[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A rice dust removal device comprises a top cover plate and a fan unit, wherein the fan unit is movably arranged on the upper end surface of the top cover plate, the top cover plate comprises a plate frame and assembly blocks arranged on both sides of the edge position of the upper end surface of the plate frame, a matching block is clamped between two adjacent groups of assembly blocks, a cushion block is transversely arranged at one end of the outer side of the matching block, and an auxiliary mechanism is transversely arranged on the outer end surface of the cushion block;

[0008] The plate frame includes a frame body and a hollow cavity opened in the middle of the frame body, a load-bearing cross bar is opened transversely on the side end surface of the frame body, insertion grooves are opened on both sides of the upper end surface of the load-bearing cross bar, and positioning blocks are fixedly installed at both ends of the load-bearing cross bar.

The inner assembly block and the connecting block are arranged in the inner cavity of the auxiliary inner clamping groove. The inner assembly block connecting block and the connecting belt are not installed in the working state. The staff can penetrate through the inner cavity of the auxiliary inner clamping groove from top to bottom and pour rice into the inner cavity of the auxiliary inner clamping groove, so that the rice in the dust removal process can be mixed with the new rice and processed at the same time. Such operation can save time while ensuring the overall quality and taste of the rice.

[0010] Preferably, the top cover plate also includes a pressing mechanism installed at the edge positions on both sides of the bottom of the frame, the pressing mechanism includes a pressing horizontal bar and a hollow hole opened at the top position of the pressing horizontal bar, the upper and lower groups of the pressing horizontal bars are supported by auxiliary vertical bars on both sides, and an adjusting cylinder is vertically installed between the two groups of the pressing horizontal bars, and the overall device is placed from top to bottom just above the plastic square barrel for storing rice, so that the edge of the lower end surface of the frame can be just clamped on the top of the plastic square barrel, at this time, the outer end surface of the pressing mechanism is fitted into the inner wall of the plastic square barrel, when the bottom of the pressing horizontal bar below contacts the top of the stored rice, the adjusting cylinder and the auxiliary vertical bars can be telescopically adjusted according to the height of rice of different capacities in the plastic square barrel, thereby ensuring the stability of the equipment during use and reducing the situation where the upper surface of the rice shakes back and forth due to shaking of the equipment during dust removal, thereby preventing the rice from jumping out of the plastic square barrel.

[0011] Preferably, the adjusting cylinder comprises a first ring and a second ring sleeved on one end of the first ring, and two groups of the second rings arranged upper and lower are connected by a cylinder body, and the inner cavities of the first ring, the second ring and the cylinder body are all connected to the hollow hole, and the upper end surface of the downward pressing bar is in contact with the two sides of the edge of the lower end surface of the frame body, so that the plate frame and the downward pressing mechanism become a whole, and when a certain amount of rice is taken out of the plastic square barrel, the cylinder body releases the accumulated elastic potential energy, continuously presses the downward pressing bar at the bottom downward, and auxiliary vertical bars are used to fix the adjusting cylinder and the downward pressing bar to prevent the downward pressing bar from deflecting during the downward pressing process, and the downward pressing mechanism that continuously presses downward can keep the rice in a stable pressing position.

[0012] Preferably, the top cover plate also includes a dustproof mechanism inserted into the inner cavity of the frame from bottom to top, the dustproof mechanism includes a dustproof plate and a weighted box installed at the bottom of the dustproof plate, ventilation holes are arranged around the weighted box, and an upper insertion plate is installed on the top of the dustproof plate, and the outer end surface of the upper insertion plate is attached to the inner cavity wall of the frame. When there is no need to remove dust from the rice, the staff can press the dustproof plate and the upper insertion plate against the inner cavity of the hollow cavity from bottom to top, and at this time, the two groups of connecting blocks are connected by a connecting belt, and the upper end surface of the connecting belt can provide upward supporting force to the dustproof mechanism, so that the overall device forms a closed cover relative to the plastic square barrel, which can maintain a relatively sealed state in the plastic square barrel, thereby increasing the functional diversity of the overall device.

[0013] Preferably, the fanning unit includes two groups of fanning brackets and a connecting rod laterally connected between the two groups of fanning brackets, auxiliary brackets are laterally cross-arranged on both sides of the upper end surface of the connecting rod, and fan blades are laterally arranged on the side end surfaces of the connecting rod. The adaptive ability and elastic driving mechanism in the process of rice taking make the device have good controllability and real-time response ability. This intelligent operation is more conducive to optimizing the rice cleaning process and improving work efficiency.

[0014] An external driving motor is used to drive one end of the fan bracket to be adjusted so that the fan bracket and the cushion block can be swung up and down with the hinge as the fulcrum. During the overall swinging of the fan unit, the contact area between the overall device and the air is increased by the arranged fan blades, so that the wind force generated during the swinging process can pass downward through the inner cavity of the hollow cavity and enter the inner cavity of the plastic square barrel to remove dust from the rice in the plastic square barrel. In addition, the staff can shake the plastic square barrel with the help of external force, so as to cooperate with the overall device to remove dust from the rice in the barrel, and effectively remove dust and perform other treatments on the rice that has been in a static state for a long time.

[0015] With respect to the above embodiments, the following different embodiments are given to distinguish the effects:

The protruding horizontal bars of the swinging component can make the airflow more evenly distributed in the entire processing area, avoiding the uneven effect caused by the airflow concentrated in a certain part.

[0020] The rice dust removal process of the rice dust removal device comprises the following steps:

[0021] S1: The whole device is placed from top to bottom just above the plastic square barrel for storing rice, so that the edge of the lower end surface of the frame can be just snapped onto the top of the plastic square barrel, and the outer end surface of the pressing mechanism fits into the inner wall of the plastic square barrel, so that the device can always keep working normally under different amounts of rice storage conditions, and the rice placed in the plastic square barrel will never fall out of the whole device;

[0022] S2: An external driving motor is used to drive one end of the fan bracket to adjust, so that the fan bracket and the cushion block can swing up and down with the hinge bar as the fulcrum. During the overall swinging of the fan unit, the contact area between the overall device and the air is increased by the arranged fan blades, so that the wind force generated during the swinging process can pass downward through the inner cavity of the hollow cavity and enter the inner cavity of the plastic square barrel, and the rice in the plastic square barrel is dusted by wind. In addition, the staff can shake the plastic square barrel with the help of external force, so as to cooperate with the overall device to perform dust removal on the rice in the barrel, and effectively remove dust and other treatments are performed on the rice that has been in a static state for a long time;

[0023] S3: The multiple groups of protruding horizontal bars arranged horizontally at the bottom of the plate can slightly change the airflow of the fanning wind during the swinging process, so that the airflow can cover all parts of the rice more widely, and can stir up the tiny dust attached to the surface of the rice, thereby increasing the effect of wind dust removal and better cleaning the rice. The protruding horizontal bars of the swinging components can make the airflow more evenly distributed in the entire processing area, avoiding the uneven effect caused by the airflow concentrated in a certain part.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] Height self-adaptation: By adjusting the extension and retraction of the cylinder and auxiliary vertical bars, the overall device can be adjusted according to the height of the rice in the plastic bucket, maintaining stability and preventing the rice from jumping out of the plastic bucket due to shaking.

[0026] Intelligent elastic drive: The overall device responds to the rice taking process in real time through the elastic drive mechanism, keeps the rice in a stable position, and adjusts the pressure in real time to maintain good controllability.

[0027] Optimize the cleaning process: The device increases the contact surface with the air through swing adjustment and the addition of fans, which helps the wind dust removal effect, can effectively clean the rice, and improve the cleaning efficiency.

[0028] Adaptable to various environments: Whether it is the moisture absorption problem caused by excessive humidity, or the growth of pests such as borers in rice due to poor sealing, the overall device can effectively respond and deal with it.

[0029] Rice mixing process: The staff pours in new rice for mixing, which saves time and ensures the overall quality and taste of the rice.

[0030] Functional diversity: When dust removal is not required, the entire device can form a closed cover through the dustproof plate and the upper insert plate to maintain a relatively sealed state in the plastic square barrel.

[0031] Efficient cleaning: By swinging the protruding horizontal bars, the airflow of the wind dust removal can be changed, so that the airflow covers the rice more widely and cleans the rice better. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Embodiment 5, the fanning unit 2 includes two groups of fanning brackets 21 and a connecting rod 22 laterally connected between the two groups of fanning brackets 21, auxiliary brackets 23 are laterally cross-arranged on both sides of the upper end surface of the connecting rod 22, and fan blades 24 are laterally arranged on the side end surface of the connecting rod 22. The adaptive ability and elastic driving mechanism in the process of rice taking make the device have good controllability and real-time response ability. This intelligent operation is more conducive to optimizing the rice cleaning process and improving work efficiency.

[0049] Embodiment 6, by driving one end of the fan bracket 21 through an external driving motor to adjust, the fan bracket 21 and the cushion block 14 can be swung up and down with the hinge bar as the fulcrum. During the overall swinging of the fan unit 2, the contact area between the overall device and the air is increased by the arranged fan blades 24, so that the wind force generated during the swinging process can pass downward through the inner cavity of the hollow cavity 112 opened, and enter the inner cavity of the plastic square barrel downward, so as to remove dust from the rice in the plastic square barrel by wind, and the staff can shake the plastic square barrel with the help of external force, so as to cooperate with the overall device to remove dust from the rice in the barrel, and effectively remove dust and other treatments can be performed on the rice that has been in a static state for a long time.

[0050] Embodiment 7, with respect to the above embodiments, the following distinguishing embodiments are given to distinguish the effects:

[0051] If the storage environment is humid, the rice will absorb moisture. Through the effective treatment of the overall device, the static rice can be dried;

[0052] If the storage is not well sealed, borers or other pests will grow in the rice. By blowing the entire device, the borers hidden shallowly in the rice can be blown out, and the staff can drive out the borers.

[0053] Embodiment 8, the fan blade 24 includes a plate 241 and matching grooves 242 installed on both sides of the side end surface of the plate 241, and the lower end surface of the plate 241 is arranged with protruding horizontal bars 243. The multiple groups of protruding horizontal bars 243 arranged horizontally at the bottom of the plate 241 can slightly change the airflow of the fanned wind during the swinging process, so that the airflow can cover all parts of the rice more widely, and can stir up tiny dust attached to the surface of the rice, thereby increasing the effect of wind dust removal and better cleaning the rice. The swinging component protruding horizontal bars 243 can make the airflow more evenly distributed in the entire processing area, avoiding the uneven effect caused by the airflow concentrated in a certain part.

[0054] The lower end surface of the fan bracket 21 is attached to the upper end surface of the cushion block 14, one end of the fan bracket 21 is movably connected to the side end surface of the cushion block 14 through a hinge, and the other end of the fan bracket 21 is downwardly inserted into the inner cavity of the insertion groove 114, so that the top cover plate 1 and the fan unit 2 become a whole.

[0055] The rice dust removal process of the rice dust removal device comprises the following steps:

[0056] S1: The whole device is placed from top to bottom just above the plastic square barrel for storing rice, so that the lower end edge of the frame 111 can be just snapped onto the top of the plastic square barrel, and the outer end surface of the pressing mechanism 16 fits into the inner wall of the plastic square barrel, so that the device can always keep working normally under different amounts of rice storage conditions, and the rice placed in the plastic square barrel will never fall out of the whole device;

[0057] S2: An external driving motor is used to drive one end of the fan bracket 21 to adjust so that the fan bracket 21 and the cushion block 14 can swing up and down with the hinge bar as the fulcrum. During the overall swinging of the fan unit 2, the fan blades 24 are provided to increase the contact area between the overall device and the air, so that the wind force generated during the swinging process can pass downward through the inner cavity of the hollow cavity 112 and enter the inner cavity of the plastic square barrel, thereby performing wind-force dust removal on the rice in the plastic square barrel. In addition, the staff can shake the plastic square barrel with the help of external force, thereby cooperating with the overall device to perform dust removal on the rice in the barrel, and effectively perform dust removal and other treatment on the rice that has been in a static state for a long time;

[0058] S3: The multiple groups of protruding horizontal bars 243 arranged laterally at the bottom of the plate 241 can slightly change the airflow of the fanned wind during the swinging process, so that the airflow can cover all parts of the rice more widely, and can stir up the tiny dust attached to the surface of the rice, thereby increasing the effect of wind dust removal and better cleaning the rice. The swinging component protruding horizontal bars 243 can make the airflow more evenly distributed in the entire processing area, avoiding the uneven effect caused by the airflow being concentrated in a certain part.

[0059] In summary, the whole device is placed from top to bottom just above the plastic square barrel for storing rice, so that the edge of the lower end surface of the frame 111 can be just snapped onto the top of the plastic square barrel. At this time, the outer end surface of the pressing mechanism 16 is fitted into the inner wall of the plastic square barrel. When the bottom of the pressing horizontal bar 161 below contacts the top of the stored rice, the adjusting cylinder 164 and the auxiliary vertical bar 163 can be telescopically adjusted according to the height of rice of different capacities in the plastic square barrel, thereby ensuring the stability of the device during use and reducing the situation in which the upper surface of the rice shakes back and forth due to shaking of the device during dust removal, thereby preventing the rice from jumping out of the plastic square barrel.

[0060] When the capacity of rice in the plastic square barrel is large, the first ring 1641 and the second ring 1642 will translate upward under the drive of the bottom pressing horizontal bar 161, so that the cylinder 1643 is squeezed toward its middle position. After squeezing, the cylinder 1643 will shrink inward to a state where it is wide at the upper and lower ends and narrow in the middle, so that the pressing mechanism 16 itself can accumulate elastic potential energy. When a certain amount of rice is taken out of the plastic square barrel, the cylinder 1643 releases the accumulated elastic potential energy, continuously presses the bottom pressing horizontal bar 161 downward, and assists in fixing the adjustment cylinder 164 and the pressing horizontal bar 161 through the auxiliary vertical bar 163 to prevent the pressing horizontal bar 161 from deflecting during the pressing process. The pressing mechanism 16 that continuously presses downward can keep the rice in a stable pressing position.

[0061] The adaptive ability and flexible driving mechanism during the rice retrieval process give the device good controllability and real-time response capabilities. This intelligent operation is more conducive to optimizing the rice cleaning process and improving work efficiency.

[0062] An external driving motor is used to drive one end of the fan bracket 21 to be adjusted, so that the fan bracket 21 and the cushion block 14 can be swung up and down with the hinge as the fulcrum. During the overall swinging of the fan unit 2, the contact area between the overall device and the air is increased by the arranged fan blades 24, so that the wind force generated during the swinging process can pass downward through the inner cavity of the hollow cavity 112 opened, and enter the inner cavity of the plastic square barrel downward, so as to remove dust from the rice in the plastic square barrel by wind, and the staff can shake the plastic square barrel with the help of external force, so as to cooperate with the overall device to remove dust from the rice in the barrel, and effectively remove dust and other treatments can be performed on the rice that has been in a static state for a long time.

[0063] If the storage environment is humid, the rice will absorb moisture. Through the effective treatment of the overall device, the stationary rice can be dried.

[0064] If the storage is not well sealed, borers or other pests will grow in the rice. By blowing the entire device, the borers hidden shallowly in the rice can be blown out, and the staff can drive out the borers.

[0065] By means of the inner assembly block 152 and the connecting block 153 arranged in the inner cavity of the auxiliary inner clamping groove 151, the inner assembly block 152, the connecting block 153 and the connecting belt 154 are not installed in the working state. The staff can penetrate through the inner cavity of the auxiliary inner clamping groove 151 from top to bottom and pour rice into the inner cavity of the auxiliary inner clamping groove 151, so that the rice in the dust removal process can be mixed with the new rice and processed at the same time. Such operation can save time while ensuring the overall quality and taste of the rice.

[0066] When there is no need to remove dust from the rice, the staff can press the dustproof plate 171 and the upper insertion plate 174 from bottom to top against the inner cavity of the hollow cavity 112, and at this time, the two sets of connecting blocks 153 are connected by the connecting belt 154. The upper end surface of the connecting belt 154 can provide upward supporting force for the dustproof mechanism 17, so that the overall device forms a closed cover relative to the plastic square barrel, which can maintain a relatively sealed state in the plastic square barrel, and increase the functional diversity of the overall device.

[0067] The multiple groups of protruding horizontal bars 243 arranged laterally at the bottom of the plate 241 can slightly change the airflow of the fanned wind during the swinging process, allowing the airflow to cover various parts of the rice more widely, stirring up tiny dust attached to the surface of the rice, increasing the effect of wind dust removal, and better cleaning the rice. The swinging component protruding horizontal bars 243 can make the airflow more evenly distributed in the entire processing area, avoiding the uneven effect caused by the airflow concentrated in a certain part.

[0068] The above is the entire working principle of the present invention.

[0069] In the present invention, the installation method, connection method or setting method of all the above components are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology.

8. The rice dust removal process of the rice dust removal device according to any one of claims 1 to 7, characterized in that: The following steps are involved: S1: The entire device is placed from top to bottom directly above a plastic square barrel for storing rice, so that the edge of the lower end surface of the frame (111) can be just engaged with the upper part of the plastic square barrel. At this time, the outer end surface of the pressing mechanism (16) fits into the inner wall of the plastic square barrel, so that the device can always maintain normal operation under different amounts of rice storage conditions, and the rice placed in the plastic square barrel will never fall out of the entire device; S2: An external drive motor is used to drive one end of the fan bracket (21) to adjust so that the fan bracket (21) and the cushion block (14) can swing up and down with the hinge bar as the fulcrum. During the swinging of the fan unit (2), the contact area between the entire device and the air is increased by the fan blades (24). Thus, the wind force generated during the swinging process can pass downward through the inner cavity of the hollow cavity (112) and enter the inner cavity of the plastic square barrel, thereby removing dust from the rice in the plastic square barrel. The staff can shake the plastic square barrel with the help of an external force, thereby cooperating with the entire device to remove dust from the rice in the barrel, thereby effectively removing dust and other treatments for the rice that has been in a static state for a long time. S3: The plurality of groups of protruding horizontal bars (243) disposed transversely at the bottom of the plate (241) can slightly change the airflow of the fanned wind during the swinging process, so that the airflow can more widely cover various parts of the rice, and can stir up tiny dust attached to the surface of the rice, thereby increasing the effect of wind dust removal and better cleaning the rice. The swinging component protruding horizontal bars (243) can make the airflow more evenly distributed in the entire processing area, avoiding the situation where the airflow is concentrated in a certain part and causes uneven effects.
