Feeding cavity device and sand making machine

Abstract

The invention relates to the field of engineering machinery, and discloses a feeding cavity device and a sand making machine. The feeding cavity device (100) comprises a feeding cavity main body (110), a guiding mechanism (120) and an adjusting mechanism (130), the guiding mechanism comprises a fixedly-arranged sliding way (121), the feeding cavity main body comprises multiple door plates (111) bywhich a cavity closed in the circumferential direction and opened in upper and lower ends can be defined, each door plate comprises a first end located at the lower end of the cavity and a second endlocated at the upper end of the cavity, each second end is provided with a sliding part (111a) driven by the adjusting mechanism, the first ends are arranged to enable the door plates to rotate relative to one another, therefore, the sliding parts are moved along the sliding way to change the size of the opening in the upper end of the cavity, and the size of the opening in the lower end of the cavity is kept unchanged. When the feeding cavity device is in use, the sliding parts are moved along the sliding way to change the size of the opening in the upper end of the cavity, and therefore theamount of materials fed by the feeding cavity device to an impeller assembly can be conveniently adjusted and controlled.

Description

technical field [0001] The invention relates to engineering machinery, in particular to a feeding chamber device and 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 intensification of government environmental protection measures, natural sand resources are becoming increasingly depleted, and machine-made sand and gravel have become the mainstream of the sand and gravel aggregate industry. At present, sand and gravel can be prepared by a vertical shaft impact crusher, which mainly includes a feeding device, a hopper, an impeller assembly, a crushing chamber and other structures. The material is supplied from the feeding device to the hopper, and falls from the hopper into the impeller assembly and Kinetic energy is obtained through the rotation of the impeller assembly. When the material with certain kinetic energy moves outward f...
