Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1-fig. 1, the Y-shaped roller flail knife structure of the grass cutter of the present invention mainly comprises a driving belt pulley 1, a V-belt 2, a driven belt pulley 3, a grass cutter shaft 4, a grass cutter fixing bolt 5, a grass cutter 6 and a grass cutter fixing nut 7. The V-belt 2 is wound on the driving belt pulley 1 and the driven belt pulley 3, the driving belt pulley 1 and the V-belt 2 drive the driven belt pulley 3 to rotate, the driven belt pulley 3 is fixed with the mower cutter shaft 4 through a flat key, the mower cutter shaft 4 is provided with the Y-shaped mower cutters 6, the two Y-shaped mower cutters 6 are symmetrically arranged and connected with the mower cutter shaft 4 through the mower cutter fixing bolts 5 and the mower cutter fixing nuts 7.
Furthermore, the mowing knives 6 are arranged on knife seats 10 of the knife shaft, the knife seats 10 are fixed on the knife shaft 4 in a welding mode, 15 sets of the mowing knives are divided into three groups, the three groups of the mowing knives are uniformly distributed in the rotating direction of the mowing knives 6, and the flail knives of the mowing machine are arranged in the axial direction of the knife shaft 4 at intervals of 55mm, 90mm, 125mm or 155 mm.
Further, the mowing knife 6 is Y-shaped.
The utility model discloses a theory of operation and working process:
the mower engine drives a driven belt pulley 3 to rotate through a driving belt pulley and a V-belt 2, and the driven belt pulley 3 is fixed with a mower cutter shaft 4 through a flat key and rotates synchronously; the Y-shaped mowing knives 6 are arranged on the cutter shaft of the mower at a certain interval, the two Y-shaped mowing knives 6 are symmetrically arranged and are connected with the cutter shaft 4 of the mower through mowing knife fixing bolts 5 and mowing knife fixing nuts 7, and meanwhile, the Y-shaped mowing knives can swing by taking the mowing knife fixing bolts 5 as centers; when the engine drives the cutter shaft 4 of the mower to rotate, the Y-shaped mowing knife 6 extends out (the state of a serial number 8 in figure 1) under the action of centrifugal force to cut and crush weeds, and when the weeds meet the conditions of uneven ground or large stones, foreign matters and the like, the resistance is increased, and the Y-shaped mowing knife 6 can retreat backwards (the state of a serial number 9 in figure 1) by taking the mowing knife fixing bolt 5 as a center, so that the effect of protecting the Y-shaped mowing knife 6 is achieved, and meanwhile, the risk of safety accidents is reduced.
