Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and in particular to a rapid cutting equipment for seedlings in saline-alkali land for nursery stock breeding. Background Art

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

[0003] However, the existing cutting equipment exposes double technical defects of the lack of full-process coordination and insufficient environmental adaptability under the extreme working conditions of saline-alkali land, resulting in the long-term low efficiency of large-scale seedling raising and the survival rate of seedlings being lower than the industry benchmark value. The specific technical contradictions are as follows:

[0004] 1. The breakage of the process chain leads to a cliff-like decline in efficiency

[0005] Cutting in saline-alkali land requires the full-process coordinated operation of disinfection → straightening → cutting → inserting → soil pressing → watering. However, traditional equipment only supports single cutting operations, which requires the purchase of corresponding equipment separately, resulting in an increase in initial investment. Since the material transfer time between equipment accounts for a long proportion of the time, the working efficiency is low, and the survival rate of seedlings is also significantly reduced due to process delays;

[0006] 2. Space and transfer constraints restrict large-scale application

[0007] The split-type equipment occupies a large space, and the saline-alkali land plots are fragmented, resulting in frequent transfers during its use. Due to terrain restrictions, the transfer of split-type equipment is extremely inconvenient, resulting in a long transfer time and a significant increase in the corresponding labor cost. Summary of the Invention

[0008] The present invention aims to solve at least one of the technical problems in the related technologies to some extent.

[0009] To this end, the object of the present invention is to provide a rapid cutting equipment for seedlings in saline-alkali land for nursery stock breeding. Through innovative integrated design, the present invention deeply integrates core functions such as disinfection, straightening, cutting, inserting, soil pressing and watering, constructs a full-process operation system for cutting seedlings in saline-alkali land, significantly improves the cutting efficiency of seedlings in saline-alkali land, effectively improves the survival rate of seedlings through rapid process connection and precise control of each link parameter, and its compact vehicle-mounted layout and convenient module characteristics significantly reduce the labor cost and equipment transfer difficulty of large-scale seedling raising in saline-alkali land, and the practicability and reliability are excellent.

[0047] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where 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 by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications and equivalents falling within the spirit and scope of the appended claims

[0048] Next, a rapid cutting device for seedlings in saline-alkali land for breeding seedlings of the present invention will be described with reference to the accompanying drawings

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

[0050] Seat body 3: provided on the mobile vehicle body 1, on the surface of which there are successively arranged a cutting spike groove 31 and a high-pressure water tank 32 in the vertical direction, and a branch pressing mechanism 33 is arranged inside it and is located on one side of the high-pressure water tank 32

[0051] Cutting mechanism 4: including a side V-shaped feeding rack 41, a conical feeding hopper 42, a wheel-type straightener 43, a double-cutting mechanism 44 and a guide wheel mechanism 45 successively arranged on the surface of the seat body 3 in the vertical direction. Among them, the guide wheel mechanism 45 is located outside one end of the branch pressing mechanism 33 passing through the outside of the seat body 3. The wheel-type straightener 43, the double-cutting mechanism 44 and the guide wheel mechanism 45 are all driven by a driving mechanism 5 provided on the surface of the seat body 3

[0052] A pressing and discharging plate 6 is arranged on the driving mechanism 5 and is located on one side of the bottom of the guide wheel mechanism 45. The pressing and discharging plate 6 is connected to the inside of the high-pressure water tank 32 through a water delivery hose

[0053] It should be noted that a crawler-type traveling mechanism or a wheel-type traveling mechanism (not shown in the figure) is provided at the bottom of the mobile vehicle body 1 described in this embodiment. The built-in motor of the crawler-type traveling mechanism or the wheel-type traveling mechanism is electrically connected to a controller (not shown in the figure) provided on the mobile vehicle body 1. For the convenience of coordinated control, the double-notch mechanism 44, the driving mechanism 5, and the high-pressure water tank 32 are all electrically connected to a controller (not shown in the figure) on the mobile vehicle body 1.

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

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

[0056] It should be noted that a disinfectant is provided inside the cutting spike groove 31 described in this embodiment.

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

[0058] Specifically, through innovative integrated design, the present invention deeply integrates core functions such as disinfection, straightening, cutting, cutting, soil pressing, and watering, constructs a full-process operation system for cutting seedlings in saline-alkali land, significantly improves the cutting efficiency of seedlings in saline-alkali land, and effectively improves the survival rate of seedlings by precisely controlling parameters of each link (such as straightening force, incision angle, soil pressing depth, and watering amount). Its compact vehicle-mounted layout and convenient module characteristics significantly reduce the labor cost and equipment transfer difficulty of large-scale seedling cultivation in saline-alkali land, and show excellent practicability and reliability.

[0059] Taking Amorpha fruticosa long cuttings as an example, the full-process cutting operation is realized by using this device:

[0060] 1. Place the long cuttings in the cutting spike groove 31 and complete surface disinfection through the disinfectant in the groove;

[0061] 2. Drive the mobile vehicle body 1 to move to the target cutting area;

[0062] 3. Place the long cuttings in the side V-shaped feeding rack 41, then pull down the long cuttings so that their bottoms enter the conical feeding hopper 42, and then pass through the bottom of the conical feeding hopper 42 and enter the annular groove of the wheel-type straightening device 43;

[0063] 4. Start the driving mechanism 5, and the driving mechanism 5 controls the operation of each component according to the following time sequence:

[0064] Simultaneously start the wheel-type straightening device 43 and the guide wheel mechanism 45 to straighten the long cuttings and convey the short cuttings;

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

[0066] Simultaneously start the double-cutting mechanism 44 and the pressing plate 6 to achieve cutting and compaction and water injection of the long cuttings;

[0067] The wheel-type straightening device 43 applies an axial tensile force to the long cuttings through the annular groove to eliminate the bending stress. Subsequently, the double-cutting mechanism 44 completes the double-end cutting of the short cuttings, forming a flat top and an inclined bottom. The guide wheel mechanism 45 conveys the cut short cuttings to the lower part of the branch pressing mechanism 33, and the short cuttings are pressed into the soil through the branch pressing mechanism 33. Finally, the pressing plate 6 completes the soil compaction and watering operations.

[0068] In an embodiment of the present invention, as Figure 1 and Figure 4 shown, the branch pressing mechanism 33 includes a turntable 331 rotatably connected to the inner wall of the seat body 3. A pressing rod 332 is threadedly connected to the outer edge surface of the turntable 331. One end of the pressing rod 332 penetrates outside the seat body 3 and is located inside the guide wheel mechanism 45. One end of the central axis of the turntable 331 is fixedly connected to a one-way transmission 333, and the other end of the one-way transmission 333 is fixedly connected to a driving gear 334. The driving gear 334 is meshed with one end of the driving mechanism 5 penetrating into the seat body 3.

[0069] It should be noted that a strip-shaped groove is formed on the surface of the seat body 3 in this embodiment, and one end of the pressing rod 332 penetrates outside the seat body 3 through the strip-shaped groove.

[0070] Specifically, further illustrate the structure and connection relationship of the branch pressing mechanism 33. During use, when the lower tooth seat 56 in the driving mechanism 5 descends, it synchronously drives the second tooth portion 58 to descend. When the second tooth portion 58 descends, it synchronously drives the driving gear 334 to rotate. When the driving gear 334 rotates, it synchronously drives the turntable 331 to rotate through the one-way transmission 333. When the turntable 331 rotates, it synchronously drives the pressing rod 332 to rotate. During the rotation of the pressing rod 332, it presses down the short cuttings on the guide wheel mechanism 45 and presses them into the soil to achieve cutting.

[0071] In an embodiment of the present invention, as Figure 2 shown, the side V-shaped feeding rack 41 includes a fixing rack 411 fixedly connected to the surface of the seat body 3. A V-shaped groove 412 is formed on the surface of the fixing rack 411 facing the cutting spike groove 31. Elastic limiting pieces 413 are fixedly welded to the inner wall of the V-shaped groove 412;

[0072] The number of side V-shaped feeding racks 41 is at least three groups. The centers of the V-shaped grooves 412 on the three groups of side V-shaped feeding racks 41 and the center of the conical guiding hopper 42 are all on the same axis.

[0073] It should be noted that a weight-reducing groove is formed on the fixing rack 411 described in this embodiment.

[0074] Specifically, further illustrate the structure and connection relationship of the side V-shaped feeding rack 41. The fixing rack 411 is designed to be convenient for fixing on the seat body 3. The V-shaped groove 412 is designed to play a guiding role, facilitating the placement of the long cutting spike into the innermost part of the V-shaped groove 412. The elastic limiting piece 413 is designed to limit the long cutting spike placed in the innermost part of the V-shaped groove 412 to prevent it from shifting, ensuring that the axis of the long cutting spike and the center line of the annular groove always maintain high-precision coaxiality. By cooperating with the conical guiding hopper 42, the stability and the accuracy of inserting into the annular groove are significantly improved, and the use effect is good.

[0075] In an embodiment of the present invention, as Figure 1 and Figure 4 shown, the wheel-type straightening device 43 includes three groups of wheel set units 431 sequentially arranged on the surface of the seat body 3 in the vertical direction. The wheel set unit 431 includes a first driving wheel 432 and a second driving wheel 433. The first driving wheels 432 are symmetrically and oppositely arranged on the surface of the seat body 3 along the X-axis direction. The second driving wheels 433 are symmetrically and oppositely arranged on the surface of the seat body 3 along the Y-axis direction and are located on one side of the bottom of the first driving wheels 432. One end of the central axis of the two groups of first driving wheels 432 penetrates into the interior of the seat body 3 and is fixedly connected with an upper transmission gear 434. The two groups of upper transmission gears 434 are meshed with each other. One of the upper transmission gears 434 is meshed with one end of the driving mechanism 5 penetrating into the interior of the seat body 3;

[0076] The guide wheel mechanism 45 includes a first guide wheel 451 and a second guide wheel 452. The first guide wheels 451 are symmetrically and oppositely arranged on the surface of the seat body 3 along the X-axis direction and are located on one side of the bottom of the double-cutting mechanism 44. The second guide wheels 452 are symmetrically and oppositely arranged on the surface of the seat body 3 along the X-axis direction and are located on one side of the bottom of the first guide wheels 451. One end of the two groups of first guide wheels 451 penetrates into the interior of the seat body 3 and is fixedly connected with an inner driving gear 453. One of the inner driving gears 453 is meshed with one end of the driving mechanism 5 penetrating into the interior of the seat body 3. One end of the pressing rod 332 penetrating out of the seat body 3 is located between the two groups of second guide wheels 452.

[0077] It should be noted that the first driving wheel 432, the second driving wheel 433, the first guide wheel 451, and the second guide wheel 452 described in this embodiment are all elastic rollers. An annular groove adapted to the cuttings is provided on the outer circumferential surface of the elastic roller, and anti-slip lines are provided on the inner wall of the annular groove.

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

[0079] It should further be noted that one-way transmitters 333 are also provided between one end of the central axis of the first driving wheel 432 and the upper transmission gear 434, and between one end of the central axis of the first guide wheel 451 and the inner driving gear 453. The one-way transmitters 333 at this position are 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 described. During use, the upper tooth seat 55 and the lower tooth seat 56 on the driving mechanism 5 descend synchronously to drive the first tooth portion 57 to descend. The descent of the first tooth portion 57 synchronously drives the upper transmission gear 434 and the inner driving gear 453 to rotate. The rotation of the upper transmission gear 434 synchronously drives the first driving wheel 432 to rotate. Through cooperation with the second driving wheel 433, the straightening and conveying operations of the long cuttings are realized. The rotation of the inner driving gear 453 synchronously drives the first guide wheel 451 to rotate. Through cooperation with the second guide wheel 452, the conveying operation of the short cuttings is realized.

[0081] In an embodiment of the present invention, as Figures 6-7 shown, the double-cutting mechanism 44 includes a box body 441, a conical feed cup 442, an upper guide cylinder 443, a lower guide cylinder 444, a moving seat 445, a return spring 446, a guide groove 447, a flat-cutting knife 448, an inclined-cutting knife 449, and a blower 4410. Among them,

[0082] The box body 441 is fixedly connected to the surface of the seat body 3 and is located at one side of the bottom of the lowermost group of second driving wheels 433. The conical feeding 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 feeding cup 442. The moving seat 445 is horizontally slidably connected to the surface of the box body 441, and a return spring 446 is fixedly connected between the moving seat 445 and the surface of the box body 441. The guide groove 447 is opened on the surface of the moving seat 445. One end of the driving mechanism 5 is located in the guide groove 447 and is slidably connected to the inner wall of the guide groove 447. The flat cutting knife 448 and the bevel cutting knife 449 are respectively fixedly connected to the upper end surface and the lower end surface of the moving seat 445. One ends of the flat cutting knife 448 and the bevel cutting knife 449 respectively penetrate into the interior of the box body 441 and are in contact connection with the inner walls of the first notch 4431 and the second notch 4432 on the upper guide cylinder 443. The blower 4410 is arranged on the surface of the box body 441. The output end of the blower 4410 penetrates into the interior of the box body 441 and corresponds to the space position between the upper guide cylinder 443 and the lower guide cylinder 444.

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

[0084] It should also be noted that the surface of the box body 441 described in this embodiment is provided with notches facilitating the penetration of the flat cutting knife 448 and the bevel cutting knife 449 into the interior of the box body 441.

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

[0086] Specifically, the structure and connection relationship of the double-cutting mechanism 44 are further described. During use, when the convex shaft 510 in the driving mechanism 5 moves along the inner wall of the inclined section in the guide groove 447, it synchronously presses the moving seat 445 to move towards the box body 441 and compresses the return spring 446. The movement of the moving seat 445 synchronously drives the flat cutting knife 448 and the bevel cutting knife 449 into the interior of the box body 441, and cuts the long cuttings at the positions of the first notch 4431 and the second notch 4432. The cut short cuttings enter the guide wheel mechanism 45 and are conveyed by the guide wheel mechanism 45. The cut residues will be blown out of the box body 441 by the blower 4410.

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

[0088] Openings 4441 are provided at the corresponding positions of the bottom of the upper guide cylinder 443 and the top of the lower guide cylinder 444. The openings 4441 are located on the surface of the upper guide cylinder 443 and the lower guide cylinder 444 away from the fan 4410.

[0089] Specifically, the vertical section is designed so that when the driving mechanism 5 drives the wheel straightener 43, the guide wheel mechanism 45, and the branch pressing mechanism 33, it will not drive the double-cutting mechanism 44. The oblique section is designed so that when the driving mechanism 5 drives the double-cutting mechanism 44, it will not drive the wheel straightener 43, the guide wheel mechanism 45, and the branch pressing mechanism 33.

[0090] The design of the opening 4441 is such that after the long cutting spike is cut, the cut residue can be easily discharged from the inside of the upper guide cylinder 443 and the lower guide cylinder 444 under the blowing of the fan 4410, and the use effect is good.

[0091] In an embodiment of the present invention, as Figures 3-5 shown, the driving mechanism 5 includes a mounting base 51, a carriage 54, an upper tooth seat 55, a lower tooth seat 56, a second tooth portion 58, and a convex shaft 510. Among them, the mounting base 51 is fixedly connected to the surface of the seat body 3. Guide shafts 52 and a reciprocating screw rod 53 are respectively provided at the bottom of the mounting base 51. A driving motor is fixedly connected to the inner wall of the mounting base 51 and is connected to one end of the reciprocating screw rod 53. The carriage 54 is threadedly connected to the surface of the reciprocating screw rod 53 and is sleeved outside the guide shaft 52. The upper tooth seat 55 and the lower tooth seat 56 are respectively vertically slidably connected to the inner wall of the seat body 3. One ends of the upper tooth seat 55 and the lower tooth seat 56 respectively penetrate outside the seat body 3 and are fixedly connected to the surface of the carriage 54. First tooth portions 57 are respectively provided on the surfaces of the upper tooth seat 55 and the lower tooth seat 56. The first tooth portion 57 of the upper tooth 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 tooth seat 56 is located on one side of the inner driving gear 453 and is meshed with the inner driving gear 453. The second tooth portion 58 is integrally formed on the surface of the lower tooth seat 56 and is located on one side of the driving gear 334. The second tooth portion 58 is meshed with the driving gear 334. The convex shaft 510 is fixedly connected to the positioning seat 59 on the surface of the carriage 54. One end of the convex 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 sleeved on the limit guide rod 100 on the surface of the mobile vehicle body 1.

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

[0094] Specifically, the structure and connection relationship of the driving mechanism 5 will be further described. The driving mechanism 5 adopts a single-power design and can drive the wheel-type straightener 43, the double-cut mechanism 44, the guide-wheel mechanism 45, and the pressing plate 6 to cooperate in performing the cutting and inserting operation.

[0095] During use, the driving motor receives an instruction to operate, driving the reciprocating lead screw 53 to rotate synchronously. Under the guiding action of the guide shaft 52, the carriage 54 makes a reciprocating lifting motion along the outer surface of the reciprocating lead screw 53. When the carriage 54 descends, it drives the upper tooth seat 55, the lower tooth seat 56, and the convex shaft 510 to move downward synchronously. In the initial stage, the convex shaft 510 is located in the vertical section of the guide groove 447 in the double-cut mechanism 44. When the upper tooth seat 55 descends, the first tooth portion 57 on its surface drives the inner driving gear 453 of the guide-wheel mechanism 45 to rotate; during the descent of the lower tooth seat 56, the first tooth portion 57 on its surface also acts on the inner driving gear 453. At the same time, after a set delay time, the second tooth portion 58 drives the driving gear 334 to rotate. As the carriage 54 continues to descend, the convex shaft 510 moves from the vertical section of the guide groove 447 to the inclined section, pushing the moving seat 445 of the double-cut mechanism 44 towards the side 441 of the box body, realizing the linkage of each mechanism according to the preset program.

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

[0097] At the positions corresponding to the water injection pipes 61 at the bottom of the pressing plate 6, column grooves are respectively opened. The inner walls of the column grooves are fixedly connected with water seats 601, and the water seats 601 are connected to the inside of the pressing plate 6. The water injection pipes 61 are located in the column grooves, and compression springs 602 are fixedly connected between the water injection pipes 61 and the inner walls of the column grooves. One end of the water injection pipe 61 penetrates through the inside of the water inlet seat 601. Water inlet holes 603 are respectively opened at the positions corresponding to the inner wall of the water seat 601 on the surface of the end of the water injection pipe 61 penetrating through the inside of the water inlet seat 601, and they are connected. The other end of the water injection pipe 61 penetrates out of the column groove, and water outlet holes 604 are uniformly opened.

[0098] It should be noted that to ensure the precise docking and connection of the two groups of water inlet holes 603, the depth dimension 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, and the sealing ring is located outside the water inlet holes 603.

[0099] It should also be noted that 80-mesh stainless steel filters are installed inside the water outlet holes 604 to intercept soil particles and prevent blockage.

[0100] Specifically, the structure and connection relationship of the water injection pipe 61 will be further described. The water injection pipe 61 is designed to facilitate the injection of water into the soil around the short cuttings, improving the survival rate of the short cuttings. The water injection pipe 61 adopts a pressure-sensing adaptive water injection structure and is pressed down synchronously with the pressing and discharging plate 6. Its bottom gradually inserts into the soil around the short cuttings to cooperate with the pressing and discharging plate 6 to complete the compaction operation. During the downward movement, the compression spring 602 is compressed and contracted. When the upper water hole 603 on the outer wall of the water injection pipe 61 is aligned and connected with the upper water hole 603 on the inner wall of the water seat 601, the liquid in the high-pressure water tank 32 is automatically injected into the water injection pipe 61 under pressure and uniformly penetrates into the soil through the lower water hole 604. When the pressing and discharging plate 6 is lifted, the water injection pipe 61 is reset under the action of the compression spring 602, and the upper water hole 603 is quickly misaligned to achieve instantaneous interception. At the same time, an 80-mesh stainless steel filter screen is installed in the lower water hole 604 to intercept soil particles and prevent blockage. The overall design realizes the precise control and anti-leakage function of cutting irrigation in saline-alkali land through a three-level collaborative mechanism of mechanical linkage - pressure sensing - adaptive sealing.

[0101] The U-shaped groove 62 on the pressing and discharging plate 6 is designed to provide a running space for the pressure rod 332 to prevent it from conflicting with the stroke of the pressure rod 332, and the use effect is good.

[0102] In summary, for a rapid cutting device for seedlings in saline-alkali land in an embodiment of the present invention, through an innovative integrated design, the core functions such as disinfection, straightening, cutting, cutting, soil pressing, and watering are deeply integrated, constructing a full-process operation system for cutting seedlings in saline-alkali land, significantly improving the cutting efficiency of seedlings in saline-alkali land. By quickly connecting processes and precisely controlling the parameters of each link, the survival rate of seedlings is effectively improved. Its compact vehicle-mounted layout and convenient module characteristics significantly reduce the labor cost and equipment transfer difficulty of large-scale seedling cultivation in saline-alkali land, and the practicability and reliability are excellent.
