Truss type sprinkler wagon

Abstract

The invention discloses a truss type sprinkler wagon. A swing truss comprises a middle truss, a left truss and a right truss, wherein the left truss and the right truss are bilaterally symmetrically arranged on the left side and the right side of the middle truss; the left truss and the right truss both comprise a swing truss base section, multiple telescopic truss sections and a tail section water conveying pipe; a base section pipe end of the swing truss base section and the outer end of the middle truss are hinged and installed through a vertical hinge shaft, and the telescopic truss sections are in telescopic insertion connection in sequence. According to the truss type sprinkler wagon, the swing truss base section and the telescopic truss sections of a frame sliding structure are used, and downward bent torque is generated by self gravity, so that end faces of lower water conveying pipes are in pressed sealing, and on the premise that the overall strength of the truss is ensured,the overall weight of the truss is reduced and then the power consumption is reduced. Meanwhile, rapid unfolding and storage of the truss can be realized, rapid field transferring operation can be conducted, and the sprinkler wagon is particularly suitable for a truss type reel sprinkling irrigation machine.

Description

technical field [0001] The invention relates to a sprinkler truck, in particular to a truss type sprinkler truck, which 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 irrigation water. It is the sprinkler irrigation eq...

Problems solved by technology

[0005] However, the total length of the truss of the existing small-scale truss-type reel sprinkler is usually 10-20 meters, the total length of the truss of the medium-sized truss-type reel sprinkler is usually 20-30 meters, and the large-scale truss-type reel sprinkler The total length of the truss is usually 30 to 45 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, but the overall weight of the frame structure is relatively large, and the frame structure The truss is usually supported and fixed on the sprinkler truck by a large-volume and heavy-weight bracket. Since the sprinkler truck is usually a two-wheeled structure whose retraction traction comes from PE pipes, and the retraction traction of the sprinkler truck is affected by the flatness of the ground, the traction force is uneven. Therefore, a large-volume and heavy-weight truss will increase the weight and reduce the stability of the sprinkler truck, which not only requires greater traction and increased power consumption, but also easily causes excessive crushing of crops when walking; For transportation, the trusses of the wire-drawing frame structure of the existing truss-type reel sprinkler irrigation machine are mostly multi-section disassembly structures, but the disassembly and assembly of the trusses and sprinkler irrigation pipes of the wire-drawing frame structure is not only labor-intensive, but also has low disassembly efficiency. , it is impossible to realize the fast transition operation of the truss type reel sprinkler
