[0039] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0040] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] Embodiment 1:

[0042] A germ rice processing device, such as Figure 1 - Figure 8 As shown, it includes a shell 1, and the middle inner wall of the shell 1 is provided with a grinding outer ring 2 and a grinding inner roller 3 that match each other, and a "V"-shaped grinding gap 7 is formed between the grinding outer ring 2 and the grinding inner roller 3. The top outer wall of the grinding inner roller 3 is fixedly connected to the main shaft 9 through an arch block 8, and the outer wall of the main shaft 9 is rotatably connected to a connecting frame 11, and a slide plate 31 is fixed to the outer circumferential wall of the connecting frame 11. The inner wall of the shell 1 is provided with a slide groove 30 that slidably matches the slide plate 31, and the top inner side of the shell 1 is provided with a joint drive component 10 for rotating the main shaft 9 and lifting and lowering the connecting frame 11.

[0043] A partition plate 12 is fixed to the inner wall of the shell 1 , and the main shaft 9 is movably inserted into the inner wall of the partition plate 12 . A feed hopper 6 is fixed to the outer wall of one side of the shell 1 , and the feed hopper 6 is connected to the inner cavity of the shell 1 located below the partition plate 12 .

[0044] A switchable discharge assembly 4 is provided at the bottom discharge port of the shell 1 , and the top and bottom of the grinding outer ring 2 are connected to the shell 1 through a pleated sealing ring 5 .

[0045] When the device is in use, germ rice can be put into the feed hopper 6, and the raw material enters the inner cavity of the shell 1 through the feed hopper 6, and then the grinding inner roller 3 is driven to rotate by the joint drive component 10, and the raw material enters the grinding gap 7 between the grinding outer ring 2 and the grinding inner roller 3, and is gradually ground downward by gravity. After grinding, it is discharged through the switching discharge component 4. When foreign matter is stuck, the joint drive component 10 will drive the connecting frame 11 to rise, thereby pulling the grinding inner roller 3 up through the main shaft 9, so that the grinding gap 7 is enlarged, and the foreign matter is discharged by gravity.

[0046] The device uses the grinding outer ring 2 and the grinding inner roller 3 to grind together. On the one hand, the "V"-shaped structure of the grinding gap 7 can realize step-by-step grinding, and the grinding can be discharged only when the gap is smaller than the minimum gap of the grinding gap 7, which can simplify the subsequent screening steps. On the other hand, when jamming occurs, the gap of the grinding gap 7 can be increased by moving the grinding inner roller 3 upward, so that foreign matter can be discharged, preventing the combined drive component 10 from being overloaded and damaged.

[0047] In order to solve the joint drive problem; such as Figure 3 - Figure 6 As shown, the combined drive assembly 10 includes a sun gear 14, an outer ring gear 17 and a plurality of planetary gears 15, the outer ring gear 17 is rotatably connected to the inner wall of the housing 1, a plurality of planetary gears 15 are meshed in a circular array on the inner side of the outer ring gear 17, and the planetary gears 15 are axially limited by the outer ring gear 17, the sun gear 14 is meshed on the inner side of the plurality of planetary gears 15, a drive motor 13 is fixed to the top outer wall of the housing 1 by bolts, the output shaft of the drive motor 13 is fixed to the inner wall of the sun gear 14, and the bottom of the plurality of planetary gears 15 is rotatably connected to the same planet carrier 18.

[0048] The outer wall of the housing 1 is provided with a damping member 16 for applying rotational damping to the outer gear ring 17, and the damping applied by the damping member 16 to the outer gear ring 17 is greater than the rotational damping of the raw material on the grinding inner roller 3 during grinding.

[0049] The main shaft 9 is loosely fitted in the inner wall of the planet carrier 18 via a key-shaped protrusion 19 provided on the outer wall of the main shaft 9 .

[0050] A spring 20 is buckled on the outer wall of the main shaft 9 , and the other end of the spring 20 is buckled on the bottom of the planet carrier 18 .

[0051] The outer wall of the connecting frame 11 is provided with an annular corrugated groove 21 , and a limiting column 22 is fixed to the bottom of the outer gear ring 17 . The limiting column 22 contacts and moves in a limiting manner with the inner wall of the outer gear ring 17 .

[0052] When the drive motor 13 is started, it can drive the sun gear 14 to rotate. At this time, since the damping applied by the damping member 16 to the outer ring gear 17 is greater than the rotational damping of the raw material on the grinding inner roller 3 during grinding, the outer ring gear 17 is in a fixed state, and the sun gear 14 drives the planetary gear 15 to rotate, thereby driving the main shaft 9 to rotate through the planetary carrier 18, and then grinding is performed through the rotation of the grinding inner roller 3. When foreign matter is stuck, the rotational damping of the grinding inner roller 3 increases and stops rotating, thereby increasing the rotational damping of the planetary gear 15 and stopping the revolution. At this time, the power of the drive motor 13 is transmitted to the outer ring gear 17, and the outer ring gear 17 overcomes the damping of the damping member 16 and rotates, thereby driving the connecting frame 11 to reciprocate and rise and fall through the mutual limiting action of the annular corrugated groove 21 and the limiting column 22, thereby increasing the gap of the grinding gap 7, so that foreign matter is gradually discharged from the grinding gap 7 by gravity, and the stuck state is released.

[0053] The present device, by providing a combined drive assembly 10, can realize the rotation drive of the main shaft 9 for grinding operation drive on the one hand, and can also realize the longitudinal displacement drive of the grinding inner roller 3 in a stuck state through the cooperation of the annular corrugated groove 21 and the limit column 22 for driving out of trouble, thereby realizing the power integration of the two and simplifying the power arrangement.

[0054] In addition, the device sets the combined drive assembly 10 as a combination of a sun gear 14, a planetary gear 15, and an outer ring gear 17, utilizes the two degrees of freedom of its transmission to be interconnected, and combines the damping of the outer ring gear 17 by the damping element 16, so that during normal operation, all power is input to grinding, and when stuck, the power is automatically switched to escape, without the need for manual or electronic control algorithm control, thereby simplifying the control logic.

[0055] The damping member 16 includes a gantry 25 and a friction plate 26. The gantry 25 is fixed to the outer wall of the housing 1 by bolts. The friction plate 26 is slidably connected to the gantry 25 through a guide rod 1 23, and the friction plate 26 contacts and frictionally fits the outer wall of the outer gear ring 17. The outer wall of the friction plate 26 is buckled with a spring 24, and the other end of the spring 24 is buckled to the inner wall of the gantry 25.

[0056] The friction plate 26 is acted upon by the elastic force of the spring 24 , so that there is contact pressure between the friction plate 26 and the outer gear ring 17 , thereby performing friction damping.

[0057] In order to solve the problem of fineness adjustment; Figure 7 As shown, the grinding outer ring 2 is axially slidably connected to the interior of the shell 1 through a guide rod 29, and the inner wall of the shell 1 is threadedly connected to a screw rod 27, the end of the screw rod 27 is rotationally connected to the grinding outer ring 2, and the outer wall of the screw rod 27 is threadedly connected to a locking nut 28.

[0058] The device, by providing components such as a screw rod 27, a locking nut 28, and a guide rod 29, can utilize the rotation of the screw rod 27 to change the position of the grinding outer ring 2 relative to the grinding inner roller 3, thereby changing the size of the grinding gap 7 and achieving control of the grinding fineness. In addition, by providing the locking nut 28, it can increase the static friction force of the threaded pair between the screw rod 27 and the housing 1 in a fixed state, thereby playing a role in preventing loosening.

[0059] In order to solve the problem of discharging materials; Figure 8 As shown, the switching discharge assembly 4 includes a "Y"-shaped discharge channel 32 fixed to the bottom of the shell 1, the middle part of the "Y"-shaped discharge channel 32 is rotatably connected to a revolving door 34, the outer wall of the "Y"-shaped discharge channel 32 is fixed with a switching motor 33 by bolts, and the output shaft of the switching motor 33 is fixed to the side wall at the rotation center of the revolving door 34.

[0060] When in the normal grinding state, the switching motor 33 controls the rotating door 34 to rotate, blocking one of the "Y"-shaped discharge channels 32, and the other channel is used as the finished product discharge channel. When foreign matter is stuck, the switching motor 33 drives the rotating door 34 to switch to the state of blocking the finished product discharge channel, and the foreign matter can be discharged from the open channel.

[0061] The device is provided with a "Y"-shaped discharge channel 32, utilizes the double-channel characteristics of the "Y"-shaped discharge channel 32, and combines the rotation blockage of the rotary door 34, so that during normal grinding and discharge of foreign matter, foreign matter and finished products can be output through different channels respectively, thereby saving the subsequent step of screening foreign matter and improving efficiency.

[0062] When the present embodiment is in use, the germ rice can be put into the feed hopper 6, and the raw material enters the inner cavity of the shell 1 through the feed hopper 6. When the drive motor 13 is started, it can drive the sun gear 14 to rotate. At this time, since the damping applied by the damping member 16 to the outer gear ring 17 is greater than the rotation damping of the raw material on the grinding inner roller 3 during grinding, the outer gear ring 17 is in a fixed state, and the sun gear 14 drives the planetary gear 15 to rotate, thereby driving the main shaft 9 to rotate through the planetary carrier 18, and then grinding is performed through the rotation of the grinding inner roller 3. When foreign matter is stuck, the rotation damping of the grinding inner roller 3 increases and stops rotating, thereby increasing the rotation damping of the planetary gear 15 and stopping the revolution. At this time, the drive motor The power of 13 is transmitted to the outer gear ring 17, and the outer gear ring 17 overcomes the damping of the damping member 16 and rotates, thereby driving the connecting frame 11 to reciprocate and rise and fall through the mutual limiting action of the annular corrugated groove 21 and the limiting column 22, thereby increasing the gap of the grinding gap 7, so that foreign matter is gradually discharged from the grinding gap 7 by gravity, and the stuck state is released. When in the normal grinding state, the switching motor 33 controls the rotating door 34 to rotate, blocking one of the channels of the "Y"-shaped discharge channel 32, and the other channel is used as the finished product discharge channel. When foreign matter is stuck, the switching motor 33 drives the rotating door 34 to switch to the state of blocking the finished product discharge channel, and the foreign matter can be discharged from the open channel.

[0063] Embodiment 2:

[0064] A processing method of germ rice processing equipment comprises the following steps:

[0065] S1: Put the germ rice into the feed hopper 6, the germ rice enters the inner cavity of the housing 1 through the feed hopper 6, and then start the driving motor 13 for grinding;

[0066] S2: When a foreign object is stuck, the connecting frame 11 is lifted and lowered reciprocatingly, thereby increasing the gap of the grinding gap 7, so that the foreign object is gradually discharged from the grinding gap 7 by gravity;

[0067] S3: When in the normal grinding state, the switching motor 33 controls the rotating door 34 to rotate, blocking one of the "Y"-shaped discharge channels 32, and the other channel is used as the finished product discharge channel.
