What matters should be paid attention to when using the capstan sprinkler machine?

Winch sprinkler, also known as reel sprinkler or hoist sprinkler, is a kind of irrigation machine which wraps the traction PE pipe on the winch, uses sprinkler irrigation pressure water to drive the water turbine to rotate, drives the winch to rotate by the variable speed device, and pulls the sprinkler car to move and spray automatically. In recent years, with the aggravation of drought in the north, the application of large growers in the field is more and more.

It is suitable for the irrigation of a large area of farmland, the water pipe is wound around the winch, it is pulled to one end of the area by a tractor, the spray gun is sprayed at the same time, and a rectangular belt is sprayed with the sprinkler truck until the end of the ground. it is a suitable choice for farmland water-saving irrigation.

The working principle adopts the water turbine power drive system, which enters the water turbine through the pressure water and uses the kinetic energy of the water to drive the rotation of the water turbine. The rotation of the water turbine is driven by the multi-function gearbox device to rotate the winch, and the PE pipe is dragged to realize the uniform recovery of the sprinkler car. At the same time, the pressure water is transferred into the PE pipe to the sprinkler head to realize the normal alcohol spraying of the sprinkler head.

The capstan sprinkler irrigation machine is mainly composed of chassis, frame, winch, PE water pipe, automatic speed regulation device, water turbine drive device, gearbox, sprinkler car, guide device, safety device and so on. The machine has the advantages of simple structure, high degree of automation, strong adaptability, convenient operation and multi-stage variable gear. it is one of the ideal water-saving irrigation machines suitable for the situation of our country. Single sprinkler capstan sprinkler irrigation machine is mainly suitable for crops with low atomization index requirements.

Operation adjustment and safety precautions of capstan sprinkler irrigation machine

1. Traction of winch sprinkler irrigation and stretching of PE pipe

Before starting the machine, click each check to confirm:

1. Before starting the machine, please add grease to all the bearings, chains and other rotating parts, and the running parts should lock the shield tightly.

two。 Tighten the wheel nut before starting and check that the air pressure is correct.

3. The wheel distance of the sprinkler is set according to the type of spraying crops and the size of the sprinkler.

4. Place the appropriate counterweight on the balancing hammer of the sprinkler. When the nozzle diameter is Φ 14-24mm, two counterweights are placed; when the nozzle diameter exceeds Φ 24mm, and when the wheel distance of the nozzle is narrow, four counterweights are placed.

5. Set the sprinkler fan angle to ensure that the sprinkler car walks on the dry ground, the fan angle is generally 220-270 °.

Second, transport the machine to the set position

1. When driving on the road, the winch must be rotated and locked with a fixed pin, the PE pipe must be rolled on the winch, the sprinkler must be lifted and covered by a transport protection frame, and the front support and two rear supports must be retracted to the top position and locked with a fixed pin. While driving, the drag rod is hung into the tractor connecting claw. The driving speed must not exceed 10 km / h.

two。 The machine pays special attention to the terrain when transporting in the field, the maximum driving speed must not exceed 5 km / h, and the width of the transportation pipe road is guaranteed.

3. When the sprinkler irrigation machine reaches the working position, adjust the winch so that the running direction of the sprinkler car is consistent with the sprinkler irrigation strip, fix the sprinkler irrigation machine, and lock it.

4. When pulling the PE pipe, first pull out the rotating chassis fixed lock, the rotating winch is in the same direction as the irrigation belt, and then lock the fixed lock.

5. Press the two rear brackets into the ground with a handwheel. If the ground is hard, dig a hole on the ground first, put the bracket into the pit, and then lock the rear bracket with a fixed pin.

6. When the machine is in the working position, relax the mechanically locked position of the sprinkler car, lift the positioning lever up, and carefully press the gearshift lever down, and the sprinkler car becomes slowly lowered. The position of the operator must be outside the machine bracket.

Matters needing attention when using

1. After starting the pump, if the water is not out of the water for 3 minutes, it should be stopped for inspection. If abnormal phenomena such as noise, vibration and water drop are found in the operation of the pump, you should stop immediately and pay attention to the bearing temperature, which should not exceed 75 ℃.

two。 Reel sprinkler irrigation water must not contain a lot of sediment and dirt, so as not to wear or block the sprinkler. It is not suitable to carry out sprinkler irrigation when the wind is above level 3.

3. During the operation of the unit, pay attention to observe whether the sprinkler works normally, whether the rotation is uneven, too fast or too slow, or even no rotation, and observe whether the commutation is flexible and whether there is any abnormal phenomenon.

4. In order to apply to different soils and crops, the nozzles need to be replaced. When adjusting the speed of the sprinkler, you can tighten or relax the rocker arm spring. The rocker arm is suspended on the rocker arm, so it can rotate the adjusting screw and adjust the water entry depth of the rocker head to control the speed of the sprinkler. Adjust the position of the inversion to change the speed of the inversion.

5. Pay attention to whether the intensity of sprinkler irrigation is appropriate, requiring that there is no runoff or stagnant water on the soil surface. Otherwise, it means that the sprinkler irrigation intensity is too large, and the working pressure should be reduced or the nozzle with smaller diameter should be replaced in time.

IV. Maintenance after use

1. After sprinkler irrigation, the machine, pump and sprinkler should be scrubbed clean, the lubrication parts should be lubricated on time, and the water in the pump and pipe should be put out every time in winter to prevent frost cracking. The maintenance of the machine and pump should be carried out in accordance with the instructions.

two。 When the unit is out of use for a long time, the water stored in the pump must be released. Remove the water pump and sprinkler, wipe off the water stains, oil and assemble the package, and store it in a dry place. If there are damaged parts, they should be repaired or replaced in time.

3. The water in the pipe should be emptied, and the anti-rust layer should be repaired. The moving hose should be washed clean and fully dried, and the plastic pipe should be protected from exposure and stored in a ventilated and dry warehouse.
