Two crushing wheels are installed inside the housing, and a motor is located on one side of the housing. The motor and crushing wheels are connected by a belt. A receiving box is located at the bottom of the housing. This utility model addresses the problems of existing crushing devices being generally large and inconvenient to place on construction sites, and traditional small crushers being unsuitable for crushing hardened cement, leading to significant cement waste due to the difficulty in crushing damp, hardened cement. By improving and optimizing the structure of the crushing device, it achieves a smaller size while still being able to crush damp, hardened cement, thus facilitating its recycling and ensuring its full utilization, preventing significant cement waste caused by the inability to crush damp, hardened cement.

[0004] The existing crushing equipment still has at least the following two problems during use:

[0005] Question 1: The feed inlet of the machine casing is always open. During the crushing process of construction waste, a large amount of dust is generated, resulting in a large amount of dust at the feed inlet. This has a significant impact on the respiratory health of nearby workers.

[0006] Question 2: After construction waste is crushed by the crushing wheel, there are still some large-volume materials in the crushed material, resulting in a low crushing effect.

[0007] Therefore, in order to solve the above problems, a construction waste crushing device is proposed. Utility Model Content

[0008] To address the aforementioned technical problems, this utility model provides a construction waste crushing device. A dustproof mechanism is added to the feed inlet of the machine casing to prevent dust generated by the crushing mechanism inside the machine casing from coming out of the feed inlet and affecting nearby workers. A screening component is added below the crushing mechanism to ensure the qualified rate of the material discharged from the discharge port of the machine casing, greatly enhancing the crushing effect.

[0009] To achieve the above objectives, the technical solution of this utility model is as follows:

[0010] A construction waste crushing device includes a casing and a crushing mechanism. The crushing mechanism is installed inside the casing below the feed inlet. The device is characterized by having a dustproof mechanism installed at the feed inlet. Inside the casing, a first partition plate and a second partition plate are arranged sequentially from top to bottom. The first partition plate is located below the crushing mechanism. A screening assembly is installed between the first and second partition plates.

[0011] The crushing mechanism consists of a crushing motor, crushing rollers, a driving wheel, and a driven wheel.

The driving wheel meshes with the driven wheel, and the driving wheel is connected to the output end of the crushing motor.

[0012] The dustproof mechanism consists of a fixed frame, an electric push rod, a connecting rod, and a dustproof plate. The fixed frame is fixedly connected to both sides of the feed inlet on the machine housing. The electric push rod is fixedly installed at both ends of the fixed frame. The telescopic end of the electric push rod is connected to the dustproof plate through the connecting rod.

[0013] The dustproof plate has T-shaped sliders at both ends on its bottom surface, and the T-shaped sliders are slidably connected to grooves provided on the side wall of the feed inlet.

[0014] The screening assembly includes a vibrating motor, a screening plate, and a collection box. The screening plate is installed in an inclined manner inside the machine housing. The vibrating motor is mounted on the screening plate, and a screening screen is installed on the screening plate. The collection box is installed in a collection chamber on the machine housing, and a screening port is provided on one side wall of the collection chamber.

[0015] Specifically, the lowest end of the sieve plate is located at the sieve opening of the collection chamber.

[0017] Specifically, the connecting rod is connected by a guide rod, and both ends of the guide rod are fixed to the fixing frame.

[0018] Specifically, the first partition plate is provided with a discharge port.

[0019] Specifically, the discharge port on the second partition plate is connected to the discharge port at the bottom of the machine casing.

[0020] Specifically, the top wall of the collection chamber of the housing is provided with an observation window to facilitate observation of the collection status in the collection box.

[0021] The beneficial effects of this utility model are:

[0022] This utility model adds a dustproof mechanism to the feed inlet of the machine casing. When feeding is required, the telescopic end of the electric push rod in the dustproof mechanism retracts to control the two dustproof plates on the feed inlet to move in opposite directions, so that the feed inlet is in an open state. After feeding is completed, the electric push rod pushes out to control the two dustproof plates to move in opposite directions, so that the feed inlet is in a closed state, thereby preventing the dust generated by the crushing mechanism inside the machine casing when crushing materials from coming out of the feed inlet and affecting the nearby workers.

[0023] This invention adds a screening component below the crushing mechanism, so that the crushed material is screened by the screening plate, and the larger materials are screened out into the collection box. The workers take them out and pour them into the machine casing for secondary processing, which ensures the qualified rate of the material discharged from the discharge port of the machine casing and greatly enhances the crushing effect.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] Example 1

[0034] As shown in the figure, a crushing mechanism is installed inside the casing 1 below the feed inlet 11. The two ends of the central shafts of the two crushing rollers 24 of the crushing mechanism are respectively mounted on the casing 1 via bearings. One end of one crushing roller is connected to the driving wheel 22, and the other crushing roller 24 is connected to the driven wheel 23. The driving wheel 22 is engaged with the driven wheel 23, and the driving wheel 22 is connected to the output end of the crushing motor 21.

[0035] The fixed frames 31 in the dustproof mechanism are fixed on both sides of the feed inlet 11. Electric push rods 32 are fixedly installed at both ends of the fixed frames 31. The telescopic ends of the electric push rods 32 are connected to the dustproof plate 34 through connecting rods 33. The connecting rods 33 are sleeved with guide posts 35 fixedly installed on the fixed frames 31. The guide posts 35 guide the movement of the connecting rods 33. T-shaped sliders 341 are respectively provided at both ends of the bottom surface of the dustproof plate 34. The T-shaped sliders 341 are slidably connected in the grooves provided on the side wall of the feed inlet 11.

[0036] like Figure 5 As shown in the cross-sectional diagram, a first partition plate 4 and a second partition plate 5 are arranged sequentially from top to bottom inside the casing 1. The first partition plate 4 is located below the crushing mechanism, and a discharge port 41 is provided at the lowest position on the first partition plate 4. The discharge port provided on the second partition plate 5 is connected to the discharge port 12 at the bottom of the casing 1.

[0037] A screening assembly is installed between the first partition plate 4 and the second partition plate 5. The screening plate 62 in the screening assembly is inclined and installed inside the casing 1. A vibrating motor 61 is installed on the screening plate 62, and a screening mesh 63 is installed on the screening plate 62. A collection box 64 is installed inside a collection chamber 13 on the casing 1. A screening opening 131 is provided on one side wall of the collection chamber 13. The lowest point of the screening plate 62 is located at the screening opening 131 of the collection chamber 13, so that larger volume materials enter the collection chamber 13 through the screening opening 131 and fall into the collection box 64.

[0038] Specifically, an inclined plate 7 is provided at the screening port of the collection chamber 13 to facilitate the material falling into the collection box, and an observation window 132 is provided on the top wall of the collection chamber 13 of the casing 1 to facilitate the observation of the collection situation in the collection box 64 inside.

[0039] Example 2

[0040] When using this invention, when feeding material into the housing 1, the electric push rod 32 in the dustproof mechanism is activated. The telescopic end of the electric push rod 32 retracts to control the two dustproof plates 34 on the feed inlet to move in opposite directions, so that the feed inlet 11 is open, and the feeding operation can be carried out.

[0041] After the material is fed, the electric push rod 32 pushes out to control the two dustproof plates 34 to move towards each other, so that the feed port 11 is closed. This prevents the dust generated by the crushing mechanism inside the casing 1 when crushing materials from coming out of the feed port and affecting the nearby workers.

[0042] After closing the feed inlet 11, the crushing motor 21 in the crushing mechanism is started, causing the drive wheel 22 to mesh and drive the driven wheel 23 to rotate. This causes the two crushing rollers 24 inside the casing 1 to rotate and crush the material. The crushed material falls from the discharge port 41 on the first partition plate 4 onto the screening screen 63 of the screening plate 62.

[0043] Driven by the vibrating motor 61, the screening screen 63 vibrates and screens the material. The entire screening plate is set with an inclined structure. The qualified material falls onto the second partition plate 5 and is then discharged from the discharge port 12 of the casing 1. The larger material is screened onto the screening screen 63. Due to the inclined setting of the screening screen, the material on it slowly moves to the lowest end and then enters the collection chamber 13 from the screening port 131. Finally, it falls into the collection box 64. After the workers take it out, the unqualified material inside is poured into the casing 1 for secondary processing, which ensures the qualified rate of the material discharged from the discharge port 12 of the casing 1 and greatly enhances the crushing effect.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
