Description

[Detailed explanation of the idea] The present invention relates to a waste culm processing device.

In recent years, with the downsizing of combine harvesters, it is necessary to rationally incorporate the desk-type cutter into the combine main body, making it necessary to utilize the clipping capacity of the combine. For this reason, the fulcrum of the rotation axis of the passage switching body of the culm has to be installed relatively behind the cutter cover, that is, at a position behind the cutter mechanism. It may get caught in the acute-angled gap formed by the upper side of the cutter case and the shaft support of the switching body, causing cutting problems, and the smooth supply of the culm to the cutter mechanism becomes impossible. Significant drawbacks were observed, such as reduced efficiency in shredding the culms.

The present invention was developed in view of the above circumstances, and aims to eliminate the drawbacks of the conventional technology with a simple configuration, and to improve the processing efficiency of the waste culm by smoothly supplying the waste culm to the cutter mechanism. That is.

To explain the details of the embodiment with reference to the drawings, A is a combine main body, B is an automatic threshing device, C is a desk type cutter, and D is a running body.

In the figure, 1 is a conveyor for the discharged culm, 2 is a conveyor for conveying the discharged culm diagonally toward the tip side, and the above-mentioned desk-type cutter C has a high-speed rotary blade 4 mounted on the cutter case 3, The upper part of the cutter mechanism is composed of a low-speed rotary blade 5, a feeding screw conveyor 6, a discharge port 7, etc., and is also constituted by the high-speed and low-speed rotary blades 4 and 5. The supported culm passage switching body 8 is provided so as to be openable and closable.

Reference numeral 9 denotes an upper cover, and a cutout window 10 is formed on the side surface of the upper cover 9, that is, on the side wall on the root side of the culm, and is parallel to the conveyor of the culm and has a large opening. The lower edge is cutter case 3 above.
The position is approximately the same as the upper edge of the switching body 8.
The pivot point is located rearward of the cutter mechanism constituted by the rotary blades 4 and 5, that is, near the intersection of the lower edge of the cutout window 10 and the rear end upright edge.

A notch 11 is provided at the end of the switching body 8 on the side of the culm root. As is clear from FIG. 2, this notch 11 is formed to include the high and low speed rotary blades 4 and 5 at the extreme end to ensure reliable cutting of the intervening culm root. .

In the figure, 12 is a switching handle of the switching body 8, 13 is a notch provided in the switching body 8 corresponding to the culm transporting body 2, and 14 is an exhaust pipe with an edge facing the notch 13 of the switching body 8 formed in an upright manner. It is a culm guide rail.

In the device configured in this way, the switching body 8 has a double structure with the lower side bulging from the front to the rear, and therefore downward, as shown in Figures 1 and 3. The switching body 8 is supported by a frame 15 provided on its shaft.

Then, the end of the horizontal rod portion of a rectangular-shaped regulating member 16 is attached perpendicularly to one side edge of this frame 15, that is, the substantially central portion of the frame side facing the notch 11, and furthermore, the regulating member 16 is vertically The rod portion 16' is inserted into a notch 17 provided at the upper edge of the cutter case 3.

The vertical rod portion 16' of this regulating member 16 is in the first position when the switching body 8 is rotated upward in the state shown in FIGS.
As shown in the figure, the base of the culm is forcibly fed to the cutter acting part between the rotary blades 4 and 5, and the base of the culm is guided and clamped to the shaft support of the switching body and the cutter case. This is to prevent the trouble of not being cut, and the reason why the vertical rod part 16' of the regulating member 16 is inserted into the upper edge notch part 17 of the cutter case as shown in FIG. This is to prevent the root portion of the culm from being caught between the outer surface of the vertical rod portion 16' and the inner surface of the upper edge of the cutter case.

Since the present invention is configured as described above, the following effects can be obtained.

(a) Grain culm is forcibly conveyed by a conveyor while being threshed by an automatic threshing machine, and the waste culm is conveyed obliquely by the conveyor from the automatic threshing machine outlet, and then the grain culm is forcibly conveyed by a conveyor and adjusted by the automatic threshing machine. Therefore, it goes without saying that the culm is shredded or collected into culms using a desk-type cutter. Therefore, when the culm is a long culm, the root part of the culm resting on the upper edge of the cutter case 3 stands up as the other culm parts are pressed downward by the action of the switching body. The notch part 11 helps the user to change the posture, and the root part of the culm can smoothly pass between the blades of the desk type cutter.

(c) The root of the culm whose posture has changed to the upright state at the notch 11 is prevented from being conveyed backward by the horizontal rod of the regulating member 16, and the root of the culm is continuously transferred and supplied. is not guided by the cutter mechanism and is caught in the acute-angled gap formed between the vicinity of the shaft support of the switching body and the upper edge of the cutter case,
This structure can rationally prevent troubles such as the accumulation of these phenomena and the inability to perform shredding, and allows smooth supply of waste culm to the cutter mechanism, thereby improving waste culm processing efficiency. It can be measured by
