DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates mainly to the harvesting of beans (all beans such as red beans, soybeans, kintoki, handshake, dainagon, etc.), but can also be partially used for harvesting buckwheat. After cutting and drying the crops (beans), the crops can be picked up and threshed by a threshing device having a pickup device such as a known general-purpose combiner.

[0002]

2. Description of the Related Art Heretofore, this type is as follows. Conventional bean harvesting operations are mostly self-propelled, walking and riding single or double bean harvesters, with a disk-shaped or bush-shaped (hair clipper) cutting blade in front of the machine. This is a method in which the crop is harvested, moved backward by a conveyor belt, chain, etc., dropped into a bucket installed at the rear, and dropped to the ground when a certain amount of water is collected. The main procedure was drying and threshing.

[0003]

The above-mentioned prior art has the following problems. 1. When the crop dries, the pods are easy to fly when mowing, and the mowing work cannot be performed unless it is moist, so it is necessary to work early in the morning or at night, and also cannot work on windy days. 2. After harvesting, it is necessary to pile up nios and make strips, which requires a lot of manpower and moves the crops. 3. The threshing operation is performed again after the drying, so that even in this case, the crop is again popped by the movement of the crop. 4. As for the above-mentioned several operations, labor is required each time, so that the cost becomes high, and moreover, popping-up state often occurs. In addition, the limited time when they can work has adverse effects on other field work. The present invention has been made in view of such problems of the conventional technology, and has as its object to provide the following.
This is a trimming device to be mounted on small to medium tractors with raised floors. A reaper is equipped with a reaper using two or four rotating blades and a divider at the front of the tractor, and the rotation of the reaping blade can be easily changed by hydraulic pressure or the like. Moreover, it is a device that allows the harvesting operation to be performed in such a manner that the crops are arranged so as to lie down in the furrows, or the crops are arranged so as to support each other every two rows. Then, after drying for half a day, the crop is picked up and threshed by a threshing device having a known pickup mechanism.
