Abstract

PURPOSE:To simplify the installation structure of an openable bonnet cover. CONSTITUTION:Lower edge parts 4a and 4a of a bonnet cover 4 openably arranged to the upper part of a pair of car body frames on both sides 13A and 13A form an abutting edge which abuts against each of the upper surfaces of the car body frames 13A and 13A in a state to be positioned facing the upper surface thereof.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the body structure of a working vehicle such as an agricultural tractor.

0002

2. Description of the Related Art Conventionally, in working vehicles such as agricultural tractors, a bonnet that can be opened and closed is attached to a cover member that is installed in an upright position on the vehicle body frame, as disclosed in Japanese Patent Laid-Open Publication No. 2-31981, for example. A structure in which a cover is provided with the cover butted against the lower edge of the cover is known.

0003

[Problems to be Solved by the Invention] However, in the conventional structure described above, a bonnet cover that can be freely opened and closed is provided, and the cover member is provided separately, which requires time and effort to assemble this cover member to the vehicle body frame. In addition, it has the disadvantage that it is structurally complex and expensive.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a vehicle body structure for a working vehicle in which the structure for providing a bonnet cover can be simplified.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the vehicle body structure of a work vehicle according to the present invention has a lower edge portion of a bonnet cover which is disposed on the upper part of a pair of left and right vehicle body frames so as to be openable and closable. It is characterized in that it is formed on an abutting edge that faces and abuts against the upper surface of the vehicle body frame. The functions and effects of this characteristic configuration are as follows.

[0006]

[Operation] That is, the bonnet cover can be placed directly on the upper surface of the vehicle body frame with the abutting edges of the lower edges facing each other.

[0007]

[Effects of the Invention] Therefore, since the structure allows the bonnet cover to be mounted directly on the upper surface of the vehicle body frame, no special parts are required for mounting the bonnet cover, and the structure is extremely simple and inexpensive. It has now been possible to configure

[0008]

Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings.

FIG. 3 shows a riding lawn mower as an example of a work vehicle according to the present invention. This riding lawn mower is
A pair of left and right driving wheels 1, 1 that can be driven separately, and a steering rear wheel 2 that can change the direction of the axle around the vertical axis support the aircraft A so that it can run. It has a bonnet cover 4 and a grass collection container 5 at the rear, an engine 6 at the lower abdomen of the body A, and a mower 8 disposed at the front of the body A via a link mechanism 7.

At the back of the seat 9 in the driver's section 3, a safety frame 10 bent into a U-shape is erected on a main frame 11. As shown in FIG. 2, the main frame 11 includes a front frame 1 in which prismatic members are connected in a U-shape in plan view.
2 and a rear frame 13 are connected to the front upper part and the rear lower part of a pair of left and right vertical frames 14, 14 made of prismatic tubes, respectively, and the safety frame 10 has a lower end thereof. It is fitted into the vertical frames 14 and fixed to prevent it from coming off.

[0011] The bonnet cover 4 is attached to the rear frame 1.
The lower part of the rear end is pivotally attached to the rear horizontal frame member 13B of No. 3 so as to be vertically swingable around the horizontal axis, and the upper surface of the front and rear frame members 13A, 13A as a pair of left and right vehicle body frames in the rear frame 13. It is configured to be mounted directly. That is, as shown in FIG. 1, the left and right lower edges 4a, 4a of the bonnet cover 4 are formed to span across the left and right front and rear frame members 13A, 13A.
are configured as abutting edges that face and butt against the upper surfaces of the front and rear frame members 13A, 13A, and sealing materials 15, 15 are attached to the lower edges 4a, 4a, and the sealing materials 15 , 15, the bonnet cover 4 is mounted and closed with the lower edges 14a, 14a and the upper surfaces of the front and rear frame members 13A, 13A brought into close contact with each other. The locking mechanism 17 prevents the bonnet cover 4 in this closed position from opening.
is fixed. When performing maintenance on the engine 6, radiator 16, etc., the grass collection container 5 is moved from above the bonnet cover 4, and the unlocked bonnet cover 4 is swung open upward.

[0012]Although reference numerals are written in the claims for convenience of comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
