Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a processing device for crops discharged from a combine harvester, which is equipped with a handling barrel that threshes crops while conveying them rearward.

[Prior art and its problems] Conventionally, the above type of combine harvester is known as Utility Model Application No. 60-41139. However, this system discharges the crops from the threshing section and the sorting section, and if a crop processing device were installed, the overall length would become longer.

Furthermore, as seen in Japanese Utility Model Application Laid-open No. 60-49739, there is a method in which a sorting device is provided at the rear of the handling cylinder, and a processing device is further provided at the rear thereof. However, in this case, the culm would remain in the sorting room for a long time, and the total length would become extremely long.

[Problems to be Solved by the Invention] The present invention attempts to solve the above-mentioned problems and shorten the overall length while providing a waste crop processing device.

[Means for solving the problem] Therefore, in the present invention, a sorting device is provided below the handling cylinder, and the handling cylinder is extended to the rear from the rear end of the sorting device, so that the sorting device and the handling cylinder can be separated from each other. A discharged crop processing chamber for receiving a discharge device is provided such that its starting end enters below the terminal end of the handling cylinder.

[Operation and Effect] Therefore, the crops discharged from the handling barrel and the crops discharged from the sorting device are processed together in the crop processing room. Since the crop processing room makes use of a portion of the space created by the layout of the handling barrels and sorting equipment, it is possible to receive crops smoothly and to shorten the overall length.

〔Example〕

Next, the embodiment shown in the drawings will be described.

FIG. 2 shows a side view of the combine harvester. In front of the threshing section A mounted on the machine body supported by both crawlers 9, there are a reel 10, cutting blades 11, and a scraping auger 1.
2. A reaping section B consisting of a feeder 13 and the like is arranged in series, and the threshing section A has a screw handling barrel 1 mounted in the upper interior thereof in the longitudinal direction of the machine, which is equipped with a discharge blade 1a on the outer periphery of the terminal end, and the screw A crimp net 14 is stretched below the handling drum 1, and a downwardly directed culm outlet 2 is formed at the bottom of the terminal end.
6, pressure fan 17, No. 1 spiral conveyor 18,
A No. 2 spiral conveyor 19 is provided to constitute a sorting section, and a cross-flow fan-shaped dust exhaust is installed above the rear part of the swing sorting body 15, which is the terminal end of the sorting section, and in front of the lower side of the discharge culm 2. A fan 3 is installed and a dust exhaust port 4 is formed at the lower rear side of the fan 3, so that the structure is similar to the conventional structure.

The exhaust culm port 2 and the dust exhaust port 4 are connected to the front part of a wide dust exhaust cylinder 5 that extends rearward, and the rear end of the dust exhaust cylinder 5 has an opening facing the rear of the machine body. 8, and a large number of blades 6a are arranged on the outer periphery at the upper front part of the dust exhaust cylinder 5, which is directly under the exhaust culm opening 2, and has a length that is approximately the same as the width of the dust exhaust cylinder 5. A beater 6 is rotatably mounted on a shaft, and a large number of blade portions 7 are disposed on the outer periphery of the dust exhaust drum 5, which is a part where the outer sides of the dust exhaust ports 4 meet on the lower side of the beater 6.
A chopper 7 is rotatably mounted on a shaft so that a is laterally overlapped with the blade 6a of the Peter 6,
A large number of receiving blades 20 are fixed to one shaft 21 and installed in parallel on the lower surface of the dust removal cylinder 5 directly below the chopper 7 in a manner that they stand up and approach each blade part 7a of the chopper 7. The shaft 21 is rotated to adjust the inclination of each receiving blade 20.

In addition, one inner side surface 27a of the dust exhaust cylinder 5, which is the inner side of the opening 8, is curved so as to open to the side of the cut side of the machine body, and the inner side of the opening 8 Each guide plate 22 is configured to be curved at intervals in the same manner as the inner surface 22a, respectively, and stands upright from the bottom surface, but each guide plate 22 may also be configured to hang down from the top surface.

Therefore, during work, reaping and threshing are performed in the same manner as before, and the waste culm is discharged from the terminal end of the screw handling barrel 1 by the discharge vane 1a from the waste culm opening 2 as shown by arrow A. At the end of the sorting section, the dust is discharged from the dust exhaust port 4 as shown by the arrow C by the dust exhaust fan 3 that sucks dust as shown by the arrow B, but the dust discharged from the exhaust culm port 2 is The culm is dispersed while being knocked down by the rotating Peter 6 as shown by arrow D, and the culm is combined with the abrasion from the dust exhaust port 4, and the culm is thrown off by the Peter 6 while rotating as shown by Arrow E. The chopper 7, which uses the blade 7a to cut off the culms that are about to get entangled with the culm, scrapes them off and then works with the receiving blade 20 below to cut them into small pieces, so that they are dispersed in the width direction. Then, the dust is vigorously sent out backwards as shown by the arrows, and while being dispersed and guided by each guide plate 22, it is widely dispersed and released from the opening 8 toward the rear of the machine as shown by the arrows. That will happen.

In that case, the curved inner surface 22a or the guide plate 22
As a result, the dust is dispersed closer to the rear of the cut side of the machine body, and it is possible to prevent the dust from getting on the planted grain culms on the uncut side.

Further, by rotating each receiving blade 20 around the shaft 21 to adjust the inclination, it is possible to adjust the cutting state or the backward discharge depending on the amount of dust to be discharged.

In the embodiment, the device for treating discharged crops is provided with the beater 6 and the chopper 7, but either one of them may be used, and in short, any device capable of receiving and treating discharged crops will suffice.
