Cover film and install shutter

I. Overview

As a new type of agricultural machinery, the tiller is being accepted by the majority of farmers and gradually becomes an indispensable agricultural machine for farmers to farm. There is a boom in sales everywhere, and farmers are buying it in full swing. For the majority of farmers, it is a good thing to solve the difficult problems of farming. However, if good things are not done well, it will become a bad thing. Why do you say so? Because 90% of the engine used in the tiller is an aluminum alloy engine with a fine workmanship and a higher maintenance requirement than the conventional water-cooled diesel engine, the machine is maintained by a maintenance water cooler. , it may be a good thing to turn bad. Originally intended to solve the labor-purchased tiller, it may become a burden. Therefore, we must understand the use, maintenance and repair knowledge of the tiller, so that he truly becomes a good helper for our farming.

Second, maintenance

Maintenance of the tiller In addition to the routine maintenance required on the instructions, the following three sections should be noted.

First, the oil of the tiller, the engine of the tiller is very precise, and the oil is also very demanding. It is necessary to use qualified canned diesel oil, use CC30 diesel oil in autumn and winter, and use CC40 diesel oil in spring and summer. And in strict accordance with the working hours to replace, run-in is the tiller 15-20 hours after the replacement of oil, the second is the work of 50 hours, the third is the work of 100-150 hours. The gearbox must also use diesel engine oil. It cannot use gear oil. Because the tiller is a light machine, it must use low-concentration light load oil, and the clutch of the tiller is the clutch of the type 125 motorcycle used, and the lubricant of the motorcycle is known as the turbine oil, the concentration is very low. If a high concentration of gear oil is used, there is a possibility that the clutch friction lining may stick and the clutch cannot be disengaged. Also the steering of the chain transmission gearbox is to use the spring to position the steering dial. If the oil is too strong, the steering dial cannot be repositioned after the separation, which will cause the steering side to lose power. In addition, the fuel of the tiller is also very important. The fuel must use Sinopec qualified No. 0 and -10 diesel. Because, the oil circuit components of this kind of engine are very precise and very expensive, can be used for a few years with good use, bad use, probably half a day.

The second is to perform the necessary tightening and adjustment in a timely manner. After a certain period of time in many areas of the tiller, some strokes and gaps will increase, requiring the user to make necessary adjustments. Therefore, the user must grasp the following adjustments. Tiller's clutch, reverse gear, throttle, steering, etc. are all operated by pull wire, and the pull wire is easily deformed and elongated. Therefore, adjustments must be made in time by adjusting the screws. There is also a certain gap between the one-axis, two-axis, and two-pair bevel gears of the gear transmission case. After a certain period of time, a certain clearance will be generated. One axis and two axes are adjusted by tightening the rear end screws. The two teams of cone-shaped gears increase steel. Shims to adjust. During use, the necessary tightening is performed every day. However, it is important to note that the screws of the engine should not be easily tightened, mainly screws that are directly on the aluminum alloy housing.

The third is the maintenance of farm machinery. The main reason is to clean and tighten the screws every day after use, correct the deformation in time, and perform anti-rust treatment in winter.

Of course, there is still a lot of maintenance. This is only the main one.

Third, repairs.

This kind of machine looks very complicated, most people are afraid to repair, in fact, is a paper tiger. How to do a good job in the repair of the tiller, we only need to pay attention to the following principles, you can repair yourself:

1, site, machine cleaning. The working environment of the tiller is soil, so when the tiller is faulty, it is necessary to choose a clean site, clean the machine and then repair it. Otherwise, dropping a small component may cause mistakes.

2, the preparation and selection of tools. There are many places in this kind of machine that must be disassembled using special tools, otherwise it is easily damaged and must not be disassembled by force. So choose the right tools and get ready.

3, the principle of disassembly: After the first assembly parts, slicing in order. At the same time pay attention to the marks, gaps, directions, and the position of the screws. If necessary, you can use the pen to make a mark or record it.

4, analyze the cause of the failure. All the faults must have causes. We must find out the reasons, cure the root cause, and treat the symptoms. Otherwise it may cause greater losses.

5, assembly. Clean all the parts and assemble them in the reverse order of disassembly. The last one is not much, one is not less. Similar to the requirements of the filming of other greenhouses (common arch sheds and vegetable greenhouses), in order to create more appropriate environmental conditions such as temperature and light for the growth of vegetables, it is recommended to select high light transmittance, high mechanical strength, and resistance to aging, and no drops and fog. Excellent performance of the film, EVA film, PO film is more appropriate.

After the film is ready, you can choose to cover the film on a sunny, windless morning. In comparison, the new high-temperature arch sheds are more complicated than ordinary sheds and vegetable greenhouses. Taking a large arch shed with a span of 22.11 meters as an example, it is necessary to cover four shed membranes, one on each side of the middle shutter cradle (the width after processing is 2.9 meters, and the other is more than 40 cu About centimeters, used to cover the gap between the two films, it is about 3.3 meters). The remaining two are each a shed film on the roof of the east-west roof. The width of the roof can be measured with a long rule to ensure accuracy.

In addition, during the process of covering the shed film, especially when covering the columns on the east and west sides, it is recommended that you first wrap the ribs around the arches of the side columns and the outcrops of the bamboo worms to prevent damage to the new shed film.

After the cover film is covered, the shutter can be installed. (Note: This type of large arch shed must be installed because it is inconvenient to manually pull the grass cover).

In practice, it has been found that a new type of high-temperature large-arch shed should use a 34-watt screw-type roller shutter (also called a pull-type roller blind), instead of a rear-mounted roller blind. The reason is that if the latter two things do not start synchronously, it is very dangerous to easily collapse the entire shed body.

The roller shutters in this booth can be placed on a special roller shutter bracket in the middle of the roof. The height of the screw is about 50 cm from the top surface of the booth, and the matching pull rope is selected. The grasshopper in the west. The installation method is as follows:

1. Make a roll rod. It is made of two 6-millimeter-weighted 1.5-inch steel tubes welded with an inner tube, which can be used as a 12-meter universal roll rod.

2. After the shutter is installed and adjusted, the machine is filled with oil. The butter is coated with butter, three-phase power is turned on, and the shutter is operated by turning the switch back and forth several times. Finally, the screw is turned to the maximum position, but there must be about 5 cm of wire remaining.

3. Use a long meter ruler to measure a 12-meter-long position from the head of the long-barreled bar head to the direction of the north head of the shed, if it is in the middle of the two brackets, about 50 centimeters from the front bracket, or about 1.5 meters from the rear bracket. , then even if this roll is suitable, and remember the order, ready for installation.

4. Then continue to the north part of the shed where the measurement is taken. At this time, if the distance is 12 meters, if it is less than 30 centimeters from the front bracket, then it can be cut off by 30 centimeters to make it 1.7 meters to meet the requirements. If it is more than 50 centimeters from the front bracket, it will meet the requirements without cutting. In addition, if it is less than 1.5 meters from the rear bracket, it can be connected to a section of the head from the rear bracket 1.5 meters or more, and so on.

In short, as long as the head is about 50 centimeters away from the stent, or not less than 1.5 meters from the stent, it meets the requirements of the shutter. Also note that the last roll requires 1.6 meters more.

5. In the same way, measure the length of the rod in the south of the shed. Note: The length of the last roll rod to the shed bracket should be an additional 20 cm.

6. After the volume of the two roller shutters is good, in accordance with the order of the windings of each roller blind, drill 8-10 mm holes in the two ends of each bar, and the hole is about 4 cm from the club head. The inner drive shaft is a 1-inch thick-walled steel pipe, which is about 18 centimeters long. The distance between the two drill holes is 9-10 centimeters. Use a propeller shaft to connect each roll rod and the shutter with a screw and turn the shutter by hand. After the test is completed, fix the bracket with a ∪-type screw and install an angle of 55 centimeters in the shed. Make it welded to the stand column. In this way, the shutter system is installed.
