[0002] Rice is obtained by husking rice grains. Rice grains are composed of husk, cortex, embryo and endosperm. The purpose of rice processing is to separate the endosperm from other parts with the least degree of crushing to make rice with better edible quality. Rice processing is divided into impurity removal, rice husking, rice-rough separation, rice milling, polishing, grading, color sorting, quantitative packaging and warehousing. During rice milling, the brown rice after ridged rice is fed into the rice mill through the feeding device for milling. When the grains are ridged, a small amount of metal powder will adhere to the brown rice.

[0003] In the existing technology, in order to ensure the purity of rice and prevent metal impurities from affecting subsequent processing procedures, a strong magnetic plate is usually installed in front of the feed port of the rice mill to absorb metal debris in the rice. This method requires manual cleaning of the magnetic plate on a regular basis, which increases additional labor costs and is more troublesome.

[0004] Therefore, the present invention provides a rice milling machine feeding mechanism to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides a feeding mechanism for a rice mill, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the feeding mechanism includes a storage hopper 1, a discharge plate 2 fixedly installed inside the storage hopper 1, a connecting frame 3 fixedly installed at the bottom of the storage hopper 1, a movable plate 7 slidably installed at the bottom of the discharge plate 2, an electromagnetic suction cup 11 fixedly installed at the bottom of the movable plate 7 for absorbing debris in rice, a collecting box 12 arranged inside the connecting frame 3 for receiving debris, a discharge mechanism fixedly installed at the bottom of the discharge plate 2 for rice discharge, and a moving mechanism fixedly installed inside the connecting frame 3 for moving the collecting box 12.

[0024] The blanking mechanism includes a fixed block 9 fixedly installed at the bottom of the blanking plate 2, a limiting rod 19 fixedly installed on the fixed block 9, and a moving block 8 slidably installed on the limiting rod 19. One side of the moving block 8 is fixedly connected to one side of the moving plate 7.

[0025] The blanking plate 2 is provided with a blanking notch, and the movable plate 7 and the electromagnetic chuck 11 are provided with the same blanking notch as that on the blanking plate 2 .

[0026] A strip slot is provided on the connecting frame 3 , and the connecting strip 15 is movably connected to the inside of the strip slot. The bottom of the connecting frame 3 is fixedly connected to the discharge hopper 4 , and the inner cavity of the discharge hopper 4 is connected to the inner cavity of the storage hopper 1 through the connecting frame 3 .

[0027] The discharge hopper 4 of the feeding mechanism is connected to the feeding port of the rice mill, and the rice to be processed is placed in the storage hopper 1. The discharge plate 2 inside the storage hopper 1 is provided with a discharge slot, and the movable plate 7 and the electromagnetic suction cup 11 are provided with the same slot. Two situations can occur when the movable plate 7 moves with the electromagnetic suction cup 11. The first is that the slots of the three will overlap, so that the rice can pass smoothly. The second is that the movable plate 7 closes the slot on the discharge plate 2 so that the rice cannot fall. When the rice is discharged, the electromagnetic suction cup 11 needs to be energized. When the rice passes through the slot on the electromagnetic suction cup 11, the electromagnetic suction cup 11 can absorb the debris in the rice. At the same time, the amount of discharge can be controlled by controlling the moving interval of the movable plate 7.

[0028] The collecting box 12 is arranged directly below the electromagnetic suction cup 11. The chamber in the collecting box 12 corresponds to the notch of the electromagnetic suction cup 11. In addition, the collecting box 12 is also provided with a notch corresponding to the notch of the electromagnetic suction cup 11 to ensure that the rice can fall into the discharge hopper 4. When the movable plate 7 carries the electromagnetic suction cup 11 to close the discharge plate 2, the electromagnetic suction cup 11 can be powered off. At this time, the collecting box 12 can receive the debris dropped from the electromagnetic suction cup 11.

[0029] Furthermore, in order to facilitate the disposal of debris adsorbed on the electromagnetic chuck 11, as Figure 2 、 Figure 3 and Figure 4 As shown, the movement includes a slide rail 17 fixedly installed inside the connecting frame 3, a slider 18 slidably installed inside the slide rail 17, and a slide bar 13 slidably installed on the top of the slide rail 17. The top of the slider 18 is fixedly connected to the bottom of the slide bar 13, and the collection box 12 is movably connected to the top of the slide bar 13.

[0030] The slide bar 13 can slide stably on the slide rail 17 through the slider 18. The collection box 12 is arranged on the slide bar 13 to facilitate the staff to take the collection box 12 and clean up the debris.

[0031] Furthermore, in order to facilitate the use of the collection box 12 by the staff, as shown in FIG. Figure 2 and Figure 4 As shown, the moving mechanism also includes a clamping bar 14 fixedly mounted on the top of the slide bar 13 for clamping the collection box 12, a connecting bar 15 fixedly mounted on one side of the slide bar 13, and a handle 16 fixedly mounted on the side of the connecting bar 15 away from the slide bar 13. One side of the clamping bar 14 is fixedly connected to the side of the connecting bar 15 close to the slide bar 13.

[0032] The clamping strip 14 is provided to stabilize the collection box 12 and ensure that the position of the collection box 12 will not be offset. The staff can move the collection box 12 out of the inside of the feeding mechanism through the handle 16, which improves the convenience of the staff in using the collection box 12.

[0033] In order to reduce the vibration of the moving plate 7 during operation, Figure 2 and Figure 3 As shown, a spring 10 is sleeved on the limiting rod 19 , one end of the spring 10 is fixedly connected to one side of the moving block 8 , and the other end of the spring 10 is fixedly connected to one side of the fixed block 9 .

[0034] The setting of the spring 10 provides a certain buffer force when the moving plate 7 and the moving block 8 reciprocate on the limiting rod 19, thereby reducing vibration and increasing the service life of the feeding mechanism.

[0035] It should be noted that, in order to enable the movable plate 7 to move, Figure 2 、 Figure 3 and Figure 4 As shown, the connecting frame 3 is fixedly connected to a mounting platform 5, the mounting platform 5 is fixedly connected to a telescopic cylinder 6, a slot is provided on the connecting frame 3, and the movable end of the telescopic cylinder 6 is fixedly connected to one side of the movable plate 7 through the slot.

[0036] The movable end of the telescopic cylinder 6 is connected to the movable plate 7 so that the movable plate 7 can move and thus realize the control of the blanking of the blanking plate 2.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
