Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening machine technology, and in particular to a screening device for recycled construction waste. Background Technology
[0002] Recycled construction waste is a reusable material obtained by processing construction waste. It originates from waste generated during the demolition and construction process and is processed through sorting, crushing, screening and other processes. The most common type is recycled concrete aggregate.
[0003] Existing recycled aggregates require screening by a vibrating screen to determine their size. However, when aggregates are fed into the vibrating screen, the screening process is difficult because a large amount of aggregates cannot be spread evenly and tends to accumulate, resulting in poor filtration. To address this issue, we propose a screening device for recycled construction waste to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a screening device for recycled construction waste.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, the installation mechanism includes mounting bolts, and mounting plates are installed on both sides of the upper part of the screening machine frame by mounting bolts. A fixing frame rod is fixedly connected to the upper part of the mounting plate. The fixing frame rod is U-shaped in cross-section, which facilitates the installation of the fixing frame.
[0008] Preferably, the driving mechanism includes a fixed frame, the fixed frame is fixedly connected to the inner wall of the top of the fixed frame rod, and a drive motor is installed on the outer side of the fixed frame. The output end of the drive motor is connected to a pulley, and a lever is fixed to the end face of the pulley. The lever is inserted into the driving block, and the drive motor can drive the pulley and the lever to move the driving block back and forth.
[0009] Preferably, the actuating rod is cylindrical, the drive block has a strip-shaped slide adapted to the actuating rod inside, a first slider is fixedly connected to the outside of the drive block, and a strip-shaped through groove adapted to the first slider is provided on the inner wall of the fixed frame. By setting the actuating rod to be cylindrical, wear between it and the drive block can be reduced.
[0010] Preferably, the pushing mechanism includes a fixed column, and the fixed column is fixedly connected to the lower part of the driving block. The lower part of the fixed column is connected to the pushing rod through a pushing spring. The fixed column and the pushing rod can drive the entire actuating mechanism to move.
[0011] Preferably, the push rod has a groove inside that matches the fixed post, and a second slider is fixedly connected to the lower surface of the fixed post. The inner wall of the groove has a sliding groove that matches the second slider. Through the groove inside the push rod, the push rod can move along the surface of the fixed post.
[0012] Preferably, the actuating mechanism includes a hinge seat, the lower part of the push rod is hinged to the hinge seat, and the lower part of the hinge seat is fixedly connected to a push rod. The surface of the push rod is provided with bristles, which can facilitate the actuation of the aggregate.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. This device, through the rotation of the drive motor, causes the pulley to move the actuating rod within the fixed frame. The actuating rod then causes the driving block to reciprocate along the inside of the fixed frame. At this time, the driving block causes the entire pushing mechanism to move the push rod along the surface of the screening bin through the hinge seat, which facilitates the movement of the aggregate on the surface of the screening bin, effectively improving the screening effect of the screening bin and avoiding clogging that affects the filtration effect.
[0015] 2. This device uses the elastic force of the spring itself to make the push rod move up and down along the surface of the fixed column, so that the push rod can push the push rod to keep it in contact with the surface of the screening mesh, improving the pushing effect. The second slider fixedly connected to the end of the fixed column can limit and guide the push rod, and at the same time, it can raise and lower the push rod in a fixed direction, which facilitates the use of the push rod.

By hingedly installing the toggle mechanism 6, the toggle mechanism 6 can be kept in contact with the surface of the screening mesh bin 2.
[0027] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the installation mechanism 3 includes mounting bolts 31. Mounting plates 32 are installed on both sides of the upper part of the screening machine frame 1 through mounting bolts 31, and a fixed frame rod 33 is fixedly connected to the upper part of the mounting plate 32. The mounting bolts 31 pass through the mounting plate 32 and are connected to the screening machine frame 1, which makes it convenient to disassemble and maintain the fixed frame rod 33 as a whole.
[0028] Furthermore, refer to Figure 2 and Figure 3It can be seen that the driving mechanism 4 includes a fixed frame 41. The fixed frame 41 is fixedly connected to the inner wall of the top of the fixed frame rod 33. The fixed frame 41 facilitates the installation of the drive motor 42 and the pulley 43. The drive motor 42 is installed on the outer side of the fixed frame 41. The output end of the drive motor 42 is connected to the pulley 43. The end face of the pulley 43 is fixed with a lever 44. The lever 44 is inserted into the driving block 45. The pulley 43 drives the lever 44 to move back and forth in the fixed frame 41, so that the lever 44 can drive the driving block 45 to move.
[0029] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the actuating lever 44 is cylindrical, and the inside of the driving block 45 is provided with a strip-shaped slide that matches the actuating lever 44. The outer side of the driving block 45 is fixedly connected to the first slider 46, and the inner wall of the fixed frame 41 is provided with a strip-shaped through groove that matches the first slider 46. Through the strip-shaped slide inside the driving block 45, the actuating lever 44 can move along the strip-shaped slide, which facilitates the movement of the driving block 45. At the same time, through the movement of the driving block 45, the first slider 46 can move along the strip-shaped through groove, which facilitates the guidance of the driving block 45.
[0030] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the pushing mechanism 5 includes a fixed column 51, and the fixed column 51 is fixedly connected to the lower part of the driving block 45. The lower part of the fixed column 51 is connected to the pushing rod 53 through the pushing spring 52. The pushing rod 53 can be easily pushed by the elastic force of the pushing spring 52.
[0031] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the inside of the push rod 53 is provided with a groove that matches the fixed post 51. The lower surface of the fixed post 51 is fixedly connected to the second slider 54. The inner wall of the groove is provided with a sliding groove that matches the second slider 54. By moving the push rod 53 along the surface of the fixed post 51, the second slider 54 can slide in the sliding groove, which plays the role of limiting and guiding the push rod 53.

Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 The drive motor 42 can drive the pulley 43 to move the actuating rod 44 inside the fixed frame 41. When the actuating rod 44 moves, it can move along the slide rail opened inside the driving block 45, which facilitates the reciprocating movement of the driving block 45 inside the fixed frame 41. The first slider 46 can guide and limit the action of the driving block 45. When the driving block 45 moves, the fixed column 51 can drive the push rod 53 to move. When the push rod 53 moves, the hinge seat 61 can drive the push rod 62 to reciprocate along the inner wall of the screening bin 2, which facilitates the push rod 62 to move the aggregate and improve the filtration effect of the screening bin 2. At the same time, the spring 52 can be pushed by its own elasticity to facilitate the action of the push rod 53. At this time, the push rod 53 keeps the push rod 62 in contact with the inner wall of the screening bin 2 through the hinge seat 61.
