[0012] Further, the control valve is fixed to the other end of the sand setting pipe.

[0013] The beneficial effect of the further scheme is that the sand and stones in the sand setting pipe can be quickly flushed out to the outside by opening the control valve, improving the irrigation efficiency.

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] like Figure 1-Figure 2 As shown, this embodiment provides an irrigation filtering and sedimentation device, including a water inlet pipe 1, a filter screen 2, a solenoid valve 3 and a sedimentation pipe 4. The solenoid valve 3 is fixed to the water outlet end of the water inlet pipe 1, and one side of the water inlet pipe 1 is fixedly connected and communicated with one end of the sedimentation pipe 4. The filter screen 2 is located between the sedimentation pipe 4 and the solenoid valve 3, and is detachably connected to the water inlet pipe 1.

[0028] Under the action of hydraulic pressure, the water flow in the water inlet pipe 1 flushes water and gravel to the filter screen 2 for filtration. The filter screen 2 intercepts the gravel in the water flow and traps it in the water inlet pipe 1. Opening the solenoid valve 3 allows the water in the water flow to flow to the fields, preventing the gravel from clogging or damaging the solenoid valve 3, thus saving costs. At the same time, the gravel is discharged to the outside through the sedimentation pipe 4 under the action of gravity and hydraulic pressure, thus completing the sand and gravel cleaning.

[0029] Specifically, one side of the water inlet pipe 1 is fixedly connected to and communicated with the water inlet end of the sand settling pipe 4 .

[0030] The filter screen 2 is made of stainless steel, which can increase the service life of the filter screen 2.

[0031] In addition, the water inlet pipe 1, the filter screen 2 and the solenoid valve 3 can be an integrated structure.

[0032] On the basis of the above solution, the filter screen 2 has protrusions on both sides, the water inlet pipe 1 has grooves corresponding to the protrusions one by one, and the protrusions are snap-connected to the grooves.

[0033] It is convenient for workers to replace and disassemble the filter 2, saving costs.

[0034] On the basis of the above solution, a metering pump is further included, and the metering pump is fixedly connected to the other side of the water inlet pipe 1.

[0035] The liquid medicine can be added into the water inlet pipe 1 through a metering pump, mixed with the water flow in the water inlet pipe 1, and then flowed to the field through the filter screen 2 to spray the crops in the field without the need for a separate spraying device.

[0036] On the basis of the above solution, a control valve 5 is further included, and the control valve 5 is fixed to the other end of the sand settling pipe 4.

[0037] Opening the control valve 5 can quickly flush the sand and gravel in the sedimentation pipe 4 to the outside, thereby improving the irrigation efficiency.

[0038] Specifically, in this embodiment, a controller is further included, and both the solenoid valve 3 and the control valve 5 are communicatively connected to the controller.

[0039] On the basis of the above solution, the control valve 5 is a ball valve or a plug valve.

[0040] Specifically, the control valve 5 can also be a hand-operated and electric-controlled ball valve, which can be used to regularly clean sand and gravel through the controller, or can be manually controlled according to on-site conditions to ensure that the sediment can be flushed out of the sedimentation pipe 4.

[0041] On the basis of the above solution, the sand settling pipe 4 is fixedly connected to and communicated with one side close to the water outlet end of the water inlet pipe 1 .

[0042] The sand and gravel filtered and intercepted by the filter screen 2 can flow directly to the sedimentation pipe 4 under the action of gravity and water pressure, so that the sand and gravel in the water inlet pipe 1 can be removed without dismantling the water inlet pipe 1 or stopping the water supply, saving costs and improving irrigation efficiency.

[0043] On the basis of the above solution, the horizontal distance between the sand settling pipe 4 and the outlet end of the water inlet pipe 1 is 5 cm-10 cm.

[0044] Specifically, the smaller the horizontal distance between the sand settling pipe 4 and the outlet end of the water inlet pipe 1 , the better, so as to avoid the sand and gravel filtered and intercepted by the filter screen 2 from being blocked in the water inlet pipe 1 .

[0045] The horizontal distance between the sand settling pipe 4 and the outlet end of the water inlet pipe 1 is the distance from the outer wall of the sand settling pipe 4 to the outlet end of the water inlet pipe 1 .

[0046] On the basis of the above solution, the sedimentation tube 4 is vertically arranged, and its length is 20cm-30cm.

[0047] Specifically, the longer the length of the sand settling tube 4 in the vertical direction is, the better.

[0048] The wall thickness of the sand settling tube 4 is 4 mm, which can increase the service life of the sand settling tube 4.

[0049] On the basis of the above solution, the filter screen 2 is a circular filter screen.

[0050] Specifically, the diameter of the filter screen 2 is the same as that of the water inlet pipe 1 to prevent sand and gravel from flowing toward the solenoid valve 3 through the gap between the filter screen 2 and the inner wall of the water inlet pipe 1 , thereby preventing the solenoid valve 3 from being blocked or damaged.

[0051] On the basis of the above solution, the filter screen 2 has a plurality of filter holes, and the pore diameter of the filter holes is 5 mm.

[0052] The filter 2 with a pore size of 5 mm can filter out more small-diameter sand and gravel, thereby improving the filtering effect.

[0053] Specifically, filter screens 2 with different apertures can be provided according to actual conditions.

[0054] In this embodiment, when in use, the water flow in the water inlet pipe 1 flushes the water and sand and gravel to the filter 2 under the action of water pressure for filtration. The filter 2 intercepts the sand and gravel in the water flow in the water inlet pipe 1, and the sand and gravel flow to the sedimentation pipe 4 under the action of gravity.

[0055] Opening the solenoid valve 3 allows the water in the stream to flow to the field, and opening the control valve 5 can quickly flush the sand and gravel in the sedimentation pipe 4 to the outside, preventing the sand and gravel from clogging or damaging the solenoid valve 3, saving costs and improving irrigation efficiency.
