The rotation of the rotating shaft 31 drives the cam 32 to rotate, and then drives the connecting shaft 33 to rotate. The rotation of the connecting shaft 33 causes the lower end of the connecting rod 34 to rotate around the central axis of the rotating shaft 31. When the lower end of the connecting rod 34 rotates upward, the upper end of the connecting rod 34 pushes the driving column 36 to slide upward inside the slide cylinder 35.

The lower end of the limiting column 44 is fixedly connected to support plate 2. , the support plate 1 is vertically matched with the support plate 2, and the driving handle 41 is rotated in turn. The rotation of the driving handle 41 drives the vertically adjacent screw rods 42 to rotate. The screw rods 42 move upward under the action of the vertically adjacent adjustment cylinders 43. The upward movement of the screw rods 42 drives the vertically adjacent support plate 2 to move upward, thereby realizing the vertical spacing adjustment between the support plate 2 and the vertically adjacent support plate 1. The downward movement of the screening bin 2 drives the limit column 44 to move downward. When the support plate 1 contacts the support plate 2, the screening bin 2 stops moving downward, thereby limiting the amplitude and frequency of the screening bin 2.

[0030] The working principle of the beer production malt screening device provided by the utility model is as follows: when working, the personnel first stably move the support platform 1 and the screening bin 2 and other mechanisms to the designated working area through the moving wheel 14, and then the personnel turn the driving handle 41 in sequence according to the malt vibration screening needs, and the rotation of the driving handle 41 drives the vertically adjacent screw rods 42 to rotate, and the screw rods 42 move upward under the action of the vertically adjacent adjusting cylinders 43, and the upward movement of the screw rods 42 drives the vertically adjacent support plate 2 to move upward, thereby realizing the support plate 2 and the vertically adjacent support plate 1. The vertical spacing adjustment is performed. When the support plate 2 and the vertically adjacent support plate 1 reach the required spacing, the personnel stops rotating the driving handle 41, and then the personnel add the malt to be screened into the screening bin 2 through the feed port. At the same time, the personnel realizes the operation of the motor 7 by controlling the switch 15. The output shaft of the motor 7 rotates to drive the driving wheel 6 to rotate. The driving wheel 6 drives the driven wheel 5 to rotate through the transmission belt, thereby driving the rotating shaft 31 on the right to rotate. The rotation of the rotating shaft 31 drives the cam 32 to rotate, thereby driving the connecting shaft 33 to rotate. The rotation of the connecting shaft 33 causes the lower end of the connecting rod 34 to rotate. The end rotates around the central axis of the rotating shaft 31. When the lower end of the connecting rod 34 rotates upward, the upper end of the connecting rod 34 pushes the driving column 36 to slide upward inside the sliding cylinder 35. The driving column 36 contacts the pillar and pushes the pillar to move upward. At the same time, the spring 38 is elastically stretched, and the telescopic ends of the telescopic columns 37 are stretched, thereby realizing the upward movement of the screening bin 2. At the same time, the sliders 12 slide upward inside the corresponding slide grooves 11 to provide a guide for the movement of the screening bin 2. When the lower end of the connecting rod 34 rotates downward, the driving column 36 stops supporting the pillar, and under the gravity, the driving column 36 stops supporting the pillar. Under the action of the elastic force of the spring 38, the screening bin 2 moves downward, the pillar follows it and the telescopic end of the telescopic column 37 contracts. The screening bin 2 moves downward and drives the limit column 44 to move downward. When the support plate 1 contacts the support plate 2, the screening bin 2 stops moving downward, thereby limiting the amplitude and frequency of the screening bin 2. As the lower end of the connecting rod 34 makes a circular motion around the central axis of the rotating shaft 31, the screening bin 2 and the screening plate 8 move back and forth, thereby screening the malt. Impurities are removed through the waste port and the screened malt is removed through the discharge port.
