Detailed implementation mode

[0022] As Figures 1 - 4 shown, the utility model provides a technical solution: a building material screening device, including a tank body 1, a feed inlet 2 is arranged on the tank body 1, a motor 3 is fixedly installed on the tank body 1, a rotating rod 4 is fixedly connected to the output end of the motor 3, a stirring rod 5 is fixedly installed on the outer wall of the rotating rod 4, and by starting the motor 3, the stirring rod 5 on the outer wall of the rotating rod 4 can push the waste on the screen 6 flat. A screen 6 is fixedly installed on the inner wall of the tank body 1, the stirring rod 5 is located above the screen 6, a blanking mechanism 7 is arranged inside the tank body 1, and a vibration mechanism 8 is arranged inside the tank body 1.

[0023] In this embodiment, a blanking mechanism 7 is arranged inside the tank body 1. By alternately blocking the waste by the first baffle 76 and the second baffle 78 in the blanking mechanism 7 inside the feed inlet 2, the feed inlet 2 can feed intermittently into the tank body 1, preventing too much waste from accumulating on the screen 6 and resulting in a low screening rate.

[0024] In this embodiment, a vibration mechanism 8 is arranged inside the tank body 1. By driving the impact block 82 at the end to move left and right continuously to impact the impact rod 83 by the fixed rod 81 in the vibration mechanism 8, the impact rod 83 can drive the screen 6 to vibrate. At the same time, by pushing the materials on the screen 6 flat by the stirring rod 5, the screening of the waste by the screen 6 can be accelerated.

[0025] The above-mentioned blanking mechanism 7 includes a fixed frame 71, which is fixedly installed on the inner wall of the tank body 1. A pressing rod 72 penetrates through the inside of the fixed frame 71. A return spring 73 is sleeved on the outer wall of the pressing rod 72. One end of the return spring 73 is fixedly connected to the outer wall of the pressing rod 72, and the other end of the return spring 73 is fixedly connected to the inner wall of the fixed frame 71. The elastic force of the return spring 73 can enable the pressing rod 72 to drive the first baffle 76 and the second baffle 78 to reset. A convex rod 74 is fixedly installed on the outer wall of the pressing rod 72, and a first connecting rod 75 is fixedly installed at the end of the pressing rod 72. A first baffle 76 is fixedly installed at the end of the first connecting rod 75. The end of the first baffle 76 penetrates through the inside of the feed inlet 2. The pressing rod 72 is fixedly connected to one end of a second connecting rod 77, and a second baffle 78 is fixedly installed at the other end of the second connecting rod 77. The second baffle 78 penetrates through the inside of the feed inlet 2. By alternately blocking the waste inside the feed inlet 2 with the first baffle 76 and the second baffle 78, the feed inlet 2 can feed intermittently into the tank body 1. A sleeve block 79 is fixedly sleeved on the outer wall of the rotating rod 4, and a vertical rod 710 is fixedly installed on the bottom wall of the sleeve block 79. The vertical rod 710 is located on the side of the convex rod 74. By driving the vertical rod 710 on the bottom wall of the sleeve block 79 to rotate by the rotating rod 4 and extruding the outer wall of the convex rod 74, the convex rod 74 can be driven to drive the pressing rod 72 to move to the right.

[0026] The above-mentioned vibration mechanism 8 includes a fixed rod 81, which is fixedly installed at the end of the pressing rod 72. An impact block 82 is fixedly installed at the end of the fixed rod 81. An impact rod 83 is fixedly installed on the outer wall of the screen 6. The impact rod 83 is located on the side of the impact block 82. By driving the impact block 82 at the end of the fixed rod 81 by the pressing rod 72 to impact the outer wall of the impact rod 83, the impact rod 83 can be driven to drive the screen 6 to vibrate and screen, thereby accelerating the screening efficiency.

[0027] In this embodiment, first, a suitable power supply is applied to the motor 3. By starting the motor 3, the stirring rod 5 on the outer wall of the rotating rod 4 is driven to stir the waste materials on the screen 6. At the same time, the rotating rod 4 drives the vertical rod 710 on the bottom wall of the sleeve block 79 to rotate. By the rotation of the vertical rod 710, the outer wall of the convex rod 74 is extruded. Then, the convex rod 74 drives the extrusion rod 72 to move to the right. At this time, the extrusion rod 72 drives the second baffle 78 at the end of the second connecting rod 77 to move out of the inside of the feed inlet 2 to the right. At the same time, the extrusion rod 72 drives the first baffle 76 at the end of the first connecting rod 75 to move into the inside of the feed inlet 2 to block the materials. Then, a part of the materials inside the feed inlet 2 fall onto the screen 6 for screening. Then, by the elastic force of the return spring 73, the extrusion rod 72 drives the first baffle 76 and the second baffle 78 to reset. The second baffle 78 blocks the materials inside the feed inlet 2 to stop the feeding. Thus, the materials inside the feed inlet 2 can be fed intermittently. At the same time, the extrusion rod 72 drives the impact block 82 at the end of the fixed rod 81 to move left and right continuously to impact the impact rod 83, so that the impact rod 83 drives the screen 6 to vibrate. By the vibration of the screen 6, the screening efficiency is increased. Thus, the screening work of the waste materials is completed.

[0028] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements without departing from the spirit of the present invention are within the protection scope of the present invention.
