The development of corn harvesting machinery is very fast, and the technical requirements are relatively high. It must be used correctly to ensure the quality of work and extend the life of the machine. The following describes the use of corn harvesters and precautions: 1. Pre-operational inspection. 1 Check whether the installation of the bearings and the high-speed rotating parts (such as the stem cutting device and the intermediate shaft) on the shaft is normal. 2 Check the tension of the V-belt and the chain. 3 Check if there are tools or extraneous items left on the working part of the harvester and all protective covers are in place. 4 Check if the fuel, oil and lubricant are in place. 2. No-load test run. 1 Separate engine clutch, gear lever in neutral position. 2 Start the engine and engage the clutch at low speeds. When all working parts and various mechanisms are operating normally, gradually increase the engine speed until the rated speed, and then make the harvester run at rated speed. 3 During operation, perform the following checks: Start the hydraulic cylinder of the hydraulic system in sequence Check the working condition of the hydraulic system, the sealing condition of the hydraulic piping and hydraulic components, and check the braking condition of the harvester (driving). After every 20 minutes of operation, separate the engine clutch and inspect the bearing for overheating and the transmission of the belt and chain, and the tightening of each connection. When all the gears are used in order to join the working parts, the harvester is commissioned and the parts are observed during operation. The on-the-spot air-manufacturing time of the corn harvester is not less than 3 hours, and the air-trafficking time is no less than 1 hour. 3. Operation test run. During the first 30 hours of operation, the speed of the harvester is recommended to be 20%-25% lower than the normal speed, and the normal working speed can be performed according to the working speed recommended in the manual. After the test run, it is necessary to thoroughly inspect the degree of assembly fastening of each component, the correctness of assembly adjustment, and the working status of electrical equipment. Replace all gearboxes and close the gearbox lubricant. 4. Things to note when working. Before the operation of the corn harvester, the clutch of the working part should be smoothly integrated. When the throttle is from small to large, the harvesting operation can be started only when the rated speed is stable. 2 When the corn harvester is operating in the field, it is necessary to regularly check the quality of the cutting and crushing and to keep the height of the cut, and adjust the height of the header at any time according to the situation. 3 Check the operation of the picking device according to the number of grains thrown on the ground. The loss of grain should not exceed 0.5% of the total amount of corn grain. When the loss is large, check whether the working gap between picking boards is correct. . 4 The corn harvester should be properly interrupted for 1 minute to 2 minutes to allow the working part to run empty so as to remove all remaining corn ear, kernels, etc. from the working part and not to block the working parts. When the working part is blocked, it shall be stopped in time to clear the blockage, otherwise it will cause the friction of the corn harvester to increase and parts to be damaged. 5 When the corn harvester turns or runs along the corn row, it should raise the header to the transport position. In the field where there is a ditch, the corn harvester can only operate along the ditch.
