A ground foundation ramming device for civil engineering and a method of using the same

Abstract

The application relates to the field of civil engineering, in particular to a foundation ramming device for civil engineering and a use method thereof. In existing foundation ramming operation, after the land in a local area is rammed, the remaining foundation ramming area needs to be leveled with the rammed area, so that the operation surface after ramming is convenient for subsequent operation and processing. However, the ground flatness of the local area is usually inconsistent during the foundation ramming process, which causes the land in some areas to be excessively rammed and affects the subsequent use of the foundation. The foundation ramming device for civil engineering and the use method thereof can avoid the subjective deviation of artificial detection by judging the flatness, ensure that the ramming areas all reach the unified ramming standard, prevent excessive ramming in the local ramming area, avoid the crushing of the aggregate or the insufficiency of ramming, and keep the flatness of the ramming area consistent by adopting real-time monitoring of the flatness in the local ramming operation.

Description

Technical Field

[0001] This invention relates to the field of civil engineering, specifically to a foundation compaction device for civil engineering and its usage method. Background Technology

[0002] During road construction or building construction, it is often necessary to compact the road surface to form a relatively dense hard shell layer on the foundation surface, thereby reinforcing the foundation.

[0003] A foundation refers to the soil or rock mass beneath a building that supports its foundation. Soil layers used for building foundations are classified as rock, gravelly soil, sandy soil, silty soil, clayey soil, and artificial fill. Foundations are divided into two categories: natural foundations and artificial foundations (composite foundations). Natural foundations are natural soil layers that do not require human reinforcement. Artificial foundations require human reinforcement.

[0004] The following problems exist in the existing technology that have not been well resolved: In the existing foundation compaction operation, after compacting the land in a local area, it is necessary to make the flatness of the remaining compacted areas consistent with the flattened areas, so that the compacted working surface can be convenient for subsequent operation and processing. However, the foundation compaction process usually leads to unevenness of the ground in local areas, resulting in over-compaction of the land in some areas, which affects the subsequent use of the foundation. Summary of the Invention

[0009] Preferably, a limiting frame is fixedly connected to the top of the compaction frame, and an adjusting frame is slidably connected inside the limiting frame. An adjusting rod is extended on the adjusting frame toward the horizontal measuring plate. Both the adjusting rod and the extending rod have a retaining ball in the annular groove inside the horizontal measuring plate. An adjusting sleeve is rotatably connected to the fixed rod. The adjusting sleeve is telescopic. An adjusting chuck is fixedly connected to the telescopic end of the adjusting sleeve. A retaining groove is formed on the outer wall of the adjusting chuck. A retaining plate is rotatably connected to the adjusting frame toward the retaining groove, and the retaining plate is rotatably connected to the retaining groove.

[0010] Preferably, the top of the fixed rod is rotatably connected to a movable sleeve column. The outer wall of the movable sleeve column is provided with two corresponding guide grooves. The guide grooves are composed of vertical straight grooves and inclined transition grooves to realize the switching of the motion trajectory from axial to oblique. The tops of the two support rods are fixedly connected to support frames. Limiting wheels are provided on the two support frames, respectively extending into the corresponding guide grooves on the movable sleeve column.

[0011] Preferably, a spline groove is provided on the outer wall of the movable sleeve column, and the adjusting chuck and the movable sleeve column form a rotating joint and a sliding joint. A chuck plate corresponding to the spline groove is provided on the inner wall of the adjusting chuck. When the chuck plate and the spline groove are engaged, the adjusting chuck can rotate with the rotation of the movable sleeve column. An adjusting gear is rotatably connected to the outer wall of the adjusting sleeve column. A rotating rod is rotatably connected to the top of the compaction frame. A first gear and a second gear are connected to the upper shaft of the rotating rod. A one-way shaft is provided inside the first gear, and the first gear meshes with the adjusting gear.

[0012] Preferably, the top surface of the support base is also provided with a feeding assembly, the feeding assembly includes a storage box fixedly connected to the top of the support base, the top of the storage box has a feeding port, the storage box is provided with a screw feeder, the bottom of the storage box has a discharge port, the discharge port is connected with a corrugated pipe, and the corrugated pipe is connected to the compaction frame.

[0013] Preferably, the method of using the foundation compaction device for civil engineering includes the following steps:

[0014] S1: The drive motor drives one of the eccentric turntables to rotate, the lower pressure frame moves eccentrically between the eccentric turntables, the lower pressure plate moves back and forth up and down on the support frame, and the compaction frame moves down synchronously with the lower pressure plate. The compaction plate presses down and contacts the ground of the area to be compacted.

[0015] S2: When the horizontal measuring disc is on the positioning rod, it is in a horizontal state. At this time, the horizontal measuring disc is the initial horizontal value of the soil under the compaction state. When the soil is higher than the initial horizontal value of the ground, during the process of the compaction frame moving down, the compaction frame drives the compaction disc to move down, and the compaction disc will squeeze the ground in the compaction area. At this time, the compaction disc will cause the installation rod and the compaction frame to move relative to each other under the action of the connecting spring.

[0016] S3: The mounting rod drives the extension rod to move the ball in the annular groove of the horizontal measuring plate. The deflection of the horizontal measuring plate will cause the corresponding adjustment rod to deflect through the annular groove. The adjustment rod will drive the adjustment frame to slide downward on the limit frame. The longitudinal movement distance of the adjustment chuck is adjusted by the position and angle of the horizontal measuring plate on the positioning rod.

[0017] S4: As the soil in the compaction area is gradually compacted and reaches the level of the flat ground, the compaction frame moves down, causing the fixed rod to move the rotating movable sleeve down synchronously. The limit wheels on the two support frames are in the vertical grooves in the guide slide. When the compaction frame moves to the bottom, the inclined transition groove will cause the movable sleeve to rotate clockwise under the restriction of the limit wheels. At the same time, the adjusting chuck will slide on the outer wall of the movable sleeve. The locking plate will make the adjusting chuck located in the spline groove on the outer wall of the movable sleeve. The adjusting chuck and the movable sleeve are then connected.

[0018] S5: When the moving sleeve moves down and rotates under the restriction of the limit wheel, it will drive the adjusting chuck to rotate. The adjusting chuck will drive the adjusting gear to rotate clockwise. The adjusting gear will drive the first gear to rotate counterclockwise. The first gear will drive the rotating rod to rotate the second gear counterclockwise. Under the restriction of the limit rack, the second gear will cause the compaction frame to move away from the lower pressure frame. The compaction plate at the bottom of the compaction frame will move towards the next compaction area.

[0019] S6: The material to be filled is discharged through the discharge port by the screw feeder in the storage box. The discharge port is connected to the corrugated pipe, which is located on the compaction frame, so that the material to be filled is in the compacted area.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In this invention, when the horizontal position of the horizontal measuring disc changes, the longitudinal movement distance of the chuck can be adjusted by adjusting the position angle of the horizontal measuring disc on the positioning rod. When the land is compacted, the flatness of the ground during the compaction process is monitored by the horizontal measuring disc, and it is observed whether the surface flatness of the compacted area is consistent with that of the flat ground.

[0022] In this invention, real-time monitoring can quickly detect local depressions or bulges, enabling timely compaction or repair, thus avoiding problems such as hollowing and cracking during paving and pouring due to insufficient ground flatness. Furthermore, real-time monitoring data via a level measuring plate allows for targeted compaction, avoiding blind and repetitive work.

[0023] In this invention, when the flatness of the compaction area below the compaction disc is consistent with the initial flatness, the compaction disc can no longer contact the compaction area. By judging the flatness, the subjective bias of manual inspection can be avoided, ensuring that the compaction area meets the uniform compaction standard. Moreover, after recognizing that the flatness meets the standard, the working surface can be moved in time to prevent over-compaction in local compaction areas, avoiding aggregate breakage or insufficient compaction. In local compaction operations, the use of real-time monitoring of flatness can more effectively keep the flatness of the compaction area consistent. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 12The present invention provides a technical solution: a foundation compaction device for civil engineering, including a support frame 1, a drive motor 11 fixedly connected to the outer wall of the support frame 1, the main shaft of the drive motor 11 being rotatably connected to the support frame 1, a compaction component 2 being slidably connected to the main shaft of the drive motor 11, the compaction component 2 being slidably connected to the support frame 1, and a horizontal monitoring component 3 for judging the flatness of the roadbed in a local area being provided on the compaction component 2, the horizontal monitoring component 3 being drivenly connected to the compaction component 2.

[0039] In this embodiment, the compaction component 2 includes two eccentric turntables 21, which are rotatably mounted on the inner wall of the support frame 1. The main shaft of one of the eccentric turntables 21 is connected to the main shaft of the drive motor 11. A lower pressure frame 22 is eccentrically connected between the two eccentric turntables 21. A lower pressure plate 23 is slidably connected to the side wall of the support frame 1. The lower pressure frame 22 and the lower pressure plate 23 are hinged together.

[0040] Telescopic rods 24 are fixedly connected to the inner sidewall of the lower pressure plate 23. The telescopic ends of the two telescopic rods 24 are fixedly connected to a compaction frame 25. A receiving cavity 26 is opened inside the compaction frame 25. An installation rod 27 is slidably connected inside the receiving cavity 26. A compaction disc 28 is fixedly connected to the bottom of the installation rod 27. A connecting spring 29 is sleeved on the installation rod 27. The two ends of the connecting spring 29 are respectively connected to the installation rod 27 and the inner wall of the receiving cavity 26. A support seat 210 is also fixedly connected to the inner wall of the bearing frame 1. A support plate 211 is slidably connected to the support seat 210. A support rod 212 is fixedly connected to the support plate 211. The compaction frame 25 is slidably connected to the two support rods 212.

[0041] When compacting the roadbed, the support frame 1 is set up above the ground to be compacted. The drive motor 11 drives one of the eccentric turntables 21 to rotate. The pressure frame 22, which is located between the two eccentric turntables 21, will move eccentrically between the two eccentric turntables 21. The other end of the pressure frame 22 is connected to the pressure plate 23. At this time, the pressure plate 23 will move up and down on the support frame 1. The compaction frame 25 is connected to the pressure plate 23 through the telescopic rod 24 and will move down synchronously with the pressure plate 23. The mounting rod 27 inside the compaction frame 25 will drive the compaction plate 28 to press down. The compaction plate 28 presses down and contacts the ground of the area of ​​the roadbed to be compacted, thereby compacting the area.

[0042] In this embodiment, the horizontal monitoring component 3 includes a fixed rod 31 fixedly connected to the top of the compaction frame 25. A positioning rod 32 is provided on the fixed rod 31 perpendicular to its axis. A horizontal measuring disk 33 is rotatably connected to the positioning rod 32. An annular groove 34 is provided on the outer wall of the horizontal measuring disk 33. An extension rod 35 is fixedly connected to the mounting rod 27 in the direction of the horizontal measuring disk 33. An extension plate 36 is fixedly provided on the extension rod 35, and the extension plate 36 is slidably connected to the outer wall of the compaction frame 25.

[0043] The top of the compaction frame 25 is also fixedly connected to a limiting frame 37. An adjusting frame 38 is slidably connected inside the limiting frame 37. An adjusting rod 39 is extended on the adjusting frame 38 toward the horizontal measuring disk 33. Both the adjusting rod 39 and the extending rod 35 have a retaining ball 310 in the annular groove 34 inside the horizontal measuring disk 33. An adjusting sleeve 311 is rotatably connected to the fixing rod 31. The adjusting sleeve 311 is telescopic. An adjusting chuck 312 is fixedly connected to the telescopic end of the adjusting sleeve 311. A retaining groove 313 is opened on the outer wall of the adjusting chuck 312. A retaining plate 314 is rotatably connected to the adjusting frame 38 toward the retaining groove 313, and the retaining plate 314 is rotatably connected to the retaining groove 313.

[0044] When compacting the roadbed, after compacting the roadbed in a local area, the compaction plate 28 is on the upper surface of the compacted ground and will not compact the ground further. Since the compaction plate 28 is not in contact with the ground surface, the installation rod 27 will not drive the extension rod 35 to move the ball 310. At this time, the horizontal measuring plate 33 is in a horizontal state on the positioning rod 32. The horizontal measuring plate 33 is at the initial horizontal value of the land under compaction state.

[0045] When compacting the land in the compaction area, if the land is higher than the initial level of the ground, during the downward movement of the compaction frame 25, the compaction frame 25 will drive the compaction plate 28 to move downward. The compaction plate 28 will then squeeze the ground in the compaction area. At this time, the compaction plate 28 will cause the mounting rod 27 to move relative to the compaction frame 25 under the action of the connecting spring 29.

[0046] When relative displacement occurs between the mounting rod 27 and the compaction frame 25, the mounting rod 27 will drive the extension rod 35 to move the ball 310 within the annular groove 34 of the horizontal measuring plate 33, thereby causing the horizontal measuring plate 33 to deflect. The deflection of the horizontal measuring plate 33 will cause the adjusting rod 39, which is positioned opposite to it, to deflect through the annular groove 34. The adjusting rod 39 will then drive the adjusting frame 38 to slide downward on the limiting frame 37. During the sliding process of the adjusting frame 38, the adjusting chuck 312 will extend and retract on the adjusting sleeve 311 through the locking plate 314, thus changing the horizontal position of the horizontal measuring plate 33. During the process, the horizontal measuring disc 33 can be used to adjust the position and angle of the chuck 312 on the positioning rod 32 to adjust the longitudinal movement distance. When the land is being compacted, the horizontal measuring disc 33 can be used to monitor the flatness of the ground during the compaction process. It can be observed whether the surface flatness of the compacted area is consistent with that of the flat ground. Real-time monitoring can quickly detect local depressions or bulges, and timely compaction or repair can be carried out to avoid problems such as hollowness and cracking during paving and pouring due to insufficient ground flatness. Furthermore, the horizontal measuring disc 33 can monitor data in real time and compact the ground in a targeted manner to avoid blindly repeating the work.

[0047] In this embodiment, the top of the fixed rod 31 is also rotatably connected to a movable sleeve 4. The outer wall of the movable sleeve 4 is provided with two corresponding guide grooves 41. The guide grooves 41 are composed of a vertical straight groove 42 and an inclined transition groove 43, which realizes the switching of the motion trajectory from axial to oblique. The tops of the two support rods 212 are fixedly connected to support frames 45. Limiting wheels 46 are respectively provided on the two support frames 45 extending into the corresponding guide grooves 41 on the movable sleeve 4.

[0048] The outer wall of the movable sleeve column 4 is also provided with a spline groove 44. The adjusting chuck 312 and the movable sleeve column 4 form a rotating pair and a sliding pair. The inner wall of the adjusting chuck 312 is provided with a chuck plate 47 corresponding to the spline groove 44. When the chuck plate 47 and the spline groove 44 are engaged, the adjusting chuck 312 can rotate with the rotation of the movable sleeve column 4. The outer wall of the adjusting sleeve column 311 is also rotatably connected with an adjusting gear 48. The top of the compaction frame 25 is rotatably connected with a rotating rod 49. The rotating rod 49 is shaft-connected with a first gear 491 and a second gear 492. The first gear 491 is provided with a one-way shaft and meshes with the adjusting gear 48. The top of the lower pressure plate 23 is fixedly connected with a limiting rack 493, which meshes with the second gear 492.

[0049] During the compaction operation of the land in the compaction area, the compaction frame 25 moves downward on the two support rods 212. As the compaction frame 25 moves downward, it drives the fixed rod 31 to move the rotating movable sleeve 4 downward synchronously. At this time, the limiting wheels 46 on the two support frames 45 are in the vertical straight grooves 42 in the guide slide 41. When the compaction frame 25 moves to the bottom, the inclined transition groove 43 will cause the movable sleeve 4 to rotate clockwise under the restriction of the limiting wheels 46. If the flatness of the ground is inconsistent with that of the level ground during the compaction process, the horizontal measuring plate 33 will be in an inclined state. Simultaneously, the adjusting chuck 312 slides on the outer wall of the movable sleeve 4. The locking plate 47 inside the adjusting chuck 312 does not engage with the spline groove 44 on the outer wall of the movable sleeve 4. At this time, the rotation of the movable sleeve 4 does not cause the adjusting chuck 312 to rotate. When the soil in the compaction area is gradually compacted and reaches the level of flatness, the compaction frame 25 is located on the ground surface. During the downward movement of the compaction frame 25, the level measuring plate 33 is in a horizontal state. The adjusting frame 38 uses the locking plate 314 to position the adjusting chuck 312 in the spline groove 44 on the outer wall of the movable sleeve 4. The adjusting chuck 312 and the movable sleeve 4 are engaged at this time. When the movable sleeve 4 moves down and rotates under the restriction of the limiting wheel 46, it will drive the adjusting chuck 312 to rotate. The adjusting chuck 312 drives the adjusting gear 48 to rotate clockwise. The adjusting gear 48 drives the first gear 491 to rotate counterclockwise. The first gear 491 drives the rotating rod 49 to rotate the second gear 492 counterclockwise. Under the restriction of the limiting rack 493, the second gear 492 will cause the compaction frame 25 to move away from the lower pressure frame 22. The telescopic rod 24 set on the lower pressure frame 22 assists in the limiting. At this time, the compaction frame The tamping disc 28 at the bottom of 25 will move towards the next tamping area. When the flatness of the tamping area below the tamping disc 28 is consistent with the initial flatness, the tamping disc 28 will no longer be in contact with the tamping area. By judging the flatness, the subjective bias of manual inspection can be avoided, ensuring that the tamping area meets the uniform tamping standard. Moreover, after recognizing that the flatness meets the standard, the working surface can be moved in time to prevent over-tamping in local tamping areas, avoiding aggregate breakage or insufficient tamping. Real-time monitoring of flatness in local tamping operations can more effectively keep the flatness of the tamping area consistent.

[0050] In this embodiment, a feeding assembly 5 is also provided on the top surface of the support base 210. The feeding assembly 5 includes a storage box 51 fixedly connected to the top of the support base 210. The top of the storage box 51 is provided with a feeding port 52. A screw feeder 53 is provided inside the storage box 51. A discharge port is provided at the bottom of the storage box 51. A corrugated pipe 54 is connected to the discharge port, and the corrugated pipe 54 is connected to the compaction frame 25.

[0051] When compacting the land within the compaction area, if the bottom of the compaction disc 28 is not in contact with the surface of the area to be compacted, the material to be filled is discharged through the discharge port by the screw feeder 53 in the storage box 51. The discharge port is connected to the corrugated pipe 54, which is located on the compaction frame 25, thereby placing the material to be filled in the compacted area, which facilitates the filling of the material in the depression area.

[0052] The method of use and advantages of this invention: The working process of this foundation compaction device for civil engineering is as follows:

[0053] like Figures 1 to 12 As shown:

[0054] S1: Drive motor 11 drives one of the eccentric turntables 21 to rotate, the lower pressure frame 22 moves eccentrically between the eccentric turntables 21, the lower pressure plate 23 moves back and forth up and down on the support frame 1, the compaction frame 25 moves down synchronously with the lower pressure plate 23, and the compaction plate 28 presses down and contacts the ground of the area to be compacted.

[0055] S2: The horizontal measuring plate 33 is in a horizontal state on the positioning rod 32. The horizontal measuring plate 33 is the initial horizontal value of the soil under the compaction state. When the soil is higher than the initial horizontal value of the ground, during the downward movement of the compaction frame 25, the compaction frame 25 drives the compaction plate 28 to move downward. The compaction plate 28 will squeeze the ground of the compaction area. At this time, the compaction plate 28 will cause the installation rod 27 and the compaction frame 25 to be relatively displaced under the action of the connecting spring 29.

[0056] S3: The mounting rod 27 drives the extension rod 35 to move the ball 310 within the annular groove 34 in the horizontal measuring plate 33. The deflection of the horizontal measuring plate 33 will cause the corresponding adjusting rod 39 to deflect through the annular groove 34. The adjusting rod 39 will drive the adjusting frame 38 to slide downward on the limiting frame 37. The longitudinal movement distance of the adjusting chuck 312 is adjusted by the position and angle of the horizontal measuring plate 33 on the positioning rod 32.

[0057] S4: As the soil in the compaction area is gradually compacted and reaches the level of the flat ground, the compaction frame 25 moves down, driving the fixed rod 31 to move the rotating movable sleeve 4 down synchronously. The limiting wheels 46 on the two support frames 45 are in the vertical straight groove 42 in the guide slide 41. When the compaction frame 25 moves to the bottom, the inclined transition groove 43 will cause the movable sleeve 4 to rotate clockwise under the restriction of the limiting wheel 46. At the same time, the adjusting chuck 312 will slide on the outer wall of the movable sleeve 4. The locking plate 314 makes the adjusting chuck 312 located in the spline slot 44 on the outer wall of the movable sleeve 4. The adjusting chuck 312 and the movable sleeve 4 are connected at this time.

[0058] S5: When the movable sleeve column 4 moves down and rotates under the restriction of the limit wheel 46, it will drive the adjusting chuck 312 to rotate. The adjusting chuck 312 will drive the adjusting gear 48 to rotate clockwise. The adjusting gear 48 will drive the first gear 491 to rotate counterclockwise. The first gear 491 will drive the rotating rod 49 to rotate the second gear 492 counterclockwise. Under the restriction of the limit rack 493, the second gear 492 will cause the compaction frame 25 to move away from the lower pressure frame 22. The compaction plate 28 at the bottom of the compaction frame 25 will move towards the next compaction area.

[0059] S6: The material to be filled is discharged through the discharge port by the screw feeder 53 in the storage box 51. The discharge port is connected to the corrugated pipe 54, which is located on the compaction frame 25, so that the material to be filled is in the compacted area.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.

5. A method of using a foundation compaction device for civil engineering, comprising using the foundation compaction device for civil engineering as described in any one of claims 1-4, characterized in that, Includes the following steps: S1: The drive motor (11) drives one of the eccentric turntables (21) to rotate, the lower pressure frame (22) moves eccentrically between the eccentric turntables (21), the lower pressure plate (23) moves back and forth up and down on the support frame (1), the compaction frame (25) moves down synchronously with the lower pressure plate (23), and the compaction plate (28) presses down and contacts the ground of the area to be compacted; S2: The horizontal measuring plate (33) is in a horizontal state on the positioning rod (32). The horizontal measuring plate (33) is the initial horizontal value of the soil under compaction. When the soil is higher than the initial horizontal value of the ground, the compaction frame (25) moves down and the compaction plate (28) moves down. The compaction plate (28) will squeeze the ground of the compaction area. At this time, the compaction plate (28) will cause the installation rod (27) and the compaction frame (25) to move relative to each other under the action of the connecting spring (29). S3: The mounting rod (27) drives the extension rod (35) to make the ball (310) move in the annular groove (34) in the horizontal measuring plate (33). The deflection of the horizontal measuring plate (33) will cause the corresponding adjustment rod (39) to deflect through the annular groove (34). The adjustment rod (39) will then drive the adjustment frame (38) to slide downward on the limit frame (37). The longitudinal movement distance of the adjustment chuck (312) is adjusted by the position angle of the horizontal measuring plate (33) on the positioning rod (32). S4: When the land in the compaction area is gradually compacted and reaches the flatness range of the flat ground, the compaction frame (25) moves down and drives the fixed rod (31) to move the rotating movable sleeve (4) down synchronously. The limit wheels (46) on the two support frames (45) are in the vertical straight groove (42) in the guide slide (41). When the compaction frame (25) moves to the bottom, the inclined transition groove (43) will cause the movable sleeve (4) to rotate clockwise under the restriction of the limit wheel (46) during the downward movement of the movable sleeve (4). At the same time, the adjusting chuck (312) will slide on the outer wall of the movable sleeve (4). The snap plate (314) makes the adjusting chuck (312) located in the spline slot (44) on the outer wall of the movable sleeve (4). The adjusting chuck (312) and the movable sleeve (4) are connected at this time. S5: When the moving sleeve (4) moves down and rotates under the restriction of the limiting wheel (46), it will drive the adjusting chuck (312) to rotate. The adjusting chuck (312) will drive the adjusting gear (48) to rotate clockwise. The adjusting gear (48) will drive the first gear (491) to rotate counterclockwise. The first gear (491) will drive the rotating rod (49) to make the second gear (492) rotate counterclockwise. Under the restriction of the limiting rack (493), the second gear (492) will cause the compaction frame (25) to move away from the lower pressing frame (22). The compaction plate (28) at the bottom of the compaction frame (25) will move towards the next compaction area. S6: The material to be filled is discharged through the discharge port by the screw feeder (53) in the storage box (51). The discharge port is connected to the corrugated pipe (54), which is located on the compaction frame (25), so that the material to be filled is in the compacted area.
