The sand collecting unit 31 can be wedge-shaped, has a sand inlet 3102 at one end, and has a sand outlet 3101 at the bottom of the other end. The sand inlet 3102 can be a rectangular port with a size of 5 cm*10 cm. In the case that the sand collecting device 3 includes two sand collecting units 31, a “V”-shaped through structure 32 can be used to connect the sand outlets 3101 of the two sand collecting units 31, and the bottom end of the through structure 32 is connected to the upper end of the sand conveying pipe 5. The number of sand conveying pipes 5 is equal to the number of groups of sand collecting devices 3.
