Detailed Description

Example (b):

as shown in fig. 1-4, a sand and stone screening machine comprises a screening machine body 1, a dust cover 2 positioned above the screening machine body 1, and a discharge plate 3 positioned below the screening machine body 1, wherein a feed hopper 4 is arranged on the top surface of the dust cover 2, and the bottom surface of the dust cover 2 is detachably connected to the screening machine body 1.

The screening machine body 1 is a screening machine which does not have a dustproof function in the prior art; establish through the cover of dust cover 2 and can shelter from the ascending dust of 1 feeding direction of screening machine body, reduce the outflow volume of dust, lead through play flitch 3 grit after to the screening, accomplish the ejection of compact.

Although the dust-proof mode reduces the overflow of dust, the dust-proof mode only acts on the feeding direction. It is known that the upper and lower sides of the screen body 1 are communicated with each other, and the dust cover 2 covers the upper side of the screen body 1, so that dust can escape from the lower side of the screen body 1 to the outside, and the structure of the dust cover 2 is further improved.

Specifically, the dust cover 2 is further provided with a spraying piece 5, namely, the spraying piece 5 is used for spraying and preventing dust, so that dust is gathered into a cluster and is difficult to float in the air, and dust pollution is effectively reduced.

In one possible implementation, the spray member 5 is provided with at least two groups, one of which is located on the top surface of the dust cap 2 and the spray direction is towards the feed hopper 4, and the remaining groups are located on the side surfaces of the dust cap 2 and spray into the dust cap 2; therefore, the covering surface of the spray piece 5 is increased, when the feeding device feeds materials, ores fall on the feed hopper 4 and collide with each other, and certain dust is generated, so that a group of spray pieces 5 are arranged on the top surface of the dust cover 2.
