[0012] In an embodiment of the present application, one side of the base frame is fixedly connected with a supporting seat, which is arranged on the upper part of the hard supporting part and below the main frame body.

[0013] In an embodiment of the present application, the front end of the supporting seat is rotatably connected with a strong hydraulic supporting rod, which is rotatably connected with the bottom of the main frame body.

[0014] In an embodiment of the present application, the bottom of the strong hydraulic supporting rod is fixedly connected with a bottom rotating shaft, which is rotatably connected with the supporting seat, and the top end of the strong hydraulic supporting rod is fixedly connected with a rotating sleeve.

[0015] In an embodiment of the present application, the upper part of the main frame body is provided with a sliding groove, the bottom of the main frame body is fixedly connected with a supporting frame, the middle of the supporting frame is fixedly connected with a fixed column, the fixed column is rotatably connected with the rotating sleeve, and the middle of the main frame body is fixedly connected with a lower cylinder.

[0016] In an embodiment of the present application, the top of the stretching frame body is fixedly connected with an upper cylinder.

[0017] In an embodiment of the present application, the stretching assembly comprises a first spring adjusting telescopic rod, a second spring adjusting telescopic rod and a movable wheel, the tail end of the first spring adjusting telescopic rod is fixedly connected with an upper rotating sleeve, the upper rotating sleeve is rotatably sleeved on the outside of the upper cylinder, the front end of the first spring adjusting telescopic rod is fixedly connected with a first rotating connecting frame, the tail end of the second spring adjusting telescopic rod is fixedly connected with a lower rotating sleeve, the lower rotating sleeve is rotatably sleeved on the outside of the lower cylinder, the front end of the second spring adjusting telescopic rod is fixedly connected with a second rotating connecting frame, the two ends of the movable wheel are rotatably connected with the first rotating connecting frame and the second rotating connecting frame respectively, and the movable wheel is matched with the conveying belt.

[0020] The present application has the following beneficial effects:

[0021] 1、The rotation of the rotating disc can drive the whole device to rotate 360 degrees, and can transport gangue at any angle. The main frame body is pushed to change the angle by the strong hydraulic support rod.

[0022] 2、When the strong hydraulic support rod is extended, the elevation angle of the main frame body increases, and the height of gangue transportation increases. When the strong hydraulic support rod is retracted, the elevation angle of the main frame body decreases, and the height of gangue transportation decreases. The transportation height of gangue is conveniently adjusted by controlling the extension and retraction of the strong hydraulic support rod.

[0023] 3、When the main frame body and the stretching frame body need to be extended, the cooperation of the first spring adjusting telescopic rod and the second spring adjusting telescopic rod makes the movable wheel continuously contact the inner side of the conveying belt. When the stretching frame body and the main frame body are extended, the first spring adjusting telescopic rod and the second spring telescopic rod are retracted at the same time, and the movable wheel is retracted synchronously, so that the conveying belt is loosened to cooperate with the lengthening of the stretching frame body and the main frame body. Gangue can be transported to a farther place. When the stretching frame body and the main frame body are retracted, the first spring adjusting telescopic rod and the second spring adjusting telescopic rod are extended at the same time under the action of the spring, and the movable wheel is moved outward synchronously, so that the conveying belt is tightened to cooperate with the shortening of the length of the stretching frame body and the main frame body. The loosening of the conveying belt is adjusted very conveniently, and gangue can be transported to a closer place. The outward movement and retraction of the movable wheel are automatically changed according to the length of the stretching frame body and the main frame body.

[0024] 4、The tail end of the stretching frame body is extended and retracted from the top end of the main frame body by the extension and retraction of the side hydraulic support rod, which can adjust the transportation distance of gangue. When the transportation distance of the main frame body and the stretching frame body is increased, the first spring adjusting telescopic rod and the second spring adjusting telescopic rod need to loosen the conveying belt. When the transportation distance of the main frame body and the stretching frame body is reduced, the first spring adjusting telescopic rod and the second spring adjusting telescopic rod need to tighten the conveying belt. Therefore, the change of the transportation distance between the main frame body and the stretching frame body needs to change the loosening state of the conveying belt.

[0025] Through the above operation, the device can not only adjust 360 degrees during gangue transportation, but also change the transportation elevation angle of gangue and the transportation distance of gangue, and can flexibly adapt to the height difference of different sites to transport gangue to the specified place. The adjustment time is short, and the gangue transportation efficiency is increased. BRIEF DESCRIPTION OF DRAWINGS
