As shown in fig. 2-4, the transmission system includes a main transmission shaft 3.1, the output wheel of the engine 2 is in transmission connection with the main transmission shaft 3.1 mounted on the frame through a belt or a chain, and the main transmission shaft 3.1 is used for transmitting power to the cutting platform, the peeling machine, the large elevator, the field returning machine and other devices.

The header main shaft output wheel I is arranged on the main transmission shaft 3.1 and is in transmission connection with a header main shaft input wheel on the header main shaft 3.4 through a belt or a chain so as to drive the header main shaft 3.4 to rotate. Be provided with header main shaft output wheel one on header main shaft 3.4, header main shaft output wheel one is connected through belt or chain and the transmission of a jackshaft input wheel on jackshaft 3.5 to drive jackshaft 3.5 and rotate, jackshaft 3.5 one end is connected in order to drive throws the forced draught blower work with throwing forced draught blower transmission. The first intermediate shaft 3.5 is also provided with a first intermediate shaft output wheel, and the first intermediate shaft output wheel is in transmission connection with a second intermediate shaft input wheel on the second intermediate shaft 3.6 through a belt or a chain so as to drive the second intermediate shaft 3.6 to rotate. And a second intermediate shaft output wheel is further arranged on the second intermediate shaft 3.6 and is in transmission connection with a small elevator driving shaft input wheel on the small elevator driving shaft 1.3 through a chain so as to drive the small elevator driving shaft 1.3 to rotate, further drive the small elevator conveying chain 1.2 to rotate, and lift and convey the fruit clusters picked by the picking roller to the transverse auger 5. And a small elevator driving shaft output wheel is also arranged on the small elevator driving shaft 1.3 and is in transmission connection with a driving wheel 5.1 of the transverse packing auger 5 through a belt or a chain so as to drive the transverse packing auger 5 to rotate, and then the clusters are pushed to an inlet of the large elevator 4.

Further, the other side of the header main shaft 3.4 is provided with a header main shaft output wheel II, and the header main shaft output wheel II adopts the same structure to drive the small elevator 1 and the transverse auger 5 on the side.

And a second total-moving-shaft output wheel is further arranged on the total transmission shaft 3.1 and is in transmission connection with a main shaft input wheel of the peeling machine on the main shaft 3.2 of the peeling machine through a belt or a chain so as to drive the main shaft 3.2 of the peeling machine to rotate. The main shaft 3.2 of the peeling machine is used for transmitting power to devices such as the peeling machine, the sheet jelly machine and the large elevator. And the main shaft 3.2 of the peeling machine is also provided with a main shaft output wheel of the peeling machine, and the main shaft output wheel of the peeling machine is in transmission connection with an intermediate shaft input wheel on the intermediate shaft III 3.3 through a belt or a chain so as to drive the intermediate shaft III 3.3 to rotate. And a third intermediate shaft output wheel is further arranged on the third intermediate shaft 3.3 and is in transmission connection with a large elevator driving shaft input wheel 4.32 arranged on the large elevator driving shaft 4.3 through a belt or a chain so as to drive the large elevator driving shaft 4.3 to rotate. The large elevator driving shaft 4.3 drives the large elevator conveying chain 4.2 to rotate through a large elevator driving chain wheel 4.31 arranged on the large elevator driving shaft so as to convey the fruit ears upwards to the peeling machine.

The fruit cluster lifting system and the harvester thereof provided by the invention have the specific working processes that: the engine 2 sequentially drives a main transmission shaft 3.1, a header main shaft 3.4, a first intermediate shaft 3.5, a second intermediate shaft 3.6, a small elevator driving shaft 1.3 and a transverse auger 5 to rotate through a belt or a chain, so that the small elevator conveying chain 1.2 is driven to rotate to lift and convey the clusters picked by the cluster picking roller to the transverse auger 5, and the clusters are pushed to an inlet of the large elevator through the transverse auger 5. Meanwhile, the main transmission shaft 3.1 drives the main shaft 3.2 of the peeling machine, the middle shaft three 3.3 and the big elevator driving shaft 4.3 to rotate in sequence, and then the clusters are lifted and transported to the peeling machine for processing for the second time.
