A cam type sprinkler

Abstract

The invention discloses a cam type jet-irrigating machine and belongs to the technical field of agricultural water-saving irrigation. The cam type jet-irrigating machine comprises a rack, a water pump assembly, a reel assembly, a hard water pipe I, a cam spray head, a storage battery, a drive motor I, a drive motor II, a speed changing box I, a speed changing box II, caterpillar bands, drive crawler wheels, driven crawler wheels, a reel water pipe and a balance device. By means of the cam type spray head which is specially designed, the original circular jet-irrigating area can be converted into a square jet-irrigating area, overlapping of jet-irrigating areas is avoided, jet-irrigating dead corners of a square land can be eliminated, water can be saved, and the jet-irrigating uniformity can be improved. The automatic balance device can solve the problem that in rugged terrain, the shape of the jet-irrigating face changes. A crawler type vehicle serves as a carrier of the jet-irrigating machine, and the jet-irrigating machine can adapt to various complex terrains; the two drive motors serve as a walking power device, the jet-irrigating machine can be more easily and effectively controlled to swerve, automation can be achieved better through motor drive, and the labor intensity of workers can be lowered.

Description

technical field [0001] The invention relates to a cam-type sprinkler irrigation machine, in particular to a cam-type sprinkler irrigation machine with a square irrigation surface, belonging to the technical field of agricultural water-saving irrigation. Background technique [0002] Sprinkler irrigation is an irrigation method that uses special equipment such as sprinklers to spray pressurized water into the air, forming water droplets that fall to the ground sprinkler surface and crop surface. This irrigation method has the advantages of water saving, labor saving, and strong terrain adaptability. Compared with drip irrigation, due to the higher working pressure, it has a faster flow rate and a larger outflow, which reduces the possibility of clogging. A single nozzle can spray a larger area, so the material used per mu is less than that of drip irrigation, saving costs. Therefore, it has broad application prospects. [0003] In recent years, a lot of equipment has been d...

Problems solved by technology

[0003] In recent years, a lot of equipment has been developed around water-saving sprinkler irrigation and small and medium-sized sprinkler irrigation machines, such as the authorized invention patent of a spray gun with adjustable elevation angle (201320732877.0), the authorized invention patent of a wind-resistant sprinkler irrigation water-saving nozzle robot (201020582747. X), a public invention patent for establishing a three-dimensional dynamic water distribution model for variable speed nozzles (201510543947.1), light winch type sprinkler irrigation machine (201510537883.4), etc. These devices have a good effect on improving the efficiency of sprinkler irrigation, but these sprinkler irrigation machines Most of the sprinkling irrigation surfaces are circular, and the water volume overlap and leakage are serious. In addition, the sprinkler is greatly affected by the terrain during operation, resulting in no significant improvement in the uniformity of sprinkling irrigation. One of the sprinkling irrigation guns with adjustable elevation angle According to the wind speed when the sprinkler is working, adjusting the pitch angle of the sprinkler head through the height adjustment device improves the adaptability of the sprinkler spray gun to the environment. Although the wind resistance and other performances are improved, it cannot solve the problems of overlapping irrigation surfaces, irrigation dead ends and waste; A wind-resistant sprinkler irrigation water-saving sprinkler robot reduces the impact of wind on the accuracy of sprinkler irrigation by adjusting the angle of the sprinkler head and the water pressure, but the sprinkler head still uses ordinary sprinklers, which are no different from ordinary sprinklers in the absence of wind, so there are also some shortcomings of traditional sprinklers; A method for establishing a three-dimensional dynamic water distribution model of variable speed nozzles. By studying the characteristics of various nozzles and adjusting the types of nozzles and the distance between nozzles to improve uniformity, this method is time-consuming and laborious to improve uniformity. The problem of surface overlap is not conducive to water saving; the light winch sprinkler uses the most commonly used wheeled trolley as the carrier, which has high requirements on the terrain and is not conducive to walking on rough roads, and the scope of application is relatively small
