Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work vehicle such as a tractor or a riding lawn mower, and more particularly to a vehicle body in which a main clutch housing directly connected to an engine and a gear transmission case at the rear of the vehicle body are connected by a hollow housing. The present invention relates to a structure for assembling a steering handle and a front view arch-shaped frame supporting a rear part of an engine bonnet.

2. Description of the Related Art Conventionally, in work vehicles such as tractors,
When assembling the steering handle and the arch-shaped frame that supports the rear end of the engine bonnet to the aircraft, on the upper surface of the hollow housing that connects the main clutch housing directly connected to the engine and the gear transmission case at the rear of the vehicle body. While mounting the steering post, a bracket is provided on the front upper surface of the hollow housing, and a horizontal frame for mounting the arch frame along the lateral direction of the machine body is mounted on the bracket, and the horizontal frame for mounting the arch frame is attached to the engine. A front arch-shaped frame that supports the rear end of the bonnet is connected.

[0003]

The steering post and the arch-shaped frame supporting the rear end of the engine bonnet in front view are attached to the body at a fixed relative distance, but the fixed distance is maintained. Since precision is required for all assembling, the assembling is troublesome.

Further, since the steering post is simply attached to the upper surface of the hollow housing via vertical bolts, there is a disadvantage that the supporting strength of the steering post is weak.

An object of the present invention is to eliminate the troublesome assembling and to increase the support strength of the steering handle.

[0006]

A characteristic feature of the present invention for achieving the above object is to provide a working vehicle in which a main clutch housing directly connected to an engine and a gear transmission case at a rear portion of a vehicle body are connected by a hollow housing. At
The front part of the hollow housing is provided with a steering post support base that can be connected to the back surface of the main clutch housing, and the steering post support base has a front view arch type frame that supports the steering post and the rear end of the bonnet. The point is that the integrated units are connected via front and rear and upper and lower bolts.

[0007]

With the unitization, the steering post and the arch-shaped frame for supporting the rear end of the engine bonnet can be attached to the machine body while maintaining a constant relative distance.

Also, the steering post is connected to the steering post support base connected to the hollow housing through front and rear and upper and lower bolts, or, for example, compared with the case where only the vertical bolts are connected. Then, the position is fixed in two directions and it is firmly supported.

[0009]

As a result of the above construction, the front view arch type frame for supporting the steering post and the rear end of the engine bonnet with respect to the machine body can be accurately assembled.

Further, since the steering post is attached to the steering post support base through the bolts in the front and rear and up and down directions, the support strength of the steering post is increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the whole of a tractor, which has a main clutch housing 2 directly connected to an engine 1 and a gear transmission case 3 at the rear of the vehicle body with a U-shaped opening facing downward. It is composed of a monocoque type body connected via a hollow housing 4.
A battery 6 and a radiator 7 are mounted on a front frame 5 projecting forward from the engine 1, a fuel tank 8 is arranged above and behind the engine 1, and these are covered with an engine bonnet 9. Then, a steering wheel 11 is provided on a control panel 10 behind the engine bonnet 9, a driver seat 12 is provided above the mission case 3, and the driver seat 12 is provided.
A lops frame 13 that protects the operator when the machine falls down is provided in a state of extending upward from the rear end of the mission case 3.

The fuel tank 8 is mounted on an arch-shaped frame 14 in a front view in a state of partitioning an engine room in a hood 9 and a control panel 10 of a control section in the front-rear direction. The rear end of the engine hood 9 and the front end of the control panel 10 are connected to each other.

The engine bonnet 9 is composed of an upper cover 9A which is supported on the arch-shaped frame 14 so as to be able to swing upward and downward about a horizontal axis P ₁ and a lower cover 9B which is fixed to the machine body. ing.

Next, the mounting structure of the front view arch type frame 14 supporting the steering post 11A and the rear end of the bonnet 9 to the machine body will be described.

As shown in FIGS. 2 to 4, the front view arch-shaped frame 14 supporting the steering post 11A and the rear end of the bonnet 9 is unitized as one assembly, and in the unitized state, the machine body is formed. Installed on.

That is, a pair of left and right front and rear frames 15 extending from the side surface of the steering post 11A to the front of the body,
The front end portions of 15 are connected to each other via an auxiliary plate extending in the lateral direction of the machine body, and the horizontal frame 16 for mounting an arch frame extending in the lateral direction of the angle machine is connected to the auxiliary plate via bolts in the front-rear direction. The horizontal frame 16 for mounting the arch frame is connected to the front arch-shaped frame 14 via vertical bolts to form a unit A as one assembly.

Then, at the front of the hollow housing 4,
A steering post support base 17 that can be connected is provided on the back surface of the main clutch housing 2.

The steering post support base 17 is a vertical wall 17 connectable to the back surface of the main clutch housing 2.
a and a pedestal 7b capable of connecting the front and rear frames 15, 15 of the unit A and a tongue piece 17c capable of connecting the rear peripheral wall of the steering post 11A.

Then, the steering post support base 1
7, the rear surface of the steering post 11A of the unit A is connected via front and rear bolts 18 and 18, and a pair of left and right front and rear frames 15 and 15 is connected via vertical bolts 19 and 19. .

In the tractor, as shown in FIG. 5, the ROPS frame 13 is provided with a detachable basket 20 into which agricultural machinery such as a scoop and a hoe can be placed.

The car 20 is a hook 2 of a connecting fitting 21 which is fastened to the rope frame 13 by bolts.
It is detachably attached to 2.

[Other Embodiments] The work vehicle may be a riding lawn mower.
