Description

Technical Field

[0001] This utility model relates to the field of forestry planting technology, and in particular to a soil loosening device for forestry planting. Background Technology

[0002] Forestry planting refers to the production activities of artificially cultivating and planting trees and related plants in suitable afforestation areas. It encompasses seedling propagation, afforestation planning, tree species selection, and planting and management, aiming to cultivate forest resources and improve the ecological environment, while providing timber and economic forest products. It combines ecological protection, economic development, and social benefits, and is the basic core link of forestry production. In order to facilitate soil loosening before planting, a soil loosening device for forestry planting is needed.

[0003] Soil loosening devices for forestry planting refer to mechanical equipment or tools specifically designed for improving forest soil. They are used to break up soil compaction and loosen the surface or deep soil. Through the rotation or turning of blades, teeth, and plow head components, they improve soil aeration and water retention, which is beneficial to the growth of tree roots. They can also be adapted to different forest environments and planting needs.

[0004] Currently available forestry loosening devices consist of a vehicle and loosening forks. During use, the vehicle moves to move the loosening forks, facilitating loosening as the plant moves. To improve efficiency, existing technologies connect the loosening forks to a telescopic rod, using the rod's extension and retraction to increase loosening efficiency. To enhance synchronization, existing technologies employ a synchronization structure connected to the wheels, moving the loosening forks up and down simultaneously with the wheels' rotation. This improves the synchronicity between device movement and loosening. However, this method results in the loosening process being synchronized with wheel rotation. When the device encounters potholes or slopes that prevent movement or necessitate slowing down, the loosening work is forced to stop or decrease. Furthermore, the device lacks sufficient adjustment capability for loosening force when dealing with soils of varying hardness, affecting its adaptability to different plots and thus reducing its reliability.

[0033] 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.

[0034] Reference Figure 1 , Figure 4 and Figure 5An embodiment of this utility model is provided: a soil loosening device for forestry planting, including a vehicle body 1, with wheels 4 rotatably connected to the rear side of the interior of the vehicle body 1. Rotating the wheels 4 can push the vehicle body 1 to move. A hollow cover 5 is connected to the top of the vehicle body 1. A speed regulating mechanism 2 is provided in the middle of the inner side of the vehicle body 1. The speed regulating mechanism 2 is used to adjust the soil loosening efficiency according to the needs. A power mechanism 3 is provided on the upper side of the interior of the vehicle body 1. The power mechanism 3 is used to switch the power source of the device.

[0035] The speed regulating mechanism 2 includes a rotating wheel 21 and a belt 22. The two rotating wheels 21 are fixedly connected to the front and rear sides of the inner top of the vehicle body 1, respectively. The two rotating wheels 21 are connected by the belt 22 for transmission. The belt 22 can drive the two rotating wheels 21 to rotate synchronously. A reciprocating rod 210 is fixedly connected to the bottom of the front rotating wheel 21. A U-shaped frame 211 is threadedly connected to the outer side of the reciprocating rod 210. The rotation of the front rotating wheel 21 will drive the reciprocating rod 210 to rotate and push the U-shaped frame 211 to move up and down. The outer side of the U-shaped frame 211 is slidably connected to the vehicle body 1. A tackling fork 212 is set at the bottom of the U-shaped frame 211. The movement of the U-shaped frame 211 will synchronously drive the tackling fork 212 to move synchronously. A threaded rod 23 is rotatably connected to the top of the inner side of the hollow cover 5. A guide rod 215 is fixedly connected to the bottom of the inner side of the hollow cover 5. A threaded rod 215 is threadedly connected to the rear side of the outer side of the threaded rod 23. The movable block 24 can be moved by rotating the threaded rod 23. The guide rod 215 is slidably connected to the movable block 24, and the guide rod 215 can improve the movement stability of the movable block 24. The bottom of the movable block 24 is fixedly connected to the rack 25. The left and right sides of the interior of the hollow cover 5 are rotatably connected to the circular gear 214. The circular gear 214 is meshed with the rack 25. The movement of the movable block 24 will drive the rack 25 to move and thus drive the circular gear 214 to rotate. The bottom left and right sides of the circular gear 214 are fixedly connected to the limit rod 213. Rotating the circular gear 214 will drive the limit rod 213 to rotate to tighten the belt 22. The threaded rod 23 is provided with a tightening component 26. The hollow cover 5 is provided with a detection component 27. The rear side of the vehicle body 1 is provided with an auxiliary component 28. The ripping fork 212 is provided with a disassembly and assembly component 29.

[0036] Specifically, wheel 4 can drive vehicle body 1 to move, and at the same time, through belt 22, it can synchronously drive rotating wheel 21 to rotate. When the front rotating wheel 21 rotates, it will drive reciprocating rod 210 to rotate, which in turn drives U-shaped frame 211 and tumbler fork 212 to move up and down, realizing the loosening of soil. At this time, if it is necessary to adjust the degree of loosening according to the soil type, the moving block 24 can be moved back and forth by rotating threaded rod 23. The movement of moving block 24 will push rack 25, causing the circular gears on both sides to rotate, which in turn drives limit rod 213 to rotate to tighten belt 22. By controlling the speed, the reciprocating amplitude of tumbler fork 212 can be adjusted, thereby realizing the adjustment of the degree of loosening.

[0037] Reference Figure 3 , Figure 4 and Figure 6 The power mechanism 3 includes a telescopic tube 31, which is fixedly connected to the bottom of the rear rotating wheel 21. A circular gear 32 is fixedly connected to the bottom of the telescopic tube 31. When the telescopic tube 31 extends or retracts, it drives the circular gear 32 to move up and down. A bevel gear 33 is fixedly connected to the bottom of the circular gear 32. An electric telescopic rod 35 is fixedly connected to the top center of the vehicle body 1. The bottom of the electric telescopic rod 35 is slidably connected to the circular gear 32. The sliding with the circular gear 32 ensures that the extension or retraction of the electric telescopic rod 35 does not affect the rotation of the circular gear 32. Activating the electric telescopic rod 35 drives the circular gear 32 to move up and down. A bevel gear 33 is fixedly connected to the center of the outer side of the wheel 4. The rotation of the wheel 4 will synchronously drive the bevel gear 34 to rotate. The bevel gear 34 meshes with the bevel gear 33. When the bevel gear 34 rotates, the bevel gear 33 meshing with it will rotate. The top rear side of the hollow cover 5 is fixedly connected to the motor 36. The output end of the motor 36 passes through the hollow cover 5 and is fixedly connected to the circular gear 37. Starting the motor 36 will drive the circular gear 37 to rotate. The circular gear 37 meshes with the circular gear 32. Rotating the circular gear 37 will drive the circular gear 32 to rotate. The outer side of the U-shaped frame 211 is provided with a soil loosening component 38. The top rear side of the vehicle body 1 is provided with an operating component 39.

[0038] Specifically, when the rear rotating wheel 21 rotates, it synchronously drives the telescopic tube 31 to rotate, which in turn drives the circular gear 32 and the bevel gear 33 to rotate. At the same time, the rotation of the wheel 4 drives the bevel gear 34 to rotate, achieving the effect that the wheel 4 drives the vehicle body 1 to move while simultaneously driving the rotating wheel 21 to rotate. When encountering complex ground conditions or when it is difficult to move the vehicle body 1 manually and simultaneously loosen the soil, the electric telescopic rod 35 can be activated. In conjunction with the telescopic function of the telescopic tube 31, the circular gear 32 is moved so that it meshes with the circular gear 37. Then, the motor 36 is activated to drive the circular gear 37 to rotate. The power provided by the motor 36 directly drives the rotating wheel 21 to rotate, without relying on the power of the wheel 4. The motor 36 can be a YL90-750W vertical motor, and the electric telescopic rod 35 can be a YS-H1S-12-20-7-1500 model.

[0039] Reference Figure 1 , Figure 4 and Figure 5The tightening component 26 includes a second movable block 261, which is threadedly connected to the outer front side of the first threaded rod 23. The second movable block 261 is slidably connected to the guide rod 215, and a rubber plate 262 is fixedly connected to the bottom of the second movable block 261. The detection component 27 includes an indicator block 272, and multiple indicator blocks 272 are respectively fixedly connected to the outer front and rear sides of the hollow cover 5. The top of the first movable block 24 penetrates the vehicle body 1 and is fixedly connected to an indicator plate 271.

[0040] Specifically, the rotation of the threaded rod 23 will simultaneously drive the moving block 261 to move, and the rubber plate 262 will move accordingly. At this time, the movement of the rubber plate 262 will tighten the belt 22, thereby improving the restriction and speed regulation effect of the belt 22. The movement of the moving block 24 will simultaneously drive the indicator plate 271 to move. At this time, by observing the position of the indicator plate 271, the rotation amplitude of the threaded rod 23 and the movement position of the moving block 24 can be determined, thereby determining the current tightening of the belt 22 and the degree of speed regulation of the device. The guide rod 215 can also improve the movement stability of the moving block 261.

[0041] Reference Figure 1 , Figure 3 and Figure 5 The auxiliary component 28 includes a positioning block 281, which is fixedly connected to the rear side of the vehicle body 1. A plow 282 is rotatably connected to the inner side of the positioning block 281. A plug-in block 283 is fixedly connected to the top of the plow 282. Multiple counterweight blocks 284 are engaged on the outer side of the plug-in block 283. The disassembly and assembly component 29 includes a slot 292. Two slots 292 are respectively opened on the top left and right sides of the ripping fork 212. The U-shaped frame 211 can be inserted into the slot 292 on the ripping fork 212. Nuts 291 are threadedly connected to the left and right sides of the front end of the ripping fork 212. The rear side of the nut 291 passes through the slot 292 and is threadedly connected to the U-shaped frame 211. Rotating the nut 291 can disassemble and assemble the ripping fork 212 and the U-shaped frame 211.

[0042] Specifically, the rotatable plow 282 on the positioning block 281 can help improve the soil loosening effect. At this time, by inserting different numbers of counterweights 284 on the insertion block 283, the pressure and soil loosening effect and degree of the plow 282 can be adjusted according to the needs. By inserting the loosening fork 212 into the slot 292 and rotating the nut 291, the loosening fork 212 and the U-shaped frame 211 can be fixed or removed, so as to replace the loosening fork 212 of different specifications and models as needed.

[0043] Reference Figure 2 , Figure 3 and Figure 6The soil loosening component 38 includes an L-shaped plate 381, which is fixedly connected to the front side of the U-shaped frame 211. When the U-shaped frame 211 moves up and down, it pushes the L-shaped plate 381 to move synchronously. Soil loosening rollers 382 are rotatably connected to the left and right sides of the bottom of the inner wall of the vehicle body 1. The soil loosening rollers 382 can rotate along the vehicle body 1. A positioning roller 383 is fixedly connected to the outer side of the soil loosening roller 382. The positioning roller 383 rotates with the rotation of the soil loosening roller 382. The L-shaped plate 381 is slidably connected to the positioning roller 383. When the L-shaped plate 381 moves up and down, it pushes the soil loosening roller 382 to rotate through the positioning roller 383. The operating component 39 includes a bracket 391. Two brackets 391 are fixedly connected to the left and right sides of the top rear end of the vehicle body 1, respectively. A handrail 392 is fixedly connected to the top of the bracket 391. By holding the handrail 392, the vehicle body 1 can be moved and operated through the bracket 391.

[0044] Specifically, when the U-shaped frame 211 moves up and down, the L-shaped plate 381 on it also moves up and down. At this time, the up and down movement of the L-shaped plate 381 will force the positioning roller 383 to move along through the groove on its inner side, thereby pushing the loosening roller 382 to rotate. This achieves the simultaneous movement of the U-shaped frame 211 and the loosening fork 212 to loosen the soil, while the loosening roller 382 is rotated to cooperate with and assist the loosening fork 212 in loosening the soil. By holding the handle 392 on the bracket 391, it is easy to push the device to move or operate.

[0045] Working principle: Before using the device, the wheel 4 first drives the vehicle body 1 to move. The belt 22 drives the rotating wheel 21 to rotate synchronously. At this time, the rotating wheel 21 at the front will drive the reciprocating rod 210 to rotate synchronously, thereby driving the U-shaped frame 211 and the loosening fork 212 to move up and down. The loosening fork 212 is used to loosen the soil. When it is necessary to adjust the degree of loosening according to the soil type, the threaded rod 23 is rotated to drive the moving block 24 to move back and forth. As the moving block 24 moves, it will drive the rack 25 to move, thereby driving the circular gears 214 on both sides to move. At this time, the rotation of the circular gears 214 will drive the limit rod 213 to rotate synchronously to tighten the belt 22. The degree of loosening is adjusted by controlling the speed of the loosening fork 212.

[0046] Furthermore, when the rear rotating wheel 21 rotates, it simultaneously drives the telescopic tube 31 to rotate. At this time, the rotation of the telescopic tube 31 drives the circular gear 2 32 and the bevel gear 1 33 to rotate. Simultaneously, the rotation of the wheel 4 drives the bevel gear 2 34 to rotate. Thus, when the wheel 4 drives the vehicle body 1 to move, it synchronously drives the rotating wheel 21 to rotate. When it is difficult to move the vehicle body 1 by manpower while simultaneously loosening the soil, the electric telescopic rod 35 is activated and the telescopic tube 31 is extended and retracted to drive the circular gear 2 32 to move. At this time, the circular gear 2 32 will mesh with the circular gear 3 37. Then, the motor 36 is activated to drive the circular gear 3 37 to rotate. Thus, the power of the motor 36 directly drives the rotating wheel 21 to rotate, without relying on the power of the wheel 4.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
