The working principle of the invention is as follows: firstly, a first servo motor 2 is started, a screw rod 3 can convey metal ore taken out by an ore taking machine into a feeding pipeline 7, then a fan 51 is started, dust on the surface of the metal ore can be blown off and scattered in the feeding pipeline 7, an electrostatic dust collector 52 can absorb the dust scattered in the feeding pipeline 7, the metal ore in the feeding pipeline 7 directly falls into a metering box body 12, when the weight of the metal ore in the metering box body 12 reaches a certain value, a second spring 123 below a material receiving plate 14 can be compressed to the limit, meanwhile, the material receiving plate 14 triggers a gravity sensor 13 below the material receiving plate 14, the gravity sensor 13 can accurately monitor the change of the weight, and start signals are respectively sent to an air cylinder 38 and an electromagnet 71 through a controller 9, after the electromagnet 71 is electrified, a baffle plate 8 can prevent the metal ore in the feeding pipeline 7 from continuing to be blanked, on the other hand, the air cylinder 38 drives a transmission plate 35 to move downwards through a piston rod 37, the shaft pin 34 on one side of the driving rod 33 slides along the sliding groove 351 on the surface of the driving plate 35 and drives the driving shaft 10 to rotate, when the piston rod 37 moves downwards to the stroke limit, the rotation angle of the piston rod 37 is just 180 degrees, at this time, the metering box body 12 filled with metal ore can pour the metal ore into the ball milling tank 20 below, another empty metering box body 12 can return to the feeding pipeline 7 again to continue receiving the material, the material is circulated in a reciprocating mode, the second servo motor 27 is started to drive the ball milling tank 20 to rotate at a high speed, and the hard metal balls 22 flying in a parabola shape collide with the metal ore to produce hard alloy powder.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
