Abstract

A lawn trimmer comprises a trimming head, a drive motor and a machine frame. The trimming head comprises a mounting rack, a bearing, a driven rotating shaft, an idler wheel and a cutting knife. The inner ring of the bearing is fixed to the center of the mounting rack, the outer ring of the bearing is fixedly connected with the driven rotating shaft, a fixing rod on the idler wheel and the bearing are concentrically fixed to the mounting rack, the drive motor drives the driven rotating shaft through a driving belt, the cutting knife is arranged on the driven rotating shaft, and the trimming head is hinged to the machine frame. According to the lawn trimmer, the idler wheel is arranged on the trimming head, and the height of the idler wheel is adjustable, so that the height of the trimmed lawn is uniform, a worker does not need to trim the lawn by holding the trimmer with hands, and manpower is saved; the trimming head is hinged to the machine frame, the trimming head and the ground can be kept in a horizontal level when the worker pulls the machine frame, and the trimming quality is guaranteed; the idler wheel is arranged on the trimming head and is arranged in the center of the trimming head, and the worker is less influenced by different ground conditions when dragging the lawn trimmer.

Description

Lawn mower

Technical field

The present invention relates to a kind of lawn mower.

Background technology

At present, hand-held portable lawn mower needs staff holding frame when operation, and the cutting range on lawn depends on the height of staff's terminal frame, therefore, the lawn height of pruning out differs, and affects attractive in appearance, and staff's labour intensity is also larger.

Summary of the invention

The shortcoming existing in order to overcome above-mentioned prior art, the object of the present invention is to provide a kind of pruning head can drop on lawn, reduces the lawn mower of labour intensity.

In order to address the above problem, the present invention is by the following technical solutions: a kind of lawn mower, comprise and prune head, drive motors and frame, it is characterized in that, described pruning head comprises installing rack, bearing, driven spindle, roller and cutter, the inner ring of described bearing is fixed on the center of described installing rack, the outer ring of described bearing is fixedly connected with described driven spindle, dead lever on described roller is fixed on installing rack with bearing is concentric, described drive motors drives driven spindle by driving-belt, and described cutter is arranged on driven spindle.

Further, the dead lever of described roller is external thread rod, on described installing rack, fixes a riffled tube matching with described dead lever with described bearing concentric position.

Further, described pruning head is hinged with frame.

Further, the front end in described frame is provided with handle.

The invention has the beneficial effects as follows:

1, its pruning head is provided with roller, and the height of roller is adjustable, thereby makes the lawn high unity pruned out, and does not need staff holding trimmer to prune, and has saved labour.

2, its pruning head and frame are hinged, when staff pulls frame, can make to prune head and ground maintenance level, guarantee to prune quality.

3, a roller is set pruning on head, and roller is arranged on the center of pruning head, staff is subject to ground condition to affect less when dragging trimmer.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is described further:

Fig. 1 is overall structure schematic diagram of the present invention;

Fig. 2 is that the present invention prunes a driven spindle phantom.

In figure, 1 prunes head, 11 bearings, 111 inner rings, 112 outer rings, 12 driven spindles, 13 rollers, 131 dead levers, 14 cutteves, 15 installing racks, 2 drive motors, 3 frames, 4 driving-belts, 5 riffled tubes, 6 handles.

Embodiment

Below in conjunction with accompanying drawing, the present invention is described in further details:

As depicted in figs. 1 and 2, specific embodiments of the invention comprise prune 1, drive motors 2 and frame 3.

Described pruning 1 comprises bearing 11, driven spindle 12, roller 13, cutter 14 and installing rack 15, the inner ring 111 of described bearing 11 is fixed on the center of described installing rack 15, driven spindle 12 is cylinder type, and it is directly enclosed within 112Hou Yu outer ring, outer ring 112 welding of described bearing 11.Described drive motors 2 is arranged on center one side of installing rack 15, and it drives driven spindle 12 by driving-belt 4, and described cutter 14 is arranged on driven spindle 12.

Dead lever 131 on described roller 13 is fixed on installing rack 15 with bearing 11 is concentric,

Preferably, in the present embodiment, the dead lever 131 of described roller 13 is external thread rod, on described installing rack 15, fixes a riffled tube 5 matching with described dead lever 131 with described bearing 11 concentric positions (being positioned at bearing inner race 111).Roller 13 is threaded connection on installing rack 15, during connection, can on dead lever 31, overlap Upper gasket, so just can regulate the height of roller, thereby determines the cutting range on lawn.

In order to prevent that staff from pruning 1 run-off the straight when dragging frame 3, form angle with ground after cutter 14 contact with ground, described pruning 1 and frame 3 are hinged, like this, frame 3 prunes 1 when moving up and down just can not run-off the straight.

In order to facilitate staff's frame 3 walking in tow, at the front end of described frame 3, be provided with handle 6.

The above is the preferred embodiment of the present invention, for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, and these improvements and modifications are also regarded as protection scope of the present invention.
