Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a brown rice separation device for rice processing. Background Technology

[0002] In rice processing, the separation of brown rice and white rice is a crucial step. Its purpose is to effectively separate the brown rice and white rice (polished rice) that are mixed together after milling. Existing brown rice separation equipment, such as bag-type or flat-plate type brown rice separators, usually achieves separation through the principle of vibrating sieving or friction separation. The separated rice grains are discharged through different discharge hoppers.

[0003] However, in actual production, the discharge port position is fixed and the height is not adjustable. When receiving containers of different heights are used, the fixed discharge port may cause the material to fall too high. The rice grains impact the bottom of the container or the pile of rice at a high speed, causing the rice grains to splash, break, and be wasted. This not only increases the cleaning burden on workers and affects the working environment, but also causes material loss. In addition, when changing the receiving container, it is inconvenient to stop the discharge and leakage is likely to occur during the interval.

[0004] To address these issues, we propose a brown rice separation device for paddy processing. Utility Model Content

[0005] The purpose of this invention is to provide a brown rice separation device for paddy processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A brown rice separation device for paddy processing includes a frame, a vibration system, a screen, a feed hopper, and a discharge hopper. An extension tube is slidably connected to the lower part of the discharge hopper. A connecting seat is fixed to the outer wall of the upper section of the extension tube. An electric push rod is installed on the outer wall of the discharge hopper to drive the extension tube to move up and down. The output end of the electric push rod is connected to the connecting seat. A baffle is slidably connected inside the lower section of the extension tube. A connecting plate is provided at one end of the baffle that extends out of the outer wall of the extension tube. An electric push rod is installed on the outer wall of the extension tube to drive the baffle to slide. The output end of the electric push rod is connected to the connecting plate.

[0007] In a further embodiment, a pair of symmetrical protrusions are provided on the outer wall of the discharge hopper, and a groove is provided on the inner wall of the extension tube corresponding to each protrusion, and the protrusions slide into the groove.

[0008] In a further embodiment, corrugated telescopic sleeves are fitted over the output sections of both the electric push rod one and the electric push rod two.

[0009] In a further embodiment, the end of the baffle near the connecting plate is higher than the other end, forming an inclined structure.

[0010] In a further embodiment, a baffle is provided on the inner wall of the extension tube, and when the baffle is closed, the lower edge of the baffle abuts against the baffle.

[0011] In a further embodiment, the upper surface of the baffle platform adopts an inclined surface structure opposite to the inclination direction of the baffle.

[0012] In a further embodiment, distance sensors are installed at both the upper and lower ends of the outer wall of the extension tube, and electric push rod one, electric push rod two, and distance sensors are all electrically connected to a central controller.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention, by setting up a height-adjustable extension tube, can flexibly adjust the distance between the discharge port and the material accumulation surface according to the height of the receiving container, which greatly reduces the impact force of falling rice grains, fundamentally solves the problems of rice grain splashing and breakage caused by collision, reduces material loss, and improves the working environment.

[0014] This invention enables rapid opening and closing of the discharge port by installing a baffle inside the extension tube controlled by an electric push rod. When changing the receiving container, the baffle can be closed in time to prevent material leakage, and the port can be opened quickly after preparation. The operation is simple and efficient, avoiding material waste. Attached Figure Description

[0017] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 A brown rice separation device for paddy processing includes a frame 1, a vibration system 2, a screen body 3, a feed hopper 4, and a discharge hopper 5. The screen body 3 and the vibration system 2 are mounted on the frame 1. The screen body 3 has multiple layers of separation plates with specific bag holes or rough surfaces inside. The vibration system 2 can be driven by an eccentric shaft mechanism by a motor. The feed hopper 4 is installed above the screen body 3, and the discharge hopper 5 is connected to the side of the screen body 3. The improvement of this utility model lies in the discharge control device below the discharge hopper 5.

[0021] An extension tube 6 is slidably connected to the lower end of the discharge hopper 5. To achieve stable lifting and lowering, a pair of protruding strips 51 are symmetrically fixed on the outer wall of the discharge hopper 5. Correspondingly, a pair of grooves 61 matching the protruding strips 51 are opened on the inner wall of the extension tube 6. The protruding strips 51 are embedded in the grooves 61 to form a torsion-resistant sliding pair, ensuring that the extension tube 6 can only lift and lower smoothly in the vertical direction without rotation.

[0022] The lifting and lowering of the extension tube 6 is driven by an electric push rod 8. The cylinder of the electric push rod 8 is fixed on the outer wall of the discharge hopper 5, and its output end is connected to a connecting seat 7 fixed on the upper outer wall of the extension tube 6. By extending and retracting the electric push rod 8, the extension tube 6 can be driven to slide up and down along the guide of the protrusion 51, thereby adjusting the final height of the discharge port.

[0023] Inside the lower section of the extension tube 6, a baffle 9 is slidably installed. One end of the baffle 9 extends out of the tube wall of the extension tube 6 and is fixed to a connecting plate 10. The sliding of the baffle 9 is driven by an electric push rod 11. The cylinder of the electric push rod 11 is fixed to the outer wall of the extension tube 6, and its output end is connected to the connecting plate 10. By extending and retracting the electric push rod 11, the baffle 9 can be controlled to extend into or out of the inner cavity of the extension tube 6, thereby realizing the closing and opening of the discharge port.

[0024] Specifically, the baffle 9 itself is designed as an inclined structure, that is, the end near the connecting plate 10 is higher and the other end is lower. At the same time, a baffle 62 is fixed on the inner wall of the extension tube 6. When the electric push rod 11 pushes the baffle 9 to the closed position, the lower edge of the baffle 9 just abuts against the baffle 62. Preferably, the upper surface of the baffle 62 is also processed into an inclined surface opposite to the inclined direction of the baffle 9, which facilitates guiding the rice grains down and reducing residue.

[0025] Both the output rods of electric push rod 18 and electric push rod 21 are fitted with corrugated telescopic sleeves 12. The two ends of the corrugated telescopic sleeves 12 are fixed to the cylinder body and the connecting plate 10 / connecting seat 7 respectively, which effectively prevents rice bran dust from entering the push rod and extends the service life of the push rod.

[0026] Distance sensors 13 are installed at the upper and lower ends of the outer wall of the extension tube 6 to detect the height of the receiving container and the material accumulation height. Electric push rod 1 8, electric push rod 2 11 and distance sensors 13 are all electrically connected to a central controller (not shown in the figure) to realize automated control.

[0027] Workflow: After the equipment is powered on, the central controller starts. The distance sensor 13 at the bottom detects the height of the receiving container. The central controller controls the electric push rod 8 to move, lowering the extension tube 6 to a suitable height so that the discharge port is as close as possible to the bottom of the container. After separation, the rice grains fall from the discharge hopper 5. The central controller controls the electric push rod 11 to retract, pulling the baffle 9 out of the inner cavity of the extension tube 6, opening the channel, and the rice grains flow out smoothly through the extension tube 6. The distance sensor 13 at the top can monitor the height of the material accumulation surface in real time. When the material pile rises, the controller can automatically control the electric push rod 8 to appropriately raise the extension tube 6 to always maintain a reasonable drop difference and prevent splashing. When a container is full and needs to be replaced, the controller first controls the electric push rod 11 to push out, pushing the baffle 9 to close the channel and cut off the rice flow. After replacing the empty container, the discharge can continue.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
