Description

Technical Field

[0001] The present invention relates to the field of conveying devices, and particularly to an adjustable coal mining conveying device. Background Art

[0002] In surface coal mining, the overlying rocks and covering materials on the coal seam need to be removed first to expose the coal on the ground surface for mining. The process of removing the soil and rock is called stripping, and the process of extracting the coal is called coal mining.

[0003] During the coal mining process, the coal buried deep underground is first excavated by a crushing device, and then transported through an output belt and conveyed to an external transport vehicle for transfer. After the existing coal is mined and excavated, a large amount of voids are left in the transport vehicle for the relatively large lumps of coal, resulting in a relatively small total weight of the coal carried by the vehicle. At the same time, the conveyor belt cannot be adjusted according to the height to meet the transportation requirements of different heights. Summary of the Invention

A plurality of crushing heads 908 are arranged on the lower surface of the inclined connecting plate 909. The positions of the crushing heads 908 correspond to those of the slag discharge holes 915. By setting the vertical shaft 916, the rotation of the turntable 904 drives the vertical shaft 916 to rotate. Since the vertical shaft 916 is arranged inside the moving plate 917, the rotation of the vertical shaft 916 drives the moving plate 917 to move up and down. The movement of the moving plate 917 drives a plurality of crushing heads 908 to move through the linkage rod 918 and the inclined connecting plate 909.

[0040] As an excellent implementation method in this embodiment, a drive shaft 913 is rotatably connected to the inner wall of the rear protection plate 8. One end of the drive shaft 913 is rotatably connected to the back surface of the front protection plate 8.

[0041] As an excellent implementation method in this embodiment, arc-shaped guide plates 910 are arranged in front of and behind the driven roller 12.

A plurality of sliding holes are opened on the surface of the arc-shaped guide plate 910. The inner wall of the sliding hole is slidably connected with a bolt 923. The bolt 923 is adapted to the inner wall of the jack. By arranging the arc-shaped guide plate 910, the movement of the slider 921 is guided. By arranging the jack and cooperating with the bolt 923, the overall positioning and fixing of the slider 921 are realized. By arranging the sliding hole, a space for the bolt 923 to be inserted and fixed is given.

[0042] In this embodiment, a lifting plate 920 is arranged on the front surface of the slider 921. A limiting support plate 922 is arranged on the inner bottom wall of the arc-shaped guide plate 910. An L-shaped plate 919 is arranged on the right side of the arc-shaped guide plate 910. A through hole is opened on the inner wall of the L-shaped plate 919. The surface of the bolt 923 is slidably connected with the inner wall of the through hole. By arranging the lifting plate 920, it is convenient to drag the lifting plate 920 to change the overall height of the slider 921. By arranging the limiting support plate 922, the lowest point height of the slider 921 is limited. By arranging the L-shaped plate 919, the positioning stability of the bolt 923 is maintained.

[0043] In this embodiment, a force-bearing block 925 is arranged on the surface of the bolt 923. A return spring 924 is sleeved on the surface of the bolt 923. One end of the return spring 924 is fixedly connected to the surface of the force-bearing block 925. The other end of the return spring 924 is fixedly connected to the inner wall of the L-shaped plate 919. By arranging the force-bearing block 925, the movement of the bolt 923 drives the movement of the force-bearing block 925, thereby compressing the return spring 924 to become shorter. By arranging the return spring 924, the force-bearing block 925 and the bolt 923 as a whole are driven to reset.

[0044] As an excellent implementation method in this embodiment, a rotating shaft 927 is provided on the inner wall of the driven roller 12. The front end of the rotating shaft 927 is rotatably connected to the back surface of the front slider 921. The rear end of the rotating shaft 927 penetrates through the back surface of the rear slider 921. A third driven wheel 914 is provided on the surface of the rotating shaft 927. A same third belt 911 is provided on the surfaces of the third driven wheel 914 and the third driving wheel 912. By providing the rotating shaft 927, the stability of the driven roller 12 is maintained. By providing a same third belt 911 on the surfaces of the third driven wheel 914 and the third driving wheel 912, the rotation of the third driving wheel 912 drives the third driven wheel 914 to rotate through the third belt 911, and the rotation of the third driven wheel 914 drives the entire rotation of the rotating shaft 927 and the driven roller 12.

[0045] The working principle of the present invention is as follows: For the adjustable mine transportation device, when the user uses it, the motor 5 is started. The output end of the motor 5 drives the rotating shaft to rotate. The rotation of the rotating shaft drives multiple mining discs 6 to rotate, and mining operations are carried out on the coal mine underground. After the mined coal drops onto the collection inclined box 2 and is at the lowest position inside the collection inclined box 2, the rotation of the rotating shaft drives the first driving wheel 901 to rotate. The rotation of the first driving wheel 901 drives the first driven wheel 903 to rotate through the first belt 902. The rotation of the first driven wheel 903 drives the linkage shaft 905 to rotate. The rotation of the linkage shaft 905 drives the turntable 904 and the second driving wheel 926 to rotate. The rotation of the turntable 904 drives the vertical shaft 916 to rotate. Since the vertical shaft 916 is arranged inside the moving plate 917, the rotation of the vertical shaft 916 drives the moving plate 917 to move up and down. The movement of the moving plate 917 drives multiple crushing heads 908 to move through the linkage rod 918 and the inclined connecting plate 909. The moving crushing heads 908 are inserted into the slag discharge holes 915 to crush the coal mine above the slag discharge holes 915. The crushed coal mine is discharged onto the conveyor belt 11 through the slag discharge holes 915. The rotation of the second driving wheel 926 drives the second driven wheel 907 to rotate through the second belt 906, and further drives the drive shaft 913 to rotate. The rotation of the drive shaft 913 drives the driving roller 10 and the third driving wheel 912 to rotate. The rotation of the third driving wheel 912 drives the third driven wheel 914 to rotate through the third belt 911. The rotation of the third driven wheel 914 drives the integral rotation of the rotating shaft 927 and the driven roller 12. Under the rotation action of the driven roller 12 and the driving roller 10, the conveyor belt 11 is driven to rotate and convey the crushed coal mine on the conveyor belt 11. When it is necessary to adjust the final discharging height on the conveyor belt 11, the pin 923 is pulled outwards. The movement of the pin 923 drives the force-bearing block 925 to move. The movement of the force-bearing block 925 compresses the return spring 924 and shortens it. At this time, the positioning restriction on the slider 921 is released. The lifting plate 920 is pulled upwards to drive the overall height movement of the slider 921. When it stays at a suitable height, the corresponding pin 923 is reinserted and fixed in the slider 921 to fix the slider 921. Since the arc of the arc-shaped guide plate 910 is taken from an arc with the driving roller 10 as the center of the circle, the slider 921 slides within the arc-shaped guide plate 910, and the distance between the driven roller 12 and the driving roller 10 remains unchanged and stable. With the above structure, by setting the adjustment and crushing mechanism 9, larger coal mines are crushed, and the final discharging height of transportation is adjusted.
