Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stripping machine for stripping a multifilm from a bag in advance when collecting the multifilm.
[0002]
[Prior art]
When collecting the multi-film, if the multi-film is peeled off from the bag and immediately wound, there is a problem that the multi-film cannot be efficiently wound because moisture or soil is attached to the multi-film. In addition, if the multi-film is left with moisture or soil, there is a problem that disposal costs increase. For this reason, the multi-film is once peeled off from the basket and dried, and then collected.
[0003]
As a conventional multifilm stripping machine for stripping a multifilm, an agricultural covering sheet stripping device 51 described in Patent Document 1 is exemplified. As shown in FIG. 6, the device 51 is connected to and supported by the rear portion of the tractor 61, and is moved in parallel along a multi-film (multi-sheet) S to be peeled off. The laid multifilm S is pulled up in the transverse direction with respect to the longitudinal direction, discharged from the lower surface of the housing 56, and dropped onto the adjacent ridge.
[0004]

Utility Model Registration No. 3031248 [0005]
[Problems to be solved by the invention]
However, since the conventional peeling device 51 is connected to the tractor 61 and performs the peeling work, there is the following problem.
[0006]
(1) Since the multi-film S is pulled up in the horizontal direction, the resistance at the time of peeling is large, so that the multi-film S is broken if the traveling speed of the tractor 61 is too fast. For this reason, the traveling speed of the tractor 61 has to be slowed down, resulting in poor working efficiency.
[0007]
(2) If the traveling speed of the tractor 61 and the stripping speed of the stripping device 51 do not match, the multi-film S is torn or the work cannot be performed efficiently.
[0008]
(3) Since the tractor 61, which is a mechanism for running the airframe, and the peeling device 51, which is a mechanism for peeling the multi-film S, are separately provided, the size increases and the structure becomes complicated. Costs are incurred. If the size is large, the stripping operation may not be possible, especially when the space between the ridges is narrow, or when there are remaining crops on the ridges, and the turning operation may be time-consuming.
[0009]
An object of the present invention is to solve the above-mentioned problems and to provide a multi-film stripping machine that can efficiently strip a multi-film with a simple configuration.

However, if the aircraft is advanced by human power, the wheels roll along therewith, so that the wheels need not be driven.
[0012]
The said wheel illustrates the aspect which is a rear wheel which supports the said body so that driving | running | working is possible.
[0013]
According to this configuration, since the mechanism for running the airframe is configured to act as a part of the mechanism for peeling the multi-film, the structure can be simplified and the cost can be reduced.
[0014]
The stripping portion has a roller that is rotatably supported around a shaft extending in the left-right direction, and exemplifies a mode in which the multi-film is hung on the roller and sent to the wheel.
[0015]
According to this configuration, the peel-off part can be realized with a simple configuration and can be realized at low cost.
[0016]
The aspect provided with the guide member which guides a multi film to the front of the said peeling part and / or the said wheel is illustrated.
[0017]
According to this structure, a multi film can be reliably processed by the said peeling part and the said wheel.
[0018]
The said wheel illustrates the aspect by which the protruding item | line which extended diagonally toward the center of the peripheral surface of the anti-rotation direction side from the both-sides edge of the peripheral surface was illustrated.
[0019]
According to this configuration, the multi-film can be brought close to the center in the width direction of the peripheral surface of the wheel by the ridges, and the multi-film can be surely stepped on by the wheel.
[0020]
The aspect provided with the pre-processing part for unraveling the foreign material adhering to the multi film in front of the said peeling part is illustrated.
[0021]
According to this configuration, the multi-film can be smoothly peeled off from the wrinkles by previously unraveling the contaminants attached to the multi-film.
[0022]

Thus, as shown in FIG. 5, the machine body 2 travels along the kite U, and as the machine body 2 advances, the multi-film S stretched on the kite surface is continuously peeled off and released into the cage. Go.
[0030]
According to the multi-film stripping machine 1 of the present invention configured as described above, the multi-film S is stripped upward by the stripping unit 5, so that the lateral direction as in the conventional example is performed. Compared with the case where it peels off, there is little resistance at the time of peeling off, and the multifilm S is hard to tear. For this reason, the stripping speed can be improved as compared with the case of stripping in the lateral direction. Further, the rear wheel 6 rolls on the ground as the airframe 2 advances, and continuously steps the peeled multifilm S on the ground, and peels off the multifilm S from the multifilm S. Directional tension can be applied continuously. For this reason, unlike the conventional example, the running speed and the stripping speed are inevitably linked. Moreover, since the multi-film stripping machine 1 of the present invention has a simple configuration as described above, it can be realized at a low cost.
[0031]
Further, the rear wheel 6 that supports the airframe 2 so as to be able to travel is used as a wheel for stepping the multifilm S against the kite U. That is, the mechanism that causes the airframe 2 to travel is a mechanism for peeling the multifilm S. Since it works as a part, the structure can be simplified and the cost can be reduced.
[0032]
Further, the peeling portion 5 has a roller 26 supported so as to be rotatable about an axis extending in the left-right direction, and is configured to feed the multi-film S on the upper side of the roller 26 to the rear wheel 6.
