In recent years, the corn combine harvester has become a new tool for farmers after the harvest of wheat and rice. How to properly select, use, and maintain the corn combine harvester to achieve the best economic benefit is the issue that people are most concerned about. In order to properly function the corn combine harvester, ensure the quality of the work. Below, the selection, use, and maintenance of corn combine harvesters are briefly described as follows:
First, how to choose the right corn combine harvester
1, to buy products with high integrity.
Before purchasing, it is necessary to inspect the support rate, user satisfaction rate, product complaint rate, product return rate, product return rate, and patented technology ownership of the enterprise. It is necessary to guard against fake and fake counterfeit products, so as to avoid unnecessary losses.
2. The service radius of the after-sales service center, station, and point (generally within 100 kilometers) is important to the after-sales service quality.
After-sales service quality to a certain extent determines the efficiency of corn harvester operations. To implement in detail, fully prepare to increase the effective rate of corn harvesters.
3, to consider product quality and after-sales service issues.
From the aspect of product quality, it is necessary to purchase mature products that have been established. From the aspect of after-sales service, when selecting the harvester, it is necessary to examine whether the sales and production units have the product “Three Guarantees†capability and whether they can supply spare parts in a timely manner; at the time of purchase, the “Three Certificates†(Product Certificate, Three Guarantees) shall be investigated. Credentials, operating instructions) are complete.
Second, the safe and standardized use of corn combine harvester
1, before the preparation of the job
(1) Check whether the welding parts have cracks, deformation, whether the wearing parts are damaged, whether the claws of the straw crusher, the transmission belt, the chains of various parts, the gears, the steel wire ropes, etc. have serious wear and remove the hidden troubles.
(2) Start the engine and check whether the lift suspension system is normal and whether the operating mechanism, indication signs, lighting and steering system are normal. Engage the power and gently loosen the clutch to check whether the working components of the unit are normal and whether there is any abnormal noise.
2. Precautions when working
(1)Before the operation, the clutch of the working part should be smoothly integrated. The throttle can be operated from small to large until the rated speed is stable.
(2) The driver should observe and listen to the operation of various parts of the machine at any time during the work. If any abnormality is found, he should immediately stop and extinguish and troubleshoot, and do not allow the machine to be sick.
(3) When the unit is in the direction of turning, land transfer or long-distance air transportation and transportation, the harvester must be taken off the power; in the long-distance walking and transportation, the hanging corn combine harvester should cut the header and chop The hooks are hung on the rear suspension frame and can only be driven at a medium speed. The crew is strictly prohibited from overloading except for one driver.
(4) In the case of mechanical transfer, pay attention to the safety of passers-by. Pay special attention to the restricted-travel signs (power lines, trees, restricted height signs, bridges and culverts, etc.) during the journey.
(5) Work first with a low I block test cut, if properly working and then increase a gear properly, harvest a distance, should stop checking the harvest quality, observe whether the appropriate adjustment of various parts, no abnormalities before entering the normal operation. In order to facilitate the unloading of food trucks and personnel, a lane was first opened in the middle of the ground, and then the land was cut off to make a turn for the land.
(6) During the operation, check the quality of cut and crushing and keep the height of the cut, and adjust the height of the header at any time.
(7) Clean the radiator and supplement the cooling water to prevent the engine water temperature from being too high.
(8) When the engine cooling water temperature is too high, you should stop cleaning the radiator and add cooling water in time, but do not immediately open the tank cover to prevent burns. After cooling for some time or taking protective measures, open the tank cover again. Cooling water.
(9) After working for a period of time, the work of the corn harvester should be interrupted for 1 to 2 minutes to allow the working parts to run empty so as to exclude all the remaining ear and kernels from the working parts, and it is not allowed 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 combine harvester to increase, and the parts will be damaged.
(10) Raise the header to the transport position when turning or working along the corn line. When working in a trench, you can only work in the direction of the gutter.
(11) According to the number of grains dropped on the ground to check the operation of the picking device, the loss of grain should not exceed 0.5% of the total corn grain. When the loss is large, check whether the working gap between the picking boards is appropriate.
