DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. First, as shown in FIG. 1, the threshing machine 6 has a handling room 2 in which a handling cylinder 1 is internally mounted on an upper side, and a swing sorting shelf 7 which is swingably installed below the handling room 2. Further, a sorting chamber 11 is provided below the sorting chamber 11 in which a pressurized air tray 8, a first transfer spiral 9, and a second transfer spiral 10 are arranged in order from the upper side in the sorting direction. Then, as shown in FIG. 3, the feed chain 12 is provided along the handle of the handling chamber 2, and the spike portion is inserted into the handling chamber 2 through the handling mouth while holding the stem of the grain culm. It is configured to thresh while transporting.

As shown in FIGS. 1 to 3, the threshing machine 6 is provided with a threshing chamber 3 along the back of the handling chamber 2 and a dust-extraction processing extending further rearward from the end of the handling chamber 2. A room 5 is provided. And the threshing chamber 3 is, as shown in FIG.
A threshing cylinder 4 provided with processing teeth 13 on its outer periphery is provided on a shaft so as to treat threshing dust supplied by leaking through a sorting net 14 of a juxtaposed handling room 2. In the case of the embodiment shown in FIG. 2, the sorting net 14 is composed of an upper sorting net 14a (a part leaking and supplying to the threshing chamber 3) and a lower sorting net 14b (sorting) along the axial direction of the handling drum 1. (The part that leaks into the chamber 11), the selection of the upper sorting net 14a is made larger than the selection of the lower sorting net 14b. Therefore, the upper sorting net 14a is apt to leak threshing dust such as spike sticking particles and the like in the handling room 2, and can be quickly supplied to the threshing process chamber 3.

As shown in FIG. 1, the second graining device 15 has a start end connected to the end of the second transfer spiral 10, and an end opened to the start end of the upper threshing chamber 3. Then, the collected second product is fried and supplied. Next, as shown in FIGS. 1 and 3, the dust treatment chamber 5 has a configuration in which a start end is connected to a rear part of the threshing chamber 3 to receive residual dust from the threshing chamber 3, and A transfer port 16 opened to the terminal end of the chamber 2 is formed so as to communicate therewith.
As shown in FIGS. 1 and 3, the dust processing chamber 5 has a dust processing cylinder 17 integrally formed with the threshing processing cylinder 4 and has an interior shaft mounted thereon. Leak frame 1
8 is provided so as to be stretched, and the dust discharge port 19 at the terminal end is opened to the sorting chamber 11. Therefore, the dust processing chamber 5 is
The residual dust in the threshing chamber 3 and the untreated material that was carried around while being threshed in the handling room 2 and reached the terminal portion and did not fall from the dust outlet of the handling chamber 2 to the sorting chamber 11 below. It is configured to take over the dust and re-discharge it again.

Next, as shown in FIG. 1, the swing sorting shelf 7 is arranged in the order of a transfer shelf 20, a chaff sheave 21, and a straw rack 22 from the upper side in the sorting direction to form an integral frame. , Swingably supported, and provided with a sorting chamber 11 by a synergistic action with the sorting wind generated by the pressurized wind 8.
It is configured to perform the sorting operation of the sorting object that has leaked to the container.

Reference numeral 23 denotes a suction / discharge device, and reference numeral 24 denotes a straw chain. Although not shown, the threshing machine 6 configured as described above is mounted on a traveling vehicle body equipped with a mowing pre-processing device at a front portion to form a combine. Next, the operation will be described.

First, the combine starts the engine, engages and operates the threshing clutch, prepares the work while driving the rotating parts of the machine body, moves the traveling vehicle forward, and starts the mowing and threshing work. Then, with the advance of the combine, the grain culm in the field is cut by the cutting pre-processing device at the front, conveyed upward, inherited by the feed chain 12, and supplied to the threshing machine 6. In this way, the culm is fed to the handling chamber 2 from the handle while the stock is clamped and fed by the feed chain 12, and is subjected to threshing by the rotating handling cylinder 1.

The processed material immediately after threshing leaks out of the room through a sorting net 14 extending around the room while being carried around the room by the rotating handling drum 1, and at this time, the upper sorting net Because the selection of 14a is large,
Threshing dust, such as spikesticks, is leaked and supplied to the threshing chamber 3. On the other hand, the degranulated grains leak from the lower sorting net 14b together with dust such as extremely short straw wastes, reach the swing sorting shelf 7 of the sorting chamber 11, and are subjected to swing sorting action.

The threshing dust that has reached the threshing chamber 3 is carried around while being processed by the processing teeth 13 of the rotating threshing cylinder 4, and is subjected to processing and threshing. The waste waste falls into the sorting room 11 below. In this manner, the sorted material that has reached the sorting chamber 11 is transferred on the transfer shelf 20 in the direction of the shelf and reaches the chaff sheave 21, where the grains leak and are separated and separated from the long straw and the like. It is subject to the wind selection action by the sorting wind. The exhausted dust is separated into a dust reaching the suction dusting device 23 and a dust reaching the shelf top rack 22 of the swing sorting shelf 7, and is discharged outside the machine.

Most of the threshing dust that is processed while being carried around by the threshing cylinder 4 in the threshing chamber 3 leaks to the lower sorting chamber 11 and is sorted, but remains and ends. The dust that has reached the section is passed on to the dust processing chamber 5 and processed again. And the unprocessed material in the handling room 2
Sorting room 11 while being carried around by rotating handling drum 1
The dust is sent from the terminal end of the handling chamber 2 to the transfer port 16 side as dust and is supplied to the dust sorting chamber 5 except for those that have leaked.
As described above, the dust is processed by the merge of the dust transferred from the handling cylinder 2 and the threshing chamber 3.

The dust discharged into the dust processing chamber 5 is subjected to the processing action of the dust processing cylinder 17 and the leakage frame 1
From 8, it sequentially leaks into the sorting chamber 11, and when it reaches the final exhaust port 19, all of the dust is discharged into the sorting chamber 11 and undergoes the sorting action. As described above, the objects to be sorted are placed in the sorting room 11.
It is sorted while receiving the synergistic action of the rocking sorting action and the wind sorting action by the sorting wind, and is sorted and separated into the first thing (fine granules), the second thing, and the dust. The second product is dropped and collected by the transfer spiral 9 and harvested outside the machine. The second product is fried from the second transfer spiral 10 by the second grain raising device 15 and returned to the threshing processing chamber 3 to perform the second processing operation. As a result, the dust is exhausted by the suction exhaust device 23, and the straw waste that has reached the storage rack 22 is exhausted from the shelf to the outside.

During such a series of threshing and dusting operations, the handling chamber 2 moves the threshing dust immediately after threshing to the threshing chamber 3 and processes it. Reduced, high-efficiency shedding can be performed with a margin. In addition, the dust processing action is sufficiently performed by a long processing step from the threshing chamber 3 to the dust outlet 19 at the end of the dust processing chamber 5.

Therefore, the threshing machine 6 according to the present invention can reduce the load on the handling cylinder and improve the threshing processing capacity, and can be mounted on a high-efficiency combine for multi-row cutting. . Moreover, the threshing machine 6 has a feature that the dust removal loss can be reduced because the dust removal process is lengthened, the processing accuracy is enhanced, and the sorting is improved.
