[0031] The moving mechanism 13 includes a support column 131, which is fixedly connected to the bottom of the box body 1, and a sliding wheel 132 is installed at the bottom of the support column 131; by setting the moving mechanism 13, when the screening device needs to be moved and transported, the box body 1 is pushed, so that the sliding wheel 132 can drive the box body 1 to move horizontally through the support column 131, that is, drive the sorting screen 4 to move horizontally, thereby facilitating the adjustment of the working position of the screening device.

[0032] The working principle of a highway maintenance gravel multi-stage screening device provided by the utility model is as follows:

[0033] Step 1: First, when the sorting screen 4 is worn out after long-term use and needs to be replaced, pull the clamping column 5 so that the clamping column 5 can be removed from the inside of the sorting screen 4.

When the gravel sorting produces large dust, the dust suction pump 121 is started, so that the dust suction pump 121 can absorb the floating dust inside the box body 1 through the dust suction pipe 122, and then transport it to the dust collecting box 123 for storage, thereby avoiding the problem of air pollution caused by a large amount of dust during gravel sorting. When the screening device needs to be moved and transported, the box body 1 is pushed, so that the sliding wheel 132 can drive the box body 1 to move horizontally through the support column 131, that is, drive the sorting screen 4 to move horizontally, thereby facilitating the adjustment of the working position of the screening device.

[0035] Compared with the related art, the highway maintenance gravel multi-stage screening device provided by the utility model has the following beneficial effects:

[0036] By setting the clamping column 5, when the sorting screen 4 is used for a long time and is seriously worn and needs to be replaced, the clamping column 5 is pulled to move the clamping column 5 out from the inside of the sorting screen 4. At this time, the sorting screen 4 is pulled to move the sorting screen 4 out from the inside of the No. 1 support frame 3, that is, out from the inside of the box body 1, thereby achieving the effect of replacing the sorting screen 4, thereby bringing convenience to the maintenance of the screening device.
