Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco planting tools, and in particular to a water pipe puller for tobacco plant protection. Background Technology
[0002] In tobacco cultivation, wet seedling raising technology is commonly used in seedling greenhouses, requiring daily water spraying. Traditionally, dragging the water hoses directly along the ground easily scratches and crushes the seedlings, causing damage. Furthermore, once the plant enters the field growing season, the pesticide delivery hoses of pump-type plant protection machines also suffer from entanglement and bending of tobacco plants when stretched in the field, affecting not only operational efficiency but also crop growth.
[0003] In existing technologies, such as the concrete curing water pipe puller disclosed in patent CN218057888U, the direction of water pipe dragging is adjusted through a main insertion rod fixation and a sleeve turntable guiding structure. However, its insertion rod adopts a single-point vertical insertion method, which is prone to swaying and tilting in soft soil, resulting in insufficient fixing stability. In addition, this device can only provide local turning support for the water pipe at the bend, and cannot form continuous guidance in long-distance straight pipe dragging scenarios, resulting in the middle section of the water pipe still contacting and rubbing against the ground, which has the problem of structural adaptability limitations. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a water pipe puller for tobacco plant protection. It adopts a rotating guide and multi-directional anchoring cooperative structure, which effectively reduces the dragging friction of the water pipe and prevents damage to tobacco plants. At the same time, it improves the stability of the device in soft soil and has both straight guidance and bending adjustment functions, so as to meet the needs of plant protection operations in seedling greenhouses and complex terrain in open fields.

[0027] like Figures 1 to 3 As shown, a water pipe puller for tobacco plant protection includes a main rod 1, a pin 6, a crossbar 2, a first rotating cylinder 4, and a pulley 5. The upper end of the main rod 1 is vertically connected to the crossbar 2. The first rotating cylinder 4 is sleeved on the outer wall of the main rod 1. The pulley 5 is provided below the first rotating cylinder 4 and is rotatably connected to the outer wall of the main rod 1. The pin 6 is provided below the pulley 5 and is slidably connected to the outer wall of the main rod 1. The water pipe 19 is in slidable contact with the first rotating cylinder 4 and the pulley 5.
[0028] During operation, the main insertion rod 1 applies downward pressure through the crossbar 2 and is inserted into the working location. The insertion pin 6 further enhances the stability of the insertion rod. When the water pipe 19 needs to change direction, it slides into contact with the first rotating drum 4, causing the first rotating drum 4 to rotate, thereby changing the direction of travel of the water pipe 19 and preventing the water pipe 19 from touching the ground. When the water pipe 19 needs to be dragged in a straight line over a long distance, multiple insertion rods can be inserted along the dragging path of the water pipe 19, and the water pipe 19 can be placed on the pulley 5 to slide, reducing the friction between the water pipe 19 and the ground and providing an auxiliary dragging effect.
[0029] Preferred solutions include Figure 2 and Figure 3 As shown, a tapered head 10 is provided at the lower end of the main insertion rod 1.
[0030] Preferred solutions include Figure 2 and Figure 3 As shown, handles 3 are provided at both ends of the crossbar 2. The handles 3 are made of flexible and non-slip material to facilitate the operation of the crossbar 2 by the staff.
[0031] Preferred solutions include Figure 2 and Figure 3 As shown, the outer wall of the main insert rod 1 is fixedly connected to the first baffle 9. The first rotating cylinder 4 is sleeved between the first baffle 9 and rotates freely around the axis of the main insert rod 1. The upper and lower end faces of the first rotating cylinder 4 are vertically connected to the turntable 7. A stop bar 8 is provided below the first rotating cylinder 4, and the end of the stop bar 8 is vertically connected to the main insert rod 1.
[0032] With the above structure, when the water pipe 19 changes its direction of travel, it abuts against the first rotating drum 4. The rotation of the first rotating drum 4 can effectively reduce friction, while the upper and lower rotating discs 7 play a supporting role, and the stop bar 8 can prevent the water pipe 19 from slipping out during the dragging process.
[0033] Preferred solutions include Figure 4 As shown, a sliding groove 11 is provided on the outer wall of the main insertion rod 1. The sliding groove 11 is arranged symmetrically in a ring around the axis of the main insertion rod 1. A lifting plate 13 is sleeved on the outer wall of the main insertion rod 1. The inner wall of the lifting plate 13 is engaged in the sliding groove 11 and slides along the sliding groove 11. An L-shaped insertion pin 6 is vertically connected to the outer wall of the lifting plate 13. The outer wall of the lifting plate 13 is vertically connected to the pressure rod 14. A magnetic block 12 is provided at the end of the sliding groove 11. The magnetic block 12 is magnetically connected to the lifting plate 13.
[0034] During use, the device is first pulled upwards by the pressure rod 14, causing the lifting plate 13 to slide upwards along the slide groove 11, so that the lifting plate 13 is attracted to the magnetic block 12. Then, the main insertion rod 1 is rotated downwards to allow it to be smoothly inserted into the working location. Finally, the pressure rod 14 is pressed downwards, causing the lifting plate 13 and the insertion pin 6 to slide downwards, ultimately allowing the insertion pin 6 to be inserted into the working location around the main insertion rod 1, which effectively improves the stability of the main insertion rod 1.
[0035] Preferred solutions include Figure 1 and Figure 5 As shown, the outer wall of the main insert rod 1 is fixedly connected to the second baffle 15. The second rotating cylinder 16 is sleeved between the second baffle 15 and rotates freely around the axis of the main insert rod 1. The cylinder wall of the second rotating cylinder 16 is perpendicularly connected to the rotating rod. A pulley 5 is sleeved on the rotating rod and rotates freely along the axis of the rotating rod. When the water pipe 19 needs to be transported in a straight line over a long distance, it can be placed on the pulley 5 and the pulley 5 can be driven to rotate, thereby effectively reducing friction and preventing the water pipe 19 from contacting the ground, thus playing an auxiliary dragging effect.
[0036] Preferred solutions include Figure 5As shown, limit holes 17 are opened on the upper part of the main insertion rod 1 and the second rotating drum 16 respectively. After the limit pin 18 is inserted into the limit hole 17, the position of the second rotating drum 16 is locked and fixed, and the stability of the device during operation is improved.
