Description

Technical Field

[0001] The invention relates to the technical field of transplanting, and in particular to a forestry seedling transplanting device. Background Art

[0002] In the forestry field, for a long time, the transplanting of shrub seedlings has mostly relied on manual operations. The traditional manual transplanting method usually uses simple tools (such as shovels and hoes) to dig around the roots of the shrub seedlings, trying to dig out a soil ball with a certain root system and soil, and then relies on manpower to transport it to the transplanting site for planting. However, there are many problems with this method. On the one hand, it is difficult to accurately control the shape and size of the soil ball by manual excavation, which can easily cause root damage and affect the survival rate of shrub seedlings after transplanting; on the other hand, the excavation efficiency is low, especially in large-scale transplanting work, which consumes a lot of manpower and time, and increases labor costs. Moreover, during the transportation process, due to the lack of effective protective measures, it is easy to cause the soil ball to loosen and the branches of the shrub to break, further reducing the success rate of transplanting.

[0003] With the development of forestry mechanization, some mechanical equipment for seedling transplanting has also appeared, but it can only realize basic digging functions, and the overall structure and effect are relatively simple.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1, as Figure 1 As shown, a forestry seedling transplanting device includes a workbench body 1, two lifting arms 11 are arranged at the front end of the body 1, and hydraulic devices are arranged at the rear ends of the two lifting arms 11 to facilitate the lifting and lowering activities thereof. The two lifting arms 11 are rotatably connected to a connecting seat 12 on the sides close to each other, a rotating assembly 2 is arranged at the lower ends of the two connecting seats 12, a protective assembly 3 is arranged at the middle position of the rotating assembly 2, a loosening assembly 4 is symmetrically arranged at the lower end of the rotating assembly 2, a soil cutting assembly 5 is symmetrically arranged at the lower end of the rotating assembly 2, and a clamping assembly 6 is symmetrically arranged on the outer surface of the rotating assembly 2.

[0035] During the operation of this embodiment, the simultaneous implementation of multiple processes such as loosening the soil, cutting the soil, clamping, and protective winding of the transplanted plants is achieved through the synchronous rotation of the rotating component 2. Among them, the loosening component 4 and the cutting component 5 rotate in the same direction, forming a work process of loosening the soil first and then cutting the soil, making the excavation process smoother, and using the clamping component 6 to change the angle of the cutting component 5 when it rotates, ensuring that the soil ball is completely dug out, reducing the risk of damage, and overall improving the transplanting efficiency, ensuring the integrity of the shrubs and the quality of transplanting.

[0036] Embodiment 2: Based on embodiment 1, this embodiment is to achieve the effects of simultaneously completing the loosening, digging and protection of shrub seedlings.

[0037] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The rotating assembly 2 includes a fixed seat 21 fixedly connected to the lower ends of the two connecting seats 12, the lower end of the fixed seat 21 is fixedly connected to a fixed seat 22, the top wall of the inner surface of the fixed seat 21 is provided with a limiting groove 211, the side wall of the inner surface of the fixed seat 21 is provided with a limiting groove 212, the limiting groove 211 and the limiting groove 212 play a limiting role, the upper end of the fixed seat 21 is fixedly connected to a motor 23, and the output end of the motor 23 is fixedly connected to a gear 24.

[0038] The outer surface of gear 1 24 is meshedly connected with a ring gear 25, the upper end of the ring gear 25 is fixedly connected to a limiting seat 251, the outer surface of the limiting seat 251 is rotatably connected to the limiting groove 1 211, and the ring gear 25 can be limited to allow it to rotate stably. The lower end of the ring gear 25 is fixedly connected to a base 252, and the base 252 rotates with the ring gear 25.

[0039] The inner surface of the limiting groove 212 is rotatably connected with the inner ring gear 26, and the side of the gear 1 24 away from the ring gear 25 is meshed with the inner ring gear 26. The lower end of the inner ring gear 26 is fixedly connected with a connecting plate 27, and the rotation directions of the ring gear 25 and the inner ring gear 26 are opposite.

[0040] Then, the vehicle body 1 is controlled to move it to the specified position, and the hydraulic device is controlled to make the lifting arm 11 drive the fixing seat 21 to descend as a whole, and the shrub seedling is placed on the center position of the fixing seat 21. At this time, the fixing seat 21 is located at the branch on the lower side of the shrub seedling, and then the motor 23 is started to drive the gear 24 to rotate counterclockwise, so that the inner ring gear 26 rotates counterclockwise and the ring gear 25 rotates clockwise.

[0041] See also Figure 4 , Figure 5 and Figure 7 The protection component 3 includes four hooks 31 fixedly connected to the inner surface of the base 252, and the outer surfaces of the four hooks 31 are all sleeved with ropes 32, and the top ends of the four ropes 32 are commonly fixedly connected with a protection net 33.

[0042] Furthermore, when the base 252 rotates, the rope 32 is wrapped around the branches of the shrub seedlings, and the protective net 33 forms a simple but effective protective structure for the shrub seedlings, which can effectively buffer and disperse the external forces exerted on the branches of the shrub seedlings during the excavation, transportation and transplanting process, such as vibration, shaking, collision, etc., and significantly reduce the risk of branch breakage and damage.

[0043] The size, elasticity and other parameters of the protective net 33 can be flexibly adjusted according to the shape and size of different shrub seedlings. It can not only play a protective role, but also will not cause too much restriction on the growth of shrub seedlings. It can adapt to various shrub seedlings of different shapes and can play a good protective role in different woodland environments, further improving the versatility and practicality of the transplanting device.

[0044] Among them, the protective net 33 is elastic and will not cause damage to the shrub seedlings. When the rope 32 is wrapped around the shrub seedlings, its position is located at the branches of the shrub seedlings, and the protective net 33 is put on the outer surface of the shrub seedlings. The rope 32 can be directly removed or hung up manually, making the replacement of the protective net 33 quick and convenient.

[0045] Furthermore, when the fixing seat 21 is located at the branches on the lower side of the bush seedling, the protective net 33 is in a state of being sleeved on the outer surface of the bush seedling. When the ring gear 25 rotates clockwise, it will drive the hook 31 and the rope 32 to rotate clockwise, and simply wrap the branches at the bottom of the bush seedling to prevent the protective net 33 from separating from the bush seedling. Then the rope 32 can be removed manually to allow the protective net 33 to remain on the surface of the bush seedling to protect it.

[0046] See also Figure 1 , Figure 2 and Figure 8 The loosening assembly 4 includes a connecting column 41 fixedly connected to the lower end of the connecting plate 27, the lower end of the connecting column 41 is fixedly connected to a support seat 42, the inner surface of the support seat 42 is rotatably connected to a gear 2 43, the outer surface of the gear 2 43 is meshed with the ring gear 25, and the lower end of the gear 2 43 is fixedly connected to a threaded drill 44.

[0047] Furthermore, the connecting column 1 41, the supporting seat 42 and the gear 2 43 all rotate counterclockwise along with the inner ring gear 26 and the connecting plate 27, so that the screw drills 44 on both sides first contact the soil. The length of the screw drill 44 is greater than the length of the cutter 53, so the screw drill 44 will first drill into the soil, stir up the surrounding soil, push the originally compacted soil particles outward, destroy the tight connection between the soil particles, and make the soil loose and porous.

[0048] Further, from Figure 8 It can be seen that there is a small error between the running trajectory of the threaded drill 44 and the running trajectory of the cutter 53, but the spiral structure on the threaded drill 44 will stir and crush the soil in its surrounding area and push the soil outward, so it can still reduce the pressure of the cutter 53 when cutting the soil.

[0049] Furthermore, in the process of the lifting arm 11 driving the fixing seat 21 to descend as a whole, the threaded drill 44 and the cutter 53 will be inserted into the soil, and after starting the motor 23, the inner ring tooth 26 will rotate counterclockwise along with the gear 24, thereby driving the connecting plate 27, the connecting column 1 41, the support seat 42 and the gear 2 43 to rotate counterclockwise together. Synchronously, the gear 2 43 will mesh with the ring gear 25 while rotating around the connecting plate 27, so that the gear 2 43 will rotate during the revolution, so that the threaded drill 44 will move counterclockwise while rotating, thereby breaking up the soil.

[0050] See also Fig. 9 , Fig.10 and Fig.11 The soil cutting assembly 5 includes a second connecting column 51 rotatably connected to the lower end of the connecting plate 27 , a fixing block 52 is rotatably connected to the outer surface of the connecting column 51 , and a cutting knife 53 is provided at the lower end of the fixing block 52 .

[0051] Furthermore, the two cutting knives 53 both make a half circle counterclockwise along the soil around the shrub seedling, thereby cutting out a whole soil ball.

[0052] See also Figure 1 , Figure 2 , Fig.10 and Fig.11 The clamping assembly 6 includes a gear three 61 fixedly connected to the outer surface of the connecting column 2 51 , and an arc-shaped rack 62 is fixedly connected to the side wall of the inner surface of the fixing seat 2 22 , and the outer surface of the arc-shaped rack 62 is meshed with the gear three 61 .

[0053] Furthermore, when gear three 61 is meshed with the arc-shaped rack 62, the angle of the cutter 53 can be changed, so that the two cutters 53 are tilted toward the bottom of the shrub seedling at the same time, thereby cutting it into an inverted cone-shaped soil ball. This shape is compatible with the natural distribution characteristics of the root system of the shrub seedling, and can better wrap the root system, reduce the exposure, damage and shedding of the root system during the excavation process, and lay a good foundation for the growth of the root system of the shrub seedling in the new environment after subsequent transplantation.

[0054] A bevel gear transmission group 63 is fixedly connected to the lower end of the connecting column 51 and located inside the fixed block 52. A rotating shaft 64 is fixedly connected to the side of the bevel gear transmission group 63 away from the connecting column 51. A rotating seat 65 is fixedly connected to both ends of the rotating shaft 64 and located outside the fixed block 52.

[0055] Furthermore, the bevel gear transmission group 63 mentioned above is composed of two bevel gears meshing with each other, and when the gear three 61 rotates, it can drive the cutter 53 to change its angle.

[0056] A slot 66 is provided on the upper side of the outer surface of the cutter 53 , and three support rods 67 are provided on the outer surface of the fixing seat 22 . The lower ends of the three support rods 67 are fixedly connected to an arc-shaped limit seat 68 , and the outer surface of the arc-shaped limit seat 68 is slidably connected to the support rod 67 .

[0057] When the gear three 61 is disengaged from the arc-shaped rack 62, the slot 66 will contact the arc-shaped rack 62, so that the cutter 53 still maintains this angle in the subsequent rotation and always fits with the soil ball. After the excavation of the soil ball is completed, the close fit between the cutter 53 and the soil helps to directly pick up the soil ball and carry out subsequent transportation operations without the need for additional complex adjustments or fixing steps, thereby achieving a seamless connection between the excavation and transportation links, further optimizing the transplanting process, and improving overall work efficiency.

[0058] Furthermore, when the threaded drill 44 revolves along with the connecting plate 27, the cutter 53 also rotates along with it to cut the soil around the shrub seedlings, and the threaded drill 44 will first disperse the soil. Synchronously, when the cutter 53 moves counterclockwise along with the connecting plate 27, the gear three 61 will mesh with the arc-shaped rack 62, thereby driving the gear three 61 to rotate clockwise, and the bevel gear transmission group 63 rotates along with it to drive the rotating shaft 64 to rotate counterclockwise, so that the rotating seat 65 drives the cutter 53 to tilt toward the middle of the shrub seedlings. As the angle changes, the cutter 53 as a whole also rotates with the connecting plate 27. When the angle of the cutter 53 is tilted to the moving position, the gear 3 61 is disengaged from the arc-shaped rack 62. At the same time, the slot 66 contacts the arc-shaped limit seat 68. The arc-shaped limit seat 68 limits the slot 66 and the cutter 53, so that the soil can still be cut according to the previously changed angle when it is disengaged from the arc-shaped rack 62. In addition, the lifting arm 11 can be controlled to lift upward in this limited state, so that the shrub seedling can be dug out as a whole for transplanting.

[0059] Because the loosening component 4, the soil cutting component 5 and the clamping component 6 are all symmetrically arranged, it only needs to rotate half a circle to dig out the bush seedlings. Similarly, the reverse half a circle can open the cutter 53 to place the bush seedlings at other required transplanting positions.

[0060] Therefore, in this solution, the different directions of the rotating component 2 drive the cutter 53 and the threaded drill 44 to rotate counterclockwise, while the threaded drill 44 produces self-rotation, which reduces the compactness of the soil and the resistance of the cutter 53 to move in the soil, reduces the interruption of excavation and damage to the soil ball caused by soil problems, and the cutter 53 will change its angle during the rotation process to cut out the soil ball completely. At the same time, the protective net 33 is also driven to wrap around the periphery of the shrub seedlings in this process to protect them. The entire process has high continuity, which improves the overall quality of the shrub seedling transplanting work.

[0061] It should be noted that the specific installation method of the motor 23, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0062] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
