[0001] The utility model belongs to the technical field of agriculture, and in particular relates to an anti-blocking device for an agricultural drip irrigation belt. Background Art

[0002] Drip irrigation technology is an effective irrigation method, especially suitable for water-saving and efficient agriculture. Drip irrigation is an irrigation method that delivers a certain amount of water and fertilizer to the roots of plants drop by drop. Drip irrigation provides growers with an accurately controlled irrigation and fertilization mode, which can scientifically and rationally ensure the water and nutrient needs of crops and maximize the use of limited water resources. Drip irrigation products can be drip tapes, drip pipes or drippers.

[0003] In the prior art, when using an automatic drip irrigation device, river water or well water is extracted, filtered first, and then the water is passed into the drip irrigation belt to drip irrigate the soil. However, when pumping water, the well water or river water with sludge is extracted, and when filtering, all the sludge cannot be filtered out. During drip irrigation, the sludge will flow from the water inlet end of the drip irrigation belt to the end of the drip irrigation belt with the water flow. However, since the end of the drip irrigation belt needs to be closed to increase the water pressure, the sludge accumulates at the end of the drip irrigation belt, causing the drip irrigation belt to be blocked. Utility Model Content

[0004] The utility model aims to provide an anti-blocking device for an agricultural drip irrigation belt, so as to solve the problem that when the existing drip irrigation belt is used, sludge accumulates at the end of the drip irrigation belt, causing the drip irrigation belt to be blocked.

[0006] The above-mentioned sewage discharge component includes a rotating plate, one end of the rotating plate close to the water receiving component is connected to the clamping block, a sealing plate is arranged on the top of the rotating plate away from the water receiving component, linkage blocks are arranged on the top of both sides of the sealing plate, the sealing plate is rotatably connected to a connecting plate via the linkage block, and a resistance block acting on the drip irrigation belt body is arranged on one side of the connecting plate.

[0007] In one embodiment, a first rotating shaft is disposed inside the U-shaped block, and the rotating plate is rotatably connected to the first rotating shaft.

[0008] In one of the embodiments, a fixing plate is arranged inside the U-shaped block, a sleeve block sleeved on the drip irrigation tape body is arranged on the top of the fixing plate, and the end of the drip irrigation tape is located in the sleeve block.

[0009] In one embodiment, second rotating shafts are disposed on both sides of the sleeve block, and a cutout is formed at the bottom of the sleeve block.

[0010] In one embodiment, each of the linkage blocks is slidably engaged with one of the second rotating shafts.

[0011] In one embodiment, the stop block is located in the cutout of the sleeve block after rotation.

[0012] In one of the embodiments, a water leakage hole is provided at the bottom of the water receiving box to facilitate water dripping.

[0030] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In order to avoid confusion with the present invention, some technical features known in the art are not described.

[0031] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0032] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0033] Please refer to Figure 1-Figure 7 The anti-blocking device for an agricultural drip irrigation tape shown comprises a drip irrigation tape body 1 and a fixing assembly arranged at the end of the drip irrigation tape body 1.

[0034] In this embodiment, a fixing plate 204 is disposed inside the U-shaped block 201 , a sleeve block 205 sleeved on the drip irrigation tape body 1 is disposed on the top of the fixing plate 204 , and the end of the drip irrigation tape body 1 is located in the sleeve block 205 .

[0035] like Figure 1-Figure 2 As shown, the end of the drip irrigation tape body 1 is arranged in the sleeve block 205, and the end of the sleeve block 205 is in an arc shape.

[0036] In this embodiment, a first rotating shaft 203 is disposed inside the U-shaped block 201 , and the rotating plate 221 is rotatably connected to the first rotating shaft 203 .

[0037] like Figure 4 As shown, when the water receiving box 211 moves upward, the rotating plate 221 can be driven to rotate around the first rotating shaft 203 .

[0038] In this embodiment, second rotating shafts 206 are provided on both sides of the sleeve block 205, and a cutout 207 is opened at the bottom of the sleeve block 205. Each linkage block 223 is slidably engaged with one of the second rotating shafts 206, and the stop block 225 is located in the cutout 207 of the sleeve block 205 after rotation.

[0039] like Figure 4 As shown, when the rotating plate 221 rotates with the sealing plate 222 , the connecting plate 224 and the abutting block 225 can be brought close to and abut against the drip irrigation tape body 1 through the relationship between the linkage block 223 and the second rotating shaft 206 .

[0040] In this embodiment, the fixed component includes a C-shaped block 201, which is slidably connected to a water receiving component via a sliding slot 202. The water receiving component includes a water receiving box 211. The water receiving box 211 is located directly below a drip hole on the front side of the end of the drip irrigation belt body 1, and can receive water dripping from the drip hole. A leakage hole 2111 is provided at the bottom of the water receiving box 211 for facilitating dripping. The leakage speed of the leakage hole 2111 is lower than the dripping speed of the drip hole on the drip irrigation belt body 1 under normal conditions. The water receiving box 211 is slidably set in the sliding slot 202 via a sliding block 212. The water receiving box 211 is slidably connected to the sliding block 212, and a pressure spring 214 is provided between the sliding block 212 and the limiting plate 213.

[0041] A limiting plate 213 is arranged on the circumferential side of the top of the water receiving box 211, and a clamping block 215 is arranged on the side of the bottom of the limiting plate 213 near the end of the drip irrigation belt body 1. The limiting plate 213 is connected to a sewage discharge component via the clamping block 215. The sewage discharge component includes a rotating plate 221, and one end of the rotating plate 221 near the water receiving component is connected to the clamping block 215. A sealing plate 222 is arranged on the top of the rotating plate 221 away from the end of the water receiving component. Linkage blocks 223 are arranged on the tops of both sides of the sealing plate 222. The sealing plate 222 is rotatably connected to a connecting plate 224 via the linkage block 223. A stop block 225 acting on the drip irrigation belt body 1 is arranged on one side of the connecting plate 224. The stop block 225 is attached to the sleeve block 205, and the arc centers of the stop block 225 and the sleeve block 205 are both the first rotating shaft 203.

[0042] like Figure 3-Figure 7 As shown, when the end of the drip irrigation tape body 1 is blocked by sludge, the dripping speed of the drip hole on the drip irrigation tape body 1 slows down. At this time, the leakage speed of the leakage hole 2111 is greater than the dripping speed of the drip hole on the drip irrigation tape body 1 under normal conditions. The weight of the water receiving box 211 and the water in the water receiving box 211 becomes lighter. At this time, the water receiving box 211 moves upward under the action of the pressure spring 214.

[0043] When the pressure spring 214 moves upward, the sealing plate 222 is driven to separate from the sleeve block 205 through the rotating plate 221, and the end of the drip irrigation tape body 1 is no longer sealed, so that the sludge can be discharged from the end of the drip irrigation tape body 1, and the stop block 225 is against the side wall of the drip irrigation tape body 1 during the rotation. Since the drip irrigation tape body 1 is made of plastic, the stop block 225 can change the shape of the accumulated sludge to a certain extent, and can increase the speed at which the sludge is discharged from the end of the drip irrigation tape body 1 to a certain extent.

[0044] Working principle: When the anti-blocking device for agricultural drip irrigation belt is used, if the end of the drip irrigation belt body 1 is blocked by sludge after a period of drip irrigation, the drip hole near the end of the drip irrigation belt body 1 will also be affected, and the amount of water dripping from the drip hole into the water receiving box 211 will be less than the amount of water leaking from the leakage hole 2111 at the bottom of the water receiving box 211. At this time, the total weight of the water receiving box 211 and the water in the water receiving box 211 is reduced, and the water receiving box 211 moves upward under the action of the pressure spring 214. The pressure spring 214 drives the rotating plate 221 to rotate around the first rotating shaft 203, and the rotating plate 221 drives the sealing plate 222 to separate from the sleeve block 205, so that the sludge at the end of the drip irrigation belt body 1 is not blocked. When the rotating plate 221 rotates, the two linkage blocks 223 and the connecting plate 224 drive the abutment block 225 to rotate, and the abutment block 225 will abut against the end of the drip irrigation belt body 1, so that the sludge at the end of the drip irrigation belt body 1 can be deformed to a certain extent, so that the sludge accumulated at the end of the drip irrigation belt body 1 is loosened and flushed out by water.

[0045] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
