Description

[Detailed description of the invention] This invention continuously delivers a sheet to cover high ridges for tobacco cultivation, stretches the sheet over the surface of the ridge, and pushes both edges of the sheet into the soil on both sides of the ridge. In a structure in which the embedding drum is inclined in a direction crossing the slopes of both sides of the ridge, a bridge is provided for the upper eyelid to be inserted into the sheet embedding groove formed at the same time as the ridge is formed, and the upper eyelid is provided with a notch at the rear of the bridge. The present invention relates to an improvement of a device configured to project the lower part of the embedded drum downward through the embedding drum.

By inserting the embedding drum into the sheet embedding groove through the notch in the bridge, the upper eyelid can insert the side edges of the sheet into the embedding groove with a small force, thereby applying appropriate tension to the sheet, which is easily torn. By applying force, it can be brought into close contact with the ridge surface.

However, when starting work and adding sheets, it is troublesome for the upper eyelid to have the leading edge of the sheet sandwiched between the bridge and the embedding drum, and the upper eyelid is used to set the relative support height of the embedding drum to the bridge. There were drawbacks such as difficulty in

The present invention has been improved in order to eliminate the above-mentioned drawbacks, and the upper eyelid is rotatably attached above the front of the bridge at the top, middle and bottom of the front end of the swinging frame, and the embedded drum is pivotally supported at the rear end of the swinging frame. In addition, a spring that pushes down the embedded drum is connected to the swing frame, and a lever that lifts the embedded drum is connected to the swing frame, and the swing frame is raised and lowered through the lever. For the eyelid, the embedded drum can be easily attached and removed from the notch in the bridge, and for the upper eyelid, the starting edge of the sheet can be easily sandwiched between the bridge and the embedded drum, improving work efficiency, and By constantly pushing down the embedded drum supported by the bridge with a spring, the upper eyelid can be moved smoothly into and out of the underside of the bridge in response to changes in the depth of the seat embedding groove and the hardness of the cultivated soil. An object of the present invention is to provide a sheet covering device for ridges in which the upper eyelid can easily set the relative support height of the embedded drum with respect to the bridge, and the sheet can be properly tensioned and held by the embedded drum. .
