Technical Field

The invention relates to a plate feeding device for fixing a cotton picking roller of a cotton picker, in particular to a plate feeding structure of a spindle picking system capable of realizing multi-axis rotation.

Background

One of the cotton pickers currently used in China is an American horizontal spindle cotton picker, the spindle rotating speed is high, the requirements on materials and stability are high, and the localization difficulty is high; the other cotton picker is an old soviet union type vertical spindle cotton picker, the spindle rotating speed is low, the requirements on materials and stability are low, but the picking rate is low, the spindle of the vertical spindle cotton picker is long, a vertical spindle shaft is easy to deviate in the working process, and the free end of the spindle is easy to swing due to the fact that the vertical spindle shaft is installed in a cantilever mode, a cotton picking roller and the vertical spindle are prone to wear mutually, and a cotton picking head is prone to failure and invalidation.

Disclosure of Invention

In order to solve the technical problems, the invention provides a novel porous rotary upper plate which not only can solve the deviation of a vertical spindle shaft, but also can effectively reduce expensive use and maintenance cost caused by damage of a picking head and the like.

The technical scheme adopted by the invention for solving the technical problems is as follows: a porous rotating upper disc consists of a disc and a sleeve. The edge evenly distributed of disc bottom has 12U type holes, and top edge evenly distributed has 12 semicircle type holes to U type hole and semicircle type hole form the shoulder hole in same position, and the shoulder hole on the disc is with spindle shaft interference fit and pass through screw hole thread tightening. The edge of the disc is uniformly provided with 12 threaded holes which are positioned between every two stepped holes, the stepped holes on the disc are in interference fit with the spindle shaft and are fixed by the threaded holes, the sleeve is positioned in the center of the upper disc and protrudes out of the disc from top to bottom, the inner side of a main hole in the center of the sleeve is provided with a key groove, and the main hole is in interference fit with the spindle shaft and is positioned and driven by a key. When the cotton picker is operated, the upper disc rotates around the main hole along with the rotation of the main shaft, and simultaneously drives the spindle shaft connected with the upper disc to rotate, so that the aim of preventing the vertical spindle shaft from deviating seriously is fulfilled.

Compared with the prior art, the invention has the beneficial effects that: (1) the device has simple structure and convenient assembly and disassembly, (2) the upper disc rotates by taking the main hole as the center and drives the spindle shaft connected with the upper disc to rotate, thereby preventing the vertical spindle shaft from deviating seriously; (3) the flexible spindle cotton picking rotor is convenient to replace and maintain, and the maintenance cost is reduced. (4) Energy saving and low manufacturing cost.

Drawings

The invention is further illustrated with reference to the following figures and examples.

FIG. 1 is a schematic view of a perforated rotating upper disk of the present invention.

Fig. 2 is a schematic cross-sectional view of fig. 1.

In the figure: 1-disc, 2-cylinder, 3-threaded hole, 4-U-shaped hole, 5-semicircular hole, 6-main hole and 7-key groove.

Detailed Description

In the embodiment shown in fig. 1 and 2, the invention is a porous rotating upper disk structure which comprises a porous rotating upper disk consisting of a disk (1) and a cylinder (2). Disc (1) bottom edge evenly distributed has 12U type hole (4), and top edge evenly distributed has 12 semicircle type hole (5) to U type hole (4) and semicircle type hole (5) form the shoulder hole in same position, and the shoulder hole on disc (1) and spindle shaft interference fit are through screw hole (3) thread tightening. Disc (1) edge evenly distributed has 12 screw hole (3), and it is located between per two shoulder holes, shoulder hole and the spindle interference fit on disc (1) and pass through screw hole (3) thread tightening, and drum (2) are located the hanging wall center and than disc (1) protrusion from top to bottom, and drum (2) center is equipped with main opening (6), and the inboard has keyway (7), and main opening (6) and spindle interference fit are fixed a position and are driven through the key with the spindle.

When the cotton picker operates, the torque generated by the driving force is transmitted to the upper disc by the spindle through the key in the key groove (7) on the inner side of the main hole (6), so that the upper disc rotates by taking the main hole (6) as the center and drives the spindle shaft assembled on the stepped hole to rotate, thereby being beneficial to the working stability of the spindle shaft and achieving the purpose of preventing the vertical spindle shaft from deviating seriously.
