Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention supplies the entire amount of harvested grain culms into a handling room equipped with a handling barrel that rotates around a longitudinal axis of the machine body. This is a combine harvester-type culm-feeding combine that threshes while transferring to the rear.

[Problems to be Solved by Prior Art and Invention]

Generally, in this type of combine, the grain culms that are entirely supplied into the handling chamber are subjected to threshing treatment with the receiving net while being transferred from the supply port side to the discharge port side of the handling chamber by the handling barrel. , The threshed grains, etc. are leaked from the net to the lower swing sorting device, but the threshing culms such as shavings are discharged from the discharge port on the rear side of the handling room (the handling room end side). I try to release it to the outside.

However, in the past, since the discharge port of the handling chamber was exposed above the end side of the rocking sorting device, the culms were dropped onto the rocking sorting device, and therefore, the culms on the rocking sorting device. Was stagnation and deteriorated the sorting performance.

Therefore, in order to eliminate such a problem, an inclined guide plate that is inclined rearward and downward is provided at a portion corresponding to the lower side of the discharge port of the handling chamber to cover the upper end side of the rocking and sorting device and the culm to the rear. There is a technology that makes the guide drop. (See U.S. Pat. No. 4,266,560) According to such a configuration, not only the discharge function of the culms is hindered, but also the sludge guide plate is stagnant and the discharge port is clogged to cause an excessive threshing load. However, there is a problem in that threshing performance and efficiency are reduced.

The present invention has an object to solve such a problem, and has the following technical means.

[Means for Solving the Problems]

That is, the technical means according to the present invention is arranged such that the supply port 16 is provided at the front end side of the handling chamber 13 in which the handling barrel 3 is internally mounted and the whole amount of the grains to be supplied supplied by the handling barrel 3 is rotated. Threshing while transferring axially backward, the threshed grain is net
In addition to letting it leak downward, the threshing culm is configured to be discharged from an outlet 17 provided at the rear end side of the handling chamber, and below the handling chamber 13, grain leaking from the receiving net 14 is provided. An oscillating sorting device 21 for sieving and selecting while receiving and oscillatingly transferring to the rear is provided,
The outlet 17 of the handling chamber is characterized in that it is opened at a position rearward of the end of the swing selecting device 21.

[Action]

When all the cut grain culms from the pre-mowing treatment portion are supplied and supplied into the handling chamber 13, the grain culm is transferred by the handling barrel 3 from the supply port 16 side to the discharge port 17 side while receiving the grain culm. It is threshed by the threshing action with the net 14. The threshed grains and the like are leaked from the receiving net 14 onto the swing sorting device 21 below, and the threshing culms such as shavings are swung sorted from the discharge port 17 on the terminal side of the handling chamber 13. From the end of the device 21, it is quickly discharged rearward and dropped.

〔The invention's effect〕

As described above, according to the present invention, since the culms discharged from the outlet of the handling chamber do not drop on the swing sorting device, the sorting performance can be improved, but the outlet can be handled. Since there is no obstacle such as an inclined guide plate in the lower part, there are almost no problems such as stagnant culm and clogging near the discharge port, and a quick and smooth discharge action can be expected, and threshing performance , Came to be able to improve efficiency.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. On a machine body 2 equipped with a crawler-type traveling device 1, a threshing device 4 equipped with a handling cylinder 3 that rotates around the longitudinal axis of the machine body is mounted, and in front of it a standing culm culm of a field is sown. Divider 5. Reel for scraping slaughtered culms to the rear 6 ・ Mowing device 7 for cutting scraped culms ・ Auger 8 for collecting the stalks after cutting to the center side and sending it backward There is provided a pre-mowing processing unit equipped with a carrier device 9 for inheriting the grain culms sent to the rear side and scraping up and transporting the grain culms to the threshing and transporting unit 4.

In the transporting and feeding 9, a net 11 through which grain can leak is stretched at the bottom between the auger 8 and the beater 10, and a rotor 12 with a plurality of protrusions 12a rotating around the horizontal axis is arranged on the net 11. The grain culm can be picked up and conveyed between the culm and the leakage net 11.

The threshing device 4 is mainly composed of the handling barrel 3 and a handling chamber 13 for internally mounting the handling barrel 3. The handling chamber 13 is constituted by a lower receiving net 14 and an upper cover 15, and the handling chamber Thresher with the receiving net 14 is transferred from the supply port 16 side opened on the front side to the discharge port 17 side opened on the rear side, while cutting culms all of which are put into the room are transferred in the axial direction of the handling cylinder. Is configured as follows.

The sorting device 18 is provided with an oscillating sorting device 21 in a sorting air passage 20 through which the sorting air from the compressed air Karamoto 19 passes, and is mainly used in the handling chamber 13
The grain that has leaked from the receiving net 14 is received, and is sieving and sorting while swinging and transferring to the rear.

Further, the discharge port 17 of the handling chamber is configured to open at a position rearward of the end of the swing selecting device 21.

Reference numeral 22 is a fried grain spiral, and is configured so that the grain leaked from the leakage net 11 can be fried and conveyed to the sorting device 11.

In the figure, 23 is the first gutter and 24 is the second gutter.
