Correct use and maintenance of rotary cultivator

Driven by a series of national agricultural policies, China's agricultural machinery manufacturing industry has shown a good momentum of rapid development in recent years. Affected by the continuous increase in tractor market heat, rotary cultivators, one of the main equipments that are matched with it, are gradually becoming hotter, showing a good momentum of rapid development. It is reported that at present, the number of rotary cultivators in China has reached 3.1 million units or more, and the annual output is about 400,000 units. This year, in particular, some brands of rotary cultivators have been included in the national agricultural machinery purchase subsidy list, which makes The cultivator market is thriving. Due to the changes in farmers' farming habits and the adjustment of agricultural planting structure, the market sales of rotary cultivators will be expected to increase further. Rotary cultivators have won popularity among farmers because of their low price and high cost performance. Although more and more farmers are buying rotary cultivators, because farmers have relatively narrow access to information and lack of knowledge of rotavators, there are often misunderstandings and blind spots in the use and maintenance of cultivators. Therefore, they should help. Farmers have more knowledge about the use and maintenance of the rotary cultivator to maximize its usefulness.

First, the correct use of rotary cultivator

1. Check all parts before use. In particular, check whether the anti-rotation knife and the fixing bolt and the universal joint locking pin are reliable. If any problem is found, it must be dealt with promptly.

2. Before the tractor starts, the rotary cultivator clutch handle should be set to the disengaged position.

3, to join the power in the lifting state, until the rotary tiller reaches the predetermined speed, the unit can start, and the rotary tiller slowly down, so that the rotary tiller into the soil. It is forbidden to start directly with the rotary tiller in case of soil, so as to prevent the rotary tilling knife and related parts from being damaged. It is forbidden to rapidly descend the rotary tiller, and it is prohibited to reverse and turn the rotary tiller after entering the soil.

4. When the ground turning does not cut off the power, the rotary cultivator must not be lifted too high. The transmission angle at both ends of the universal joint must not exceed 30 degrees, and the engine speed should be properly reduced. When transferring the land or walking long distances, the power of the rototiller should be cut off and locked after it is raised to the highest position.

5. When the rotary cultivator is in operation, it is forbidden to approach the rotating parts, and no one behind the rotary cultivator is allowed, in case the blade throws wounds.

6. When checking the rotary tiller, you must cut off the power first. When replacing rotating parts such as blades, the tractor must be turned off.

7, the speed of advancement during farming, dry fields to 2 ~ 3 km / h is appropriate, in the land has been ploughed or rigged to 5 ~ 7 km / h is appropriate, in paddy field cultivation can be appropriate faster. Remember that the speed cannot be too high to prevent the tractor from being overloaded and damaging the PTO shaft.

8. When the rotary cultivator is in operation, the wheels of the tractor should be walked on the uncultivated land so as not to compact the arable land. Therefore, the tractor wheelbase needs to be adjusted so that the wheels are located within the working range of the rotary cultivator. Pay attention to the method of walking during operation to prevent the other tractor from compacting the cultivated land.

9. During operation, if the knife shaft is wrapped around too much grass, it shall be stopped and cleaned in time to avoid increasing the load of the machine tool.

10. When rotating tillage, the tractor and hanging parts are not allowed to take people to prevent accidental injury by rotary cultivator.

11. When using the walking tractor to turn the cultivator, only when the auxiliary shift lever is in the “slow” position, can it be rotated and ploughed. If you need to reverse the work, you must put the sub gear lever in neutral to hang the reverse gear. Rotary cultivating try not to use the steering clutch, apply push and pull handrails to correct the direction. When cornering, you should first reduce the throttle, hold the handrail frame, and then squeeze the steering clutch, do not turn dead bends to prevent damage to parts.

Second, the maintenance of rotary cultivators

“The principle of prevention and treatment of heavy weight and cultivation” is the principle of the use and maintenance of agricultural machinery such as rotary cultivators. Rotary cultivator maintenance can be divided into two types of maintenance and quarterly maintenance.

Under normal circumstances, class maintenance should be carried out after each class of work, including: check the tightening of connecting bolts; check for defects such as bolts, split pins and other consumables, replace if necessary; check the transmission case, ten bytes and bearings for lack of oil If necessary, add it immediately. After the completion of each quarter of work, quarterly maintenance should be carried out. The contents include: the complete removal of dust and oil on the equipment; thorough replacement of lubricants and grease; check if the blades are excessively worn and replace them if necessary; check the hood and pallets. Such as whether there is deformation, if it should be restored to the original or new; a comprehensive inspection of the appearance of equipment, make up paint, machete, spline shaft should be oil rust; long-term non-use, wheeled tractor supporting rotary cultivator should be home On level ground, do not hang on tractors.
