According to the grass trimmer with the rotatable machine head, a handrail is connected with a vehicle wheel support, a machine head mechanism is connected to the vehicle wheel support and comprises a large cover, the large cover is connected with the vehicle wheel support, the upper end of the larger cover is connected with power, the front end of the large cover is connected with a front plastic cover and a grass trimming head assembly, and a grass trimming rope is connected to the grass trimming head assembly; vehicle wheels are connected to the vehicle wheel support, at least two limiting grooves are formed in the vehicle wheel support, limiting pins are movably connected to the interiors of the limiting grooves in a clamped mode, and are connected with a swing cable switch through cables, and the swing cable switch is connected with the handrail. The grass trimmer is practical in function; the limiting pins are vertically lifted, so that the limiting pins is clamped in any limiting groove in the vehicle wheel support, and the effect of adjusting the machine head to be independent of the vehicle wheel support for independent steering is achieved; in this way, certain-angle sector weeding can be carried out, and grass in corners can be accurately removed; meanwhile, fixed-point weeding within a specific scope can be achieved, and the practicability of the grass trimmer is strengthened.
Description
Technical field
The invention belongs to agricultural mechanical field, particularly a kind of mower.
Background technology
Mower be a kind of be widely used for beating the agricultural machinery cutting various crops such as green grass or young crops (doing) maize straw, straw etc. and herbage.At present, the head of mower is all be fixedly connected with vehicle wheel frame, and head to rotate voluntarily.Still action need can be met for general weeding operation, if but when running into corner or other specific weeding operations interior among a small circle, because head can only move forward and backward with vehicle wheel frame, for extremely inconvenient during above-mentioned working environment operation, final weeding result can not meet particular/special requirement, and the practicality of mower is reduced.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of head rotary type mower is provided, by the movement of spacer pin in stopper slot, drive head rotates, to reach weeding and corner fixed point herbicidal effect in particular range, and compact conformation, easy to operate, can user demand be met, play works fine effect.
The technical scheme that the present invention is adopted for achieving the above object is: a kind of head rotary type mower, handrail connects vehicle wheel frame, vehicle wheel frame connects head section mechanism, wheel is connected on vehicle wheel frame, it is characterized in that: vehicle wheel frame has 2 stopper slots at least, stopper slot links mutually with spacer pin movably, and spacer pin is connected with swing clue switch by clue, swings clue switch and is connected with handrail.
Further, described head section mechanism comprises large case, and large case is connected with vehicle wheel frame, and large case upper end connects power, and large case front end connects front plastic jacket and moving head assembly respectively, and moving head assembly connects rope of beating the grass.
Further, the between perpendiculars rotation angle of described head section mechanism and vehicle wheel frame center is-45 ~ 45 degree.
Further, the number of described stopper slot is 2 ~ 5.
Further, the distance between described stopper slot is 2 ~ 10cm.
Practical function of the present invention, clue is pulled by swinging clue switch, and then drive spacer pin oscilaltion, with after rotation head to suitable angle, in any stopper slot that spacer pin is stuck on vehicle wheel frame, reach adjustment head carries out independent steering effect independent of vehicle wheel frame, the moving head that head connects thus just can carry out the sector weeding of certain angle, also can accurately remove the grass in corner, also can realize the fixed point weeding in particular range simultaneously, enhance the practicality of mower.
