In use, the air supply box is used for conveying flowing air flow to the direction of the vibrating screen 100 to blow up the light materials on the vibrating screen 100, so that the light materials float upwards, and the air baffle 200 on the vibrating screen 100 pushes the floating objects to move towards the rear end of the vibrating screen 100, so that the unqualified light materials and impurities are separated from the materials with heavier mass. The front end of shaker 100 may be provided with a front end take-up device for collecting heavier materials. The rear end of the vibrating screen 100 can be provided with a rear end receiving device and a suction device, the suction device can be used for sucking away impurities such as dust and extremely light objects, the materials and impurities with lighter weight are transported to the rear end along with the vibration of the vibrating screen 100 under the action of gravity and wind, and are collected by the rear end receiving device at the rear end of the vibrating screen 100.
As shown in fig. 1, the blow box includes a housing 10, and a first partition 20 located in the housing 10. Wherein a chamber is formed in the housing 10 for the flow of air. The upper part of the shell 10 is an opening structure as an air outlet, and the air outlet is communicated with the accommodating cavity.
At least one first partition plate 20 is arranged in the cavity, and the first partition plate 20 is used for dividing the cavity into at least two chambers.
In this embodiment, a first partition 20 is disposed in the cavity, and the cavity is correspondingly divided into two chambers, namely a first chamber 91 and a second chamber 92. Both the first chamber 91 and the second chamber 92 communicate with the air outlet.
In the embodiment, the first chamber 91 and the second chamber 92 are respectively connected with a separate air inlet 40, wherein the air inlet 40 is used for communicating with the blower. Therefore, in operation, the air inlet 40 supplies flowing air flow into the corresponding chamber, and after the flowing air flow enters the corresponding chamber, the flowing air flow flows towards the air outlet under the action of the shell 10 and the first partition plate 20, and then is conveyed outwards from the air outlet.
