Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically to a rice processing chaff removal device. Background Technology

[0002] Rice bran is mainly made from the pericarp, seed coat, outer endosperm, aleurone layer and embryo. Therefore, a small amount of rice husks and a certain amount of dust and microorganisms will be mixed in during the processing. So it can only be used as feed and is the main by-product of rice processing.

[0003] The existing Chinese utility model patent with publication number CN219597327U discloses a rice processing bran removal device, including a machine body. The top of the machine body has a feed inlet, one side has a discharge outlet, and the bottom has a discharge outlet. A first fan and a second fan are respectively installed on the other side of the machine body, with the first fan located above the second fan. A hopper is installed inside the feed inlet, and a partition is installed inside the machine body. A collection box and a sliding plate are respectively installed on one side of the partition, with the collection box located above the sliding plate. A first dividing opening and a second dividing opening are respectively opened through one side of the partition, with the first dividing opening located above the second dividing opening. By using the first fan and the first dividing opening in conjunction, the working efficiency can be improved to a certain extent. Specifically, when the material enters the machine body from the hopper, utilizing the principle that rice is relatively heavy, the first fan blows the rice bran away from the material, eliminating the need for a filter screen and saving time spent cleaning the filter screen.

[0004] The aforementioned rice bran removal equipment uses a sliding plate to control the speed at which the rice falls, and then uses an airflow generated by a fan to blow the airflow towards the area where the rice falls, thereby removing the rice bran. Because the sliding direction of the sliding plate is perpendicular to the airflow direction, the rice falls in a curtain-like pattern, and the area covered by the airflow is much larger than the area covered by the falling rice, resulting in low efficiency. At the same time, the rice bran is directly discharged under the influence of the airflow, making it impossible to collect the removed rice bran, which affects the rice bran recycling work.

[0015] Beneficial effects

[0016] This utility model provides a rice processing hull removal device. Compared with the prior art, it has the following advantages:

[0017] (1) The rice processing de-branching device uses an elevator to move the rice into the connecting pipe. The connecting pipe guides the rice into the interior of the guide pipe and discharges it downward through the pentagonal opening structure at the bottom of the guide pipe. Since the center line of the opening structure at the bottom of the guide pipe is a pentagon, and the center of one opening structure at the vertex of the pentagon is located on the longitudinal section of the guide pipe, and the remaining four opening structures are symmetrical from left to right, this distribution method can make the movement path of the rice during the falling process cover most of the vertical tubular structure in the center of the shell, thereby improving the de-branching efficiency.

[0018] (2) The rice processing bran removal device uses a filter bag, which is placed inside the collection tube. The collection tube is located on the right side of the outer shell. The drive motor can drive the fan blade to rotate and generate airflow towards the central tubular structure of the outer shell. The airflow drives the rice bran to move to the right and into the filter bag inside the collection tube. Since the gas delivery volume of the air pump is much greater than that of the fan blade, some air will enter the outer shell from the bottom of the central tubular structure, preventing the rice bran from being discharged with the rice at the bottom of the central tubular structure. At the same time, the air pump can extract the airflow inside the collection tube so that the filter bag can collect the rice bran. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a rice processing hulling device, comprising a support frame 1, and a hulling removal mechanism 2 disposed above the support frame 1.

[0028] The lifting assembly 21 includes a lifting machine 211. A connecting pipe 212 is fixedly installed at the top of the lifting machine 211. A guide pipe 213 is fixedly installed below the connecting pipe 212. A connecting bearing 214 is fixedly installed inside the guide pipe 213. A transmission pipe 215 is inserted through the outside of the connecting bearing 214. A limit plate 216 is inserted through the center of the guide pipe 213. The front side of the connecting pipe 212 communicates with the top of the lifting machine 211. The bottom of the guide pipe 213 has five openings arranged in a pentagonal pattern with the center of the guide pipe 213 as the reference. The bottom of the guide tube 213 is funnel-shaped, and a cylindrical tubular structure with a conical top is provided at the center of the inner cavity of the guide tube 213. The connecting bearing 214 is fixed to the outside of the cylindrical part of the central protrusion of the guide tube 213. A baffle structure is provided at the bottom of the transmission tube 215. The limiting plate 216 passes through the tubular structure at the center of the guide tube 213 and forms a rotatable connection with the guide tube 213 through the bearing. The bottom of the limiting plate 216 is disc-shaped, and the surface is provided with an opening structure that is consistent with the number, position and size of the openings at the bottom of the guide tube 213.

[0029] Specifically, the support frame 1 restricts the position of the outer shell 231. The hoist 211 moves the rice into the connecting pipe 212, which guides the rice into the interior of the guide pipe 213. The rice is discharged downward through the pentagonal openings at the bottom of the guide pipe 213. Since the center line of the openings at the bottom of the guide pipe 213 is a pentagon, and the center of one opening at the vertex of the pentagon is located on the longitudinal section of the guide pipe 213, and the remaining four openings are symmetrical, this distribution allows the rice to cover most of the vertical tubular structure at the center of the outer shell 231 during its descent, thereby improving the bran removal efficiency. The feeding speed is adjusted by adjusting the overlapping area between the openings of the limiting plate 216 and the openings of the guide pipe 213. The transmission pipe 215 can move the rice when rotating, preventing the rice from becoming clogged.

[0030] The drive assembly 22, located at the top of the lifting assembly 21, is used to control the feeding speed. The drive assembly 22 includes a fixed frame 221 fixedly installed at the top of the connecting pipe 212. An end gear 222 is mounted on the bottom surface of the top plate of the fixed frame 221 via bearings. A bevel gear 223 is movably installed on one side of the fixed frame 221. A drive motor 224 is fixedly installed on one side of the top of the fixed frame 221. A drive gear 225 is fixedly installed on the outer side of the shaft of the drive motor 224. A direct drive motor 226 is fixedly installed at the center of the fixed frame 221. The center of the fixed frame 221 is... It has a downward-extending tubular structure. The end gear 222 is mounted on the bottom end of the tubular structure of the fixed frame 221 by bearings. The shaft of the direct drive motor 226 is fixedly connected to the top end of the cylindrical structure in the center of the limiting plate 216. The end gear 222 is also fixedly mounted on the top end of the transmission tube 215 and is mirror-symmetrical with the end gear 222 on the top of the fixed frame 221. The end gears 222 are connected by bevel gears 223. The outer side of the end gear 222 is provided with a toothed structure. The transmission gear 225 meshes with the outer toothed structure of the end gear 222 on the top of the fixed frame 221.

[0031] Specifically, the fixed frame 221 can restrict the position of the upper end gear 222 and the bevel gear 223. The drive motor 224 can drive the drive gear 225 to rotate, and the drive gear 225 drives the upper end gear 222 to rotate. When the end gear 222 at the top of the fixed frame 221 rotates, it can drive the end gear 222 at the top of the drive tube 215 to rotate through the bevel gear 223, thereby driving the drive tube 215 to rotate. The shaft of the direct drive motor 226 passes through the central opening structure of the fixed frame 221 and is fixedly connected to the top of the columnar structure at the center of the limiting plate 216. The direct drive motor 226 drives the limiting plate 216 to rotate, and the rotation angle of the limiting plate 216 is adjusted to control the feeding speed.

[0032] The collection component 23 is located below the lifting component 21 and removes rice bran through airflow. The collection component 23 includes a housing 231 fixedly installed inside the support frame 1. A drive motor 232 is fixedly installed inside the housing 231. A fan blade 233 is fixedly installed on the outside of the shaft of the drive motor 232. A grid plate 234 is fixedly installed on the left end of the housing 231. A collection pipe 235 is movably installed on the lower right side of the housing 231. A filter bag 236 is fitted inside the collection pipe 235. An air pump 237 is fixedly installed on the right side of the collection pipe 235. The air outlet direction of the fan blade 233 is horizontal to the right. The top end of the rectangular tubular structure in the center of the housing 231 is fixedly connected to the bottom end of the guide pipe 213. An annular protrusion is provided on the upper inside of the collection pipe 235 to fit with the filter bag 236. The filter bag 236 is cylindrical and has an annular metal structure on the outer side of its top end. The air inlet end of the air pump 237 is connected to the housing 231.

[0033] Specifically, the outer shell 231 can restrict airflow through the space where rice falls, the drive motor 232 can drive the fan blade 233 to rotate and generate airflow towards the central tubular structure of the outer shell 231, the grid plate 234 can facilitate air intake, the collection pipe 235 can restrict the position of the filter bag 236 and capture rice bran through the filter bag 236, and the air pump 237 can extract the airflow inside the collection pipe 235 so that the filter bag 236 can collect rice bran. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0034] During operation, the rice is moved into the connecting pipe 212 by the elevator 211. The connecting pipe 212 guides the rice into the guide pipe 213, where it is discharged downwards through the pentagonal perforated structure at the bottom of the guide pipe 213. Because the center line connecting the perforations at the bottom of the guide pipe 213 forms a pentagon, and the center of one perforation at a vertex of the pentagon is located on the longitudinal section of the guide pipe 213, while the remaining four perforations are symmetrical, this distribution ensures that the rice's path during descent covers most of the vertical tubular structure at the center of the outer shell 231, thereby improving the bran removal efficiency. The filter bag 236 is equipped with... Inside the collection tube 235, which is located on the right side of the outer casing 231, the drive motor 232 can drive the fan blade 233 to rotate and generate airflow towards the central tubular structure of the outer casing 231. The airflow drives the rice bran to move to the right and into the filter bag 236 inside the collection tube 235. Since the gas delivery volume of the air pump 237 is much greater than that of the fan blade 233, some air will enter the outer casing 231 from the bottom of the central tubular structure, preventing the rice bran from being discharged with the rice at the bottom of the central tubular structure of the outer casing 231. At the same time, the air pump 237 can extract the airflow inside the collection tube 235 so that the filter bag 236 can collect the rice bran.
