Description

[Detailed Description of the Invention] The present invention relates to a driver seat step support device for a working machine such as a tractor or a rice transplanter.

Generally, steps are provided on both sides of the driver's seat of working machines such as tractors or rice transplanters for the driver to place his or her feet on.In order to support these steps, support beams or the like are extended from the vehicle body frame. Ta. However, providing a special support member having a certain degree of strength to support the step in this way not only complicates the structure but also increases the weight of the working machine.

In view of the above, the object of the present invention is to provide a driver's seat step support device for a working machine that has an extremely simple structure and is capable of reinforcing and supporting the driver's seat step without increasing the weight of the vehicle body. .

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 4.

1 and 2, a transmission 1 is provided in the center of the vehicle body of the riding rice transplanter, and a front frame 2 extends forward from the transmission 1. On this front frame 2, an engine is mounted. 3 is installed.

A final case 4 extends laterally from the left and right center portions of the transmission 1, and a front wheel 5 is attached to the lower end of a vertical portion 4a of the final case 4. This final case 4 does not have a center pivot, is fixed to the mission 1, and does not move vertically or horizontally.

A pair of chain cases 6 extend diagonally downward and rearward from both left and right rear sides of the transmission 1, and a rear wheel 7 is attached to the rear end. A driver's seat 8 is formed above the transmission 1, and the driver's seat 8 includes a handle 9, a change lever 10, a seat 11, etc., and auxiliary seedling mounting frames 12 are attached to both left and right sides of the seat 11.

A rear frame 11 supporting the seat 11
A planting section 14 is vertically movably connected to a link mechanism 13 provided between the chain cases 6 and 6, and this planting section 14 is connected to a float 15, a planting rod 16, a seedling tank 17, etc. It is equipped with

Steps 18 are installed on both left and right sides of the driver's seat 8 in the longitudinal direction of the vehicle body.
Its inner end is fixed to the side of the mission 1, and its front end is folded upward.

As shown in FIG. 3, an inverted L-shaped plate-shaped support 19 is attached to the outer end of the upper end of the vertical portion 4a of the final case 4 with bolts 21. The front part of said step 18 is supported on top.

The chain case 6 is formed by combining two elongated plate-shaped halves 6a and 6b, as shown in FIG. 22, and this support 20 supports the rear part of the step 18.

In this way, by attaching the supports 19 and 20 on the final case 4 and the chain case 6 and supporting the front and rear parts of the step 18 as appropriate, a special member such as a support beam for supporting the step can be provided. Step 1
8 is definitely supported. In the above embodiment, the supports 19 and 20 were formed of plate-like bodies, but
Of course, this may be formed of other members such as a pipe member, an L-shaped member, or a channel member.

In this embodiment, the case of a riding-type rice transplanter has been described, but it goes without saying that the present invention can be similarly applied to other working machines such as tractors in which the final case is fixed.

As explained above, the present invention provides a working machine equipped with a fixed final case that supports the front wheels and a chain case that transmits driving force from the transmission to the rear wheels. Since the lower surface of the driver's seat step is reinforced and supported by this support, the step can be strongly supported and reinforced with a simple structure, reliably, and without increasing the weight of the working machine. play.
