Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a multi-film collecting device for collecting multi-film coated on the upper surface of a ridge.

[Prior art] There is a laying machine that covers the top surface of the ridge with a thin vinyl film for the purpose of maintaining soil temperature and preventing moisture evaporation, but there is no machine that takes advantage of the opportunity to collect this film. .

In recent years, so-called full-surface mulching machines that apply mulch film over the entire surface of the ridges to prevent weeds from growing have become popular. To prevent it from being blown away, soil must be poured into both ends and the center of the mulch film to hold it down. When collecting the mulch film after harvesting the crops, the worker must manually pull the mulch film together while removing the soil, taking care not to break the mulch film.

[Problems to be solved by the invention] As described above, in the past, multi-film was collected manually, which required a great deal of labor.
Collection work was extremely difficult as a large amount of soil accumulated on the mulch film, and the mulch film sometimes tore during the process, reducing efficiency.

[Means for Solving the Problems] The present invention is proposed in view of the above-mentioned problems, and takes the following technical measures.

That is, a film winding body 27 that is attached to the mobile agricultural machine 1 and winds the multi-film a covering the ridges;
The winding body 27 receives the rotational power from the mobile agricultural machine 1 side.
The winding body 27 is located in the power transmission path of the power transmitting parts 7, 8, and...
The multi-film collecting device has a sliding mechanism section 22 that can transmit power while sliding it.

[Example] Hereinafter, an example of the present invention will be described based on the drawings. First, to explain the configuration, 1 is a tractor, and two lower links 2, 2 are pivoted to the rear of the machine so that they can be raised and lowered, and a horizontal shaft 4 is attached to the rear end of the lower links 2, 2. A film recovery device 6 is connected to the shaft 4. A gear case 5 is attached to the upper part of the pedestal 3 of the film recovery device 6, and an input shaft 7 is mounted on the gear case 5 so as to project forward.

A bevel gear 8 is provided at the rear end of the input shaft 7, and this bevel gear 8 is connected to a bevel gear 1 on a shaft 10 installed horizontally in the gear case 5.
2 are always engaged. A clutch case 15 is fixed to the side of the gear case 5.

A plurality of driving blades 16 are attached to the end of the shaft 10, and a plurality of driven blades 17 are provided so as to surround the driving blades 16.
A rotating shaft 20 is integrally provided at the end of 7. The driving blade 16 and the driven blade 17 are housed in a clutch case 15, and the clutch case 15 is filled with fluid so that power is transmitted from the driving blade 16 to the driven blade 17 via the fluid. It is composed of In this embodiment, the input shaft 7, bevel gears 8, 12, shaft 10, etc. are referred to as a power transmission section 14, and the drive blade 16, driven blade 17, and fluid are collectively referred to as a sliding mechanism section 22.

Bearings 25 and 26 are provided on the upper surface of one side of the pedestal 3 and the upper surface of a support base 24 provided on one side of the pedestal 3, respectively.
A take-up roll 27 driven at zero is supported. A rolling wheel 29 that is located immediately in front of the take-up roll 27 and contacts the film from below the multi-film a is supported by a support rod 30 that is L-shaped in plan view.
is removably inserted into a cylindrical body 32 fixed to the entire base 3. 33 is a fixing screw for fixing the support rod 30. In addition, the reference numeral 35 in the figure is the power take-off shaft (PTO shaft) of the tractor 1, 37 is the universal joint, and 40 is the multi-film a.
This is the soil that was dropped on top of the earth.

Next, the operation of the above embodiment will be explained.

When the power take-off shaft 35 of the tractor 1 is rotated, the power is transferred to the universal joint 37,
Shaft 1 via input shaft 7 and bevel gears 8 and 12 in sequence.
The signal is transmitted to the drive vane 16 which is fixed at zero. Then, when the drive blade 16 rotates, the driven blade 17 starts rotating via the fluid, and the take-up roll 27 is rotationally driven.

The multi-film a is taken up by the rotation of the take-up roll 27, but as the amount of take-up increases and the rotation diameter increases, the take-up speed increases even if the number of revolutions of the roll 27 is constant. , the traveling speed of tractor 1 becomes out of synchronization. However, in this embodiment, since the fluid is interposed between the driving blade 16 and the driven blade 17 as the sliding mechanism 22, when the amount of movement of the tractor 1 and the amount of film winding do not match, the amount of movement of the two The rotation of the rotating shaft 20 is decelerated due to slipping between the two, and it becomes possible to wind up the multi-film a in accordance with the traveling speed of the tractor 1 without cutting the multi-film a.

Further, in this embodiment, the central part of the multi-film a is lifted up by the roller 29, so that the film a
Since the film is rolled up, the soil dropped in the center can be easily discharged to the sides, and the winding and collection work is simplified. [Effects of the Invention] The film collection device according to the present invention , as described above, a film winding body that is attached to a mobile agricultural machine and winds up the multi-film coated on the ridges; a power transmission unit that receives rotational power from the mobile agricultural machine and rotationally drives the winding body; Since it consists of a sliding mechanism part that is located in the transmission path of the transmission part and can transmit power to the winding body while sliding it, the multi-film stripping work can be done without any effort and work efficiency is improved. improves.

In addition, even if the amount of travel of the mobile agricultural machine and the amount of winding of the multi-film do not match, slipping will occur due to the operation of the sliding mechanism, so the multi-film will be appropriately tensioned, and the multi-film will loosen in the middle. On the contrary, the winding operation can be carried out smoothly without being pulled too hard and being cut.
