Efficient quantitative sand mixing equipment capable of avoiding insufficient sand mixing

Abstract

The invention relates to the technical field of precision casting, and discloses efficient quantitative sand mixing equipment capable of avoiding insufficient sand mixing. The efficient quantitative sand mixing equipment comprises a grinding bin, a grinding wheel is movably connected to the interior of the grinding bin, a feeding opening is formed in the top of the grinding bin, a belt is movably connected to the side face of the grinding wheel, a quantitative mechanism is arranged inside the grinding bin, a first inclined plate is arranged at the bottom of the grinding bin, a screening bin is arranged at the bottom of the grinding bin, and a rotating plate is movably connected to the interior of the screening bin. According to the efficient quantitative sand mixing equipment capable of avoiding insufficient sand mixing, through cooperation usage of the quantitative mechanism and a stirring rod, the proportion of clay and burnt-on sand can quantitatively match before the clay and the burnt-on sand are mixed, then screening and stirring are conducted, high efficiency is achieved, the mixing quality is guaranteed, casting smoothness is improved, the quality of the surface of a casting piece is improved, and it is guaranteed that benefits of processing enterprises are not affected to a certain extent.

Description

Technical field[0001]The present invention relates to the field of precision casting techniques, in particular a highly efficient quantitative sand-absorbing equipment that avoids insufficient sand.Background technique[0002]Casting is a metal thermal processing process, which is cast in a cast cavity that is adapted to the shape of the part shape to obtain a part or blank after obtaining a liquid metal into a cast cavity that is compatible with the shape of the part. The method of obtaining the part or blank; the sand is used as a focus Equipment, is a key factor in control sand quality, cost, and it is difficult to control the ratio of clay and viscopaschable when mixing sandstone and sand, resulting in high quality of the mixture, affecting the fluency of casting. It also affects the surface quality of the foundry, resulting in a decrease in the qualification rate of casting parts to a certain extent, and the impact of the interests of processing enterprises.Inventive content[0003...
