Description

Technical Field

[0001] The present invention relates to the technical field of forestry planting, and particularly relates to a sapling transplanting device for uprooting saplings based on forestry planting. Background Art

[0002] In the field of forestry planting, sapling transplantation is a core link in promoting the sustainable development of forest resources and optimizing the vegetation layout. It not only concerns the improvement of the vegetation coverage rate of newly afforested land, but also plays a key role in maintaining the diversity of the ecosystem, enhancing the carbon sequestration capacity, and increasing economic benefits. With the development of modern forestry towards large-scale and intensive directions, higher requirements are put forward for the efficiency and quality of sapling transplantation, requiring rapid completion of transplantation operations while ensuring the survival rate of saplings.

[0003] Based on the above, the existing sapling uprooting and transplanting devices for forestry planting have the following deficiencies: When carrying out the operation of uprooting saplings, manually uprooting saplings requires digging a circle of soil around the saplings, with high labor intensity and low uprooting efficiency. When using an uprooting device, after positioning the sapling location, due to the need to dig around the sapling, it is difficult for the device to move near the sapling under complex terrain conditions, greatly affecting the efficiency of uprooting saplings and subsequent transplantation operations. Moreover, due to different uprooting depths, the height of the transplanting and uprooting equipment cannot be adjusted flexibly and accurately, so it is impossible to effectively locate the soil area at the root of the sapling, and it is easy to damage the root system of the sapling during the uprooting process, and it is impossible to effectively wrap the soil at the root of the sapling into a stable soil ball, reducing the survival rate of the saplings after transplantation. Summary of the Invention

[0004] The present invention relates to a sapling transplanting device for uprooting saplings based on forestry planting. When the reduction motor starts, it drives the control gear to rotate, and then makes the uprooting arc frame rotate around the inner axis of the transplanting support, so that the uprooting arc frame can quickly carry out the uprooting operation around the sapling in a stable posture. The unique circular arc triangular design of the uprooting shovel, and the left and right side walls are blade-shaped, which can not only cut the soil well, but also its arc structure fits the growth form of the root system, reducing extrusion damage. Multiple uprooting shovels work together to wrap the soil at the root of the sapling into a stable soil ball, ensuring a stable root environment during transplantation.

[0011] Furthermore, a combined hinge end is fixedly installed at the top of the outer side wall of the cylinder body of the tilting control cylinder. The combined hinge end is connected to the combined hinge seat on the outer side of the cylinder body of the lifting control cylinder. The bottom of the telescopic end of the tilting control cylinder is fixedly connected to a secondary hinge end.

[0012] Furthermore, the digging shovel is in the shape of a circular arc triangle. The left and right side walls of the digging shovel are both in the shape of blades.

[0028] Embodiment 1: Please refer to Figures 1 to 8 as shown: The present invention provides a sapling transplanting device for uprooting saplings based on forestry planting, including a transplanting support 1; a lifting wheel frame 3 is slidably connected to the front and rear side walls of the transplanting support 1, a lifting main cylinder 2 is fixedly connected to the top of the lifting wheel frame 3, a digging arc frame 4 is rotatably connected to the inside of the transplanting support 1, lifting control blocks 7 are symmetrically slidably connected to the front and rear outer side walls of the digging arc frame 4, a lifting control cylinder 8 is fixedly installed on the top of the lifting control block 7, a turning control cylinder 9 is hinged to the outside of the lifting control cylinder 8, a digging shovel 10 is hinged to the outer end of the lifting control block 7, and three control gears 5 are meshed and connected to the top of the outer side wall of the digging arc frame 4 in an equidistant and circumferential manner.

[0029] Among them, two rectangular long strip-shaped sliding guide grooves 101 are symmetrically opened at the bottom of the front and rear side walls of the transplanting support 1, a gear bin 102 is opened at the inner top of the transplanting support 1, three control gears 5 are rotatably connected in the gear bin 102 in a circumferential manner, a reduction motor 6 is fixedly installed at the bottom left of the transplanting support 1, and the drive shaft of the reduction motor 6 is meshed and connected to the control gear 5 in the gear bin 102.

[0030] Among them, sliding guide blocks 301 are fixedly connected to the left and right ends of the opposite side walls of the two lifting wheel frames 3, the sliding guide blocks 301 are slidably connected in the sliding guide grooves 101 of the transplanting support 1, auxiliary baffle plates 302 are fixedly connected to the ends of the opposite side walls of the two sliding guide blocks 301, the auxiliary baffle plates 302 are slidably connected to the inner wall of the transplanting support 1, and power wheels 303 are installed at the bottom of the opposite side walls of the two lifting wheel frames 3.

[0031] By adopting the above technical solution, by connecting the telescopic end of the lifting main cylinder 2 to the lifting wheel frame 3, the lifting and lowering of the lifting wheel frame 3 can be controlled, so as to flexibly adjust the height of the transplanting support 1 according to the height and root depth of the sapling, ensure that the transplanting support 1 can accurately reach the soil area at the root of the sapling, thereby adjusting the initial positions of the digging arc frame 4 and the digging shovel 10, making it easier for the cooperation of the digging arc frame 4 and the digging shovel 10 to dig out the sapling. At the same time, the power wheels 303 installed on the lifting wheel frame 3 can contact the ground under the drive of the lifting main cylinder 2, enabling the entire sapling transplanting device to have a certain lifting and moving ability during the transplanting process, facilitating approaching the sapling under different terrain conditions, enhancing the terrain adaptability of the device, and moving to the planting position after the sapling is dug out.

[0032] Among them, the digging arc frame 4 is in the shape of a cylinder with an opening on the right side, a control rack 401 is fixedly installed on the top of the outer side wall of the digging arc frame 4, the control rack 401 is meshed and connected to the control gear 5, an auxiliary bottom plate 402 is fixedly installed on the outer side wall of the digging arc frame 4 at the bottom of the control rack 401, the bottom of the auxiliary bottom plate 402 is slidably connected to the bottom of the gear bin 102 of the transplanting support 1, and a connection end 403 is fixedly installed on the outer side wall of the digging arc frame 4 at the bottom of the auxiliary bottom plate 402, and the connection end 403 is located outside the bottom of the gear bin 102.

[0033] With the above technical solution, the reduction motor 6 at the left bottom of the transplanting support 1 is connected to the control gear 5, which can stably transmit the power of the reduction motor 6 to the digging arc frame 4. When the reduction motor 6 is started, it drives the control gear 5 to rotate. Since the control gear 5 meshes with the control rack 401, the digging arc frame 4 is driven to rotate around the inner axis of the transplanting support 1. The sliding fit between the auxiliary bottom plate 402 and the bottom of the gear bin 102 provides stable support for the rotation of the digging arc frame 4, preventing it from shifting or shaking during rotation. The connecting end 403 provides a connection basis for the lifting control cylinder 8, ensuring the stability of the subsequent lifting and flipping control structure of the digging shovel 10, so that the digging arc frame 4 can dig around the sapling in a stable posture, making the sapling digging process faster.

[0034] Among them, lifting sliding grooves 404 are formed in the front and rear outer side walls of the digging arc frame 4. The cross-section of the lifting sliding grooves 404 is in a "T" shape. A lifting slider 701 is arranged on one side of the outer side wall of the digging arc frame 4 where the lifting control block 7 is slidably connected. The lifting slider 701 is slidably connected in the lifting sliding grooves 404. A main hinge end 702 is fixedly installed at one end of the lifting control block 7 away from the digging arc frame 4.

[0035] Among them, the top telescopic end of the lifting control cylinder 8 is fixedly connected to the bottom of the connection end 403 on the outer side wall of the digging arc frame 4, and a combined hinge seat 801 is fixedly installed at the top of the outer side wall of the cylinder body of the lifting control cylinder 8.

[0036] Among them, a combined hinge end 901 is fixedly installed at the top of the outer side wall of the cylinder body of the flipping control cylinder 9. The combined hinge end 901 is connected to the combined hinge seat 801 on the outer side of the cylinder body of the lifting control cylinder 8. The bottom of the telescopic end of the flipping control cylinder 9 is fixedly connected to a secondary hinge end 902.

[0037] Among them, the digging shovel 10 is in the shape of a circular arc triangle. The left and right side walls of the digging shovel 10 are both blade-shaped. A main hinge seat 1001 is fixedly installed at the top of the outer side wall of the digging shovel 10. The main hinge seat 1001 is hinged to the main hinge end 702 of the lifting control block 7. A secondary hinge seat 1002 is fixedly connected to the outer side wall of the digging shovel 10 at the bottom of the main hinge seat 1001. The secondary hinge seat 1002 is hinged to the secondary hinge end 902 at the bottom of the telescopic end of the flipping control cylinder 9.

[0038] With the above technical solution, the lifting control block 7 is slidably connected to the lifting chute 404 of the digging arc frame 4 through the lifting slider 701. Under the telescopic action of the lifting control cylinder 8, it can slide up and down along the side wall of the digging arc frame 4, so that the digging shovel 10 can adjust its vertical position as required. For example, it extends when deeply digging and contracts when preparing to lift, realizing the effective digging and wrapping of soils at different depths. At the same time, the combined hinge seat 801 outside the cylinder body of the lifting control cylinder 8 is connected to the combined hinge end 901 of the flipping control cylinder 9, and the secondary hinge end 902 of the flipping control cylinder 9 is hinged to the secondary hinge seat 1002 of the digging shovel 10, forming a flexible angle transmission structure. When digging, the flipping control cylinder 9 extends to make the digging shovel 10 flip inward to cut the soil. After completion, the flipping control cylinder 9 is controlled to contract to make it flip outward and open, facilitating the complete removal of the soil ball wrapped around the root system of the sapling and avoiding secondary damage. In addition, the unique arc-shaped triangular design of the digging shovel 10, with blade-shaped side walls on both left and right, can not only cut the soil well, but also the arc structure conforms to the growth form of the root system, reducing extrusion damage. Multiple digging shovels 10 working together can wrap the soil at the root of the sapling into a stable soil ball, ensuring the stability of the root environment during transplantation and greatly improving the survival rate of the sapling after transplantation.

[0039] Specific usage mode and function of this embodiment: In the present invention, first move the device near the sapling to be transplanted. Control the lifting wheel frame 3 to rise through the lifting main cylinder 2, so that the driving wheel 303 leaves the ground and the transplantation support 1 contacts the ground to ensure that the transplantation support 1 is in a suitable position. Then, send the digging shovel 10 into the soil at a suitable depth through the lifting control cylinder 8 and the lifting control block 7. Next, start the flipping control cylinder 9 to extend and push the digging shovel 10 to flip inward to cut the soil. Then, start the reduction motor 6 to drive the digging arc frame 4 to rotate around the inner axis of the transplantation support 1 to form a circular enclosure. As the digging shovel 10 follows the digging arc frame 4 to rotate and cut the soil, the soil at the root of the sapling is wrapped into a ball. After completion of the wrapping, control the lifting wheel frame 3 to descend through the lifting main cylinder 2, and use the driving wheel 303 to contact the ground to separate the device together with the sapling from the ground. Then transfer it to the planting pit at the target planting location. Next, reverse-start the flipping control cylinder 9 to contract, so that the digging shovel 10 flips outward and opens, gently place the soil ball into the planting pit, and remove the digging shovel 10 to complete the sapling transplantation work.
