[0002] Grain is the main source of calories needed by the human body. Grain processing refers to the business activity of converting raw grain into semi-finished grain or finished grain, or converting semi-finished grain into finished grain. During the grain processing process, grain crops such as corn, wheat, and soybeans must be screened to remove impurities such as skin, branches and leaves.

[0003] In the prior art, when using a vibrating screen to screen grains, the operator uses a shovel to scoop up the grains and place them on the vibrating screen. The grains are moved to the screen for screening under the guidance of the vibrating screen. The vibrating screen generally has a certain height. When scooping up the grains, the operator needs to scoop up the grains and lift them up to place them on the vibrating screen, which consumes a lot of physical strength of the operator. For this reason, we have designed a vibrating screen for grain processing to solve the above problems. Utility Model Content

Through the setting of the adjusting mechanism, when screening different grains, the threaded rod 10 can drive the limiting plate 9 to slide to adjust the size of the opening on the blocking frame 8, so as to control the falling speed of different grains and ensure the screening effect;

[0023] A placement mechanism is provided between the two chutes 5, and the side wall of the placement mechanism abuts against the side wall of the U-shaped plate 4. The placement mechanism includes a slider 17 slidably connected in the two chutes 5, and a placement frame 19 is fixedly installed between the two sliders 17. A discharge port 20 is provided through the side wall of the placement frame 19, and the side wall of the placement frame 19 abuts against the side wall of the U-shaped plate 4.

[0024] A plurality of guide wheels 7 are rotatably connected to the mounting frame 3 and the U-shaped plate 4. A pulling mechanism is provided on the inner top of the mounting frame 3. The pulling mechanism passes through each guide wheel 7 and is fixedly connected to the top of the placement mechanism. The pulling mechanism includes a sliding frame 11 slidably connected to the inner top of the mounting frame 3. A pull rope 13 is fixedly connected to the side wall of the sliding frame 11. The pull rope 13 passes through each guide wheel 7 and is fixedly connected to the top of the placement frame 19.

[0025] A driving mechanism is provided on the front side wall of the mounting frame 3, which extends into the pulling mechanism and is slidably connected thereto. The driving mechanism includes a conveyor belt 6 installed on the front side wall of the mounting frame 3, a driving rod 12 is fixedly installed on the front side wall of the conveyor belt 6, the driving rod 12 extends into the sliding frame 11 and is slidably connected thereto, a driving motor 14 is fixedly installed on the front side wall of the mounting frame 3, a transmission wheel 15 is fixedly installed on the end of the output shaft of the driving motor 14, and a transmission belt 16 is transmission-connected between the transmission wheel 15 and the rotating shaft of the conveyor belt 6.

[0026] The functional principle of the utility model can be explained through the following operation modes:

[0027] When it is necessary to screen the grain, first, the operator rotates the threaded rod 10, and the threaded rod 10 drives the limiting plate 9 to slide up and down, and adjusts the opening size on the blocking frame 8 to adjust the falling speed of the grain to be screened. After the adjustment is completed, the operator shovels the grain and puts it into the placement frame 19, starts the vibrating screen body 2 and the driving motor 14, and the driving motor 14 drives the transmission wheel 15 to rotate clockwise, and the transmission wheel 15 drives the conveyor belt 6 to rotate through the transmission belt 16, and the conveyor belt 6 drives the driving rod 12 to rotate. When the driving rod 12 moves to the left on the conveyor belt 6, the driving rod 12 squeezes the sliding frame 11 to slide to the left, and the sliding frame 11 is pulled by the rope 13 pulls the placement frame 19 to slide upward. When the driving rod 12 moves to the leftmost end of the conveyor belt 6, the placement frame 19 moves to the highest point. The grain in the placement frame 19 falls onto the vibrating screen body 2 through the discharge port 20 and the connecting port 18. The grain falls onto the vibrating screen body 2 through the opening on the blocking frame 8 for screening. When the grain on the placement frame 19 slides out completely, the conveyor belt 6 drives the driving rod 12 to move to the right. At this time, the placement frame 19 slides downward. When the driving rod 12 moves to the rightmost end of the conveyor belt 6, the placement frame 19 is at the lowest point. At this time, the operator shovels the grain and puts it into the placement frame 19. This process is repeated to achieve grain screening.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
