Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an engine device that drives various parts such as a traveling part of a combine and a threshing part.

[0002]

[Prior art]

 Normally, the air cleaner is integrally attached to the outside of the engine, and the intake port is exposed to the outside air so that the outside air is directly taken in.

[0003]

[Problems to be solved by the device]

 For this reason, in this type of combine operation in which a large amount of dust etc. is generated, there is a drawback that the suction rate of dust is high and frequent cleaning and replacement are required to maintain stable performance. .

[0004]

[Means for Solving the Problems]

 Therefore, according to the present invention, the inside of the side column disposed on the side of the driver's seat is formed as an air cleaner suction air passage for taking in the outside air of the air cleaner of the engine, and the suction column formed easily and compactly in the side column. The clean air from the air passage is taken in to keep the performance of the air cleaner stable for a long period of time.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a front view of the engine, Fig. 2 is a side view of the combine as a whole, and Fig. 3 is a plan view of the same. In the figure, (1) is a track frame equipped with a traveling crawler (2), and (3) ) Is a machine frame installed on the track frame (1), (4) is a threshing unit in which a feed chain (5) is stretched on the left side and a handling cylinder (6) and a processing cylinder (7) are built in, 8) is a mowing section equipped with a cutting blade (9) and a grain culm transport mechanism (10), (11) is an straw processing section that faces the end of the straw chain (12), and (13) is a driver's seat (14). ) And a driver's cab provided with a driving operation unit (15), (16) an engine arranged substantially below the driver's seat (14), and (17) a grain barrel from the threshing unit (4). (18) is a grain tank that is fed through, (19) is a grain discharge conveyor that takes out the grain in the grain tank (17) to the outside. , And configured to perform continuously reaping and threshing work.

As shown in FIGS. 4 to 8, a seat column (20) having a substantially L shape in a side view for installing the driver's seat (14) and a right side column (21) are integrally provided. The lower end of the side column (21) is supported on the right side of the machine base (3) via the front and rear fulcrum shafts (22) and (23) so as to be freely open to the right outside. A radiator (24), a fan for cooling the radiator (25), which is located below the front plate (20b) and to the left of the side column (21), and which has a portion (20a) and a front plate (20b). These are arranged in the order of the engine (16).

The side column (21) has an inside formed into a hollow outside air intake suction air passage (26). An outside air right suction port (27) is formed in the upper half of the right outer wall of the column (21). In addition, the outside air left suction port (28) is opened at the upper end of the left outer wall of the column (21), and at the same time, the internal cavity is expanded below the upper plate (20a) of the column (21) toward the inside of the machine. The column overhanging portion (21a) is integrally formed, and the bypass air passage (26a) for supplying cooling and combustion air to the radiator (24) and the engine air cleaner (29) inside the overhanging portion (21a). ) Is formed so that the suction air passage (26) and the detour air passage (26a) are communicated with each other through the intake port (30) on the lower side of the column (21), and the left side of the overhang portion (21a) is formed. Each suction port (2) of the column (21) is opened from the opening (31) opened on the outer wall. 7) The radiator (24) is blown with the outside air taken in from (28) to radiate and cool it.

As shown in FIGS. 7 to 8, the partition walls (21b) and outer wall (21c) of the plate portions (20a) (20b) and the overhanging portion (21a) are located above the opening (31) in a side view. An air passage guide (33) having an intake air passage (32) for the air cleaner therein is provided in the isolated air passage (26b) above the detour air passage (26a) surrounded by and and the guide (33) The intake air passage (32) communicates with the bypass air passage (26a) through the rear end opening (34), and the intake pipe from the cleaner (29) is introduced into the air passage (32) at the front end of the guide (33). The suction port (35a) of (35) is exposed through the guide port (33a) outside the overhanging portion (26a), and the cleaner (29) is passed through each air passage (26) (26a) (32). The outside air is taken in and clean air after removing impurities such as dust is connected (3 6) is supplied to the engine (16).

As shown in FIG. 4, the air cleaner (29) is located behind the rear cover (37) provided at the rear end of the column top plate (20a) and substantially above the radiator (24) and fan (25). It is fixedly supported laterally in the lateral direction on the body side by a suspension member (38) from above.

Further, (39) is a lock pin for storing the side column (21) in the cabin.

This embodiment is configured as described above, and the double air passages (26) (26a) for supplying air to the radiator (24) and the air cleaner (29) are provided in the side collum (21). Since the outside air suction ports (27) and (28) are formed on the upper end side of the column (21) far away from the mowing part (8) and the engine (16), the mowing part (8) is formed. Direct intake of outside air containing a large amount of dust generated by, etc., or outside air warmed by the engine (16) is prevented, and at the time of distribution of each air passage (26) (26a), Due to the suction air passage (26) flowing from the upper side to the lower side and the bypass air passage (26a) flowing from the lateral direction and from the lower side to the upper side, even if impurities are mixed in the outside air in the air passage (26), this circulation On the way, only the impurities are naturally lowered The air is separated and removed, and only pure air is supplied to the radiator (24) and the cleaner (29) to prevent early clogging of the filter and the like.

Particularly in the case of the cleaner (29), the intake air passage (32) formed by the air passage guide (33) is further provided in the isolation air passage (26 b) above the bypass air passage (26 a) to improve the cleanliness. It is possible to supply clean outside air and maintain its performance for a long period of time.

[Effect of device]

 As is apparent from the above-described embodiments, the present invention has a suction column for an air cleaner that takes in the outside air of the air cleaner (29) of the engine (16) inside the side column (21) arranged on the side of the driver's seat (14). Since it is formed in the air passage (26), clean air with a small amount of dirt is taken from the suction air passage (26) which is formed simply and compactly by effectively utilizing the side column (21), and the air cleaner (29 It is very effective to maintain stable performance for a long period of time).
