Description
Technical Field
The invention relates to a truss type spray head vehicle, in particular to a truss type spray head vehicle with a foldable pipe joint structure, which is suitable for a reel type spray irrigation machine, and belongs to the technical field of spray irrigation equipment.
Background
The sprinkling irrigation is a method of sprinkling irrigation with pressure water to the air by using special equipment such as a spray head, etc., so as to form water drops falling on the ground sprinkling irrigation surface and the surface of crops.
The reel type sprinkler is a common one in a row-spraying sprinkler, is an irrigation machine which winds a traction PE pipe on a winch, drives the winch to rotate by utilizing a gearbox, and automatically moves and sprays a traction spray head car, can irrigate a large-area farmland, can control the water spraying amount according to a spray head, meets different requirements of a user on the water spraying amount, and is a normally selected sprinkling irrigation device for farmland water-saving irrigation. The reel type sprinkler generally mainly comprises a bottom frame, reels, PE pipes, a gearbox and a sprinkler head vehicle, wherein the gearbox drives a chain to drive to generate larger torque force to drive a winch to rotate after the speed of the gearbox is reduced, so that the PE pipes are automatically recovered, meanwhile, high-pressure water flows through the PE pipes to be directly sent to the sprinkler heads of the sprinkler head vehicle, the sprinkler heads evenly spray high-pressure water flow to the upper air of crops and scatter into fine water drops to evenly fall, and the sprinkler head is enabled to carry out sprinkling operation along with the movement of the PE pipes without intermittence.
The truss type reel sprinkler is a reel sprinkler which is formed by installing trusses on a spray head vehicle and replacing spray guns by a plurality of spray heads arranged on the trusses, can realize lower sprinkling irrigation height and sprinkling irrigation close to crops, has relatively lower sprinkling irrigation water pressure and relatively lower energy consumption when the truss type reel sprinkler works, has smaller beating strength to crops and soil when sprinkling irrigation water, and has smaller sprinkling water drop, relatively higher water distribution uniformity and smaller influence by wind force when sprinkling irrigation water to crops in short fields such as wheat, soybean and vegetables.
However, the total truss length of the existing small-sized truss type reel sprinkler is usually 10-20 m, the total truss length of the medium-sized truss type reel sprinkler is usually 20-30 m, the total truss length of the large-sized truss type reel sprinkler is usually 30-45 m, in order to ensure the overall strength of a longer truss, a frame structure with a triangular or rectangular longitudinal section and pulled by steel wires is usually adopted, but the overall weight of the frame structure is large, and the truss of the frame structure is usually supported and fixed on a sprinkler head vehicle through a large-size and heavy-weight bracket. On the one hand, the spray head vehicle is usually of a two-wheel structure with the back traction force from the PE pipe, and the back traction force of the spray head vehicle is influenced by the flatness of the ground, so that the truss with large volume and large weight can increase the weight of the whole spray head vehicle, reduce the stability, not only needs larger traction force and power consumption, but also is easy to cause excessive rolling of crops during walking; on the other hand, in order to facilitate transportation, the trusses of the steel wire traction frame structure of the existing truss type reel sprinkler are mostly of multi-section dismounting structures, however, the trusses and sprinkling pipelines of the dismounting steel wire traction frame structure are high in labor intensity and low in dismounting efficiency, and quick transfer operation of the truss type reel sprinkler cannot be realized; in yet another aspect, the height of the truss distance from the ground is manually adjusted before the sprinkling operation according to the height of the crops in the existing truss type reel sprinkling machine, but the sprinkling process cannot be adjusted, so that the automatic adjustment cannot be realized according to the condition that crops with different heights are planted in different areas of a farmland, and then the sprinkling effect can be influenced.
