[0048] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0049] Please refer to Figure 1 and Figure 2The broad bean screening device for bean paste production provided in the embodiments of the present invention can solve the above problems, which will be described in detail below.

[0050] The broad bean screening device for producing broad bean paste comprises a base 110, a feeding box 120, a first screen 130 and an anti-piling mechanism 140;

[0051] Among them, the feeding box 120 is connected to the base 110 and is provided with a discharge port 121. The first screen 130 is connected to the base 110 and is used to receive the material output from the discharge port 121. The anti-stacking mechanism 140 includes a connected driving member 141 and a barrier member 142. The driving member 141 is connected to the feeding box 120, and the barrier member 142 is movably arranged at the discharge port 121. The driving member 141 is used to drive the barrier member 142 to move along the width direction of the discharge port 121 to block part of the material.

[0052] During operation, the feeding box 120 is used to feed materials toward the first screen 130 through the discharge port 121. The driving member 141 can drive the barrier member 142 to move, so that the barrier member 142 can successively block parts of the materials at different positions passing through the discharge port 121, thereby preventing all materials from being quickly fed onto the first screen 130, reducing the probability of accumulation of materials when they just enter the first screen 130, preventing a decrease in screening efficiency, and avoiding blockage.

[0053] In this embodiment, the feeding box 120 is used to hold a certain amount of material, and the discharge port 121 is located at the bottom of the feeding box 120. The material can slide out through the discharge port 121 under the action of its own gravity. In addition, in order to increase the discharge rate, the inner bottom wall of the discharge port 121 can be inclined, extending from the inside to the outside toward the lower point.

[0054] It is worth noting that the device also includes a second screen 132, a first material box 135, a second material box 136, and a third material box 137. The first material box 135 is connected to the base 110 and located below the first screen 130, and is used to receive material that leaks out of the first screen 130. The second screen 132 is located on the side of the first screen 130 away from the discharge port 121. Material that does not pass through the first screen 130 will enter the second screen 132. The mesh of the second screen 132 is larger than the mesh of the first screen 130. The second material box 136 is connected to the base 110 and located below the second screen 132, and is used to receive material that leaks out of the second screen 132. The third material box 137 is located on the side of the second material box 136 away from the first material box 135, which allows the second screen 132 to be tilted, so that material that does not pass through the second screen 132 can smoothly enter the third material box 137 under the action of gravity.

[0055] In this embodiment, the number of the first screen 130, the second screen 132, the first material box 135, and the second material box 136 is one; in other embodiments of the present invention, the number of the first screen 130, the second screen 132, the first material box 135, and the second material box 136 can be multiple, and the specific number is not limited. In general, the farther the distance between the different screens and the discharge port 121, the larger the size of the mesh openings. In addition, it is necessary to make the length of the first screen 130 appropriate, on the one hand to facilitate the material to be fully screened on the first screen 130, and on the other hand to facilitate the material to move smoothly to the second screen 132 under its own inertia.

[0056] In this embodiment, the barrier 142 is a rectangular plate-like structure, and its two side walls are flat; of course, in other embodiments of the present invention, the barrier 142 may also be other shapes, and the two side walls of the barrier 142 may be curved surfaces or wavy surfaces. There is no limitation on the specific shape and side wall shape of the barrier 142.

[0057] Please refer to Figure 2 In order to avoid serious blockage of the material blocked by the barrier 142, the barrier 142 can be provided with a guide hole 1421, so that in addition to having the function of blocking the material, the barrier 142 can also facilitate part of the blocked material to pass through the guide hole 1421 and enter the first screen 130.

[0058] Specifically, the size of the guide hole 1421 can be adapted to the size of the mesh on the first screen 130 so that the material passing through the guide hole 1421 can leak out of the first screen 130. Of course, the size of the guide hole 1421 can also be larger or smaller than the size of the mesh on the first screen 130.

[0059] In this embodiment, the guide holes 1421 are elongated, and the direction in which the guide holes 1421 extend is consistent with the height direction of the discharge port 121. By limiting the shape of the guide holes 1421 to an elongated shape, the material flowing out of the guide holes 1421 is at a sufficient height from the first screen 130, so that the material can jump when it falls on the first screen 130, which helps to cause local vibration of the first screen 130, thereby promoting the flow of the material on the first screen 130. In addition, a plurality of guide holes 1421 can be provided, and the plurality of guide holes 1421 can be arranged in sequence along the width direction of the discharge port 121.

[0060] It should be noted that when there are multiple guide holes 1421 , two adjacent guide holes 1421 may be spaced apart from each other, or may be connected to each other.

[0061] Of course, in other embodiments of the present invention, the long extension direction of the long strip-shaped guide hole 1421 can be consistent with the width direction of the discharge port 121, or multiple long strip-shaped guide holes 1421 can be arranged in sequence along the height direction of the discharge port 121, or the guide holes 1421 can be circular, rectangular, fan-shaped or other shapes. There is no limitation on the specific shape and arrangement of the guide holes 1421.

[0062] Please refer to Figure 2 In order to achieve power transmission between the driving member 141 and the blocking member 142 , the anti-stacking mechanism 140 may further include a first transmission member 143 .

[0063] Specifically, the first transmission member 143 includes a transmission rod 1431, a transmission block 1432 and a transmission plate 1433. The end of the transmission rod 1431 is connected to the driving member 141. The extension direction of the transmission rod 1431 is consistent with the width direction of the discharge port 121. The transmission block 1432 is spirally engaged with the transmission rod 1431, and the transmission plate 1433 is connected between the transmission block 1432 and the barrier member 142.

[0064] During operation, the driving member 141 is used to provide a rotational power source to drive the transmission rod 1431 to rotate, and then use the spiral fit to make the transmission block 1432 move along the axial direction of the transmission rod 1431, and drive the blocking block along the axial direction of the transmission rod 1431 (that is, the width direction of the discharge port 121) through the transmission plate 1433, so as to achieve blocking of different positions in the width direction of the discharge port 121.

[0065] In this embodiment, the transmission rod 1431 is a screw, and the transmission block 1432 is a nut. The driving member 141 can be a rotary electric cylinder, a rotary air cylinder, or a rotary hydraulic cylinder. The driving member 141 can also be a rotary handle that rotates by manual force. The specific power form of the driving member 141 is not limited.

[0066] Please refer to Figure 3 In order to avoid serious blockage of the materials blocked by the barrier 142 and promote the dispersion of the materials near the discharge port 121, the anti-stacking mechanism 140 may further include a flipping member 144, which is connected to the driving member 141 and is rotatably arranged on the inner side of the discharge port 121.

[0067] It should be noted that the rotation center axis of the flipping member 144 can be parallel to the width direction of the discharge port 121, or parallel to the height direction of the discharge port 121, or can be set at an angle to the width direction and the height direction of the discharge port 121 at the same time, thereby realizing flipping operations in different directions and dimensions.

[0068] In this embodiment, the flipping member 144 includes a flipping shaft 1441 and a flipping plate 1442. The end of the flipping shaft 1441 is connected to the driving member 141. The extension direction of the flipping shaft 1441 is consistent with the width direction of the discharge port 121. The flipping plate 1442 is connected to the peripheral wall of the flipping shaft 1441 and rotates along the circumferential direction of the flipping shaft 1441.

[0069] The number of the flip plates 1442 may be one or more, and there is no limitation on the specific number of the flip plates 1442 .

[0070] Please refer to Figure 2 and Figure 3 In order to conveniently drive the flip shaft 1441 to rotate, the anti-stacking mechanism 140 may further include a second transmission member 145; wherein the second transmission member 145 includes a transmission main wheel 1451, a transmission auxiliary wheel 1452 and a transmission belt 1453. The transmission main wheel 1451 is coaxially connected to the driving member 141, the transmission auxiliary wheel 1452 is coaxially connected to the flip shaft 1441, and the transmission belt 1453 is simultaneously sleeved on the transmission main wheel 1451 and the transmission auxiliary wheel 1452. The transmission main wheel 1451, the transmission auxiliary wheel 1452 and the transmission belt 1453 can together form a synchronous belt structure, and the size difference between the transmission main wheel 1451 and the transmission auxiliary wheel 1452 can be used to realize differential transmission.

[0071] In this embodiment, a transmission rod 1431 may be connected between the transmission main wheel 1451 and the driving member 141 , that is, the transmission main wheel 1451 and the driving member 141 are coaxially connected to both ends of the transmission rod 1431 .

[0072] It is worth noting that the second transmission member 145 can also be a rotating handle, that is, the rotating handle is driven to rotate by manual force, thereby causing the flip shaft 1441 to rotate.

[0073] Furthermore, in order to simplify the overall structure, the two sides of the flip plate 1442 can be directly connected to the transmission rod 1431, and the middle position of the flip plate 1442 can be hollowed out to avoid the transmission block 1432. The flip plate 1442 can be a flexible sheet, and the transmission rod 1431 can drive the flip plate 1442 to rotate synchronously while rotating.

[0074] Please refer to Figure 1 、 Figure 2 and Figure 4 In order to increase the flow rate of the material on the first screen 130 and improve the screening efficiency, the broad bean screening device for bean paste production can further include a vibration mechanism 150. The vibration mechanism 150 can be one or more vibration motors installed on the lower side of the first screen 130, thereby driving the first screen 130 to vibrate.

[0075] In this embodiment, the vibration mechanism 150 can include a matching extension plate 151 and a vibration inclined plate 152. The extension plate 151 is connected to the barrier 142 and moves synchronously with the barrier 142. One end of the vibration inclined plate 152 is rotatably connected to the outer wall of the discharge port 121. The top wall of the other end of the vibration inclined plate 152 cooperates with the extension plate 151, so that the bottom wall of the vibration inclined plate 152 is against or away from the first screen 130, thereby driving the first screen 130 to vibrate.

[0076] In addition, there are two extension plates 151 , which are respectively connected to both sides of the barrier 142 ; there are multiple vibration inclined plates 152 , which are arranged in sequence along the width direction of the discharge port 121 .

[0077] When the barrier 142 moves along the width direction of the discharge port 121, it can drive the extension plates 151 on both sides to move synchronously, so that the extension plates 151 cooperate with the vibration inclined plates 152 at different positions in sequence, thereby driving the local position of the first screen 130 to vibrate.

[0078] Specifically, the bottom wall of the extension plate 151 is formed with a first arc block 1511 , and the top wall of the vibration inclined plate 152 away from the discharge port 121 is formed with a second arc block 1521 , and the first arc block 1511 cooperates with the second arc block 1521 .

[0079] It is worth noting that in order to facilitate the reciprocating motion of the vibration inclined plate 152 in conjunction with the extension plate 151, the vibration inclined plate 152 can be made into a flexible plate. When the vibration inclined plate 152 contacts the first screen 130, it can be reset by its own potential energy. Of course, the vibration mechanism 150 can also include an elastic member 153, which is connected between the outer wall of the discharge port 121 and the vibration inclined plate 152. The elastic member 153 can be a torsion spring or a spring. When it is a torsion spring, the middle part of the torsion spring is mounted on the rotating shaft at the rotational connection position between the vibration inclined plate 152 and the outer wall of the discharge port 121. When it is a spring, one end of the spring can be connected to the outer wall of the discharge port 121, and the other end can be connected to the vibration inclined plate 152 at a position away from the second arc block 1521.

[0080] Furthermore, in order to improve the convenience of installation, a support ear may be provided on the outer wall of the discharge port 121 , and a rotational connection with one end of the vibration inclined plate 152 may be achieved through the support ear.

[0081] Please refer to Figure 1 、 Figure 5 and Figure 6In order to improve the distribution effect of the material on the first screen 130 and prevent individual materials from being squeezed onto the second screen 132 without contacting the first screen 130 when passing through the first screen 130, the broad bean screening device for bean paste production may also include a distribution mechanism 160.

[0082] Specifically, the spreading mechanism 160 includes a connected follower 161 and a spreading member 162. The follower 161 is connected to the barrier 142 and moves synchronously with the barrier 142. The spreading member 162 is connected to the follower 161 and extends in a direction consistent with the direction of the discharge port 121. The spreading member 162 contacts the top surface of the first screen 130. In other words, when the barrier 142 moves, the follower 161 can drive the spreading member 162 to move, so that the spreading operation is achieved through the contact between the spreading member 162 and the material.

[0083] In this embodiment, the flattening member 162 is cylindrical, and the cylindrical extension direction is consistent with the direction of the discharge port 121; of course, in other embodiments of the present invention, the flattening member 162 can also be in the shape of a bent connecting rod, and its specific shape is not limited.

[0084] Furthermore, in order to prevent the material from sliding out from both sides of the first screen 130 , the spreading mechanism 160 may further include a panel 164 , which is connected to the side wall of the first screen 130 . The panel 164 may be used to support the spreading member 162 and the material.

[0085] Furthermore, in order to increase the spreading area, the barrier 142 can be connected to two spreading members 162 at the same time, and the two spreading members 162 are respectively located on both sides of the barrier 142. At the same time, a telescopic member 163 can be connected between the follower 161 and the spreading member 162.

[0086] When the barrier 142 moves toward the first side, it can drive the spreading member 162 on the second side of the barrier 142 to move synchronously. During this process, the telescopic member 163 on the first side is compressed, so that the spreading member 162 on the first side of the barrier 142 is abutted against the first side enclosure 164. When the barrier 142 moves toward the second side, it can drive the spreading member 162 on the first side of the barrier 142 to move synchronously. During this process, the telescopic member 163 on the second side is compressed, so that the spreading member 162 on the second side of the barrier 142 is abutted against the second side enclosure 164.

[0087] It is worth noting that the telescopic member 163 is a telescopic rod, and may also be a telescopic spring, and there is no limitation on the specific type of the telescopic member 163 .

[0088] In addition, the spreading mechanism 160 can also include a bending member 165, which is connected to the follower 161 and is S-shaped. The bending member 165 contacts the top surface of the first screen 130. During the synchronous movement of the bending member 165 and the follower 161, the S-shaped surface wall of the bending member 165 can contact the material, so that the material after contact can move in different directions, thereby realizing multi-directional spreading operations.

[0089] In this embodiment, the bending member 165 is arranged near the center of the first screen 130 relative to the flattening member 162, so that the flattening member 162 is mainly used to flatten the material at the edge position of the first screen 130 in one direction, while the bending member 165 is mainly used to flatten the material at the middle position of the first screen 130 in multiple directions.

[0090] In summary, the broad bean screening device for broad bean paste production provided by the embodiments of the present invention has at least the following advantages:

[0091] (1) It can block the materials at different positions passing through the discharge port 121 in sequence through the blocking member 142, so as to prevent all the materials from being quickly delivered to the first screen 130, reduce the probability of accumulation of the materials when they just enter the first screen 130, prevent the screening efficiency from being reduced, and avoid blockage.

[0092] (2) By providing a guide hole 1421 on the barrier 142, the barrier 142 not only has the function of blocking the material, but also facilitates part of the blocked material to pass through the guide hole 1421 and enter the first screen 130, thereby avoiding clogging of the material blocked by the barrier 142.

[0093] (3) By setting a turning member 144 to perform a turning operation on the inner side of the discharge port 121, on the one hand, it can avoid the blockage of the material blocked by the blocking member 142, and on the other hand, it promotes the dispersion of the material near the discharge port 121.

[0094] (4) The vibration mechanism 150 can be provided to promote the flow rate of the material on the first screen 130 to improve the screening efficiency.

[0095] (5) The distribution mechanism 160 can improve the distribution effect of the material on the first screen 130 , thereby preventing some materials from being squeezed onto the second screen 132 without contacting the first screen 130 when passing through the first screen 130 .

[0096] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
