When the busy season is busy, the agricultural machine "health" cheats are offered.

[ China Agricultural Machinery Industry News ] Now the value of the north and south early rice transplanting, North China region is about to receive wheat, must check and maintain agricultural machinery before use, in order to avoid accidents when using, resulting in a wrong time. The agricultural machinery "health" cheats, let your home agricultural machinery serve for a longer time!

When the busy season is busy, the agricultural machine "health" cheats are offered.

What happened to the agricultural machinery? Look at the agricultural machinery "health" cheats!

New agricultural machinery use precautions

First, read the instructions carefully

After buying a new machine, before using the engine, you should first read the instruction manual of the machine carefully.

For the basic requirements of the book, users should pay special attention to:

★ Use the specified grade of fuel, fully precipitate and filter before use, keep the oiler clean.

☆ Lubricating oil should be kept clean, the amount should be enough, and it should be replaced regularly. The use of the grade should be consistent with the regulations.

★ Air filter should always pay attention to maintenance.

☆ Pay attention to adding cooling water, especially not to make the engine work in the absence of water.

★ Always pay attention to the inspection, tighten the relevant bolts and nuts, especially the connecting rod bolts, the bolts on the drive shaft and the lock nut on the flywheel, the tightening nut of the wheel, etc.

Second, the test run run-in

After buying a new machine, do not load it immediately, and test it in accordance with the requirements of the manual. After the running-in is finished, the machine oil filter is cleaned and the residual impurities in the oil are removed. If necessary, the oil is replaced and the oil pan is cleaned.

Third, use within the rated range

When the new machine is working, it must be done in strict accordance with the manufacturer's instructions. It is not overloaded, does not overspeed, does not feed, and does not work for a long time.

Fourth, do not arbitrarily modify the machine

It is not possible to modify the new agricultural machinery and arbitrarily increase the engine speed. In order to make the machine run faster, some users adjust the oil supply and supply pressure of the high-pressure oil pump at will, and some of them use the wire of the speed-regulating spring to tie it up, which is even more wrong.

Agricultural machinery use maintenance tips

First, check the crack

Once the parts on the machine are cracked, do not use them. But how do you tell if a part has cracks and cracks? Soak the suspicious parts in kerosene for 30 minutes, remove the dry surface, and apply a layer of chalk ash on the surface. After a while, the chalk ash absorbs the kerosene oozing out of the crack, making the cracked place become Black, you can find the cracked part of the part.

Second, clever tires

First remove the rust on the rim, apply a thin layer of talcum powder between the inner and outer tires, then lay the rim flat and put on the tire. Use a pedal or crowbar to pry the rim of one side of the tire into the rim, place the inner tube, and fix the inflation valve in the rim of the rim valve with a wire, and then install the other side of the tire. Starting from the corresponding position of the inflation valve, a part of the tire is first plunged into the rim by a crowbar, and then gradually installed from the inflation valve to both sides, and the tread which is opposite to the inflation valve is pressed with the foot, and the tread is pressed on the side. The bead ring portion of the tire casing is gradually loaded into the rim.

Third, cleverly installed oil seal

When the oil seal is mounted on the crankshaft, the inner end surface of the seal is easily twisted, resulting in oil leakage. Roll a clean thin hard paper into a trumpet-shaped reel, put the reel on the shaft, place the small end of the reel on the shaft end, put the oil seal on the small end of the reel, and gently put the oil seal by hand. Rotate on the shaft, the direction of rotation is consistent with the roll direction. When the oil seal is in place, slowly withdraw from the roll.

Fourth, skillfully remove the water tank

For example, when disassembling the Dongfeng-12 type walking tractor water tank, it is often difficult to disassemble because the water tank bolt is corroded and the bolt is installed in the water tank. Put a 17mm plum wrench on the head of the hex bolt and take a wooden stick or iron rod that is 1 meter long. The lower part of the hammer is placed against the handle of the plum wrench, with the upper edge of the water tank as the fulcrum, and the lever is used to gently pull the water tank. The bolts can be loosened. If the hex head of the water tank bolt is rusted or slippery, use a long chisel (no sharp edge) to align the edge of the hex head and dig it in the direction of loosening; if it is not chiseled many times, you can dig the hex head until the water tank is taken out. Drill and tap on the body.

Five, clever check cable disconnection

The cable for the water pump is prone to breakage due to repeated folding and twisting during use. Use a 220V power plug to connect a 220V, 15W bulb to one of the power cables. Connect the two power cables to the two ends of the cable. After the power is connected, the bulb lights up to indicate the line. Otherwise the core is broken. At this time, hold the cable with both hands and squeeze it in the middle for a while. If the light is on, it means the wire is broken. Disconnect the power supply, cut the rubber sleeve with a knife, connect the broken wire, and then wrap it with insulating tape.

If you actually do the basic requirements of the above, the life of the agricultural machine will be greatly extended. Insert rice, wheat harvest soon, follow the above methods, check your own agricultural machinery!
