Abstract
The invention relates to a lawn mower with double blades. The lawn mower with the double blades comprises a power source and a shell body, wherein the power source is provided with an output shaft which extends downwards, the shell body is located below the power source and is opened downwards, a first blade and a second blade are sequentially installed at the bottom of the output shaft at an interval, and the edge of the first blade is located in front of the edge of the second blade. When the power source rotates, the power source drives the first blade and the second blade to rotate synchronously. Due to the fact that an air lifting portion is arranged at the rear portion of each blade, when the blades rotate, negative pressure is formed in the shell body, and weeds are absorbed to be vertical when the weeds are placed in the negative pressure. The first blade which is in front of the second blade and located on the second blade makes contact with the head portions of the weeds and cuts the head portions of the weeds. The head portions of the weeds are cut away while the rod portions keeping vertical are reserved, then the second blade behind the first blade cuts the rod portions, one weed is cut into three sections, and especially the cut residual portions are thinner than traditionally cut residual portions.
Description
Technical field
The present invention relates to a kind of mower, be specifically related to a kind of double-deck blade mower.
Background technology
The tradition mower only has the individual layer blade.The blade of cutting off is bigger, if the grass of cutting off will be kept his usefulness, as makees feed etc., need carry out secondary and pulverize.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of double-deck blade mower that can extract comparatively meticulous grass.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of double-deck blade mower, comprise the power source that has an output shaft that stretches out downwards and be positioned at described power source below and to the housing of under shed, the bottom of described output shaft is equipped with ground floor blade and second layer blade successively at interval, and the blade position of the relative second layer blade of the blade of described ground floor blade is leading.
Further, described first, second layer blade arranges at interval, and described first, second layer blade rear end has air-lift unit portion.
The invention has the beneficial effects as follows:
Mower among the present invention is provided with double-deck blade, rotates synchronously when power source drives first, second layer blade when rotating.Because the blade rear portion is provided with air-lift unit portion, during the blade rotation, in housing, form negative pressure, when weeds place negative pressure, be subjected to inhale vertically.Horizontal level ground floor blade leading and that be positioned at second layer blade top contacts and forms cutting with the head of weeds earlier.The head of weeds is cut and is flown and leave over the bar portion that keeps vertical, with the second layer blade that arrives behind the ground floor blade bar portion is formed cutting, and weeds are cut into three sections, traditional relatively more meticulous of the remnants of defeated troops under particularly being cut.
Description of drawings
Below in conjunction with accompanying drawing double-deck blade mower of the present invention is described further.
Fig. 1 is double-deck mower structural representation among the present invention.
Fig. 2 is the structural representation of blade among the present invention.
Embodiment
Embodiment
According to illustrated in figures 1 and 2, the present invention includes have one stretch out the motor of output shaft 1 downwards and be positioned at described power source below and to the housing of under shed.
The bottom of output shaft 1 is equipped with ground floor blade 2 and the second layer blade 3 that places in the shell nozzle successively at interval, the structure of ground floor blade 2 and second layer blade 3 is identical, the blade front end has blade 4, and the rear end has for promoting air and form the air-lift unit portion 5 of negative pressure in opening.Blade 4 positions of the blade 4 relative second layer blades 3 of ground floor blade 2 are leading in the horizontal direction.
When driving first, second layer blade 2,3 when rotating, rotates synchronously power source.Because the blade rear portion is provided with air-lift unit portion 5, during the blade rotation, in housing, form negative pressure, when weeds place negative pressure, be subjected to inhale vertically.Horizontal level ground floor blade 2 leading and that be positioned at second layer blade 3 tops contacts and forms cutting with the head of weeds earlier.The head of weeds is cut and is flown and remain with the bar portion that is vertical state, and the 3 pairs of bar portions of second layer blade that arrive with ground floor blade 2 back form cutting, and weeds are cut into three sections, and the grass particularly being cut is under considered traditional relatively more meticulous of the remnants of defeated troops to be worth doing.
The above-described embodiment that is not limited to of the present invention, all employings are equal to replaces the technical scheme that forms, and all drops in the protection domain of requirement of the present invention.
Claims (2)
1. double-deck blade mower, comprise have one stretch out the power source of output shaft downwards and be positioned at described power source below and to the housing of under shed, described output shaft bottom is equipped with ground floor blade and second layer blade successively at interval, and the blade of the described relatively second layer blade of the blade of described ground floor blade is leading in the horizontal direction.
2. according to the described double-deck blade mower of claim 1, it is characterized in that: the rear end of described ground floor blade and second layer blade has for promoting air and form the air-lift unit portion of negative pressure in described opening.
