Applications and common problems of micro tillage
- Jul 11, 2017 -

First, the use of micro tillage:

The micro tillage machine has the characteristics of light weight, small volume and simple structure. With the implementation of the purchase subsidy policy of farm machinery, micro tillage machines have been widely used in agricultural production. Not only in the plain, mountainous, hilly dryland, paddy field plowing, harrowing operation, with the corresponding equipment can also be used for power generation, pumping and spraying spraying operations. Micro tillage machine is convenient for farmers to use and storage, eliminating the large agricultural machinery can not enter the mountain field troubles.

This year, the Midu county will be used to dig the small irrigation machine garlic. Digging garlic with a micro tillage machine not only saves the cost, but also improves the work efficiency. General artificial big garlic, one mu of farmland to employ 10-15, with micro tillage machine to dig big garlic, generally 2-3 hours can be. Micro tillage machine in front of the big garlic turned up, 4-5 people in the back to pick garlic, operation speed slowed down a bit, turn 3 times field can put big garlic clean. An acre of garlic can save more than 8.

Two, common problems:

1, cooling water cooling. Some of them saw the higher temperature of the air cooler, worried about damaging the machine, and helped cool it down by watering. Is actually very wrong, sudden cooling water, the cylinder suddenly shrink, easily broken ring, cylinder, cylinder and even rupture.

2, do not pay attention to class maintenance. Some hands think that a few days to do a maintenance on the line, in fact, wear and tear is a process of accumulation, class maintenance is as good as the main.

3, do not pay attention to the quality of fuel oil and lubricating oil. Poor fuel quality, not only the power of the machine is not enough, but also to speed up the oil pump and core wear; the quality of lubricating oil directly affect the machine's starting performance and service life, must not be careless. Yichang Yao Wan Xiang Shahe Cun Lu Qibing to reflect his machine has been used very well, because there is a lack of operation of lubricating oil, plus a renewable oil, the machine performance declined, finally after overhaul to solve the problem.

4 、 improper use of sealant for engine eccentric gasket. Partial cover pad using the sealant, the excess glue easily into the gear box, because of long time working and suction pump, it is easy to plug the oil into the oil sealing hole, so that the crankshaft and connecting rod without effective lubrication.

5, fuel tank cover oil leakage sealed with film paper. After sealing the fuel tank, a long time work in the tank produces negative pressure, resulting in insufficient oil intake, making the machine black smoke at work, lack of power.

6, diesel atomization is bad, only change nozzle. The diesel oil atomization is bad, except the oil nozzle problem, it is the high-pressure oil pump to wear, the pressure is small, the oil quantity is few.

7, screw the screws on the tight block. Micro tillage machine is equipped with multi Aluminum Alloy box engine, Aluminum Alloy is clearly less than the hardness of nodular cast iron in the body, so all the screws must be in accordance with the prescribed torque force, especially the cylinder head screws, little attention will be drawing "". And try not to screw tight in a heat engine.

8 、 dismantle the wind shield and windshield of the air cooler. Some hands do not know the role of the wind shield and wind deflector, that is something to block the soil, you can not, any disassembly, resulting in fan wind can not be concentrated, lost the effect of cooling.
