[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] See also Figure 1-8A coal mining, filling and tunneling device includes a mining vehicle 1, a crushing box 2 is fixedly connected to the rear side of the mining vehicle 1, support columns 3 are connected to both sides of the mining vehicle 1, and moving parts 5 are connected to the bottom and top of the coal mine at both ends to support the coal mine. The inside of the crushing box 2 is connected to a relatively rotating extrusion block 10, and the top of the crushing box 2 is connected to an active block 6, a driven gear 7 and a hydraulic rod 9, wherein the active block 6 and the driven gear 7 are meshed with each other to extrude and crush the opened coal in the crushing box 2.

[0031] See also Figure 1-5 The outer wall of the supporting column 3 is sleeved with a limiting cross bar 4, and a limiting ring 8 is connected to the supporting column 3 below the limiting cross bar 4. The limiting ring 8 is sleeved on the supporting column 3. By connecting the limiting cross bar 4 and the limiting ring 8 to the supporting column 3, the upper and lower parts of the supporting column 3 can be limited, thereby increasing the stability of the supporting column 3.

[0032] One end of the limiting collar 8 is rotatably connected to the two sides of the mining vehicle 1, and four supporting columns 3 are equidistantly connected to the limiting cross bar 4, and the supporting columns 3 and the limiting cross bar 4 are symmetrically connected to the two sides of the mining vehicle 1, wherein a long rod is connected between the limiting cross bars 4 to fix them, and through the multiple supporting columns 3 connected to the limiting cross bars 4, the pressure inside the coal mine can be dispersedly supported, thereby increasing the force-bearing area of ​​the coal mine, and the long rod connected between the limiting cross bars 4 can fix the supporting columns 3 on both sides of the mining vehicle 1, making the device more stable when in use.

[0033] The moving component 5 includes a roller 501, a limit block 502, a spring member 503 and a center column 504. The top of the center column 504 is inserted into the end of the support column 3 and slides in the support column 3. Through the connection method between the support column 3 and the center column 504, it can be telescopically adjusted according to the environment of the coal mine, making the device more flexible when used.

[0034] The outer wall of the center column 504 is sleeved with a spring component 503, and the two ends of the spring component 503 are respectively abutted against the supporting column 3 and the limit block 502. The spring component 503 connected between the supporting column 3 and the limit block 502 can support and adjust the supporting column 3 and the limit block 502. When the ground of the coal mine is uneven, the limit block 502 is subjected to force to drive the center column 504 to slide in the supporting column 3. At the same time, the spring component 503 expands and contracts according to the situation to adjust the support column 3 and the limit block 502.

[0035] The limit block 502 is connected to the bottom of the center column 504, and the center column 504 is fixed on the limit block 502. The lower part of the limit block 502 is rotatably connected to the roller 501. By connecting the roller 501 to the limit block 502, it can roll in the coal mine according to the movement of the mining vehicle 1, thereby increasing the mobility of the device.

[0036] See also Figure 6-8 The bottom of the hydraulic rod 9 is fixed on the crushing box 2, the output shaft of the hydraulic rod 9 is fixed on one end of the active block 6, the active block 6 is placed on the top of the crushing box 2, and reciprocates on the crushing box 2. The hydraulic rod 9 is a common model on the market and will not be described in detail here. The hydraulic rod 9 is electrically connected to an external power supply. When the hydraulic rod 9 is started, the output shaft of the hydraulic rod 9 pushes the active block 6 to reciprocate, wherein a rack is provided on one side of the active block 6 connected to the driven gear 7, which is meshed with the driven gear 7.

[0037] There are two driven gears 7, which are symmetrically connected on both sides of the active block 6, and rotate relative and oppositely according to the rotation of the active block 6. The driven gears 7 connected on both sides of the active block 6 can not only limit the active block 6 so that the active block 6 can move smoothly on the crushing box 2, but also drive the driven gear 7 to rotate. When the output shaft of the hydraulic rod 9 pushes the active block 6 to move, the active block 6 drives the driven gear 7 to rotate relatively clockwise. When the output shaft of the hydraulic rod 9 pulls the active block 6 to move, the active block 6 drives the driven gear 7 to rotate relatively counterclockwise.

[0038] A fixing column 12 is fixedly connected to the bottom of the driven gear 7, and one end of the fixing column 12 passes through the upper part of the crushing box 2 and is rotatably connected to the bottom of the fixing column 12. By connecting the fixing column 12 to the driven gear 7, when the driven gear 7 rotates, it can drive the fixing column 12 to rotate, wherein two circular through holes are provided on the top of the crushing box 2, and the fixing column 12 passes through the circular through holes provided on the crushing box 2 and rotates in the circular through holes provided on the crushing box 2.

[0039] A connecting block 13 is fixedly connected to one side of the extrusion block 10, and the end of the connecting block 13 away from the extrusion block 10 is sleeved on the fixed column 12. A telescopic baffle 11 is rotatably connected to one end of the extrusion block 10, and the end of the telescopic baffle 11 away from the extrusion block 10 is rotatably connected to the inner wall of the crushing box 2. The extrusion block 10 is in an arc shape, and a cylinder is fixed to the end of the extrusion block 10 connected to the telescopic baffle 11. A circular through groove is opened at one end of the telescopic baffle 11. The cylinder at one end of the extrusion block 10 is inserted into the circular through groove on the telescopic baffle 11 and rotates on the extrusion block 10, wherein the telescopic baffle 11 is away from the extrusion block 10. A protrusion extends from one end of the extrusion block 10, and the protrusion is limited to the inner wall of the crushing box 2 and rotates on the inner wall of the crushing box 2. When the fixed column 12 rotates, it drives the connecting block 13 to rotate, and the connecting block 13 drives the extrusion block 10 to rotate. The extrusion block 10 drives the telescopic baffle 11 to move. At this time, the telescopic baffle 11 is stretched according to the moving direction of the extrusion block 10. The telescopic baffle 11 connected between the extrusion block 10 and the crushing box 2 can prevent the extrusion block 10 from being stuck in the inside of the extrusion block 10 when extruding the coal blocks, and can also gather the coal blocks on both sides of the crushing box 2.

[0040] Working principle: When the mining vehicle 1 mines the coal mine, the staff first starts the hydraulic rod 9, and the moving part 5 on the supporting column 3 is adjusted according to the height of the coal mine, wherein the roller 501 rolls on the top and the ground of the coal mine, and the spring part 503 and the center column 504 on the limit block 502 extend and retract on the supporting column 3. The mining vehicle 1 collects the chiseled coal blocks in the front bucket, and then collects them into the mining vehicle 1 through the front bucket, and then transports them from the mining vehicle 1 to the crushing box 2. The hydraulic rod 9 drives the active block 6 to move back and forth, and the active block 6 drives the fixed column 12 to rotate through the driven gear 7. The fixed column 12 drives the extrusion block 10 to swing through the connecting block 13. The extrusion block 10 rotates around the fixed column 12 to extrude the coal blocks. At this time, the extrusion block 10 drives the telescopic baffle 11 to extend and rotate.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
