I. Description of the electric vibrating screen machine Scope of application: This machine is suitable for screening analysis of materials in the laboratory of highway, construction, geological metallurgical scientific research, etc., each time it is turned on for 5 minutes, it is convenient and simple to complete the grading work. Technical specifications 1, sieve diameter: 200mm2, sieve stack height: 400mm3, screen seat amplitude: 8mm4, sieve shake times: 221 times / minute 5, shock times: 147 times / minute 6, radius of gyration: 12.5mm7, power supply 380V power : 0.37 kW 8. Dimensions: 600x400x8809, total weight: 130 kg III. General drawing and main structure description The structure of the machine is shown in the figure. The main organic seat, upper cover, slewing mechanism, vibrating mechanism and clamping mechanism are The set of sieves is composed of the main structure as follows. 1. The slewing mechanism motor (1A) and the clutch body (146A) rotating bushing (145A) get the gear (135A) to drive the small helical gear (141A) on the gear shaft (137A) to rotate through the gear (152A). The gear drives the large helical gear (97A) to rotate the hollow main eccentric shaft (74A) to which the key is connected, thereby driving the three sub-eccentric shafts (15A) on the upper cover (3A) to be rotated by 120 degrees. Make the entire movable frame shake with a radius equal to the eccentricity of the perfect circle. 2. When the movable frame is shaken by the positive circular plane, the upper eccentric cam (05A) on the striking shaft is driven by the main eccentric upper cover (70A) fixed by the screw to drive the striking shaft (109A). Rotating, while the gear is driven by the gear (164A) on the (137A) through the gear (157A) (159A) to drive the lower end cam (107A) of the gear shaft 100 to rotate slowly, and the cams of the upper and lower end faces rotate in the same direction to generate axial displacement. Top up until the upper and lower plane cam notches fall down and get a vibrating motion. The role of the compression spring (78A) is to enhance the impact force. 3. Tightening the structure Rotating and tightening bolts (55A) can make the retracting nut (54A) move in a high axial direction, so that the screen cap fixing ejector (47A) can be extended outwards, so as to top the screen cover and reach the fixed screen cover. .
