Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation equipment, and more specifically, to a water-pesticide-fertilizer mixed irrigation device. Background Technology

[0002] Irrigation is a technical measure to supplement the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, it is necessary to supply crops with sufficient water. Under natural conditions, the water requirements of crops are often not met due to insufficient rainfall or uneven distribution. Therefore, it is necessary to carry out irrigation artificially to make up for the lack of natural rainfall. In order to help crops obtain sufficient nutrients and resist pests and diseases, people usually dissolve pesticides and fertilizers in irrigation water. This irrigation method requires the use of water-pesticide-fertilizer mixed irrigation devices.

[0003] Existing water-pesticide-fertilizer mixed irrigation devices mainly consist of a control cabinet, a mixer, a booster pump, a centrifugal filter, a mesh filter, a delivery pipeline, and an irrigation head. During use, the control cabinet controls the mixer to agitate the pesticides and fertilizers with the irrigation water, dissolving them in the water. Then, the control cabinet controls the booster pump to pressurize the irrigation water. Under hydraulic pressure, the irrigation water passes through the mesh filter and delivery pipeline and is sprayed out from the irrigation head, achieving the purpose of irrigation, pesticide application, and fertilization. However, the irrigation head is prone to clogging during use, causing irrigation to malfunction. Therefore, there is an urgent need to design a water-pesticide-fertilizer mixed irrigation device.

[0024] Working principle: First, the mixing agitator 103 is turned on via control cabinet 102. Then, the mixing agitator 103 mixes the irrigation water and fertilizer inside, causing the fertilizer to gradually dissolve in the irrigation water. Next, the booster pump 105 is operated via control cabinet 102. Driven by the booster pump 105, the irrigation water inside the mixing agitator 103 flows through the outlet pipe 104, booster pump 105, inlet bend pipe 106, centrifugal filter 107, mesh filter 108, discharge pipe 109, distribution pipe 110, and branch pipe 111 into the irrigation head 2. During this process, the centrifugal filter 107 performs a primary filtration of the irrigation water, and the mesh filter 108 performs a secondary filtration, removing particulate matter from the irrigation water. Then, the irrigation water... Irrigation water enters the inverted cone cavity 24 through the internal threaded connector 21 and the external threaded connector 22. The hydraulic pressure inside the inverted cone cavity 24 then increases. Irrigation water then enters the arc-shaped channel cavity 62 through the constant pressure bent pipe 41. The hydraulic pressure inside the arc-shaped channel cavity 62 gradually increases. Under the influence of the hydraulic pressure difference, the arc-shaped piston 63 slides along the arc-shaped channel cavity 62. The arc-shaped piston 63 then moves the arc-shaped linkage rod 64 in a circular motion. The arc-shaped linkage rod 64 then moves the linkage straight arm 65 in a circular motion. The linkage straight arm 65 on the left side of the irrigation column 25, along with the corresponding alternating ratchet 54, rotates inwards along a direction perpendicular to the paper. The linkage straight arm 65 then pulls the corresponding return spring 73, causing the return spring 73 to stretch elastically and increase its elastic potential energy. Then, the corresponding alternating ratchet 54 drives the corresponding alternating rotating rod 55 to rotate inwards along the direction perpendicular to the paper. The alternating rotating rod 55, through its one-way meshing with the alternating spring 53, drives the corresponding alternating cylinder 51 to rotate inwards along the direction perpendicular to the paper. Next, the alternating cylinder 51 drives the alternating shaft 52 to rotate. Then, the alternating shaft 52 drives the alternating ball 34 to rotate. Then, the alternating ball 34 drives the alternating shaft 52 on its right side to rotate inwards along the direction perpendicular to the paper. Next, this alternating shaft 52 drives the alternating cylinder 51 on its right end to rotate inwards along the direction perpendicular to the paper. Then, the corresponding alternating cylinder 51 drives the alternating spring 53 to rotate inwards along the direction perpendicular to the paper. Finally, the alternating spring 53 rotates along the alternating rotating rod 55... The surfaces slide without engaging. Simultaneously, the linkage straight arm 65 on the right side of the irrigation column 25, along with the corresponding alternating ratchet 54, rotates outwards along the direction perpendicular to the paper. Then, the corresponding alternating ratchet 54, along with the corresponding alternating rotating rod 55, rotates outwards along the direction perpendicular to the paper. Afterwards, the alternating ball 34, along with the irrigation hole 27, the receiving conical groove 35, and the ball-centered buffer cavity 36, rotates inwards along the direction perpendicular to the paper, with the alternating ratchet 54 as the central axis. Then, the arc piston 63 contacts the end face of the inner cavity of the arc channel cavity 62. At this time, the alternating ball 34 has rotated forty-five degrees, one irrigation hole 27 is in a vertical state, and the receiving conical grooves 35 at both ends slide out from the spherical sealing sleeve 33, so that the two receiving conical grooves 35 are in an open state.Another irrigation hole 27 is horizontal, and the receiving conical grooves 35 at both ends are still inside the spherical sealing sleeve 33, thus blocking these two receiving conical grooves 35. Then, the irrigation water inside the inverted cone cavity 24 is discharged through the vertical receiving conical grooves 35, the spherical buffer cavity 36, the irrigation hole 27, and the irrigation groove 26, achieving the effect of irrigation and fertilizer application. At the end of irrigation, the mixing agitator 103 and the booster pump 105 are turned off by the control cabinet 102. Then, the residual irrigation water inside the inverted cone cavity 24 seeps out from the irrigation groove 26 under the action of residual hydraulic pressure. Then, the hydraulic pressure inside the inverted cone cavity 24 gradually decreases. Then, the linkage straight arm 65 on the left side of the irrigation column 25, under the action of the elastic tension of the corresponding return spring 73, drives the corresponding alternating ratchet 5. 4. Rotate outwards along the direction perpendicular to the paper. Then, the corresponding alternating ratchet 54 drives the alternating rotating rod 55 to rotate outwards along the direction perpendicular to the paper. Then, the corresponding alternating spring 53 slides on the surface of the alternating rotating rod 55 without engaging. Next, the linkage straight arm 65 on the right side of the irrigation column 25, under the elastic tension of the corresponding return spring 73, drives the corresponding alternating ratchet 54 to rotate inwards along the direction perpendicular to the paper. Then, the alternating ratchet 54 drives the corresponding alternating rotating rod 55 to rotate inwards along the direction perpendicular to the paper. Then, the alternating rotating rod 55, through its meshing with the corresponding alternating spring 53, drives the corresponding alternating cylinder 51 to rotate again inwards along the direction perpendicular to the paper. Then, the alternating cylinder 51 rotates inwards along the direction perpendicular to the paper through alternating... The shaft 52, carrying the alternating ball 34, rotates again in a direction perpendicular to the paper and inwards. Then, the alternating ball 34, carrying the alternating shaft 52 on its left, rotates in a direction perpendicular to the paper and inwards. This alternating shaft 52, through the alternating cylinder 51, carries the corresponding alternating spring 53 in a direction perpendicular to the paper and inwards. Next, this alternating spring 53 slides on the surface of the corresponding alternating rotating rod 55 without engaging. Then, the linkage straight arm 65 contacts the end face of the semi-circular arc bar 61. At this point, the alternating ball 34 rotates another 45 degrees in a direction perpendicular to the paper and inwards. In this state, the receiving cone grooves 35 at the ends of both irrigation holes 27 rotate into the interior of the spherical sealing sleeve 33. Then, the spherical sealing sleeve 33 blocks the receiving cone grooves 35, preventing crop roots from invading the cavity. The problem of blockage caused by the receiving conical groove 35 and irrigation hole 27 is resolved, thus completing the irrigation work. If, during the irrigation process, irrigation head 2 fails to drain water, it indicates sediment has formed in the irrigation water. This sediment, under the influence of the water flow, enters the corresponding receiving conical groove 35 and blocks the irrigation hole 27. Then, the booster pump 105 is alternately turned on and off via the control cabinet 102. Each time the booster pump 105 is turned on, it must be allowed to stabilize before being turned off. Next, the alternating ball 34 will continuously rotate inwards perpendicular to the paper. Then, the alternating ball 34 rotates along with the irrigation hole 27 and the receiving conical groove 35. The receiving conical groove 35 then rotates along with the sediment inside, causing the irrigation hole 27 to turn around. Afterwards, the receiving conical groove 35 connects with the irrigation groove 26.Then, the irrigation water flows in reverse inside the irrigation hole 27, and the sediment inside the containment cone 35 flows out under the impact of the backwash water flow, achieving the effect of backwashing and unclogging.
