When there is a gap between the first cylinder 3011 and the inner wall of the side plate 101 on the left, the first end agitator 301 is half-surrounded by the connecting assembly on the left.

The distance between the axis of the auger shaft 601 and the auger bottom plate 7 is set to R5, satisfying: R5>R1. At the same time, it is required that the gap between the bottom of the first cylinder 3011 or the second cylinder 3021 of the end auger and the auger bottom plate 7 is greater than the diameter of a maximum-sized fruit ear, so that the fruit ear can pass smoothly, so that even if the maximum-sized fruit ear material passes through the auger feed port, it will not cause blockage, and the fruit ear will not cause blockage when passing through the auger discharge port, so as to ensure the smoothness of the fruit ear transportation. During the installation of the end auger 3, the first spiral blade 3013 and the second spiral blade 3023 are required to be in a blade continuous spiral installation state with the main spiral blade 602 (they have the same outer diameter and consistent spiral). The first spiral blade 3013 and the second spiral blade 3023 are respectively connected to the main spiral blade 602 to form a whole, namely the auger blade, which can complete the effective transportation of the fruit clusters.

[0065] It should be noted that the spiral blade of the end auger 3 can not only be a single blade (such as Figure 3 or Figure 8 ), double blades can also be used, such as Fig. 9 As shown, when double blades are used, the double blades also need to be consistent with the spiral direction of the main spiral blade 602 to ensure spiral continuity.

At the same time, the bearing seat mounting seat 2 does not extend beyond the mounting holes, that is, does not extend beyond the outer side of the cutting platform frame 1, so that the width of the cutting platform is not increased.

[0071] The beneficial effects of the technical solution of the utility model are:

In addition, since there is no obstruction in the feeding channel where the fruit ears are transported from the picking device to the auger (i.e., the feeding port of the auger), the fruit ears will not rebound or accumulate, thereby ensuring or improving the conveying efficiency.
