[0022] The rotating mechanism 30 comprises a fixed cylinder 31, a rotating shaft 32, a rotating arm 33 and a motor 34. The fixed cylinder 31 is arranged transversely in the interior of the grinding cylinder 20 and fixedly connected with the grinding cylinder 20. The rotating shaft 32 is arranged in the interior of the fixed cylinder 31 and rotatably connected with the fixed cylinder 31 through a bearing. The axis of the rotating shaft 32, the axis of the fixed cylinder 31 and the axis of the grinding cylinder 20 are arranged in a straight line. The rotating arm 33 is arranged outside the inlet 22 and fixedly connected with the rotating shaft 32. The motor 34 is fixedly installed on the grinding cylinder 20 and electrically connected with the control cabinet, and the motor 34 is used to control the rotation of the rotating shaft 32.
[0023] The grinding mechanism 40 comprises a horizontal plate 41, a grinding roller 42 and a guide assembly 43. The horizontal plate 41 is arranged in the interior of the grinding cylinder 20 and fixedly connected with the rotating arm 33. The grinding roller 42 is arranged in the interior of the grinding cylinder 20 and located outside the horizontal plate 41. The guide assembly 43 comprises a guide rod 431 and a tension spring 432. The guide rod 431 passes through the horizontal plate 41 and is slidably connected with the horizontal plate 41, and the guide rod 431 is connected with the grinding roller 42. The tension spring 432 is sleeved on the guide rod 431, the first end of the tension spring 432 is fixedly connected with the horizontal plate 41, and the second end of the tension spring 432 is fixedly connected with the grinding roller 42, so that the grinding roller 42 has a tendency to approach the horizontal plate 41.
[0024] The pushing mechanism 50 is used to control the step-by-step outward movement of the guide rod 431.
[0025] The specific working process of the device is as follows: Firstly, the staff adds rice into the grinding cylinder 20 through the inlet 22, and under the action of gravity, the rice will be accumulated at the bottom of the grinding cylinder 20.
[0026] Then, the staff controls the motor 34 to start through the control cabinet, and when the motor 34 starts, it can drive the rotating shaft 32 and the rotating arm 33 to rotate, and under the transmission of the horizontal plate 41 and the guide rod 431, the grinding roller 42 will also rotate in the grinding cylinder 20, thereby performing grinding work on the rice in the grinding cylinder 20.
[0027] Then, the pushing mechanism 50 controls the guide rod 431 to move outward step by step, the distance between the grinding roller 42 and the inner wall of the grinding cylinder 20 is gradually reduced, so that the force between the grinding roller 42 and the rice is gradually increased.
[0028] Therefore, the grinding degree of the device on the rice is gradually increased, and the grinding effect is better and the grinding process is smooth.
[0029] After the grinding operation is completed, the staff places the collection box below the discharge port 23, and then opens the discharge valve, so that the ground rice is automatically discharged.
[0030] In one embodiment, the pushing mechanism 50 includes a guide cylinder 51 and a telescopic assembly 52.
[0031] The guide cylinder 51 is sleeved on the fixed cylinder 31, and a plurality of annular guide grooves are formed on the outer circumferential surface of the guide cylinder 51. The plurality of annular guide grooves are arranged at equal intervals along the axial direction of the guide cylinder 51. The groove depth of the plurality of annular guide grooves gradually decreases from inside to outside, that is, the groove depth of the annular guide groove closer to the outside is smaller. Adjacent two annular guide grooves are connected by a gap, and the annular guide groove is matched with the guide rod 431.
[0032] The telescopic assembly 52 is used to control the movement of the guide cylinder 51 on the fixed cylinder 31.
[0033] For the convenience of explaining the working principle, the plurality of annular guide grooves on the guide cylinder 51 are sequentially named as the first annular guide groove 511, the second annular guide groove 512, the third annular guide groove 513, and so on from inside to outside. In the initial state, the head of the guide rod 431 abuts against the bottom of the first annular guide groove 511 due to the action of the tension spring 432.
[0034] First grinding operation: the motor 34 drives the rotating shaft 32, the rotating arm 33 and the horizontal plate 41 to rotate, the head of the guide rod 431 slides in the first annular guide groove 511, and the grinding roller 42 also rotates in the grinding cylinder 20, thereby performing the first grinding operation on the rice in the grinding cylinder 20. After the first grinding operation is completed, the motor 34 is turned off, and the head of the guide rod 431 is aligned with the gap.
[0035] Second grinding operation: the telescopic assembly 52 drives the guide cylinder 51 to move inward, the head of the guide rod 431 will pass through the gap into the second annular guide groove 512, and the head of the guide rod 431 will abut against the bottom of the second annular guide groove 512 under the action of the tension spring 432. The motor 34 is started to drive the rotating shaft 32, the rotating arm 33 and the horizontal plate 41 to rotate, the head of the guide rod 431 slides in the second annular guide groove 512, and the grinding roller 42 will rotate in the grinding cylinder 20, so as to perform the second grinding operation on the rice in the grinding cylinder 20. After the second grinding operation is completed, the motor 34 is turned off, and the head of the guide rod 431 is aligned with the gap. Since the groove depth of the second annular guide groove 512 is smaller, the distance between the grinding roller 42 and the inner wall of the grinding cylinder 20 is smaller, so that the force between the grinding roller 42 and the rice is increased.
[0036] Third grinding operation: the telescopic assembly 52 drives the guide cylinder 51 to continue to move inward, the head of the guide rod 431 will pass through the gap into the third annular guide groove 513, and the head of the guide rod 431 will abut against the bottom of the third annular guide groove 513 under the action of the tension spring 432. The motor 34 is started to drive the rotating shaft 32, the rotating arm 33 and the horizontal plate 41 to rotate, the head of the guide rod 431 slides in the third annular guide groove 513, and the grinding roller 42 will rotate in the grinding cylinder 20, so as to perform the third grinding operation on the rice in the grinding cylinder 20. After the second grinding operation is completed, the motor 34 is turned off, and the head of the guide rod 431 is aligned with the gap. Since the groove depth of the third annular guide groove 513 is smaller, the distance between the grinding roller 42 and the inner wall of the grinding cylinder 20 is smaller, so that the force between the grinding roller 42 and the rice is increased.
[0037] Subsequent grinding operations continue according to the above rules, so that the grinding force of the device on the rice is gradually increased, and the grinding effect is better and the grinding process is smooth.
[0038] When the rice grinding is completed, the device resets, and the reset process is opposite to the above process, which will not be described again.
[0039] In an embodiment, the telescopic assembly 52 includes a guide rail 521 and an electric push rod 522. The guide rail 521 is fixedly installed on the outer circumferential surface of the fixed cylinder 31 in the transverse direction, and is in sliding connection with the guide cylinder 51. The electric push rod 522 is arranged in the transverse direction and is electrically connected with the control cabinet, the housing of the electric push rod 522 is fixedly installed on the fixed cylinder 31, and the piston rod of the electric push rod 522 is fixedly connected with the guide cylinder 51.
[0040] In the initial state, the piston rod of the electric push rod 522 is in the elongated state.
[0041] When the telescopic assembly 52 is in operation, the control cabinet controls the piston rod of the electric push rod 522 to retract, and the guide cylinder 51 moves inward on the guide rail 521, so that the head of the guide rod 431 passes through the gap and enters the next annular guide groove.
[0042] The telescopic assembly 52 has a simple structure and is convenient to operate.
[0043] In an embodiment, the guide assembly 43 further comprises a guide ring 433. The guide ring 433 is sleeved on the grinding roller 42 and rotationally connected with the grinding roller 42, and the guide ring 433 is fixedly connected with the guide rod 431. The guide ring 433 is fixedly connected with the second end of the tension spring 432.
[0044] This design allows the grinding roller 42 to freely roll during the grinding operation, so that the grinding operation is more smooth.
[0045] In an embodiment, the number of guide assemblies 43 is two, and the two guide assemblies 43 are respectively located at the two ends of the horizontal plate 41.
[0046] Correspondingly, the number of pushing mechanisms 50 is two, and the two pushing assemblies are respectively arranged corresponding to the two guide assemblies 43.
[0047] The two guide assemblies 43 and the two pushing mechanisms 50 respectively act on the two ends of the grinding roller 42, so that the grinding roller 42 is more stable during the operation and the stress distribution is more uniform.
[0048] In an embodiment, a disturbance plate 35 is further included, and the disturbance plate 35 is fixedly installed on the rotating arm 33.
[0049] During the rotation of the rotating shaft 32 and the rotating arm 33, the disturbance plate 35 also rotates synchronously. After the grinding roller 42 grinds the rice once, the disturbance plate 35 disturbs the ground rice once, and the two operations are alternately performed.
[0050] During the disturbance of the disturbance plate 35, the rice is turned up multiple times, so that the rice at the bottom is turned up to the surface and contacts the grinding roller 42, further improving the grinding effect of the device.
[0051] In an embodiment, the disturbance plate 35 and the grinding cylinder 20 are respectively located at the two ends of the rotating arm 33.
[0052] In an embodiment, an annular limiting groove 21 is formed on the front end surface of the grinding cylinder 20, and a limiting block 36 is fixedly installed at each end of the rotating arm 33, and the limiting block 36 is in sliding contact with the inner wall of the annular guide groove.
[0053] The cooperation of the annular limiting groove 21 and the limiting block 36 can guide and balance the force of the two ends of the rotating arm 33, so that the rotating process of the rotating arm 33 is more stable.
