Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vibrating screens for construction, in particular to a vibrating screen. Background Art
[0002] In the construction industry, a large amount of sand is needed to build roads, bridges, and houses. Pure soil or sand-soil mixtures can be used to fill roadbeds and low-lying areas of houses. Pure sandy materials can be used to mix cement and other materials for pouring concrete, painting walls, etc. Sand is usually dug from rivers or mountains and stored in raw material factories or construction sites for use. In the process of digging and storing sand, there are many lumps in the sand, and sometimes the sand is mixed with branches, white garbage and other debris. This kind of sand cannot be used directly and needs to be screened with a vibrating screen before use. The vibrating screen is a commonly used equipment in the construction industry. It is mainly used to screen sand raw materials for construction and screen out debris in the sand to improve the purity of the sand and ensure the quality of the building. Different construction processes require sand of different coarseness and fineness, and vibrating screens are also needed for screening.
[0003] At present, most of the vibrating screens on the market only have the function of screening the coarseness and fineness of sand. They cannot break up larger pieces of sand and cannot be fully screened. The sand blocks need to be screened out, handled separately, and then broken up and put into the vibrating screen for screening again. The process is complicated and time-consuming. In addition, large pieces of sand falling on the vibrating screen may easily damage the vibrating screen and affect its service life. Secondly, branches, white garbage and other debris mixed in the sand will be mixed in the coarse material, which cannot be separated by the current vibrating screen and can only be picked out manually by workers, which wastes time. If not handled cleanly, it may easily affect the quality of the building. Utility Model Content
[0004] The utility model aims to provide a vibrating screen, which can break up larger pieces of sand and soil, achieve full separation, and extend the service life of the vibrating screen. At the same time, it can also separate the sundries mixed in the sand and soil, and improve the purity of the sand and soil.

[0013] In summary, the utility model has the following beneficial effects:
[0014] 1. A breaking mechanism is provided above the screen, and the breaking mechanism is provided with a breaking rod and a breaking hammer. The breaking mechanism rotates counterclockwise under the drive of the rotating motor, which is opposite to the moving direction of the sand. When the sand falls from above the screen, the breaking rod and the breaking hammer fall at an angle of about 90 degrees to the upper surface of the screen, breaking up the larger spherical or blocky sand on the screen to achieve a better screening effect;

[0016] 3. A debris removal mechanism is provided above the screen. When white garbage, long branches and other debris mixed in the sand pass through the debris removal mechanism, the rake teeth will intercept the debris and separate it from the sand. When a lot of debris accumulates on the rake teeth, under the action of the driving force of the sand above, the debris will gradually rise along the arc-shaped rake teeth, cross the fixed axis, enter the debris removal box, and be discharged through the debris removal port to prevent the debris from being mixed in the construction raw materials and affecting the construction quality.
