Description

Technical Field

[0001] This utility model relates to the field of camellia oil cultivation technology, and more specifically, to a high-efficiency water-saving irrigation device for camellia oil cultivation. Background Technology

[0002] Camellia oleifera is a unique woody oilseed crop in my country. Its seeds can be pressed to extract tea oil, which is rich in unsaturated fatty acids and nutrients, possessing both economic and ecological benefits. Camellia oleifera cultivation is mainly distributed in the hilly and mountainous areas of southern China. It is sensitive to water requirements; because it is often planted on slopes with complex terrain and poor soil water retention, uneven spatial and temporal distribution of natural rainfall easily leads to seasonal drought, directly affecting flowering rate, fruit development, and oil quality. Therefore, artificial irrigation is necessary to meet the water requirements of Camellia oleifera.

[0003] However, the existing irrigation equipment has a limited range of irrigation, which means that only camellia trees in fixed locations can receive water. This requires the preparation of multiple irrigation devices, which not only increases the operating cost but also increases the utilization rate of water resources. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model proposes a high-efficiency water-saving irrigation device for camellia cultivation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency water-saving irrigation device for camellia cultivation, comprising a connecting pipe and a telescopic pipe, wherein the telescopic pipe is disposed inside the connecting pipe, a nozzle is installed at the top of the telescopic pipe, a pair of sliders are fixedly connected to the outside of the telescopic pipe, both of the sliders are slidably connected to the inside of the connecting pipe, an L-plate is fixedly connected to the outside of the connecting pipe, a motor is installed on the side of the L-plate near the telescopic pipe, and a reciprocating mechanism for raising and lowering the telescopic pipe is provided at the output end of the motor.

[0006] Furthermore, the reciprocating mechanism includes a turntable, a rotating rod, a ring plate, and a fixed rod. The turntable is connected to the output end of the motor. The rotating rod is located at the end of the turntable away from the motor. The ring plate is slidably connected to the outside of the rotating rod. The fixed rod is fixedly connected to the end away from the ring plate. The end of the fixed rod away from the ring plate is fixedly connected to the outside of the telescopic tube.

[0007] Furthermore, the turntable has four sets of threaded grooves at one end near the rotating rod, and the threaded grooves are threadedly connected to the rotating rod.

[0008] Furthermore, a corrugated pipe is glued to the outside of the telescopic tube, and the end of the corrugated pipe away from the telescopic tube is glued to the outside of the connecting tube.

[0009] Furthermore, an annular groove is provided on the outer side of the L-plate, and the annular groove is designed as a "groove".

[0010] The technical effects and advantages of this utility model of a high-efficiency water-saving irrigation device for camellia cultivation are as follows:

[0011] This invention utilizes a reciprocating mechanism driven by a motor to achieve dynamic vertical height adjustment of the sprinkler head. Combined with the gravity-spraying characteristics of the sprinkler head, it forms a near-far dual-domain irrigation coverage mode. During the rising phase, the sprinkler head expands the coverage radius through a parabolic trajectory, while during the descending phase, it precisely irrigates the near-end area. This breaks through the static limitations of traditional fixed spraying and simultaneously achieves wide-area uniform irrigation and intensive water resource utilization, significantly reducing the need for multiple equipment deployments.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 - Figure 4As shown, a high-efficiency water-saving irrigation device for camellia cultivation includes a connecting pipe 1 and a telescopic pipe 2. The telescopic pipe 2 is located inside the connecting pipe 1. A nozzle 3 is installed at the top of the telescopic pipe 2. A pair of sliders 4 are fixed to the outside of the telescopic pipe 2. Both sliders 4 are slidably connected to the inside of the connecting pipe 1. An L-plate 5 is fixed to the outside of the connecting pipe 1. A motor 6 is installed on the side of the L-plate 5 near the telescopic pipe 2. The output end of the motor 6 is provided with a reciprocating mechanism for raising and lowering the telescopic pipe 2.

[0021] Existing irrigation equipment has a limited irrigating range, resulting in only tea trees in fixed locations receiving water. This necessitates the use of multiple irrigation devices, increasing both operating costs and water utilization. In this invention, the connecting pipe 1 is buried underground, and its bottom end is connected to the outlet pipe. When water flows from the outlet pipe, it passes through the connecting pipe 1 into the telescopic pipe 2, and then from the telescopic pipe 2 into the nozzle 3, where it is sprayed in a circular pattern onto the surface of the tea trees. At this point, the motor 6 can be started. The motor 6 drives the reciprocating mechanism, which in turn drives the telescopic pipe 2 upwards. As the telescopic pipe 2 moves upward, the contact height between the nozzle 3 and the ground increases. At this time, the sprayed water source will move in a farther direction. Because the height of the nozzle 3 increases, the water source sprayed by the nozzle 3 will have a longer contact time with the ground under the action of gravity. This allows the water source to further increase the spraying distance and spray more camellia. When the telescopic pipe 2 descends, it can spray camellia closer through the nozzle 3. By adjusting the height of the telescopic pipe 2, the function of irrigating camellia at different distances can be achieved, effectively saving water. It should be noted that the nozzle 3 is existing technology and the technology is mature, so it will not be elaborated on further.

[0022] like Figure 1 - Figure 4 As shown, the reciprocating mechanism includes a turntable 7, a rotating rod 8, a ring plate 9, and a fixed rod 10. The turntable 7 is connected to the output end of the motor 6. The rotating rod 8 is located at the end of the turntable 7 away from the motor 6. The ring plate 9 is slidably connected to the outside of the rotating rod 8. The fixed rod 10 is fixedly connected to the end away from the ring plate 9. The end of the fixed rod 10 away from the ring plate 9 is fixedly connected to the outside of the telescopic tube 2.

[0023] When the motor 6 is running, it drives the turntable 7 to rotate. The rotation of the turntable 7 drives the rotating rod 8 to make a circular motion. When the rotating rod 8 is running, it squeezes the ring plate 9, causing the ring plate 9 to move. When the rotating rod 8 is displaced to the extreme position at the top, as the rotating rod 8 continues to run, it will squeeze the ring plate 9 to move downward, thereby achieving up-and-down reciprocating movement. The reciprocating movement of the ring plate 9 will drive the fixed rod 10 to reciprocate, thereby controlling the nozzle 3 to reciprocate in height.

[0024] like Figure 4As shown, the turntable 7 has four sets of threaded grooves 11 at one end near the rotating rod 8, and the threaded grooves 11 are threadedly connected to the rotating rod 8.

[0025] When it is necessary to increase the distance the nozzle 3 moves, simply rotate the rotating rod 8 in the opposite direction to disengage it from the innermost threaded groove 11 and move the rotating rod 8 to any of the other three sets of threaded grooves 11. Then rotate the rotating rod 8 to connect it with any of the other three sets of threaded grooves 11. At this time, as the rotating rod 8 rotates with the turntable 7, it will cause the ring plate 9 to move a greater distance.

[0026] like Figure 5 As shown, a corrugated pipe 12 is glued to the outside of the telescopic pipe 2, and the end of the corrugated pipe 12 away from the telescopic pipe 2 is glued to the outside of the connecting pipe 1.

[0027] To prevent water from seeping out through the connection between the connecting pipe 1 and the telescopic pipe 2, this invention uses a corrugated pipe 12 glued between the connecting pipe 1 and the telescopic pipe 2. The corrugated pipe 12 then wraps around the connection, preventing liquid from flowing out. Furthermore, the corrugated pipe 12 deforms as the telescopic pipe 2 moves up and down, providing it with room to move. It should be noted that the corrugated pipe 12 is existing technology and is mature; therefore, further explanation is unnecessary.

[0028] like Figure 1 As shown, an annular groove 13 is provided on the outer side of L plate 5, and the annular groove 13 is designed as a "groove".

[0029] The opening of the annular groove 13 can reduce the production cost of L plate 5.

[0030] Working principle: The connecting pipe 1 is buried underground, and its bottom end is connected to the water outlet pipe. When water comes out of the water outlet pipe, it enters the interior of the telescopic pipe 2 through the connecting pipe 1, and then enters the interior of the nozzle 3 through the telescopic pipe 2, spraying it in a circular pattern on the surface of the camellia. At this time, the motor 6 can be started. When the motor 6 runs, it drives the reciprocating mechanism, which in turn drives the telescopic pipe 2 to move up and down. When the telescopic pipe 2 moves upward, the contact height between the nozzle 3 and the ground increases. At this time, the sprayed water source will move in a farther direction. Because the height of the nozzle 3 increases, the water source sprayed by the nozzle 3 will have a longer contact time with the ground under the action of gravity. This allows the water source to further increase the spraying distance and spray the camellia further away. When the telescopic pipe 2 descends, it can spray the camellia closer through the nozzle 3. By adjusting the height of the telescopic pipe 2, the function of irrigating camellia at different distances can be realized, effectively saving water.

[0031] When the motor 6 is running, it will drive the turntable 7 to rotate. The rotation of the turntable 7 will drive the rotating rod 8 to make a circular motion. When the rotating rod 8 is running, it will squeeze the ring plate 9, causing the ring plate 9 to move. When the rotating rod 8 is displaced to the extreme position at the top, as the rotating rod 8 continues to run, it will squeeze the ring plate 9 to move downward, thereby achieving up and down reciprocating movement. The reciprocating movement of the ring plate 9 will drive the fixed rod 10 to reciprocate, thereby controlling the nozzle 3 to reciprocate in height.

[0032] When it is necessary to increase the distance the nozzle 3 moves, simply rotate the rotating rod 8 in the opposite direction to disengage it from the innermost threaded groove 11 and move the rotating rod 8 to any of the other three sets of threaded grooves 11. Then rotate the rotating rod 8 to connect it with any of the other three sets of threaded grooves 11. At this time, as the rotating rod 8 rotates with the turntable 7, it will cause the ring plate 9 to move a greater distance.

[0033] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
