Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a normal combine grain tank device for cutting grain such as rice, wheat and soybeans for threshing.

"Conventional Technology" Conventionally, the Japanese Utility Model Publication No. 60-85136 and the Japanese Utility Model Publication No. 61-69941.
As disclosed in Japanese Patent Laid-Open Publication No. 2004-163, there is a technique in which grains taken out from a plurality of outlets of a grain tank are merged and the merged grains are discharged to the outside of the machine by a discharge conveyor.

[Problems to be solved by the invention] In the conventional technology, a plurality of outlets are opened in an auxiliary tank, and the grains from the plurality of outlets are merged in the auxiliary tank. Since the take-out port cannot be easily arranged, it is not possible to easily increase the capacity of the grain tanks provided with the take-out port in the left-right direction, and the weight on one side outside the machine increases or decreases due to the increase or decrease of the grain in the grain tank. There is a problem that the left-right weight balance tends to change.

"Means for Solving the Problem" Therefore, the present invention provides a grain tank device of a combine, in which the grain of the threshing portion is taken out to the grain tank and a discharge conveyor for discharging the grain of the grain tank to the outside of the machine is provided.
Plural outlets of grain tanks are provided on both left and right sides of the threshing section in which the handling cylinder is installed, and take-out conveyors for delivering the grains in the grain tanks are arranged inside the respective take-out ports, and the take-out ports are provided. A grain conveyor from the grain tank that was taken out from the grain tank is merged on one side of the threshing unit and then fed to the discharge conveyor.Since multiple grain outlets are distributed to the left and right sides of the threshing unit. , The grain tanks can be added to the left and right to increase the capacity easily, and it is possible to eliminate the problem that the grain tank shifts to one side outside the machine and the left and right weight balance of the machine body changes, and the grain at each outlet Since the grains are merged and fed to the discharge conveyor, it is not necessary to discharge the grains in the grain tank from both sides of the machine body, and it is possible to easily improve the grain collecting workability.

In addition, between the driver's seat rear side having the driver's seat and the grain tank front side, a confluent conveyor is extended in the left-right direction on the upper surface of the threshing unit, and the driving unit and the grain tank located higher than the threshing unit are By avoiding this, the merging conveyor can be arranged compactly, and the merging conveyor can be easily brought close to the driving unit such as the threshing unit to simplify the drive structure.

[Effect of Device] As is apparent from the above-described embodiments, the present invention takes out the grains of the threshing unit (4) to the grain tank (7) and discharges the grains of the grain tank (7) to the outside of the machine. In a combine grain tank device equipped with a conveyor (14),
Plural outlets (7b) and (7b) of the grain tank (7) are provided on both the left and right sides of the threshing section (4) in which the handling cylinder (5) is installed, and the grains in the grain tank (4) are sent out. The take-out conveyors (27) (27) are respectively arranged inside the take-out ports (7b) (7b), and the grains in the grain tank (7) taken out from the take-out ports (7b) (7b) are threshed. The part (4) is provided with a merging conveyor (33) (34) that feeds the discharge conveyor (14) after merging on one side, and a plurality of outlets (7b) (7b) of the grain tank (7). Since the grain is distributed to the left and right sides of the threshing unit (4), the grain tank (7) can be expanded in the left and right direction to easily increase the capacity, and the grain tank (7) is offset to one side outside the machine. It is possible to eliminate the problem that the left and right weight balance of the aircraft changes, and each outlet (7b)
Since the grains in (7b) are merged and sent to the discharge conveyor (14), it is not necessary to discharge the grains in the grain tank (7) from both sides of the machine body, and it is easy to improve the grain collection workability. Can be achieved.

In addition, between the rear side of the operation part (11) having a driver's seat and the front side of the grain tank (7), the converging conveyors (33) (34) are extended in the left-right direction on the upper surface of the threshing part (4). Thus, it is possible to compactly arrange the merging conveyors (33) and (34) by avoiding the operation unit (11) and the grain tank (7) located higher than the threshing unit (4), and the driving unit such as the threshing unit (4). By making the merging conveyors (33, 34) close to each other, the drive structure can be easily simplified.
