Description
Technical field
The present invention relates to agricultural mechanical field, especially a kind of automatic film cutting device of film-laying machine.
Background technology
Development along with agricultural machinery, agricultural machinery product constantly is applied in the actual production, in recent years, film-laying machine progressively enlarges in field of planting and the area applications of crops, especially the tobacco planting of southern area, traditional manual epiphragma is just progressively replaced by mechanical epiphragma, but existing film-laying machine can only epiphragma, must the people manually mulch film be cut during to the edge of a field, and effort is taken a lot of work, labour intensity is large, inefficiency.
Patent publication No. is " CN100479648C ", name is called " antomatic mulch-cutting device of mulch-covering machine ", a kind of antomatic mulch-cutting device of mulch-covering machine is disclosed, comprise cutting membrane knife, the blade of cutting membrane knife is the rip dentation, set up transverse axis and two cover pulley gears, the first set pulley gear comprises the large pulley with handle, helical gear and the helical gear ratchet of control, the second cover pulley gear comprises three pulleys, wherein transverse axis is fixed on the crossbeam of plastic mulching machine through bearing block, the centre of transverse axis and two ends all are fixed with pulley, large pulley and helical gear are installed in the top of crossbeam with the beam warp support, and large pulley and the pulley that is positioned in the middle of the transverse axis share a steel wire, the pulley that is positioned at the transverse axis two ends respectively is connected with cutting membrane knife through a length-adjustable steel wire, and the two ends of cutting membrane knife all are fixed with thin bar, are set with spring on the thin bar, its other end is through on the fixed cover that is fixed on the crossbeam, and turning to of two cover pulleys is consistent.When cutting film ratchet is moved, large pulley rotates, thereby the pulley on the transverse axis rotates, and removes spring force, and cutting membrane knife cuts off mulch film; Although adopt this film mode of cutting can satisfy the requirement that machine automatization is cut film, because this scheme has following shortcoming:
1, block the mode fixed cutting tool position of large pulley by ratchet, need in use often ratchet to be moved, then because the gravity of gravity and cutting membrane knife realizes cutting film, whole dynamics of cutting film is little, can not be fully with the membranectomy on the furrow of whole ridge.
2, ratchet in use needs constantly and the large pulley cooperation, uses long afterwards, the phenomenon of tooth occurs easily taking off, and causing cutting membrane knife is to fall in the situation of needs, causes the damage of whole crops.
3, after decontroling ratchet, mainly be to utilize the restoring force of spring that film is cut off, whole spring need to be in compressive state always, the strain of spring is easy to become plastic deformation, cause cutting the decline of film power, its operation quality is reduced, overall work is reliable and stable not.
4, cut and need behind the film cylinder by artificial turning handle whole cutting membrane knife to be mentioned in the large pulley counter-rotating, blocking large pulley with ratchet, whole process is complicated, and the labour who needs is many.
