Description

Rollers for drip irrigation tape laying machine Technical Field

[0001] This utility model relates to the technical field of drip irrigation tape laying machine rollers, specifically to rollers for drip irrigation tape laying machines used in water conservancy irrigation. Background Technology

[0002] A drip irrigation tape laying machine is a specialized agricultural machine used in modern agricultural water-saving irrigation. It is mainly used to efficiently lay drip irrigation tape in planting areas such as farmland, orchards, and vegetable gardens to achieve the goals of precision irrigation and water conservation.

[0003] This equipment typically consists of a traction device, a drip irrigation tape roll placement frame, a laying guide mechanism, and a soil covering and compaction component. It can be used with tractors and other power machinery. Through mechanical transmission or hydraulic control, the rolled drip irrigation tape is automatically unfolded and laid on the ground or shallowly buried in the soil at a set spacing and depth during the journey. At the same time, it completes the positioning and fixation of the drip irrigation tape, preventing displacement or damage caused by factors such as wind and water flow.

[0004] However, in existing drip irrigation tape laying machine rollers, the rollers are usually designed to be fixed. When facing pipes with larger diameters, this fixed roller design restricts the pipe's adaptability, making it difficult for large-diameter pipes to pass through the roller structure smoothly. This limits the application of large-specification pipes in drip irrigation tape laying scenarios and fails to meet the diverse needs of irrigation pipe laying. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a roller for a drip irrigation tape laying machine for water conservancy irrigation, which can effectively solve the problem that the fixed rollers in the existing technology restrict the adaptability of the pipeline.

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

[0007] This utility model provides a roller for a drip irrigation tape laying machine for water conservancy irrigation, including: a mounting column, a laying component installed on the side wall of the mounting column, the laying component including a shell and a mounting block installed on one side of the mounting column, a rotating roller rotatably connected inside the shell, and an elastic component provided between the rotating roller and the shell;

[0008] The elastic component includes an elastic groove formed in the inner wall of the housing, a slider slidably connected in the elastic groove, the slider and the elastic groove being connected by a No. 1 spring, a rotating rod being connected to one side of the slider, and the housing and the mounting column being connected by a fixing component.

[0009] The fixing component includes a fixing groove, in which a fixing plug plate is slidably connected. The fixing plug plate is inserted into a slot, which is located on one side of the mounting block.

[0010] According to the rollers of the drip irrigation tape laying machine for water conservancy irrigation described above, an installation groove is provided in the installation column, and the installation block is slidably connected in the installation groove. The installation block is fixedly connected to one side of the outer shell.

[0011] The slider has a rotating groove, and a rotating column is rotatably connected in the rotating groove. The rotating column is fixedly connected to one side of the rotating roller.

[0012] A cross plate is fixedly connected to one side of the fixed plug plate. The cross plate is slidably connected to the cross rotation, which is located inside the mounting column.

[0013] A handle is fixedly connected to the other end of the cross plate.

[0014] The cross rotation and the cross plate are connected by a second spring.

[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0016] This invention solves the problems of fixed roller positions and limited compatibility with pipe sizes in existing drip irrigation tape laying machines. The elastic component utilizes a combination of a spring and a slider to allow the rotating roller to expand and move elastically with the pipe diameter, preventing pipe damage from compression while maintaining guiding and compaction functions. The fixing component, through an adjustable plug-in structure and spring reset design, allows for quick adjustment and locking of the outer shell position, adapting to different pipe size requirements. This achieves compatibility with large-diameter and diverse pipes, improving the flexibility, stability, and installation efficiency of drip irrigation tape laying, reducing pipe friction damage, ensuring irrigation uniformity, and is suitable for various terrains and pipe materials.

[0024] 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.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example: Referring to Figures 1 to 5, the roller of the drip irrigation tape laying machine for water conservancy irrigation includes: a mounting column 1, a laying component 2 installed on the side wall of the mounting column 1, the laying component 2 includes a housing 21 and a mounting block 24 installed on one side of the mounting column 1, a rotating roller 22 rotatably connected inside the housing 21, and an elastic component 3 provided between the rotating roller 22 and the housing 21.

[0027] The elastic component 3 includes an elastic groove 31 formed in the inner wall of the outer shell 21, a slider 33 is slidably connected in the elastic groove 31, the slider 33 and the elastic groove 31 are connected by a spring 32, a rotating rod 22 is connected to one side of the slider 33, and the outer shell 21 and the mounting column 1 are connected by a fixing component 4.

[0028] The fixing component 4 includes a fixing groove 41, in which a fixing plug plate 42 is slidably connected. The fixing plug plate 42 is inserted into a slot 43, which is located on one side of the mounting block 24.

[0029] The mounting column 1 has a mounting groove 23, and a mounting block 24 is slidably connected in the mounting groove 23. The mounting block 24 is fixedly connected to one side of the outer shell 21.

[0030] The slider 33 has a rotating groove 34, and a rotating column 35 is rotatably connected in the rotating groove 34. The rotating column 35 is fixedly connected to one side of the rotating roller 22.

[0031] A cross plate 45 is fixedly connected to one side of the fixed plug plate 42. The cross plate 45 is slidably connected inside the cross rotation 44, which is located inside the mounting column 1.

[0032] A handle 47 is fixedly connected to the other end of the cross plate 45.

[0033] The cross rotation 44 and the cross plate 45 are connected by a second spring 46.

[0034] The design of the elastic component 3 solves the problem of the fixed roller restricting large-diameter pipes. When laying drip irrigation pipes of different diameters, the expansion of the pipe will compress the rotating roller 22. At this time, the slider 33 compresses the first spring 32 in the elastic groove 31, causing the rotating roller 22 to slide outward, dynamically expanding the space for the pipe to pass through. For example, when a larger diameter pipe passes through, the rotating roller 22 can move laterally within the spring force range, avoiding pipe compression deformation or jamming due to rigid limitation. At the same time, the rotating groove 34 in the slider 33 cooperates with the rotating column 35 to ensure that the rotating roller 22 can still rotate freely during elastic movement, maintaining the guiding and compaction function for the pipe. This elastic buffering mechanism not only accommodates the laying requirements of pipes of different specifications, but also maintains appropriate pressure on the pipe through the spring rebound force, preventing the pipe from being suspended or deviated. It can reduce laying errors through elastic self-adaptation, improve the adhesion between the drip irrigation tape and the soil, and ensure irrigation uniformity. In addition, the flexible contact design of the elastic component 3 can also reduce frictional damage between the pipe and the roller, extend the service life of the pipe, and is suitable for laying drip irrigation tape of various materials.

[0035] The design of the fixing component 4 enables flexible positioning and rapid fixing of the laying component 2, enhancing the equipment's adaptability to different pipe sizes. During installation, pulling the handle 47 causes the cross plate 45 to compress the second spring 46, disengaging the fixing plug plate 42 from the slot 43. At this time, the outer shell 21 slides up and down within the mounting groove 23 via the mounting block 24, allowing the relative position of the outer shell 21 and the mounting column 1 to be pre-adjusted according to the pipe diameter, thus widening or narrowing the gap between the rotating roller 22 and the column. For example, when laying a large-diameter pipe, the outer shell 21 is adjusted downwards to increase the space; when laying a small-diameter pipe, it is adjusted upwards to tighten the gap. After adjustment, releasing the handle 47 causes the second spring 46 to push the cross plate 45 back to its original position, and the fixing plug plate 42 is inserted into the slot 43 to lock in place, ensuring that the outer shell 21 will not shift due to vibration or traction during the laying process. This modular design not only supports rapid on-site adjustment but also facilitates disassembly and maintenance, such as replacing rotating rollers 22 of different specifications or cleaning debris entangled on the rollers. Meanwhile, the design of the cross plate 45 and the cross rotation groove 44 improves the stability of the connection structure by limiting the rotation direction of the plug plate, avoiding the loosening problem that may occur with traditional bolt fixing methods. It is especially suitable for long-term operation in complex farmland terrain, ensuring laying accuracy and equipment reliability.

[0036] The working principle of this utility model is as follows:

[0037] When in use, the pipe is passed through the gap between the mounting column 1 and the rotating roller 22. When water is supplied into the pipe, the pipe begins to expand under the action of the water flow. For pipes with larger diameters, the pipe continuously presses against the rotating roller 22 during the expansion process. Because the rotating roller 22 can slide left and right within a certain range due to the design of the slider 33 and the first spring 32, as the pipe continues to expand, the pipe will squeeze the rotating roller 22 and drive it to slide outward, thereby increasing the reserved space and ensuring the normal use of the pipe.

[0038] When installing the laying component 2, the installation position of the laying component 2 can be controlled by the design of the fixing component 4. This design also allows the laying component 2 to be quickly disassembled at any time. During installation, first pull the handle 47 to slide it outward. At this time, the mounting block 24 with the slot 43 can move freely in the mounting slot 23. When it moves to the required installation position, release the handle 47. At this time, the fixing plug plate 42 slides to the right under the action of the second spring 46 and drives the fixing plug plate 42 to insert into the slot 43 of the mounting block 24, thereby fixing the laying component 2 and ensuring the stability of the device operation.

[0039] 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.
