Specific embodiment
The dual-purpose rotavator knife axle assembly of the floods and droughts includes cutter shaft 1, coulter seat 2, rotary blade 3, support plate 4 and water caltrop depth limiting pole
5.Water caltrop depth limiting pole 5 not only limits the embedded depth of rotary blade 3, while rotary blade 3 being cooperated to increase hack effect, and being used for will
The weeds pressure of soil surface is embedded in soil, to accelerate it to rot.
One end of cutter shaft 1 is equipped with spline housing 8, spline housing 8 for being connect with the gearbox of rotary cultivator 10, cutter shaft 1 it is another
End is equipped with bearing block 9, bearing block 9 for connect with the rack of rotary cultivator 10, close to the rack of bearing block 9 on be fixed with receipts side knife
6.It receives side knife 6 to be made of colter body 12 and attachment base 13, attachment base 13 is in curved arc shape, and 13 updip inclined weld of attachment base is equipped with colter body
12, it receives side knife 6 and is mounted on the rack by bolt by the fixation hole on attachment base 13.The purpose for receiving side knife 6 is to 3 nothing of rotary blade
The farmland edge of method operation carries out turning over operation, and to avoid farmland, there are homework corners, and the agriculture to assembly limit simultaneously
Field soil plays one and inwardly puts together, keeps the smooth of operation band limit.
It is evenly equipped on 9 circumference of spline housing 8 and bearing block and cuts blade 7.The effect for cutting blade 7 is to chop off to be wrapped on cutter shaft 1
Weeds, to prevent weeds from entering the effect of bearing block twines dead cutter shaft 1 or causes rotary cultivator 10 loss.
Interval, which is welded, on cutter shaft 1 between spline housing 8 and bearing block 9 3-5 support plates 4, and support plate 4 is whole
Annular shape that is circular or being made of two semicircles.
Support plate 4 is connected with each other by 5 water caltrop depth limiting poles 5 uniformly distributed on 4 circumference of support plate between each other；Support plate 4
Connection is welded between water caltrop depth limiting pole 5.Amplification is fixed with by amplification tool apron 14 on the bearing block 9 of 5 end point of water caltrop depth limiting pole
Knife 11, amplification knife 11 are curved arc shape, and the bottom end of amplification knife 11 is provided with the attachment base being bent to form, is provided with fixation on attachment base
Hole (19)；Amplification knife 11 is fixedly mounted on amplification tool apron 14 by fixing bolt by fixation hole 19.
Amplification tool apron 14 is made of the fixed plate 15 of curved arc shape and fixing seat 16, and being welded in fixed plate 15 has fixing seat 16,
Fixing seat 16 is in cuboid, is provided with fitting groove 17 in fixing seat 16, pilot hole 18 is provided in fitting groove 17；Amplification knife 11 by
Fixing bolt is packed on amplification tool apron 14 by the cooperation of pilot hole 18 and fixation hole 19.The effect of amplification knife 11 is to cutter shaft
1 carries out rotary tillage with the farmland of rack junction, solve the problems, such as existing rotary blade 3 to the farmland of junction can not operation, by
This increases working width.
When amplification tool apron 14 assembles, it is welded by fixed plate 15 in the outside of bearing block 9, while by amplification knife 11 by water caltrop
It stretches out between depth limiting pole 5, for the assembly intensity for increasing amplification tool apron 14, fixing seat 16 and water caltrop depth limiting pole 5 can also be welded.Work
During work, once amplification knife 11 is worn, easily it can be replaced by fixing bolt, without together with amplification
14 integral replacing of tool apron.
Coulter seat 2 is evenly equipped on cutter shaft circumference between support plate, coulter seat 2 is on the cutter shaft 1 between water caltrop depth limiting pole 5
Setting (radially misplacing) wave-shaped, the mutual coulter seat 2 of each water caltrop depth limiting pole 5 are axial in dislocation shape setting, coulter
Seat 2 is arranged in the shape of a spiral on the whole circumference of cutter shaft 1.Rotary blade 3 is fixed with by bolt on coulter seat 2；Rotary blade 3 is in phase
It is in be oppositely arranged on adjacent coulter seat 2.It also can be in set on cutter shaft 1 in the same direction by rotary blade 3 according to the actual conditions of field operation
It sets, but the rotary blade 3 between two cutter shafts 1 must keep being oppositely arranged.
Since coulter seat 2 is arranged in the shape of a spiral on the whole circumference of cutter shaft 1, and rotary blade 3 is on adjacent coulter seat 2
It is oppositely arranged；So that the rotary blade 3 on coulter seat 2 is more smoother in the circumference of cutter shaft 1, and then enter 3 sequence of rotary blade
Soil；While reducing the soil-entering resistance of rotary blade 3, make after rotary tillage soil not knot tying；Effectively increase the broken of agricultural land soil
Effect.Solving existing rotary cultivator is that 3 array of rotary blade is distributed on the circumferencial direction of tool roller axis, and when work buries simultaneously
Rotary blade quantity it is more, cause rotary blade to bury difficulty, it is big to lead to be driven power consumption, the stationary performance and broken soil performance of operation
The problem of difference, crop root residue coverage condition is affected.
The cutter shaft assembly is installed in symmetry shape the two sides of gearbox in assembly, in the course of work, due to coulter seat 2
It is arranged in the shape of a spiral on the whole circumference of cutter shaft 1 on cutter shaft 1 in the installation of dislocation shape and coulter seat 2, and rotary blade 3 exists
It is installed in opposite directions on adjacent coulter seat 2；So that 3 soil-entering resistance of rotary blade is small, soil not knot tying after rotary tillage；Greatly improve rotary tillage
Effect.Solve difficulty of burying caused by the distribution of existing rotary blade array, transmission power consumption is big, when operation steady hack
Can and it bury the impacted problem of careless performance.Receipts side knife 6 by the amplification knife 11 on water caltrop depth limiting pole 5 and in rack, can have
Effect increases working width.The cutter shaft assembly has structure simple, the good feature of practicability, pacifies especially suitable for floods and droughts rotary tillage machine
Dress uses.
