Description

Technical Field

[0001] The invention relates to the technical field of emitters, in particular to a sheet-type emitter for Yellow River drip irrigation. Background Art

[0002] The Yellow River Basin is a resource-scarce region characterized by limited water resources and abundant sediment, an unbalanced water-sediment relationship, and a highly uneven distribution of water and arable land resources. These characteristics underpin the crucial role of Yellow River irrigation in agricultural production. Implementing total water resource control, as well as the allocation and rational transfer of water rights, has become a crucial measure to ensure the sustainable utilization of water resources and the coordinated development of socioeconomic and irrigated agriculture in the Yellow River Basin. Drip irrigation, which delivers irrigation water at low pressure and low flow rates to the crop root zone, slowly and evenly infiltrates the soil, meeting crop needs and significantly reducing water consumption and increasing yields. Slice-type drip irrigation technology effectively conserves water, increases yield, improves agricultural product quality, and conserves water, fertilizer, and labor. Its benefits are widely recognized, and its theoretical foundation has been fully developed in practice. However, with the rapid development of industry and agriculture in the Yellow River Basin, the water resources of the Yellow River are becoming increasingly scarce. Drought and water shortage have seriously restricted the economic and social development of the Yellow River irrigation area. The use of Yellow River drip irrigation has become an important way to alleviate the water shortage problem in the Yellow River area. The Yellow River drip irrigation technology has also played an important role in the implementation of a number of major projects such as the "four 10 million mu" water-saving irrigation in the Inner Mongolia Autonomous Region and the Ningmeng Yellow River water rights conversion. With the advancement of Yellow River drip irrigation, the drip irrigation system has continued to develop. Among them, the most serious impact on the drip irrigation system is the blockage of the drip irrigation system, and the most prominent manifestation of the blockage of the drip irrigation system is the blockage of the emitter. The main reason is that the flow channel size of the emitter is generally only 0.5-1.2mm. Impurities such as suspended matter, dissolved salts, chemical precipitation, organic matter, and microorganisms in the water can easily cause the emitter to be blocked. Emitter clogging has become a key obstacle in the promotion and application of drip irrigation technology. The success of its solution directly determines the service life and application benefits of the drip irrigation system. However, due to the high sediment content of the Yellow River itself, although various engineering measures can effectively control the content of suspended particulate matter, it is impossible to completely remove it. A large number of smaller particles still pass through the filter into the drip irrigation system, causing blockage in the emitter and affecting its use. For this reason, we proposed a sheet-type emitter for Yellow River drip irrigation. Summary of the Invention

[0015] 2. The sheet-type water emitter for Yellow River drip irrigation has a brush assembly arranged on a fixed seat. When the connecting water channel rotates and switches, its filter plate rotates along with it. After the filter plate rotates and switches, the subsequent rotation of the filter plate can enable the brush assembly to automatically brush the filter plate, thereby unblocking the filter plate, thereby effectively solving the problem of its blockage.

[0016] 3. This plate-type emitter for Yellow River drip irrigation, through the action of the ratchet mechanism, increases the water pressure in its connecting waterway when the filter screen plate is clogged. When the water pressure exceeds the threshold value defined by the ratchet mechanism, it can push the connecting conversion seat to rotate, thereby enabling the connecting conversion seat to stably deliver water while ensuring the timely switching of the connecting waterway, making it more convenient to use.

When blockage occurs in the connecting water channel 7, the water pressure in the connecting water channel 7 continues to rise, which enables it to push the connecting conversion seat 6 to rotate, and the outer end of the connecting water channel 7 can be connected to the water inlet pipe 2, so that water can enter the connecting water channel 7, and a filter screen 11 is fixedly installed inside the inner end of the connecting water channel 7. Under the action of the mesh plate 11, the water can be filtered again. A water delivery channel 15 that can be connected to the water outlet component 3 is opened on the fixed seat 5, so that the water can enter the water outlet component 3 and be irrigated. One end of the water delivery channel 15 can be connected to a connecting water channel 7 together with the water inlet pipe 2. At the same time, a water flow driving device that can drive the water outlet component 3 to rotate is installed in the fixed seat 5. Under the promotion of the water flow driving device, the water outlet component 3 can rotate to irrigate, thereby making its irrigation range wider. At the same time, a ratchet mechanism that can limit the connecting conversion seat 6 is installed in the sprinkler base 1. When the water pressure driving force in the connecting water channel 7 is greater than the threshold value defined by the ratchet mechanism, it can drive the connecting conversion seat 6 to rotate.

When the filter screen plate 11 is blocked, the water enters the connecting waterway 7 and the water pressure continues to increase. Large, under the action of the connecting water channel 7 structure, it can push the connecting conversion seat 6 to rotate, and under the cooperation and push of the subsequent water flow pushing groove 10, the connecting conversion seat 6 can rotate, and then the connecting water channel 7 is switched. When the filter screen plate 11 rotates, the filter screen plate 11 can contact the brush assembly 12. Under the action of the brush assembly 12, the filter screen plate 11 can be cleaned, and the cleaned debris can fall into the collection frame 9 for storage. When the connecting water channel 7 on the connecting conversion seat 6 is switched, under the action of the elastic force of the spring 14, the connecting conversion seat 6 can be re-defined.
