Drawings

Fig. 1 is the structure schematic diagram of the molding sand impurity removing device provided by the utility model.

Detailed Description

The following describes a sand mold cleaning device in detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

Example one

The utility model provides a molding sand edulcoration device, its structure is as shown in figure 1. The molding sand impurity removing device comprises a sand box 1, wherein a crushing mechanism, a swinging basket net 3 and an impurity removing transmission belt 4 are arranged in the sand box 1; the crushing mechanism comprises a rotating shaft 21, a crushing rod 22 is fixedly connected to the outer shaft surface of the lower end of the rotating shaft 21, and the crushing rod 22 extends into the sand box 1; the swinging basket net 3 is positioned below the crushing mechanism, and molding sand in the swinging basket net 3 is subjected to swinging filtration, so that the blockage of the conventional fixed filter screen due to the accumulation of the molding sand can be avoided; the swinging basket net 3 is supported by a transverse shaft 31, two ends of the transverse shaft 31 are respectively connected with the side wall of the sand box 1 through bearings 32, and one end of the transverse shaft 31 is electrically connected with a second motor 32 through a transmission mechanism; the two ends of the inner side of the impurity removing conveyor belt 4 are respectively provided with a roller 41 and a magnetic roller 42, and the conveying direction is that the roller 41 conveys the magnetic roller 42.

Specifically, with continued reference to fig. 1, the crushing mechanism further includes a support block 23, a first rotating disk 24 and a second rotating disk 25; the supporting block 23 is detachably mounted at the top end of the sand box 1, the rotating shaft 21 is rotatably mounted on the supporting block 23, the first rotating disc 24 is fixedly connected with the rotating shaft 21, the first rotating disc 24 is connected with the second rotating disc 25 through a conveying belt 26, and the second rotating disc 25 is connected with a rotating shaft of a first motor 27.
