[0029] See Figure 1 and Figure 2 The civil engineering construction waste treatment device of this utility model includes: a box 1 and a crushing component 2, two crushing rollers 210 and a dust collection mechanism 3 disposed inside the box 1; wherein, the crushing component 2 and the two crushing rollers 210 are located on the first side inside the box 1; the crushing component 2 is disposed on the upper part inside the box 1 and is used to crush the construction waste entering from the feed port on the box 1; the two crushing rollers 210 are arranged in parallel and rotated in the horizontal direction below the crushing component 2 and are used to further crush the construction waste after the initial crushing by the crushing component 2; the dust collection mechanism 3 is disposed on the other side inside the box 1 and is used to collect the dust in the construction waste after it has been crushed by the two crushing rollers 210.

[0030] Specifically, a feed inlet is provided on one side of the top of the box 1, and a feed plate 201 is inclinedly arranged inside the inlet to guide construction waste into the box 1; at the junction of the box 1 and the feed plate 201, a placement plate 204 is arranged horizontally, and the placement plate 204 is slidably connected to the side wall of the box 1 so that the construction waste falls down.

[0031] The interior of the housing 1 is equipped with a vertical partition that separates the crushing assembly 2, the crushing rollers 210, and the ash collection box 301. Specifically, the crushing assembly 2 and the two crushing rollers 210 are located on the first side, while the ash collection box 301 is located on the second side of the partition and below the feed plate 201. The bottom end of the feed plate 201 is connected to the top end of the partition.

[0032] In this embodiment, the placement plate 204 can be arranged horizontally. One end of the placement plate 204 is connected to the bottom end of the feed plate 201, and the other end is slidably inserted through the side wall of the housing 1. Racks 205 are respectively provided on both sides of the lower surface of the placement plate 204. First gears 208 are correspondingly provided on both sides of the outer wall of the housing 1 below the placement plate 204.

The two first gears 208 mesh with the corresponding racks 205, which drives the placement plate 204 to move. The movement of the placement plate 204 causes the concrete waste to fall into the crushing area of ​​the two crushing rollers 210.

[0035] In this embodiment, the crushing component 2 includes a hydraulic rod 202 and a crushing plate 203. The hydraulic rod 202 passes through the top wall of the housing 1, and its output end is connected to the crushing plate 203 to drive the crushing plate 203 to move up and down for preliminary crushing of the construction waste. The hydraulic rod 202 can be an electric hydraulic rod 202, including a hydraulic cylinder, a piston rod, a hydraulic pump, an electric motor, and a control valve assembly. The electric motor drives the hydraulic pump to convert electrical energy into hydraulic energy. The control valve adjusts the flow of hydraulic oil, pushing the piston rod to perform linear reciprocating motion within the hydraulic cylinder. This electric hydraulic rod 202 integrates the power system and the actuator into one unit, allowing independent operation without an external hydraulic station. It has advantages such as compact structure, convenient operation, and fast response speed.

[0036] The cleaving plate 203 has a toothed surface facing the placement plate 204 to perform preliminary cleaving on the incoming construction waste.

[0037] Two crushing rollers 210 are arranged along the depth of the box 1 and are rotatably connected to the side wall of the box 1. They rotate in opposite directions, so that they mesh with each other and crush the construction waste. A collection box 217 is provided below the two crushing rollers 210 to collect the crushed waste.

[0038] The crushing roller 210 may include a cylindrical body and a plurality of toothed protrusions; the plurality of toothed protrusions are evenly distributed on the surface of the cylindrical body, and grooves are formed between adjacent protrusions. Preferably, the toothed protrusions are arranged in a spiral shape to enhance the shearing and crushing effect on construction waste; the grooves extend along the spiral direction, which helps the waste to be effectively transported and dispersed during the crushing process and avoids clogging.

[0039] In this embodiment, the construction waste can be concrete waste.

[0040] It is evident from the above that the civil engineering construction waste treatment device provided in this embodiment performs preliminary crushing of the construction waste entering the box 1 through the crushing component 2, achieving rapid decomposition of large pieces of waste; through the extrusion crushing area formed below by the two crushing rollers 210, it achieves secondary fine extrusion crushing of the waste, significantly improving crushing efficiency and uniformity; through the dust collection mechanism 3 set on the other side of the box 1, it achieves effective collection of dust generated during the crushing process, improving the working environment and facilitating recycling.

[0041] See Figures 2 to 3 In the above embodiment, an installation box 211 is provided on the side wall of the box 1. A second gear 212 is rotatably connected to one side of the inner wall of the installation box 211, and a third gear 213 is rotatably connected to the other side. The second gear 212 and the third gear 213 mesh with each other. The second gear 212 and the third gear 213 are respectively connected to the two ends of the two crushing rollers 210 to drive the two crushing rollers 210 to rotate in opposite directions, so that the two mesh with each other and crush the construction waste.

[0042] Specifically, the second gear 212 and the third gear 213 are respectively mounted on a rotating shaft 215. The two rotating shafts 215 are rotatably connected to the inner wall of the mounting box 211 on the side away from the crushing roller 210. A second motor 216 is provided on the outside of the mounting box 211, and the output shaft of the second motor 216 is fixedly connected to one of the rotating shafts 215. In specific implementation, the second motor 216 is started, which drives the rotating shaft 215 to rotate, causing the third gear 213 to rotate and mesh with the second gear 212. This causes the third gear 213 to drive one crushing roller 210 to rotate clockwise or counterclockwise, and the second gear 212 to drive the other crushing roller 210 to rotate counterclockwise or clockwise. Finally, the two crushing rollers 210 mesh and squeeze each other, further crushing the concrete waste.

[0043] Continue reading Figure 2 In the above embodiment, inside the housing 1, guide plates 214 are respectively inclinedly arranged on both sides below the crushing component 2 and above the two crushing rollers 210. The upper end of the guide plate 214 is close to the discharge port of the crushing component 2, and the lower end extends to the feeding area of ​​the crushing roller 210, which is used to guide the waste into the crushing roller 210.

[0044] Specifically, two guide plates 214 are arranged at an angle, with a notch between them to allow waste material to fall. The guide plates 214 can be angled panels with their lower ends aligned with the feed inlet of the crushing roller 210, used to evenly guide the crushed construction waste between the crushing rollers 210, preventing waste accumulation and ensuring efficient crushing. Preferably, the inclination angle of the guide plates 214 is 30-60°, more preferably 45°.

[0045] Combination Figure 1 and Figure 4 In this embodiment, a dust collection box 301 is slidably connected to the inner wall surface of the box 11. A filter plate 302 is fixedly installed on one side of the dust collection box 301. An air pump 303 is fixedly installed on one side of the inner wall of the box 1. An exhaust pipe 304 is fixedly installed on one side of the air pump 303. When the air pump 303 is started, the air pump 303 draws air from the device and discharges it through the exhaust pipe 304. At the same time, dust flows into the dust collection box 301 with the airflow. After being filtered by the filter plate 302, the air is discharged through the exhaust pipe 304. The dust remains in the dust collection box 301 for subsequent centralized treatment.

[0046] In the above embodiments, the dust collection mechanism 3 includes: a dust collection box 301, a filter plate 302, and several exhaust components; wherein, the dust collection box 301 has a drawer-type structure and is slidably connected to the housing 1; the dust collection box 301 has multiple channels on the side near the crushing component 2 to allow dust and airflow to enter the dust collection box 301; the filter plate 302 is located inside the dust collection box 301 on the side away from the crushing component 2; each of the exhaust components is arranged near the outlet of the filter plate 302 to discharge the air filtered by the filter plate 302.

[0047] Specifically, connecting plates are provided at the upper and lower ends of the dust collection box 301 inside the housing 1. A slide rail is provided on the lower connecting plate, allowing the dust collection box 301 to slide smoothly to the housing 1. The aperture of the channel is slightly larger than the aperture of the filter holes on the filter plate 302. The exhaust assembly includes an air pump 303 and an exhaust pipe 304; the input end of the air pump 303 is positioned directly opposite the filter plate 302, and the output end of the air pump 303 is connected to the exhaust pipe 304. The air pump 303 can be placed between the two connecting plates at the upper and lower ends, and the exhaust pipe 304 extends through the side wall of the housing 1 to discharge airflow to the outside.

[0048] In practice, the air pump 303 is started, the air pump 303 draws air from inside the device and discharges it from the device through the exhaust pipe 304. At the same time, the dust flows with the airflow into the dust collection box 301. After being filtered by the filter plate 302, the air is discharged from the device through the exhaust pipe 304. The dust remains inside the dust collection box 301 for subsequent centralized treatment.

[0049] All electrical devices in this plan are powered by an external power source.

[0050] Combination Figures 1 to 4 The working principle of this utility model is as follows: When using the device, it should first be placed in the designated position, and then the concrete waste should be placed on the feeding plate 201. The concrete waste slides down the feeding plate 201 onto the placement plate 204. The hydraulic rod 202 is activated to drive the crushing plate 203 to move up and down to initially crush the concrete waste. Then, the first motor 209 is activated to drive the rotating roller 207 and the first gear 208 to rotate. The first gear 208 meshes with the rack 205, driving the rack 205 and the placement plate 204 to move. The movement of the placement plate 204 causes the concrete waste to be crushed. The soil waste falls, and the falling concrete waste falls between the two crushing rollers 210 through the guide plate 214. At the same time, the second motor 216 is started. The second motor 216 drives the rotating shaft 215 to rotate, causing the third gear 213 to rotate and mesh with the second gear 212. This causes the third gear 213 to drive one crushing roller to rotate clockwise or counterclockwise, and the second gear 212 to drive the other crushing roller to rotate counterclockwise or clockwise. Finally, the two crushing rollers mesh and squeeze each other, further crushing the concrete waste. The crushed waste is then collected in the collection box 217. When the device is in use, the air pump 303 is started. The air pump 303 draws air from inside the device and discharges it through the exhaust pipe 304. At the same time, dust flows with the airflow into the dust collection box 301. After being filtered by the filter plate 302, the air is discharged from the device through the exhaust pipe 304, and the dust remains inside the dust collection box 301 for subsequent centralized processing.

[0051] In summary, the civil engineering construction waste treatment device provided by this utility model has the following beneficial effects:

[0052] 1. This civil engineering construction waste treatment device, by being equipped with a crushing mechanism, solves the problem that the particles after crushing in previous waste treatment devices were still too large to meet the requirements for further recycling. It enables the concrete waste to be crushed first, and then the crushed material to be further pulverized, so that the concrete waste is treated more fully and the recycling rate of concrete waste is improved.

[0053] 2. This civil engineering construction waste treatment device is equipped with an ash collection mechanism. Through the coordinated use of the ash collection box, filter plate, air pump, and exhaust pipe, the ash collection box can collect the dust generated during the use of the device. This achieves the beneficial effects of reducing the content of particulate matter in the air, improving the quality of the surrounding atmospheric environment, reducing the dust concentration in the workplace air, creating a relatively clean working environment for workers, and reducing the probability of occupational diseases.
