Description

Automatic cleaning device for screen mesh

Technical Field

The utility model relates to a grain screening technical field specifically indicates an automatic cleaning device of screen cloth.

Background

Grain is put in storage because impurity, grain outer brown rice etc. exceed standard, need clear up in advance, often use vibration cleaning sieve equipment to let particulate matters such as broken grain, grain outer brown rice in the grain that flows go out by the sieve mesh sieve of screen cloth, and remaining grain gets into in the storage after the sifter flows out. After the equipment is used for a long time, the sieve pores can be plugged by particles in part of grains, so that the impurity removal efficiency of the equipment is reduced, and the equipment must be stopped for cleaning. Because the screen cloth is fixed inside equipment, consequently need stop to dismantle equipment shell and pull down the screen cloth again, with the equipment of entering after scraper and the clearance of steel brush, this not only influences grain speed of warehousing, dismouting, clearance screen cloth are wasted time and energy moreover.

Disclosure of Invention

The utility model provides an automatic cleaning device of screen cloth to solve the above-mentioned problem that exists among the prior art.

The utility model adopts the following technical scheme:

the automatic cleaning device for the screen comprises a roller, wherein the roller is movably arranged above the screen, and a plurality of bulges which are in one-to-one correspondence with screen holes of the screen are arranged on the circumferential surface of the roller.

Further, the protrusions are cones or conical round tables.

Further, still include the scraper, this scraper is movably set up in the screen cloth top for cut off the particulate matter of card in the aperture.

Furthermore, a sliding mechanism mainly composed of a sliding block and a sliding rail is arranged on each of the left side and the right side of the screen, the left end and the right end of the roller are respectively and rotatably arranged on the two sliding blocks, and the left end and the right end of the scraper are respectively and fixedly arranged on the two sliding blocks.

Furthermore, the device also comprises a push-pull rod which is fixedly connected with at least one sliding block.

From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

one of the two, the utility model discloses a cylinder, the cylinder is movably to be set up in the top of screen cloth, and the periphery of cylinder is equipped with a plurality of sieve mesh matched with archs with the screen cloth. When the roller rolls, the protrusions on the surface can automatically extrude particles in the sieve holes, so that the purpose of cleaning the sieve is achieved. It can be seen that the utility model discloses can clear up the screen cloth automatically, and need not shut down, tear the machine open, can solve the operation difficulty of artifical clearance, the problem that wastes time and energy, have the efficiency height, advantage such as automatic strong.

And secondly, the utility model discloses a scraper, the scraper is movably to be set up in the screen cloth top for cut off the particulate matter of card in the sieve mesh. Utilize the scraper to carry out cutting processing earlier to the particulate matter in the sieve mesh, make the particulate matter after the cutting have a better roughness with the up end of screen cloth, be favorable to the arch of cylinder to extrude the particulate matter from the sieve mesh.

Drawings

Fig. 2 is a partially enlarged view of a in fig. 1.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

Referring to fig. 1 and 2, the automatic cleaning device for the screen is provided with a sliding mechanism 1 mainly composed of a sliding block 11 and a sliding rail 12 on each of the left and right sides of the screen 3. The upper part of the screen 3 is provided with a roller 2 extending to the left and right sides of the screen 3, the left and right ends of the roller 2 are respectively and rotatably arranged on two sliding blocks 11, and the roller 2 can move back and forth through a sliding mechanism 1. The circumferential surface of the drum 2 is provided with a plurality of projections 21 which are arranged corresponding to the screen holes 31 of the screen 3 one by one. The bulge 21 is a cone or a conical round table, and the end with larger diameter of the bulge 21 is connected with the roller 2. Since the protrusions 21 can be engaged with the holes 31, the granules in the holes 31 can be extruded out, and the protrusions 21 can be inserted into the holes 31. When the drum 2 moves forward, the protrusions 21 inserted into the mesh openings 31 are subjected to a backward force applied thereto by the screen 3, and the drum 2 can rotate by itself while moving forward and backward.

Referring to fig. 1 and 2, a scraper 4 extending to the left and right sides of the screen 3 is disposed above the screen 3, and the left and right ends of the scraper 4 are respectively fixed to two sliders 11 through two connecting members 5. The scraper 4 can move back and forth through the sliding mechanism 1 and is used for cutting off the particles clamped in the sieve pores 31. The scraper blades 4 may optionally be arranged parallel to the screening surface and as close as possible to the screening surface.

Referring to fig. 1 and 2, a push-pull rod 6 is provided at one side of the screen 3, and the push-pull rod 6 is fixedly connected to at least one sliding block 11. The sliding block 11 on the sliding rail 12 is pushed by the push-pull rod 6 to drive the roller 2 rotationally connected with the sliding block 11 to move forward, and the scraper 4 fixedly connected with the sliding block 11 is driven to move forward. Alternatively, a motor may be used to power the slider 11.

The utility model discloses in, cylinder 2 and scraper 4 can choose for use different slide rail 12 and slider 11, also can choose for use same slide rail 12 and slider 11, also can only choose for use cylinder 2 to carry out work.

The utility model discloses a theory of operation: scraper 4 passes through slide mechanism 1 and moves forward and cuts off the particulate matter of card in sieve mesh 31, and cylinder 2 passes through slide mechanism 1 and moves forward simultaneously and rolls, and arch 21 on the cylinder 2 can cooperate with sieve mesh 31 during the roll, extrudes the particulate matter in the sieve mesh 31.

The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
