When the first guide plate 63 is located above the first cylinder 61, the sand can slide off the first guide plate 63 after passing through the first screen 9. When the second guide plate 64 is located above the first cylinder 61, the sand can slide off the second guide plate 64 after passing through the second screen 11.
[0027] The bottom of the first material guide plate 63 and the upper surface of the second material guide plate 64 are fixedly connected with support columns 13.
