[0034] According to a further optimized solution, the first gear set includes a first spur gear 9 and a spur gear ring 10 that are meshed with each other, the first spur gear 9 is fixedly connected to the output shaft of the motor 5, and the spur gear ring 10 is circumferentially fixedly connected to the side wall of the smelting tube 3.

[0035] The motor 5 drives the spur gear ring 10 to rotate through the first spur gear 9, so that the spur gear ring 10 drives the smelting tube 3 to rotate.

[0040] Further optimized solution, the crushing assembly includes a pair of crushing rollers 19, the pair of crushing rollers 19 are rotatably connected in the crushing box 7, and the shafts of the pair of crushing rollers 19 are respectively connected to any transmission rod 8 parallel to the crushing rollers 19 through the fourth gear set.

[0041] When the transmission rod 8 fixedly connected with the fourth spur gear 20 rotates, the fourth spur gear 20 is driven to rotate synchronously, so that the fourth spur gear 20 drives the fifth spur gear 21 meshing therewith to rotate, so that the two fifth spur gears 21 rotate relative to each other, so that the pair of crushing rollers 19 rotate relative to each other, achieving a crushing effect.

[0042] Further optimized solution, the dumping assembly includes a pair of support rods 22, the support rods 22 are fixedly connected to the base 1, the pair of support rods 22 are symmetrically located on both sides of the heating cylinder 2, the support rods 22 are rotatably connected to the third connecting rod 23, the third connecting rod 23 is fixedly connected to the heating cylinder 2, the third connecting rod 23 is fixedly connected to the push plate 24, and a hydraulic cylinder 25 is hinged between the push plate 24 and the base 1.
