The rotating assembly 24 is installed on the support seat 211. The flat screen 23 is arranged just above the dust collecting trough 22 and is aligned with the rotating assembly 24 is connected; the screening device 3 further comprises a second bottom plate 31, an inclined screen 32, a collection trough 33, and a reciprocating swinging assembly 34; the second bottom plate 31 is connected to the first bottom plate 21; the collection trough 33 is arranged in the middle position of the second bottom plate 31; the inclined screen 32 is arranged above the collection trough 33; the reciprocating swinging assembly 34 is arranged on the side of the collection trough 33 and is connected to the inclined screen 32; the feed trough 12 is located above the flat screen 23; the rear end of the inclined screen 32 is located at the lower side of the front end of the flat screen 23; the front end of the collection trough 33 is provided with a loading trough 4.
[0028] In this embodiment, the rotating motor 241 drives the rotating rod 242 to perform synchronous circular motion.
[0029] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the device mainly screens out the pebbles and dust mixed in the broad beans through the dust screening device 2. The dust screening device 2 is composed of a first bottom plate 21, a dust collecting trough 22, a flat screen 23, and a rotating component 24. The dust collecting trough 22 is used to collect the screened debris and pebbles. The rotating component 24 drives the flat screen 3 to move, and the broad beans contained in the flat screen 3 jump, and the pebbles can easily pass through the circular sieve holes 231.
[0030] In this embodiment, the rotating assembly 24 includes: a rotating motor 241, a rotating rod 242, and a rotating shaft 243. The rotating motor 241 is installed at the upper end of the support seat 211 and is distributed on the front and rear sides of the dust collecting trough 22. A total of four are arranged. The rotating shaft 243 is arranged on the side of the flat screen 23 corresponding to the position of the rotating motor 241. The rotating motor 241 and the rotating shaft 243 are connected through the rotating rod 242.
[0031] See also Figure 2 As shown, the support seat 211 raises the rotating motor 241, so that a height difference is formed between the flat screen 32 and the inclined screen 32. The rotating motor 241 drives the rotating rod 242 to perform a circular motion, and the rotating rod 242 drives the flat screen 23 to complete the same motion, causing the broad beans loaded thereon to jump.
[0032] In this embodiment, the flat screen 23 is provided with a plurality of circular sieve holes 231, the diameter of the circular sieve holes 231 is less than 5 mm, and the distribution range of the circular sieve holes 231 extends from the rear end to the position where the rotating rod 242 is set at the front end, and no circular sieve holes 231 are set near the inclined screen 32.
[0033] See also Figure 4 As shown, the diameter of the circular sieve hole 231 is less than 5 mm, and broad beans cannot pass through it, but small stones can easily pass through it, so when the rotating component 24 drives the flat screen 23 to move, the stones also jump along with it, and when falling, the stones fall from the circular sieve hole 231 into the dust collecting trough 22.
[0034] At the same time, the distribution range of the circular sieve holes 231 extends from the rear end to the position where the rotating rod 242 is set at the front end. No circular sieve holes 231 are set near the inclined screen 32. Since the rotating component 24 drives the flat screen 23 to move, the flat screen 23 will have forward and backward movement states. When the flat screen 23 moves to the rear end, in order to ensure that the flat screen 23 at the front end is still above the inclined screen 32 and to facilitate the movement of the broad beans onto the inclined screen 32, some of the flat screens 23 at the front end are not set with circular sieve holes 231, and at the same time, the length of the flat screen 23 is extended so that it always remains above the inclined screen 32.
[0035] Example 2
[0036] See also Figures 1 to 6 The utility model discloses a broad bean screening machine, comprising: a feeding device 1, a dust screening device 2, and a screening device 3. The feeding device 1 is provided with a hopper 11, and a feeding trough 12 is provided on the side. The dust screening device 2 is composed of a first bottom plate 21, a dust collecting trough 22, a flat screen 3, and a rotating assembly 24. The dust collecting trough 22 is arranged in the middle of the first bottom plate 21, and a support seat 211 is vertically provided on the side of the first bottom plate 21. The rotating assembly 24 is installed on the support seat 211. The flat screen 23 is arranged just above the dust collecting trough 22 and is aligned with the rotating assembly 24 is connected; the screening device 3 further comprises a second bottom plate 31, an inclined screen 32, a collection trough 33, and a reciprocating swinging assembly 34; the second bottom plate 31 is connected to the first bottom plate 21; the collection trough 33 is arranged in the middle position of the second bottom plate 31; the inclined screen 32 is arranged above the collection trough 33; the reciprocating swinging assembly 34 is arranged on the side of the collection trough 33 and is connected to the inclined screen 32; the feed trough 12 is located above the flat screen 23; the rear end of the inclined screen 32 is located at the lower side of the front end of the flat screen 23; the front end of the collection trough 33 is provided with a loading trough 4.
[0037] In this embodiment, the reciprocating swing assembly 34 includes: a driving motor 341, a swing shaft 342, a long rod 343, and a short rod 344. The driving motor 341 is arranged on the front and rear sides of the aggregate trough 33 and installed on the second bottom plate 31, and there are four of them in total. The swing shaft 342 is arranged on the side of the inclined screen 32 and is divided into two groups, one group is arranged at the upper end of the inclined screen 32, and the other group is arranged at the lower end of the inclined screen 32. The swing shaft 342 at the upper end is connected to the driving motor 341 through the long rod 343, and the swing shaft 342 at the lower end is connected to the driving motor 341 through the short rod 344.
[0038] See also Figure 1 , Figure 4 As shown, the screening device 3 is the main device for screening the size of broad beans. The screening device 3 includes a second bottom plate 31, an inclined screen 32, a collection trough 33, and a reciprocating swing assembly 34. The second bottom plate 31 is connected to the first bottom plate 21. The collection trough 33 is arranged in the middle position of the second bottom plate 31. The inclined screen 32 is arranged above the collection trough 33. The reciprocating swing assembly 34 is arranged on the side of the collection trough 33 and is connected to the inclined screen 32. The broad beans fall from the flat screen 23 to the inclined screen 32, and the small broad beans fall into the collection trough 33 from the elliptical screen holes 321, and the large broad beans continue to slide downward to reach the loading trough 4.
[0039] In this embodiment, the driving motor 341 drives the long rod 343 and the short rod 344 to swing back and forth at a small angle, and the swing angles of the long rod 343 and the short rod 344 are the same and synchronous.
[0040] See also Figure 4 As shown, the reciprocating swing assembly 34 makes a small angle reciprocating swing. Due to the special structure of the inclined screen and the cooperation between the long rod 343 and the short rod 344, the inclined screen 32 moves back and forth horizontally, causing the broad beans on it to bounce and bounce, and small broad beans are more likely to fall into the aggregate trough 33 from the elliptical screen hole 321.
[0041] In this embodiment, a flat plate 35 is provided at the lower end of the inclined screen 32 , and the flat plate 35 is parallel to the second bottom plate 31 and is located above the charging trough 4 .
[0042] See also Figure 4 A flat plate 35 is provided to transport the large broad beans that fall to the bottom to the loading trough 4.
[0043] In this embodiment, a plurality of elliptical sieve holes 321 are evenly distributed on the inclined sieve 32 , and the elliptical sieve holes 321 are capsule-shaped. The flat plate 35 is not provided with the elliptical sieve holes 321 .
[0044] See also Figure 4As shown, the elliptical sieve hole 321 is set to a capsule shape, so that the elliptical sieve hole 321 is similar to the shape of broad beans, so that flat small broad beans can pass through more easily, while plump large broad beans cannot pass through. Since the inclined screen 32 is driven by the reciprocating swing component 34, the large broad beans are not easily stuck in the elliptical sieve hole 321.
[0045] In this embodiment, the loading trough 4 is welded together with the second bottom plate 31, the first bottom plate 21 and the second bottom plate 31 are connected by a connecting plate 5, and the first bottom plate 21 and the lower base of the feeding device 1 are also connected by a connecting plate 5.

[0046] See also Figure 6 In order to combine the feeding device 1, the dust screening device 2, and the screening device 3, the three parts are connected by a connecting piece 5. Through holes are opened at the left and right ends of the connecting piece 5. The first bottom plate 21, the second bottom plate 31, and the connecting positions corresponding to the lower end base of the feeding device 1 are opened with threaded holes.
