[0027] The pair of picking rollers 103 are driven to rotate by the transmission device 4. The worm gear drives the worm wheel connected to it to rotate, which in turn drives the reeling wheel 104 above the worm gear to rotate. During the picking operation, the corn stalks are moved by the reeling wheel 104 and fed into the space between the two picking rollers along with the guide plate 105. The picking rollers are driven to rotate by the transmission device 4, causing the corn on the corn stalks to fall off and into the cargo box 2 located on the left side of the picking device 1, completing the corn stalk picking and boxing operation. The upper retaining frame 102 is to prevent the fed corn stalks from falling over.

[0028] Furthermore, such as Figure 4 As shown, the cargo box 2 is welded to the left side of the cover plate 101 of the ear-picking device 1.

[0030] Furthermore, such as Figure 5 As shown, the straw crushing device 3 is welded to the cover plate 101 of the ear-picking device 1 and is located below the ear-picking device 1. The straw crushing device 3 includes a shovel 301, a blade shaft 302, a blade shaft welding plate 303, and a shovel mounting plate 304.

The driven pulley receives the rotational speed transmitted from the transmission device 4 and drives the shovel 301 to rotate.

[0031] The driven wheel on the left side of the blade mounting plate 304 drives the blade 301 to rotate, thereby crushing the corn stalks after ear picking.

[0032] Furthermore, such as Figure 6 As shown, the transmission device 4 includes a gearbox 401, a transmission pulley 402, and a gearbox mounting plate 403; wherein the gearbox 401 is fixed on the gearbox mounting plate 403, the transmission pulley 402 is connected to the gearbox 401 by a shaft hole, and the gearbox mounting plate 403 is welded to the blade mounting plate 304 of the straw crushing device 3.

[0033] The transmission device 4 is located behind the ear-picking device 1 and is fixed to the straw-crushing device 3 by welding. It includes a gearbox 401, a transmission pulley 402, and a gearbox mounting plate 403. The transmission pulley 402 is connected to the gearbox 401 by a shaft hole. The gears inside the gearbox 401 mesh to drive the movement of each device. First, the transmission pulley 402 drives the drive wheel to rotate, which in turn drives the driven wheel installed on the outside of the straw crushing device to rotate. Second, it drives the worm gear inside the right ear-picking roller 103 to rotate, which in turn drives the turbine below the reel 104 to rotate.

[0034] Furthermore, such as Figure 7 As shown, the drive device 5 is fixed to the mounting plate by bolts; the drive device 5 is located on the right side of the gearbox 401; the drive device 5 includes an intelligent motor 501, a reducer 502 and a motor bracket 503; the intelligent motor 501 and the reducer 502 are connected by an interference fit and then fixed to the motor bracket 503 by bolts.

The output shaft of the reducer 502 is connected to the gearbox 401 through the coupling; the motor bracket 503 is welded to the blade mounting plate 304 of the straw crushing device 3.

[0035] Specifically, the reducer 502 is a proportional reducer; the drive device 5 is located on the right side of the transmission assembly 4, the intelligent motor 501 is reversed through the proportional reducer 502, and then connected to the transmission device 4 through a coupling. After the intelligent motor 501 and the reducer 502 are connected, they are fixed to the mounting plate with bolts. Reinforcing ribs are added to both sides of the mounting plate to further strengthen the structure.

[0036] The intelligent motor 501 is a brushless motor. The brushless motor achieves precise torque output through intelligent algorithms. When the output torque is insufficient to support the movement of the machine, the motor will automatically stop to prevent motor damage and bending caused by insufficient strength of the output shaft.

In addition, by driving the harvesting cutter with a motor, the problem of slow response speed and low efficiency of traditional harvesting cutters is solved.
