[0002] Shale brick is a brick made of shale material. Shale is a sedimentary rock with specific structure and properties. After processing and manufacturing, it can be used in the construction field. Shale bricks usually have high strength, durability and fire resistance. They are suitable for various construction projects, especially in situations where compression and wear resistance are required. The surface of shale bricks is usually treated and can have different colors and textures to meet different decorative needs.

[0003] In the processing of shale bricks, it is often necessary to screen the raw materials through a screening device to ensure the quality of the final product. The current screening device is usually composed of a screen and a chassis. The screen is used to dry out large particles of raw materials. However, there are the following problems, that is, when the raw materials fall onto the screen, they cannot be quickly and evenly dispersed, resulting in low screening effect and efficiency. In addition, fine particles are often attached to the surface of large particles of raw materials, resulting in incomplete screening. In addition, the speed at which the screened raw materials are discharged from the chassis is slow and easy to clog, which seriously affects production efficiency.

[0004] Therefore, a screening device for shale brick production and processing is proposed to solve the above problems. Utility Model Content

[0026] Preferably, as another embodiment of the utility model, the conveying mechanism 4 includes an outlet 41, a spiral blade 42, a transmission shaft 43 and a motor 44.

The front of the cylinder body 1 is provided with an output shaft and a motor 44 coaxially connected to the front end of the transmission shaft 43.

[0027] In this embodiment, the motor 44 outputs torque and drives the transmission shaft 43 to rotate, and the spiral blade 42 on the transmission shaft 43 rotates accordingly. During this process, the rotating spiral blade 42 will generate an axial propulsion force along the transmission shaft 43 to push the raw materials inside the box body 2 backwards, and then discharge them from the outlet 41 on the box body 2.

[0029] In this embodiment, the dual-axis motor 85 can drive the cam 83 and the horizontal axis 84 to rotate. During this process, the eccentric parts of the two cams 83 are connected by a connecting rod 82 and a pulling rod 81, so that the two cams 83 pull the pulling rod 81 to move back and forth through the connecting rod 82, and the other end of the pulling rod 81 will vertically reciprocate the screen plate 5. During this process, when the screen plate 5 moves downward, it will continuously squeeze the spring 63 along the limit rod 62. When the screen plate 5 moves upward, the spring 63 drives the screen plate 5 to move upward under the action of elastic force, that is, to return to its original position, so that the screen plate 5 can shake steadily in the vertical direction, and the raw materials falling on the surface of the screen plate 5 can be quickly and evenly dispersed.

[0031] In this embodiment, the motor 2 91 can drive the vertical shaft 92 to rotate, and the spiral blade 2 93 thereon will also rotate accordingly, and generate an axial and downward propulsion force along the direction of the vertical shaft 92, that is, the vertical direction, thereby quickly discharging the raw materials from the cylinder 94 out of the equipment to reduce material stacking and avoid blockage. The frame 11 is connected to the cylinder 1 and the lower end is lower than the cylinder 94, which can support the equipment and keep the equipment in a stable state.

[0032] Working principle: the material can be poured into the sieve plates 5 on both sides through the two feed ports 10, and the double-axis motor 85 can drive the cam 83 and the horizontal shaft 84 to rotate. During this process, the connecting rod 82 on the eccentric part of the cam 83 will pull the pull rod 81 to move back and forth, and the other end of the pull rod 81 will vertically reciprocate and pull the sieve plate 5. During this process, when the sieve plate 5 moves down, it will continuously squeeze the spring 63 along the limit rod 62. When the sieve plate 5 moves up, the spring 63 will drive the sieve plate 5 to move up, that is, return to its original position, so that the sieve plate 5 can shake steadily in the vertical direction, and the raw materials falling on the surface of the sieve plate 5 can be quickly and evenly dispersed, thereby maximizing the use of the screening area, thereby improving the screening effect and screening efficiency, and the large particles screened out are The material will enter the box body 2. At the same time, the motor 44 drives the transmission shaft 43 and the spiral blade 42 to rotate, thereby generating an axial propulsion force to push the raw materials inside the box body 2 backwards and then discharge them from the outlet 41 on the box body 2. In this process, the surfaces of the large particles of raw materials will rub against each other, and the surfaces of the large particles of raw materials will generate friction with the inner wall of the box body 2 and the surface of the spiral blade 42. The fine particles on the surface of the large particles of raw materials will be separated due to friction and discharged from the through hole 3, so that the screening is more thorough, further improving the screening effect. The motor 91 can drive the vertical shaft 92 and the spiral blade 93 to rotate, generating an axial and downward propulsion force, thereby quickly discharging the raw materials from the cylinder 94 out of the equipment.
