[0038] The present application provides a raw material screening device for screening cement, mortar and other products in the production process.

[0039] As shown in Figure 1 and Figure 2 The present application provides a raw material screening device, which comprises:

[0040] The drive 1 has an output end, and the transmission assembly 2 comprises a first transmission shaft 21 and a second transmission group 22, and the first end of the first transmission shaft 21 and the first end of the second transmission group 22 are connected with the output end respectively;

[0041] The first stirring member 3 is connected to the first region of the outer periphery of the first transmission shaft 21, and the cleaning member 4 is connected to the second region of the outer periphery of the first transmission shaft 21, and the second region is completely staggered with the first region;

[0042] A filter 5 is fixedly connected to the second end of the second transmission group 22, and can move linearly relative to the cleaning member 4 under the driving of the second end of the second transmission group 22.

[0043] Under the driving of the driving member 1, the second transmission group 22 can drive the filter 5 to move to abut against the cleaning member 4, the first transmission shaft 21 can drive the cleaning member 4 to rotate and clean the filter 5, and the first transmission shaft 21 can drive the first stirring member 3 to rotate and scatter raw materials.

[0044] The driving member 1, i.e., the power source, can be an electric motor, the output end of which is connected to the transmission assembly 2 through a shaft coupling or direct connection, and provides driving force to the transmission assembly 2.

[0045] As shown in Figure 1 , the transmission assembly 2 can include a first transmission shaft 21 and a second transmission group 22. One end of the first transmission shaft 21 is directly connected to the output end of the driving member 1, and the other end is empty or connected to other auxiliary components. The second transmission group 22 can be composed of transmission shafts, gear sets, chain and sprocket, etc., the first end of which is also connected to the output end of the driving member 1, but is separated from the first transmission shaft 21 through different transmission paths to achieve different motion characteristics. The second end of the second transmission group 22 is fixedly connected to the filter 5 to drive the filter 5 to move.

[0046] As shown in Figure 1 and Figure 3 , the first stirring member 3 can be long strip-shaped or paddle-shaped, and is connected to the first region on the outer periphery of the first transmission shaft 21 through welding, bolt connection or other fixing methods, the first region being away from the mounting position of the cleaning member 4 to ensure that the two do not interfere with each other when rotating.

[0047] As shown in Figure 1 and Figure 3 , the cleaning member 4 can be designed as a brush, a scraper or other wiping elements of soft material, and is connected to the second region on the outer periphery of the first transmission shaft 21 through a support or other structure, the second region being completely staggered with the mounting position of the first stirring member 3 to ensure that the two do not interfere with each other when rotating. The first region and the second region can be arranged to form a complete outer periphery of the first transmission shaft 21 to ensure the stirring and cleaning capabilities of the raw material screening device. The first region can also be arranged to occupy half of the complete outer periphery of the first transmission shaft 21, i.e., the second region occupies the other half of the complete outer periphery of the first transmission shaft 21.

[0048] The cleaning member 4 can be made of wear-resistant and corrosion-resistant special synthetic materials, such as polyurethane or nylon, to enhance its durability and cleaning efficiency.

[0049] As Figure 2 shown, the filter 5 can be a screen, a filter or a plate structure with a specific pore size for screening and separating different particle size components in the raw materials. Its edge is fixedly connected to the second end of the second transmission group 22 by welding, bolting or other fastening methods, which can ensure stable linear motion during transmission.

[0050] During operation, the driving member 1 is first started, the first transmission shaft 21 rotates, and the first stirring member 3 stirs the raw materials placed in the device, which helps to break up the raw material agglomerates and ensures uniform distribution of the raw materials before screening, avoiding the reduction of screening efficiency caused by raw material agglomeration.

[0051] At the same time, the second transmission group 22 drives the filter 5 to move linearly in the device, so that the filter 5 can move to a position where it abuts or contacts the cleaning member 4. At this time, the rotation of the first transmission shaft 21 drives the cleaning member 4 to rotate, and the cleaning member 4 can wipe or scrape the surface of the filter 5 during rotation, remove the residues attached thereto, and clean the clogged screen holes of the filter 5, thereby ensuring the continuous and stable screening effect.

[0052] Without cleaning, the second transmission group 22 can drive the filter 5 away from the cleaning member 4, which can avoid interference with the stirring motion of the first stirring member 3.

[0053] Among them, the second transmission group 22 can adopt gear transmission or transmission shaft group transmission, so that the linear motion of the filter 5 is more stable and the motion distance is precisely controlled, thereby improving the cleaning effect.

[0057] Optionally, the second transmission group 22 comprises a movable shaft 221 and a connecting shaft 222, one end of the movable shaft 221 is connected with one end of the connecting shaft 222, the other end of the movable shaft 221 is connected with the output end, and the other end of the connecting shaft 222 is fixedly connected with the side wall of the filtering element 5.

[0058] Under the driving of the driving element 1, the movable shaft 221 can rotate and drive the connecting shaft 222 to move linearly, so that the filtering element 5 can move to abut against the cleaning element 4.

[0059] As shown in Figure 1 and Figure 2 The second transmission group 22 can comprise two transmission shafts, i.e., the movable shaft 221 and the connecting shaft 222, which are used to transmit the driving force of the driving element 1 to the filtering element 5 and drive the filtering element 5 to move to abut against the cleaning element 4 through the other end of the connecting shaft 222, so that the cleaning element 4 can wipe or scrape the surface of the filtering element 5 during rotation, remove the residues attached thereto, and clean the screen holes of the clogged filtering element 5, thereby ensuring the continuous and stable screening effect.

[0060] Optionally, the second transmission group 22 further comprises a limiting ring 223, the limiting ring 223 is fixedly connected to the housing 6, and part of the connecting shaft 222 is arranged in the limiting ring 223, so that the connecting shaft 222 can move linearly along the axial direction of the limiting ring 223.

[0061] As shown in Figure 2 The limiting ring 223 is fixedly connected to the housing 6, so as to limit the movement of the connecting shaft 222 through the limiting ring 223. Specifically, part of the connecting shaft 222 is arranged in the limiting ring 223, so that under the driving of the movable shaft 221, the connecting shaft 222 located in the limiting ring 223 can only move linearly along the axial direction of the limiting ring 223 and drive the filtering element 5 to also move linearly to abut against the cleaning element 4.

[0062] The axial direction of the limiting ring 223 can be set as the vertical direction, so that the linear movement direction of the filtering element 5 driven by the connecting shaft 222 is also the vertical direction, which can ensure that the filtering element 5 always remains horizontal during movement, thereby ensuring the screening effect.

[0063] Optionally, the connecting shaft 222 comprises a first segment 2221 and a second segment 2222 connected with each other, the first segment 2221 is arranged in the limiting ring 223 and connected with the movable shaft 221, and the second segment 2222 is fixedly connected with the side wall of the filtering element 5.

[0065] Optionally, the first aggregate bin 61 is in a self-top-to-bottom tapered shape, so as to facilitate the collection of raw materials screened by the filter element 5.

[0067] Under the driving of the driving element 1, the first transmission shaft 21 can drive the cleaning element 4 to rotate, so that the cleaning heads can clean the filter holes.

[0068] As shown, Figure 3 the plurality of cleaning heads are arranged in an array and correspond to the filter holes on the filter element 5, so that when the first transmission shaft 21 rotates, the cleaning element 4 can also be driven to rotate, so that the plurality of cleaning heads can clean the corresponding filter holes, so as to avoid the clogging of the filter holes of the filter element 5, thereby ensuring the continuous and stable screening effect.

[0069] Optionally, the first stirring element 3 includes a plurality of stirring blades, and the plurality of stirring blades are uniformly connected to the first region. When the first transmission shaft 21 rotates, the plurality of stirring blades can be driven to rotate together to stir the raw materials placed in the device, which helps to break up the raw material agglomerates and ensures that the raw materials are uniformly distributed before screening, and also avoids the reduction of screening efficiency caused by the agglomeration of raw materials.
