A support column 17 and a hydraulic cylinder 18 are arranged at the bottom of the water filtering frame 8; a water filtering plate 9 is arranged at the end part of a push rod of the hydraulic cylinder 18; when the push rod of the hydraulic cylinder 18 is in the shortest state, the support column 17 props against the water filter plate 9 to assist the hydraulic cylinder 18 to bear the weight; and the bottom surface of the water filtering frame 8 and the water filtering plate 9 are both provided with water filtering through holes 19. When the water filtering frame 8 moves to the rightmost side along with the crawler belt 11, the water filtering frame 8 is turned downwards, and the hydraulic cylinder 18 ejects the water filtering plate 9 and the ore on the water filtering plate 9; water can flow out of the water filtering through holes 19.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
