[0002] Grain vibration cleaning screen is a processing equipment for vibrating and screening grains. It uses a vibration motor to drive the screen to vibrate back and forth to assist in conveying and screening the grain. It is used to remove large, medium, small and light impurities and take out the impurity particles mixed in the grain. By equipping it with sieve holes of different specifications, the material can be classified according to particle size.

[0003] At present, when the vibrating cleaning screen is working, some soil particles may exist inside the grain.

[0026] Reference Figure 1-3 , wherein a feed inlet 21 is provided at the top of the screen box 2, a discharge port 22 is provided at the right side of the screen box 2, a slag discharge port 23 is provided at the bottom of the screen box 2, a cover door 12 is installed at the feed inlet 21, and a curtain 13 is installed at the discharge port 22;

[0027] Through the above-mentioned structural arrangement, grain enters the interior of the screen box 2 from the feed inlet 21, and after being screened by the screen 3, dirt and dust fall from the slag discharge port 23, and grain is discharged from the discharge port 22. During the processing, the cover door 12 and the curtain 13 are used to close the feed inlet 21 and the discharge port 22, so that the dirt and dust either float upward and are sucked by the negative pressure fan 7, or fall downward together with the screened dirt and dust from the slag discharge port 23.

[0028] Reference Figure 2-3, wherein the driving assembly 6 includes a driving motor 61, the driving motor 61 is fixedly installed on the outside of the screen box 2, the output end of the driving motor 61 and the squeezing roller 5 penetrate to one end of the outside of the screen box 2, and are connected by a pulley 62;

[0029] Through the above-mentioned structural arrangement, after the grain falls onto the screen 3, the drive motor 61 is started, and the drive motor 61 drives the squeezing roller 5 to rotate through the pulley 62. A rubber sleeve is installed on the outside of the squeezing roller 5. The rubber sleeve can crush the agglomerated soil on the screen 3, so that the crushed soil falls from the mesh with the vibration, while reducing the damage to the grain during squeezing, thereby ensuring the integrity of the grain.

[0030] Reference Figure 2-5 , wherein the moving assembly 8 includes an electric slide rail 81, and the electric slide rails 81 are symmetrically installed on the left and right sides of the screen box 2, and the two electric slide rails 81 are slidably installed with electric sliders 82, and the two electric sliders 82 are fixedly connected to the mounting frame 9;

[0031] Through the above-mentioned structural arrangement, the electric slide rail 81 drives the mounting frame 9 to move back and forth through the electric slider 82, so that the telescopic assembly 10 drives the piercing rod 11 to clean the mesh.

[0034] Reference Figure 2-5 , wherein a stabbing rod 11 is fixedly installed on the top of the placement rack 102, the stabbing rod 11 is staggeredly installed in two rows, and the position is aligned with the position of the mesh, the head of the stabbing rod 11 is oval, and the thickness of the stabbing rod 11 is the same as the size of the mesh;

[0035] Through the above-mentioned structural setting, the staggered piercing rods 11 can avoid being arranged too densely in parallel, resulting in no gaps between the piercing rods 11 to affect each other, which affects the cleaning of the mesh. The piercing rods 11 with the right mesh size can make the cleaning effect of the mud clogging inside the mesh better.

[0036] Working principle:

[0037] The first step to implement the innovation point:

[0038] Step 1: Pour the grain from the feed port 21 onto the screen 3, then start the vibration motor 4 to start vibrating the grain in the screen box 2. When the grain vibrates on the screen 3, start the drive motor 61, which drives the squeeze roller 5 to rotate through the pulley 62, so that the squeeze roller 5 crushes the soil on the screen 3, and the crushed soil falls from the mesh with the vibration;

[0039] Step 2: When the mesh of the screen 3 is clogged, the electric slide rail 81 drives the mounting frame 9 to move back and forth through the electric slider 82, and the two lifting cylinders 101 are started. The telescopic rod 101 drives the placement frame 102 to move up and down, and the placement frame 102 drives the piercing rod 11 on the top to clean the mesh.
