Description

Drip irrigation zone laying brake device Technical Field The utility model belongs to the technical field of drip irrigation tape laying, and particularly relates to a drip irrigation tape laying brake device. Background With the rapid development of modern agriculture, the drip irrigation technology is widely applied to fields of field crops, fruit and vegetable planting and the like due to the advantages of water saving, fertilizer saving, crop yield improvement and the like. As an important component of the drip irrigation system, the paving quality of the drip irrigation tape directly influences the irrigation uniformity and the water supply stability of the root system of crops. At present, a drip tape laying device mostly adopts an operation mode of tractor traction, and a drip tape is released along with a roller and buried in an operation path. Although the mechanical operation mode obviously improves the laying efficiency and reduces the manual operation intensity, the mechanical operation mode also exposes a plurality of technical problems to be solved in actual construction. In the field operation process, the tractor often faces complicated and changeable terrains and operation environments, and sudden conditions are unavoidable, such as emergency braking, obstacle avoidance, unstable running speed caused by soft soil, and the like. When the tractor is braked suddenly or suddenly, the connected drip irrigation belt roller cannot be braked synchronously and accurately with the tractor due to the inertia effect, so that the roller is excessively rotated. The continuous rotation caused by inertia causes the drip irrigation tape being laid to relax, the paying-off speed is asynchronous with the vehicle advancing speed, and adverse effects such as accumulation, winding or bending of the drip irrigation tape are finally caused. These adverse consequences not only lead to a reduced precision of the laying of the drip tape, affecting the irrigation effect, but also may cause damage to the drip tape, reducing the efficiency of agricultural production. At present, most drip tape laying devices only rely on damping of a mechanical structure or simple tensioning mechanism to adjust, and effective dynamic control is not carried out on a roller in an inertial motion state, so that the problems of loosening and uneven paying-off caused by inertia are difficult to fundamentally solve. The technical short plate limits the automation and fine laying operation level of the drip irrigation tape and becomes one of the bottlenecks for restricting the development of intelligent agricultural equipment.
