Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of mowing apparatus, particularly a kind of mower device.
Background technology
Mower is widely used in urban afforestation and park and garden design, and using more is 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, blade, by High Rotation Speed after driven by engine, is pruned lawn.
A kind of mower is disclosed in patent (CN 2664364Y), comprise car body, mowing unit, broken careless unit and guide unit, wherein stalk smashing apparatus comprises a bolster being located at this car body also by the propelling rod member of this mowing unit transmission, and one group is established the broken careless unit with first of this bolster, this first broken careless unit has the fixed disk that is fixed on this bolster, first blade of array knot and this fixed disk, and one is fixed on this fixed disk and the broken careless room of formation that is fitted to each other, grow grass when mowing unit cuts off, this can be grown grass and import these broken grass indoor and arrange on meadow after cutting into short grass with the first blade.
Although this mower can realize the function of mowing, but its broken grass structure is the broken careless room of the groove sliced off being introduced multiple blade and protecting cover composition carries out broken grass, this is complex structure not only, and can not carry out the conversion of broken careless pattern and not broken careless pattern, can not adapt to different mowing demands; Also have current mower for the adjustment of mowing height all do bad, the adjustable structure that neither one is good carrys out the perfect adjustment realizing mowing height.
Summary of the invention
The object of the invention is the problems referred to above existed for existing technology, provide a kind of mower device, technical problem to be solved by this invention is under the prerequisite ensureing good mowing efficiency, improve the broken careless ability of mower.
Object of the present invention realizes by following technical proposal:
A kind of mower device, comprise a casing, power unit, mowing blade and main shaft, before and after described casing, both sides are respectively equipped with front-wheel and trailing wheel, it is characterized in that, described power unit is connected in the upper surface of casing, described mowing blade is arranged on the lower surface of casing, the installing hole running through upper and lower two end faces is offered in the middle part of described casing, described main shaft is plugged in installing hole and the two ends of this main shaft connect described power unit and mowing blade respectively, the lower surface of described casing is provided with a careless room broken with the annular of installing hole coaxial line, it is indoor that described mowing blade is positioned at broken grass.
Operation principle of the present invention is: power unit connects main shaft, main shaft connects mowing blade, mowing blade is in the indoor rotation of the broken grass of annular, drop out from grass outlet after the disconnected grass chopping driving annular broken grass in casing lower surface indoor, chopping process is carried out to disconnected grass, use mowing blade, and do not add blade and the device of other broken grass, simple and reliable for structure.
In above-mentioned a kind of mower device, the rear end of described casing is provided with a grass outlet be communicated with broken careless room, and the rear end of described casing is also provided with an end cap that grass outlet can be blocked, and described end cap and casing removably connect.When after installation end cap, disconnected grass can not leave casing from grass outlet timely, but broken grass is repeatedly cut into by mowing blade after broken careless indoor circulation, then drop from the lower end of broken careless room, removably connect between end cap and casing, the whether broken grass of selection that can be in good time, and this kind of stalk smashing apparatus structure is simply effective.
In above-mentioned a kind of mower device, described end cap is provided with several linking arms, each linking arm is equipped with a buckle, described front-wheel is connected with casing by front-wheel fulcrum, described trailing wheel is connected with casing by trailing wheel fulcrum, described buckle can with the trailing wheel fulcrum clamping of mower.One end of end cap and grass outlet against, the other end, by buckle and the clamping of trailing wheel fulcrum, makes end cap fixed.
