Background

With the enlargement of the planting area of the fruit and vegetable tea, the artificial weeding effect is good, the cost is low, but the efficiency is low, and the requirement of scale planting is not met; the chemical weeding efficiency is high, time and labor are saved, but crops are easily injured, the pesticide residue is high, the quality of agricultural products is affected, and operators need to pay attention to the safety of the agricultural products when spraying the agricultural products; the disc type weeding cutter is adopted in the mechanical weeding mower in the market, the efficiency is high, but the disc type weeding cutter is easy to break and fly out when encountering rough ground or larger stones, foreign matters and other mowing cutters, and serious safety accidents are possibly caused.

Disclosure of Invention

The invention aims to provide a Y-shaped roller flail knife structure of a mower, which utilizes a belt to drive a knife shaft to rotate, can crush cut weeds, and can be retracted under the conditions of uneven ground or larger stones, foreign matters and the like, thereby avoiding the breakage and flying out of the mower and reducing the risk of safety accidents.

According to the technical scheme provided by the invention: the Y-shaped roller flail knife structure of the mower comprises a driving belt pulley, a V-belt, a driven belt pulley, a mower knife shaft, a mower knife fixing bolt, a mower knife and a mower knife fixing nut, wherein the V-belt is wound on the driving belt pulley and the driven belt pulley, the driving belt pulley and the V-belt drive the driven belt pulley to rotate, the driven belt pulley is fixed with the mower knife shaft through a flat key, the mower knife is arranged on the mower knife shaft, the two mower knives are symmetrically arranged, and the mower knife shaft is connected with the mower knife shaft through the mower knife fixing bolt and the mower knife fixing nut.

As a further improvement of the invention, the mowing knives are arranged on the knife seats of the cutter shaft, the knife seats are fixed on the cutter shaft in a welding mode, 15 sets of the mowing knives are divided into three groups, the three groups are uniformly distributed in the rotating direction of the mowing knives, and the mowing knives are distributed in the axial direction of the cutter shaft at intervals of 55mm, 90mm, 125mm or 155 mm.

As a further improvement of the invention, the mowing knife is Y-shaped.

Compared with the prior art, the invention has the characteristics and advantages that:

the belt is used for driving the cutter shaft to rotate, so that weeds can be cut and simultaneously crushed, the grass cutter can be retracted by adding the avoidance mechanism of the grass cutter under the conditions of encountering uneven ground or larger stones, foreign matters and the like, the resistance is increased, the grass cutter can automatically avoid, the grass cutter is prevented from breaking and flying out, and the risk of safety accidents is reduced.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1-4, 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 working principle and the working process of the invention are as follows:

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.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
