Description

Technical Field

[0001] The present invention relates to the technical field of garden planting, and particularly to an auxiliary planting device for municipal gardens. Background Art

[0002] In order to reduce the content of harmful gases and particulate matter in the urban air and improve air quality, currently, the method of increasing the area of municipal garden greening is usually adopted. The methods of municipal garden greening include planting grass, trees, cultivating flower beds, etc. Among them, when planting trees, transplantation is mostly used. Specifically, the cultivated saplings are transplanted from the nurseries where saplings are professionally cultivated to the gardens that need greening. During transplantation, in order to ensure the survival rate of the saplings, usually a part of the soil is retained at the roots when transplanting the saplings. Mostly, when digging out the saplings, the soil around their roots is dug out together, so that the dug-out soil is hemispherical. And in order to maintain the structure of the soil ball and the water in it, a protective film is usually wound around the outside of the soil ball.

[0003] After the saplings are transported to the location to be planted, usually, a pit for transplanting the saplings needs to be dug first, and then the saplings are put into the pit and the soil is backfilled. However, the sizes of the dug pits are not the same, and the sizes of the soil balls at the roots of the saplings are also not the same. It is impossible to ensure that the pits can adapt to the soil balls at the roots of different saplings. If the pit is too small, it needs to be enlarged again. If the pit is too large, more time is required when backfilling the soil, which increases the extra workload and seriously reduces the work efficiency. Summary of the Invention

Detailed implementation manners

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1: An auxiliary planting device for municipal gardens, as Figures 1 - 3As shown in the figure, it includes a transport vehicle 1. A support frame 2 is fixedly connected to the front of the transport vehicle 1. An electric rotating shaft 3 is installed on the support frame 2. A first fixing frame 4 is fixedly connected to the left side of the electric rotating shaft 3. A first electric push rod 5 is installed on the first fixing frame 4. The telescopic end of the first electric push rod 5 is fixedly connected to a fixing ring 6. A circular cavity is arranged on the lower side of the fixing ring 6. A rotating ring 7 is hermetically and rotatably connected in the circular cavity of the fixing ring 6. The circular cavity of the fixing ring 6 is filled with hydraulic oil. A guiding frame 8 is fixedly connected to the lower side of the rotating ring 7. The guiding frame 8 is filled with hydraulic oil. A hose fixedly connected and communicated with the guiding frame 8 is fixedly connected to the rotating ring 7. The hose of the rotating ring 7 is communicated with the circular cavity of the fixing ring 6. The hose is filled with hydraulic oil. A motor 9 is installed on the upper side of the fixing ring 6 through a mounting frame. The output shaft of the motor 9 is fixedly connected to the guiding frame 8. The guiding frame 8 is driven by the output shaft of the motor 9 to rotate circumferentially. Two sliding members 10 evenly distributed circumferentially are hermetically and slidably connected to the guiding frame 8. Springs are fixedly connected between the sliding members 10 and the guiding frame 8. Soil cleaning members 11 are installed on the sliding members 10. The two soil cleaning members 11 cooperate with each other to dig out a soil pit in a revolving manner. By changing the amount of hydraulic oil in the guiding frame 8, the distance between the two sliding members 10 is controlled, and then the distance between the two soil cleaning members 11 is controlled to adjust the size of the dug soil pit. A diameter detection component for detecting the diameter of the soil ball at the root of the tree is arranged on the support frame 2. A fixing component for clamping and carrying the tree is arranged on the electric rotating shaft 3.

[0035] As Figure 1 , Figure 2 and Figures 4 - 8As shown in the figure, the diameter detection component includes a second fixing frame 13, which is fixedly connected to the lower part of the front side of the support frame 2. A second electric push rod 14 is installed on the front side of the second fixing frame 13. The telescopic end of the second electric push rod 14 is fixedly connected to a first fixing shell 15. A first sliding rod 16 is slidably connected in the first fixing shell 15. A spring is fixedly connected between the first sliding rod 16 and the first fixing shell 15. A support platform 17 is fixedly connected to the upper side of the first sliding rod 16. By the contraction of the spring of the first sliding rod 16, it is prevented that the subsequent upward movement of the support platform 17 damages the structure of the soil ball. The telescopic end of the second electric push rod 14 is fixedly connected to a third fixing frame 18. Four support rods 19 evenly distributed in the circumferential direction are slidably connected to the third fixing frame 18. Four first arc-shaped plates 20 evenly distributed in the circumferential direction are hinged to the support platform 17. The first arc-shaped plate 20 is hinged to the adjacent support rod 19. By the upward movement of the third fixing frame 18, the sliding of the support rod 19 and the stillness of the support platform 17, while pushing the first arc-shaped plate 20 upward, the first arc-shaped plate 20 rotates, so that the four first arc-shaped plates 20 form a hemispherical shape and actively fit the outer surface of the soil ball. Two arc-shaped shells 21 evenly distributed at equal intervals are fixedly connected to the back side of each of the four first arc-shaped plates 20. A second fixing shell 22 evenly distributed at equal intervals is communicated with one side of the arc-shaped shell 21 facing the support platform 17. Hydraulic oil is filled in both the arc-shaped shell 21 and the second fixing shell 22. The second fixing shell 22 penetrates through the adjacent first arc-shaped plate 20. A second sliding rod 23 is slidably connected to the second fixing shell 22. The second sliding rod 23 fits the soil ball to change the relative position between the second sliding rod 23 and the adjacent second fixing shell 22, and further adjusts the amount of hydraulic oil in the second fixing shell 22. All eight arc-shaped shells 21 are communicated with the annular cavity of the fixing ring 6 through hoses. Through the flow of the hydraulic oil in all the second fixing shells 22, the amount of hydraulic oil flowing into the annular cavity of the fixing ring 6 is adjusted according to the size of the soil ball, so as to change the distance between the two soil cleaning components 11, that is, the diameter of the soil ball is proportional to the amount of hydraulic oil flowing into the annular cavity of the fixing ring 6.

[0036] As Figure 1 , Figure 2 and Figure 4 shown in the figure, the fixing component includes an electric slide rail 24, which is arranged on the front side of the electric rotating shaft 3. A fourth fixing frame 25 is slidably connected in the electric slide rail 24. The fourth fixing frame 25 is located above the second fixing frame 13. Two second arc-shaped plates 26 symmetrically distributed left and right are hinged to the front side of the fourth fixing frame 25. A locking member 27 (the locking member 27 is an existing locking method and will not be described in detail here) is jointly arranged on the front sides of the two second arc-shaped plates 26. Two telescopic rods 28 evenly distributed at equal intervals are fixedly connected to the inner sides of the two second arc-shaped plates 26. The telescopic end of the telescopic rod 28 is fixedly connected to an elastic block 29. A spring is fixedly connected between the elastic block 29 and the adjacent second arc-shaped plate 26. The elastic block 29 is used to contact the tree trunk. By using the elasticity of the elastic block 29 and the expansion and contraction of the adjacent spring, the shape of the tree trunk is adapted to fix the tree trunk.

[0037] When the device is needed to assist in planting saplings, the user unlocks the locking member 27 and rotates the two second arc-shaped plates 26 to separate. Then, the soil ball at the root of the sapling is placed on the support platform 17. The two second arc-shaped plates 26 are rotated back to their original positions, and the locking member 27 is locked again to keep the two second arc-shaped plates 26 relatively stable. During the process of rotating the two second arc-shaped plates 26 back to their original positions, the four elastic blocks 29 gradually come into contact with the sapling and are limited by the sapling, respectively squeezing the telescopic parts of the adjacent telescopic rods 28. During the movement of the elastic blocks 29, the springs of the elastic blocks 29 are compressed, and the elastic blocks 29 change their own shapes according to the shape of the sapling to ensure the stability of the sapling.

[0038] When the fixing of the sapling is completed, the user starts the transport vehicle 1 and the second electric push rod 14. The sapling is transported to the planting position by the transport vehicle 1, and the two soil cleaning members 11 are positioned directly above the planting position. Then, the transport vehicle 1 is stopped. During this process, the telescopic end of the second electric push rod 14 moves upward, driving the first fixed shell 15 and the third fixing frame 18 to move upward together. During the upward movement of the first fixed shell 15, the first fixed shell 15 gradually compresses the spring of the first sliding rod 16, making the positions of the first sliding rod 16 and the support platform 17 stable. When the third fixing frame 18 moves upward, it drives the four support rods 19 evenly distributed circumferentially to move upward. During the upward movement of the support rods 19, the support rods 19 slide along the third fixing frame 18 towards the direction close to the first fixed shell 15, and a rotation occurs between the support rods 19 and the adjacent first arc-shaped plates 20, and a rotation occurs between the first arc-shaped plates 20 and the support platform 17, causing the four first arc-shaped plates 20 to gather together. The first arc-shaped plates 20 drive the parts thereon to approach the soil ball until the telescopic end of the second electric push rod 14 extends, and then the second electric push rod 14 is turned off.

[0039] During the process of the first arc-shaped plate 20 approaching the soil ball, the second sliding rod 23 contacts the soil ball and is blocked by the soil ball, causing the second sliding rod 23 to slide into the adjacent second fixed shell 22. The second sliding rod 23 pushes the hydraulic oil in the adjacent second fixed shell 22 into the adjacent arc-shaped shell 21 and is introduced into the annular cavity of the fixing ring 6 through the adjacent hose. Then, the hydraulic oil enters the guiding frame 8 through the hose on the swivel ring 7, pushing the two sliding members 10 outwards, causing the sliding members 10 to compress the adjacent springs. The sliding members 10 drive the adjacent soil cleaning members 11 to move, so as to change the subsequent digging size. Through the contact of all the second sliding rods 23 with the soil ball, the distance between the two soil cleaning members 11 is changed according to the size of the soil ball, that is, the digging size is changed according to the size of the soil ball, avoiding the extra workload caused by the inappropriate digging size and improving the work efficiency.

[0040] When the transport vehicle 1 transports the sapling to the designated position and stops and the two soil cleaning pieces 11 complete the distance change, the user starts the first electric push rod 5, the motor 9 and the two soil cleaning pieces 11, so that the telescopic end of the first electric push rod 5 moves slowly downward, and drives the parts on the fixed ring 6 to move downward. While the fixed ring 6 moves downward, the motor 9 drives the parts on the guide frame 8 to make a circular motion, so that the two soil cleaning pieces 11 on the guide frame 8 clear the soil at the position to be planted until the soil cleaning pieces 11 clear the soil of the specified depth at the position to be planted. The motor 9 and the two soil cleaning pieces 11 are turned off, and the telescopic end of the first electric push rod 5 is controlled to be retracted. The retraction of the first electric push rod 5 drives the parts on the fixed ring 6 to return to the initial position, and a soil pit of the size corresponding to the sapling to be planted is dug at the position to be planted.

[0041] After a pit of a size corresponding to the size of the sapling to be planted is dug at the location to be planted, the user starts the second electric push rod 14, so that the telescopic end of the second electric push rod 14 is retracted downward, and the first fixed shell 15 and the third fixed frame 18 are driven to move downward together. During this process, the spring force of the first sliding rod 16 squeezed by the first fixed shell 15 is gradually released, and at the same time, the third fixed frame 18 drives four circumferentially evenly distributed support rods 19 to move downward. During the downward movement of the support rod 19, the support rod 19 slides along the third fixed frame 18 in a direction away from the first fixed shell 15, and a gap is generated between the support rod 19 and the adjacent first curved plate 20. The first electric push rod 14 is retracted and the second electric push rod 14 is closed. After the first electric push rod 14 is retracted, the soil ball releases the obstruction of the second sliding rod 23, and the thrust of the second sliding rod 23 on the hydraulic oil disappears. The thrust of the hydraulic oil on the two sliding members 10 disappears, and the spring force adjacent to the sliding member 10 is gradually released, causing the sliding member 10 to retract inward, driving the adjacent soil cleaning member 11 to return to its initial position. At the same time, the two sliding members 10 push the hydraulic oil to flow back through the hose, pushing all the second sliding rods 23 back to their initial state.

[0042] After the first electric push rod 5 and the second electric push rod 14 are reset to the initial state, the user starts the electric slide rail 24. The electric slide rail 24 drives the fourth fixing frame 25 and the parts and saplings thereon to move upward together until the sapling breaks away from the limit of the second fixing frame 13. Then the user stops the electric slide rail 24 and starts the electric rotating shaft 3. The electric rotating shaft 3 rotates to drive the first fixing frame 4 and the fourth fixing frame 25 and the parts and saplings thereon to rotate together until the sapling is directly above the pit to be planted. Subsequently, the user stops the electric rotating shaft 3 and starts the electric slide rail 24. The electric slide rail 24 drives the fourth fixing frame 25 and the sapling fixed by the fourth fixing frame 25 to move downward together until the soil ball at the root of the sapling is placed into the pit to be planted. Then the user stops the electric slide rail 24 and unlocks the locking member 27 to release the fixation of the sapling. After the fixation of the sapling is released, the user separates the protective film of the soil ball at the root of the sapling and then backfills the soil to complete the planting of the sapling. After the planting is completed, the user starts the transport vehicle 1 to transport and plant the next sapling, and so on in a cycle.

[0043] Embodiment 2: On the basis of Embodiment 1, as Figure 2 , Figure 4 , Figure 9 , Figure 10 , Figure 12 and Figure 13As shown, it further includes a separation component which is arranged on the first fixed shell 15 and is used to separate the protective film from the soil ball. The separation component includes four arc-shaped frames 30 that are circumferentially and evenly distributed. The four arc-shaped frames 30 are all fixedly connected to the middle of the outer peripheral side of the first fixed shell 15. The four arc-shaped frames 30 and the four first arc-shaped plates 20 are staggeredly distributed, so that the four arc-shaped frames 30 correspond to the gaps between the four first arc-shaped plates 20 after the four first arc-shaped plates 20 are attached to the soil ball. A rotating frame 31 is rotatably connected to the upper side of the arc-shaped frame 30. Third fixed shells 32 are slidably connected to the opposite sides of the four arc-shaped frames 30 and the four rotating frames 31 at equal intervals. By the contraction of the third fixed shells 32 in the arc-shaped frames 30 and the rotating frames 31, it can adapt to the diameters of different soil balls. Springs are fixedly connected between the arc-shaped frames 30 and the rotating frames 31 and the adjacent third fixed shells 32 respectively, and these springs are used to reset the third fixed shells 32. A diversion shell 33 is hermetically slidably connected in the third fixed shell 32. The diversion shell 33 is located on the side close to the sapling in the third fixed shell 32. A spring is fixedly connected between the diversion shell 33 and the adjacent third fixed shell 32, and this spring is used to reset the adjacent diversion shells 33. The diversion shell 33 is fixedly connected and communicated with a third sliding rod 34. The diversion shell 33 and the adjacent third sliding rod 34 form a transmission path for hydraulic oil and are filled with hydraulic oil. On the side of the diversion shell 33 close to the adjacent third sliding rod 34, diversion holes that are circumferentially and evenly distributed and are all communicated with its own cavity are provided. The third sliding rod 34 is hermetically slidably connected to the adjacent third fixed shell 32, so that the hydraulic oil entering the adjacent third fixed shell 32 through the diversion shell 33 pushes the adjacent diversion shell 33 and the adjacent third sliding rod 34 to move away from the sapling. The side of the third sliding rod 34 away from the adjacent third fixed shell 32 is communicated with a fourth fixed shell 35, and the fourth fixed shell 35 is filled with hydraulic oil.

[0044] As Figures 9 - 13As shown in the figure, a third electric push rod 36 and a fifth fixed shell 37 are installed on each of the four arc-shaped frames 30. The third electric push rod 36 is located below the adjacent fifth fixed shell 37. A fourth sliding rod 38 is hermetically and slidably connected in the fifth fixed shell 37. The fourth sliding rod 38 is fixedly connected to the telescopic end of the adjacent third electric push rod 36. A sliding plate 39 is hermetically and slidably connected in the fifth fixed shell 37, and a spring is fixedly connected between the two. The sliding plate 39 is located on the lower side inside the adjacent fifth fixed shell 37, and hydraulic oil is injected between the sliding plate 39 and the adjacent fifth fixed shell 37. The sliding plate 39 is hermetically and slidably connected to the adjacent fourth sliding rod 38, so that the fourth sliding rod 38 will not drive the sliding plate 39 to move upward when moving upward. The sliding plate 39 is in limit fit with the telescopic end of the adjacent third electric push rod 36. When the telescopic end of the third electric push rod 36 contacts the adjacent sliding plate 39, it pushes the adjacent sliding plate 39 to move upward. A gear is installed at the rotation center of the rotating frame 31, and a rack is installed on the upper side of the fourth sliding rod 38. The gear meshes with the rack, so that the rack of the fourth sliding rod 38 drives the adjacent rotating frame 31 to rotate through the gear of the adjacent rotating frame 31. A torsion spring is fixedly connected between the opposite side of the rotating shaft of the rotating frame 31 where the gear is installed and the adjacent arc-shaped frame 30. The torsion spring is initially in a state of storing energy. The fifth fixed shell 37 is communicated with an oil pipe 40, and hydraulic oil is injected into the oil pipe 40. The fourth fixed shell 35 is communicated with the adjacent oil pipe 40. The hydraulic oil in the fifth fixed shell 37 is transmitted to the adjacent fourth fixed shell 35 through the adjacent oil pipe 40. A sliding block 41 is slidably connected to one side of the fourth fixed shell 35 close to the adjacent oil pipe 40. An elastic oil bag 42 is fixedly connected to the side of the fourth fixed shell 35 far from the adjacent oil pipe 40. An arc-shaped rod 43 is slidably connected to the side of the fourth fixed shell 35 far from the adjacent sliding block 41. The elastic oil bag 42 is located between the adjacent sliding block 41 and the arc-shaped rod 43. The elastic oil bag 42 is fixedly connected to the adjacent arc-shaped rod 43. The elastic oil bag 42 opens downward and limits the maximum moving position of the adjacent sliding block 41. The elastic coefficient of the elastic oil bag 42 is smaller than the elastic coefficient of the spring between the diversion shell 33 and the adjacent third fixed shell 32. When the sliding block 41 moves upward, the hydraulic oil in the adjacent fourth fixed shell 35 is first pushed into the adjacent elastic oil bag 42, causing the elastic oil bag 42 to expand. The expansion of the elastic oil bag 42 pushes the adjacent arc-shaped rod 43 out so that the arc-shaped rod 43 penetrates and hooks the protective film. The elastic coefficient of the spring of the sliding plate 39 is greater than the elastic coefficient of the spring between the diversion shell 33 and the adjacent third fixed shell 32. The elastic coefficient of the spring outside the third fixed shell 32 is smaller than the elastic coefficient of the spring between the diversion shell 33 and the adjacent third fixed shell 32, so that the spring outside the third fixed shell 32 is compressed before the spring between the diversion shell 33 and the adjacent third fixed shell 32. During the process of the spring between the diversion shell 33 and the adjacent third fixed shell 32 being compressed, the spring outside the third fixed shell 32 gradually elongates and resets to ensure that the diversion shell 33 can slide smoothly in the adjacent third fixed shell 32 to hook the protective film.

[0045] AsFigure 10 , Figure 12 and Figure 14 As shown in Figure 10 , Figure 12 and Figure 14 , first T-shaped sliding rails 44 are arranged on the opposite sides of the circumferentially uniformly distributed arc-shaped frames 30, and second T-shaped sliding rails 45 are arranged on the opposite sides of the circumferentially uniformly distributed rotating frames 31. The first T-shaped sliding rail 44 and the adjacent second T-shaped sliding rail 45 form a continuous track after the adjacent rotating frame 31 rotates to a specified angle. A T-shaped slider 46 that is slidably engaged with the adjacent first T-shaped sliding rail 44 is slidably connected in the second T-shaped sliding rail 45. The T-shaped slider 46 is initially located at the uppermost side of the adjacent second T-shaped sliding rail 45. An electric wheel 47 is installed on one side of the arc-shaped frame 30 close to the first fixed shell 15. The electric wheel 47 has a driving force that can rotate in both directions. The electric wheel 47 is fixedly connected to both sides of the adjacent T-shaped slider 46 through two pull ropes respectively, for controlling the sliding of the T-shaped slider 46 in the combined T-shaped sliding rail. A fourth electric push rod 48 is fixedly connected to the T-shaped slider 46. The telescopic end of the fourth electric push rod 48 is fixedly connected to a cutting knife 49. The cutting knife 49 is used for cutting the protective film. The fourth electric push rod 48 is inclined from the side close to the adjacent T-shaped slider 46 to the side away from the adjacent T-shaped slider 46 and towards the side close to the adjacent arc-shaped rod 43, so that the cutting knife 49 cuts the bottom of the raised protective film that is hooked, for enabling the cutting knife 49 to completely cut the protective film.

[0046] As Figure 8 shown in Figure 8 , a diversion cavity is arranged in the second sliding rod 23. The diversion cavity is communicated with the adjacent second fixed shell 22 and is filled with hydraulic oil. Two symmetrically distributed fifth sliding rods 50 are slidably connected to the side of the second sliding rod 23 away from the adjacent second fixed shell 22. Both of the two fifth sliding rods 50 are located in the diversion cavity of the adjacent second sliding rod 23. During the process of the second sliding rod 23 being squeezed, part of the hydraulic oil in the second fixed shell 22 pushes the adjacent two fifth sliding rods 50 outwards through the diversion cavity. A spring is fixedly connected between the fifth sliding rod 50 and the adjacent second sliding rod 23. This spring is used for resetting the fifth sliding rod 50. A limiting ring is fixedly connected to the side of the second sliding rod 23 away from the adjacent second fixed shell 22. The limiting ring is used for limiting the second sliding rod 23 after it penetrates the protective film. The limiting ring of the second sliding rod 23 is located between the adjacent and symmetrically distributed fifth sliding rods 50 and the adjacent second fixed shell 22, so that after the fifth sliding rod 50 extends out, the protective film is clamped between the fifth sliding rod 50 and the limiting ring. A barb groove 51 is arranged on the side of the fifth sliding rod 50 close to the adjacent second fixed shell 22, for hooking the protective film during the peeling of the protective film to prevent the protective film from detaching between the fifth sliding rod 50 and the limiting ring.

[0047] When the second sliding rod 23 is blocked by the soil ball of the sapling root, the second sliding rod 23 penetrates through the protective film of the soil ball of the sapling root, and the second sliding rod 23 is limited by the limiting ring on the second sliding rod 23 to prevent the second sliding rod 23 from damaging the structure of the soil ball of the sapling root after passing through the protective film. While the second sliding rod 23 slides into the second fixed shell 22 and squeezes the hydraulic oil in the second fixed shell 22, a part of the hydraulic oil enters the diversion cavity of the second sliding rod 23, and pushes the fifth sliding rods 50 symmetrically distributed in the diversion cavity away from each other and squeezes the adjacent springs respectively. At this time, the protective film is located between the fifth sliding rod 50 and the limiting ring on the second sliding rod 23.

[0048] When the telescopic end of the second electric push rod 14 drives the first fixed shell 15 to move upward, the first fixed shell 15 drives all the arc-shaped frames 30 thereon to move upward. Taking the upward movement of one arc-shaped frame 30 and its parts as an example, during the upward movement of the arc-shaped frame 30, the adjacent fourth fixed shells 35 of the arc-shaped frame 30 all come into contact with the soil ball and are blocked by the soil ball, so that the fourth fixed shell 35 squeezes the third fixed shell 32 into the arc-shaped frame 30 through the adjacent third sliding rod 34 and the adjacent diversion shell 33, and compresses the spring between the third fixed shell 32 and the arc-shaped frame 30. After the telescopic end of the second electric push rod 14 extends and closes, the user starts the third electric push rod 36. The telescopic end of the third electric push rod 36 moves upward and drives the fourth sliding rod 38 to move upward. The fourth sliding rod 38 moves upward and drives the gear of the rotating frame 31 to rotate through the rack thereon, so that the rotating frame 31 rotates towards the sapling and the torsion of the torsion spring between the arc-shaped frame 30 and the adjacent rotating frame 31 is gradually released. During this process, the adjacent fourth fixed shells 35 of the rotating frame 31 all come into contact with the soil ball and are blocked by the soil ball, so that the fourth fixed shell 35 squeezes the third fixed shell 32 into the rotating frame 31 through the adjacent third sliding rod 34 and the adjacent diversion shell 33, and compresses the spring between the third fixed shell 32 and the rotating frame 31 until the rack of the fourth sliding rod 38 disengages from the gear of the rotating frame 31 and the rotating frame 31 rotates to the maximum rotation angle and stops, so that the first T-shaped slide rail 44 of the arc-shaped frame 30 is communicated with the second T-shaped slide rail 45 of the rotating frame 31. At this time, the adjacent fourth fixed shells 35 of the arc-shaped frame 30 are all in a fitting state with the protective film on the lower arc surface of the soil ball of the sapling root, and the adjacent fourth fixed shells 35 of the rotating frame 31 are all in a fitting state with the protective film on the upper plane of the soil ball of the sapling root.

[0049] After all the fourth fixed cases 35 are in a fitting state with the protective film of the sapling root ball, the telescopic end of the third electric push rod 36 continues to move upward to contact the adjacent sliding plate 39, pushing the sliding plate 39 upward and compressing the spring between it and the fifth fixed case 37. The hydraulic oil in the fifth fixed case 37 is squeezed by the sliding plate 39, so that the hydraulic oil enters the adjacent fourth fixed case 35 through the oil pipe 40. Taking one of the fourth fixed cases 35 as an example, the hydraulic oil entering the fourth fixed case 35 pushes the sliding block 41 upward. The upward movement of the sliding block 41 squeezes the hydraulic oil between the adjacent elastic oil bag 42, the third sliding rod 34 and the diversion shell 33 of the sliding block 41, causing the elastic oil bag 42 to expand towards the adjacent arc rod 43 and push it out. Furthermore, the side of the arc rod 43 close to the protective film penetrates the protective film and hooks the protective film. After the sliding block 41 is limited by the adjacent elastic oil bag 42 and stops moving, the elastic oil bag 42 stops expanding. At this time, the side of the fourth fixed case 35 close to the oil pipe 40 is communicated with the diversion shell 33 through the third sliding rod 34.

[0050] After the side of the fourth fixed case 35 close to the oil pipe 40 is communicated with the diversion shell 33, the hydraulic oil entering the fourth fixed case 35 again enters the third fixed case 32 through the diversion shell 33 and causes the diversion shell 33 to move away from the sapling root ball. During this process, the diversion shell 33 hooks the protective film through the third sliding rod 34 and the arc rod 43 of the fourth fixed case 35. At the same time, the diversion shell 33 compresses the spring between it and the third fixed case 32. While the springs between all the diversion shells 33 and the third fixed case 32 are compressed, the elastic forces of the springs outside the third fixed case 32 on the arc-shaped frame 30 and the springs outside the third fixed case 32 on the rotating frame 31 are released, causing the third fixed case 32 to gradually return to its initial position. The diversion shell 33 continues to move away from the sapling root ball until the hydraulic oil in the fifth fixed case 37 completely flows out. The user closes the third electric push rod 36. At this time, the positions of the protective film close to the fourth fixed case 35 are all hooked by the arc rods 43, so as to avoid damaging the tree roots on the surface of the sapling root ball during subsequent cutting of the protective film.

[0051] When the positions of the protective film close to the fourth fixed housing 35 are all hooked by the arc-shaped rods 43 and the third electric push rod 36 is closed, the user activates the fourth electric push rod 48. The cutting knife 49 is moved to a position where it can cut the protective film through the telescopic end of the fourth electric push rod 48. Subsequently, the user sets the fourth electric push rod 48 to a mode of telescoping within a short distance, causing the cutting knife 49 to cut the protective film back and forth. After setting the mode of the fourth electric push rod 48, the user activates the electric wheel 47 and controls the two pull ropes fixed to the T-shaped slider 46 through the electric wheel 47, causing the cutting knife 49 to move along the second T-shaped slide rail 45 on the side close to the sapling within the rotating frame 31 towards the side close to the lower part of the root ball of the sapling within the first T-shaped slide rail 44 of the arc-shaped frame 30. By setting the fourth electric push rod 48 obliquely, it drives the cutting knife 49 to cut the bottom of the convex part of the hooked protective film, realizing a complete cut of the protective film of the root ball of the sapling.

[0052] After the protective film of the root ball of the sapling is completely cut, the user switches the mode of the fourth electric push rod 48 to retract the telescopic end and drive the cutting knife 49 away from the root ball of the sapling. Then, the user controls the electric wheel 47 to reverse and reset the T-shaped slider 46 to its initial position within the second T-shaped slide rail 45. Subsequently, the user activates the third electric push rod 36 to gradually retract its telescopic end and drive the fourth sliding rod 38 to move downward. The thrust of the telescopic end of the third electric push rod 36 on the sliding plate 39 upward is released, and the spring elasticity of the sliding plate 39 is released, driving the sliding plate 39 to move downward synchronously in contact with the telescopic end of the third electric push rod 36. The thrust of the sliding plate 39 on the hydraulic oil in the fifth fixed housing 37 disappears, and the thrust on the sliding blocks 41 in all the fourth fixed housings 35 connected to the fifth fixed housing 37 disappears. The spring elasticity between the diversion shell 33 and the third fixed housing 32 is first released, pushing the diversion shell 33 and the third sliding rod 34 out, causing the hydraulic oil in the third fixed housing 32 to be pushed back into the fourth fixed housing 35 through the diversion shell 33. At the same time, the fourth fixed housing 35 re-adheres to the root ball of the sapling and is blocked by the root ball. The fourth fixed housing 35 being blocked by the root ball causes the third sliding rod 34 to stop moving. The spring elasticity in the third fixed housing 32 continues to be released and pushes it away from the root ball of the sapling, compressing the spring outside the third fixed housing 32 until the hydraulic oil in the third fixed housing 32 is completely pushed out. The expanded elastic oil bag 42 gradually recovers and squeezes out the hydraulic oil inside it, driving the arc-shaped rod 43 to retract. The squeezed-out hydraulic oil pushes the sliding block 41 back to its original position. When the sliding plate 39 is reset to its initial position, all the arc-shaped rods 43 adjacent to the fourth fixed housing 35 are retracted and release the hooked protective film. At this time, the rack above the fourth sliding rod 38 re-engages with the gear of the rotating frame 31 and drives the rotating frame 31 to reset to its initial position, and the torsion spring between the arc-shaped frame 30 and the rotating frame 31 is re-energized.

[0053] After the rotating frame 31 is reset to the initial position, the user turns off the third electric push rod 36 and starts the second electric push rod 14. The telescopic end of the second electric push rod 14 retracts and drives the arc-shaped frame 30 and the parts thereon and the first arc-shaped plate 20 and the parts thereon to reset to the initial state through the first fixed housing 15, the third fixing frame 18 and the support rods 19 thereon respectively. During the process of the first arc-shaped plate 20 driving the parts thereon to reset, the barb groove 51 of the fifth sliding rod 50 extending on the second sliding rod 23 will hook the protective film and peel off the cut protective film until the telescopic end of the second electric push rod 14 retracts and stops, completing the cutting and separation of the protective film. Subsequently, the user can remove the separated protective film and continue with the next separation of the protective film.
