PURPOSE:To obtain the subject new device, composed of a specific construction capable of performing grass collecting operation in its state connected to a tractor and a roll baler and capable of carrying out grass collecting operation and packaging operation of pasture grass without performing reconnecting operation. CONSTITUTION:A traction lever 3 installed in rotary rake bodies is driven by the rotation of a power shaft 5 is initially connected to a tractor 1 and the power shaft 5 is simultaneously connected to a power takeoff of the tractor 1. Furthermore, a connecting shaft 17 of a roll baler 15 is connected to a joint part 12 for transmitting the rotation driving power provided at an extension end in which the rear end of the power shaft 5 is extended to the rear and a traction lever 16 for connecting the roll baler 15 is connected to a joint part 13 for transmitting the traction force installed at an extension end in which the rear end of the traction lever 3 is extended to the rear. Rotary rake devices and the roll baler 15 are successively connected to the rear of the tractor 1. In their state, they are traveled to simultaneously perform grass collecting and packaging operations.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary rake device for collecting grass.

[0002]

2. Description of the Related Art Conventionally, grass collecting work and packing work have been performed by the following replacement method, for example. That is, after performing work for collecting grass (windrow) with a rake, the rake was removed from the tractor, and instead, a roll baler was connected to the tractor for packing work with the roll baler.

[0003]

However, the splicing method described in the above prior art is not preferable because the splicing operation takes a lot of time and labor. It is an object of the present invention to provide a novel rotary rake device which is devised so that it does not take time and effort when used.

[0004]

In order to achieve the above object, a rotary rake device according to the present invention includes a tow rod towed by a tractor and a power shaft connected to a power take-off of the tractor. The rotary rake body consists of a pair of left and right driven by rotation, the rear end of the power shaft is extended rearward, the rotary drive force transmission joint is provided on the extended end, and the rear end of the towbar is extended rearward. It has a traction force transmitting joint portion provided at the extension end.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment shown in the drawings comprises a towing rod 3 having a connecting portion 2 for connecting to a tractor 1 at its tip and a power shaft 5 for connecting to a power take-off 4 of the tractor 1, and the rear end of the towing rod 3. It is possible to adjust the left-right distance with the mounting arms 22 and 23 that can be expanded and contracted on both left and right sides, and to lift up to the upward position (see the phantom line in FIG. 3) by the hydraulic cylinders 6 and 7 without stopping the rotation of the power shaft 5. As a pair of left and right rotary rakes 8, 9
The rake main body is provided with a gear device 10 for transmitting a rotational force at the rear end of the power shaft 5 so that the rotary rakes 8 and 9 receive the rotational force in the winding direction (inward direction) from the power shaft 5. 11, the rear end of the power shaft 5 in the rake body 11 is extended rearward, and the joint portion 12 for transmitting the rotational driving force is provided at the extended end.
Similarly, the rear end of the towbar 3 is extended rearward, and a traction force transmitting joint portion 13 is provided at the extended end.

Reference numeral 15 in the drawing is a commercially available roll baler having a tow rod 16 connected to the tractor 1 and a connecting shaft 17 to the power take-off 4 of the tractor 1, which can be used alone and connected to the tractor 1. , A two-split discharge type bale chamber 19 provided with a tire 18 on the lower surface in a load center arrangement, a large number of convex forming rollers (not shown) provided around the inside of the chamber 19, and a pick-up port. The pick-up device 20 provided in the, a compressor (not shown) that can be adjusted according to the amount of processing, a feeder rake (not shown) that forcibly conveys the processed material picked up by the pickup into the bale chamber 19, and a bobbin winding operation. It is equipped with an automatic twine device (not shown) and the like.

[0007]

In the rotary rake device according to the present invention, for example, the tip of the tow rod 3 and the tip of the power shaft 5 are connected to the tractor 1 and the tractor 1 which the roll baler 15 has with respect to the joint 13 for transmitting the traction force.
To the tractor 1 of the roll baler 15 with respect to the joint portion 12 for transmitting the rotational driving force, and the tip of the connecting shaft 17 to the tractor 1 connected to the rotary drive force transmission joint 12, respectively. Inventive rotary rake device and a commercially available roll baler 15 are connected to each other and run, so that they can be used for such operations as performing grass collecting work and packing work continuously at one time.

Instead of the roll baler 15, another machine may be appropriately connected to perform a plurality of operations in a series of states.

[0009]

INDUSTRIAL APPLICABILITY The rotary rake device according to the present invention has the above-mentioned construction and can be used for the above-mentioned usage. It is possible to replace a plurality of works such as grass collecting work and packing work. The present invention has a convenient effect that it can be performed all at once without performing any operation.
