As shown in the figure, a vibrating screen machine that dustproof effect is good is provided, including frame 1, the mid-mounting of frame 1 bottom surface has control valve 2, the both sides of frame 1 top surface respectively fixedly connected with upwards stretch out slide bar 3, slide bar 3's middle part activity has cup jointed sliding ring 4, and sliding ring 4's outside fixedly connected with screen cloth 5, the dustproof apron 9 of fixedly connected with on frame 1, spout 6 has been seted up in the front of dustproof apron 9, elastic adhesive tape 7 is pasted at the middle part of spout 6, the joint has the scraper 8 that runs through the inside and outside both sides of dustproof apron 9 on the spout 6, the locating lever 10 that upwards stretches out of right side fixedly connected with of frame 1, the top of locating lever 10 is connected with transmission 11, and motor 12 is installed on transmission 11's right side. The dust cover plate 9 on the outer side can reduce the situation that dust splashes everywhere, the dust can be gathered below the machine base 1, and after the control valve 2 is unscrewed, the dust and the screened materials can be discharged outwards. Simultaneously, when the sieving machine used, probably there was the material to appear blocking or the condition of bonding on the screen cloth 5, the scraper 8 of activity can be convenient for realize clean operation to screen cloth 5 self.

Fig. 3 is the utility model discloses a structural schematic is overlooked to dustproof cover plate, dustproof cover plate 9 is including plate body 91, and the expansion plate 92 has been cup jointed in the activity respectively in the both sides of plate body 91 top surface, and one side fixedly connected with magnetic stripe 93 that both sides expansion plate 92 is close to the middle part. The opening of expansion plate 92 can be convenient for put in the material to screen cloth 5 on to the closure of expansion plate 92 can prevent that the dust from outwards flying out, and after expansion plate 92 closed, the magnetic stripe 93 of both sides mutual absorption can guarantee closed compactness between the two.

In this embodiment, the transmission device 11 includes a protection frame 111, a turntable 112 is installed above an inner cavity of the protection frame 111, one end of a movable rod 113 is hinged to a side surface of the turntable 112, a telescopic rod 114 is hinged to the other end of the movable rod 113, the telescopic rod 114 penetrates through the inner side and the outer side of the protection frame 111, and the bottom end of the telescopic rod 114 and the side surface of the screen 5 are connected with each other. The output shaft of the motor 12 is sleeved in the middle of the turntable 112, the motor 12 can drive the turntable 112 to synchronously rotate, when the turntable 112 rotates, the movable rod 113 can move up and down, acting force which moves up and down can be transmitted to the screen 5 through the telescopic rod 114, and the device is a main power source which can realize screening operation on materials.

As shown in figure 2, the periphery of the bottom surface of the base 1 is fixedly connected with four supporting legs respectively, and the bottom surfaces of the four supporting legs are on the same horizontal plane. Through adopting the design at same horizontal plane supporting leg respectively around the device bottom surface for the supporting leg can not only provide the effort that supports for the device, still = can ensure the good stability of device self.

It should be noted that the bottom surface of the base 1 is downwardly convex, and the control valve 2 is installed at the lowest position of the bottom surface of the base 1. When the operation of shaking the sieve goes on, the material after the screening can gather in the below of frame 1, through the design with frame 1 self adoption downward protrusion form for the material can outwards be discharged under the action of gravity, reaches and avoids remaining effect in frame 1.

It should be noted that a strip-shaped groove is formed on the right side of the dust-proof cover plate 9, and the telescopic rod 114 passes through the strip-shaped groove and extends into the dust-proof cover plate 9. The acting force of the movement of the screen 5 is provided by the external transmission device 11 and the motor 12, and the design of forming a strip-shaped groove on the side surface of the dustproof cover plate 9 leaves space for the movement of the telescopic rod 114, so that the device is a feasible important structural support.
