Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rice processing, and specifically relates to a feeding pretreatment device for rice. Background Art
[0002] Polishing is an important process in the fine processing of rice. The essence of rice polishing is a humidifying and rubbing separation process. After the hundred-meter rice meets certain accuracy requirements, it is wetted by adding water and then polished, so that the rice grains are crystal clear, do not adhere to bran powder, and do not shed rice powder, thereby improving its storage performance and enhancing its commercial value.
[0003] Before rice processing, pretreatment is required to screen out impurities, broken rice or rice bran in the rice. For example, the Chinese utility model patent CN206500193U discloses a rice polishing pretreatment device. The rice to be processed enters the interior of the machine body from the feeding funnel, and the feeding speed of the rice can be adjusted through the feeding speed regulator. Secondly, the rice falls onto the vibrating filter screen. The vibrating motor is turned on to make the vibrating filter screen vibrate continuously. The rice grains continuously fall downward into the lower end of the machine body. After being brushed by the spiral brush cloth on the first cleaning device and then fully brushed by the cleaning brush on the second cleaning device, the bran powder on the surface of the rice grains falls off. The cleaned rice slides leftward from the inclined filter screen and is discharged from the discharge door. The brushed bran powder and broken rice slide downward from the inclined filter screen into the conical discharge hopper and are discharged through the discharge port for subsequent utilization. The pretreatment of rice polishing ends, and the rice discharged from the discharge door can be polished.
[0004] The above-mentioned prior art cleans the rice grains through a cleaning brush. This method is likely to cause bran to stick to the cleaning brush. If not cleaned in time, the impurities on the cleaning brush are likely to adhere to the surface of the subsequent incoming rice grains, resulting in poor cleaning effect. Summary of the Utility Model
[0005] The purpose of this part is to outline some aspects of the embodiments of the present utility model and briefly introduce some preferred embodiments. In this part, as well as in the abstract and the title of the specification of this application, some simplifications or omissions may be made to avoid obscuring the purpose of this part, the abstract of the specification and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present utility model.
[0006] To solve the above problems, the present utility model adopts the following technical solutions.
[0007] A feeding pretreatment device for rice, comprising a pretreatment box. A discharge port is arranged at the bottom of the pretreatment box. A filter plate is installed on the inner wall of the pretreatment box. Above the filter plate is a placement bin. Rice is placed inside the placement bin and filtered through the filter plate. A first fan is embedded and installed on an outer wall of one side of the pretreatment box. A diversion pipe is detachably connected at a relative position on the other side of the pretreatment box. The diversion pipe is communicated with the inside of the pretreatment box. A filter bag assembly is inserted into an outer wall of the diversion pipe near the bottom. The first fan blows air from the outside into the inside of the pretreatment box, and the rice bran on the rice enters the inside of the diversion pipe and is filtered by the filter bag assembly.
[0008] Preferably, a second fan is detachably connected to an end of the diversion pipe near the lower part. The second fan pumps the air inside the pretreatment box outwards.
[0009] Preferably, sliding grooves are arranged on inner walls of both sides of the pretreatment box above the filter plate. A sliding plate body is slidably connected inside the sliding grooves. A material discharge port is arranged on the sliding plate body. A driving mechanism is installed on an outer wall of the pretreatment box. The driving mechanism enables the sliding plate body to move left and right cyclically inside the sliding grooves. The rice falls above the filter plate through the material discharge port for filtering.
[0010] Preferably, inclined surfaces inclined inwards are arranged on four sides of the material discharge port near the upper part. The rice enters the inside of the material discharge port through the inclined surfaces.
[0011] Preferably, inclined plates are arranged at positions on the inner wall of the pretreatment box above the sliding grooves on both sides. The inclined plates can stay above the sliding plate body through the inclined plates when the sliding plate body moves.
[0012] Preferably, the driving mechanism includes a driving motor, a winding roller and a steel wire rope. The driving motor is embedded and installed on the outer wall of the pretreatment box. A winding roller is detachably connected to a rotating end of the driving motor. Limit plates are detachably connected to both ends of the sliding plate body. The two limit plates can limit the moving stroke of the sliding plate body. A steel wire rope is connected to the outside of one limit plate. The steel wire rope is wound around the outer wall of the winding roller and connected to the other limit plate. The driving motor rotates to drive the winding roller to rotate, and thus the steel wire rope near one limit plate can be wound and the other side can be lengthened, driving the sliding plate body to slide left and right cyclically.
[0013] Preferably, impurity discharge grooves are arranged on outer walls of both sides of the pretreatment box between the sliding plate body and the filter plate. Electric telescopic rods are detachably connected to bottoms of both sides of the sliding plate body at positions on both sides of the material discharge port. Bottoms of the two electric telescopic rods are detachably connected to a horizontal side of an L-shaped pushing plate. Vertical sides of the two L-shaped pushing plates are located at positions far from the two electric telescopic rods. When the sliding plate body moves to an inner wall of one side of the pretreatment box and moves towards the other side, the electric telescopic rod in the advancing direction of the sliding plate body extends, so that the horizontal side of the L-shaped pushing plate contacts above the filter plate.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] 1. The first blower is arranged to blow the lighter impurities such as rice bran on the rice into the inside of the diversion pipe and filter them through the filter bag assembly. The filter bag assembly can be taken out by plugging to complete the cleaning. Through the suction of the filter bag assembly, the cleaning effect can be better, and the rice falling downward forms a vertical surface due to the movement of the sliding plate body, thereby improving the cleaning effect.
[0016] 2. The driving motor is arranged to drive the winding roller to rotate, so that the steel wire rope near one side limiting plate is wound and the other side is lengthened, thereby enabling the sliding plate body to slide left and right cyclically. Through the forward and reverse reciprocating rotation of the driving motor, the sliding plate body can slide left and right reciprocally inside the two sliding grooves. Cooperating with the feeding port, the rice falls above the filter plate for filtering, and the position of the feeding port relative to the filter plate is changed due to the sliding of the sliding plate body, so that the rice can be evenly placed above the filter plate, thereby increasing the filtering effect.
[0017] 3. The inclined plate is arranged to stay above the sliding plate body through the inclined plate when the sliding plate body moves, preventing it from falling to the outside. Description of the Drawings

[0027] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manners of the present utility model with reference to the accompanying drawings of the specification.
[0028] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments. The present utility model provides the following embodiments.
[0030] As Figure 1 and Figure 2 shown, it is a schematic structural diagram of a rice feeding pretreatment device according to a preferred embodiment of the present utility model. The rice feeding pretreatment device of this embodiment includes a pretreatment box 100. A discharge port 105 is provided at the bottom of the pretreatment box 100. A filter plate 102 is detachably connected to the inner wall of the pretreatment box 100. Above the filter plate 102 is a placement bin 101. Rice is poured above the filter plate 102 and after being screened by the filter plate 102, the rice grains are discharged and collected through the discharge port 105.
[0031] As Figure 2 and Figure 3 shown, it is a schematic diagram of the cross-section of the pretreatment box and the sliding plate body structure in this embodiment. On both inner walls of the pretreatment box 100 above the filter plate 102, sliding grooves 103 are provided. A sliding plate body 200 is slidably connected inside the sliding grooves 103. A material discharge port 202 is provided on the sliding plate body 200. The four sides of the material discharge port 202 near the upper part are provided with inclined surfaces that incline inward. The inclined surfaces make it easier for the rice to enter the inside of the material discharge port 202. In this embodiment, when the rice is inside the placement bin 101, it falls above the filter plate 102 through the material discharge port 202 for filtering, and by sliding the sliding plate body 200, the position of the material discharge port 202 relative to the filter plate 102 is changed, so that the rice can be evenly placed above the filter plate 102, thereby increasing the filtering effect.
[0032] As shown Figure 2 In the present embodiment, in order to enable the sliding plate body 200 to slide, a driving motor 203 is embedded and installed on the outer wall of the pretreatment tank 100. The rotating end of the driving motor 203 is detachably connected to a winding roller 204. The two ends of the sliding plate body 200 are detachably connected with limiting plates 201. The two limiting plates 201 on both sides can limit the moving stroke of the sliding plate body 200. A steel wire rope 205 is connected to the outside of one limiting plate 201. The steel wire rope 205 is wound around the outer wall of the winding roller 204 and connected to the other limiting plate 201. In the present embodiment, the driving motor 203 rotates to drive the winding roller 204 to rotate, so that the steel wire rope 205 close to one limiting plate 201 is wound up and the other side is lengthened, thereby enabling the sliding plate body 200 to slide circularly left and right. By the forward and reverse reciprocating rotation of the driving motor 203, the sliding plate body 200 can reciprocate left and right inside the two sliding grooves 103.
[0033] It should be noted that the above driving motor 203, winding roller 204 and steel wire rope 205 are the reciprocating mechanism in the present embodiment. The reciprocating mechanism includes but is not limited to the driving motor 203, winding roller 204 and steel wire rope 205. As long as it can make the sliding plate body 200 reciprocate left and right inside the sliding groove 103, the mechanism can be applied to the present embodiment.
[0034] As shown Figure 2 In the present embodiment, in order to prevent the rice from falling out from the sliding groove 103 when the sliding plate body 200 moves, inclined plates 106 are arranged at the positions on the inner wall of the pretreatment tank 100 above the two sliding grooves 103 on both sides. The inclined plates 106 can stay above the sliding plate body 200 through the inclined plates 106 when the sliding plate body 200 moves, preventing it from falling outwards.
[0035] As shown Figure 2 And Figure 4 As shown, it is a schematic structural diagram of the pretreatment tank and the L-shaped pushing plate in the present embodiment. Impurity discharge grooves 104 are arranged on both outer walls of the pretreatment tank 100 between the sliding plate body 200 and the filter plate 102. Electric telescopic rods 206 are detachably connected to the bottoms on both sides of the lower material port 202 at the bottom of the sliding plate body 200. The bottoms of the two electric telescopic rods 206 are detachably connected to the horizontal sides of an L-shaped pushing plate 207. The vertical sides of the two L-shaped pushing plates 207 are located at positions far from the two electric telescopic rods 206. In the present embodiment, when the sliding plate body 200 moves to one inner wall of the pretreatment tank 100 and moves to the other side, the electric telescopic rod 206 in the advancing direction of the sliding plate body 200 extends, so that the horizontal side of the L-shaped pushing plate 207 contacts the upper part of the filter plate 102, and then the filtered impurities can be pushed out from the impurity discharge groove 104, thereby automatically cleaning the filtered impurities.
[0036] As shownFigure 5 As shown in the figure, it is a schematic structural diagram of the filter bag assembly in this embodiment. A first fan 300 is embedded and installed on one outer wall of the pretreatment tank 100. A diversion pipe 301 is detachably connected to the opposite position on the other side of the pretreatment tank 100. The diversion pipe 301 is communicated with the inside of the pretreatment tank 100. A filter bag assembly 302 is inserted into the outer wall of the diversion pipe 301 near the bottom. A second fan 303 is detachably connected to the end of the diversion pipe 301 near the bottom. The first fan 300 blows air into the inside of the pretreatment tank 100, and the second fan 303 sucks air to the outside. In this embodiment of the city, the filtered rice falls downward. The first fan 300 blows air to blow the lighter impurities such as rice bran on the rice into the inside of the diversion pipe 301 and filters them through the filter bag assembly 302. The filter bag assembly 302 can be taken out by plugging to complete the cleaning. Through the air extraction of the filter bag assembly 302, the cleaning effect can be better, and the movement of the sliding plate body 200 is coordinated to make the rice falling downward fall vertically, thereby improving the cleaning effect.
[0037] The above content further elaborates on the present invention in combination with specific implementation manners. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope determined by the claims submitted for the present invention.
