Description

Technical Field

[0001] The utility model belongs to the technical field of rice milling machine design, in particular to a feeding structure of a rice milling machine. Background Art

[0002] The vertical iron roller rice milling machine works by grinding grain into white rice through the rotation and friction of the iron rollers. It primarily consists of an emery roller, rice screen, rice cutter, discharge device, and transmission mechanism. The milling pressure is primarily controlled by a weight that lifts a tray via a lever, adjusting the size of the milling chamber outlet. After the brown rice flows into the milling chamber from the inlet, it is milled by the emery roller and rice screen. The rice bran outlet is connected to an external air source, where it enters the air duct.

[0003] At present, a Chinese patent with publication number CN217093619U and publication date of August 2, 2022 discloses a high-efficiency vertical rice milling machine, including a base and a rice milling machine body. The upper surface of the base is fixedly connected to a motor, and the inside of the rice milling machine body is vertically fixedly connected to a grinding cylinder, and the top of the grinding cylinder is fixedly connected to a top mesh plate. The lower surface of the top mesh plate is rotatably connected to a grinding roller, and the surface of the grinding roller is fixedly connected to spiral blades. The lower end of the left side wall of the rice milling machine body is penetrated and fixedly connected to a rice inlet, and the upper end of the right side wall of the rice milling machine body is penetrated and fixedly connected to a rice outlet.

[0004] The rice inlet of this high-efficiency vertical rice mill is set lower than the rice outlet. The spiral blades allow the rice to rise and finally be discharged through the rice outlet, which prolongs the rice milling time, makes the rice grains more fully milled, improves the milling efficiency, effectively avoids secondary milling, reduces the possibility of rice grains being crushed during over-milling, and ensures the appearance and quality of the rice.

[0005] When rice grains are put into the rice inlet, due to friction between the rice grains, the rice grains are likely to be blocked in the narrow rice inlet, resulting in poor rice feeding. Utility Model Content

[0006] The purpose of the utility model is to provide a feeding structure of a rice milling machine, which can help rice grains to smoothly enter the body of the rice milling machine.

[0007] The above technical objectives of the present utility model are achieved through the following technical solutions: a feeding structure of a rice milling machine, comprising a rice inlet provided on the side wall of the rice milling machine body, and a support plate connected to the side wall of the rice milling machine body near the rice inlet, a driving motor is provided on the support plate, a driving wheel is provided on the output shaft of the driving motor, a sleeve is fixed on the rice inlet, a spiral auger is rotatably connected in the sleeve, a connecting shaft is provided at the end of the spiral auger away from the rice inlet, a driven wheel is provided on the connecting shaft, a belt is provided between the driven wheel and the driving wheel, a base is provided on the upper side of the sleeve, and a feeding hopper is provided on the base.

[0008] The utility model is further configured as follows: a fixed cover is provided on one side of the upper end of the feed hopper, a transparent observation plate is provided in the middle of the fixed cover, and a movable cover is provided on the side of the upper end of the feed hopper away from the fixed cover.

[0009] The present invention is further configured as follows: the feed hopper is provided with a material guiding slope on the lower side of the movable cover plate, and a material guiding plate extending toward one side of the material guiding slope is provided in the feed hopper.

[0010] The present invention is further configured as follows: a plurality of magnet strips are arranged in the material guiding inclined surface.

[0011] The cam is secured to the bottom of the second support bracket, with the cam being secured to the bottom of the second support bracket and having a spring positioned at the top end of the cam.

[0012] The present invention is further configured as follows: a handle column is provided on the upper side of the fixing plate.

[0013] The present invention is further configured as follows: the support plate is provided with a protective mesh cover for wrapping around the outside of the driven wheel and the driving wheel.

[0014] In summary, the present invention has the following beneficial effects:

[0015] 1. Start the drive motor, which drives the driven wheel to rotate through the driving wheel and belt. The driven wheel can then drive the spiral auger in the sleeve to rotate. The operator puts the rice grains into the feed hopper. After the rice grains fall into the spiral auger, the rice grains can be driven by the spiral auger and move toward the rice mill body, which is conducive to the smooth entry of the rice grains into the rice mill body.

[0016] 2. The transparent observation plate on the fixed cover can be used to observe the rice grain conveying situation in the spiral auger. At the same time, the movable cover can be opened to conveniently put the rice grains into the feed hopper. The movable cover can be closed to prevent foreign debris from entering the feed hopper.

[0017] 3. The feed hopper uses the guide slope and guide plate to guide the rice grains, which helps the rice grains slide smoothly into the spiral auger below;

[0018] 4. When the rice grains slide down the guide slope, the multiple magnets installed in the guide slope can attract the iron filings and impurities in the rice grains, thereby preventing the iron filings and impurities from entering the rice mill body;

[0019] 5. When the feed hopper needs to be disassembled, pull up the positioning column and the connecting spring is stretched, then the positioning column can leave the first through hole, the second through hole and the third through hole, then rotate the rotating arm to move the rotating arm away from the first connecting plate, and then the feed hopper can be quickly removed from the base;

[0020] When the feed hopper needs to be installed, it is only necessary to fit the first connecting plate of the feed hopper onto the second connecting plate, and align the second through hole with the position of the third through hole, then rotate the rotating arm so that the rotating arm presses the first connecting plate onto the second connecting plate, and aligns the position of the first through hole with the position of the second through hole, then place the fixing plate, and after the elastic recovery of the connecting spring, the positioning column can be driven to pass through the first through hole, the second through hole and the third through hole in sequence, and finally the feed hopper can be quickly installed on the base.

[0021] 6. Use the handle column set on the upper side of the fixed plate to easily pull up the positioning column;

[0022] 7. The driven wheel and the driving wheel can be protected by a protective net to prevent the operator from accidentally touching them. BRIEF DESCRIPTION OF THE DRAWINGS
