Description
Technical field
The utility model relates to grass harvester tool field, particularly a kind of self-propelled grass harvester.
Background technology
At present, domestic existing more close grass harvester, facility and four-wheel tractor use, and its structure has included hay rake structure, cutting mechanism, profiling force feed grass mechanism, Sokcho mechanism etc.These four planet axis one ends hugging straw articles of hugging grass harvester drive the rotation of rolling of four connecting lever axles in a peach type rail groove, realize the rotation of each root planet axis, this structure is prone to the axial float of connecting lever axle, and the connecting lever axle is de-orbited, and it is unreliable to work.In addition, the reciprocating motion of these cutter moving knife is by the distortion push-and-pull moving knife bar of the spring flat steel of riveting on the moving knife bar, and spring flat steel is driven by swing arm.Constant in order to guarantee the gap between stationary knife and the moving knife, the long more deflection of spring flat steel is more little, angle between moving knife bar and the swing arm is also just more little, and spring flat steel can not fracture because of tired yet, and the gap between moving knife and the stationary knife changes also just more little, but spring flat steel is long more, the just easy more grass retaining that will slice off is in the spring flat steel front, because congested, the grass of back is difficult for entering cutter, easily produce to leak and cut or grass is broken, make that to cut stubble uneven.Its imitative type force feed grass is to the less grass that easily twines of roller diameter, and the profiling top roll does not have grass guard, and grass easily returns with roller strap, is wrapped on the roller.Horn mouth formula Sokcho mechanism promotes in a flash at facility, and when power did not also all disconnect, back horn mouth lower end was easily played straw cord and is wrapped on the pair roller, and functional reliability is poor, haves much room for improvement.
Summary of the invention
The utility model aims to provide a kind of planet axis and drives bracket panel by the connecting lever axle, change the rotation of planet axis self, reliable operation, the gap changes for a short time between cutting moving knife and the stationary knife, is difficult for gathering around grass, straw winding in the cutting process, high efficiency, the facility maneuverability, radius of turn is little, adaptable self-propelled grass harvester.
The technical scheme that realizes the utility model purpose is such: a kind of self-propelled grass harvester, comprise the careless mechanism of branch, hay rake structure, cutting mechanism, profiling grass transmitting machine structure, grass binding strip mechanism, running gear, gear, the careless mechanism of described branch is provided with two groups of prismatic grass dividers in the frame front lower place, above frame front end grass divider, establish left and right regulating arm, a barb stationary knife is respectively established in the regulating arm below, above-mentioned left regulating arm front end connects an eccentric bracket panel, on the eccentric bracket panel periphery rotation moving knife is housed, adorns a movable knife disc on the right regulating arm; Described hay rake structure is to fix a mandrel in left and right regulating arm upper end, and the mandrel right-hand member is connected with movable knife disc, and left end is connected with the plum blossom dish, and plum blossom is coiled in the inboard of eccentric bracket panel, is installed with planet axis between movable knife disc and plum blossom dish, and the planet axis left end connects a connecting lever axle; Described cutting mechanism is to adorn a stationary knife between two grass dividers in the preceding lower end of frame, and a moving knife is established in the stationary knife top, and moving knife is fixed on the knife bar, pressuring blade device is equipped with in the moving knife top, the pendulum ring is housed above frame one side moving knife, and the pendulum ring drives swing arm by balance staff, and the swing arm lower end is connected with bearing; Described profiling grass transmitting machine structure is that top roll and lower roll vertically are housed above the central rack stationary knife, one group of slide block is respectively adorned at the top roll two ends, a baffle plate is respectively established at the slide block two ends, upper end of slide block is equipped with holddown spring, lower roll connects one group of sprocket wheel by chain, sprocket wheel one side and gear link, and are connected with top roll by chain again, establish careless plate at lower roll and the tangent place of stationary knife; Described grass binding strip mechanism respectively adorns a fanning strip in last careless plate both sides, is provided with symmetrical fanning strip in the rear end of top roll and lower roll, adorns a curved slab above the top roll rear end.
The utility model compared with prior art, divide grass thoroughly, when harvesting artificial planting herbage, native grass, the facility straw winding, it is little that careless resistance is hugged in layering, and cuttting cleaning rate height, cuttting cleaning rate reach more than 97%, can gather in the herbage of various natural, artificial plantings, also can gather in the herbage in the woods grass double as tree row.Have the complete machine reliable operation, safety factor is more than 95%, novel structure, easy to operate, and characteristics such as adaptability is strong are specially adapted to patch, the hillside fields operation, climbing capacity is strong, radius of turn 80cm; Disorderly, slivering is not laid in the field to the grass that is cut, and is convenient to mechanical bundling, is a kind of desirable small-sized grass harvester tool.
