Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combine for threshing grain culms cut by a mowing section in a threshing section, storing the threshed grains in a grain tank and carrying them around for harvesting work.

[0002]

[Prior art]

 Conventionally, combine combines a driver's control unit, a driver's seat in front of one side of the airframe, an engine under it and a grain tank behind it, or a driver's control unit, driver's seat, grain tank in the front, and then There was an engine on one side.

[0003]

[Problems to be solved by the device]

 In the above conventional technology, the grain tank is largely displaced from the front-rear center of gravity position of the machine in order to secure a space for mounting the engine, and the front-rear balance of the machine is not constant due to the weight change of the grain tank. There was a problem with performance.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention is one in which an engine, which is a heavy object, is disposed near the front and rear center of gravity of the combine airframe, grain tanks are disposed in front of and behind the engine, and an engine cover is formed integrally with the tank. We improved the wetland performance by distributing and storing the grains in the grain tanks in front of and behind the engine, and keeping the front and rear balance of the combine aircraft constant regardless of the weight change of the grain tank. It is a thing.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional explanatory view of a grain tank, FIG. 2 is an overall side view of the combine, FIG. 3 is a plan view of the combine, and FIG. 4 is a rear view of the combine, in which (1) is a left and right traveling crawler (2) ( 2) a track frame for mounting, 3) a machine base fixedly supported on the track frame 1, and 4) a feed chain 5 mounted on the left side and a handling cylinder 6 built-in. The threshing section, which is composed of (7), is supported by the machine base (3) so as to be able to move up and down, and has a cutting blade, a grain transfer mechanism, and the like. (8) is an ejector connected to the end of the feed chain (5). The straw cutter that faces the end of the straw chain (9), (10) the engine that drives each part of the combine, (11) the grain that is extracted from the threshing unit (4) that faces the fried cylinder (12). A grain tank for storing grains (13) is provided with a driver's seat (14) and a driving operation unit (15). A trapezoidal continuously with reaps culms before SL reaper (7), and configured to threshing process the cutting culms in the threshing section (4).

Further, the engine (10) is housed in an engine room case (17) mounted on the machine base (3) through the engine base (16) and is arranged at a front and rear center of gravity (O) of the combine machine body. The grain tank (11) is arranged in front of and behind the engine (10) in order to keep the front and rear balance of the combine machine body constant, and is arranged in front of the engine (10). The front tank portion (11a), the rear tank portion (11b) disposed on the rear side of the engine (10), and the communication portion (11c) for connecting the front and rear tank portions (11a) (11b) to each other at the upper portion are provided. It is formed integrally with the tank (11), and a shielding plate (19) is stretched below the bottom plate (18) of the communication part (11c) so that the rear plate (20) and the rear tank part (11a) of the tank part (11a) are extended. 11b) front plate ( 21), the bottom plate (18), the shielding plate (19), and the right side wall (22) of the tank, an engine cover (23) whose left side surface is opened is integrally formed on the tank (11). The engine room case (16) is supported inside the cover (23) at the center through the engine base (16).

Further, the front and rear tank parts (11a) (11b) are formed to have substantially the same capacity, and the bottom plate (18) of the communication part (11c) is formed in a mountain shape and the bottom plate (18) of the bottom plate (18) is formed. A grain charging port (24) for charging grains from above is opened on the left wall (25) of the tank, and the upper end side of the fried cylinder (12) is connected to the charging port (24). Now, the grains to be put into the tank (11) are distributed substantially evenly from the front and rear center of gravity (O) position of the combine aircraft to the front and rear tank parts (11a) (11b) by the chevron shape of the bottom plate (18). It is configured to be stored.

The tank (11) further has a horizontal grain feed auger (26) at the bottom and a vertical discharge auger (27) at the rear for vertically feeding the grain from the horizontal feed auger (26). Is equipped with an upper discharge auger (28) for taking out grains from the vertical discharge auger (27) to the outside of the machine, and the tank (11) is removed around the auger cylinder (29) of the auger (27) which is the vertical axis. The lower end shaft portion (31) of the drive transmission case (30) for the transverse feed auger (26) and the vertical discharge auger (27) is mounted on the machine base (3) in a rotatable manner on one side (right side of the machine body). An upper and lower cylinder receiver that is rotatably supported and is integrally attached to the rear wall of the tank (11), that is, the rear face plate (32) of the rear tank portion (11b), with the middle of the auger cylinder (29) of the vertical discharge auger (27). The members (33) (33) are rotatably supported, and the tank (11 1 ) The front side is configured to be open to the outside (right side of the machine body), and the engine room case (16) is exposed by opening the tank (11).

The bottoms of the front and rear tank parts (11a) (11b) are connected to each other by a grain discharge gutter (34), and the grains of the front tank part (11a) are discharged gutter (34) and a lateral feed auger (34). After being carried out to the rear tank section (11b) by 26), it is discharged to the outside of the machine.

[Effect of device]

 As is clear from the above embodiments, according to the present invention, the engine (10) is arranged at the front and rear center of gravity (O) of the combine airframe, and the grain tanks (11) are arranged before and after the engine (10). The engine is provided with an engine cover (23) integrally with the tank (11). The grain tank is distributed by storing it in the grain tanks (11) before and after the engine (10). The front-rear balance of the combine airframe can be kept constant regardless of the weight change in (11), and the combine airframe can always be run in a horizontal posture during wetland work, significantly improving wetland performance. Further, the engine cover (23) can be integrally formed with the grain tank (11), and it is not necessary to provide an engine cover (23) specially, and the cost can be reduced. Further, the engine (10) can be exposed only by opening the grain tank (11), and maintenance of the engine (10) and the like can be easily performed. The engine (10) can also be surrounded by grains to reduce noise. And so on.
