Abstract

The utility model relates to a man-power harvester, which belongs to an agricultural harvesting machine. The harvesting cutting tool technique of the man-power harvester adopts the draw cut mode, the man-power harvester is driven by man-power treading, and the man power can be transferred to the draw cut knives through a sprocket driving system so as to achieve the good harvesting effect. The man-power harvester can operate in paddy fields and upland fields, and meanwhile, can also adapt to operating in scattered small fields. The man-power harvester has the advantages of light weight and easy transportation.

Description

Man-power harvester

Hand reaper, a kind of agricultural harvesting machinery.

In the existing grain header, no matter adopt manpower or other power, generally gather in cutter and all cut off crops with cutting mode.The utility model has improved traditional cutting technique, and the harvesting cutter gathers in the sawing mode, even the foot-operated grain header that drives of manpower also can reach good result.

The utility model complete skill scheme is as follows: hand reaper is divided into three parts, a walking part, two speed change running parts, three harvesting cutter parts.Running gear is by frame, the direction tail wheel, and road wheel, the device of riding is formed jointly.The speed change running part is made up of chain sprocket and conical gear.People's the foot-operated strength of riding passes to the harvesting cutter by conical gear at last.The walking desin speed is 0.2 to 0.4 meter of a per second.Running gear and speed change running part can be processed in manufacturing tricycle factory.The utility model core technology is a harvesting cutter part.Be illustrated below in conjunction with accompanying drawing.Harvesting cutter part is by Fig. 1, and Fig. 2 and Fig. 3 represent, by driving shaft 1, and driven shaft 8, chain saw cutter 5, chain jamming sawing groove 4 is formed.Conical gear 2 is arranged, drive sprocket 3 on the driving shaft 1.Driven sprocket 7 is arranged on the driven shaft 8.Chain saw cutter 5, be on bicycle chain (perhaps other standard component chains) to adorn some triangle sawtooth angle of throat sheets (parts 6 among Fig. 1) shown in Figure 3 made.Fig. 2 intuitively expresses chain jamming sawing groove 4, processing one row's sharp sword straight-tooth on the groove, and whole component processing well later on can be as rigging position among Fig. 1.When the grain header startup, when driving shaft 1 was rotated counterclockwise, straight-tooth angle of throat and chain saw cutter were done relative motion on the chain jamming sawing groove, and at this moment, the crops cane that enters tooth and cutter relative motion space is cut off by sawing.The compound just formation of relative motion and grain header walking movement harvesting operation between serrated knife.

Hand reaper of the present utility model utilization sawing technology, gather in laborsaving, the cuttting cleaning rate height.About 40 kilograms of complete machine weight, two people can lift, and are easy to carrying.The harvesting flexible movements, not only suitable dry land but also can be, also suitable simultaneously scattered fritter field operation at paddy-field-working.

Embodiment: 700 millimeters of driving shaft 1 length, 20 millimeters of external diameters, the steel that internal diameter is 16 millimeters are made.Conical gear 2, the number of teeth 19, interaxial angle 90 degree, short straight-tooth, 50 millimeters of pitch diameters by GB production, are contained on the driving shaft 1 with key or other coupling methods.Drive sprocket 3,60 millimeters of diameters, thick 3 millimeters, the number of teeth 14 is welded on driving shaft 1.Chain jamming sawing groove, the punch process one-shot forming, 1080 millimeters of the harvesting widths of groove, the chain jamming size of groove is looked chain and the die sinking formulation, 160 millimeters of the chain jamming degree of depth of groove are made with thick 2 millimeters steel plates, and the supporting base of chain jamming sawing groove is respectively opened a hole, 16 millimeters of diameters are installed master, driven shaft so that cooperate.Chain uses bicycle or other standard components.The sawing cutter is made right angled triangle, 70 millimeters of right angle length of sides, and 55 millimeters of another right angle length of sides are processed two and chain part the apertures that cooperate are installed, and diameter is generally 3.5 millimeters, or decides on chain, and hypotenuse is processed into the zigzag keen edge.Driven sprocket 7 is identical with drive sprocket.Driven shaft is identical with driving shaft.This hand reaper all uses ferrous materials.Solid shafting with 8 millimeters of bearing standard spare and diameters is enclosed within on the master and slave moving axis at last, and above each part is assemblied on the grain header body, and riding when manpower steps, and grain header just gathers in.

Claims

Hand reaper, particularly a kind of by walking, speed change transmission and harvesting cutter three parts form by manpower foot-driven grain header, it is characterized in that: harvesting cutter part is by driving shaft, conical gear, drive sprocket, chain jamming sawing groove, chain saw cutter, driven sprocket, driven shaft is formed, and the sawing blade is that hypotenuse is the zigzag keen edge.
