Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a harvesting work vehicle that travels in a narrow space and transports a harvested crop.
[0002]
[Prior art]
Conventionally, crop harvesting work has been performed by an operator moving between the furrows while pushing the harvesting platform. For this reason, when harvesting crops that grow in low positions such as straw or asparagus, it has become a burden on the workers, which has been a heavy burden on the workers.
Therefore, as in the technique described in JP-A-9-117205, a seat is arranged on one side of a traveling vehicle and a loading platform is arranged on the other side, so that crops in a low position can be easily harvested while sitting on the seat. Work vehicles that can be considered.
[0003]
[Problems to be solved by the invention]
However, when the harvesting operation is performed while sitting on a seat as in the above-described prior art, there is a problem that it is difficult to harvest a tall crop.
In addition, a problem arises in that the harvesting space for the seat is reduced by the seating space.
Therefore, in the present invention, it is possible to perform the maneuvering operation in both the sitting posture and the walking posture, and in particular, the space on the seat and the foot placement step which are not used at the time of walking maneuvering is effectively used as a load space for the harvest. It is an object to provide a harvesting work vehicle that can be used.
[0004]
[Means for Solving the Problems]
The loading platform 1 at the front of the vehicle body and the seat 2 at the rear are arranged at substantially the same height, and the middle lower part is connected by a flat footing step 3 to form a traveling vehicle having a concave shape in side view. The steering handle 4 is erected so that the steering operation can be performed in two postures by riding and walking, and at the front of the vehicle body, a loading platform for passing the plate-like body 5 between the loading platform 1 and the seat 2 A harvesting work vehicle characterized by providing an expansion means.
[0005]
[Action and effect of the invention]
Since the harvesting work vehicle of the present invention includes both the riding seat 2 and the walking steering handle 4 and enables the steering operation in two postures of riding and walking, the operator can The steering posture can be appropriately selected according to the height of the crop to be harvested, and the harvesting operation can be easily performed without burden. That is, the crop in the lower position is harvested while seated on the seat 2, and the crop with a high height is harvested while walking the vehicle from behind. In addition, when the operator performs the steering operation in the walking posture behind the vehicle as described above, the plate-like body 5 is extended between the loading platform 1 and the seat 2 to expand the space for loading the harvested items. The space on the foot placement step 3 in the state can be used effectively.
[0006]
【Example】
Next, embodiments of the present invention will be described with reference to the drawings.
The harvesting work vehicle of the present embodiment has a flat footing step 3 between the front frame 8 that supports the pair of left and right front wheels 7 and 7 and the rear frame 10 that supports the pair of left and right rear wheels 9 and 9. By connecting, it is formed in a traveling vehicle having a concave shape when viewed from the side.
At the rear end of the rear frame 10, a front-view gate-type control handle 4 is erected, and a key switch 11, a forward / reverse switch 12, By mounting an operation box 14 having an operation device such as a speed change switch 13, a steering operation from the rear of the vehicle is enabled.
[0007]
Reference numeral 2 denotes a passenger seat mounted on the upper surface of the rear frame 10.
The front frame 8 is equipped with electric devices such as batteries 15 and 15, a motor 16 and a control box (not shown), and the vehicle is pulled by a pair of left and right front wheels 7 and 7 driven by the electric device. And run.
On the upper surface of the front frame 8, a loading platform 1 for loading the harvest is mounted at the same height as the seat 2, and on the loading platform 1, a pivot fulcrum 6 at the rear end of the loading platform 1 is centered. A rotatable plate-like body 5 is mounted.
As shown in FIG. 1 (b), the plate-like body 5 is stretched over the rear seat 2 by the rearward rotation, so that the harvested product loading space can be expanded.
[0008]
Reference numeral 18 denotes an inclined stay attached to the front end of the loading platform 1 so as to be freely rotatable. By rotating the stay 18 upright, the plate-like body 5 is inclined and fixed at a predetermined angle as shown in FIG.
Reference numeral 20 denotes a storage hook for fixing the inclined stay 18 to a stored state.
A seesaw-type forward / backward pedal 19 that can swing back and forth about the vertical axis 17 is attached to the lower part of the back of the front frame 8, that is, the front end portion of the footrest step 3. The steering operation in the state is enabled.
In order to perform crop harvesting using the harvesting work vehicle having the above-described configuration, in the case of a crop in which the crop is grown at a low position, the worker sits on the seat 2 and sits on the seat 2 to toe the forward / backward forward pedal 19. Harvest work while operating with.
At this time, the operator seated at the rear of the loading platform 1 by tilting the front plate-like body 5 forward and upward by the inclined stay 18 and tilting the harvesting basket X installed on the plate-like body 5 backward. The inside of the harvesting basket X is easy to see and the harvested product is easily put in and out of the basket X.
[0009]
The seesaw-type forward / backward pedal 19 is erected so as to be able to swing back and forth along the back surface of the front frame 8, so that it does not interfere with the foot space and there is no erroneous operation such as stepping in accidentally. .
When harvesting a tall crop, the worker performs a harvesting operation while walking the steering handle 4 at the rear end of the vehicle body from behind the vehicle.
At this time, the front plate-like body 5 is pivoted backward and passed between the loading platform 1 and the seat 2, thereby expanding the harvesting space as shown in FIG. 1 (b), and the unused seat 2. In addition, the space on the foot placement step 5 can be used effectively.
[0010]
FIG. 5 is a side view showing another embodiment of the harvesting work vehicle of the present invention. By mounting the plate-like body 5 housed inside the loading platform 1 in a pull-out manner, the load space for the harvest can be expanded. It is composed.
It should be noted that although numbers are given in the claims section for convenience in comparison with the drawings, the present invention is not limited to the configuration of the attached drawings by this entry.
