[0042] In some embodiments, the corn ear collecting device further includes a driving component 10, which is connected to the first roller 2 for driving the first roller 2 to rotate.

[0043] Specifically, such as Figure 1 As shown, the drive component 10 includes a driver 101, a chain 102, and a driven sprocket 103. The driver 101 is fixed on the housing 100, the driven sprocket 103 is mounted on the first roller 2, a drive sprocket is mounted on the output shaft of the driver 101, and the driven sprocket 103 is mounted on the first roller 2.

[0046] The following is combined Figure 1 and Figure 2 The operation process of the corn ear collecting device according to an embodiment of the present invention is described.

[0047] Before harvesting, the buffer belt 1 is mostly wound on the first reel, and the horizontal section 11 of the buffer belt 1 is in the first position. It should be noted that the first position is the highest position of the buffer belt 1 inside the box 100.

[0048] When harvesting, the corn ears fall into the box 100 and fall on the buffer belt 1, and as the number of the corn ears increases, the buffer belt 1 wound on the first winding roller 2 is gradually unwound by rotating the driving device 101 in the cab, and the collected corn ears are gradually sent to the bottom of the ear box at a gentle speed above the conveying belt, so as to reduce the impact between the corn ears and the box 100. After the box 100 is filled, the box 100 is unloaded along the inclined surface on the left side of the box 100, and at the same time, the buffer belt 1 is re-wound on the first winding roller 2 by reversing the rotation of the driving device 101, and since the volume of the accommodating cavity is reduced, the rapid unloading can be realized, and the phenomenon that a few corn ears are left on the bottom of the box and unloading is not complete is avoided. After the corn ears are poured out, the above operation is repeated, and the next round of collection process can be directly entered.
