Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a blow-up harvester device comprising a blow-up harvester (forage harvester) for harvesting crops such as maize or grass, and a crop storage device. Regarding.

(Prior art) As a conventional blow-up harvester device,
There are the one shown by the reference numeral 1' in the figure and the one disclosed in Japanese Patent Laid-Open No. 56-39713.

In the former technology, a harvester M is attached to the side of a traveling vehicle T, and a storage wagon W is towed at the rear, and a single device harvests maize (crop), stores and transports it, and improves work efficiency. We are planning to improve this.

In addition, the latter technology creates a loading platform at the rear of the vehicle and mounts a storage device on it, and a control section is installed on one side of the front in the width direction, so that the harvesting area of the harvester installed at the front is within the width of the vehicle. configured to be located.

(Problems to be Solved by the Invention) In the former technology, since the wagon W is a towed type, the overall length of the device is very long, the turning radius at the corner of the field is large, and the wagon W is of a tow type. Earth A
had to be increased as shown by the solid line in Figure 1.

Also, when turning, the position of the wagon W relative to the vehicle T and the maize harvester M changes left and right, so the angle of the chute of the harvester M must be adjusted left and right in accordance with the movement of the wagon W.
It required complicated operations.

Furthermore, since the harvester M is attached to the side of the vehicle T, before putting the device into the field, the maize must be harvested in advance by a width corresponding to the rear wheel width of the vehicle T on its outer periphery, and the pre-harvesting section B had to be formed in advance, and much of the work was done manually.

These problems can be solved to some extent by creating a loading platform at the rear of the vehicle and keeping the reaping area within the width of the vehicle, as in the latter technique. However, with the latter technology, in order to create a loading platform, a control unit and an engine must be installed on the left and right sides of the front of the vehicle, and the control unit is biased to one side, resulting in poor visibility on one side of the harvester. , and it is difficult to reuse existing vehicles such as tractors, and the reaping area overlaps with the vehicle in the width direction, but both sides of the reaping area are located well inside from both sides of the vehicle. Vehicles are forced to trample the maize outside the harvesting area, creating new problems.

(Means for Solving the Problems) The present invention provides a blow-up type harvester M at the front of a traveling vehicle T having a control section 13 approximately in the center in the vehicle width direction.
The crop storage device 2 is installed on the rear bonnet 11.
By arranging one side of the reaping area E of the harvester M to substantially coincide with one side of the vehicle, all of the problems of the prior art described above can be solved.

That is, the specific configuration of the problem-solving means of the present invention is characterized in that a control section 13 is provided approximately in the center of the vehicle T in the vehicle width direction, and a blow-up harvester M is mounted in front of the control section 13. , in a blow-up harvester device in which the harvest storage device 2 is arranged behind the control section 13, one side of the reaping area E of the blow-up harvester M is one side of the vehicle T that overlaps the reaping area E in the width direction. The crop storage device 2 is arranged on the bonnet 11 that covers the engine 3 of the vehicle T.

(Function) Harvester M performs harvesting work in front of vehicle T. The reaping area E overlaps with the vehicle T in the width direction, and one side of the reaping area E substantially coincides with one side of the vehicle T, so the vehicle T steps on uncut crops outside the reaping area E. I never wear it. In addition, the harvest storage device 2 is placed on the bonnet 11 without having to create a special space to form a loading platform, thereby reducing the longitudinal length of the vehicle.
