The following is a description of the embodiments of the present invention based on its overall structure.

[0027] See also Figure 1 and Figure 4A scraper soybean meal screening assembly includes multiple scrapers 1, a transmission member 2, a screening plate 3, a material beating barrel 4, a purge unit 5 and a feed trough 6, wherein the screening plate 3 is arranged in the feed trough 6, and the screening plate 3 is connected above the material beating barrel 4. Multiple scrapers 1 are arranged on the upper surface of the screening plate 3, and the multiple scrapers 1 are connected through the transmission member 2, and the transmission member 2 can drive the scrapers 1 to move on the screening plate 3. Screening holes 30 are provided on the screening plate 3, and the screening holes 30 are used to screen soybean meal. The material beating barrel 4 is used to load the screened soybean meal. The purge unit 5 is used to purge the screening holes 30 when the screening holes 30 are blocked. One end of the feed trough 6 is used for feeding, and the other end of the feed trough 6 is connected with a collecting barrel.

[0028] Specifically, the collecting bucket is used to collect the screened agglomerated soybean meal, and the screening plate 3 is set as a rectangular screening plate. One end of the feeding trough 6 is used for feeding, and the soybean meal moves in the feeding trough 6 as the transmission member 2 drives the scraper 1 to move on the screening plate 3. The soybean meal without agglomeration falls into the material bucket 4 through the screening hole 30 during the movement, while the agglomerated soybean meal is left on the screening plate 3 and enters the collecting bucket at the other end of the feeding trough 6 under the drive of the scraper 1. The screened soybean meal in the material bucket 4 can be directly filled and packaged, which solves the problem of agglomeration of soybean meal during filling and packaging in the prior art.

[0029] See also Figure 3 In a preferred embodiment, the sieve holes 30 on the sieve plate 3 are rectangular sieve holes, and both ends of the rectangular sieve holes are semicircular, and the plurality of sieve holes 30 are inclined to the edge of the sieve plate 3.

[0030] For details, see Figure 3 and Figure 4 The first row of sieve holes 30 and the second row of sieve holes 30 on the sieve plate 3 have different inclination angles. This arrangement can maximize the use of the upper surface area of ​​the sieve plate 3 to set the sieve holes, thereby ensuring that more soybean meal can be screened.

[0031] See also Figure 1In a preferred embodiment, the purge unit 5 includes a purge pipe 51 and a control valve 53 and an air gun 54 connected to the purge pipe 51, the purge pipe 51 is connected to a gas supply tank 52, the gas supply tank 52 is used to provide purge gas, the control valve 53 is used to control the gas flow on the purge pipe 51, and the air gun 54 is used to spray high-pressure gas to the screening hole 30. Specifically, the gas supply tank 52 can be flexibly set at the production site, and the length of the purge pipe 51 can also be flexibly set to facilitate the purge of the screening hole 30. The purpose of purging is that when the screening hole 30 is blocked due to long-term operation, the air gun 54 can be used to purge the screening hole 30 to blow away the soybean meal blocked on the screening hole 30.

[0032] See also Figure 2 In a preferred embodiment, a groove 10 is formed on the scraper 1 at a portion in contact with the screen plate 3 , and the transmission member 2 is connected to the side of the groove 10 so that there is a gap between the transmission member 2 and the upper surface of the screen plate 3 .

[0033] Specifically, the groove 10 formed on the scraper 1 can prevent the transmission member 2 from directly contacting the upper surface of the screen plate 3, thereby preventing contact wear between the transmission member 2 and the screen plate 3. In the prior art, the scraper 1 is not provided with the groove 10, and the transmission member 2 is directly in contact with the screen plate 3. During the transportation of soybean meal, the transmission member 2 is easily worn, resulting in that the driving device of the transmission member 2 is difficult to match with the transmission member 2, and the transmission member 2 often needs to be repaired before it can be driven to move. The provision of the groove 10 reduces the repair efficiency.

[0034] See also Figure 1 and Figure 2 In a preferred embodiment, the transmission member 2 includes a plurality of transmission units, one transmission unit is connected between each two adjacent scrapers 1, each transmission unit includes three fixed blocks 21, three rotating blocks 22 and two connecting rods 23, the three fixed blocks 21 and the three rotating blocks 22 are horizontally arranged on the screening plate 3, the rotating blocks 22 are rotatably connected to the fixed blocks 21, the leftmost fixed block 21 of the transmission unit is connected to the scraper 1, and the rightmost fixed block 21 of the transmission unit is connected to the adjacent scraper 1; wherein, one end of one connecting rod 23 is connected to the middlemost rotating block 22 of the transmission unit, and the other end is connected to the scraper 1; another connecting rod 23 is connected to the middlemost fixed block 21 of the transmission unit, and the other end is connected to the adjacent scraper 1.

The driving device drives the transmission unit to move, thereby driving the scraper 1 to move, and the soybean meal left on the screening plate 3 is confined between the scrapers 1 and finally transported away. The driving device adopts the driving device corresponding to the existing middle scraper.

[0037] See also Figure 1 and Figure 2 The left side of the feed trough 6 is used as the feeding end, and the right side of the feed trough 6 is used as the discharging end.
