Description

Technical Field

[0001] The utility model relates to the technical field of building waste crushing, in particular to a building waste crushing device for construction. Background Art

[0002] Construction waste, also known as building waste, mainly comes from waste materials generated during construction, demolition or renovation. It includes a variety of materials, such as concrete, bricks, wood, metal, rubble, stone, plaster, plastic, etc. These materials usually come from the demolition of old buildings, the construction of new buildings, or the maintenance and renovation of buildings.

[0003] In the current construction industry, the amount of waste generated by construction and demolition activities is huge. The generated construction waste requires the use of garbage crushing devices to convert discarded concrete, bricks, stones and other building materials into usable aggregates and other recycled resources. When the existing crushing device is in use, the operator feeds the construction waste into the device through the feed port, and then the construction waste is crushed by the crushing roller, and finally the crushed construction waste falls into the aggregate box.

[0004] The existing construction waste crushing device has certain problems during the crushing operation. Since the feed port of the device is not blocked, hard objects such as stones and metal fragments will splash out during the crushing process, which not only increases the difficulty of cleaning the workplace, increases labor costs, but also reduces work efficiency. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a construction waste crushing device for construction, aiming to improve the problem in the prior art that hard objects such as stones and metal fragments will splash out during the crushing process due to the lack of shielding on the feed inlet of the device.

[0026] After the construction waste is poured into the feed port 6, the first motor 9 is started. At this time, the output end of the motor will drive the turntable 10 to rotate. The outside of the turntable 10 is fixedly connected with a fixed rod 11, and as the turntable 10 rotates, the fixed rod 11 will also rotate accordingly. The external rotation of the fixed rod 11 is connected to the connecting rod 12, and the connecting rod 12 moves under the action of the fixed rod 11. The bottom of the connecting rod 12 is connected to the sealing cover 13, so as the connecting rod 12 moves, the sealing cover 13 will also move accordingly. When the sealing cover 13 moves to a suitable position, it will fit tightly on the edge of the feed port 6, thereby completely covering the feed port 6, realizing that when the construction waste is crushed, it is convenient to cover the feed port 6, avoiding the splashing of hard objects such as stones and metal fragments when the construction waste is crushed, which can effectively reduce the spread of dust and noise and improve the surrounding working environment.

[0027] Reference Figure 1 and Figure 4An extension plate 19 is fixedly connected to the right side of the outside of the crushing box 2, and a third motor 21 is arranged at the lower part of the extension plate 19. A driving wheel 22 is fixedly connected to the output end of the third motor 21. A driven wheel 24 is rotatably connected to the left side of the outside of the driving wheel 22. The driving wheel 22 is connected to the driven wheel 24 through a belt 23. An extension rod 25 is fixedly connected to the right side of the upper part of the driven wheel 24. The extension rod 25 is rotatably connected to one end of a connecting rod 26. The other end of the connecting rod 26 passes through the inside of the crushing box 2 and is fixedly connected to a screening plate 27. Slide blocks 28 are fixedly connected to both sides of the outside of the screening plate 27. Slide blocks 29 are fixedly connected to both sides of the inside of the crushing box 2. The two slide blocks 28 are slidably connected to the outside of the two slide blocks 29. An L-shaped plate 20 is fixedly connected to the lower part of the extension plate 19, and the third motor 21 is fixedly connected to the upper part of the L-shaped plate 20.

[0028] During the crushing process of construction waste, the waste fragments will fall on the upper part of the screening plate 27. At this time, the third motor 21 is started, and the output end of the third motor 21 is fixedly connected to the driving wheel 22. When the motor is started, the driving wheel 22 starts to rotate. This rotation is transmitted to the driven wheel 24 through the belt 23, and the driven wheel 24 rotates with the extension rod 25 fixedly connected to the upper right side. The rotation of the extension rod 25 further drives the connecting rod 26 connected to the external rotation. The movement of the connecting rod 26 makes the screening plate 27 fixedly connected at the other end reciprocate outside the two sliding rods 29. The reciprocating motion of the screening plate 27 is the core of the screening work. Through this movement, the crushed construction waste is effectively screened. The garbage fragments of different sizes slide on the screening plate 27 due to the action of gravity, and the large particles of garbage fragments are left on the screening plate 27, while the small particles of garbage fragments fall through the gap of the screening plate 27. The screened construction waste will further fall to the upper part of the separation plate 30. The separation plate 30 is provided with holes of different sizes, through which the construction waste can be further separated. Construction waste larger than the holes of the separation plate 30 will be retained on the plate and then discharged through the first discharge port 4. Construction waste smaller than the holes of the separation plate 30 will fall into the second discharge port 5 through the holes and finally be discharged through the second discharge port 5, making it easy to screen and separate the crushed waste. Through screening and separation, useful materials such as metals, plastics, glass, etc. can be effectively recovered from the abandoned construction waste. These materials can be reused after proper treatment, thereby reducing resource waste.

[0029] Reference Figure 1 and Figure 2The crushing assembly 17 includes a second motor 1701, which is fixedly connected to the upper part of the connecting plate 16. The output end of the second motor 1701 is fixedly connected to the first gear 1702. The first gear 1702 is externally meshed with the second gear 1703. The first gear 1702 and the second gear 1703 are internally fixedly connected with a transmission rod 1704. The two transmission rods 1704 are rotatably connected to the inside of the crushing box 2. The two transmission rods 1704 are externally fixedly connected to crushing rollers 1705.

[0030] When crushing construction waste, by starting the second motor 1701, the second motor 1701 drives the second gear 1703 meshingly connected to the first gear 1702 to rotate, and when the first gear 1702 and the second gear 1703 rotate, the two transmission rods 1704 fixedly connected internally rotate, and the two transmission rods 1704 rotate and drive the two crushing rollers 1705 fixedly connected externally to rotate relative to each other, thereby realizing the crushing of construction waste and improving the crushing effect of construction waste.

[0031] Working principle: when crushing construction waste, first pour the construction waste from the feed port 6. After pouring the construction waste, start the first motor 9. The first motor 9 rotates the turntable 10 fixedly connected to the output end. The rotation of the turntable 10 rotates the fixed rod 11 fixedly connected to the outside. The fixed rod 11 rotates and moves the connecting rod 12 connected to the outside. The connecting rod 12 moves and moves the sealing cover 13 connected to the bottom, so that the sealing cover 13 blocks the feed port 6. When crushing construction waste, it is convenient to cover the feed port 6 to prevent hard objects such as stones and metal fragments from splashing out when the construction waste is crushed. The diffusion of dust and noise can be effectively reduced, and the surrounding working environment is improved. After the construction waste is crushed, it will fall on the upper part of the screening plate 27. Start the third motor 21. The third motor 21 rotates the driving wheel 22 fixedly connected to the output end. The driving wheel 22 rotates and drives the driven wheel 24 to rotate through the belt 23. The driven wheel 24 rotates and drives the extension rod 25 fixedly connected to the upper right side to rotate. The extension rod 25 rotates and drives the connecting rod 26 connected to the outside to rotate. The connecting rod 26 moves and drives the screening plate 27 fixedly connected at the other end to make reciprocating motion outside the two sliding rods 29. The crushed construction waste is screened by the reciprocating motion of the screening plate 27. The screened construction waste will fall to the upper part of the separation plate 30 and be separated by the separation plate 30. The construction waste larger than the holes of the separation plate 30 will be discharged through the first discharge port 4, and the construction waste smaller than the holes of the separation plate 30 will fall into the inside of the second discharge port 5 and be discharged through the second discharge port 5, which makes it easy to screen and separate the crushed garbage. Through screening and separation, useful materials such as metals, plastics, glass, etc. can be effectively recovered from discarded construction waste. These materials can be reused after proper treatment, thereby reducing resource waste.
