Description

Technical Field

[0001] The utility model relates to the technical field of drip irrigation tapes, in particular to a new type of drip irrigation tape specially for sandy land. Background Technique

[0002] Drip irrigation tapes are mainly used for agricultural irrigation and are an efficient water-saving irrigation method. The drip irrigation tape evenly and slowly drips water into the soil near the roots of crops through connecting blocks or drip irrigation tapes with very small outflow orifices on a capillary tube with a diameter of about 16 mm, achieving local irrigation. This irrigation method can effectively improve the utilization rate of water and fertilizer, and achieve the planting effect of water and energy conservation.

[0003] When drip-irrigating sandy land, in order to achieve water conservation, improve water utilization rate, reduce soil erosion and improve the ecological environment, drip irrigation with a drip irrigation tape is required. In the prior art, most drip irrigation tapes are provided with a labyrinth channel inside the connecting block during use, and the flow channel shape is "Great Wall" shape. This "Great Wall" shaped labyrinth channel is composed of a plurality of transverse flow channels arranged in two staggered rows along the length direction of the drip irrigation tape and vertical flow channels connecting the upper and lower transverse flow channels at the head and tail. Water flows from the main water channel of the drip irrigation tape into the labyrinth channel, and through the labyrinth channel, the water flows to the water outlet and drips out from the water outlet. Sand and gravel in the sandy soil will cause blockage to the connecting block. However, when the drip irrigation tape is in use, water flows for a long time and scale will form inside the inlet channel, and the scale will cause blockage to the inlet channel, affecting the water flow and bringing a lot of trouble to the drip irrigation work, seriously affecting the drip irrigation work and having insufficient practicability. Therefore, it is necessary to redesign a new type of drip irrigation tape specially for sandy land to solve the above problems. Content of the Utility Model

A moving block 7 is threadedly installed on the outer wall of the screw rod 4 through a limiting mechanism. The limiting mechanism includes a limiting rod 6 fixedly installed inside the lifting frame 3. The limiting rod 6 slidably penetrates through the moving block 7. The limiting rod 6 can limit the moving block 7, so that the moving block 7 can only axially move along the outer wall of the screw rod 4. A clamping frame 8 is fixedly installed at the end of the moving block 7. A first clamping plate 10 is fixedly connected to the inner bottom wall of the clamping frame 8 through a support mechanism. The support mechanism includes a support rod 9 fixedly installed on the inner bottom wall of the clamping frame 8. The end of the support rod 9 is fixedly connected to the outer wall of the first clamping plate 10.

[0027] The inner wall of the clamping frame 8 is fixedly connected with a second clamping plate 12 through a telescopic mechanism. The telescopic mechanism includes a cylinder 11 fixedly installed on the inner wall of the clamping frame 8. The telescopic end of the cylinder 11 is fixedly connected with the outer wall of the second clamping plate 12. The connecting pipe 2 is slidably installed between the first clamping plate 10 and the second clamping plate 12. Both the first clamping plate 10 and the second clamping plate 12 have arc-shaped inner walls. Protective pads 13 are fixedly installed on the arc-shaped inner walls of the first clamping plate 10 and the second clamping plate 12. One end of the connecting pipe 2 is fixedly installed with a drip irrigation tape body 14. A connecting block 15 is fixedly installed on the outer wall of the drip irrigation tape body 14. A labyrinth channel is opened inside the connecting block 15. A plurality of inlet channels communicating with the drip irrigation tape body 14 are opened on the inner wall of the labyrinth channel. Two drip irrigation openings communicating with the outer wall of the connecting block 15 are opened inside the labyrinth channel. The outer wall of the drip irrigation tape body 14 is slidably installed with extrusion rods 17 corresponding to a plurality of inlet channels through a sealing mechanism. The sealing mechanism includes a mechanical seal 16 fixedly installed on the outer wall of the drip irrigation tape body 14. The extrusion rods 17 slidably penetrate through the mechanical seal 16. A through needle 18 is fixedly installed on the bottom wall of each extrusion rod 17. A pressing block 19 is fixedly installed on the outer wall of each extrusion rod 17. A return spring 20 is installed on the outer wall of each extrusion rod 17. Two ends of each return spring 20 are elastically connected to the upper end face of the corresponding mechanical seal 16 and the bottom wall of the pressing block 19 respectively.

[0028] The outer wall of the other end of the connecting pipe 2 is fixedly installed with a filter cylinder 21. A filter element 22 is slidably installed inside the filter cylinder 21. A cover plate 23 is slidably installed on the upper end face of the filter cylinder 21. A sealing gasket 24 matched with the cover plate 23 is fixedly installed on the upper end face of the filter cylinder 21. The sealing gasket 24 is made of vulcanized rubber. Vulcanized rubber refers to rubber that has been vulcanized and has characteristics such as non-stickiness, non-breakability, etc. It also has high elasticity, heat resistance, tensile strength and insolubility in organic solvents, etc. A fixing pin 25 is slidably penetrated through the outer wall of the cover plate 23. A jack matched with the fixing pin 25 is opened on the outer wall of the filter cylinder 21. A dial block 26 is fixedly installed on the outer wall of the fixing pin 25. The inner wall of the dial block 26 is connected with the outer wall of the cover plate 23 through a fixing mechanism. The fixing mechanism includes a fixing spring 27 installed on the outer wall of the fixing pin 25. Two ends of the fixing spring 27 are elastically connected to the outer wall of the cover plate 23 and the inner wall of the dial block 26 respectively.

[0029] When the utility model is in use, the connecting pipe 2 can be first placed between the first clamping plate 10 and the second clamping plate 12. Immediately afterwards, the air cylinder 11 can drive the second clamping plate 12 to move downwards, so that the first clamping plate 10 and the second clamping plate 12 can approach each other, and the connecting pipe 2 can be clamped and fixed by the protective pad 13. When the drip irrigation belt body 14 is in use, the rocker 5 can be rotated to drive the screw rod 4 to rotate. When the screw rod 4 rotates, it can drive the moving block 7 to move through the cooperation with the limiting rod 6, so that the moving block 7 can drive the clamping frame 8 to move, thereby driving the clamped and fixed connecting pipe 2 to move up and down, so as to conveniently adjust the use height of the drip irrigation belt body 14;

[0030] When drip irrigation is carried out on sandy land, the water inlet pipe can be connected to the water pipe. Subsequently, the filter element 22 can be slidably installed inside the filter cylinder 21, and the cover plate 23 can be slidably installed on the upper end face of the filter cylinder 21. At this time, the fixing spring 27 can drive the fixing pin 25 to move into the jack, thereby realizing the fixation of the cover plate 23 and the outer wall of the filter cylinder 21. The sealing gasket 24 can increase the sealing performance between the upper end face of the filter cylinder 21 and the bottom wall of the cover plate 23. Immediately afterwards, the water pipe can output water into the filter cylinder 21. The filter element 22 inside the filter cylinder 21 can filter impurities in the water, preventing the impurities in the water from flowing into the drip irrigation belt body 14 and causing blockage. The water can flow into the labyrinth channel inside the drip irrigation belt body 14 through multiple inlet channels, and then leak out through two drip irrigation openings from the labyrinth channel for drip irrigation. When the inner wall of the inlet channel forms scale and causes blockage, the pressing block 19 can be pressed downwards. At this time, the pressing block 19 can drive the pressing rod 17 to slide in the mechanical seal 16 and compress the return spring 20, so that the pressing rod 17 can drive the through needle 18 to move downwards to dredge the inlet channel, thereby preventing the scale from blocking the inlet channel and affecting the drip irrigation of sandy land. When the pressing block 19 is not stressed, the return spring 20 can drive the pressing rod 17 to move back to its original position, so that the through needle 18 can move back to its original position, thereby preventing the through needle 18 from affecting the flow effect of the inlet channel. When it is necessary to clean and replace the filter element 22, the dial block 26 can be toggled to drive the fixing pin 25 to move out of the jack, thereby releasing the fixation of the cover plate 23. Subsequently, the cover plate 23 can be removed to disassemble the filter element 22.

[0031] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the utility model.
