BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an arrangement for recovering a multi-film simultaneously with excavation.

[0002]

2. Description of the Related Art Japanese Utility Model Laid-Open No. 2-100417 discloses a technique for collecting a multi-film simultaneously with excavation.
In this known technique, immediately after cutting the foliage of a tuber crop, the tuber is dug up by a conveyor body while winding the multi-film in parallel with the entire width. Also, Japanese Utility Model Laid-Open No. 2-17056 is known as a prior art, which discloses a dedicated machine for a self-propelled multi-film peeling apparatus.

[0003]

According to the above-mentioned known technique, Japanese Utility Model Application Laid-Open No. 2-100417, when the buried portions at the left and right ends of the multi-film are deep, or when dirt or contaminants adhere to the upper surface of the film, There is a problem such that it becomes difficult to wind up when staying. The latter Japanese Utility Model Laid-Open No. 2-17056 requires a dedicated device for multi-film peeling as a separate operation after the completion of the harvesting operation.

[0004]

In order to solve the above-mentioned problems, a machine frame, a horizontal tip metal having an oscillating action at the front end of the machine frame, and harvesting while sifting soil behind the tip metal. A conveyor body for conveying the article backward, a guide member for guiding the multi-film interlocking with the vibration of the tip metal, and a collecting device for forcibly winding the multi-film behind the guide member. A digging device is provided.

[0005]

The foliage of the present invention is introduced into the ridge where the foliage is cut in advance and the multi-film is divided from the center. Then, the both sides of the multi-film are gripped and guided to the collection device through the guide material. When the machine is advanced, the multi-film is slanted to the left and right at the same time as the harvesting operation, and the soil is removed by the vibration of the guide material, and the multi-film is taken up by the continuously driven recovery device. Even when the buried portions at both ends of the multi-film are tightly tightened, the buried portions are sequentially loosened by the vibration of the guide material and smoothly wound up.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration will be described with reference to the drawings embodying the present invention. This example was performed on garlic as a tuber crop. FIG. 1 is a perspective view of the present invention, showing a state of collecting multi-films. FIG. 2 shows the front of the main part. FIG. 3 is a side view showing power transmission.

Reference numeral 6 denotes a mounting frame, which is mounted on a three-point link of a tractor (not shown). The mounting frame 6 is connected to the left and right side walls to form the machine frame 1. The main mission 2 is disposed at the center of the mounting frame 6, and the conveyor body 3 is driven from the side case 15 on the side via a pipe frame.
Power is transmitted to the transmission 4 from the middle of the input shaft 8 of the main transmission 2 by the transmission band 18. The transmission is transmitted from the submission 4 to a drive shaft 10 that drives the left and right collection devices 5 via a bendable connection shaft 9. The collection devices 5 are arranged in a pair on the left and right sides, and the configuration thereof will be described particularly with reference to the front view of FIG.

Reference numeral 23 denotes a stay fixed to the machine frame 1,
The base of the drive shaft 10 that supports the recovery device 5 is rotatably supported. The collecting device 5 is a substrate 11 provided with a plurality of rims 13.
And an outer plate 12 that can be inserted into and removed from the drive shaft 10,
The fixing is performed by the pins 22. The rim 13 is the substrate 11
The mounting portion is freely fixedly formed with respect to the outer plate 1.
2 is fitted into the guide hole. The guide hole is formed in a long hole such that the tip approaches the axis. When the outer plate 12 is rotated to remove the wound multi-film, the rim 13 is tapered to be easily removed.

A slip clutch 24 is provided between the connecting shaft 9 and the drive shaft 10 so that the tractor speed becomes faster than the winding speed, or the reel diameter becomes larger in accordance with the winding amount with respect to the tractor speed, so that winding can be performed. When the speed is increased, the slip is adjusted appropriately.

Reference numeral 21 denotes a horizontal tip that digs under the tuber, and the left and right frames 19 vibrate up and down. Reference numeral 7 denotes a guide member which has a ring-shaped upper end, guides the passage through the multi-film, and connects it to the collecting device 5 described above.

Referring to FIG. 3, the power transmission of the main part will be described in detail. The input shaft 8 is inputted from the tractor PTO by a universal joint, and the transmission 4 is rotated by the transmission band 18 to decelerate and drive the collection device 5 via the connecting shaft 9 described above.

A cam body 14 provided on the input shaft 8 has an eccentric body and a base shaft 20 as a fulcrum.
The frame 19 is eccentrically moved to vertically vibrate the frame 19. 1
When the frame 9 vibrates up and down, the guide member 7 swings integrally via the link member 26.

In this embodiment, a garlic crop is described. However, the multi-film shown by a two-dot chain line in FIG. The holding soil at both ends is loosened and wound up, and the soil and contaminants on the upper surface of the multi-film are wiped off while being divided right and left.

[0014]

[Effect] With the above structure, at the same time as the tuber crop is harvested, the multi-film is washed off by interlocking the soil and contaminants with the vibration of the deposit, and does not require any special power, and is collected smoothly. You. Thereafter, the processing is extremely easy.
