The usage method and maintenance of household hay cutters

The usage method of household hay cutter

(1) The hay cutter should be placed or fixed on a solid and level foundation. When in operation, it should be stable and avoid significant vibrations.

(2) Before starting the machine, a comprehensive inspection of all its components should be carried out first. Rotate the blade shaft of the hay cutter by hand to check if it rotates smoothly, if there are any cracks in the blade disc, and if the fasteners are loose. Any potential faults found should be eliminated in time.

(3) Before starting the operation, let the hay cutter idle for a while to observe whether the operation is smooth and if there are any abnormal sounds. Only after confirming that the operation is normal can it be put into operation.

(4) Feeding should be uniform. If too much is fed in, causing the speed of the knife shaft to decrease, the machine should be stopped for cleaning.

(5) Before processing feed, all impurities in the feed should be removed to strictly prevent hard objects such as iron parts and stones from being fed in along with the feed.

(6) If grass blockage occurs during operation, the clutch should be disengaged immediately and the machine stopped to eliminate the fault. The protective cover must not be opened when the machine is in operation.

(7) Before the operation is completed, stop feeding first. Wait until all the materials inside the machine are discharged, then disengage the clutch and cut off the power supply. Clean up all the debris inside the machine.

Maintenance and upkeep of hay cutters

(1) Regularly check if all fasteners are loose and tighten them.

(2) Strengthen the maintenance and upkeep of bearing housings, couplings and transmission boxes, and add or replace lubricating oil and grease on a regular basis.

(3) For hay cutters with adjustable cutting gaps, the cutting gap should be reasonably adjusted according to the thickness of the crop stems to ensure the normal operation of the hay cutter.

(4) When the cutting edge of the blade is found to be blunt, an oilstone should be used to sharpen the moving blade.

(5) After each shift's work is completed, the dust and dirt on the machines should be removed in a timely manner. After the end of each season's operation, all debris inside the machine should be removed, anti-rust oil should be applied to the working parts, and it should be placed in a well-ventilated and dry indoor area.

Diagnosis and Elimination of Common Faults of Hay cutters

The grass cutter can not only cut various fresh and dry grass and straw, but also be used for processing livestock forage and silage. It can also be used for returning straw to the field and cutting green weeds for 沤肥. It is particularly suitable for rural breeders to purchase and use. The following is a detailed introduction to the diagnosis and troubleshooting methods of common faults of hay cutters:

The correct operation method is that the machine must be used and maintained by designated personnel. The user should carefully study the machine's operation instructions, understand its structure and performance, and master the professional skills of using the hay cutter proficiently. Second, unauthorized personnel are strictly prohibited from entering or walking around the work site, and children are not allowed to play there to prevent any disruption to the work and potential accidents. A dedicated area for stacking forage and a working surface horizontally connected to the feeding hopper should be prepared to facilitate the stacking of forage and ensure the continuous feeding of forage. Thirdly, tools for cleaning forage should be available. When processing, all impurities, iron and stones and other hard objects in the forage to be processed must be removed; otherwise, they may enter the machine and damage the blades or other components. Fourth, after starting the vehicle, the operator's hands must not enter the feeding room to prevent accidents. If grass blockage occurs at the feeding inlet, the switch should be immediately pulled to stop the machine and the fault should be promptly eliminated. When the machine is in operation, it is strictly forbidden to push the blocked grass by hand or with wooden or iron rods to prevent cutting hands or fingers or being injured by wooden or iron rods, which may cause personal injury. In addition, fire prevention should also be noted to avoid causing fires. The fifth point is that the workplace should not be too close to power sources. When repairing, maintaining or troubleshooting, the power switch must be turned off and the machine stopped before proceeding. Do not carry out the work while the machine is running.

Note: If users encounter problems they cannot solve during the operation of the hay cutter, they can consult the manufacturer, Linyi Hedong District Dahua Machinery Factory, at any time: /. Linyi Dahua Machinery Factory's hay cutter *, with excellent service.

Maintenance and troubleshooting of hay cutters

If the hay cutter is not operated properly during use, mechanical failures are likely to occur, which will affect work efficiency. Therefore, do not neglect the maintenance and upkeep of the hay cutter.

Key points for maintenance and repair. Before starting the work, it is essential to inspect and adjust all parts in accordance with the regulations. Only when the requirements are met can the work proceed. The moving and fixed blades of the hay cutter should always be kept sharp. Otherwise, they should be removed in time for grinding. The bearings on both sides of the main shaft and the feeding roller shaft have been injected with grease during installation. After one month of use, the above bearings need to be removed, cleaned thoroughly, and then re-lubricated with high-quality grease (good quality grease) before reinstallation and use. After that, lubricate once every month of operation. Other rotating parts should also be frequently lubricated with engine oil during use. In addition, it is necessary to frequently inspect whether the components of the hay cutter are damaged, severely worn or loose, especially the working parts and rotating parts. If any damage, severe wear or looseness is found, it should be replaced, repaired and tightened in time to avoid major accidents. When the machine is not in use, the dust and dirt on its surface should be wiped off. If the machine is parked outdoors, it should be covered with tarpaulin to prevent rusting.

2. Troubleshooting Common Faults. When in use, if the hay cutter gets clogged with forage between the upper and lower feeding rollers, the main cause of the malfunction is excessive feeding volume, which leads to grass blockage and entanglement between the lower feeding roller and the bridge. The troubleshooting method is as follows: After parking, manually reverse the large pulley of the main shaft, and the blocked grass will be discharged accordingly. Then, clear the grass stuck and entangled in the feeding roller thoroughly. If the grass sections cut out are too long, the main causes of the malfunction are: large gap between the moving and fixed blades; When the cutting edges of the moving or fixed blades are not sharp and the fault is eliminated, the cutting gap can be adjusted to be smaller, and the blades can be ground to keep the cutting edges sharp.
