[0025] Example 1

[0026] See attached Figure 1-5The present application provides a greening tree transplanting device, including a hoisting device 1 and a clamping device 2, wherein the hoisting device 1 is installed on a base plate 3, the hoisting device 1 includes a support plate 4, the support plate 4 is provided with a crossbeam 5, the support plate 4 is rotatably connected with a first fixed pulley 6, a second fixed pulley 7, a third fixed pulley 8 and a fourth fixed pulley 9, the base plate 3 is rotatably connected with a first rope winding wheel 10, the first rope winding wheel 10 is provided with a first traction rope 11, the first traction rope 11 passes through the first fixed pulley 6, the second fixed pulley 7 and the third fixed pulley 8 and is fixed on a hoop 12, the hoisting device 1 is used to hoist and lower the tree to be transplanted, the clamping device 2 is fixed on the base plate 3, and the clamping device 2 is used to clamp the tree to be transplanted The clamping device 2 includes a clamping base plate 13, and the clamping base plate 13 is rotatably connected with a screw rod 14, and the screw rod 14 includes a left-handed thread and a right-handed thread. The screw rod 14 is provided with a first nut 15 and a second nut 16 that match, and the first nut 15 and the second nut 16 respectively match with the left-handed thread and the right-handed thread, so that when the screw rod 14 is rotated, the first nut 15 and the second nut 16 move in opposite directions to achieve the clamping and loosening functions. The first nut 15 and the second nut 16 are respectively provided with two clamping wheels 17, and the clamping wheels 17 are rotatably connected to the clamping wheel mounting plate 18, and the clamping wheel mounting plate 18 is respectively fixed to the first nut 15 and the second nut 16. When the clamping wheel 17 is clamped on the tree After the trunk is connected, when the tree is pulled upward, the clamping wheel 17 rotates along the trunk to reduce friction. The clamping base plate 13 is provided with a brake block 19, and the brake block 19 passes through the clamping wheel mounting plate 18 and the clamping base plate 13 and is movably connected to the clamping base plate 13. The brake block 19 is sleeved with a spring 20, one end of the spring 20 is connected to the clamping base plate 13, and the other end is connected to the brake block 19. In the initial state, the brake block 19 supports the clamping wheel 17 under the elastic force of the spring 20 for braking. The brake block 19 is provided with a second traction rope 21, one end of the second traction rope 21 is fixedly connected to the brake block 19, and the other end passes around the fourth fixed pulley 9 and is fixedly connected to the second winding rope The second rope-winding wheel 22 is rotatably connected to the support plate 4, and the second traction rope 21 is retracted and released by rotating the second rope-winding wheel 22, so as to realize the braking and releasing of the clamping wheel 17. When in use, the clamping device 2 is aimed at the tree trunk to be transplanted, and the screw rod 14 is rotated to clamp the clamping wheels 17 on both sides against the tree trunk, and the hoop 12 is put on the tree trunk and locked, and the first rope-winding wheel 10 is rotated to rewind the first traction rope 11. At the same time, the second rope-winding wheel 22 is rotated to rewind the second traction rope 21 to pull out the brake block 19 from the clamping wheel 17, so that the clamping wheel 17 can rotate, and the tree to be transplanted is pulled up by rewinding the first traction rope 11, and transferred to the place to be transplanted for planting.The tree trunk is clamped by the clamping wheel 17 to prevent the tree from rotating and shaking during hoisting. The relative rotation between the clamping wheel 17 and the tree trunk reduces friction. When the first traction rope 11 breaks, the second rope reel 22 is released so that the brake block 19 rebounds under the elastic force of the spring 20 to brake the clamping wheel 17, preventing the tree from sliding down and causing loss of life and property.

[0027] Specifically, the base plate 3 is provided with a first motor 23, and the output end of the first motor 23 is connected to the first rope winding wheel 10. The first motor 23 provides power to free up labor and improve efficiency.

[0028] Specifically, the clamping base plate 13 is provided with a second motor 24 , and the output end of the second motor 24 is connected to the screw rod 14 . The second motor 24 provides power to drive the screw rod 14 to rotate, thereby improving efficiency.

[0029] Specifically, the clamping wheel 17 is provided with a plurality of protrusions 25. The protrusions 25 are provided to increase the contact friction between the clamping wheel 17 and the tree trunk, thereby preventing the tree from rotating during clamping.

[0030] Specifically, the hoop 12 includes a left half arc block 26 and a right half arc block 27, and the left half arc block 26 and the right half arc block 27 are connected by a bolt 28, so that the hoop 12 is divided into the left half arc block 26 and the right half arc block 27, and then connected by the bolt 28, so as to realize the adjustable function of the hoop 12, which can make the clamping tighter and can also adapt to tree trunks of different sizes.

[0031] Specifically, the second fixed pulley 7 is provided with a first magnet 29, and the second rope pulley 22 is provided with a second magnet 30. The first magnet 29 and the second magnet 30 cooperate with each other through magnetic force. The first magnet 29 is fixedly connected to the second fixed pulley 7, and the second magnet 30 is fixedly connected to the second rope pulley 22. The first magnet 29 and the second magnet 30 are coaxial, and there is a gap between them. When working, the second fixed pulley 7 rotates under the friction force of the first traction rope 11 and the second fixed pulley 7, thereby driving the first magnet 29 to rotate. Because the first magnet 29 and the second magnet 30 are connected through magnetic force, the rotation of the first magnet 29 drives the second magnet 30 to rotate, thereby driving the second rope pulley 2 2 rotates, the second rope wheel 22 rotates to reel in and release the second traction rope 21, so as to realize the function of pulling out the brake block 19. When the first magnet 29 and the second magnet 30 cooperate with the magnetic force and the elastic force of the spring 20 to reach a balance, the second rope wheel 22 will keep the pulling force on the second traction rope 21 stable, maintain the pulled-out state of the brake block 19, so that the clamping wheel 17 can rotate. When the first traction rope 11 suddenly breaks, the second fixed pulley 7 loses the friction force, so that the second rope wheel 22 also loses the force transmitted by the second fixed pulley 7. At this time, the brake block 19 is quickly reset and braked under the elastic force of the spring 20, so as to achieve the effect of rapid braking, thereby preventing the tree from sliding down and causing loss of life and property.

[0032] Example 2

[0033] See attached Figure 1-5 The difference between this embodiment and embodiment 1 is that a cart 31 is provided under the base plate 3, and the base plate 3 is installed on the cart 31. The cart 31 is used to conveniently transfer the tree to the place to be planted for planting, thereby saving physical strength of personnel and improving efficiency.

[0034] Specifically, the cart 31 is provided with a turntable 32, and the turntable 32 is rotatably connected to the cart 31. The base plate 3 is movably connected to the turntable 32, and the tree to be transplanted is rotated to the top of the pit through the turntable 32. The turntable 32 is provided with a hydraulic cylinder 33, and the output end of the hydraulic cylinder 33 is connected to the base plate 3. The turntable 32 is used to conveniently rotate the tree to be transplanted to the top of the pit. The hydraulic cylinder 33 is provided to make up for the distance that the tree cannot reach the pit. The rotation of the turntable 32 and the extension and retraction of the hydraulic cylinder 33 can realize a better transfer of the tree to the top of the pit, avoiding the phenomenon of manual lifting due to the inability to reach the pit, thereby improving the planting efficiency.
