Intelligent truss type reel sprinkler

Abstract

The invention discloses an intelligent truss type reel sprinkler. The sprinkler comprises a rack, a reel, a PE pipe, a reel drive gearbox, a truss type sprinkler wagon and an electric control device;a swinging truss of the truss type sprinkler wagon comprises a middle truss body, a left truss body and a right truss body, wherein the left truss body and the right truss body are symmetrically disposed on the left and right sides of the middle truss body; the left truss body and the right truss body both include a swinging truss basic node and multiple retractable truss nodes, wherein each swinging truss basic node can be controlled to automatically swing by a basic node swinging and rotation drive mechanism, and the retractable truss nodes can be controlled to extend or retract automatically by a driving gear rolling drive mechanism and a lower water pipe end lifting control mechanism and retractably inserted in sequence. The intelligent truss type reel sprinkler can achieve reduction of the overall weight of the truss under the premise of ensuring the overall strength of the truss, thereby reducing power consumption, achieving rapid and automatic unfolding and storage of the truss,and thus realizing rapid transfer operation. The sprinkler can be intelligently controlled according to sprinkler irrigation needs of crops and is especially applicable to sprinkler irrigation operation of large farms.

Description

technical field [0001] The invention relates to a reel sprinkler irrigation machine, in particular to a truss type reel sprinkler irrigation machine with intelligent operation, belonging 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 sp...

AI Technical Summary

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
