What are the details of using ground drills?

The use of ground drills is a revolution in productivity. In my country's production, the use of machinery is expanding very quickly. It has not been very long since it entered the domestic market in my country, so there are not many reference materials on the Internet, when people encounter problems during use, there is almost no solution except the manufacturer. In order for people to master a good method of use, they need to pay good attention to the following details of use.

The spark plug of the ground drill should be cleaned well before each work. Only after cleaning, the filter can be guaranteed to work well. Mainly if you want the machine to be used well, you must perform a good service life on it in time. Maintenance, during use, the carbon deposits on the filter should be cleaned regularly. After a period of time, according to the intensity of use, they should be carefully inspected, and the surface should be removed in a timely manner. Oil stain cleaning.

Often after being used for a period of time, they will be left for a long time. This situation often occurs in winter, because the frequency of planting is reduced and the scope of use is also reduced. Good maintenance must be carried out before being placed, such as , pour out all the fuel in the fuel tank, and then start the ground drill to burn the internal fuel cleanly. This effectively ensures that the next time it is used, the fuel will deteriorate due to the deterioration of the fuel, which will cause problems during use. Difficulties.

During use, during high-speed operation of the machine, avoid temporary shutdowns, which may cause serious damage to the mechanical performance of the engine. Therefore, for people, emergency shutdown is required for earth drills during use. When doing this, you need to adjust the power first, and then shut down the machine. This ensures that damage to the engine caused by a quick stop is avoided.

It should be noted that the gasoline used in ground drills should not be pure gasoline, nor should it be gasoline containing too many impurities. It should be oil with excellent characteristics and a fusion of engine oil and gasoline. For its The ratio should be blended according to 25:1. Only by strictly following this ratio can we ensure the good effect of mechanical operation efficiency.

Adjustment of the tilt of the cotton picking head

By adjusting the length of the booms on both sides of the cotton picking head beam, the front roller is 19 mm lower than the rear roller when the machine is operating, which allows the picking spindle to contact more cotton and allows the residue to flow out from the bottom of the cotton picking head. The length of the boom is a pin-to-pin distance of 584 mm. The two lifting frames should be adjusted uniformly, and the inclination adjustment should be performed within the cotton row.

Adjustment of pressure plate gap

The distance between the pressure plate and the tip of the spindle can be adjusted by adjusting the nut on the hinge of the pressure plate, which is about 3 to 6 mm. Through practice, it should be adjusted to a gap of about 1 mm between the pressure plate and the tip of the spindle. The cotton will leak out, and if the gap is too small, the spindle will make deep grooves on the pressure plate and damage the components. Even the friction between the spindle picker and the pressing plate can produce sparks, which can become a hidden danger of machine fire.

Adjustment of pressure plate spring tension

This is achieved by adjusting the relative position of the adjusting plate and the round hole on the bracket. From rotating the adjusting plate until the spring just touches the pressure plate, the front cotton picking head continues to rotate and adjust to 3 holes on the adjusting plate, and the rear cotton picking head is adjusted to 4 holes, align with the fixed holes on the bracket, insert the flange screws, and can also be adjusted to 4 in the front and 4 in the rear. When adjusting, the pressure plate on the rear cotton picker head should be adjusted first, and the pressure plate on the front cotton picker head should be tightened only when necessary. If the spring pressure is too small, the picked cotton will have less impurities, but more cotton will be left behind; if the pressure is too high, the picking rate will increase, but the cotton impurities will increase, and the wear of the machine parts will increase.

Adjustment of the height of the doffing disc group

Adjust the position of the cotton picking drum until a row of picking spindles on the drum are aligned with the slots on the chassis. At this time, the friction resistance between the doffing disk group and the picking spindles is slightly swayed by hand. Resistance prevails. When the gap is not appropriate, you can loosen the locking nut on the doffing disc column, adjust the adjusting bolt on the doffing disc column, and turn it counterclockwise. The gap will become larger and the resistance will be smaller. On the contrary, the smaller the gap will be, the greater the resistance will be. During the operation, adjustments should be made according to the winding condition of the spindle.

Adjustment of humidifier column position and height

Position: The position of the humidifier should be such that when the spindle is removed from the moistening plate, the first wing of the humidifier pad just touches the front edge of the dust guard for the spindle picker. Height: When the spindle just passes under the humidifier plate, all the tabs should be slightly bent.

Filling and pressure adjustment of cleaning fluid

The ratio of water to cleaning fluid is: 100 liters of water to 1.5 liters of cleaning fluid, mix thoroughly. The cleaning fluid pressure display reads 15-20 PSI. The pressure should be lowered when the cotton is wetter and raised when the cotton is drier.
