Description

Technical Field

[0001] This utility model belongs to the field of rice technology, specifically, it relates to a movable hopper for rice processing. Background Technology

[0002] Rice is a food made from paddy through cleaning, hulling, milling, and finishing processes. Rice is a staple food for people in most parts of China, containing nearly 64% of the nutrients found in paddy and over 90% of the essential nutrients required by the human body. It is also one of the main grains for the Chinese people. Some existing rice processing hoppers are designed to remove iron-containing impurities.

[0003] Chinese patent CN215465138U discloses a hopper for rice processing, including a hopper body, two baffles, and a sampling mechanism. The two baffles are arranged opposite each other inside the hopper body, and each baffle is hinged to the inner wall of the hopper body at one end away from the other. The hopper body is provided with bolts for adjusting the distance between the two baffles. The sampling mechanism is set on the hopper body. The above-mentioned prior art uses a magnetic attraction mechanism to adsorb metal impurities in rice, but the adsorbed metal impurities can only be removed manually, which is not only troublesome but also easy to cut hands, resulting in low overall efficiency.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a movable hopper for rice processing, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A movable hopper for rice processing includes an inlet hopper and an outlet hopper. The outlet hopper is located below the inlet hopper. A screen roller is installed inside the inlet hopper, and a flap plate is located below the screen roller. A base is located at the center of the outlet hopper, and a rotating seat is located on top of the base. A housing is horizontally mounted through the rotating seat, and an iron core is installed inside the housing. A coil is sleeved around the outer ring of the iron core. A power supply is installed inside the rotating seat. Outlets are located on the front and back of the outlet hopper, and a guide plate is located on the base facing the outlet.

[0008] Optionally, a turntable is provided at the bottom of the rotating seat, and a collection tray is provided inside the discharge hopper on both sides of the rotating seat.

[0009] Optionally, the back of the flip plate is provided with a groove, the groove is provided with a movable shaft, the surface of the movable shaft is sleeved with a connecting shaft, the other side of the connecting shaft is sleeved with a pull rod, the other end of the pull rod is sleeved with a screw, a support block is provided at the center of the screw, and a motor is provided on the front of the feed hopper of the support block.

[0010] Optionally, a material distribution cone is provided on the top of the rotating seat.

[0011] Optionally, the flap must be closed when the rotating seat rotates.

[0012] Optionally, the collection tray has openings on both sides of the discharge hopper, and the collection tray can be pulled out from the openings.

[0013] Optionally, the outer casing is circular.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] 1. This movable hopper for rice processing uses an electromagnetic coil inside the outer shell. When energized, it generates magnetic force, and a flap narrows the feed hopper outlet to ensure that the rice fully contacts the outer shell when poured, thereby adsorbing iron impurities. The outer shell is then transferred to the top of the collection tray by the base rotation. When the power is turned off, the magnetic force disappears, and the iron impurities are collected by the collection tray. The process does not require cleaning of the outer shell, thus achieving automation and improving the overall efficiency of the hopper.

[0016] 2. The movable hopper for rice processing controls the screw rotation via a motor. The pull rods on both sides pull the connecting shaft, which in turn pulls the flaps. Adjusting the distance between the two flaps controls the feeding speed of the discharge hopper, ensuring full contact between the rice husk and the rice. This maximizes the efficiency of the husk in adsorbing impurities. At the same time, it allows for the flaps to be controlled at any time to close the feed hopper outlet and clean impurities from the husk. For rice with more impurities, the frequency of husk cleaning is increased to maintain the best cleaning effect.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figure 1-5 As shown, this embodiment provides a movable hopper for rice processing, including: a feeding bin 1 and a discharging bin 2.

[0030] like Figure 1-5As shown, in this embodiment, a discharge bin 2 is provided below the feed bin 1. A screen roller 21 is installed inside the feed bin 1, and a flap 3 is installed below the screen roller 21. A base 11 is located at the center of the discharge bin 2, and a rotating seat 12 is installed on top of the base 11. A housing 13 is horizontally installed through the rotating seat 12, and an iron core 15 is installed inside the housing 13. A coil 14 is sleeved around the outer ring of the iron core 15. A power supply 16 is installed inside the rotating seat 12. Discharge ports 19 are opened on the front and back of the discharge bin 2, and a guide plate 18 is provided on the base 11 facing the discharge port 19. Rice is fed from the top of the discharge bin 2. In the feed hopper 2, multiple sets of screen rollers 21 can rotate to allow rice to slide through the gaps between the screen rollers 21. The screen rollers 21 first prevent some larger impurities from mixing in and falling. The rice is guided by the flip plate 3 and concentrated to fall to the center. The lower outer shell 13 has a coil 14 installed inside, which is spirally arranged inside the outer shell 13 and connected to the power supply 16 in the rotating seat 12. The iron core 15 amplifies and generates a strong magnetic force to adsorb the iron impurities in the rice that pass through. The rice that cannot be adsorbed falls by gravity and flows out from the discharge ports 19 at both the front and back, completing the impurity removal work of the entire hopper.

[0031] like Figure 4 As shown, in this embodiment, a turntable 17 is provided at the bottom of the rotating base 12, and a collection tray 20 is provided on both sides of the rotating base 12 inside the discharge bin 2. During the continuous impurity removal process of rice, the iron impurities collected on the outer shell 13 will increase. More impurities will reduce the adsorption effect of the outer shell, resulting in a decrease in impurity removal efficiency. At this time, the bottom turntable 17 drives the base 11 to rotate, and the rotating base 12 drives the outer shell 13 to turn. After rotating 90°, the outer shell 13, which was originally located longitudinally in the discharge bin 2, changes to a horizontal position. At this time, the outer shells 13 on both sides extend to the collection tray 20 due to the change in orientation. By turning off the power supply 16, the coil 14 is no longer energized, the magnetic force of the outer shell 13 disappears, and the metal impurities that cannot be adsorbed fall directly from the outer shell 13 into the collection tray 20 below, completing the cleaning of the outer shell 13. Then, the turntable 17 rotates in the opposite direction to make the outer shell 13 return to its original position, and the power supply 16 is energized again to continue the impurity removal process of rice.

[0032] like Figure 1 , 2As shown, the flap 3 in this embodiment has a groove 4 on its back, a movable shaft 5 inside the groove 4, a connecting shaft 6 sleeved on the surface of the movable shaft 5, a pull rod 7 sleeved on the other side of the connecting shaft 6, a screw 8 sleeved on the other end of the pull rod 7, a support block 9 at the center of the screw 8, and a motor 10 on the front of the feed hopper 1 on the support block 9. The threads at both ends of the screw 8 are opposite. The motor 10 drives the screw 8 to rotate by connecting to the screw 8 through the support block 9. The threads on the pull rod 7 and the screw 8 mesh, controlling the two pull rods 7 to move simultaneously in opposite directions. One end of the connecting shaft 6 is sleeved on the pull rod 7, and the other end passes through the movable shaft 5. The two ends of the movable shaft 5 are embedded in the groove 4 and will not disengage. The flap 3 is pulled by the movement of the pull rod 7. The more the pull rod 7 moves to both sides, the wider the flap 3 is opened, the larger the opening, and the faster the rice is poured. Conversely, the speed decreases until it closes. The discharge speed is adjusted by adjusting the opening, and the efficiency is achieved in conjunction with impurity removal.

[0033] like Figure 1-5 As shown, the rotating seat 12 in this embodiment is provided with a dividing cone 22 on the top; wherein, the dividing cone 22 is used to separate the rice poured in the center position to both sides, to prevent some rice from remaining on the rotating seat 12 and being unable to be removed, and finally the rice is guided by the guide plate 18 to be discharged from the discharge port 19.

[0034] like Figure 5 As shown, the flap 3 must be closed when the rotating seat 12 rotates in this embodiment; after a period of time, the surface of the outer shell 13 will adsorb a lot of impurities, affecting the overall adsorption effect. When controlling the turntable 17 to rotate the base 11, the two flaps 3 must be pushed inward to close, the bottom of the feed hopper 1 will be closed, the rice will stop flowing out, and the outer shell 13 cannot remove impurities during the rotation and impurity removal process. It is necessary to stop discharging to avoid affecting the rice production.

[0035] like Figure 1-3 As shown, the collection tray 20 of this embodiment has openings on both sides of the discharge bin 2, and the collection tray 20 can be pulled out from the openings. The collection tray 20 is located on both sides of the base 11, horizontally between the top of the outer shell 13 and the guide plate 18, and does not affect the material receiving of the guide plate 13. When the iron impurities on the outer shell 13 are collected on the collection tray 201, the collection tray 20 can be pulled out from the openings by external personnel, which is convenient for cleaning the collection tray 20.

[0036] like Figure 1 , 2 As shown, the outer shell 13 in this embodiment is circular; the circular surface increases the contact area between the rice and the outer shell 13 when the rice is poured, which improves the adsorption effect and reduces the impact of the rice on the outer shell 13, thus preventing the rice from splashing.

[0037] Working principle: Rice is fed into the discharge bin 2 from the top, passes through the screen roller 21 and is guided by the flap 3. The motor 10 drives the screw 8 to rotate, causing the pull rod 7 to pull the flap 3, thereby adjusting the outlet gap of the feed bin 1 and controlling the falling rate of the rice. At the same time, the power supply 16 supplies power to the coil 14 inside the outer shell 13, causing the coil 14 to generate magnetic force, which attracts the falling rice impurities through the outer shell 13. Then, the turntable 17 controls the base 11 to rotate 90°, the power supply 16 is turned off, the magnetic force of the outer shell 13 disappears, and the metal impurities fall onto the collection tray 20 for collection. The filtered rice is finally discharged from the discharge port 19 through the guide plate 18.
