Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

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

The utility model provides a gardens weeding device's cutting knife structure, as shown in fig. 1, including the arbor 1 of vertical setting, be provided with a plurality of cutting knife layers 2 along its extending direction from the top down interval on arbor 1, every cutting knife layer 2 all includes a plurality of mowing sword 3, a plurality of mowing sword 3 on every layer set up along the circumference interval of arbor 1, every mowing sword 3 all includes mowing knife storehouse 301 and mowing blade 302, the one end fixed connection of mowing knife storehouse 301 is on arbor 1, the other end of mowing knife storehouse 301, the card slot that is used for installing mowing blade 302 is seted up to mowing knife storehouse 301 one end of keeping away from arbor 1 promptly, mowing blade 302 pegs graft in the card slot, through bolt fixed connection between mowing blade 302 and mowing knife storehouse 301. The mowing blade 302 is arranged in an arc shape, the mowing blade 302 is made of stainless steel, a hard alloy wear-resistant corrosion-resistant coating is sprayed on the surface of the mowing blade 302, and the thickness of the coating is 1.5 mm. The mowing knife magazine 301 is disposed obliquely, and accordingly, the mowing knife 3 is also disposed obliquely. The arrangement of the cutting knife layers 2 enables the cutting knife to directly crush weeds, and the crushed weeds can be directly supplied to the land as fertilizer; the arrangement of the coating on the mowing knife 3 improves the service life of the mowing knife 3.

The cutter shaft 1 between the adjacent cutter layers 2 is fixedly connected with a rotary blade 4, and the rotary blade 4 is spirally arranged along the cutter shaft 1. When the mowing blade 302 is used for smashing weeds, part of the weeds can be wound on the cutter shaft 1, so that the normal operation of the mowing blade is influenced, and the wound weeds must be manually removed; through setting up the rotary blade 4, when longer weeds are not smashed by the grass cutter 3 and are close to arbor 1, rotary blade 4 cuts it off, has reduced the winding of weeds on arbor 1, has improved work efficiency.

The bottom of arbor 1 detachably is connected with the connecting plate 6 of level setting, and the bottom fixedly connected with weeding sword device of connecting plate 6. Weeding knife tackle includes a plurality of weeding tool magazines 7, and the one end fixed connection of weeding tool magazine 7 has seted up the mounting groove in the bottom of connecting plate 6, the other end of weeding tool magazine 7, and it has weeding blade 8 to peg graft in the mounting groove, through bolt fixed connection between weeding blade 8 and the weeding tool magazine 7.

A plurality of weeding tool magazines 7 are arranged at intervals along the circumferential direction of the connecting plate 6; the weeding blades 8 are arranged in a curved arc shape, the end parts of the weeding blades 8 are hook-shaped structures which are obliquely and upwards arranged, and the hook-shaped structures are outwards arranged. The conventional cutter only cuts weeds exposed above soil, the roots of the weeds cannot be removed, and the weeding blades 8 loosen the soil on one hand and enlarge gaps among soil particles, so that the respiration of plant root cells is increased, the absorption of mineral elements by the plant roots is promoted, and the growth of plants is promoted; on the other hand, the weeding blades 8 turn out the roots of the weeds while loosening the soil, and directly pull up the weeds with roots, so that the weeds are prevented from absorbing nutrition in the soil and influencing the growth of other plants. The periphery fixedly connected with of

weeding tool magazine

7 and 8 junctions of weeding blade strengthens cover 10 to improve the structural stability of 8 devices of weeding blade, prolong the life of cutting knife.

Furthermore, the weeding blade 8 is fixedly connected with the spiral blade 9 along the extending direction, the soil loosened by the weeding blade 8 still has some caked soil, the caked soil is broken by the spiral blade 9 to be more refined, and the refined soil is further loosened. In addition, the spiral blade 9 has a certain crushing function on the roots of the weeds turned out by the weeding blade 8, the roots of the crushed weeds have no vitality at all, and the roots can be directly supplied to soil as fertilizer of the soil.

When the weed-cutting machine is used, the corresponding motor (the cutter shaft 1 is in transmission connection with the motor) drives the cutter shaft 1 to rotate, the grass-cutting knife 3 crushes stems and leaves of weeds, the rotary blade 4 crushes the weeds which are not crushed by the grass-cutting knife 3 and are close to the cutter shaft 1, and the weeds are prevented from winding the cutter shaft 1; meanwhile, the weeding blades 8 loosen the soil and pull out the roots of the weeds, and the spiral blades 9 refine the caked soil and crush the roots of the weeds.

The above embodiments are not intended to limit the shape, material, structure, etc. of the present invention in any form, and all of the technical matters of the present invention belong to the protection scope of the present invention to any simple modification, equivalent change and modification of the above embodiments.
