DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a vibrating feeder for mine crushing.

[0025] The utility model provides Figure 1-3 The vibrating feeder for mining crushing shown in the figure comprises a frame 1 and a vibration plate 2 arranged inside the frame 1, both ends of the bottom of the vibration plate 2 are fixedly connected to the lower end of the inner wall of the frame 1 through a plurality of vibration springs 3, a vibration motor 4 is fixedly provided at the bottom of the vibration plate 2, a screening net 5 is fixedly embedded inside the vibration plate 2, a feed pipe 6 is connected to the top of the frame 1, a material guide cover 7 is connected to the top of the feed pipe 6, a plurality of dust suction pipes 8 are fixedly penetrated at the upper end of the outer wall of the material guide cover 7, a plurality of dust suction pipes 8 are commonly connected at the bottom thereof with an exhaust fan 9, a plurality of dust suction pipes 8 are connected to the air inlet end of the exhaust fan 9 through a multi-way valve 19, and the exhaust fan 9 is fixedly arranged at the upper end of the outer wall of the frame 1.

[0026] When the vibrating feeder is in use, the vibration motor 4 is started, so that the vibration plate 2 cooperates with the vibration spring 3 to vibrate rapidly, and then the crushed stones in the mine are put into the frame 1 through the guide cover 7 and the feed pipe 6, and are rapidly vibrated by the vibration plate 2 and rapidly screened through the screening net 5. Before this, the exhaust fan 9 is started so that the multiple dust suction pipes 8 can all generate greater suction force. At this time, the dust generated by the crushed stones poured into the guide cover 7 can be quickly sucked and discharged, so as to avoid the dust from escaping into the air and affecting the air quality.

[0027] In order to prevent dust from entering the exhaust fan 9 and affecting the operating stability of the exhaust fan 9 as much as possible during the dust collection process, Figure 2-3As shown, the nozzle of the dust suction pipe 8 is fixedly sleeved with a connecting frame 10, and a rotating rod 11 is rotatably penetrated by the side wall of the connecting frame 10, and a connecting block 12 is fixedly sleeved on the rod wall of the rotating rod 11. Filter plates 13 are provided on both sides of the connecting block 12, and the outer cover of the filter plate 13 is provided with a rubber cover 20. A connecting screw 18 is penetrated inside the filter plate 13, and the connecting screw 18 is connected with the side thread of the connecting block 12. A positioning mechanism is provided on the rod wall of the rotating rod 11, and the positioning mechanism includes a positioning rod 14. Positioning grooves are opened on both sides of the outer wall of the connecting frame 10, and a mounting plate 15 is fixedly provided on the rod wall of the rotating rod 11. A fixing rod 16 is fixedly penetrated inside the mounting plate 15, and the positioning rod 14 is rotatably sleeved on the outer side of the fixing rod 16, and the end of the positioning rod 14 is plugged into the positioning groove, and a pressing spring 17 is fixedly provided between the end of the positioning rod 14 away from the positioning groove and the rotating rod 11, and the positioning rod 14 is L-shaped.

[0028] When the dust is sucked and processed centrally, since the filter plate 13 is arranged at the pipe mouth of the dust suction pipe 8, the dust is collected without entering the exhaust fan 9 and affecting its stability in use. As the dust accumulates on the surface of the filter plate 13, the positioning rod 14 can be pressed to compress the pressing spring 17. At the same time, the end of the positioning rod 14 is lifted up and pulled out from the positioning groove. Then the rotating rod 11 can be rotated to make the connecting block 12 drive the two filter plates 13 to switch positions, and the positioning rod 14 is loosened so that the positioning rod 14 continues to be inserted into the positioning groove under the push of the pressing spring 17 to fix the positions of the two filter plates 13. At this time, the switching of the two filter plates 13 is completed, and the connecting screw 18 is loosened so that the used filter plate 13 can be disassembled and cleaned, thereby ensuring that the two adjacent filter plates 13 can perform continuous and stable dust blocking work.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
