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
Along with the development of agricultural machinery, agricultural machinery product is constantly applied in actual production, in recent years, film-laying machine progressively expands in the field of planting of crops and area applications, the especially tobacco planting of southern area, traditional manual epiphragma just progressively replace by mechanical epiphragma, but existing film-laying machine can only epiphragma, and must people manually be cut by mulch film to during the edge of a field, 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 ", disclose a kind of antomatic mulch-cutting device of mulch-covering machine, comprise cutting membrane knife, the blade of cutting membrane knife is rip dentation, set up transverse axis and two cover pulley gears, first set pulley gear comprises the large pulley with handle, helical gear and the helical gear ratchet of control, second cover pulley gear comprises three pulleys, wherein transverse axis is fixed on the crossbeam of plastic mulching machine through bearing block, centre and the two ends of transverse axis are all fixed with pulley, large pulley and helical gear with beam warp support installing above crossbeam, and large pulley shares a steel wire with the pulley be positioned in the middle of transverse axis, the pulley being positioned at transverse axis two ends is respectively connected with cutting membrane knife through a length-adjustable steel wire, the two ends of cutting membrane knife are all fixed with thin bar, thin bar is set with spring, its other end is through on the fixed cover that is fixed on crossbeam, turning to of two cover pulleys is consistent.Moved by ratchet when cutting film, large pulley rotates, thus the pulley rotation on transverse axis, remove spring force, mulch film cuts off by cutting membrane knife; Although adopt this film mode of cutting can meet the requirement that machine automatization cuts film, because this scheme has following shortcoming:
1, blocked the mode fixed cutting tool position of large pulley by ratchet, need in use often to be moved by ratchet, then because the gravity of gravity and cutting membrane knife realizes cutting film, whole dynamics of cutting film is little, can not fully by the membranectomy on the furrow of whole ridge.
2, ratchet in use needs constantly and large pulley cooperation, uses long afterwards, easily occurs the phenomenon of de-tooth, causes cutting membrane knife to be fall in case of need, cause the damage of whole crops.
3, when after relieving ratchet, mainly utilize the restoring force of spring to cut off film, whole spring needs to be in compressive state always, the elastic deformation of spring is easy to become plastic deformation, cause cutting membrane forces decline, its operation quality is reduced, and overall work is reliable and stable not.
4, need cylinder by manual rotation's handle, large pulley to be reversed after cutting film to be mentioned by whole cutting membrane knife, blocking large pulley with ratchet, whole process is complicated, and the labour of needs is many.
