DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a seedling lifting device for seedling transplanting, including a base 1, the base 1 is C-shaped, a lifting frame 3 is slidable up and down in the base 1, the lifting frame 3 is C-shaped, support frames 4 are hinged on both sides of the inner wall of the lifting frame 3, and a telescopic shovel mechanism is arranged inside the support frame 4.

[0021] Vertical grooves are provided on the inner sides of the two support frames 4. The telescopic shovel mechanism includes a shovel head 5, a movable block 6, a fixed block 7, and a first hydraulic cylinder 8. Arc grooves are provided on both sides of the vertical grooves. The movable block 6 can be slidably arranged in the arc grooves. The outer side of the shovel head 5 is fixedly connected to the movable block 6. The first hydraulic cylinder 8 is hinged at the upper end of the vertical groove. The lower end of the first hydraulic cylinder 8 is hinged to the upper end of the outer side of the shovel head 5. When the first hydraulic cylinder 8 is extended, the movable block 6 slides along the arc groove. Second hydraulic cylinders 9 are hinged at both ends of the upper surface of the lifting frame 3. The upper end of the second hydraulic cylinder 9 is hinged to the top of the outer side wall of the support frame 4. When the second hydraulic cylinder 9 is extended, the upper ends of the two shovel heads 5 tilt inward.

[0022] The shovel head 5 is arc-shaped as a whole, and the bottom end is inclined inward to form an arc surface, that is, a spherical structure is formed. The bottom end of the arc groove is also inclined inward. When the first hydraulic cylinder 8 is extended, the movable block 6 moves downward, driving the shovel head 5 to move downward. Since the movable block 6 slides along the arc groove, the movement trajectory of the movable block 6 during the downward movement is an arc that is gradually inclined inward, thereby driving the shovel head 5 to gradually tilt during the downward digging process, thereby digging an arc that is inclined inward from top to bottom on the soil, directly reaching the bottom of the root system.

[0023] A groove is formed on the back of the shovel head 5, and a fixed block 7 is arranged in the support frame 4. The fixed block 7 is embedded in the groove. The cross-sections of the groove and the fixed block 7 are both dovetail-shaped, so that when the shovel head 5 is digging, the fixed block 7 can support and limit the shovel head 5 to prevent the shovel head 5 from tilting due to force.

[0024] Both ends of the first hydraulic cylinder 8 are hinged, so that when the movable block 6 changes its angle during the sliding process, the tilt angle of the first hydraulic cylinder 8 can change accordingly without causing interference.

[0025] The seedlings are inserted from the open side of the base 1 and the lifting frame 3 into the middle position of the lifting frame 3, and the two shovel heads 5 are basically symmetrical on both sides of the seedlings and then dig down. After one digging, the shovel heads 5 are reset up and down, and the device can be rotated around the seedlings at a certain angle, so that the two shovel heads 5 move to the un-dug position, and dig down again. After repeating several times, a relatively uniform soil ball separated from the soil can be dug out near the root system.

[0026] A plurality of support frames 4 may be arranged on the lifting frame 3, and a group of telescopic shovel mechanisms are arranged in each support frame 4, so that the plurality of telescopic shovel mechanisms form an approximately semi-circular structure, so that an independent soil ball can be formed by digging only twice.

[0027] The inclination angle of the support frame 4 in the initial state can be changed according to the required size of the soil ball. For example, when a larger soil ball is required, the second hydraulic cylinder 9 is first extended a certain distance so that the top of the support frame 4 is tilted inward at a certain angle, thereby increasing the distance between the bottom ends of the two shovel heads 5, and then digging down can dig out a larger soil ball. When the seedlings themselves are required to be smaller and the soil ball is required to be smaller, the second hydraulic cylinder 9 can first be contracted to a certain length so that the top of the support frame 4 is tilted outward at a certain angle, thereby reducing the distance between the bottom ends of the two shovel heads 5, thereby digging out a smaller soil ball. The second hydraulic cylinder 9 can have multiple strokes.

[0028] After the shovel head 5 is dug down to the right position, it is kept still first. At this time, the shovel head 5 is above the hinge of the support frame 4 and the lifting frame 3. Then the second hydraulic cylinder 9 is extended, so that the top of the support frame 4 tilts inward. At this time, the top of the shovel head 5 will tilt inward at a certain angle, thereby squeezing the upper part of the soil ball and compacting the soil. Then the second hydraulic cylinder 9 can be retracted again, so that the bottom end of the shovel head 5 tilts upward obliquely, thereby compacting the lower part of the soil ball. Repeat one or two times to compact the soil inside the shovel head 5. Perform the above operation after each digging to compact the soil ball, prevent the soil ball from scattering after lifting the seedlings, and keep the soil ball tight and complete. The extension and contraction of the second hydraulic cylinder 9 can be controlled according to the height and position of the shovel head 5, so that the shovel head 5 tilts in the appropriate direction to compact the soil ball.

[0029] Furthermore, movable frames 2 are vertically fixedly connected to both ends of the base 1, connecting blocks are fixedly connected to the inner upper ends of the two movable frames 2, and a third hydraulic cylinder 10 is vertically fixedly connected to the lower surface of the connecting block, and the lower ends of multiple third hydraulic cylinders 10 are fixedly connected to the lifting frame 3. When the multiple third hydraulic cylinders 10 are retracted, the lifting frame 3 rises.

[0030] In this embodiment, when the third hydraulic cylinder 10 is extended, it will drive the lifting frame 3 to move downward to the lowest point, so that the bottom of the shovel head 5 is closest to the soil, and then digging begins. After the last excavation and tightening of the soil, the shovel head 5 may not be reset upward, but may remain in the position of clamping the soil ball. The third hydraulic cylinder 10 will contract, driving the lifting frame 3 to rise as a whole, thereby driving the shovel head 5 to clamp the soil ball and rise, lifting the seedlings together with the soil ball, moving them aside and putting them down, and completing the seedling removal.

[0031] Furthermore, two first support rods 11 spaced apart from each other are vertically fixedly connected on the upper surface of the base 1 and located behind the shovel head 5, a movable rod 13 is rotatably arranged between the first support rods 11, a clamp is arranged at one end of the movable rod 13, and a fourth hydraulic cylinder 14 for driving the clamp to open or tighten is arranged inside the movable rod 13.

[0032] Furthermore, a second support rod 12 is rotatably arranged between the first support rod 11, a fixing groove is provided at the other end of the second support rod 12, first fixing holes are provided on both sides of the fixing groove, a connecting seat is fixedly connected to the bottom of the surface of the movable rod 13, a second fixing hole is provided on the connecting seat, and the first fixing hole is fixed by a pin when corresponding to the second fixing hole.

[0033] In this embodiment, when the clamp is in a suitable position, the seedlings can be clamped to prevent them from tipping over during the process of lifting the seedlings upwards. When clamping, a soft pad can be provided in the clamp to prevent damage to the seedlings.

[0034] When in use, the movable rod 13 and the clamp should be in a basically horizontal state. At this time, in order to fix the position of the movable rod 13, the second support rod 12 is rotated to a suitable inclination angle, so that the fixing groove on the second support rod 12 is nested outside the connecting seat, and the first fixing hole is opposite to the second fixing hole and fixed by a bayonet. At this time, the first support rod 11, the second support rod 12 and the movable rod 13 form a triangular structure, which supports the movable rod 13 so that it is in a suitable position, which is convenient for supporting the clamp to clamp the seedlings. The clamp can be a hydraulic clamp, which is driven by the fourth hydraulic cylinder 14 to clamp and release.

[0035] When not in use, the movable rod 13 and the second support rod 12 are disconnected and made to hang naturally, which reduces the occupied space, facilitates the device to adjust the position, and avoids damaging the trees. The second support rod 12 can rotate from both inside and outside without being affected by the seedlings inside the lifting frame 3.

[0036] Furthermore, the upper surface of the base 1 is fixedly connected to a connecting seat mechanism, and the connecting seat mechanism includes a fixing seat 16 and a reinforcing rod 17. There are two fixing seats 16 that are spaced apart from each other, and mounting holes are provided on the fixing seats 16. The two fixing seats 16 are fixedly connected to the upper surface of the base 1, and there are two reinforcing rods 17 that are respectively fixedly connected between the fixing seats 16 and the base 1.

[0037] In this embodiment, the device can be installed on power mechanical equipment such as tractors and small loaders. On the one hand, it is used to carry the mobile device, and on the other hand, it can provide power and oil to the hydraulic equipment in the device to enable the device to work normally. At the same time, the device can be supported and fixed to prevent the device from being pushed upward by the reaction force when digging downwards.

[0038] The fixing seat 16 is provided with a mounting hole for mounting on mechanical equipment, and two reinforcing rods 17 strengthen the connection between the fixing seat 16 and the base 1 .

[0039] Furthermore, a plurality of supporting legs 15 are fixedly connected to the lower surface of the base 1 , and the number of supporting legs 15 is no less than four.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
