Abstract

The utility model relates to a multifunctional rotary cultivator which is composed of a drive housing, a main beam, vertical plates, a rotary cultivation shaft and a rotary cultivation blade. The utility model is characterized in that a group of small flanges are fixed on the rotary cultivation shaft, and a stubble-cleaning cutter is fixed on a small flange through a split type large flange; one lateral plate is respectively fixed on each of the vertical plates arranged on both sides of a rotary cultivator, a front cross beam and a rear cross beam are respectively bridge on both ends of each lateral plate, a group of adjustable break shovels are fixed on each front cross beam, and a group of adjustable tie ridgers are fixed on each rear cross beam. The utility model not only can carry out single cultivation operation on a field, such as rotary cultivation, stubble cleaning, ridging, etc., but also can carry out synchronous cultivation operation, such as scarification, rotary cultivation and ridging or scarification, stubble cleaning and ridging.

Description

Multifunction rotavator

The utility model relates to a kind of agricultural rotovator, particularly multifunction rotavator, belongs to a kind of improvement of rotovator.

At present, before farmland sowing, all need the soil carried out field farming of several steps such as rotary tillage, stubble-cleaning, ridging, but the rotovator function singleness that sell in market, want to carry out comprehensive farming and also need to purchase separately miscellaneous equipment, so both increased the expense of procuring equipment, need extend again the time of operation step by step, strengthen field farming cost, make the peasant feel inconvenience.

The purpose of this utility model provides a kind of multifunction rotavator, and it can not only carry out field individual event farming such as rotary tillage, stubble-cleaning, ridging, and can also loosen the soil, rotary tillage, ridging or loosen the soil, stubble-cleaning, two synchronous farming of ridging.

The purpose of this utility model is achieved in that the multifunction rotavator of being made up of transmission case, girder, riser, rotary tillage shaft and rotary blade, one group of small flange plate is fixed on the rotary tillage shaft, the stubble-cleaning cutter is fixed on the small flange plate by split type big flange, also fix a side plate on the riser of rotovator both sides respectively, former and later two crossbeams are connected across the two ends of side plate respectively, one group of adjustable break shovel is fixed on the front beam, and one group of adjustable tie ridger is fixed on the rear cross beam.

The utlity model has characteristics simple in structure, a tractor serves several purposes, several parts of being convenient to load and unload on former rotovator, have only been increased, though cost increases few, but can finish rotary tillage, stubble-cleaning, loosen the soil, multiple synchronous farming such as ridging, brought convenience to farm work.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a concrete structure schematic diagram of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

In Fig. 1,2, the multifunction rotavator that constitutes by transmission case 15, girder 10, riser 11, rotary tillage shaft 5 and rotary blade, the small flange plate 12 of eight band screws is welded on respectively on the rotary tillage shaft 5 between the rotary blade trousers 13, and the split type big flange 4 usefulness screws that stubble-cleaning cutter 6 is formed by two semi-circular plates are separately fixed on the small flange plate 12; On riser 11, also be screwed respectively and connect a side plate 9; Two end faces of

crossbeam

3,8 all weld the connecting plate 14 of a band screw,

crossbeam

3,8 is fixed on the two ends of side plate 9,16 by connecting plate 14 usefulness screw cross-over connections, three break shovels 1 are screwed on front beam 3 by iron card 2, iron card 2 can move on crossbeam 3, break shovel 1 can move up and down in iron card 2, is used for regulating the spacing of break shovel 1 and the degree of depth of loosening the soil.Three tie ridgers 7 are screwed on rear cross beam 8 by iron card 2 equally, and tie ridger 7 can adjust spacing equally and the ridge is dark.

During work, multifunction rotavator is connected on the oil pressure control lever at tractor rear portion, power transmission shaft on the transmission case 15 is connected with the tractor dynamic power axle by universal drive shaft, begin operation after adjusting the spacing of break shovel 1 and tie ridger 7 and height, at this moment break shovel 1 is soft with soil, rotary tillage shaft 5 rotates under the driving of transmission case 15, driving stubble-cleaning cutter 6 by

flange

12,4 rotates, the root stubble that stays after the crops harvestings smashed resigns from office and return home, simultaneously tie ridger 7 subsequently time trench culture ridge finish loosen the soil, stubble-cleaning, the synchronous farming of ridging.In the time need not beating batch, stubble-cleaning cutter 6 unloads from small flange plate 12 together with big flange 4, and rotary blade inserts in the rotary blade trousers 13 on the rotary tillage shaft 5 and uses screw lock, at this moment just can loosen the soil, rotary tillage and ridging operation.

Claims

1, a kind of multifunction rotavator of forming by transmission case, girder, riser, rotary tillage shaft and rotary blade, it is characterized in that: one group of small flange plate is fixed on the rotary tillage shaft, the stubble-cleaning cutter is fixed on the small flange plate by split type big flange, also fix a side plate on the riser of rotovator both sides respectively, former and later two crossbeams are connected across the two ends of side plate respectively, one group of adjustable break shovel is fixed on the front beam, and one group of adjustable tie ridger is fixed on the rear cross beam.

2, multifunction rotavator according to claim 1 is characterized in that: one group of eight small flange plate are weldingly fixed on respectively on the rotary tillage shaft between the rotary blade trousers.
