Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a normal combine No. 2 reducing device.

[0002]

2. Description of the Related Art Since a normal combine harvester feeds cut culms to both the culm and the handling room for threshing, the amount of dust, such as broken culm, increases, and therefore the second reduction amount is self-destructing. Increase compared to the ones. And this large amount of 2
Since the food is returned to the starting end of the handling room and is processed together with the cut culm newly supplied to the handling room, not only a large amount of power is required but also the processing efficiency is lowered.

[0003]

As described above, in the conventional ordinary combine harvester, a large amount of No. 2 object is returned to the handling room and reprocessed. Therefore, a large amount of power is required and the processing capacity is lowered. Therefore, the present invention divides this large amount of No. 2 product into those that require threshing treatment and those that do not require threshing treatment. In addition to eliminating the disadvantages of the prior art, it is also possible to reduce the efficiency of the treatment by reducing it to the proper place such as on the rocking sorter, and reducing it to the handling room while treating the one that requires threshing treatment. The present invention was invented for the purpose of providing a device which is good and does not cause damage particles such as depowder particles.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a processing cylinder chamber horizontally above the starting end of the chamber so that the processing cylinder is orthogonal to the processing cylinder. The starting end of the processing barrel and the second material collecting gutter are communicated with each other through a grain elevator, and the starting end of the processing barrel is passed through the receiving net onto the rocking sorting body and the trailing end is moved into the handling chamber. It is characterized in that they are connected to each other.

[0005]

With this structure, the second product collected in the second product collecting trough is thrown into the starting end portion of the processing cylinder chamber by the grain lifting machine, and the starting end is determined by the rotation of the processing cylinder. It is processed while being sent to the crocodile. At that time, the grains in the No. 2 product put in the starting end and the grains whose starting end is processed by the processing action in the wa After passing through the receiving net, it is returned to the rocking sorting body and is re-sorted.For those that do not pass through the receiving net, the terminal end reaches the end while falling into the handling room while receiving the processing action in the processing chamber. It will be reprocessed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. (9) is a traveling device for supporting a machine base (10),
On the left side of the machine stand (10), there is a handling room (1) in which a screw-type handling barrel (3) is installed in a front-back direction, and a handling room (1) is provided below the handling room (1). ) Is equipped with a threshing sorting device (B) consisting of an oscillating sorting body (8) for sorting threshing from (3) and a sorting section (12) which constitutes a sorting air passage (11), and a steering unit is provided on the right side thereof. Part (13) and grain tank (14)
To the front and back of the threshing selection device (B).
A mowing device (A) is provided in series through a dummy house (15), and a grain culm mowed by the mowing device (A) is fed by a feeder.
The inside of the house (15) is sent up and supplied to the handling room (1).

The cutting device (A) is provided with a grass body (16), a cutting blade (17) and a scraping auger (18) side by side.
A scraping reel (19) is provided above the front side of 7),
Feeder house (1) connected to the threshing selection device (B)
5) It is configured to be vertically adjustable about the rear end of the shaft.

Further, the swing selecting body (8) has a feed pan (20), a first chaff sheave (21), a spoke body (22) and a second chaff sheave from the beginning to the end. (23) are provided in sequence, and a Glen sieve (24) is arranged below the first chaff sheave (21) so that these can swing back and forth as a unit. .

In the sorting air passage (11) blown up from the lower side of the rocking sorting body (8), the sorting air blown by the pressure fan (26) provided below the feed pan (20) blows. As a result, the number 1 gutter (27) and the number 2 recovery gutter (5) are provided at the bottom of the sorting air passage (11).
The first product collected in the product gutter (27) is stored in the grain tank (14).

Reference numeral (28) is a rotating scraping blade, (29) is a dust outlet, and (30) is a grain tank (14).
It is a discharge ogre that takes out the grains stored inside.

Next, (2) is a processing barrel chamber in which the starting end of the handling chamber (1) is laterally provided above the processing barrel (2), and the processing barrel chamber (2) is handled by a processing barrel (4) installed therein. The processing cylinder chamber (2) is provided in a state orthogonal to the handling cylinder (3) in the chamber (1). One side of the processing cylinder chamber (2) has an inlet port (31) at the starting end and the other side of the processing cylinder chamber (2) at the terminal end of the process. Each has a drop opening (32) opened, and a receiving net (7) is stretched around the lower side of the starting end.

Then, the input port (31) opening at the starting end of the processing chamber (2) and the second material collecting gutter (5) are communicated with each other by a grain elevator (6), and the chamber (2) is closed. The starting end of the rocking sorting body (8) communicates with the saw through the receiving net (7) and the flow path (33), and the falling end (32) of the ending end of the swinging sorting body (8) communicates with the handling chamber (1). The starting point of is open to alligators.

Therefore, the second product collected in the second product recovery gutter (5) is lifted by the grain elevator (6) and is fed from the input port (31) to the starting end of the processing chamber (2). Then, the processing cylinder (4) is rotated and the end of the processing cylinder is sent to the crocodile and is subjected to the processing action. At that time, the grains in the second product thrown into the starting end portion pass through the receiving net (7) and fall down the flow-down path (33) as shown by the arrow (a), so that the rocking sorting body (8) is discharged. Those that are returned to the upper end and re-sorted and do not pass through the receiving net (7) receive the processing action of the processing cylinder (4) and reach the end and reach from the drop opening (32) as shown by the arrow (b). The starting end of the handling room (1) falls into the crocodile and is reprocessed.

Industrial Applicability As described above, the present invention is a normal combine for supplying threshing culms to the handling room (1) and threshing treatment, and the starting end of the handling room (1) is The processing cylinder chamber (2) is horizontally installed on the upper part of the chamber so that the processing cylinder (4) is orthogonal to the handling cylinder (3), and the starting end portion of the processing cylinder chamber (2) and the second object recovery gutter (5). ) Through the grain elevator (6), and the starting end of the processing chamber (2) is passed through the receiving net (7) to the rocking sorting body (8) and the end end is treated in the chamber ( Since it is characterized in that they are connected to 1) respectively, a threshing process is required to reduce a large amount of the 2nd product collected and collected in the 2nd product collection gutter (5). Separated into unnecessary and unnecessary ones, only those requiring threshing treatment are returned to the handling room (1) for reprocessing, and those not requiring treatment are returned to the rocking sorter (8). In this way, it is possible to reduce the threshing treatment efficiency while reducing the required power while reducing the required power while providing a treatment function to the threshing treatment and reducing it to the handling room (1). In addition, since only the second product requiring threshing treatment is returned to the handling chamber (1), it is possible to reduce the generation of damaged grains such as shedding grains.
