Abstract

The utility model belongs to the field of agricultural machines. The manual harvester comprises a traveling wheel without teeth, wherein, one end of the traveling wheel shaft is fixed with a big sprocket. The other end of the traveling wheel shaft is fixed with a big bevel gear which drives a small bevel gear, and the small bevel gear drives the other shaft to rotate. The rotation of the shaft drives a zigzag form circular knife. The circumference of the zigzag form circular knife is fixed on the shaft to rotate, and the zigzag form circular knife is clamped by an upper and a lower clamping plates. Due to the functions of a ridge divider and of a bottom knife rod, ridge growing crops are harvested. The harvester is one of optimum harvesters based on households at present.

Description

Manual harvester

The utility model belongs to agricultural mechanical field, is specially adapted to the harvesting of ridge kind crop.

Present agricultural grain header has large-scale combine, small-sized hand-held grain header or the like, and kind and version are various, and these grain headers all have its advantage and the scope of application, are adopted by peasants widely.But, the fixed blade of these grain headers and motion blade all are serrated blade, and motion is to move back and forth between the blade, so when the kind crop of harvesting ridge, blade is not operated at full capacity, the position long-term work that blade has, and do not work for a long time in the position that has, this is because ridge kind crop has crop in ridge portion, does not have crop to cause in ditch portion.In addition, be to move back and forth between fixed blade and the motion blade, move back and forth member and damage easily than the member of garden Zhou Yundong, and institute consume power also more, this is owing to reciprocating motion has the dead point to cause.In order to overcome existing harvesting, above-mentioned two place's weak points, will redesign a kind of grain header that adapts to ridge kind crop.

The purpose of this utility model will design the basic evenly work of a kind of blade exactly, and the motion of blade is garden Zhou Yundong, reduces the damage of blade and member, reduces power consumption, the hand reaper of increasing work efficiency.

Designer of the present utility model has conceived a kind of hand reaper.Hand reaper adopts the circular saw machine teeth cutter blade and the fixing no profile of tooth bed plate bar of an activity, utilizes the relative motion of blade and knife bar to reach the purpose of harvesting crop, and gathers in the splendid hand reaper of ridge kind crop effect.Concrete structure as depicted in figs. 1 and 2.Fig. 1 is the front view that hand reaper has broken section, and Fig. 2 is the vertical view of hand reaper.From Fig. 1 and Fig. 2 as can be seen, hand reaper is by a toothed travelling wheel (2), fix a hinge wheel (3) at an end of traveling wheel shaft (4), hinge wheel drives minor sprocket (6) by chain (5), because minor sprocket is fixed on the axle (7), the other end at axle is fixed with large bevel gear (8), large bevel gear drives cone pinion (9), cone pinion drives axle (10) and rotates, axle (10) rotation drive is clamped by last lower plate (11), and the saw shape garden disc blades (12) that is fixed in garden week on the axle (10) is rotated.Because hand reaper has branch ridge device (14) and bed plate bar (13) to act on, just in time a ridge culture thing to be sent between bed plate bar and the garden disc blades along the direction of arrow, the rotation of garden disc blades is so just crop harvesting.Owing to divide the effect of the side rod of ridge device (14), the good crop of harvesting is pushed to a direction topple over again, the receipts of being convenient to crop are adopted.These parts all are to be fixed on the fuselage (1) with bolt or welding manner, and afterbody has handgrip, and handgrip is to be used for pushing away to the people holding up use.So when a very important person buttressed handgrip and carries out forward, harvesting just can be worked.No matter the people carry out soon with slowly, grain header can both have the harvesting function.This is owing to all be the cause of speedup in the harvesting motion process.

The utility model is compared with other grain header, and following advantage is arranged: (one) does not need electricity or engine class power.(2) be suitable for the harvesting of ridge kind crop, blade work is even, uses fully.(3) because blade is garden Zhou Yundong, not fragile parts.(4) low price is applicable to that present single household uses.

Embodiment: fuselage (1) is to be welded with angle steel, channel-section steel.Umbrella tooth cover (15), chain wheel cover (17), traveling wheel cover (16) all adopt the mode of screw attachment to be fixed on the fuselage (1).Axle (4) is fixed on the fuselage (1) by the screw attachment mode with bearing block with axle (7).Branch ridge device (14) is done triangularity, and the afterbody of bed plate bar (13) is made the garden arc, and tilts upward, and side rod in the branch ridge device (14) and bed plate bar (13) are by dress up herringbone (seeing) in vertical view 2.This way purpose is convenient to crop and is concentrated and to enter, and good crop is put upside down in order to make harvesting.This hand reaper per hour can gather in three mu of alley grow wheats, and harvesting efficiency is high, and the harvesting cost is low, so be one of best grain header of present single household.

Claims

1, by fuselage, axle, bearing, sprocket wheel, part such as bevel gear and cover, the hand reaper that parts are formed, it is characterized in that: fix a hinge wheel (3) at an end of traveling wheel shaft (4) by a toothed travelling wheel (2), hinge wheel is driven the minor sprocket (6) that is fixed on the axle (7) by chain (5), the other end at axle is fixed with large bevel gear (8), large bevel gear drives cone pinion (9), cone pinion drives axle (10) and rotates, axle (10) rotation drive is clamped by last lower plate (11), and be fixed on the saw shape garden disc blades (12) of axle on (10) garden week and rotate, branch ridge device (14) and bed plate bar (13) are arranged again.

2, hand reaper according to claim 1 is characterized in that: branch ridge device (14) is a triangle, and the afterbody of bed plate bar (13) is made the garden arc, and tilts upward.
