Description

[Detailed description of the invention] The present invention relates to the structure of a tractor equipped with a safety frame and wheel fenders, and more specifically, to a mounting structure for a safety frame installed at the rear of the driver's seat. The object of the present invention is to increase the mounting strength of the fender and the safety frame.

The tractor safety frame mounting structure of this invention is.

It consists of a pair of left and right vertical rod members that are erected and fixed to the traveling body on the inner side of the body body than the rear wheel fender, and a horizontal rod member that connects the upper ends of the vertical rod members, and The rod member includes a fender support part that penetrates the upper part of each of the rear wheel fenders from the inside to the outside of the fuselage, and a fender support part that penetrates the upper part of the rear wheel fender from the fender support part to the upper part of the rear wheel fender. and a protruding safety frame mounting portion, and this configuration provides the following effects.

(2) Since the upper portions of the left and right fenders are connected to each other via a reinforcing frame consisting of a vertical rod member and a horizontal rod member attached to the fuselage, it is possible to prevent the fenders from swinging laterally due to vibrations of the fuselage or the like.

@ And, instead of attaching the safety frame directly to the fender, the fender is attached to a reinforcing frame consisting of vertical and horizontal rod members that increases the strength. It can be raised using a reinforcing frame.

■Furthermore, the safety frame is not attached to the horizontal rod member located inward of the fuselage than the inner vertical wall portion of the fender, but is attached to the fender support part located within the width of the fender. The relative distance between the seat and the safety frame is widened, which has the advantage of preventing the driver's elbows and arms from accidentally hitting the safety frame when the driver looks back to work.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.

The rear part of the tractor has a mounting part for attaching work attachments such as tilling equipment and plowing equipment, as well as a power output shaft 1 for transmitting driving force to these attachments. Gate-shaped frames 3, 3 are fixed to the traveling body (machine frame) 4 at the front and rear of the vehicle 2, and the shoulders of these frames 3, 3 are connected by strength members 5, 5 to protect the driver. This constitutes a safety frame 6.

The rear gate-shaped frame 3 of the safety frame 6 is
It is attached by the structure shown in FIGS. 2 and 3.

Vertical rod members 12, 12 are fixedly provided on both left and right sides of the transmission case 9, which is a traveling aircraft, and the upper ends of these vertical rod members 12, 12 are connected to each other via a horizontal rod member 13, and, The end of the horizontal rod member 13 passes through the upper part of the inner vertical wall portion 7a of the rear wheel fender 7 and is fixed to the outer hanging piece 7c.

With this configuration, the left and right rear wheel fenders 7, 7
The upper part of the frame is reinforced and connected via a reinforcing frame 11 consisting of the vertical rod members 12, 12 and the horizontal rod members 13.

Then, at the fender support portion 13a portion of the horizontal rod member 13 that penetrates the inner vertical wall portion 7a of the rear wheel fender 7,
A vertical tube 13b, which is a frame mounting portion into which the lower end of the rear gate-shaped frame 3 is fitted and fixed, is provided so as to penetrate through the upper surface portion 7b of the fender 7.

In this way, by attaching the lower end of the rear portal frame 3 to the fender support portion 13a located within the width of the fender 7, the width of the portal frame 3 is widened and the operator space is made as large as possible. It is.

In addition, 8 is an axle protruding from the transmission case 9,
A rear wheel 10 is attached to this axle 8.
