Abstract

The utility model provides a weeding rope structure for a weeding machine, and particularly relates to a weeding rope formed by connecting a steel bar with a clamping head through a steel cable, so the weeding rope can be arranged in a weeding disc through the clamping head, the outwards extending steel bar has the characteristic of swinging capability through the steel cable connection, and the collision buffer performance can be provided in the high-speed rotation weeding process.

Description

The weeding rope structure of weeder

Technical field

The utility model is a kind of weeding rope structure of weeder, should be mainly with a clip head, to link steel bar via cable wire to be formed except straw rope, urgees to make the steel bar except straw rope under High Rotation Speed, to break apart by chopping weeds, and is absorbed impact and cushioned by cable wire.

Background technology

In visible weeder structure on the market, mainly to be divided into utilizing weeding knife or removing two kinds of different structures of straw rope, although weeding knife is well suited for long-time use and does not need to change, but because weeding knife is to belong to firm material to have powerful destructive power, not only the process of weeding easily strike stone and occur that weeding knife comes off or the dangerous situation that flies out of rupturing (not only for the dangerous property of user, for passerby, also has lethality), also easily there is to use the unexpected problem being hurt, so be still with weeding rope structure and be subject to popular favor with regard to main flow on the market.

Yet, except the weeding principle of straw rope (as shown in Figure 1) be with pliable and tough material except straw rope is under the high speed rotary motion by weeding disk, make to form shear action except straw rope is positioned at weeding disk outer end, so can form friction in the process contacting with weeds, cutting force, smoothly weeds are broken apart by chopping and reached the object (therefore except the abrasion speed of straw rope is also very fast) of weeding, although it can be by causing danger property except the distortion cushioning effect of straw rope and not when touching the lump such as stone, but because touching the acute angle of foreign matter, cut disconnected except straw rope is unavoidable, cause the problem that straw rope ruptures often and must change of removing, so easily have influence on the efficiency of weeding and increase weeding cost.

The utility model people is in view of above-mentioned every shortcoming, dark, feel that although the existing weeder except straw rope formula has higher safety, but durability is but obvious deficiency, therefore then with it, be engaged in for many years the experience of Specialty Design weeder, actively research and development improvement, under the discretion of each side's condition is considered, start out the composition of this structure finally, can solve existing every problem completely.

Utility model content

The utility model is a kind of weeding rope structure of weeder, should to link steel bar after the fixed cable wire of a clip head, be formed except straw rope, to can be arranged in weeding disk via clip head, make extended steel bar there is swingable feature by the link of cable wire, therefore after enforcement, can provide following usefulness:

Because weeding rope device of the present utility model is after weeding disk, it is the steel bar design that exposes outside cable wire and link, therefore steel bar not only can be driven by the High Rotation Speed of weeding disk, and the steel bar of firm material more can the link design by cable wire have the buffering usefulness (cable wire can in stressed rear generation flexural deformation) that absorbs impact, so can smoothly weeds be broken apart by chopping with its friction, cutting force by the steel bar under High Rotation Speed when implementing, and because the high rigidity cutting force of steel bar more can break apart by chopping weeds easily, and then promote operating efficiency.Moreover, once steel bar, strike stone or the hard thing in weeds, because steel bar is to link via cable wire the design that, so can being provided via the flexural deformation of cable wire when steel bar strikes bar, buffering absorbs its power, can't occur foreign matter to clash into the dangerous problem fly out, therefore of the present utility model except straw rope not only durable but also safety is high.

Accompanying drawing explanation

For making auditor can really understand the function and benefit that structure of the present utility model forms and can reach, below in conjunction with accompanying drawing, enumerate embodiment, introduce in detail explanation as after, wherein:

Fig. 1 is existing structure figure.

Fig. 2 is structure chart of the present utility model.

Fig. 3 is composition state diagram of the present utility model.

Fig. 4 is enforcement schematic diagram of the present utility model.

Embodiment

The utility model is a kind of weeding rope structure of weeder, should by one, can fasten in the clip head 11 of weeding disk 10 pilot holes 101 and be formed (as shown in Figure 2 and Figure 3) via cable wire 12 link steel bars 13 except straw rope 1, the short cable wire 12 that makes extends weeding disk 10 outsides and links outward steel bar 13.

Known by the above-mentioned structural design except straw rope 1, via weeding disk 10, be installed with except straw rope 1 be the part that exposes outside cable wire 12 and steel bar 13, and High Rotation Speed that can be by weeding disk 10 except straw rope 1, centrifugal force are to produce shear action, therefore in the process of weeding, just can the weeds that touch be broken apart by chopping smoothly with friction, the cutting force of steel bar 13, and because the high rigidity speciality of steel bar 13 more can be brought into play preferably cutting force, and then promote the operating efficiency of weeding, weeding speed can significantly be improved and reduce human cost.

Moreover, in weeds heap, have unavoidably the problem that stone and various foreign matter exist, and when the utility model strikes foreign matter except the steel bar 13 of straw rope 1, because the steel bar 13 being exposed at outward outside weeding disk 10 is (partial-length of cable wire 12 is outer being exposed at outside weeding disk 10) that link via cable wire 12, therefore when clashing into generation, can cause immediately the diastrophic cushioning effect of cable wire 12 (as shown in Figure 4), to absorb, clash into power, so foreign matter can't be clashed into when steel bar 13 strikes foreign matter and fly out, (only can make cable wire 12 distortion along the external form of foreign matter, make steel bar 13 inswept along foreign matter.If there is no cable wire 12 between steel bar 13 and clip head 11, after steel bar 13 strikes foreign matter, will bend distortion and damage shell), can not cause danger completely, so the utility model except the safety of straw rope 1 high.

So known, the structural design of steel bars 13 that links via cable wire 12 with a clip head 11 except straw rope 1 of the present utility model, not only can promote herbicidal effect by the setting of steel bar 13, and the abrasion speed of steel bar 13 is extremely slow, there is long perfomance life, add the characteristic that buffering usefulness that cable wire 12 provides can be absorbed for impact, thus have again good safety concurrently, therefore propose utility application in accordance with the law.

Claims (1)

1. a weeding rope structure for weeder, is characterized in that, should by one, can fasten in the clip head of weeding disk pilot hole and be formed via cable wire link steel bar except straw rope, makes cable wire extend weeding disk outside and link outward steel bar.
