[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0030] See attached Figure 1 -Attached Figure 7 A rice moderate grinding device comprises a grinding seat 1 and a grinding cone 8. A conical grinding groove 2 is opened inside the grinding seat 1. The angle between the conical surface of the grinding cone 8 and the conical grinding groove 2 gradually decreases from top to bottom, so as to perform the operation of coarse grinding to fine grinding of rice; a door frame 3 is fixedly installed on the top of the grinding seat 1, and two electric telescopic rods 4 are fixedly installed on the top of the door frame 3. The telescopic ends of the two electric telescopic rods 4 pass through the top of the door frame 3 and are fixedly installed with a supporting ring 5. A turntable 6 is rotatably installed on the inner wall of the support ring 5. A connecting shaft 7 is fixedly installed on the bottom end of the turntable 6. The bottom end of the connecting shaft 7 passes through the top of the grinding seat 1 and is fixedly installed with the rotation center of the grinding cone 8. A driving mechanism for driving the grinding cone 8 to rotate is installed on the door frame 3.
[0031] In this embodiment, the driving mechanism includes a driving motor 28 fixedly mounted on the top of the portal frame 3. The output end of the driving motor 28 passes through the top of the portal frame 3 and is fixedly mounted with a driving shaft 9. The bottom end of the driving shaft 9 is fixedly mounted with a driving disk 10. An overload protection component is installed between the driving disk 10 and the turntable 6.
[0032] In this embodiment, the overload protection component includes a plurality of guide rods 12 which are uniformly inserted through the upper surface of the driving disk 10 in a circumferential direction, a connecting ring 11 is fixedly installed at the top of the plurality of guide rods 12, a trapezoidal block 13 is fixedly installed at the bottom end of each guide rod 12, a plurality of slots 14 matching the trapezoidal blocks 13 are uniformly opened in a circumferential direction on the upper surface of the turntable 6, an elastic shrinking ring is fixedly installed at the top of the portal frame 3, and the elastic shrinking ring has a certain shrinking stroke through the setting of the elastic shrinking ring to prevent the top of the turntable 6 from abutting against the bottom end of the trapezoidal block 13 when the grinding cone 8 is lifted upward as a whole, resulting in the grinding cone 8 being unable to be lifted upward, a touch switch 16 is fixedly installed at the bottom end of the elastic shrinking ring, and the touch switch 16 is arranged directly above the connecting ring 11, and a compression spring 15 is sleeved on the outer surface of the guide rod 12, and the compression spring 15 is arranged between the driving disk 10 and the trapezoidal block 13.
[0033] When in use, the output end of the driving motor 28 drives the driving shaft 9 to rotate, so that the driving shaft 9 drives the driving disk 10 to rotate, and the driving disk 10 drives the multiple guide rods 12 and the trapezoidal block 13 to rotate. Since the trapezoidal block 13 is inserted into the slot 14 in the initial state, under the elastic force of the compression spring 15, the resistance between the inclined surface of the trapezoidal block 13 and the slot 14 can drive the turntable 6 to rotate, so that the turntable 6 drives the grinding cone 8 to rotate through the connecting shaft 7, so that the gap between the grinding cone 8 and the conical grinding groove 2 can be used to grind the rice, and the ground rice enters the discharge hole 22 from the bottom of the grinding seat 1 and is discharged through the discharge pipe 27, so that the ground rice can be collected.
[0034] In this embodiment, a support frame 17 is fixedly installed on the outer surface of the portal frame 3, a feed hopper 18 is fixedly installed on the outer surface of the support frame 17, a feed pipe 19 connected with the interior of the feed hopper 18 is fixedly installed at the bottom end of the feed hopper 18, the feed pipe 19 is arranged through the top of the grinding seat 1, and the bottom end of the feed pipe 19 matches the top curved surface of the grinding cone 8.
[0035] When the grinding cone 8 is lifted upward, the bottom end of the feed pipe 19 will abut against the top of the grinding cone 8, so that the grinding cone 8 can block the bottom end of the feed pipe 19 to prevent the pre-filled rice in the feed hopper 18 from falling and being discharged.
[0036] In this embodiment, a discharge mechanism is installed at the bottom of the grinding seat 1, and the discharge mechanism includes two guide rails 20 fixedly installed at the bottom of the grinding seat 1, and a movable block 21 is slidably installed between the two guide rails 20. A discharge hole 22 connected to the inside of the conical grinding groove 2 is opened through the top of the movable block 21, and a discharge pipe 27 matching the discharge hole 22 is fixedly installed at the bottom end of the movable block 21. A discharge groove 23 is opened on the upper surface of the movable block 21 adjacent to the discharge hole 22. A moving mechanism is installed between the movable block 21 and the support ring 5, and the moving mechanism includes two L-shaped rods 25 fixedly installed on the outer surface of the support ring 5, and guide columns 26 are fixedly installed on the outer surface of one side of the movable block 21 at the bottom end of the two L-shaped rods 25. Guide grooves 24 matching the guide columns 26 are opened on the outer surfaces of the opposite sides of the movable block 21, and the guide columns 26 are slidably installed on the inner walls of the guide grooves 24.
[0037] While the support ring 5 moves upward, the guide column 26 will be driven to move vertically upward through the L-shaped rod 25, so that the guide column 26 can push the movable block 21 through the guide groove 24, so that the discharge hole 22 is misaligned with the conical grinding groove 2, and the discharge groove 23 is aligned with the conical grinding groove 2, so that the rice discharged due to the jamming problem can be discharged into a separate collector through the discharge groove 23, so that the jammed rice can be reprocessed later.
[0038] A method for using a rice moderate grinding device comprises the following steps:
[0039] S1: Pour rice into the grinding seat 1 through the feed hopper 18, so that the rice enters the conical grinding groove 2 through the feed pipe 19;
[0040] S2: The driving mechanism drives the grinding cone 8 to rotate, so that the gap between the grinding cone 8 and the conical grinding groove 2 is used to grind the rice. The ground rice enters the discharge hole 22 from the bottom of the grinding seat 1 and is discharged through the discharge pipe 27 to collect the ground rice.
[0041] S3: When material gets stuck between the grinding cone 8 and the conical grinding trough 2, the resistance between the inclined surface of the trapezoidal block 13 and the jamming groove 14 will not be able to overcome the resistance of the grinding cone 8, so that the trapezoidal block 13 will be pushed upward, and the compression spring 15 will be compressed. When the trapezoidal block 13 is pushed upward, the connecting ring 11 will be pushed upward through the guide rod 12, so that the connecting ring 11 contacts the touch switch 16, and the touch switch 16 turns on the electric telescopic rod 4, so that the telescopic end of the electric telescopic rod 4 pulls the support ring 5 upward, so that the support ring 5 can drive the grinding cone 8 to move upward as a whole, so that the gap between the grinding cone 8 and the conical grinding trough 2 becomes larger, and the rice stuck between the grinding cone 8 and the conical grinding trough 2 is quickly discharged.
[0042] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, rice is poured into the grinding seat 1 through the feed hopper 18, so that the rice enters the conical grinding groove 2 through the feed pipe 19; the output end of the driving motor 28 drives the driving shaft 9 to rotate, so that the driving shaft 9 drives the driving disk 10 to rotate, and the driving disk 10 drives the plurality of guide rods 12 and the trapezoidal block 13 to rotate. Since the trapezoidal block 13 is inserted into the card slot 14 in the initial state, under the elastic force of the compression spring 15, the resistance between the inclined surface of the trapezoidal block 13 and the card slot 14 can drive the turntable 6 to rotate, so that the turntable 6 drives the grinding cone 8 to rotate through the connecting shaft 7, so that the gap between the grinding cone 8 and the conical grinding groove 2 can grind the rice, and the ground rice enters the discharge hole 22 from the bottom of the grinding seat 1 and is discharged through the discharge pipe 27, so that the ground rice can be collected;
[0043] When the material is stuck between the grinding cone 8 and the conical grinding groove 2, the resistance between the inclined surface of the trapezoidal block 13 and the groove 14 will not be able to overcome the resistance of the grinding cone 8 to the material being stuck, so that the trapezoidal block 13 will be pushed upward, and the compression spring 15 will be compressed. When the trapezoidal block 13 is pushed upward, the connecting ring 11 will be pushed upward by the guide rod 12, so that the connecting ring 11 contacts the touch switch 16, so that the touch switch 16 turns on the electric telescopic rod 4, so that the telescopic end of the electric telescopic rod 4 pulls the support ring 5 upward, so that the support ring 5 can drive the grinding cone 8 to move upward as a whole, so that the gap between the grinding cone 8 and the conical grinding groove 2 becomes larger, so that the rice stuck between the grinding cone 8 and the conical grinding groove 2 can be quickly discharged, thereby solving the problem of material sticking;
[0044] When the grinding cone 8 is lifted upward, the bottom end of the feed pipe 19 will abut against the top of the grinding cone 8, so that the grinding cone 8 can block the bottom end of the feed pipe 19, preventing the pre-filled rice in the feed hopper 18 from falling and being discharged;
[0045] When the support ring 5 moves upward, the guide post 26 is driven to move vertically upward through the L-shaped rod 25, so that the guide post 26 can push the movable block 21 through the guide groove 24, so that the discharge hole 22 is misaligned with the conical grinding groove 2, and the discharge groove 23 is aligned with the conical grinding groove 2, so that the rice discharged due to the jamming problem can be discharged into a separate collector through the discharge groove 23, so that the jammed rice can be reprocessed later;
[0046] After a certain period of time, the electric telescopic rod 4 automatically drives the grinding cone 8 to reset. At the same time, after the material jamming problem is solved, the trapezoidal block 13 will be stuck into the slot 14 again under the elastic force of the compression spring 15, so that the driving mechanism can drive the grinding cone 8 to rotate again to grind the rice.
[0047] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
