The winding body 21 is rotatably driven in the winding direction (the direction indicated by the arrow A in FIG. 3) by being interlocked and connected by the first transmission means 25 including a transmission mechanism.

By the rotation of the winding body 21, the agricultural film body F is pulled up from the ridge R and wound around the winding rod 21B to be collected. The winding rod 21B is provided detachably with respect to the rotating body 21A, so that the agricultural film body F wound on the winding rod 21B can be easily removed. The left and right holders 18 are provided with amplitude means 26 via brackets 27 extending rearward and downward.

The amplitude means 26 pivotally connects the rear ends of a pair of left and right swing arms 29 to the lower end of a bracket 27 via a fulcrum shaft 28, and the front ends of the left and right swing arms 29 have vertical amplitude motion. The amplitude body 30 which shakes off the impurities etc. on the agricultural film body F by erection is constructed, and the amplitude body 30 is arranged such that the left and right center portions are located at the front and the left and right ends are located at the rear. It is formed of a bar having a mountain shape in plan view, and guides the agricultural film F in a form of scooping up the agricultural film F from below. The front and rear halfway portions of the left and right swing arm 29 are connected to each other by a connecting rod 31. On the other hand, a bearing 32 is fixed between the front frame 4 and the toolbar 6 in the front and rear directions. Power intake shaft 3

The distal end of the power take-in shaft 33 and the PTO shaft 8A of the tractor 8 are linked to each other via a universal joint and a transmission shaft 38. Thus, the power take-in shaft 33 is rotated by the power transmitted from the tractor 8 around the longitudinal axis, and the rotation causes the connecting rod 31 to move up and down via the crank body 37, and the vertical movement causes the swing arm 29 to move.
And the amplitude body 30 reciprocally swings (amplitude) up and down around the fulcrum shaft 28, and the mountain-shaped amplitude body 3 in a plan view.
With 0, the contaminants and the like on the membrane F are shaken off while moving so as to flow to the left and right sides.

The amplitude means 26 is connected to the electric motor 2.
4 and can be operated not only at the time of work by the winding and collecting device 2 but also at the time of work by the peeling device 1 described later. As shown in FIGS. 1 and 2, the peeling device 1 includes a holding means 40 for holding the agricultural film body F covered with the ridge R from above and below while pulling up from the ridge R;
And a pull-in means 41 for pulling the agricultural membrane F into the housing. The holding means 40 sandwiches the agricultural film F in cooperation with the lower holding roller 42 by contacting the upper surface of the agricultural film F with the lower holding roller 42 that supports the lower surface of the agricultural film F from below. The lower holding roller 42 is configured by the guide body 20 rotatably supported by the machine frame 7.

As a result, a part of the stripping device 1 and a portion of the winding and collecting device 2 are shared, so that the structure can be simplified and the cost can be reduced by reducing the number of parts. A front end of a support arm 44 is supported on the rotation shaft 21C of the winding body 21 so as to be vertically swingable, and a rear end of the support arm 44 is provided with one end (left end) of a left-right rotation shaft 45. It is rotatably supported, and the other end (right end) of the rotating shaft 45 is
The upper holding roller 43 is attached and fixed. Also,
A bracket 46 (see FIG. 2) projecting inward and rightward (rightward) is fixed to a middle portion of the support arm 44, and a support frame 47 having a portal shape in plan view is attached to an end of the bracket 46. The rotary shaft 45 is rotatably supported at both ends of the support frame 47 via bearings, and the upper holding roller 43 is disposed inside the gate of the support frame 47.

The rotating shaft 21C of the winding body 21 and the rotating shaft 45 of the upper holding roller 43 are linked and connected by a second transmission means 48 comprising a chain transmission mechanism. Is transmitted to the rotation shaft 45 of the upper holding roller 43 via the first transmission means 25 in the transmission case 23, the rotating shaft 21C of the winding body 21, and the second transmission means 48, and the upper holding roller 43 is Arrow B direction (retraction direction)
The pull-in means 41 is constituted by rotating the upper holding roller 43 in this manner.

Accordingly, the agricultural film F is sandwiched between the upper and lower sandwiching rollers 42, 43, and the upper sandwiching roller 43 is indicated by an arrow B.
By rotating and pulling in the direction (retraction direction),
Water droplets and the like adhering to the agricultural film body F can be squeezed out by the pinching action and suitably removed. At this time, since the lower sandwiching roller 42 has a length substantially covering the width of the agricultural film F, it can reliably support the agricultural film F from below and guide it backward. The upper holding roller 43 that is driven to rotate is formed to have a larger diameter than the lower holding roller 42, so that the winding of the agricultural membrane F can be prevented as much as possible.

Although the upper holding roller 43 comes into contact with the lower holding roller 42 by its own weight, an external force in the contact direction may be applied by an urging member such as a spring. Further, the outer peripheral surface of the upper sandwiching roller 43 is preferably formed of a non-slip material such as rubber or resin, and it is preferable to prevent unevenness by forming irregularities or the like on the outer peripheral surface. The rotating shaft 45 of the upper holding roller 43 and the second transmission means 4
A clutch 50 is provided between the sprocket 8 and the sprocket 8 so as to connect and disconnect the power transmission therebetween. The clutch 50 can be turned on and off by a clutch lever 51 provided on the bracket 46. When performing the work, the clutch 50 is disengaged so that the upper holding roller 4
3 is stopped so that unnecessary power transmission is not performed.

When the peeling device 1 is not used, for example, when the work is performed by the winding and collecting device 2, the upper holding roller 43 can be evacuated by swinging the upper holding roller 43 upward through the support arm 44. Therefore, a holding member 52 for holding the upper holding roller 43 in the retracted state is provided. The holding member 52 is formed by a bent link provided between a bracket 46 fixed to the support arm 44 and the toolbar 6, and is bent upward when the upper holding roller 43 is lowered as shown in FIG. When the upper holding roller 43 is raised as shown in FIG. 3, the upper holding roller 43 is bent downward in a reversely bent manner, and the upper holding roller 43 is held at a predetermined height. , Its bending limit is set.

The operation of raising and lowering the upper holding roller 43 can be easily performed by using the gate-shaped support frame 47 as a handle, and since the support frame 47 surrounds the outer peripheral portion of the upper holding roller 43, It has a function as a guard for preventing the agricultural film F from winding around the upper holding roller 43. One mode of the operation of the stripping device 1 described above will be described. The longitudinal end of the agricultural film F covered with the ridge R is manually pulled up and passed through the upper side of the amplitude body 30, and the upper and lower holding rollers 42, 43. By driving the amplitude means 26 and the retracting means 41 (upper sandwiching roller 43) while running across the ridge R by the tractor 8, the amplitude means 26 lifts the agricultural film F from the ridge R, The soil, foliage and the like on F are shaken off, and water droplets and the like adhering to the membrane F are removed behind the F so as to be squeezed out by the clamping action of the clamping means 40.

At this time, before the agricultural film body F reaches the holding means 40, the amplitude means 26 shakes off the impurities on the agricultural film body F as much as possible.
It is less likely that foreign matter or the like is caught in between. In addition, while the agricultural film F is held by the holding means 40, the amplitude of the agricultural film F is vertically moved by the amplitude means 26 in front of the film F, so that the film F can be reliably peeled off from the ridge R. It has become. Then, the agricultural film body F that has been peeled off from the ridge R and passed through the holding means 40 is dropped again on the upper surface of the ridge R or the groove between the ridges R.

The agricultural membrane F thus peeled off from the ridges R
Since it has been spread to some extent in the longitudinal direction, it can be dried in a relatively short time even in a slightly wet state, and as a post-processing, it can be collectively collected manually, It is also possible to take up and collect by the winding and collecting device 2. In the case of collecting by the winding and collecting device 2, the upper holding roller 43 is swung upward to the retreat position, and the clutch 50 is disengaged by the clutch lever 51 to cut off the power transmission to the upper holding roller 43. It is assumed that winding and collection are performed in the state of being wound.

In this case, since foreign substances and water droplets on the agricultural membrane have been almost completely removed by the stripping operation in the previous step, it is almost impossible to collect them while entraining them. The body can be continuously wound without breaking the body, and post-processing after collection can be suitably performed. Stripping device 1
As another working mode, the peeling work can be performed in a stationary state without running the tractor 8.
In this case, the agricultural film F is pulled backward by being pulled in by the pull-in means 41 while holding the agricultural film F by the holding means 40, and the peeled agricultural film F is moved to the holding means 40. After passing through, they are collected at one location, and can be easily collected manually.

FIG. 4 shows a second embodiment of the present invention. The peeling device 1 of this embodiment is the same as the above-described embodiment in that it has a holding means 40 and a pull-in means 41, but each of these means 40 and 41 and a drive source 5

The front end of the holding frame 56 is detachably attached to an appropriate position of the machine frame 7 of the winding and collecting apparatus 2 via a fastener 59 such as a bolt. The lower holding roller 42 is arranged at an interval allowing passage of the agricultural film F at the time of winding and collecting or at the time of stripping operation.

The operation of the stripping device 1 and the winding and collecting device 2 in the present embodiment is the same as that of the above embodiment, but the device unit 55 of the present embodiment is not limited to the winding and collecting device 2 and can be used for harvesting. It can also be used by attaching it to other working devices such as machines and management machines. In addition, it can be used in cooperation with other working devices, or can be used simply by using the traveling devices of these working devices. Further, the device unit 55 can be used alone by being mounted on a traveling vehicle 8 such as a tractor.

The design of the present invention is not limited to the above embodiment, and the design can be changed as appropriate. For example, the pull-in means 41 is constituted by rotating only the upper and lower nipping rollers 42, 43 or only the lower nipping roller 42. And freely support the upper and lower nipping rollers 42 and 43,
