7) are arranged close to each other at the front of the grain tank (14), and the lock pin (27) is fixed to the grain tank (14), and the input shaft (33) and the output shaft (3) by the butt clutch (36).
5) The connection of 5) can be easily confirmed, preventing the butt clutch (36) from being disengaged by the rotational force of the output shaft (35) or generating or damaging abnormal noise due to the eccentricity of the engaging portion, and the output of the engine (13a). From the machine-side intermediate drive case (34) to the transverse feed auger (19), and with the threshing unit (4) stopped, the transverse feed auger (19) and the vertical feed auger (2).
0) to take out the grains in the grain tank (14),
Threshing unit (4) is configured to prevent generation of drive noise or wasteful fuel consumption, and to improve handling operability. On the right inner wall surface (14a) of the grain tank (14), a lower limit for detecting the amount of stored grain is set.
Intermediate / upper limit sensors (37), (38), and (39) are provided, and an indicator (4
0) is provided above the front wall (14b) of the grain tank (14). These sensors (37), (38), (39)
Each connection cord (41) of the indicator (40) is disposed along the tank right inner wall surface (14a), and the tank rear wall (14) near the auger cylinder (22).
c) through the cord insertion hole (42) opening in the tank (1).
4) The power supply side of the cord (41) is led out to the outside, and the displacement amount of the cord (41) without pulling or loosening at the time of the rotation operation about the auger cylinder (22) of the tank (14). Is configured to be suppressed. (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 constructed as described above, and stores the grains that have been threshed in the reaping and threshing section (4) in the reaping section (7) in the kernel tank (14). By driving the augers (19), (20) and (21), the grains in the grain tank (14) are taken out of the machine. 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) is unlocked as shown by the phantom line 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
3) and the drive output shaft (35) on the machine side are easily connected and disconnected by a one-touch operation by abutting or releasing the clutch (36). In the above embodiment, the tank (1
4) The drive input shaft (33) and the drive output shaft (3
5) is connected by a butt clutch (36). However, any structure can be used as long as the input shaft (33) can allow a rotation locus drawn by the input shaft (33) around the auger cylinder (22). (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. As is apparent from the above embodiment, the present invention provides a grain tank (1) on a machine (3) on one side of a threshing unit (4).
4) provided rotatably in a substantially water <br/> horizontal direction by a fulcrum shaft (23a) and the bearing bore (24), disengageably one-touch connection by the rotation of the substantially horizontal direction of the grain tank (14) A clutch (36) is provided , and a one-touch coupling clutch (36) is connected.
And remove the transverse auger (19) at the bottom of the grain tank (14)
While driving, the transverse auger (19) and the auger (1)
Drive to the connecting part of vertical feed auger (20) to be connected to 9)
In a combine where a transmission case (23) is provided,
Drive transmission case (2
The lower surface of 3) is lower than the upper surface of the machine base (3) to transmit the drive.
Insert the lower surface of the case (23) into the machine base (3),
The drive transmission case (2) is inserted into the bearing hole (24) provided in the base (3).
3) The fulcrum shaft (23a) on the lower surface is higher than the upper surface of the machine (3).
It is rotatably fitted at a low position and has a bearing hole (24).
To provide the outside of the machine base (3)
And the installation of a fulcrum shaft on the machine base (3)
Drive transmission case (23) on machine stand (3)
Auger on the top of the machine (3) just as much
(19) can be approached and the grain tank (14)
Grain tank by reducing the distance between the lower surface and the machine (3) upper surface
(14) can be stably supported, and
The one-touch coupling clutch (3
6) is arranged and the one-touch coupling clutch (36) is engaged.
Grain tank (1) to secure the strength necessary for smooth disengagement
4) can trigger supports, supporting the grain tank (14)
Simplified holding structure or one-touch coupling clutch (36)
It is capable of performing such simplification of the disengaging operation.
