Description

[Detailed description of the device]

[0001]

[Industrial applications]

 TECHNICAL FIELD The present invention relates to a control structure of a work vehicle.

[0002]

[Prior Art]

 In the structure of the control part of the work vehicle, the instrument panel in the control part is conventionally attached and connected to the bonnet rear cover arranged on the rear side of the engine bonnet as shown in, for example, Japanese Utility Model Laid-Open No. Sho 62-120048. There was a composition.

[0003]

[Problems to be solved by the device]

 However, according to the above-mentioned conventional structure, since the bonnet rear cover is used as a strength member, it is necessary to construct it with high rigidity such as metal, which requires a large number of assembly steps and a large weight. There was a disadvantage in reducing the size and weight of the aircraft. The present invention aims to solve the above-mentioned problems.

[0004]

[Means for Solving the Problems]

 The characteristic structure of the present invention is that an instrument panel equipped with a control switch, an instrument, etc. is connected and supported by a stay standing upright from the main frame and a handle post, and the upper portion of the bonnet rear cover is connected to the instrument panel. There is a point.

[0005]

[Action]

 The instrument panel is firmly connected and supported by a strong stay that stands upright from the main frame and a handle post that is placed close to the instrument panel in the control section, and even if you connect the bonnet rear cover to this instrument panel. Therefore, the bonnet rear cover for covering the circumference of the instrument panel and the circumference of the handle post can be made of a light and easy-to-handle material such as synthetic resin.

[0006]

[Effect of the device]

 Therefore, it is possible to reduce the weight of the bonnet rear cover, which has a large area for covering the control section, and it is possible to reduce the weight of the machine body, and at the same time, it is easy to handle during the assembly work and the workability is improved. Can be excellent.

【Example】

 Embodiments will be described below with reference to the drawings. FIG. 5 shows a riding type rice transplanter. This rice transplanter is constructed by connecting a seedling planting device 2 to a rear portion of a riding type traveling body via a link mechanism 1 so as to be able to move up and down. In the traveling machine body, a driving part 4 is provided in a hood 3 at the front part of the machine body, a boarding control part 5 is provided behind the hood 3, and a spare seedling storage base 8 is provided at the rear part of the driver's seat 6.

As shown in FIG. 4, the rear spare seedling storage base 8 on the rear side of the driver's seat 6 is constructed by connecting a horizontal rod 11 over the upper portions of a pair of left and right columns 10 standing upright from the machine body frame 9, A pair of front and rear support rails 14 for slidably mounting and supporting eight seedling scooping plates 13 in a lateral direction via brackets 12 from both left and right sides of the horizontal rod 11 are fixedly connected to each other so as to project to the left and right outer sides. Configured. The preliminary seedling storage base 8 is configured so that the preliminary seedlings can be supplied from the ridge side through the lateral outer end of the support rail 14 during the planting operation. The left and right brackets 12 and 12 are configured to be rotatable and positionally fixed relative to the horizontal rod 11 about a horizontal axis, and the operation lever 15 is used to lower the preliminary seedling placement support posture and the rear side. It is configured to be switchable between a seedling supply posture to the seedling stand 16 which swings and tilts. When more seedling scooping plates 13 are to be placed, an extension support frame 17 is flange-connected to the lateral side of the horizontal rod 11 so that it can be accommodated.

Next, the structure of the control unit 5 will be described. As shown in FIGS. 1 to 3, a steering support base 18 is installed over a pair of left and right body frames 9, 9 and a steering post 18 is vertically fixed to the steering support base 18. Then, a horizontal frame 20 extending laterally along the rear edge of the steering support base 18 is fixedly connected, and the lower surface side of the driver section step 21 is bolted to the horizontal frame 20 via a mounting bracket 22. In addition, the inner surface of the lower side of the bonnet rear cover 23 is connected by bolts via a mounting bracket 24.

An instrument panel 25 including operating switches, instruments and the like is connected and supported by a stay 26 standing upright from the machine body frame 9 and a handle post 19, and the instrument panel 25 is provided with an upper portion of the bonnet rear cover 23. Are connected. More specifically, the two sides of the instrument panel 25 are connected and supported by the stays 26, 26 that are erected from the middle of the support rod 27 that is fixedly extended from the lateral side to the upper side of the left and right body frames 9, 9. The rear side of the instrument panel 25 is connected and supported by a bracket 28 that extends forward from a midway position of the handle post 19. Then, the bonnet rear cover 23 is attached from the upper side, and the periphery of the instrument panel 25 is fixed with screws. The engine bonnet 3 that covers the driving part 4 is swingably provided around the horizontal axis below the front part of the machine body, and on the rear side, both left and right side parts except the bonnet rear cover 23 swing integrally. Is done.

In the claims of the utility model, reference numerals are provided for easy comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
