Coal pulverizer with function of reminding over-low rotating speed of motor

Abstract

The invention discloses a coal pulverizer with a function of reminding over-low rotating speed of a motor. The coal pulverizer comprises a base, a supporting column is fixedly arranged at the upper end of the base, and a power shell is fixedly arranged at the upper end of the supporting column. According to the coal pulverizer, when the rotating speed of the motor is decreased in the device and the rotating speed of a power friction wheel is decreased, a sliding block is made to move rightwards, and the sliding block moving rightwards drives a friction wheel through a fifth transmission shaftto be in friction connection with the position, with the small radius, of the power friction wheel, so that a smashing wheel is kept at the normal rotating speed all the time, and a sliding support ismade to move leftwards; and when the rotating speed is too low, the sliding support moving leftwards drives a fifth bevel gear and a sixth bevel gear to be in engaged connection through an eighth transmission shaft, so that a second transmission shaft has power to enable sounding metal to sound to remind workers that the motor speed is too low, the problem of low efficiency caused by reduction ofthe motor speed can be relieved within a certain range, the workers can be reminded when the motor speed is too low, and the working reliability of the pulverizer is guaranteed.

Description

technical field [0001] The invention relates to the technical field of coal pulverization, in particular to a coal pulverizer with a motor speed warning function. Background technique [0002] The coal crusher is called coal crusher for short, and it is one of the commonly used equipment in the production line of crushing coal and crushing coal gangue. Most of the current coal pulverizers use motors as the power source for their work, but because of the particularity of the motors, the consumption of lubricants or many other factors will cause the motor speed to decrease, which will eventually lead to a reduction in the speed of the pulverizing wheel, which cannot be used for coal crushing. Carrying out pulverization, when artificial discovery is late, also can cause waste a large amount of time, and can't guarantee the efficiency of coal pulverization, a kind of device that can solve the above-mentioned problem that the present invention clarifies.
