Abstract
The invention relates to a multifunctional rotary cultivator cutter shaft assembly, and belongs to the technical field of agriculture rotary cultivator fittings. The multifunctional rotary cultivator cutter shaft assembly comprises a cutter shaft tube, plough cutter bases and rotary cutters; a plurality of support rings are mounted at intervals on the cutter shaft tube; the plurality of plough cutter bases are uniformly distributed at intervals on the circumference surface of the cutter shaft tube and between the support rings; the rotary cutters are movably mounted inside the plough cutter bases; a plurality depth limiting rods are uniformly distributed on the circumferences of the support rings; protection covers are respectively arranged on the cutter shaft tube at two end tips of each depth limiting rod. The rotary cutters of the cutter shaft assembly are mounted in a spiral manner, the blade penetration resistance is small, and ploughed soil is not hardened. Due to adoption of the protection covers, an assembling bearing can be effectively prevented from being wound by weeds, and thus the rotary plough effect can be greatly improved. The multifunctional rotary cultivator cutter shaft assembly is applicable to rotary plough operation of dry farmlands and rotary plough operation of paddy fields, and thus the investment cost of agriculture machines can be lowered.
Description
Technical field
The present invention relates to a kind of multifunction rotavator cutter shaft assembly, belong to agricultural rotary tillage machine accessory technical field.
Background technology
Rotary cultivator is a kind of tillage implement that China grows up in the recent period, and rotavator knife axle assembly is one of most important parts of rotary cultivator.The cutter shaft assembly of rotary cultivator is arranged in the frame of rotary cultivator by short axle and bearing block, and rotary blade is arranged on cutter shaft by tool rest, and tool rest uses cross being symmetrically installed on cutter shaft；It integrates cultivated, harrows, and i.e. can reach one time, farmland rotary tillage process 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, and be i.e. used for dry land operation cannot be used for paddy-field-working, otherwise is also.But in China, particularly in the southern province of China, be substantially water, dry land coexists, peasant needs to be equipped with the cutter shaft assembly of two kinds of rotary cultivators, puts into virtually to the agricultural machinery of friend peasant and adds cost.On the other hand, owing to the rotary blade of existing rotary cultivator uses cross being symmetrically installed, 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, is uneven.It addition, the cutter shaft assembly of existing rotary cultivator does not has weeds preventer, during work, weeds are easily wound on rotary blade, have both affected rotary tillage effect and quality, the most easily cause mechanical failure, also cause power attenuation to hitching machinery simultaneously.
Summary of the invention
It is an object of the invention to, there is provided a kind of simple in construction, practicality good, can effectively solve existing rotary blade and use cross being symmetrically installed, blade soil-entering resistance is big, rotary tillage is deep mixed, when work is, weeds are easily wound on rotary blade, both affected rotary tillage effect and quality, machinery easily causes again the multifunction rotavator cutter shaft assembly of damage problem.
The technical scheme is that
A kind of multifunction rotavator cutter shaft assembly, including cutter shaft pipe, ploughs tool rest and rotary blade；It is characterized in that: be spaced shape on cutter shaft pipe and multiple support ring is installed, the cutter shaft pipe circumferential surface between support ring is evenly equipped with multiple cultivated tool rest in interval dislocation (spiral) shape, movable equipped with rotary blade in each cultivated tool rest；It is evenly equipped with multiple depth limiting pole on the circumference of support ring, is connected with each other by depth limiting pole between each support ring；It is respectively arranged with protective cover on cutter shaft pipe on termination, depth limiting pole two ends.
Described protective cover is fixing with depth limiting pole to be connected.
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 cross section of described depth limiting pole is U-shaped.
The present invention having the beneficial effects that compared with prior art:
The rotary blade of this multifunction rotavator cutter shaft assembly uses spiral to install, and blade soil-entering resistance is little, soil not knot tying after rotary tillage.Weeds can be effectively prevented by protective cover and be wound around assembling bearing, substantially increase rotary tillage effect.This cutter shaft assembly had both been suitable for dry land rotary tillage process, adapted to again paddy field rotary tillage operation, alleviated the input cost of peasant's agricultural machinery.And rotary blade employing activity installation, cutter can be changed the most easily, to meet the job requirements in each farmland, also bring great convenience to service work simultaneously.

Detailed description of the invention
This multifunction rotavator cutter shaft assembly includes cutter shaft pipe 1, ploughs tool rest 2 and rotary blade 4.Being spaced shape on cutter shaft pipe 1 and be provided with multiple support ring 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.
It is evenly equipped with multiple cultivated tool rest 2 in interval dislocation or helical form on cutter shaft pipe 1 circumferential surface between support ring 3, movable equipped with rotary blade 4 in each cultivated tool rest 2.It is evenly equipped with multiple depth limiting pole 5 on the circumference of support ring 3, is connected with each other by depth limiting pole 5 between each support ring 3.Depth limiting pole 5 is circle strip or rectangular slat shape；Also the bar steel that hollow square steel or cross section are U-shaped can be used to be made.
It is respectively arranged with protective cover 6 on cutter shaft pipe 1 on termination, depth limiting pole 5 two ends.Protective cover 6 is in the form of annular discs, and its edge is provided with protection edge, and the centre of protective cover 6 is provided with pilot hole.Protective cover 6 is fixing with depth limiting pole 5 to be connected.The effect of protective cover 6 is operationally to strengthen assembling bearing and the protection of oil sealing, it is to avoid the winding of weeds.
The rotary blade 4 of this cutter shaft assembly uses spiral or helical form to install, and can effectively reduce the soil-entering resistance of blade, and make the not knot tying of the soil after rotary tillage during work；Thus substantially increase rotary tillage effect.This cutter shaft assembly had both been suitable for dry land rotary tillage process, adapted to again paddy field rotary tillage operation, alleviated the input cost of peasant's agricultural machinery.And rotary blade employing activity installation, cutter can be changed the most easily, to meet the job requirements in each farmland, also bring great convenience to service work simultaneously.
