Abstract

A flexible connection feeding mechanism of a coal breaker relates to a flexible connection feeding mechanism between a feed port of the coal breaker and a coal dropping pipe of a coal screening machine. Mainly be to establish the canvas buffering effect outside the inlet pipe at present poor, fragile problem and design. The coal crusher comprises an inner shell, wherein the upper end of the inner shell is connected with a coal dropping pipe of a coal screening machine through a bolt, and the lower end of the inner shell is connected with a feed inlet of a coal crusher through a flange; an outer shell is arranged outside the inner shell, the lower end of the outer shell is welded on the coal crusher, and a distance is reserved between the top end of the outer shell and the bottom end of a coal dropping pipe of the coal screening machine; an annular cushion pad is clamped between the inner shell and the outer shell, a cylindrical protective cover is arranged outside the outer shell, the upper end of the protective cover is connected to the lower end of a coal dropping pipe of the coal screening machine through a bolt, and the lower end of the protective cover is connected to the coal breaker through a bolt. The advantage is that buffering effect is good, and the protection casing is not fragile.

Description

Flexible connection feeding mechanism of coal crusher

The technical field is as follows:

the utility model relates to a flexible connection feeding mechanism between a feeding hole of a coal breaker and a coal dropping pipe of a coal screening machine.

Background art:

a coal screening machine is arranged above the coal breaker, a feeding pipe is connected between a coal dropping pipe of the coal screening machine and a feeding hole of the coal screening machine, and the coal screening machine shakes due to large vibration of the coal breaker during working, so that the coal screening machine is easy to damage; therefore, a flexible connection mechanism is arranged at the feeding pipe to buffer the vibration force. At present, a circle of canvas is arranged outside a feeding pipe, the upper end of the canvas is fixed on a coal dropping pipe of a coal screening machine, and the lower end of the canvas is fixed on a feeding hole of a coal breaker; however, the canvas has poor buffering effect and is easy to damage, dust leakage is caused after the canvas is damaged, and the environment is polluted.

The utility model content is as follows:

the utility model aims to solve the technical problem of providing a soft connection feeding mechanism of a coal breaker, which has a good buffering effect and is not easy to leak dust.

The above object is achieved by: the coal crusher comprises an inner shell, wherein the upper end of the inner shell is connected with a coal dropping pipe of a coal screening machine through a bolt, and the lower end of the inner shell is connected with a feed inlet of a coal crusher through a flange; an outer shell is arranged outside the inner shell, the lower end of the outer shell is welded on the coal crusher, and a distance is reserved between the top end of the outer shell and the bottom end of a coal dropping pipe of the coal screening machine; an annular buffer cushion made of a pearl wool plate is clamped between the inner shell and the outer shell, namely the inner surface of the buffer cushion is contacted with the outer wall of the inner shell, and the outer surface of the buffer cushion is contacted with the inner wall of the outer shell; the cylindrical protective cover is arranged outside the outer shell and is made of aviation rubber, the upper end of the protective cover is connected to the lower end of a coal dropping pipe of the coal screening machine through a bolt, and the lower end of the protective cover is connected to the coal breaker through a bolt.

The utility model has the advantages that: the buffer cushion is clamped between the inner shell and the outer shell, so that the buffer effect is good; because the protective cover is arranged outside the outer shell, the protective cover made of aviation rubber is not easy to damage, and dust is not easy to leak.

Description of the drawings:

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is an enlarged schematic view of a portion a of fig. 1.

The specific implementation mode is as follows:

the utility model is further illustrated with reference to fig. 1 and 2;

the coal crusher comprises an inner shell 1, wherein the upper end of the inner shell is connected with a coal dropping pipe 2 of a coal screening machine through a bolt, and the lower end of the inner shell is connected with a feed inlet 3 of a coal crusher through a flange; an outer shell 4 is arranged outside the inner shell, the lower end of the outer shell is welded on the coal crusher, and a distance is reserved between the top end of the outer shell and the bottom end of a coal dropping pipe of the coal screening machine; an annular buffer pad 5 made of a pearl wool plate is clamped between the inner shell and the outer shell, namely the inner surface of the buffer pad is contacted with the outer wall of the inner shell, and the outer surface of the buffer pad is contacted with the inner wall of the outer shell; the cylindrical protective cover 6 is arranged outside the outer shell and is made of aviation rubber, the upper end of the protective cover is connected to the lower end of a coal dropping pipe of the coal screening machine through a bolt, and the lower end of the protective cover is connected to the coal breaker through a bolt.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
