Grinding wheel device of smashing machine

Abstract

The invention provides a grinding wheel device of a smashing machine. The grinding wheel device comprises a smashing cavity body, a grinding wheel support and a grinding device. The grinding wheel support is in a disc shape and is provided with an upper grinding disc and a lower grinding disc, the middle of the grinding wheel support is provided with a center end hub which is used for connecting and fixing the upper grinding disc and the lower grinding disc, the circle center of the center end hub is hollow and penetrates through the circle centers of the upper grinding disc and the lower grinding disc to form a transmission shaft hole, the grinding wheel support is installed inside the smashing cavity through the transmission shaft hole. The grinding device is arranged between the upper grinding disc and the lower grinding disc and comprises grinding wheel grooves, grinding wheels, grinding rings and inner grinding rings; the multiple grinding wheels are mounted in the grinding wheelgrooves through grinding wheel mounting devices; the grinding rings are arranged on the inner side of the smashing cavity in a surrounding manner corresponding to the positions of the grinding wheelsand are matched with the grinding wheels; and the inner grinding rings are installed and fixed in the grinding wheel grooves correspondingly, are positioned in the middle of the center end hub and thegrinding wheels, are in an arc shape in the direction facing the grinding wheels and are matched with the grinding wheels.

Description

Technical field [0001] The invention relates to a grinding wheel device of a pulverizer. Background technique [0002] The crusher is a machine that crushes large-size solid materials to the required size; the crusher is composed of devices such as coarse crushing, fine crushing, and pneumatic conveying. It achieves the purpose of crushing materials in the form of high-speed impact; the grinding wheel device of the existing crusher passes A plurality of grinding wheels are installed in the grinding wheel groove of the grinding wheel support, the motor drives the transmission shaft to drive the grinding wheel support to rotate, and further drives the grinding wheel and the grinding ring installed on the outside of the grinding wheel support to squeeze and rub against each other to achieve the purpose of crushing the grinding material. [0003] The grinding wheel is installed in the grinding wheel groove of the grinding wheel support through a pin shaft. During rotation, it presses a...

Problems solved by technology

[0003] The grinding wheel is installed in the grinding wheel groove of the grinding wheel bracket through the pin shaft. During the rotation, it squeezes and rubs against the grinding ring outside the grinding wheel bracket. The reaction force received is transmitted to the grinding wheel bracket, causing the grinding wheel bracket to crack until it breaks, and often needs to be replaced.
