Abstract

The utility model provides a kind of New Kind of Hob structure of mower, belongs to mower technical field.It solving existing mower uses rear blade to have part wears for a long time, is formed and starts too high and touch the problem of stationary knife.This hob-cutter structure comprises cutter shaft, knife rest and roll blade, cutter shaft passes knife rest successively and is connected with knife rest, multi-disc roll blade is arranged on the outer rim place of each knife rest twist, each roll blade all has origin or beginning and tail end, knife rest is also provided with the company's blade connecting adjacent two roll blade origin or beginnings and tail end, respectively connecting blade is the outer rim place that reverse acting spiral shape is arranged on each knife rest, adjacent two roll blades and even blade form " Z " character form structure, take cutter shaft as axle center, the blade of roll blade and even blade is all on identical radius.This device can make stationary knife be attached to roll blade and connect on the blade of blade to slide, and avoids the high low head of blade to produce beating of stationary knife, mower can be made under blade state of wear also to there will not be Caton phenomenon.

Description

A kind of New Kind of Hob structure of mower

Technical field

The utility model belongs to mower technical field, particularly a kind of New Kind of Hob structure of mower.

Background technology

Along with society and expanding economy, the environmental consciousness of people is also more and more stronger, and our life that what meadow, lawn was a large amount of enter, therefore mower have also been obtained and uses widely.The cutter of mower is divided into hobboing cutter and stationary knife.Grass is rolled by hobboing cutter, weeds are cut off by the blade on stationary knife, and the relative hobboing cutter of stationary knife can realize the object automatically regulating otch, if patent announcement number is CN203537851U, namely the utility model of a kind of Novel grass cutter by name is disclosed stationary knife and can directly be abutted on hobboing cutter by spring, and forms the structure of the better otch of compactness.And the hobboing cutter of prior art is generally patent announcement CN202799651U is called the same structure of the hobboing cutter assembly of mower, this hobboing cutter assembly comprises a cutter shaft and multi-disc roll blade, roll blade is arranged on the outer rim place of each knife rest twist, roll blade take cutter shaft as axle center annular array, and every sheet roll blade includes starts and tail end.Blade has part wears after a long time use, form too high problem of starting, and stationary knife is strained at by spring, and therefore each starting when touching stationary knife can have the too closely collision produced at every turn, often produces the phenomenon that card pauses during work.

Summary of the invention

The purpose of this utility model is the problem for existing hobboing cutter and stationary knife mismate, and proposes a kind of New Kind of Hob structure making blade head and the tail echo circulation.

The purpose of this utility model realizes by following technical proposal: a kind of New Kind of Hob structure of mower, comprise cutter shaft, at least two knife rests and multi-disc roll blade, cutter shaft passes knife rest successively and is connected with knife rest, above-mentioned multi-disc roll blade is arranged on the outer rim place of each knife rest twist, it is characterized in that, described each roll blade all has origin or beginning and tail end, knife rest is also provided with the company's blade connecting adjacent two roll blade origin or beginnings and tail end, respectively connecting blade is the outer rim place that reverse acting spiral shape is arranged on each knife rest, adjacent two roll blades and even blade form " Z " character form structure, take cutter shaft as axle center, the blade of above-mentioned roll blade and even blade is all on identical radius.

When roll blade with when connecting blade abrasion, stationary knife fluctuates along the line with " Z " word, and each end of roll blade and even blade all can not form rum point.

In the New Kind of Hob structure of above-mentioned a kind of mower, described roll blade origin or beginning and tail end all with connect the two ends of blade and to be welded as a whole formula structure.

In the New Kind of Hob structure of above-mentioned a kind of mower, described knife rest in the form of sheets and arrange perpendicular to cutter shaft.

In the New Kind of Hob structure of above-mentioned a kind of mower, described each knife rest spaced set.

Compared with prior art, this device can make stationary knife be attached to roll blade and connect on the blade of blade to slide, and avoids the high low head of blade to produce beating of stationary knife, mower can be made under blade state of wear also to there will not be Caton phenomenon.

Accompanying drawing explanation

Fig. 1 is the rotating knife structural representation of this mower;

In figure, 1, knife rest; 2, cutter shaft; 3, stationary knife; 4, roll blade; 4a, origin or beginning; 4b, tail end; 5, blade is connected.

Embodiment

Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.

As shown in Figure 1, the rotating knife structure of this mower comprises cutter shaft 2, three knife rests 1 and multi-disc roll blade 4, equidistant interting is located on cutter shaft 2 three knife rests 1 successively, multi-disc roll blade 4 is arranged on the outer rim place of each knife rest 1 twist, monolithic roll blade 4 comprises origin or beginning 4a and tail end 4b, be connected with a slice at the origin or beginning 4a of adjacent two panels roll blade 4 and tail end 4b place and connect blade 5, respectively connect blade 5 is arranged on each knife rest 1 outer rim place in reverse acting spiral shape, adjacent two roll blades 4 and even blade 5 form " Z " character form structure, described roll blade 4 and even blade 5 are all welded on knife rest 1, roll blade 4 origin or beginning 4a and tail end 4b all with connect the two ends of blade 5 and to be welded as a whole formula structure, with cutter shaft 2 for axle center, the blade of above-mentioned roll blade 4 and even blade 5 is all on identical radius.

When cutter shaft 2 rolls, stationary knife 3 is sticked at roll blade 4 and connects on the blade of blade 5, and when roll blade 4 is with when even blade 5 has wearing and tearing, stationary knife 3 is with " Z " wordline floating motion, and roll blade 4 all can not form rum point with each end connecting blade 5.

Should be appreciated that, in claims of the present utility model, specification, all " comprising ... " is all interpreted as open implication, and namely its implication is equal to " at least containing ... ", and should not be construed as enclosed implication, namely its implication should not be construed " only comprising ... ".

Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
