Description

Technical Field

[0001] This utility model relates to the field of building engineering technology; more specifically, it relates to a construction waste crushing device for building engineering. Background Technology

[0002] Construction waste crushing equipment is a type of mechanical equipment specifically designed for processing construction waste. It is mainly used to crush concrete blocks, bricks, tiles, metals, wood, and other construction waste to achieve resource recycling. Its core function is to crush large pieces of waste into recycled aggregates for use in roadbeds, recycled building material production, and other applications.

[0003] Currently, existing construction waste crushing devices for building engineering have limitations. They may not crush construction waste thoroughly, making subsequent reuse inconvenient and reducing the device's practicality. Furthermore, the crushing process generates significant dust, which not only harms workers' health but also potentially causes equipment malfunctions, further diminishing the device's usability. Therefore, there is an urgent need for a construction waste crushing device for building engineering to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a construction waste crushing device for construction engineering, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a construction waste crushing device for construction engineering, comprising:

[0006] The box body has a crushing structure inside and a dust suppression structure on one side.

[0007] The crushing structure includes a motor, which is mounted on the outer surface of the other side of the housing.

[0008] The dust suppression structure includes a water pump, which is installed on the outer surface of one side of the housing.

[0009] Preferably, the crushing structure further includes crushing rollers, and there are two sets of crushing rollers. The two sets of crushing rollers are respectively bearing connected to the inner surface of the outer surfaces of both ends of the upper end of the housing. Gears are fixedly connected to the outer surface of one side of each set of crushing rollers. A first filter plate is fixedly connected to the inside of the housing. An installation groove is fixedly connected to the outer surface of the other side of the housing, and a collection bin is inserted into the installation groove. A second filter plate is fixedly connected to the lower end of the first filter plate inside the housing. A discharge port is fixedly connected to the outer surface of the lower end of the other side of the housing. This design allows the crushing rollers to rotate by starting the motor.

[0010] Preferably, the two sets of gears mesh with each other, and the output end of the motor is fixedly connected to the outer surface of one side of one of the two sets of crushing rollers. This design allows the two sets of crushing rollers to rotate simultaneously through the meshing of the two sets of gears.

[0011] Preferably, both the first filter plate and the second filter plate are filter screens, and the internal size of the mesh of the first filter plate is larger than that of the mesh of the second filter plate. The lower end of the outer side of the mounting groove is provided with a limiting plate, and the inner surface of the limiting plate is in contact with the outer surface of the outer side of the collection bin. This design allows the incompletely crushed construction waste to slide into the interior of the collection bin through the filtration of the first filter plate.

[0012] Preferably, the dust suppression structure further includes a connecting pipe, the lower end of which is connected to the output end of the water pump. The upper end of the connecting pipe is connected to a diversion pipe, and spray holes are opened on the inner surfaces of the outer surfaces of both inner ends of the diversion pipe. A sealing cap is threadedly connected to the inner surface of the lower outer surface of one end of the housing, and a drain outlet is connected to the inner surface of the outer surface of one side of the lower end of the housing. This design allows water inside the lower end of the housing to enter the interior of the diversion pipe through the connecting pipe and be sprayed through the spray holes by starting the water pump.

[0013] Preferably, the spray holes are provided in multiple sets, and the multiple sets of spray holes are evenly arranged inside the outer surface of the diverter pipe. This design, through the arrangement of the spray holes, can make the spraying more uniform.

[0014] The technical effects and advantages of this utility model are as follows: By starting the motor and engaging the gears, this utility model can drive two sets of crushing rollers to rotate synchronously, which can crush the input construction waste. The construction waste falls to the upper end of the first filter plate. At the same time, through the filtration of the first filter plate, the more completely crushed waste falls down to the upper end of the second filter plate and slides into the discharge port for further processing. The larger and incompletely crushed construction waste slides into the collection bin from the outer surface of the upper end of the first filter plate. When there is a lot of waste in the collection bin, the collection bin can be lifted out and poured back in from the opening at the top of the box for secondary crushing. Thus, the construction waste is crushed more thoroughly through multiple crushing processes, avoiding unsuitable conditions when the construction waste is recycled and reused, and improving the practicality of the equipment to a certain extent.

[0015] By opening the sealed cover, water can be injected into the chamber. Then, the water pump is started, which drives the water from the lower part of the chamber through the connecting pipe into the distribution pipe. The water is then sprayed through multiple sets of nozzles to reduce dust. The water after dust reduction is filtered by the second filter plate and can be recycled back into the lower part of the chamber. This allows for reuse while reducing dust, improving water resource utilization and enhancing the practicality of the equipment. Moreover, its overall structure is simple and reasonable, highly practical, and easy to promote and apply. Attached Figure Description

Detailed Implementation

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The construction waste crushing device for construction engineering involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] like Figures 1-3 As shown in the figure, this embodiment proposes a construction waste crushing device for construction engineering, comprising:

[0024] Box 1, the interior of box 1 is equipped with crushing structure 2, and one side of box 1 is equipped with dust suppression structure 3;

[0025] The crushing structure 2 includes a motor 21, which is mounted on the outer surface of the other side of the housing 1. The crushing structure 2 also includes crushing rollers 22, and there are two sets of crushing rollers 22. The two sets of crushing rollers 22 are respectively connected to the inner surface of the outer surface of the upper two sides of the housing 1 by bearings. Gears 23 are fixedly connected to the outer surface of one side of each set of crushing rollers 22. The two sets of gears 23 mesh with each other. The output end of the motor 21 is fixedly connected to the outer surface of one side of one set of crushing rollers 22. This design can drive one set of crushing rollers 22 to rotate by starting the motor 21. At the same time, through the meshing of the two sets of gears 23, the two sets of crushing rollers 22 can rotate simultaneously in opposite directions.

[0026] A first filter plate 24 is fixedly connected inside the housing 1. A mounting groove 25 is fixedly connected to the outer surface of the other side of the housing 1, and a collection chamber 26 is inserted inside the mounting groove 25. A second filter plate 27 is fixedly connected to the lower end of the first filter plate 24 inside the housing 1. A discharge port 28 is fixedly connected to the outer surface of the lower end of the other side of the housing 1. Both the first filter plate 24 and the second filter plate 27 are filter screens, and the internal size of the mesh of the first filter plate 24 is larger than the internal size of the mesh of the second filter plate 27. The lower end of the mounting groove 25 on the outer side is provided with... The limiting plate has its inner surface in contact with the outer surface of the collection bin 26. This design allows the completely crushed construction waste to fall through the first filter plate 24 onto the outer surface of the upper end of the second filter plate 27, while larger, incompletely crushed construction waste slides into the collection bin 26 from the outer surface of the first filter plate 24. At the same time, the limiting plate supports the outer surface of the collection bin 26, preventing the collection bin 26 from moving outward when it slides into the collection bin 26.

[0027] Example 2

[0028] like Figure 4 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0029] The dust suppression structure 3 includes a water pump 31, which is installed on the outer surface of one side of the housing 1. The dust suppression structure 3 also includes a connecting pipe 32, the lower end of which is connected to the output end of the water pump 31. The upper end of the connecting pipe 32 is connected to a diversion pipe 33, and spray holes 34 are opened inside the outer surface of both sides of the inner end of the diversion pipe 33. A sealing cover 35 is threaded inside the outer surface of the lower end of one end of the housing 1. A drain outlet 36 is connected inside the outer surface of one side of the lower end of the housing 1. Multiple sets of spray holes 34 are provided, and the multiple sets of spray holes 34 are evenly arranged inside the outer surface of the diversion pipe 33.

[0030] In this embodiment, by starting the water pump 31, water inside the lower end of the housing 1 can be driven into the interior of the diversion pipe 33 through the connecting pipe 32 and sprayed through the nozzles 34. This process reduces dust while crushing construction waste. The even arrangement of multiple sets of nozzles 34 prevents excessive or inadequate spraying in certain areas. After dust reduction, the water enters the interior of the housing 1 and is filtered by the second filter plate 27 before re-entering the lower end of the housing 1. It can then be pumped out again by the water pump 31.

[0031] Working principle: When using the equipment, first open the sealing cover 35 and inject the water required for dust suppression into the lower part of the box 1. Then, put the construction waste into the box 1 through the opening at the upper part. Next, start the motor 21. Through the meshing of the gear 23, drive the two sets of crushing rollers 22 to rotate simultaneously to crush the construction waste. At the same time, start the water pump 31, which drives the water inside the box 1 to enter the diversion pipe 33 through the connecting pipe 32 and spray it through the spray holes 34 to suppress dust. After dust suppression, the water enters the interior of the box 1 and passes through the second filter plate 27. The filter can re-enter the interior of the lower end of the housing 1, and then be extracted again for dust suppression. Incompletely crushed construction waste will enter the interior of the collection chamber 26 through the first filter plate 24. When the collection chamber 26 is full of construction waste, the collection chamber 26 can be extracted from the interior of the mounting slot 25, and the waste inside can be put back into the opening at the upper end of the housing 1 for repeated crushing. Completely crushed construction waste will enter the interior of the discharge port 28 through the upper end of the second filter plate 27. After collection, it can be processed for subsequent treatment. The above is the entire working principle of this utility model.

[0032] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
