Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, specifically to a grain processing fine filtration device. Background Technology

[0002] Grains are the main source of energy for the human body. In the grain processing process, the raw grains are usually crushed to remove their outer skin and husk. During the processing, they need to be finely filtered to obtain purer whole grain products.

[0003] Existing grain fine filtration devices have simple structures and relatively simple forms. When filtering, all the grain is put into the feed box, which causes too much grain to enter the filter screen and cause blockage. In view of this, we propose a grain processing fine filtration device. Utility Model Content

[0013] Compared with the prior art, this utility model provides a grain processing fine filtration device, which has the following beneficial effects:

[0014] 1. This grain processing fine filtration device, by setting up a material limiting component, when the motor starts, drives the first rotating shaft to rotate, which in turn drives the first and second pulleys to rotate, which in turn drives the second rotating shaft to rotate, which in turn drives the cam to press against the stop rod. When the cam presses against the stop rod, it drives the material limiting plate to move outward, and when the cam leaves the stop rod, it drives the material limiting plate to move inward.

[0025] Furthermore, the cleaning component 8 includes: a fixed plate 81, a rotating column 82, an annular groove 83, a gear 84, a rack 85, a sliding groove 86, a connecting rod 87, a guide column 88, a scraper 89, a sliding groove 810, a baffle 811, a cylindrical pin 812, a connecting rod 813, a cylindrical pin 814, and a waste bin 815. The fixed plate 81 is fixedly installed on the side wall of the filter box 2. By setting the fixed plate 81, the rotating column 82 can rotate inside it. The internal rotation of the fixed plate 81 is rotatably installed. A rotating column 82 has an annular groove 83 on its outer wall, which allows a guide column 88 to slide within it. A gear 84 is fixedly installed on the outer wall of the rotating column 82, meshing with a rack 85, which is fixedly installed on the side wall of the limiting plate 75.

The waste bin 815 is slidably installed inside the filter box 2.

[0026] Working principle: When the grain needs to be filtered, the filter device 3 is opened. At this time, the motor 37 rotates, which drives the rotating shaft 32 to rotate. The rotating shaft 32 drives the pulley 74 to rotate, which drives the pulley 73 to rotate. The rotating shaft 71 drives the rotating cam 72 to rotate. When the cam 72 rotates, it presses the stop rod 78. When the cam 72 presses the stop rod 78, it causes the stop rod 78 to move outward. When the stop rod 78 moves outward, it causes the limiting plate 75 to move outward. At the same time, when the cam 72 presses the stop rod 78, the spring 77 is stretched.

[0027] When the cam 72 moves away from the stop lever 78, the second spring 77 returns to its original position. When the second spring 77 returns to its original position, it drives the stop lever 78 to move inward. When the stop lever 78 moves inward, it drives the limiting plate 75 to move inward. This allows the grain to be limited, thus preventing the grain from accumulating on the filter screen 35 and enabling the filter device 3 to filter better, thereby improving working efficiency.

[0028] When the limiting plate 75 moves outward, it drives the rack 85 to move outward. When the rack 85 moves outward, it drives the gear 84 to rotate. When the gear 84 rotates, it drives the rotating column 82 to rotate. When the rotating column 82 rotates, it drives the guide column 88 to move downward in the annular groove 83. When the guide column 88 moves downward, it drives the connecting rod 87 to move downward in the first slide groove 86. When the connecting rod 87 moves downward, it drives the scraper 89 to move downward. When the scraper 89 moves downward, it drives the connecting rod 813 to move downward. When the connecting rod 813 moves downward, it drives the baffle 811 to move outward in the second slide groove 810. In this way, the broken leaves and dust adhering to the inner wall of the ash outlet 5 can be cleaned and enter the waste bin 815, thereby avoiding recontamination of the filtered grain.

[0029] When the limiting plate 75 moves inward, it drives the rack 85 to move inward. When the rack 85 moves inward, it drives the gear 84 to rotate. When the gear 84 rotates, it drives the rotating column 82 to rotate. When the rotating column 82 rotates, it drives the guide column 88 to move upward in the annular groove 83. When the guide column 88 moves upward, it drives the connecting rod 87 to move upward in the first slide groove 86. When the connecting rod 87 moves upward, it drives the scraper 89 to move upward. When the scraper 89 moves upward, it drives the connecting rod 813 to move upward. When the connecting rod 813 moves upward, it drives the baffle 811 to move inward in the second slide groove 810. In this way, the cleaning component 8 can be reset.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
