Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides an elastic seal member between the left and right ends of the radiator and the side covers below the bonnet to block backflow of cooling exhaust air from the radiator. The present invention relates to the structure of the driving part of the farm work vehicle.

[Conventional technology]

Generally, in the above agricultural work vehicle, the side cover is formed in a concavo-convex shape in order to reinforce the strength and to meet design requirements. Then, the conventional elastic seal member (21) is attached to the side portion of the radiator (12) and its outer portion is provided with a gap on the side portions of the side covers (15) and (15) as shown in FIG. 6, for example. Roughness was formed to make contact with each other.

[Problems to be solved by the invention]

The seal member is provided in order to prevent the hot exhaust air after passing through the radiator from returning to the engine compartment side and prevent the cooling efficiency of the radiator from decreasing, but the shape thereof is uneven. For this reason, there are cases where the unevenness of the side cover does not exactly match the unevenness of the side cover due to a dimensional error during assembly, and a gap is formed between them, and the expected cooling performance may not be obtained.

An object of the present invention is to block a gap between a side portion of a radiator and a side cover so that a good cooling effect can be obtained.

[Means for solving problems]

The features of the present invention are, in the driving part structure of the agricultural work vehicle having the above-described configuration, the elastic seal members are attached to the radiator on both left and right sides, and the elastic seal members are embedded in the inner surfaces of the side covers along the vertical direction. The vertical plate is fixed, and its action and effect are as follows.

[Action]

In other words, since the portion in contact with the elastic seal member is the vertical plate, it is not necessary to form the seal member in an uneven shape even when the side cover is formed in an uneven shape, and it is possible to provide the seal member in a flat stripe. In addition, since the vertical plate is designed to be bite into it, the assembling error in the front-rear direction and the left-right direction can be absorbed.

[Effect of device]

Therefore, the structure can be shielded without gaps between the side portions of the radiator and the side cover by a simple structural improvement, and even if an assembly error occurs, there is no gap, so that the cooling efficiency of the radiator is reduced. It can be prevented. Moreover, the vertical plate also has the effect of reinforcing the strength of the side cover.

〔Example〕

FIG. 5 shows an agricultural tractor which is an example of the agricultural work vehicle according to the present invention. This tractor is equipped with a pair of left and right wheels (1) and (2) on the front and rear, respectively, and also has a hood on the front of the machine.
(3) The driving part (A) is arranged on the inner side.

Next, the structure of the drive part (A) will be described. As shown in FIG. 4, the engine (6) is mounted and fixed on the fuselage frame (4) inside the bonnet (3) via the rubber vibration isolator (5), and on the side of the engine (6). A muffler (7) is provided, and a fuel tank (8) is arranged in the upper rear part of the engine (6).
A cooling air intake (9) is formed above the engine (6) of the bonnet (3), and the fuel tank (8) is located below the intake (9) and above the muffler (7). A fuel tray (10) is provided to prevent fuel from accidentally falling onto the muffler (7) through the intake port (9) during refueling of the fuel. In addition, the exhaust pipe (1) extending from the muffler (7) toward the front side
The middle part of 1) is formed in a bellows structure to prevent the vibration of the engine (6) from being transmitted to the tip of the exhaust pipe (11).

A radiator (12) for cooling the engine is provided on the front side of the engine (6), and cooling wind generation fans (13a), (13b) are provided in front of and behind the radiator (12), and these fans (13
a) and (13b) are rotated by the output of the engine (6), the rear fan (13b) blows air toward the radiator (12), and the front fan (13a) blows the radiator (12). It is configured to suck the cooling exhaust air from.
The exhaust air sucked by the front fan (13a) is configured to be discharged outside the machine from the front grill (14) at the front end of the machine body.

As shown in FIGS. 1 to 3, the bonnet (3)
The lower side covers (15), (15) of the engine are bent in an uneven shape in order to reinforce the strength and to meet the design requirements, and the cooling exhaust air flows above and below the radiator (12) on the engine. Band-shaped elastic seal members (16), (16) made of sponge are attached to prevent blowback to the chamber (S) side. The side cover (15), elastic seal member (16) of (15),
Vertical plates (17) and (17) into which the seal members (16) and (16) are inserted are fixed to the position (16) in the vertical direction. The edges of the vertical plates (17), (17) on the inner side of the body are formed in a straight shape in the vertical direction, and are configured so that the sealing members (16), (16) are easily inserted in the straight shape.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the structure of the accompanying drawings by the entry.
