[0025] Specifically, in the actual use of a housing construction waste treatment device provided by an embodiment of the utility model, several evenly arranged fixed screen rollers 2 and moving screen rollers 3 rotate simultaneously. Since the rotation directions of the fixed screen rollers 2 and the moving screen rollers 3 are opposite, and the fixed screen rollers 2 and the moving screen rollers 3 are alternately distributed inside the screening frame 1, such a design can make the rotation tangent directions of the facing surfaces of two adjacent fixed screen rollers 2 and the moving screen rollers 3 consistent, and the leak-proof component 4 is arranged on the area where the rotation tangent directions of the facing surfaces of two adjacent fixed screen rollers 2 and the moving screen roller 3 are both downward. With the cooperation of the leak-proof component 4, it can be ensured that the upward part of the rotation tangent of the facing surfaces of the adjacent fixed screen rollers 2 and the moving screen roller 3 can be used for actual screening, assisting in pushing out larger waste materials, so that they move under the action of vibration to leave the equipment, thereby effectively reducing the probability of blockage, and smaller waste materials can fall from the screening gap not covered with the leak-proof component 4, thereby realizing the screening of the waste materials.

Specifically, due to the setting of the connecting rod 10, the connecting rod 10 can be driven to move left and right by the rotating wheel 14 and the adjusting rod 12 in cooperation with the fixing block 13 and the connecting cavity 11, which can drive a plurality of connecting sleeves 31 to move synchronously, and then make a plurality of moving screen roller bodies 33 move synchronously, so that the distance between them and the adjacent fixed screen rollers 2 can be changed at the same time, thereby achieving the effect of adjusting the screening specifications.

[0035] For further explanation, the embodiment of the utility model also provides the working principle and use process of the housing construction waste treatment device:

[0036] The screening frame 1 is integrally mounted on the vibration frame, and the construction waste is dumped on the top of the equipment. During the continuous vibration process, the construction waste moves along the fixed screen roller 2, the moving screen roller 3 and the top of the leak-proof component 4, and the smallest waste is continuously screened out. At the same time, the larger waste is rotated out by the adjacent fixed screen roller 2 and the moving screen roller 3, and gradually moves downstream through the leak-proof component 4, and finally leaves the screening frame 1;

[0037] After use, the rotating wheel 14 can drive the adjusting rod 12 to rotate under the restriction of the fixed block 13, that is, under the cooperation of the connecting cavity 11, the connecting rod 10 drives the plurality of connecting sleeves 31 to move simultaneously, thereby driving the plurality of movable screen roller bodies 33 to move simultaneously, so that the distance between the movable screen rollers 33 and the adjacent fixed screen rollers 2 changes, so that the waste stuck between the two can be removed; at the same time, the size of the waste suitable for screening can be adjusted;

[0038] Due to the change in the distance between adjacent fixed screen rollers 2 and movable screen roller bodies 33, the first scraper 41 and the second scraper 42 can always fit tightly against the outer surfaces of the fixed screen roller 2 and the movable screen roller body 33 respectively under the action of the elastic force of the positioning spring 43, thereby preventing crushed materials from falling and affecting the adjusted screening accuracy.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
