Disclosure of Invention
In view of the above-mentioned drawbacks of the prior art, an object of the present invention is to provide a safety protection mechanism for a coal mining machine, which improves the safety of operators.
The invention provides a safety protection mechanism of a coal mining machine, which comprises the following components: the coal blocking device comprises a coal blocking plate, a first support, an oil cylinder and a second support, wherein the first support and the second support are fixed above a rocker arm, the lower end of the coal blocking plate is hinged with the second support, the lower end of the oil cylinder is hinged with the first support, and the upper end of the oil cylinder is hinged with the coal blocking plate.
The safety protection mechanism is simple in structure and convenient to operate, effectively blocks the thrown coal blocks, and improves the safety of operators. In addition, the coal baffle is erected when the oil cylinder stretches out, and the coal baffle is in a flat state when the oil cylinder retracts. Through the drive of hydro-cylinder, except putting and setting up two kinds of states, the coal baffle can also be set to the state of arbitrary angle with the rocking arm, and the flexibility is good, has increased application range.
Further, the first support and the second support are fixed above the rocker arm through screws or welding.
Further, the coal baffle is arranged from right to left along the upper surface of the rocker arm. The size of the coal blocking plate is increased, the coverage area is increased, and the coal blocking effect is enhanced.
Further, the coal baffle is provided with a through hole. The self weight is reduced under the condition of not affecting the coal blocking effect.
Further, the safety protection mechanism comprises 2 or more than 2 oil cylinders, so that the coal baffle plate is easier to erect and lay flat.
In conclusion, the safety protection mechanism is simple in structure and convenient to operate, can effectively block the thrown coal blocks, and improves the safety of operators. In addition, by increasing the size of the coal blocking plate, the coal blocking effect is enhanced.

Detailed Description
Further advantages and effects of the present invention will become apparent to those skilled in the art from the disclosure of the present invention, which is described by the following specific examples.
Please refer to fig. 1 to 5. It should be understood that the structures, proportions, sizes, etc. shown in the drawings are for illustration purposes only and should not be construed as limiting the invention to the extent that it can be practiced, since modifications, changes in the proportions, or otherwise, used in the practice of the invention, are not intended to be critical to the essential characteristics of the invention, but are intended to fall within the spirit and scope of the invention. Also, the terms such as "upper," "lower," "left," "right," "middle," and "a" and the like recited in the present specification are merely for descriptive purposes and are not intended to limit the scope of the invention, but are intended to provide relative positional changes or modifications without materially altering the technical context in which the invention may be practiced.
Fig. 1 shows a schematic structural view of the safety protection mechanism of the coal mining machine. Fig. 2 shows a schematic diagram of a state of a coal baffle in the safety protection mechanism of the coal mining machine. Fig. 3 shows a second schematic view of a coal baffle in the safety protection mechanism of the coal mining machine. Fig. 4 shows a third schematic view of the state of the coal baffle in the safety protection mechanism of the coal mining machine. Fig. 5 shows a schematic structural diagram of an oil cylinder in the safety protection mechanism of the coal mining machine.
As shown in fig. 1, 2 and 3, safety shield mechanism 100 includes: the coal baffle 01, the first support 02, the oil cylinder 03 and the second support 04. The first support 02 and the second support 04 are fixed above the rocker arm 101 through screws or welding, the lower end of the coal baffle 01 is hinged with the second support 04, the lower end of the oil cylinder 03 is hinged with the first support 02, and the upper end of the oil cylinder 03 is hinged with the coal baffle 01. When the oil cylinder 03 extends out, the coal baffle 01 is erected, and when the oil cylinder 03 retracts, the coal baffle 01 is put flat.
The safety protection mechanism 100 is simple in structure and convenient to operate, effectively blocks the thrown coal, and improves the safety of operators. In addition, by driving the oil cylinder, besides the two states of horizontal and vertical, the coal baffle plate 01 can be set to be in a state of forming an arbitrary angle A with the rocker arm 101, as shown in FIG. 4, the flexibility is good, and the application range is enhanced.
In the preferred embodiment, the coal baffle 01 plate is arranged from right to left along the upper surface of the rocker arm, increasing the size of the coal baffle plate, so that the coverage area is increased, and the coal baffle effect is enhanced.
In another embodiment, the coal baffle 01 is close to the side of the roller, and is blocked when the coal blocks are just thrown out, so that safety accidents are avoided.
The coal baffle 01 is also provided with a through hole H, so that the weight of the coal baffle is reduced under the condition of not affecting the coal baffle effect.
According to the structure of the rocker arm, 2 or more cylinders 03 may be provided in order to make the erection and the leveling of the coal baffle easier, as shown in fig. 5.
In conclusion, the safety protection mechanism is simple in structure and convenient to operate, can effectively block the thrown coal blocks, and improves the safety of operators. In addition, by increasing the size of the coal blocking plate, the coal blocking effect is enhanced.
