Sand mixer mixing device capable of increasing mixing contact surface and achieving uniform and automatic discharging

Abstract

The invention provides a sand mixer mixing device capable of increasing the mixing contact area and achieving uniform and automatic discharging, and relates to the technical field of sand mixers. The sand mixer mixing device capable of increasing the mixing contact surface and achieving uniform and automatic discharging comprises a shell; a discharging opening is formed in the bottom of the shell; a feeding hopper is fixedly installed at the position of a feeding opening; a pressing block is arranged in the discharging opening in a sliding mode; and the two sides of the bottom of the pressing block are fixedly connected with blocking blocks. According to the sand mixer mixing device capable of increasing the mixing contact area and achieving uniform and automatic discharging, by arranging a plurality of mixing and stirring structures and driving the mixing and stirring structures to be extended for use through rotating centrifugal force, the stirring contact area can be effectively increased, and the machining efficiency is improved; and as structures such as a push rod, the pressing block and the blocking blocks are arranged, automatic and uniform discharging can be achieved when an external motor works, and when the motor stops working, the pressing block can automatically reset to drive the blocking blocks to move upwards to block the discharging opening.

Description

technical field [0001] The invention relates to the technical field of sand mixers, in particular to a sand mixer mixing device capable of increasing the mixing contact surface and uniformly and automatically discharging materials. Background technique [0002] The sand mixer is a foundry equipment used to mix molding sand or core sand. The sand mixer generally has the following functions: mix old sand, new sand, molding sand binder and auxiliary materials evenly, and generate corresponding friction and shear forces through the sand grains. , so as to produce rubbing, mixing, crushing and other functions, but the current mixing device of the sand mixer still has the following deficiencies in use: 1. The current common mixing device of the sand mixer only has a single or two or three mixing devices in actual use. Shaft, so that the sand inside the device is inefficient and ineffective during actual mixing and stirring; Second, when the current common sand mixer mixing device ...

The current common mixing device of the sand mixer only has a single or two or three mixing devices in actual use. Shaft, so that the sand inside the device is inefficient and ineffective during actual mixing and stirring; Second, when the current common sand mixer mixing device is actually used, most of them are stirred or mixed with the internal sand and then manually discharged. material, this way of discharging is very inconvenient and inefficient
