Abstract

Disclosed is a no-tillage planter ditching knife with stubble breaking and weed throwing functions. The ditching knife comprises a knife handle and a knife body, wherein the knife body is fixedly connected to the knife handle in an inclined mode, two installment holes are formed in the lower portion of the knife handle, reinforcing ribs are arranged between the two installment holes, a knife blade is arranged on the arc-shaped side edge where the knife body and the knife handle are fixedly connected, and the included angle between the knife body and the knife handle ranges from 15 degrees to 25 degrees. The ditching knife can conveniently chop stubbles on the surface of earth, ditch, break soil, and throw sundries such as wound weeds, can achieve the purpose of stubble breaking, weed throwing and ditching at one time, is high in strength, smoothly works, and can meanwhile leave the stubbles on the surface of the earth, reserve water and soil moisture and prevent sand blown by the wind.

Description

No-tillage seeding machine is with the energy breaking and get rid of careless ditching knife

Technical field

The utility model belongs to agricultural mechanical field, relates to a kind of no-tillage seeding machine with the energy breaking and gets rid of careless ditching knife.

Background technology

At present, in the agricultural machinery farming cutter of China, mainly contain rotary blade and stubble-cleaning knife, the function of rotary blade is mainly to cut soil, get rid of soil, and in use, power attenuation is large, and cutter easily is wound around the weeds foreign material; The function of stubble-cleaning knife is mainly shallow plowing, breaking.After using these two kinds of cutter operations, soil and weeds mix often, have brought adverse influence for germination and the growth of sowing crop seed, and the easy evaporation of water in soil of soil, cause percentage of seedgermination low.Therefore, in conjunction with architectural characteristic and the function of these two kinds of cutters, newly design a kind of can breaking, get rid of the ditching knife of grass, high, the stable working of intensity not only, and can realize breaking, get rid of grass and break ground trench digging.

The utility model content

The purpose of this utility model be to provide no-tillage seeding machine a kind of simple in structure, safe and reliable with can breaking, get rid of the ditching knife of grass.

The technical solution of the utility model is: no-tillage seeding machine is with the energy breaking and get rid of careless ditching knife, comprising: handle of a knife, blade; Become inclination angle to be fixed on handle of a knife blade, be provided with two installing holes in the handle of a knife bottom, be provided with reinforcement between two installing holes, at blade and the affixed arc-shaped side edges of handle of a knife, be provided with blade.

The inclination angle that blade and handle of a knife form is 15-25 °.

The utility model can reach following good effect after adopting technique scheme: no-tillage seeding machine with can breaking, get rid of careless ditching knife and can shred easily earth's surface stubble, the hack of ditching, get rid of the weeds foreign material of winding.Can once realize breaking, get rid of grass, the purpose of trench digging, intensity is high, stable working, can stay earth's surface to stubble, the water-retaining effect sand-proof simultaneously.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.As shown in Fig. 1 ~ 4, no-tillage seeding machine with can breaking, get rid of the ditching knife of grass, mainly comprise: handle of a knife 2,

blade

5,5 one-tenth inclination alpha of blade are fixed on handle of a knife 2, be provided with two installing holes 1 in handle of a knife 2 bottoms, be provided with reinforcement 3 between two installing holes 1, the arc-shaped side edges affixed at blade 5 and handle of a knife 2 is provided with blade 4.

Blade 5 is 15-25 ° with the inclination alpha that handle of a knife 2 forms.

The version of foregoing description is two embodiment of ditching knife, and its citation form and operation principle are identical.

The material of cutter generally adopts steel alloy to make.Cutter is in when work, by two installing holes 1, is fixed on the cutter shaft upper rotary and level is advanced, and does the motion of rotation sliding cutting.Reinforcement 3 is arranged on handle of a knife 2, to guarantee cutter, enough intensity is arranged.Blade 45 buries gradually from handle of a knife 2 to blade, first cuts off the stubble of staying earth's surface, then cuts soil, then cuts off the root system in soil.In rotating process, utilize the inclination alpha of blade 5 and handle of a knife 2 that weeds foreign material and soil are cast aside, utilize the proportion of weeds foreign material and soil different from grass, the native separation in the process of casting aside, realize getting rid of the purpose of grass trench digging.
