Abstract
The utility model relates to a two-way rotary cutting hand lawn trimmer. The utility model uses a two-way rotary small gasoline engine as dynamic force, the separation and combination of the dynamic force is controlled by the rotary speed of a centrifugal clutch, a driving shaft acts on a rotary knife which is provided with a two-way cutting edge, and high speed operation is used for realizing positive direction and reverse direction cutting operation. Because the utility model adopts the two-way rotary small gasoline engine as dynamic force for driving the rotary knife with two-way cutting, the utility model can cut at positive direction, when the utility model works for a period of time and the cutting edge is passivated or the felling direction of grass is unfavorable for cutting, the utility model can run at reverse direction under the condition of no increase of a reversing driving device, the function of the cutting edge of the rotary knife can be exertd, and the operating time of the utility model can be extends one time without exchange of cutting tool. The utility model can enhance labor production efficiency and simplify driving devices.
Description
The utility model relates to a kind of machinery of realizing the hand-held turf-mown operation of positive and negative two-way rotation cutting.
The existing cutter hand-held lawn mower that revolves for simplifying transmission mechanism, reduces transmission loss, and generally adopting former traditional unidirectional rotary engine is power, is equipped with the cutting tool of unidirectional cutting edge, carries out unidirectional rotary operation; Now can be with reference to " graden machine " of China Forest publishing house publication and the books such as " gardens facility " of Beijing science tech publishing house publication, all provable this point.The weak point of its existence is: when the direction of rotation of the direction of careless strain lodging and cutting tool was consistent, cutter had passivation to paddle over by sky above careless strain slightly, and the generation leakage is cut.If change the sharp new cutter of sharpening, then expending time in makes operating efficiency descend too much.
The purpose of this utility model is that a kind of lawn mower will be provided, and it improves cut quality, prolongs the cycle that sharpening of cutter uses under the prerequisite of weight that does not increase machinery and transmission mechanism complexity.
The purpose of this utility model is achieved in that when the careless strain on lawn lodges left, and the Mechanical Driven cutter is rotated from left to right, and the cutting edge of using the cutter right side cuts; Otherwise, if when the careless strain on lawn lodges, the Mechanical Driven cutter is rotated from right to left to the right, use the cutting edge cutting in cutter left side.
The utility model makes cutter always realize swinging to cutting against grass, has improved cutting effect; Can utilize the left and right two-way cutting edge work of cutter again, one promptly is equivalent to two single-point tools to double-point tool, so can prolong one times of tool changing sharpening cycle.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.
The utility model basic structure is as shown in Figure 1: revolve cutter (4) by two-way rotary engine assembly (1), centrifugal clutch (2), power transmission shaft (3) and two-way cutting edge and form.
Specify working condition of the present utility model below in conjunction with Fig. 1.
This lawn mower is with up-to-date " two-stroke bidirectional rotation put-put " (1) (patent No.: 95202428.4) be power, automatically control centrifugal clutch (2) by the rotating speed of engine, power is passed to novel two-way cutting edge through power transmission shaft (3) revolve cutter (4), carry out cutting operation.This two-way cutting edge revolves cutter (4) concrete structure as shown in Figure 2: be made up of cutter hub (1), coupling bolt (2) and double-edged blade (3).After being rotated in the forward work a period of time, when if unfavorable cutting is swung in blade passivation or careless strain, under the condition that does not increase reverse drive equipment, but back-to-back starting engine also, utilize the opposite side cutting edge of cutter, proceed the turf-mown operation,, improve service life, operating efficiency and cutting power and the operation quality of facility to realize reducing the subsidiary operation time that sharpening is carried out in tool changing.
Claims (1)
- A kind of hand-held lawn mower of positive and negative two-way rotary-cut mainly is made up of small gasoline engine, centrifugal clutch, the power transmission shaft of two-way rotation and the cutter that revolves with two-way cutting edge; It is characterized in that: the small gasoline engine that adopts two-way rotation is a power, is equipped with the cutter that revolves with two-way cutting edge, realizes the positive and negative two-way rotation cutting operation of this machine.
