[0028] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0029] Please refer to Figure 1 and Figure 2 , the broad bean screening device for broad bean paste production provided in the embodiments of the present invention can solve the above problems, and will be described in detail below.

[0030] The broad bean screening device for broad bean paste production includes a base 110, a feeding box 120, a first sieve 130 and an anti-piling mechanism 140; 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 materials output from the discharge port 121. The anti-piling mechanism 140 includes a connected driving member 141 and a blocking member 142. The driving member 141 is connected to the feeding box 120, and the blocking member 142 is movably arranged at the discharge port 121. The driving member 141 is used to drive the blocking member 142 to move along the width direction of the discharge port 121 to block part of the materials.

[0031] During the working process, the feeding box 120 is used to deliver materials towards the first screen 130 through the discharge port 121. The driving member 141 can drive the blocking member 142 to move, so that the blocking member 142 can successively block different position parts of the materials passing through the discharge port 121, avoiding all the materials being quickly delivered onto the first screen 130, reducing the probability of piling up when the materials first enter the first screen 130, preventing the screening efficiency from decreasing, and avoiding blockage.

[0032] In this embodiment, the feeding box 120 is used to hold a certain amount of materials. The discharge port 121 is located at the bottom of the feeding box 120, and the materials can slide out through the discharge port 121 under the action of their own gravity. And, in order to improve the discharge rate, the inner bottom wall of the discharge port 121 can be inclined and extend towards the lower part from the inside to the outside.

[0033] It should be noted that the device further 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 is located below the first screen 130, and is used to receive the materials leaked from the first screen 130. The second screen 132 is located on the side of the first screen 130 away from the discharge port 121. The materials that do not leak through the first screen 130 will enter the second screen 132. The mesh holes of the second screen 132 are larger than those of the first screen 130. The second material box 136 is connected to the base 110 and is located below the second screen 132, and is used to receive the materials leaked from 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. The second screen 132 can be inclined, and the materials that do not leak through the second screen 132 can smoothly enter the third material box 137 under the action of gravity.

[0034] 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 set number is not limited. Generally speaking, the farther the distance between different screens and the discharge port 121 is, the larger the size of the mesh openings opened thereon is. In addition, the length of the first screen 130 needs to be appropriate. On the one hand, it is convenient for the materials to be fully screened on the first screen 130, and on the other hand, it is convenient for the materials to move smoothly onto the second screen 132 under the action of their own inertia.

[0035] In this embodiment, the partition member 142 has a rectangular plate-like structure, and its two side walls are flat; of course, in other embodiments of the present invention, the partition member 142 can also be of other shapes, and the two side walls of the partition member 142 can be arc-shaped or wavy, and the specific outer shape and side wall shape of the partition member 142 are not limited.

[0036] Please refer to Figure 2 , in order to avoid serious blockage of the materials blocked by the partition member 142, a diversion hole 1421 can be provided in the partition member 142, so that in addition to the function of blocking the materials, the partition member 142 also facilitates a part of the blocked materials to pass through the diversion hole 1421 and enter onto the first screen 130.

[0037] Specifically, the size of the diversion hole 1421 can be adapted to the size of the mesh openings on the first screen 130, so that the materials passing through the diversion hole 1421 can leak out from the first screen 130. Of course, the size of the diversion hole 1421 can also be larger or smaller than the size of the mesh openings on the first screen 130.

[0038] In this embodiment, the diversion hole 1421 is in a long strip shape, and the long strip extending direction of the diversion hole 1421 is consistent with the height direction of the discharge port 121. By defining the shape of the diversion hole 1421 as a long strip shape, it is convenient for the materials flowing out of the diversion hole 1421 to have a sufficient height from the first screen 130, so that the materials can bounce when falling onto the first screen 130, which helps to drive local vibration of the first screen 130, and further promotes the flow of the materials on the first screen 130. And the diversion hole 1421 can be provided in multiple numbers, and the multiple diversion holes 1421 are arranged in sequence along the width direction of the discharge port 121.

[0039] It should be noted that when there are multiple diversion holes 1421, the adjacent two diversion holes 1421 can be spaced apart, or the adjacent two diversion holes 1421 can be connected.

[0040] Of course, in other embodiments of the present invention, the extending direction of the long strip of the diversion hole 1421 can be made consistent with the width direction of the discharge port 121, or a plurality of long strip-shaped diversion holes 1421 can be arranged in sequence along the height direction of the discharge port 121. It is also possible to make the diversion hole 1421 in other shapes such as circular, rectangular, or fan-shaped. The specific shape and arrangement of the diversion hole 1421 are not limited.

[0041] Please refer to Figure 2 , in order to achieve the power transmission between the driving member 141 and the baffle member 142, the anti-piling mechanism 140 may further include a first transmission member 143.

[0042] 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 extending direction of the transmission rod 1431 is consistent with the width direction of the discharge port 121, the transmission block 1432 is in screw fit with the transmission rod 1431, and the transmission plate 1433 is connected between the transmission block 1432 and the baffle member 142.

[0043] During operation, the driving member 141 is used to provide a rotational power source, drive the transmission rod 1431 to rotate, then use the screw fit to make the transmission block 1432 move along the axial direction of the transmission rod 1431, and drive the baffle block to move along the axial direction of the transmission rod 1431 (i.e., the width direction of the discharge port 121) through the transmission plate 1433, so as to achieve blocking at different positions in the width direction of the discharge port 121.

[0044] In this embodiment, the transmission rod 1431 is a screw rod, 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, which rotates by manual force application. The specific power form of the driving member 141 is not limited.

[0045] Please refer to Figure 3 , in order to avoid serious blockage of the materials blocked by the baffle member 142 and at the same time promote the dispersion of the materials near the discharge port 121, the anti-piling mechanism 140 may further include a turning member 144. The turning member 144 is connected to the driving member 141 and is rotatably arranged inside the discharge port 121.

[0046] It should be noted that the rotation axis of the turning member 144 can be parallel to the width direction of the discharge port 121, parallel to the height direction of the discharge port 121, or arranged at an angle with both the width direction and the height direction of the discharge port 121, so as to realize turning operations in different direction dimensions.

[0047] In this embodiment, the turning member 144 includes a turning shaft 1441 and a turning plate 1442. The end of the turning shaft 1441 is connected to the driving member 141. The extending direction of the turning shaft 1441 is consistent with the width direction of the discharge port 121. The turning plate 1442 is connected to the peripheral wall of the turning shaft 1441 and rotates circumferentially along the turning shaft 1441.

[0048] Wherein, the number of the turning plates 1442 can be one or more, and the specific number of the turning plates 1442 is not limited.

[0049] Please refer to Figure 2 and Figure 3 To conveniently drive the turning shaft 1441 to rotate, the anti-piling mechanism 140 can further include a second transmission member 145. Among them, the second transmission member 145 includes a driving main wheel 1451, a driving auxiliary wheel 1452 and a transmission belt 1453. The driving main wheel 1451 is coaxially connected to the driving member 141, the driving auxiliary wheel 1452 is coaxially connected to the turning shaft 1441, and the transmission belt 1453 is sleeved on the driving main wheel 1451 and the driving auxiliary wheel 1452 at the same time. The driving main wheel 1451, the driving auxiliary wheel 1452 and the transmission belt 1453 can jointly form a synchronous belt structure, and differential transmission can be realized by using the size difference between the driving main wheel 1451 and the driving auxiliary wheel 1452.

[0050] In this embodiment, a transmission rod 1431 can be connected between the driving main wheel 1451 and the driving member 141, that is, the driving main wheel 1451 and the driving member 141 are respectively coaxially connected to both ends of the transmission rod 1431.

[0051] It should be noted that the second transmission member 145 can also be a rotating handle, that is, the rotating handle is driven to rotate by manual force, and then the turning shaft 1441 rotates.

[0052] Furthermore, in order to simplify the overall structure, both sides of the turning plate 1442 can be directly connected to the transmission rod 1431, and the middle position of the turning plate 1442 is designed with a hollow to avoid the transmission block 1432. The turning plate 1442 can be a flexible sheet, and the transmission rod 1431 can drive the turning plate 1442 to rotate synchronously while rotating.

[0053] Please refer to Figure 1 、 Figure 2 and Figure 4 To promote the flow rate of the material on the first screen 130 to improve the screening efficiency, the broad bean screening device for broad bean paste production can further include a vibration mechanism 150. Among them, the vibration mechanism 150 can be one or more vibration motors, and the vibration motors are installed on the lower side of the first screen 130 to drive the first screen 130 to vibrate.

[0054] 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 partition member 142 and moves synchronously with the partition member 142. One end of the vibration inclined plate 152 is rotatably connected to the outer side wall of the discharge port 121, and 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 abuts against or moves away from the first screen 130 to drive the first screen 130 to vibrate.

[0055] Moreover, the number of the extension plates 151 is two, and the two extension plates 151 are respectively connected to both sides of the partition member 142; the number of the vibration inclined plates 152 is multiple, and the multiple vibration inclined plates 152 are arranged in sequence along the width direction of the discharge port 121.

[0056] When the partition member 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, and then drive partial positions of the first screen 130 to vibrate.

[0057] Specifically, a first arc block 1511 can be formed on the bottom wall of the extension plate 151, and a second arc block 1521 can be formed on the top wall of the end of the vibration inclined plate 152 far from the discharge port 121, and the first arc block 1511 cooperates with the second arc block 1521.

[0058] It should be noted that, in order to facilitate the reciprocating movement of the vibration inclined plate 152 when it cooperates with the extension plate 151, the vibration inclined plate 152 can be made of 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, and the elastic member 153 is connected between the outer side 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 sleeved on the rotating shaft at the position where the vibration inclined plate 152 is rotatably connected to the outer side wall of the discharge port 121; when it is a spring, one end of the spring can be connected to the outer side wall of the discharge port 121, and the other end can be connected to the position on the vibration inclined plate 152 far from the second arc block 1521.

[0059] Moreover, in order to improve the installation convenience, the outer side wall of the discharge port 121 can be provided with a lug, and the rotation connection with one end of the vibration inclined plate 152 is realized through the lug.

[0060] Please refer to Figure 1 、 Figure 5 and Figure 6, To improve the spreading effect of the materials 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 doubanjiang production may further include a spreading mechanism 160.

[0061] Specifically, the spreading mechanism 160 includes a follower 161 and a spreading member 162 connected to each other. The follower 161 is connected to the partition member 142 and moves synchronously with the partition member 142. The spreading member 162 is connected to the follower 161 and its extending direction is the same as the orientation of the discharge port 121. The spreading member 162 contacts the top surface of the first screen 130. That is, when the partition member 142 moves, it can drive the spreading member 162 to move through the follower 161, so as to realize the spreading operation through the contact between the spreading member 162 and the materials.

[0062] In this embodiment, the spreading member 162 is cylindrical, and its cylindrical extending direction is the same as the orientation of the discharge port 121. Of course, in other embodiments of the present invention, the spreading member 162 may also be in the shape of a bent connecting rod, and its specific shape is not limited.

[0063] Moreover, to prevent the materials from sliding out from both sides of the first screen 130, the spreading mechanism 160 may further include a retaining plate 164. The retaining plate 164 is connected to the side wall of the first screen 130, and the retaining plate 164 can be used to abut against the spreading member 162 and the materials.

[0064] Furthermore, to increase the spreading area, the partition member 142 may 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 partition member 142. At the same time, a telescopic member 163 may be connected between the follower 161 and the spreading member 162.

[0065] When the partition member 142 moves towards the first side, it can drive the spreading member 162 located on the second side of the partition member 142 to move synchronously. During this process, the telescopic member 163 on the first side will be compressed, so that the spreading member 162 located on the first side of the partition member 142 is abutted against the retaining plate 164 on the first side. When the partition member 142 moves towards the second side, it can drive the spreading member 162 located on the first side of the partition member 142 to move synchronously. During this process, the telescopic member 163 on the second side will be compressed, so that the spreading member 162 located on the second side of the partition member 142 is abutted against the retaining plate 164 on the second side.

[0066] It should be noted that the telescopic member 163 may be a telescopic rod or a telescopic spring, and the specific type of the telescopic member 163 is not limited.

[0067] In addition, the apportioning mechanism 160 can also include a bending member 165. The bending member 165 is connected to the follower member 161 and is S-shaped. The bending member 165 contacts the top surface of the first screen 130. During the synchronous movement with the follower member 161, the S-shaped surface of the bending member 165 can contact the material, so that the contacted material can move in different directions, thereby realizing multi-directional spreading operation.

[0068] In this embodiment, the bending member 165 is arranged closer to the center of the first screen 130 than the spreading member 162, so that the spreading member 162 is mainly used for unidirectional spreading of the material at the upper edge position of the first screen 130, while the bending member 165 is mainly used for multi-directional spreading of the material at the middle position of the first screen 130.

[0069] In summary, the broad bean screening device for doubanjiang production provided by the embodiments of the present invention has at least the following advantages: (1) It can successively block different position parts of the material passing through the discharge port 121 through the blocking member 142, avoiding all materials being quickly delivered onto the first screen 130, reducing the probability of accumulation when the material first enters the first screen 130, preventing the screening efficiency from decreasing, and avoiding blockage.

[0070] (2) By opening the diversion holes 1421 in the blocking member 142, the blocking member 142 not only has the function of blocking the material, but also facilitates part of the blocked material to pass through the diversion holes 1421 and enter the first screen 130, avoiding blockage of the material blocked by the blocking member 142.

[0071] (3) By arranging the turning member 144 to perform turning operation inside the discharge port 121, on the one hand, it can avoid 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.

[0072] (4) By arranging the vibration mechanism 150, it can promote the flow rate of the material on the first screen 130 to improve the screening efficiency.

[0073] (5) By arranging the apportioning mechanism 160, it can improve the apportioning effect of the material on the first screen 130, avoiding individual materials being squeezed onto the second screen 132 without contacting the first screen 130 when passing through the first screen 130.

[0074] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims described above.
