Description

Technical Field

[0001] The utility model relates to the field of tree transplanting excavation shovels, in particular to a tree transplanting excavation shovel. Background Technique

[0002] Tree transplanting refers to the process of transplanting a mature tree from one location to another. This work is usually carried out in projects such as landscaping, urban beautification, road construction or tree protection. Tree transplanting is a highly technical task that requires careful planning and implementation to ensure that the tree can survive smoothly and grow healthily in the new environment.

[0003] Currently, during the process of tree transplanting, the method of manually excavating trees is usually adopted, which is not only time-consuming and laborious, but also has very low efficiency. In addition, although using traditional large machinery for excavation can improve work efficiency, due to the large volume and inflexibility of these machines, they are more suitable for the transplanting of large trees. For the transplanting of small to medium-sized trees, using large machinery not only results in low efficiency, but may also cause damage to the tree roots, affecting the survival rate of the transplanted trees.

[0004] Therefore, there is a particular need for an adjustable tree transplanting excavation shovel to solve the problems existing in current tree transplanting. Summary of the Invention

[0005] In order to overcome the disadvantages that during the process of tree transplanting, manual excavation has low efficiency, while using traditional large machinery for excavation is not suitable for small to medium-sized trees, resulting in low efficiency and possible damage to the tree roots, affecting the survival rate of the transplanted trees, the utility model provides a tree transplanting excavation shovel.

[0006] The present utility model is achieved through the following technical means: An arbor transplanting excavation shovel, comprising a mounting plate, a dual-axis motor, a connecting member, a first hydraulic cylinder, a rotating member, a gear, a rack, a hinge member, a second hydraulic cylinder, a connecting rod, an excavator, a bolt, a clamping plate and a return spring. The mounting plate serves as the support platform for the entire excavation shovel. The dual-axis motor is installed on the front side of the lower part of the mounting plate, and a connecting member is installed between the two output shafts of the dual-axis motor. The upper part of the connecting member is installed with a first hydraulic cylinder, and the lower part is rotatably connected with rotating members distributed left and right. On one side of the two rotating members close to each other, a gear is fixedly connected. The end of the telescopic rod of the first hydraulic cylinder is fixedly connected with a rack having the same thickness as the gear. The rack is centered between the two gears. On one side of the two rotating members away from each other, a hinge member is installed. A second hydraulic cylinder is rotatably connected to the hinge member. The lower part of the rotating rod is rotatably connected with a rotating shaft, and excavators distributed front and back are butted at both front and back ends of the rotating shaft. The upper part of the excavator is threadedly connected with a bolt, and one end of the bolt facing the second hydraulic cylinder is threadedly connected with the rotating shaft, so that the excavator is fixed on the rotating shaft. A connecting rod is rotatably connected between the upper parts of the two longitudinally aligned excavators. The end of the telescopic rod of the second hydraulic cylinder is fixedly connected with the connecting rod. A clamping plate is slidably connected to the rotating member, and at least two return springs are connected between the clamping plate and the rotating member.

[0007] In addition, particularly preferably, the excavator has a flat shovel-shaped structure, wider at the upper end and gradually narrowing at the lower end.

[0008] In addition, particularly preferably, the bolt is provided with a slotted head for adapting to a flat-blade screwdriver.

[0009] In addition, particularly preferably, a plurality of rubber strips are equidistantly distributed on the clamping surface on the downward side of the clamping plate, and at least two rubber strips are also provided on the inner side of the excavator.

[0010] In addition, particularly preferably, a guiding member for guiding the clamping plate is provided inside the rotating member.

[0011] In addition, particularly preferably, the return spring is made of high-strength spring steel or other special alloy materials.

[0012] From the above description of the structure of the present utility model, the design starting point, concept and advantages of the present utility model are as follows:

[0013] By setting the first hydraulic cylinder, the gear and the rack, the present utility model opens the first hydraulic cylinder and controls the extension or retraction of its telescopic rod, thereby rotating the left and right connecting members to a suitable angle and adjusting the excavator to a suitable position, so as to realize the size adjustment of the excavation shovel, making the excavation shovel applicable to the excavation of small, medium and even large arbors.

[0014] By providing clamping plates and return springs, when the excavator digs a tree from the soil, the tree trunk contacts the clamping plates, and the return springs apply force to the clamping plates, enabling the clamping plates to cooperate with the excavator to firmly clamp tree trunks of different diameters, thereby ensuring that the tree does not shake or fall off during the excavation process.

[0015] By providing bolts, the excavator is detachably fixed to the rotating shaft, thus facilitating the easy replacement of the excavator and improving the flexibility and practicality of the excavation shovel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0022] Embodiment: A tree transplanting excavation shovel, refer to Figures 1-4As shown in the figure, it includes a mounting plate 1, a dual-axis motor 2, a connecting piece 3, a first hydraulic cylinder 4, a rotating piece 5, a gear 6, a rack 7, a hinge piece 8, a second hydraulic cylinder 9, a connecting rod 10, an excavator 11, a bolt 12, a clamping plate 13 and a return spring 14. The mounting plate 1 serves as the support platform for the entire excavating shovel and is provided with a plurality of mounting holes distributed in a square shape for fixing the excavating shovel. The dual-axis motor 2 is installed on the front side of the lower part of the mounting plate 1, and a connecting piece 3 is connected between the two output shafts of the dual-axis motor 2 by means of bolts. The upper part of the connecting piece 3 is connected with a first hydraulic cylinder 4 by means of bolts, and the lower part is rotatably connected with rotating pieces 5 distributed left and right. On one side where the two rotating pieces 5 are close to each other, a gear 6 is connected by welding. The end of the telescopic rod of the first hydraulic cylinder 4 is connected with a rack 7 having the same thickness as the gear 6 by welding. The rack 7 is centered between the two gears 6, and the left and right sides are respectively in positive and reverse meshing with the two gears 6, so that when the rack 7 meshes with the two gears 6, the two gears 6 rotate in opposite directions. On the side where the two rotating pieces 5 are far away from each other, a hinge piece 8 is connected by means of bolts. A second hydraulic cylinder 9 is rotatably connected to the hinge piece 8. The lower part of the rotating rod is rotatably connected with a rotating shaft 501. Both the front and rear ends of the rotating shaft 501 are butted with excavators 11 distributed front and rear. The excavator 11 has a flat shovel-shaped structure, wider at the upper end and gradually narrowing at the lower end, suitable for general soil excavation. The upper part of the excavator 11 is threadedly connected with a bolt 12. The end of the bolt 12 facing the second hydraulic cylinder 9 is threadedly connected with the rotating shaft 501, so that the excavator 11 is fixed on the rotating shaft 501, and the bolt 12 is provided with a slotted head for adapting to a flat screwdriver. Between the upper parts of the two longitudinally aligned excavators 11, a connecting rod 10 is rotatably connected by welding. The end of the telescopic rod of the second hydraulic cylinder 9 is fixedly connected with the connecting rod 10. The rotating piece 5 is slidably connected with a clamping plate 13 by means of a slide rail and a slider. There is a certain distance between the two clamping plates 13 to ensure the normal rotation of the rotating piece 5. On the clamping surface of the lower side of the clamping plate 13, a plurality of rubber strips are arranged at equal intervals, and at least two rubber strips are also arranged on the inner side of the excavator 11 to improve the clamping effect. Inside the rotating piece 5, a guiding piece for guiding the clamping plate 13 is provided to improve the smoothness of the sliding of the clamping plate 13. At least two return springs 14 are connected between the clamping plate 13 and the rotating piece 5. The return springs 14 are made of high-strength spring steel or other special alloy materials to provide stronger elastic force and supporting force.

[0023] When a digging shovel is needed, first, the staff installs the mounting plate 1 on the boom of the excavator to ensure firm installation. Then, the first hydraulic cylinder 4 is turned on, and its telescopic rod is controlled to extend or retract. When the telescopic rod extends, it drives the rack 7 to move downward, meshing with the two gears 6 in the forward and reverse directions respectively. During the meshing process, the left gear 6 drives the left rotating member 5 to rotate clockwise, and the right gear 6 drives the right rotating member 5 to rotate counterclockwise. On the contrary, when the telescopic rod shortens, it drives the rack 7 to move upward, meshing with the two gears 6 in the reverse and forward directions respectively. During the meshing process, the left gear 6 drives the left rotating member 5 to rotate counterclockwise, and the right gear 6 drives the right rotating member 5 to rotate clockwise. When the connecting members 3 on both the left and right sides rotate to the appropriate angles and the excavator 11 is adjusted to the appropriate position, the first hydraulic cylinder 4 is turned off. Then, the excavator is controlled to the side of the tree to be transplanted. The dual-axis motor 2 is turned on, and its two output shafts drive the connecting members 3 to rotate simultaneously, so that the excavator 11 rotates to the appropriate angle. When the tree trunk is avoided from touching the ground, the dual-axis motor 2 is turned off. Then, the second hydraulic cylinder 9 is turned on, and its telescopic rod is controlled to extend, thereby driving the connecting rod 10 to drive the excavator 11 to rotate inward and shovel into the soil to loosen the roots of the tree. After the excavator 11 rotates to the appropriate angle to complete shoveling, the second hydraulic cylinder 9 is turned off. Then, the dual-axis motor 2 is turned on again, and its output shaft drives the connecting members 3 to rotate to the horizontal state, so that the excavator 11 digs out the roots of the tree from the soil. During this process, the tree trunk touches the clamping plate 13, and the return spring 14 applies a force to the clamping plate 13, so that the clamping plate 13 and the excavator 11 cooperate to firmly clamp the tree trunks of different diameters. Thus, the entire digging process of the tree is completed. The dual-axis motor 2 is turned off. Finally, the second hydraulic cylinder 9 is turned on again, and its telescopic rod is controlled to retract, thereby driving the connecting rod 10 to drive the excavator 11 to rotate outward to loosen the tree trunk. Then, the second hydraulic cylinder 9 is turned off, which is convenient for later placing the tree at the transplanting site.
