Detailed Description

The present application is described in further detail below with reference to the attached drawings.

As shown in fig. 1 and 2, the cutting mechanism for the weeding machine comprises a mounting seat 1, wherein a plurality of cutting knives 2 used for being embedded into soil are rotatably connected to the lower end surface of the mounting seat 1, the cutting knives 2 are uniformly distributed along the length direction of the mounting seat 1, and a driving mechanism 3 used for driving the two adjacent cutting knives 2 to rotate towards opposite directions is arranged on the mounting seat 1.

When being applied to the weeder with above-mentioned cutting mechanism, earlier with in all cutting knife 2 embedding soil, then utilize actuating mechanism 3 control all cutting knife 2 synchronous revolution to the rotation direction of controlling two adjacent cutting knife 2 is opposite.

At the moment, the two adjacent cutting knives 2 can be used for mincing the grass diameter of the weeds, and when the grass diameter of the weeds is minced, the cutting knives 2 carry out rotary tillage on the soil, and the root systems of the weeds in the soil are turned out and minced, so that the weeds are thoroughly removed.

Meanwhile, the minced weeds are turned into the soil again, and the weeds are decomposed to provide certain nutrients for the plants or the tobaccos, so that the effect of automatic fertilization is achieved, and the normal growth and the robust growth of the plants or the tobaccos are ensured.

As shown in fig. 1 and 2, the mounting base 1 is hollow and forms a cavity 11, and the driving mechanism 3 includes a plurality of rotating shafts 31 vertically disposed in the cavity 11. The lower end of each rotating shaft 31 extends to the outside of the mounting seat 1 and is used for fixing the cutting knife 2, and the outer wall of one end of each rotating shaft 31, which is positioned in the cavity 11, is provided with a driven gear 32 which is meshed with each other.

As shown in fig. 1 and 2, a driving shaft 33 is vertically and rotatably connected in the cavity 11, an upper end of the driving shaft 33 extends to the outside of the mounting base 1 and is provided with a mounting joint 34, and an outer wall of the driving shaft 33 in the cavity 11 is provided with a driving gear 35 engaged with any one of the driven gears 32.

When the cutting knife 2 is controlled to rotate, the mounting joint 34 is firstly connected with a driving source of the weeding machine, so that when the weeding machine works, the driving source of the weeding machine drives the mounting joint 34 to synchronously rotate, and at the moment, the mounting joint 34 can be used for driving the driving shaft 33 and the driving gear 35 to synchronously rotate.

Other pivot 31 synchronous revolution can be controlled through intermeshing's driving gear 35 and driven gear 32 afterwards to because gear engagement's particularity, can realize two adjacent cutting knife 2 and revolve to opposite stable control, thereby realize ruderal stable clearance.

As shown in fig. 2 and 3, the cutting blade 2 includes a mounting plate 21 fixed to the lower end of the rotating shaft 31 and blades 22 vertically disposed on both sides of the mounting plate 21. The upper ends of a pair of blades 22 on each cutting blade 2 are close to each other and the lower ends are far from each other, and are provided in an integral molding shape with the mounting plate 21.

As shown in fig. 2 and 3, the cutting edges 23 are disposed on the sides of the pair of blades 22 facing away from each other, and the positions of the pair of blades 22 on two adjacent cutting blades 2 are staggered. The lower end of the blade 22 is arranged in an inclined manner, one end close to the cutting edge 23 is lower than the other end, and baffles 12 are vertically arranged on two sides of the mounting seat 1.

Because the position of a pair of blade 22 on two adjacent cutting knife 2 is crisscross form setting, consequently the crossing position between two cutting knife 2 of a pair of blade 22 on two cutting knife 2 with two liang of relative motion, cooperates cutting edge 23 again simultaneously, can realize the cutting in miscellaneous grass footpath and the continuous crushing of weeds root system.

Because the lower extreme of a pair of blade 22 on every cutting knife 2 is the form setting that expands outward, consequently in the rotary engineering of blade 22, can realize the cutting of weeds root system simultaneously and rub with the jack-up of soil large tracts of land, improve the effect of loosening the soil to soil, realize ruderal thorough clearance simultaneously.

And when the cutting knife 2 rotates, the baffle 12 is arranged to be matched with the blade 22, so that the cutting and the smashing of weeds are realized, and the thorough cleaning of the weeds is realized. Meanwhile, the splashed soil can be effectively blocked, and the plants or tobacco can be prevented from being injured by the splashed soil.

As shown in fig. 2 and 3, the cutting edge 23 includes a first cutting edge 24 and a second cutting edge 25 located below the first cutting edge 24, the first cutting edge 24 is vertically disposed, the second cutting edge 25 is obliquely disposed, and the lower end of the second cutting edge is gradually away from the lower end of the first cutting edge 24. The width of the blade 22 is gradually reduced from top to bottom, one side of the blade 22 departing from the cutting edge 23 is inclined, and the lower end of the blade is inclined in the same direction as the second cutting edge 25.

By providing the lower end of the blade 22 with a sharp shape during use and operation of the blade 22, the contact area with the soil is reduced, so that the blade 22 can more easily penetrate into the soil. Meanwhile, the width of the blade 22 is gradually reduced from top to bottom, so that the crushing effect of the blade 22 on soil is increased, the resistance of the soil to the blade 22 is reduced, the shearing force of the connecting position of the blade 22 and the mounting disc 21 is reduced, the phenomenon of fracture of the blade 22 is avoided, and the service life of the blade 22 is ensured.

As shown in fig. 2 and 3, the outer wall of the lower end of the rotating shaft 31 is sleeved with a protection plate 4 located below the mounting seat 1, and the outer edge of the protection plate 4 is provided with a protection ring 41 in an upward bending manner.

As shown in fig. 2 and 3, a through hole 26 through which the rotating shaft 31 passes is provided in the mounting plate 21, and a bolt 27 that is screwed to the rotating shaft 31 and is used to press and fix the mounting plate 21 to the fender panel 4 is provided on the lower end surface of the mounting plate 21.

When pivot 31 drove cutting knife 2 and moves, will drive guard plate 4 and protective shroud synchronous motion, shelter from the crossing position of pivot 31 and mount pad 1 through utilizing guard plate 4 and protective shroud this moment, avoid weeds or soil to splash to mount pad 1 in to effectual whole cutting mechanism's of assurance normal work and stable work.

When the cutting knife 2 needs to be replaced, the bolt 27 is directly unscrewed, and the cutting knife 2 can be detached. After the outer wall of pivot 31 is located with new cutting knife 2 cover afterwards, the bolt 27 of screwing can realize cutting knife 2's fixed to realize cutting knife 2's quick installation and quick maintenance change.

The working principle is as follows: when the cutting mechanism is applied to a weeding machine, all the cutting knives 2 are embedded into soil, and then all the cutting knives 2 are controlled to synchronously rotate by the driving mechanism 3, and the rotating directions of two adjacent cutting knives 2 are controlled to be opposite. At the moment, the grinding of the grass diameter of the weeds and the turning of the root systems of the weeds are realized, the rotary tillage and the soil loosening of the soil are realized at the same time, the ground weeds are turned into the soil again, and the decomposition of the weeds is utilized to provide certain nutrients for the plants or the tobaccos, so that the normal growth and the robust growth of the plants or the tobaccos are ensured.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
