Abstract
The utility model relates to a harvester which uses manual work as dynamic force, which is composed of a gear box, a wheat teasing strip, a slide plate, a cutter frame and a traveling wheel. The utility model uses shearing action like a hair clipper to harvest wheat, rice, pasture grass, etc. A manual harvester has the advantages of simple structure, convenient operation, continuous operation, time saving, labor saving and high efficiency, which combines cutting, collecting, placing, pushing, etc., functions into integration. The utility model is suitable for technical requirements for different human body abilities, different crops, different areas and different topographies, being a necessary manual harvester for farmhouses.
Description
The utility model belongs to a kind of utilization manually as power, carries out the machinery of getting wheat, paddy rice, herbage or other crops.
At present, people are engaged in getting wheat, paddy rice and herbage, and often the main tool of using remains the reaping hook that forefathers hand down.When using reaping hook to carry out work, bend over to stoop, kick one's legs and wave arm, at the end of the day, soreness of waist and ache in legs.Thereby annual receipts wheat cuts rice farm work, becomes the field work that people inspire awe even from distance.People press for a kind of simple and easy, harvesting machinery easily, so that people are freed from heavy field work.For this reason, people have carried out many examinations of repaying.As the spade formula wheat rice harvester that occurs in recent years, its incision principle is the same with reaping hook, still is cutting.Require its cutting knife close proximity to ground during operation, the resistance of motion is big like this, and the edge of a knife is also easy to wear, cuts the also bad adjusting of height of stubble.Its cutting, folding and unfolding are again intermittent operations, and efficient is lower.
Also have the wheeled harvester for wheat of a kind of hand push, what it adopted is chain, gear and belt transmission, complex structure.Simultaneously it cuts wheat, gathering, stacking, also is to be interrupted operation, and efficient is lower.Add that its specification is single, cost is higher, and its scope of application just has been subjected to limitation.
The purpose of this utility model, it is advanced more, practical more to create a kind of existing some harvesting machineries exactly, can be used for the artificial mechanism of getting wheat, paddy rice, herbage or other crop.
The utility model manual harvester structurally has following technical characterictic:
1, wheel type traveling mechanism and speed-changing gear box are mounted on the frame.
2, power transmission has adopted bent axle and the remote transmission mechanism of steel cable, so not only compact conformation, and reliable in action.
3, shear action is realized do the relative shear campaign by the static knife rack on the relative frame of movable knife rack on the steel cable driving slide plate, replaces traditional cutting action with shear action like this, and is not only laborsaving, and a free adjustment that has realized cutting the stubble height.
4, drawing action in is the rack pinion transmission that drives by driving wire rope, drive dial wheat with on dial that wooden fork realizes.So just will shear and draw in action combines.
5, stacking action is in work is carried out, and by the pulling control handle, will amass the wheat frame by steel cable and overturn that an angle carries out.
The utility model manual harvester, owing to adopt above technical characterictic, compare with existing spade formula harvester and the wheeled harvester for wheat of hand push, not only accomplished simple in structure, easy to operate, and can collect action such as cutting, gathering, stacking and be one, realized working continuously, improved production efficiency.
Accompanying drawing is axle side structure and the operation principle schematic diagram of the utility model manual harvester embodiment.
Axle side structure and operation principle schematic diagram in conjunction with the utility model embodiment further specify as follows:
Operator one hand steered the handle of this machine push rod 5, Yi Bian push hard forward, Yi Bian the direction of adjustment and static knife rack 12 are apart from the distance on ground.So not only can ground-engaging wheel 18 rotate, drive this artificial grain header and advance, simultaneously controlled direction of advance and cut the height of stubble also.
The operator is simultaneously with the crank 2 on another hand rotation gearbox 3, and by the gear drive and the speed change of gearbox inside, the bent axle 4 that drives on the gearbox rotates.The two ends of the two ends of bent axle 4 and same driving wire rope are linked together respectively.In the middle of the driving wire rope by two be separately fixed at two on the bearing 19 pulley 20 and the column at slide plate 6 middle parts be fixed together.Unclamp the bolt of column upper center, can adjust the relative position of driving wire rope and slide plate 6.Four screws of slide plate 6 usefulness are fixed together with guide pillar 8 and tooth bar 15, and guide pillar 8 and tooth bar 15 are to be through on two bearing 19 pilot holes that are fixed together with frame.Slide plate 6 is fixed together with the movable knife rack 11 that blade is housed.Rotate the crank 2 on the gearbox 3 like this,, just can drive slide plate 6 and movable knife rack 11,,, do reciprocal shearing motion with respect to the static knife rack 12 that blade is housed along the direction of arrow among the figure by gearbox 3 and driving wire rope.Wheat, paddy rice, herbage or other crop can be cut off.
The reciprocating motion of tooth bar 15 drives ratchet-gear wheel 14 and comes and goes rotation.Ratchet-gear wheel 14 is by can only making the directed ratchet that rotates, and with large dial wheel 17 and fixingly dial wheat with 7 belt pulley, is fixed together, and is enclosed within on the same axis.The round rotation of ratchet-gear wheel 14 can drive large dial wheel 17 and the fixing belt pulley of dialling the wheat band, does directed gap and rotates.Dial wheat like this with the tooth on wooden fork and the large dial wheel 17 dialled on 7, just can be with the wheat that cuts off, clamping mutually, moves to the other end with gap, is placed upside down in then to amass on the wheat frame 13.
The other end of long-pending wheat frame 13 is linked together with thin steel rope and control handle 1.When the wheat on the equivalance wheat frame amassed some, pulling control handle 1 just can make angle of long-pending wheat frame 13 upsets, and the wheat that slices off is deposited into the ground naturally.
In the front of movable knife rack 11 bent plate columns, one and frame should be installed be fixed together, existing certain fastness does not hinder again and dials wheat with 7 and the plate washer that moves of movable knife rack 11.In order to reliability and the safety of protecting this artificial grain header actuator movement.
What deserves to be mentioned is, the utility model manual harvester, the shearing width of its dynamic and static knife rest, the shape of blade and what are can be according to the size of human body ability, the difference of cutting object is made plurality of specifications and shape.The utility model manual harvester so just can adapt to the different characteristic of human body ability, adapts to the different technologies requirement of Different Crop, different regions and landform.
