[0002] Drip irrigation tape, used in water conservancy irrigation, is a water-saving irrigation device. It is usually a strip of plastic hose with drippers of a specific structure on its inner or outer wall. Water is dripped evenly and slowly into the soil near the crop roots through the drippers. The water flow of the drip irrigation tape can directly act on the crop root zone, which can reduce water evaporation and leakage, improve water resource utilization, and is suitable for various terrains and crops. It is especially widely used in arid and water-scarce areas and in the cultivation of high-value-added crops, which can achieve precision irrigation and help crop growth.

[0003] Existing technologies often have the following problems when used:

[0004] Currently, in the process of laying drip irrigation tape in water conservancy irrigation, the tape cannot be disassembled and reassembled after the tape is laid in stages, making it inconvenient to quickly replenish the tape and affecting the overall laying efficiency. Furthermore, it is difficult to ensure the flatness and accuracy of the tape during the laying process, which can easily lead to problems such as tape deviation or even tangling, resulting in poor laying effect and thus affecting the irrigation effect. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a drip irrigation tape laying bracket for water conservancy irrigation. It can effectively solve the problems in the existing technology that the drip irrigation tape cannot be disassembled and reassembled after the drip irrigation tape is laid in stages, which affects the overall laying efficiency of the drip irrigation tape, and that it is difficult to ensure the flatness and accuracy of the drip irrigation tape during the laying process, resulting in poor laying effect of the drip irrigation tape and affecting the irrigation effect of the drip irrigation tape.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a support frame for laying drip irrigation tape for water conservancy irrigation, including:

[0008] The take-up and unwinding roller has a hollow structure and a central shaft is fixedly connected to its inner side.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: Refer to Figures 1 to 3 The support frame for laying drip irrigation tape for water conservancy irrigation includes:

[0028] The assembly includes a take-up and unwinding roller 1, two moving wheels 3, and a high-efficiency laying component. The take-up and unwinding roller 1 has a hollow structure and a central shaft 2 is fixedly connected to its inner side. Lateral protective discs 18 are fixedly connected to both ends of the take-up and unwinding roller 1. Axles 4 are fixedly connected to the middle of each of the two moving wheels 3, and the two axles 4 are selectively fixedly connected to the central shaft 2. The high-efficiency laying component includes two No. 1 bearings 5 ​​fixedly connected to the outer peripheral walls of the two axles 4. Support frames 6 are fixedly connected to the outer rings of the two No. 1 bearings 5, and push rods 7 are fixedly connected to the ends of the two support frames 6 away from the axles 4.

[0029] The drip irrigation tape is wound onto the take-up and release roller 1, and then the central shaft 2 is connected and fixed to the two wheel shafts 4. One end of the drip irrigation tape is passed between the two limit wheels 17. The operator holds the push rod 7 and pushes the bracket to move in the area where the drip irrigation tape needs to be laid. When the moving wheel 3 rolls relative to the ground, it can drive the entire bracket forward. At the same time, the take-up and release roller 1 can rotate continuously with the rolling of the moving wheel 3 so as to automatically release the drip irrigation tape gradually.

[0030] Specifically, the support frame 6 is rotatably connected to the wheel axle 4 via the first bearing 5. Therefore, when the push rod 7 and the support frame 6 are pushed, the support frame 6 will not obstruct the rotation of the wheel axle 4, so as to ensure the stable movement of the bracket and the moving wheel 3.

[0031] Two quick-release components are fixedly connected to the axial sidewall of the central shaft 2. The quick-release components are used to quickly connect, fix and disassemble the central shaft 2 and the wheel axle 4. The quick-release components include a connecting block 8 fixedly connected to the axial sidewall of the central shaft 2, a mating groove 9 is opened on the axial sidewall of the wheel axle 4, the connecting block 8 matches the mating groove 9, a fastening screw 10 is threadedly connected to the outer peripheral wall of the wheel axle 4, a disassembly knob 19 is fixedly connected to the end of the fastening screw 10 away from the wheel axle 4, and a screw hole 11 is opened in the middle of the connecting block 8, the fastening screw 10 is threadedly engaged with the screw hole 11.

[0032] Connect the connecting block 8 on the central shaft 2 into the mating groove 9 on the wheel axle 4. Then, rotate the disassembly knob 19 to drive the fastening screw 10 to rotate, so that the fastening screw 10 engages with the screw hole 11 in the middle of the connecting block 8, so as to securely connect the wheel axle 4 and the central shaft 2. When it is necessary to replenish the drip irrigation tape to continue laying, the fastening screw 10 can be driven to rotate in the opposite direction to release the connection between the central shaft 2 and the wheel axle 4, and the take-up and unwinding roller 1 with the drip irrigation tape can be reinstalled. By realizing the disassembly and assembly function of the take-up and unwinding roller 1, the drip irrigation tape can be replenished conveniently and quickly, which is conducive to improving the overall laying efficiency of the drip irrigation tape.

[0033] Specifically, the outer surface of the movable wheel 3 is provided with anti-slip diagonal texture, which can provide sufficient friction when the movable wheel 3 rolls relative to the ground, so as to ensure that the winding roller 1 can rotate stably when the support moves, so that the drip irrigation tape can be released and laid smoothly.

[0034] A winding limit assembly is fixedly connected to the outer peripheral wall of the central shaft 2. The winding limit assembly is used to limit the winding and laying of the drip irrigation tape. The winding limit assembly includes two No. 2 bearings 12 fixedly connected to the outer peripheral wall of the central shaft 2. Vertical plates 13 are fixedly connected to the outer rings of the two No. 2 bearings 12. Counterweights 14 are fixedly connected to the outer walls of the two vertical plates 13. Legs 15 are fixedly connected to the lower position of the outer walls of the two vertical plates 13. Low-speed motors 16 are fixedly installed at the close ends of the two legs 15. Limiting wheels 17 are fixedly connected to the output ends of the two low-speed motors 16. The limiting wheels 17 adopt a concave structure and a silicone rubber pad is fixedly connected to the outer surface of the limiting wheels 17.

[0035] When the moving wheel 3 rolls relative to the ground, it can drive the take-up and unwinding roller 1 to rotate synchronously. At this time, two low-speed motors 16 can be started. The two low-speed motors 16 drive the two limit wheels 17 to rotate in opposite directions at an appropriate speed, so as to control the unwinding and laying speed of the drip irrigation tape. At the same time, the concave structure of the two limit wheels 17 and the silicone rubber pad can be used to limit the laying of the drip irrigation tape, effectively preventing the drip irrigation tape from shifting or falling off during the laying process, and ensuring the laying effect and irrigation effect of the drip irrigation tape.

[0036] Specifically, when the central shaft 2 rotates, since the vertical plate 13 is rotatably connected to the central shaft 2 through the No. 2 bearing 12, and the outer wall of the vertical plate 13 is fixed with a counterweight 14, the gravity of the counterweight 14 can be used to keep the vertical plate 13 perpendicular to the ground. This allows the two legs 15 and the two limit wheels 17 to always be below the take-up and unwinding rollers 1 when the central shaft 2 rotates, thus ensuring the normal operation of the unwinding limit assembly.

[0037] Specifically, the low-speed motor 16 is a three-phase asynchronous low-speed motor of model YE3-90S-4, and the two low-speed motors 16 are externally connected to a control circuit equipped with a time relay to ensure that the two low-speed motors 16 can drive the two limit wheels 17 to rotate in opposite directions at synchronous speed, thus ensuring the stability of the drip irrigation tape laying.

[0038] The working principle of this utility model is as follows:

[0039] In use, first wind the drip irrigation tape onto the take-up and release roller 1, then connect and fix the central shaft 2 to the two wheel axles 4, and let one end of the drip irrigation tape pass between the two limit wheels 17. The operator holds the push rod 7 and pushes the bracket to move in the area where the drip irrigation tape needs to be laid. When the moving wheel 3 rolls relative to the ground, it can drive the entire bracket forward. At the same time, the take-up and release roller 1 can rotate continuously with the rolling of the moving wheel 3 so as to automatically release the drip irrigation tape gradually.

[0040] During the installation of the take-up and unwinding roller 1 onto the bracket, the connecting block 8 on the central shaft 2 is first inserted into the mating groove 9 on the wheel axle 4. Then, the fastening screw 10 is rotated by rotating the disassembly and assembly knob 19, so that the fastening screw 10 is threaded into the screw hole 11 in the middle of the connecting block 8, so as to securely connect the wheel axle 4 and the central shaft 2. When it is necessary to replenish the drip irrigation tape to continue laying, the fastening screw 10 can be driven to rotate in the opposite direction to release the connection between the central shaft 2 and the wheel axle 4, and the take-up and unwinding roller 1 with the drip irrigation tape can be reinstalled. By realizing the disassembly and assembly function of the take-up and unwinding roller 1, the drip irrigation tape can be replenished conveniently and quickly, which is conducive to improving the overall laying efficiency of the drip irrigation tape.

[0041] During the drip irrigation tape laying process, when the moving wheel 3 rolls relative to the ground, it can drive the take-up and unwinding roller 1 to rotate synchronously. At this time, two low-speed motors 16 can be started, and the two low-speed motors 16 can drive the two limiting wheels 17 to rotate in opposite directions at an appropriate speed, so as to control the unwinding and laying speed of the drip irrigation tape. At the same time, the concave structure of the two limiting wheels 17 and the silicone rubber pad can be used to limit the laying of the drip irrigation tape, effectively preventing the drip irrigation tape from shifting or falling off during the laying process, and ensuring the laying effect and irrigation effect of the drip irrigation tape.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
