Description

Technical Field

[0001] The invention relates to the technical field of forest seedling cultivation, and in particular to a seedling cutting propagation device. Background Art

[0002] In the field of seedling breeding, cutting propagation, as an efficient asexual propagation technology, is widely used in large-scale cultivation of economic forests, ornamental seedlings, etc. Existing seedling cutting devices mostly borrow the mechanical structure of transplanters. Their core working principle is: through a hydraulically or pneumatically driven swing arm mechanism, a "duckbill"-shaped closed box is driven to insert into the soil. After the box reaches the preset depth, the control mechanism drives the duckbill box to open and lift the box at the same time, so that the cutting branches pre-placed in the box fall into the soil by gravity, completing the cutting operation.

[0003] However, this type of device has obvious defects in actual application: first, the overall structure is bulky, and the combination of the swing arm and the duckbill box takes up a lot of space on the mobile vehicle body, which can easily lead to low space utilization, especially in small work vehicles or multi-equipment collaborative work scenarios, limiting the integrated installation of other seedling auxiliary equipment (such as watering and fertilizing devices); second, the modular adaptability is poor, and the devices are mostly customized in design, and are insufficiently compatible with different models of mobile vehicles, seedling racks and other equipment. It is difficult to flexibly disassemble, replace or expand functions according to operational requirements, which increases the cost of equipment modification and maintenance; third, the cutting accuracy is limited by the structure. During the opening and closing process of the duckbill box, the branches are easily offset due to inertia, and when inserted into the soil in a closed state, it is easy to cause excessive squeezing of the surrounding soil, resulting in inconsistent cutting depth, branch tilting and other problems, which directly affect the rooting survival rate of seedlings. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To this end, the purpose of the present invention is to propose a seedling cutting propagation device. The present invention has a reasonable structure. By integrating core components such as the material rack and the lifting seat into the cutting box, the large swing arm is eliminated, and the space occupancy is greatly reduced. It is convenient for modular integration with equipment such as watering and fertilizing, and the space utilization rate of the mobile vehicle body is improved. The various components are detachably connected to adapt to different vehicle bodies and branch sizes, reducing the cost of modification and maintenance; multiple groups of U-shaped placement grooves are used to achieve stable positioning of branches, and the material rack flipping and pressure rod pushing are coordinated to ensure the verticality of the cuttings, reduce soil extrusion and branch deviation, and the cutting depth error is small, which improves the survival rate. The power mechanism and the automatic feeding design of the material guide seat reduce manual intervention, and the efficiency of single-plant cuttings is significantly improved, efficiently meeting the needs of large-scale seedling cultivation.

[0034] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention and are not to be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0035] A seedling cutting propagation device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0036] like Figures 1-6 As shown, a seedling cutting propagation device according to an embodiment of the present invention includes:

[0037] Cutting box 1: The bottom is provided with an opening, the surface is provided with a strip groove 2, and the inner wall is symmetrically provided with an axle seat 3, which is located outside the strip groove 2;

[0038] The material rack 4 is obliquely arranged inside the cutting box 1, and one end thereof passes through the outside of the cutting box 1 through the strip groove 2. The central axis of the material rack 4 is rotatably connected to the inner wall of the shaft seat 3, and a torsion spring is provided between the inner wall of the shaft seat 3. The top of the material rack 4 is provided with a first U-shaped placement groove 5. The cutting branch 6 is located in the first U-shaped placement groove 5 and is in contact with the inner wall of the cutting box 1 away from the strip groove 2.

[0039] Lifting seat 7: vertically slidably connected to the inner wall of the cutting box 1, and located on the top side of the material rack 4. The bottom of the lifting seat 7 is integrally formed with a tapered portion 8 that is consistent with the initial angle of the material rack 4. The lifting seat 7 is close to the side surface of the strip groove 2 and the bottom of the tapered portion 8. A second U-shaped placement groove 9 and a third U-shaped placement groove 10 that are adapted to the outer dimensions of the first U-shaped placement groove 5 are respectively provided, and are connected to each other. The inner wall of the upper end of the second U-shaped placement groove 9 is threadedly connected to a column seat 11, and the inner wall of the column seat 11 is vertically slidably connected to a pressure rod 12, and a spring is fixedly connected to the inner wall of the column seat 11.

[0040] It should be noted that the torsion spring and spring described in this embodiment are not shown in the figure.

[0041] It should also be noted that a rubber pad (not shown in the figure) is provided at the bottom of the pressure rod 12 described in this embodiment to prevent the cutting branches 6 from being crushed.

[0042] It should also be noted that the cutting box 1 described in this embodiment is fixedly connected to the mobile vehicle body, and an annular soil-breaking blade is provided on the outer surface of the cutting box 1 close to the strip groove 2, and is located on the bottom side of the strip groove 2. The cutting edge of the soil-breaking blade is inclined downward, and the soil is broken by the soil-breaking blade to reduce the resistance to cutting.

[0043] Specifically, the present invention has a reasonable structure. By integrating core components such as the material rack 4 and the lifting seat 7 into the cutting box 1, the large swing arm is eliminated, the space occupancy is greatly reduced, and it is convenient for modular integration with equipment such as watering and fertilizing, thereby improving the space utilization rate of the mobile vehicle body. The various components are detachably connected to adapt to different vehicle bodies and branch sizes, thereby reducing the cost of transformation and maintenance. Multiple groups of U-shaped placement grooves are used to achieve stable positioning of branches. The flipping of the material rack 4 and the pushing of the pressure rod 12 are coordinated to ensure the verticality of the cuttings, reduce soil extrusion and branch deviation, and have a small error in the cutting depth, thereby improving the survival rate. The automatic feeding design of the power mechanism 13 and the material guide seat 100 reduces manual intervention, and the efficiency of single-plant cuttings is significantly improved, effectively meeting the needs of large-scale seedling cultivation.

[0044] Among them, the cutting box 1 serves as the basic supporting structure of the entire device, and an opening is provided at the bottom thereof to facilitate cutting operations. A strip groove 2 is provided on the surface of the cutting box 1, and the strip groove 2 provides a channel for the installation and activity of the material rack 4. At the same time, axle seats 3 are symmetrically provided on the inner wall of the cutting box 1, and the axle seats 3 are located on the outside of the strip groove 2, providing a stable support point for the rotation of the material rack 4. The material rack 4 is obliquely arranged inside the cutting box 1, and one end thereof passes through the strip groove 2 to the outside of the cutting box 1, which is convenient for the operator to operate the material rack 4. The central axis is rotatably connected to the inner wall of the shaft seat 3, and a torsion spring is provided between the material rack 4 and the inner wall of the shaft seat 3. The function of the torsion spring is to restore the material rack 4 to its initial state after being rotated by an external force, that is, to maintain the tilt angle of the material rack 4 under normal conditions. A first U-shaped placement groove 5 is provided on the top of the material rack 4, and the cutting branch 6 is placed in the first U-shaped placement groove 5, and the cutting branch 6 is in contact with the inner wall of the cutting box 1 away from the strip groove 2. This design realizes axial limitation and ensures the stability of the cutting branch 6 during the placement process, preventing it from being moved. The lifting seat 7 is connected to the inner wall of the cutting box 1 by vertical sliding, and its position is on the top side of the material rack 4. The bottom of the lifting seat 7 is integrally formed with a tapered portion 8. The initial angle of the tapered portion 8 is consistent with the initial angle of the material rack 4. This design enables the lifting seat 7 to better cooperate with the material rack 4 during the falling process. A second U-shaped placement groove 9 and a third U-shaped placement groove 10 that are adapted to the outer dimensions of the first U-shaped placement groove 5 are respectively provided on the side surface of the lifting seat 7 close to the strip groove 2 and the bottom of the tapered portion 8, and the second U The first U-shaped placement groove 9 is connected to the third U-shaped placement groove 10. This connecting design can ensure the smooth transition and stable placement of the cuttings 6 between different placement grooves. In addition, a column seat 11 is threadedly connected to the inner wall of the upper end of the second U-shaped placement groove 9, and a pressure rod 12 is vertically slidably connected to the inner wall of the column seat 11, and a spring is fixedly connected between the pressure rod 12 and the inner wall of the column seat 11. The cuttings 6 in the vertical state are pressed into the soil through the pressure rod 12. The function of the spring is to provide a certain elastic force for the pressure rod 12 so that the pressure rod 12 can be automatically reset.

[0045] When using the seedling cutting propagation device, first place the cutting branch 6 in the first U-shaped placement groove 5 of the material rack 4, and ensure that one end of the cutting branch 6 is connected to the inner wall of the cutting box 1 away from the strip groove 2, so as to ensure the stability of the initial placement of the cutting branch 6. Then, operate the lifting seat 7 to make it drop vertically. During the dropping process, the lifting seat 7 will synchronously drive the conical part 8 to drop. When the conical part 8 drops to fit with the top of the material rack 4, as the lifting seat 7 continues to drop, the conical part 8 will squeeze the top of the material rack 4. Under the pressure, the central axis of the material rack 4 is connected to the shaft seat 3. Under this pressure, the material rack 4 begins to rotate with the shaft seat 3 as the center, and its state gradually changes from the initial inclined state to the vertical state until it is completely located inside the cutting box 1. During this rotation process, the material rack 4 will synchronously compress the torsion spring, causing the torsion spring to generate elastic potential energy. At the same time, when the material rack 4 is in the inclined state, the first U-shaped placement groove 5 and the third U-shaped placement groove 10 cooperate with each other to position the cutting branch 6 horizontally to prevent it from tilting in the inclined state. When the rack 4 is rotated to a vertical state, the first U-shaped placement groove 5 and the second U-shaped placement groove 9 cooperate with each other to limit the vertical cutting branch 6 to a longitudinal position, thereby ensuring the stability of the cutting branch 6 in the vertical state. When the rack 4 is fully rotated to a vertical state, the end originally located outside the cutting box 1 will fit the surface of the lifting seat 7 and can be slidably connected along the surface; the end originally located inside the cutting box 1 will abut against the inner wall of the cutting box 1 on one side close to the strip groove 2. This design can ensure that the rack 4 in the vertical state, then, as the lifting seat 7 continues to descend, the lifting seat 7 will synchronously descend along the surface of the material rack 4. When the bottom of the lifting seat 7 is aligned with the bottom of the material rack 4 in the vertical state, the pressure rod 12 will descend and drive the cutting branch 6 to be inserted into the soil from the opening at the bottom of the cutting box 1. During this process, the pressure rod 12 will synchronously compress the spring, causing the spring to produce elastic deformation. When the cutting operation is completed, the elastic force of the spring can realize the automatic reset of the pressure rod 12, preparing for the next cutting operation.

[0046] In one embodiment of the present invention, Figure 4 As shown, the bottom of the conical portion 8 is symmetrically threaded with an elastic shaft 81, and is located on the outside of the third U-shaped placement groove 10. The material rack 4 is located at the top of one end inside the cutting box 1 and is symmetrically provided with a guide groove 41, and is located on the outside of the first U-shaped placement groove 5. The position of the elastic shaft 81 corresponds to that of the guide groove 41, and one end of the elastic shaft 81 is located in the guide groove 41 and is slidably connected to the inner wall of the guide groove 41.

[0047] Specifically, in the seedling cutting propagation device, the bottom of the conical part 8 has been carefully designed and is symmetrically threadedly connected to the elastic shaft rod 81, and the two elastic shaft rods 81 are cleverly located on the outside of the third U-shaped placement groove 10. At the same time, the material rack 4 is located at the top of one end inside the cutting box 1, and a guide groove 41 is also symmetrically opened. The position of the guide groove 41 has also been considered and is located on the outside of the first U-shaped placement groove 5. After precise layout design, the position of the elastic shaft rod 81 and the guide groove 41 correspond exactly. In actual operation, one end of the elastic shaft rod 81 will be accurately placed in the guide groove 41 and can be smoothly slid and connected along the inner wall of the guide groove 41. Through the cooperation of the elastic shaft rod 81 and the guide groove 41, the flipping angle of the material rack 4 can be effectively limited, and at the same time, the impact force when the lifting seat 7 descends can be buffered, and the use effect is good.

[0048] In one embodiment of the present invention, Figure 3 As shown, an opening is provided at one end of the guide groove 41 away from the shaft seat 3 and is in the same plane as the end surface of the material rack 4 , and the depth of the guide groove 41 gradually decreases along the shaft seat 3 toward the opening.

[0049] Specifically, an opening is provided at one end of the guide groove 41 away from the shaft seat 3, and the opening is in the same plane as the end face of the material rack 4. Such a design greatly facilitates the subsequent removal of the elastic shaft rod 81 from the inside of the guide groove 41. At the same time, the depth of the guide groove 41 gradually decreases along the shaft seat 3 toward the opening. This gradual depth design is not arbitrary. During the sliding process of the elastic shaft rod 81, as the depth gradually changes, it can provide it with more precise guidance and smoother transition. When the elastic shaft rod 81 approaches the shaft seat 3, the deeper guide groove 41 can provide stronger support and constraint to ensure its stable operation. As it slides toward the opening, the depth gradually becomes shallower and gradually decreases to form an inclined guide surface, so that the elastic shaft rod 81 slides smoothly when the material rack 4 flips, avoiding jamming or jumping caused by sudden changes in depth, thereby ensuring the stability and reliability of the operation of the entire device.

[0050] In one embodiment of the present invention, Figure 4 As shown, the upper end surface and the lower end surface of the lifting seat 7 close to the strip groove 2 are symmetrically slidably connected with balls 71, and are located outside the second U-shaped placement groove 9. An arc-shaped buffer portion is provided at the connection between the second U-shaped placement groove 9 and the third U-shaped placement groove 10.

[0051] Specifically, the ball bearings 71 reduce the friction between the lifting seat 7 and the surface of the material rack 4 when the lifting seat 7 slides, thereby improving the sliding smoothness, and the arc-shaped buffer portion prevents the cutting branches 6 from being stuck or damaged at the turning point.

[0052] In one embodiment of the present invention, Figure 2As shown, the first U-shaped placement groove 5 and the third U-shaped placement groove 10 cooperate to form a first limiting groove for horizontally positioning the cutting branch 6, and the first U-shaped placement groove 5 and the second U-shaped placement groove 9 cooperate to form a second limiting groove for longitudinally transporting the cutting branch 6. When the material rack 4 is flipped to a vertical state, the first U-shaped placement groove 5, the second U-shaped placement groove 9, the column seat 11 and the pressure rod 12 are all on the same axial line.

[0053] Specifically, the first U-shaped placement groove 5 and the third U-shaped placement groove 10 cooperate to form a first limiting groove for horizontal positioning of the cutting branch 6. The size and shape of the first limiting groove have been precisely calculated and can fit closely to the horizontal contour of the cutting branch 6, effectively limiting its movement in the horizontal direction, ensuring the precise positioning of the cutting branch 6 in the horizontal position, and providing a stable reference for subsequent cutting operations. At the same time, the first U-shaped placement groove 5 and the second U-shaped placement groove 9 cooperate with each other to form a second limiting groove for longitudinally conveying the cutting branch 6. The design of the second limiting groove fully considers the smoothness of the cutting branch 6 in the longitudinal movement process. The U-shaped rack 4 has good stability and its inner wall is smooth, which reduces friction resistance, so that the cutting branches 6 can be transported smoothly and quickly in the longitudinal direction, thereby improving the cutting efficiency. It is particularly worth mentioning that when the material rack 4 is flipped to a vertical state, the first U-shaped placement groove 5, the second U-shaped placement groove 9, the column base 11 and the pressure rod 12 are all on the same axis. This ingenious design ensures that during the vertical cutting process, each component can apply uniform and stable force to the cutting branches 6, so that the cutting branches 6 can be vertically inserted into the soil, avoiding problems such as uneven force, bending or breaking of the cutting branches 6 due to component position deviation, thereby greatly improving the survival rate and quality of the cuttings.

[0054] In one embodiment of the present invention, Figure 5 As shown, a power mechanism 13 is fixedly connected to the top of the cutting box 1, and the power mechanism 13 includes a mounting seat 131, a first power push rod 132 and a second power push rod 133. The mounting seat 131 is fixedly connected to the top of the cutting box 1, and the first power push rod 132 and the second power push rod 133 are fixedly connected to the mounting seat 131, respectively, and correspond to the positions of the pressure rod 12 and the lifting seat 7. The output end of the first power push rod 132 passes through the interior of the cutting box 1 and is fixedly connected to a sleeve 134. The sleeve 134 is sleeved on the outside of the pressure rod 12 and abutted and fixed with the top of the pressure rod 12. The output end of the second power push rod 133 passes through the interior of the cutting box 1 and is fixedly connected to the top of the lifting seat 7;

[0055] The first power push rod 132 and the second power push rod 133 can be pneumatic push rods, hydraulic push rods or electric push rods.

[0056] Specifically, the structural design of the seedling cutting propagation device fully considers the needs of automated operation, and a power mechanism 13 is carefully arranged on the top of the cutting box 1 to achieve accurate and efficient power output and control. The power mechanism 13 is mainly composed of a mounting seat 131, a first power push rod 132 and a second power push rod 133. The mounting seat 131 is the basic supporting component of the power mechanism 13 and is firmly fixedly connected to the top of the cutting box 1, providing a stable mounting platform for the first power push rod 132 and the second power push rod 133. The first power push rod 132 and the second power push rod 133 are accurately fixedly connected to the mounting seat 131 respectively, and their positions correspond to the pressure rod 12 and the lifting seat 7, ensuring that power can be accurately transmitted to the corresponding components. The output end of the first power push rod 132 cleverly penetrates into the interior of the cutting box 1 and is fixedly connected to a sleeve 134. The sleeve 134 is sleeved on the outside of the pressure rod 12 and is tightly abutted and fixed to the top of the pressure rod 12. This design makes The first power push rod 132 can stably transmit power to the pressure rod 12 through the sleeve 134, thereby realizing precise driving of the pressure rod 12, and then completing operations such as pressing the cutting branches 6. The output end of the second power push rod 133 also passes through the interior of the cutting box 1 and is directly fixedly connected to the top of the lifting seat 7. Through the telescopic movement of the second power push rod 133, the lifting height and position of the lifting seat 7 can be accurately controlled to meet the needs of different cutting operations. In the selection of power push rods, the first power push rod 132 and the second power push rod 133 have a variety of options, and pneumatic push rods, hydraulic push rods or electric push rods can be selected. The pneumatic push rod has the advantages of fast response speed and smooth movement; the hydraulic push rod can provide a larger thrust and is suitable for heavy-load occasions; the electric push rod has high control accuracy and is easy to install. It can be flexibly selected according to the actual usage scenario and performance requirements to ensure that the power mechanism 13 can operate stably and reliably, providing strong power support for seedling cutting propagation operations.

[0057] In one embodiment of the present invention, Figure 6 As shown, it also includes a material guide seat 100, the inclination angle of the material guide seat 100 is consistent with that of the material rack 4, and one end thereof is aligned with the end of the material rack 4 located outside the cutting box 1, and a fourth U-shaped placement groove 200 is provided on the top of the material guide seat 100, and is on the same axial line as the first U-shaped placement groove 5, and the inner wall of the end of the material guide seat 100 close to the material rack 4 is vertically slidably connected with an L-shaped stopper 300, and a return spring is fixedly connected to the inner wall of the material guide seat 100, the vertical section of the L-shaped stopper 300 passes through the interior of the fourth U-shaped placement groove 200, and the horizontal section of the L-shaped stopper 300 is fixed to the bottom of the material rack 4.

[0058] It should be noted that the return spring described in this embodiment is not shown in the figure.

[0059] It should also be noted that the material rack 4 and the material guide seat 100 described in this embodiment are in a non-contact state, and there is a set distance between them.

[0060] Specifically, the material guide seat 100 is a key and ingenious component in the equipment. The inclination angle of the material guide seat 100 has been carefully designed to be consistent with the material rack 4. This design is not arbitrary, but is to ensure that the cutting branches 6 can maintain a stable and smooth movement state when transitioning from the material guide seat 100 to the material rack 4, to avoid the branches from getting stuck or slipping due to angle differences. One end of the material guide seat 100 is precisely aligned with the end of the material rack 4 located outside the cutting box 1, building a conveying channel for the cutting branches 6. At the top of the material guide seat 100, a fourth U-shaped placement groove 200 is opened, and it is on the same axis as the first U-shaped placement groove 5, ensuring that the cutting branches 6 can always move along the predetermined straight line during the conveying process, laying the foundation for the subsequent precise positioning and cutting operation in the first U-shaped placement groove 5. In addition, the material guide seat 100 The L-shaped stopper 300 is cleverly provided on the inner wall near one end of the material rack 4, and a return spring is fixedly connected between the L-shaped stopper 300 and the inner wall of the material guide seat 100, which makes the L-shaped stopper 300 have a certain elastic activity space, and its vertical section passes through the fourth U-shaped placement groove 200, which can play a certain blocking role for the cutting branch 6 entering the material guide seat 100, and the horizontal section is fixed to the bottom of the material rack 4, further enhancing the stability of the structure. When the material rack 4 is reset and the horizontal section of the L-shaped stopper 300 is pressed down, the L-shaped stopper 300 is subjected to the force and drops as a whole, and the return spring is compressed. When the material rack 4 is aligned with the material guide seat 100, the cutting branch 6 inside the material guide seat 100 loses the obstruction of the vertical part of the L-shaped stopper 300 and automatically enters the first U-shaped placement groove 5 under the action of gravity. The whole process is automatic and efficient, and does not require excessive human intervention.

[0061] In one embodiment of the present invention, Figure 6 As shown, the material guide seat 100 is integrally formed with a triangular portion on one end surface away from the material rack 4, and a triangular material guide groove is opened on the top of the triangular portion, which is connected to the inside of the fourth U-shaped placement groove 200.

[0062] It should be noted that the triangular portion and the triangular material guide trough described in this embodiment are not shown in the figure.

[0063] It should also be noted that the material guide seat 100 described in this embodiment is fixedly connected to the mobile vehicle body and is located on the left side of the cutting box 1.

[0064] Specifically, through the cooperation between the triangular portion and the triangular material guide groove, the cutting branches 6 can be effectively guided to automatically slide into the fourth U-shaped placement groove 200, thereby improving the convenience of loading.

[0065] In summary, the seedling cutting propagation device of the embodiment of the present invention has a reasonable structure. By integrating core components such as the material rack 4 and the lifting seat 7 into the cutting box 1, the large swing arm is eliminated, and the space occupancy is greatly reduced. It is convenient for modular integration with equipment such as watering and fertilizing, and the space utilization rate of the mobile vehicle body is improved. The various components are detachably connected to adapt to different vehicle bodies and branch sizes, reducing the cost of modification and maintenance; multiple groups of U-shaped placement grooves are used to achieve stable positioning of branches, and the flipping of the material rack 4 and the pushing of the pressure rod 12 are coordinated to ensure the verticality of the cuttings, reduce soil extrusion and branch deviation, and the cutting depth error is small, which improves the survival rate. The automatic feeding design of the power mechanism 13 and the material guide seat 100 reduces manual intervention, and the efficiency of single-plant cuttings is significantly improved, which efficiently meets the needs of large-scale seedling cultivation.
