Description
Technical field:
The utility model relates to a kind of cutter shaft assembly of compound rotovator, belongs to agriculture rotary tillage mechanical fitting technical field.
Background technology:
Rotovator is a kind of tillage implement that China's immediate development is got up, and the rotavator knife axle assembly is one of most important parts of rotovator.The cutter shaft assembly of rotovator is installed in by minor axis and bearing block on the frame of rotovator, and rotary blade is installed on the cutter shaft by tool rest, and tool rest adopts cross symmetry to install on cutter shaft; It integrates cultivated, harrows, and can reach with farm cattle plough, rake work effect several times the rotary tillage operation in farmland.Present rotovator is limit because of the version of cutter shaft assembly, can not dry land, the paddy field dual-purpose, and what promptly be used for the dry land operation just can not be used for paddy-field-working, otherwise also is.But in China, particularly in the southern province of China, substantially all be water, dry land coexistence, the peasant need be equipped with the cutter shaft assembly of two kinds of rotovators, has increased cost for virtually friend's peasant agricultural machinery input.On the other hand, because the rotary blade of existing rotovator adopts cross symmetry to install, every row's cutter axial spacing on cutter shaft is little, and radial spacing is big, and resistance was big when rotary blade buried, and rotary tillage is deep mixed, is uneven.In addition, the cutter shaft assembly of existing rotovator does not have the weeds protector, and weeds very easily are wound on the rotary blade during work, have both influenced rotary tillage effect and quality, very easily cause mechanical failure again, causes power attenuation to hitching machinery simultaneously yet.
Summary of the invention:
The purpose of this utility model is, provides a kind of with rotary blade shape installation in the shape of a spiral on cutter shaft, and has the weeds protection and press careless device; Adopt cross symmetry to install to solve existing rotary blade, the blade soil-entering resistance is big, and rotary tillage is deep mixed, and weeds easily were wound on the rotary blade when work was, had both influenced rotary tillage effect and quality, easily machinery were caused the compound rotavator knife axle assembly of damage problem again.
The utility model is to realize above-mentioned purpose by following technical solution:
A kind of compound rotavator knife axle assembly, it is by cutter shaft pipe, cultivated tool rest, rotary blade, weeds guard rail, minor axis, spline housing, Lysimachia sikokiana circle and gearbox constitute, it is characterized in that: an end of two cutter shaft pipes is contained in respectively by spline housing on the splined shaft of gearbox both sides, and the other end of two cutter shaft pipes is equipped with minor axis by bearing; On the circumferential surface of every cutter shaft pipe in the shape of a spiral shape be evenly equipped with cultivated tool rest, plough in the tool rest rotary blade be housed; Uniformly on every cutter shaft pipe be equipped with four and be fixed on the support rings of ploughing on the tool rest, uniform on the support ring five weeds guard rails are housed.Described spline housing is provided with the Lysimachia sikokiana circle by a side of gearbox, and minor axis is provided with minor axis Lysimachia sikokiana circle, and the inboard of minor axis Lysimachia sikokiana circle is provided with the anti-careless back-up ring of bearing.
The utility model beneficial effect compared with prior art is:
The rotary blade of this compound rotavator knife axle assembly adopts spiral to install, and the blade soil-entering resistance is little, and soil is not tied plate after the rotary tillage.Effect by the weeds guard rail can prevent weeds winding rotary blade effectively, has improved the rotary tillage effect greatly.This cutter shaft assembly both can adapt to dry land rotary tillage operation, can adapt to the paddy field rotary tillage operation again, had alleviated the input cost of peasant's agricultural machinery.And rotary blade employing activity is installed, and can change cutter according to actual needs easily, to satisfy the job requirements in each farmland, also brings great convenience to service work simultaneously.
Description of drawings:
Fig. 1 is a kind of structural representation of compound rotavator knife axle assembly;
Fig. 2 is a kind of schematic cross-section of cutter shaft assembly of compound rotovator.
Among the figure: 1, cutter shaft pipe, 2, plough tool rest, 3, support ring, 4, rotary blade, 5, the weeds guard rail, 6, the anti-careless back-up ring of bearing, 7, minor axis, 8, spline housing, 9, minor axis Lysimachia sikokiana circle, 10, the Lysimachia sikokiana circle, 11, gearbox.
Embodiment:
This compound rotavator knife axle assembly is made of cutter shaft pipe 1, cultivated tool rest 2, rotary blade 4, weeds guard rail 5, minor axis 7, spline housing 8, Lysimachia sikokiana circle 10 and gearbox 11.One end of two cutter shaft pipes 1 is contained in respectively by spline housing 8 on the splined shaft of gearbox 11 both sides, and spline housing 8 is provided with the Lysimachia sikokiana circle 10 that prevents that weeds from twining by a side of gearbox 11.The other end of two cutter shaft pipes 1 is equipped with minor axis 7 by bearing, and minor axis 7 is provided with minor axis Lysimachia sikokiana circle 9, and the inboard of minor axis Lysimachia sikokiana circle 9 is provided with the anti-careless back-up ring 6 of bearing.On the circumferential surface of every cutter shaft pipe 1 in the shape of a spiral shape be evenly equipped with and plough tool rest 2, plough in the tool rest 2 and be movably installed with rotary blade 4 by bolt; Uniformly on every cutter shaft pipe 1 be equipped with four and be fixed on the support rings of ploughing on the tool rest 23, uniform on the support ring 3 five weeds guard rails 5 are housed, weeds guard rail 5 is made by square steel, weeds guard rail 5 both can be when the rotary tillage operation be pressed the weeds in the farmland and was placed into the soil, prevent that weeds winding rotary blade 4 from influencing the rotary tillage effect, can play the dark effect of limit to rotary blade 4 again, it is dark to prevent that rotary blade 4 from burying, and causes the effect loss (referring to accompanying drawing 1-2) of rotovator.
This compound rotavator knife axle assembly drives the splined shaft rotation of gearbox 11 both sides by the power drive gearbox 11 of rotovator, and then drives cutter shaft pipe 1 and top rotary blade 4 rotations thereof by spline housing 8.Because the rotary blade 4 shape setting in the shape of a spiral on the cutter shaft pipe 1, make rotary blade 4 axially and the spacing radially for the rotary blade that the cross symmetry of existing employing is installed, the quantity that enters the rotary blade 4 of agricultural land soil during work simultaneously will be lacked relatively, and the soil-entering resistance of rotary blade is little.And cutter is little and quantity is many, so the soil of rotary tillage do not tie plate, and balance, hack performance all improve a lot during operation.When the rotary tillage operation, in the weeds in field pressure being placed into the soil by weeds guard rail 5.When at paddy-field-working, weeds guard rail 5 can play balance support and the dark effect of limit, guarantees the degree of depth unanimity that rotary blade 4 enters soil, so this compound rotavator knife axle assembly can adapt to dry land and paddy-field-working.And, can satisfy the job requirements in different farmlands by ploughing the different rotary tillage cutter of replacing on the tool rest 2.
