Abstract
Description
Technical Field
[0001] This utility model relates to the field of cotton seedling planting technology, specifically a drip irrigation tape film laying guide device for cotton seedling planting. Background Technology
[0002] In order to improve water use efficiency, promote root development and reduce disease occurrence during cotton seedling planting, drip irrigation tape is usually laid as soon as possible after sowing. This ensures that the water and nutrient requirements of cotton during its growth process are met in a timely manner. At the same time, drip irrigation tape can precisely control water supply, ensure uniform water distribution, reduce evaporation and leakage, thereby improving water use efficiency. This technology is particularly suitable for arid and semi-arid regions and can significantly reduce water waste. During the laying of drip irrigation tape, a guiding device is required to prevent deviation and ensure the accuracy of the drip irrigation tape laying, avoiding positional shift.
[0003] Currently available drip irrigation tape laying guide devices for cotton seedling planting mainly rely on the constraint of guide tubes and nylon wheels to ensure precise laying of the drip irrigation tape along the planting row. However, when connecting the device to the drip irrigation tape, the narrow inlet of the guide tube and the blind spots that can easily occur during manual operation can lead to problems such as unsuccessful insertion and positioning difficulties during the introduction of the drip irrigation tape into the device, affecting the progress of subsequent drip irrigation tape laying. Therefore, a new drip irrigation tape laying guide device for cotton seedling planting is proposed to address these issues. Utility Model Content
[0004] The purpose of this invention is to provide a cotton seedling drip irrigation tape laying guide device to solve the problems mentioned in the background art, such as the failure to insert the drip irrigation tape on the first attempt and the difficulty in alignment when introducing the drip irrigation tape.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A cotton seedling drip irrigation tape film-laying guide device includes a guide sleeve. The top of the guide sleeve is connected to an auxiliary through-hole. A fixed inner inclined plate is fixedly connected to the right side of the auxiliary through-hole. A movable inner inclined plate is provided on the left side of the auxiliary through-hole. A support rod is fixedly connected to the bottom of both the movable and fixed inner inclined plates. A first guide wheel is sleeved on the outside of the middle of the support rod. A movable support rod that is slidably connected to the auxiliary through-hole is fixedly connected to the left side of the support rod connected to the movable inner inclined plate. A connecting rod is fixedly connected between the front and rear movable support rods. A guide rod passes through the middle of the connecting rod. A chuck is fixedly connected to the side of the guide rod away from the auxiliary through-hole. A spring is sleeved on the outside of the guide rod.
[0007] Preferably, an auxiliary slide is fixedly connected to the bottom of the guide sleeve, and a second guide wheel is rotatably connected in the outward-facing open groove structure of the auxiliary slide. The interior of the auxiliary slide and the interior of the guide sleeve are sleeved together.
[0008] Preferably, a clamp is fixedly connected to the right side of the guide sleeve, a limiting square tube passes through the middle of the clamp, and a grooved connector is detachably connected to the bottom of the limiting square tube by bolts. The grooved connector is sleeved on the outside of the limiting square tube.
[0009] Preferably, the upper end of the defined square tube is sleeved with a sleeve, and a rhomboid tube is fixedly connected to the upper right position of the sleeve. A retainer is fixedly connected to the upper right end of the rhomboid tube. Double-headed bent rods pass through both the front and rear ends of the retainer, and the horizontal bar of the double-headed bent rod has an external thread structure.
[0010] Preferably, the auxiliary through-hole has a tapered structure that is wider at the top and narrower at the bottom. The upper end of the movable inner inclined plate is fitted to the top of the auxiliary through-hole. One side of the guide rod is fixedly connected to the outer wall of the auxiliary through-hole. The two ends of the spring are fixedly connected to the chuck and the connecting rod, respectively. The connection and the connection of the two movable support rods at the front and rear form an "H" shaped structure.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In this invention, the auxiliary insertion port, fixed inner inclined plate, movable inner inclined plate, support rod, first guide wheel, movable support rod, connecting rod, guide rod, chuck, and spring are provided to facilitate the introduction of the drip irrigation tape into the guide sleeve and auxiliary slide before the cotton seedling planting drip irrigation tape film laying guide device can be used.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0018] Please see Figure 1-3 This utility model provides a technical solution:
[0019] A cotton seedling drip irrigation tape film laying guide device includes a guide sleeve 1. The top of the guide sleeve 1 is connected to an auxiliary through-hole 2. A fixed inner inclined plate 3 is fixedly connected to the right side of the inside of the auxiliary through-hole 2. A movable inner inclined plate 4 is provided on the left side of the inside of the auxiliary through-hole 2. A support rod 5 is fixedly connected to the bottom of both the movable inner inclined plate 4 and the fixed inner inclined plate 3. A first guide wheel 6 is sleeved on the outside of the middle of the support rod 5. A movable support rod 7, which is slidably connected to the auxiliary through-hole 2, is fixedly connected to the left side of the support rod 5 connected to the movable inner inclined plate 4. A connecting rod 8 is fixedly connected between the two movable support rods 7. A guide rod 9 passes through the middle of the connecting rod 8. A chuck 10 is fixedly connected to the side of the guide rod 9 away from the auxiliary through-hole 2. A spring 11 is sleeved on the outside of the guide rod 9.
[0020] like Figure 1 and Figure 2As shown, an auxiliary slide 19 is fixedly connected to the bottom of the guide sleeve 1. A second guide wheel 20 is rotatably connected to the outward-facing open groove structure of the auxiliary slide 19. The inner sleeve of the auxiliary slide 19 and the inner sleeve of the guide sleeve 1 are designed so that when the drip irrigation tape is brought out from the auxiliary slide 19, the second guide wheel 20 will use its own rotation generated by friction with the drip irrigation tape to precisely guide it. A clamp 13 is fixedly connected to the right side of the guide sleeve 1. A limiting square tube 14 passes through the middle of the clamp 13. A trenching connector 15 is detachably connected to the bottom of the limiting square tube 14 by bolts. The 15 is fitted onto the outside of the limiting square tube 14. This structure facilitates the quick transfer of the limiting square tube 14 to the ditching implement via the ditching connector 15. The upper end of the limiting square tube 14 is fitted with a sleeve 16. A diagonal square tube 17 is fixedly connected to the upper right position of the sleeve 16. A retainer 18 is fixedly connected to the upper right end of the diagonal square tube 17. Double-headed bent rods 12 pass through both the front and rear ends of the retainer 18. The horizontal bar of the double-headed bent rod 12 has an external thread structure. The reserved settings of the retainer 18 and the double-headed bent rod 12 facilitate the quick connection of the limiting square tube 14 to the crossbeam of the seeder covering mechanism.
[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the auxiliary inlet 2 has a tapered structure that is wider at the top and narrower at the bottom. The upper end of the movable inner inclined plate 4 is fitted to the top of the auxiliary inlet 2. One side of the guide rod 9 is fixedly connected to the outer wall of the auxiliary inlet 2. The two ends of the spring 11 are fixedly connected to the chuck 10 and the connecting rod 8, respectively. The connection with the front and rear movable support rods 7 forms an "H"-shaped structure. The auxiliary inlet 2 has a tapered structure that is wider at the top and narrower at the bottom, which can expand the inlet range of the guide sleeve 1 so that the drip irrigation tape can be quickly inserted.
[0022] Workflow: The device in this utility model needs to be installed on the film covering mechanism of the seeder during use. Specifically, after the guide sleeve 1 is fitted onto the outside of the limiting square tube 14 through the clamp 13, the clamp 18 is pressed against the reserved position on the crossbeam of the film covering mechanism. The double-ended bent tube is passed through the reserved hole of the crossbeam, and then the nut is installed and tightened. The limiting square tube 14, together with the guide assembly, can then be installed on the film covering mechanism of the seeder. Before cotton sowing, when the drip irrigation tape required for planting is introduced into the device, with the upper and lower guide tubes set, the first end of the drip irrigation tape is aligned with the inside of the auxiliary through-hole 2 and pulled to insert it into the inclined plate of the auxiliary through-hole 2. At this time, as the drip irrigation tape is gradually pushed down, the fixed inner inclined plate 3 and the movable inner inclined plate 4 installed inside the auxiliary through-hole 2 will pre-guide the drip irrigation tape precisely. Then, the two first guide wheels 6 on the left and right will rotate due to the friction of the drip irrigation tape and perform secondary rolling guidance on the drip irrigation tape, so that the drip irrigation tube can be accurately inserted. Inside the guide sleeve 1, the operator efficiently completes the tape insertion operation in one go. Then, the drip irrigation tape is passed through the guide sleeve 1 and the auxiliary slide 19, so that the drip irrigation tape fits into the second guide wheel 20. The entire drip irrigation tape is then connected to the guiding device. When driving the seeder to plant cotton, after fixing the first end of the drip irrigation tape to the first end of the planting row, as the seeder moves forward, the film roll installed on the film covering mechanism rotates. The drip irrigation tape will pass through the auxiliary opening 2, the guide sleeve 1, and the auxiliary slide 19 in sequence, achieving precise delivery and laying on the planting ground. At the same time, when the knotted part of the drip irrigation tape is laid and is preferentially fed into the auxiliary opening 2, the movable inner inclined plate 4, which is squeezed by the knotted part of the drip irrigation tape, will squeeze the spring 11 through the support rod 5, the movable support rod 7, and the connecting rod 8, so that the movable inner inclined plate 4 can also be accurately fed into the guide sleeve 1 for guidance.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
