Description
Technical field
The present invention relates to a kind of claw folding sisal hemp grain header.
Background technology
Sisal hemp is a kind of perennial tropical hard leaf fibre crop, originates in Mexico, and now mainly planting in Africa, Latin America, Asia and other places, is the hard fibre that in the world today, consumption is maximum, widest in area.Sisal fiber is strong but pliable in texture, wear-resisting, Salt And Alkali Tolerance, is widely used in the industries such as transport, fishery, oil, metallurgy, has important economic worth.Sisal hemp processed goods mainly comprises sisal fiber, sisal hemp sliver, sisal hemp carpet, polishing wheel for sisal hemp, Steel cord, saponin, sisal hemp wallpaper and other sisal hemp goods.In addition sisal hemp is also for its feeding material in agricultural production, and Crop fertilizer, and sisal dregs is also for producing the products such as alcohol, oxalic acid, pectin.Visible, the purposes of sisal hemp widely.
Nowadays, the treatment and processing technique comparative maturity of sisal hemp.But from ground, gather in the crops this work of sisal leaves still by peasant is manual, blade is cut down, all there is no the application of mechanical harvest sisal hemp all over the world.The results results technology that other crudefiber crops are ripe relatively in this field, can only say and also be in development.
Summary of the invention
The object of the invention is to for domestic and international also immature sisal hemp results technology, a kind of claw folding sisal hemp grain header be provided, it is simple and reasonable, installation and easy to maintenance, greatly can improve efficiency of crop.
To achieve these goals, the design of the claw folding sisal hemp grain header designed by the present invention is as follows:
This claw folding sisal hemp grain header comprises two parts: cutting part and control section.Cutting part, cleverly in conjunction with four-bar mechanism simple principle, realizes a hydraulic stem with two symmetrical four-bar mechanisms and controls two push rods and promote two work pawls and complete opening and closing movement.Just form an orthohexagonal annular after two work pawls close close and have the closed area of cutting power, the cutting tip at the uniform velocity feeding from the bottom up of this annular, cuts away the numb leaf in numb strain in process upwards.Control section reasonably have selected the sequentially-operating loop in hydraulic control, folding and the elevating movement of work pawl is controlled respectively by the hydraulic cylinder of two interlocks, with a hydraulic valve and four travel switches, only the button need pressed on handle just can realize a working cycles of work pawl.
According to foregoing invention design, the present invention adopts following technical scheme:
A kind of claw folding sisal hemp grain header, comprises two work pawls, support bar, hinges, movable push bar, hydraulic stem, wheel, handlebar, headstock, the first hydraulic cylinder and the second hydraulic cylinder, guide rod and vehicle frames; One end of described two work pawls is by the symmetrical two ends being arranged on movable push bar of hinges, the outside of two work pawls is connected with the second hydraulic cylinder respectively by support bar, one end of support bar can be moved along guide rod, the middle part of described movable push bar connects the first hydraulic cylinder by hydraulic stem, described headstock is arranged in the go-cart that is made up of wheel, handlebar and vehicle frame, and described first hydraulic cylinder is connected with headstock with the second hydraulic cylinder.
Described work pawl comprises dish type saw blade, saw blade fixed disk, bevel gear, power input shaft, some dish type saw blades are fixed on corresponding saw blade fixed disk, and saw blade fixed disk is connected by key with bevel gear, and some bevel gears are intermeshing to be arranged in work pawl, being positioned at middle bevel gear is driving wheel, be connected by key with power input shaft, the bevel gear being positioned at both sides is driven pulley, and power input shaft connects external motor.
Compared with prior art, the present invention has following advantage:
Two work pawls of the present invention can form the harvesting in a circumference orientation, can avoid to a great extent leakage cutting, and can by the driving of hydraulic system automatic open-close, substantially increase harvesting efficiency thus instead of hand harvest.

Embodiment
Details are as follows by reference to the accompanying drawings for the preferred embodiments of the present invention:
As shown in Figures 1 to 4, a kind of claw folding sisal hemp grain header, comprises two work pawls, support bar 5, hinges 6, movable push bar 7, hydraulic stem 8, wheel 9, handlebar 10, headstock 11, first hydraulic cylinder 12 and the second hydraulic cylinder 13, guide rod 14 and vehicle frames 15; One end of described two work pawls is by the symmetrical two ends being arranged on movable push bar 7 of hinges 6, the outside of two work pawls is connected with the second hydraulic cylinder 13 respectively by support bar 5, one end of support bar 5 can be moved along guide rod 14, the middle part of described movable push bar 7 connects the first hydraulic cylinder 12 by hydraulic stem 8, described headstock 11 is arranged in the go-cart that is made up of wheel 9, handlebar 10 and vehicle frame 15, and described first hydraulic cylinder 12 is connected with headstock 11 with the second hydraulic cylinder 13.
As shown in Figure 3, described work pawl comprises dish type saw blade 1, saw blade fixed disk 2, and bevel gear 3, power input shaft 4, three dish type saw blades 1 are fixed on corresponding saw blade fixed disk 2, and the angle between three dish type saw blades 1 is 120 degree.Saw blade fixed disk 2 is connected by key with bevel gear 3, five bevel gears 3 are intermeshing to be arranged in work pawl, and being positioned at middle bevel gear 3 is driving wheel, is connected by key with power input shaft 4, the bevel gear 3 being positioned at both sides is driven pulley, and power input shaft 4 connects external motor.
The course of work of the present invention is as follows:
During harvesting sisal hemp, the harvesting part of dolly is allowed to be wrapped by the stem of sisal hemp, then press and set about the button on 10, now hydraulic system is started working, the hydraulic oil of the first hydraulic cylinder 12 li promotes hydraulic stem 8 and moves backward, movable push bar 7 to after-contraction, at support bar 5, make two pawls that work close up into a circle under the acting in conjunction of hydraulic stem 8, the stem of sisal hemp is embraced.External motor starts, power from power power shaft 4 inputs, dish type saw blade 1 is driven to rotate through bevel gear 3, then the second hydraulic cylinder 13 works, by work pawl and the first hydraulic cylinder 12 together upwardly, while the first hydraulic cylinder 12 and work pawl move upward along guide rod 14, six dish type saw blades 1 start the leaf cutting sisal hemp, complete harvesting action.And then press assistant the button on 10, motor stalls, the second hydraulic cylinder 13 starts backhaul to elemental height, movable push bar 7 is driven to launch by the first hydraulic cylinder 12 driven forward hydraulic stem 8 again, with under support bar 5 acting in conjunction, work pawl opens, and dolly exits and gathers in next time again.
