[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] First, the utility model drives the push rod to rotate by controlling the rotary push mechanism, and the push rod drives the connecting rod on the rotating rod to rotate, driving the blocking cover to be embedded in the blocking groove. At this time, the raw material no longer enters the gold selection equipment body under the blocking of the blocking cover. After the force of the rotary push mechanism on the push rod is released, the rotating rod rotates in the opposite direction under the action of the torsion spring, driving the blocking cover to move away from the blocking groove, and the raw material enters the gold selection equipment body. The function of the raw material intermittently entering the gold selection equipment body is realized, so that the gold selection equipment body has enough time to separate and discharge the separated materials each time the material is fed, thereby improving the gold ore sorting effect and increasing the ore dressing recovery rate.

[0012] Second, in the optimized technical solution of the utility model, the output end of the electric telescopic rod can drive the connection block to move downward, and the connection block moves downward while driving the lifting drive block downward. While the lifting drive block continues to move downward, its inclined surface abuts against the push rod and drives the push rod to rotate, so that the blocking cover is embedded in the blocking groove to block the raw materials. Intermittent feeding operation is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
