Abstract
The utility model relates to a tree mover cutter in forestry machine field especially relates to an elasticity spiral sword device, including elasticity spiral sword and support cambered axle, elasticity spiral broach shell dress on supporting the cambered axle to the heliciform distributes on supporting the cambered axle. This elasticity spiral sword device simple structure, it is moderate to cut into power, can in time see the native book that cuts off ground through the helical angle, reduces tool resistance, increases cutter life, and the spherical form of soil that digs is regular, and is little to the injury of trees root system, has improved the survival rate that trees were transplanted.
Description
Technical field
This utility model is related to the tree mover cutter in agriculture and forestry machinery field, more particularly to a kind of elastic helix knife system.
Background technology
At present, there is technological deficiency, the soil ball that petal type tree mover cutter digs out in domestic tree-digging machine with soil balls cutter for same
Irregularly, and strength is larger, serious to tree root destruction, Hand saw is difficult the trunk position for cutting tree root, in addition it is also necessary to large-scale
Hang equipment auxiliary to complete, in addition the cutter general structure of tree mover is all very complicated, and specification is single, it is impossible to change soil ball size, should
There is certain limitation used time.
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned, and provides a kind of simple structure, and cutting-in force is moderate, specification
It is various, a kind of easy to operate, robust elastic helix knife system.
The technical scheme that this utility model is adopted is：A kind of elastic helix knife system, including elastic helix knife and support
Cambered axle, described elastic helix broach shell is mounted on support cambered axle, and the spiral distribution on cambered axle is supported.
Preferably, one end of the elastic helix knife is fixedly connected on cambered axle is supported, and the other end is curved to be sleeved on support
Free end on axle.
Preferably, the elastic helix knife is spring shape, and is provided with helical angle.
Preferably, the edge of the elastic helix knife is provided with blade, and described blade is monolateral sword, and sword oblique angle is
2º-50º。
Preferably, the centrage for supporting cambered axle is in semicircular arc.
The utility model has the advantage of：Elastic helix knife system disclosed in this utility model, simple structure, cutting-in force is fitted
In, ground can be sent the native book of cutting by helical angle in time, reduce tool resistance, increase cutter life, the soil of digging
Ball regular shape, injures little to tree root, improves the survival rate of tree grafting growth.
Description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is the sectional view of this utility model elastic helix knife.
In figure：1- elastic helix knives, 2- supports cambered axle, 3- blades.
Specific embodiment
A kind of elastic helix knife system, as shown in figure 1, including elastic helix knife 1 and cambered axle 2 is supported, in supporting cambered axle 2
Heart line is in semicircular arc, and elastic helix knife 1 is sleeved on support cambered axle 2, and the spiral distribution on cambered axle 2 is supported.Elastic spiral shell
One end of rotary knife 1 is fixedly connected on cambered axle 2 is supported, and the other end is to be sleeved on the free end supported on cambered axle 2, elastic helix knife
1 is spring shape, and is provided with helical angle, and can be bent deformation, as shown in Fig. 2 the edge of elastic helix knife 1
Blade 10 is provided with, blade 10 is monolateral sword, and sword oblique angle is 2-50.The blade 10 of elastic helix knife 1 makes through heat treatment
Used time, elastic helix knife 1 is around the center curvature deformation rotation of support cambered axle 2, while support cambered axle 2 to rotate around the line of two-end-point,
The blade 10 of elastic helix knife 1 completes the action for cutting soil and tree root, and the wherein effect of helical angle is delivered in unnecessary soil
Above the ground, support cambered axle 2 to complete feed motion, support cambered axle 2 rotate to trees opposite side above the ground when just complete
Elastic helix knife 1 digs the action of tree, and the band soil of tree root is shaped as dome-type, injures little to tree root, improves trees
The survival rate of transplanting.
