Description

Shear-type hand harvester

The utility model relates to the manpower corn mowing machine in a kind of agricultural tool.Be used for getting wheat, also can be used for gathering in paddy rice, soybean.

Present hand reaper has domesticly occurred severally, and a kind of is fixedly cutter of V-arrangement, and the V-arrangement cutter is contained on the simple frame, and the people pushes with higher speed forward during work, and by inertia, the V-arrangement cutter cuts the wheat cane.During arrangement works, labour intensity is big like this, and work can not be lasting.Another kind is a horizontal garden dish cutter, and the rotation cutting force of garden dish cutter is from land wheel, with the vee-pulley transmission of a pair of break-in.The cutting force of this structure garden dish cutter can not be big, otherwise land wheel skid be with motionless.

The purpose of this utility model is to want to propose a kind of structure, alleviates the labour intensity of Manpower harvester, and not working power is economical and practical.

The purpose of this utility model is achieved in that the groundwork principle cuts the crop cane by shearing.The hand steered grain header of this scissors is bearing on a pair of road wheel by cutter (moving knife), bottom knife (stationary knife).Shearing is by upper and lower lever transmission.Upper and lower lever is respectively a rigid structure, upper lever is fixed, its front end is a V-arrangement, two tips of V-arrangement are fixed two and are pressed the sword piece, be pressed on the cutter, the fixing column downward vertically of the afterbody of V-arrangement, be pressed in the afterbody of bottom knife simultaneously, following lever is movable, and its front end also is a V-arrangement below upper lever, overlaps with the V-arrangement projection of upper lever, the afterbody of V-arrangement has an axle sleeve, be enclosed within on the column of upper lever V-arrangement afterbody, two tips of V-arrangement fix two vertically downward stir pillar, be inserted in the stirring in the groove of cutter afterbody.Instantly during the lever reciprocally swinging, be hinged support just,, stir cutter and move back and forth with stirring pillar with upper lever V-arrangement afterbody column.The transmission shearing force.On the land axle symmetrical centre place of grain header, adorn one and put paving component and put the shop auxiliary member, below by adorning a micromatic setting.

Micromatic setting is fixed vertically downward an axle sleeve at the symmetrical centre place of land axle, connect one with the garden pin on the axle sleeve and mention bar, and this bar utilizes the fit clearance of garden pin and axle sleeve to reverse slightly in axle sleeve, mentions on the fixed lower blade of bar lower end.The thrust that grain header advances is mentioned bar by upper lever through bottom knife and is passed to land axle.Mentioning that bar reverses slightly is that to aim at the crop minor adjustments in order to gather in convenient.Mentioning on the bar garden column pin hole has a plurality ofly, and the height that cuts stubble can be adjusted in the position that changes pin-and-hole.

This grain header also has one to put paving component, and put the shop auxiliary member, structure is that the left side of grain header is propped up and fixed a vertical rod on the bar, outside cover one pipe box, land axle symmetrical centre place upwards vertically adorns a vertical rod, outside cover one pipe box, on two pipe boxes, fix a framework to the four edges of grain header afterbody indent, have one to put the shop auxiliary member in the centre of framework, it is by on the hinged rocking arm of two parallel transverse serrated rods, the hinged wedge in the lower end on the rocking arm, and the pressured spring that contracts of wedge withstands on the width of cloth bar of land wheel, two band tooth cross bars and wedge and spring all pass through support bar, are fixed on the land axle.

With bottom knife, the cutter three is linked together cutter and leaves sufficiently long dead slot at the bolt place pressure sword piece of this grain header by bolt, and two pins that do not influence the cutter motion are equipped with in the bolt both sides.This two pin is for after tightening at bolt, and the gap of fixing upper and lower blade guarantees that blade moves back and forth.

So far bottom knife is by the bolt of two pressure sword pieces, and the column of upper lever V-arrangement afterbody with linking together of upper lever rigidity, plays the effect of supporting cutting.Entire mechanism is by mentioning firm being hung on the land axle of bar.
