Description

Technical Field

[0001] The invention relates to the field of construction site cleaning, and in particular to a wind power generation foundation pile pit cleaning device. Background Art

[0002] The wind turbine foundation pile foundation pit is an underground space excavated for the installation of wind turbine foundation piles. Its main function is to provide a stable installation position for the foundation piles to ensure that the wind turbine can withstand huge wind loads, deadweight and other dynamic and static loads during operation.

[0003] After the excavation of the foundation pit is completed, it is necessary to cast the base of the wind turbine generator set in the center of the foundation pit. The base is first tied into the shape of a base with steel bars, and then a fence is set on the outside of the steel bars. After that, concrete is poured on the steel bars inside the fence. Before pouring, it is necessary to clean the bottom part of the foundation pit between the outside of the fence and the inside of the side wall of the foundation pit and some loose soil and gravel remaining on the side wall of the foundation pit to prevent these debris from mixing into the interior of the base and affecting the bearing capacity of the foundation piles.

[0004] At present, small excavation equipment or manual cleaning is mainly used to clean the bottom and side walls of the foundation pit. However, this cleaning method requires multiple workers to cooperate with the excavation equipment to clean the side walls and bottom of the foundation pit at the same time, which makes the cleaning efficiency poor. When cleaning and collecting the gravel, a large amount of soil is easily mixed in, resulting in less soil at the bottom of the foundation pit, which in turn affects the stability of the foundation pit. In addition, the existing excavation equipment needs to sequentially excavate, collect, backfill and compact the gravel embedded in the bottom of the foundation pit, which further reduces the efficiency of cleaning the foundation pit.

[0018] The beneficial effects of the present invention are as follows:

[0019] First, the present invention uses a positioning mechanism and a wall-sweeping assembly to position the rectangular frame at the cleaning position of the foundation pit. Subsequently, the crawler vehicle drives the first rotary sweeper through the rectangular frame to sweep the loose soil and gravel at the bottom of the foundation pit. At the same time, the rectangular frame drives the wall-sweeping assembly to sweep the loose soil on the side wall of the foundation pit, so as to realize the simultaneous cleaning of the bottom and side walls of the foundation pit and improve the cleaning efficiency.

[0020] 2. The present invention adopts a No. 1 roller to move the loose soil and gravel to the filter plate, and then separates the loose soil from the gravel through the filter plate, so as to realize the separate collection and treatment of the loose soil and gravel, and then the gravel pit can be backfilled with soil through the pit filling component, thereby realizing rapid backfilling, and after the pit filling component backfills the gravel pit, the foundation pit can also be compacted and leveled, thereby further increasing the cleaning efficiency by performing cleaning, backfilling and leveling simultaneously.

[0021] 3. The present invention adopts a knife driving assembly to drive the tilling blade to automatically dig out the gravel embedded in the bottom of the foundation pit, but will not dig the gravel scattered on the foundation pit, thereby avoiding the tilling blade from excessively turning the foundation pit. While ensuring the compactness of the foundation pit soil, it also avoids the appearance of more loose soil due to turning the soil, thereby ensuring the cleaning effect.

[0022] Fourth, the present invention adopts the method that the No. 2 roller sweep rotates synchronously with the No. 1 roller sweep, so that the No. 2 roller sweep drives the gravel and soil to move backward along the filter plate. At the same time, the No. 2 roller sweep on the rear side drives the filter plate to swing back and forth left and right through the circular plate, thereby increasing the screening effect of the filter plate on soil and gravel.

The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0035] See also Figure 1 and Figure 2 A wind power generation foundation pile pit cleaning device comprises a crawler vehicle 1, a support arm 2 is fixedly installed on the upper part of the crawler vehicle 1, a rectangular frame 3 is set on the lower right part of the support arm 2 for sliding up and down through a guide column, a height hydraulic rod 21 is fixedly installed on the upper part of the support arm 2, the telescopic section of the height hydraulic rod 21 is fixedly connected to the rectangular frame 3, a positioning mechanism 4 for limiting itself is set on the rectangular frame 3, and a cleaning mechanism 5 for cleaning the bottom and side walls of the foundation pit is also set on the rectangular frame 3.

[0036] When the foundation pit needs to be cleaned, the operator first controls the tracked vehicle 1 to move to the edge of the foundation pit, so that the tracked vehicle 1 drives the rectangular frame 3 to move to the upper part of the foundation pit through the support arm 2, so that the rectangular frame 3 is located in the upper part between the side wall and the enclosure, and then extends the telescopic section of the height hydraulic rod 21 to drive the rectangular frame 3 down to the inside of the foundation pit, and the rectangular frame 3 drives the positioning mechanism 4 and the cleaning mechanism 5 to move synchronously to the inside of the foundation pit.

[0037] Then, the rectangular frame 3 is confined to the position of the foundation pit through the cleaning mechanism 5 and the positioning mechanism 4, and the tracked vehicle 1 is started to drive the rectangular frame 3 to move, so that the rectangular frame 3 rotates around the enclosure through the positioning mechanism 4, and at the same time, the rectangular frame 3 drives the cleaning mechanism 5 to clean the bottom and side walls of the foundation pit.

[0038] See also Figure 1 , Figure 2 and Figure 3 The cleaning mechanism 5 includes a stone storage bin 51 which is slidably arranged at the lower part of the rectangular frame 3, a mounting frame 52 is fixedly installed on the front side of the stone storage bin 51, and a No. 1 roller sweeper 53 is rotatably arranged at the middle part of the lower side of the mounting frame 52. The cleaning mechanism 5 also includes a wall sweeping assembly 58 for cleaning the side wall of the foundation pit which is arranged on the left side of the rectangular frame 3. The wall sweeping assembly 58 includes a vertical plate 581 which is slidably arranged on the left side of the rectangular frame 3 through a column, an angle plate 582 is hingedly connected to the lower left part of the vertical plate 581, a spiral roller sweeper 583 is rotatably arranged on the left side of the angle plate 582, and an execution motor 584 is fixedly installed on the upper part of the angle plate 582, and the output shaft of the execution motor 584 is fixedly connected to the spiral roller sweeper 583.

[0039] See also Figure 1 and Figure 2 A second hydraulic rod 587 is fixedly installed on the upper left side of the rectangular frame 3, and the telescopic section of the second hydraulic rod 587 is fixedly connected to the vertical plate 581. A driven plate 585 is rotatably provided on the upper part of the vertical plate 581, and a threaded rod 586 is rotatably provided on the middle part of the right side of the angle plate 582, and the threaded rod 586 is threadedly connected to the driven plate 585.

[0040] When the rectangular frame 3 is located inside the foundation pit, the rectangular frame 3 drives the No. 1 roller 53 to contact the bottom of the foundation pit through the stone storage bin 51 and the mounting frame 52 in turn, and then the operator manually rotates the threaded rod 586, so that the threaded rod 586 drives the angle plate 582 to rotate along the lower part of the vertical plate 581, so that the angle plate 582 is parallel to the side wall of the foundation pit, and then the telescopic section of the No. 2 hydraulic rod 587 is extended to drive the vertical plate 581 to move toward the direction close to the side wall of the foundation pit, so that the vertical plate 581 drives the spiral roller 583 to rest against the side wall of the foundation pit through the angle plate 582.

[0041] Continue reading Figure 1 and Figure 2The positioning mechanism 4 includes a position plate 41 which is set on the right side of the rectangular frame 3 by sliding left and right through a guide rod. A bow plate 42 is fixedly installed on the right side of the position plate 41. Abutment wheels 43 are rotatably set at the lower parts of the front and rear ends of the bow plate 42. A hydraulic rod 44 is fixedly installed on the right side of the upper part of the rectangular frame 3. The telescopic section of the hydraulic rod 44 is fixedly connected to the position plate 41.

[0042] When the spiral roller 583 abuts against the side wall of the foundation pit, the telescopic section of the No. 1 hydraulic rod 44 is extended to drive the position plate 41 to move toward the enclosure, and the position plate 41 drives the two abutment wheels 43 to synchronously abut against the enclosure through the bow plate 42. At this time, the two abutment wheels 43 and the spiral roller 583 are limited to make the rectangular frame 3 arranged radially along the foundation pit, and then the crawler vehicle 1 is moved to rotate along the center of the foundation pit, and the crawler vehicle 1 synchronously drives the rectangular frame 3 to rotate circumferentially along the foundation pit.

[0043] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The cleaning mechanism 5 also includes a soil storage bin 54 fixedly mounted on the lower side of the stone storage bin 51, a filter plate 55 is slidably arranged on the front side of the soil storage bin 54, and the filter plate 55 is arranged to be gradually inclined upward from front to back. The cleaning mechanism 5 also includes a knife driving assembly 59 for controlling the tilling blade 57, and the knife driving assembly 59 includes a rotating tube 591 rotatably arranged on the upper front side of the mounting frame 52, and a plurality of No. 2 roller sweeps 595 arranged along the length direction of the filter plate 55 are rotatably arranged on the rear side of the lower part of the mounting frame 52, and a driving motor 596 is fixedly mounted on the upper part of the mounting frame 52, and a transmission belt is wound around the output shaft of the driving motor 596, the No. 2 roller sweep 595, the No. 1 roller sweep 53 and the rotating tube 591.

[0044] While the rectangular frame 3 rotates along the circumference of the foundation pit, the rectangular frame 3 drives the No. 1 roller 53 to move synchronously, and then the drive motor 596 is started, so that the drive motor 596 drives the No. 2 roller 595, the No. 1 roller 53 and the rotating tube 591 to rotate synchronously, so that the No. 1 roller 53 sweeps the scattered gravel on the foundation pit that is not embedded in the soil to the filter plate 55, and then the No. 2 roller 595 gradually pushes the gravel along the filter plate 55 to the inside of the soil storage bin 54 from front to back. While sweeping the gravel, the No. 1 roller 53 sweeps the loose soil on the bottom of the foundation pit to the filter plate 55, and then the loose soil passes through the sieve holes of the filter plate 55 and falls into the inside of the soil storage bin 54, thereby realizing the separate collection of gravel and loose soil.

[0045] While rotating the first rolling broom 53, start the actuating motor 584 at the same time, so that the actuating motor 584 drives the spiral rolling broom 583 to rotate, thereby enabling the spiral rolling broom 583 to sweep the loose soil and sundries on the side wall of the foundation pit, and the sundries swept down can be pushed downward by the spiral rolling broom 583, preventing the sundries from flying to a certain extent.

[0046] It should be noted that the front side of the bottom of the soil storage bin 54 is in a slope structure that gradually slopes downward from front to back, so that the loose soil falling from the filter plate 55 to the bottom of the soil storage bin 54 can slide backward along the slope on the soil storage bin 54 under the action of gravity, preventing the loose soil from accumulating at the front of the soil storage bin 54.

[0047] Refer to Figure 3 、 Figure 4 and Figure 8 As shown in, a circular plate 5951 is fixedly installed at the right end of the last second rolling broom 595. A wavy track groove 5952 is formed on the cylindrical surface of the circular plate 5951. A fixing rod 5953 is fixedly installed at the position corresponding to the circular plate 5951 on the upper side of the filter plate 55, and the upper end of the fixing rod 5953 is inserted into the inside of the track groove 5952.

[0048] When the second rolling broom 595 rotates, the last second rolling broom 595 drives the circular plate 5951 thereon to rotate synchronously, so that the circular plate 5951 reciprocates the fixing rod 5953 left and right through the track groove 5952 thereon, and the fixing rod 5953 drives the filter plate 55 to reciprocate left and right synchronously, thereby shaking the filter plate 55 left and right, and further increasing the separation effect of the filter plate 55 on the crushed stones and loose soil.

[0049] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 7 As shown in, the cleaning mechanism 5 further includes a cross bar 56 fixedly installed at the lower part of the front side of the mounting frame 52. Plowing knife members 57 are rotatably arranged at equal intervals in the left - right direction on the cross bar 56. The knife driving assembly 59 further includes a horizontal support plate 593 fixedly installed at the lower part of the front side of the rectangular frame 3. An L - shaped plate 594 is fixedly installed on the front side of the horizontal support plate 593. Lifting plates 5971 corresponding to the plowing knife members 57 one by one are arranged at equal intervals in the left - right direction on the horizontal section of the L - shaped plate 594. The lifting plates 5971 are slidably connected to the L - shaped plate 594 up and down through follower columns. A stone shoveling member 5972 is slidably arranged back and forth at the lower part of the lifting plate 5971. The upper part of the stone shoveling member 5972 is in a U - shaped structure, and the lower part of the stone shoveling member 5972 is in an isosceles trapezoid structure.

[0050] Refer to Figure 2 、 Figure 3 and Figure 7, on the transverse section of the L-shaped plate 594, spring telescopic rods 5973 corresponding to the lifting plates 5971 one by one are fixedly installed at equal intervals in the left-right direction. The telescopic section of the spring telescopic rod 5973 is fixedly connected to the lifting plate 5971. A displacement sensor is arranged inside the spring telescopic rod 5973. On the lower part of the transverse section of the L-shaped plate 594, chute members 5974 corresponding to the lifting plates 5971 one by one are fixedly installed at equal intervals in the left-right direction. An elongated waist-shaped groove that slopes upward gradually from front to back is formed in the lower part of the chute member 5974. The chute member 5974 is located on the left side of the stone shoveling member 5972 at the corresponding position. The left side of the U-shaped structure of the stone shoveling member 5972 slides inside the elongated waist-shaped groove of the chute member 5974 through a protruding column.

[0051] During the movement, the rectangular frame 3 drives the stone shoveling member 5972 to move synchronously through the horizontal support plate 593, the L-shaped plate 594, and the lifting plate 5971 in sequence. When the stone shoveling member 5972 contacts the crushed stones scattered on the bottom of the foundation pit, the crushed stones move to the upper side of the isosceles trapezoid structure at the lower part of the stone shoveling member 5972 through the inclined surface of the isosceles trapezoid structure at the lower part of the stone shoveling member 5972, and then the crushed stones pass through the U-shaped structure at the upper part of the stone shoveling member 5972 and move to the rear side of the stone shoveling member 5972, so that the crushed stones scattered on the bottom of the foundation pit will not hinder the movement of the stone shoveling member 5972.

[0052] When the stone shoveling member 5972 contacts the crushed stones embedded in the bottom of the foundation pit, the crushed stones embedded in the bottom of the foundation pit hinder the movement of the stone shoveling member 5972, causing the stone shoveling member 5972 to move backward relative to the lifting plate 5971. At the same time, the stone shoveling member 5972 drives the protruding column thereon to move along the elongated waist-shaped groove of the chute member 5974, so that the stone shoveling member 5972 moves upward while moving backward relative to the lifting plate 5971, thereby enabling the stone shoveling member 5972 to move to the upper part of the crushed stones embedded in the bottom of the foundation pit, and further enabling the stone shoveling member 5972 to cross over the crushed stones embedded in the bottom of the foundation pit.

[0053] Refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 , the knife driving assembly 59 further includes driving sleeves 592 that are rotatably arranged at equal intervals in the left-right direction on the outside of the rotating pipe 591 and correspond to the tilling knife members 57 one by one. The driving sleeves 592 are connected to the tilling knife members 57 at the corresponding positions through belts. Inside the rotating pipe 591, two-way electric push rods 597 corresponding to the driving sleeves 592 one by one are fixedly installed at equal intervals in the left-right direction. Grooves for inserting the telescopic sections of the two-way electric push rods 597 are formed at equal intervals along the circumferential direction on the inner side surface of the driving sleeve 592.

[0054] When the stone-shoveling piece 5972 moves upward, the stone-shoveling piece 5972 compresses the spring telescopic rod 5973 through the lifting plate 5971. At the same time, the displacement sensor on the spring telescopic rod 5973 records the displacement of the telescopic section of the spring telescopic rod 5973. When the displacement of the telescopic section of the spring telescopic rod 5973 reaches the standard, the telescopic section of the bidirectional electric push rod 597 corresponding to the position of the upward stone-shoveling piece 5972 is extended, so that the telescopic section of the bidirectional electric push rod 597 is inserted into the groove of the active sleeve 592 at the corresponding position.

[0055] After the telescopic section of the bidirectional electric push rod 597 extends into the groove of the active sleeve 592 at the corresponding position, the active sleeve 592 at the corresponding position is locked with the rotating tube 591 as a whole, so that the rotating tube 591 drives the active sleeve 592 at the corresponding position to rotate synchronously, and the active sleeve 592 drives the tilling blade piece 57 corresponding to the position of the upward shovel piece 5972 to rotate synchronously, so that the tilling blade piece 57 can dig out the gravel embedded in the bottom of the foundation pit, thereby specifically excavating the soil at the position of the gravel embedded in the bottom of the foundation pit, and will not excavate the soil elsewhere, thereby ensuring the compactness of the soil.

[0056] See also Figure 3 and Figure 5 A push-pull square rod 598 corresponding to the active sleeve 592 is set on the front side of the horizontal support plate 593 to slide up and down at equal intervals along the left and right directions. A return spring is set between the push-pull square rod 598 and the horizontal support plate 593, and an elliptical plate 5981 is sleeved on the outer side of the active sleeve 592 at the position corresponding to the push-pull square rod 598.

[0057] When the active sleeve 592 starts to rotate, the active sleeve 592 drives the elliptical plate 5981 thereon to rotate synchronously, and the return spring pushes the lower end of the pushing square rod 598 to always press against the outer surface of the elliptical plate 5981 through its own elastic force, so that the elliptical plate 5981 intermittently pushes the pushing square rod 598 upward, and when the stone-shoveling piece 5972 passes over the gravel embedded in the bottom of the foundation pit, the spring telescopic rod 5973 drives the stone-shoveling piece 5972 to move downward to the initial height position, and then delays for a period of time to retract the telescopic section of the two-way electric push rod 597 at the corresponding position, so that the tilling blade piece 57 digs out the gravel embedded in the bottom of the foundation pit, and then the active sleeve 592 and the rotating tube 591 are separated from the synchronous rotation, and then the pushing square rod 598 drives the active sleeve 592 to rotate to the initial angle by pushing the elliptical plate 5981, and the active sleeve 592 drives the tilling blade piece 57 to rotate synchronously, so that the tilling blade of the tilling blade piece 57 does not contact the foundation pit ground.

[0058] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9The cleaning mechanism 5 also includes a pit filling component 50 that is jointly arranged on the rectangular frame 3 and the soil storage bin 54. The pit filling component 50 includes a lower soil opening 501 that is evenly spaced along the left and right directions and is opened at the lower side of the soil storage bin 54. The lower soil opening 501 corresponds to the tillage blade 57 one by one. The lower side of the soil storage bin 54 is evenly spaced along the left and right directions and is provided with a shielding plate 502 that is slidably connected to it front and back. The shielding plate 502 corresponds to the lower soil opening 501 one by one. An active electric push rod 503 is fixedly installed on the rear side of the shielding plate 502. The telescopic section of the active electric push rod 503 is fixed to the stone storage bin 51. A support plate 504 is fixedly installed symmetrically on the left and right sides of the rear side of the rectangular frame 3, and a T-shaped tamping plate 505 is set on the rear side of the support plate 504 for sliding up and down together, and two rotating rollers 506 arranged symmetrically up and down are set between the support plates 504 for rotating together, and a chain is wound around the two rotating rollers 506 through a sprocket, and a lifting plate 507 is fixedly installed on the outside of the chain, a raised block 509 is fixedly installed on the right side of the vertical section of the T-shaped tamping plate 505, and a rotating motor 508 connected to one of the rotating rollers 506 is fixedly installed on the left side of the left support plate 504.

[0059] After the tilling blade 57 digs out the gravel embedded in the bottom of the foundation pit, a gravel pit is left at the bottom of the foundation pit. Then, the telescopic section of the active electric push rod 503 corresponding to the position of the tilling blade 57 after rotation is extended with a delay, so that the soil storage bin 54 moves to the upper part of the gravel pit. The active electric push rod 503 drives the closing plate 502 to move, thereby opening the lower soil opening 501 corresponding to the gravel pit, and the soil inside the soil storage bin 54 falls into the gravel pit under the action of gravity, thereby backfilling the gravel pit.

[0060] At the same time, the rotating motor 508 is started, so that the rotating motor 508 drives the rotating roller 506 to rotate, and the rotating roller 506 drives the lifting plate 507 to move through the chain. When the lifting plate 507 rotates to the lower side of the protruding block 509, the lifting plate 507 drives the T-shaped tamping plate 505 to move vertically upward by pushing the protruding block 509. When the lifting plate 507 rotates to the front side of the rotating roller 506, the T-shaped tamping plate 505 falls under the action of gravity, so that the horizontal section of the T-shaped tamping plate 505 tamps on the bottom of the foundation pit, thereby leveling the foundation pit. In order to reduce the resistance of the lifting plate 507 when it rotates, a ball bearing can be set on the surface of the lifting plate 507 that contacts the T-shaped tamping plate 505.

[0061] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A screw rod 31 is rotatably arranged inside the rectangular frame 3, a sliding support plate 511 is fixedly installed on the upper middle side of the stone storage bin 51, the screw rod 31 is inserted into the sliding support plate 511 and is threadedly connected thereto, and a power motor 32 with an output shaft fixedly connected to the screw rod 31 is arranged inside the rectangular frame 3.

[0062] After the rectangular frame 3 rotates around the foundation pit for one circle, the power motor 32 is started to drive the screw rod 31 to rotate. The screw rod 31 drives the stone storage bin 51 to move a certain distance along the length direction of the rectangular frame 3 through the sliding support plate 511, so that the tilling blade 57 and the stone shovel 5972 can detect and remove gravel at positions that have not been passed on the foundation pit, and at the same time, the No. 1 roller 53 can comprehensively clean the foundation pit.

[0063] See also Figure 1-Figure 9 When cleaning the foundation pit, the present invention also includes the following steps:

[0064] In the first step, the operator controls the crawler vehicle 1 to move to the edge of the foundation pit, so that the crawler vehicle 1 drives the rectangular frame 3 to move to the upper part of the foundation pit through the support arm 2, so that the rectangular frame 3 is located in the upper part between the side wall and the enclosure, and then extends the telescopic section of the height hydraulic rod 21 to drive the rectangular frame 3 down to the inside of the foundation pit, so that the No. 1 roller 53 contacts the bottom of the foundation pit.

[0065] In the second step, the operator manually rotates the threaded rod 586 to make the spiral roller 583 parallel to the side wall of the foundation pit, and then extends the telescopic section of the No. 2 hydraulic rod 587 to drive the spiral roller 583 to rest against the side wall of the foundation pit, and then extends the telescopic section of the No. 1 hydraulic rod 44 to make the two abutting wheels 43 rest against the enclosure at the same time, and the mobile crawler vehicle 1 drives the rectangular frame 3 to rotate along the circumference of the foundation pit.

[0066] In the third step, the gravel embedded in the bottom of the foundation pit pushes the stone-shoveling piece 5972, so that the stone-shoveling piece 5972 compresses the spring telescopic rod 5973. When the displacement of the telescopic section of the spring telescopic rod 5973 reaches the standard, the telescopic section of the two-way electric push rod 597 corresponding to the position of the upwardly moved stone-shoveling piece 5972 is extended, so that the tilling blade piece 57 at the corresponding position will dig out the gravel embedded in the bottom of the foundation pit.

[0067] The fourth step is to start the driving motor 596 and the execution motor 584, so that the No. 1 roller 53 sweeps the gravel and loose soil onto the filter plate 55, the loose soil passes through the sieve holes of the filter plate 55 and falls into the soil storage bin 54, the gravel moves to the inside of the stone storage bin 51, and the execution motor 584 drives the spiral roller 583 to sweep the loose soil and debris on the side wall of the foundation pit.

[0068] The fifth step is to extend the telescopic section of the active electric push rod 503 at the position corresponding to the rotated tiller blade 57, so that when the soil storage bin 54 moves to the upper part of the gravel pit, the active electric push rod 503 drives the closing plate 502 to move, thereby opening the lower soil opening 501 corresponding to the gravel pit, and the soil inside the soil storage bin 54 falls into the gravel pit under the action of gravity, thereby backfilling the gravel pit.

[0069] The sixth step is to start the rotating motor 508, so that the lifting plate 507 intermittently drives the T-shaped tamping plate 505 to move upward, so that the T-shaped tamping plate 505 intermittently falls under the action of gravity, and then the horizontal section of the T-shaped tamping plate 505 intermittently tamps the bottom of the foundation pit, thereby leveling the foundation pit.

[0070] In the seventh step, after the rectangular frame 3 rotates around the foundation pit for one circle, the power motor 32 is started to drive the screw rod 31 to rotate. The screw rod 31 drives the stone storage bin 51 to move a certain distance along the length direction of the rectangular frame 3 through the sliding support plate 511, so that the tilling blade 57 and the stone shovel 5972 can detect and remove the gravel at the position that has not passed through the foundation pit, and at the same time, the No. 1 roller 53 can comprehensively clean the foundation pit.

[0071] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
