Casting machinery sand mixing equipment with high forming rate

Abstract

The invention discloses casting machinery sand mixing equipment with a high forming rate, and relates to the technical field of sand mixing. The casting machinery sand mixing equipment comprises a U-shaped support, a mixing tank is rotationally matched in the U-shaped support, one end of the mixing tank is connected with a screening mechanism, and a discharging assembly is arranged on the side portion of the mixing tank; and the screening mechanism comprises a connecting pipe connected to one end of the mixing tank, a conveying assembly arranged on the U-shaped support and a screening assembly arranged at the end, away from the mixing tank, of the connecting pipe. By arranging the screening assembly arranged at the end, away from the mixing tank, of the connecting pipe, large stone sand in stone sand can be screened conveniently, the stone sand is made to be uniform in size, the uniformity and forming probability of sand mixing are further improved, the multiple lifting strips are arranged on the inner wall of the mixing tank in the circumferential direction, the vertical section of each lifting strip is in an isosceles triangle shape, the mixed sand can conveniently roll for a period of time along with the mixing tank and can be lifted out and reciprocated by the lifting strip, so that the movement modes of the mixed sand in the mixing tank are increased, and the uniformity and the forming probability of the mixed sand are further improved.

Description

technical field [0001] The invention belongs to the technical field of sand mixing, in particular to a casting machine sand mixing equipment with high forming rate. Background technique [0002] Sand mixing equipment is a machine that makes the components in the molding sand evenly mixed. It is usually necessary to add a binder during mixing. Using sand mixing equipment can effectively coat the binder on the surface of the sand grains. Sand mixers are usually used in the casting production process Mixing of raw materials. [0003] The existing sand mixer has a single function, and can only simply mix the stone and sand, and cannot sieve the stone and sand, and cannot screen out larger particles, making the sand mixing uneven, and mostly the binder is mixed at one time. Pour it together with stone sand for mixing, it is easy to cause uneven mixing and poor sand mixing quality. Contents of the invention [0004] The purpose of the present invention is to provide a casting ...
