Abstract
The utility model provides a rice harvester, comprising a hand cart on which wheels and a cart bracket are disposed. The utility model is characterized in that the hand cart is provided with a harvest device composed of a hood casing, harvest cutters and a driving element, wherein the harvest cutters are mounted on the lower portion of the hood casing and the driving element drives the harvest cutters to rotate. By the rotation of the wheels of the hand cart, the utility model is capable of realizing the rice harvest, and thereby no energy resource is consumed but human labor. Owing to the advantages of simple structure, low manufacture cost, light weight, convenience and flexibility, the superiority of the utility model in particular is displayed in irregular and small-sized fields, such as sloping fields, hilly land, terrace and the like. Therefore, the utility model is a relative ideal ultra-small and convenient agricultural harvester.
Description
The utility model relates to a kind of grain header, and especially a kind of manual type standing grain rice grain header belongs to agricultural machinery.
Along with improving constantly of science and technology development and agricultural mechanization degree, people have constantly released various big, medium-sized grain header or combine and miniature diesel or Electric harvester or the like, but only being adapted at of having in these grain headers used in flat area or the large-area smooth rice field, in hillside fields or rice field, mountain area, then can't use, though what have can use in hillside fields or rice field, mountain area, but consume diesel oil or electric power, still can not apply in outlying mountain area or areas without electricity, therefore, be necessary development or exploitation can be in the hillside fields or the mountain area use, do not consume the small harvester of any energy simultaneously again.
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of manual type standing grain rice grain header that does not consume any energy is provided.
The utility model is realized by following technical proposal: it comprises the wheelbarrow which is provided with wheel and vehicle frame, it is characterized in that being provided with on wheelbarrow the reaping apparatus that drive disk assembly constituted by case, the cutter of being located at the case bottom, the rotation of driving cutter.One side of described case is an arc surface, and the toppling direction by after this arc surface arrangement, the cutting of control standing grain rice is provided with groove in the bottom of this case, is used to place cutter.Described cutter are a circular shear blade, by blade shaft, a pair of umbrella tooth that is fixed on the center and the power transmission shaft that is fixed on the case cutter are placed in the groove of case bottom, are provided with sawtooth at the edge of cutter, are used for efficiently cutting the standing grain rice.Described drive disk assembly is made of the chain of being located at one group of drive sprocket on the wheel hub, being located at another group drive sprocket on the case power transmission shaft and connecting them, wherein each group drive sprocket is made of fixed chain wheels and movable sprocket wheel, so that rotating band movable sprocket group, power transmission shaft and umbrella tooth by trolley wheel rotate, thereby drive the cutter rotation and the harvesting of realization standing grain rice.
The utility model compared with prior art has following advantage and effect: because reaping apparatus is arranged on the wheelbarrow, and the multistage transmission by transmission component, make this grain header can realize the harvesting of standing grain rice by the rotation of trolley wheel, therefore except that manpower, do not consume any energy, because simple in structure, cost is low, in light weight, convenient, flexible, especially the superior function that in the field of irregular small sizes such as hillside fields, mountain region, terraced fields, more can show it, therefore, be a kind of comparatively desirable small agricultural machinery.
Fig. 1 is the front view of the utility model;
Fig. 2 is the vertical view of the utility model.
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure, 1 is the wheelbarrow vehicle frame, 2 is trolley wheel, 3 is wheel hub, 4 is case, the one side is provided with arc surface 41, be used for arrangement, the toppling direction of control standing grain rice, its underpart is provided with groove 42, be used to put cutter, 5 is cutter, is a circular shear blade, and its edge is provided with sawtooth 51, the middle part is fixed with blade shaft 52, the upper end of axle 52 is fixed with umbrella tooth 61, and another umbrella tooth 62 is meshed with 61, and umbrella tooth 62 is fixed on the power transmission shaft 7, the other end of power transmission shaft 7 is fixed on the case 4 by rolling bearing, when power transmission shaft 7 rotates, can make the umbrella tooth 61 that is meshed, 62 rotate thereupon, rotate thereby drive cutter 5, realize the harvesting of standing grain rice, 8 for being arranged at one group of sprocket wheel on the wheel shaft 3, and wherein, sprocket wheel 81 is unidirectional fast pulley, promptly closely cooperate with wheel shaft 3, so that the forward rotation with wheel shaft 3 is rotated, when wheel shaft 3 backward rotation, sprocket wheel 81 does not rotate, sprocket wheel 82 and 82 is made as one, be movable wheel, they and wheel shaft 3 are slidingly matched, and the diameter of sprocket wheel 82 is less than the diameter of sprocket wheel 83,9 for being located at another group sprocket wheel on the power transmission shaft 7, wherein, sprocket wheel 91 and 92 is made as one, and is movable wheel, they and power transmission shaft 7 are slidingly matched, the diameter of sprocket wheel 91 is less than the diameter of sprocket wheel 92, and sprocket wheel 93 is a fast pulley, and it and power transmission shaft 7 closely cooperate, being used to drive power transmission shaft 7 rotates, 11 for connecting sprocket wheel 81,91 chain, 12 for connecting sprocket wheel 82,92 chain, 13 for connecting sprocket wheel 83,93 chain.When the promotion wheelbarrow moves forward, wheel 2 and wheel shaft 3 forward rotation, the sprocket wheel 81 on the wheel shaft 3 also rotates thereupon, driving sprocket wheel 91,92 by chain 11 rotates, drive sprocket wheel 82,83 by chain 12 again and rotate, drive sprocket wheel 93 by chain 13 again and rotate, power transmission shaft 7 rotates with sprocket wheel 93, driving cutter 5 by umbrella tooth 61,62 rotates, otherwise when pulling back wheelbarrow, sprocket wheel 81 does not rotate, thereby a whole set of cutter sweep is not worked, both laborsaving, avoid occurring security incident again.
Claims (5)
