JPH03262422A - Recovery system of laid mulching film - Google Patents

Abstract

PURPOSE:To provide the title system capable of smooth winding recovery, so designed that a falling/removing mechanism for soil and residual crop using vibration is set up between a mulching film-cutting mechanism and a winding roll being in traction by a running truck and to wind a mulching film laid on a farm. CONSTITUTION:After the starting part of a mulching film 1 laid on a farm is hung in a partly wound manner on winding rollers 2, 2, a recovering equipment is put to traction by a running truck such as a tractor, and the mulching film 1 is cut with a disc edge 3a of such a cutting mechanism located before the winding rollers as to cut such film into plural ribbons at the respective raising hole positions and at the center between both levees. The resulting ribbons are passed through a falling/removing mechanism 4 for soil and residual crop by application on said ribbons of vertical vibrations through a cam 30 set up between the winding rollers 2 and the cutting mechanism 3, and the ribbons freed from the above impurities are wound on the winding rollers 2, thus accomplishing the objective recovery.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a recovery device for laid mulch film.

PRIOR ART AND PROBLEMS TO BE SOLVED BY THE INVENTION In a mulch film recovery device that has a take-up roller that peels off and winds up mulch film that has been laid on a field while being towed by a traveling vehicle body, There are soil, residual crops, etc. on the surface of the film, but if you wind up these residual crops with the mulch film on the winding roller, the remaining crops, etc. will interfere with the winding. If the mulch film is difficult to clean, and residual crops are present in the mulch film after being wound into a roll, the roll of mulch film will become too tall and heavy, which is undesirable in terms of disposal of the mulch film.

Means for Solving the Problems The present invention includes a winding roller 2 that winds up a mulch film 1 laid out in a field while being towed by a traveling vehicle body, and a winding roller 2 that winds up a mulch film 1 that is located in front of the winding roller 2.
A removing mechanism 4 is provided between a cutting mechanism 3 that cuts the mulch film into a plurality of strips and a removing mechanism 4 that vibrates the mulch film 1 being rolled up to remove soil, remaining crops, etc. The configuration of the device.

Effect of the Invention When the recovery device is towed by a traveling vehicle body, the laid mulch film 1 is cut into a plurality of strips by the cutting mechanism 3, and is vibrated by the removal mechanism 4, thereby removing soil and remaining residue on each mulch film 1. The crops, etc. fall and are removed from both the left and right edges and the cut section, and are wound up on the winding roller 2.

Effects of the Invention In this way, the soil and remaining crops from the mulch film being rolled up are forcibly removed, so the winding is not obstructed by the remaining crops, and therefore the mulch film is rolled up. In addition to smooth winding and collection on the winding roller 2, since there is no residual crop etc. between the rolled mulch film 1, the rolled mulch film 1 does not become too tall.
There is no risk that the weight will increase, and therefore it is also preferable for disposal after being rolled up and collected.
