The driving wheel 92 is rotatably connected to the surface of the threaded sleeve 91. The threaded screw 93 is rotatably connected to the inner wall of the threaded sleeve 91 and is connected to one end of the central axis of the driving wheel 92. The limiting rod 94 is horizontally slidably connected to the inner wall of the threaded sleeve 91 and is threadedly connected to the outer surface of one end of the threaded screw 93. The end of the limiting rod 94 away from the threaded sleeve 91 penetrates into the waist-shaped fixing hole 8 and is clamped and fixed to the inner wall of the waist-shaped fixing hole 8.

[0029] It should be noted that the material guide rack 72 is used to guide the material on the screen frame 71 to the position of the discharge seat 73.

[0030] It should also be noted that a limiting portion is provided on the limiting rod 94, and the limiting portion is used to ensure that the limiting rod 94 moves horizontally.

[0031] Specifically, the structure and connection relationship of the screen plate 7 and the locking mechanism 9 are further explained, wherein the screen frame 71, the guide frame 72 and the discharge seat 73 are integrally designed for easy disassembly and assembly, which effectively improves the installation efficiency and has a good use effect. When in use, the screen frame 71 is completely pushed into the interior of the limiting guide frame 6, and then the driving wheel 92 is rotated.

[0032] In one embodiment of the present invention, Figure 3 As shown, a rubber sleeve 95 is sleeved on one end surface of the limiting rod 94 that passes through the waist-shaped fixing hole 8 .

[0033] Specifically, the rubber sleeve 95 and the waist-shaped fixing hole 8 cooperate with each other, so that the vibration force transmitted to the limiting plug rod 94 can be effectively reduced, and the use effect is good.

[0034] In one embodiment of the present invention, Figure 3 As shown, the locking mechanism 9 also includes a synchronous drive mechanism 10, which includes a base 101, a drive spindle 102, a worm portion 103 and a mounting handle 104, wherein the base 101 is symmetrically fixedly connected to the surface of the screen frame 2, the drive spindle 102 is rotatably connected to the inner wall of the base 101, and is located on one side of the drive wheel 92, the worm portion 103 is integrally formed and arranged on the surface of the drive spindle 102, and corresponds to the position of the drive wheel 92, the drive wheel 92 is a worm wheel, the worm portion 103 is meshed with the worm wheel, one end of the drive spindle 102 passes through the top of the base 101, and is fixedly connected to the mounting handle 104.

When the worm gear part 103 rotates, it will synchronously drive the worm gear to rotate, and the rotation of the worm gear synchronously drives the threaded screw 93 to rotate.

[0036] In one embodiment of the present invention, Figure 3-Figure 4As shown, the locking mechanism 9 also includes a separation mechanism 11, which includes a straight key groove 111, a straight key shaft 112, an elastic clip 113 and a finger groove 114, wherein the straight key groove 111 is respectively opened on the surface of the driving wheel 92 and the surface of the threaded screw 93, and the positions are corresponding, the straight key shaft 112 is slidably connected to the inner wall of the straight key groove 111, and the elastic clip 113 and the clip hole are respectively provided at the corresponding positions of the surface of the straight key shaft 112 and the inner wall of the straight key groove 111, the elastic clip 113 is fixedly connected to the clip hole, and the finger groove 114 is opened on the surface of one end of the straight key shaft 112.

[0037] It should be noted that, in order to facilitate the reinsertion of the straight key shaft 112 into the straight key slot 111 , the maximum number of rotations of the driving wheel 92 is one circle.

[0038] It should also be noted that there are multiple groups of card holes.

[0039] Specifically, the separation mechanism 11 is provided to separate the driving wheel 92 from the threaded screw 93, so as to facilitate the control of the installation state of one group of sieve plates 7 separately, and the use effect is good.

[0040] When in use, the finger is inserted into the finger groove 114, and then the straight key shaft 112 is pulled outward. When the pulling force is greater than the clamping force of the elastic clamp 113, the elastic clamp 113 is separated from the clamping hole. After the elastic clamp 113 is separated from the clamping hole, the straight key shaft 112 can slide along the inner wall of the straight key groove 111. When one end of the straight key shaft 112 is separated from the straight key groove 111 on the surface of the threaded screw 93, the connection between the drive wheel 92 and the threaded screw 93 is disconnected, and the rotation of the drive wheel 92 will no longer synchronously drive the threaded screw 93 to rotate.
