In terms of environmental protection, most of the traditional devices have no dustproof measures during unloading. When the coal is poured, a large amount of dust will be generated, which not only pollutes the surrounding environment and harms the health of operators, but also may cause safety hazards such as dust explosion due to dust accumulation. In addition, the moving flexibility of the transportation device needs to be improved.

DETAILED DESCRIPTION
[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0025] Reference Figure 1 and Figure 4The utility model provides a kind of coal mine dustproof coal conveying device, including shell 1, shell 1 top side is fixedly connected with feed inlet 2, shell 1 front end is equipped with slot 12, baffle 10 is slidably connected in slot 12, baffle 10 top side is fixedly connected with handle 11, shell 1 front end is connected with dustproof plate 13 by connecting plate 15, shell 1 bottom side is connected with fixed frame 6 by connecting block 20, fixed frame 6 rear end is fixedly connected with placing box 5, placing box 5 outer wall is provided with protective layer 23, placing box 5 is provided with electric push rod 22, the drive end of electric push rod 22 is connected with the rear bottom end of shell 1, the front end of shell 1 is fixedly connected with fixed plate 17, and fixed plate 17 rear side is rotatably connected with auger blade 16.The top of two connecting plates 15 is engaged with the outer wall of two limit posts 14.The proximal end of two connecting blocks 20 is slidably connected to the inner wall of the sliding slot 21.The top rear end of shell 1 is provided with pulley 3, the front side of pulley 3 is provided with motor, the outer wall of pulley 3 is provided with synchronous belt 24, and the outer wall of pulley 3 is connected with the rear end of auger blade 16 through synchronous belt 24.The front end of dustproof plate 13 is provided with clamping groove 25, and the bottom side of dustproof plate 13 is fixedly connected with slide bar 8.The left and right sides of shell 1 are provided with limit slot 19, and the proximal end of two slide bars 8 is slidably connected to the inner wall of limit slot 19.The left and right sides of fixed frame 6 are fixedly connected with support 7, and the bottom end of two supports 7 is provided with roller 9, and the top end of placing box 5 is fixedly connected with push rod 4.
[0026] Specifically, the operator first holds the push rod 4, pushes the entire device by the roller 9 at the bottom side of the shell 1, until it is transported to the predetermined position, and after reaching the specified position, the electric push rod 22 in the placing box 5 is turned on. The drive end of the electric push rod 22 will lift the shell 1 upward, so that the shell 1 forms a certain inclination angle. In this process, the connecting block 20 at the front end of the shell 1 will slide on the outer wall of the fixed frame 6, and the connecting block 20 and the part sliding on the outer wall of the fixed frame 6 are connected in a rotating manner. Such design is to prevent the coal from not being completely poured out from the inside of the shell 1 when the electric push rod 22 lifts the shell 1 due to the fixed inclination angle. Considering that the specifications of the coal stored in the shell 1 may differ, to prevent blockage during discharging, the pulley 3 can be started during the process of pouring coal. The pulley 3 is driven by the synchronous belt 24, thereby driving the auger blade 16 to rotate, and the coal is pushed out of the shell 1 by the rotation of the auger blade 16, ensuring smooth discharging process.
[0027] Refer to Figure 2 , the front end of shell 1 is fixedly connected with two rotating shafts 18, the outer wall of two rotating shafts 18 is rotatably connected with connecting plate 15, and the front side of dustproof plate 13 is fixedly connected with limit post 14;
[0028] Specifically, before the shell 1 begins to tilt, the baffle 10 needs to be pulled out from the slot 12 at the front end of the shell 1. Then, the connecting plate 15 outside the rotating shaft 18 is rotated to disengage from the limiting column 14, thereby releasing the position limitation of the dustproof plate 13.
[0029] Referring to Figure 3 The left and right sides of the shell 1 are rotatably connected with connecting blocks 20, and the left and right sides of the fixed frame 6 are provided with sliding grooves 21.
[0030] Specifically, after the position limitation is released, the coal in the shell 1 begins to be output as the shell 1 tilts. At this time, the dustproof plate 13 slides in the limiting groove 19 on the outer wall of the shell 1 by means of the slide strip 8 at the bottom end of the dustproof plate 13, and gradually extends out of the front end of the shell 1 to play a dustproof role on the output position of the coal.
[0031] Working principle: the operator moves the shell 1 as a whole by pushing the push rod 4, and the rollers 9 at the bottom side of the shell 1 can drive the device as a whole to move. After the coal is transported to the predetermined position, the electric push rod 22 in the placing box 5 is started, the driving end of the electric push rod 22 props up the shell 1 as a whole to make the shell 1 have a tilt angle, and the connecting block 20 at the front end of the shell 1 can slide on the outer wall of the fixed frame 6. The part of the connecting block 20 that slides on the outer wall of the fixed frame 6 is rotatably connected with the connecting block 20, so as to avoid that the tilt angle is fixed when the driving end of the electric push rod 22 lifts up the shell 1 as a whole, which is not conducive to the coal in the shell 1 to be completely poured out. Before the shell 1 tilts as a whole, the baffle 10 is pulled out from the slot 12 at the front end of the shell 1, and then the connecting plate 15 outside the rotating shaft 18 is rotated to disengage from the limiting column 14, thereby releasing the position limitation of the dustproof plate 13. After the position limitation is released, the dustproof plate 13 can slide in the limiting groove 19 on the outer wall of the shell 1 by means of the slide strip 8 at the bottom end of the dustproof plate 13 when the shell 1 tilts as a whole to output the coal in the shell 1, so that the dustproof plate 13 extends out of the front end of the shell 1 to play a dustproof role on the output position of the coal. In order to avoid that the output position is blocked due to different specifications of the coal stored in the shell 1, the belt pulley 3 can be started to rotate the auger blade 16 by the synchronous belt 24 transmission when the coal is poured out.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application.
