Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a flow control mechanism for rice feeding. Background Art

[0002] Rice is made from paddy rice through three processes: cleaning, husking and milling. It contains nearly 64% of the nutrients in rice and more than 90% of the nutrients needed by the human body. The rice sold on the market is all processed.

[0003] The existing rice processing cannot control and adjust the rice feed flow rate, resulting in high difficulty in operation during actual use, and the size of the feed port cannot be accurately determined, thereby affecting the adjustment accuracy. In addition, the existing rice processing cannot automatically feed the rice, and the feeding is all done manually, resulting in a large amount of labor, thereby increasing the labor cost. Based on these problems, Chinese patent CN217568851U discloses a rice feed flow adjustment mechanism for rice processing, which drives a motor to rotate a rotating rod through a flow control mechanism, and drives the rotating rod to rotate a first disc, and an annular slide groove on the first disc is slidably connected with an annular slider, so that a first through hole on the first disc and a second through hole on the second disc are aligned, thereby causing the rice to fall, and by controlling the alignment angle of the first through hole and the second through hole, the flow rate of the rice discharge is indirectly controlled, which is simple and convenient to use and improves the adjustment accuracy.

[0004] The feed pipe in the feed mechanism is provided with a plurality of groups of openings, and the openings have a certain length. When the conical barrel moves downward, the bottom ends of the openings will expose the placement grooves. At this time, the rice in the placement grooves will continue to flow into the feed pipe, so that part of the rice will leak from the bottom end of the openings. If the discharge speed of the rice in the conical barrel is too slow, more rice will leak from the openings, thereby causing waste of rice. Utility Model Content

When the storage tank moves upward and the top cover touches the second contact switch, the second discharge valve will open, and the control module will also close the first discharge valve. When the storage tank moves downward and the first contact switch touches the bottom of the inner wall of the protective shell, the first discharge valve will open, and the control module will also close the second discharge valve.

[0023] (3) By providing a replenishing tank, the rice that needs to be replenished can be stored. By providing a connection structure between the plug shaft, the sleeve and the nut, the replenishing tank can be fixed on the top of the storage tank. By providing a simple connection method between the plug shaft, the sleeve and the nut, the disassembly and assembly steps of the replenishing tank are made more convenient and quick, and it is also convenient to clean the inside of the replenishing tank. After the replenishing tank is removed, the staff can also clean the inside of the storage tank. BRIEF DESCRIPTION OF THE DRAWINGS
