For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] As Figure 1-7As shown in the figure, the adjustable vibration type cleaning sieve for different kinds of grain and impurities proposed by the present utility model includes a support frame 1. An upper sieve plate 2 is arranged inside the support frame 1. A lower sieve plate 3 is arranged inside the support frame 1. A waste receiving frame 4 is arranged inside the support frame 1. A connection structure 5 is arranged inside the support frame 1. The support frame 1 is connected to the upper sieve plate 2 through the connection structure 5. A material blocking structure 6 is arranged on the right side of the upper sieve plate 2. A material guiding frame 7 is arranged on the right side of the upper sieve plate 2.

[0028] In the present utility model, the upper sieve plate 2 and the lower sieve plate 3 can be used to screen soybeans to a certain extent, removing different kinds of miscellaneous grains such as corn and impurities in the soybeans. And through the connection structure 5, the upper sieve plate 2 can be rotated, thereby adjusting the angle of the upper sieve plate 2 and further changing the screening efficiency of the upper sieve plate 2. Through the material blocking structure 6, the soybeans on the upper sieve plate 2 can be fully screened. And through the material guiding frame 7, the different kinds of miscellaneous grains such as corn on the upper sieve plate 2 can be discharged. A vibration motor is installed on the support frame 1. Through the vibration motor, the upper sieve plate 2 and the lower sieve plate 3 can be vibrated, improving the screening efficiency.

[0029] Among them, the lower sieve plate 3 is located below the upper sieve plate 2, and the waste receiving frame 4 is located below the lower sieve plate 3. During screening, the soybeans first enter the upper sieve plate 2. Through the vibration motor, the soybeans and impurities are screened into the interior of the lower sieve plate 3 by vibration. And the different kinds of miscellaneous grains such as corn are left in the interior of the upper sieve plate 2. After the soybeans and impurities enter the interior of the lower sieve plate 3, the impurities are screened into the interior of the waste receiving frame 4 by vibration through the vibration motor, while the soybeans remain in the interior of the lower sieve plate 3.

[0030] In addition, a material guiding plate 8 is arranged on the right side of the lower sieve plate 3. An impurity discharge channel 9 is arranged inside the support frame 1. The impurity discharge channel 9 corresponds to the outlet of the waste receiving frame 4. Since both the lower sieve plate 3 and the waste receiving frame 4 are inclined, during the vibration screening process, the soybeans inside the lower sieve plate 3 and the impurities inside the waste receiving frame 4 will move to the right under the action of their gravity, so that the soybeans are discharged from the material guiding plate 8 and the impurities are discharged from the impurity discharge channel 9. At the same time, the different kinds of miscellaneous grains such as corn on the upper sieve plate 2 will also move to the right.

[0031] It should be noted that the connecting structure 5 includes a rotating rod 501, two ear plates 502, two arc-shaped rods 503 and two groups of fixing components 504. The rotating rod 501 is rotatably connected to the inside of the support frame 1. The two ear plates 502 are both fixedly installed at the left bottom of the upper sieve plate 2. The two ear plates 502 are both rotatably connected to the outside of the rotating rod 501. The two arc-shaped rods 503 are both arranged inside the support frame 1. The two arc-shaped rods 503 are respectively located at the front and back of the right side of the upper sieve plate 2. The two groups of fixing components 504 are both arranged at the bottom of the upper sieve plate 2. The upper sieve plate 2 is respectively connected to the two arc-shaped rods 503 through the two groups of fixing components 504.

[0032] In an alternative embodiment, the upper sieve plate 2 can be installed inside the support frame 1 through the rotating rod 501 and the two ear plates 502. At the same time, the upper sieve plate 2 can also be rotated to adjust the inclination angle of the upper sieve plate 2. Meanwhile, the right side of the upper sieve plate 2 can be fixed through the two arc-shaped rods 503 and the two groups of fixing components 504 to ensure the stability of the upper sieve plate 2 after adjusting the angle.

[0033] It should be noted that the centers of the two arc-shaped rods 503 coincide with the rotating rod 501, so that when the upper sieve plate 2 adjusts the angle, the two arc-shaped rods 503 can guide and buffer it to avoid the situation of the arc-shaped rods 503 limiting the upper sieve plate 2.

[0034] In an alternative embodiment, the fixing component 504 includes a first fixing plate 5041, a second fixing plate 5042, a fixing bolt 5043 and a fixing nut 5044. The two first fixing plates 5041 are both fixedly installed at the bottom of the upper sieve plate 2. The two second fixing plates 5042 are respectively located on the opposite sides of the two first fixing plates 5041. The two fixing bolts 5043 are respectively arranged on the opposite sides of the two first fixing plates 5041 and extend to the opposite sides of the two second fixing plates 5042. The two fixing nuts 5044 are respectively threadedly connected to the outside of the two fixing bolts 5043. The front and back of the arc-shaped rod 503 are respectively abutted against the opposite sides of the first fixing plate 5041 and the second fixing plate 5042 on the same side. The opposite sides of the two fixing nuts 5044 are respectively abutted against the opposite sides of the two second fixing plates 5042.

[0035] It should be noted that by rotating the two fixing nuts 5044, the two second fixing plates 5042 can move towards the opposite side, so that the arc-shaped rod 503 can be tightly abutted against the corresponding first fixing plate 5041 and second fixing plate 5042, thereby fixing the upper sieve plate 2 through the first fixing plate 5041, the second fixing plate 5042 and the arc-shaped rod 503. When the angle of the upper sieve plate 2 needs to be adjusted, reverse-rotate the fixing nut 5044 to make the two second fixing plates 5042 move towards the opposite side and disengage from the arc-shaped rod 503, so that the upper sieve plate 2 can rotate, thereby adjusting the angle of the upper sieve plate 2.

[0036] In an optional embodiment, there are four groups of fixing bolts 5043 and fixing nuts 5044, and the four groups of fixing bolts 5043 and fixing nuts 5044 are respectively arranged in an array at the four corners on the opposite side of the two first fixing plates 5041.

[0037] It should be noted that the four groups of fixing bolts 5043 and fixing nuts 5044 can ensure the stability of the installation of the second fixing plate 5042, and at the same time can further ensure the stability of the abutment between the second fixing plate 5042 and the arc-shaped rod 503, thereby ensuring the stability of the installation of the upper sieve plate 2 after adjusting the angle.

[0038] Specifically, by rotating the fixing nut 5044, the two second fixing plates 5042 can move towards the opposite side or the opposite side. When the two second fixing plates 5042 move towards the opposite side and disengage from the arc-shaped rod 503, the upper sieve plate 2 can be rotated through the rotating rod 501, the two ear plates 502 and the two arc-shaped rods 503, thereby adjusting the inclination angle of the upper sieve plate 2. When the second fixing plate 5042 moves towards the opposite side and abuts against the arc-shaped rod 503, the upper sieve plate 2 can be fixed through the first fixing plate 5041, the second fixing plate 5042 and the two arc-shaped rods 503 to ensure the stability of the upper sieve plate 2 during operation.

[0039] It should be noted that when there are more foreign corn grains and impurities in the soybeans, the angle of the upper sieve plate 2 can be appropriately adjusted to make the inclination angle of the upper sieve plate 2 smaller, so that the soybeans can be screened more fully on the upper sieve plate 2, ensuring the screening effect of the soybeans. When there are fewer foreign corn grains and impurities in the soybeans, the angle of the upper sieve plate 2 can be appropriately adjusted to make the inclination angle of the upper sieve plate 2 larger. While ensuring the screening effect, the soybeans can be screened more quickly on the upper sieve plate 2, improving the screening efficiency of the soybeans.

[0040] In an alternative embodiment, the material blocking structure 6 includes two driving grooves 601, a rotating shaft 602, a baffle 603, and two torsion springs 604. The two driving grooves 601 are respectively formed on the front and rear side walls of the inner cavity of the upper sieve plate 2. The rotating shaft 602 is rotatably connected to the opposite side of the inner cavity of the two driving grooves 601. The baffle 603 is fixedly installed on the outer side of the rotating shaft 602. The baffle 603 is adapted to the right side of the upper sieve plate 2. The two torsion springs 604 are respectively fixedly installed on the opposite side of the inner cavity of the two driving grooves 601 and are both located on the outer side of the rotating shaft 602. The opposite sides of the two torsion springs 604 are fixedly connected to the outer side of the rotating shaft 602.

[0041] It should be noted that when the miscellaneous grains of different types of corn in the upper sieve plate 2 move to the right, they will accumulate on the right side of the upper sieve plate 2 under the action of the baffle 603. At this time, through the vibration of the upper sieve plate 2, the miscellaneous grains of different types of corn inside the upper sieve plate 2 can be fully screened to avoid the mixing of soybeans in the miscellaneous grains of different types of corn. When the miscellaneous grains of different types of corn accumulate to a certain extent, the miscellaneous grains of different types of corn will squeeze the baffle 603, causing the baffle 603 to rotate, so that the miscellaneous grains of different types of corn will fall into the inside of the material guiding frame 7 through the right side of the upper sieve plate 2 and be discharged. At this time, the baffle 603 will drive the rotating shaft 602 to rotate, and the rotating shaft 602 will drive the two torsion springs 604 to twist. When the miscellaneous grains of different types of corn are discharged to a certain extent, the rotating shaft 602 will rotate in the reverse direction under the resilience of the two torsion springs 604, thereby driving the baffle 603 to rotate in the reverse direction, so that the baffle 603 can block the right side of the upper sieve plate 2, further enabling the soybeans in the miscellaneous grains of different types of corn to be fully screened.

[0042] In an alternative embodiment, a feed hopper 10 is provided above the support frame 1, and a material guiding block 11 is provided inside the feed hopper 10.

[0043] It should be noted that the material guiding block 11 is composed of three material dividing plates, and the widths of the three material dividing plates gradually decrease from bottom to top. When the soybeans enter the feed hopper 10, under the action of the three material dividing plates, part of the soybeans will move towards the front and back of the material guiding block 11, so that the soybeans can evenly fall onto the upper sieve plate 2, further improving the screening efficiency of the soybeans.

[0044] In an alternative embodiment, four uniformly distributed universal wheels 12 are provided at the bottom of the support frame 1. The support frame 1 can be moved through the four universal wheels 12, so that the entire cleaning sieve can be moved, increasing the practicality of the cleaning sieve.

[0045] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
