Embodiment 1

[0032] The specific structure of the novel corn picking roller with bionic geometric structure surface structure of this example is given by figure 1 , figure 2 is shown with Figure 3. The new type of corn picking roller in this example has the following structural features: the small-diameter roller surface of the picking roller is distributed with a bionic geometric structure surface structure 6 arranged in a spiral along the axis of the roller shaft and two guiding helical wide ribs 7. The surface structure 6 of the bionic geometric structure in this example adopts a convex hull structure, and the guiding spiral wide rib 7 adopts a spiral wide rib (the width of the rib is 15-20mm). The specific structure is: the convex hull structure distributed on the cylindrical surface of the small-diameter roller of a single ear picking roller is approximately equilateral triangle distribution on the unfolded surface of the cylindrical surface, the convex hull spacing is 12-15mm, and ...

Embodiment 2

[0034] The specific structure of the novel corn picking roller with bionic geometric structure surface structure of this example is given by figure 1 , figure 2 is shown with Figure 3. The novel corn ear picking roller with the bionic geometric structure surface structure described in this example is different from Example 1 in that the bionic geometric structure surface structure 6 of this example is a pit-shaped structure arranged in a spiral along the axis of the roller shaft. The rest are the same as described in Example 1.

Embodiment 3

[0036] The specific structure of the novel corn picking roller with bionic geometric structure surface structure of this example is given by figure 1 , figure 2 is shown with Figure 3. The novel corn picking roller with the bionic geometric structure surface structure described in this example is different from Example 1 and Example 2 in that: the bionic geometric structure surface structure 6 of this example is a convex hull / concave arranged in a spiral shape along the axis of the roller shaft. Pit-type structure, that is, the surface of the ear-picking rollers installed on the higher side is arranged in a spiral shape along the axis of the roller shaft, and the surface of the ear-picking rollers installed on the lower side is arranged in a spiral shape along the axis of the roller shaft. The pit-type structure of the cloth. The rest are the same as described in Example 1.

Abstract

The invention relates to a corn stripper roller with a bionic geometrical structure surface for a corn harvester, belonging to a corn harvesting machinery in agricultural machinery. The invention comprises a pair of corn stripper rollers arranged in symmetry. Each corn stripper roller comprises a guide cone (1) of spiral protruding ridge, a core stripping section (2) of a guide spiral ridge (7), a stem pulling section (3) and a power joint (4). The corn stripper roller is fifty to sixty millimeter in minor diameter. The guide spiral ridge (7) of the core stripping section (2) adopts two protruding ridges which is fifteen to twenty millimeters in width. The slippery cylinder surface of the core stripping section (2) is provided with small units arranged in a spiral shape along the axis of the roller. The invention provides a corn stripper roller with a bionic geometrical structure surface, realizing non-damage corn stripping function of a horizontal roller device and reducing the weight of a roller type corn stripping device.

Description

Technical field: [0001] The invention relates to a horizontal ear picking roller for a corn harvester, which belongs to the corn harvester in agricultural machinery. Background technique: [0002] At present, the most commonly used horizontal ear picking roller for the ear picking device on the corn harvester has a dragon-claw type ear picking hook on the surface and a smooth surface of the ear picking roller. In addition, there are vertical ear picking rollers and plate ear picking methods. The ear picking structure. Due to the complex structure and heavy weight of the vertical ear picking roller structure, there have been few product applications for many years. The plate-type ear-picking structure is mostly used on self-propelled corn harvesters. Its advantage is that it has little damage to the ears of corn. The disadvantage is that the rate of broken stems is high, which increases the failure rate of subsequent processing. Horizontal ear picking rollers are mostly use...
