Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine grain tank apparatus in which grain culms cut by a cutting section are shredded and sorted by a threshing section to store only sized grains.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Laid-Open No. 59-31833, there has been a system in which a grain carrying-out device of a Glen tank and a Karako shaft on the machine side are connected by a belt.

[0003]

However, according to the above-mentioned means, when the grain tank is opened around the vertical axis to the outside of the fuselage or is stored inside the fuselage, the belt is removed each time. Alternatively, there is a troublesome work of having to perform the mounting operation.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a grain tank for storing grains that have undergone threshing is rotatably supported to the outside of the machine body through a vertical axis, and a drive input portion of the tank is one-touched. It is configured to be connected to the drive output section on the machine side so that it can be detached and attached, and when the grain tank is opened to the outside of the machine or stored inside the machine, the connection release or connection operation of the drive connection section is one-touch This makes it easy to open and store this tank outside or inside the machine body, which makes various maintenance and inspection convenient.

As shown in FIGS. 4 and 5, the grain tank (14) feeds a grain transverse feed auger (19) at the bottom and a grain feed from the transverse feed auger (19) at the rear. A vertical feed auger (20) is further provided on a horizontal discharge auger (2) for taking out grains from the vertical feed auger (20) outside the machine.
1), wherein the grain tank (14) is provided so as to be rotatable outwardly around an auger cylinder (22) of the auger (20) which is a vertical axis. The lower end shaft portion (23a) of the drive transmission case (23) with the vertical feed auger (20) is used as the bearing member (24) of the machine base (3), and the middle of the vertical feed auger (20) is used as the engine portion (13). ) It is rotatably supported by a tube receiving member (25) on the front wall, and the front side of the grain tank (14) can be opened outward.
In addition, the machine base (3) when storing the grain tank (14) inside the machine
The lock holder (28) of the grain tank (14) is removably fixed to the lock plate (26) via a lock pin (27), and the lock fitting (4) of the inner wall (4a) of the threshing unit (4). 29) Grain tank (1) via lock pin (30)
4) Fixing the latch (31) on the inner wall so that it can be freely disengaged,
The tank (14) is configured to maintain its position.

Further, the output of the engine (13a) of the engine section (13) is transmitted to an input shaft (33) which is a drive input section interlockingly connected to the transverse feed auger (19) via a pair of bevel gears (32). An output shaft (35), which is a drive output part of the machine-side intermediate drive case (34), is connected and connected via a butt clutch (36) so that the input shaft can be connected or disconnected when the tank (14) is stored or opened. (33)
And the output shaft (35) can be connected or disconnected with a single touch. The clutch (36)
Are connected so as to allow the rotation of the grain tank (14), and the connection or disconnection of the tank (14) is performed without any trouble when the tank (14) is stored or opened. .

By the way, on the right inner wall surface (14a) of the grain tank (14), there is a lower limit for detecting the storage amount of grain.
An intermediate / upper limit sensor (37), (38), (39) is provided, and an indicator (4) for displaying these stored amounts is provided.
0) is provided above the front wall (14b) of the grain tank (14). Moreover, these sensors (37) (38) (39)
The connection cords (41) of the indicator (40) are arranged along the tank right inner wall surface (14a), and the tank rear surface wall (14) near the auger cylinder (22).
c) through the cord insertion hole (42) opening in the tank (1).
4) The power source side of the cord (41) is led out to the outside, and the amount of displacement of the cord (41) is not pulled or loosened during the rotation operation around the auger cylinder (22) of the tank (14). Is configured to suppress. (4
Reference numeral 3) denotes an auger cylinder of a lateral discharge auger (21) which is connected to and supported by the auger cylinder (22) so as to be undulating and rotatable.

The present embodiment is configured as described above, and the grains that have been threshed by the mowing unit (4) and the threshing unit (4) are stored in the grain tank (14), and when necessary. By driving each auger (19) (20) (21), the grain in the grain tank (14) is taken out of the machine.

Thus, the threshing section (4) and the grain tank (1
When checking the drive transmission system from the engine (13a) during 4), the lock pins (27) and (30) are unlocked, and the auger cylinder (22) as shown in the phantom state in FIG. , The grain tank (14) is pivoted outward to open, and as a result, the extra space around the drive transmission system is enlarged, and inspection work and the like can be facilitated. When the tank (14) is stored or opened, the drive input shaft (3) of the tank (14) is
3) and the drive output shaft (35) on the machine side can be easily connected and disconnected by one-touch operation by abutting or releasing the clutch (36).

In the above embodiment, the tank (1

(33) Any of the friction method of (35) in which the opposing surfaces are brought into surface contact or a meshing method such as coupling may be used.

[0012]

As is apparent from the above embodiments, according to the present invention, the grain tank (14) for storing the threshed grains is rotatably supported to the outside of the machine body through the vertical axis (22). Since the drive input section (33) of the tank (14) is connected to the machine-side drive output section (35) so as to be detachably operated with one touch, the grain tank (14) is opened to the outside of the machine or When it is housed inside the machine body, the operation of attaching and detaching the drive unit becomes extremely easy, and the efficiency of maintenance and inspection work around the tank (14) is improved by opening the tank (14) and facilitating the storage work. It has a remarkable effect.
