Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention can be used in threshing equipment mounted on combines, etc., especially in axial flow type threshing equipment. It is suitable, and in particular relates to an improved structure of the handling cylinder therein.

0002

[Conventional technology]

Generally, rice, wheat, buckwheat, and legumes are harvested, and the harvested material is transported through an axial flow conveyor-like conveyor. The handling barrel of the so-called general-purpose combine harvester, which carries out the threshing process by lifting and feeding the grain to the molded threshing device, is It consists of a conical shell on the supply port side and a main shell on the inside of the plate chamber, and a band-shaped toothed plate is wound spirally around both.

[Problem that the idea aims to solve]

By the way, crops planted on the ground are harvested by the combine harvester mentioned above and transported on a conveyor. The grain is transported to the threshing equipment by a transporter. At the end of the conveyor, such cuttings are Reaping on the inlet plate that is continuously fed on the inlet plate in the supply port, but without forced conveyance force Objects are scraped by the teeth of a rotating conical barrel and carried around along the spiral guide surface. The grains move to the main trunk side and are threshed.

0004 However, the tooth plate on the conical barrel has the same rotational diameter as that of the main barrel. Therefore, especially at the starting end, the cuttings sent from the conveyor 8 enter the supply port. It often comes into contact with the helical non-guiding surface of the facing tooth plate, and for this reason, the circle of the reaped material Smooth raking was not done, and temporary accumulation occurred, causing a blockage at the inlet. Furthermore, there are problems such as the wind generated by the rotation of the handling cylinder blowing the air out of the aircraft.

[0005] In addition, to avoid this, the receiving surface of the entrance plate may be lowered or the downward slope may be increased. When the mouth is made larger, the harvested material directly above the entrance plate will be shed, and the grains will be affected by the raking action of the tooth plate. Since it cannot be directly affected, it becomes stagnant in this area and is more likely to be blown out of the aircraft. Some have many drawbacks.
