Referring to fig. 1-3, a screening device for raw ores in this embodiment includes a chassis 1 and a screening device installed on the chassis 1, a first gear 8 is fixedly connected to the outer side of the right end of the screening device, a linkage assembly in transmission connection with the first gear 8 is provided on the chassis 1, a support 16 is fixedly connected to the outer end of the linkage assembly, a double-ring frame 17 is fixedly connected to the outer side of the support 16, three buckets 18 are fixedly connected to the double-ring frame 17, two groups of struts 14 are fixedly connected to the outer side of the linkage assembly, baffles 15 in sliding contact with the inner side of the double-ring frame 17 are fixedly connected to the tail end of each group of struts 14, the baffles 15 are arc-shaped, a guide bin 20 extending to the inside of the screening device is arranged between the tops of the two baffles 15, the guide bin 20 is inclined, the top on the right side of the guide bin 20 is equal to the length of the bucket 18, and the width of the guide bin 20 is equal to the distance between the opposite sides of the tops of the two baffles 15.

In this structure, through the cooperation between screening installation and the linkage subassembly, drive the double-ring frame 17 and rotate, consequently can drive three scraper bowl 18 indirection and shovel up the former ore deposit in the ore bin, baffle 15 can prevent that former ore deposit in the scraper bowl 18 from spilling simultaneously, until scraper bowl 18 reaches the top, the former ore deposit in the scraper bowl 18 can be transmitted to screening installation through guide silo 20 and carry out screening treatment, consequently can effectively avoid lasting the material loading to cause the jam, influence the effect of screening, also can reduce the load of screening time simultaneously.

Wherein, in order to realize screening and transmission, screening facility is including fixing two bearing frame 2 on chassis 1, rotate between the inboard of two bearing frames 2 and be connected with the column 3, the outside and the 8 fixed connection of gear No. 8 of column 3 left end, four support frames 4 of 3 outside fixedly connected with of column, fixedly connected with screen drum 5 between the outer end of four support frames 4, screen drum 5 divide into three screening areas, screen drum 5 is the slope form, chassis 1 is located the below department of screen drum 5 and is fixed with four discharging pipes 6, the left side fixed mounting of a left side bearing frame 2 has driving motor 7 who is connected with the column 3. The rotary column 3 is driven to rotate by the driving motor 7, and the rotary column 3 drives the screen drum 5 to rotate by the four supporting frames 4 to finish screening of raw ores.

In addition, the transmission and the indirect conveying of the raw ore are realized. The linkage assembly comprises a second bearing seat 9 and a third bearing seat 21 which are respectively and fixedly installed on the underframe 1, a top mountable jacking column of the first bearing seat 2 and the second bearing seat 9 on the right side supports the bottom of the guide bin 20, the second bearing seat 9 is located below the first bearing seat 2 on the right side, a connecting column 12 is fixedly connected to the inner side of the second bearing seat 9, a second gear 11 is fixed to the outer side of the connecting column 12, a rotating rod 10 is fixed to the inner side of the third bearing seat 21, a third gear 13 meshed with the second gear 11 is fixed to the outer side of the rotating rod 10, and the third gear 13 is meshed with the first gear 8. When the screen drum 5 rotates, the first gear 8 can follow to rotate, so the first gear 8 drives the second gear 11 to rotate through the third gear 13, the second gear 11 drives the double-ring frame 17 to rotate through the rotating rod 10 and the support 16, the double-ring frame 17 drives the bucket 18 to scoop up raw ores in the ore bin for conveying, linkage transmission is completed, and raw ores can be indirectly conveyed for screening.

The working principle of the embodiment is as follows:

through installing chassis 1 in the ore bin position, then start driving motor 7, driving motor 7 is under the support of bearing frame 2 No. 1, drive the column 3 and rotate, column 3 passes through support frame 4 and drives screen drum 5 and continue to rotate, simultaneously column 3 also can drive gear 8 and rotate in step, because gear 13 and gear 8 and No. two gear 11 mesh, consequently, bull stick 10 passes through support 16 and drives the dicyclo frame 17 rotation, consequently, three scraper bowl 18 can simultaneously rotate and shovel up the former ore, baffle 15 passes through branch 14 fixed connection, simultaneously also with dicyclo frame 17 sliding connection, consequently, baffle 15 does not follow the rotation, thereby the former ore deposit in the scraper bowl 18 drops, until the scraper bowl 18 moves to the top, the former ore deposit in the scraper bowl 18 can accomplish to shovel up and throw in through the distance between two baffle 15 tops and the bottom, simultaneously because three scraper bowl 18 are separated by a distance, thereby realize indirection material loading, the former ore deposit can enter into screen drum 5 through guide bin 20, drive the former ore left side and remove under the screen drum 5 rotation state, thereby can pass through three upper and lower effect of the screen drum 5 and the effect that can be more screen drum 5 is blocked up, thereby, the effect can be improved.

The entire workflow is completed and what is not described in detail in this specification is well known to those skilled in the art.
