Description

Technical Field

[0001] The invention relates to a vertical corn stalk leaf and ear removing device. Background Art

[0002] With the development of agricultural machinery technology, mechanized harvesting of crops has been widely adopted. Among them, the emergence of mechanized corn harvesting equipment has realized the linkage of multiple mechanisms to cooperate in large-scale harvesting, thereby greatly improving the efficiency of corn harvesting operations. Corn harvesting equipment in the existing technology usually crushes the straw and returns it to the field, and includes multiple mechanisms such as harvesting mechanism, corn cob conveying mechanism, straw processing mechanism, peeling mechanism, etc., with a cumbersome structure and low harvesting efficiency. In view of the characteristics of harvesting efficiency and crushing and returning to the field of existing corn harvesters, a vertical straw de-leafing and de-earing device is used to complete the ear picking, peeling and backward conveying of straw at one time. Compared with traditional models, it integrates the two processes into one. Vertical harvesting makes the design of corn harvesters more compact and improves the comprehensive application of corn straw in the production industry. Summary of the Invention

[0003] The purpose of the present invention is to address the shortcomings of the existing technology and propose a vertical corn stalk de-leafing and de-earing device. A set of devices can simultaneously de-ear and de-leave corn stalks, saving space, increasing equipment, and increasing corn stalk resource utilization.

[0004] To achieve the above purpose, the present invention adopts the following scheme.

[0005] Furthermore, the vertical corn stalk de-leafing and de-earing device is designed to be 75 degrees to the horizontal plane, and the whole corn cut by the front-end cutting platform is directly poured onto the de-leafing and de-earing roller of the vertical corn stalk de-leafing and de-earing device.

[0006] Furthermore, when the vertical corn straw de-leafing and de-earing device is working, the corn straw de-leafing and de-earing device composed of the main rotating rubber roller and the slave rotating rubber roller will cut off the leaves and ears of the corn straw after being cut off from the root by the friction force of the rubber roller.

[0007] Furthermore, the main rotating rubber roller in the vertical corn straw defoliation and ear removal device has a protruding structure and a segmented design. After the corn straw enters the corn straw defoliation and ear removal device, it is processed in segments according to the growth characteristics of the corn plant, and the corn ears will not be crushed due to excessive squeezing force of the rubber roller.

[0008] Furthermore, after the corn stalk leaves and ears are removed from the corn stalk, the twisted leaves and ears are rotated upward and transported to the top for discharge through the friction force generated by the rotation of the active rubber roller and the driven rubber roller.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] A vertical corn stalk de-leafing and de-earing device comprises a main rotating rubber roller (1), a secondary rotating rubber roller (2), a transmission device (3), and a motor (4). The plane where the main rotating rubber roller (1) is located is inclined at an angle of 75° to the horizontal plane, and the upper end of the main rotating rubber roller (1) and the transmission device (3) are meshed with each other through gears for transmission.

[0017] In this embodiment, the main rotating rubber roller (1) includes a fast leaf-removing section (1-1), a U-shaped ear-picking section (1-2), a U-shaped ear-picking claw (1-3), and a circular gear (1-4). The surface of the fast leaf-removing section (1-1) is covered with a rubber layer with a pattern. The pattern is coarse and can quickly break the skin. The U-shaped ear-picking section (1-2) adopts a straight groove design parallel to the roller axis and a protruding U-shaped ear-picking claw (1-3). The opening direction of the U-shaped ear-picking claw (1-3) structure is the same as the rotation direction of the main rotating rubber roller (1). The opening width of the U-shaped ear-picking claw (1-3) structure is slightly larger than the diameter of the corn cob stalk, which is convenient for twisting off the corn cob.

[0018] In this embodiment, the plane where the slave rotating rubber roller (2) is located is tilted at an angle of 75° to the horizontal plane, and is arranged side by side with the main rotating rubber roller (1). The slave rotating rubber roller (2) and the upper end of the main rotating rubber roller (1) are meshed with each other through gears and rotate in the opposite direction to the main rotating rubber roller (1). The slave rotating rubber roller (2) is in the shape of a large-pitch rubber roller, does not damage the straw, and undertakes the task of transporting the straw and the fruit ears.

[0019] In this embodiment, there is a certain gap between the main rotating rubber roller (1) and the secondary rotating rubber roller (2), and the corn stalks that have been de-leaved and de-eared are transported backward through the gap under the rotation of the main rotating rubber roller.

[0020] In this embodiment, the protrusion of the main rotating rubber roller (1) provides friction and radial transmission torque, and the U-shaped ear-picking claws (1-3) twist the corn ears off at the corn ear stalk.

[0021] In this embodiment, under the action of the rotation of the slave rotating rubber roller (2) and the rotational twisting action of the main rotating rubber roller (1), the corn cob is conveyed to the top under the action of the slave rotating rubber roller (2), and the corn stalks are squeezed out from the gap of the rotating rubber roller.

[0022] In this embodiment, the transmission device (3) includes a motor pulley (3-1), a belt (3-2), a pulley (3-3), a middle gear (3-4), and a middle shaft (3-5). The middle gear (3-4) meshes with the circular gear (1-4) to transmit power.

[0023] In this embodiment, the motor (4) provides power output, and the power output of the motor (4) is connected to the motor pulley (3-1).
