Abstract

The utility model provides a straw-burying rotary cultivator for paddy fields. The straw-burying rotary cultivator for paddy fields is characterized in that a straw-cutting vertical knife is welded on a straw-burying cross knife, and an ideal included angle of the straw-burying cross knife and a main shaft is 17.5 DEG; a straw-cutting bent knife is welded on three flanges, and a straw blocking plate is welded on the outer side of the welding part of the straw-cutting bent knife and the flanges. The utility model has the advantages of light weight, high efficiency, low oil consumption, long service life, low price, high reliability, etc.

Description

A kind of paddy-field grass-burying rotovator

The utility model relates to a kind of rotovator, paddy-field grass-burying rotovator particularly, and its model is the 1MGZ-69 type.

In the prior art, the agronomy of straw incorporation has progressively been used in " two summer " in some grain producing regions plantation operation and has been come, common practices is the disposable direct returning to farmland of whole rice bar after the results to be buried cover, the key of this technology is tightly to cover by ploughing the straw that will go back the field in whole ground, just can reach strengthen soil fertility and volume increase, efficiently, rob the effect in farming season.

Return the field The Application of Technology for promoting straw, agricultural machinery department is devoted to the exploitation improvement always and is applicable to that straw returns the matched farm tool that tillage operation is ploughed in field (paddy field) mechanization.Workers and peasants-12K hand tractor is the paddy field mechanized main force of ploughing whole ground, but its former supporting work tool rotovator, grass is incompatible to return the field ploughing operation at straw because of easily twining, afterwards, the matched farm tool 1BSQ-69 type paddy field driving harrow that development makes new advances returns operation on the field at straw, and it is good than rotovator to bury careless covering function, but the increase of going back to the field along with stalk, drive rake seem again bury aspect careless not ideal.

Developed 1MG-65 type paddy-field grass-burying rotovator afterwards, but this machine shortcoming is: the one, the facility quality is big, and the overload phenomenon generally appears in hand tractor during operation; Next is that these machine two ends easily twine grass even block, and causes overload even disorderly closedown; Be (600 yuan every) on the high side once more, the tractor driver is difficult for accepting, and promotes difficulty on a large scale.

The purpose of this utility model be intended to overcome the deficiencies in the prior art and provide that a kind of reasonable in design, novel structure, adaptability are strong, dependable performance, use is easy to maintenance, production efficiency is high, the tilling width tilling depth stable, plough the flat mud suede in field, back, meet agriculture requirement, have characteristics such as " savings of labor, save time, fuel-efficient, inexpensive, practicality " simultaneously, the paddy-field grass-burying rotovator of the paddy field straw directly returning to field of agriculture coideal.

The purpose of this utility model is achieved in that

A kind of paddy-field grass-burying rotovator, comprise main shaft 4, spline 5 and flange 3, it is characterized in that also comprising and bury careless horizontal cutter 1, chaffcutter upright cutter 2, chaffcutter tulwar 6 and grass guard 7, the upright cutter 2 of chaffcutter is welded on and buries on the careless horizontal cutter 1, bury careless horizontal cutter 1 and be welded on the chaffcutter tulwar 6, chaffcutter tulwar 6 is again on the welding flange 3, and two square grass guards 7 are welded on the outside of chaffcutter tulwar 6 and flange 3 welds at main shaft 4 two ends.

-describedly burying careless horizontal cutter 1 and have 10, the angle of itself and main shaft 4 is the best with 17.5 °.

The upright cutter 2 of-described chaffcutter is dislocatedly distributed and buries on the careless horizontal cutter 1 at 10, carries main shaft 4 to turning up.

-described chaffcutter tulwar has 20, and on two flange at main shaft 4 two ends each 5, install 10 on the flange at main shaft 4 middle parts, be all symmetrically and weld.

Below by drawings and Examples the utility model being done a step describes in detail:

Fig. 1 is that the master of the utility model structure looks schematic diagram

Fig. 2 is that schematic diagram is looked on the left side of the utility model structure

In Fig. 1, Fig. 2,1 for burying careless horizontal cutter, and 2 are the upright cutter of chaffcutter, and 3 is flange, and 4 is main shaft, and 5 is spline (standard type 6-34 * 28 * 6), and 6 is the chaffcutter tulwar, and 7 is grass guard.

During enforcement, except that main shaft, the complete machine material all adopts the 45# steel, through special thermal treatment, makes and buries careless horizontal cutter 1, and chaffcutter founds cutter 2, chaffcutter tulwar 6 and square grass guard 7.Chaffcutter stands being dislocatedly distributed of cutter: on 5 of close spline 5 one side horizontal cutter is welded 3,4,3,4,3 chaffcutters in proper order and found cutter, another side 5 horizontal cutter on, 4,3,4,3,4 chaffcutters of welding found cutter in proper order, note standing the knife back and main shaft to turning up, chaffcutter tulwar 6 is welded on 3 flange, each 5 at two ends, 10 of middle flange welding will be symmetrically.To bury careless horizontal cutter 1 is welded on the chaffcutter tulwar 6, the angle of noting horizontal cutter and main shaft preferably is adjusted into 17.5 °, this is optimal angle, respectively welds two square grass guards at last on two flange at main shaft two ends, and the position is in the weld outside of chaffcutter tulwar and flange.During use the standard spline 5 of spindle end is articulated on main force's output shaft of 12K series hand tractor, the hand drawing force drives the utility model by chain drive and rotates and carry out operation, can select 279 rev/mins or 184 rev/mins of two kinds of rotating speeds to adjust the rotary tillage degree of depth.

The technique effect that the utility model reaches is: one, the facility quality is light, more traditional facility Every light 4 kilograms; Two, operating efficiency height exceeds 0.3～0.5 mu/hour on traditional facility; Three, the operation oil consumption is low, 0.5 kilogram of the average every mu of low oil consumption of more traditional facility; Four, twine grass, It is few to hang grass, and average every mu the grass extension grass amount that twines only is 1/3 of traditional facility; Five, straw cutting Effective, the more traditional facility of cut-out rate improve 40%; Six, dependability height, wearability, Robustness is good, and be more than the twice of traditional facility service life; Seven, reasonable price easily is Wide farmers is accepted, and is convenient to apply on a large scale.
