Description

Rice polishing machine dust removal mechanism

Technical Field

The utility model belongs to the technical field of the grain processing technique and specifically relates to indicate rice burnishing machine dust removal mechanism.

Background

The rice of current rice processing enterprise is when the polishing, and the rice that the burnishing machine goes out rice mouth and comes out all directly falls to leading in the rice fill to derive, and this kind of mode, rice are at the in-process that falls down, and the bran dust in the rice can fly away in the workshop along with the wind, causes the workshop raise dust big.

Disclosure of Invention

The utility model aims to overcome the not enough of prior art, provide a rice polishing machine dust removal mechanism rational in infrastructure, that dust removal effect is good.

In order to achieve the above object, the present invention provides a technical solution: rice polishing machine dust removal mechanism, it is including the suction hood, suction hood bottom opening forms the dust absorption mouth, the suction hood is squarely, its front side lateral wall from bottom to top contracts gradually and forms leads the dirt face, the suction hood top is connected with the dust absorption pipe, the dust absorption pipe is connected with outside air exhauster, movable mounting has the rice filter screen in the suction hood, suction hood rear side inside wall middle part is fixed with the hinge piece, the activity is articulated on the hinge piece has the filter screen picture peg, filter screen picture peg one end is articulated with the hinge piece, the recess forms the slot in the filter screen picture peg other end indent, it is equipped with the shell fragment of "3" font to lead the dirt face inside wall middle part, the activity cartridge of one of them end edge of rice filter screen is in the slot, rice filter screen other end edge.

The top of the elastic sheet is fixedly connected with the middle part of the inner side wall of the dust guide surface, the lower part of the elastic sheet is suspended, the protruding part on the upper part of the elastic sheet is larger than the protruding part on the lower part, and a middle groove is arranged between the two protruding parts.

The rice filter screen is made of a metal grid plate.

The rice filter screen is made of a metal plate, a filter hole penetrating through the metal plate from top to bottom is formed in the metal plate, and a pull pin is fixed on one side of the bottom of the rice filter screen.

After the technical scheme is adopted, the utility model can be directly and additionally arranged above the rice polishing outlet of the prior art, the meshes of the metal mesh and the apertures of the filter holes are smaller than the transverse particle diameter of the rice, the rice is prevented from being sucked out, the external exhaust fan exhausts air, the rice falling from the outlet is dedusted by the dust suction pipe and the dust hood, the rice filter screen adopts a movable plug-in type, the cleaning and the replacement are convenient, the rice filter screen at one end of the pull pin is arranged in the spring piece, when the rice filter screen is replaced, the hand enters from the dust suction port, the pull pin is pulled down, the rice filter screen is withdrawn from the spring piece, then the rice filter screen is continuously pulled, the rice filter screen is withdrawn from the slot, after the cleaning is finished, or when the new rice filter screen is replaced, the rice filter screen is firstly put into from the dust suction port in an inclined way, one end of the rice filter screen is inserted into the slot, then the pull pin is, the rice filter screen edge card of this end go into the middle recess of shell fragment can, rational in infrastructure after this scheme of adoption, dust removal effect are good.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention.

Detailed Description

The present invention will be further explained with reference to the drawings, and the preferred embodiment of the present invention is: referring to the attached drawing 1, the rice polishing machine dust removal mechanism of this embodiment includes suction hood 3, the 3 bottom openings of suction hood form the dust absorption mouth, suction hood 3 is squarely, its front side lateral wall from bottom to top contracts gradually and forms leads dirt face 12, suction hood 3 top is connected with dust absorption pipe 4, dust absorption pipe 4 is connected with outside air exhauster, movable mounting has rice filter screen 11 in the suction hood 3, rice filter screen 11 adopts the metal grid board to make, rice filter screen 11 adopts the metal sheet to make, it has the filtration hole that runs through from top to bottom to open on the metal sheet, rice filter screen 11 bottom one side is fixed with the broach. The middle part of the inner side wall of the rear side of the dust hood 3 is fixed with a hinge block 13, the hinge block 13 is movably hinged with a filter screen inserting plate 14, one end of the filter screen inserting plate 14 is hinged with the hinge block 13, the other end of the filter screen inserting plate 14 is inwards concave to form a slot 15, the middle part of the inner side wall of the dust guide surface 12 is provided with a spring plate 16 in a shape like a '3', the edge of one end of the rice filter screen 11 is movably inserted into the slot 15, the edge of the other end of the rice filter screen 11 is clamped in a middle groove of the spring plate 16, the top of the spring plate 16 is fixedly connected with the middle part of the inner side wall of the dust guide surface 12. The embodiment can be directly and additionally arranged above the existing rice polishing rice outlet, the meshes of the metal meshes and the apertures of the filter holes are smaller than the transverse particle size of the rice, so that the rice is prevented from being sucked out, an external exhaust fan exhausts air, the rice falling from the rice outlet is dedusted by the dust suction pipe and the dust hood, the rice filter screen is movably inserted and is convenient to clean and replace, the rice filter screen at one end of the pull pin is arranged in the elastic sheet, when the rice filter screen is replaced, a hand enters the dust suction port, the pull pin is pulled downwards to withdraw the rice filter screen from the elastic sheet, then the rice filter screen is continuously pulled to withdraw the rice filter screen from the slot, after the cleaning is finished or when a new rice filter screen is replaced, the rice filter screen is obliquely put into the dust suction port firstly, one end of the rice filter screen is inserted into the slot, then the pull pin is held by hand, the rice filter screen at one end of, the rice filter screen edge card of this end go into the middle recess of shell fragment can, rational in infrastructure, dust removal effect after the adoption this embodiment are good.
