Description
Technical field
This utility model is related to a kind of multifunction rotavator cutter shaft assembly, the agriculture rotary tillage machine accessory technical field of category.
Background technology
Rotary cultivator is a kind of tillage implement that China grows up in the recent period, and rotavator knife axle assembly is that rotary cultivator is most important
One of part.The cutter shaft assembly of rotary cultivator passes through short axle and bearing block is arranged in the frame of rotary cultivator, and rotary blade passes through tool rest
On cutter shaft, tool rest is symmetrically installed using cross on cutter shaft；It integrates cultivated, harrows, and the rotary tillage in farmland is made
Industry is can reach with farm cattle plough, rake working effect several times.Current rotary cultivator is limited because of the version of cutter shaft assembly, it is impossible to
Dry land, paddy field dual-purpose, i.e., for the paddy-field-working that cannot be used for of dry land operation, otherwise be also.But in China, particularly at me
The southern province of state, is substantially water, dry land and coexists, and peasant needs the cutter shaft assembly for being equipped with two kinds of rotary cultivators, virtually to agriculture
The agricultural machinery input of the friend people increased cost.On the other hand, as the rotary blade of existing rotary cultivator is using cross symmetrical
Install, often row's cutter axial spacing on cutter shaft is little, and radial spacing is big, and when rotary blade buries, resistance is big, and rotary tillage is deep mixed, high
Low injustice.In addition, the cutter shaft assembly of existing rotary cultivator does not have weeds preventer, during work, weeds are easily wound into rotary blade
On, rotary tillage effect and quality had both been affected, and had easily caused mechanical failure, while also power attenuation is caused to hitching machinery.
The content of the invention
The purpose of this utility model is, there is provided a kind of simple structure, practicality are good, can the existing rotary blade of effectively solving adopt
It is symmetrically installed with cross, blade soil-entering resistance is big, and rotary tillage is deep mixed, and when work is, weeds are easily wound on rotary blade, both
Rotary tillage effect and quality are affected, and the multifunction rotavator cutter shaft assembly of damage problem is easily caused to machinery.
The technical solution of the utility model is：
A kind of multifunction rotavator cutter shaft assembly, including cutter shaft pipe, cultivated tool rest and rotary blade；It is characterized in that：Cutter shaft pipe
Upper interval shape is provided with multiple support rings, in interval dislocation on the cutter shaft pipe circumferential surface between support ring（Spiral）Shape is evenly equipped with
Multiple cultivated tool rests, activity in each cultivated tool rest are equipped with rotary blade；Be evenly equipped with multiple depth limiting poles on the circumference of support ring, each support ring it
Between be connected with each other by depth limiting pole；Protective cover is respectively arranged with cutter shaft pipe on the termination of depth limiting pole two ends.
Described protective cover is fixedly connected with depth limiting pole.
Described protective cover is in the form of annular discs, and its edge is provided with protection edge, and the centre of protective cover is provided with pilot hole.
Described support ring is polygon ring, and the quantity of support ring is 3 or 4 or 5.
Described support ring is the circular discs being made up of two semicircles.
Described depth limiting pole is circle strip or rectangular slat shape；Described depth limiting pole is made up of hollow square steel.
Its section of described depth limiting pole is U-shaped.
This utility model beneficial effect compared with prior art is：
The rotary blade of the multifunction rotavator cutter shaft assembly is installed using spiral, and blade soil-entering resistance is little, soil after rotary tillage
Not knot tying.Weeds winding assembling bearing can be effectively prevented by protective cover, rotary tillage effect is substantially increased.The cutter shaft assembly was both
Dry land rotary tillage process is suitable for, paddy field rotary tillage operation is adapted to again, the input cost of peasant's agricultural machinery is alleviated.And rotary blade
Using activity installation, cutter can be easily changed according to actual needs, to meet the job requirements in each farmland, while also to maintenance
Work brings great convenience.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A-A in Fig. 1 to structural representation.
In figure：1st, cutter shaft pipe, 2, plough tool rest, 3, support ring, 4, rotary blade, 5, depth limiting pole, 6, protective cover.
Specific embodiment
The multifunction rotavator cutter shaft assembly includes cutter shaft pipe 1, ploughs tool rest 2 and rotary blade 4.Shape peace is spaced on cutter shaft pipe 1
Equipped with multiple support rings 3, the quantity of support ring 3 is 3 or 4 or 5.Support ring 3 is the circular rings being made up of two semicircles.
Also support ring 3 can be set to polygon ring.
Multiple cultivated tool rests 2 are evenly equipped with interval dislocation or helical form on 1 circumferential surface of cutter shaft pipe between support ring 3, respectively
Activity in cultivated tool rest 2 is equipped with rotary blade 4.Multiple depth limiting poles 5 are evenly equipped with the circumference of support ring 3, by limit between each support ring 3
Deep bar 5 is connected with each other.Depth limiting pole 5 is circle strip or rectangular slat shape；Hollow square steel or section can also be adopted for U-shaped bar steel
Form.
Protective cover 6 is respectively arranged with cutter shaft pipe 1 on 5 two ends termination of depth limiting pole.Protective cover 6 is in the form of annular discs, its edge
Protection edge is provided with, the centre of protective cover 6 is provided with pilot hole.Protective cover 6 is fixedly connected with depth limiting pole 5.Protective cover 6
Effect is operationally to strengthen the protection to assembling bearing and oil sealing, it is to avoid the winding of weeds.
The rotary blade 4 of the cutter shaft assembly adopts spiral or helical form to install, and the resistance of burying of blade can be effectively reduced during work
Power, and make the not knot tying of the soil after rotary tillage；So as to substantially increase rotary tillage effect.The cutter shaft assembly had both been suitable for dry land rotary tillage
Operation, adapts to paddy field rotary tillage operation again, alleviates the input cost of peasant's agricultural machinery.And rotary blade is using activity installation,
Cutter can be easily changed according to actual needs, to meet the job requirements in each farmland, while also bringing pole to service work
Big facility.
