[0073] The working process of the embodiment is as follows:

[0074] The power supply device transmits power to the power input transmission wheel 112 and the small elevator driving shaft first transmission wheel 211 through the transmission system; the power input transmission wheel 112 provides power for the small elevator, realizing the conveying function of the small elevator. The power input transmission wheel 112 drives the first power output transmission wheel 121, the second power output transmission shaft 131, the first ear picking roller 410 and the second ear picking roller 420 to rotate respectively, and the rotation of the first ear picking roller 410 and the second ear picking roller 420 realizes the ear picking function. The first power output transmission wheel 121 transmits power to the small elevator driven inner shaft first transmission wheel 223, the first ear picking roller 410 and the second ear picking roller 420 in turn, and the first ear picking roller 410 and the second ear picking roller 420 drive the first ear picking chain 313 to work.

[0075] When the ear picking chain is stuck and cannot rotate normally, the small elevator driving shaft 210 rotates normally, and the small elevator driven outer shaft 222 is driven to rotate by the conveying belt 230, ensuring the normal work of the small elevator 200. Since the safety device is provided in the ear picking box 100, the safety device is prior art and will not be described in detail here, so the ear picking box 100 will not be damaged. At this time, the small elevator driving shaft 210, the small elevator driven outer shaft 222 and the conveying belt 230 are not affected and can still rotate normally, so that the "burning belt" phenomenon can be avoided.

[0076] Example 2

[0077] As shown in the description Figure 11 The difference between this embodiment and the embodiment is that the small elevator driven shaft 220 is provided as an integral shaft, not as a nested structure, that is, the small elevator driving shaft 210 and the small elevator driven shaft 220 are connected by the conveying belt 230, and the first ear picking assembly first transmission wheel 311 is directly connected with the first power output transmission wheel 122 of the ear picking box 100 through the belt or chain transmission.

[0078] The difference between the embodiment and the working process of the embodiment is as follows: the power is transmitted to the first driving wheel 311 of the first driving assembly through the belt or chain, the first driving assembly first driving wheel 311 drives the first driving assembly 310 to work, at this time, even if the driving chain is stuck by crops, causing the first driving assembly 310 to stop working, the first driving shaft 121 stops rotating, and the small elevator driving shaft 210, the small elevator driven shaft 220 and the conveying belt 230 are not affected, so that the "burning belt" phenomenon can be avoided.
