Host machine feeding adjusting mechanism for sand making machine and sand making device

Abstract

The invention provides a host machine feeding adjusting mechanism for a sand making machine and the sand making device. The sand making machine comprises at least two host machines and can send out current signals. The host machine feeding adjusting mechanism for the sand making machine comprises a buffer box, a material distributing plate and a material distributing controller, wherein a gravel feeding port is formed in the top of the buffer box; the bottom of the buffer tank communicates with the host machines through articulated chutes respectively; the material distributing plate is vertically mounted in the buffer box and can swing in a circumferential direction and adjust the amount of sands flowing into each host machine from the corresponding articulated chute; and the material distributing controller is configured to obtain a current difference signal of the two host machines and sent outa material distributing plate swing driving signal in response to the current difference signal. By additionally arranging the material distributing plate capable of adjusting a direction of the sands entering the host machines in the buffer box, a feeding direction can be automatically adjusted according to the load condition and the current of the host machines, the situation that feeding of multiple host machines is unbalanced, and resources are wasted is avoided, the situation that blockage is caused by excessive feeding of the host machines, and sand blockage is manually treated can further be avoided, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of sand making, and in particular relates to a main machine material feeding adjustment mechanism and a sand making device of a sand making machine. Background technique [0002] Sand and gravel aggregate is the most widely used material in the field of construction. With the depletion of natural sand and gravel and the strengthening of government environmental protection, machine-made sand and gravel have become the mainstream of the sand and gravel aggregate industry. Sand making machines are widely used in the preparation of machine-made sand and gravel. In order to ensure the efficiency of sand making, two main machines are generally installed, and the material enters the main machine through the slide pipe from the buffer box. The buffer box slides the sand and gravel into the main machine through the chute, and the material can not be adjusted, which leads to the unbalanced sand and gravel in the two m...
