[0044] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0045] Example 1. This embodiment aims to provide a tool and method for backfilling a deep foundation pit fertilizer trough. It is mainly used for vibrating and compacting the poured foundation pit fertilizer trough after the fluidized solidified soil is poured into the foundation pit fertilizer trough. At present, since the distance between the vibrating rods cannot be adjusted, it takes a long time to vibrate and compact the concrete at the same position, which reduces the vibration effect. In this embodiment, the spacing between the vibrating components can be adjusted by extending the scissor-type telescopic frame 401, so that the vibration effect of the vibrating components can be improved.

[0046] Based on the above problems, Figure 3 and Figure 9 As shown, the mounting frame assembly includes a mounting frame 1 and a swing frame 2 fixed on the mounting frame 1.

[0047] A plurality of mounting frames 1 are spliced ​​together to form a bearing structure, and the bearing structure is used to place the conveying pipeline 6 .

[0048] The movable plate 3 and the gap adjustment mechanism are both arranged on the swing frame 2 , and the movable plate 3 is used to connect with the gap adjustment mechanism and the vibrating mechanism 5 .

[0049] Specifically, the gap adjustment mechanism includes a scissor-type telescopic frame 401 that is movable and suspended on the mounting frame assembly and a drive device assembly 402 that is fixed on the sidemost movable plate 3. In this embodiment, the drive device assembly 402 includes a third drive self-locking motor and a fourth drive self-locking motor. The output end of the third drive self-locking motor is transmission-connected to the rear vertical rod 4012 on the sidemost side, so that the rear vertical rod 4012 moves to extend the scissor-type telescopic frame 401. The lower end of the scissor-type telescopic frame 401 is connected to the movable plate 3. The output end of the drive device assembly 402 is transmission-connected to the scissor-type telescopic frame 401, so that multiple movable plates 3 are evenly extended and retracted along the mounting frame assembly.

[0050] In this embodiment, the transmission method between the third drive self-locking motor and the rear vertical rod 4012 on the most side is that a drive block 7 is provided slidingly in the most side limiting slide groove, and the upper end of the drive block 7 is rotationally connected to the corresponding rear vertical rod 4012. When the drive block 7 moves, it can drive the corresponding rear vertical rod 4012 to move, so that the scissor-type telescopic frame 401 is extended. The output end of the third drive self-locking motor is transmission-connected with a transmission screw 8 extending along the front and rear directions. When the third drive self-locking motor is started, it can drive the transmission screw 8 to rotate. Since the transmission screw 8 is threadedly connected to the drive block 7, it can drive the drive block 7 to move along the limiting slide groove. The drive block 7 is mounted on the transmission screw 8 and is threadedly connected to the transmission screw 8.

[0051] The scissor-type telescopic frame 401 includes a front vertical rod 4011, a rear vertical rod 4012 and a cross-link assembly 4013. The cross-link assembly 4013 is hingedly connected between the two front vertical rods 4011 and the two rear vertical rods 4012. The front vertical rod 4011, the rear vertical rod 4012 and the cross-link assembly 4013 cooperate with each other to enable multiple movable plates 3 to move evenly.

[0052] The connection method of the scissor-type telescopic frame 401 and the swing frame 2 is as follows: Figure 7 As shown, an elongated limiting groove 22 and a rectangular limiting groove 21 are provided on the inner bottom wall of the swing frame 2, and the cross-sectional shapes of the elongated limiting groove 22 and the rectangular limiting groove 21 are both concave limiting structures. In this embodiment, by connecting the front vertical rod 4011 and the rear vertical rod 4012 with the elongated limiting groove 22 and the rectangular limiting groove 21, the scissor-type telescopic frame 401 can be movably suspended on the swing frame 2 to improve stability. The upper end of the front vertical rod 4011 is rotated and provided with a first limiting block, which is slidably arranged in the elongated limiting groove 22 to play a role of limiting sliding on the front vertical rod 4011, and a plurality of sliding plates are slidably provided in the rectangular limiting groove 21, and the sliding plate is provided with a slave limiting groove extending along the extension direction of the limiting groove. The rear vertical rod 4012 is slidably arranged in the corresponding slave limiting groove, so that the rear vertical rod 4012 can play a role of limiting sliding, so that the rear vertical rod 4012 can be easily moved.

[0053] like Figure 9 As shown, after the spacing of the scissor-type telescopic frame 401 is adjusted, the fourth self-locking motor can be used to drive the vibrating assembly to rotate, so that the fluidized solidified soil after pouring is vibrated to achieve a compacting effect.

[0054] Specifically, the vibration mechanism 5 includes a spline shaft 501 and a vibration assembly; the spline shaft 501 is rotatably arranged on the movable plate 3, and the spline shaft 501 passes through the movable plate 3 and is transmission-connected to the output end of the fourth drive self-locking motor through the bevel gear set 9. In this embodiment, the bevel gear set 9 includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly sleeved on the spline shaft 501, and the second bevel gear is transmission-connected to the fourth drive self-locking motor. Since the first bevel gear and the second bevel gear are engaged with each other, the spline shaft 501 can be driven to rotate. A rotating plate 10 is fixedly sleeved on the spline shaft 501, and when the spline shaft 501 rotates, it can drive the rotating plate 10 to rotate.

[0055] The vibration assembly includes a fixed vertical rod 14 and a stirring rod 15. In this embodiment, a vibrator is fixedly provided at the bottom of the long plate 16, and the output end of the vibrator is transmission-connected to the fixed vertical rod 14. The vibrator can drive the fixed vertical rod 14 to vibrate to achieve the vibration effect. The bottom of the rotating plate 10 is fixedly provided with a long plate 16, and the fixed vertical rod 14 is arranged at the bottom of the long plate 16. The stirring rod 15 is fixed on the outer surface of the fixed vertical rod 14. When the rotating plate 10 rotates, it can drive the long plate 16 to rotate, and when the long plate 16 rotates, it can drive the fixed vertical rod 14 to rotate, and the fixed vertical rod 14 then drives the stirring rod 15 to rotate, so that the fluidized solidified soil is compacted.

[0056] In Example 2, in the structure of Example 1, the vibrating assembly can only vibrate and compact the same height, resulting in poor vibration effect.

[0057] Based on the above problems, this embodiment Figure 2 、 Figure 5 and Figure 6 As shown, the vibrating mechanism 5 can be used to vibrate the fluidized solidified soil poured into the foundation pit fertilizer trough at different heights to improve the vibration effect.

[0058] Specifically, the vibrating mechanism 5 includes a spline shaft 501, a lifting screw 502 and a vibrating assembly. The spline shaft 501 and the lifting screw 502 are rotatably arranged on the movable plate 3. The spline shaft 501 passes through the movable plate 3 and is connected to the output end of the fourth drive self-locking motor through the bevel gear set 9. In this embodiment, the bevel gear set 9 includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly sleeved on the spline shaft 501, and the second bevel gear is connected to the fourth drive self-locking motor. A rotating plate 10 is slidingly sleeved on the spline shaft 501. When the spline When the shaft 501 rotates, it can drive the rotating plate 10 to rotate. The lifting plate 11 is sleeved on the lifting screw 502 and is threadedly connected to the lifting plate 11. The lifting plate 11 is rotatably sleeved on the outside of the rotating plate 10. The vibrating assembly is fixed on the rotating plate 10. When the lifting screw 502 rotates, it can drive the lifting plate 11 to rotate. Since the lifting plate 11 is rotatably sleeved on the outside of the rotating plate 10, it can drive the rotating plate 10 to move up and down together, so that the vibrating assembly can move up and down while also rotating, thereby improving the vibration effect.

[0059] A first sprocket 12 is provided on the fixed sleeve of the spline shaft 501, and a second sprocket 13 is provided on the fixed sleeve of the lifting screw 502. The first sprocket 12 and the second sprocket 13 are connected by a chain transmission. When the spline shaft 501 rotates, the lifting screw 502 can be driven to rotate through the first sprocket 12 and the second sprocket 13.

[0060] A primary sprocket 17 is fixed on the spline shaft 501, and the sidemost spline shaft 501 rotates under the action of the fourth drive self-locking motor, and then is transmitted through the second chain, so that multiple spline shafts 501 rotate. A spring 18 extending in the front-to-back direction is fixed on the movable plate 3, and a tensioning frame 19 is fixed on the other end of the spring 18. A secondary sprocket 20 is rotated in the tensioning frame 19, and the primary sprocket 17 and the secondary sprocket 20 are connected by the second chain transmission, so that multiple spline shafts 501 can be driven to rotate. The setting of the secondary sprocket 20 enables the scissors-type telescopic frame 401 to keep the second chain in a taut state at all times through the spring 18 when it is retracted, so as to achieve the result that the scissors-type telescopic frame 401 does not affect the movement of the vibrating assembly when it is adjusted indirectly.

[0061] Compared with Example 1, the advantage of this embodiment is that the vibrating assembly can not only rotate on its own to achieve vibration of the fluidized solidified soil after pouring, but also can vibrate at different depths to improve the vibration effect.

[0062] In Example 3, the swing frame 2 in the structures of Example 1 and Example 2 cannot be adjusted in angle, so that the angle of the swing frame 2 cannot be adjusted according to demand, which reduces practicality.

[0063] Based on the above problems, this embodiment Figure 1 and Figure 8 As shown, the mounting frame assembly includes a mounting frame 1, a second driving device fixed on the mounting frame 1, and a swinging frame 2 that is transmission-connected to the output end of the second driving device; in this embodiment, the second driving device is a second driving self-locking motor, the movable plate 3 is slidingly arranged on the swinging frame 2, and the front vertical rod 4011 and the rear vertical rod 4012 are both slidingly arranged on the swinging frame 2. When the second driving self-locking motor is started, it can drive the swinging frame 2 to rotate to a state parallel to the foundation pit fertilizer trough, so that the vibration assembly can vibrate better.

[0064] Compared with Example 1 and Example 2, the advantage of this embodiment is that the angle of the swing frame 2 can be adjusted according to needs, so that it is suitable for different foundation pit fertilizer troughs to improve practicality.

[0065] A method for using a tool for backfilling a deep foundation pit fertilizer trough is characterized by the following specific operations:

[0066] S1, extend the mounting frame 1 carrying the conveying pipe 6 to the top of the foundation pit fertilizer tank, and connect the mounting frame 1 to form a bearing structure, so that it not only provides a foundation for the installation of the intermittent adjustment mechanism, but also supports the conveying pipe 6;

[0067] S2, driving the second driving device to start, so that the output end of the second driving device drives the swing frame 2 to rotate, and stops when it turns parallel to the foundation pit fertilizer tank, and adjusts the angle of the swing frame 2 according to needs so that the vibrating assembly can better vibrate;

[0068] S3, the driving device assembly 402 is started, so that one of the output ends of the driving device assembly 402 can drive the transmission screw 8 to rotate, causing the driving block 7 to slide along the limiting slide groove, and driving one of the rear vertical rods 4012 to move along the extension direction of the limiting slide groove, causing the cross-link assembly 4013 to rotate, so as to adjust the spacing between adjacent movable plates 3;

[0069] S4, after the spacing is adjusted, the other output terminal of the driving device assembly 402 is driven forward and reversely, so that the spline shaft 501 is driven to rotate. When the spline shaft 501 rotates, the rotating plate 10 is driven to rotate, so that the vibrating assembly is driven to stir and vibrate the fluidized solidified soil poured into the foundation pit fertilizer tank;

[0070] S5, when the spline shaft 501 rotates, it can drive the lifting screw 502 to rotate through the first sprocket 12 and the second sprocket 13, so that the lifting screw 502 drives the lifting plate 11 to move up and down, and in the process of moving up and down, it drives the rotating plate 10 to move up and down along the spline shaft 501, so that the vibrating assembly can be lifted and lowered while rotating. When the spline shaft 501 rotates, it can drive the rotating plate 10 to rotate. When the rotating plate 10 rotates, it can drive the long plate 16 to rotate. When the long plate 16 rotates, it can drive the fixed vertical rod 14 to rotate, and the fixed vertical rod 14 then drives the stirring rod 15 to rotate, so that the fluidized solidified soil is compacted. When the lifting screw 502 rotates, it can drive the lifting plate 11 to rotate. Since the lifting plate 11 is rotated and sleeved on the outside of the rotating plate 10, it can drive the rotating plate 10 to move up and down together, so that the vibrating assembly can move up and down while rotating, thereby improving the vibration and stirring effect;

[0071] S6, when the spacing between adjacent vibrating mechanisms 5 needs to be adjusted, the operation S3 can be repeated;

[0072] S7, after the vibration and mixing are completed, operate S3 to shrink the movable plate 3. After shrinking, start the second driving device again to flip the swing frame 2 to be parallel to the mounting frame assembly.

[0073] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. The basic concept of the present invention is that after pouring, the fluidized solidified soil needs to be slightly vibrated to make the poured fluidized solidified soil dense and uniform, so as to solve the problem that the gap between the vibrating rods at the current stage cannot be adjusted, so that the vibration range remains unchanged during vibration, and it takes a long time to vibrate and compact the concrete at the same position. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the claims of the present invention.
