Fig. 5 is the first visual angle schematic diagram of whirlpool plough 200 in the utility model embodiment；Fig. 6 is the utility model implementation
Second visual angle schematic diagram of whirlpool plough 200 in example.Referring to figure 5. with Fig. 6 and in conjunction with aforementioned figures, in the present embodiment, whirlpool
Plough 200 include knife rest 210, tool arm 220, plate-like cutterhead 230 and be connected to the second elastic component of knife rest 210 and tool arm 220
224.Cutterhead 230 is rotationally connected with tool arm 220, and tool arm 220 is connected to hitch structure 300 by knife rest 210, whirlpool plough 200 with
The position of buffer-type subsoiling plow 100 corresponds, and each whirlpool plough 200 is respectively positioned on corresponding buffer-type subsoiling plow 100 in default side
Upward front.So that whirlpool plough 200 first cuts soil, and buffer-type subsoiling plow 100 carries out further again when working operation
It loosens the soil.In the present embodiment, the outer edge cutting edge of cutterhead 230 is waveform, also has gyrate ripple struction in disk.
Further, tool arm 220 is rotationally connected with knife rest 210 by the circular shaft of a transverse direction, and the second elastic component 224 is used for
Apply restoring force to tool arm 220 when tool arm 220 is rotated with movable knife disc 230 to the rear of preset direction.With buffer-type subsoiling plow
100 basic principle is identical, and the second elastic component 224 of setting can be driven backward to allow cutterhead 230 when encountering obstacle
Tool arm 220 rotates, to bypass obstacle, then makes its reset by the second elastic component 224.
In the present embodiment, knife rest 210 includes two interval settings on the length direction of front-axle beam 310 or the back rest 320
Bracket 211, tool arm 220 are rotationally connected between one end of two brackets 211, and the other end of two brackets 211 removably connects
It is connected to hitch structure 300, two brackets 211 have substantially formed v-shaped structure.One end tool that bracket 211 is connect with hitch structure 300
There is the groove body that section is rectangular, the plate body that this end of bracket 211 is L-shaped with another is bolted connection and clamps jointly
The firmly front-axle beam 310 or the back rest 320 of hitch structure 300.
Further, fixed plate 212 is provided on knife rest 210, fixed plate 212 is fixedly connected under two brackets 211
End, and it is located at the front side of entire knife rest 210.Shaft 222 is provided on tool arm 220, a part of shaft 222 is worn from below to up
Cross fixed plate 212；Second elastic component 224 is sheathed on the upper part that shaft 222 passes through fixed plate 212, and shaft 222, which passes through, to be fixed
One end (i.e. upper end) of plate 212 is provided with limit plate 223；One end of second elastic component 224 is connected to fixed plate 212,
The other end of second elastic component 224 is connected to limit plate 223.In the present embodiment, the second elastic component 224 is bullet
Spring.
Specifically, the tool arm 220 in the present embodiment is two strip components of parallel interval setting.And cutterhead 230 rotates
Be connected between the two strip components and be located at tool arm 220 lower end (i.e. operation when close to soil one end), and tool arm 220
Upper end be rotationally connected with the position of knife rest 210 and be provided with a rotor plate 221, and shaft 222 is then fixedly installed on the rotation
The upper surface of plate 221, and fixed plate 212 is extended upward through from the downside of fixed plate 212.
Therefore, the second elastic component 224 is similar with the action principle of the first elastic component 132, when tool arm 220 rotates backward,
Shaft 222 moves down, and the second elastic component 224 is compressed, therefore the second elastic component 224 persistently provides a restoring force, to make
Whirlpool plough 200 is obtained after around obstacle, tool arm 220 can be restored to normal operating position, to continue the work that loosens the soil
Industry.
The working principle for cutting root loosening device 10 of the present embodiment is:
In the operation process that loosens the soil, the cutterhead 230 of whirlpool plough 200 can take the lead in cutting upper soll layer (such as 0~20cm
Depth), 5 rills are cut out, and cut off the sturdy root system of upper soil layer.Lower soil layer is destroyed followed by buffer-type subsoiling plow 100
(such as depth of 20~40cm) it is horizontal walk radicula net, and operation of further being loosened the soil.Cutterhead 230 is roller, is buried
It is relatively easy to, since soil is cut open in advance, for subsequent subsoiling plow when loosening the soil, resistance also can be smaller.In addition, encountering
Hard whirlpool plough 200 and buffer-type subsoiling plow 100 can do a degree of rotation when being difficult to mobile obstacle, bypass
Normal operating position is restored to by elastic component again after obstacle, which greatly enhances the efficiency for operation of loosening the soil, but also cutter head
124, cutterhead 230 can be buffered when encountering obstacle, reduced a possibility that equipment is impaired, improved the service life of equipment.
In conclusion a kind of buffer-type subsoiling plow of the utility model embodiment includes fixation kit, is rotationally connected with admittedly
Determine the colter component of component and is connected to the buffer unit of fixation kit and colter component.Fixation kit is for being connected to outside
Hitch structure.Colter component includes relative to the rotatable colter of fixation kit.Buffer unit include the first elastic component, first
One end of elastic component is rotationally connected with fixation kit, and the other end of the first elastic component is connected to colter component；First elastic component is used
In when colter component relative to fixation kit rotate when to colter component provide restoring force.Make colter in operation of loosening the soil in this way
When, appropriate rotation can be done after meeting with obstruction, to bypass obstacle, and can be extensive under the return action of buffer unit
Operating position is arrived again continues operation of loosening the soil.It can be improved the efficiency for operation of entirely loosening the soil in this way, and equipment can be improved
Because being easy impaired problem after striking obstruction.
The root loosening device of cutting of the utility model embodiment includes above-mentioned buffer-type subsoiling plow, therefore is also had above-mentioned
Beneficial effect.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
