Description

Technical Field

[0001] The present invention relates to the technical field of drip irrigation, and specifically to a precise drip irrigation device with an automatic adjustment function. Background Art

[0002] Drip irrigation technology is an efficient water-saving agricultural irrigation technology. By precisely supplying water near the roots of crops, it reduces water resource waste and improves irrigation efficiency. Compared with the traditional flood irrigation method, the drip irrigation system can significantly reduce evaporation and leakage losses, and the water utilization rate can be as high as over 95%. It is especially suitable for areas with water shortages. In recent years, drip irrigation technology has been widely applied in arid and semi-arid regions, not only significantly increasing crop yields and farmers' incomes, but also greatly reducing the labor intensity of irrigation and optimizing agricultural production management. In addition, drip irrigation technology can improve soil structure, reduce soil erosion, and effectively control the occurrence of pests and diseases. Through scientific integrated water and fertilizer management, drip irrigation technology plays an important role in promoting the sustainable development of agriculture and ensuring food security.

[0003] Most existing drip irrigation systems use capillary tubes as drip irrigation devices. Due to the influence of regional climate, the capillary tubes are extremely prone to cracking and cannot be monitored in real time, resulting in a large amount of irrigation water loss in the cracked tube parts. Moreover, the capillary tubes can only wet the cotton area around the drip holes, thus causing uneven humidity in the entire cotton field, and further leading to insufficient water supply for some planted crops, affecting the overall quality. Summary of the Invention

[0015] Working principle: When the device needs to be used, first pull the damper to rotate inside the first hinge block, and then rotate the mounting plate to drive the second hinge block to rotate on the outer wall of the damper. Fix the entire device through the fixed mounting plate, connect the conveying pipe and the first return pipe through the second flange plate, and then rotate the conveying pipe to drive the threaded sleeve to connect with the connecting water pipe. Pump the irrigation water through the main water pipe into the connecting water pipe and the conveying pipe. Then the water flows into the internal of the filter tank, and the large particle impurities in the water are filtered through the filter screen. The filter screen can be conveniently removed from the internal of the filter tank by pulling the sealing plate, or the cylinder connected to the bracket can be started to drive the brush to continuously move on the outer wall of the filter screen to clean the filter screen without affecting the normal operation of the filter screen. When the irrigation water flows in the connecting water pipe, the water flow is conveyed to the middle of the connecting water pipe through the diversion plate inside the protective cover to drive the turbine to rotate.

The water in the conveying pipe is injected into the internal of the connecting pipe through multiple hoses and finally drips out through the drip heads for drip irrigation. When the drip irrigation range needs to be adjusted, start the first motor to drive the rotating rod to rotate. The rotating rod drives the driving gear to rotate. The driving gear drives the driven gear to rotate. The driven gear drives the rotating shaft to rotate inside the second connecting plate. The rotating shaft drives the conveying pipe and the drip heads to rotate to expand the effective range of drip irrigation.

Rotate the grip to drive the second connecting block to drive the second rotating block to impact the first rotating block to drive the second connecting block to rotate. The second connecting block drives the worm to rotate, realizing the conversion of the energy generated by the impact of the second rotating block on the first rotating block into the ability of the worm to rotate, and realizing the precise adjustment of the drip irrigation flow rate.

[0016] The present invention provides a precise drip irrigation device with an automatic adjustment function. It has the following beneficial effects: 1. Through the cooperation between the power generation component and the adjustment component, the present invention achieves the effect of using expensive hydraulic power generation to store electrical energy in the storage battery to supply power to the motor, and drives the adjustment component through the motor to adjust the effective range of the dripping of the drip heads. At the same time, it is convenient to replace the drip heads by rotating the drip heads, solving the problem that the capillary tube can only wet the cotton area around the drip irrigation holes, resulting in uneven humidity in the entire cotton field, and further causing insufficient water supply for some planted plants and affecting the overall quality.

[0017] 2. By adjusting the cooperation between the adjusting component and the first rotating block and the second rotating block, the present invention achieves the function of controlling the flow rate while realizing the precise control of drip irrigation, and solves the problem that it is difficult for the traditional drip irrigation system to accurately adjust the water volume according to the real-time condition of the soil.
