Abstract

The utility model mainly provides a decomposable grass mowing line made of a decomposable material. The material can be polylactic acid (PLA, Polylactide) or polycaprolactone (PCL) orpolyvinyl alcohol (PVA). By matching with the section shape design of the mowing line and the spiral angle of an axial line of the mowing line, the utility model not only can cause the used mowing line to be effectively decomposed in a natural environment and eliminate the pollution of a common plastic mowing line to the environment, but also enhance the cutting capability of the mowing line by using the section shape design of the mowing line, simultaneously strengthens the cutting capability of the mowing line by using the spiral angle of the axial line of the mowing line, and reduces the wind resistance for the rotation of the mowing line, thus the utility model simultaneously has the functions of decomposing and strengthening the cutting capability.

Description

Decomposable glass cutting wires

Technical field

The utility model relates to a kind of decomposable glass cutting wires, particularly instigate and be used for the employed plastic cement glass cutting wires of mower, especially refer to a kind of with PLA (PLA, Polylactide) or polycaprolactone (PCL) or polyvinyl alcohol (PVA) as the glass cutting wires of material manufacturing, but after use environmental sound and glass cutting wires free of contamination natural decomposition.

Background technology

Existing mower is except the mowing iron plate of original use, glass cutting wires also gradually more and more users uses, but be to use general plastic material manufacturing mostly at existing glass cutting wires, under normal mowing situation, use, glass cutting wires can abrasion damage and keep somewhere in thick grass in the process of mowing, residing in the grassland soil gradually because plastic cement is can't natural decomposition corrupt and absorbed by soil, resides in the pollution that general plastic cement glass cutting wires in the grassland soil will cause soil.

Common glass cutting wires is considered because of manufacturing technology and manufacturing cost, be mainly circular cross section, and do not have the axis of spiral angle, because the glass cutting wires surface is slick and sly, it mainly relies on the kinetic energy of the grass-cutting head glass cutting wires that high speed rotating offers of mower to cut grass blade.

Therefore how solving glass cutting wires residues in pollution problems in the soil, and the mowing ability of strengthening glass cutting wires again, then is glass cutting wires manufacturer urgent problem.

Summary of the invention

Because the problem that above-mentioned environmental pollution and cutting power are strengthened is badly in need of solving, it is a kind of with PLA (PLA that the utility model mainly provides, Polylactide) or polycaprolactone (PCL) or polyvinyl alcohol (PVA) as the decomposable glass cutting wires of material manufacturing, in soil, understanding natural decomposition after the use, environmental sound and pollution-free; While and advanced manufacture method and the fabrication schedule of collocation, the section configuration of glass cutting wires is improved, provide glass cutting wires to have non-circular section, section with corner cut can be strengthened cutting function, and simultaneously with glass cutting wires spiral in addition, strengthen the cutting power of glass cutting wires and the windage that reduces the glass cutting wires rotation again, except the effect that used glass cutting wires decomposes in natural environment is provided, and utilize the section configuration of glass cutting wires and the cutting power that the helix body is strengthened glass cutting wires, solve the use shortcoming of glass cutting wires.

In order to achieve the above object, the utility model provides a kind of decomposable glass cutting wires, but its glass cutting wires is the non-circular section glass cutting wires of being made by decomposing material.

Compared with prior art, the beneficial effects of the utility model are:

Of the present utility modelly provide a kind of decomposable glass cutting wires, described glass cutting wires can reduce the pollution to soil, to reach the target of environmental protection in natural decomposition after the use in grassland soil.

The utility model provides a kind of decomposable glass cutting wires, but it is to make glass cutting wires with decomposing material, employed material can be selected PLA (PLA for use, Polylactide) or polycaprolactone (PCL) or polyvinyl alcohol (PVA), itself promptly be to add that with the natural organic such as grain petrochemical materials makes, so also can reduce situation simultaneously to the dependence of oil.

The utility model provides a kind of decomposable glass cutting wires, and the design that it is strengthened cutting power and reduces windage also can reduce the energy resource consumption of mower, and is helpful to energy savings and minimizing global warming.

Embodiment

Below in conjunction with accompanying drawing, be described in more detail with other technical characterictic and advantage the utility model is above-mentioned.

Feature of the present utility model and advantage please refer to the embodiment of Fig. 1 to Fig. 4, a kind of decomposable glass cutting wires provided by the utility model, as shown in Figure 1, but be to make glass cutting wires with decomposing material, employed material can be selected PLA (PLA for use, Polylactide) or polycaprolactone (PCL) or polyvinyl alcohol (PVA), be installed on the grass-cutting head of mower, when on the meadow, cutting grass blade, glass cutting wires 10 can be because of the cutting wearing and tearing, perhaps rupture, in grassland soil, be not easy inspection and pick up recovery because volume is little because cutting to hard thing; But the utility model can decompose in grassland soil gradually with the glass cutting wires of decomposing material manufacturing, can contaminated soil, reduce infringement to environment.

The utility model is simultaneously with the section configuration of glass cutting wires Change In Design in addition; provide glass cutting wires to have non-circular section; as shown in Figures 1 to 4; section with corner cut 11 can utilize corner cut 11 to strengthen the function of cutting grass blade; simultaneously with glass cutting wires spiral in addition; in the time of can strengthening the cutting power of glass cutting wires again and utilize spiral with glass cutting wires 10 rotations; air-flow can flow fast along conveyor screw; effectively windage is reduced; reduce the energy resource consumption of mower; further save the energy, promote protection environment effect of the present utility model again.

Comprehensively above-mentioned, " decomposable glass cutting wires " disclosed in the utility model, but provide a kind of glass cutting wires made from the natural decomposition material 10, have the section of corner cut 11 and spiral in addition, by decomposable material, allow used glass cutting wires 10 can be in soil natural decomposition, reach non-staining effect, the corner cut 11 and the helix body of its section then provides to be strengthened the glass cutting wires cutting performance and reduces glass cutting wires windage loading coefficient, lower the multi-functional of mower energy pin consumption, and obtain the high decomposable glass cutting wires of a convenient utility, make whole really tool industrial applicability and innovation benefit.

More than explanation is just illustrative for the utility model; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection domain of the present utility model.
