Description

[Detailed description of the invention] The present invention is a cone-type rotary sorting mechanism configured to supply a workpiece to the small-diameter end side of a rotary sorting mechanism that has a conical rotary processing cylinder housed inside a conical rotary cone cape. The present invention relates to a threshing sorting device, and is intended to be able to carry out sorted grains with a simple structure by effectively utilizing the structure of a rotating sorting mechanism.

Embodiments of the present invention will be described below based on illustrative drawings.

FIG. 1 shows the overall side surface of the combine harvester, and FIG. 2 shows the overall plan view. A reaping pre-processing section 4 is installed in the front part of a chassis 3 equipped with crawlers 1, 1 and a threshing device 2, which can be raised and lowered.
In addition, a cockpit 5 and a grain collection dock 6 are provided on the side of the aircraft.

The reaping pre-processing section 4 includes a pulling device 7, a clipper-type reaping device 8, a horizontal conveying device 9 for horizontally conveying and merging a plurality of cut culms, and a lateral conveying device 9 for conveying the merging culms rearward and upward. Consisting of a rear conveyance device 10 etc. that gradually changes to a sideways posture,
In addition, the rear conveyance device 10 is also configured to adjust the handling depth by changing its posture.

The threshing device 2 has the rear conveyance device 10 on its side.
In addition to being equipped with a feed chain 11 that inherits the reaped husk in a sideways posture and conveys it rearward, there is also a straw cutter 12 at the rear that shreds the threshed waste straw, and a waste straw that conveys the waste straw in an inclined rear direction. Equipped with straw chain 13.

In the present invention, the threshing device 2 is constructed as follows, and the details thereof are shown in FIG. 3.

At the front of the threshing device 2, there is a well-known handling cylinder 14 that acts on the grain-bearing part of the culm that is pinched and conveyed by the feed chain 11.
A handling chamber 16 is provided, in which a crimp net 15 is stretched over the lower part of the handling chamber 16, and a rotary sorting mechanism 17 is provided at the rear lower part of the handling chamber 16.

The rotary sorting mechanism 17 includes a conical cone cape 18 that is rotated for one drive around an axis P2 parallel to the handling cylinder axis P1, and a conical processing cylinder 19 that is concentrically housed inside the cone cape 18. The small diameter end portions thereof are arranged so as to face the lower rear end of the handling chamber 16.

Both 1B and 19 are each transmitted by a belt to an extended portion of the processing cylinder shaft 20, and the processing cylinder 19 is driven to rotate in the same direction at a sufficiently high speed than the cone cape 18.

(For example, cone cape = 25 Orpm, processing cylinder: 150
0 rpm) The cone cape 18 is connected to the large diameter ring member 1
8a and the small diameter ring member 18b are connected to the vibe stay 18c...
- A mesh net 18d through which grains can pass is stretched over a conical frame connected with A conical collection case 21 is provided.

Further, the large diameter ring 18a is provided with a thrower blade 22 for sending out the grains collected in the large diameter part of the collection case 21 to the tank 6.
... and a dust exhaust fan 23 is installed to discharge the filtration residue inside the cape to the outside of the device.

The processing barrel 19 is made of sheet metal, and its small-diameter front end portion is configured as a steeply inclined conical portion, and several protrusions 24 along the conical generatrix are provided on the outer circumferential surface of the rear portion thereof. There is.

Further, at the front end of this processing cylinder 19, there is a terminal opening 25 of the threshing and handling chamber 16 where the crimp net 15 of the handling chamber 16 has been filtered.
Auger 2 that sends the unfiltered material from the filter to the sorting mechanism 17
6 are arranged concentrically.

The threshing sorting device of the present invention is constructed as described above, and the grains and fine straw waste of the processed material separated from the conveyed husk by the handling process in the handling room 16 are passed through the Klins net 15. The twig stalks and relatively large straw debris that have passed or have not passed fall from the opening 25, and are sent to the auger 26, respectively.
and is forcibly conveyed to the small-diameter entrance of the rotary sorting mechanism 17.

The processed material that has entered the mechanism 17 is sent backward as the cone cape 18 rotates at a low speed, and is agitated and rotated by the processing cylinder 19, which rotates at high speed in the same direction, and moves in a spiral shape. The grains pass through the net 18d of the cone cape 18 by centrifugal force and are collected in the case 21.

Further, the twig stalks are subjected to a single grain treatment by stirring between the processing barrel 19 and the cone cape 18, and the single grains are similarly collected in the case 21.

Then, the fine grains collected in the case 21 flow down to the rear end side of the large diameter, are flipped up by the thrower blades 22, and are transported to the tank 6 via the thrower tube 27 connected from the case 21. .

Further, fine dust, straw waste, etc. inside the cone cape 18 are forcibly sucked by an exhaust shaft fan 23 at the rear end of the cape and discharged from the lower part of the cutter 12 to the outside of the machine.

FIG. 5 shows another embodiment of the present invention, in which the collection case 21 is connected to the corn cape 18 and configured to be driven and rotated, so that the collected grains can be smoothly transferred to the thrower blade 22 side. It will be held in

Further, in this case, if a spiral protrusion or the like is attached to the inner surface of the collection case 21, more reliable transportation becomes possible.

In the embodiment, the thrower blade 22 is provided at the large diameter end of the cone cape 18, but it may be provided at the small diameter end or in the middle depending on the case.

As explained above in the embodiments, the cone-type threshing sorting device of the present invention has a thrower blade on the rotating yaw/cape itself, so the structure is simpler and can be implemented at a lower cost than when a dedicated carrying-out mechanism is provided. It is.
