Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural irrigation, and particularly relates to an agricultural water-saving irrigation device. Background Art

[0002] During the agricultural planting process, it is necessary to irrigate the plants irregularly according to the soil conditions. At present, a drip irrigation system can be used to irrigate the plants specifically, which can achieve a good water-saving effect. The drip irrigation system will open holes corresponding to the positions of the plants on the pipeline, and the water body conveyed in the pipeline will irrigate the plants through the openings. However, in the actual use process, there is a situation where the holes opened in the drip irrigation pipeline are blocked due to the precipitation of impurities and chemical substances in the water body. It is necessary for the staff to hold a dredging pipeline to dredge each hole opened in the pipeline one by one. During the operation, the staff needs to detect each hole opened along the laying route of the drip irrigation pipeline one by one, and needs to bend down one by one to dredge the blocked openings, and the operation is cumbersome and inconvenient. Content of the Utility Model

[0003] The utility model provides an agricultural water-saving irrigation device, which has the characteristic of being able to dredge and clean the openings on the side wall of the perforated drip irrigation pipeline.

[0004] The utility model provides the following technical scheme: an agricultural water-saving irrigation device, including a perforated drip irrigation pipeline and two connecting joints. A traction rope is detachably connected between the two connecting joints. Two side convex sealing discs are arranged in the perforated drip irrigation pipeline. A limiting sealing ring is detachably connected to the outer wall of the side convex sealing disc. One side of the limiting sealing ring is fixedly connected with a sealing sleeve, and the sealing sleeve is sleeved on the outer wall of the side convex sealing disc. A relief hole is opened in one of the side convex sealing discs. A connecting rope group is fixedly connected between the two side convex sealing discs. One side of the side convex sealing disc provided with the relief hole is fixedly connected with a water delivery thin pipe.

[0005] Wherein, the diameter of the side convex sealing disc is smaller than the diameter of the perforated drip irrigation pipeline, and the limiting sealing ring and the sealing sleeve are attached to the inner wall of the perforated drip irrigation pipeline.

[0006] Wherein, a connecting traction ring is fixedly connected to one side of the other side convex sealing disc, and the traction rope is tied to the connecting traction ring.

[0007] Wherein, two pulling ropes are fixedly connected to the side wall of the limiting sealing ring, and the other ends of the pulling ropes are fixedly connected to the side convex sealing disc.

[0008] Wherein, a clamping convex block is fixedly connected to one side of the side convex sealing disc, and an inner concave clamping groove is opened on one side of the limiting sealing ring, and the clamping convex block is inserted into the inner concave clamping groove.

[0009] The beneficial effects of the utility model are:

[0010] 1. With the help of two separated side convex plugging discs, the limit sealing ring and the sealing sleeve are used to intercept part of the space inside the perforated drip irrigation pipe, and the water delivery tube is used to inject high-pressure water into the perforated drip irrigation pipe at the corresponding position of the two side convex plugging discs. The openings on the side wall of the perforated drip irrigation pipe can be quickly cleared with the help of high-pressure water, and there is no need to detect the openings one by one, which makes the operation more convenient.

[0011] 2. By using the boss shape of the side convex sealing disc to limit the position of the limiting sealing ring, when the side convex sealing disc moves forward under the traction of the traction rope, the limiting sealing ring and the sealing sleeve will not lose contact with the side convex sealing disc, and can effectively seal the gap between the side convex sealing disc and the inner wall of the perforated drip irrigation pipe. When the side convex sealing disc moves in the reverse direction, the limiting sealing ring and the sealing sleeve can be separated from the outer wall of the side convex sealing disc and pulled by the side convex sealing disc and the pulling rope, effectively reducing the resistance encountered when the side convex sealing disc is pulled out in the reverse direction, so that the side convex sealing disc can be smoothly taken out from the perforated drip irrigation pipe, and when the traction rope breaks, it can prevent the side convex sealing disc, the limiting sealing ring and the sealing sleeve from remaining in the perforated drip irrigation pipe, causing the perforated drip irrigation pipe to be blocked and scrapped.

[0012] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] See also Figures 1-4The utility model provides the following technical solutions: an agricultural water-saving irrigation device, comprising a perforated drip irrigation pipe 1 and two connecting joints 11, a traction rope 12 is detachably connected between the two connecting joints 11, two side convex plugging discs 2 are arranged in the perforated drip irrigation pipe 1, the outer wall of the side convex plugging disc 2 is detachably connected to a limited position sealing ring 21, one side of the limited position sealing ring 21 is fixedly connected to a sealing sleeve 22, the sealing sleeve 22 is sleeved on the outer wall of the side convex plugging disc 2, one of the side convex plugging discs 2 is provided with a clearance hole 23, a connecting rope group 24 is fixedly connected between the two side convex plugging discs 2, and one side of the side convex plugging disc 2 with the clearance hole 23 is fixedly connected to a water supply capillary 3.

[0019] In this embodiment, during normal irrigation operations, the traction rope 12 passes through the perforated drip irrigation pipe 1 and is connected to the two connection joints 11, and the connection joints 11 are connected to the external water delivery pipe. The water body drips the plants through the perforations on the perforated drip irrigation pipe 1. When the perforations on the perforated drip irrigation pipe 1 need to be dredged, the staff removes the connection joint 11 from the external delivery pipe, and connects one end of the traction rope 12 to the connecting traction ring 25. After the two side convex sealing discs 2 are inserted into the perforated drip irrigation pipe 1, the traction rope 12 is connected to the perforated drip irrigation pipe 1. The side convex plugging disc 2 is pulled to pass through the perforated drip irrigation pipe 1, and the water delivery tube 3 is synchronously injected into the two side convex plugging discs 2. With the help of the two separated side convex plugging discs 2, the limiting sealing ring 21 and the sealing sleeve 22 are used to intercept part of the space in the perforated drip irrigation pipe 1. The water delivery tube 3 is used to inject high-pressure water into the perforated drip irrigation pipe 1 at the corresponding positions of the two side convex plugging discs 2. The openings on the side wall of the perforated drip irrigation pipe 1 can be cleared with the help of the high-pressure water. When the side convex plugging disc 2 moves forward under the traction of the traction rope 12 , the boss shape of the side convex plugging disc 2 is used to limit the position of the limiting sealing ring 21, and the limiting sealing ring 21 and the sealing sleeve 22 will not be out of contact with the side convex plugging disc 2, which can effectively seal the gap between the side convex plugging disc 2 and the inner wall of the perforated drip irrigation pipe 1. After the dredging is completed, the side convex plugging disc 2 is taken out and the traction rope 12 is reset. During the dredging process, when the traction rope 12 breaks, the staff pulls the water delivery capillary 3 to drive the side convex plugging disc 2 to move in the opposite direction, and the limiting sealing ring 21 and the sealing sleeve 22 are under the action of resistance. The side convex sealing disc 2 is detached from the outer wall of the side convex sealing disc 2 and is pulled by the side convex sealing disc 2 and the pulling rope 26 to move. The limiting sealing ring 21 and the sealing sleeve 22 can be deformed after losing support, and a gap exists between the side convex sealing disc 2 and the perforated drip irrigation pipe 1, which effectively reduces the resistance encountered by the side convex sealing disc 2 when it is pulled out in the reverse direction, so that the side convex sealing disc 2 can be smoothly taken out from the perforated drip irrigation pipe 1, avoiding the side convex sealing disc 2, the limiting sealing ring 21 and the sealing sleeve 22 remaining in the perforated drip irrigation pipe 1, causing the perforated drip irrigation pipe 1 to be blocked and scrapped.

[0020] The diameter of the convex plugging disc 2 is smaller than that of the perforated drip irrigation pipe 1, and the limit sealing ring 21 and the sealing sleeve 22 are in contact with the inner wall of the perforated drip irrigation pipe 1; the diameter of the convex plugging disc 2 is even smaller, so that there is a gap between the outer wall of the convex plugging disc 2 and the inner wall of the perforated drip irrigation pipe 1, enabling the convex plugging disc 2 to be smoothly withdrawn from the perforated drip irrigation pipe 1.

[0021] A connection traction ring 25 is fixedly connected to one side of another convex plugging disc 2, and the traction rope 12 is tied to the connection traction ring 25; by providing the connection traction ring 25, it is convenient to connect the convex plugging disc 2 with the traction rope 12, enabling the traction rope 12 to pull the convex plugging disc 2 to move.

[0022] Two pulling ropes 26 are fixedly connected to the side wall of the limit sealing ring 21, and the other ends of the pulling ropes 26 are fixedly connected to the convex plugging disc 2; by providing the pulling ropes 26, the limit sealing ring 21 can be pulled to move when the convex plugging disc 2 moves in the reverse direction, preventing the limit sealing ring 21 and the sealing sleeve 22 from remaining in the perforated drip irrigation pipe 1.

[0023] A clamping convex block 27 is fixedly connected to one side of the convex plugging disc 2, and an inner concave clamping groove 28 is formed on one side of the limit sealing ring 21. The clamping convex block 27 is inserted into the inner concave clamping groove 28; by providing the clamping convex block 27 and the inner concave clamping groove 28, the limit sealing ring 21 can be installed on the convex plugging disc 2, preventing the limit sealing ring 21 and the sealing sleeve 22 from falling off the convex plugging disc 2 randomly. Moreover, the connection strength between the clamping convex block 27 and the inner concave clamping groove 28 is low, so that when the convex plugging disc 2 moves in the reverse direction, the limit sealing ring 21 and the sealing sleeve 22 can be detached from the convex plugging disc 2 under the resistance between them and the inner wall of the perforated drip irrigation pipe 1.

[0024] Working principle and usage process of the utility model: When performing normal irrigation operations, the towing rope 12 passes through the perforated drip irrigation pipe 1 and is connected to two connecting joints 11. The connecting joints 11 are connected to the external water conveyance pipe. The water body performs drip irrigation on the plants through the perforations on the perforated drip irrigation pipe 1. When it is necessary to dredge the perforations on the perforated drip irrigation pipe 1, the staff removes the connecting joint 11 from the external water conveyance pipe, connects one end of the towing rope 12 to the connecting towing ring 25. After inserting the two side convex plugging discs 2 into the perforated drip irrigation pipe 1, the side convex plugging discs 2 are towed to move inside the perforated drip irrigation pipe 1 through the towing rope 12. The water conveyance thin pipe 3 simultaneously injects water into the two side convex plugging discs 2. The two separated side convex plugging discs 2 cooperate with the limit sealing ring 21 and the sealing sleeve 22 to intercept a partial space inside the perforated drip irrigation pipe 1, and cooperate with the water conveyance thin pipe 3 to inject high-pressure water body into the perforated drip irrigation pipe 1 at the corresponding positions of the two side convex plugging discs 2, so as to dredge and clean the openings on the side wall of the perforated drip irrigation pipe 1 by means of the high-pressure water body. After the dredging is completed, the side convex plugging discs 2 are taken out and the towing rope 12 is reset. During the dredging process, when the towing rope 12 breaks, the staff tow the water conveyance thin pipe 3 to drive the side convex plugging discs 2 to move in the reverse direction. The limit sealing ring 21 and the sealing sleeve 22 are separated from the outer wall of the side convex plugging discs 2 under the action of resistance and are towed to move by the cooperation of the side convex plugging discs 2 and the pulling rope 26, effectively reducing the resistance suffered by the side convex plugging discs 2 when being pulled out in the reverse direction, and the side convex plugging discs 2 can be smoothly taken out from the perforated drip irrigation pipe 1.
