A front axle 121 and a rear axle 125 may be rotatably installed on the lower side of the vehicle body 110, respectively, and the front axle 121 and the rear axle 125 may have wheels. Wheels 121a and 125a to be installed may be installed respectively. As the front axle 121 and the rear axle 125 rotate, the agricultural vehicle according to the first embodiment of the present invention including the vehicle body 110 may be driven.

The rear axle case 130 may be installed at a portion of the vehicle body 110 where the rear axle 125 is installed, and the rear axle 125 may be rotatably supported and installed on the rear axle case 130. In this case, both ends of the rear axle 125 may protrude to the outside of the rear axle case 130 to be exposed.

An engine (not shown) that generates power may be mounted and installed on the front side of the vehicle body 110, and a driver's seat 140 for driving the agricultural vehicle according to the first embodiment of the present invention may be installed at the rear of the engine. I can.

In the small agricultural vehicle, because a separate cab is not formed due to space constraints, the driver's seat 140 is exposed to the outside. Then, the driver may be injured due to overturning of the agricultural vehicle. In order to prevent the driver from being injured due to overturning of the agricultural vehicle, a rollover protection system (ROPS) 150 is installed at the portion of the vehicle body 110 behind the driver's seat 140.

The protection frame 150 may be formed in an approximately "∩" shape, and the lower end may be supported and installed on the vehicle body 110, and the upper end may be positioned higher than the driver who boarded the driver's seat 140. Thus, the protection frame 150 can prevent the driver from colliding with the ground when the agricultural vehicle according to the first embodiment of the present invention is overturned.

Further, a front work machine 161 such as a loader or the like may be installed on the front outside of the vehicle body 110, and a rear work machine 165 such as a backhoe may be installed on the rear outside.

The front work machine 161 and the rear work machine 165 have a large weight, and a large load is required when working with the front work machine 161 and the rear work machine 165. Therefore, the front work machine 161 and the rear work machine 165 must be firmly coupled to the vehicle body 110 to perform stable work with the front work machine 161 and the rear work machine 165.

To reinforce the rigidity of the vehicle body 110 and to be able to firmly couple the front work machine 161 and the rear work machine 165 to the body 110 side, the vehicle body 110 has a mounting frame (Mounting Frame) ( 170) can be installed. More specifically, the mounting frame 170 may be installed on the rear axle case 130.

The mounting frames 170 may be provided in pairs, respectively installed on both side surfaces of the rear axle case 130, and may have a predetermined length along a front-rear direction that is a longitudinal direction of the vehicle body 110. The mounting frame 170 may be detachably coupled to the vehicle body 110.

The mounting frame 170 is a structure that reinforces and supports the rigidity of the vehicle body 110 and the coupling rigidity of the front working machine 161 and the rear working machine 165 to the vehicle body 110, and has a heavy weight and a large volume. For this reason, it may be inconvenient to work to install the mounting frame 170 on the vehicle body 110. In particular, when the mounting frame 170 is installed on the rear axle case 130, it may be very inconvenient because the mounting frame 170 must be installed so as not to interfere with the rear axle 125.

The agricultural vehicle according to the embodiment of the present invention may be formed by dividing the mounting frame 170 into two so as to be conveniently installed on the rear axle case 130. The mounting frame 170 will be described with reference to FIGS. 2 to 6.

Then, when the mounting frame 170 is installed on the vehicle body 110, the relatively lightweight first mounting frame 171 is first installed on the vehicle body 110, and the relatively lightweight second mounting frame 175 is installed on the vehicle body. Since it can be installed later on 110, the mounting frame 170 can be conveniently installed on the vehicle body 110.

The first mounting frame 171 and the second mounting frame 175 may be detachably coupled to each other. Accordingly, when the operator intends to use only the front working machine 161, the second mounting frame 175 can be separated from the vehicle body 110 and the first mounting frame 171. When the operator intends to use only the rear work machine 165, the first mounting frame 171 may be separated from the vehicle body 110 and the second mounting frame 175. As described above, the working vehicle according to the present invention is implemented so that any one frame can be relatively simply separated when the operator wants to use only one working machine in various working environments, so that the fuel economy of the vehicle increases as the overall weight increases.
