Multifunctional reel-type sprinkling machine

Abstract

Provided is a multifunctional reel-type sprinkling machine. On the basis of an original structure, a vehicle return stop linkage device and an automatic water turbine speed-regulating device are additionally arranged. A water spraying traveling crane further comprises a sleeve, an idler wheel and an idler wheel installation frame, wherein the idler wheel installation frame is installed on a metal connection pipe through a clamping hoop. The vehicle return stop linkage device comprises a closing frame arranged at the front end of a machine frame, a closing frame zipper, a locking rod, an adjusting screw rod, a connection rod, a tension spring, a brake pull rod, a swinging arm assembly and a brake connection board, wherein the swinging arm assembly and the brake connection board are arranged on a gearbox. The automatic water turbine speed-regulating device comprises an induction frame and a speed-regulating link rod. According to the sprinkling machine, after the water spraying traveling crane returns back, automatic braking can be achieved through a reel, automatic speed regulation of a water turbine is achieved, and the water spraying traveling crane retreats at a constant speed. The clamping hoop on the water spraying traveling crane can replace an iron wire to bundle a PE hose, bundling can be conveniently achieved, and meanwhile the PE hose is protected against damage; a pipe rack can rotate freely and accordingly action force of the PE hose cannot be forcibly exerted on a ball screw assembly.

Description

technical field [0001] The invention relates to an agricultural irrigation equipment, in particular to a multifunctional reel type sprinkler irrigation machine. Background technique [0002] In the field of agricultural irrigation, the reel sprinkler is an important sprinkler irrigation equipment. Its production greatly facilitates the irrigation of farmland, saves a lot of labor, and improves irrigation efficiency. The current reel sprinkler includes water spray Driving, frame and reel set on the frame, water turbine, gearbox, pipe arrangement and travel wheels, the gearbox is equipped with a manual shift lever and brake wheels, the manual shift lever can adjust the speed of the reel, brake A brake band is arranged on the wheel, and the brake band is operated by a brake lever to brake. The water turbine is provided with a manual speed regulating device connected to the regulating valve. The manual speed regulating device includes a threaded rod and a speed regulating knob...

AI Technical Summary

Problems solved by technology

[0003] 1. During the traveling process of the water spray vehicle, the bottom of the metal connecting pipe is a fulcrum of the water spray vehicle, so the force is relatively large, and the PE hose is connected to the bottom of the metal connecting pipe, which is easy to cause wear of the PE hose; and , When the PE hose is connected with the metal connecting pipe, it is basically bound with iron wire. It is very troublesome to install and disassemble each time. If it is tied with iron wire for a long time, it is easy to damage the connection part of the water pipe.

[0004] 2. When the water spray truck is pulled back, it is necessary to manually operate the manual shift lever to stop the reel, which is not only troublesome to operate, but also needs to manually judge the distance between the water spray truck and the sprinkler during the return process of the water spray truck. If the judgment is not good, the sprinkler will collide with the sprinkler

[0005] 3. During the return process of the water spray vehicle, because the diameter of the reel is changing, but the manual speed control device of the water turbine can only set the water speed to a fixed value, so the speed of the reel is constant, and the return speed of the water spray vehicle is easy. Gradually decreasing, not only causing uneven irrigation, but also wasting water resources

[0006] 4. The PE hose will directly contact the inner side of the pipe rack, and when the PE hose moves, it will rub against the inner side of the pipe rack and damage the surface of the PE hose; moreover, the PE hose will be in the pipe rack during the rolling process. Shaking back and forth, the impact force of the PE hose on the pipe rack directly acts on the sleeve, causing damage to the ball screw assembly; the lower part of the pipe rack is directly placed in the gap between the two steel pipes, and the pipe rack is in the When sliding in the gap, the frictional resistance is relatively large, which will also cause damage to the ball screw
