In May, I saw the rapeseed harvester for the first time in the rapeseed field in our province that just entered the mature harvest. The rape harvesting machinery technology has become a topic of concern for farmers. What are the technical points of rapeseed machinery harvesting? On May 10, the reporter interviewed Wang Biao, the head of the sales and marketing center of Jifeng Agricultural Machinery Chain Co., Ltd.
Reporter (hereinafter referred to as the record): What conditions should the operator have?
Wang Biao (hereinafter referred to as Wang): The operator should correctly grasp the use method of the harvester, and must pass the technical training and obtain the driver's license before the actual operation; it is forbidden to wear clothes that are loose or can not be buckled, so as not to be hung by the rotating parts. Living causes injury; it is forbidden to wear headscarves, scarves, etc. that are easily caught in the implement.
For the first time operator, please work at low speed before being proficient.
Remember: How to do security check?
Wang: When checking, adjusting, cleaning, refueling, and replenishing the butter, the engine must be stopped; the clutches should be placed in the off position and the handbrake should be locked; if there are piles of grass around the muffler, the belt cover, the battery, and the fuel tank It may cause fire. Please clean the grass clippings. All safety covers must be closed or fixed before starting the machine. Do not open or remove the safety cover after starting the machine. Valve rotor pump
Reporter: How to move on the road (field) to be safe?
Wang: It is necessary to confirm the safety around when advancing, reversing and turning; when driving on a soft road surface, do not drive near the roadside, the harvester may collapse the road; high-speed cornering is strictly prohibited.
Remember: Pay attention to harvesting?
Wang: If you encounter any abnormal situation, you must stop the engine immediately; do not approach the header, because the cutter, reel and other positions will produce shearing phenomenon, causing damage to the body; when clearing the header straw and weeds, you must wear Thick gloves to avoid being cut by the cutter; high-speed rotating parts in each observation cabin and cleaning port, can never be opened during operation; there are dangerous rotating objects in each belt and chain cover, and do not put your hand into the operation.
There are rotating parts in the grain box, and the hands and other parts of the body are absolutely not allowed to enter the grain bin during work. If you need to enter the grain tank, you should stop the engine first, and confirm that all working parts have been stopped. Someone assists to enter the grain tank and hangs the warning sign of someone in the grain box.
The trough and drum are easy to block, and the engine must be stopped when cleaning up the blockage.
When working, it is strictly forbidden to stand at the grass drain and the discharge port to prevent splashes from injuring people.
When using a height of more than 10 cm, use a springboard. When crossing a field less than 10 cm, walk at a low speed vertical field.
Note: What problems should be paid attention to by manual threshing?
Wang: Combine harvesters are generally not used for fixed threshing in the field. When used as fixed threshing in the field, remove the reel drive belt and cut off the cutter drive; when loosening the hand, you should not wear loose cuffs and gloves.
Remember: How to check and repair?
Wang: Inspection, repair and maintenance shall be carried out in a flat place and the engine shall be stopped; when the header is inspected, the header shall be locked with a safety lock.
Pay special attention when inspecting the drive parts such as chains and belts and the cutter parts. There is a risk of shearing in these parts.
When the threshing drum is clogged, shut down the engine and use a crowbar to turn the drum to clean.
Remember: How to check the battery?
Wang: When removing the battery, first remove the negative (-) side, and when installing the battery, first install the positive (+) side.
When opening the battery, avoid contact with the electrolyte. If it is inadvertently contacted, immediately rinse it with clean water; there is a danger of explosion when the electrolyte flows out, so the battery cannot be close to the open flame.
Remember: Which conditions are prone to burns? How to prevent the risk of burns?
Wang: Engines, water tanks, silencers, exhaust pipes, hydraulic oil and other parts will become high temperature after operation, so do not touch immediately after operation or just after stopping, so as to avoid burns.
When the engine generates high temperature, it should be stopped by the engine for more than 30 minutes to open the engine room, and then open the radiator cover to remove the pressure of the steam before working.
Remember: How to prevent fire hazards?
Wang: It is necessary to clean the grass clippings around the engine, battery and exhaust pipe components, otherwise it will cause fire.
Damage to the outer skin of the wire may cause a short circuit and cause a fire. Always check and repair the damaged part.
The fire extinguisher is an essential accessory for the harvester. When the harvester goes out or in the field, it must be equipped with a fire extinguisher and check whether the fire extinguishing agent is within the validity period.
The fire extinguisher is placed in front of the grain bin.
The correct use of fire extinguishers:
When extinguishing the fire, carry the fire extinguisher, pull out the safety pin, and at the effective distance from the fire surface, align the nozzle with the root of the flame, press the pressure roller, and push the spray.
Be quick and decisive when extinguishing fires, leaving no open flames to prevent re-ignition. Do not hit the liquid surface to prevent splashing and cause fire extinguishing.
