Description
Technical field
The utility model relates to screening plant technical field, is specifically related to a kind of screening machine.
Background technology
Screening machine is the relative motion utilizing bulk granular material and compass screen surface, makes partial particulate through sieve aperture, the materials such as sand, gravel, rubble is divided into the vibration screening machinery equipment of different stage by granular size.Existing screening machine mainly exists and easily gets stuck and the shortcoming of sizing, when occur getting stuck and sizing time need manually to clear up, not only waste time and energy, also have impact on normal production; Further, existing screening machine only has the effect of screening, cannot carry out second-time breakage to material.
Utility model content
The technical problems to be solved in the utility model overcomes the deficiency that prior art exists, and provides one to realize automatic cleaning, structure is simple, cost is low, the screening machine of time saving and energy saving, efficient energy-saving.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of screening machine, the driven unit comprising frame, be installed in the screen drum in frame and be installed in for driving screen drum to rotate in frame, described frame is provided with the cleaning brush for cleaning the material on screen drum, and described cleaning brush is installed on the top of screen drum and is affixed with the outer wall of screen drum.
As further improvement of the utility model:
Described cleaning brush is fixed in frame by a mounting bracket, and cleaning brush extends to the other end from one end of screen drum.
Described cleaning brush is positioned at directly over screen drum.
The medial surface of described screen drum is also provided with multiple projection.
Described multiple projection is fixed in the medial surface of screen drum in non-uniform Distribution mode.
Described projection is sharp tooth.
Described driven unit comprises and is installed in motor in frame and reduction box, and described motor is connected with the rotating shaft of screen drum by reduction box.
Compared with prior art, the utility model has the advantage of: screening machine of the present utility model is by installing cleaning brush fixing above screen drum, along with the rotation of screen drum, cleaning brush can clean the material blocking or stick on screen drum, thus ensure normally carrying out of screening work, and the cleaning brush be fixedly installed relies on the rotation of screen drum to realize automatic cleaning, do not need to arrange power in addition again, have that structure is simple, cost is low, the advantage of time saving and energy saving, efficient energy-saving, this screening machine is particularly useful for the screening of wet soft powder lump material.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, screening machine of the present utility model, the driven unit comprising frame 1, be installed in the screen drum 2 in frame 1 and be installed in for driving screen drum 2 to rotate in frame 1, driven unit comprises and is installed in motor 5 in frame 1 and reduction box 6, motor 5 is connected with the rotating shaft 22 of screen drum 2 by reduction box 6, screen drum 2 can be driven to rotate and carry out screening work.Frame 1 is provided with the cleaning brush 3 for cleaning the material on screen drum 2, cleaning brush 3 is installed on the top of screen drum 2 and is affixed with the outer wall of screen drum 2, and, cleaning brush 3 extends to the other end from one end of screen drum 2, can clean whole screen drum 2, this cleaning brush 3 can adopt nylon bristle or the existing hairbrush made by other materials.The installation of cleaning brush 3 specifically, frame 1 is installed with a mounting bracket 4, and cleaning brush 3 is installed on this mounting bracket 4.Along with the rotation of screen drum 2, the material that cleaning brush 3 pairs of screen drums 2 block or adhere to cleans, thus ensure normally carrying out of screening work, because this cleaning brush 3 relies on the rotation of screen drum 2 to realize automatic cleaning, do not need to arrange power in addition again, have that structure is simple, cost is low, the advantage of time saving and energy saving, efficient energy-saving, be particularly useful for the screening of wet soft powder lump material.
In the present embodiment, cleaning brush 3 is positioned at directly over screen drum 2, namely also cleaning brush 3 is affixed with screen drum 2 outer wall topmost and cleans, because the material blocking or stick on screen drum 2 can drop by moving to bottom in process topmost gradually with screen drum 2, when moving to position, screen drum 2 the top, the material blocking or stick on screen drum 2 is minimum, cleaning brush 3 cleans at this place, not only can reduce material scavenging amount, extend cleaning brush 3 service life, also make cleaning better effects if simultaneously.
In the present embodiment, the medial surface of screen drum 2 is also provided with multiple protruding 21, and protruding 21 in sharp tooth, and rotate in the process of screening materials carrying at screen drum 2, thick block material is constantly clashed into by the projection 21 of sharp tooth, forms second-time breakage, can increase the quantum of output of fine granular materials.The multiple protruding 21 preferred medial surfaces being fixed in screen drum 2 in non-uniform Distribution mode are also multiple protruding 21 is irregular distribution, can improve the crushing effect to material like this.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment.For those skilled in the art, do not departing from the improvement that obtains under the utility model technical conceive prerequisite and conversion also should be considered as protection domain of the present utility model.
