Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a roll baler that is capable of collecting and packing grass in one unit.

[Conventional technology]

Conventionally, the rake (C) was removed from the tractor (6) after collecting grass (windrow) to a width of 6 to 0.7 m (see Figure 7) using the rake (2). , the same tractor (6) has a chamber width of about 1.2moo.
- The roll baler was connected to perform packing work using the roll baler (see Figure 8).

[Problem to be solved by the invention]

As mentioned above, the grass collection work and packing work were done separately, so the correlation between the windrow width and the roll baler (23) chamber width was not considered important. It was narrower.

Therefore, in order to obtain the leakage of the package by the roll tray 2 (231), as shown in FIG. 8, the left side run and the right side run were alternately carried out at a fixed time difference.

When running this left and right alternately, a difficult driving technique is required to alternately align the end of the pick-up port of the chamber of the roll baler with the left and right edges of the windrow αQ. As shown in FIG. 1θ or FIG. 11, the roll-formed package Q9■ had become cone-shaped or barrel-shaped.

Cone-shaped or barrel-shaped roll-formed packages (hereinafter referred to as irregularly shaped packages) may cause the load to collapse or the binding twine (binding string) at the end of the roll to come loose or fall off during transportation. easy. If the load becomes separated due to the load becoming loose, the threads coming loose, or falling off, it is difficult to repair it, and it is not only undesirable to have a large loss of time and labor. There are deficiencies such as not being easy.

Furthermore, as a recent technology, a sealing technique in which a machine called a bale wrapper is used to wrap a film around the silage formed by a roll baler has become widespread. When working with this bale wrapper, the film is wrapped while rotating with the circumferential surface of the roll in contact with the roll, but in the case of a cone-shaped irregular package, it will be skewed, and the film will be wrapped in a barrel-shaped irregular package. In the case of a shaped package, it lacks stability and swings left and right, which is a problem.

In addition, if the width of the windrow and the width of the chamber of the roll baler are made equal, and when the packing work is performed after the grass collection work, the both ends of the chamber are aligned with the left and right edges of the windrow. It is conceivable that the above-mentioned problems can be solved, but the idea of making the windrow width and chamber width equal is because the above-mentioned matching operation is extremely difficult and almost impossible, especially at curved areas, and because they do not match. There is a fatal flaw in that there is always a portion left unused, so it cannot be adopted.

The present invention is a device that enables a human worker to perform grass collection work and packing work in one run, and a device that enables a worker to easily and reliably obtain a cylindrical roll-formed package. The purpose of the present invention is to provide a new roll baler with a rake, which is designed with the following features.

[Means to solve the problem]

In order to achieve the above object, the roll baler with a rake of the present invention includes a roll baler body of the type driven by the power shaft, which is equipped with a traction rod pulled by a tractor and a power shaft connected to the power take-off of the tractor, and a roll baler main body of the type driven by the power shaft, It has a pair of left and right rotary rakes provided on both sides of the intermediate portion, and a device for transmitting rotational force in the winding direction from the power shaft to the rotary rake at the intermediate portion of the power shaft, and in front of the pickup. This type has grass collection chutes installed on both sides of the position, and has a grass dividing plate installed at a position behind the two rotary rakes and in front of the rear end of the grass collection chute.

〔Example〕

The first embodiment shown in FIGS. 1 to 4 includes a two-split release type bale chamber (2) with a tire (1) installed on the lower surface with the load center placed, and A large number of forming rollers with protrusions (3) and a pick-up opening (
4), a compressor (not shown) that can be adjusted according to the processing amount, and a feeder rake (not shown) that forcibly transports the processed material picked up by the pickup into the bale chamber (2). ), an automatic twine device (not shown) that performs the bobbin winding operation, a traction rod (7) connected to the tractor (6), and a tractor (
connection shaft (8) to the power take-off Cl0) of
) etc. constitutes a roll baler main body (9), and
The interval can be adjusted on both left and right sides of the middle part of the traction rod (7) in the roll baler main body (9), and the connection shaft (8
) is provided with a pair of left and right rotary rake circles aυ', and a connecting shaft (8
) is provided with a rotational force transmission device α to receive the rotational force in the winding direction (inward direction) of the rotary rake from the connecting shaft (8). A grass collecting unit (13) αJ' consisting of fixed type tines is provided on both sides, and a curtain 04) is installed between both rotary rakes Uaυ' so that the collected grass becomes uniform without being tangled. At the rear end of the α force, a windrow (7-shaped grass division plate (16)) is provided to prevent the central part from rising.

The second embodiment shown in FIGS. 5 and 6 utilizes a grass collection chute αηαη' consisting of a rotary type main body whose tip of the tine lands on the ground and rotates by forward force.

In the figure, 09 indicates a caster wheel whose height can be changed according to the main height, and 09 indicates a twine (thread).

[For production]

The roll baler with a rake according to the present invention moves forward as a whole by being pulled by the tractor (6).
The rotary rakes αυ' on both sides rotate in the raking direction due to the power received from the power take-off α0) of ), rolling the windrow α9, and the roll baler body (9) moves forward while also moving from the same power take-off (10). The cylindrical roll-formed package is operated by the received power, and furthermore, the grass divider plate αe installed at the rear position between both rotary rakes αυaυ functions to prevent the central part of the windrow α9 from being raised. In addition, the roll roller body (9
), the grass collection chutes αJα3'CIHη' installed on both sides of the front position of the pick amplifier (5) are connected to the windrow -α
It functions to shape the both side edge fixing Mts" of the roll baler body (9) into an upright state with respect to the ground, and these two functions form a windrow α9 with a substantially rectangular cross section that matches the chamber width of the roll baler body (9). and enters the chamber (2) through the pickup (5) at a uniform density.

〔Effect of the invention〕

Since the present invention has the above-described configuration, one worker can perform grass collection work and packing work in one trip,
Moreover, it is possible to easily and reliably obtain a cylindrical roll-formed package, and it has an excellent effect of completely achieving the intended purpose.
