Buy a good farm machine to grasp four methods

How to buy good quality agricultural products? By visiting agricultural machine users and agricultural machinery sales departments, the author believes that it can be grasped from four aspects. One is to look at the data, that is, to see if it is complete with random documents. The instructions and product certifications of the agricultural machinery product structure, working principle, use and maintenance, three-package service (warranty card), etc. shall be introduced in detail; the diamond-shaped agricultural machinery promotion permit badge shall be attached to the conspicuous position of the fuselage; Application of the nameplate logo, including the main parameters of agricultural machinery, manufacturer name, address, implementation of the standard code, production license number (threshing machine, diesel engine, submersible pump); buy agricultural products that have high value or cause accidents due to quality problems, The dealer shall also be required to present the inspection report of the agricultural inspection department. The second is to observe the appearance, that is, to carefully observe the appearance of agricultural machinery products. Mainly from the vertical and horizontal angles to observe the entire machine with or without deformation, the appearance of the entire machine is missing paint, serious scratches, bubbling and other phenomena, metal materials must be painted with anti-rust paint primer, machine cover, Sheet metal parts should be smooth and so on. The third is to check the assembly, which is a detailed inspection of the machine assembly. Check whether the parts and components of the agricultural machinery are intact and error-free and whether the installation specifications are correct. All non-adjusting screws, bolts and nuts shall be tightened firmly and locked according to the specified locking method. It is forbidden to use wire or nails instead of cotter pins. All rotation, transmission and operating devices of the agricultural machine are flexible and have no cassettes. Have a reliable safety protection device. Any place on the agricultural machinery that may cause harm to the user's personal safety should be equipped with safety protection devices. There must be a permanent warning sign on the site of an accident. The fourth is to retry the machine. When the farm machine is purchased, a start-up test must be performed. In particular, transport machinery such as tractors, combine harvesters, agricultural vehicles, etc. must pass tests to understand whether the maneuverability is good, whether the engine runs smoothly during operation, whether the combustion and engine sounds are normal, and whether the direction, brakes, and throttles are sensitive and reliable. The agricultural machinery (thresher, shredder, etc.) should pay special attention to the balance of the machine drum. The machine with a pressure vessel (motorized sprayer, etc.) should be tested to see if its pump pressure can reach the specified value. Whether the role is correct, whether there are leaks in the pipes and joints and so on.
