As shown in fig. 3 and 4, the concave portion 152 includes two

side surfaces

1523 and 1524 and an arc surface opposite to the opening 121 when the sand silo 120 rotates, the two

side surfaces

1523 and 1524 and the arc surface are similar to the shape of the sand silo 120, and the

guide grooves

1521 and 1522 extend along the arc surface of the concave portion 152 from top to bottom in the direction of the drain opening 151. A connecting frame 158 connected to the sand silo 120 is provided above the

side surfaces

1523, 1524, and the drain port 151 is provided at the lowest position in the middle of the recess 152. The discharge opening 151 divides the arc surface of the recess 152 into a front section 1526 and a rear section 1525, a guide groove 1522 is arranged on the front section 1526, and a guide groove 1521 is arranged on the rear section 1525.

The roller 154 is used for lifting the sand silo 120, so that a set gap exists between the sand silo 120 and the cambered surface, and the range of the gap is set to be 2-5 mm.

The

guide grooves

1521 and 1522 are provided as a complete strip, the width dimensions of the

guide grooves

1521 and 1522 are both greater than (or equal to) the width dimension of the opening 121, and the rollers 154 are located on both sides of the

guide grooves

1521 and 1522. The depth of the recess in the guide grooves 1521 and 1522 at the position where the drain port 151 is connected is set in the range of 2 to 8 mm.
