Description

Technical Field

[0001] This invention belongs to the technical field of grain processing equipment, specifically relating to a rice huller with automatic dust removal function. Background Technology

[0002] The purpose of rice processing is to separate the endosperm from other parts with minimal breakage, thereby producing rice with better eating quality. The process of removing the husk from rice to make brown rice is called rice hulling, and the machinery used for rice hulling is called a rice hulling machine. For example, a uniform feeding rice hulling machine with patent publication number CN221208183U uses multiple distributing rods and rollers to uniformly pulverize the rice, causing it to fall into a box. The relative rotation of the rubber rollers on both sides then removes the husk from the falling rice. An inclined screen removes dust and impurities from the rice and collects them in a collection box. The rice is then collected through an outlet with a collection hood. However, using only a screen to sieve the rice is inefficient, and the fixed distance between the rubber rollers on both sides cannot be adjusted according to the actual use, reducing the practicality of the equipment.

Detailed Implementation

[0066] Further, the transmission part 76 comprises a fixed block 761 fixedly arranged in the bottom of the box body 1, and a rotating groove 762 arranged at the top center of the fixed block 761; a pair of rotating rods 763 symmetrically and rotatably arranged on the fixed block 761, and the top ends of the rotating rods 763 are arranged in the rotating groove 762; a pair of protrusions 764 respectively connected with the top ends of the rotating rods 763; a rotating block 765 rotatably connected with the protrusions 764 through a fixed rod one 766 arranged at the bottom side of the rotating block 765; wherein the rotating block 765 is in transmission cooperation with the fixed disc 74.

[0067] The fixed block 761 is fixedly arranged on the bottom surface in the box body 1, and the top of the fixed block 761 is provided with the rotating groove 762; the fixed cylinder 767 is fixedly arranged on the top of the fixed block 761, and the fixed cylinder 767 is in communication with the rotating groove 762.

[0068] The rotating rods 763 are provided with two ends, and are symmetrically and rotatably arranged on the two ends of the fixed block 761, and the end of one end extends into the rotating groove 762, and the other end is rotatably arranged on the box body 1; the protrusions 764 are fixedly arranged on one end of the rotating rods 763 located in the rotating groove 762, and the rotation of the rotating rods 763 can drive the rotation of the protrusions 764.

[0069] The rotating block 765 is arranged between the protrusions 764 on the two sides, and the fixed rod one 766 is rotatably arranged on the bottom outer side of the rotating block 765, and the rotating block 765 is rotatably connected with the protrusions 764 on the two sides through the fixed rod one 766, and the rotation of the protrusions 764 can drive the movement of the rotating block 765.

[0070] The sliding block 768 is slidably arranged in the fixed cylinder 767, and the mounting groove 769 is arranged on the bottom of the sliding block 768; the fixed rod two 770 is rotatably arranged on the top sides of the rotating block 765, and the other end of the fixed rod two 770 is rotatably arranged on the inner wall of the mounting groove 769, so as to realize the reciprocating sliding of the sliding block 768 in the fixed cylinder 767 driven by the rotating block 765.

[0071] A fixed plate 74 is slidably installed inside the top of the fixed cylinder 767. The fixed plate 74 abuts against the sliding block 768, and the fixed plate 74 can be moved by the movement of the sliding block 768. A striking rod 71 is fixedly installed on the top surface of the fixed plate 74. The top of the striking rod 71 extends through the collecting plate 4 to the bottom of the screen 5. A striking plate 72 is fixedly installed on the top of the striking rod 71. The movement of the fixed plate 74 drives the striking plate 72 to move, and the movement of the striking plate 72 strikes the screen 5, thereby increasing the vibration frequency of the screen 5.

[0072] A rubber block is fixedly installed on the top surface of the striking plate 72. The rubber block reduces the noise generated by the impact between the striking plate 72 and the screen 5, and protects the screen 5.

[0073] A limiting cylinder is fixedly installed on the bottom surface of the collecting tray 4.

[0074] Spring 75 is sleeved on the outside of striking rod 71, and its two ends are fixedly connected to collecting plate 4 and fixed plate 74. By setting spring 75, the fixed plate 74, striking rod 71 and striking plate 72 can be reset.

[0075] The relevant drive mechanism is activated, which drives the rotating rod 763 to rotate. The rotating rod 763 drives the protrusion 764 to rotate. The rotation of the protrusion 764 causes the rotating block 765 and the sliding block 768 to slide up and down inside the fixed cylinder 767. When the sliding block 768 slides upward, it pushes the fixed disk 74, the striking rod 71, and the striking disk 72 to move upward and strike the screen 5, increasing the vibration frequency of the screen 5 and improving the screening efficiency of the screen 5. At the same time as the fixed disk 74 moves upward, it compresses the spring 75, causing the spring 75 to deform. When the sliding block 768 slides downward, the spring 75 recovers its deformation and pushes the fixed disk 74 back to its original position. The fixed disk 74, striking rod 71, and striking disk 72 are reset. Through the above process, the screen 5 is struck, thus accelerating the screening efficiency of the screen 5.
