Landscape garden tree planting pit digging equipment

Abstract

This invention discloses a landscape tree planting pit excavation device, including a base frame with wheels at the rear end connected to it by angle steel. It also includes a folding frame, an excavation adjustment mechanism, an adjustment frame mechanism, a soil collection mechanism, and a pit-digging mechanism. This invention utilizes the splicing of two semi-circular collection cylinders fitted onto a spiral drill rod. During pit digging, the spiral drill rod pushes the excavated soil up along two sealing plates, collecting it into the semi-circular collection cylinders through an annular opening between the sealing plates and a conical cover plate. This effectively avoids soil splashing and the problem of soil burying lawns. Furthermore, the unfolding of the semi-circular collection cylinders and the lateral movement of the spiral drill rod, along with the fitting of the semi-circular collection cylinders onto the trees after transplanting, allows for rapid soil backfilling, improving backfilling efficiency.

Description

Technical Field

[0001] This invention relates to the field of landscaping and planting technology, and in particular to a device for excavating planting pits for landscape trees. Background Technology

[0002] In the process of landscaping, digging planting pits is an essential step. In addition to manual digging, mechanical digging equipment can also be used to dig planting pits, which can effectively improve digging efficiency. Then, workers can put the trees into the planting pits and fill them back with soil, thus completing the planting of the trees.

[0003] Currently, existing excavation equipment still has certain shortcomings. During the excavation of planting pits, the drill bit is usually driven down directly to excavate, and soil will also be splashed around during the excavation process, scattering soil around the planting pit and burying the surrounding lawn. This means that backfilling can only be done slowly by hand, and it is also very easy to damage the lawn, resulting in poor performance. Therefore, there is an urgent need to design a tree planting pit excavation equipment for landscape gardening to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a landscape tree planting pit excavation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A landscape tree planting pit excavation device includes a base frame, with wheels mounted at the rear end of the base frame and connected to the base frame via angle steel. It also includes:

[0007] The folded frame is mounted on the base frame and is centrally symmetrically distributed, with a handle at the top.

[0008] The excavation adjustment mechanism, located between two folded frames, includes:

[0009] The adjusting seat is located at the upper inner side of the folded frame. A gate-shaped sliding seat is installed on its outer surface. The gate-shaped sliding seat is vertically set and slides on the folded frame. A concave sliding seat is located on its inner surface. The concave sliding seat is horizontally set.

[0010] The lifting screw is installed on the upper outer side of the folded frame and inserted into the portal sliding seat, and is threadedly connected to the portal sliding seat. The lower end of the screw is equipped with a lifting motor, which is fixedly connected to the folded frame.

[0011] A horizontal adjustment frame is slidably set inside a concave sliding seat, and a horizontal screw is set on its outer side. The horizontal screw is inserted into the concave sliding seat and threadedly connected to the concave sliding seat.

[0012] Adjustment frame mechanism, located at both ends of the front of the base frame, includes:

[0013] The adjustment frame is located at both ends of the front of the base frame and is movably hinged to the base frame through a rotating seat, so that the adjustment frame can swing horizontally on the base frame. A caster wheel is installed at one of its lower ends.

[0014] A fixed bracket is installed above the adjustment frame, and an electric push rod is installed on it. The electric push rod can adjust the height of the fixed bracket.

[0015] The adjusting push rod is located between the adjusting frame and the base frame and is connected by a rotating seat;

[0016] A soil collection mechanism, mounted on an adjusting frame, includes:

[0017] A semi-circular collecting cylinder is set on one side above the adjusting frame and connected to the fixed bracket. Its outer surface is conical, its side surface is open, and a conical cover plate is installed at the top. Sliding short shafts are set at the top of both ends inside.

[0018] The sealing plate is slidably embedded in the open opening on the side surface of the semi-circular collecting cylinder and blocks the open opening of the semi-circular collecting cylinder. The middle part is semi-circular and the two ends are flat. Sliding ear plates are provided at both ends above the side surface. The sliding ear plates are fitted on the sliding short shaft.

[0019] An arc-shaped adjusting plate is located above the conical cover plate, and an adjusting rod is installed between it and the sealing plate;

[0020] A semi-circular cone seat is installed at the lower end of a semi-circular collecting cylinder;

[0021] The hole-digging mechanism is located between two horizontal adjustment frames.

[0022] According to the above scheme, the digging mechanism includes a digging platform disposed between two horizontal adjustment frames. The digging platform is located at one end of the horizontal adjustment frames and is fixedly connected to the two horizontal adjustment frames. A horizontal motor is installed on the side surface of the digging platform. The horizontal motor is connected to the horizontal screw through a bevel gear. A digging drive mechanism is installed on the digging platform. A spiral drill rod is installed below the digging platform and is connected to the digging drive mechanism.

[0023] According to the above schemes, the retraction of the adjusting push rod drives the adjusting frame to move toward the auger drill rod, so that the two semi-circular collecting cylinders are joined together to form an annular cylinder.

[0024] According to the above schemes, the lower end of the auger rod is inserted into the annular cylinder formed by the docking of two semi-circular collecting cylinders, and the diameter of the auger rod is smaller than the inner diameter of the central semi-circle of the sealing plate.

[0025] According to the above schemes, the adjusting push rod extends and drives the adjusting frame to move outward from the base frame, so that the two semi-circular collecting cylinders separate, thereby enabling the digging mechanism to move laterally with the rotation of the transverse screw, so that the auger drill rod can be moved out of the annular cylinder formed after the two semi-circular collecting cylinders are joined together.

[0026] According to the above schemes, the lower end of the sealing plate contacts the semi-annular cone seat, and the upper end of the sealing plate is flush with the upper end of the semi-circular collection cylinder, so that the soil removed from the pit can enter the semi-circular collection cylinder through the annular opening between the sealing plate and the cone cover plate.

[0027] According to the above schemes, when the auger drill rod is lowered to the lowest position, the uppermost end of the auger blades on it is still above the conical cover plate.

[0028] According to the above schemes, the volume of the two semi-circular collection cylinders is greater than the volume of the planting pit drilled by the auger rod.

[0029] Beneficial effects

[0030] A landscape tree planting pit excavation device manufactured using the technical solution of the present invention has the following beneficial effects:

[0031] 1. This invention utilizes the splicing of two semi-circular collection cylinders, which are fitted onto a spiral drill rod. When the spiral drill rod is digging a hole, the soil generated during excavation rises along two sealing plates and is then collected into the semi-circular collection cylinder through the annular opening between the sealing plate and the conical cover plate. This effectively avoids soil splashing and the problem of soil burying the lawn, while also facilitating soil backfilling.

[0032] 2. This invention utilizes an adjusting frame to move the semi-circular collecting cylinders, allowing the digging mechanism to be moved away from the planting pit, thus facilitating the transplanting of garden trees. Simultaneously, the adjusting frame places two semi-circular collecting cylinders onto the trees, and the upward movement of the sealing plate allows soil to be quickly backfilled into the planting pit, effectively facilitating soil backfilling. Furthermore, during tree transplanting, the positional relationship between the tree and the semi-circular collecting cylinders can be observed to ensure straighter tree transplanting.

[0033] 3. In this invention, the excavated soil is collected by a semi-circular collection cylinder, and the topsoil and deep soil are loaded in reverse order, so that the topsoil can be buried at the tree roots. In this way, the fertility of the topsoil is utilized to help the tree roots absorb nutrients and improve their survival rate. Attached Figure Description

[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0051] See Figures 1-6 A landscape tree planting pit excavation device includes a base frame 1 with wheels 11 at the rear end, connected to the base frame by angle steel. It also includes: folding frames 12, mounted on the base frame 1 and symmetrically distributed centrally, with handles at their upper ends; and an excavation adjustment mechanism 2, positioned between the two folding frames 12, comprising: an adjustment seat 21 located at the upper inner side of the folding frame 12, with a portal sliding seat 211 mounted on its outer surface. The portal sliding seat 211 is vertically positioned and slidably fitted onto the folding frame 12, with its inner surface concave. A concave sliding seat 212 is horizontally positioned; a lifting screw 22 is installed on the upper outer side of the folded frame 12 and inserted into the folded sliding seat 211, and threadedly connected to the folded sliding seat 211; a lifting motor 221 is installed at its lower end and is fixedly connected to the folded frame 12; a transverse adjustment frame 23 is slidably positioned inside the concave sliding seat 212, and a transverse screw 231 is installed on its outer side, inserted into the concave sliding seat 212 and threadedly connected to the concave sliding seat 212;

[0052] In this embodiment of the invention, the folded frame 12 facilitates the installation of the lifting motor 221, making it easier to connect with the lifting screw 22.

[0053] In this embodiment of the invention, the setting of the adjusting seat 21 allows it to slide onto the folded frame 12 using the portal sliding seat 211, and its height can be adjusted by the rotation of the lifting screw 22, thus facilitating the digging mechanism 5 to dig holes. On the other hand, the sliding cooperation between the concave sliding seat 212 and the horizontal adjusting frame 23, and the rotation of the horizontal screw 231, can adjust the position of the digging mechanism 5, allowing it to move away from the planting hole, thus facilitating the transplanting of garden seedlings and the backfilling of soil.

[0054] In this embodiment of the invention, the sliding engagement between the concave sliding seat 212 and the transverse adjustment frame 23, and the threaded connection between the transverse screw 231 and the concave sliding seat 212, can ensure the stability of the transverse adjustment frame 23, so that the digging mechanism 5 can be set stably, thereby ensuring the stability during digging.

[0055] In this embodiment of the invention, the shape of the adjusting seat 21 can be set to be circular or cross-shaped to facilitate the installation of the concave sliding seat 212 and the gate-shaped sliding seat 211. At the same time, an oblique sliding rod can be set inside the adjusting seat 21 so that it slides in contact with the lower surface of the horizontal adjusting frame 23, thereby providing sliding support for the horizontal adjusting frame 23 and ensuring that the horizontal adjusting frame 23 can be stably supported to ensure the stability of the digging mechanism 5.

[0056] In this embodiment of the invention, the lateral adjustment frame 23 is slidably embedded in the concave sliding seat 212. The connection method can also adopt the same connection method between the gate-shaped sliding seat 211 and the folded frame 12, thereby making the hole-digging mechanism 5 more stable and firm, and avoiding the situation where the folded frame 12 bends, causing the lateral screw 231 to bend.

[0057] See Figure 7 The adjustment frame mechanism 3 is located at both ends of the front of the base frame 1. It includes: an adjustment frame 31, located at both ends of the front of the base frame 1 and hinged to the base frame 1 via a rotating seat, allowing the adjustment frame 31 to swing horizontally on the base frame 1, with a caster wheel 311 at one of its lower ends; a fixed bracket 32, located above the adjustment frame 31, with an electric push rod 321 mounted on it, which can adjust the height of the fixed bracket 32; and an adjustment push rod 33, located between the adjustment frame 31 and the base frame 1 and connected via a rotating seat.

[0058] In this embodiment of the invention, the adjustment frame 31 is connected to the base frame 1 via a rotating seat, and the universal wheel 311 below it allows the adjustment frame 31 to swing left and right at the front end of the base frame 1 by means of the extension and retraction of the adjustment push rod 33, thereby facilitating the docking and separation of the semi-circular collection cylinder 41, so as to facilitate the position adjustment of the digging mechanism 5 and enable the seedlings to be quickly transplanted into the planting pit.

[0059] In this embodiment of the invention, an electric push rod 321 is provided on the fixed bracket 32, which can adjust the height of the fixed bracket 32, thereby adjusting the height of the semi-circular collection cylinder 41, so that it can quickly contact and separate from the ground, preventing soil from leaking out of the planting pit during the digging process of the digging mechanism 5, and also facilitating the swing adjustment of the adjustment frame 31.

[0060] See Figure 8-10The soil collection mechanism 4 is mounted on the adjusting frame 31 and includes: a semi-circular collection cylinder 41, which is located on one side above the adjusting frame 31 and connected to the fixed bracket 32. Its outer surface is conical, its side surface is open, and a conical cover plate 411 is installed at the upper end. Sliding short shafts 412 are provided above both ends of its interior. A sealing plate 42 is slidably embedded in the open opening of the side surface of the semi-circular collection cylinder 41 and blocks the open opening of the semi-circular collection cylinder 41. Its middle part is semi-circular, and its two ends are flat. Sliding ear plates 421 are provided above both ends of its side surface. The sliding ear plates 421 are fitted onto the sliding short shafts 412. An arc-shaped adjusting plate 43 is located above the conical cover plate 411 and an adjusting rod 431 is installed between it and the sealing plate 42. A semi-annular cone seat 44 is installed at the lower end of the semi-circular collection cylinder 41.

[0061] In this embodiment of the invention, the arrangement of two semi-circular collecting cylinders 41 and the sealing plate 42 allows the semi-circular collecting cylinders 41 to quickly connect with the adjusting frame 31 as it moves, forming a circular collecting cylinder. The circle at the center of the cylinder is formed by connecting the semi-circles at the center of the sealing plate 42. Then, the spiral drill rod 54 is inserted into the circular cylinder, and the digging work is carried out by lifting. The soil dug out by the spiral drill rod 54 can be quickly collected into the circular collecting cylinder, effectively preventing soil leakage outside the planting pit and thus preventing soil from burying the lawn. At the same time, it can also allow the soil to be quickly backfilled, making it convenient for workers to use and making the transplanting of garden trees more convenient and faster, thus improving the transplanting efficiency.

[0062] In this embodiment of the invention, the conical cover plate 411 is provided to cover the upper end of the semi-circular collection cylinder 41, and the sealing plate 42 seals the open side surface of the semi-circular collection cylinder 41, but the conical cover plate 411 is not sealed. During the drilling process, the soil rises with the auger rod 54 and moves to the annular opening of the conical cover plate 411. The rotation of the auger rod 54 causes the soil to be quickly thrown into the area below the conical cover plate 411. The rebound of the conical cover plate 411 causes the soil to be collected in the semi-annular cylinder formed by the semi-circular collection cylinder 41 and the sealing plate 42.

[0063] In this embodiment of the invention, the sealing plate 42 is adjusted up and down on the semi-circular collection cylinder 41 by sliding the sliding ear plate 421 and the sliding short shaft 412. There can be multiple sliding ear plates 421 to ensure that the sealing plate 42 will not shift, thereby avoiding collision with the auger rod 54, and also ensuring the tightness of the semi-circular collection cylinder 41 sealing to prevent soil from falling.

[0064] In this embodiment of the invention, the arc-shaped adjusting plate 43 is raised, which in turn drives the sealing plate 42 to rise via the adjusting rod 431. This opens the lower end of the semi-circular collecting cylinder 41, allowing soil to be discharged through the opening at the lower end of the semi-circular collecting cylinder 41. This enables the soil to be backfilled quickly, improves the backfilling efficiency, and reduces the workload of the workers.

[0065] In this embodiment of the invention, during the excavation of the planting pit, the surface soil is excavated first as the auger 54 digs out and enters the semi-circular collection cylinder 41 as the auger 54 rotates. The deeper soil is then excavated and stored in the semi-circular collection cylinder 41, so that the surface soil is below the deeper soil. This allows the surface soil to be backfilled to the roots of the garden trees, thus utilizing the fertility of the surface soil to facilitate nutrient absorption by the roots of the garden trees and improve the survival rate of transplanted trees.

[0066] In this embodiment of the invention, the semi-circular cone seat 44 is inserted into the soil by connecting with the semi-circular collection cylinder 41 and by the retraction of the electric push rod 321. This allows the soil generated during digging to be collected into the semi-circular collection cylinder 41 to the maximum extent, preventing soil leakage outside the planting pit and ensuring the stability of the semi-circular collection cylinder 41 on the ground.

[0067] See Figure 4 The digging mechanism 5 is disposed between two horizontal adjustment frames 23. It includes a digging platform 51 disposed between the two horizontal adjustment frames 23. The digging platform 51 is located at one end of the horizontal adjustment frames 23 and is fixedly connected to the two horizontal adjustment frames 23. A horizontal motor 52 is installed on the side surface of the digging platform 51. The horizontal motor 52 is connected to the horizontal screw 231 through a bevel gear. A digging drive mechanism 53 is installed on the digging platform 51. A spiral drill rod 54 is installed below the digging platform 51 and is connected to the digging drive mechanism 53.

[0068] In this embodiment of the invention, the digging mechanism 53 drives the rotation of the spiral drill rod 54 to dig planting pits. The operation of the horizontal motor 52 allows the digging platform 51 to adjust its position according to the operation of the horizontal screw 231. After the planting pit is dug, the digging mechanism 5 can move away from the top of the planting pit, which facilitates the transplanting of garden trees and the backfilling of soil.

[0069] In this embodiment of the invention, the lifting screw 22 and the transverse screw 231 can be threaded screws or reciprocating screws. When using a threaded screw, the height can be adjusted up and down and the horizontal position can be adjusted by controlling the forward and reverse rotation of the motor. When using a reciprocating screw, the height and horizontal position of the digging mechanism 5 can be controlled by keeping the motor rotating in one direction and controlling its working time.

[0070] In this invention, the retraction of the adjusting push rod 33 drives the adjusting frame to move toward the spiral drill rod 54, so that the two semi-circular collecting cylinders 41 are joined together to form an annular cylinder; this allows the soil excavated during digging to rise inside the annular cylinder and be collected inside the annular cylinder.

[0071] In this invention, the lower end of the spiral drill rod 54 is inserted into the annular cylinder formed by the docking of two semi-circular collection cylinders 41, and the diameter of the spiral drill rod 54 is smaller than the inner diameter of the central semi-circle of the sealing plate 42. The smaller diameter of the spiral drill rod 54 than the inner diameter of the central semi-circle of the sealing plate 42 can prevent the spiral drill rod 54 from colliding with the sealing plate 42, and at the same time, it can make the soil generated during digging rise along the cylinder formed by the sealing plate 42 and be collected into the semi-circular collection cylinder 41.

[0072] In this invention, the adjusting push rod 33 extends and drives the adjusting frame 31 to move outward from the base frame 1, so that the two semi-circular collecting cylinders 41 separate, thereby enabling the digging mechanism 5 to move laterally with the rotation of the transverse screw 231, so that the spiral drill rod 54 moves out of the annular cylinder formed after the two semi-circular collecting cylinders 41 are joined together.

[0073] In this invention, the lower end of the sealing plate 42 contacts the semi-annular cone seat 44, and the upper end of the sealing plate 42 is flush with the upper end of the semi-circular collection cylinder 41, so that the soil removed from the pit can enter the semi-circular collection cylinder 41 through the annular opening between the sealing plate 42 and the cone-shaped cover plate 411; ensuring that the soil can be stably collected into the semi-annular cylinder formed by the semi-circular collection cylinder 41 and the sealing plate 42.

[0074] In this invention, when the spiral drill rod 54 descends to its lowest position, the uppermost end of the spiral blades on it remains above the conical cover plate 411; this ensures that the soil excavated by the spiral drill rod 54 during the digging process can be stably collected into the semi-circular collection cylinder 41, preventing the excavated soil from falling back into the planting pit.

[0075] In this invention, the volume of the two semi-circular collection cylinders 41 is greater than the volume of the planting pit drilled by the auger rod 54; this ensures that the semi-circular collection cylinders 41 can collect all the excavated soil and prevent it from scattering outside the semi-circular collection cylinders 41.

[0076] During the implementation of this technical solution, those skilled in the art need to connect all electrical components in this case to an external power generation mechanism, and should select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle below, where the electrical components work sequentially to complete the electrical connection. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not explain the electrical control.

[0077] When using this invention, the following steps are adopted:

[0078] S1: Push the base frame 1 to start moving by using the handrail at the upper end of the folding frame 12, so that the base frame 1 can move using the wheels 11 and the universal wheels 311 at the lower end of the adjusting frame 31, move the device to the planting pit digging position, align the semi-circular cone seat 44 with the planting pit position, and connect the device's electrical equipment to an external generator.

[0079] S2: Control the electric push rod 321 to start retracting, so that the height of the fixed bracket 32 ​​is reduced, which in turn drives the height of the semi-circular collection cylinder 41 to start decreasing, so that the semi-annular cone seat 44 moves downward and is inserted into the soil.

[0080] S3: Then control the digging drive mechanism 53 to work, so that it drives the spiral drill rod 54 to start rotating. At the same time, control the lifting motor 221 to start working, so that the lifting screw 22 starts rotating. Through the threaded connection between the lifting screw 22 and the portal sliding seat 211, the portal sliding seat 211 drives the adjusting seat 21 to start descending. Then, the horizontal adjusting frame 23 drives the digging platform 51 to descend, so that the spiral drill rod 54 moves downward at a constant speed and gradually contacts the ground. The digging work begins by using the rotation of the spiral drill rod 54.

[0081] S4: As the excavation work progresses, the soil generated from the excavation gradually rises with the rotation of the auger rod 54 and rises along the circular cylinder formed by the two sealing plates 42. Then, through the annular opening below the conical cover plate 411, the soil generated from the excavation is thrown into the area below the conical cover plate 411 by the rotation of the auger rod 54. With the shielding and rebound of the conical cover plate 411, the soil enters the semi-circular collection cylinder 41 and the semi-circular sealing plate 42.

[0082] S5: As the digging work is completed and the auger drill rod 54 continues to work for a certain period of time, the soil generated by the digging will be completely put into the semi-circular collection cylinder 41 and the sealing plate 42. Then, the lifting motor 221 is controlled to work in reverse, so that the lifting screw 22 rotates in reverse, thereby causing the adjusting seat 21 to rise. The auger drill rod 54 is moved out of the planting pit by the horizontal adjusting frame 23.

[0083] S6: When the adjusting seat 21 rises to the original position, the lifting motor 221 is stopped and the digging drive mechanism 53 is stopped. At this time, the planting pit is dug.

[0084] S7: At this time, the electric push rod 321 is extended, which pushes the fixed bracket 32 ​​to increase its height, thereby causing the semi-circular collection cylinder 41 to rise, so that the semi-annular cone seat 44 is separated from the ground and rises to a certain height. Then, the adjusting push rod 33 is extended, which pushes the adjusting frame 31 to move to the outer front end of the base frame 1, thereby separating the two semi-circular collection cylinders 41. When the adjusting frame 31 rotates a certain angle, the adjusting push rod 33 stops working.

[0085] S8: Control the horizontal motor 52 to start working, so that it drives the horizontal screw 231 to rotate through the transmission of the bevel gear. Then, through the threaded connection between the horizontal screw 231 and the concave sliding seat 212, the horizontal adjustment frame 23 drives the digging platform 51 to start moving horizontally, so that the spiral drill rod 54 moves to the outside of the cylinder where the two semi-circular collection cylinders 41 are joined. Then control the horizontal motor 52 to stop working.

[0086] S9: Then the staff transplanted the garden trees into the planting pit. After the garden seedlings were placed in the planting pit and fixed, the control adjustment rod 33 was retracted, causing the adjustment frame 31 to move in the opposite direction until the two semi-circular collection cylinders 41 were connected. Then the control adjustment rod 33 stopped working, and then the electric push rod 321 was controlled to start retracting, causing the semi-circular collection cylinder 41 to descend and the semi-circular cone seat 44 to be inserted into the ground.

[0087] S10: At this time, the cylindrical sleeve after the two sealing plates 42 are connected is placed on the tree. The staff can adjust the tree to be vertical according to the positional relationship between the cylinder and the tree. Then, the staff manually lifts the two arc-shaped adjustment plates 43, so that the sealing plates 42 can be adjusted by the adjustment rod 431 to start rising, thereby opening the lower end of the side surface of the semi-circular collection cylinder 41, allowing the soil to be backfilled into the planting pit and burying the tree roots.

[0088] S11: Workers can use methods such as tapping to backfill all the soil into the planting pit, and then control the electric push rod 321 to extend again, so that the semi-circular collection cylinder 41 rises to a certain height. Then, control the adjusting push rod 33 to extend again, so that the adjusting frame 31 drives the two semi-circular collection cylinders 41 to rotate outward at a certain angle. Then, workers can use the moving device to detach it from the tree.

[0089] S12: Then the operator can control the horizontal motor 52 to work in reverse, so that the horizontal screw 231 rotates in reverse, thereby causing the digging platform 51 to move in reverse, so that the auger drill rod 54 moves again to the center position of the cylinder formed by the two sealing plates 42, and then control the horizontal motor 52 to stop working.

[0090] S13: Then the staff controls the adjusting push rod 33 to retract, so that the adjusting frame 31 rotates back to its original position and the two semi-circular collecting cylinders 41 are connected. Then the staff controls the adjusting push rod 33 to stop working.

[0091] When using this device, workers can install spray pipes and spray nozzles on the conical cover plate 411, connect the spray pipes to the external water pipes, and control the spray flow of water from the spray nozzles according to the soil backfilling situation during the soil backfilling process, so that the soil can be backfilled quickly and the soil backfilling is clean. On the other hand, the irrigation of the water flow can make the soil backfilling more compact and avoid soil residue.

[0092] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
