Description

Technical Field

[0001] This utility model relates to the field of sapling raising technology in landscaping, specifically a sapling raising device for landscape trees. Background Technology

[0002] Landscape trees are used in garden landscape design to beautify the environment and create landscape effects. These trees not only have ornamental value, but also provide a variety of ecological functions such as providing shade, improving air quality, and reducing noise. Many trees have special symbolic meanings in different cultures. After the landscape tree seedlings are cultivated, they will be transplanted from the nursery or growing site to the predetermined location in the garden landscape to beautify the environment and enhance the ornamental value of the garden.

[0003] A related technology (publication number: CN205093295U) discloses a seedling lifting device for garden trees. The disclosed technical solution is as follows: starting a gasoline engine, the gasoline engine drives the transmission shaft to rotate, and the transmission shaft drives the active bevel gear to rotate. Since the active bevel gear and the driven bevel gear mesh with each other, the driven bevel gear can drive the rotating shaft and cam to rotate. When the cam rotates, it can intermittently strike the movable plate and move it downward. Under the action of the spring, the movable plate moves upward, thus achieving high-frequency vibration of the lifting shovel. When the lifting shovel vibrates at high frequency, it can quickly penetrate into the root of the seedling, thereby lifting the seedling and the soil together. The device has a simple structure and powerful function, replacing the traditional method of lifting seedlings by hand. Moreover, the seedling is covered with soil when it is lifted, thus not only improving the efficiency of lifting seedlings, but also protecting the seedlings.

[0004] The above-disclosed technical solutions reveal the following problems: After the soil is excavated, the seedlings need to be removed from the cultivation site. During this process, different types of seedlings have different heights. Therefore, when lifting the seedlings, it is necessary to ensure that the force point is located at the center of gravity of the seedling to prevent the seedlings from falling off during the lifting process. In response, we have proposed a seedling lifting device for landscape trees.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Utility Model Content

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the problem of landscape tree uprooting in the prior art, this utility model provides a landscape tree uprooting device that combines an uprooting structure with an uprooting position adjustment structure to improve uprooting efficiency. Its specific technical solution is as follows:

[0007] A landscape tree lifting device includes a movable base. The top of the movable base is provided with a center of gravity adjustment component for adjusting the lifting and gripping position. The output end of the center of gravity adjustment component is provided with a displacement frame. A propulsion frame is provided on the front side of the displacement frame, and a propulsion component for adjusting the lateral displacement of the propulsion frame is provided on the displacement frame. Supports are symmetrically fixed to the front side of the propulsion frame. Each support is provided with a lifting gripper that rotates in opposite directions, and a reverse linkage component is provided on the support to drive the lifting gripper to grab the tree seedling.

[0008] In the above technical solution, the reverse linkage component includes a driving bevel gear rotatably mounted on the bracket, and driven bevel gears are symmetrically mounted on the outer wall of the driving bevel gear. The driven bevel gears are outside the movable shaft, and the movable shaft is rotatably mounted inside the bracket. The seedling lifting gripper is sleeved on the outside of the movable shaft.

[0009] The inner wall of the seedling grabber is evenly provided with protective pads.

[0010] The center of gravity adjustment assembly includes an adjustment screw that is rotatably mounted longitudinally on the top of the movable seat, and the displacement frame is threaded to the outside of the adjustment screw.

[0011] A directional guide rod parallel to the adjusting screw is fixedly installed on the top of the movable seat, and the displacement frame is sleeved on the outside of the directional guide rod.

[0012] The propulsion assembly includes a propulsion screw rotatably disposed on the rear side of the displacement frame. The external thread of the propulsion screw is connected to a push seat. The push seat is connected to the propulsion frame via a connecting rod that passes through the inner cavity of the displacement frame.

[0013] The positions of the directional guide rod and the connecting rod are offset from each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the seedling lifting device for landscape trees:

[0015] 1. The longitudinal position of the displacement frame is adjusted by the center of gravity adjustment component on the moving seat. The position of the displacement frame is adjusted according to the height of the sapling to ensure that the lifting clamp is at the center of gravity of the sapling. This ensures the stability of the sapling during the process of pulling it out of the soil and provides protection during the lifting process. The height of the lifting clamp can be adjusted according to the height of the sapling by the center of gravity adjustment component, making it suitable for saplings of different heights and applicable to various situations.

[0016] Second, the propulsion component located on the displacement frame enables the seedling lifting clamps to move laterally, ensuring that the two seedling lifting clamps move to both sides of the seedling. The position of the two seedling lifting clamps is adjusted according to the position of the soil where the seedling is located, thereby ensuring the stability of the seedling removal process from the soil.

[0017] Third, after adjusting the seedling lifting clamp to the gripping position, the four seedling lifting clamps on both sides rotate simultaneously through the reverse linkage component, and the two seedling lifting clamps on the same side rotate relative to each other, thereby clamping the seedling lifting clamp onto the outer wall of the seedling. By gripping and fixing at four points, the fixing points of the seedling are improved, thus ensuring the stability of the seedling lifting process.

[0018] Fourth, the output shaft of the motor drives the active bevel gear to rotate, causing the two driven bevel gears that mesh with the active bevel gear to rotate in opposite directions. This causes the two movable shafts to rotate in opposite directions along with the two driven bevel gears, thereby causing the two seedling grabbers on the same side to rotate relative to each other. The rotation angle of the two seedling grabbers on the same side can be adjusted according to the size of the seedling, thus making it suitable for seedlings of different sizes.

[0019] 5. During the process of adjusting the center of gravity of the seedling lifting clamp by rotating the adjusting screw and moving the displacement frame, the displacement frame slides against the outside of the guide rod. The guide rod, which is parallel to the adjusting screw, ensures the stability of the movement direction of the displacement frame and avoids positional deviation, thereby ensuring the accuracy of the adjustment of the center of gravity of the seedling lifting clamp.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The following are specific implementation cases and appendices. Figure 1-4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0027] A landscape tree lifting device includes a movable base 1. A center-of-gravity adjustment component is mounted on the top of the movable base 1 to adjust the lifting gripping position. A displacement frame 2 is mounted at the output end of the center-of-gravity adjustment component. By adjusting the longitudinal position of the displacement frame 2 using the center-of-gravity adjustment component on the movable base 1, the position of the displacement frame 2 is adjusted according to the height of the sapling, ensuring that the lifting gripper 7 is positioned at the center of gravity of the sapling. This ensures the stability of the sapling during the lifting process and provides protection. The height of the lifting gripper 7 can be adjusted according to the height of the sapling using the center-of-gravity adjustment component, making it suitable for handling saplings of different heights and thus possessing versatility.

[0028] A propulsion frame 3 is provided on the front side of the displacement frame 2, and a propulsion component for adjusting the lateral displacement of the propulsion frame 3 is provided on the displacement frame 2. Through the propulsion component located on the displacement frame 2, the seedling lifting clamps 7 move laterally, ensuring that the two seedling lifting clamps 7 move to both sides of the seedling. The position of the two seedling lifting clamps 7 is adjusted according to the position of the soil where the seedling is located, thereby ensuring the stability of the seedling removal process from the soil.

[0029] The front side of the pusher frame 3 is symmetrically fixed with brackets 11. Each bracket 11 is equipped with a seedling-lifting gripper 7 that rotates in opposite directions, and the bracket 11 is equipped with a reverse linkage component that drives the seedling-lifting gripper 7 to grab the seedling. The brackets 11 are fixed at both ends of the front side of the pusher frame 3 by connecting brackets, so that the two brackets 11 are symmetrically located on the front side of the pusher frame 3. Each bracket 11 has two seedling-lifting grippers 7 that rotate in opposite directions, and the seedling-lifting grippers 7 are arc-shaped.

[0030] After adjusting the seedling lifting clamp 7 to the gripping position, the four seedling lifting clamps 7 on both sides rotate simultaneously through the reverse linkage component, and the two seedling lifting clamps 7 on the same side rotate relative to each other, thereby clamping the seedling lifting clamp 7 onto the outer wall of the seedling. By gripping and fixing at four points, the fixing points of the seedling are improved, thus ensuring the stability of the seedling lifting process.

[0031] The reverse linkage component includes a driving bevel gear 4 rotatably mounted on a bracket 11. A motor is fixed to each bracket 11 by a cover, with the motor's output shaft and the seedling gripper 7 positioned perpendicularly. The motor is connected to an external power source via wires. The driving bevel gear 4 is fixedly fitted onto the outside of the motor's output shaft through a centrally located mounting hole. Driven bevel gears 5 are symmetrically arranged on the upper and lower sides of the outer wall of the driving bevel gear 4. The driven bevel gears 5 are located outside the movable shaft 6, which is rotatably mounted within the inner cavity of the bracket 11. The seedling gripper 7 is fitted onto the outside of the movable shaft 6.

[0032] Bearings are symmetrically embedded in the inner wall of the bracket 11 on the side of the driving bevel gear 4 away from the motor. Two movable shafts 6 are also embedded in these bearings, and are aligned vertically. A driven bevel gear 5 is sleeved on the outside of each movable shaft 6, positioned perpendicular to the driving bevel gear 4. The mating seats 10 of the seedling lifting gripper 7 are simultaneously fixed to the two movable shafts 6 on the same side, allowing the seedling lifting gripper 7 to rotate with the movable shafts 6.

[0033] When grasping saplings, the motor is connected to the power supply, causing the motor's output shaft to drive the active bevel gear 4 to rotate. This causes the two driven bevel gears 5, which mesh with the active bevel gear 4, to rotate in opposite directions. Consequently, the two movable shafts 6 rotate in opposite directions along with the two driven bevel gears 5, resulting in the two sapling grasping clamps 7 on the same side rotating relative to each other. The rotation angle of the two sapling grasping clamps 7 on the same side can be adjusted according to the size of the sapling, thus making it suitable for saplings of different sizes.

[0034] The inner wall of the seedling grabber 7 is evenly provided with protective pads 12. Multiple protective pads 12 are fixedly installed circumferentially on the inner side of each seedling grabber 7. The protective pads 12 are made of elastic material and provide protection for the gripping area of ​​the seedling.

[0035] It is worth noting that the center of gravity adjustment assembly includes an adjusting screw 8 that is longitudinally rotatably mounted on the top of the movable base 1, and a displacement frame 2 threadedly connected to the outside of the adjusting screw 8. A fixed frame 13 is vertically fixedly mounted on the top of the movable base 1. Bearings are embedded in the inner wall of the top of the fixed frame 13 and the top of the displacement frame 2, respectively. Both ends of the adjusting screw 8 are embedded inside the two bearings. The displacement frame 2 is connected to the adjusting screw 8 through a centrally located threaded through hole. A motor is fixed to the top of the fixed frame 13 by a cover, and the motor's output shaft passes through the top of the fixed frame 13 and connects to the top of the adjusting screw 8.

[0036] In addition, a directional guide rod 14 parallel to the adjusting screw 8 is fixedly installed on the top of the movable base 1, and the displacement frame 2 is sleeved on the outside of the directional guide rod 14. The top end of the directional guide rod 14 is vertically fixed to the top of the inner wall of the displacement frame 2, and the bottom end of the directional guide rod 14 is vertically fixed to the top of the movable base 1. The directional guide rod 14 is positioned parallel to the adjusting screw 8. The displacement frame 2 is movably sleeved on the outside of the directional guide rod 14 through through holes on both sides.

[0037] During the process of adjusting the center of gravity of the seedling grab 7 by rotating the adjusting screw 8 and adjusting the displacement frame 2, the displacement frame 2 slides against the outside of the guide rod 14. The guide rod 14, which is parallel to the adjusting screw 8, ensures the stability of the movement direction of the displacement frame 2 and avoids position deviation, thereby ensuring the accuracy of the adjustment of the center of gravity of the seedling grab 7.

[0038] Additionally, the propulsion assembly includes a propulsion screw 9 rotatably mounted on the rear side of the displacement frame 2. A pusher seat 17 is threadedly connected to the external side of the propulsion screw 9. The pusher seat 17 is connected to the propulsion frame 3 via a connecting rod 16, which penetrates the inner cavity of the displacement frame 2. An outer frame 15 is vertically fixedly mounted on the rear side of the displacement frame 2. Bearings are embedded in the opposing surfaces of the outer frame 15 and the displacement frame 2, and both ends of the propulsion screw 9 are respectively embedded inside the two bearings. The pusher seat 17 is connected to the propulsion screw 9 through a threaded through-hole penetrating the inner cavity. A motor is fixed to the outer wall of the outer frame 15 by a cover. The motor's output shaft penetrates the inner cavity of the outer frame 15 and is fixedly connected to one end of the propulsion screw 9. The motor is connected to an external power source via wires.

[0039] The two ends of the connecting rod 16 are fixed vertically to the opposite surfaces of the outer frame 15 and the displacement frame 2, and the connecting rod 16 is positioned parallel to the push screw 9.

[0040] During the process of adjusting the lateral position of the seedling grabber 7, the output shaft of the motor drives the push screw 9 to rotate, which causes the push seat 17, which is threadedly connected to the push screw 9, to move the push frame 3 through the connecting rod 16. This causes the push frame 3 to move the seedling grabber 7 toward the seedling, thus ensuring the accuracy of the seedling grabbing position adjustment.

[0041] Furthermore, the positions of the directional guide rod 14 and the connecting rod 16 are staggered to avoid interference during the adjustment of the seedling clamp 7.

[0042] This embodiment describes a seedling lifting device for landscape trees. The working principle is as follows: First, the lifting clamp 7 is moved to the position of the seedling to be operated by the moving seat 1. Then, the output shaft of the motor drives the adjusting screw 8 to rotate, so that the displacement frame 2 drives the lifting clamp 7 to adjust to the center of gravity of the seedling.

[0043] Then, the output shaft of the motor drives the push screw 9 to rotate, so that the push seat 17, which is threadedly connected to the push screw 9, drives the push frame 3 to move through the connecting rod 16, so that the push frame 3 drives the seedling grabbers 7 to move towards the seedling, and moves the four seedling grabbers 7 to both sides of the seedling respectively.

[0044] Then the motor is connected to the power supply, so that the output shaft of the motor drives the active bevel gear 4 to rotate, so that the two driven bevel gears 5 that mesh with the active bevel gear 4 rotate in the opposite direction, so that the two movable shafts 6 rotate in the opposite direction with the two driven bevel gears 5 respectively, so that the two seedling grabbing clips 7 on the same side rotate relative to each other, so that the four seedling grabbing clips 7 are simultaneously engaged on the outer wall of the seedling.

[0045] Then, the seedling is removed from the soil by driving the adjusting screw 8.
