Description
Technical field
The utility model relates to a kind of rooter, belongs to farmland or garden rotary cultivator is digged hay knife design field.
Background technique
In family arable land or garden plantation, small-sized rotary cultivator is widely used, and needs to pacify in the shaft of rotary cultivator
Dress multiple groups are digged.The cutter tooth and mounting hole for traditionally digging circumferential are disposed as three, and blade tooth group number is identical with positioning hole count,
Arbitrarily cutter tooth and location hole can be positioned one by one in blade installation, i.e., blade can arbitrarily be installed between 120 °；But three
Tooth, which is digged, is more suitable for big field farming use, but refines for tillage requirements for the small range in family garden vegetable plot, digs
Hack ability is weaker, and multitool tooth rotary cultivator is more suitable for family's use.It common are four teeth, six serrated knife chip architectures, but for
For the digging of the multiple tooth blades such as four teeth, six teeth, octadentate, since number of teeth is different from installation hole count, adjacent knife blades when installation
Cutter tooth need offset angular to install to guarantee to dig effect；But in blade installation, user or installer are in assembly
It is easy to appear and empty tooth is installed or occurred to tooth, be difficult assurance setting angle causes to install with the uniform crossover etc. for guaranteeing cutter tooth angle
Problem occurs frequently and repeatedly does over again.
Mainly a kind of multiple groups flat cutter being mounted in shaft that rotary cultivator used dig, this flat cutter can be to hard soil
Ground is deep ploughed, but is difficult to soil-breaking spade except grass roots in field medium-height grass and more root；Currently used dig also has in shaft
Shovel grass tulwar of the upper installation tulwar to root out weeds, but the ability of breaking ground of tulwar is weaker, grass roots is also easy to be wrapped in tulwar
On, farming personnel need often cleaning tulwar.In addition, this dig is essentially all unitary design at present, when some cutters tooth
Through a long time is worn after, the using effect for the piece that influences entirely to dig, if directly abandoning and causing the waste of resource.
