Description

A kind of light-duty rice and wheat harvester

The utility model relates to a kind of agricultural machinery, particularly a kind of hand steered self-propelled light-duty multifunctional rice and wheat harvester.

CN2260445Y discloses a kind of " hand-held swather ", it is provided with engine above frame, there is handrail at the frame rear portion, the walking main shaft two ends of frame bottom are provided with road wheel, be equipped with the chain drive pair between the main-gear box of main shaft and upper rack, frame front is equipped with the cutting and putting down machine structure, on the cutting and putting down machine structure, be provided with the careless plate of branch and dial careless steel wire etc., on handrail, be provided with throttle, clutch, between clutch and main-gear box, clutch cable is housed, it is characterized in that: the engine on the frame is 4.4 horsepowers a diesel engine, cover is connected with the belt transmission pair between main-gear box and the front gear box, and the slip clutch that links to each other with the clutch backguy is installed among the belt pulley on the power shaft outside the main-gear box.The swather of this structure is because the engine that adopts is 4.4 horsepowers a diesel engine, and volume is big, and Heavy Weight is not suitable for the hilly country, mountain area; Because the clutch that adopts is a slip clutch, long-time use is easily skidded, and when situation is serious, could use the poor reliability of work after also must changing; And its changement adopts preposition gear-box, complex structure, cost height.

It is a kind of simple in structure that the purpose of this utility model is to provide, and volume is little, and is in light weight, and cost is low, the light-duty rice and wheat harvester that reliability is high.

The utility model is achieved in that a kind of light-duty rice and wheat harvester, and it comprises handrail, frame, engine, gearbox that links to each other through belt pulley with power machine output shaft and the road wheel that links to each other with two output shafts of gearbox respectively and by vertical conveyer belt, cutter, straw-poking star wheel, the ceding of Taiwan that nearside divider is formed, it is characterized in that: described engine is a gasoline engine, and its starting easily, and is in light weight, power output is stable, the reliability height; The output shaft I upper belt pulley of described gearbox links to each other through belt with the belt pulley of the described ceding of Taiwan, be provided with directive wheel therebetween, make the vertical rotation of gearbox pulley realize horizontally rotating of ceding of Taiwan main shaft by the secondary commutation of belt transmission, thereby the reciprocating vertical conveyer belt that carries out cutting work and drive on it of crank driving cutter that drives under it is carried the standing grain strain, this is a kind of easy to manufacture, changement easy to maintenance, that cost is minimum; Sprocket wheel on the output shaft II of described gearbox links to each other with road wheel through chain wheel pair, is rotated by the chain wheel pair ground-engaging wheel.

In order to stop gasoline engine because of the too much blockage phenomenon of working environment dust, improve its job stability, can connect a flexible pipe at the carburetor air inlet place of gasoline engine, no longer head-on relative to change the air intake direction of carburetor with dust, the inlet of minimizing dust.

In order further to reduce cost, can adopt such gearbox, in its casing power shaft is arranged, two output shaft I, II, declutch shift shaft and on the cylindrical cam clutch yoke, wherein the cabinet end of stretching out of power shaft has the belt pulley that links to each other through belt with the belt pulley of output shaft of gasoline engine, the other end of power shaft has gear Z1; Have the gear Z2 engagement of shaft coupling pawl on gear Z1 and the output shaft I, the cabinet end of stretching out of output shaft I has the belt pulley that links to each other through belt with ceding of Taiwan belt pulley, and its corresponding end has gear Z3; Output shaft II stretches out cabinet end sprocket wheel, the gear Z4 of the overhead cover of output shaft II and the engagement of the gear Z3 on the output shaft I, and the side of gear Z4 has clutch pawl and supporting cylindrical cam clutch yoke; Declutch shift shaft links to each other with clutch lever on the handrail.

Adopt the rice and wheat harvester of this structure, since rational in infrastructure, do not need big horsepower, only 2 horsepowers gasoline engine can drive complete machine work, thereby has reduced machine volume, has alleviated the weight of complete machine, and every is heavy 60 kilograms, easy operating; Establish a flexible pipe at the air inlet of gasoline engine carburetor, dust is difficult for entering the carburetor blockage phenomenon, has improved the job stability and the operating efficiency of gasoline engine, per hour gathers in about 3 mu; Its changement is only by simple directive wheel, and the commutation of the vertical rotation of belt transmission adjutant's gearbox pulley has reduced cost to realize horizontally rotating of harvesting mechanism main shaft; And the utility model adopted a kind of novel gearbox, reduces cost to greatest extent.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1: the structural representation of the utility model embodiment.

Referring to accompanying drawing as can be known: a kind of light-duty rice and wheat harvester, it comprises handrail 25, frame 6, engine 4, the gearbox 26 that links to each other through
