Description

Agricultural work vehicle{AGRICULTURAL WORKING VEHICLE}

The present invention relates to an agricultural work vehicle with improved seat rotation prevention structure.

Agricultural machinery is a machine that performs agriculture, and is roughly divided into a machine directly involved in producing crops and a machine involved in processing the produced crops.

Agricultural machinery directly involved in the production of crops includes a tractor that performs work with traction by connecting various working machines, and a combine that mows the stems of crops while driving through farmland, then threshing and sorting. There is an agricultural work vehicle.

Various work machines are selectively connected to the front and rear sides of the tractor. Thus, when the work machine is connected to the front side of the tractor, the operator including the driver sits on the seat and performs the work, and when the work machine is connected to the rear side, the worker sits on a rear work sheet provided separately from the seat and works.

However, in the compact tractor, due to space limitations, it is difficult to separately install a seat and a rear work seat. For this reason, if you want to work by connecting the work machine to the rear side of the tractor, rotate the seat to face the rear side of the tractor, and then use it. That is, the sheet is shared with the rear work sheet.

To be able to use the seat as a rear working seat, the seat must be rotated. For this reason, a support unit for supporting the seat is installed in the tractor, and an upper portion of the support unit is installed to be elevating and rotatable. Then, the sheet is mounted and supported on the upper portion of the support unit.

When the seat faces forward or backward, the upper part of the support unit must not rotate, so that the operator can work stably.

A tractor, which is a conventional agricultural work vehicle, is provided with a complex structure with a rotation preventing module that prevents the upper portion of the support unit from rotating. Due to this, there is a disadvantage that the cost increases.

The present invention may be to provide an agricultural work vehicle capable of solving all the problems of the prior art as described above.

As shown, the agricultural work vehicle according to an embodiment of the present invention may include a chassis 110, and a wheel 120 connected to the axle is rotatably installed on the lower surface of the chassis 110 Can be. It is natural that the tractor runs as the wheel 120 rotates.

Hereinafter, in referring to the directions and surfaces of the constituent elements including the chassis 110, the direction in which the tractor advances is referred to as "front and front", and the direction in which the tractor moves backward is referred to as "rear and rear".

A seat 130 may be installed on the upper surface of the vehicle body 110 for a worker, including a driver, to sit. The seat 130 may be installed on the rotating member 240, which is an upper portion of the support unit 200, which will be described later, installed on the chassis 110.

A protective structure 140 such as a rollover protection system (ROPS) may be installed on the rear side of the seat 130 to prevent an operator from being injured by a rollover of the tractor.

A work machine 181 such as a loader or the like may be installed on the front side of the chassis 110, and a work machine 185 such as a back-hoe may be installed on the rear side. The working machines 181 and 185 may work by receiving power from an engine installed on one side of the chassis 110.

In the normal case, the seat 130 faces forward. Therefore, when the operator wants to work with the work machine 181 installed on the front side of the chassis 110, the operator can sit on the seat 130 and do the work. However, when the worker wants to work with the work machine 185 installed on the rear side of the chassis 110, it is difficult for the worker to sit on the front-facing sheet 130 and perform the work.

When the tractor is small, it is difficult to additionally install a sheet for the work machine 185 installed on the rear side of the chassis 110 due to space constraints. Accordingly, the seat 130 installed on the support unit 200 is configured to be rotated 180°, and the seat 130 is used for the front side work machine 181 and the rear side work machine 185. That is, the sheet 130 is commonly used.

However, since many parts are installed around the seat 130, when the seat 130 is rotated, the seat 130 may collide with the parts. To prevent this, the seat 130 is installed to be elevating, and the seat 130 is raised, rotated, and then lowered.

The seat 130 is installed on the upper portion of the support unit 200, and the upper portion of the support unit 200 is installed to be elevating and rotatable. Due to this, the seat 130 is lifted and rotated.

A support unit 200 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG. 4 is a perspective view of the support unit shown in FIG. 2, and FIG. 5 is a perspective view of the support member of the support unit shown in FIG. 4 viewed from a different direction.

As shown, the support unit 200 includes a support member 210, an elevating member 220, a support member 230, a rotating member 240, and a pressing unit 250 (shown in FIGS. 7 and 11). Can include.
