Embodiment Construction

[0042] The invention discloses a planar vibrating sample pulverizer, which can improve the service life of a driving device and avoid failure problems of spring stiffness.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] see figure 1 , figure 1 Schematic diagram of the structure of the planar vibrating sample pulverizer provided by the embodiment of the present invention.

[0045] The planar vibrating sample preparation pulverizer provided by the present invention includes: a frame 1, a driving de...

Abstract

The invention discloses a planar vibration sample preparation crusher, comprising a rack (1), a driving device arranged on the rack (1), an eccentric shaft (10) arranged on the rack (1) by virtue of a bearing, a vibration disk (9) connected with the eccentric shaft (10) and a crushing device fixed on the vibration disk (9) by virtue of a compacting device (4), wherein the driving device is connected with the eccentric shaft by virtue of a transmission device. In the invention, the driving device is separated from the vibration disk and is independently fixed, the driving device does not vibrate any longer, the working conditions of the driving device are improved, the driving device is connected with a flange plate and a machine case, the strength is not required to be enhanced, the requirement to the driving device is reduced, and the service life of the driving device is greatly prolonged. The vibration disk is rigidly connected with the rack by virtue of the eccentric shaft insteadof a spring, no combination of rigidity of the spring is required during a mounting process, the problem that the rigidity of the spring is invalid can not be caused, the assembling difficulty is reduced, and the fault rate is also reduced.

Description

technical field [0001] The invention relates to the technical field of sample preparation pulverizers, in particular to a planar vibrating sample preparation pulverizer. Background technique [0002] The current sample pulverizer basically uses the motor to drive the eccentric block to move at high speed to generate an exciting force, which drives the pulverizing rod and pulverizing ring in the pulverizing bowl to collide at high speed and crush the granular material, so as to achieve the purpose of pulverization. [0003] The eccentric block of the current sample pulverizer is directly installed on the output shaft of the motor, and the motor is directly installed on the lower part of the vibrating body. When the motor is working, its output shaft must bear radial force, axial force and torque, and it must bear three kinds of loads in total. , causing the motor to be easily damaged, and the maintenance frequency is high. The vibrating body is installed on the frame through...
