Abstract
The utility model discloses a kind of vexed careless device of mower, comprise spiral spiral case, be arranged on rotating blade in spiral spiral case and drive the motor of rotating blade, the both sides of described rotating blade are provided with cutting edge, and between two cutting edges with one end, be provided with a radial protrusion, described motor is clockwise and anticlockwise motor.This device adopts motor that can rotating, driving, with the blade of bilateral cutting function, realizes and mows and make grass bits carry out opposite direction cycle operation, thereby realize broken careless function, this structure does not need to increase any other part and blocks straw outlet, the rotating that only needs switch to control motor can realize broken careless function, can realize the broken grass of a key, and body is spiral spiral case, broken careless passage is very smooth and easy, simple in structure, cost is lower, easy to use.
Description
Technical field
The utility model relates to a kind of mower, relates in particular to the Men Cao mechanism on a kind of mower.
Background technology
Mower is widely used in urban afforestation and park and garden design, and using more is the pruning to lawn, and it generally comprises five parts: engine, running gear, blade, handrail and control section.Its operation principle is roughly: on the output shaft of engine, blade is housed, High Rotation Speed after the launched machine of blade drives, prunes lawn.On mower, be provided with vexed careless device and be again stalk smashing apparatus, stalk smashing apparatus carries out fragmentation by the grass cutting off.
The Men Cao mechanism of mower mainly contains two kinds at present, and a kind of is by increase independent part at straw outlet, straw outlet to be blocked, and realizes the vexed careless function of circulation, and shortcoming is to use inconvenience, and this part is easily lost; Another kind of mode is integrated vexed careless system, the Men Cao mechanism that for example EP1584224B1 announces, by a series of transmission, vexed careless function is integrated on complete machine, shortcoming is that cost is higher, complex structure and because structural functional requirement causes vexed careless passage not smooth, and broken careless effect is bad and easily stop up.
Summary of the invention
The utility model object is: provide a kind of simple in structure, easy to operate, the Men Cao mechanism of the mower that can not result in blockage.
The technical solution of the utility model is: a kind of vexed careless device of mower, comprise spiral spiral case, be arranged on rotating blade in spiral spiral case and drive the motor of rotating blade, it is characterized in that: the both sides of described rotating blade are provided with cutting edge, and between two cutting edges with one end, be provided with a radial protrusion, described motor is clockwise and anticlockwise motor.
Further, described rotating blade both sides are connected with middle part concave arc.
Further, described projection is connected with two cutting edge circular arcs.
Further, described projection is circular arc.
Further, the radius of described circular arc is increased to middle part successively by both sides.
Further, described motor is controlled motor positive and inverse by control button by control circuit, and described control button is installed on complete machine or on switch enclosure.
The utility model has the advantages that:
This device adopts motor that can rotating, by blades on two sides two sides, there is blade simultaneously, so also can realize mowing in the time of motor reversal, and produce reverse wind-force, utilize the irreversible guiding of spiral case and under the effect of counter blow power, grass counter motion in spiral case can not be discharged from grass outlet, thereby realize the repeatedly cutting of grass, reach the broken careless effect of vexed grass, this structure does not need to increase any other part and blocks straw outlet, the rotating that only needs switch to control motor can realize broken careless function, can realize the broken grass of a key, and body is spiral spiral case, broken careless passage is very smooth and easy, simple in structure, cost is lower, easy to use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the structural representation of the vexed careless device of the utility model mower;
Fig. 2 is the structural representation of blade of the vexed careless device of the utility model mower;
Fig. 3 is A-A cutaway view in Fig. 2 of vexed careless device of the utility model mower;
Fig. 4 is a kind of vertical view of blade of the vexed careless device of the utility model mower;
Fig. 5 is the running schematic diagram of the vexed careless device of the utility model mower.
Wherein: 1, spiral case, 2, blade, 3, bolt, 4, straw outlet, 21, cutting edge, 22, projection, 23, circular arc, 24, blade middle part, 25, blade both sides, 5, running counterclockwise, 6, running clockwise.
Embodiment
For making the purpose of this utility model, technical scheme and advantage more cheer and bright, below in conjunction with embodiment and with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these descriptions are exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, omitted the description to known configurations and technology, to avoid unnecessarily obscuring concept of the present utility model.
Embodiment:
As shown in Figure 1, the vexed careless device of a kind of mower of the present embodiment, comprises spiral spiral case 1, the outermost end of spiral case 1 is provided with straw outlet 4, in spiral spiral case 1, electric rotating machine is installed, above-mentioned motor be can rotating motor, blade 2 is fixed on the rotating shaft of motor by bolt 3.
The structure of blade as Figure 2-3, the both sides 25 of blade 2 are all provided with cutting edge 21, like this clockwise or make blade 2 can cut grass while being rotated counterclockwise, blade 2 both sides 25 and middle part 24 are connected for concave arc, between two cutting edges 21 of blade 2 with one end, be provided with a radial protrusion 22, projection 22 is connected for circular arc 23 with two cutting edges 21, when cutting grass, can give like this effect of a guiding of grass, and there is booster action, make blade 2 be difficult for fracture when rotated, play when rotated blasting action simultaneously.In order further to strengthen guide effect, above-mentioned circular arc 23 is preferably minor arc and concaves.
Be a kind of structure chart of blade as shown in Figure 4, the radius of the circular arc of projection is by both sides 25 24 increases successively to middle part.The blade structure of this kind of structure is firmer, and cutting effect is better.
On complete machine or on switch enclosure, control button is installed, by control circuit, controls motor positive and inverse.The realization of motor reversal function mainly realizes by the sense of current of switch motor input.
Work running principle is as follows:
As shown in Figure 3, blade is rotated counterclockwise at 5 o'clock, blade drives grass bits to be rotated counterclockwise 5 in spiral case 1, and can discharge from the straw outlet 4 of spiral case 1, after control button triggers, can realize blade by circuit and be converted to and turn clockwise 6 by being rotated counterclockwise 5, blade drives grass bits to turn clockwise 6 in spiral case 1, because the direction of motion is contrary with grass outlet, careless bits will be in the interior cycle operation of body 1, thereby realizes broken careless function.
Should be understood that, above-mentioned embodiment of the present utility model is only for exemplary illustration or explain principle of the present utility model, and do not form restriction of the present utility model.Therefore any modification of, making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model in the situation that not departing from spirit and scope of the present utility model.In addition, the utility model claims are intended to contain whole variations and the modification in the equivalents that falls into claims scope and border or this scope and border.
