[0002] In modern agriculture, faced with large-scale crop planting, modern machinery is needed to harvest crops. Corn harvesters are an indispensable and important equipment in modern agricultural production. Through advanced technology and design, the efficiency and quality of corn harvesting have been greatly improved, the labor intensity of farmers has been reduced, and significant economic benefits have been brought to agricultural production. In actual operation, the correct use and maintenance of these equipment are crucial to improving corn yield and quality.

[0003] Among them, the vertical header corn harvester is an indispensable agricultural machinery in the process of harvesting corn. The vertical header corn harvester is divided into a harvesting part and a driving part. The harvesting part is installed in front of the driving part for harvesting corn, and the driving part is used to drive the harvesting part to move and store the collected corn. When harvesting corn, the harvesting part on the vertical header corn harvester gathers multiple corns and then moves the corn stalks.

DETAILED DESCRIPTION

[0016] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figure 1 to Figure 6 As shown, this embodiment proposes a vertical header corn harvester, including a header frame 1, a header base 2, a stem collecting mechanism, a corn harvesting mechanism, a peeling mechanism and a folding mechanism. The header frame 1 is fixedly installed on the driving part, the header base 2 is fixedly set on the header frame 1, a plurality of stem collecting mechanisms are provided, and the plurality of stem collecting mechanisms are fixedly set on the header base 2. The stem collecting mechanism is used to drive the corn stems to move. A plurality of corn harvesting mechanisms are provided, and the plurality of corn harvesting mechanisms are fixedly set on the header base 2. The corn harvesting mechanism is fixedly set above the stem collecting mechanism. The corn harvesting mechanism is used to separate the corn from the corn stem when the stem collecting mechanism drives the corn stem to move. The corn harvesting mechanism includes a collecting channel 3, and the collecting channel 3 is fixedly set on the header. On the platform base 2, a collecting channel 3 is arranged between two stalk collecting mechanisms, a plurality of peeling mechanisms are arranged, and the peeling mechanisms correspond to the collecting channels 3 one by one. The peeling mechanism is fixedly arranged on the header base 2, and the peeling mechanism is used to peel the corn harvested by the corn harvesting mechanism. The gathering mechanism is fixedly arranged on the header base 2 on a side away from the corn harvesting mechanism, and the gathering mechanism is used to gather the corn stems into the stalk collecting mechanism. When the corn is harvested, the corn stems are driven by the stalk collecting mechanism to move, the corn enters the corn harvesting mechanism and is twisted and falls, and then the corn is collected to the peeling mechanism through the collecting channel 3, and the corn is peeled by the peeling mechanism, which prevents the corn from contacting the stalk collecting mechanism and reduces the possibility of the corn kernels being squeezed and driven away.

[0018] like Figure 1~Figure 2As shown, a corn conveying cylinder 4 and a separating cone 6 are provided on the cutting platform base 2. The corn conveying cylinder 4 is fixedly arranged on the cutting platform base 2. A conveying blade 5 is rotatably arranged in the corn conveying cylinder 4. A plurality of separating cones 6 are provided. The plurality of separating cones 6 are respectively arranged on both sides of the stalk collecting mechanism. A motor for driving the conveying blade 5 to rotate is provided on the cutting platform base 2. The corn peeled by the peeling mechanism is conveyed into the corn conveying cylinder 4, and is conveyed by the conveying blade 5 to the through hole in the center of the corn conveying cylinder 4 and to the driving part.

[0019] like Figure 1 to Figure 6 As shown, the folding mechanism includes a pushing bin 7, a driving cylinder 8, a sliding rod 9 and a pushing plate 10. The pushing bin 7 is fixedly arranged on the header base 2. Two driving cylinders 8 are provided. The two driving cylinders 8 are rotatably arranged on both sides of the pushing bin 7 respectively. The sliding rod 9 is fixedly arranged in the pushing bin 7. Two pushing plates 10 are provided. The two pushing plates 10 are both slidably arranged on the sliding rod 9. The output ends of the two driving cylinders 8 are rotatably connected to the two pushing plates 10 respectively. The two pushing plates 10 in the pushing bin 7 both perform reciprocating motion.

When the planting position of the corn is not aligned with the two traction belts 12, if the corn stem is transported to the threaded cone 14 only by separating the cone 6 and the traction belt 12, the corn stem may be tilted because it is connected to the ground before being cut, causing the corn to tilt to the outside of the corn harvesting mechanism, making the corn difficult to harvest. The push plate 10 pushes the bottom of the corn stem close to the ground so that the root of the corn stem is offset toward the center of the two traction belts 12, which is conducive to the corn entering between the torsion frame 15 and the torsion frame 2 16, thereby avoiding the loss of corn.

[0020] like Figure 1 to Figure 6As shown, the rod-retracting mechanism includes a driving assembly, a tensioning wheel 11, a traction belt 12, a motor 13 and a threaded cone 14.

In this embodiment, the threaded cone 14 and the tensioning wheel 11 can also be driven to rotate by other transmission methods. For example, the threaded cone 14 and the tensioning wheel 11 can be driven to rotate by the internal combustion engine in the driving part. A threaded texture is arranged on the threaded cone 14. When the threaded cone 14 rotates, the corn stems are pulled downward. At the same time, the threaded texture will also cut and crush the corn stems. When the tensioning wheel 11 rotates to drive the tensioning belt to move, the paddle drives the threaded cone 14 of the corn stem town to move.

[0021] like Figure 4~Figure 5 As shown, the corn harvesting mechanism also includes a torsion assembly, and two torsion assemblies are provided. The two torsion assemblies are respectively fixedly arranged on both sides of the collecting channel 3, and the two torsion assemblies are arranged oppositely. The torsion assembly is arranged above the threaded cone 14, and the torsion assembly is used to twist the corn on the corn stem. The torsion assembly includes a torsion frame 15, a torsion frame 2 16, a support wheel 17, a motor 2 18, a motor 3 19, a torsion belt 1 20 and a torsion belt 2 21. The torsion frame 15 is fixedly arranged on the side of the collecting channel 3 away from the peeling mechanism, and the torsion frame 2 16 is fixedly arranged on the side of the collecting channel 3 close to the peeling mechanism.

[0022] like Figure 4~Figure 5As shown, the torsion frame 15 and the torsion frame 2 16 are both inclined, the gap between the torsion frame 15 and the torsion frame 2 16 is aligned with the gap between the two threaded cones 14, and a gathering plate 22 is provided on the torsion frame 15 and the torsion frame 2 16 on the side close to the separation cone 6.

The torsion frame 15 and the torsion frame 2 16 are inclined oppositely, and the corn stalks and corn are gathered between the torsion frame 15 and the torsion frame 2 16 by the gathering plate 22. The corn contacts with the torsion belt 1 20 and the torsion belt 2 21 through the gap between the torsion frame 15 and the torsion frame 2 16. Since the movement speeds of the torsion belt frame 1 and the torsion belt 2 are different, when the corn contacts with the torsion belt 1 20 and the torsion belt 2 21, the corn remains in a vertical state due to the connection with the corn stem. The corn will rotate and the corn will be twisted and fall off on the corn stem. The corn kernels are not hit or crushed. After falling off, the corn will be driven by the torsion belt 1 20 and the torsion belt 2 21 to move toward the collecting channel 3, and then fall onto the peeling roller 23 through the corn drop port 25.
