Problems solved by technology

However, the adaptability of this model to different corn varieties and moisture content has been greatly limited due to the inability to adjust the gap between the vertical ear picking rollers for a long time. For example, the diameter of corn in Huanghuaihai area is only 20-25mm, while the diameter of corn in Northeast China reaches 40mm. Therefore, it is easy to be blocked or broken during the harvesting process, which seriously affects the reliability of the machine and the realization of cross-regional operations, which in turn affects the popularization and application of the machine.

[0031] The active picking roller 4 is sleeved on the driving shaft 5 through a spline, the short stem pulling roller 7 is installed on the bottom o...

Embodiment 2

[0034] Such as figure 2 , image 3 , Figure 4 and Figure 5 As shown, this embodiment is an embodiment further improved on the basis of Embodiment 1, and at the same time, a further detailed description of the present invention is made.

[0035] Such as figure 2 and image 3 , the short stem roller 7 includes a short cone 21, an upper cone seat 22, a lower cone seat 24 and a rib 23, and the short cone 21 is an inner hollow structure with a large diameter at the top and a small diameter at the bottom, so The ribs 23 are uniformly welded on the outer surface of the short cone 21, the upper cone seat 22 is welded in the inner cavity at the top of the short cone 21, and the lower cone seat 24 is welded on the short cone. In the inner cavity of the lower part of the cone 21; 4 to 6 ribs 23 are provided;

[0036]Described long stem roll 14 comprises a long cone upper seat 27, a long cone 26, a straight convex edge 25 and a lower cone seat 24, and the long cone 26 is a hollo...

Embodiment 3

[0039] This embodiment is another structure of the gap-adjustable vertical corn ear-picking device of the present invention, which is adjusted by passive ear-picking roller gaps, and at the same time further describes the present invention in detail.

[0040] Such as Figure 6 As shown, the long stem-drawing roller 14 is arranged on the bottom of the passive ear picking roller 13, the connecting shaft 15 runs through the long stem-drawing roller 14, and the connecting shaft 15 passes through the length of the frame 9. The slotted hole is installed on the self-aligning bearing 29 on the adjustable bearing seat 28, and the threaded rod of the adjustable bearing seat 28 is fixed on the positioning seat 19 by the two adjusting nuts 20.

[0041] In the present embodiment, the connecting shaft 15 in the passive ear picking roller 13 passes through the slotted hole of the frame 9 and is directly installed on the self-aligning bearing 29 on the adjustable bearing seat 28, and is not p...

Abstract

The invention discloses an interval-adjustable standing corncob-picking device. The device comprises a driving corncob-picking roller and a driven corncob-picking roller, a driving shaft, a main stalk pulled roller base, an upper cardan joint locating shaft, an upper cardan joint transmission shaft, a long stalk pulled roller, a short stalk pulled roller, a connecting shaft, a lower cardan joint conveying shaft base, a lower cardan joint locating shaft and an adjustable shaft base; the driving corncob-picking roller is located on the upper part of the driving shaft, the short stalk pulled roller is located on the lower part of the driving shaft, the upper part of the driven corncob-picking roller is installed on the upper cardan joint conveying shaft, the lower part of the driven corbcob-picking roller is connected to the long stalk pulled roller and a bearing base in the lower cardan joint conveying shaft base, the upper part of the lower cardan joint locating shaft is hinged to the lower cardan joint conveying shaft base through a pin shaft, the lower part of the lower cardan joint locating shaft is fixed in the adjustable shaft base after passing through a long groove hole in a rack, and an adjustable bearing base is fixed to a locating base through two adjusting nuts on a threaded rod. The structural interval is convenient to adjust, and it is beneficial for the structure to improve applicability of the interval-adjustable standing corncob-picking device.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a vertical corn ear picking device with adjustable clearance. Background technique [0002] As the core component of the vertical header corn harvester, the vertical corn ear picking device has a simple structure, light weight, low power consumption, and less damage to the ears during the operation process, so this model is a vertical and horizontal roller corn harvester an important addition to . However, the adaptability of this model to different corn varieties and moisture content has been greatly limited due to the inability to adjust the gap between the vertical ear picking rollers for a long time. For example, the diameter of corn in Huanghuaihai area is only 20-25mm, while the diameter of corn in Northeast China reaches 40mm. It is so big that blockage or broken stems are prone to occur in the harvesting process, which seriously affects the reliability of ...
