Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a hood at the front of a fuselage and a working device (such as a seedling planting device or a direct sowing device) at a rear portion of the fuselage. The present invention relates to a configuration near a driving seat of a paddy field working vehicle (for example, a riding type rice transplanter, a riding type direct sowing machine, a riding type chemical sprayer, etc.) arranged.

[0002]

2. Description of the Related Art In a paddy field working vehicle such as a riding type rice transplanter,
It has been proposed to provide a roof for shade and rain above the driver's seat. In this case, the roof cannot be placed too high because of the stability of the aircraft in strong winds and the ability to store the paddy field work truck without hindrance even in a barn with a low ceiling. The configuration is such that the roof is arranged at a position slightly higher than the head of the worker sitting on the driver's seat.

[0003]

In a paddy field working vehicle in a paddy field, when changing workers or replenishing from a ridge (for example, replenishing spare seedlings, etc.), the airframe is moved to the ridge and the (For example, the body is applied to the ridge at a substantially right angle). This allows workers to take turns through the side of the hood at the front of the fuselage,
Supplies are supplied from the ridge through the side of the hood at the front of the aircraft.

[0004] In this case, for example, when the operator is changed or replenished from the ridge as described above, if the operator in the driver's seat stands up carelessly diagonally forward toward the side of the bonnet, the work is not performed. There is room for improvement, as workers must stand up with caution, such as raising their heads with their heads down so that they do not hit the roof, because there is a risk that workers will hit their roofs. SUMMARY OF THE INVENTION It is an object of the present invention to provide a paddy field working vehicle that can be easily replaced by a worker or supplied from a ridge.

[0005]

Means for Solving the Problems [I] When a roof is arranged above a driver's seat in a paddy field working vehicle, if the roof is formed to have a front tapered shape as in the characteristic of claim 1, the roof can be seen in plan view. The front right portion and the front left portion of the hood protrude toward the lateral side of the bonnet and do not enter a large state. With this, when the operator in the driver's seat stands diagonally forward toward the side of the bonnet, in order to change workers and supply from the ridge, even if the worker stands up without fully lowering his head There is no such thing as putting your head on the front right or front left of the roof. As described above, if the roof is formed to have a narrow front, the front right portion and the front left portion of the roof are less likely to be obstructed when the operator of the driver's seat looks obliquely upward.

In this case, with respect to the width of the front side of the roof,
Since the width of the roof in the upper part of the driver's seat is wide, the function as a sunshade and a rain shield above the driver's seat is sufficiently exhibited.

[II] According to the feature of the second aspect, similar to the case of the first aspect, the present invention has the "action" described in the above-mentioned [I], and additionally has the following "action". ing. When the collecting unit is provided as in the second aspect, rain falling on the upper surface of the roof can be collected at a predetermined position and dropped to a convenient position. It is possible to avoid a situation where rain falls on an inconvenient part (for example, a fertilizer tank in a riding rice transplanter with a fertilizer application device).

[III] According to the feature of the third aspect, similar to the case of the first or second aspect, the "action" described in the above-mentioned [I] or [II] is provided. It has various “actions”. According to the third aspect of the present invention, the operator of the driver's seat can visually check the support frame provided on the front part of the body (right and left side walls of the hood) separately from the instrument panel of the driver. Because it has a display unit, many display devices can not be provided on the instrument panel of the driving unit, or can be provided on the instrument panel of the driving unit but are located only in the part hidden by the steering wheel etc. A display device that cannot be provided can be provided in the display portion of the support frame.

In this case, when the operator in the driver's seat looks at the instrument panel of the driving unit, his head must be turned downward to some extent, while the display unit of the support frame is higher than the instrument panel of the driving unit. Position, so that the operator of the driver's seat can easily turn the display part of the support frame just by turning his head slightly to the right or left (diagonally lower right or diagonally lower left, diagonally upper right or diagonally upper left). Can be visually observed. Therefore, a display device that needs to be carefully observed so as not to be overlooked during the work (for example,
In a riding type rice transplanter, a seedling cutting lamp or the like that indicates that the number of seedlings on the seedling rest is reduced to a predetermined amount or less) and a display device whose display content is changed relatively frequently are displayed on the display portion of the support frame. With this arrangement, it is less likely that the operator of the driving unit will overlook the display on the display device.

According to the third aspect of the present invention, since the pair of left and right direction indicators are supported by the support frame of the roof, a dedicated support frame for the pair of left and right direction indicators is not required. The direction indicators can be arranged at a relatively high position (for example, near the roof) to make it easier to see the pair of left and right direction indicators from the other.

According to the third aspect of the present invention, since the support frame is erected along the right and left lateral walls of the bonnet, the support frame largely extends laterally outward from the range of the left and right width of the bonnet. Not a state. As a result, as described in the preceding section [I], when the operator is replaced or replenished from the ridge, the support frame is not obstructed, and the support frame is used as a handrail for the operator to hold. Can be used.

[IV] According to the characteristic of claim 4, as in the case of any one of claims 1, 2 and 3, any one of the above-mentioned [I] [II] [III] And the following "action" in addition to the above. When the display unit and the pair of left and right direction indicators are provided on the support frame as in the feature of claim 3, according to the feature of claim 4, the wires of the display unit and the pair of left and right direction indicators are inside the support frame. And is not exposed to the outside. Therefore, as described in the preceding section [I], when the operator switches or replenishes from the ridge, the operator touches the display unit and the wires of the pair of left and right direction indicators. There is no such thing as damaging this.
