[0002] The fruit of rice after husking is called caryopsis. From the perspective of rice production technology, it is composed of three parts: cortex, endosperm and embryo. From the physiological structure, it can be subdivided into several parts such as pericarp, seed coat, nucellus, aleurone, embryo, and endosperm. Germ rice is a kind of rice that retains the germ part of rice, while the other parts are exactly the same as white rice. In fact, the most important central part of rice is the germ, which has extremely high nutritional value. When the existing germ rice is processed using traditional grinding and polishing equipment, the rice grains move irregularly in it, and the germ part is easily damaged, which ultimately affects the product quality.

[0006] The two ends of the plurality of partition plates are slidably connected with a limiting frame, the limiting frame is slidably connected with a sliding frame outside, the plurality of partition plates are fixedly connected to the sliding frame, one side of the sliding frame is fixedly connected with a discharge box, and the other side of the sliding frame is fixedly connected with a feed box.

[0007] The processing method used by the germ rice processing equipment comprises the following steps:

DETAILED DESCRIPTION

[0026] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] like Figure 2 and Figure 3 , to ensure the stability of rice grains during processing.

[0029] Multiple partition plates 101 are slidably connected to the limiting frame 11, the limiting frame 11 is slidably connected in the sliding frame 105, the partition plates 101 are welded inside the sliding frame 105, the discharge box 107 is welded on one side of the sliding frame 105, and the feed box 108 is welded on the other side of the sliding frame 105.

[0030] During processing, the rice grains are first put into the equipment from the feed box 108, and the sliding frame 105 is driven to vibrate back and forth, so that the rice grains are evenly distributed in the limiting frame 11. Initially, the limiting frame 11 is located at the top, and during the vibration of the sliding frame 105, the rice grains located at the bottom fall into the gap between the partition plates 101, and then the limiting frame 11 moves downward, and at the same time the second lifting frame 203 drives the friction belt 204 to move downward, driving the friction belt 204 to work, and pushing the excess rice grains to the feed box 108, and then grinding the rice grains between the partition plates 101. After grinding, the limiting frame 11 is driven to continue to move downward, and at the same time the fixed rod 103 is driven to drive multiple grinding wheels 104 to move upward to between the arc plates 102, and then the rice grains between the partition plates 101 are lifted upward, and then the friction belt 204 is driven to rotate in the opposite direction, and then the ground rice grains are pushed from the other side to the discharge box 107 for collection.

[0031] like Figure 2 and Figure 3 , to ensure the stability of rice grains during processing.

[0032] Multiple partition plates 101 are slidably connected to the limiting frame 11, the limiting frame 11 is slidably connected in the sliding frame 105, the partition plates 101 are welded inside the sliding frame 105, the discharge box 107 is welded on one side of the sliding frame 105, and the feed box 108 is welded on the other side of the sliding frame 105.

[0033] During processing, the rice grains are first put into the equipment from the feed box 108, and the sliding frame 105 is driven to vibrate back and forth, so that the rice grains are evenly distributed in the limiting frame 11. Initially, the limiting frame 11 is located at the top, and during the vibration of the sliding frame 105, the rice grains located at the bottom fall into the gap between the partition plates 101, and then the limiting frame 11 moves downward, and at the same time the second lifting frame 203 drives the friction belt 204 to move downward, driving the friction belt 204 to work, and pushing the excess rice grains to the feed box 108, and then grinding the rice grains between the partition plates 101. After grinding, the limiting frame 11 is driven to continue to move downward, and at the same time the fixed rod 103 is driven to drive multiple grinding wheels 104 to move upward to between the arc plates 102, and then the rice grains between the partition plates 101 are lifted upward, and then the friction belt 204 is driven to rotate in the opposite direction, and then the ground rice grains are pushed from the other side to the discharge box 107 for collection.

[0034] like Figure 3 , in order to solve the problem of synchronous movement of the limiting frame 11 and the fixing rod 103.

[0035] The four first connecting rods 106 are cross-rotatably connected to the sliding frame 105 in groups of two, and each of the first connecting rods 106 is provided with a sliding groove at both ends. The sliding groove located at the top of each first connecting rod 106 is slidably connected to the limiting frame 11 on the same side, and the sliding groove located at the bottom of each first connecting rod 106 is slidably connected to the fixed rod 103 on the same side.

[0036] When the limiting frame 11 is moved downward, the upper end of the first connecting rod 106 is driven to rotate outward at the same time, thereby causing the lower ends of the two first connecting rods 106 to rotate outward at the same time, thereby driving the lower fixed rod 103 to move upward, thereby achieving the purpose of the fixed rod 103 moving upward synchronously when the limiting frame 11 moves.

[0037] like Figure 4 and Figure 5 , in order to solve the problem of movement of the first lifting frame 202 and the second lifting frame 203.

[0038] A sliding frame 12 is welded to the sliding frame 105 , and two hydraulic rods 201 are welded to the sliding frame 12 . The moving end of one of the hydraulic rods 201 is fixedly connected to a first lifting frame 202 , and the first lifting frame 202 is fixedly connected to the limiting frame 11 . The moving end of the other hydraulic rod 201 is fixedly connected to a second lifting frame 203 .

[0039] The hydraulic rod 201 is driven to extend and retract, thereby driving the limiting frame 11 to move up and down, and then driving the limiting frame 11 to move up when adding rice grains into the device, so that there are enough rice grains inside the device, and then when the device vibrates, it can be ensured that there are enough rice grains between the partition plates 101. During processing, the limiting frame 11 is moved downward, thereby ensuring that excess rice grains in the device can be discharged. Another hydraulic rod 201 is extended and retracted to drive the second lifting frame 203 to move up and down, and then drive the friction belt 204 to move up and down, so that it is simultaneously lowered when the excess rice grains are discharged to ensure the discharge effect.

[0040] like Figure 6 , in order to solve the problem of reprocessing the excess rice grains.

[0041] The housing 13 is fixed to the sliding frame 12 by screws, the conveyor belt 301 is arranged in the housing 13, a plurality of rotating plates 304 are rotatably connected to the conveyor belt 301, and the feed inclined plate 302 and the discharge inclined plate 303 are respectively welded in the discharge box 18.

[0042] The feeding inclined plate 302 is inclined with higher outer side and lower inner side. When placing rice grains into the equipment, they slide down along the feeding inclined plate 302. At this time, the edge of the limiting frame 11 contacts the lower end of the feeding inclined plate 302, so that the rice grains can be put into the limiting frame 11. When the excess rice grains are discharged outward, the limiting frame 11 moves down, and the discharging inclined plate 303 is set with higher inner side and lower outer side. The limiting frame 11 moves down to be level with the inner side of the discharging inclined plate 303, so that the excess rice grains can slide out along the discharging inclined plate 303, and then slide onto the rotating plate 304, thereby driving the conveyor belt 301 to rotate, driving the rotating plate 304 to move upward to the feeding inclined plate 302, and at the same time rotating the rotating plate 304 so that the rice grains on it slide onto the feeding inclined plate 302 for re-grinding.

[0043] like Figure 6 and Figure 7 , in order to solve the problem that the rotating plate 304 moves to the feeding inclined plate 302 and rotates at the same time to make the rice grains slide onto the feeding inclined plate 302.

[0044] Two protrusions 305 are welded to the outer side of each rotating plate 304 , and two arc-shaped stoppers 306 are welded to the outer side of the discharge box 108 .

[0045] As the conveyor belt 301 rotates, the rotating plate 304 is driven to move upward. At this time, the outer side of the rotating plate 304 is higher than the inner side, so that the rice grains are confined between the conveyor belt 301 and the rotating plate 304. When the protrusion 305 on the rotating plate 304 contacts the arc-shaped stopper 306, as the conveyor belt 301 continues to move, the arc-shaped stopper 306 blocks the protrusion 305, so that the rotating plate 304 rotates and becomes a state with the outer side low and the inner side high, so that the rice grains thereon can slide along the feed inclined plate 302. As the rotating plate 304 continues to rotate, the arc-shaped stopper 306 no longer contacts the protrusion 305, so as to avoid getting stuck in the conveyor belt 301.

[0046] like Figure 7 and Figure 8 , in order to solve the resetting problem of the rotating plate 304.

[0047] Two return coil springs 307 are welded at the rotation connection between each rotating plate 304 and the conveyor belt 301 , and each limit block 308 is welded on the inner side of the rotating plate 304 .

[0048] The reset coil spring 307 pulls the rotating plate 304 so that it is always in a state where the inner side is low and the outer side is high. When the rotating plate 304 rotates to make the rice grains fall onto the inlet inclined plate 302, the reset coil spring 307 pulls the rotating plate 304 to reset. At the same time, the limit block 308 ensures that the angle of the rotating plate 304 after reset is the same as that of the discharge inclined plate 303 to prevent the rice grains from falling.

[0049] like Fig. 9 and Fig.10 , in order to solve the problem of vibration of the sliding frame 105.

[0050] The equipment support 14 is slidably connected to the lower side of the sliding frame 13 , and a push rod 403 is fixedly connected to the sliding frame 105 , and the push rod 403 and the equipment support 14 are slidably connected.

[0051] The equipment bracket 14 supports the entire equipment. When rice grains are added to the equipment, in order to ensure that the rice grains are evenly distributed in the limiting frame 11, the push rod 403 is driven to move back and forth, thereby driving the sliding frame 105 to move back and forth, and then driving the limiting frame 11, the sliding frame 12 and the partition plate 101 and other fixed parts to move back and forth synchronously, achieving a vibration effect and evenly spreading the internal rice grains.

[0052] like Fig. 9 and Fig.10 , in order to solve the problem of push rod 403 moving.

[0053] A turntable 401 is rotatably connected to the equipment bracket 14 , one end of a second connecting rod 402 is rotatably connected to an eccentric position of the turntable 401 , and the other end of the second connecting rod 402 is rotatably connected to a push rod 403 .

[0054] The turntable 401 is driven to rotate, thereby causing the second connecting rod 402 at its eccentric position to move, thereby driving the other end of the second connecting rod 402 to move, and then driving the push rod 403 to move. The push rod 403, the second connecting rod 402 and the turntable 401 together form a crank-connecting rod mechanism, thereby achieving the purpose of driving the push rod 403 to move back and forth.

[0055] like Fig.11 , a processing method used in a germ rice processing device, the method comprising the following steps;

[0056] S1: Place the rice to be polished on the inlet inclined plate 302 and let it slide into the equipment;

[0057] S2: driving the rotating disk 401 to rotate, so that the rice is evenly distributed in the limiting frame 11 by vibration, and then simultaneously moving the first lifting frame 202 and the second lifting frame 203 downward;

[0058] S3: driving the friction belt 204 to rotate and discharge the excess rice grains, and then driving the grinding wheel 104 to rotate and grind the rice between the partition plates 101;

[0059] S4: Move the first lifting frame 202 and the second lifting frame 203 downward, and drive the friction belt 204 to rotate in the opposite direction to collect the polished rice;

[0060] S5: driving the first lifting frame 202 and the second lifting frame 203 to reset, and then driving the conveyor belt 301 to rotate, so as to transport the excess rice discharged in the previous step back for further processing;

[0061] S6: Repeat S1 to S5.
