[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4As shown, this utility model provides a technical solution: a screening device for recycled aggregate from construction waste, including a base 1. Several fixed platforms 101 are fixedly connected to the top of the base 1. A telescopic rod 102 is fixedly installed at the top of each fixed platform 101. A screening box 104 is fixedly connected between the tops of each telescopic rod 102. A spring 103 is sleeved on the outer end of each telescopic rod 102. The top of each spring 103 is fixedly connected to the bottom of the screening box 104. The bottom of each spring 103 is fixedly connected to the top of each fixed platform 101. A screening box 104 is installed on the inner side of the screening box 104. The multi-stage screening plate 105 and the screening box 104 have several discharge ports on their side near the multi-stage screening plate. Each discharge port is fixedly connected to a downwardly inclined discharge box 106. The lengths of the discharge boxes 106 decrease sequentially from top to bottom. The multi-stage screening plate can screen aggregates of different sizes. The screened aggregates enter the discharge boxes 106 from each discharge port. Since each discharge box 106 is downwardly inclined and its length decreases sequentially from top to bottom, it is convenient for the aggregates to be discharged into different boxes for collection.

[0021] Furthermore, a base plate 2 is fixedly connected to the bottom end of the screening box 104, and a fixing plate 201 is fixedly connected to the bottom end of the base plate 2. Several limiting components 3 are provided at the bottom end of the fixing plate 201, and a vibrating component 4 is provided at the bottom end of the fixing plate 201. A dustproof box 5 is provided on the top outer end of the screening box 104, and several moving components 6 are provided at the bottom end of the dustproof box 5. Through the setting of the limiting components 3, when the vibrating component 4 is installed on the fixing plate 201, the vibrating component 4 can be initially limited, facilitating its installation and fixation on the fixing plate 201 and preventing [further issues]. To prevent misalignment of the screw hole 202 and thus avoid instability after installation, the dustproof box 5 is designed to prevent aggregate from jumping out of the opening at the top of the screening box 104 during the screening process, thereby avoiding impact on the nearby construction environment. At the same time, it can reduce the spread of dust in the air when screening aggregate in the screening box 104, improving the construction environment. The dustproof box 5 and the moving component 6 are designed to facilitate the disassembly and movement of the dustproof box 5, saving time and effort for personnel to move the dustproof box 5, and facilitating the cleaning and maintenance of the screening box 104.

[0022] As one implementation method in this embodiment, such as Figure 1 and Figure 2As shown, the limiting component 3 includes a straight plate 301, which is fixedly connected to the bottom end of the base plate 2. A rotating rod 302 is rotatably provided at the bottom end of the straight plate 301, and a rotating plate 303 is fixedly connected to the bottom end of the rotating rod 302. The vibration component 4 includes a connecting plate 401, and a vibration motor 402 is fixedly connected to the bottom end of the connecting plate 401. Several screw holes 202 are provided from the bottom end to the top end of the connecting plate 401 and from the bottom end of the fixed plate 201. A bolt 403 is threadedly connected between each screw hole 202 at the bottom end of the connecting plate 401 and each screw hole 202 at the bottom end of the fixed plate 201. Several limiting ports 404 are provided from the bottom end to the top end of the connecting plate 401. When the vibration motor 402 is started, due to the cooperation of the spring 103 and the telescopic rod 102, the screening box 104 can be driven to vibrate, thereby facilitating the screening of aggregates in the screening box 104.

[0023] In practice, after aligning each limiting port 404 at the bottom of the connecting plate 401 with each rotating plate 303 and straight plate 301, the plate is fitted onto the outer end of each rotating plate 303 and straight plate 301. Then, by rotating each rotating plate 303, the rotating plate 303 is rotated so that it does not coincide with the limiting port 404, but overlaps with the limiting port 404. At this time, the cooperation between the rotating plate 303 and straight plate 301 can limit the connecting plate 401, making it easy to align the screw hole 202 on the connecting plate 401 with the screw hole 202 on the fixing plate 201. Then, by threading the bolt 403 into the screw hole 202 between the connecting plate 401 and the fixing plate 201, the installation of the vibratory motor 402 can be easily completed, thus avoiding misalignment of the screw hole 202 during the installation of the vibratory motor 402, and thus avoiding instability after installation.

[0024] As one implementation method in this embodiment, such as Figure 3 and Figure 4As shown, a feed inlet 501 is provided on the side of the dustproof box 5, a handle 502 is fixedly connected to the side of the dustproof box 5, and an extension plate 503 is fixedly connected to the bottom of the dustproof box 5. A bolt 504 is threadedly connected between the side of the extension plate 503 and the side of the screening box 104. Several empty slots 505 are provided inside the dustproof box 5, and a threaded groove 506 is provided at the bottom of each empty slot 505. The moving component 6 includes a screw 601, which is threadedly connected to the threaded groove 506. A limiting plate 602 is fixedly connected to the top of the screw 601. The limiting plate 602 is located at... Inside the empty trough 505, a knob 603 is fixedly connected to the bottom end of the screw 601, a nut 604 is threadedly connected to the outer end of the screw 601, and a connecting rod 605 is fixedly connected to the bottom end of the screw 601. A caster wheel 606 is installed at the bottom end of the connecting rod 605. In practice, a dust cover is installed over the outer end of the screening box 104 to prevent aggregates from jumping out of the opening at the top of the screening box 104 during the screening process, thereby avoiding impact on the nearby construction environment. At the same time, it can reduce the spread of dust in the air when screening aggregates in the screening box 104, improving efficiency. In the construction environment, since the screw 601 is threaded into the threaded groove 506, rotating each knob 603 will move the screw 601 upwards into the empty groove 505. This upward movement of the screw 601 will then move the connecting rod 605 and the caster 606 upwards, thus lifting the caster 606 away from the ground and preventing it from affecting the vibrating motor 402's vibration screening operation on the screening box 104. When cleaning or maintenance is required inside the screening box 104, rotating the knob 603 will move the screw 601 and connecting rod 605 downwards until the caster 606 contacts the ground. At this time, the limiting plate 602 presses against the bottom of the inner cavity 505. By rotating the nut 604, the nut 604 moves up along the screw 601 to the bottom of the screening box 104. The cooperation between the nut 604 and the limiting plate 602 can improve the stability of the screw 601 and the caster 606 after they move down. By unscrewing the bolt 504 and pulling the handle 502 in conjunction with the caster 606, the dust box 5 can be temporarily moved away from the top of the screening box 104. This saves time and effort when personnel move the dust box 5, and facilitates the cleaning and maintenance of the screening box 104.

[0025] Working principle: After aligning each limiting port 404 at the bottom of the connecting plate 401 with each rotating plate 303 and straight plate 301, the connecting plate 401 is fitted onto the outer end of each rotating plate 303 and straight plate 301. By rotating each rotating plate 303, the rotating plate 303 is rotated so that it does not coincide with the limiting port 404, but overlaps with the limiting port 404. At this time, the cooperation of the rotating plate 303 and straight plate 301 can limit the connecting plate 401, making it easy to align the screw hole 202 on the connecting plate 401 with the screw hole 202 on the fixing plate 201. Then, by threading the bolt 403 into the screw hole 202 between the connecting plate 401 and the fixing plate 201, the installation of the vibrating motor 402 can be easily completed, thus avoiding misalignment of the screw hole 202 during the installation of the vibrating motor 402, and thus avoiding instability after installation.

[0026] A dust cover is installed over the outer end of the screening box 104 to prevent aggregate from jumping out of the opening at the top of the screening box 104 during the screening process, thus avoiding impact on the nearby construction environment. It also reduces dust dispersion in the air during aggregate screening, improving the construction environment. Since the screw 601 is threaded into the threaded groove 506, rotating each knob 603 moves the screw 601 upwards into the empty groove 505. This upward movement of the screw 601 moves the connecting rod 605 and the caster 606 upwards, thus lifting the caster 606 away from the ground and preventing it from interfering with the vibrating motor 402's vibration screening operation of the screening box 104. When it is necessary to clean the inside of the screening box 104... During cleaning or maintenance, rotating the knob 603 causes the screw 601 and connecting rod 605 to move downwards until the caster 606 contacts the ground. At this point, the limiting plate 602 presses against the bottom of the inner cavity 505. Rotating the nut 604 causes it to move upwards along the screw 601 to the bottom of the screening box 104. The cooperation between the nut 604 and the limiting plate 602 improves the stability of the screw 601 and caster 606 after downward movement. By unscrewing the bolt 504 and pulling the handle 502 in conjunction with the caster 606, the dust box 5 can be temporarily removed from the top of the screening box 104. This saves time and effort when moving the dust box 5 and facilitates the cleaning and maintenance of the screening box 104.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
