The transverse traction wheel group 6 and the transverse guide wheel group 4 are located between the longitudinal traction wheel group 8 and the longitudinal guide wheel group 2.

[0023] In this embodiment, a rotary motor for driving the transverse traction wheel set 6 to rotate can be installed on the third mounting plate 7 to actively pull out the cut ferrosilicon alloy rods 28 from the cutting mechanism.

[0024] Specifically, the cutting mechanism includes a cutting workbench 10 and a bracket 12. The bracket 12 is fixed on the cutting workbench 10. A hydraulic cylinder 13 is installed in the middle position of the top of the bracket 12. A cutting knife 14 is installed at the end of the piston rod of the hydraulic cylinder 13. Two lower cutting supports 11 are installed on the top of the cutting workbench 10. An arc-shaped groove is provided on the top of the lower cutting support 11 to allow the ferrosilicon alloy rod 28 to pass through. A gap is left between the two lower cutting supports 11. The gap is located directly below the cutting knife 14, and the width of the gap is not less than the width of the cutting knife 14. The top of the cutting workbench 10 directly below the cutting knife 14 is opened. A reserved groove is provided, the width of which is not less than the width of the cutting knife 14, and a pair of parallel dovetail guide grooves are provided at the bottom of the cutting workbench 10; the guiding mechanism includes a pair of first guide rails 15 fixed in parallel to the top of the frame 1, and the cutting workbench 10 is slidably installed on the first guide rails 15 through the dovetail guide grooves; a rack 16 is provided on the top of the first guide rail 15, and a through groove allowing the rack 16 to pass through is provided in the dovetail guide groove of the cutting workbench 10, and a gear 17 is rotatably installed in the through groove, the gear 17 is meshed with the rack 16, and the gear 17 is connected to the output shaft of the driving motor 18 arranged on the rear side of the cutting workbench 10.

[0025] In this embodiment, the driving motor 18 drives the gear 17 to rotate, so that the cutting workbench 10 adjusts its position along the first guide rail 15, and the hydraulic cylinder 13 drives the cutting knife 14 to cut the ferrosilicon alloy rod 28 downward.

[0026] Specifically, an auxiliary clamping mechanism is installed on the inner side of the bracket 12, and the auxiliary clamping mechanism includes a support plate 19, an upper pressure block 21, an adjusting screw 23, a first spring 20, and a second spring 24.
