Description

[Detailed Description of the Invention] Industrial Field of Application The present invention has a field of application for a fender mounting device for an agricultural tractor.

Prior Art As shown in Japanese Utility Model Publication No. 58-19946, the front part of the fender was attached to the rear part of the step with bolts.

Problems to be Solved by the Invention In the above conventional technique, the fender is attached to the rear end of the step with a bolt, so the loosening of the bolt causes the fender to vibrate and generate noise, and the step support strength is insufficient. There was a problem.

Means for Solving the Problems This invention has taken the following technical means in order to solve the above problems. That is, a mounting frame configured by connecting the left and right inner and outer walls to the ceiling is attached to the side portions of the left and right side strength members of the floor laid in the driver's seat of the vehicle body, and the safety frame is attached to the corner of the mounting frame. The front mounting portion was erected, and the crown-shaped mounting portion extending to the front side of the fender in which the rear portion was mounted on the strength member was crowned to the mounting frame.

The present invention is to install a mounting frame configured by connecting the left and right inner and outer walls at the ceiling to the front side of the left and right side strength members of the floor laid on the driver's seat of the vehicle body, and to attach the corners of the mounting frame. Since the front mounting part of the safety frame is erected on the above, and the coronal mounting part extending to the front side of the fender with the rear part attached to the strength member is crowned to the above mounting frame, the fender and the safety frame can be firmly mounted, and Can be widely configured.

Embodiment One embodiment of the present invention will be described below with reference to the drawings.

First, the configuration will be described. Agricultural tractor body 1
In the upper part from the clutch housing 2 to the hydraulic case 3, side strength members 5 and 5 having a substantially rectangular cross section and stepped portions 4 and 4 formed at outer corners and rearwardly raised like a crank are attached. A floor 7 is formed by attaching a floor plate 6 formed in a crank shape so that the rear central part is bulged to the side strength members 5 and 5 so that the rear central part is raised.

Attached to the front side of the side strength members 5, 5 are mounting frames 11, 11 which are formed by bending a sheet metal so as to form left and right inner side walls 9 and outer side walls 10 of the ceiling part 8 by bolting. Frame 11,
Square pipe-shaped mounting portions 12, 12 are welded to the front outer corner of 11 so as to project upward.

Then, in the mounting frames 11 and 11, the coronal mounting portions 17 and 17 are formed by bending with a sheet metal so that the inner wall 15 and the outer wall 16 are opposed to the left and right of the upper wall 14 at the lower front part of the fenders 13 and 13. The outer walls 16 and 16 are put on the mounting frames 11 and 11, and the outer walls 16 and 16 are bolted to the outer walls 10 and 10 of the mounting frames 11 and 11, and the inner side walls 9 and 9 are on the side of the stepped portions 4 and 4 of the side reinforcing members 5 and 5. Install it by tightening the bolts. And fender 13,1
The rear side of 3 is bolted along the side reinforcing members 5, 5. In addition, 18 is a safety frame, 19 is a front column of the safety frame 18, and 20,21,22,23 are bolt holes of the tightening bolts 24,25,26.

Next, the function and effect will be described. In the above embodiment, the fenders 13, 1 are attached to the mounting frames 11, 11 mounted on the front side of the left and right side strength members 5, 5 of the floor 7 provided on the upper part of the vehicle body 1.
Since the coronal mounting parts 17, 17 provided on the lower front part of 3 are attached and bolted, the rear parts of the fenders 13, 13 are also bolted along the side reinforcing members 5, 5. The fenders 13 and 13 are firmly attached and the above-mentioned mounting frame 1
Front stanchions 19,19 of safety frame 18 to 1,12 square pipes 12,12
By fitting and mounting the safety frame 18, the mounting portion of the safety frame 18 can be lowered and the mounting and dismounting can be facilitated.
