[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0019] See also Figures 1 to 4 The utility model provides a technical solution: a raw material filter screen, comprising a shell 1, a connecting groove 11 is provided at the middle position of the inner wall of the bottom end of the shell 1, a discharge port 12 and a feed port 13 are sequentially provided on the outer surface of one side of the shell 1, and a limit plate 14 is fixedly installed on the inner walls of both sides of the shell 1, and a motor 2 is provided at the middle position of the top end of the shell 1;

[0020] The output end of the motor 2 is connected to the mounting plate 21 through a rotating shaft transmission. A groove is provided on the top inner wall of the shell 1 near the rotating shaft, and the rotating shaft passes through the top inner wall of the shell 1 through the groove and extends to the interior of the shell 1. Three groups of stirring members 22 are fixedly installed on the bottom end of the mounting plate 21. The three groups of stirring members 22 are equal in size and are axially symmetrically arranged. The two groups of limit plates 14 are equal in size and are axially symmetrically arranged.

[0021] The bottom ends of the two groups of limit plates 14 are arranged at the same horizontal height as the bottom ends of the three groups of stirring members 22. Two groups of electric push rods 4 are fixedly installed at the bottom end of the shell 1. One ends of the two groups of electric push rods 4 are movably hinged to the bottom end of the placement plate 3. The movable connection ensures that the end of the electric push rod 4 can rotate with the placement plate 3, and when the electric push rod 4 is working, when it shrinks or extends, the end of the electric push rod 4 can move along the surface of the placement plate 3, thus meeting the movement needs of a single group of electric push rods 4 when working.

[0022] A filter screen 31 is arranged inside the placement plate 3, and both ends of the filter screen 31 are designed with arc-shaped edges. An elastic rubber plate is arranged on the end of the discharge port 12 facing the filter screen 31, because when the electric push rod 4 shrinks up and down, the filter screen 31 will make an arc movement, and the elastic rubber plate is used to connect the falling material of the filter screen 31;

[0023] A collecting trough 32 is fixedly installed at the bottom end of the placement plate 3, and a discharge pipe 34 is connected to the bottom end of the collecting trough 32. The outer diameter of the discharge pipe 34 is adapted to the inner diameter of the connecting groove 11, and the discharge pipe 34 is vertically and parallelly arranged to the connecting groove 11. A control valve is arranged on the outer surface of one end of the discharge pipe 34, and triangular blocks 33 are arranged on both sides of the inner wall of the bottom end of the collecting trough 32 near the discharge pipe 34. The two groups of triangular blocks 33 are equal in size, and the two groups of triangular blocks 33 are axially symmetrically arranged, and one side of the two groups of triangular blocks 33 is fitted with the top end of the discharge pipe 34. A collecting box 5 is fixedly installed on the outer surface of one side of the shell 1 near the bottom end, and an impurity port 51 is arranged on the outer surface of one side of the collecting box 5.

[0024] The user can first put the wheat seeds into the shell 1 through the feed port 13, and they will automatically fall onto the top surface of the placement plate 3. At this time, the user can start the motor 2, and the mounting plate 21 can be rotated under the action of the motor 2, so that the three groups of stirring members 22 will rotate accordingly, so that the wheat seeds can be stirred. During the stirring process, the wheat raw materials will fall into the inside of the collecting trough 32 through the filter screen 31. The setting of the two groups of limit plates 14 can prevent the wheat seeds from scattering from both sides of the placement plate 3 during the stirring process. When the stirring and screening is completed, the user can start the two groups of electric push rods 4 in succession and adjust them to the following: Figure 3 The position shown in the figure can be obtained. At this time, the straw impurities will pass through the discharge port 12 under the action of the oblique force and finally fall into the interior of the collection box 5 for collection. When cleaning is needed, the impurities can be taken out by simply opening the impurity port 51. When the impurities inside the aggregate trough 32 are collected to a certain extent, the user can adjust the two sets of electric push rods 4 to the lowest end. At this time, the discharge pipe 34 will pass through the inner wall of the bottom end of the shell 1 through the connecting groove 11, and then the control valve located on the outer surface of the discharge pipe 34 can be opened to discharge the wheat raw materials inside the aggregate trough 32. The setting of the two sets of triangular blocks 33 can make it easier to discharge the wheat inside the aggregate trough 32 to a certain extent, and prevent the wheat from being difficult to discharge inside the aggregate trough 32.

[0025] Working principle: During use, the user can first put the wheat raw material into the shell 1 through the feed port 13, and it will automatically fall onto the top surface of the placement plate 3. At this time, the user can start the motor 2, and the mounting plate 21 can be rotated under the action of the motor 2, so that the three groups of stirring members 22 will rotate accordingly, so that the wheat seeds can be stirred. During the stirring process, wheat particles with small diameters will pass through the filter screen 31 and fall into the inside of the collecting trough 32. The setting of the two groups of limit plates 14 can prevent the wheat seeds from scattering from both sides of the placement plate 3 during the stirring process. When the stirring and screening is completed, the user can start the two groups of electric push rods 4 in succession and adjust them to the following positions: Figure 3The position shown in the figure is sufficient, at which time the straw impurities will pass through the discharge port 12 under the action of the oblique force and finally fall into the interior of the collection box 5 for collection.
