In the figure, reference numeral 1 denotes a threshing machine with a processing cylinder according to the present invention, wherein the threshing machine 1 is provided with a sorting chamber 2 at a lower portion, and a handling chamber 4 having a handling cylinder 3 mounted above the sorting chamber 2; And a processing drum chamber 6 having a processing drum 5 of a length extending from the front of the processing chamber 4 to the rear thereof, and communicating with each other via a dust outlet 7 at the rear of the processing chamber 4. On one side of the handling room 4, a grain stalk feeding device 8 for supplying grain stalks to the handling room 4 is provided along the handling port.

[0007] The processing cylinder 5 has a front processing cylinder 5 ₁ ahead Okuchiriguchi 7, a central processing cylinder 5 ₂ facing the Okuchiriguchi 7, the rear processing torso behind the Okuchiriguchi 7 5 ₃ of a dividable structure in the three-part, as shown in FIG. 3, the front processing cylinder 5 linear processing teeth 5a suitable for threshing twigs infarction in _1, helix 5b suitable for transfer to the central processing cylinder 5 _2, the rear processing cylinder 5 ₃ plate treated tooth 5c suitable for transfer and processing of Kuzumono is provided. The processing cylinder chamber 6 has a second reduction port 6a opened on the upper surface of the starting end,
A discharge port 10 is provided at the rear of the processing cylinder chamber 6 and opens to a dust chamber 9 behind the handling chamber 4. A dust suction fan 11 is provided at a front surface of the discharge port 10 with a slight space between the processing cylinder 5 and the shaft. The directions are arranged orthogonally. Reference numeral 12 denotes a leaking body of the handling room 4 stretched substantially along the lower half circumference of the handling cylinder 3, and reference numerals 13 ₁ and 13 ₃ substantially along a half circumference of the front and rear processing barrels 5 ₁ and 5 _{3 on} the handling chamber 4 side. Moshita of the processing cylinder chamber 6 is stretched Te, 13 ₂ Moshita of the processing cylinder chamber 6, which is stretched along move out the Okuchiri port 7 substantially lower portion of the central processing cylinder 5 ₂ half, 15 Sorting room 2 under the fuselage
A second forward spiral in which the rear end is connected to the end of the second transverse spiral 14, and a second reduction spiral 16 in which the lower end is connected to the front end of the second forward spiral 15. The portion is connected via a conduit 17 to the second product reduction port 6a on the upper surface of the starting end of the processing cylinder chamber 6.

In the above configuration, when the cereals are supplied to the handling room 4 by the cereals feeding device 8, the cereals are threshed by the linear teeth 3a of the rotating rotating drum 3 while being transported backward along the opening. The threshed grains leak down the leaking body 12 in the handling room 4 and fall on the swinging sorting body 18 in the sorting room 2 below, and the unleaked material is processed through the dust outlet 7 at the rear of the handling room 4. It is sent out to the trunk room 6. The grains mixed with the contaminants dropped onto the oscillating sorter 18 are sequentially transferred rearward while being sorted by specific gravity by the oscillating motion of the oscillating sorter 18, and the fine particles leaked from the oscillating sorter 18 Are collected in the hopper by the first horizontal feed spiral 19 and the first deepest spiral 20, and the foreign substances which do not leak the rocking sorter 18 are selected by the wind of Karamin 21 and the second one is The second horizontal feed spiral 14, the second forward spiral 15, and the second reduction spiral 16 reduce the waste from the second product return port 6a to the start end of the processing cylinder chamber 6, and the swinging motion of the swing sorting body 18 and The contaminants separated by the compressed air are sent to the dust chamber 9 at the rear of the sorting chamber 2 and are discharged from the dust outlet 22 to the outside by the dust suction fan 11.

On the other hand, the double-dip product which is reduced to the starting end of the processing cylinder chamber 6 by a double-dip reduction helix 16, the front processing cylinder 5 ₁
Threshing reprocessing twigs rachis of double-dip reduced product in the linear processing teeth 5a is transferred to the central processing cylinder 5 ₂ while made of, and wherein the untreated product delivered from threshing chamber 4 the rear of Okuchiri port 7 are merged, deported to the rear processing cylinder 5 ₃ by central processing cylinder 5 _second spiral 5b, untreated product has been transferred to the rear processing cylinder 5 _3, the plate-like treated tooth 5c of the rear processing cylinder 5 ₃ Kuzumono The remaining particles are transferred to the rear while the remaining particle processing is performed, and the remaining waste is discharged from the discharge port 10 at the rear of the processing drum 5 to the dust chamber 9 by the dust suction fan 11, and discharged to the outside from the dust port 22. You.

In the above process, it is treated at the front processing cylinder 5 ₁ and a rear processing cylinder _3, Moshitatai 13 _1, 13 _2, 1
3 ₃ and a leakage of beat, Moshita product that has fallen to the swinging sorting member 18 of the sorting chamber 2, as well as the leakage bottom product from the threshing chamber 4, the swing sorting member 1
8 and the pressure wind of Karamin 21. Fine particles are collected in the hopper by the first horizontal spiral 19 and the first deepest spiral 20. The second product is the second horizontal spiral 14, the second. Forward spiral 1
5, reduced to the processing chamber 6 by the second reduction spiral 16,
Impurities separated by the oscillating motion of the oscillating sorter 18 and the compressed air of the Karamin 21 are discharged out of the machine through the exhaust port 22 of the exhaust chamber 9.

The front, middle and rear processing cylinders 5 ₁ ,
5 _2, 5 ₃ processing teeth, linear processing teeth 5a, helix 5b,
Not only the plate-shaped processing teeth 5c but also other types may be used according to the type of crop, threshing conditions, and the like. In this case, for example, the driving shaft of the processing cylinder is set to a hexagonal axis for rotation prevention, and different processing is performed. Hexagon holes are used as the shaft holes of the multiple types of divided processing cylinders provided with teeth, and the processing cylinder provided with the necessary processing teeth is appropriately replaced with a hexagonal drive shaft. Thus, it is possible to perform highly accurate processing.

[0012] Figure 4 is a front, middle, processing cylinder 5 ₁ divided to the rear, the 5 _2, 5 ₃ of the drive shaft and two concentric shafts 23 and 24, rotation of the inner and outer drive shafts 23 and 24 different In this example, the peripheral speeds of the divided processing cylinders 5 ₁ , 5 ₂ , and 5 ₃ were changed by driving with a number, so that accurate and accurate processing was performed on a wide range of materials similarly to the processing cylinders. is there. A processing cylinder 5 in the illustrated example, at the front processing cylinder 5 ₁ inner shaft 23, central processing cylinder 5 ₂
And drives the rear processing cylinder ₃ with a common outer shaft 24, the front processing cylinder 5 ₁ and central, is obtained by changing the rear processing cylinder 5 _2, 5 ₃ and the peripheral speed.

Further, the leaking bodies 13 ₁ , 1 of the processing cylinder are provided.
3 _2, 13 ₃ as well, the split portions 5 ₁ of the processing cylinder 5, 5 _2, 5 ₃
By selecting and using the most suitable material and mesh for each case, it is possible to perform accurate and accurate processing, as in the case where the processing teeth are changed. For example, the processing Moshita 13 ₁ 9-10 milli second crimp network torso, or the use of punching network 12 millimeter φ holes, the residence time of the relatively eye fit is limited under leakage because of their small treated , And the treatment is performed favorably. Moreover, the use of punching network Moshita 13 ₂ to 15 millimeters φ hole in the central processing drum, clogged by catching the likely long culm occur crimp network is reduced. Further, the rear processing cylinder With punching network Moshita 13 ₃ to 18mm hole, taking out of the grain from the processing cylinder chamber 6 a rear portion of the outlet 10 is reduced, such as to improve the recovery yield of grain The effect is obtained.
