as shown in fig. 2 and 3, each layer of screening plate 200 includes a main plate 210 and two side plates 220 disposed at two sides of the main plate 210, the middle of the main plate 210 is provided with a screening hole 211, two sides of the main plate 210 are respectively provided with a mounting groove 212, and the side plates 220 are slidably inserted into the mounting grooves 212; the side plate 220 is divided into an alignment plate 221 and a connection plate 222 along the direction of two sides of the main plate 210, the top wall of the connection plate 222 is sunken relative to the top wall of the alignment plate 221 and forms a step 223, the bottom wall of the connection plate 222 is flush with the bottom wall of the alignment plate 221, the alignment plate 221 can slide out of the mounting groove 212 and enables the top wall of the alignment plate 221 to be flush with the top wall of the main plate 210, and the step 223 is butted with the two side parts of the main plate 210;
the screening power mechanism 700 is disposed at one side of the housing 100 where the material loading bin 110 is disposed and is in driving connection with the higher end of the screening plate 200, the screening power mechanism 700 can drive the screening plate 200 to move back and forth along the directions of the two sides of the main plate 210, and the alignment plate 221 can movably pass through the housing 100.
With reference to fig. 1 and 2, the sieving power mechanism 700 drives the sieving plate 200 to move back and forth along the direction of connecting the two side plates 220, so as to leave the materials which are arranged on the sieving plate 200 and are larger than the sieving holes 211 on the sieving plate 200, and the materials which are smaller than the sieving holes 211 fall to the next sieving plate 200 through the sieving holes 211, so that the multiple sieving plates 200 can sieve out the materials with different sizes and discharge the materials through the discharging bins 120 for use.
Referring to fig. 2 and 3, in order to facilitate the installation and removal of the screening plate 200, the side plates 220 on both sides of the main plate 210 can be retracted into the installation grooves 212, and when in use, the two side plates 220 are driven out of the installation grooves 212. After the side plate 220 slides out of the mounting groove 212, the connecting plate 222 is still placed in the mounting groove 212 to complete the connection between the main plate 210 and the side plate 220, the alignment plate 221 slides out of the mounting groove 212, because of the step 223, the step 223 is located outside the mounting groove 212, and the thickness of the connecting plate 222 is smaller than that of the alignment plate 221, so that the connecting plate 222 and the alignment plate 221 both move towards the surface of the main plate 210 along the thickness direction of the main plate 210 until the top wall of the alignment plate 221 is aligned with the main plate 210, and the step 223 is attached to the two side portions of the main plate 210 to complete the expansion of the side plate 220. The top wall of the alignment plate 221 needs to be flush with the top wall of the main board 210 after being unfolded, so as to avoid that the thickness of the alignment plate 221 is smaller than that of the main board 210, which may cause screening materials to fall between the two sides of the main board 210 and the inner wall of the housing 100, and cause obstruction to screening, that is, after the step platform 223 is attached to the side portions of the two sides of the main board 210, the top wall of the alignment plate 221 should be flush with the top wall of the main board 210, or protrude from the top wall of the main board.
With reference to fig. 1 and 2, after the side plate 220 is retracted, the width of the main plate 210 is similar to the inner width of the housing 100, so that the housing 100 can be smoothly taken out, and the side plate 220 is extended to ensure smooth screening, thereby facilitating the installation and replacement of the screening plate 200 through the arrangement of the screening plate 200.
