Description

[Detailed explanation of the invention] There is a so-called self-threshing type equipped with an automatic feeding threshing machine, and a normal type (also known as the threshing type) in which the entire harvested grain culm (culm part and ear) is thrown into the handling chamber for threshing. Generally speaking, when working with a conventional combine harvester, the harvested grain culm is simply fed into the handling chamber, so there is no handling at the starting end of the handling barrel. The presence of a protruding spiral auger that actively feeds grain culms into the room is very effective, but on the other hand, when working with a self-shedding type, The presence of the auger is not necessarily effective as it is often caused by
Because it acts rapidly on the grain culms near the entrance of the handling room, a large amount of culm breakage and panicle breakage occurred, resulting in defects that adversely affected subsequent sorting.

The purpose of this invention is to eliminate the defects when working with such a self-removal type.
This problem could be solved by extending the inlet funnel toward the treatment room to completely cover the top of the auger.

The present invention will be described below based on an embodiment shown in the drawings. An auger 3 for feeding grain culm into the handling chamber 1 is protruded from the starting end of a handling barrel 2 that is mounted in the handling chamber 1.
On the lower side of the auger 3, a grain charging passage 5 in which the beater 4 is mounted is connected, and on the upper side, the auger 3 is connected between the front inlet funnel 6 and the starting end of the handling trunk. The upper surface of the cover body 7 and the handling barrel cover 8 constitute a grain culm feeding passage 9 into the handling chamber 1.

Then, on one side of the handling chamber 1, a feed chain 11 with a pinching rail 10 disposed oppositely is connected to the auger 3.
It extends to the front on one side. Reference numeral 12 indicates a receiving net, and reference numeral 13 indicates a sorting section.

Although the drawing is omitted, when working with a self-shedding type, a self-shedding reaping section is attached to the front of the threshing section, and work is done with a normal type (mainly for wheat and rice varieties with good shedding properties). ), replace it with a regular type reaping part.

Therefore, when working as a normal type, the grain culm after harvesting is lifted up by the lifting conveyor, and when it is thrown into the entrance side of the handling room 1 by the beater 4 through the feeding passage 5, the grain culm is The grains are immediately sent into the handling chamber 1 under the action of the auger 3, and are shredded by the handling cylinder 2. On the other hand, when working with a self-shedding type, the grain culms cut in the reaping section are When the feed chain 11 reaches the end of the conveyance, the stock end is inherited by the start end of the feed chain 11 and conveyed rearward while being pinched.
The side part of the ear tip is received on the inlet funnel 6 and is supplied into the handling chamber 1 through the feeding passage 7 on the upper surface of the cover body 7. It is not affected by the action of the auger 3, therefore, the occurrence of culm breakage and panicle breakage can be prevented, and subsequent processing can be maintained well.

Claims (1)

[Scope of utility model registration request] An auger for feeding the grain culm into the handling chamber is protruded from the starting end of the handling barrel that is shaft-mounted in the handling chamber, and a grain culm input passage on which a beater is mounted on the internal shaft is connected to the lower side of the auger. A cover body covering the upper surface of the auger is connected to the upper side between the front inlet funnel and the starting end of the handling barrel, and the upper surface of this cover body is connected to the grain culm feeding passage into the handling chamber. A combine harvester that can be used both as a self-removal type and as a normal type.
