Description

Truss type spray head vehicle with foldable pipe joint structure

Technical Field

The utility model relates to a truss-like shower nozzle car specifically is a collapsible pipe joint structure truss-like shower nozzle car suitable for reel formula sprinkling irrigation machine, belongs to sprinkling irrigation equipment and equips technical field.

Background

The spray irrigation is an irrigation method that the pressure water is sprayed into the air by using special equipment such as a spray nozzle and the like to form water drops which fall on the ground spray irrigation surface and the crop surface.

The reel formula sprinkling irrigation machine is the more common one in the formula sprinkling irrigation machine of row, will pull the PE pipe winding on the capstan winch, utilize the gearbox to drive the capstan winch rotatory to pull the irrigation machinery of shower nozzle car automatically move and spraying, the reel formula sprinkling irrigation machine can irrigate the farmland of large tracts of land, also can be according to the size of shower nozzle control water spray, in order to satisfy the different requirements of user to the sprinkling irrigation water yield, is the sprinkling irrigation equipment that farmland water-saving irrigation chooseed for use usually. The reel type sprinkling machine generally mainly comprises an underframe, a reel, a PE pipe, a gearbox and a sprayer vehicle, wherein the gearbox is driven to decelerate to drive a chain to generate a large torque force to drive the winch to rotate so as to realize the automatic recovery of the PE pipe, meanwhile, high-pressure water flows through the PE pipe and is directly conveyed to the sprayer of the sprayer vehicle, the sprayer uniformly sprays high-pressure water flow to the upper part of crops, the high-pressure water flow is scattered into fine water drops to uniformly fall, and the spraying operation is carried out non-intermittently along with the movement of the PE pipe.

Truss-like reel sprinkling irrigation machine is installed the truss on the shower nozzle car, and replace the reel sprinkling irrigation machine that the spray gun accomplished the sprinkling irrigation operation through installing a plurality of shower nozzles on the truss, truss-like reel sprinkling irrigation machine can realize lower sprinkling irrigation height for traditional spray gun formula reel sprinkling irrigation machine, press close to the crop and spray irrigation, and truss-like reel sprinkling irrigation machine during operation sprinkling irrigation water pressure is lower relatively, energy resource consumption is less relatively, it is less to the striking intensity of crops and soil to spout simultaneously watering, in addition, the sprinkling water of a plurality of shower nozzles drips little, the moisture distribution degree of consistency is high relatively, it is little to receive the wind-force influence, consequently to wheat, soybean, the sprinkling irrigation of low field crops such as vegetables has better suitability.
