A method of using a truss-type sprinkler truck with a pipe joint structure

Abstract

The invention discloses a use method of a pipe joint structure truss sprinkler car. The pipe joint structure truss type sprinkler car comprises a swing truss which comprises a left truss, a middle truss and a right truss, and the left truss and the right truss each comprise a swing truss base section, multiple folding truss sections and a tail section water delivery pipe which are arranged in sequence from inside to outside; the swing truss base sections and the folding truss sections are each of a frame structure, and a hinged connection mechanism and a swing angle limiting mechanism are hinged to the two ends of an upper support pipe; communication transition joins are arranged at the two ends of a lower water delivery pipe; by means of a controller, a swing driving mechanism is controlled to achieve unfolding or storage operation, after the swing driving mechanism is completely unfolded, irrigation water is input into a main pipeline, the lower water delivery pipe and the tail section water delivery pipes to form a through water transporting channel, and after storage, the communication transition joint is in a cut-off state. Accordingly, a truss can be rapidly unfolded and stored, thus rapid transition operation of a truss type reel sprinkling machine is achieved, and the car is especially suitable for the sprinkler irrigation operation of large farms.

Description

technical field [0001] The invention relates to a method for using a truss type sprinkler truck, in particular to a method for using a pipe joint structure truss type sprinkler truck suitable for a reel sprinkler irrigation machine, 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 mee...

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

On the one hand, since the sprinkler truck usually has a two-wheeled structure with retraction traction from the PE pipe, and the retraction traction of the sprinkler truck is affected by the flatness of the ground, the traction force is uneven, so the large-volume and heavy-weight truss will make the entire sprinkler truck The weight increases and the stability decreases, which not only requires greater traction and increased power consumption, but also easily causes excessive crushing of crops when walking; on the other hand, in order to facilitate transportation, the existing truss-type reel sprinkler Most of the trusses of the wire-drawing frame structure are multi-section dismantling structures. However, the disassembly and assembly of the trusses and sprinkler irrigation pipes of the wire-drawing frame structure is not only labor-intensive, but also the disassembly efficiency is low, and it is impossible to realize the rapid operation of the truss-type reel sprinkler irrigation. Transition operation; on the other hand, the sprinkling height of the existing truss-type reel sprinkler is usually adjusted artificially according to the height of the crops before the sprinkling operation, and the height of the truss from the ground cannot be adjusted during the sprinkling process. In the case of planting crops of different heights in the area, automatic adjustment cannot be realized, which will affect the sprinkler irrigation effect
