Abstract
Description
Technical Field
[0001] This invention relates to the field of peony division technology, specifically to a rapid cutting device and method for peony division. Background Technology
[0002] Peony is a perennial herbaceous plant belonging to the genus Paeonia in the family Paeoniaceae. It is also known as wild peony, native white peony, and peony flower. It has a stout root with dark brown branches; the stem is hairless; the leaflets are narrowly ovate, elliptic, or lanceolate; the flowers grow at the top of the stem and in the leaf axils; the flowering period is from May to June, and the fruiting period is in August.
[0003] Peony division is a common method for propagating and renewing plants. The best time is usually in autumn, specifically from early September to late October, when the temperature is suitable (daily average 15℃~25℃) and the soil temperature is higher than the air temperature, which is conducive to wound healing and new root sprouting.
[0004] During the division and processing of peony plants, a cutting device is needed to cut the peony. When cutting, divide along the natural texture of the root system. Each plant should retain 3-5 plump buds and more than 3 thick fleshy roots (each about 15-20 cm long). After division, let the plant dry the wounds in a cool and ventilated place for 1-2 days, or apply charcoal powder, rooting powder, etc. to prevent decay and promote healing. If the roots are fragile, they can be dried first before division, and then planted.
[0005] Chinese patent application CN113973529A discloses a rapid division device and method for peony plants, including an operating table with several mud-leaking holes at the front end and a pad in the center of the area where the mud-leaking holes are located; a feeding and discharging conveyor, one on the left and one on the right of the operating table; a clamping mechanism, which is located on the left and right sides of the pad to clamp the peony roots in a left-right clamping manner; and a cutting unit, which includes a lifting cylinder fixed to the operating table, a horizontal arm fixed to the piston rod of the lifting cylinder, and a cutting mechanism fixed to the horizontal arm. Under the action of the lifting cylinder, the cutting mechanism moves downward to cut the peony roots, and the cutting mechanism is located above the pad.
[0006] In use, remove the peony from the feeding conveyor, place it on the pad, adjust the angle of the peony, and clamp it with the clamping mechanism. Then, start the cutting unit to cut and divide the peony roots. After the first cutting, the peony roots can be divided again, ensuring that each peony plant has three to four buds. After division, place the peony roots on the discharge conveyor.
[0007] In the above technology, the two sliders move closer to each other, thereby driving the six clamping rods set on the left and right to clamp the roots of the peony. However, the clamping adaptability is poor. When the clamping rods are inserted into the peony, they are prone to colliding with the peony buds, causing damage to the peony buds and affecting the survival rate of the peony. Summary of the Invention

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0030] Reference Figures 1-6The present invention discloses a rapid cutting device for peony division, comprising a workbench 1 and a cutting mechanism 2 disposed on the workbench 1. The cutting mechanism 2 is used to cut and process peonies. A clamping mechanism 3 is disposed on the workbench 1 to fix and clamp the peonies. The cutting mechanism 2 is located directly above the clamping mechanism 3. When processing peonies, the peonies are first placed at the clamping mechanism 3 (the peonies are placed vertically), and the two sides of the peonies are fixed and clamped by the clamping mechanism 3. Then the cutting mechanism 2 is activated to cut the peonies, thereby realizing the division of peonies.
[0031] Reference Figure 1 and Figure 2 The cutting mechanism 2 includes a support frame 21 fixedly installed on the workbench 1 and a cutting assembly 22 set on the support frame 21 for cutting peonies. The cutting assembly 22 includes a cutting blade 221 for cutting peonies and a driver 222 fixedly installed on the support frame 21 for driving the cutting blade 221 to slide. The driver 222 is vertically set and directly uses a cylinder. The piston rod of the driver 222 is detachably connected to the cutting blade 221. The cutting blade 221 is vertically set and the bottom end of the cutting blade 221 is set as a pointed tip with a tip angle of 30°-60° to reduce resistance during cutting and avoid root and stem tearing.
[0032] Reference Figure 2 , Figure 3 and Figure 4 The clamping mechanism 3 includes multiple clamping frames 31 that slide on the worktable 1 and multiple clamping rods 32 that are set on the clamping frames 31. There are two clamping frames 31, which are arranged opposite each other. Each clamping frame 31 is provided with five clamping rods 32. The five clamping rods 32 are located at the five corners of a regular pentagon, forming a plum blossom-shaped clamping layout. The five clamping rods 32 are arranged in a "2-2-1" pattern along the vertical downward direction, that is, two in the upper layer, two in the middle layer, and one in the lower layer. The upper and middle layer clamping rods 32 are used to fix the upper and middle parts of the rootstock. The clamping frame 31 is provided with a sliding groove 311. The sliding groove 311 is set as a T-shaped groove. The sliding groove 311 is arranged along the radial direction of the peony. The clamping rods 32 slide on the sliding groove 311 of the clamping frame 31 along the horizontal direction.
[0033] Among them, reference Figure 2 , Figure 3 and Figure 5The clamping rod 32 includes a sliding part 321 that is slidably fitted on the clamping frame 31, a telescopic part 322 that is slidably fitted on the sliding part 321 along the radial direction of the peony, and an elastic element 323 for pushing the telescopic part 322 to slide away from the sliding part 321. The telescopic part 322 is sleeved on the sliding part 321, and the end of the telescopic part 322 away from the clamping frame 31 is provided with an arc-shaped surface. The elastic element 323 is directly a spring. One end of the elastic element 323 is fixedly connected to the telescopic part 322, and the other end is fixedly connected to the sliding part 321. When multiple clamping rods 32 are inserted into the peony, the clamping rods 32 can slide horizontally and telescopically to make room for adjustment.
[0034] Reference Figure 2 , Figure 3 and Figure 4 The sliding part 321 is provided with a sliding mechanism 4. The sliding mechanism 4 includes a slider 41 fixedly disposed on the sliding part 321 and an elastic element 42 for pushing the slider 41 to slide and reset. The slider 41 is a T-shaped block and slides in the groove 311. The elastic element 42 is directly a spring. One end of the elastic element 42 is fixedly connected to the slider 41 and the other end is fixedly connected to the clamping frame 31.
[0035] Reference Figure 3 , Figure 4 and Figure 5 The clamping frame 31 is equipped with a support mechanism 5 for supporting the bottom of the peony. The support mechanism 5 includes a support sleeve 51 for supporting the bottom of the peony and a support assembly 52 for supporting the support sleeve 51. The side of the support sleeve 51 away from the clamping frame 31 is set as an arc surface. The side of the support sleeve 51 away from the clamping frame 31 can protrude from the side of the telescopic part 322 away from the clamping frame 31. In the clamping state, there can be a gap of 3-5mm between the two telescopic parts 322 arranged opposite to each other along the length direction of the worktable 1, which is for the cutting blade 221. By providing space, two support sleeves 51 arranged opposite to each other along the length of the workbench 1 abut together; the support assembly 52 includes a fixed plate 521 and an elastic element 522 fixedly mounted on the clamping frame 31. The support sleeve 51 is slidably fitted to the fixed plate 521. The elastic element 522 is directly a spring. One end of the elastic element 522 is fixedly connected to the fixed plate 521, and the other end is fixedly connected to the support sleeve 51, and is used to drive the support sleeve 51 to slide away from the fixed plate 521.
[0036] Reference Figure 2 , Figure 3 and Figure 4The workbench 1 is provided with an adjustment mechanism 6. The adjustment mechanism 6 includes an adjustment block 61 for moving multiple clamping frames 31 closer to or further away from each other and a drive assembly 62 for driving the adjustment block 61 to slide. The adjustment block 61 is a T-shaped block. The adjustment block 61 is fixedly connected to the fixing plate 521 on the clamping frame 31. The adjustment block 61 is slidably engaged with the workbench 1.
[0037] Among them, reference Figure 2 , Figure 3 and Figure 4 The drive assembly 62 includes a screw 621 threaded into the adjusting block 61 and a drive component 622 for rotating the screw 621. The screw 621 is a bidirectional screw, and the drive component 622 is directly an electric motor. The cylinder of the drive component 622 is fixedly mounted on the worktable 1. The output shaft of the drive component 622 is fixedly connected to the screw 621. The screw 621 is used to drive the two clamping frames 31 to slide towards or away from each other.
[0038] Reference Figure 1 and Figure 2 A rotating device 7 is provided on the output end of the driver 222. The rotating device 7 is used to adjust the cutting angle of the cutting blade 221. The rotating device 7 includes a fixed frame 71 and a rotating assembly 72, which are fixedly installed on the output end of the driver 222. The fixed frame 71 has an arc-shaped structure. The rotating assembly 72 includes a second driving component 721 fixedly installed on the fixed frame 71, a gear 722 fixedly installed on the output shaft of the second driving component 721, and a rack 723 meshing with the gear 722. The second driving component 721 is directly driven by an electric motor. The rack 723 is slidably engaged with the fixed frame 71. The top end of the cutting blade 221 is fixedly connected to the rack 723. When the second driving component 721 is started, it can drive the gear 722 to rotate. When the gear 722 rotates, it drives the rack 723 to slide along the fixed frame 71, thereby driving the cutting blade 221 to rotate and adjust, thus realizing the adjustment of the cutting angle of the cutting blade 221, which can meet the needs of multi-angle cutting of peony.
[0039] The implementation principle of the peony division and rapid cutting device of the present invention is as follows: When processing peonies, firstly, according to the approximate size of the peony rootstock to be divided, the driving component 622 is activated. The driving component 622 drives the screw 621 to rotate, which drives the adjusting block 61 to slide. The adjusting block 61 drives the two clamping frames 31 to slide in a direction away from each other, leaving enough space for placement. Then, the peony rootstock is placed on the support sleeve 51 between the two clamping frames 31 (the peony rootstock part is located on the support sleeve 51). Under the action of the elastic component 522, the support sleeve 51 lifts the rootstock upward, so that the center of the rootstock is aligned with the cutting blade 221. Then, the drive unit 622 is activated. The drive unit 622 drives the screw 621 to rotate, which in turn drives the two adjusting blocks 61 to slide. The two adjusting blocks 61 drive the two fixing plates 521 to slide in a direction that brings them closer to each other. The two fixing plates 521 drive the two clamping frames 31 to slide in a direction that brings them closer to each other. The clamping frames 31 drive multiple clamping rods 32 and support sleeves 51 to slide. The clamping rod 32 gradually approaches the peony root and inserts into it (avoiding damage to the buds). When the clamping rod 32 contacts the root, if the root is irregular in size or has branches, the sliding part 321 slides in the groove 311 through the slider 41. When the groove 311 slides, the elastic element 42 deforms, and at the same time, the telescopic part 322 expands and contracts under the action of the elastic element 323, automatically making room for adjustment. Finally, multiple clamping rods 32 adhere to the surface of the root from different directions and are inserted into the peony, achieving a stable clamping of the peony. After the peony is fixed and clamped, the cutting mechanism 2 is started. The driver 222 drives the cutting blade 221 to descend smoothly. The cutting blade 221 precisely cuts the peony rootstock to achieve separation. During the cutting process, the elastic adjustment of the clamping rod 32 and the bottom support of the support sleeve 51 together restrict the displacement of the rootstock to ensure a flat cut. At the same time, when the cutting blade 221 passes between multiple clamping rods 32, it can pass through the gap between two telescopic parts 322 that are arranged opposite to each other along the length of the worktable 1. When the cutting blade 221 passes between two clamping rods 32 and reaches the two support sleeves 51, the tip of the cutting blade 221 can be inserted into the top of the two support sleeves 51 to achieve complete severing of the peony. After the peony is cut, the drive unit 622 is activated. The drive unit 622 drives the screw 621 to rotate, which in turn drives the adjusting block 61 to slide. The adjusting block 61 drives the two clamping frames 31 to slide in a direction away from each other, so that the cut peony can be removed for further processing.
[0040] When peony needs to be cut at multiple angles, drive component 2 721 is activated, which drives gear 722 to rotate. When gear 722 rotates, it drives rack 723 to slide along fixed frame 71, thereby driving cutter 221 to rotate and adjust, thus realizing the adjustment of cutting angle of cutter 221. Then, cutting mechanism 2 is activated, drive 222 to drive cutter 221 to descend smoothly, and cutter 221 precisely cuts peony rootstock.
[0041] Reference Figures 1-6 The present invention also provides a method for rapid cutting of peony divisions, which includes the following steps: Peony clamping: Based on the approximate size of the peony rhizomes to be divided, the drive assembly 62 drives the screw 621 to rotate, causing the adjusting block 61 to slide. The adjusting block 61 causes the two clamping frames 31 to slide away from each other, leaving sufficient space for placement. Then, the peony rhizomes are placed on the support sleeve 51 between the two clamping frames 31 (the peony rhizome part is located on the support sleeve 51). Under the action of the elastic element 522, the support sleeve 51 lifts the rhizome upward, aligning the center of the rhizome with the cutting blade 221. Then, the drive assembly 62 is activated, which drives the two clamping frames 31 to slide towards each other. The clamping rod 32 gradually approaches the peony root and inserts into it (to avoid damaging the buds). When the clamping rod 32 contacts the root, if the root is irregular in size or has branches, the sliding part 321 slides in the groove 311 through the slider 41, and the telescopic part 322 extends and retracts under the action of the elastic element 323, automatically making room for adjustment. Finally, multiple clamping rods 32 adhere to the root surface from different directions to achieve a stable clamping. Peony cutting: Start the cutting mechanism 2. The driver 222 drives the cutting blade 221 to descend smoothly and accurately cut the peony rootstock to achieve plant division. During the cutting process, the elastic adjustment of the clamping rod 32 and the bottom support of the support sleeve 51 together restrict the displacement of the rootstock to ensure a flat cut.
