Self-walking type reel sprinkler capable of changing weight of sprinkler wagon

Abstract

The invention discloses a self-walking type reel sprinkler capable of changing the weight of a sprinkler wagon. The sprinkler comprises an underframe (1), a reel (2), a PE pipe (3), a water turbine box (4), a reel drive gearbox (5) and the sprinkler wagon (6); the sprinkler wagon comprises a power source (63), a sprinkler wagon drive gearbox (64), a control valve group (67) and a water tank (68);an input end of the control valve group (67) is connected with an output end of the PE pipe (3), one path of an output end of the control valve group (67) is connected with a spray nozzle (66) througha pipeline, and the other path of the output end of the control valve group (67) is connected with the water tank (68); a stop valve V (681) is arranged on the lower portion of the water tank (68). According to the self-walking type reel sprinkler capable of changing the weight of the sprinkler wagon, the weight of the sprinkler wagon can be changed by changing the water storage capacity of the water tank, and the rewinding resistance of the PE pipe can be lowered in the PE pipe rewinding process on the premise that the sprinkler wagon can generate enough road holding capacity to pull the PEpipe to walk by itself.

Description

technical field [0001] The invention relates to a reel sprinkler irrigation machine, in particular to a self-propelled reel sprinkler irrigation machine with a sprinkler truck capable of changing its own weight, and belongs to the technical field of sprinkler irrigation equipment. Background technique [0002] Sprinkler irrigation is an irrigation method that uses special equipment such as nozzles to spray pressurized water into the air to form water droplets that fall to the ground sprinkler surface and crop surface. [0003] The reel sprinkler irrigation machine is a relatively common type of sprinkler irrigation machine. It is an irrigation machine that winds the traction PE pipe on the winch, uses the sprinkler pressure water to drive the gearbox to drive the winch to rotate, and pulls the sprinkler car to move and spray automatically. It can be changed The self-propelled reel sprinkler irrigation machine with the weight of the sprinkler truck can irrigate a large area o...

Problems solved by technology

[0005] The sprinkler cart of the reel sprinkler irrigation machine usually does not have power. When working, it is usually necessary to use tractors or winches and other traction equipment to drag the PE water delivery pipe wound on the reel and the sprinkler truck connected to the PE water delivery pipe to the preset position. The sprinkler irrigation site, and then turn on the pressure water to drive the water turbine to provide the rewinding power of the PE pipe to realize the automatic recovery of the PE pipe. This traditional reel sprinkler that requires additional traction equipment requires additional power consumption and complicated operation.

[0006] Therefore, there are reel sprinkler irrigation machines with self-propelled sprinkler carts in the prior art. Usually, the power source is directly added to the sprinkler cart to realize the self-propelled sprinkler cart, but if the self-propelled sprinkler cart is realized, its own weight must reach a certain level The quality of the nozzle can only achieve enough grip to pull the PE pipe, otherwise the nozzle truck can only slip on the spot and cannot achieve traction. However, the heavy weight of the nozzle truck also becomes the obstacle for PE pipe rewinding when the PE pipe is automatically rewound. Resistance, and the self-propelled sprinkler vehicle with power source in the prior art can only drive the sprinkler vehicle, and its function is relatively single
