At the same time, corn straw is also an important feed for animal husbandry. Harvesting corn is an important link in corn production. Therefore, harvesters are needed in the corn harvesting stage. In order to reduce the labor burden of farmers and rationally utilize straw, ear-stalk and stem harvesters are widely used.
[0003] The existing corn harvester for harvesting both ears and stalks is designed with a combination of reed pulling, cutting, ear picking and conveying for processing corn and straw. Structurally, the reed pulling method mainly adopts a reed pulling wheel, and then directly enters the horizontal ear picking roller pair for ear picking. After ear picking, the corn stalks are pulled downward, and the space under the machine is limited, resulting in a complex straw crushing structure and a slow crushing speed. The corn harvest does not match the straw crushing speed, and the straw processing speed is slow.

[0024] In one embodiment, two guide inclined plates 12 are welded to the inner side surface of the port of the straw receiving mouth 2, and the facing ends of the two guide inclined plates 12 are provided with U-shaped notches 13, and the two guide inclined plates 12 are arranged in a trumpet-shaped structure. Two guide rollers 11 are connected to the inside of the straw receiving mouth 2 through an axle seat, and the two guide rollers 11 are distributed on the left side of the guide inclined plates 12. When the straw is transported to the straw receiving mouth 2 after the plowing and cutting processes, the two guide inclined plates 12 and the U-shaped notches 13 at their facing ends guide the straw so that the straw extends between the two guide rollers 11, and the setting of the U-shaped notches 13 makes it easy to peel off the delicate corn ears on the straw, and then the guide rollers 11 and the straw are pushed to the straw crushing box 1 by rolling relative to each other, which facilitates the guiding and crushing of the straw and makes it easy to remove the delicate corn ears, thereby reducing the loss of corn harvesting.
[0025] In one embodiment, the upper cross-section of the straw crushing box 1 is a rectangular structure, and the lower cross-section of the straw crushing box 1 is an arc structure. The straw crushing box 1 with the above structure can easily crush the straw while meeting the straw feeding requirements.

When the straw is conveyed to the straw receiving mouth 2 after the reeding and cutting processes, the two guide inclined plates 12 and the U-shaped notches 13 at the opposite ends thereof guide the straw so that the straw extends between the two guide rollers 11. The setting of the U-shaped notches 13 makes it easy to peel off the delicate corn cobs on the straw. Then, the guide rollers 11 and the straw are pushed to the straw crushing box 1 by rolling relative to each other. The crushing knife shaft 5 fixed to its output end is driven to rotate by starting the motor 4, so that the crushing knife shaft 5 drives a plurality of knife seats 8 equidistantly arranged on its surface to rotate, and then the circular arc blade 9 arranged around each knife seat 8 cuts the straw horizontally pushed by the straw receiving mouth 2. In this process, a plurality of auxiliary cutters 10 welded on both sides of the circular arc blade 9 implement secondary shredding. The crushed straw is discharged into the straw recovery bin of the corn harvester through the discharge mouth 6.
