Description

Technical Field

[0001] The invention relates to the technical field of foundation pit backfill soil, in particular to a device for uniformly distributing backfill soil in a deep foundation pit of a building. Background Art

[0002] Backfill refers to the compacted soil that is returned after the foundation and other below-ground projects are completed during construction. Backfill refers to the construction process of taking soil and backfilling within five meters after the completion of concealed projects such as foundation and cushion layer. Earthwork backfill is the backfill of construction projects, which mainly includes foundation backfill, foundation pit or pipe trench backfill, indoor floor backfill, outdoor site backfill and leveling, etc. Foundation pit backfill is the basic process of construction and is related to the quality of the project. During the foundation pit backfill process, the moisture content of the backfill needs to be tested. When the moisture content is too high, the dry soil needs to be mixed with the backfill to reduce the moisture content of the backfill and ensure the quality of the later project. When the existing foundation pit backfill mixing device is unloaded, the backfill and dry soil are piled on one side of the mixing box, and the backfill and dry soil are not easy to be evenly distributed in the mixing box.

[0003] After searching, Chinese patent application No. 201922384342.9 discloses a stirring device for foundation pit soil backfill that is easy to mix evenly. The patent drives the push plate to slide left and right on the receiving plate through the rotation of the screw rod, flattens the backfill soil or dry soil on the receiving plate, and makes the backfill soil or dry soil evenly distributed in the mixing box. Although the above patent has the function of uniform material discharge, the filtration is easy to be clogged. Since the filter plate is fixed during filtration, the agglomerated soil is easy to accumulate, causing clogging, and the inner wall of the current distribution device is easy to stick to the soil, which makes cleaning inconvenient after agglomeration for a long time. Therefore, it is necessary to design a uniform distribution device for backfill soil in deep foundation pits of buildings. Summary of the Invention

DETAILED DESCRIPTION

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example like Figure 1-6 As shown, a device for evenly distributing backfill soil in a deep foundation pit of a building is shown, comprising a box body 1. A chute 2 is provided on one side of the inner wall of the box body 1 near the top. A slide plate 3 is slidably connected to the interior of the chute 2.

A notch 6 is provided on the outer surface of the box body 1 near the L-shaped plate 5. In this embodiment, the notch 6 is movably connected to the L-shaped plate 5, the inner wall of the box body 1 is rotatably connected to the transmission rod 7, the outer surface of the transmission rod 7 is fixedly connected to the stirring rod 8, one end of the transmission rod 7 passes through the inner wall of the box body 1 and extends to the outer surface of the box body 1, one end of the transmission rod 7 is fixedly connected to the swash plate 9, the swash plate 9 is movably connected to the L-shaped plate 5, and a motor 10 is installed on the other side of the box body 1, and the output end of the motor 10 is fixedly connected to the transmission rod 7.

[0018] During specific use, when mixing dry soil with backfill soil to adjust the moisture content of the backfill soil, mechanical equipment can be used to pour the backfill soil and dry soil into the filter frame 4 respectively. The filter frame 4 can screen foreign matter or large pieces of soil, and the filtered soil falls into the interior of the box body 1. The motor 10 is started to drive the transmission rod 7 to rotate, so that the stirring rod 8 mixes the internal soil to ensure the moisture content. While the transmission rod 7 rotates, it drives the inclined plate 9 at one end. At the same time, the slide plate 3 can slide inside the slide 2, so that the filter frame 4 can slide horizontally left and right. When the inclined plate 9 continues to rotate, it drives the L-shaped plate 5 in the horizontal direction to bear force, so that the L-shaped plate 5 continuously pushes and pulls the filter frame 4. The continuous shaking of the filter frame 4 can greatly reduce the accumulation of soil blocks, thereby increasing the filtering effect.

[0019] In this embodiment, one end of the outer surface of the transmission rod 7 close to the swash plate 9 is fixedly connected to a driving wheel 11 , and a chain 12 is overlapped inside the driving wheel 11 . There are two chains 12 .

[0020] During specific use, through the overlapping effect of the driving wheel 11 and the chain 12, the transmission rod 7 can drive the driving wheel 11 after rotation, so that the driving wheel 11 can drive the chain 12 after rotation, thereby producing a transmission effect.

[0021] In this embodiment, both sides of the outer surface of the box body 1 near the bottom are rotatably connected to support rods 13, one side of the outer surface of the support rod 13 is fixedly connected to a touch plate 14, and one end of the support rod 13 is fixedly connected to a driven wheel 15, which is overlapped with the chain 12.

[0022] During specific use, through the overlapping effect of the driven wheel 15 and the chain 12, the driving wheel 11 drives the chain 12 to rotate, so that the driven wheel 15 is forced to drive the support rod 13 to rotate.

[0023] In this embodiment, a support seat is fixedly connected to one side of the outer surface of the box body 1 near the bottom, a movable rod is rotatably connected to the inner side wall of the support seat, a striking plate 16 is fixedly connected to the outer surface of the movable rod, and a torsion spring 17 is fixedly connected to one end of the movable rod, and one end of the torsion spring 17 is fixedly connected to the support seat.

[0024] During specific use, the movable rod rotates in the support seat, and the torsion spring 17 applies force to the movable rod, so that the top of the striking plate 16 always contacts the surface of the box body 1. After the striking plate 16 is flipped and separated by the force, a striking effect can be produced.

[0025] In this embodiment, a discharge port 18 is provided on the lower surface of the box body 1, and a screw rod 19 is threadedly connected to one side of the outer surface of the box body 1 near the bottom. One end of the screw rod 19 is rotatably connected to a sealing plate 20, and the sealing plate 20 is tightly attached to the lower surface of the box body 1.

[0026] During specific use, after the soil and materials in the box body 1 are mixed through the evenly arranged discharge ports 18, the screw rod 19 can be rotated to make the sealing plate 20 slide to one side. By staggering the sealing plate 20 and the discharge ports 18, multiple discharge ports 18 can be exposed at the same time, which is convenient for even distribution of the backfill soil.

[0027] In this embodiment, one end of the screw rod 19 is fixedly connected to a handle 21 , and the other side of the sealing plate 20 is fixedly connected to a sliding rod, and the sliding rod is slidably connected to the box body 1 .

[0028] During specific use, the sliding rod at one end of the sealing plate 20 is used to slide with the box body 1, so that the sealing plate 20 can slide after receiving the force of the screw rod 19, so as to expose the discharge port 18.

[0029] In this embodiment, a support leg 22 is fixedly connected to one side of the outer surface of the box body 1 close to the bottom, and a driving wheel 23 is provided at the bottom end of the support leg 22 .

[0030] During specific use, the supporting legs 22 provide a firm support function, and the driving wheels 23 facilitate movement of the material distributing device.

[0031] Working principle: During use, when the dry soil is mixed with the backfill soil to adjust the moisture content of the backfill soil, mechanical equipment can be used to pour the backfill soil and dry soil into the filter frame 4 respectively. The filter frame 4 can screen out foreign matter or large pieces of soil, and the filtered soil falls into the inside of the box body 1. The motor 10 is started to drive the transmission rod 7 to rotate, so that the stirring rod 8 mixes the internal soil to ensure the moisture content. While the transmission rod 7 rotates, it drives the inclined plate 9 at one end. At the same time, the slide 3 can slide inside the slide 2, so that the filter frame 4 can slide horizontally left and right. When the inclined plate 9 continues to rotate, it drives the L-shaped plate 5 in the horizontal direction to be subjected to force, so that the L-shaped plate 5 continuously pushes and pulls the filter frame 4. The continuous shaking of the filter frame 4 can greatly reduce the accumulation of soil blocks, thereby increasing the filtering effect. While the motor 10 drives the transmission rod 7 to rotate, the driving wheel 11 drives the chain 12 to rotate, so that the driven wheel 15 drives the support The rod 13 rotates, and the movable rod has a rotating effect in the support seat through the movable rod, and the torsion spring 17 subjects the movable rod to a force, so that the top of the striking plate 16 always contacts the surface of the box body 1, and the support rod 13 rotates to drive the touch plate 14 to contact the bottom end of the striking plate 16 and produce a squeezing effect. At this time, the torsion spring 17 is deformed, and when the touch plate 14 disengages from the striking plate 16 after continuing to rotate, the movable rod is not subjected to the force and utilizes the rebound effect of the torsion spring 17 to make the striking plate 16 strike both sides of the box body 1, producing a certain vibration effect, and the striking plate 16 is of appropriate length, which can enable the touch plate 14 to continue to rotate and then disengage, greatly reducing the sticking of soil blocks on the inner wall of the box body 1 and avoiding the difficulty in cleaning after agglomeration. After the soil and material in the box body 1 are mixed, the rotating screw 19 can make the sealing plate 20 slide to one side, and the sealing plate 20 is misaligned with the discharge port 18, so that multiple discharge ports 18 can be exposed at the same time, which is convenient for uniform distribution of backfill soil.
