Abstract

PURPOSE:To stop a roll baler at the releasing position in stable state preventing the rolling down of a roll bale by providing a trailer with a tiltable deck supporting a roll bale and making the roll bale releasable in either of right and left directions. CONSTITUTION:In the case of collecting dried grass on a hillside pasture, a roll bale A produced by a grass-harvester is placed on a deck 1a of a trailer 1 in a state directing the circumference in longitudinal direction. When the surface F of the hillside pasture is declined to the right side, a liftable frame 7 is tilted with a hydraulic cylinder 12 to release a roll bale A in a state directing the circular face downward and contacting the face with the surface of the field F. The roll bale A can be stably placed on the surface without causing the rolling down. When the surface F of the hillside pasture is declined to the left side, a liftable frame 6 is tilted with the hydraulic cylinder 11 to release the roll bale A in a state directing the circular face downward and contacting the face with the surface of the field F and stably place the roll bale A without causing the rolling down.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention mainly aims at controlling the release direction and release posture of roll bales (cylindrical packed grass) produced by a roll baler type grass (hay) harvester into the field. The present invention relates to a release position control device for a roll baler.

[Conventional technology]

Conventionally, roll baler type machines have been known as pasture harvesting machines, and in recent years they have come to be widely used for producing hay from pasture. This roll baler type grass harvester is used to dry cut grass on the ground in the field, pick up this hay, make it into a belt, wrap it into a cylindrical shape with a predetermined width, and when the diameter of the hay reaches approximately the predetermined size. A roll bale is manufactured by packing (binding) the outer periphery of the circumferential side with a string, and the roll bale is rotated and released backward in the direction of movement of the machine with the circumferential surface touching the field. No problems occurred when it was used on flat pastures.

[Problem to be solved by the invention]

However, when this harvester is used on a slope, the rolled bales that are produced and released will roll down the slope (toward the valley side) because the circumferential surface is in contact with the field and rotational force is applied. , which cannot be kept in the release position, which is not only dangerous, but also requires time and effort to collect, and may interfere with later harvesting operations.

There were such sighting points.

Therefore, in order to solve the above-mentioned problems, the present invention has been developed to attach a trailer to the rear of the roll baler and tow it.
Once the cylindrical roll bales produced by the roll baler are loaded onto a trailer, they are released either to the left or right with the circular side facing down depending on the terrain, and the roll bales are stably released without rolling down. An object of the present invention is to provide a release position control device for a roll baler that can be kept in position.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a trailer towed by a roll baler type hay harvesting machine and loaded with roll bales produced by the hay harvesting machine, with the deck of the trailer being set in a substantially horizontal state and a left-tilt state. The deck is characterized in that it can be displaced to a rightward tilted state, and the roll bale loaded on the deck can be discharged in either the left or right direction.

[For production]

With the above configuration, the trailer deck can increase its inclination angle in either the left or right direction with respect to the traveling direction, and the roll bale rotated and transferred from the roll baler onto the trailer deck can be rotated left or right depending on the terrain. The deck is tilted in either direction, and when the roll bale exceeds the angle of repose, it slides on the deck surface and is released with its circular flat surface in contact with the field. That is, the roll bale is discharged to the upper side of the slope (mountain side), and the circular flat part of the roll bale is always kept in contact with the field to prevent transfer, and the roll bale is left stably. Therefore, as with conventional roll bales, when the circumferential surface is in contact with the field and is released while rotating towards the rear of the machine, the roll bales are tilted downward (valley side).
This will prevent you from falling down.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In Figures 1 to 3, the reference numeral 1 is connected to the rear of a roll baler type grass harvester (not shown) and is towed, and a roll bale produced by the grass harvester is loaded and released into the field. This trailer l is equipped with a pair of left and right wheels 3 and 4 at the bottom of a body frame 2, and a traction rod 5 protruding forward from the front part of the body frame 2 is attached to a grass harvester. It is connected to the rear and can be towed.

Deck la for loading roll bales on trailer l
, a position where a pair of elevating frames 6 and 7 are combined with each other from the left and right sides and are in a substantially horizontal state together with the vehicle body frame 2, a rightward tilting state where the elevating frame 6 is tilted to the right, and a position where the elevating frame 6 and the elevating frame 6 are in a substantially horizontal state, and the elevating frame 7 is capable of being displaced to an inclined state in which it is inclined toward the left side. The elevating frame 6.7 is a deck support 9.7 supported by the vehicle body frame 2. It is rotatably supported by the IO and can be rotated left and right to move up and down. A stopper plate 8 is provided vertically upward at the rear end of the vehicle body frame 2 to prevent the roll bales from falling backward when loaded.

The base end portions of hydraulic cylinders 11.12 for individually raising and lowering the lifting frames 8.7 are pivotally mounted by a support shaft 13 provided at the center of the vehicle body frame 2 in the left-right direction. The tips of the 12 pistons are connected to a deck arm 18.17 via a cylinder pin 14.15. Further, the hydraulic cylinders 11 and 12 are provided with hydraulic pipes 18 and 19, which communicate with and are connected to a hydraulic control valve (not shown).
12 are controlled separately.

In the roll baler discharge position control device having such a configuration, when harvesting hay on a sloping pasture as shown in FIG. They are loaded with their circumferential surfaces facing forward and backward. If the inclination direction of the field scene F in the sloping pasture is downward to the right as shown in Fig. 4 (f), the hydraulic cylinder 1

Avoid transferring and keep it stable.

Also, the slope direction of the field scene F of the sloping pasture is shown in Figure 4)
If it is tilted downward to the left as shown, actuate the hydraulic cylinder 11 to tilt the lifting frame 6 and release the roll bale A with its circular surface facing down in contact with the field F to prevent it from being transferred. and let it stand stably.

In addition, normal hay production is harvested using contour line work.

Work such as reversing and packing is often performed, but even if work is performed up and down a slope along an incline, the stopper plate 8 provided at the rear end of the roll baler release device prevents the roll bale from falling backwards. prevent.

In the above embodiment, the frame deck is constructed as a fixed type, but it is also possible to use a turntable type so that the emission angle can be freely changed.

〔Effect of the invention〕

As explained above, according to the release position control device for a roll baler according to the present invention, the deck of the trailer can be moved between a horizontal state, a left tilted state and a right tilted state. can be stably released even on slopes. Therefore, it is possible to work safely even on sloping grasslands where conventional roll balers cannot be used.
