23, wherein, main shovel arm 21 is fixedly linked with frame 1, and one end of base plate 22 is connected with main shovel arm 21, and pair shovel arm 23 is connected in base plate
22 other end, and it is parallel with main shovel arm 21, and main shovel arm 21, base plate 22 and secondary shovel arm 23 constitute U-shaped plantlet uprising shovel, the U
The front end of type shovel offers blade, and as shown in fig. 1, by bolt-connection in frame 1, main shovel arm 21 is from base plate for main shovel arm 21
Edge a knife in 0.6m for ensureing that nursery stock side root system is cut off, the main shovel installation site of arm 21 and perpendicular vertical plane into 2 ° -5 ° of angle,
This angle can ensure smoothly to be buried during 2 operation of plantlet uprising shovel；Pair shovel arm 23 is to constitute the U-shaped another arm for digging seedling device, and shovel side arm is high
Spend for 0.3m～0.5m, and dig seedling deep equality, all edge a knife in short transverse, the root system for ensureing nursery stock opposite side is complete
Portion is cut off；To constitute the U-shaped base for digging seedling device, the front end of base plate 22 edges a knife base plate 22, for ensureing the root of nursery stock bottom
System is all cut off, and the width of base plate 22 is 0.5m～0.6m, and U-shape structure can ensure that the both sides and bottom three for excavating seedling root
Individual azimuth dimension so that the main root of root system, lateral root and fibrous root retain perfect, and then ensure that survival rate is higher after transplanted seedling tree.
Further, the lifting plate 25 being welded on the base plate 22, lifting plate 25 and bottom are also included in the present embodiment
One end of the welding of plate 22 is less than the other end of its own, and lifting plate 25 and the welding position of base plate 22 and the position of putting the first edge on a knife or a pair of scissors of base plate 22
Distance is put for 50mm-70mm, ball-plant wood root system is moved rearwards by along lifting plate 25.
Loose in order to carry out to the soil of seedling root, the orchard lifting device disclosed in the present embodiment also includes
The loose mechanism 11 of root soil, and for providing the transmission system of power for the loose mechanism 11 of root soil, wherein, root soil
Loose mechanism 11 includes：Vibratory sieve and linking arm 111, transmission system includes power input shaft 10, gearbox 5, rotating disk 12, bias
Handle 13 and connecting rod, vibratory sieve is hinged on the base plate 22 of plantlet uprising shovel 2 by shank 14, and the shank 14 is vertically arranged,
As shown in Figure 3, linking arm 111 is connected with one end of vibratory sieve, and power input shaft 10 is used for the output shaft phase with dynamic power machine
Even, power is exported after gearbox 5 by the output shaft of gearbox 5, Bevel Gear Transmission is should be in gearbox 5, to realize moving
The break-in of power.Rotating disk 12 is rotatably attached in frame 1, cam lever 13 it is eccentric it is fixed on a turntable 12, rotating disk 12 and speed change
The output shaft of case 5 is connected by driving-chain or belt 3, and one end and the cam lever 13 of connecting rod are hinged, the other end and linking arm 111
It is hinged.
It is understood that rotating disk 12, cam lever 13 and connecting rod constitute toggle, in the band of cam lever 13
Under dynamic, connecting rod will vibrate before and after carrying out, and under the drive of connecting rod, one end that linking arm 111 is connected with connecting rod also will move forward and backward,
Because vibratory sieve is hinged on the base plate 22 of plantlet uprising shovel 2 by shank 14, therefore turn before and after vibratory sieve will be carried out along shank 14
Dynamic, this just can be realized to the loose of ball-plant wood root soil, and the soil of nursery stock root is vibrated, and realize seedling root
Separate with soil, be that artificial drawing nursery stock and pickup nursery stock provide facility.
In order to avoid during lifting there is crooked, the orchard lifting device disclosed in the present embodiment, also in main shovel in nursery stock
Shovel arm wing branch 24 is welded on arm 21 and secondary shovel arm 23, these wing branches can be oriented to nursery stock, nursery stock is moved from front to back
It is dynamic, it is to avoid to incline；Based on the reason for same, being also provided with the rear portion of vibratory sieve in the present embodiment prevents nursery stock or so crooked
Vibratory sieve wing branch 112, as shown in Figures 1 and 2.
It will be appreciated by persons skilled in the art that after plantlet uprising shovel 2 penetrates into soil, the resistance of the side of frame 1 will be notable
Increase, this can cause frame 1 that deflection is produced in the presence of moment of torsion, in order to ensure that frame 1 can be along going straight ahead, the present embodiment
In be also provided with balanced controls in frame 1, the balanced controls and plantlet uprising shovel 2 are separately positioned on the both sides of frame 1.
Balanced controls can be the break shovel or rotary tillage loosening device for chesson, and break shovel includes the He of shovel wing 92
Break shovel arm 91, break shovel arm 91 is fixedly connected in frame 1, and the fabric width of shovel wing 92 is preferably equal with the fabric width of plantlet uprising shovel 2,
To make the resistance suffered by it reach unanimity with plantlet uprising shovel 2 as far as possible, also ensure that nursery stock is mined rear nursery soil in addition whole
Plot is conducive to the growth of crop of lower season by loose one time.It can be seen that, on the one hand balanced controls can avoid frame 1 from offseting, another
Aspect crimped to the tire of dynamic power machine can also carry out loose.
When balanced controls are rotary tillage loosening device, power drive rotary cultivator attachment can be drawn from the opposite side of gearbox 5
Operated, the working width of rotary tillage loosening device and depth of implements parameter are carried out according to the operation resistance that plantlet uprising shovel 2 is produced
Match somebody with somebody, to reach the double action of dynamic balance and chesson.
In order to further optimize the technical scheme in above-described embodiment, so that the terrain clearance of frame 1 is adjustable, in this enforcement
In example, hollow land wheel is provided with frame 1 standpipe 7 is installed, installed and multigroup installing hole is provided with standpipe, land wheel is pacified with land wheel
Dress arm 6 is connected, and land wheel installing arm 6 is inserted in land wheel installation standpipe 7, and bolt connection installs the one of which of standpipe 7 peace in land wheel
In dress hole, by changing different installing holes, it is possible to achieve the regulation of the terrain clearance of frame 1.
In addition, a kind of adjustable technical scheme of the terrain clearance of frame 1 is also disclosed in the present embodiment, in the present embodiment
In, hollow land wheel is provided with frame 1 standpipe 7 is installed, and the top of land wheel installation standpipe 7 is provided with the land wheel with screw rod
Height adjusting handle 8, screw rod penetrates land wheel and installs in standpipe 7, and land wheel is connected with land wheel installing arm 6, and land wheel installing arm 6 is inserted in ground
Wheel is installed in standpipe 7, and is connected with the screw flight.Height adjusting handle 8 is rotated, stretches out can land wheel installing arm 6
Or retraction land wheel is installed in standpipe 7, so as to realize the adjustable of the terrain clearance of frame 1.
