Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] This embodiment is used to solve the problem that during the screening process of traditional bean product raw materials, a large number of bean product raw materials are wasted due to the influence of the different weights of impurities mixed in the bean products, damaged beans and bean skins that have not been separated from the bean products waiting to be screened; at the same time, there are embedded impurities in the damaged beans and bean skins that have not been separated, and the separation efficiency is low under the traditional single mechanical vibration.

[0026] See also Figure 1 - Figure 3 As shown, this embodiment is a raw material screening device for bean product processing and production, including a side frame 1, a feed frame 2 is arranged on the top of one end of the side frame 1, a vibration frame 5 is arranged at the bottom of the feed frame 2, and a sieve plate 502 is arranged at the top center of the vibration frame 5. When in use, the deflection shaft 201 is used to adjust the expansion angle of the feed hopper 2 on the vibration frame 5. The larger the expansion angle of the top of the feed hopper 2, the easier it is to guide the raw materials to roll into the sieve plate 502. The vibration motor 503 drives the sieve plate 502 to reciprocate up and down at a high frequency through the transmission member, the vibration frame 5 and the spring member, which vibrates and shakes the raw materials rolling on the surface. An air guide 506 is arranged at the bottom of the sieve plate 502, and a lightweight suction mechanism 3 is arranged above the sieve plate 502. The lightweight suction mechanism 3 includes an exhaust fan 303 and a plurality of groups of internal suction ports 301, and an internal collection bin 6 is arranged below the sieve plate 502.

[0027] The attachments, impurities and unshed bean skins on the surface of the raw materials are caused to fall off one by one, and affected by the inclination angle of the sieve plate 502, the defective particles and good particles after vibration are caused to fall into the cone silo 304, among which the heavier impurities and smaller raw material fragments fall into the inner collection bin 6 along the cone mouth 505; a deflection shaft 201 connected to the vibration frame 5 is arranged at the bottom of the feeding frame 2, a vibration motor 503 is arranged inside one end of the vibration frame 5, and a spring rod 501 connected to the sieve plate 502 is arranged at the top of the vibration frame 5;

[0028] The air guide pipe 506 is connected to the exhaust fan 303, and a fixed pipe sleeve 507 facing the sieve plate 502 is arranged on the top of the air guide pipe 506. When the exhaust fan 303 is started, the exhaust fan 303 is connected to the air guide pipe 506 and the jet port 306 through some pipe fittings to provide a jet airflow for the two. The exhaust fan 303 is connected to the conveying pipe 302, the V-shaped suction plate 602, the lightweight suction plate 606 and the crushed material suction plate 609 through some pipe fittings to provide a negative pressure suction airflow for the four. The top surface of the sieve plate 502 is provided with a plurality of groups of cone ports 505 and aeration ports 504 arranged in a mutually staggered manner. The bottom of the cone port 505 faces the inner collection bin 6. The bottom of the aeration port 504 is provided with a sliding pipe sleeve 508 slidably connected to the fixed pipe sleeve 507, and adjacent surfaces of the fixed pipe sleeve 507 and the sliding pipe sleeve 508 are symmetrically provided with staggered through ports.

[0029] The air guide pipe 506 guides the jet air flow to be dispersed into multiple groups of fixed pipe sleeves 507. When the sieve plate 502 drives the sliding pipe sleeve 508 to slide down synchronously, the surface opening of the sliding pipe sleeve 508 docks with the upper opening of the fixed pipe sleeve 507, and the jet air flow flows into the aeration pipe along the opening, prompting the aeration pipe to intermittently guide the jet air flow to blow the passing raw materials, causing the raw materials to roll under the mechanical vibration of the sieve plate 502 and then be pushed by the air flow, and the light objects that fall off are blown to the inner suction port 301 by the air flow.

[0030] Example 2: Please refer to Figure 1 , Figure 4 , Figure 5 As shown, a raw material screening device for bean product processing and production in this embodiment includes a V-shaped guide frame 607 arranged at the bottom of one end of the inner collecting bin 6, a V-shaped suction plate 602 close to the exhaust fan 303 is arranged at the top of the other end of the inner collecting bin 6, and a defective product channel 7 and a good product channel 8 are arranged below the V-shaped suction plate 602. The conveying pipe 302 is connected with multiple groups of inner suction ports 301, and the multiple groups of inner suction ports 301 form multiple groups of negative pressure environments above the sieve plate 502, so as to suck the flying light objects, and convey them to the inner collecting bin 6 along the conveying pipe 302 under the extraction pressure of the exhaust fan 303, and the light objects, heavier impurities, and smaller raw material fragments in the inner collecting bin 6 are collected in the collecting port area, and fall down under the traction of the self-weight, the light suction plate 606 and the suction airflow of the fragment suction plate 609;

[0031] When passing through the outer folding plate 605, the light objects are concentrated in the channel between the outer folding plate 605 and the V-shaped guide frame 607 due to the small negative pressure suction environment of the light air extraction plate 606, so as to realize the centralized discharge of the light objects.

[0032] When passing through the crusher guide plate 608, the smaller raw material particles are deflected by the airflow and enter the crusher guide plate 608 due to the large negative pressure suction environment of the crusher suction plate 609, thereby realizing the centralized discharge of the smaller raw material particles.

[0033] A conveying pipe 302 connecting the exhaust fan 303 and the inner collection bin 6 is arranged at the top of the inner suction port 301, a vertical plate 308 located at the other end of the vibration frame 5 is arranged outside the exhaust fan 303, a conical bin 304 is arranged in a depression at one end of the vertical plate 308 close to the vibration frame 5, and a plurality of groups of air jets 306 facing the defective product channel 7 are opened on the inner wall of the conical bin 304, a plurality of groups of thin sheets 305 are staggered on the inner wall of the conical bin 304, and a soft cushion 307 close to the good product channel 8 is arranged on the inner wall of the bottom of the conical bin 304;

[0034] A plurality of cone frames 601 close to the vibration frame 5 are arranged on the top of the inner collecting bin 6, a collecting port located above the V-shaped guide frame 607 is arranged at the bottom of one end of the inner collecting bin 6, an outer folding plate 605 is arranged obliquely on the top of one end of the V-shaped guide frame 607, and a light air extraction plate 606 is arranged on the inner wall of the bottom of the outer folding plate 605; a crushed material guide plate 608 is arranged at the bottom of the other end of the V-shaped guide frame 607, and a crushed material suction plate 609 is arranged on the inner wall of the crushed material guide plate 608, a filter screen 603 is arranged at the bottom of the V-shaped suction plate 602, and a material guide plate 604 extending to the top of the crushed material guide plate 608 is arranged at the bottom of the V-shaped suction plate 602;

[0035] When the defective particles and the qualified particles fall into the conical silo 304, they come into contact with the thin sheets 305 arranged at different positions and angles, and are guided to gradually disperse under the influence of the positions and angles of the thin sheets 305. When the defective particles and the qualified particles pass through the area of ​​the air jet 306, they are affected by the jet airflow guided by the air jet 306, causing the lighter defective particles to be affected by the jet airflow and blown into the defective channel 7, and then guided by the defective channel 7 to be discharged. The heavier qualified particles are less affected by the jet airflow and fall onto the soft cushion 307. After being buffered by the soft cushion 307, they fall into the good channel 8 and are discharged in a concentrated manner.

[0036] Combining Example 1 and Example 2, it is possible to promote the full movement of the soy product raw materials on the screen plate 502, so that the surface attachments and defective particles fall off and separate, thereby realizing the preliminary screening of the soy product raw materials, and to separate the defective particles from the good particles. After the light and heavy materials separated from the raw materials are concentrated in the internal collecting bin 6, the light materials, heavier impurities, and raw material fragments of a certain weight are pneumatically diverted under the action of different suction forces.

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the invention or exceed the scope defined by the claims, they should all fall within the protection scope of the present invention.
