Description

Technical Field

[0002] In order to reduce the content of harmful gases and particulate matter in urban air and improve air quality, the method of increasing the area of ​​municipal landscaping is usually adopted nowadays. The methods of municipal landscaping include planting grass, planting trees, cultivating flower beds, etc. Among them, transplanting is mostly used for tree planting. Specifically, the cultivated seedlings are transplanted to the gardens that need greening in a nursery specializing in seedling cultivation. In order to ensure the survival rate of the seedlings during transplantation, a part of the soil is usually retained at the roots when transplanting the seedlings. When digging the seedlings, the soil around the roots is usually dug out together, so that the dug soil is hemispherical, and in order to maintain the structure of the soil ball itself and the moisture in it, a protective film is usually wrapped around the outside of the soil ball.

[0003] After the saplings are transported to the location to be planted, it is usually necessary to first dig a pit for transplanting the saplings, then put the saplings into the pit and backfill the soil. 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 different. It cannot be guaranteed that the pit can adapt to the soil balls at the roots of different saplings. If the pit is too small, it needs to be expanded again.

The guide frame 8 is sealed and slidably connected with two sliding members 10 evenly distributed circumferentially. A spring is fixedly connected between the sliding member 10 and the guide frame 8. The sliding member 10 is equipped with a soil cleaning member 11. The two soil cleaning members 11 cooperate with each other to dig a soil pit in a revolution manner. By changing the amount of hydraulic oil in the guide 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. The support frame 2 is provided with a diameter detection component for detecting the diameter of the soil ball at the root of the tree, and the electric shaft 3 is provided with a fixing component for clamping and carrying the tree.

[0035] like Figure 1 , Figure 2 and Figure 4-Figure 8As shown, the diameter detection assembly includes a second fixing frame 13, the second fixing frame 13 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, a 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, and the spring of the first sliding rod 16 is contracted to To prevent the subsequent support platform 17 from damaging the structure of the soil ball when it moves upward, the telescopic end of the second electric push rod 14 is fixedly connected to the third fixed frame 18, and the third fixed frame 18 is slidably connected to four support rods 19 evenly distributed in the circumference. The support platform 17 is hinged with four first arc-shaped plates 20 evenly distributed in the circumference. The first arc-shaped plates 20 are hinged to the adjacent support rods 19. By moving the third fixed frame 18 upward, the support rods 19 slide, and the support platform 17 is stationary, the first arc-shaped plates 20 are pushed upward, and the soil ball is moved upward. The first arc plate 20 rotates so that the four first arc plates 20 form a hemispherical shape and actively fit the outer surface of the soil ball. The back sides of the four first arc plates 20 are fixed with two equally distributed arc shells 21. The arc shell 21 is connected to an equally distributed second fixed shell 22 on the side facing the support platform 17. Hydraulic oil is filled in the arc shell 21 and the second fixed shell 22. The second fixed shell 22 passes through the adjacent first arc plates 20. The second fixed shell 22 is slidably connected with a second sliding rod 23. The second sliding rod 23 fits the soil ball to change the relative position of the second sliding rod 23 and the adjacent second fixed shell 22, thereby adjusting the amount of hydraulic oil in the second fixed shell 22. The eight arc shells 21 are connected to the annular cavity of the fixed ring 6 through a hose. Through the flow of hydraulic oil in all second fixed shells 22, the amount of hydraulic oil flowing into the annular cavity of the fixed ring 6 is adjusted according to the size of the soil ball to change the distance between the two soil cleaning pieces 11, that is, the diameter of the soil ball is proportional to the amount of hydraulic oil entering the annular cavity of the fixed ring 6.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the fixing assembly 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 on the left and right are hinged on the front side of the fourth fixing frame 25. The front sides of the two second arc-shaped plates 26 are jointly provided with locking members 27 (the locking members 27 are existing locking methods and are not described in detail here). Two equally distributed telescopic rods 28 are fixedly connected to the inner sides of the two second arc-shaped plates 26. The telescopic ends of the telescopic rods 28 are fixedly connected with elastic blocks 29. Springs are fixedly connected between the elastic blocks 29 and the adjacent second arc-shaped plates 26. The elastic blocks 29 are used to contact with the tree trunk. The elasticity of the elastic blocks 29 and the expansion and contraction of the adjacent springs are utilized to adapt to the shape of the tree trunk so as to fix the tree trunk.

[0037] When it is necessary to use the device to assist in planting saplings, the user unlocks the locking piece 27 and rotates the two second curved plates 26 to separate them, then places the soil ball at the root of the sapling on the support platform 17, rotates the two second curved plates 26 to reset them, and re-locks the locking piece 27 to keep the two second curved plates 26 relatively stable. During the rotation and reset of the two second curved plates 26, the four elastic blocks 29 gradually contact the saplings and are limited by the saplings to squeeze the telescopic parts of adjacent telescopic rods 28 respectively. During the movement of the elastic block 29, the spring of the elastic block 29 is squeezed, and the elastic block 29 changes its own shape according to the shape of the sapling to ensure the stability of the sapling.

[0038] After the saplings are fixed, the user starts the transport vehicle 1 and the second electric push rod 14, and transports the saplings to the position to be planted by the transport vehicle 1, and positions the two soil-clearing pieces 11 just above the position to be planted, and then stops the transport vehicle 1. During this process, the telescopic end of the second electric push rod 14 moves upward, and drives the first fixed shell 15 and the third fixed frame 18 to move upward together. During the upward movement of the first fixed shell 15, the first fixed shell 15 gradually squeezes the spring of the first sliding rod 16, so that the position of the first sliding rod 16 and the support platform 17 is adjusted. The third fixing frame 18 is stable, and when the third fixing frame 18 moves upward, it drives the four support rods 19 evenly distributed in the circumferential direction to move upward. During the upward movement of the support rods 19, the support rods 19 slide along the third fixing frame 18 toward the first fixing shell 15, and the support rods 19 and the adjacent first arc-shaped plates 20 rotate. The first arc-shaped plates 20 and the support platform 17 rotate, so that the four first arc-shaped plates 20 gather together, and 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 is extended, and then the second electric push rod 14 is closed.

[0039] When the first arc plate 20 approaches the soil ball, the second sliding rod 23 contacts the soil ball and is blocked by the soil ball, so that the second sliding rod 23 slides into the adjacent second fixed shell 22, and the second sliding rod 23 pushes the hydraulic oil in the adjacent second fixed shell 22 into the adjacent arc shell 21, and is introduced into the annular cavity of the fixed ring 6 by the adjacent hose. Then the hydraulic oil enters the guide frame 8 through the hose on the swivel 7, and pushes the two sliding members 10 outward, so that the sliding members 10 squeeze the adjacent springs, and the sliding members 10 drive the adjacent soil cleaning members 11 to move to change the subsequent pit digging size. Through the contact between all the second sliding rods 23 and 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 pit digging size is changed according to the size of the soil ball, thereby avoiding the generation of extra workload due to inappropriate pit digging size and improving 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, which drives the fourth fixing frame 25 and its parts and the sapling to move upward until the sapling is free from the limit of the second fixing frame 13. The user stops the electric slide rail 24 and starts the electric shaft 3. The electric shaft 3 rotates to rotate the first fixing frame 4 and the fourth fixing frame 25 and its parts and the sapling together until the sapling is located directly above the soil pit to be planted. Then the user stops the electric shaft 3. , and start 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 in the soil pit to be planted, and then the user stops the electric slide rail 24 and unlocks the locking piece 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 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 this cycle is repeated.

[0043] Embodiment 2: Based on embodiment 1, Figure 2 , Figure 4 , Fig. 9 , Fig.10 , Fig.12 and Fig.13As shown, a separation component is also included, which is arranged on the first fixed shell 15. The separation component is used to separate the protective film from the soil ball. The separation component includes four arc frames 30 uniformly distributed in the circumferential direction. The four arc frames 30 are all fixed to the middle part of the outer peripheral side of the first fixed shell 15. The four arc frames 30 are staggered with the four first arc plates 20, so that the four arc frames 30 correspond to the gaps between the four first arc plates 20 after the four first arc plates 20 fit the soil ball. The upper side of the arc frame 30 is rotatably connected with a rotating frame 31, and the facing sides of the four arc frames 30 and the four rotating frames 31 are slidably connected with equidistantly distributed third fixed shells 32. The third fixed shells 32 in the arc frames 30 and the rotating frames 31 are contracted to adapt to different diameters of the soil balls. Springs are fixed between the arc frames 30 and the rotating frames 31 and the adjacent third fixed shells 32, respectively, and the springs are used to reset the third fixed shells 32. 2 is sealed and slidably connected with a guide shell 33, which is located on the side of the third fixed shell 32 close to the sapling. A spring is fixedly connected between the guide shell 33 and the adjacent third fixed shell 32, and the spring is used to reset the adjacent guide shell 33. The guide shell 33 is fixedly connected and connected with a third sliding rod 34. The guide shell 33 and the adjacent third sliding rod 34 form a hydraulic oil transmission path and are filled with hydraulic oil. The side of the guide shell 33 close to the adjacent third sliding rod 34 is provided with guide holes that are evenly distributed in the circumference and are connected with its own cavity. The third sliding rod 34 is sealed and slidably connected with the adjacent third fixed shell 32, so that the hydraulic oil entering the adjacent third fixed shell 32 through the guide shell 33 pushes the adjacent guide shell 33 and the adjacent third sliding rod 34 to move in a direction away from the sapling. The side of the third sliding rod 34 away from the adjacent third fixed shell 32 is connected with a fourth fixed shell 35, and the fourth fixed shell 35 is filled with hydraulic oil.

[0044] like Figure 9-13As shown, 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 sealed 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 sealed and slidably connected in the fifth fixed shell 37, and a spring is fixedly connected therebetween. The sliding plate 39 is located at the lower side of 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 sealed 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 connected to the adjacent third electric push rod 36. The telescopic end of the push rod 36 is limited and matched. 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. A rack is installed on the upper side of the fourth sliding rod 38. The gear is meshed 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 gear installed on the rotating shaft of the rotating frame 31 and the adjacent arc frame 30. The torsion spring is initially in a stored force state. The fifth fixed shell 37 is connected to an oil pipe 40, and hydraulic oil is filled in the oil pipe 40. The fourth fixed shell 35 is connected to the adjacent oil pipe 40, and the hydraulic oil in the fifth fixed shell 37 is transmitted to the adjacent fourth fixed shell 37 through the adjacent oil pipe 40. In the four fixed shells 35, a sliding block 41 is slidably connected to a side of the fourth fixed shell 35 close to the adjacent oil pipe 40, an elastic oil bag 42 is fixedly connected to a side of the fourth fixed shell 35 away from the adjacent oil pipe 40, and an arc rod 43 is slidably connected to a side of the fourth fixed shell 35 away from the adjacent sliding block 41. The elastic oil bag 42 is located between the adjacent sliding block 41 and the arc rod 43. The elastic oil bag 42 is fixedly connected to the adjacent arc rod 43. The opening of the elastic oil bag 42 faces downward and limits the maximum movement 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 guide 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 , so that the elastic oil bag 42 expands, and the elastic oil bag 42 expands to push out the adjacent arc rod 43 so that the arc 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 guide shell 33 and the adjacent third fixed shell 32, and the elastic coefficient of the outer spring of the third fixed shell 32 is less than the elastic coefficient of the spring between the guide shell 33 and the adjacent third fixed shell 32, so that the outer spring of the third fixed shell 32 is compressed before the spring between the guide shell 33 and the adjacent third fixed shell 32. When the spring between the guide shell 33 and the adjacent third fixed shell 32 is compressed, the outer spring of the third fixed shell 32 gradually stretches and resets to ensure that the guide shell 33 can slide smoothly in the adjacent third fixed shell 32 to hook the protective film.

[0045] like Fig.10 , Fig.12 and Fig.14 As shown, the opposite sides of the circumferentially evenly distributed arc-shaped frames 30 are provided with first T-shaped rails 44, and the opposite sides of the circumferentially evenly distributed rotating frames 31 are provided with second T-shaped rails 45. The first T-shaped rails 44 and the adjacent second T-shaped rails 45 are combined into a continuous track after the adjacent rotating frames 31 rotate to a specified angle. A T-shaped slider 46 that is slidably connected to the adjacent first T-shaped rail 44 is slidably connected in the second T-shaped rail 45. The T-shaped slider 46 is initially located at the uppermost side of the adjacent second T-shaped rail 45. An electric wheel 47 is installed on the side of the arc-shaped frame 30 close to the first fixed shell 15. The electric wheel 47 can be bidirectionally The driving force for rotation, the electric wheel 47 is fixedly connected to the two sides of the adjacent T-shaped slider 46 through two pull ropes, which is used to control the T-shaped slider 46 to slide in the assembled T-shaped slide rail. A fourth electric push rod 48 is fixedly connected to the T-shaped slider 46, and a cutting knife 49 is fixedly connected to the telescopic end of the fourth electric push rod 48. The cutting knife 49 is used to cut the protective film. The fourth electric push rod 48 tilts from the side close to the adjacent T-shaped slider 46 to the side away from the adjacent T-shaped slider 46 to the side close to the adjacent arc rod 43, so that the cutting knife 49 cuts the bottom of the protrusion of the hooked protective film, so as to enable the cutting knife 49 to completely cut the protective film.

[0046] like Figure 8 As shown, a guide cavity is provided in the second sliding rod 23, which is communicated with the adjacent second fixed shell 22 and is filled with hydraulic oil. The second sliding rod 23 is slidably connected to one side away from the adjacent second fixed shell 22 with two symmetrically distributed fifth sliding rods 50. The two fifth sliding rods 50 are both located in the guide cavity of the adjacent second sliding rod 23. In the process of the second sliding rod 23 being squeezed, part of the hydraulic oil in the second fixed shell 22 pushes the two adjacent fifth sliding rods 50 outward through the guide cavity. A spring is fixedly connected between the fifth sliding rod 50 and the adjacent second sliding rod 23, and the spring is used to make the fifth sliding rod 50 The rod 50 is reset, and the second sliding rod 23 is fixedly connected to a limiting ring on one side away from the adjacent second fixed shell 22. The limiting ring is used to limit the second sliding rod 23 after penetrating the protective film. The limiting ring of the second sliding rod 23 is located between the adjacent and symmetrically distributed fifth sliding rod 50 and the adjacent second fixed shell 22, so that the fifth sliding rod 50 clamps the protective film between the fifth sliding rod 50 and the limiting ring after extending. The fifth sliding rod 50 is provided with a barb groove 51 on one side close to the adjacent second fixed shell 22, which hooks the protective film when peeling off to prevent the protective film from detaching from between the fifth sliding rod 50 and the limiting ring.

[0047] When the second sliding rod 23 is blocked by the soil ball at the root of the sapling, the second sliding rod 23 passes through the protective film of the soil ball at the root of the sapling, 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 at the root of the sapling after passing through the protective film. While the second sliding rod 23 slides into the second fixed shell 22 to squeeze the hydraulic oil in the second fixed shell 22, a part of the hydraulic oil enters the guide cavity of the second sliding rod 23, pushing the fifth sliding rod 50 symmetrically distributed in the guide cavity in the direction away from each other and squeezing the adjacent springs respectively. At this time, the protective film is located between the fifth sliding rod 50 and the limiting rings 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 frames 30 thereon to move upward. Taking the action of one of the arc frames 30 and the parts thereon moving upward as an example, in the process of the arc frame 30 moving upward, the fourth fixed shell 35 adjacent to the arc frame 30 all contacts the soil ball and is blocked by the soil ball, so that the fourth fixed shell 35 squeezes the third fixed shell 32 into the arc frame 30 through the adjacent third sliding rod 34 and the adjacent guide shell 33, and compresses the spring between the third fixed shell 32 and the arc frame 30. After the telescopic end of the second electric push rod 14 is extended and closed, 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 The fourth fixed shell 35 adjacent to the rotating frame 31 contacts the soil ball and is 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 guide 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 is disengaged 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 frame 30 is connected to the second T-shaped slide rail 45 of the rotating frame 31. At this time, the fourth fixed shell 35 adjacent to the arc frame 30 is in a fit state with the protective film on the lower arc surface of the soil ball at the root of the seedling, and the fourth fixed shell 35 adjacent to the rotating frame 31 is in a fit state with the protective film on the upper plane of the soil ball at the root of the seedling.

[0049] After all the fourth fixed shells 35 are in a state of being attached to the protective film of the soil ball at the root of the sapling, the telescopic end of the third electric push rod 36 continues to move upward and contacts the adjacent sliding plate 39, pushing the sliding plate 39 upward and compressing the spring between it and the fifth fixed shell 37. The hydraulic oil in the fifth fixed shell 37 is squeezed by the sliding plate 39, so that the hydraulic oil enters the adjacent fourth fixed shell 35 through the oil pipe 40. Taking one of the fourth fixed shells 35 as an example, the hydraulic oil entering the fourth fixed shell 35 pushes the sliding block 41 upward The sliding block 41 moves upward to squeeze the hydraulic oil between the adjacent elastic oil bag 42 of the sliding block 41, the third sliding rod 34 and the guide shell 33, so that the elastic oil bag 42 expands in the direction of the adjacent arc rod 43 and pushes it out, thereby causing the arc rod 43 to penetrate the protective film on the side close to the protective film and hook 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 shell 35 close to the oil pipe 40 is connected with the guide shell 33 through the third sliding rod 34.

[0050] After the side of the fourth fixed shell 35 close to the oil pipe 40 is connected with the guide shell 33, the hydraulic oil entering the fourth fixed shell 35 enters the third fixed shell 32 through the guide shell 33 and moves the guide shell 33 away from the soil ball at the root of the sapling. In this process, the guide shell 33 hooks up the protective film through the third sliding rod 34 and the arc rod 43 of the fourth fixed shell 35, and at the same time, the guide shell 33 compresses the spring between it and the third fixed shell 32. At the same time, all the springs between the guide shell 33 and the third fixed shell 32 are compressed. When the hydraulic oil in the fifth fixed shell 37 is completely discharged, the user closes the third electric push rod 36. At this time, the protective film near the fourth fixed shell 35 is hooked up by the arc rod 43, so that the roots of the tree on the surface of the soil ball at the root of the sapling are avoided when the protective film is cut later.

[0051] After the protective film is hooked up by the arc rod 43 at the position close to the fourth fixed shell 35 and the third electric push rod 36 is closed, the user starts the fourth electric push rod 48 and moves the cutting knife 49 to a position where the protective film can be cut through the telescopic end of the fourth electric push rod 48. Then the user sets the fourth electric push rod 48 to a telescopic mode within a short distance, so that the cutting knife 49 cuts the protective film back and forth. After setting the mode of the fourth electric push rod 48, the user starts the electric wheel 47 and controls the two pull ropes fixed to the T-shaped slider 46 through the electric wheel 47 to move the cutting knife 49 along the side of the second T-shaped slide rail 45 in the rotating frame 31 close to the sapling toward the side of the first T-shaped slide rail 44 in the arc frame 30 close to the bottom of the soil ball under the root of the sapling. By tilting the fourth electric push rod 48, it drives the cutting knife 49 to cut the bottom of the protrusion that hooks up the protective film, thereby achieving complete cutting of the protective film of the soil ball at the root of the sapling.

[0052] After the protective film of the soil ball at the root 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 soil ball at the root of the sapling, and then controls the electric wheel 47 to reverse and reset the T-shaped slider 46 to the initial position in the second T-shaped slide rail 45. Then the user starts the third electric push rod 36 to gradually retract its telescopic end and drive the fourth sliding rod 38 to move downward. The retraction of the telescopic end of the third electric push rod 36 releases the upward thrust of the sliding plate 39, and the spring force of the sliding plate 39 is released to drive the sliding plate 39 to move downward synchronously 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 shell 37 disappears, and the thrust of the sliding blocks 41 in all the fourth fixed shells 35 connected to the fifth fixed shell 37 disappears. The spring force between the guide shell 33 and the third fixed shell 32 is released first, and the guide shell 33 and the third sliding rod 34 are pushed out, so that the third fixed shell 32 The hydraulic oil in the third fixed shell 32 is pushed back into the fourth fixed shell 35 through the guide shell 33. At the same time, the fourth fixed shell 35 is again attached to the soil ball at the root of the sapling and is blocked by the soil ball. The fourth fixed shell 35 is blocked by the soil ball, causing the third sliding rod 34 to stop moving. The spring force in the third fixed shell 32 continues to be released and pushes it in the direction away from the soil ball at the root of the sapling, and compresses the spring outside the third fixed shell 32. Until the hydraulic oil in the third fixed shell 32 is completely pushed out, the expanded elastic oil bag 42 gradually recovers to squeeze out the hydraulic oil inside it and drive the arc rod 43 to retract. The squeezed hydraulic oil pushes the sliding block 41 back to its original position. When the sliding plate 39 is reset to the initial position, the adjacent arc rods 43 of the fourth fixed shell 35 are all retracted and the hooked protective film is released. At this time, the rack above the fourth sliding rod 38 is re-engaged with the gear of the rotating frame 31 and drives the rotating frame 31 to return to its initial position, and the torsion spring between the arc frame 30 and the rotating frame 31 is re-charged.

[0053] After the rotating frame 31 is reset to the initial position, the user closes the third electric push rod 36 and starts the second electric push rod 14. The telescopic end of the second electric push rod 14 is retracted and drives the arc frame 30 and the parts thereon and the first arc plate 20 and the parts thereon to reset to the initial state through the first fixed shell 15 and the third fixed frame 18 and the support rod 19 thereon respectively. During the process of the first arc plate 20 driving the parts thereon to reset, the hook groove 51 of the fifth sliding rod 50 extending from 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 is retracted and stopped, completing the cutting and separation of the protective film. Subsequently, the user removes the separated protective film and can continue to separate the protective film next time.
