Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a combine No. 2 reduction processing apparatus capable of reducing No. 2 by a thrower above the front end side of an axial flow type handling cylinder in a threshing section. .

[Conventional technology]

Conventionally, the tip of the jumping cylinder of the No. 2 reduction thrower is attached to the reducing port that is opened above the front of the threshing unit and above the front end of the axial flow type handling cylinder in parallel with the axial direction of the handling cylinder. In a combine constructed by connecting in series, the applicant has already applied for
As can be seen from No. 61-154082, the jumping cylinder had a structure in which the tip of the jumping cylinder communicates with the reducing port as it is without being expanded while being straightly extended obliquely upward.

[Problems to be solved by the invention]

Due to such a structure, when a non-mass substance such as straw scraps becomes a wet material and is bounced up by the thrower, the flight force decreases and it stalls on the way and falls and adheres to the belly surface of the hoisting cylinder. Or the backflow may occur and the inside of the hoisting cylinder may be blocked, and the rotation direction of the handling cylinder is orthogonal to the throwing-in direction of the hoisting cylinder. There was a problem in that the wind pressure would make it easier to close the return port while passing just before the return port, and the throwing force from the jumping cylinder would be lost and clogged.

[Means for solving problems]

The present invention solves the problem and makes it possible to reliably return the second item by the thrower. Therefore, the lower end edge of the return port is lowered until it approaches above the front end of the handling cylinder. The upper portion of the thrower cylinder is formed obliquely upward and extends downwardly from the midway of the belly surface of the jumping cylinder to the lower edge of the return port.

[Action]

Therefore, it is possible to reduce the length of the belly surface of the hoisting cylinder and make the rising angle of the hoisting cylinder steep, so that the wet material that stalls and falls during the hoisting can be handled from the inclined surface. It will be possible to smoothly return to the side of the handling cylinder, and it is also difficult for the processing object on the handling cylinder side to enter the jumping cylinder side from the return port, and the second object can be smoothly transferred to the handling cylinder side from the inclined surface. It will be possible to drain it.

〔Example〕

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

Fig. 2 shows a side view of the combine, in which a paddy tank (7) is connected to the side of the threshing section (A) mounted on the machine supported by both crawlers (6). ) Is equipped with a boarding operation section (C), and a feeder (11) is provided behind the cutting section (D) having a take-up reel (8), a cutting blade (9), a take-up auger (10), etc.
A feeder chamber (E) in which the above is installed is integrally connected, and a rear portion of the feeder chamber (E) is connected and communicated with a front portion of the threshing unit (A) to have the same structure as the conventional structure.

Further, the threshing portion (A), the front end portion (1a) side has a frustoconical shape and the screw (1b) is attached to the outer periphery of the axial flow type handling cylinder (1).
Is mounted on the upper part in the machine front-rear direction, and installed so that the rear end of the feeder chamber (E) communicates with the lower side of the front end (1a) of the handling cylinder (1). The dust outlet (12) is located below the end of 1).
And a swinging sorting body (14) is installed under the sorting net (13) stretched below the handling cylinder (1), and a compressed air fan is installed below it.
(15) No. 1 spiral conveyor (16) and No. 2 spiral conveyor (17) are arranged respectively, and from the end side of No. 2 spiral conveyor (17), it is diagonally upward along the outer side of the machine. The return conveyor cylinder (18) is extended to have the same structure as the conventional structure.

A front wall (19) facing the front of the front end (1a) of the handling cylinder (1)
The No. 2 treatment case (20) is connected to the upper part of the front side of the threshing part (A) which is outside of the, and the front end part (1a) of the handling cylinder (1) is installed at the upper part of the front wall (19). The return port (2) with the lower end edge (2a) lowered so as to approach upward is formed in a large size by making it slightly longer in the vertical direction than the conventional type, and at the inner lower part of the No. 2 processing case (20), Conveyor gutter with an inlet (21) above and a spiral conveyor (22) inside
(23) is installed horizontally, and the upper part of the No. 2 reduction conveyor cylinder (18) is connected to the outer end of one side of the transfer gutter (23) so that the lower cylinder
One end side of the spiral conveyor (22) is extended into the thrower barrel (4) of the second object reducing thrower (B) configured by extending the jumping cylinder (3) obliquely upward from the upper part of (4). A jumping cylinder that extends upwards and has a jumping blade (24) installed on its axis and extends obliquely upward.
The upper end of (3) communicates with the return port (2), but
The lower inclined surface (5) extends from the middle of the belly surface (3a) on the lower side of (3) to the lower end edge (2a) of the return port (2).

Therefore, since the inclined surface (5) was extended from the middle,
The extension length of (3a) is shorter than the conventional type, and
The rising angle of the jumping cylinder (3) can be suddenly taken,
Jumped up from the lower body (4) as shown by the arrow (2) 2
Even if the wet material in the reduced product stalls and falls, it becomes difficult for the wet material to be deposited on the abdominal surface (3a), and the wet material falls on the inclined surface (5) and is thrown onto the handling cylinder (1).

Further, since the slanted surface (5) is located outside the reduction port (2), the slanted surface (5) It is difficult to move to the () side and the return port (2) side is prevented from being blocked.

In this way, the second product returned from the lower part of the threshing part (A) will not be clogged by the lower (B) and will be handled smoothly.
It will be reduced to the (1) side and processed.

[Effect of device]

As described above, according to the present invention, since the inclined surface (5) is obliquely set low from the middle of the belly surface (3a) to the lower end edge (2a), the extension direction length of the belly surface (3a) of the jumping cylinder (3) is set. It is short, and the rising angle of the jumping cylinder (3) can be configured to be steep,
Wetting material that stalls and falls from the second object that is jumped up can be smoothly discharged from the inclined surface (5) without accumulating on the abdominal surface (3a).
The processed material on the (1) side does not enter the sloped surface (5) side, and it does not get stuck in the thrower, and it is good and smooth. 2
Since it can be reduced, it has a feature that it can be suitably implemented with a simple structure.
