Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention includes a collecting stand for collecting the tied grass in a sideways position at the rear of a binding device for tying cut grass in a sideways position and discharging the same to the rear. Regarding the structure of the collection section of the strawberry harvester.

[Conventional technology]

Previously, the above-mentioned collection department Kozo had published Japanese Patent Application Laid-Open No. 2-10990.
As disclosed in No. 9, it is known that the recovery platform is configured to be switchable between a state in which it is dumped at a rear fulcrum and a state in which it is raised and lowered in parallel.

[Problem to be solved by the invention]

The conventional collection department Kozo mentioned above is designed to be convenient for practical use, as it can dump bundles of collected rush to the rear of the aircraft, or lift them parallel to the height of the truck bed. However, in order to take it home from the field and dye it with mud, it was necessary to transfer it to a container, which required a great deal of effort to handle the long and heavy bundles of straw.

The present invention has been made in view of the above circumstances, and provides a collection section structure that allows harvesting to be carried out in the same manner as conventional methods, while allowing for easy handling after harvesting.

[Means to solve the problem]

The characteristic configuration of the present invention to achieve the above object is to provide a rice grass harvester that is equipped with a collecting stand for collecting tied grass in a horizontal position at the rear of a binding device that binds cut rice grass in a horizontal position and discharges the same to the rear. In the partial structure, the collection table includes:
A connecting device is provided to removably connect a left and right open container having a bottom frame and front and rear side frames, and the front side frame of the container is configured to be vertically expandable and retractable. The action and effect are as follows.

[For production]

According to the above configuration, during harvesting work, the container is connected and fixed on the collection stand, and the front side frame is shortened and set low. As a result, when the rush that has been tied in a sideways position in the binding device is carried into the container, it can easily get over the front side frame without having to lift it too much.

In addition, when transporting the harvested grass, the front side frame is extended upward to prevent the piled grass from collapsing, the connection with the collection platform is released, and the container is moved onto the collection platform using a forklift or crane. It can be transported all at once in a short period of time.

The container-loaded straw grass that has been carried out in this way is sent to the mud dyeing processing department, where the entire container can undergo mud dyeing.

Furthermore, the harvester itself that has unloaded the container can immediately load and connect another container and move on to the next harvest, and the time lost for transporting the collected straw grass is shortened.

〔Effect of the invention〕

As described above, according to the present invention, by simply arranging and stacking containers in containers at the time of harvesting, subsequent transport to the outside of the machine,
It is now possible to efficiently load containers onto transport vehicles, transport them, or transport them to mud dyeing equipment on a container-by-container basis.

Also, in order to avoid having to transfer the rushes over and over again,
There is less chance of damaging the rush, and it is also effective in maintaining quality.

The plant side part of the rush that was forcibly conveyed and guided in front of the air outlet (6a) of the blower device (6A) is
) is installed, and a wind-type selection device (6) is installed that selects the interlayers blown upward by the air discharged from the grass. ) A locking claw-type lifting and conveying device (12) that guides the grass upward is provided, and a binding device (7) is provided to bind the rush that is placed and supported in a horizontal position on the deck (10). (20) to constitute a reaping section (A), this reaping section (A) is pivotally supported to be vertically swingable around the horizontal axis (X) with respect to the traveling machine body (4), and the above-mentioned The binding device (7) is moved up and down by a hydraulic cylinder (14) and a pantograph-type lifting link mechanism (22) at the rear of the binding device (7), and a pantograph-type lifting link mechanism (35) is installed at the rear fulcrum (Y).
) and which swings up and down (dump operation) (15)
An engine (16) and a driving section (9) are provided on the side of the collection stand (15), and these are mounted on a traveling body (4) equipped with left and right crawler traveling devices (11), (11). A riding-type strawberry harvester is constructed.

The weeding device (1) is supported in an upwardly tilted position and rotates a rod (la) having an oval cross-section at high speed to untangle the grass.

The clamping and conveying device (5) is composed of a pair of horizontally rotating left and right clamping belts (5a), which serve as a conveying section and span between a driving pulley and a driven pulley.
The belts (5a) and (5a) made of soft material hold the straw grass to the extent that it will not be damaged, and it is installed in a slightly upward tilted position. The front end of this clamping and conveying device (5) is located at the same position on both the left and right clamping belts (5a), (5a), and is located in front of the reaping device (3). ) surrounds the tip of the rush grass stem.

In addition, the right hand holding belt (5a) located on the binding device (7) side
) is positioned ahead of the binding area for conveyance, and the terminal end of the left clamping belt (5a) extends to a position beyond the binding area. Therefore, the stem end after bundling can be transported until it is released to the collecting table (15), and the stem end part that is released by the bundling device (7) will not be delayed.

As shown in FIG. 7, the lateral feed locking and conveying device (8) is located above the upper lateral feed locking and conveying device (8A) located above the picking device (6) and the reaping device (3). For the upper lateral feed locking and conveying device (8A), which consists of a lower lateral feed locking and conveying device (8B) located at The lower lateral feed locking conveyance device (8B) has its conveyance terminal located further forward and laterally from the air outlet (6a). Therefore, before the mown grass is subjected to the action of the sorting device (6), it can be conveyed to the side of the traveling machine (4) by the lower lateral feed locking conveyance device (8B), so that during the conveyance, the blower ( 6A
) has the function of separating short layers that are not affected by the wind discharge from the

The said selection device (6) is the said upper lateral feed locking conveyance device (8).
A) A blower device (6) provided with an outlet (6a) at the terminal position.
