Description

Technical Field

[0001] The invention relates to the technical field of mine car unloading, and in particular to a mine car unloading auxiliary machine. Background Art

[0002] In mining, mine cars are often needed to transport bulk materials such as ore, coal and waste rock. When working, the mine car moves along the guide rails laid on the ground of the underground tunnel. After transporting the ore to the mouth of the chute, the material can be dropped out of the hopper by flipping the hopper of the mine car.

[0003] Existing workers usually use curved track side-unloading mine cars when using mine cars. The unloading curved track can automatically flip the hopper of the mine car, thereby realizing automatic unloading. Compared with the traditional manual push hopper flipping, it can save manpower. However, although this method can realize automatic unloading, the material in the hopper is prone to residue during unloading, resulting in subsequent manual labor to spend extra time to clean out the residual material from the hopper, which is not only troublesome, but also time-consuming and labor-intensive. Summary of the invention

[0004] In view of this, the present invention provides a mine car unloading auxiliary machine, which can solve the disadvantage that when the existing curved track side-unloading mine car is unloading, the material in the hopper is easily left, which makes the subsequent cleaning not only troublesome but also time-consuming and labor-intensive.

The mine car is installed on the track, the hopper is rotatably connected to the mine car, and the hopper can be used to load materials, so that the mine car uses the track to transport the materials in the hopper, the baffle is rotatably connected to the hopper, the baffle is used to block the materials in the hopper, the push plate is slidably connected to the hopper, the two ends of the pull rope I are respectively connected to the baffle and the push plate, so that when the baffle is rotated to open, the push plate can be pulled by the pull rope I to move, so that the push plate can push the material in the hopper out, the flipping mechanism is used for the hopper to flip and unload, the opening and closing mechanism is used to drive the baffle to rotate and open, and the reset mechanism is used for the push plate to reset when it moves.

[0006] Furthermore, the flipping mechanism includes a rotating rod, an elastic member I and a limiting wheel. The rotating rod is rotatably connected to the hopper, and the two ends of the elastic member I are respectively connected to the rotating rod and the hopper.

[0008] Furthermore, the driving assembly includes a servo motor and a winding wheel, the servo motor is connected to the hopper, the winding wheel is connected to the output shaft of the servo motor, and the pull rope II is wound around and connected to the winding wheel, so that the servo motor can unwind the pull rope II by driving the winding wheel to rotate.

[0009] Furthermore, the opening and closing mechanism includes a guide tube and a movable tube, the guide tube is connected to the hopper, and the movable tube is connected to the baffle, so that the movable tube can rotate along with the baffle, and the movable tube is slidably connected to the guide tube, so that the movable tube can be guided by the guide tube when rotating.

[0010] Furthermore, the opening and closing mechanism also includes a limiting ring, which is connected to the guide tube, and the pull rope II passes through the limiting ring, so that the limiting ring can guide and limit the pull rope II.

[0011] Furthermore, the reset mechanism includes a connecting frame, a slide plate, a connecting rope, a guide wheel and an elastic member II, the connecting frame is connected to the hopper, the slide plate is slidably connected in the connecting frame, and the two ends of the connecting rope are respectively connected to the push plate and the slide plate, so that the push plate can drive the slide plate to move through the connecting rope when moving, the guide wheel is rotatably connected to the hopper, and the connecting rope bypasses the guide wheel, so that the guide wheel can be used to guide the connecting rope, and the two ends of the elastic member II are respectively connected to the slide plate and the connecting frame, so that the slide plate can be reset through the elastic member II after moving, thereby driving the push plate to move and reset.

[0012] Furthermore, a cleaning mechanism is also included, which includes a cleaning frame and a brush I. The cleaning frame is connected to the curved track, and the brush I is connected to the cleaning frame. The brush I is used to clean the residue on the limiting wheel.

[0014] Furthermore, a brush II is also included, and the brush II is connected to the curved track and the limiting shell respectively, and the brush II is used to prevent foreign matter from entering the curved track.

[0015] The beneficial effects of the present invention are: 1. When the baffle is rotated and opened for unloading, the push plate is pulled backward by the pull rope I, so that the push plate can push the ore and other materials remaining in the hopper backward, thereby unloading the ore and other materials remaining in the hopper. In this way, it can help people clean up the materials remaining in the hopper, saving time and effort.

[0016] 2. The present invention provides a cleaning frame and a brush I, so that the brush I can brush off the residue on the limiting wheel to prevent the residue from affecting the rolling of the limiting wheel in the curved track.
