[0002] A tree digger is a mechanical device specially used for digging trees. It is usually used in forestry, gardening and urban greening. The main function of a tree digger is to dig out trees together with the soil at their roots for transplanting or transplanting. This equipment can greatly reduce manual labor, improve transplanting efficiency, and reduce damage to the roots of trees.

[0003] When a tree grows up, the closer its root system is to the main pole, the thicker it is, and the greater the effect on the tree. When operating an existing tree digger, the driver can only rely on his own judgment to determine the location of the tree. When transplanting a tree, the tree may not be in the center of the transplanting equipment due to visual inspection. When the tree is shoveled up, the thicker root system may be damaged, which affects the survival rate of the tree. For this reason, we propose a forestry tree transplanting device.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 , the utility model provides a technical solution: a forestry tree transplanting device, comprising a vehicle body 1, wherein the front end of the vehicle body 1 is provided with a grabbing portion 2 for transplanting trees;

[0022] The grabbing part 2 includes a slip ring 20, which is a semicircular structure design. The end of the slip ring 20 is rotatably connected with an opening and closing ring 21. The outer surfaces of the slip ring 20 and the opening and closing ring 21 are fixedly connected with shovel plates 22 for digging the land. The number of the shovel plates 22 is three groups. The corresponding positions of the slip ring 20 and the opening and closing ring 21 are provided with a positioning part 3 for preliminary positioning of the tree. Before transplanting the tree, the opening and closing ring 21 is opened, the vehicle body 1 moves to place the tree in the middle of the slip ring 20, and then the opening and closing ring 21 is closed, and the tree and the land are wrapped by the shovel plates 22;

[0023] The control unit 4 is used to connect the slip ring 20 and the vehicle body 1, and can adjust the position of the entire gripping unit 2, and cooperate with the positioning unit 3 to position the tree in the center area of ​​the gripping unit 2, thereby avoiding damage to the main root of the thick part of the tree as much as possible.

[0024] The alignment part 3 includes a hydraulic rod 30, which is fixedly connected to the annular inner surface of the slip ring 20. The opening and closing ring 21 is fixedly connected with a laser sensor 31 at the corresponding position of the hydraulic rod 30. The laser sensor 31 and the hydraulic rod 30 are aligned with each other. The hydraulic rod 30 points to the center of the slip ring 20. A target ruler 32 is fixedly connected to the position aligned with the hydraulic rod 30 above the slip ring 20. The target ruler 32 is designed as a rectangular structure. The user aligns the target ruler 32 with the tree body by visual observation on the vehicle body 1, and then resists the tree through the hydraulic rod 30. The distance of the tree is read by the laser sensor 31, and the tree is aligned when it matches the extension and contraction amount of the hydraulic rod 30. After the hydraulic rod 30 contacts the tree, the entire grasping part 2 is pushed by the hydraulic rod 30 and moves forward and backward along the front of the vehicle body 1 through the control part 4. Through the above technical solution, the tree can be placed as close to the center of the grasping part 2 as possible, and the main root of the tree is closer to the tree body, thereby minimizing the damage to the main root of the tree.

[0025] The control unit 4 includes a connecting seat 40, which is fixedly connected to the vehicle body 1. A sliding groove 41 is provided on the outer surface of one end of the connecting seat 40 away from the vehicle body 1. A slider 42 is slidably connected inside the sliding groove 41. A connecting block 45 is fixedly connected to one end of the slider 42 away from the sliding groove 41. One end of the connecting block 45 away from the sliding groove 41 is connected to the slip ring 20. A threaded rod 43 is rotatably connected to the inner surface of the sliding groove 41 through a rotating shaft. The threaded rod 43 penetrates the slider 42 and is threadedly connected thereto. A motor 33 is fixedly connected to one end of the threaded rod 43 away from the sliding groove 41. The motor 33 is fixedly connected to the connecting seat 40. When the vehicle body 1 is locked, a deviation is found through the target scale 32. The threaded rod 43 is driven to rotate by the motor 33, and the connecting block 45 is driven to move laterally by the slider 42 until the user visually sees that the target scale 32 is located in the middle of the tree. The moving connecting block 45 drives the slip ring 20 to move laterally, and then cooperates with the aligning unit 3 to place the tree in the center area of ​​the slip ring 20.

[0026] The outer surface of the lower end of the slip ring 20 is rotatably connected to the connecting block 45 at a position corresponding to the connecting block 45 through a bearing. The sliding block 46 is provided with a telescopic groove 47 matching the connecting block 45. The connecting block 45 is located inside the telescopic groove 47. The end of the connecting block 45 is fixedly connected to an electromagnet 49 magnetically attracted to the sliding block 46. A spring 48 is fixedly connected between the inside of the telescopic groove 47 and the electromagnet 49. When the hydraulic rod 30 pushes the tree, the slip ring 20 and the sliding block 46 are extended and retracted along the direction of the connecting block 45 through the telescopic groove 47. The position of the tree is determined by the laser sensor 31 and the hydraulic rod 30, and the electromagnet 49 is energized to fix the sliding block 46 and the connecting block 45. The setting of the spring 48 facilitates the resetting of the slip ring 20 and the sliding block 46.

[0027] The outer surface of the upper end of the sliding block 46 is fixedly connected to the motor 2 44, and the output end of the motor 2 44 is fixedly connected to the gear 34. The slip ring 20 and the gear 34 are provided with tooth grooves 35 at corresponding positions, and the gear 34 is meshed with the tooth grooves 35. When the shovel plate 22 is inserted into the soil, if it encounters stones, the motor 2 44 drives the gear 34 to rotate and drives the slip ring 20 to rotate a certain angle on the upper end of the sliding block 46, so as to avoid larger stones, which is beneficial to the rapid insertion of the shovel plate 22. The motor 2 44 is a self-locking motor and can be equipped with a reducer to amplify the torque (which is a prior art not shown in this article).

[0028] Working process: the vehicle body 1 controls the opening of the opening and closing ring 21, and the vehicle body 1 drives the slip ring 20 to move to the periphery of the tree under the alignment of the target scale 32, and then closes the opening and closing ring 21, and the hydraulic rod 30 pushes the tree. At this time, the slip ring 20 and the sliding block 46 slide along the telescopic groove 47. At this time, the electromagnet 49 is not energized. When the value displayed by the laser sensor 31 matches the telescopic amount of the hydraulic rod 30, the electromagnet 49 is energized to lock the overall position of the slip ring 20, completing the positioning of the tree, so that the grabbing part 2 inserts the shovel plate 22 into the ground, and then the vehicle body 1 pulls out the entire tree.
