Description

Antomatic mulch-cutting device of mulch-covering machine

Affiliated technical field

The invention provides a kind of antomatic mulch-cutting device of mulch-covering machine, belong to agricultural machinery technological field.

Technical background

Present automatic shop membrane technology is fairly perfect, but does not have automatic film cutting apparatus, is artificial dyestripping mostly or manually assists with extremely simple and crude knife saw and to cut film, and is more time-consuming, takes a lot of work; And be to spread film, mechanical work automatically now mostly, so artificial dyestripping and irrational mechanical slit film tapes have certain danger, and it is poor to cut film quality, effect is undesirable, easily causes the film waste.

Summary of the invention

The purpose of this invention is to provide a kind of can overcome above-mentioned defective, simplicity of design, easy to use, be easy to the supporting use of plastic mulching machine, cut the respond well antomatic mulch-cutting device of mulch-covering machine of film, its technical scheme is:

Comprise cutting membrane knife, it is characterized in that: the blade of cutting membrane knife is the rip dentation, set up transverse axis and two cover pulley gears, the first cover pulley gear comprises the large pulley that has 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 be positioned at being centered close on the same vertical line of pulley in the middle of the transverse axis, both shared steel wires, 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, be set with spring on the thin bar, its other end is through on the fixed cover that is fixed on the crossbeam, play the guiding role, and two overlap the unanimity that turns to of pulleys.

Described antomatic mulch-cutting device of mulch-covering machine, cutting membrane knife connects firmly on a tool rest, fixedly connected with tool rest in the bottom of thin bar, be provided with the steel wire ring corresponding to pulley on the tool rest, steel wire from pulley passes the steel wire ring, be fixed on the wire clip, can adjust cutting membrane knife and be in when slinging state height apart from mulch film by adjusting wire clip.

Its operation principle is: large pulley is fixed on the support with helical gear is coaxial, when film cutting apparatus is in off working state automatically, ratchet is stuck on the helical gear, and then firmly with the large pulley prevention, whole device is in the suspension status of other operations such as not influencing sowing, overlay film, the spring that be sleeved on the thin bar this moment is in stressed compressive state, and cutting membrane knife is mentioned the top that is positioned at mulch film.When cutting film, to block helical gear ratchet moves, large pulley rotates, rotate synchronously with the middle pulley of transverse axis that is positioned at of the shared steel wire of large pulley, other two pulleys that are installed on the same transverse axis also rotate synchronously, because two pulleys respectively are connected with cutting membrane knife through a length-adjustable steel wire, so connecting the steel wire of cutting membrane knife rotates with pulley, the resistance of spring is removed, cutting membrane knife tangentially is layered on film on the ground under the effect of spring force fast and with its cut-out, turning handle makes the large pulley counter-rotating then, drives three pulleys that are installed on the transverse axis and reverses synchronously, connect the steel wire upset of cutting membrane knife, cutting membrane knife is mentioned, and the spring compression is blocked helical gear with ratchet again, whole device is in treats duty, finish and once cut the film action.

The present invention compared with prior art has the following advantages:

1, owing to designed pulley structure, utilization flexibly connects, and is easy to realize, regulates also very simple, dismounting and keep in repair also very convenient;

2, cutting membrane knife adopts the form of sawtooth, and relatively safety is equipped with spring above, utilizes spring force to be used as cutting the power of film, makes that to cut film accurately quick, and spring is easy to disassembling, assembling and replacing, and it is very convenient to safeguard.

3, the package unit design is rationally simple and clear, flexibly connects to make installation requirement lower, can satisfy the needs that machinery is cut film automatically fully, and the efficient of sowing shop film is improved, and satisfies the agriculture requirement of integration of operation, and the operation quality height is stable and reliable for performance.
