Abstract
A cutting-off tool assembly of a lawn mower solves the problem that a lawn mower in the prior art is low in working efficiency. The cutting-off tool assembly of the lawn mower is characterized by comprising a knife rest, a vertical shaft, a connecting rod, an oscillating bar, a fixed blade and a movable blade. The knife rest is connected with the lawn mower, the vertical shaft is connected with a lawn mower power mechanism, the connecting rod is hinged to an eccentric position of the vertical shaft, the oscillating bar has rotational freedom, the fixed blade is fixedly connected with the knife rest, the movable blade is connected with the fixed blade in a sliding mode, one end of the connecting rod is hinged to the driving end of the oscillating bar, the driven end of the oscillating bar is connected with the movable blade in a sliding mode with one direction freedom degree, and the movable blade and the fixed blade are provided with cutting teeth which are in sliding fit. The lawn mower power mechanism drives the vertical shaft to rotate, the connecting rod is driven by the eccentric position of the vertical shaft to drive the oscillating bar to swing in a reciprocating mode, the reciprocating motion of the oscillating bar drives the movable blade to do reciprocating motion, the cutting teeth on the movable blade and the cutting teeth on the fixed blade are interlaced in a reciprocate mode, and therefore an object between the cutting teeth is cut.
Description
Technical field
The utility model relates to a kind of grass mower cutter assembly.
Background technology
Along with the development of economic society, the owning amount on lawn is more and more higher in the city, has not only beautified the appearance of the city, but also can keep the cleaning of air, becomes an obligato important component part in the city.But the lawn needs to safeguard regularly, prunes and maintains, to guarantee the smooth of lawn.Therefore hay mower begins a large amount of appearance, and its output and social owning amount increase substantially.The power mower of China's production at present generally all is made up of generator, handrail, knife rest, cutter, and rotary cutting knife is designed to one or two, is positioned at the leading section of knife rest, and rotary cutting knife is rotation at a high speed under the drive of engine, realizes the purpose that cuts the grass on a lawn.But the mower of this kind structure is owing to only design one or two rotary cutting knifes, and the single file area coverage is little, the pruning on only suitable small-sized lawn, for large-scale lawn such as football pitch, golf course etc., require a great deal of time and just can finish pruning, inefficiency, labour intensity is big.
The utility model content
The utility model is intended to provide a kind of grass mower cutter assembly, to solve the ineffective problem of mower in the prior art.
Grass mower cutter assembly in this programme, it is characterized in that: comprise the knife rest, the vertical pivot that is connected with mower power that are connected with grass mower, be hinged on connecting rod on the eccentric position of vertical pivot, with hinged fork, the fixed blade of fixedlying connected with knife rest of knife rest and the movable blades that is slidingly connected with fixed blade, one end of connecting rod and the drive end of fork are hinged, the driven end of fork and movable blades are to have being slidingly connected of a direction degree of freedom, the tooth that cuts that being equipped with on movable blades and the fixed blade slides fits.
Vertical pivot rotates under the drive of mower actuating unit, connecting rod drives the fork reciprocally swinging under the driving of the eccentric position of vertical pivot, the reciprocally swinging of fork driven end driving movable blades moves back and forth then, and the tooth that cuts on movable blades and the fixed blade back and forth interlocks to realize cutting the between cog objects of cutting.
Further, described vertical pivot is provided with the belt pulley that is connected with mower power, but movable blades be slidingly connected on the fixed blade in the mode of move left and right, movable blades is provided with chute, the driven end of fork is provided with the slide block that cooperates with described chute.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the front elevational schematic of the utility model embodiment.
Fig. 2 is the schematic top plan view of the utility model embodiment, and the eccentric bit position of vertical pivot is analysed and observe for disconnecting among the figure.
Fig. 3 is the schematic perspective view of the utility model embodiment.
Embodiment
As Fig. 1,2, shown in 3: the grass mower cutter assembly in this enforcement comprises the knife rest 1 that is connected with grass mower, the vertical pivot 2 that is connected with mower power, be hinged on the connecting rod 3 on the eccentric position of vertical pivot, the fork 4 hinged with knife rest, the fixed blade 5 of fixedlying connected with knife rest and the movable blades 6 that is slidingly connected with fixed blade, vertical pivot 2 is provided with the belt pulley 21 that is connected with mower power, one end of connecting rod 3 and vertical pivot off-centre position 22 are hinged, the drive end 41 of its other end and fork 4 is hinged, movable blades is provided with the chute 61 of U-shaped longitudinally, and the driven end 42 of fork 4 is provided with the slide block 43 that cooperates with described chute 61.Being equipped with on movable blades and the fixed blade slide to fit cut tooth 7.
As described in Figure 3, movable blades passes bar hole 51 that fixed blade is provided with to realize horizontal slippage.
The working method of above-mentioned cutter assembly is as follows: knife rest 1 is connected on the grass mower by dead lever 11, vertical pivot 2 rotates under the drive of belt on the mower actuating unit, connecting rod 3 drives fork 4 reciprocally swingings under the driving of the eccentric position of vertical pivot, the reciprocally swinging of fork 4 drives movable blades 6 and moves back and forth cutting 7 reciprocal interlocking with realization to cutting the between cog objects of cutting of tooth on movable blades 6 and the fixed blade 5 then.
Above-described only is embodiment of the present utility model, and general knowledge such as known concrete structure and characteristic are not done too much description at this in the scheme.Should be understood that; for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
