number of enterprises, including many well-known agricultural machinery companies, such as China Yiduo, Futian Heavy Industry, Shandong Changlin and other large enterprises have entered the agricultural construction machinery, and now there are still annual New business joins. With the continuous soaring market demand for agricultural construction machinery and the intensification of competition in large-scale construction machinery, some large-scale professional engineering machinery groups such as XCMG also compete for this ever-expanding market through product miniaturization.
It is worth mentioning that, not only by virtue of its own strength, it has achieved the market share of small-scale agricultural construction machinery in the industry, but also achieved the goal of using “Oriental Red†to lead the industry trend. In order to effectively consolidate the leading position of “Dongfanghong†small liquid digging and small loading in the industry, the company has actively pursued diversification and product differentiation by implementing product differentiation competition strategies and guiding market demands in its operations. In the mid-to-high end extension, we constantly develop marketable products and strive to make small and large-scale agricultural engineering machinery products. By relying on differentiated competitiveness, we have further consolidated our leading position in the industry and maintained the market share of small agricultural engineering machinery products. The country's first advantage.
In addition, under the situation of small-scale agricultural engineering machinery products being sold in a hurry, the company has been paying close attention to product quality improvement and cost control. In view of the weaknesses of the product market competition, they formulated a continuous improvement responsibility system for the products, and targeted the problems of small-scale agricultural engineering machinery development from "low to high, from coarse to fine." Increased user satisfaction and loyalty. At the same time, they set up a host cost index to increase manufacturing cost assessment efforts so that products can participate in market competition at a low cost.
In order to expand the market, enhance the company's operating capabilities, and achieve sustainable development, the company has achieved its own unique advantages by using its variety of products and series of products to occupy the market while guiding its sustainable development. The development trend of the industry, coupled with the implementation of the "win-win strategy for manufacturers" marketing program, has made the "Dongfanghong" small liquid digging and small loading market continue to expand its influence.
Agricultural construction machinery encounters "growing troubles"
In recent years, small-scale agricultural construction machinery manufacturers that have grown up like mushrooms after harvest have tried to gain more market shares in order to gain profits. The direct consequence of this is seriously affecting the product quality of agricultural construction machinery. Moreover, due to the current industry is facing the lack of industry standards, lack of market management and supervision, after-sales service system is not perfect, serious product homogeneity, lagging technological innovation and other contradictions, making the rapid development of agricultural engineering machinery encountered a "growth upset". Industry sources said that if these conditions are not improved in time, it will inevitably increase the threat to the booming agricultural construction machinery market, which will restrict the healthy development of the industry.
Agricultural engineering machinery is a low-end product in construction machinery. At present, the country has not yet incorporated unified management. The industrial development is in a disorderly, spontaneous and loose state. The degree of standardization of network construction is low, laws and regulations are not perfect, supervision is absent, and stability is not High, value assessment and quality certification have no standards, market management lags, etc. Due to the lack of industry standards, the lack of effective supervision and management in the market, if not overcome, is bound to restrict industry upgrading.
Agricultural construction machinery manufacturing enterprises, especially some small enterprises, have the problems of low manufacturing level, lagging technology research and development, and weak service awareness. If the manufacturing methods and methods are similar, some companies use common materials to reduce the cost. Most of the important structural parts such as working devices, booms, and frames are used to make CNC cutting, pressing, bending, folding, and welding. The use of large-scale equipment is rare; more simple tools are used, and hand-welding is used for making and forming, which results in rough appearance, poor quality, and low precision of the structural parts. This results in high failure rate of the agricultural engineering machinery and the service life of the whole machine is only 3 to 4 years. It is far below the service life of standard construction machinery.
Quality is the life of the product. However, at present, agricultural engineering products have low technical content and outstanding homogeneity. The concrete manifestation is that there are many mixed enterprises and small companies, and these companies are relatively weak in terms of their technical level, management level and manufacturing level, and they have less processing equipment and poor production conditions. Due to insufficient investment in R&D, the level of R&D and capabilities are greatly reduced. Therefore, following the strategy of product R&D and production, cloning and copying of brand products lead to similar product structure and homogenization, which reduces the technological content of the entire industry.
However, it is gratifying that in recent years, due to the huge market potential of agricultural construction machinery, it has attracted a number of powerful companies to join, such as China One Tractor, Foton Lovol Heavy Industries, Shandong Changlin, Shandong Weichai, Shandong Zhongyou, Shifeng Group, Larger companies such as Shandong Yugong have many varieties, large scales, and strong competitiveness, which will undoubtedly have a positive effect on improving the overall level of agricultural engineering machinery manufacturing.
Optimizing the environment to promote industrial upgrading Industry insiders believe that when any industry shows its huge potential for development, many companies will flock in and make the market in a disorderly state for some time. The rapid development of the agricultural construction machinery market and many problems in its development, if it can be resolved as soon as possible, its healthy development is not a problem.
To this end, industry experts suggest that relevant government departments should publish industry standards as soon as possible to optimize the industrial environment. Introduce market regulations and industry management policies, standards and standards as soon as possible so that under the management of competition and regulation, large-scale agricultural engineering machinery companies with brands, technologies, and strengths can stand out and gradually replace small-scale enterprises to better meet customer needs. Promote the upgrading of agricultural construction machinery industry.
Improve service system and strengthen after-sales service. Agricultural construction machinery enterprises shall establish corresponding after-sales service systems and after-sales service models according to their own strengths, development stages, business objectives and sales systems. On the basis of the after-sales service system, we will strengthen service-first strategic awareness, increase investment in after-sales service, pay attention to the clarification of after-sales service objectives at different times, enhance the important position of after-sales service departments, and pay attention to innovation in after-sales services. The ultimate goal is to improve the service strategy, form a stable, development potential, and be able to continue to spread through the oral or advertising effect of the customer segment.
As soon as possible the introduction of safety regulations for agricultural construction machinery. The main target farmers for the use of agricultural construction machinery are farmers. Due to the low cultural quality of the farmers, it is determined that the agricultural construction machinery requires high safety. Production companies should use safety as a priority issue, strictly control quality, improve product quality, and increase the use of safety factors; government agencies should promptly issue “Safety Code for Agricultural Construction Machinery†to strengthen the management of product safety. Supervision.
Manufacturers must intensify product innovation and produce products that meet market needs. With the development of agricultural engineering machinery in recent years, market demand and products are constantly changing. The production and management of enterprises should be guided by market demand, continue to develop marketable products, increase product innovation, and implement product differentiation strategies so as to make this gold industry bigger and stronger.
â‘ Single acting cylinder: only one end of the cylinder has a piston rod. Air is supplied from one side of the piston to generate air pressure. The air pressure pushes the piston to produce thrust to extend and return by spring or self weight.
â‘¡ Double acting cylinder: supply air alternately from both sides of piston, output force in one or two directions.
â‘¢ Rodless cylinder: general term for cylinders without piston rod. There are magnetic cylinder and cable cylinder.
The reciprocating cylinder is called swing cylinder. The inner cavity is divided into two parts by the blade, and the air is supplied to the two cavities alternately. The output shaft swings, and the swing angle is less than 280 °. In addition, there are rotary cylinder, gas-liquid damping cylinder and stepping cylinder.
Compared with the electric actuator, the cylinder can work reliably under harsh conditions, and the operation is simple, and the basic maintenance free can be realized. Cylinder is good at reciprocating linear motion, especially suitable for industrial automation in the most transmission requirements - workpiece linear handling. Moreover, only adjusting the one-way throttle valve installed on both sides of the cylinder can simply achieve stable speed control, which has become the biggest feature and advantage of the cylinder drive system. Therefore, for users without multi-point positioning requirements, most of them prefer to use cylinder from the perspective of convenience. At present, most of the applications of electric actuators in the industrial field require high-precision multi-point positioning, which is the result that it is difficult to achieve with the air cylinder.
The electric actuator is mainly used for rotating and swinging conditions. Its advantage lies in the fast response time and the precise control of speed, position and torque through the feedback system. But when it needs to complete the linear motion, it needs to be transformed by mechanical devices such as toothed belt or screw rod, so the structure is relatively complex, and there are high requirements for the working environment and the professional knowledge of the operation and maintenance personnel.
advantage
(1) The requirement for users is low. The principle and structure of the cylinder are simple, easy to install and maintain, and the requirements for users are not high. Electric cylinder is different, engineering personnel must have certain electrical knowledge, otherwise it is likely to be damaged due to misoperation.
(2) The output force is large. The output force of the cylinder is proportional to the square of the cylinder diameter; The output force of the electric cylinder is related to three factors: cylinder diameter, motor power and screw pitch. The larger the cylinder diameter and power, the smaller the screw pitch, the greater the output force. The theoretical output force of a cylinder with a diameter of 50 mm can reach 2000 n. for the electric cylinder with the same diameter, although the products of different companies are different, they are basically no more than 1000 n. Obviously, the cylinder has more advantages in terms of output force.
(3) Strong adaptability. The cylinder can work normally in high and low temperature environment, and has the ability of dustproof and waterproof, which can adapt to all kinds of harsh environment. Because of a large number of electrical components, the electric cylinder has high requirements for the environment and poor adaptability.
