Description

Technical Field

[0001] This invention relates to the field of plant cultivation technology, specifically to a root cutting device for peach seedling cultivation. Background Technology

[0002] Pruning of peach tree roots generally refers to pruning the fibrous roots and lateral roots. During the cultivation and transplanting process of peach trees, the fibrous roots are in a dormant state during the soil establishment period. At this time, most fibrous roots cannot absorb water from the soil. Excessive fibrous roots increase the overall nutrient supply burden of the plant and reduce the survival rate of the peach tree. Therefore, it is necessary to prune the fibrous roots. During the cultivation of peach trees, the growth of lateral roots may cross with the main root to form intertwined roots. Pruning the intertwined roots of the lateral roots can also prevent them from affecting the normal growth of the main root and effectively increase the growth height of the main trunk of the peach tree.

[0003] In the prior art, such as the "Root Cutting Device for Peach Tree Seedling Cultivation" with Chinese Patent No. CN218337234U, there is a supporting base plate. A protective plate is fixedly installed on the top of the supporting base plate. A first hole is preset between the inner surface walls of the protective plate. A bearing is fixedly inserted between the inner surface walls of the first hole. A first drive rod is movably inserted between the inner surface walls of the bearing. A turntable is fixedly sleeved between the outer surface walls of the first drive rod. Multiple sets of threaded rods are fixedly installed on one side of the outer wall of the turntable. Multiple sets of limiting posts are fixedly installed on one side of the outer wall of the turntable.

[0004] However, in existing technologies, depending on the growth status of the peach tree during transplantation, the variety of the peach tree, and the soil environment of the cultivation environment, it is necessary to prune the fibrous roots of the peach tree to varying degrees. This is to ensure that the water absorption of the fibrous roots during the dormant period of soil establishment is matched with the number of fibrous roots retained. The blades of existing shearing blades have flat cutting surfaces, which cannot perform regular selection and pruning of fibrous roots. Instead, traditional methods are used to cut off some fibrous roots and leave others based on experience. This results in areas where the fibrous roots are too densely packed, leading to low water absorption and utilization rates in the new soil and affecting the survival rate of the peach tree. Summary of the Invention

[0005] The purpose of this invention is to provide a root cutting device for peach seedling cultivation, in order to solve the problem mentioned in the background art that the blade of the existing shearing blade has a flat cutting surface, which makes it impossible to regularly select and cut the fibrous roots. It can only cut off some of the fibrous roots and leave others based on experience in the traditional way. As a result, the areas where the fibrous roots are too densely packed have low water absorption and utilization rate in the new soil, which affects the survival rate of the peach trees.

[0011] Preferably, the top end of the cam is rotatably connected to a connecting shaft, the top end of the connecting shaft is fixedly connected to a sliding plate, the top end of the sliding plate is fixedly connected to a support rod, and both ends of the support rod are fixedly connected to second locking blocks. The side walls of the blade holder and the first blade are both provided with second straight grooves, and the second locking blocks are slidably connected to the second straight grooves.

[0012] Preferably, the positioning mechanism includes a first connecting frame, a cross rod, and a second connecting frame. A first positioning component is provided on the side wall of the first connecting frame. The first positioning component includes a first positioning cylinder, which is fixedly connected to the side wall of the first connecting frame.

[0013] Preferably, a first through rod is slidably connected to the inner side wall of the first positioning cylinder, a first rack is fixedly connected to one end of the first through rod, a first gear is meshed with the outer side wall of the first rack, and the first gear is fixedly connected to the outer side wall of the cross rod.

The second positioning component includes a second positioning cylinder, which is fixedly connected to the side wall of the second connecting frame, and a second through rod is slidably connected to the inner side wall of the second positioning cylinder.

[0016] Preferably, one end of the second through rod is fixedly connected to a second rack, the outer side wall of the second rack is slidably connected to a second limiting frame, a second bending rod is fixedly connected between the second limiting frame and the second connecting frame, a second gear meshes with the outer side wall of the second rack, the second gear is fixedly connected to the outer side wall of the cross rod, and the outer side wall of the second connecting frame is fixedly connected to the side wall of the support frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, the position of the frame rod is moved by manually adjusting the position of the dial, thereby changing the distance between the frame rod and the second blade. Since the hinge seat and the second blade are connected by a linkage rod, the linkage rod adjusts the position of the second blades connected to both sides until the cutting spacing of the second blade of the root cutting assembly is adjusted to a suitable root cutting density. This achieves the effect of controlling the density when cutting peach tree roots, making it easier to cut peach tree roots to different densities to adapt to the transplanting environment and improve the survival rate of transplanted peach trees.

[0019] 2. In this invention, by pushing the knob away from the second blade, the support rod is moved away from the second blade, thereby causing the hinge to pull the two linkage rods closer to the middle, causing multiple sets of second blades to close together and concentrate at the tail end of the blade holder. The hinge at the other end will drive the sliding rod to be pulled out from the cavity of the blade holder, causing the pointed conical surface of the third blade to move to the shearing area with the first blade, so that the lateral roots can achieve the function of shearing the root system through the cutting effect of the third blade and the first blade.

[0020] 3. In this invention, by setting the fibrous root cutting component at a position far from the rotation axis, the second blade obtains a longer lever arm, allowing the second blade to move further via the blade holder and use a wide range of root cutting actions. By setting the lateral root cutting component at a position close to the rotation axis, the lateral root cutting component obtains a larger compressive force with a smaller lever arm under the same pressure, so that the shearing force between the third blade and the first blade can completely cut off the lateral roots. This is suitable for cutting a small number of lateral roots with hard rhizomes.

[0021] 4. In this invention, the cam is driven to rotate continuously by the reduction motor. The cam drives the first locking block on the surface to move, so that the straight guide rail moves back and forth in a straight trajectory. The first sliding block drives the position of the rotating shaft to move, thereby causing the position of the support rod relative to the rotating shaft to change continuously. This causes the included angle between the first blade and the blade holder to change accordingly, so that the first blade and the blade holder are continuously cut and opened. The driving mechanism realizes the function of automatic shearing of peach tree roots.

[0022] 5. In this invention, by adjusting the position of the first through rod with a handle, the first through rod drives the first rack to move, and the first rack drives the first gear to rotate, controlling the orientation of the second connecting frame in a horizontal direction. Adjusting the length of the second through rod extending into the second positioning cylinder causes the second through rod to drive the second rack to move, and the second rack drives the second gear to rotate, adjusting the vertical orientation of the second connecting frame, thereby achieving the effect of positioning the shearing mechanism and facilitating the shearing of peach tree roots from various angles.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention. Example 1

[0036] according to Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown: A root cutting device for peach seedling cultivation includes a positioning mechanism 1, a driving mechanism 2, and a cutting mechanism 3. The cutting mechanism 3 includes a first blade 31, a rotating shaft 32, and a root cutting assembly 33. The root cutting assembly 33 includes a blade holder 331. The rotating shaft 32 is rotatably connected between the blade holder 331 and the first blade 31. A locking frame 333 is fixedly connected to the inner side wall of the blade holder 331. A second blade 332 is slidably connected to the inner side wall of the locking frame 333. A support rod 336 is provided on the outer side of the two second blades 332. A cavity is opened inside the blade holder 331. The support rod 336 is located inside the cavity of the blade holder 331. A hinge seat 338 is slidably connected to the outer side wall of the support rod 336. Two linkage rods 337 are rotatably connected to the hinge seat 338. The linkage rods 337 are rotatably connected to the side wall of the second blade 332.

[0037] A side root shearing assembly 35 is provided on one side of the second blade 332. The side root shearing assembly 35 includes a third blade 351. A collar 353 is fixedly connected to the outer side wall of the third blade 351. A sliding rod 352 is slidably connected to the inner side wall of the collar 353. The sliding rod 352 is fixedly connected to the hinge seat 338. A through groove 335 is opened on the outer side wall of the blade holder 331. A knob 334 is provided on the outer side of the through groove 335. A second sliding block 339 is fixedly connected between the knob 334 and the frame rod 336. The second sliding block 339 is slidably connected to the inner side wall of the through groove 335. The third blade 351 is slidably connected to the inner wall of the cavity of the first blade 31.

[0038] In this embodiment, when the roots of the peach tree are cut, the shearing motion between the root cutting components 33 of the first blade 31 is used. The first blade 31 achieves an auxiliary cutting effect during the cutting action. The first blade 31 is designed as a solid structure, while the root cutting components 33 have a cavity inside. The size of the root cutting components 33 is also larger than that of the first blade 31. The cut surfaces of the root cutting components 33 and the first blade 31 form two intersecting conical structures, thereby achieving the cutting of the root diameter between the root cutting components 33 and the first blade 31.

[0039] The root shearing assembly 33 is divided into two parts according to the shearing function. The first part is a shearing area for the rootlets composed of multiple second blades 332, and the second part is a shearing area for the lateral roots composed of a third blade 351. Since the rootlets are characterized by small, soft roots and a large number of roots, it is necessary to maintain the rootlets within a certain density range after transplanting and shearing during the shearing process. Therefore, it is necessary to control the shearing density of the rootlets by the second blades 332 and the first blade 31. The lateral roots are characterized by a relatively small number of roots and a thicker and harder rootlet. In order to make the shearing of the lateral roots by the root shearing assembly 33 and the first blade 31 more even, it is necessary to have sufficient force during the cutting process between the third blade 351 and the first blade 31. Therefore, the third blade 351 is designed to be close to the rotation axis 32, so as to obtain a larger pressing force under the same pressure with a smaller lever arm. This allows the shearing force between the third blade 351 and the first blade 31 to completely cut the lateral roots and reduce the damage to the peach tree roots caused by multiple shearings.

[0040] To control the density of root shearing and ensure that peach seedlings maintain a suitable root condition during transplanting to a new planting environment, a transverse groove 335 is provided on the outer side of the blade holder 331. A portable adjustable knob 334 is located on the outer side of the groove 335. A support rod 336, movable with the knob 334, is positioned within the internal cavity of the blade holder 331 at the location corresponding to the knob 334. The support rod 336 is connected to the knob 334 via a second sliding block 339. Multiple sets of second blades 332 are positioned above the support rod 336, and a hinge 338 is provided between two adjacent second blades 332. The hinge 338 can be adjusted by the support rod 336. The surface of 6 can slide freely, so that the hinge seat 338 and the second blade 332 are linked by the linkage rod 337. When the support rod 336 moves closer to the second blade 332, the two sets of linkage rods 337 will push the second blade 332 to both sides, causing the distance between the second blades 332 to increase. When the support rod 336 moves away from the second blade 332, the linkage rods 337 will pull the second blade 332 closer to the middle, causing the distance between the second blades 332 to decrease. The hinge seat 338 that slides at one end of the support rod 336 is in contact with the inner wall of the cavity of the blade holder 331. With the first hinge seat 338 as the support starting point, multiple sets of second blades 332 are either pushed open or pulled closer.

[0041] When adjusting the density of pruning roots to meet transplanting needs, the sliding knob 334 on the outside of the blade holder 331 is moved, causing the knob 334 to move the internal support rod 336. This causes the support rod 336 to move the hinge seat 338, thus changing the angle between the hinge seat 338 and the linkage rod 337. This controls the spacing of the second blade 332, adjusting the second blade 332 attached to the surface of the fibrous root cutting assembly 33 to a suitable state for cutting fibrous roots. When the third blade 351 is needed to cut lateral roots, the knob 334 is pushed away from the second blade 332, pulling the second blade 332 closer and retracting it into a narrow area. The hinge seat 338 at the other end will then drive the sliding rod 352 out of the cavity of the blade holder 331, causing the pointed conical surface of the third blade 351 to move to the cutting area with the first blade 31, so that the lateral roots can be cut in this area. Example 2

[0042] according to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the drive mechanism 2 includes a support frame 21 and a drive assembly 22. An annular frame 24 is fixedly connected to the top surface of the support frame 21. The drive assembly 22 includes a cam 221. The outer side wall of the cam 221 is rotatably connected to the inner side wall of the annular frame 24. A reduction motor 23 is fixedly connected above the top surface of the support frame 21. The output end of the reduction motor 23 is fixedly connected to the top surface of the cam 221. A directional guide rail 25 is fixedly connected to the outer side wall of the support frame 21. A first sliding block 26 is slidably connected to the inner side wall of the directional guide rail 25.

[0043] One end of the rotating shaft 32 is fixedly connected to the first sliding block 26. A straight guide rail 223 is fixedly connected to the outer wall of the first sliding block 26. A first locking block 226 is fixedly connected to the side wall of the straight guide rail 223. A first straight groove 228 is opened on the side wall of the straight guide rail 223. The first locking block 226 is slidably connected to the cam 221. A connecting shaft 222 is rotatably connected to the top of the cam 221. A sliding plate 225 is fixedly connected to the top of the connecting shaft 222. A support rod 224 is fixedly connected to the top of the sliding plate 225. A second locking block 227 is fixedly connected to both ends of the support rod 224. A second straight groove 34 is opened on the side wall of the blade holder 331 and the first blade 31. The second locking block 227 is slidably connected to the second straight groove 34.

[0044] In this embodiment, a power source drive mechanism 2 is provided below the shearing mechanism 3 to drive the first blade 31 and the root shearing assembly 33 to shear each other. A storage battery is provided inside the drive mechanism 2. A geared motor 23 is provided above the support frame 21. The storage battery continuously supplies power to the geared motor 23. A power switch for controlling the opening and closing of the root shearing assembly 33 is provided on the outer surface of the support frame 21. When shearing, the geared motor 23 drives the cam 221 to rotate continuously. The cam 221 drives the first locking block 226 on the surface to move. The surface of the cam 221 is provided with a curved groove. According to the movement trajectory of the curved groove, it can be converted into the reciprocating linear movement of the first locking block 226. The straight guide rail 223 fixed on the outside of the first locking block 226 also moves along a straight trajectory. The straight guide rail 223 drives the first sliding block 26 connected to the tail end to move, so that the first sliding block 26 drives the position of the rotating shaft 32 to move.

[0045] Meanwhile, since the position of the connecting shaft 222 remains unchanged, the position of the sliding plate 225 relative to the support frame 21 is fixed, which makes the position of the strut 224 relative to the support frame 21 remain unchanged, and thus the position relative to the rotating shaft 32 keeps changing. Since the lengths connected at both ends of the strut 224 remain unchanged, the strut 224 supports the first blade 31 and the blade holder 331. When the position of the rotating shaft 32 changes, the angle between the first blade 31 and the blade holder 331 also changes, thereby causing the first blade 31 and the blade holder 331 to continuously cut and open, thus achieving the effect of shearing the fibrous roots. Example 3

[0046] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the positioning mechanism 1 includes a first connecting frame 11, a cross rod 15, and a second connecting frame 16. A first positioning component 12 is provided on the side wall of the first connecting frame 11. The first positioning component 12 includes a first positioning cylinder 121, which is fixedly connected to the side wall of the first connecting frame 11. A first through rod 122 is slidably connected to the inner side wall of the first positioning cylinder 121. A first rack 123 is fixedly connected to one end of the first through rod 122. A first gear 125 meshes with the outer side wall of the first rack 123. The first gear 125 is fixedly connected to the outer side wall of the cross rod 15. A first limiting frame 124 is slidably connected to the outer side wall of the first rack 123. A first bending rod 126 is fixedly connected between the first limiting frame 124 and the first connecting frame 11. A support plate frame 14 is fixedly connected to the bottom end of the first connecting frame 11.

[0047] Both ends of the cross rod 15 are rotatably connected to the first connecting frame 11, and the other two ends of the cross rod 15 are rotatably connected to the second connecting frame 16. The side wall of the second connecting frame 16 is provided with a second positioning component 13. The second positioning component 13 includes a second positioning cylinder 131. The second positioning cylinder 131 is fixedly connected to the side wall of the second connecting frame 16. The inner side wall of the second positioning cylinder 131 is slidably connected to a second through rod 132. One end of the second through rod 132 is fixedly connected to a second rack 133. The outer side wall of the second rack 133 is slidably connected to a second limiting frame 134. The second limiting frame 134 and the second connecting frame 16 are fixedly connected to a second bending rod 136. The outer side wall of the second rack 133 is meshed with a second gear 135. The second gear 135 is fixedly connected to the outer side wall of the cross rod 15. The outer side wall of the second connecting frame 16 is fixedly connected to the side wall of the support frame 21.

[0048] In this embodiment, since the lateral roots of the same peach tree are pointing upwards differently, in order to cut the lateral roots of the peach tree at different angles upwards, the peach tree is suspended above the cutting mechanism 3 using a frame. The other end of the first through rod 122 passes through the first positioning cylinder 121 and is connected to a handle. The handle is used to adjust the position of the first through rod 122 extending into the first positioning cylinder 121, thereby causing the first through rod 122 to drive the first rack 123 to move, causing the first rack 123 to drive the first gear 125 to rotate, causing the first gear 125 to drive the position of the connected cross rod 15, thereby controlling the orientation of the second connecting frame 16 in a horizontal plane. Furthermore, since the first bending rod 126 connects the first limiting frame 124 and the first connecting frame 11, the first rack 123 and the first gear 125 always remain in a meshed state during rotation.

[0049] The other end of the second through rod 132 passes through the second positioning cylinder 131 and is also connected to a handle. By using the handle to adjust the length of the second through rod 132 extending into the second positioning cylinder 131, the second through rod 132 drives the second rack 133 to move, and the second rack 133 drives the second gear 135 to move, causing the second gear 135 to drive the cross rod 15 to rotate, so that the second connecting frame 16 deflects relative to the cross rod 15 in the vertical direction, thereby adjusting the vertical orientation of the second connecting frame 16 and achieving a comprehensive cutting effect on all positions of the shearing mechanism 3 and the peach tree root system.

[0050] The usage and working principle of this device are as follows: First, the peach tree is suspended above the shearing mechanism 3 using the frame. The position of the first through rod 122 is adjusted using the handle, so that the first through rod 122 drives the first rack 123 to move. The first rack 123 drives the first gear 125 to rotate, controlling the orientation of the second connecting frame 16 in a horizontal direction. The position of the second through rod 132 is adjusted using the other handle, so that the second through rod 132 drives the second rack 133 to move. The second rack 133 drives the second gear 135 to move, adjusting the vertical orientation of the second connecting frame 16, aligning the first blade 31 and the root shearing assembly 33 with the peach tree roots.

[0051] Then, slide the dial 334, causing the dial 334 to move the frame rod 336 through the second sliding block 339. The distance between the frame rod 336 and the second blade 332 changes. Since the second blade 332 and the frame rod 336 are connected through the linkage rod 337, the spacing of the second blade 332 changes. Adjust the ratio of the cutting part and the gap part of the second blade 332 so that the cutting density required by the peach tree roots is matched with the spacing of the second blade 332 on the root cutting assembly 33.

[0052] Subsequently, the reduction motor 23 is started, which drives the cam 221 to rotate. The cam 221 drives the first locking block 226 on the surface to move, causing the first locking block 226 to drive the straight guide rail 223 to move back and forth in a straight line. The straight guide rail 223 drives the first sliding block 26 connected to the tail end to move. The first sliding block 26 drives the position of the rotating shaft 32 to move, which changes the distance between the support rod 224 and the rotating shaft 32. The position of the first blade 31 and the blade holder 331 connected to the support rod 224 changes. When the position of the rotating shaft 32 changes, the included angle between the first blade 31 and the blade holder 331 also changes. The first blade 31 and the blade holder 331 continuously cut and open, and cut the root hairs.

[0053] During the process of cutting new fibrous roots, the handle is used to continuously adjust the orientation of the second connecting frame 16 in the horizontal plane and in the vertical direction, so that the cutting mechanism 3 overlapping on the outside of the second connecting frame 16 can connect with the new fibrous roots until all the fibrous roots of the peach tree are completely cut off.

[0054] During the pruning of the lateral roots of the peach tree, the knob 334 is pushed away from the second blade 332, so that the second blade 332 is completely retracted at the tail end of the blade holder 331. The hinge seat 338 at the other end will drive the sliding rod 352 to be pulled out from the cavity of the blade holder 331, causing the pointed conical surface of the third blade 351 to move to the pruning area with the first blade 31, and the lateral roots of the peach tree are placed in this area for pruning.

[0055] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
