Description

Technical Field

[0001] This invention relates to the technical field of cutting propagation equipment, and more particularly to a rapid cutting propagation device for seedlings in saline-alkali land. Background Technology

[0002] In the field of saline-alkali land ecological restoration and seedling propagation, cutting propagation technology has become the core process because it can efficiently preserve the stress resistance traits of the mother plant (such as salt and alkali tolerance and drought resistance).

[0003] However, existing cutting propagation equipment exhibits dual technical deficiencies in extreme saline-alkali soil conditions: a lack of end-to-end coordination and insufficient environmental adaptability. This results in large-scale seedling production efficiency and seedling survival rates consistently falling below industry benchmarks. The specific technical contradictions are as follows:

[0004] 1. A break in the process chain leads to a precipitous drop in efficiency.

[0005] Cuttings in saline-alkali land require a coordinated operation of the entire process, including disinfection, straightening, cutting, inserting, pressing soil, and watering. However, traditional equipment only supports a single cutting operation, which requires the purchase of corresponding equipment, resulting in increased initial investment. Due to the long material transfer time between equipment, work efficiency is low, and the seedling survival rate is significantly reduced due to process delays.

[0006] 2. Spatial and transition constraints limit large-scale application.

[0007] Split-type equipment occupies a large space, while saline-alkali land is fragmented, which means that it needs to be moved frequently during use. Due to terrain limitations, the relocation of split-type equipment is extremely inconvenient, resulting in long relocation times and significantly increased labor costs. Summary of the Invention

[0008] The present invention aims to at least partially solve one of the technical problems in the related art.

[0009] Therefore, the purpose of this invention is to propose a rapid cutting propagation device for seedlings in saline-alkali land. This invention, through innovative integrated design, deeply integrates core functions such as disinfection, straightening, cutting, cutting, soil pressing, and watering, constructing a complete process operation system for cutting propagation of seedlings in saline-alkali land. This significantly improves the efficiency of cutting propagation in saline-alkali land. Through rapid process connection and precise control of parameters in each link, it effectively improves the survival rate of seedlings. Its compact vehicle-mounted layout and convenient modular characteristics significantly reduce the labor cost and equipment relocation difficulty for large-scale seedling cultivation in saline-alkali land, demonstrating excellent practicality and reliability.

[0047] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0048] The following description, in conjunction with the accompanying drawings, describes a rapid cutting propagation device for seedlings in saline-alkali land according to an embodiment of the present invention.

[0049] like Figures 1-8 As shown in the figure, a rapid cutting propagation device for seedlings in saline-alkali land according to an embodiment of the present invention includes a cutting device 2 mounted on a mobile vehicle 1. The cutting device 2 includes:

[0050] Seat 3: Set on the mobile vehicle body 1, its surface is provided with a scion groove 31 and a high-pressure water tank 32 in sequence along the vertical direction, and its interior is provided with a pressing mechanism 33, which is located on one side of the high-pressure water tank 32.

[0051] The cutting mechanism 4 includes a side V-shaped feeding rack 41, a conical guide hopper 42, a wheel straightener 43, a double-cutting mechanism 44, and a guide wheel mechanism 45 arranged sequentially on the surface of the base 3 in the vertical direction. The guide wheel mechanism 45 is located on the outer side of the end of the pressing mechanism 33 that extends out of the base 3. The wheel straightener 43, the double-cutting mechanism 44, and the guide wheel mechanism 45 are all driven by the driving mechanism 5 arranged on the surface of the base 3.

[0052] The drive mechanism 5 is equipped with a pressure plate 6, which is located on one side of the bottom of the guide wheel mechanism 45. The pressure plate 6 is connected to the inside of the high-pressure water tank 32 through a water supply hose.

[0053] It should be noted that the bottom of the mobile vehicle body 1 described in this embodiment is provided with a tracked walking mechanism or a wheeled walking mechanism (not shown in the figure). The built-in motor of the tracked walking mechanism or the wheeled walking mechanism is electrically connected to the controller (not shown in the figure) provided on the mobile vehicle body 1. In order to facilitate coordinated control, the double-cutting mechanism 44, the drive mechanism 5 and the high-pressure water tank 32 are all electrically connected to the controller (not shown in the figure) on the mobile vehicle body 1.

[0054] It should be noted that the high-pressure water tank 32 described in this embodiment is equipped with a pressure sensor (not shown in the figure) and a liquid level sensor (not shown in the figure) on its inner wall. The seat 3 is equipped with a pressurizing mechanism (not shown in the figure). The pressure sensor, liquid level sensor and pressurizing mechanism are all electrically connected to the controller on the mobile vehicle 1. The pressurizing mechanism is used to automatically pressurize the high-pressure water tank 32 when the pressure sensor detects that the internal pressure of the high-pressure water tank 32 is lower than the set pressure value, so as to maintain it at the set pressure and ensure stable water output. The liquid level sensor is used to detect the liquid level data inside the high-pressure water tank 32. When the liquid level is lower than the set liquid level, it issues an alarm prompt through the controller.

[0055] It should be noted that a filtration device (not shown in the figure) is provided at the inlet of the high-pressure water tank 32 described in this embodiment. The filtration device includes a filter element and a housing, and the filter element is an activated carbon filter element.

[0056] It should be noted that the scion insertion groove 31 described in this embodiment is filled with disinfectant.

[0057] It should be noted that the seat 3 described in this embodiment is a detachable structure. The seat 3 is fixedly connected to the mobile vehicle 1 by bolts. The mobile vehicle 1 is equipped with a power supply, which is electrically connected to the controller.

[0058] Specifically, this invention, through innovative integrated design, deeply integrates core functions such as disinfection, straightening, cutting, cutting, soil pressing, and watering, constructing a complete process operation system for cutting propagation of seedlings in saline-alkali land. This significantly improves the efficiency of cutting propagation in saline-alkali land. By precisely controlling parameters at each stage (such as straightening force, cutting angle, soil pressing depth, and watering volume), it effectively improves the survival rate of seedlings. Its compact vehicle-mounted layout and convenient modular characteristics significantly reduce the labor costs and equipment relocation difficulties of large-scale seedling cultivation in saline-alkali land, demonstrating excellent practicality and reliability.

[0059] Taking long cuttings of Amorpha fruticosa as an example, this device enables the entire process of cutting propagation:

[0060] 1. Place the long cuttings in the cutting groove 31 and disinfect the surface with the disinfectant solution in the groove;

[0061] 2. Drive the mobile vehicle 1 to the target insertion area;

[0062] 3. Place the long scion in the side V-shaped feeding rack 41, then pull down the long scion so that its bottom enters the conical guide hopper 42, and then passes out from the bottom of the conical guide hopper 42 and enters the annular groove of the wheel straightener 43;

[0063] 4. Start drive mechanism 5. Drive mechanism 5 controls the operation of each component according to the following timing sequence:

[0064] The wheel-type straightener 43 and the guide wheel mechanism 45 are activated simultaneously to straighten long scions and transport short scions.

[0065] Activate the pressing mechanism 33 to press the short cuttings on the guide wheel mechanism 45 into the soil to achieve cutting propagation;

[0066] The double-cutting mechanism 44 and the pressing plate 6 are activated simultaneously to achieve the cutting of long cuttings and compaction and water injection;

[0067] The wheel straightener 43 applies axial tension to the long cuttings through the annular groove to eliminate bending stress. Then, the double-cutting mechanism 44 completes the double-end cutting of the short cuttings, forming a flat top and a slanted bottom. The guide wheel mechanism 45 transports the cut short cuttings to the underside of the pressing mechanism 33. The pressing mechanism 33 presses the short cuttings into the soil. Finally, the pressing plate 6 completes the soil compaction and watering operations.

[0068] In one embodiment of the present invention, such as Figure 1 and Figure 4 As shown, the pressing mechanism 33 includes a turntable 331 rotatably connected to the inner wall of the base 3. A pressing rod 332 is threadedly connected to the outer surface of the turntable 331. One end of the pressing rod 332 extends out of the base 3 and is located inside the guide wheel mechanism 45. One end of the central shaft of the turntable 331 is fixedly connected to a one-way transmission device 333. The other end of the one-way transmission device 333 is fixedly connected to a drive gear 334. The drive gear 334 meshes with one end of the drive mechanism 5 that extends into the interior of the base 3.

[0069] It should be noted that the surface of the seat 3 described in this embodiment is provided with a strip groove, and one end of the pressure rod 332 passes through the strip groove and extends out of the seat 3.

[0070] Specifically, the structure and connection relationship of the pressing mechanism 33 are further explained. In use, the lower tooth seat 56 in the drive mechanism 5 descends and simultaneously drives the second tooth part 58 to descend. The descent of the second tooth part 58 simultaneously drives the drive gear 334 to rotate. The rotation of the drive gear 334 simultaneously drives the turntable 331 to rotate through the one-way transmission 333. The rotation of the turntable 331 simultaneously drives the pressing rod 332 to rotate. During the rotation of the pressing rod 332, the short cuttings on the guide wheel mechanism 45 are pressed down and pressed into the soil to realize the cutting.

[0071] In one embodiment of the present invention, such as Figure 2 As shown, the side V-shaped feeding rack 41 includes a fixed frame 411 fixedly connected to the surface of the base 3. A V-shaped groove 412 is opened on the side surface of the fixed frame 411 facing the tassel groove 31. An elastic limiting piece 413 is welded and fixed to the inner wall of the V-shaped groove 412.

[0072] At least three sets of side V-shaped feeding racks 41 are provided, and the center of the V-shaped groove 412 on the three sets of side V-shaped feeding racks 41 and the center of the conical guide hopper 42 are all on the same axis.

[0073] It should be noted that the fixing frame 411 described in this embodiment is provided with a weight reduction groove.

[0074] Specifically, the structure and connection relationship of the side V-shaped feeding rack 41 are further explained. The fixing frame 411 is designed to be easily fixed on the base 3. The V-shaped groove 412 is designed to serve as a guide, making it easy to put the long scion into the innermost part of the V-shaped groove 412. The elastic limiting piece 413 is designed to limit the long scion placed into the innermost part of the V-shaped groove 412, preventing it from deviating and ensuring that the axis of the long scion and the center line of the annular groove always maintain a high degree of coaxiality. By cooperating with the conical guide hopper 42, the stability and the accuracy of insertion into the annular groove are significantly improved, resulting in good performance.

[0075] In one embodiment of the present invention, such as Figure 1 and Figure 4 As shown, the wheel straightener 43 includes three sets of wheel units 431 arranged in sequence along the vertical direction on the surface of the seat 3. Each wheel unit 431 includes a first drive wheel 432 and a second drive wheel 433. The first drive wheel 432 is symmetrically arranged in opposite directions along the X-axis on the surface of the seat 3, and the second drive wheel 433 is symmetrically arranged in opposite directions along the Y-axis on the surface of the seat 3 and is located on one side of the bottom of the first drive wheel 432. One end of the central shaft of each of the two sets of first drive wheels 432 penetrates into the interior of the seat 3 and is fixedly connected to an upper transmission gear 434. The two sets of upper transmission gears 434 mesh with each other, and one set of upper transmission gears 434 meshes with one end of the drive mechanism 5 that penetrates into the interior of the seat 3.

[0076] The guide wheel mechanism 45 includes a first guide wheel 451 and a second guide wheel 452. The first guide wheel 451 is symmetrically and oppositely arranged on the surface of the seat body 3 along the X-axis and is located on one side of the bottom of the double-cut mechanism 44. The second guide wheel 452 is symmetrically and oppositely arranged on the surface of the seat body 3 along the X-axis and is located on one side of the bottom of the first guide wheel 451. One end of each set of first guide wheels 451 penetrates into the interior of the seat body 3 and is fixedly connected to an internal drive gear 453. One set of internal drive gears 453 is meshed with the end of the drive mechanism 5 that penetrates into the interior of the seat body 3. The end of the pressure rod 332 that penetrates out of the exterior of the seat body 3 is located between the two sets of second guide wheels 452.

[0077] It should be noted that the first drive wheel 432, the second drive wheel 433, the first guide wheel 451 and the second guide wheel 452 described in this embodiment are all elastic rollers. The outer circumferential surface of the elastic roller is provided with an annular groove that matches the scion, and the inner wall of the annular groove is provided with anti-slip texture.

[0078] It should also be noted that the center lines of the V-shaped groove 412, the conical guide hopper 42, and the annular groove described in this embodiment are all on the same axis.

[0079] It should also be noted that a one-way transmission device 333 is also provided between one end of the central shaft of the first drive wheel 432 and the upper transmission gear 434, and between one end of the central shaft of the first guide wheel 451 and the inner drive gear 453. The one-way transmission device 333 at this position is not shown in the figure.

[0080] Specifically, the structure and connection relationship of the wheel straightener 43 and the guide wheel mechanism 45 are further explained. In use, the upper tooth seat 55 and the lower tooth seat 56 on the drive mechanism 5 descend synchronously, driving the first tooth part 57 to descend. The descent of the first tooth part 57 synchronously drives the upper transmission gear 434 and the inner drive gear 453 to rotate. The rotation of the upper transmission gear 434 synchronously drives the first drive wheel 432 to rotate. Through coordinated operation with the second drive wheel 433, the straightening and conveying operation of long scions is realized. The rotation of the inner drive gear 453 synchronously drives the first guide wheel 451 to rotate. Through coordinated operation with the second guide wheel 452, the conveying operation of short scions is realized.

[0081] In one embodiment of the present invention, such as Figures 6-7 As shown, the double-cutting mechanism 44 includes a box body 441, a conical guide cup 442, an upper guide cylinder 443, a lower guide cylinder 444, a shift seat 445, a return spring 446, a guide groove 447, a flat cutter 448, a bevel cutter 449, and a fan 4410.

[0082] The box body 441 is fixedly connected to the surface of the base 3 and is located on one side of the bottom of the lowest set of second drive wheels 433. The conical guide cup 442 is fixedly connected to the top of the box body 441. The upper guide cylinder 443 and the lower guide cylinder 444 are respectively fixedly connected to the inner wall of the upper end of the box body 441 and the inner wall of the lower end of the box body 441, and are on the same axis as the conical guide cup 442. The shift seat 445 is horizontally slidably connected to the surface of the box body 441, and a return spring 446 is fixedly connected between the shift seat 445 and the surface of the box body 441. The guide groove 447 is opened on the surface of the shift seat 445. One end of the drive mechanism 5 is located at... Inside the guide groove 447, and slidably connected to the inner wall of the guide groove 447, the flat-edged cutter 448 and the beveled cutter 449 are respectively fixedly connected to the upper and lower surfaces of the shift seat 445. One end of the flat-edged cutter 448 and the beveled cutter 449 respectively penetrates into the interior of the box 441 and abuts against the inner walls of the first slot 4431 and the second slot 4432 on the upper guide cylinder 443. The fan 4410 is set on the surface of the box 441, and the output end of the fan 4410 penetrates into the interior of the box 441 and corresponds to the spatial position between the upper guide cylinder 443 and the lower guide cylinder 444.

[0083] It should be noted that the mounting angle of the bevel cutter 449 described in this embodiment is set to 45°.

[0084] It should also be noted that the surface of the box 441 described in this embodiment is provided with slots to facilitate the penetration of the flat cutter 448 and the oblique cutter 449 into the interior of the box 441.

[0085] It should also be noted that the box 441 described in this embodiment is a single-opening design. The opening 4441 of the box 441 is located on the side surface of the box 441 away from the transfer seat 445. The opening 4441 is designed to facilitate the discharge of the cut branches. To further facilitate the discharge of branches, a guide part (not shown in the figure) is also provided on the inner wall of the box 441.

[0086] Specifically, the structure and connection relationship of the double-cutting mechanism 44 will be further explained. When in use, when the convex shaft 510 in the drive mechanism 5 moves along the inner wall of the inclined section in the guide groove 447, it simultaneously squeezes the shift seat 445 to move towards the box body 441 and compresses the return spring 446. The movement of the shift seat 445 simultaneously drives the flat cutter 448 and the oblique cutter 449 into the box body 441 and cuts the long tassels at the positions of the first slot 4431 and the second slot 4432. The cut short tassels enter the guide wheel mechanism 45 and are conveyed by the guide wheel mechanism 45. The cut residue will be discharged from the outside of the box body 441 by the blower 4410.

[0087] In one embodiment of the present invention, such as Figures 6-7 As shown, the guide groove 447 includes a vertical section and an inclined section, which are integrally formed and internally connected.

[0088] An opening 4441 is provided at the bottom of the upper guide cylinder 443 and the top of the lower guide cylinder 444 respectively. The opening 4441 is located on the side surface of the upper guide cylinder 443 and the lower guide cylinder 444 away from the fan 4410.

[0089] Specifically, the vertical section design facilitates the operation of the drive mechanism 5 driving the wheel straightener 43, the guide wheel mechanism 45, and the pressing mechanism 33, but does not drive the double-cutting mechanism 44. The oblique section design facilitates the operation of the drive mechanism 5 driving the double-cutting mechanism 44, but does not drive the wheel straightener 43, the guide wheel mechanism 45, and the pressing mechanism 33.

[0090] The opening 4441 is designed to facilitate the discharge of the remaining material after the long scion is cut, which is then easily discharged from the upper guide cylinder 443 and the lower guide cylinder 444 by the blower 4410, resulting in good performance.

[0091] In one embodiment of the present invention, such as Figures 3-5 As shown, the drive mechanism 5 includes a mounting base 51, a slide 54, an upper gear seat 55, a lower gear seat 56, a second tooth portion 58, and a convex shaft 510. The mounting base 51 is fixedly connected to the surface of the base body 3. A guide shaft 52 and a reciprocating lead screw 53 are respectively provided at the bottom of the mounting base 51. A drive motor is fixedly connected to the inner wall of the mounting base 51 and connected to one end of the reciprocating lead screw 53. The slide 54 is threadedly connected to the surface of the reciprocating lead screw 53 and sleeved on the outside of the guide shaft 52. The upper gear seat 55 and the lower gear seat 56 are vertically slidably connected to the inner wall of the base body 3. One end of the upper gear seat 55 and the lower gear seat 56 respectively extends through the outside of the base body 3 and is fixedly connected to the surface of the slide 54. The surfaces of the upper gear seat 55 and the lower gear seat 56 are respectively provided with a first tooth portion 57. The first tooth portion 57 of the upper gear seat 55 is located on one side of the upper transmission gear 434 and is meshed with the upper transmission gear 434. The first tooth portion 57 of the lower gear seat 56 is located on one side of the inner drive gear 453 and is meshed with the inner drive gear 453. The second tooth portion 58 is integrally formed on the surface of the lower gear seat 56 and is located on one side of the drive gear 334. The second tooth portion 58 is meshed with the drive gear 334. The cam shaft 510 is fixedly connected to the positioning seat 59 on the surface of the slide 54. One end of the cam shaft 510 is located in the guide groove 447 and is slidably connected to the inner wall of the guide groove 447.

[0092] It should be noted that, in this embodiment, the lower end of the carriage 54 is fitted onto the limiting guide rod 100 on the surface of the moving vehicle body 1.

[0093] It should be noted that the drive motor described in this embodiment is electrically connected to the controller (not shown in the figure) on the mobile vehicle body 1.

[0094] Specifically, the structure and connection relationship of the drive mechanism 5 are further explained. The drive mechanism 5 adopts a single power design and can drive the wheel straightener 43, the double-cutting mechanism 44, the guide wheel mechanism 45 and the pressure plate 6 to perform the cutting operation in coordination.

[0095] In use, the drive motor receives the command and operates, driving the reciprocating screw 53 to rotate synchronously. Under the guidance of the guide shaft 52, the slide 54 reciprocates and moves up and down along the outer surface of the reciprocating screw 53. When the slide 54 descends, it drives the upper gear seat 55, the lower gear seat 56 and the cam shaft 510 to move down synchronously. In the initial stage, the cam shaft 510 is located in the vertical section of the guide groove 447 in the double-cutting mechanism 44. When the upper gear seat 55 descends, the first tooth portion 57 on its surface drives the internal drive gear 453 of the guide wheel mechanism 45 to rotate. During the descent of the lower gear seat 56, the first tooth portion 57 on its surface also acts on the internal drive gear 453. At the same time, the second tooth portion 58 drives the drive gear 334 to rotate after a set delay time. As the slide 54 continues to descend, the cam shaft 510 moves from the vertical section of the guide groove 447 to the inclined section, pushing the shift seat 445 of the double-cutting mechanism 44 to move to one side 441 of the box, realizing the linkage of each mechanism according to the preset program.

[0096] In one embodiment of the present invention, such as Figure 3 and Figure 8 As shown, water injection pipes 61 are symmetrically arranged at the bottom of the pressure plate 6 and are connected to the inside of the pressure plate 6. A U-shaped groove 62 is opened on the surface of the pressure plate 6 and corresponds to the position of the pressure rod 332.

[0097] The bottom of the pressure plate 6 is provided with column grooves corresponding to the position of the water injection pipe 61. Water seats 601 are fixedly connected to the inner wall of the column grooves. The water seats 601 are connected to the inside of the pressure plate 6. The water injection pipe 61 is located in the column groove and is fixedly connected to the inner wall of the column groove with a compression spring 602. One end of the water injection pipe 61 passes through the inside of the water inlet seat 601. Water inlet holes 603 are provided on the surface of the end of the water injection pipe 61 that passes through the inside of the water inlet seat 601 and are connected to the inner wall of the water seat 601. The other end of the water injection pipe 61 passes through the outside of the column groove and is provided with drain holes 604 evenly.

[0098] It should be noted that, in order to ensure that the two sets of water inlets 603 are precisely connected and interconnected, the depth of the column groove needs to be limited. To improve the sealing performance, a sealing ring is also provided at the connection between the water injection pipe 61 and the column groove. The sealing ring is located on the outside of the water inlet 603.

[0099] It should also be noted that the drain hole has a built-in 80-mesh stainless steel filter to intercept soil particles and prevent clogging.

[0100] Specifically, the structure and connection of the water injection pipe 61 are further explained. The water injection pipe 61 is designed to facilitate the injection of water into the soil around the short cuttings, thereby improving the survival rate of the short cuttings. The water injection pipe 61 adopts a pressure-sensitive adaptive water injection structure, which is pressed down synchronously with the pressure plate 6. Its bottom is gradually inserted into the soil around the short cuttings, and it works with the pressure plate 6 to complete the compaction operation. During the downward movement, the compression spring 602 is compressed and contracts. When the water inlet 603 on the outer wall of the water injection pipe 61 is aligned with the water inlet 603 on the inner wall of the water seat 601 and connected... When the system is activated, the liquid in the high-pressure water tank 32 is automatically injected into the water injection pipe 61 under pressure, and then evenly permeates into the soil through the drain hole 604. When the pressure plate 6 is lifted, the water injection pipe 61 is reset under the action of the compression spring 602, and the water inlet 603 is quickly misaligned to achieve instantaneous interception. At the same time, the drain hole 604 has an 80-mesh stainless steel filter screen built in it to intercept soil particles and prevent blockage. The overall design achieves precise control and anti-leakage function for cutting irrigation in saline-alkali land through a three-level collaborative mechanism of mechanical linkage, pressure sensing and adaptive sealing.

[0101] The U-shaped groove 62 on the pressure plate 6 provides operating space for the pressure rod 332, preventing it from interfering with the stroke of the pressure rod 332, resulting in good performance.

[0102] In summary, the rapid cutting propagation equipment for saline-alkali land seedlings according to embodiments of the present invention, through innovative integrated design, deeply integrates core functions such as disinfection, straightening, cutting, cutting, soil pressing, and watering, constructing a complete process operation system for cutting propagation of saline-alkali land seedlings. This significantly improves the efficiency of cutting propagation in saline-alkali land. Through rapid process connection and precise control of parameters at each stage, it effectively improves the survival rate of seedlings. Its compact vehicle-mounted layout and convenient modular characteristics significantly reduce the labor costs and equipment relocation difficulties for large-scale seedling cultivation in saline-alkali land, demonstrating excellent practicality and reliability.
