Description

Technical Field

[0001] This utility model belongs to the technical field of corn picking sticks, and specifically relates to a corn picking stick structure that does not break kernels. The picking stick structure of this utility model can be used on common picking sticks such as vertical picking sticks and horizontal picking sticks. Background Technology

[0002] The corn picking roller is one of the most important components of a corn harvester, playing a crucial role in the successful harvesting of corn. Currently, there are various structures for corn picking rollers. In terms of the type of ribs, there are spiral ribs, straight ribs, and combinations of both. Spiral ribs have a lower kernel breakage rate but a poorer stalk pulling effect; straight ribs have a better stalk pulling effect but a higher kernel breakage rate.

[0003] While there are existing technologies that combine both methods, they also present certain problems. If the pitch of the spiral ribs is large, it is easy to break the particles, but the resistance is small; conversely, it is not easy to break the particles, but the resistance is large.

[0004] The problem we need to solve is how to avoid both breakage and excessive resistance. Utility Model Content

[0005] This invention provides a corn kernel-removing and ear-picking stick structure that eliminates the need for kernel breaking, which can solve the problems pointed out in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a picking area, the surface of which is provided with a main spiral rib, a straight pull rib and an auxiliary spiral rib, the radius of the main spiral rib is 6-10mm and the pitch is 3-4cm, the radius of the straight pull rib is 3-6mm, and the auxiliary spiral rib is provided at the center between adjacent main spiral ribs, the radius of the auxiliary spiral rib being 3-6mm.

[0007] Preferably, the number of straight tie rods is 4-8.

[0008] Preferably, the height of the auxiliary spiral ribs between adjacent straight tie rods gradually increases along the feeding direction.

[0009] Preferably, the height of the end of the auxiliary spiral rib between adjacent straight tie rods is the same as the height of the straight tie rod.

[0010] Beneficial effects: This utility model provides a corn kernel-breaking picking roller structure. Based on the original main spiral rib, an auxiliary spiral rib is added at the center of the adjacent main spiral rib. The radius of the auxiliary spiral rib is smaller than that of the main spiral rib. This is equivalent to reducing the pitch of the main spiral rib, making the spiral ribs denser, thereby effectively avoiding the occurrence of kernel breakage. Moreover, since the radius of the auxiliary spiral rib is much smaller than that of the main spiral rib, its resistance will not increase too much.

[0011] In other words, we should play to our strengths and avoid our weaknesses, giving full play to our advantages. Attached Figure Description

[0016] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0017] Example 1:

[0018] like Figure 1-2 As shown, a corn kernel-free ear-picking roller structure includes an ear-picking area 1, the surface of which is provided with a main spiral rib 11, a straight pull rib 12 and an auxiliary spiral rib 13. The radius of the main spiral rib 11 is 6-10mm and the pitch is 3-4cm. The radius of the straight pull rib 12 is 3-6mm and the number of straight pull ribs 12 is 4-8. The auxiliary spiral rib 13 is provided at the center between adjacent main spiral ribs 11, and the radius of the auxiliary spiral rib 13 is 3-6mm.

[0019] In some embodiments, in order to facilitate the guidance of corn ears to the straight tie rod 12 for ear picking, the auxiliary spiral ribs 13 between adjacent straight tie rods 12 gradually increase in height along the feeding direction. This structure can also reduce resistance to a certain extent. The end height of the auxiliary spiral ribs 13 between adjacent straight tie rods 12 should be consistent with the height of the straight tie rod 12. A section of steel bar can be cut along its diagonal direction to obtain two sections of auxiliary spiral rib 13 raw material, which can achieve the gradual increase in rib height. After spiral processing, welding can be completed.

[0020] This invention can be applied to common ear-picking sticks such as vertical and horizontal ear-picking sticks. By designing the ear-picking area (ear-picking section) of the vertical or horizontal ear-picking stick into the above-mentioned structural form, the above-mentioned technical problems can be solved.

[0021] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
