This electric mower is through installing four 12v motors on the rotatable knife rest and driving the rotatory weeding of cutter head, and there is adjustable locating wheel knife rest central authorities, control knife rest ground clearance, has two automatic re-setting touch switch of symmetry on the knife rest, and control cutter head electromagnetic clutch outage and switch on gear motor drive cutter rest counter-rotation when touchhing waveform guardrail stand to bypass the stand of waveform guardrail, reach the automatic mesh of weeding in succession.

The upper and lower support frames form a herringbone, the upper support frame and the lower support frame can rotate around the trailer fixed shaft in a limited manner respectively, the lower support frame is an adjustable tensioning type support, the positioning roller and the waveform guardrail are tightly attached, a power supply controller is arranged at the top end of the outer sleeve, the control system supplies power continuously and the speed reduction motor is started, stopped and rotated forward and backward, the power is supplied by a storage battery with 12V main power, the grass mower can be mounted on a trailer or a self-propelled machine, continuous weeding operation is carried out on a central separation belt or a road shoulder, and manpower and material resources are greatly saved.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic view of the structure of the present invention;

fig. 2 is a schematic view of the top-down structure of the upper and lower supporting frames of the present invention.

Detailed Description

An electric grass trimmer for roads is shown in figures 1 and 2 and comprises a trailer 10, wherein a fixed shaft 11 is vertically arranged on the trailer 10, the top end of the fixed shaft 11 is rotatably connected with an upper support frame 14, the free end of the upper support frame 14 is vertically and fixedly provided with an outer sleeve 2, a rotating shaft 21 is arranged in the outer sleeve 2 in a matching and sleeving manner, the upper end of the rotating shaft 21 is connected with a speed reducing motor 15 vertically arranged at the top end of the outer sleeve, the lower end of the rotating shaft 21 is connected with a rotating tool rest 22 through an electromagnetic clutch 3 arranged in the lower part of the outer sleeve 2, two motors 4 are respectively arranged on the rotating tool rests 22 at two sides of the rotating shaft 21 at vertical intervals, the lower ends of the rotating shafts of the motors 4 are respectively provided with tool pans 5, 6, 8 and 9, a positioning wheel 7 is arranged below the bottom surface of the center of the rotating tool rest 22, two sides, the automatic reset touch switch 19 is connected with a power supply controller 1, a motor forward and reverse rotation control circuit is arranged in the power supply controller 1, the power supply controller 1 is arranged at the upper part of the outer sleeve 2, a positioning roller 16 is vertically arranged on one side wall of the outer sleeve above the electromagnetic clutch, and the positioning roller 16 is abutted against a road waveform guardrail 17; an auxiliary fixed shaft 20 is also vertically and fixedly arranged on the top surface of the trailer, a lower support frame 13 is sleeved on the auxiliary fixed shaft 20, a spring 12 is arranged on the inner side of the lower support frame 13 to form an elastic telescopic lower support frame, and the outer side of the lower support frame is sleeved with the middle part of the outer sleeve 2.
