Embodiment Construction
[0029] like Figure 1 to Figure 16 As shown, the present invention mainly includes a box body 1, a bottom plate 3, an upper plate 4, a marking unit and a number plate 5, and the present invention will be described in detail below in conjunction with the accompanying drawings.
[0030] like Figure 1 to Figure 3 As shown, the box body 1 is a rectangular parallelepiped structure and is arranged obliquely. The right end of the box body is high and the left end is low. Inside the box body, a raceway 11 and a conveying path 12 arranged up and down are arranged, and the two are independent of each other. A chute 13 is arranged between the raceway and the conveying way, and the raceway and the conveying way are connected together through the chute, the raceway is a rectangle, and an acute angle is formed between the raceway and the horizontal plane; the distance between the conveying way and the horizontal plane There is also an acute angle between them. The top of the box body is ...
