The cutting table is composed of a fixed upper cutter blade and a lower cutter blade which moves in reciprocating mode. The harvester has the advantages of simple driving structure, less power consumption, reliable working and easy operation, and especially has the advantages of small size, light weight and strong maneuverability, so the harvester can be used and popularized in mountain areas and closed countries.
Description
The utility model relates to the small harvester of a kind of mountain area, hilly country use.It is applicable to the harvesting of wheat, paddy rice and other crops.
Existing harvester for both rice and wheat can be divided into horizontal, vertical and the disk swinging.Most of grain headers all are that wide swath, high-power, self-propelled, volume are big, Heavy Weight, drive mechanism are very complicated.This class grain header can only adapt to the vast northern getting wheat of China's field soil, and the southern harvester for rice wheat that incompatibility China field soil is narrow, soil property is soft.Market also has a kind of grain header of imitated Japan in addition, though its volume is less, weight is light, structure is more succinct, also can adapt to southern little field piece operation, but price is very expensive, and vast farmers can't bear, and therefore also is difficult to promote the use of.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of simple in structure, volume is little, in light weight, power consumption is little, reliable operation, processing ease, easy to maintenance, mobility strong can be adapted to the small harvester that little field piece, the softer field of soil piece use.
The purpose of this utility model is to reach by following measure: this small harvester is made up of compact internal combustion engine, clutch, decelerator, worm gear reducer, running gear, toggle, cutting bed, nearside divider and left and right conveying plant.Wherein the output shaft of internal combustion engine joins with input shaft of speed reducer behind clutch.The output shaft of decelerator joins with the worm screw input of worm gear reducer again, and the other end of worm screw joins as the crank of output and toggle.The connecting rod of toggle joins with the bottom knife of cutting bed again.It is affixed that worm and wormwheel subtracts the power transmission shaft of vertical worm gear in the device and running gear.Horizontal worm gear in the worm gear reducer and its vertical output shaft are affixed, and are fixed with output chain gear on this vertical output shaft.This output chain gear joins by the input sprocket on chain and the right conveying plant power shaft again.On the power shaft of right conveying plant, also be fixed with simultaneously output gear.This gear again with left conveying plant on the input gears engaged.
Cutting bed in the utility model technical solution is made up of the removable upper and lower blade that is sharp-tooth shaped.Wherein cutter is fixed, and bottom knife drives reciprocating by the connecting rod of toggle.And are furnished with 4～6 stage clips that are used for adjusting gap between upper and lower blade.
Worm gear reducer in the utility model technical solution is made up of the worm gear of a worm screw, a horizontal positioned and the worm gear of a vertical placement.The end of two worm gears and worm screw wherein is respectively as three of this worm gear reducer different outputs.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is drive mechanism figure of the present utility model.
The utility model is described in further detail below in conjunction with embodiment: this small harvester is the formation by compact internal combustion engine (1), clutch (2), decelerator (3), worm gear reducer (4), running gear (6), toggle (11), cutting bed (14), nearside divider (15), left conveying plant (16) and right conveying plant (12).The output shaft of internal combustion engine in the middle of this (1) links to each other with the power shaft of decelerator (3) behind clutch (2).The output shaft of decelerator (3) joins with the input of the worm screw (5) of worm gear reducer (4) again.And the other end of worm screw (5) joins as the crank of output and toggle (11).The connecting rod of toggle (11) again with cutting bed (14) on bottom knife (18) join.Be equipped with on the cutting bed (14) and be sharp-tooth shaped and removable cutter (17) and bottom knife (18).Wherein cutter (17) is fixing, and bottom knife (18) drives reciprocating by the connecting rod of toggle (11).Simultaneously are being furnished with 4～6 stage clips (19) that are used for adjusting the gap between the upper and lower blade (17,18) on the cutting bed (14).Two mutually perpendicular worm gears are housed in worm gear reducer (4), and wherein vertical worm gear (7) is affixed with the power transmission shaft of running gear (6).And horizontal worm gear (8) is affixed with the vertical output shaft of worm gear reducer (4), and is fixed with output chain gear (9) on this vertical output shaft.This output chain gear (9) joins by the input sprocket (21) on the power shaft of chain (10) and right conveying plant (12) again.On the power shaft of right conveying plant (12), also be fixed with simultaneously output gear (22).This output gear (22) again with the engagement of the input gear (20) of left conveying plant.On right conveying plant (12) and left conveying plant (16), also be separately installed with two belt conveyors (13) that have moving tooth parallel to each other.And whole nearside divider (15) is mounted in the front end of grain header.
When the utility model was worked, the power of internal combustion engine imported the input that worm and wormwheel subtracts device into through clutch, decelerator, and power spreads out of from three outputs that worm and wormwheel subtracts device afterwards.Wherein the worm screw output is passed to bottom knife with power through the crank linkage, makes bottom knife do the commute motion, so cutting bed just can cut wheat.Vertical worm gear output is passed to power the power transmission shaft of running gear again, and whole grain header is walked forward.Horizontal worm gear output is passed to right-hand member with power through sprocket wheel, chain again and is sent device, makes right conveyor running.The output gear of right conveying plant is passed to power left conveying plant again, and left conveying plant is also got into smooth.So each parts of whole grain header are all started working.As long as grain header is walked forward, cutting bed just cuts off the wheat of grain header front, again under the effect of the belt conveyor of left and right conveying plant, divided two-way to enter delivery outlet by the straw of the band fringe that cut off, become 30 ° of angles fitly to be placed upside down on the ground after having cut at last.
The utility model has following features compared to existing technology: complete machine structure is simple, driving-chain is very succinct, The little processing ease of power consumption, little, in light weight, the mobility strong of reliable operation, especially volume are highly suitable for The rice wheat harvesting of little field, the softer field of soil.
