Description

Technical Field

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

[0002] The Yellow River Basin is a resource-based water-deficient area with less water and more sand, an uncoordinated relationship between water and sand, and extremely uneven distribution of water resources and arable land resources. These characteristics determine the important role of Yellow River irrigation in agricultural production. The implementation of total water resource control and water rights allocation and reasonable transfer has become an important guarantee for the sustainable use of water resources, the coordinated development of social economy and irrigation agriculture in the Yellow River Basin. Drip irrigation uses low-pressure and low-flow outflow to transport irrigation water to the root zone of crops and slowly and evenly infiltrate the soil to meet the needs of crops, with significant water-saving and yield-increasing effects. The sheet drip irrigation technology can effectively save water resources. Its functions and advantages of increasing yield, improving the quality of agricultural products, saving water and fertilizer, saving fertilizer and labor are widely recognized, and a complete and mature theory has been formed 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 shortage of water resources 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. The most serious impact on the drip irrigation system is the blockage of the drip irrigation system, and the 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, and suspended matter, dissolved salts, chemical precipitation, organic matter, microorganisms and other impurities 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 solving this problem 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. There are still a large number of smaller particles entering the drip irrigation system through the filter, which in turn causes clogging in the emitter and affects its use. For this reason, we proposed a sheet-type emitter for drip irrigation in the Yellow River. Summary of the invention

[0003] The present invention provides a sheet-type emitter for drip irrigation of the Yellow River, which solves the problems raised by the above-mentioned background technology.

[0008] Optionally, a detachable cover plate is installed on the top of the emitter base, a rubber sealing pad is provided at the connection between the cover plate and the emitter base, and the cover plate is installed on the emitter base by bolts.

[0009] Optionally, the ratchet mechanism includes a ratchet and a spring, the ratchet being movably connected to the emitter base, one end of the ratchet being in a quarter-circle shape and plugged into the outer side of the connecting conversion seat, the other end of the ratchet being fixedly connected to a spring, one end of the spring being fixed to the emitter base.

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

A conveying water path 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 conveying water path 15 can be connected to a connecting water path 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 be rotated to irrigate, so that the range of irrigation is wider.

When the filter screen plate 11 is blocked, the water enters the connecting waterway 7 and the water pressure continues to increase. The connecting water channel 7 structure can push the connecting conversion seat 6 to rotate, and with the cooperation of the subsequent water flow driving groove 10, the connecting conversion seat 6 can rotate, and then the connecting water channel 7 is switched. When the filter screen 11 rotates, the filter screen 11 can contact the brush assembly 12. Under the action of the brush assembly 12, the filter screen 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, the connecting conversion seat 6 can be limited again under the action of the elastic force of the spring 14.
