Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to the structure of the intake part of an air cleaner in a work vehicle in which water does not enter from the intake port of the air cleaner. A protective cover, which is arranged inside the vehicle body through a plate, exposes the intake port of the intake pipe connected to the air cleaner to the outside of the shield plate, and attaches a protective cover to the upper and lateral sides of the intake port to the shield plate. The structure of the intake portion of the air cleaner in the working vehicle.

[Conventional technology]

Conventionally, in work vehicles such as water-sprayers and lawn mowers, the engine, air cleaner, and other driving parts are placed inside the vehicle body while being shielded by a shielding plate, while the air cleaner is inhaled so that clean outside cool air can be drawn in. The mouth is exposed from the shield plate to the outside. Then, in order to prevent water and dust from being sucked in as much as possible from the intake port of the air cleaner, conventionally, a protective cover is attached to the shielding plate so as to cover the intake port of the air cleaner so that the upper and lateral sides are closed and only the lower part is opened. Things are being considered.

[Problems to be solved by the invention]

However, for example, in a water sprinkler, the return water spouted, and in the case of a lawn mower, water droplets attached when washing the machine body adheres to the top and side surfaces of the protective cover, and these water droplets adhere to the side plates. It may flow down along the side plate and collect on the lower edge of the side plate. In such a case, a water drop may be sucked from the intake port together with the intake of air by the air cleaner.

On the other hand, it is conceivable that the side plate of the protective cover is formed to be long, but if it is configured in this way, there is a drawback that the suction resistance of air increases and the arrangement of other members is restricted, and there is room for improvement. was there.

The present invention has been made by paying attention to the above-mentioned circumstances, the suction resistance is not particularly increased, the arrangement of other members is not restricted, and the suction of water droplets adhering to the protective cover is prevented by a simple structure. The purpose is to prevent.

[Means for solving problems]

That is, in order to achieve the above-mentioned object, the air cleaner intake structure of the working vehicle according to the present invention has an engine and an air cleaner disposed inside a vehicle body through a shield plate, and an intake pipe of an intake pipe connected to the air cleaner. In the structure of the air intake part of the air cleaner in a work vehicle in which the mouth is exposed to the outside of the shielding plate, and a protective cover that covers the upper and lateral sides of the intake port is attached to the shielding plate, the protective cover is attached to the outside of the lower edge of the protective cover. It is characterized in that a gutter part for draining down the water is provided over substantially the entire circumference, and a drainage part formed on the lower inclined side of the gutter part is located in the vicinity of the shielding plate.

The operation and effect of this characteristic configuration are as follows.

[Action]

If water droplets attached to the top or side of the protective cover flow down along the side plate, they can be collected and drained down the gutter formed on the lower edge of the side plate, and water droplets will collect on the lower edge of the protective cover. You can eliminate the situation. Then, the water flowing down the trough is discharged from the drainage part, and the discharged water flows down along the shield plate, so that the discharge of water from the drainage part is scattered. Without flowing smoothly down.

[Effect of device]

As a result, unlike the conventional case where the side plate of the protective cover is formed to be long, the suction resistance does not increase and the arrangement of other members is not restricted, and the water droplets are sucked into the air cleaner. With a simple structure, it is possible to prevent the suction from the inside through the mouth, and it is possible to reliably flow down by being transmitted through the shield plate.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 4 shows a remote-controlled water discharge vehicle as an example of a work vehicle. This sprinkler has an engine (1), radiator (11),
A prime mover (12) equipped with an air cleaner (2) and the like is mounted, and a remotely controlled water discharge part (9) is provided in the front-rear direction intermediate part of the vehicle body (8), and a hose storage part is provided at the rear part of the vehicle body (8). (10) is provided, and a hose connecting portion (13a) connected to the water discharge portion (9) is provided below the storage portion (10).

Hose (13) housed in the hose housing (10)
Is discharged from the storage part (10) and is connected to a pump car equipped with a water tank and a water supply pump, so that the water discharge part (9)
The water can be discharged from it.

As shown in FIG. 3, both sides of the radiator (11) are arranged so as to prevent outside water and dust from entering the engine (1) and the air cleaner (2) arranged in the front part of the vehicle body (8). A shielding plate (3) is attached between the vehicle body cover (14) and the vehicle body cover (14). Then, the tip of the intake pipe (4) connected to the air cleaner (2) penetrates through the shield plate (3) and is projected to the outside, so that the upper end and the lateral periphery of the protruding end of the intake pipe (4) are A box-shaped protective cover (5) having an opening at the bottom so as to cover is attached to the shield plate (3). More specifically, as shown in FIGS. 1 and 2, a trumpet-shaped air introduction pipe (15) is provided around the tip of the intake pipe (4) protruding outward from the shielding plate (3). , The intake port (4a) is formed here. Extension dimension L ₁ of the side plate (5a) of the protective cover (5) extending downward from the lower edge of the intake port (4a)
Is set to be more than twice the inner diameter of the intake pipe (4). Further, a gutter (6) is formed in a series by bending outside the lower edges of the side plate (5b) on the front side and the side plates (5a) on both sides of the protective cover (5). The gutters (6) on the side plates (5a) on both sides have the shield plate (3) side inclined downward, and the shield plate (3).
A part of the side trough part (6) is cut out to form a drainage hole (7) as a drainage part. As shown in FIG. 1, the drain hole (7) has a cutout (6) in which the slanted end of the gutter (6) and the shield plate (3) face each other. It is provided in the opened state.

Therefore, an intake passage having a downward opening is formed in the protective cover (5) so that suction can be performed from the intake port (4a) through the intake pipe (4), and the outer surface of the protective cover (5). Water droplets adhering to the water flow down along the side plates (5a) and (5b) of the protective cover (5), are stored in the trough (6), and flow down downward from the water drain hole (7), which in turn shields the water. It flows down the plate (3).

[Another embodiment]

 It can also be applied to lawnmowers as a work vehicle.
