The agricultural machine for gathering of the plastic films for covering the mulching culture

摘要

The machine consists of a rolling base (10), trailed behind a tractor, and which carries a series of devices, which act in sequence relevant to the direction of travel of the machine. First the device of unearthing (20a & 20b) the edges of the plastics film (F). Secondly, the rolling axle (30) to ensure the transport of the machine. Thirdly, the primary extraction station, with rotary drive to extract the plastic film and this is followed by the second extraction station (5), designed to enrol the film on to the roll (51). The un-earthers (20) are formed by two cylindrical teeth (20a and 20b), with pointed ends, which are mounted parallel to each other and at an adjustable height on the base. Each tooth comprises a primary vertical section (201a, 201b) to ensure the mounting of the teeth, followed by a second section (202a ,202b), which bent towards the centre of the frame, to ensure that the film is lifted and to clear the earth. The final section (203a,203b) is bent towards the front of the machine and downwards to ensure that the teeth engage the film under the ground.
