[0013] The present invention provides a rice conveying and bran removing device, which has the following beneficial effects: 1. The present invention sets a conveying mechanism to transmit the rice to the left side of the second baffle through the gap between the second baffle and the conveyor, so that the rice after passing through the second baffle will be evenly spread on the conveyor, and then naturally fall into the external bran remover, ensuring that the rice received by the bran remover is stable and uniform, and also making the working efficiency of the bran remover stable, thereby improving the quality of the rice after bran removal.

[0014] 2. The present invention provides a conveying mechanism to ensure that the unevenly transported rice above the conveyor can not only be kept uniform, but also can utilize the space between the bottom of the second baffle and the through groove to ensure that a sufficient amount of rice can pass through the second baffle, thereby avoiding the problem of insufficient rice transportation volume caused by the need to flatten the rice and the short distance between the second baffle and the conveyor.

The movement of the soft hair can effectively break up the rice pile and fully spread the rice, so that the rice can pass through the bottom of the connecting rod more evenly and efficiently.

[0018] 6. The present invention provides an auxiliary mechanism. Even if the second baffle is lifted, the roller can stably contact with the conveyor surface and be driven to rotate the connecting rod and the stirring bristles together to complete the function of rotating and stirring the rice, thereby ensuring that the rice can be moved by the stirring bristles under various working conditions, thereby ensuring its stable transportation.

DETAILED DESCRIPTION

[0021] Example 1: Please refer to Figure 1-3 , the present invention provides a technical solution: a rice conveying and bran removing device, comprising a supporting leg 1, a conveyor 2 is arranged on the top of the supporting leg 1, and a conveying mechanism 3 is arranged on the top of the conveyor 2; The conveying mechanism 3 comprises: A first baffle 301, which is a strip-shaped plate structure, is fixedly connected to the top of the conveyor 2, a bearing sleeve 302 is fixedly connected to one side of the first baffle 301, and a rotating rod 303 is fixedly connected to the inner wall of the bearing sleeve 302, and the rotating rod 303 is a round rod-shaped structure. The first baffle 301 is used to prevent the rice on the conveyor 2 from falling; The second baffle 304 is a square plate structure. The top of the second baffle 304 is fixedly connected to the outer wall of the rotating rod 303. A gap is formed between the second baffle 304 and the conveyor 2, and the gap is used to allow rice to pass through and play a role in transmission; When in use, a large amount of rice is poured onto the conveyor 2, and then the conveyor 2 is started to transfer the rice to the left side, and the rice naturally falls to the external bran remover through the left side, and the rice is transported and bran removed by the external bran remover; During the conveying process, the rice will pass through the bottom of the second baffle 304. There is a horizontal gap between the bottom of the second baffle 304 and the conveyor 2, so that when the rice passes through the bottom of the second baffle 304, it will be transmitted to the left side of the second baffle 304 through the gap between the second baffle 304 and the conveyor 2, so that the rice after passing through the second baffle 304 will be evenly spread on the conveyor 2, and then naturally fall into the external bran remover, ensuring that the rice received by the bran remover is stable and uniform, and also making the bran remover work more efficiently, thereby improving the quality of the rice after the bran is removed; Example 2: Please refer to Figure 1-8 On the basis of the first embodiment, the present invention provides a technical solution: a through groove 305 is provided on the inner wall of the second baffle 304, and the through groove 305 is a long strip-shaped groove, and the through groove 305 is used to allow rice to pass through and play a role in transmission.

[0022] The conveying mechanism 3 further includes a counterweight block 306 , the outer wall of which is fixedly connected to the outer wall of the second baffle plate 304 , and the counterweight block 306 is used to balance the weight of the second baffle plate 304 .

[0023] A fan 307 is fixedly connected to one side of the first baffle 301 , the interior of the fan 307 is communicated with the interior of the rotating rod 303 , and an air groove 308 and an air jet hole 309 are provided inside the second baffle 304 .

[0024] The air jet hole 309 is connected to the inside of the air slot 308, and the inside of the air slot 308 is connected to the inside of the fan 307 through the rotating rod 303. The fan 307 is used to play the role of blowing air; While ensuring that the rice is flattened and evenly transported, the rice will also pass through the through slot 305 in the second baffle 304. The rice not only passes through the bottom of the second baffle 304 but also passes through the through slot 305, thereby ensuring that the unevenly transported rice above the conveyor 2 can not only be kept evenly, but also the space between the bottom of the second baffle 304 and the through slot 305 can be used to ensure that a sufficient amount of rice can pass through the second baffle 304, thereby avoiding the problem of insufficient rice transportation caused by the need to flatten the rice and the short distance between the second baffle 304 and the conveyor 2; If the height between the second baffle 304 and the conveyor 2 is increased, part of the rice piled higher on the conveyor 2 will be flattened, but part of the rice that was originally piled lower and could not be touched by the second baffle 304 cannot be flattened by the bottom of the second baffle 304. Therefore, the second baffle 304 at a lower position is used to ensure that all the rice can be evenly flattened, and the through groove 305 is used to provide a sufficient amount of rice to pass through. After the rice passes through the through groove 305, it will naturally and evenly scatter on the conveyor 2, completing the work of evenly flattening a sufficient amount of rice. When the amount of rice transported on the conveyor 2 is too much and the working efficiency of rice transport and bran removal needs to be improved, then at this time, if the rice is still transported to the bran remover through the bottom of the second baffle plate 304 and the through groove 305, the amount of rice transported is insufficient. However, at this time, since there is a lot of rice on the conveyor 2, the thrust of the rice on the second baffle plate 304 is relatively large, so that the second baffle plate 304 drives the rotating rod 303 to be pushed and rotated on the bearing sleeve 302 and lifted up, so that the gap between the bottom of the second baffle plate 304 and the conveyor 2 will naturally become larger, so that the rice can be flattened under the transmission of this efficiency, and the amount of rice throughput is also increased. There is no need for manual operation by the staff, and the adjustment is automatically realized to ensure the stability of rice transportation and bran removal. When there is a lot of rice, it is piled high on the conveyor 2, and the second baffle 304 is automatically lifted, so that the gap between the second baffle 304 and the bottom conveyor 2 is increased, and the rice will not be unable to be moved. Therefore, while the lifting height of the second baffle 304 is automatically adjusted, it can also ensure that the rice is evenly moved without being affected. At the same time, the fan 307 is started to continuously inject air into the rotating rod 303. The air enters the air groove 308 in the second baffle 304 through the rotating rod 303, and then communicates with the air injection hole 309 inside the second baffle 304 through the air groove 308, and is ejected through the air injection hole 309 to continuously spray the rice below, ensuring that the rice does not get stuck or stuck when passing through. At the same time, the rice is simply dried to reduce moisture in the rice, so that the efficiency is more stable in the subsequent bran removal process. Example 3: Please refer to Figure 1-12 On the basis of the first and second embodiments, the present invention provides a technical solution: an auxiliary mechanism 4 is arranged at the bottom of the second baffle 304, the auxiliary mechanism 4 includes a roller 401, the outer wall of the roller 401 contacts the bottom of the second baffle 304, a connecting rod 403 is fixedly connected to one side of the roller 401, and the outer wall of the connecting rod 403 is fixedly connected to the soft hair 404 for stirring.

[0025] The outer wall of the roller 401 is rotatably connected to a rotating sleeve 402 , and the outer wall of the rotating sleeve 402 is fixedly connected to a telescopic plate 405 , and one end of the telescopic plate 405 is fixedly connected to the bottom of the second baffle 304 .

[0026] The inner wall of the telescopic plate 405 is provided with a built-in spring, which is used to reset the telescopic plate 405; During the transportation process of the conveyor 2, it will contact the roller 401 above, and the friction force of the contact drives the roller 401 to rotate synchronously. When the roller 401 rotates, it drives the connecting rod 403 to rotate. The connecting rod 403 rotates through the soft hair 404 on the outer wall to complete the stirring of the rice below. The rice passing under the second baffle 304 is rotated and moved by the connecting rod 403 and the soft hair 404, so that the rice is evenly passed under the connecting rod 403, ensuring that the rice is flattened during transportation. At the same time, as the soft hair 404 is moved to the left, the rice will not be clumped and blocked on the right side of the second baffle 304 due to the moisture therein. The stirring of the soft hair 404 can effectively break up the rice pile and fully spread the rice, so that the rice can pass through the bottom of the connecting rod 403 more evenly and efficiently. When the second baffle plate 304 is pushed and lifted by the rice, the bottom of the second baffle plate 304 will drive the telescopic plate 405 to be lifted, and the telescopic plate 405 will drive the connecting rod 403 to move together through the rotating sleeve 402, and the inner wall of the telescopic plate 405 is provided with a built-in spring, which will rebound to push the rotating sleeve 402 below outward, so that the rotating sleeve 402, the connecting rod 403 and the roller 401 can stably press the conveyor 2 below. Even if the second baffle plate 304 is lifted, the roller 401 can stably contact the surface of the conveyor 2, and be driven to make the connecting rod 403 and the soft hair 404 rotate together to complete the function of rotating and stirring the rice, ensuring that the rice can be moved by the soft hair 404 in various working conditions, ensuring its stable transportation work; Example 4: Please refer to Figure 1-15 On the basis of the first, second and third embodiments, the present invention provides a technical solution: the outer wall of the second baffle 304 is provided with a movable dispersion mechanism 5, the movable dispersion mechanism 5 comprises: a thin plate 501, the top of the thin plate 501 is fixedly connected to a top block 502, the bottom of the top block 502 is fixedly connected to a first elastic rope 503, the bottom end of the first elastic rope 503 is fixedly connected to a slider 504, the bottom of the slider 504 is fixedly connected to a third elastic rope 506, and the outer wall of the slider 504 is fixedly connected to a separation rod 505; When the second baffle 304 is in a vertical state, the rice is separated by the plurality of separation rods 505 while passing through the through slot 305, so as to prevent the rice grains from being too densely piled up, resulting in the moisture inside adhering to the clumps, poor ventilation, increased humidity, and thus causing the problem of mildew. When the amount of rice is large or the transmission speed is fast, the second baffle 304 is pushed to tilt. At this time, when it is necessary to ensure the faster transportation volume and transmission efficiency of the rice, the slider 504 on the thin plate 501 changes from a vertical state to an inclined state when the second baffle 304 is in an inclined state, pulling the first elastic rope 50 3 decreases, the elastic force of the first elastic rope 503 pulls the slider 504 back, so that the slider 504 slides and rises on the outer wall of the thin plate 501, and the elastic force of the third elastic rope 506 connected between each slider 504 also contracts, so that each slider 504 below is pulled up to a certain extent, and several sliders 504 are pulled back to the upper side of the second baffle 304, so that the through slot 305 is completely opened to ensure that when the rice needs to be transported quickly, the corresponding transportation effect is given, so that different methods can be adopted in different working states to improve the transportation efficiency of the rice in a targeted manner.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
