Description

Technical Field

[0001] This utility model relates to the field of forestry, specifically to a fertilization device for forest trees. Background Technology

[0002] A forestry tree fertilization device is a specialized piece of machinery used in forestry operations to apply fertilizer, aiming to improve tree growth quality and promote forestry development. This device is designed and manufactured with different usage environments and needs in mind to ensure that fertilizer is effectively absorbed by the trees.

[0003] Traditional forestry tree fertilization requires manual labor, using shovels to dig around the seeds and then pouring in fertilizer. This two-step process is labor-intensive and inefficient. Therefore, a forestry tree fertilization device that can be used for both shoveling and fertilizing, and which also has a built-in drainage system, is needed to improve work efficiency. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a fertilization device for forestry trees.

[0005] This utility model is achieved through the following technical solution:

[0006] A forestry tree fertilization device includes a shovel head with a concave back. Two L-shaped blocks are symmetrically fixed to the top of the shovel head. A hollow tube is hinged between the two L-shaped blocks via a circular protrusion. The bottom end of the hollow tube can be inserted into the concave back of the shovel head. A cover is provided at the bottom end of the hollow tube. An L-shaped plate is fixedly connected to the side wall of one of the L-shaped blocks. The top of the L-shaped plate is U-shaped. A first limiting plate is provided at the top of both L-shaped blocks. The first limiting plate is fixedly sleeved on the outer wall of the hollow tube. A handle is provided at the top of the first limiting plate. The handle is sleeved on the outer wall of the hollow tube, and the bottom end of the handle is fitted against the top of the first limiting plate. A plug is fixedly connected to the side wall of the handle. The rod is capable of being inserted into and slidably connected to the U-shaped opening at the top of the L-shaped plate. The top of the handle is fixedly connected to one end of a spring, which is sleeved on the outer wall of the hollow tube. The other end of the spring is fixedly connected to a second limiting plate. A fertilizer box is provided on one side of the hollow tube. A conveying hose is provided between the hollow tube and the fertilizer box. Several rubber protrusions are evenly fixedly connected to the outer wall of the conveying hose. Both ends of the conveying hose are fixedly connected to connectors. One connector is screwed to and communicates with the hollow tube, and the other connector is screwed to and communicates with the output end of the fertilizer box. A drain ring is sleeved at the center of the conveying hose. Several rubber protrusions are evenly fixedly connected to the inner wall of the drain ring.

[0007] Preferably, the inner wall of the connector has an annular rotating groove, a limiting ring is fixedly connected to the bottom surface of the rotating groove, a rotating ring is rotatably connected to the outer wall of the limiting ring, the bottom end of the rotating ring is fitted to the bottom surface of the rotating groove, a winding roller is fixedly connected to the top end of the rotating ring, a pull rope is wound on the winding roller, the pull rope passes through the connector and is slidably connected to it, one end of the pull rope in the two connectors passes through the corresponding connector and is fixedly connected to the two side walls of the unblocking ring, an inclined rod is fixedly connected to the inner wall of the winding roller, a torsion spring is sleeved on the outer wall of the rotating ring, the top end of the torsion spring is fixedly connected to the bottom end of the winding roller, and the bottom end of the torsion spring is fixedly connected to the bottom surface of the rotating groove.

[0008] Compared with existing technologies, the beneficial effects of this utility model are as follows: After digging, pressure is applied to the top of the hollow tube, causing the bottom of the hollow tube to move away from the recess on the back of the shovel head, allowing fertilizer to flow through the hollow tube into the dug pit, thus fertilizing the trees. After prolonged operation, the unblocking ring slides back and forth, causing the rubber protrusions on the inner wall of the unblocking ring to collide with the rubber protrusions on the outer wall of the conveying hose, causing the conveying hose to vibrate and ensuring smooth flow of fertilizer within the conveying hose, preventing blockage. When the unblocking ring is slid closer to the fertilizer box, it drives the corresponding winding roller to rotate, and the inclined rod can act as a stirrer, making it difficult for fertilizer to accumulate. After the unblocking ring is released, under the action of the torsion spring, it drives the winding roller to rotate in the opposite direction, causing the unraveled pull rope to rewind onto the winding roller. This allows the unblocking ring to slide repeatedly while the inclined rod can repeatedly stir, thus unblocking the connector. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0016] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a forestry tree fertilization device includes a shovel head 1 with a concave back. L-shaped blocks 2 are symmetrically fixed to the top of the shovel head 1. A hollow tube 3 is hinged between the two L-shaped blocks 2 via a circular protrusion. The bottom end of the hollow tube 3 can be inserted into the concave back of the shovel head 1. A cover is provided at the bottom end of the hollow tube 3. An L-shaped plate 4 is fixedly connected to the side wall of one of the L-shaped blocks 2. The top of the L-shaped plate 4 is U-shaped. A first limiting plate 5 is provided at the top of the two L-shaped blocks 2. The first limiting plate 5 is fixedly sleeved on the outer wall of the hollow tube 3. A handle 6 is provided at the top of the first limiting plate 5. The handle 6 is sleeved on the outer wall of the hollow tube 3, and the bottom end of the handle 6 is fitted against the top of the first limiting plate 5. The side wall of the handle 6 is fixedly... A fixed connection is provided with a plug rod 7, which can be inserted into the U-shaped opening at the top of the L-shaped plate 4 and slidably connected thereto. The top of the handle 6 is fixedly connected to one end of a spring 8, which is sleeved on the outer wall of the hollow tube 3. The other end of the spring 8 is fixedly connected to a second limiting plate 9. A fertilizer box 10 is provided on one side of the hollow tube 3. A conveying hose 11 is provided between the hollow tube 3 and the fertilizer box 10. Several rubber protrusions 12 are evenly fixedly connected to the outer wall of the conveying hose 11. Both ends of the conveying hose 11 are fixedly connected to connectors 13. One connector 13 is screwed to and communicates with the hollow tube 3, and the other connector 13 is screwed to and communicates with the output end of the fertilizer box 10. A drain ring 14 is sleeved at the center of the conveying hose 11. The inner wall of ring 14 is uniformly and fixedly connected with multiple rubber protrusions 12. During use, the worker carries the fertilizer box 10 on their back, holds the hollow tube 3, and uses a shovel head 1 to dig multiple fertilization pits around the seeds requiring fertilizer. While digging, a cap is needed at the bottom of the hollow tube 3 to block the opening and prevent fertilizer from leaking out. At this time, the spring 8 remains under pressure, ensuring the bottom of the handle 6 is tightly against the top of the first limiting plate 5. The first limiting plate 5 restricts the handle 6 from sliding downwards, allowing the insertion rod 7 to insert into the U-shaped opening at the top of the L-shaped plate 4. After digging the pit, the handle 6 is slid upwards, causing the insertion rod 7 to slide upwards and disengage from the U-shaped opening at the top of the L-shaped plate 4. At this time, the spring 8 is compressed, and the second limiting plate 9 restricts the spring 8 from sliding upwards. Then, the top of the hollow tube 3... Applying pressure to the end causes the bottom end of the hollow tube 3 to rotate around the circular protrusion between the L-shaped blocks 2, moving the bottom end of the hollow tube 3 away from the recessed area on the back of the shovel head 1. Then, the cover at the bottom end of the hollow tube 3 is opened, allowing fertilizer to enter the conveying hose 11 through the connector 13 screwed to the output end of the fertilizer box 10. The fertilizer then flows into the hollow tube 3 through the connector 13 screwed to the top end of the hollow tube 3, and then flows into the dug pit through the opening of the hollow tube 3, thus fertilizing the trees. To prevent blockage of the conveying hose 11 during fertilization, several rubber protrusions 12 are evenly arranged on the outer wall of the conveying hose 11, with a clearing ring 14 sleeved in the middle. The inner wall of the clearing ring 14 is also evenly arranged with multiple rubber protrusions 12. After prolonged operation, the clearing ring 14 slides back and forth.The rubber protrusions 12 on the inner wall of the unblocking ring 14 collide with the rubber protrusions 12 on the outer wall of the conveying hose 11, causing the conveying hose 11 to vibrate. This ensures smooth flow of fertilizer within the conveying hose 11 and prevents blockages.

[0017] The inner wall of the connector 13 has an annular rotating groove 16. A limiting ring 17 is fixedly connected to the bottom surface of the rotating groove 16. A rotating ring 18 is rotatably connected to the outer wall of the limiting ring 17. The bottom end of the rotating ring 18 is fitted against the bottom surface of the rotating groove 16. A winding roller 19 is fixedly connected to the top end of the rotating ring 18. A pull rope 15 is wound on the winding roller 19. The pull rope 15 passes through the connector 13 and is slidably connected to it. One end of the pull rope 15 in each of the two connectors 13 passes through the corresponding connector and is fixedly connected to the two side walls of the unblocking ring 14. A diagonal rod 20 is fixedly connected to the inner wall of the winding roller 19. A torsion spring 21 is sleeved on the outer wall of the rotating ring 18. The top end of the torsion spring 21 is fixedly connected to the bottom end of the winding roller 19, and the bottom end of the torsion spring 21 is fixedly connected to the bottom surface of the rotating groove 16. During use, while unblocking the conveying hose 11... The connector 13 also needs to be cleared. When the clearing ring 14 is slid closer to the fertilizer box 10, the pull rope 15 inside the connector 13 connected to the top of the hollow tube 3 will unravel. At this time, it will drive the corresponding winding roller 19 to rotate. The inclined rod 20 can play a stirring role, making it difficult for fertilizer to accumulate and allowing it to enter the hollow tube 3 more smoothly. The rotating ring 18 also rotates accordingly, while the limiting ring 17 remains stationary, which can play a role in preventing the rotating ring 18 and the winding roller 19 from shaking. After the clearing ring 14 is released, under the action of the torsion spring 21, it will drive the winding roller 19 to rotate in the opposite direction, so that the unraveled pull rope 15 is rewound onto the winding roller 19. This allows the clearing ring 14 to slide repeatedly while the inclined rod 20 can repeatedly stir, thus clearing the connector 13. The same principle applies when the clearing ring 14 slides closer to the hollow tube 3.
