Abstract
The invention discloses a dry-land cutter used for a gasoline engine type minitype tiller, comprising a cutter body and a cutter handle, wherein the cutter handle is provided with two through holes, the center distance of the two through holes is 30-40mm, the length of the cutter handle is 50-70mm, the width is 20-30mm, and the thickness is 4.5-5.5mm. In the dry-land cutter, certain key parameters of the cutter handle are changed, thus the weight of the dry-land cutter is effectively lightened, and the load of the dry-land cutter is reduced, so that the load of the dry-land cutter is matched with the output power of a gasoline engine; in addition, the dry-land cutter is matched with the gasoline engine type minitype tiller for use so as to guarantee the service life of the gasoline engine; meanwhile, the consumption amount of raw materials for producing cutters is reduced; and the production cost is lowered.
Description
Technical field
The invention belongs to a kind of mini-size tillage machine cutter, relate in particular to a kind of nonirrigated farmland cutter that is used for the gasoline engine model mini-size tillage machine.
Background technology
As everyone knows, mini-size tillage machine mainly contains two types, and a kind of is diesel version, and it is power with the diesel engine, and this type mini-size tillage machine can the farming nonirrigated farmland after supporting nonirrigated farmland cutter is installed.Said supporting diesel version nonirrigated farmland cutter comprises cutter hub and handle of a knife, on handle of a knife, has two manholes, and the nonirrigated farmland cutter is installed on the cutterhead through these two through holes, and the centre-to-centre spacing of two through hole is about 70mm; The length of said handle of a knife is 100mm, and width is 18mm, and thickness is 6mm.Second kind is gasoline engine model, and it is power with the gasoline engine, and the power output of gasoline engine is littler than diesel engine.At present, the gasoline engine model mini-size tillage machine does not have supporting cutter, generally all is to use diesel version nonirrigated farmland cutter.Because length, width, thickness and the through hole centre-to-centre spacing etc. of nonirrigated farmland cutter handle of a knife directly influence the weight of cutter, become the key factor of decision cutter load size.Because diesel version nonirrigated farmland cutter aims at the supporting design of diesel engine; So the load size of nonirrigated farmland cutter just is complementary with the diesel engine power output; Again because the power output of diesel engine is bigger than gasoline engine, thereby gasoline engine and diesel version nonirrigated farmland cutter be not complementary, and it is bigger that mini-size tillage machine is used behind the cutter of diesel version nonirrigated farmland the load of gasoline engine; Power consumption is big, so just causes significantly shorten the service life of gasoline engine.In addition,, increased raw-material consumption on the one hand, increased production cost because length, width, thickness and the through hole centre-to-centre spacing of nonirrigated farmland cutter handle of a knife are all excessive; Make the installation fixing of nonirrigated farmland cutter relatively poor on the other hand again, hard thing handle of a knife is prone to break if work the time runs into stone etc. suddenly, thereby cutter is scrapped.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of nonirrigated farmland cutter that is used for the gasoline engine model mini-size tillage machine, so that be complementary with the power output of gasoline engine.
Technical scheme of the present invention is following: a kind of nonirrigated farmland cutter that is used for the gasoline engine model mini-size tillage machine, comprise cutter hub and handle of a knife, and on handle of a knife, have two through holes, its key is: the centre-to-centre spacing of said two through holes is 30～40mm; The length of said handle of a knife is 50～70 mm, and width is 20～30 mm, and thickness is 4.5～5.5 mm.
The present invention keeps Knife handle structure constant on the basis of conventional art, has just changed the centre-to-centre spacing of two through holes on the handle of a knife dexterously, makes the centre-to-centre spacing of two through hole become 30～40mm, has so just guaranteed the installation fixing of cutter reliably; Correspondingly adjusted simultaneously the length of handle of a knife, made the length of handle of a knife become 50～70 mm, and be 20～30 mm the width adjustment of handle of a knife; The thickness of handle of a knife is adjusted into 4.5～5.5 mm, has effectively reduced the weight of cutter so on the one hand, has reduced the load of cutter; The load of this nonirrigated farmland cutter and the power output of gasoline engine are complementary; Thereby reliably guarantee the service life of gasoline engine, reduced raw-material consumption on the other hand, reduced production cost.
Preferred scheme is that the centre-to-centre spacing of said two through holes is 35mm, so just can guarantee the installation fixing of cutter and cutterhead reliably.
The length of said handle of a knife is 60mm, and the length scale of handle of a knife is moderate, can effectively reduce the load of cutter, can guarantee the structural strength of handle of a knife again.
As optimization, the width of said handle of a knife is 25 mm.
The thickness of said handle of a knife is 5mm, and above structure helps further to alleviate the weight of cutter under the prerequisite that guarantees structural strength, further reduce the load of cutter.
Beneficial effect: the present invention is through changing several key parameters of handle of a knife; Effectively reduce the weight of nonirrigated farmland cutter, reduced the load of nonirrigated farmland cutter, the power output of itself and gasoline engine is complementary; And with this nonirrigated farmland cutter and the supporting use of gasoline engine model mini-size tillage machine; Thereby effectively guarantee the service life of gasoline engine, and reduced the raw materials consumption amount of producing cutter simultaneously, reduced production cost.

Fig. 2 is the end view of Fig. 1;
Fig. 3 is the front view of embodiment 2;
Fig. 4 is the end view of Fig. 3.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
Like Fig. 1, shown in 2, the present invention is made up of cutter hub 1 and handle of a knife 2, the head end decurvation of cutter hub 1 wherein, and the concrete structure of this cutter hub 1 is identical with prior art, does not do at this and gives unnecessary details.The tail end of said cutter hub 1 is formed with handle of a knife 2, and this handle of a knife 2 is a linear structure, and the length B of handle of a knife 2 is 50～70 mm, and in the present embodiment, the length B of handle of a knife 2 is 60mm.The width C of said handle of a knife 2 is 20～30 mm, and in the present embodiment, the width C of handle of a knife 2 is 25 mm.The thickness D of said handle of a knife 2 is 4.5～5.5 mm.In the present embodiment, the thickness D of handle of a knife 2 is 5mm.
Can find out that like Fig. 1,2 on above-mentioned handle of a knife 2, have two manholes 3, this nonirrigated farmland cutter is installed on the cutterhead (not drawing among the figure) through these two through holes 3, and the centre-to-centre spacing A of two through holes 3 is 30～40mm; In the present embodiment, the centre-to-centre spacing A of two through hole 3 is 35mm.
