Truss type spray nozzle vehicle capable of being automatically unfolded or folded

Abstract

The invention discloses a truss type spray nozzle vehicle capable of being automatically unfolded or folded. A left truss and a right truss each comprise a swing truss base joint, a folding truss joint and a connecting pipe, wherein the inner side end of the swing truss base joint is hinged to a middle truss, the inner side end of the folding truss joint is hinged to the outer side end of the swing truss base joint, one end of the connecting pipe is hinged to a main supporting base frame, the other end of the connecting pipe is hinged to a water conveying pipe below the folding joint, and virtual connecting rods between hinge points of a water conveying pipe below the base joint, hinge points of the connecting pipe and the whole connecting pipe section, the water conveying pipe part belowthe folding joint and the whole water conveying pipe section below the base joint jointly form a four-connecting-rod mechanism. The whole weight of the truss can be lowered on the premise of ensuringthe overall intensity of the truss, then, power consumption is lowered, meanwhile, the truss can be rapidly unfolded and stored, the rapid scene changing operation of a truss type reel sprinkler is achieved, and the vehicle is particularly applicable to a small truss type reel sprinkler.

Description

technical field [0001] The invention relates to a sprinkler truck, in particular to a truss-type sprinkler truck that can be automatically unfolded or folded, 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, forming water droplets that fall to the ground sprinkler surface and crop surface. [0003] Reel sprinkler irrigation machine is a relatively common type of row sprinkler irrigation machine. It is an irrigation machine that winds the traction PE pipe on the winch, uses the gearbox to drive the winch to rotate, and pulls the sprinkler car to automatically move and spray. The sprinkler irrigation machine can irrigate a large area of ​​farmland, and can also control the amount of water sprayed according to the nozzle to meet the different requirements of users for the amount of sprinkler irrigati...

AI Technical Summary

Problems solved by technology

[0005] However, the total length of the truss of the existing small truss type reel sprinkler is usually 10 to 20 meters. In order to ensure the overall strength of the longer truss, a frame structure with steel wire pulling and a triangular or rectangular longitudinal section is often used. The overall weight of the frame structure is relatively large, and the truss of the frame structure is usually supported and fixed on the sprinkler truck by a large-volume and heavy-weight bracket. Since the sprinkler truck usually has a two-wheeled structure whose retraction traction comes from PE pipes, and the retraction traction of the sprinkler truck Affected by the flatness of the ground, the traction force is uneven. Therefore, the large-volume and heavy-weight truss will increase the weight of the sprinkler truck and reduce the stability. It not only requires greater traction force and power consumption, but also easily causes Excessive crushing of crops; in addition, in order to facilitate transportation, the trusses of the wire-drawing frame structure of the existing truss-type reel sprinkler irrigation machine are mostly disassembled structures, but the truss of the wire-drawing frame structure and the sprinkling irrigation The pipeline is not only labor-intensive, but also has low disassembly efficiency, which makes it impossible to realize the quick transition operation of the truss-type reel sprinkler
