There are many classification methods for sprinkling irrigation systems, such as according to the spraying characteristics, there are fixed spraying type and row spraying type. The fixed spraying type is divided into pipeline type and unit type. The row spraying type is divided into center shaft type, translation type and reel type. Among them, the reel sprinkler is the best in irrigation machinery, which can provide economic and reliable service and is the best choice for irrigating field crops. The reel sprinkler refers to a sprinkler that uses a hose to supply water, winds the hose with a reel, and pulls a long-range spray head, so that the spray head moves along the operation route during the sprinkling process. The spray head trolley frame can self-walk and self-stop during spraying, which is easy to manage and operate, saves labor and has low labor intensity. It is commonly used for watering of vegetables, flowers, rice, fruit trees, grapes, hops or seaweed cultivation and forestry.

[0003] According to the Chinese patent with the publication number "CN113142028B", a bottomless reel sprinkler is disclosed, which comprises a reel support frame, a reel, a spray head vehicle, a reel support frame rotating device and a reel support frame lifting device. The reel support frame lifting device comprises a swing lifting assembly symmetrically installed on the left and right end faces of the reel support frame. The end of the last telescopic joint of the front swing telescopic beam and the rear swing telescopic beam is also fixedly provided with a telescopic support leg, and the telescopic support leg comprises at least one telescopic joint. The present bottomless reel sprinkler can realize easy self-loading or unloading under the premise of greatly reducing the overall gravity center of the reel sprinkler, and can avoid the problem of excessive crushing of crops at the field head. The existing reel sprinkler has the problem that when the spray head trolley frame moves away from the pipe disc trolley frame at a speed that is too fast, the pipe disc cannot keep up with the speed, causing the water pipe to be pulled, affecting the use of the reel sprinkler. Therefore, a self-adaptive speed regulating device for reel sprinkler is proposed to solve the above problems. SUMMARY

When the moving speed of the nozzle trolley is greater than the pipe-laying speed of the pipe-laying disc, the water pipe will change from a slack state to a taut state. At this time, the water pipe will be straightened, causing the water pipe to lift the lifting plate upward. The sensing module then approaches the distance sensor, which transmits a signal to the controller in the drive box, causing the drive motor to increase the pipe-laying speed of the pipe-laying disc, thus achieving automatic speed adjustment and avoiding the problem of pipe pulling caused by slow pipe-laying speed.

[0007] The angle adjustment mechanism includes a first bearing and a rotating column. The rotating column is fixedly installed on the inner wall of the inner ring of the first bearing.

[0022] 2. The self-adaptive speed regulating device of the reel type sprinkler, through the cooperation between the first bearing, the rotating column, the connecting frame, the guide opening, the adjusting seat, the second bearing, the roller, the limiting seat and the connecting shaft, when the nozzle trolley frame is offset from the pipe releasing disc during movement, the water pipe will contact the rotating roller, so that the base moves along the guide opening, and the base is deflected left and right relative to the adjusting seat, so as to achieve self-adaptive adjustment, facilitate pipe releasing, and further improve the flexibility of the device for vegetable planting sprinkling.

[0023] 3、The reel type sprinkler self-adaptive speed regulating device, through the cooperation operation between the device frame, the bidirectional screw rod, the rotating handle, the first clamping plate, the second clamping plate, the rubber sheet, the rotating shaft and the rubber wheel, when the reel type sprinkler is not used or transported, the staff can drive the bidirectional screw rod to rotate by rotating the rotating handle, so that the first clamping plate and the second clamping plate clamp and fix the rubber wheel, so that the rotating shaft cannot rotate, so that the pipe disc is locked and cannot rotate, avoiding the problem that the pipe disc is rotated by external force to cause the water pipe to be tangled, facilitating locking the pipe disc after the pipe is collected after the vegetable planting is sprinkled.

[0024] 4、The reel type sprinkler self-adaptive speed regulating device, when the water pipe is stretched too fast, the water pipe will be in a rising and straightening state below the lifting plate, and the lifting plate will exert a buffering force on the water pipe through the lifting plate under the action of the spring, thereby avoiding the problem that the water pipe is damaged due to the too large pulling force in the state of too fast stretching, and improving the service life of the water pipe.

[0025] 5、The reel type sprinkler self-adaptive speed regulating device, when the pipe disc driven by the motor has a too fast pipe releasing speed, the staff can also rotate the rotating handle to clamp the rubber wheel with the first clamping plate and the second clamping plate, so as to increase the resistance to the rotation of the pipe disc, thereby achieving the purpose of preventing the pipe disc from having a too fast pipe releasing or collecting speed under the driving of the motor.

[0026] 6、The reel type sprinkler self-adaptive speed regulating device, when the pipe needs to be collected, the staff can place the pipe section in the cleaning frame between the two push rods, then rotate the handle to lower the adjusting plate, so that the upper and lower brush plates contact the outer wall of the water pipe, and then start the servo motor to drive the moving seat to reciprocate, at this time the water pipe will be cleaned by the two brush plates during the winding process, and at the same time, due to the reciprocating pushing of the push rod, the water pipe will be wound around the pipe disc at both ends, avoiding the problem that the water pipe is wound in the same place, causing the pipe to be stuck and wound in the later stage.

[0027] 7、The reel type sprinkler self-adaptive speed regulating device, when the pipe disc is driven by the motor, the two plum blossom rollers can rotate following the pipe releasing process, the two plum blossom rollers can crush the ice blocks in the water pipe by rotating and extruding, and the two driven frames can also drive the two plum blossom rollers to slide in the horizontal direction following the water pipe, so that the two plum blossom rollers can still maintain the ice crushing effect during the movement of the water pipe, after the ice blocks in the water pipe are crushed, the possibility of pipe blockage is reduced, and the crushed ice can be discharged from the water pipe faster, avoiding the risk of pipe cracking when the water pipe is used in cold weather due to a small amount of water remaining in the water pipe 7 after the last use, which causes pipe blockage due to ice formation.
