[0061] In the corn harvester header of the present invention, the small elevator 200 includes a small elevator driving shaft 210, a small elevator driven shaft 220 and a conveyor belt 230, and the small elevator driving shaft 210 and the small elevator driven shaft 220 are connected by transmission through the conveyor belt 230.

More preferably, the small elevator driving shaft 210 is also provided with a small elevator driving shaft second transmission wheel 212, which is connected to the auger to provide power for the auger.

[0063] The driven shaft 220 of the small elevator includes a driven inner shaft 221 and a driven outer shaft 222 of the small elevator; the driven outer shaft 222 of the small elevator is sleeved outside the driven inner shaft 221 of the small elevator and is rotatably connected with the driven inner shaft 221 of the small elevator.

[0064] Preferably, the driven inner shaft 221 of the small elevator is provided with a first transmission wheel 223 of the driven inner shaft of the small elevator and a second transmission wheel 224 of the driven inner shaft of the small elevator; the first transmission wheel 223 of the driven inner shaft and the second transmission wheel 224 of the driven inner shaft of the small elevator are coaxially driven. The first transmission wheel 223 of the driven inner shaft of the small elevator is connected to the first power output part 120 through a belt or a chain; the second transmission wheel 224 of the driven inner shaft of the small elevator is connected to the first reed assembly 310 through a belt or a chain.

[0065] In the straw-pulling assembly 300, the first straw-pulling assembly 310 includes a first transmission wheel 311 of the first straw-pulling assembly, a second transmission wheel 312 of the first straw-pulling assembly, and a first straw-pulling chain 313; wherein the first straw-pulling chain 313 is sleeved on the second transmission wheel 312 of the first straw-pulling assembly; the first transmission wheel 311 of the first straw-pulling assembly drives the second transmission wheel 312 of the first straw-pulling assembly to rotate, and the second transmission wheel 312 of the first straw-pulling assembly drives the first straw-pulling chain 313 to work. The second straw-pulling assembly 320 includes a first transmission wheel 321 of the second straw-pulling assembly, a second transmission wheel 322 of the second straw-pulling assembly, and a second straw-pulling chain 323; wherein the second straw-pulling chain 323 is sleeved on the second transmission wheel 322 of the second straw-pulling assembly; the first transmission wheel 321 of the second straw-pulling assembly drives the second transmission wheel 322 of the second straw-pulling assembly to rotate, and the second transmission wheel 322 of the second straw-pulling assembly drives the second straw-pulling chain 323 to work. A reed-pulling gap is formed between the first reed-pulling chain and the second reed-pulling chain for crops to enter, and the first reed-pulling chain and the second reed-pulling chain cooperate with each other to complete the reed-pulling operation.

[0066] The first transmission wheel 223 of the driven inner shaft of the small elevator is connected to the first power output part 120 through a belt or a chain; preferably, the first transmission wheel 223 of the driven inner shaft of the small elevator is connected to the first power output transmission wheel 121 of the first power output part 120 through a belt or a chain.

[0068] For the first reed-moving assembly 310 in the reed-moving assembly 300, the power input part 110 is connected to the first power output transmission wheel 121 through the transmission shaft 111, and the first power output transmission wheel 121, the first transmission wheel 223 of the driven inner shaft of the small elevator, the first transmission wheel 311 of the first reed-moving assembly, and the second transmission wheel 312 of the first reed-moving assembly are connected in sequence.

[0069] For the second reel assembly 320 in the reel assembly 300 , the power input part 110 , the second power output transmission shaft 131 , the second reel assembly first transmission wheel 321 , and the second reel assembly second transmission wheel 322 are sequentially connected in transmission.

[0070] The working process of this embodiment is as follows:

[0071] The power supply device transmits power to the power input transmission wheel 112 and the first transmission wheel 211 of the driving shaft of the small elevator through the transmission system; the power input transmission wheel 112 drives the driven outer shaft 222 of the small elevator to rotate through the conveyor belt 230 to realize 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 first ear picking roller 410 and the second ear picking roller 420 rotate to realize the ear picking function. The first power output transmission wheel 121 transmits power to the first transmission wheel 223 of the driven inner shaft of the small elevator, the first transmission wheel 311 of the first straw-moving assembly and the second transmission wheel 312 of the first straw-moving assembly in sequence. The second transmission wheel 312 of the first straw-moving assembly drives the first straw-moving chain 313 to work. The second power output transmission shaft 131 transmits power to the first transmission wheel 321 of the second straw-moving assembly and the second transmission wheel 322 of the second straw-moving assembly in sequence. The second transmission wheel 322 of the second straw-moving assembly drives the second straw-moving chain 323 to work. A straw-moving gap is formed between the first straw-moving chain 313 and the second straw-moving chain 323 for easy entry of crops. The first straw-moving chain 313 and the second straw-moving chain 323 cooperate with each other to complete the straw-moving operation.

[0072] Since the driven inner shaft 221 of the small elevator is installed in the driven outer shaft 222 of the small elevator in a nested form, the driven inner shaft 221 and the driven outer shaft 222 of the small elevator do not interfere with each other when they rotate. When the grain-moving chain is stuck and cannot rotate normally, the driving shaft 210 of the small elevator operates normally, and the driven outer shaft 222 of the small elevator is driven to rotate through the conveyor belt 230, thereby ensuring the normal operation of the small elevator 200. Since a safety device is provided inside the ear-picking box 100, the safety device is a prior art and will not be described in detail here, the ear-picking box 100 will not be damaged. At this time, the driving shaft 210 of the small elevator, the driven outer shaft 222 of the small elevator and the conveyor belt 230 are not affected and can still operate normally. Therefore, the "belt burning" phenomenon can be avoided.

[0073] Example 2

[0074] As the instruction manual Fig.11 As shown, the difference between this embodiment and the embodiment is that the driven shaft 220 of the small elevator is arranged as an integrated rotating shaft, and is not arranged as a nested structure, that is, the driving shaft 210 of the small elevator and the driven shaft 220 of the small elevator are connected by a conveyor belt 230, and the first transmission wheel 311 of the first straw-picking assembly is directly connected to the first power output transmission wheel 122 of the ear picking box 100 by a belt or chain transmission.

[0075] The differences between this embodiment and the working process of the embodiment are as follows: power is transmitted from the first power output transmission wheel 122 to the first transmission wheel 311 of the first straw plowing assembly via a belt or chain, and the first transmission wheel 311 of the first straw plowing assembly drives the first straw plowing assembly 310 to work. At this time, even if the straw plowing chain is stuck by the crop, causing the first straw plowing assembly 310 to stop working and the first power output shaft 121 stops rotating, the small elevator driving shaft 210, the small elevator driven shaft 220 and the conveyor belt 230 are not affected, so the "belt burning" phenomenon can be avoided.
