Abstract
The utility model discloses a lawn mower cutting blade arrangement structure capable of realizing horizontal rotation double blade mowing, wherein two blades are arranged on the same horizontal plane to replace the common structure which only adopts a single blade; therefore, on the premise of ensuring mowing breadth, the utility model reduces the size of each blade to reduce the starting current of a mowing motor and increase the safety of the motor and a control circuit. In order to match with the double blade structure, the utility model designs an 8-shaped blade cavity which is matched with the double blade, thereby realizing the functions of mowing and timely chopping; thus, the utility model crushes mowed grass and directly returns the crushed grass to a lawn as nutrient, thereby omitting the operation of collecting broken grass.
Description
Technical field
The utility model relates to a kind of mowing structure of mower, is specifically related to a kind of mower blade arrangement that double-pole is mowed that horizontally rotates.This structure is fit to be applied on the low power wireless mower very much, is particularly useful on wireless rechargeable the remote control mower and full-automatic mower.
Background technology
The mowing mode of existing mower can roughly be divided into and horizontally rotates that blade is mowed and hobboing cutter mowing two big classes, normally utilizes a blade to horizontally rotate mowing at a high speed and horizontally rotate the mowing blade.This blade arrangement structure is installed comparatively simple, and easy to maintenance, but that limitation is a starting current is very big, damages motor easily, even burns control circuit.
Summary of the invention
The purpose of this utility model provides a kind of novel mower blade arrangement, in the low mowing electric motor starting electric current of prerequisite decline of the certain mowing width of maintenance, the safety of protection motor and control circuit.
The technical solution of the utility model is as follows: a kind of mower blade arrangement that horizontally rotates the double-pole mowing, comprise two blades that place in the mowing machine knife chamber, two blades are horizontally installed on the same horizontal plane, and two blades are connected separately with two drive motors respectively.
The aforesaid mower blade arrangement that horizontally rotates the double-pole mowing, wherein, described mowing machine knife chamber is figure of eight cutter chamber.
The aforesaid mower blade arrangement that horizontally rotates the double-pole mowing, wherein, the distance between blade and the cutter chamber is less than 5mm.
The beneficial effects of the utility model are: owing to adopted two drive motors independently to drive two blades, reduced the starting current of machine startup moment, improved the safety and the reliability of motor and control circuit.
Description of drawings
Fig. 1 be existing mower one the structural representation of the horizontal rotating blade of high speed;
Fig. 2 is the arrangement schematic diagram of the horizontal high speed rotating blade of the utility model double-pole;
Fig. 3 is the structural representation in the utility model figure of eight hay knife chamber;
Fig. 4 is the assembling schematic diagram in double-pole of the present utility model and cutter chamber.
Among the figure, 1. 3. double-pole blades, 4. figure of eight cutter chambeies, hilted broadsword blade 2. cutter chambeies, 5. colters
Embodiment
For a more detailed description below in conjunction with accompanying drawing to profile of the present utility model and structure.
In conjunction with the accompanying drawings 2, be double-pole arrangement of the present utility model, two blade arrangement are on same horizontal plane, and two blades are connected separately with two drive motors respectively.
In conjunction with the accompanying drawings 3, be the structure in the utility model figure of eight cutter chamber, on longitudinal centre line, arranged a leg-of-mutton colter that is used for the branch grass.
In conjunction with the accompanying drawings 4, be double-pole of the present utility model and " 8 " the assembling schematic diagrames in font cutter chamber.Also require the function of broken grass in order not only to realize mowing, the required distance in blade and cutter chamber is less than 5mm.
The utility model is because adopted two drive motors independently to drive two blades, and the radius of gyration when supposing hilted broadsword is 50cm, and the average torsion during mowing is 1 N, and then required moment of torsion is 0.5/2 * 1 * 2=0.5 ox rice; After adopting double-pole, the radius of gyration of every blade is 25cm, and average torsion is 0.5 N, and every is the required moment of torsion of cutter 0.25/2 * 0.5 * 2=0.125 ox rice, and it is 0.25 N of rice that two cuttves are added up, half when being hilted broadsword.
Claims (3)
1. one kind horizontally rotates the mower blade arrangement that double-pole is mowed, and it is characterized in that: comprise two blades that place in the mowing machine knife chamber, two blades are horizontally installed on the same horizontal plane, and two blades are connected separately with two drive motors respectively.
2. the mower blade arrangement that horizontally rotates the double-pole mowing as claimed in claim 1, it is characterized in that: described mowing machine knife chamber is figure of eight cutter chamber.
