[0019] The present invention is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present invention will become clearer and more specific. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0020] like Figures 1 to 4 As shown, this embodiment discloses an underground mineral material conveying device with adjustable conveying angle and direction, including a walking platform 7, a lifting mechanism and a screw conveyor 6; in this embodiment, the walking platform includes a walking frame and walking wheels installed on the walking frame, and preferably, a shipping connecting ring 9 is provided at one end of the walking frame so that the device can be moved underground by a winch.

[0021] The lifting mechanism is assembled with the walking platform for horizontal rotation, and the lifting mechanism and the walking platform are rotated and positioned by a rotation positioning mechanism, and the middle part of the screw conveyor is swing-hinged with the execution end of the lifting mechanism; in this embodiment, the lifting mechanism includes an outer cylinder 2, an inner cylinder 4 and an electric push rod 8, the middle part of the screw conveyor is swing-hinged with the top of the outer cylinder, the outer cylinder is assembled with the inner cylinder for vertical sliding, and the bottom of the inner cylinder is assembled with the walking platform for horizontal rotation by a slewing bearing, the electric push rod is arranged inside the inner cylinder, the execution end of the electric push rod is connected with the outer cylinder, and the non-execution end is connected with the slewing bearing; in this embodiment, the slewing bearing includes a rotating disk 11 fixedly connected with the bottom of the inner cylinder, a fixed seat 13 fixedly mounted on the walking platform, and a ball 12 arranged between the rotating disk and the fixed seat; it can be understood that: in the specific implementation, ear plates can be arranged at the middle part of the screw conveyor and the top of the outer cylinder, and then the swing-hinged assembly of the two can be realized by a pin shaft passing through the ear plate, which is conducive to improving the rationality of assembly.

[0022] Preferably, the side wall of the inner cylinder is provided with a guide pin 3, and the side wall of the outer cylinder is provided with a guide groove 10 slidably assembled with the guide pin; through the sliding fit between the guide pin and the guide groove, sliding guidance between the outer cylinder and the inner cylinder can be achieved.
