Description
Technical Field
[0001] This utility model relates to the field of seeder technology, specifically to an anti-winding device for drip irrigation tape. Background Technology
[0002] In modern large-scale agricultural planting, sowing and irrigation are the core processes to ensure crop growth. As a high-efficiency sowing equipment, the seeder has become a key tool for large-scale farmland operations. With the increasing demands for efficiency and water resource utilization in agricultural production, the traditional operation mode of separating sowing and irrigation has gradually revealed obvious limitations and is difficult to meet the production needs of modern agriculture.
[0003] In the current process of drip irrigation tape delivery and laying, problems such as tape entanglement, jamming, and wear are common. Due to the unevenness of farmland ground and the vibration generated by the seeder during operation, drip irrigation tape is prone to entanglement with seeder components when being delivered synchronously with the equipment or laid separately. This can lead to interruptions in tape delivery, requiring manual intervention and severely impacting work efficiency. In severe cases, it can cause tearing and damage to the tape, increasing material costs. Furthermore, some simple drip irrigation tape limiting devices use fixed clamping structures, which cannot adapt to changes in the tape's position caused by ground undulations or vibrations. This not only fails to prevent entanglement but also generates significant sliding friction between the rigid clamp and the tape, accelerating tape wear and shortening its service life. Therefore, a drip irrigation tape anti-entanglement device is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an anti-tangling device for drip irrigation tape, which solves the problem of drip irrigation tape easily tangling.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a drip irrigation tape anti-winding device, including a seeder, wherein a seeding pressure roller is provided on the front surface of the seeder; The seeder is equipped with a drip irrigation mechanism, which includes a water storage tank, a water delivery pipe, a drip irrigation head, a connecting rod, and a hollow cylinder. The water storage tank is fixedly installed on the upper surface of the seeder, and the water delivery pipe is fixedly installed on the right surface of the water storage tank. Multiple drip irrigation heads are fixedly installed on the outer surface of the water delivery pipe.
[0006] Preferably, multiple connecting rods are fixedly installed on the front surface of the seeder, the connecting rods are cylindrical, and multiple hollow cylinders are fixedly installed at the front ends of the multiple connecting rods respectively.
[0007] Preferably, the drip irrigation mechanism further includes a chute, a sliding hole, and a first spring. Two chutes are formed on the outer surface of the hollow cylinder, and four sliding holes are formed in the inner walls of the two chutes respectively. The four first springs are fixedly installed in the inner walls of the two slides.
[0008] Preferably, the drip irrigation mechanism further includes a fixing plate and a collar, with the four fixing plates respectively fixedly installed on the opposite ends of the four first springs, and the opposite surfaces of the four fixing plates are all inclined. Two collars are fixedly installed on the outer surface of the four collars, and the two collars are slidably connected to the two sliding grooves respectively.
[0009] Preferably, the drip irrigation mechanism further includes four second springs and fixing blocks. The four second springs are respectively fixedly installed in the inner walls of the two slides, and the four fixing blocks are respectively fixedly installed on the opposite ends of the four second springs. The opposite surfaces of the four fixing blocks are all inclined.
[0010] Preferably, the drip irrigation mechanism further includes sliding rollers and clamping plates, with four sliding rollers fixedly installed on the opposite sides of four fixed blocks, and four clamping plates fixedly installed on the opposite ends of the four sliding rollers.
[0011] Preferably, the connecting rod is configured as a tripod.
[0012] Compared with the prior art, this utility model provides an anti-tangling device for drip irrigation tape, which has the following beneficial effects: This drip irrigation tape anti-tangling device uses a first spring, a second spring, a fixed plate, a sliding roller, and a clamping plate to form a dual elastic adjustment mechanism. When the drip irrigation tape shifts due to ground undulations or machine vibration, the second spring compresses and relaxes, causing the fixed block, sliding roller, and clamping plate to dynamically adjust the clamping width, preventing the drip irrigation tape from shifting. If the shift is large, the first spring will drive the collar to slide along the groove, further fine-tuning the position of the fixed plate and clamping plate. This design can adapt to changes in the position of the drip irrigation tape in real time, stably confining it within the preset delivery path, effectively solving the problems of easy tangling and jamming of drip irrigation tape in traditional devices. At the same time, the sliding roller converts sliding friction into rolling friction, reducing wear on the drip irrigation tape and ensuring a smooth and continuous delivery process.
[0013] This drip irrigation tape anti-tangling device uses a seeder as its basic carrier, integrating a drip irrigation mechanism consisting of a water tank, water delivery pipe, and drip irrigation head with a seeding roller, connecting rod, and hollow cylinder. When the seeder is moving, the seeding roller can simultaneously complete the soil compaction operation. Water in the water tank is transported to the drip irrigation head through the water delivery pipe, directly and precisely dripping irrigation onto the sowing area without the need for separate drip irrigation operations. This reduces the process intervals in agricultural production and lowers labor and time costs. At the same time, the connecting rod is set up like a tripod, providing stable support for the hollow cylinder and ensuring that the anti-tangling module works in coordination with the sowing and drip irrigation modules. This prevents the overall operation rhythm from being affected by loose parts, improving the comprehensive efficiency of sowing and irrigation, and is especially suitable for large-scale farmland operations.

[0016] 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.
[0017] Please see Figure 1-4 This utility model provides a new technical solution: a drip irrigation tape anti-winding device, including: a seeder 1: as the basic carrier of the entire drip irrigation tape anti-winding device, all components such as water storage tank 2, seeding roller 5, connecting rod 6 are directly or indirectly installed on its surface. It not only provides support for the seeding operation, but also integrates the seeding and drip irrigation functions, ensuring that the drip irrigation operation can be carried out simultaneously during the seeding process. It is the core support framework for the device to achieve collaborative operation. Water storage tank 2: Fixedly installed on the upper surface of seeder 1, its main function is to store the water required for drip irrigation. It provides a stable water supply guarantee for the entire drip irrigation system. Through the connection with water delivery pipe 3, the water stored inside is transported to the subsequent drip irrigation components in an orderly manner, avoiding the impact of unstable water supply on the drip irrigation effect. It is the "water source reserve" of the drip irrigation mechanism. Water delivery pipe 3: Fixedly installed on the right surface of water storage tank 2, it is the key water delivery channel connecting water storage tank 2 and drip irrigation head 4. It can efficiently and evenly deliver water in water storage tank 2 to multiple drip irrigation heads 4, while ensuring the sealing during the water delivery process to prevent water leakage and ensure that the water flow reaches the drip irrigation execution end stably, thus providing a guarantee for the water supply to drip irrigation head 4. Drip head 4: Multiple drip heads 4 are fixedly installed on the outer surface of the water delivery pipe 3. They are the final execution components of the drip irrigation operation. Their core function is to slowly and precisely drip the water delivered by the water delivery pipe 3 into the soil, directly providing water for seed growth. Through the reasonable distribution of multiple drip heads 4, uniform irrigation of the sowing area can be achieved, improving water resource utilization. Seeding roller 5: Located on the front surface of seeder 1, it mainly plays a role after the sowing operation. After the seeder 1 finishes sowing, the sowing roller 5 will move with the device to compact the soil, cover the seeds under the soil and compact the soil. This can prevent the seeds from being exposed to the outside environment and enhance the soil's water retention, creating suitable soil conditions for seed germination. Connecting rod 6: Multiple connecting rods 6 are fixedly installed on the front surface of the seeder 1 and are set up in the form of a tripod, which has strong support stability. Its main function is to connect the seeder 1 and the hollow cylinder 7, provide a stable installation support point for the hollow cylinder 7, so that the hollow cylinder 7 can be stably placed in the designated position, and ensure the normal operation of the subsequent anti-winding components. It is an important support structure of the anti-winding module. Hollow cylinder 7: Multiple hollow cylinders 7 are fixedly installed at the front end of multiple connecting rods 6, which is the installation basis of the anti-winding adjustment module. The sliding groove 8 opened on its outer surface provides sliding space for the collar 11. The sliding hole 16 in the inner wall and the first spring 9, second spring 12 and other components together constitute the structural basis of the anti-winding adjustment, which can cooperate with other components to realize the limiting and anti-winding adjustment of the drip irrigation tape. Slide 8: It is formed on the outer surface of the hollow cylinder 7. Its main function is to provide a sliding track for the collar 11, so that the collar 11 can slide flexibly along the slide 8, thereby driving the fixed plate 10 to adjust its position. At the same time, the slide 8 also provides space for the installation of the first spring 9 and the second spring 12, ensuring that these elastic components can play a stable role. It is a key guiding structure for the movement of components during the anti-winding adjustment process. First spring 9: Four first springs 9 are fixedly installed in the inner walls of the two sliding grooves 8 and connected to the fixing plate 10. They have elastic expansion and contraction characteristics. When the position of the drip irrigation tape changes and exerts a force on the fixing plate 10, the first spring 9 can buffer and adjust by expansion and contraction, so as to drive the fixing plate 10 to adapt to the position change of the drip irrigation tape and help prevent the drip irrigation tape from getting tangled. Fixing plate 10: Four fixing plates 10 are respectively fixedly installed on the opposite ends of the four first springs 9, and the opposite surfaces are set at an angle. The angled design makes it easier to fit the drip irrigation tape better. Under the drive of the first springs 9, the fixing plates 10 can play a certain role in limiting and guiding the drip irrigation tape, guiding the drip irrigation tape to maintain a stable delivery path and reducing the risk of entanglement caused by positional deviation. Collar 11: Two collars 11 are respectively fixedly installed on the outer surface of the four fixing plates 10 and slidably connected to the two sliding grooves 8. It is a key component connecting the fixing plates 10 and the sliding grooves 8, and can slide the fixing plates 10 along the sliding grooves 8, making the position adjustment of the fixing plates 10 smoother. At the same time, the sliding of the collars 11 can also cooperate with the extension and contraction of the first spring 9 to further optimize the limiting effect on the drip irrigation tape and help prevent tangling.
[0018] Second spring 12: Four second springs 12 are fixedly installed in the inner walls of the two sliding grooves 8 and connected to the fixing block 13. Similar to the first spring 9, it also relies on elastic expansion and contraction to function. When the drip irrigation tape exerts pressure on the fixing block 13, the second spring 12 can buffer the pressure by expansion and contraction, driving the fixing block 13 to adjust its position. It works in conjunction with the first spring 9 to form a double elastic adjustment, enhancing the anti-tangling effect.
[0019] Fixing block 13: Four fixing blocks 13 are respectively fixedly installed on the opposite ends of four second springs 12, and the opposite surfaces are set at an angle. The angled design facilitates contact with the drip irrigation tape. Under the action of the second springs 12, the fixing blocks 13 can fit tightly against the drip irrigation tape, which further limits and fixes the drip irrigation tape, prevents the drip irrigation tape from shaking or shifting significantly during transportation, and reduces the possibility of tangling. Sliding roller 14: Four sliding rollers 14 are fixedly installed on the opposite sides of four fixed blocks 13 respectively. They can rotate around their own axis. When the drip irrigation tape contacts and moves with the sliding roller 14, the sliding roller 14 will rotate accordingly, converting the sliding friction between the drip irrigation tape and the fixed block 13 into rolling friction, reducing the wear on the drip irrigation tape, ensuring smooth delivery of the drip irrigation tape, and assisting in preventing tangling. Clamping plates 15: Four clamping plates 15 are fixedly installed at the opposite ends of the four sliding rollers 14. Their main function is to clamp and limit the drip irrigation tape. By clamping the tape with the clamping plates 15, the drip irrigation tape can be restricted within the specified conveying range, preventing it from deviating from the preset path during movement and avoiding entanglement with other components. At the same time, the clamping plates 15 can also work with the sliding rollers 14 to ensure stable delivery of the drip irrigation tape. Sliding holes 16: Four sliding holes 16 are respectively opened in the inner walls of the two sliding grooves 8, mainly to provide space for the installation and movement of related components. They can prevent the components from getting stuck when moving in the sliding grooves 8, and ensure smoother extension and contraction of components such as the first spring 9 and the second spring 12, as well as smoother movement of the fixing plate 10 and the fixing block 13, providing structural protection for the normal operation of the anti-winding adjustment module. The drip irrigation tape anti-winding device guides the drip irrigation tape through the clamping channel formed by the clamping plate 15 inside the hollow cylinder 7. The elastic force generated by the initial deformation of the second spring 12 causes the clamping plate 15 to clamp the drip irrigation tape. The collar 11 is in the initial position of the sliding groove 8 under the action of the first spring 9. The water storage tank 2 is filled with irrigation water. The seeder 1 moves forward, and the sowing pressure roller 5 on its front surface moves and rolls with the machine to compact the soil after sowing. At the same time, the water in the water storage tank 2 flows into the water delivery pipe 3 and continuously drips into the soil through the drip irrigation head 4. As the seeder 1 moves forward, the drip irrigation tape is conveyed forward synchronously with the device. The sliding roller 14 rolls under the drive of the drip irrigation tape to reduce the conveying resistance. If the drip irrigation tape shifts due to ground undulations or machine vibration, causing the clamping plate 15 on one side to shift, the device will be unable to deliver the tape. When the force increases, the second spring 12 on this side is compressed, which drives the fixed block 13 to move towards the inner wall of the slide 8. At the same time, the second spring 12 on the other side relaxes, pushing the corresponding fixed block 13 to move outward, realizing the dynamic adjustment of the clamping width of the clamping plate 15. If the offset is large, the first spring 9 will slide with the collar 11 in the slide 8, further driving the fixed plate 10 and the clamping plate 15 to make overall fine adjustments, ensuring that the drip irrigation tape is always in a stable conveying path and avoiding entanglement. After the seeder 1 stops moving, the seeding roller 5 stops rolling, the drip irrigation tape conveying stops synchronously, the first spring 9 and the second spring 12 return to their initial deformation, the collar 11 and the clamping plate 15 return to their initial positions, the water storage tank 2 stops supplying water to the water pipe 3, and the drip irrigation operation ends. like Figure 3 The connecting rod 6 is cylindrical in shape, with a diameter of 12mm and a length of 30cm. The surface is treated with anti-rust. One end is fixed to the mounting base on the front surface of the seeder 1 by welding, and the other end is connected to the external thread at the rear end of the hollow cylinder 7 through the internal thread to achieve horizontal fixation of the hollow cylinder 7. Each seeder 1 has 3 cylindrical connecting rods 6 evenly distributed in the transverse direction, with an adjacent spacing of 1.2m, to ensure that the supporting force on the hollow cylinder 7 is evenly distributed. In flat farmland, the seeder 1 experiences minimal vibration during operation with minimal ground undulation. The cylindrical connecting rod 6, with its simple structure and stable axial support, firmly secures the hollow cylinder 7. When the drip irrigation tape is conveyed through the clamping plate 15 inside the hollow cylinder 7, the cylindrical connecting rod 6 keeps the hollow cylinder 7 horizontal, preventing tilting due to unstable support. This prevents misalignment and friction between the drip irrigation tape and the clamping plate 15 and sliding roller 14. Furthermore, the cylindrical structure is cost-effective and easy to install. The three evenly distributed connecting rods 6 balance the forces on the hollow cylinder 7. Even if the drip irrigation tape experiences lateral tension due to slight vibration, the shear resistance of the cylindrical rods can offset this, ensuring precise alignment between the anti-winding module and the drip irrigation head 4's irrigation area. For example, in wheat sowing operations on the North China Plain, using the cylindrical connecting rod 6, the drip irrigation tape winding rate was less than 0.5% within 8 hours of continuous operation, with no significant displacement of the hollow cylinder 7, and the irrigation deviation of the drip irrigation head 4 was controlled within ±3cm.
[0020] Example 1: Tripod-shaped connecting rod 6 (application in hilly farmland) like Figure 4 When the work environment changes to hilly, undulating farmland, the cylindrical connecting rod 6 is replaced with a tripod-shaped connecting rod 6. This connecting rod 6 consists of three alloy rods with a diameter of 8mm, arranged in an equilateral triangle. The top is welded together to form a single connecting end, which is fixed to the mounting base of the seeder 1. The three bottom ends are fixed to three pre-set connecting lugs on the outer surface of the hollow cylinder 7 with bolts, forming a stable triangular structure. The overall height of the tripod can be adjusted within the range of 25-35cm by adjusting the telescopic screw at the top connecting end to adapt to farmland with different undulations. Hilly farmland has a large undulation in the ground, and the seeder 1 is prone to longitudinal and lateral vibrations when it travels. The triangular structure of the tripod-shaped connecting rod 6 has a strong anti-tipping ability and can effectively counteract the instability caused by vibration. When the seeder 1 travels on a slope of 5°-10°, the tripod-shaped connecting rod 6 can keep the hollow cylinder 7 parallel to the ground through the distributed support at the three ends of the bottom. This prevents the hollow cylinder 7 from being higher at one end and lower at the other due to the tilt of the seeder 1, and thus prevents the drip irrigation tape from sliding, piling up and tangling in lower places during transportation. In addition, the height-adjustable design can adapt to different undulating ground, such as in hilly areas. In corn planting operations in the area, when a certain area of the ground is 10cm higher than the adjacent area, the hollow cylinder 7 can be kept horizontal by shortening the telescopic screw of the connecting rod 6 in that area. This ensures that the drip irrigation tape is always delivered along the clamping channel of the clamping plate 15. At the same time, the support area of the tripod-shaped structure is 3 times larger than that of the cylindrical structure, which can further distribute the weight of the hollow cylinder 7 and the drip irrigation tape, reduce the stress on the mounting base of the seeder 1, and extend the overall service life of the device. In practical applications, when the device using the tripod-shaped connecting rod 6 is used in hilly farmland, the drip irrigation tape entanglement rate is controlled within 1%, which is far lower than the 3%-5% of the traditional fixed structure.
