step three: the total power can be closed after the material screening finishes, and the gag lever post 67 is pulled out upwards, and gag lever post 67 upwards breaks away from the inner chamber of spacing groove 65 and makes first spring 68 compress, holds handle 63 and outwards stimulates door body 62 with the help of external force, makes door body 62 drive fixture block 64 and breaks away from draw-in groove 66 inner chamber, and third discharge gate 61 at this moment is open state, and the coarse aggregate that is located screen cloth 4 upper surface can flow outward via third discharge gate 61 and collect.
Above-mentioned grit screening machine examination is used at building aggregate screening job site, the device can be when equipment continuously runs the collection that realizes the material, in the time of the whole operation of equipment, the screening speed of material has been guaranteed, the productivity of enterprise has been improved about 34%, be convenient for more realize opening and shutting of the door body 62 through coarse aggregate unloading mechanism 6, thereby be convenient for collect the clearance with the coarse aggregate of screening more, can realize the buffering many times of 1 vibrations of box through damper 7, the stability of box 1 has been guaranteed when guaranteeing 1 vibrations of box.
