Make efficiency high, the native ball shape rule cut out, easy packed and transported.And the present invention uses creeper undercarriage, structure is suitable for
Property strong, the base, nursery of the bad working environments such as hills landforms, intensive plantation and muddy road can be met.
The hydraulic plunger variable pump 22 of the present invention, under the drive of electromotor 1, draws low-pressure hydraulic oil from hydraulic oil container 21
Being converted into high pressure liquid force feed, high-pressure output port P2, P3 of hydraulic plunger variable pump 22 are in high-pressure oil pipe 23 is connected to control station 6
The oil-in of multiple directional control valve 24, the low-voltage output outlet P1 of hydraulic plunger variable pump 22 is connected to guide through fluid pressure line simultaneously
The oil inlet P of control valve 3, it is each that delivery outlet a, b, c, d of pilot-actuated valve 3 is connected to multiple directional control valve 24 through fluid pressure line
Pilot control opening, each delivery outlet of multi-way control valve 24 be connected respectively to hoist cylinder 8, cutting motor 12, vibrating motor 25
With running motor 19.The present invention is arranged on the angle of the handle 3-1 of the pilot-actuated valve 3 of seat 2 left and right sides by manipulation, to change
Become the output pressure of pilot-actuated valve 3 delivery outlet a, b, c, d, thus change the spool stroke of multiple directional control valve 24 and opening degree
Size, the final size controlling multiple directional control valve 24 output flow, reach to be precisely controlled movement velocity and the walking of hoist cylinder 8
Motor 19, cutting motor 12, the output speed of vibrating motor 25.
The voltage-regulation principle of pilot-actuated valve 3 of the present invention: pilot-actuated valve 3 is under not mode of operation, and handle 3-1 is at reset bullet
Jack-up plunger 3-3 under the effect of spring 3-5, with the arc platen 3-10 above jack-up plunger 3-3, makes spool 3-6 and handle simultaneously
3-1 is maintained at middle position, and now delivery outlet a, b, c, d of pilot-actuated valve 3 is by the hole 3-7 in shell 3-8 body and oil return inlet T phase
Logical, pressure oil returns to hydraulic oil container 21 by low pressure line.
When pulling handle 3-1, the vertical centre relative to universal joint 3-9 of the arc platen 3-10 on handle 3-1 swings.
During swinging, arc platen 3-10 will press under plunger 3-3, and plunger 3-3 is depressed with compression reseting spring 3-5 and control
Spring 3-4, now starts to promote spool 3-6 to move down under the effect controlling spring 3-4, to close closed shell by spool 3-6
Hole 3-7 in body 3-8, thus correspondingly close delivery outlet a, b, c, d of pilot-actuated valve 3 and connecting of oil return inlet T, same with this
Time, delivery outlet a, b, c, d of corresponding pilot-actuated valve is communicated with oil inlet P by the hole 3-7 in housing 3-8, and pressure oil arrives
Reach delivery outlet a, b, c, d of correspondingly pilot-actuated valve 3.
Give to locate between the power of spool 3-6 and the hydraulic coupling of pilot-actuated valve 3 delivery outlet a, b, c, d when controlling spring 3-4
When balance, the control stage starts.Under spool 3-6 and the interaction that controls between spring 3-4, pilot-actuated valve 3 defeated
The pressure of outlet a, b, c, d is proportional to the stroke of plunger 3-3, thus relation proportional to the position of handle 3-1.Therefore this
The built-in air relief valve of bright pilot-actuated valve 3 is proportion type reducing valve, can finely control the motion of each executive component, thus accurately
Ground reaches work requirements.
Preferably, described arc platen 3-10 appoints in the range of 25 ° the present invention around the vertical center line of described universal joint 3-9
Meaning swings.It is sitting on seat 2 by operator, the handle 3-1 of manual operation pilot-actuated valve 3, to change the angle of handle 3-1
Degree, thus change the angle of the arc platen 3-10 vertical center line relative to universal joint 3-9, to change plunger 3-3 by arc
The stroke that platen 3-10 presses down, thus change control spring 3-4 and give the power of spool 3-6, with at spool 3-6 and control spring 3-
Under interaction between 4, it is achieved the pressure of delivery outlet a, b, c, d of pilot-actuated valve 3 pass proportional to the stroke of plunger 3-3
System, to finely control the motion of each executive component, thus accurately achieves work requirements.
The present invention is when running motor 19 rotates, and the tooth of driving wheel 18 can pull the axle of the crawler belt wheel track of track rail assembly 14
Set, thus drive track rail assembly 14 to rotate, to realize the rotating function of complete machine.Thrust wheel 16 supports and comes from walker 17
The weight of complete machine, by the weight transfer creeper tread to track rail assembly 14, and allows crawler belt advance along wheel direction or to retreat, torr
The chain being positioned at the track rail assembly 14 on the upside of walker 17 lifted by sprocket wheel 7, prevents chain hook or the abrasion row of track rail assembly 14
Walk frame 17.
The present invention regulates, by hoist cylinder 8, the angle that cutting tip 9 buries.When multiple directional control valve 24 distribution comes
When hydraulic energy is transported to cut motor 12 by hydraulic hose, cutting motor 12 rotarily drives cutting tip 9 and cuts soil, completes
The cutting of trees ' root soil ball.Vibrating motor 25 achieves percussion when cutting tip 9 cuts trees ' root soil ball simultaneously,
To realize the trees ' root intact cutting of soil ball, improve cutting efficiency.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The technology of the industry
Personnel, it should be appreciated that the present invention is not restricted to the described embodiments, simply illustrating this described in above-described embodiment and description
The principle of invention, the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these become
Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and
Equivalent defines.
