Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a processing cylinder and a processing cylinder which are arranged side by side in parallel with each other, and a processing chamber in which the processing cylinder is mounted on an inner shaft can be swingably opened and closed outward with respect to the processing chamber. A threshing treatment device for a combine.

[0002]

2. Description of the Related Art Conventionally, in this type of combine threshing processing apparatus, there is known a processing chamber arranged side by side on one side of the processing chamber together with a processing drum so as to be capable of swinging open / close with respect to the processing chamber. .

[0003]

However, the conventional technique has a complicated structure because a supporting device for swinging and opening the processing chamber must be additionally provided. An object of the present invention is to eliminate the above-mentioned problems of the prior art. Therefore, the following technical measures were taken.

[0004]

[Means for Solving the Problems] That is, the technical means according to the present invention is a threshing process with a receiving net, while the handling barrel 6 is internally mounted on an inner shaft and the supplied grain culms are transferred in the axial direction. A processing chamber 11, and a processing chamber 12 provided on one side of the processing chamber, in which a processing cylinder 7 that receives the processed material from the processing chamber and transfers the processed material axially is processed. It is composed of a grain tank 15 mounted on the outside of the processing chamber, and a fried grain discharge pipe 16 erected at the rear of this grain tank. The present invention is characterized in that it is configured so as to be capable of swinging and opening and closing around the grain discharge cylinder 16 as a rotation center.

[0005]

Therefore, according to the present invention, since the processing chamber can be opened and closed by swinging outward with respect to the handling chamber, it is possible to easily maintain the processing chamber as well as the handling chamber. Since the processing chamber is centered around the fried grain discharge cylinder of the Glen tank, it can be implemented inexpensively without requiring a complicated supporting device for the processing chamber. Moreover, since the processing chamber is supported by the fried grain discharge cylinder, the processing chamber becomes strong.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated example, 1 is a running frame, 2 is a running crawler, 3 is a machine stand, 4 is a threshing unit, 5 is a feed chain, 6 is a handling cylinder, 7 is a processing cylinder, and 8 is a processing cylinder. Mowing unit, 9 is a cutter
Such as a working machine, 10 is a waste straw conveying device, 11 is a handling room, 12
Is a processing chamber, 13 is a driver's seat, 14 is a control section, 15 is a gren tank, 16 is a fried grain discharge cylinder, and 17 is a discharge auger.

In the handling chamber 11, a handling barrel 6 which rotates around an axis in the longitudinal direction of the machine is installed, and a receiving net 11a is stretched along at least the lower half of the handling chamber. A feeder chain 5 is stretched on one side of the handling room, and a picking rail 5a, which is provided on the upper side of the handling chain, holds the grain culm by a grip. Such a feed chain 5 is a chain lens.
Together with the lever, it is configured to be capable of swinging and opening / closing about a vertical support shaft provided on the starting end side.

The processing chamber 12 is arranged side by side on one side of the handling chamber 11 and receives a processing object sent from the handling chamber 11 through the dust-sending port 18 and processes it while transferring it to the axial rear side. 7 is mounted on the inner shaft. In addition, this processing chamber 12
Is composed of front and rear side walls 19, 20, a processing cylinder case 21, etc.,
A processing cylinder receiving net (processing cylinder concave 22) is stretched at least in the lower half of the inside of the processing chamber so that the grain that has undergone the deflocculation process leaks to the lower sorting section. .
The dust-disposal products such as straw chips are discharged through the dust-exhaust port 23.

The processing chamber 12 is the treatment chamber 11
On the other hand, it is configured so that it can be opened and closed by swinging outward with the fried grain discharge cylinder 16 of the grain tank 15 as the center of rotation. The fried food discharge cylinder 16 is firmly held by a machine frame. Therefore, the Glen tank 15 and the working machine 9
Also in the above, the fried food discharge cylinder 16 is supported and configured so as to be capable of swinging and opening and closing around the rotation center.

In the processing chamber 12 shown in FIGS. 4 to 6, a part of the concave portion 22 covering the outer periphery of the processing cylinder 7 or a part of the processing cylinder case 21 is divided and the spindle 24 is provided. Opening and closing case 21a is configured so as to swing around and open and close.
Is provided. Therefore, when the grain to be removed is a wet crop, by opening the opening / closing case 21a, the dust is discharged to the swing sorting shelf below the middle portion without being sent to the end portion of the processing cylinder. can do. for that reason,
The processing cylinder concave is not clogged, and the loss of grains discharged to the outside of the machine can be minimized. In the case of a normal crop, the opening / closing case 21a is closed, and the dust is sent to the end of the processing cylinder as usual and discharged from the dust outlet 23. If the dust control in the handling room and the opening degree control by the opening / closing case 21a are interlocked, it is possible to balance the dust transfer in the handling room and the processing capacity in the processing room. It does not clog indoors and can improve threshing capacity.

In the figure, reference numeral 25 designates a swing selecting device, which comprises a Glen pan 26, a chaff sheave 27, a straw rack 28, a Glen sieve 29 and the like. Reference numeral 30 is Kara, 31 is a suction dust collecting fan, 32 is a first receiving trough, and 33 is a second receiving trough.

[0012]

[Other Embodiment] The embodiment shown in FIGS. 7 to 8 will be described. A processing cylinder 7 is provided in parallel with the processing cylinder 6 in the processing chamber, and a rear side wall 20 of a processing chamber 12 in which the processing cylinder is internally mounted is located rearward of the processing chamber 11, and a rear side wall 20 of the processing chamber and a threshing left side wall. The stiffening member 35 that connects with
Discharging straw carrying rod 10 for 0 discharging straw conveying chain 10a
It is provided below b. The feed chain 5, together with the chain rail, is configured to be capable of swinging and opening / closing around a vertical axis 36 provided in the start end side in the vertical direction. Reference numeral 37 is a lock hook, and 38 is a lock pin, which is configured to engage and lock the lock hook 37 with the lock pin 38 when the feed chain 5 is closed.

To improve the maintenance, it is difficult to secure the rigidity of the handling chamber and the treatment chamber due to the feed chain opening, the handling cylinder cover opening, etc., and the frame is distorted to cause a gap defect between the handling tooth and the receiving net. , Interference, unhandled loss, etc. are problems. Therefore, since the processing chamber rear side wall 20 and the threshing left side wall 34 are connected by the reinforcing member 35 as described above, rigidity can be ensured because the threshing machine frame does not open. Reinforcing member 35
And the feed chain lock portion are fastened via the threshing left side wall 34, the fall of the feed chain at the time of clogging can be prevented and the rigidity can be secured. The reinforcing member is a drainage straw holding rod 10.
Since it is located below b, it does not hinder the transport of the discharged straw.
