Description

Technical Field

[0001] The present invention relates to the technical field of irrigation equipment, in particular to an overhead irrigation equipment pipeline and a use method thereof. Background Art

[0002] A technical measure to replenish the water needed by crops. To ensure normal crop growth and high and stable yields, crops must be supplied with sufficient water. Under natural conditions, insufficient or unevenly distributed precipitation often fails to meet crop water requirements. Therefore, artificial irrigation is necessary to supplement the insufficient natural rainfall. Irrigation, or watering the land, requires water. The principle of irrigation is that the amount, frequency, and timing of irrigation should be determined based on the water requirements of the medicinal plant, its growth stage, climate, and soil conditions. Irrigation should be timely, appropriate, and appropriate. Types of irrigation include pre-sowing irrigation, seedling-stimulating irrigation, irrigation during the growing season, and winter irrigation. Sprinklers are commonly used irrigation machines. Sprinklers are farmland irrigation equipment that sprays pressurized water through nozzles into the air, scattering it onto the fields and crops as raindrops. Irrigation water can be pressurized by a pump or by utilizing the natural head of a higher water source. Sprinkler irrigation systems that use pumps for pressurization consist of a power machine, a water pump, water pipes, and sprinkler heads. Sprinkler irrigation systems that utilize natural head do not require a power machine or pump.

[0003] When irrigation equipment is used to irrigate crops, it needs to be connected to a longer and thicker water pipe. When the irrigation equipment is moved, the water pipe will move with the equipment, causing dragging. The dragged water pipe will roll in an irregular shape, causing the crops on both sides of the field to be crushed. The crushed crops will not continue to grow. Summary of the Invention

[0004] The problem to be solved by the present invention is that the irrigation machine pipe is dragged on the ground and causes damage to crops due to crushing.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: an overhead irrigation equipment pipeline and a method of using the same, comprising a T-tube, both sides of the T-tube are provided with a connecting structure, the bottom of the T-tube is provided with a connecting pipe, the surface of the connecting pipe is provided with atomizing heads in a circumferential array at equal intervals, the atomizing heads are embedded in the connecting pipe, the bottom of the connecting pipe is provided with a threaded rod, and the bottom of the threaded rod is provided with a fixing structure.

[0006] Preferably, the interior of the connecting pipe is hollow, a water-stop sleeve is slidably provided on the top of the connecting pipe, a limiting screw is provided on the top of the front of the water-stop sleeve, and the water-stop sleeve is adapted to the atomizing head.

[0007] Preferably, the connection structure includes a fixing frame, a filter tube, a fixing tube, a connecting flange, a base, a knob and a clamping plate, and both sides of the T-shaped tube are fixedly connected with a fixing tube.

[0008] Preferably, a connecting flange is provided on one side of the fixed pipe, bolts are installed in a circular array around the connecting flange at equal intervals, and a filter tube is fixedly connected to one side of the connecting flange, and the body of the filter tube is a rubber hose.

[0009] Preferably, a base is provided at the bottom of one side of the connecting flange, and fixing frames are provided on the front and rear sides of the top of the base. Bolts are passed through the front and rear sides of the bottom of the base, and the bolts are threadedly connected to the bottom of the fixing frame. A knob is passed through the top of one side of the fixing frame, and a splint is provided on one side of the knob, and the splint can move horizontally.

[0010] Preferably, the fixing structure includes a movable ring, a base plate, a ground plug, a fixing screw, a sleeve, a limit plate, an auxiliary thorn and a rotating shaft. The top of the sleeve is provided with a thread, the sleeve is adapted to the threaded rod, and the bottom of the sleeve is provided with a base plate.

[0011] Preferably, the bottom plate is provided with limit plates in a circular array at equal intervals around the bottom plate, and the top of the limit plates is provided with limit holes, and the limit plates are circular.

[0012] Preferably, a movable ring is slidably provided on the sleeve, a fixing screw is passed through the front of the movable ring, and a plurality of rotating shafts are equidistantly provided on the bottom of the movable ring surface in a circular array.

[0013] Preferably, an auxiliary thorn is rotatably provided at the bottom of the rotating shaft, and the auxiliary thorn is cylindrical, and the bottom of the auxiliary thorn passes through the limiting hole and extends to the outside of the limiting hole.

[0014] S1: When using, first fix the bottom plate on the land where the water pipe needs to pass. When fixing, first align the ground plug with the soil, then insert it forcefully. After inserting, rotate the fixing screw to loosen it. After loosening, pull the movable ring downward with your hand. The movable ring will drive the rotating shaft to move downward. When the rotating shaft moves downward, it will drive the auxiliary spike to move downward and insert it into the soil. Then tighten the fixing screw again. When inserting, it can only be opened and closed to a certain distance due to the limit of the upper limit hole of the limit plate. In this way, the auxiliary spike and the ground plug will increase its contact area with the ground, making it more stable. When recovering it later, you only need to loosen the fixing screw and move the movable ring upward to retract the auxiliary spike.

[0015] S2: After fixing the base plate and the sleeve, you can rotate the connecting pipe through the threaded rod at the bottom and insert it into the sleeve. You can freely adjust the height of the connecting pipe according to actual needs. After adjustment, you can rotate and loosen the limit screw. After loosening, move the water stop sleeve upward. After moving to a certain position, you can retighten the limit screw to fix it. The upward movement of the water stop sleeve will expose the atomizer heads on the connecting pipe. The more the water stop sleeve moves, the more atomizer heads are exposed. During irrigation in the later stage, the atomizer heads will be connected to the water pipe to atomize water to the surrounding crops.

[0016] S3: Finally, connect the moving water pipe on the irrigation equipment to the filter pipe. After the water pipe is connected, the water pipe will be suspended in the air and will not press on the crops on the land. After the water flows through the water pipe, it will be irrigated through the T-tube. After the water passes through the T-tube, the atomizing head will start to spray water in all directions. The filter pipe can be disassembled and replaced by tightening the bolts on the connecting flange. It can be replaced at any time after long-term use or when damaged. If you need to control the water pressure and water flow, you can also do it by rotating the knob. The knob will drive the splint to move to one side. The two splints will move toward each other and squeeze the body of the filter pipe. The water pressure and water flow can be changed by squeezing.

[0017] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0018] (1) A connection structure is provided on both sides of the T-tube. The connection structure can connect, filter and control the water pipe through the cooperation between the filter pipe and the clamp. The filter pipe can connect the water pipe and perform a preliminary filtration on the water flow. After a long period of filtration, it can be replaced and maintained by cooperating with the connecting flange to avoid a lot of debris inside the filter pipe after long-term use, which affects the passage of water flow. The replacement method is simple and convenient. The body of the filter pipe is relatively soft and can be clamped by the opposite movement of the clamp to control the water flow speed. It can be freely adjusted according to actual use needs, thereby increasing the adaptability and adjustability of the entire device. The water flow control speed can change the overall water delivery speed of the water pipe. The adjustment of the clamp is also very simple. It only requires rotating two knobs to clamp and move.

[0019] (2) A connecting pipe is provided at the bottom of the T-shaped pipe, which can raise the water pipe as a whole. After the water pipe is raised, it will be suspended in the air from the ground, reducing the pressure on the crops. In addition, an embedded atomizing head and a water stop sleeve are provided on the connecting pipe. After the water flows through the T-shaped pipe, the atomizing nozzle sprays water outward to irrigate a small area of ​​crops around the connecting pipe. Irrigation needs can also be selected according to actual conditions. If irrigation is not required, the water stop sleeve can be used to control the opening and closing of the water pipe. Since there are several atomizing heads, the amount of atomization can also be controlled by the water stop sleeve.

[0020] (3) A fixing structure is provided at the bottom of the connecting pipe. The fixing structure can support and fix the connecting pipe as a whole through the cooperation between the ground plug and the auxiliary spike. The traditional ground plug is fixed by one spike. If there is a lateral force after it is inserted into the soil, it will cause instability and tilt and fall. The auxiliary spike can cooperate with the movable ring and penetrate the ground in a spread-out manner when it moves downward. In this way, the auxiliary spike can increase the area of ​​the ground spike when it is inserted into the soil, making the ground spike more stable. Even if it is subjected to a strong lateral force, it will not tilt. The insertion and recovery of the auxiliary spike are relatively simple and convenient, and will not take up too much of the user's operating time. The practicality of the ground spike combined with the auxiliary spike can also be applied to relatively bumpy land, increasing the overall environmental selectivity of the device, and making the user more worry-free when installing the ground spike.

[0042] S1: When in use, first fix the bottom plate 702 on the land where the water pipe needs to pass. When fixing, first align the ground plug 703 with the soil, and then insert it with force. After inserting, rotate the fixing screw 704 to loosen it. After loosening, pull the movable ring 701 downward by hand. The movable ring 701 will drive the rotating shaft 708 to move downward. When the rotating shaft 708 moves downward, it will drive the auxiliary thorn 707 to move downward and insert it into the soil. Then tighten the fixing screw 704 again. When inserting, it can only be opened and closed to a certain distance due to the limit of the upper limit hole of the limiting plate 706. In this way, the auxiliary thorn 707 cooperates with the ground plug 703 to increase its contact area with the ground, making it more stable. When recovering it later, you only need to loosen the fixing screw 704 and move the movable ring 701 upward to retract the auxiliary thorn 707;

[0043] S2: After fixing the bottom plate 702 and the sleeve 705, the connecting pipe 3 can be rotated and inserted into the sleeve 705 through the threaded rod 6 at the bottom. The height of the connecting pipe 3 can be freely adjusted according to actual use needs. After adjustment, the limit screw 8 can be rotated and loosened. After loosening, the water-stop sleeve 4 is moved upward. After moving to a certain position, the limit screw 8 can be tightened again to fix it. The upward movement of the water-stop sleeve 4 will expose the atomizing head 5 on the connecting pipe 3. The more the water-stop sleeve 4 moves, the more exposed the atomizing heads 5 are. During the later irrigation, the atomizing heads 5 will be connected to the water pipe to atomize water to the surrounding crops.

[0044] S3: Finally, connect the movable water pipe on the irrigation equipment to the filter pipe 202. After the water pipe is connected, the water pipe will not press on the crops on the land because the height of the connecting pipe 3 is suspended. After the water flows into the water pipe, it will be irrigated through the T-tube 1. After the water passes through the T-tube 1, the atomizing head 5 will start to spray water in all directions. The filter pipe 202 can be disassembled and replaced by tightening the bolts on the connecting flange 204. It can be replaced at any time after long-term use or when damaged. If you need to control the water pressure and water flow, you can also rotate the knob 206. The knob 206 will drive the splint 207 to move to one side. The two splints 207 move toward each other to squeeze the body of the filter pipe 202. The water pressure and water flow can be changed by squeezing.

[0045] The working principle and use process of the present invention are as follows: when using, the user first fixes the bottom plate 702 on the land where the water pipe needs to pass, and when fixing, first aligns the ground plug 703 with the soil, and then inserts it with force. After inserting, rotate the fixing screw 704 to loosen it, and then pull the movable ring 701 downward by hand. The movable ring 701 will drive the rotating shaft 708 to move downward. When the rotating shaft 708 moves downward, it will drive the auxiliary thorn 707 to move downward and insert it into the soil. Then tighten the fixing screw 704 again. When inserting, it will be limited by the upper limit hole of the limit plate 706. The position can only be opened and closed to a certain distance, so that the auxiliary thorn 707 cooperates with the ground plug 703 to increase its contact area with the ground, making it more stable. During subsequent recovery, it is only necessary to loosen the fixing screw 704 and move the movable ring 701 upwards to retract the auxiliary thorn 707. After fixing the bottom plate 702 and the sleeve 705, the connecting pipe 3 can be rotated and inserted into the sleeve 705 through the threaded rod 6 at the bottom. The height of the connecting pipe 3 can be freely adjusted according to actual use needs. After adjustment, the limit screw 8 can be rotated and loosened. After loosening, the water stop sleeve 4 moves upward, and after moving to a certain position, the limit screw 8 can be tightened again to fix it. The upward movement of the water stop sleeve 4 will expose the atomizing head 5 on the connecting pipe 3. The more the water stop sleeve 4 moves, the more exposed the atomizing heads 5 are. During the later irrigation, the atomizing heads 5 will be connected to the water pipe to atomize water to the crops around. Finally, the water pipe moving on the irrigation equipment is connected to the filter pipe 202. After the water pipe is connected, the water pipe will not press on the crops on the land because the height of the connecting pipe 3 is suspended. After the water is passed through the water pipe, it will pass through The T-tube 1 is used for irrigation. After the water passes through the T-tube 1, the atomizing head 5 will start to spray water in the surrounding area. The filter tube 202 can be disassembled and replaced by loosening the connecting flange 204 with the bolts. It can be replaced at any time after long-term use or when it is damaged. If the water pressure and water flow need to be controlled, it can be done by rotating the knob 206. The knob 206 will drive the splint 207 to move to one side. The two splints 207 will move toward each other to squeeze the body of the filter tube 202. The water pressure and water flow can be changed by squeezing.
