A method of using a truss type sprinkler truck that can be automatically expanded or folded

Abstract

The invention discloses a method for using a truss-type sprinkler truck that can be automatically expanded or folded. Both the left truss and the right truss of the automatically expandable or foldable truss-type sprinkler vehicle include a swinging truss base section and a folding truss section. And a connecting pipe, the inner end of the swing truss base section is hingedly installed on the middle truss, the inner end of the folded truss section is hingedly installed on the outer end of the swing truss base section, and one end of the connecting pipe is hingedly connected to the main support chassis , the other end is hingedly connected to the water delivery pipe under the folding joint, the entire section of the water delivery pipe under the base section, part of the water delivery pipe under the folding section, the entire section of the connecting pipe, and the hinge point of the connecting pipe and the hinge point of the water delivery pipe under the base section The virtual connecting rods together form a four-bar linkage. The present invention can realize the fast unfolding and storage of the truss, and then realize the quick transition operation of the truss type reel sprinkler, and is especially suitable for the small truss type reel sprinkler.

Description

technical field [0001] The invention relates to a method for using a sprinkler truck, in particular to a method for using 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 user...

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
