Abstract

The invention discloses a cutting height-free harvester for Chinese leeks. The cutting height-free harvester for the Chinese leeks comprises a stand, a front wheel, a rear wheel, a motor or a combustion motor, a driving pulley, a driven pulley, a driving line wheel, cutting line wheels and a cutting line. The cutting height-free harvester for the Chinese leeks is characterized in that the integral stand is of a triangular structure; the upper plane of the stand and the ground form a certain included angle, and the included angle is greater than 0 degree but is not greater than 90 degrees; the motor or the combustion motor is fixedly connected onto the stand; an output shaft of the motor or the combustion motor is vertical to the upper plane of the triangular stand; a driver is arranged on the inclined plane of the stand; the driving pulley and the driven pulley form a step-up drive part; the cutting wire wheels are arranged at the front end of the harvester to form a cutting power drive part together with the driving line wheel and a tensioning line wheel; and the cutting line is wound on the driving line wheel, the cutting line wheels and the tensioning line wheel. Crops can be free of cutting height by using the harvester, and when the crops, such as the Chinese leeks and the like, are harvested, the cutting process requirement is met, the crop loss is reduced, and the crop harvesting rate is improved. The cutting height-free harvester for the Chinese leeks is also suitable for harvesting other various crops.

Description

A kind of stubble that cuts is zero Chinese leek reaping machine

Technical field

The present invention relates to a kind of crop harvesting machinery, especially a kind of cut surface that can make carries out along ground, and cutting stubble is zero Chinese leek reaping machine.

Background technology

Cutter sweep in existing crop (corn, wheat, the paddy rice etc.) grain header all adopts reciprocating knife, it drives from crank, do reciprocating linear motion by connecting rod band movable slider (cutter), cooperate with fixing cutter again and realize crop cutting (cutting of support is arranged); Mower (a kind of special grain header) just is used for cutting off green grass (not considering the state after green grass is cut), and its cutter sweep adopts rotation rigidity (or flexible) cutting knife, and during cutting, green grass is cut off (without supporting cutting) under the rotary cutter effect.But no matter be which kind of existing grain header all can not make its cut surface carry out (making the stubble that cuts of crop is zero) along ground.Therefore when the vegetables such as harvesting leek, celery, existing grain header all is not used.

Summary of the invention

It is zero Chinese leek reaping machine that purpose of the present invention provides a kind of stubble that cuts, cutter sweep adopts without cutter (namely without reciprocating knife, rotation rigidity or flexible cutter,) form, namely use sealing cutting of steel silk thread or other sealing linear material as the cutlery of cutting crop, during grain header work, the cutting of steel silk thread can be along ground running, thereby the stubble that cuts of realizing crop is zero, satisfy the harvesting technological requirement, reduce Crop damage, improve the crop harvesting rate.

Technical scheme provided by the invention is as follows: comprise frame, front-wheel, trailing wheel, electromotor or internal combustion engine, driving pulley, driven pulley, active line wheel, line of cut wheel and line of cut, it is characterized in that: frame is whole to be the triangle body structure, upper plane and the ground of frame are in a certain angle, and 90 degree are spent, are less than or equal to its angle greater than 0.Electromotor or internal combustion engine connect firmly on frame, and its output shaft is perpendicular to the upper plane of frame triangle body; Transmission arrangements is on the inclined-plane of frame, and driving pulley and driven pulley form the speedup running part; The line of cut wheel is arranged in the front end of reaping machine and initiatively line wheel and tensioned thread are taken turns the running part that forms cutting power; Line of cut is wrapped on active line wheel, line of cut wheel and the tensioned thread wheel; The wheel shaft of front-wheel is fixed on the support, and be fixedly connected on frame with the screw rod on the support and nut, change the position of front-wheel wheel shaft by threaded adjusting, thereby change frame front end and ground distance, also change the position of line of cut wheel, realized the adjustment of grain header ground gap.

Good effect of the present invention is: use this grain header can realize that the stubble that cuts of crop is zero, when the crops such as harvesting leek, satisfy the harvesting technological requirement, reduce Crop damage, improve the crop harvesting rate.The present invention is equally applicable to the harvesting of other various crop.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is that front-wheel ground gap is adjusted structural representation.

Embodiment

See Fig. 1-3, frame 9 integral body are the triangle body structure, and plane and ground are in a certain angle on the frame 9, and 90 degree are spent, are less than or equal to its angle greater than 0; Front-wheel 2 and trailing wheel 10 are equipped with in the bottom of frame 9.Electromotor or internal combustion engine 7 connect firmly on frame 9, and the output shaft of electromotor or engine 7 connects firmly driving pulley 8 perpendicular to the upper plane of frame 9 on the output shaft.Transmission arrangements is on the inclined-plane of frame, and driving pulley 8 is in transmission connection by band with driven pulley 6 and forms the speedup running part; Driven pulley 6 and line initiatively take turns 5 coaxial be an integral body.Initiatively 5, two line of cut wheels 1 of line wheel and tensioned thread wheel 4 all are positioned on the upper plane of frame; Two lines of cut are taken turns 1 and are arranged in the front end of reaping machine and the running part of active line wheel 5 and tensioned thread wheel 4 composition cutting powers; Line of cut 11 is wrapped on active line wheel 5, the line of cut wheel 1 and by tensioned thread wheel 4 and realizes the tightnesses adjusting.

The requirement of cutting stubble realizes by the locus of the wheel shaft 14 of adjustment front-wheel 2, as shown in Figure 3: the wheel shaft 14 of front-wheel is fixed on the support 13, and be fixedly connected on frame 9 with the screw rod 3 on the support and nut 12, change the locus of front-wheel wheel shaft 14 by threaded adjusting, thereby change frame front end and ground distance, realize the adjustment of harvesting machine cut stubble.

Operation principle: as shown in Figure 1 and Figure 2, during work, power is by 7 outputs of electromotor or engine, drives initiatively by driving-belt that line wheel 5 rotates, and initiatively line wheel 5 forms a sealing transmission by line of cut 11 and tensioned thread wheel 4 and line of cut wheel 1; When grain header travelled forward, with certain speed motion, the cutting speed of line of cut 11 was travel forward synthetic with the line of cut speed of service of grain header to line of cut 11 under driving force drives; When touching crop, realizes line of cut 11 cutting to crop.

Claims

One kind to cut stubble be zero Chinese leek reaping machine, comprise frame, front-wheel, trailing wheel, electromotor or internal combustion engine, driving pulley, driven pulley, active line wheel, line of cut wheel and line of cut, it is characterized in that: frame is whole to be the triangle body structure, plane and ground are in a certain angle on the frame, and 90 degree are spent, are less than or equal to its angle greater than 0; Electromotor or internal combustion engine connect firmly on frame, and its output shaft is perpendicular to the upper plane of frame triangle body; Transmission arrangements is on the inclined-plane of frame, and driving pulley and driven pulley form the speedup running part; The line of cut wheel is arranged in the front end of reaping machine and initiatively line wheel and tensioned thread are taken turns the running part that forms cutting power; Line of cut is wrapped on active line wheel, line of cut wheel and the tensioned thread wheel.
