[0028] like Figure 1 , Figure 3 and Figure 5 The cutter body 1 with the accommodating chamber 2 and the hydraulic cutter 3 is the prior art, which can cut the mining anchor ring located in the accommodating chamber 2. The top and bottom of the adjusting baffle 101 are in contact with the cutter body 1, and the adjusting connecting rod 5 and the adjusting hole 4 are slidably connected, so that the adjusting baffle 101 can only move horizontally.

[0029] The inner wall of the adjusting hole 4 is provided with a limiting cavity 10 , and the adjusting connecting rod 5 is fixedly connected with a limiting protrusion 11 , and the limiting protrusion 11 and the limiting cavity 10 are slidably connected.

[0030] like Figure 1 and Figure 3 Through the sliding connection between the limiting protrusion 11 and the limiting cavity 10 , the adjusting connecting rod 5 cannot be separated from the adjusting hole 4 , and the adjusting baffle 101 will not be completely separated from the cutter body 1 .

[0031] A positioning recess 12 is disposed on one side of the adjusting baffle 101 close to the splitter body 1 , and a positioning protrusion 13 for use with the positioning recess 12 is fixedly connected to the splitter body 1 .

[0032] like Figure 1 and Figure 2 When the adjusting baffle 101 moves toward the direction close to the cutter body 1 , the positioning protrusion 13 can be inserted into the positioning recess 12 to position the movement of the adjusting baffle 101 .

[0033] A fixing sleeve 14 is fixedly connected to the cutter body 1 , a tension spring 15 is fixedly connected to the bottom of the inner wall of the fixing sleeve 14 , and a movable slip ring 16 is fixedly connected to the top of the tension spring 15 .

[0039] The working principle of a mining cutter provided by the utility model is as follows:

[0040] When it is necessary to move the mining anchor ring into the accommodating cavity 2 and cut the mining anchor ring, one end of the mining anchor ring can be directly passed through the accommodating cavity 2;

[0041] When both ends of the mining anchor ring 2 are in a connected state, or the anchor ring is too long to pass directly through the accommodating chamber 2 in a limited space, the movable link 17 can be pulled upward to drive the U-shaped clamping sleeve 9 to move upward. At this time, the U-shaped clamping sleeve 9 and the positioning rod 8 are separated, and then the control pull plate 6 is pulled to one side to drive the adjustment link 5 and the adjustment baffle 101 to move away from the splitter body 1. At this time, an opening is formed between the bottom of the adjustment baffle 101 and the splitter body 1, and the anchor ring can be moved from the formed opening to the accommodating chamber 2;

[0042] Then push the adjusting baffle 101 toward the direction of the cutter body 1, loosen the movable connecting rod 17, and the tension spring 15 contracts to pull down the movable slip ring 16. The movable slip ring 16 drives the U-shaped clamping sleeve 9 to move downward through the movable connecting rod 17. The U-shaped clamping sleeve 9 is sleeved on the positioning rod 8 to position the positioning rod 8 and the adjusting baffle 101.

[0043] Compared with the related art, the mining cutter provided by the utility model has the following beneficial effects:

[0044] The utility model provides a movable adjusting baffle 101 on the cutter body 1, and utilizes the movement of the adjusting baffle 101 so that the mining anchor ring can not only directly pass through the accommodating cavity 2 for cutting, but also can move from the opening formed between the bottom of the adjusting baffle 101 and the cutter body 1 to the inside of the cutter body 1 when the adjusting baffle 101 and the cutter body 1 are separated, so as to facilitate the cutting of the mining anchor ring when the two ends of the mining anchor ring are in a connected state or the mining anchor ring is too long to directly pass through the accommodating cavity 2 in a limited space.

[0045] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
