Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention includes a collecting table that lays back a bundle of straw grasses in a posture where the harvested straw grasses are folded sideways and collects the strawberries in a posture that the harvested straw grasses are bundled in a posture of lying sideways and discharged backward. Concerning the structure of the recovery section of the Taobu Harvester.

[Conventional technology]

Conventionally, as the above-mentioned recovery part structure, as disclosed in Japanese Patent Laid-Open No. 2-109909, it is known whether the recovery table can be switched between a state of dumping at the rear fulcrum and a state of moving up and down in parallel. Has been.

[Problems to be Solved by the Invention]

The above-mentioned conventional collecting part structure is designed so that the collected bundle of strawberries can be dumped and discharged to the rear of the fuselage, or can be lifted in parallel and lifted up to the height of the truck bed so that it can be used practically conveniently. However, in order to take it back from the field and perform mud dyeing treatment, it was necessary to once reload it in a container, and it took a lot of labor to handle a long and heavy bundle of strawberries.

The present invention has been made in view of such circumstances, and provides a recovery part structure that can be easily handled after harvesting while performing harvest harvesting in the same manner as in the past.

[Means for solving the problem]

The characteristic configuration of the present invention for achieving the above-mentioned object is that of a straw harvester equipped with a collection stand for collecting the straw bundles in a backward posture by binding the cut strawberries in a horizontal posture and discharging the bundle to the rear. In the recovery part structure, a connection device for removably connecting a container for mounting straws to the recovery table is provided, and the container is provided with a bottom frame and front and rear side frames, and left and right are opened, and a front part is provided. The side frame has a structure in which it can be expanded and contracted up and down, and its action and effect are as follows.

[Work]

According to the above configuration, the container is connected and fixed on the recovery table during the harvesting work, and the front side frame is set to be short and low. This makes it possible to easily get over the front side frame without having to lift the strawberries bundled in a sideways posture in the binding device into the container very much.

On the other hand, when carrying out the harvested strawberries, the side frames of the front part are extended upward so that the piled strawberries do not collapse,
You can disconnect the container from the collection table and use a forklift or a crane to carry out the containers all at once from the collection table.

The container piled strawberries thus carried out are sent to the mud dyeing processing section, and the mud dyeing processing can be performed on the container as a whole.

In addition, the harvester itself that has dropped the container can immediately mount another container and connect it to the next harvest, and the loss time for carrying out the collected strawberries will be short.

In addition, as the container is open on both sides, even if the strawberries are long, the root and the tip of the plant only protrude from the container to the left and right, and the container is placed sideways from the binding device into the container. While adopting it, it is possible to collect strawberries of various lengths.

〔The invention's effect〕

As described above, according to the present invention, by simply aligning and stacking them once in a container at the time of harvesting, it is possible to carry them out of the machine, to be loaded on a carrier, to be transported, or to be carried into a mud dyeing device. You can now do it efficiently in container units.

In addition, since the transfer of the strawberries is not repeated many times, the chances of damaging the strawberries are reduced and the quality is effectively maintained.

Moreover, it can be used for collecting strawberries of various lengths without causing damage such as breaking the strawberries, and can be highly versatile.
