Specific implementation method:

[0030] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0031] Embodiment 1:

[0032] like Figure 1-3 As shown, a rotary orchard root cutting mechanism includes a lifting mechanism, a stretching mechanism, a rotating mechanism, a lifting mechanism and a cutter disc root cutting mechanism, wherein the lifting mechanism is connected to the stretching mechanism, the stretching mechanism is respectively connected to the rotating mechanism and the lifting mechanism, and the lower end of the lifting mechanism is also connected to the cutter disc root cutting mechanism.

[0033] Embodiment 2:

[0034] A rotary orchard root cutting mechanism, the lifting mechanism includes a first frame 1, a first lifting cylinder 2, a lifting arm 3, a second lifting cylinder 4, a second frame 13 and a transition frame 30, one end of the first frame 1 is respectively connected to the lifting arm 3 and the second frame 13 through an intermediate bracket 29, wherein the intermediate bracket 29 is hingedly connected to the lifting arm 3, the intermediate bracket 29 is hingedly connected to the first frame 1, the upper end of the first frame 1 is hingedly connected to one end of the first lifting cylinder 2, the transition frame 30 is respectively hingedly connected to the other end of the first lifting cylinder 2, one end of the second lifting cylinder 4 and the lifting arm 3, and the other end of the second lifting cylinder 4 is also hingedly connected to the extension guide rail 14 in the extension mechanism.

[0035] The rodless chamber A port of the first stage lifting oil cylinder 2 and the rod chamber D port of the second stage lifting oil cylinder 4 are connected to the hydraulic system control valve, and the rod chamber B port and the rodless chamber C port are connected in series with an oil pipe, so that the first stage lifting oil cylinder 2 and the second stage lifting oil cylinder 4 can move in the same direction at the same time. When oil enters the A port, the first stage lifting oil cylinder 2 and the second stage lifting oil cylinder 4 are deployed at the same time, and the first frame 1 descends. When the first stage lifting oil cylinder 2 and the second stage lifting oil cylinder 4 are fully deployed, the distance between the blade and the lower plane of the first frame 1 is 1100mm. Fig.12 As shown, when oil is introduced into the D port, the first stage lifting cylinder 2 and the second stage lifting cylinder 4 are simultaneously retracted, and the first frame 1 rises. When the first stage lifting cylinder 2 and the second stage lifting cylinder 4 are fully retracted, the blade is 380mm away from the lower plane of the first frame 1, which is convenient for transportation and operation. Fig.13 shown.

[0036] like Figure 4As shown, the extension mechanism includes a first extension cylinder 12, a second extension cylinder 35, an extension guide rail 14, a first extension arm 15 and a second extension arm 32. The extension guide rail 14 is a hollow structure, which is a hollow square tube. The outer end surface of the extension guide rail 14 is welded to the second frame 13, and the extension guide rail 14 is provided with a first limiting groove 28 and a fourth ear plate 22. The first extension arm 15 and the second extension arm 32 are slidably installed in the extension guide rail 14. The end of the first extension arm 15 extending out of the extension guide rail 14 is provided with a third ear plate 23, and the end of the second extension arm 32 extending out of the extension guide rail 14 is provided with a seventh ear plate 34. The fourth ear plate 22 is connected to the third ear plate 23 by the second extension cylinder 35, and the fourth ear plate 22 is connected to the seventh ear plate 34 by the first extension cylinder 12.

[0037] The first extension arm 15 and the second extension arm 32 can slide relatively easily in the extension guide rail 14. When the cylinder rod of the first extension cylinder 12 or the second extension cylinder 35 is extended, the second extension arm 32 or the first extension arm 15 is translated outwardly, and the maximum translation distance is 250 mm. Fig.14 shown.

[0038] like Figure 4 As shown, the rotating mechanism includes two rotating arms 16, a first rotating cylinder 11, a second rotating cylinder 31, a second ear plate 25, an eighth ear plate 36 and two first ear plates 21. The first extension arm 15 is extended out of the extension guide rail 14 and has a second limiting groove 33 on the round tube, and the second extension arm 32 is extended out of the extension guide rail 14 and has a third limiting groove 37 on the round tube. The two rotating arms 16 are respectively installed in the round tubes of the first extension arm 15 and the second extension arm 32. The second ear plate 25 passes through the second limiting groove 33 and is welded to one rotating arm 16. The eighth ear plate 36 passes through the third limiting groove 37 and is welded to the other rotating arm 16. The two first ear plates 21 pass through the first limiting groove 28 and are respectively welded to the first extension arm 15 and the second extension arm 32. One of the first ear plates 21 and the second ear plate 25 are connected by the second rotating cylinder 31, and the other first ear plate 21 and the eighth ear plate 36 are connected by the first rotating cylinder 11.

[0039] When the first rotary cylinder 11 or the second rotary cylinder 31 contracts, Fig.10 As shown, when the first rotary cylinder 11 or the second rotary cylinder 31 is extended, as shown in Fig.11 As shown, the maximum deflection angle of the cutter disc 6 and the travel direction include an angle of 20°.

[0040] The first ear plate 21 is welded to the square tube of the first extension arm 15 and the second extension arm 32 within the range of the first limiting groove 28, and ensures that when the first extension arm 15 and the second extension arm 32 move outward by 250 mm, the first ear plate 21 contacts the boundary of the first limiting groove 28 to block the first extension arm 15 or the second extension arm 32 from continuing to move outward, thereby playing a limiting role and preventing the first extension arm 15 or the second extension arm 32 from detaching from the extension guide rail 14. When the second ear plate 25 or the eighth ear plate 36 rotates with the rotating arm 16, the left and right sides of the second ear plate 25 or the eighth ear plate 36 contact the boundary of the second limiting groove 33 or the third limiting groove 37 to block the rotating arm 16 from continuing to rotate. Figure 4 Shown by the dashed line.

[0041] The lifting mechanism is provided at two locations, which are symmetrically arranged on the rotating arms 16 at the left and right locations. Figure 5 As shown, the lifting mechanism includes a lifting arm 17, a lifting cylinder 18 and a cutter head guard fixing plate 19. The lifting arm 17 can be slidably installed in the rotating arm 16 up and down. The side of the rotating arm 16 is also provided with a fourth limiting groove 38. The cutter head guard fixing plate 19 passes through the fourth limiting groove 38 and is welded to the lifting arm 17. When the lifting arm 17 moves downward, the cutter head guard fixing plate 19 can only move within the range of the fourth limiting groove 38, that is, when the cutter head guard fixing plate 19 moves downward 400 mm with the lifting arm 17, the lower side surface of the cutter head guard fixing plate 19 contacts the boundary of the fourth limiting groove 38 to prevent it from continuing to move, thereby playing a limiting role to prevent the lifting arm 17 from separating from the rotating arm 16. The lower end of the second ear plate 25 is welded with a fifth ear plate 26. The lower end of the lifting arm 17 extending out of the rotating arm 16 is provided with a bearing seat 39. The outer side of the bearing seat 39 is provided with a sixth ear plate 27. The fifth ear plate 26 and the sixth ear plate 27 are hingedly connected by the lifting cylinder 18.

[0042] When the rod of the lifting cylinder 18 is extended, the lifting arm 17 moves downward. Due to the limiting effect of the cutter head guard fixing plate 19, the lifting arm 17 has a stroke of 400 mm. Fig.14 As shown, it is ensured that the lifting arm 17 will not fall off from the rotating arm 16.

[0043] The cutter root cutting mechanism is provided at two locations, which are arranged on the lifting mechanisms at the left and right locations respectively. Figure 6 As shown, the cutter head root cutting mechanism includes a cutter head connecting plate 9 and a cutter head 6. One end of the cutter head connecting plate 9 is connected to the cutter head 6, and the other end passes through the bearing seat 39 at the lower end of the lifting arm 17 and is connected to the hydraulic motor 10. In order to ensure that the hydraulic motor 10 is not worn by the ground during the root cutting operation, a hydraulic motor shield 7 is provided on the outside of the hydraulic motor 10. The hydraulic motor 10 is connected to the hydraulic system control valve through a hydraulic oil pipe, and the cutter head 6 is connected to the cutter head connecting plate 9 through bolts.

[0044] The upper end of the rotating arm 16 is welded with a cover plate 24. After the cover plate 24 is welded, the rotating arm 16 can flexibly rotate within the first extension arm 15 and the second extension arm 32 to prevent the rotating arm 16 from falling off from below the first extension arm 15 and the second extension arm 32. Figure 8 shown.

[0045] A cutter head guard 5 is provided above the cutter head 6, the upper end of the cutter head guard 5 is connected to the cutter head guard fixing plate 19 by bolts, and the lower end is connected to one end of the cutter head guard bracket 8 by bolts, and the other end of the cutter head guard bracket 8 is connected to the cutter head guard bracket fixing plate 20, and the cutter head guard bracket fixing plate 20 is installed on the bearing seat 39, as shown in FIG. Figure 7 and Fig. 9 shown.

[0046] The blade guard 5 can move simultaneously with the blade 6. No matter the blade 6 moves outward, descends, or deflects, the blade guard 5 can move simultaneously to ensure a good soil covering effect. The blade 6 is provided with 10 blades, with a thickness of 8mm, a cutting width of 64mm, and a diameter of 1218mm. Since the stroke of the lifting arm 17 is 400mm, the effective root cutting depth of the present invention is 400mm. The other parts are the same as those of Example 1.

[0047] The first frame 1 in the present invention can be connected to a tractor or other traction machinery to drive the present invention to work. (The vehicle travel direction is taken as the front, the right side is the right side of the vehicle, and the left side is the left side of the vehicle).

[0048] like Fig.12 This is a working state view of the present invention. At this time, hydraulic oil enters the rodless chamber A of the first-stage lifting cylinder 2, and the cylinder rods of the first-stage lifting cylinder 2 and the second-stage lifting cylinder 4 are in an extended state. The hydraulic valve controls the first extension cylinder 12 and the lifting cylinder 18 on the same side to extend. At this time, the cutter head 6 translates 250mm outward and drops 400mm. Then the hydraulic control valve is operated to rotate the hydraulic motor 10 on the same side to complete the root cutting work. When encountering roots that cannot be cut, the first rotating cylinder 11 or the second rotating cylinder 31 can be controlled to extend and retract to adjust the direction of the cutter head 6. The maximum angle between the cutter head 6 and the forward direction is 20°. Figure 10-11 As shown, when the present invention needs to be transported and transferred, oil enters the rod cavity D port of the second-stage lifting cylinder 4, and the first-stage lifting cylinder 2 and the second-stage lifting cylinder 4 are simultaneously retracted, as shown in FIG. Fig.13 As shown, the distance between the blade and the first rack 1 should not be greater than 380 mm.
