Benefits of technology

[0016] In operation, workers first pour rice into the removal box through the feeding inlet. A blower assembly then blows air into the waste inlet. Because the husks and stalks are relatively light, they are drawn into the waste inlet by the blower during their fall, separating them from the rice and achieving initial impurity removal. Once all the rice has landed on the removal box, a vibrating cylinder, via a telescopic rod, drives the grain discharge plate in a rapid, circular reciprocating motion above the lifting plate assembly. During this motion, the rice, under the influence of gravity and inertia, continuously bounces back towards the junction of the removal box, similar to a farmer using a winnowing basket to sift grain. During the movement of the rice grains, clumps of rice continuously impact the impurity removal box until they break apart. Simultaneously, the rice grains, constantly being thrown upwards, are continuously blown by the air blowing component, carrying the broken husks and stalks towards the waste inlet, reducing the amount of impurities in the rice. The machine effectively breaks down clumps of rice and removes impurities during operation, improving the crushing effect and screening efficiency. After processing, the telescopic rod of the vibrating cylinder retracts until the lifting plate assembly acts on the discharge plate. The retraction of the lifting plate assembly, in conjunction with the telescopic rod, causes the discharge plate, supported by the sliding assembly, to slide away from the impurity removal box. After the discharge plate slides, the discharge port is open, and the impurity removal box is tilted towards the vibrating cylinder. Under gravity, the rice grains in the impurity removal box move towards the bottom of the impurity removal chamber. Finally, the grains are discharged through the discharge port, completing the entire processing. It is simple to operate and convenient to use, achieving the effect of improving the crushing effect of clumped rice and increasing screening efficiency.

Description

Technical Field

[0001] This utility model relates to the technical field of rice purification equipment, specifically to a rice recycling device with impurity removal function. Background Technology

[0002] Currently, after purchasing rice, due to the presence of numerous impurities such as broken husks and stalks, impurity removal equipment is typically used to process the rice. Existing impurity removal equipment usually includes a machine body with a feeding port at the top and a discharge port at the bottom. A removal chamber is located within the machine body, connected to a screening plate with multiple screening holes. A vibration motor is fixedly connected to the outside of the machine body and is linked to the screening plate. During operation, workers feed the rice to be screened into the machine through the feeding port. The rice falls onto the screening plate, and the vibration motor causes the plate to vibrate. The vibrating rice on the screening plate then falls through the screening holes into the discharge port below, where it is finally discharged.

[0003] The aforementioned prior art has the following drawbacks:

[0004] During use, the rice grains placed on the screening plate may clump together. Since the vibration range of the screening plate is mainly horizontal, it is difficult to quickly break up the clumps of rice grains. As a result, the clumps of rice grains remain on the screening plate, hindering the screening process of the scattered rice grains, reducing the practicality of the screening equipment, and slowing down the efficiency of the impurity removal work. Utility Model Content

[0005] The purpose of this utility model is to provide a rice recycling device with impurity removal function, so as to improve the crushing effect of clumped rice and improve the screening efficiency, thereby solving the problems mentioned in the background art.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0007] A rice recycling device with impurity removal function includes a body with a feeding port at the top and a discharge port at the bottom. An impurity removal chamber is located within the body, containing a rectangular impurity removal box. The top of the box is open, with its sidewalls abutting against the inner wall of the chamber, and its end face not touching the inner wall. One end of the box is hinged to the inner wall of the chamber, and the other end is connected to a vibrating cylinder with a telescopic rod. The vibrating cylinder is rotatably connected to the chamber via a fixed plate. The end of the telescopic rod is hinged to the side of the box away from the impurity removal chamber. At the feeding port, the end of the impurity removal box near the vibrating cylinder is open to form a grain outlet. A grain outlet plate is sealed in the grain outlet by a sliding component. A lifting plate component is set between the grain outlet plate and the impurity removal chamber. The lifting plate component allows the grain outlet plate to open. The vibrating cylinder drives the impurity removal box to perform an arc-shaped reciprocating lifting and lowering motion above the lifting plate component. A waste outlet is opened on the impurity removal chamber. The waste outlet is located above the impurity removal box. A blowing component is set at the position opposite the waste outlet in the impurity removal chamber. The blowing component provides airflow in the direction of the waste outlet. The airflow flows over the impurity removal box.

[0008] As a preferred embodiment of the present invention, the sliding component includes an arc-shaped sliding groove, the shape of which matches the movement trajectory of the impurity removal plate near the end of the vibrating cylinder. A slider is slidably connected in the sliding groove, and the slider extends out of the sliding groove and is fixedly connected to the grain discharge plate.

[0009] As a preferred embodiment of the present invention, the lifting plate assembly includes a lifting plate, which is fixedly connected to the top of the grain discharge plate. The lifting plate is located outside the impurity removal box, and an abutment plate is provided below the lifting plate. The abutment plate is fixedly connected to the inner wall of the impurity removal chamber. When the lifting plate abuts against the abutment plate, the lifting plate no longer moves downward with the impurity removal box.

[0010] In a preferred embodiment of this invention, a first magnetic plate is embedded in the impurity removal box facing the grain discharge plate, and a second magnetic plate is embedded in the grain discharge plate. When the grain discharge plate is sealed at the grain discharge port, the first magnetic plate and the second magnetic plate abut against each other and attract each other. After the first magnetic plate and the second magnetic plate attract each other, the relative position of the grain discharge plate and the impurity removal box remains fixed.

[0011] As a preferred embodiment of this utility model, the blowing assembly includes a blower fixed to the outside of the machine body, the blower is connected to a ventilation pipe, the ventilation pipe extends into the inside of the machine body and is connected to a wind box, the wind box is fixedly connected to the inner wall of the impurity removal chamber, the wind box has an air cavity, and a blower is fixedly connected to the side of the wind box facing the waste port, the blower is positioned facing the waste port, and multiple blowers are provided, each blower is connected to the air cavity.

[0012] As a preferred embodiment of this invention, the waste outlet is sealed with a collection bag, and the collection bag is a woven bag.

[0013] In a preferred embodiment of this utility model, the discharge port is located near the vibrating cylinder, and a guide block is fixedly connected to the bottom wall of the impurity removal chamber. The guide block has a right-angled triangular cross-section, the side of the guide block abuts against the inner wall of the impurity removal chamber, the top surface of the guide block is inclined, the guide block is lower in height near the discharge port, and higher in height away from the discharge port, and the guide block extends to the position near the discharge port.

[0014] Beneficial effects

[0015] The beneficial effects of this utility model are:

[0016] In operation, workers first pour rice into the removal box through the feeding inlet. A blower assembly then blows air into the waste inlet. Because the husks and stalks are relatively light, they are drawn into the waste inlet by the blower during their fall, separating them from the rice and achieving initial impurity removal. Once all the rice has landed on the removal box, a vibrating cylinder, via a telescopic rod, drives the grain discharge plate in a rapid, circular reciprocating motion above the lifting plate assembly. During this motion, the rice, under the influence of gravity and inertia, continuously bounces back towards the junction of the removal box, similar to a farmer using a winnowing basket to sift grain. During the movement of the rice grains, clumps of rice continuously impact the impurity removal box until they break apart. Simultaneously, the rice grains, constantly being thrown upwards, are continuously blown by the air blowing component, carrying the broken husks and stalks towards the waste inlet, reducing the amount of impurities in the rice. The machine effectively breaks down clumps of rice and removes impurities during operation, improving the crushing effect and screening efficiency. After processing, the telescopic rod of the vibrating cylinder retracts until the lifting plate assembly acts on the discharge plate. The retraction of the lifting plate assembly, in conjunction with the telescopic rod, causes the discharge plate, supported by the sliding assembly, to slide away from the impurity removal box. After the discharge plate slides, the discharge port is open, and the impurity removal box is tilted towards the vibrating cylinder. Under gravity, the rice grains in the impurity removal box move towards the bottom of the impurity removal chamber. Finally, the grains are discharged through the discharge port, completing the entire processing. It is simple to operate and convenient to use, achieving the effect of improving the crushing effect of clumped rice and increasing screening efficiency. Attached Figure Description

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] See Figure 1-3As shown, a rice recycling device with impurity removal function includes a body 1, in which an impurity removal chamber 13 is provided. A rectangular impurity removal box 2 is disposed within the impurity removal chamber 13, parallel to the bottom wall of the chamber 13. The top surface of the impurity removal box 2 is open. The side wall of the impurity removal box 2 abuts against the inner wall of the chamber 13. This abutment prevents rice grains from falling from the side of the box 2 to the bottom of the chamber 13. The end face of the impurity removal box 2 is not in contact with the inner wall of the chamber 13. The gap between the end face of the box 2 and the inner wall of the chamber 13 facilitates the movement and discharge of the box 2, improving its stability and ease of use. One end of the impurity removal box 2 is hinged to the inner wall of the impurity removal chamber 13, and the other end of the impurity removal box 2 is connected to a vibrating cylinder 3 with a telescopic rod 31. The machine body 1 is provided with a feeding port 11, which is located above the junction of the impurity removal box 2 and the impurity removal chamber 13. The machine body 1 is provided with a discharge port 12, which is located near the vibrating cylinder 3. A guide block 8 is fixedly connected to the bottom wall of the impurity removal chamber 13. The vertical section of the guide block 8 is set in a right-angled triangle. The side of the guide block 8 abuts against the inner wall of the impurity removal chamber 13. The top surface of the guide block 8 is set in an inclined shape. The height of the guide block 8 is lower when it is near the middle discharge port 12, and higher when it is away from the discharge port 12. The guide block 8 extends to the position near the discharge port 12. The guide block 8 can guide the rice towards the discharge port 12, improve the discharge speed of the rice, and reduce the amount of rice remaining in the impurity removal chamber 13.

[0027] See Figure 1-4 As shown, the vibrating cylinder 3 is rotatably connected to the impurity removal chamber 13 via a fixed plate, which is fixedly connected to the impurity removal chamber 13. The end of the telescopic rod 31 is hinged to the impurity removal box 2 at a position away from the feeding port 11. The end of the impurity removal box 2 near the vibrating cylinder 3 is open, forming a grain outlet 21. A square grain outlet plate 4 is sealed in the grain outlet 21 by a sliding component 6. The sliding component 6 is located on the side of the grain outlet plate 4. A first magnetic plate 22 is embedded in the impurity removal box 2 facing the grain outlet plate 4, and a second magnetic plate 23 is embedded in the grain outlet plate 4. When the grain outlet plate 4 is sealed at the grain outlet 21, the first magnetic plate 22 and the second magnetic plate 23 abut against each other and attract each other. After the first magnetic plate 22 and the second magnetic plate 23 attract each other, the relative position of the grain outlet plate 4 and the impurity removal box 2 remains fixed, thereby preventing the grain outlet plate 4 from sliding due to inertia and improving the stability of the grain outlet plate 4 when sealing the grain outlet 21.

[0028] See Figure 1 and Figure 4 As shown, the sliding component 6 includes an arc-shaped sliding groove 61. The shape of the sliding groove 61 matches the movement trajectory of the impurity removal plate near the end of the vibrating cylinder 3. A slider 62 is slidably connected in the sliding groove 61. The slider 62 extends out of the sliding groove 61 and is fixedly connected to the grain discharge plate 4.

[0029] See Figure 1-4 As shown, a lifting plate assembly 5 is provided between the grain discharge plate 4 and the impurity removal chamber 13. The vibrating cylinder 3 drives the impurity removal box 2 to perform a circular reciprocating lifting and lowering motion above the lifting plate assembly 5. The lifting plate assembly 5 includes a square lifting plate 51, which is perpendicular to the grain discharge plate 4 and fixedly connected to the top of the grain discharge plate 4. The lifting plate 51 is located outside the impurity removal box 2. A square abutment plate 52 is provided below the lifting plate 51 and is fixedly connected to the inner wall of the impurity removal chamber 13. When the lifting plate 51 abuts against the abutment plate 52, the lifting plate 51 no longer moves downward with the impurity removal box 2, and then continues to move downward through the impurity removal box 2. The grain discharge plate 4 opens the grain discharge port 21 with the support of the sliding assembly 6, making it easy to completely pour out the rice in the impurity removal box 2. The operation is simple and convenient.

[0030] See Figure 1-4 As shown, a square waste port 7 is provided on the side wall between the waste removal box 2 and the feeding port 11 in the impurity removal chamber 13. The waste port 7 is connected to the outside. A collection bag 72 made of woven burlap is sealed at the end of the waste port 7 away from the impurity removal chamber 13. A blowing assembly 71 is provided in the impurity removal chamber 13 at the position opposite to the waste port 7. The blowing assembly 71 includes a blower 711 fixed to the outside of the machine body 1. The blower 711 is connected to a ventilation pipe. The ventilation pipe extends into the inside of the machine body 1 and is connected to a bellows box 712. The bellows box 712 is fixedly connected to the inner wall of the impurity removal chamber 13. The bellows 712 has an air chamber 713. A cylindrical blower 714 is fixedly connected to the side of the bellows 712 facing the waste port 7. The blower 714 is positioned facing the waste port 7. There are multiple blowers 714, and each blower 714 is connected to the air chamber 713. The airflow generated by the blower 711 enters the bellows 712 through the ventilation pipe, and then is sent out through the multiple blowers 714 connected to the air chamber 713. The multiple blowers 714 can make the air delivery area of ​​the bellows 712 larger, thereby improving the impurity removal effect on rice.

[0031] One specific application of this embodiment is:

[0032] Before the impurity removal feeding, the vibrating cylinder 3 raises the telescopic rod 31, and the height of the end of the impurity removal box 2 near the vibrating cylinder 3 is higher than the height of the hinge position of the impurity removal box 2. The blower 711 provides airflow towards the waste port 7 to the impurity removal chamber 13 through the ventilation pipe.

[0033] Workers feed rice into the impurity removal box 2 through the feeding port 11. Before falling into the impurity removal box 2, the rice passes through the working area of ​​the air blowing component 71, and the broken husks and stalks in the rice are blown into the waste port 7. After feeding is completed, the vibrating cylinder 3 first retracts the telescopic rod 31. The telescopic rod 31 drives the end of the impurity removal box 2 to descend towards the discharge port 12. Under the action of gravity, the grains in the impurity removal box 2 gradually roll towards the end of the impurity removal box 2 that is close to the vibrating cylinder 3. When the rice is about to roll to the end of the impurity removal box 2 that is close to the vibrating cylinder 3, the end of the impurity removal box 2 remains above the abutment plate 52. Then, the vibrating cylinder 3 quickly extends the telescopic rod 31, so that the end of the impurity removal box 2 returns to the initial tilted state through an arc-shaped rising trajectory. Under the action of gravity and inertia, the rice is thrown back towards the hinged end of the impurity removal box 2. During the process of the rice being thrown up, the rice passes through the working area of ​​the blowing component 71 again. When the rice falls into the impurity removal box 2, the clumps of rice are impacted and dispersed. Then, the vibrating cylinder 3 drives the impurity removal box 2 to repeat this operation, which disperses all the clumps of rice grains. At the same time, the broken husks and stalks in the rice grains are blown into the waste inlet 7, completing the work of breaking up and removing impurities from the rice grains. The broken husks and stalks collected in the waste inlet 7 are finally put into the collection bag 72 for unified storage.

[0034] When workers need to remove the cleaned rice, the vibrating cylinder 3 continuously retracts the telescopic rod 31. The end of the cleaned rice box 2 descends synchronously with the retraction of the telescopic rod 31. Under the action of gravity, the rice in the cleaned rice box 2 moves towards the descending end of the cleaned rice box 2. After the lifting plate 51 abuts against the abutting plate 52, the telescopic rod 31 continues to retract, and the cleaned rice box 2 continues to descend, but the descent of the lifting plate 51 stops. The sliding block slides upward in the sliding groove 61, and the first magnetic plate 22 and the second magnetic plate 23 separate from each other. The bottom surface of the discharge plate separates from the cleaned rice box 2, and the grain outlet 21 opens, pouring the rice under the cleaned rice box 2. The falling rice first contacts the guide block 8, and then the rice rolls along the guide block 8 to the discharge outlet 12 for discharge. In summary, through the above steps, the effect of breaking up clumps of rice is improved, and the screening efficiency is increased.

[0035] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
