Description

Technical Field

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

[0002] At present, forestry seedling transplanting has developed a mature technical system. During the transplanting process, professional mechanical equipment such as hydraulic four-petal tree transplanters and crawler soil ball tree huggers are widely used. They can efficiently and accurately complete tasks such as soil ball excavation, lifting and transportation, significantly reducing damage to the root system of seedlings.

[0003] When digging the soil ball, the existing transplanting device directly digs the shovel into the soil, and then lifts the soil ball and seedlings. This can easily pull the roots of the seedlings, causing damage to the soil ball and seedlings, affecting the survival rate. In addition, when the shovel digs into the soil, the soil is squeezed hard, which makes it difficult for the soil ball to maintain its shape, affecting the protection of the soil ball to the seedling roots. In addition, the support effect on the seedlings during digging is poor, resulting in tilting.

[0004] In view of the above problems, the present invention provides a forestry seedling transplanting device to solve the above problems. Summary of the Invention

[0015] Reference Figure 1-Figure 4 The present invention provides a technical solution: a forestry seedling transplanting device, comprising: a vehicle body having a lifting device fixed to one end thereof; Connecting seat 1, fixed to the output end of the lifting device; A positioning ring is rotatably arranged at one end of the connecting base 1 away from the lifting device, and the positioning ring includes a positioning ring 1 2 and a positioning ring 2 3. The positioning ring 1 2 is hinged to one end of the positioning ring 2 3, and an opening and closing cylinder 4 is installed at the hinge position; The transplanting components 5 are configured as three and arranged circumferentially on the positioning ring; A driving assembly 6 is mounted on the connecting seat 1 and the positioning ring; There are at least two clamping assemblies 7 , which are slidably arranged on the driving assembly 6 .

[0016] It should be noted that the clamping components 7 are at different heights, so as to perform staggered clamping on the branches of the seedlings, realize the transmission of dispersed force in an asymmetric layout, reduce the concentration of local force, and improve the clamping effect.

[0017] In this embodiment, the transplanting assembly 5 includes: A lifting frame 51, one end of which is hinged to the positioning ring and a lifting cylinder is fixed inside the lifting frame; An adjusting cylinder 52, one end of which is hinged to the lifting frame 51, and the other end of which is hinged to the positioning ring; The shovel 53 is slidably disposed on the lifting frame 51 and connected to the output end of the lifting cylinder.

[0018] As a preferred embodiment, a cutting edge 54 is provided on the side wall of the shovel 53 , and when the shovel 53 is in a vertical state, the rotational trajectory of the plurality of shovels 53 is circular.

[0019] Among them, when excavating, the shovel 53 is initially vertically downward. At this time, the shovel 53 is made to enter the soil through the lifting cylinder, and then the shovel 53 is made to reciprocate through the driving component 6, thereby cutting the roots of the seedlings to avoid pulling the roots of the seedlings. After the initial excavation, the soil around the seedlings is a columnar structure. At this time, the bottom of the columnar structure is in a connected state with the soil, completing the initial excavation, avoiding the excavation point being too close to the soil ball to be formed, squeezing the soil ball, affecting the compaction of the soil, and then the shovel 53 adjusts the angle by adjusting the cylinder 52, so that the shovel 53 is retracted when sliding, thereby trimming the columnar soil, completing the excavation of the soil ball, and reducing the squeezing force on the soil ball.

[0020] In this embodiment, the driving assembly 6 includes: A fixing base 61 is fixed to the upper end of the connecting base 1, and a driving motor is fixed to the bottom of the connecting base 1; A driving gear 62 is rotatably mounted on the fixing base 61 and driven by a driving motor; The half gear 63 is fixed on the positioning ring and is hinged to the driving gear 62; The guide plate 65 is fixed to one end of the fixing base 61 close to the half gear 63 .

[0021] That is, the driving gear 62 drives the half gear 63 to rotate, and drives the positioning ring to rotate, so that the shovel 53 is adjusted in position to complete the cutting of the root system and the trimming of the soil ball.

[0022] As a preferred embodiment, a guide groove 64 is provided on the top of the half gear 63 , and a plurality of guide wheels 66 are rotatably provided on the lower end surface of the guide plate 65 , and the plurality of guide wheels 66 are rollingly provided in the guide groove 64 .

[0023] The guide groove 64 and the guide wheel 66 of the driving gear 62 can guide the half gear 63 , so that the half gear 63 and the driving gear 62 can be better meshed and transmitted.

[0024] As a preferred embodiment, a threaded rod 68 is rotatably provided on the fixing seat 61 , the threaded rod 68 is fixedly connected to the driving gear 62 , and a guide rod 67 is fixed to the upper end surface of the guide plate 65 .

[0025] As a preferred embodiment, the clamping assembly 7 includes: A sliding plate 71 has a sliding groove 72 at one end thereof, the sliding groove 72 being slidably disposed on the guide rod 67 , and a nut 73 being rotatably disposed within the other end of the sliding plate 71 , the nut 73 being threadedly connected to the threaded rod 68 ; a clamping rod 75 hinged on the guide rod 67 and hinged to the sliding plate 71; A clamping cylinder 76 , one end of which is hinged to the sliding plate 71 and the other end of which is hinged to the clamping rod 75 ; a flexible wheel 77 rotatably disposed at one end of the clamping rod 75 away from the sliding plate 71 , and a torsion spring is disposed between the flexible wheel 77 and the clamping rod 75 ; The clamping plate 78 is an arc-shaped structure and is fixed on the flexible wheel 77 .

[0026] As a preferred embodiment, a limiting cylinder 74 is fixed at the outer wall of the sliding plate 71 and the corresponding position of the nut 73 , and the output end of the limiting cylinder 74 extends into the sliding plate 71 and contacts the outer wall of the nut 73 for limiting position.

[0027] That is to say, when the output end of the limiting cylinder 74 contacts the nut 73 to limit the position, the threaded rod 68 rotates, and the nut 73 slides up and down through the threaded connection, thereby adjusting the height of the clamping plate 78 and performing staggered clamping corresponding to seedlings of different heights. When the output end of the limiting cylinder 74 does not contact the nut 73, the nut 73 can rotate in the sliding plate 71. At this time, the threaded rod 68 rotates, and the nut 73 rotates synchronously with the threaded rod 68, avoiding vertical displacement during the clamping operation and improving the clamping effect.

[0028] Specifically, when transplanting seedlings, the shovel 53 is kept in a vertical state to perform preliminary excavation around the seedlings, thereby forming columnar soil. During excavation, the shovel 53 is driven by the driving component 6 to rotate back and forth, which is convenient for cutting the root system. Afterwards, the shovel 53 is adjusted and retracted to trim the columnar soil to form a semicircular soil ball, thereby reducing the squeezing force on the soil ball during excavation, avoiding changing the compactness of the soil in the soil ball and affecting the survival rate. During excavation, the branches and trunks of the seedlings can be staggered and clamped by multiple clamping components 7, which can more effectively resist torques from different directions and enhance the clamping effect.

[0029] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
