An automatic irrigation device for agricultural planting

Abstract

The invention provides an automatic irrigation device for agricultural planting, which belongs to the technical field of agricultural irrigation, and includes a walking device and a water supply system. The walking device is connected with a mounting seat, and the mounting seat is connected with a movable arm assembly and a control system used in cooperation with each other. Assemblies, a number of nozzle parts are arranged on the movable boom assembly, the movable boom assembly includes a number of arm rods and limit rotation connectors, the control assembly is used to control the expansion and retraction of the movable boom assembly, and when the movable boom assembly is folded, the straight line The corner points are connected together successively to form a regular polygon, and the movable boom assembly is linear when unfolded. The automatic irrigation device for agricultural planting, through the design of the structure of the movable extension arm component, effectively improves the convenience of disassembly and use of the sprinkler irrigation device on the basis of ensuring the coverage of the spraying effect, and can automatically complete the collection and use of residual water. , avoiding the waste of water resources, improving the service life of the water supply hose, and the overall structure is relatively simple.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to an automatic irrigation device for agricultural planting. Background technique [0002] The irrigation methods used in agricultural planting mainly include watering, sprinkler irrigation and drip irrigation. Among them, irrigation consumes a large amount of water resources and has a low utilization rate of water resources. It has been gradually replaced by sprinkler irrigation and drip irrigation. The water replenishment speed of drip irrigation is slower but the accuracy is higher , it is more suitable for indoor fine planting, and sprinkler irrigation has a high comprehensive utilization rate in terms of water replenishment speed, water resource utilization rate and water replenishment accuracy. It is very suitable for the planting of large-scale outdoor crops and is currently widely used. In order to improve the flexibility of sprinkler irrigation, mobile sprin...

AI Technical Summary

Problems solved by technology

[0003] The existing mobile sprinkler irrigation device mainly uses the walking device to drive the nozzle to move and spray water on the crops. In order to increase the spraying range and improve the efficiency of sprinkler irrigation, a horizontal display frame is usually set on the walking device, and the nozzles are evenly arranged on the display frame. In order to increase the coverage of spraying and improve the efficiency of sprinkler irrigation, but its disadvantages are that the display rack is large in size, troublesome to disassemble and assemble, and the convenience of use and storage is very low.

[0004] The publication number is CN109287448A. The Chinese invention patent discloses an intelligent truss-type reel sprinkler. The patent increases the scope of spraying coverage through the left truss and the right truss, and uses the left and right trusses to fold back and store them in a wing-like structure to achieve rapid irrigation. Unfolding and storage, but its overall structure is complicated. During the storage and expansion process, the water delivery pipe needs to be separated, disconnected or connected, which greatly reduces the stability of sprinkler irrigation.

[0005] Secondly, some mobile sprinkler irrigation devices fold the water pipes synchronously when storing the folding display racks, but it is easy to cause wear and tear on the water pipes, and because there is usually residual water in the water pipes after the irrigation operation is completed, there is no effective way to fold the display racks. Drainage measures, the remaining water will stay in the pipeline and reduce the service life of the pipeline
