Description

Technical Field

[0001] This utility model relates to the field of forest tree cultivation technology, specifically a soil loosening device for Pinus sylvestris seedling cultivation. Background Technology

[0002] Forest cultivation refers to the process of promoting tree growth and development, improving tree growth rate and quality, and maximizing the economic benefits of forestry through reasonable fertilization, pruning, and watering. Forest cultivation has significant economic and ecological importance in forestry production.

[0003] Before cultivating Pinus sylvestris seedlings, the soil needs to be loosened. Loosening the soil increases its permeability, which is beneficial for root respiration and growth. In existing technologies, most soil loosening devices break up and loosen the soil by rotating rotary tillers. However, during the loosening process, stones on the ground cannot be cleared. The rotary tillers collide with the stones when rotating, which can easily damage the tillers and reduce the effectiveness of the loosening device. Therefore, it is necessary to redesign a soil loosening device for Pinus sylvestris seedling cultivation to address the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a soil loosening device for Pinus sylvestris seedlings, which solves the problem that traditional soil loosening devices cannot clear stones from the ground, and that the rotary tiller blades collide with stones when rotating, easily causing damage to the rotary tiller blades.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a soil loosening device for Pinus sylvestris seedling cultivation, which has the following beneficial effects:

[0015] 1. By setting up components such as sliding rods, mounting frames and guide wheels, multiple guide wheels can extend outward under the support of the sliding rods. As the base plate moves through multiple pulleys, multiple guide wheels can contact the stones on the ground. With the cooperation of multiple rotating guide wheels, the stones can be guided to both sides of the base plate, thereby avoiding damage to the rotary tiller blades by the stones.

[0016] 2. By setting components such as a screw, a limiting rod, and a moving block, the screw can drive the moving block to move when it rotates through cooperation with the limiting rod. The moving block then drives the connecting frame to move downward through cooperation with the connecting rod. Driven by the screw, the vertical height of the connecting frame can be easily adjusted, thereby facilitating the adjustment of the rotary tillage depth. Attached Figure Description

[0025] This utility model provides a technical solution:

[0026] Please see Figures 1-5 A soil-loosening device for Pinus sylvestris seedling cultivation includes a base plate 1. Multiple pulleys 2 are fixedly installed on the bottom wall of the base plate 1. A connecting frame 3 is fixedly installed on the upper surface of the base plate 1. A screw 5 is rotatably installed on the upper surface of the connecting frame 3 via a lifting frame 4. A first motor 6 connected to the screw 5 is fixedly installed on the upper surface of the lifting frame 4. A moving block 8 is threadedly installed on the outer wall of the screw 5 via a limiting mechanism. A connecting frame 10 is fixedly connected to the outer wall of the moving block 8 via a connecting mechanism. A movable opening that mates with the connecting frame 10 is opened on the upper surface of the base plate 1. A rotating shaft 11 is rotatably installed inside the connecting frame 10. A second motor 12 connected to a rotating shaft 11 is fixedly installed on the outer wall of the connecting frame 10. Multiple mounting sleeves 13 are fixedly installed on the outer wall of the rotating shaft 11. Multiple rotary tillage blades 14 are fixedly installed on the outer wall of each mounting sleeve 13. Multiple sliding rods 16 are slidably installed on the bottom wall of the base plate 1 through a connecting plate 15. A mounting frame 17 is fixedly installed at the end of each sliding rod 16. A guide wheel 18 is rotatably installed inside each mounting frame 17. A limit plate 19 is fixedly installed on the outer wall of each sliding rod 16. The outer wall of each limit plate 19 is connected to the inner wall of the connecting plate 15 through an elastic mechanism.

[0027] Furthermore, the limiting mechanism includes a limiting rod 7 fixedly installed inside the lifting frame 4, and the limiting rod 7 slides through the moving block 8.

[0028] Furthermore, the connecting mechanism includes a connecting rod 9 fixedly installed on the outer wall of the movable block 8, and the end of the connecting rod 9 is fixedly connected to the upper end face of the connecting frame 10.

[0029] Furthermore, the elastic mechanism includes a spring 20 installed on the outer wall of the slide bar 16, with both ends of the spring 20 elastically connected to the inner wall of the connecting plate 15 and the outer wall of the limiting plate 19, respectively.

[0030] Furthermore, a storage battery 21 is slidably installed inside the connecting frame 3, and the storage battery 21 is electrically connected to the first motor 6 and the second motor 12.

[0031] Furthermore, two connecting rods 22 are fixedly installed on the upper surface of the base plate 1, and handrails 23 are fixedly connected to the ends of the two connecting rods 22.

[0032] In practical use, the working principle of this utility model is as follows:

[0033] The base plate 1 can be pushed by the cooperation of the handle 23 and the connecting rod 22. At this time, the base plate 1 can be moved conveniently by multiple pulleys 2. Before loosening the soil, the battery 21 can provide convenient power to the first motor 6 and the second motor 12. During the movement of the base plate 1 by multiple pulleys 2, multiple guide wheels 18 can contact the stones on the ground. With the cooperation of the multiple guide wheels 18 installed in rotation, the stones can be guided to both sides of the base plate 1, thereby avoiding damage to the rotary tillage blades 14 by the stones. When the guide wheels 18 contact the stones, the mounting frame 17 is subjected to force, which can drive the sliding rod 16 to slide and cause the limiting plate 19 to pull the spring 20. This allows for elastic adjustment of the extension position of the guide wheels 18, avoiding damage to the guide wheels 18 due to hard contact with the stones.

[0034] When loosening the soil on the ground, the first motor 6 can drive the screw 5 to rotate. When the screw 5 rotates, it can drive the moving block 8 to move through the cooperation of the limiting rod 7. The moving block 8 then drives the connecting frame 10 to move downward through the cooperation of the connecting rod 9. At this time, the connecting frame 10 can move to the bottom of the base plate 1 through the moving opening. Then, the second motor 12 can drive the rotating shaft 11 to rotate. The rotating shaft 11 then drives multiple rotary tillage blades 14 to rotate through the mounting sleeve 13 to break and loosen the soil on the ground. Under the drive of the screw 5, the vertical height of the connecting frame 10 can be easily adjusted, thereby facilitating the adjustment of the rotary tillage depth.

Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
