Description

The manpower grass mower

Technical field

The utility model relates to the farm machinery technical field, belongs to a kind of manpower grass mower.

Background technology

At present, the instrument of harvesting crops still is traditional reaping hook and modern large and small type grain header, Motor-driven harvester in the mountain area, upper level, hilly country can not use, and cost is higher, though reaping hook flexibly, conveniently, labour intensity is big, and efficient is lower.

For the lawn of urban greening plantation, wherein have very major part not prune with the lawn machine, but manually with reaping hook cut many, same labour intensity is big, efficient is lower.

Summary of the invention

The purpose of this utility model provides a kind of manpower grass mower, and it is simple in structure, easy to use, high efficiency, labour intensity are low, both has been fit to the large tracts of land operation, is fit to scattered fritter again, and is flexible.

For achieving the above object, the utility model is taked following design:

A kind of manpower grass mower is characterized in that: be provided with a U-shaped slide rail underframe, be provided with cross one another arc cutter and arc bottom knife in U-shaped slide rail underframe; Afterbody left side at U-shaped slide rail underframe is fixedly connected with the left hand barre, is rotatably connected to a main shaft on the afterbody right side of U-shaped slide rail underframe, is connected with an active connecting plate on this main shaft, and this initiatively connects right hand barre in the rear portion of connecting plate; Postmedian at U-shaped slide rail underframe is connected with a crossbeam, and this crossbeam is provided with a driven shaft, is connected with a follower lever on this driven shaft; Front end at the active connecting plate is hinged with an interlock plate, and the other end of this interlock plate and cutter rear end and follower lever front end are hinged jointly;

Front end at U-shaped slide rail underframe is respectively arranged with left driven shaft and right driven shaft, and the middle part of this left side driven shaft and left knife rest plate is rotationally connected, and the front end of this knife rest plate and the front end of cutter are hinged, and the rear end of this knife rest plate and the rear end of bottom knife are hinged; The right knife rest lath that is rotationally connected on this right side driven shaft, the front end of this knife rest lath and the front end of bottom knife are hinged.

Be connected with press strip on the rear and front end on bottom knife top, this cutter is in the press strip bottom.

Left side at U-shaped slide rail underframe is provided with striker plate, is provided with flitch in the preceding left side of left knife rest plate.

Curved edge place at upper and lower blade is provided with the zigzag edge of a knife, the groove of cutter down, the groove of bottom knife is up.

The utility model has the advantages that: simple in structure, easy to use, high efficiency, labour intensity are low, both have been fit to the large tracts of land operation, are fit to scattered fritter again, and be flexible.
