Abstract
The invention relates to an internal reaming type anti-drag coulter of a rotary cultivator. The internal reaming type anti-drag coulter comprises a coulter shaft and a coulter blade on the coulter shaft, wherein the coulter blade comprises positive coulter blades and negative coulter blades, and the positive coulter blades and the negative coulter blades are symmetrically mounted on the coulter shaft; positive bent parts and negative bent parts are respectively arranged at the outer ends of the positive coulter blades and the outer ends of the negative coulter blades and bent towards the outer end of the coulter shaft; an internal reamer, which is of a disk-shaped structure, is mounted on the coulter shaft between the positive coulter blades and the negative coulter blades; the internal reamer is provided with cutting teeth which are symmetrically distributed around the center of the internal reamer and are alternately arranged; first anti-drag holes are formed in the positive coulter blades; first cutting teeth are formed in the concave surface sides of the positive bent parts of the positive coulter blades; second anti-drag holes are formed in the negative coulter blades; second cutting teeth are formed in the concave surface sides of the negative bent parts of the negative coulter blades; third anti-drag holes are formed in the cutting teeth. The internal reaming type anti-drag coulter has the characteristics of being high in rotary cultivation efficiency and good in effect.
Description
Technical field
The present invention relates to technical field of agricultural machinery, especially a kind of hand-held rotary cultivator.
Background technology
Rotary cultivator is the cultivation machinery completing to plough, harrow operation with tractor.Because of its have hack ability strong,
The features such as cultivated rear earth's surface is smooth, and be widely used.
The interior hinge formula drag reduction colter of rotary cultivator of the prior art, the structure design of its colter is unreasonable, rotary tillage
Inefficient, poor effect.
Summary of the invention
The applicant is for the above-mentioned medium shortcoming of existing production technology, it is provided that a kind of rational in infrastructure, work efficiency
The interior hinge formula drag reduction colter of high rotary cultivator.
The technical solution adopted in the present invention is as follows:
The interior hinge formula drag reduction colter of a kind of rotary cultivator, including installing colter sheet, described colter on cutter shaft, cutter shaft
Sheet includes positive colter sheet and anti-colter sheet, the outer end of positive colter sheet and the anti-colter sheet being symmetrically arranged on cutter shaft
Outer end be respectively provided with to cutter shaft outer end bending positive bending part and opisthotonos turn of bilge；Described positive colter sheet and anti-plough
Being provided with interior reamer on cutter shaft between blade, interior reamer is disc-shaped structure, and its band is related to the wherein heart pair
Claim distribution spaced cutting teeth；
With the first drag reduction hole on described positive colter sheet, the concave side of its positive bending part is with the first cutting；
With the second drag reduction hole on described anti-colter sheet, the concave side of its opisthotonos turn of bilge is with the second cutting；
With the 3rd drag reduction hole on described cutting teeth.
Beneficial effects of the present invention is as follows:
The present invention colter sheet by forward and reverse direction, it is achieved forward and reverse direction rotary tillage, its efficiency is high, effect
Good；Interior reamer is set on cutter shaft, the earth opened through colter sheet is carried out secondary rubbing, it is to avoid bulk earth
Exist, improve rotary tillage efficiency；The resistance between colter sheet and interior reamer and clod is reduced by drag reduction hole, logical
Cross cutting and improve the cutting dynamics to clod, thus improve rotary tillage efficiency and effect further.
Accompanying drawing explanation
Fig. 1 is the three-dimensional structure diagram of the present invention.
Wherein: 1, cutter shaft；2, positive colter sheet；21, positive bending part；22, the first cutting；23, first
Drag reduction hole；3, anti-colter sheet；31, opisthotonos turn of bilge；32, the second cutting；33, the second drag reduction hole；4、
Interior reamer；41, cutting teeth；42, the 3rd drag reduction hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described.
As it is shown in figure 1, the interior hinge formula drag reduction colter of the rotary cultivator of the present embodiment, including cutter shaft 1, cutter shaft 1
Upper installation colter sheet, colter sheet includes the positive colter sheet 2 that is symmetrically arranged on cutter shaft 1 and anti-colter sheet 3,
Positive colter sheet 2 and anti-colter sheet 3 include three groups respectively；Outside the outer end of positive colter sheet 2 is with anti-colter sheet 3
End is respectively provided with the positive bending part 21 to the bending of cutter shaft 1 outer end and opisthotonos turn of bilge 31, and positive bending part 21 is with anti-
Bending part 31 bending dorsad；On positive cutter shaft 1 between colter sheet 2 and anti-colter sheet 3, interior reamer 4 is installed,
Interior reamer 4 is disc-shaped structure, and its band is related to that the wherein heart is symmetrical and spaced cutting teeth 41,
Cutting teeth 41 is traditionally arranged to be 4, and cutting teeth 41 sets counterclockwise or clockwise around the center of interior reamer 4
Put.
With the first drag reduction hole 23 on positive colter sheet 2, the concave side of its positive bending part 21 is with the first cutting
22；With the second drag reduction hole 33 on anti-colter sheet 3, the concave side of its opisthotonos turn of bilge 31 is with the second cutting
32；With the 3rd drag reduction hole 42 on cutting teeth 41.By the 23, second drag reduction hole 33, the first drag reduction hole and
3rd drag reduction hole 42 reduces the resistance between colter sheet and interior reamer and clod, by the first cutting 22,
Two cuttings 32 improve the cutting dynamics to clod, thus improve rotary tillage efficiency and effect.
The present invention colter sheet by forward and reverse direction, it is achieved forward and reverse direction rotary tillage, its efficiency is high, effect
Good；Interior reamer is set on cutter shaft, the earth opened through colter sheet is carried out secondary rubbing, it is to avoid bulk earth
Exist, improve rotary tillage efficiency；The resistance between colter sheet and interior reamer and clod is reduced by drag reduction hole, logical
Cross cutting and improve the cutting dynamics to clod, thus improve rotary tillage efficiency and effect further.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention is joined
See claim, within protection scope of the present invention, any type of amendment can be made.
