a lost foam casting dust-free sand box comprises a sand box and two suction assemblies, wherein the two suction assemblies are respectively arranged on the outer sides of the upper parts of two long edges of the sand box; the suction assembly mainly comprises a dust collection outer shell and a dust collection inner shell, wherein a main dust collection pipe is fixed at the end part of the dust collection outer shell close to the sand box, and the inner dust collection shell is fixedly covered on the inner side of the dust collection outer shell;

a suction channel is preset between the dust collection outer shell and the dust collection inner shell and is communicated with the dust collection main pipe; the dust collection inner shell is provided with a plurality of dust collection holes distributed at equal intervals, when sand is required to be filled in the sand box, the two suction components lean against the long side wall of the sand box in a rotating and inclining mode through the bearing, at the moment, the two dust collection outer shells are distributed in a herringbone mode, the two dust collection main pipes are communicated with an external dust collector suction pipe, and dust rising in the feeding process is thoroughly sucked into the dust collection main pipes through the dust collection holes in the dust collection inner shell, so that a stable dust collection effect is achieved.

In a preferred embodiment of the present invention, bearings are fixedly sleeved at both ends of the main dust suction pipe, and outer rings of both the bearings are fixed to the long side walls of the sand box.

In a preferred embodiment of the present invention, one end of the main dust suction pipe is a closed structure.

In a preferred embodiment of the present invention, the dust suction outer casing and the dust suction inner casing are detachably connected by screws.

In a preferred embodiment of the present invention, a sealing rubber pad is adhered to each of the attaching surfaces between the dust suction outer casing and the dust suction inner casing.

Compared with the prior art, the utility model has the following beneficial effects:

when sand needs to be filled into the sand box, the two suction components lean against the side wall of the long edge of the sand box in a rotating and inclining mode through the bearing, the two dust suction outer shells are distributed in a herringbone mode, the two main dust suction pipes are communicated with the suction pipe of an external dust collector, and dust generated in the feeding process is thoroughly sucked into the main dust suction pipes through the dust suction holes in the inner dust suction shell, so that a stable dust suction effect is achieved.

Because the suction assembly consists of the dust collection outer shell and the dust collection inner shell, even if the dust collection hole is blocked in the later period, the dust collection inner shell can be detached for cleaning, and the practicability is higher.

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
