Description

Technical Field

[0001] This invention relates to the field of seedling transplanting technology, and in particular to a seedling transplanting device and method for high-altitude areas. Background Technology

[0002] Currently, seedling cultivation requires transplanting. Transplanting can expand the nutritional space for seedling growth, such as light space, ventilation space, and branch growth space, as well as the space for root growth, water and nutrient absorption. Transplanting can also stimulate the development of seedling root system, produce more fibrous roots, and improve the survival rate of greening.

[0003] A search revealed a Chinese patent publication number CN 114793694 A, which discloses an integrated device for cultivating and transplanting Camellia chrysantha seedlings. The device includes a mobile frame with multiple wheels at its bottom. Multiple cultivation mechanisms are mounted on the upper side of the mobile frame via uprights. Each cultivation mechanism has a conveying mechanism on its lower side. Multiple conveying pipes are shared on the rear sides of the conveying and cultivation mechanisms. Each conveying pipe has an inlet corresponding to a conveying mechanism on its front side and an outlet at its bottom. A lifting frame is mounted on the front of the mobile frame, and multiple soil breakers are movably mounted on the lower side of the lifting frame.

[0004] The above-mentioned patent has the following shortcomings: its soil breaker directly drills and breaks the soil. Since there is a lot of frozen soil in high-altitude areas, direct drilling will result in greater resistance, which leads to low soil breaking efficiency and also reduces the service life of the components. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a seedling transplanting device and method for high-altitude areas.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A seedling transplanting device for high-altitude areas includes a chassis and a tracked walking mechanism set on both sides of the bottom of the chassis. The top of the chassis is provided with a soil breaking mechanism for breaking the soil and making holes, a material picking and discharging mechanism for picking up and discharging materials, and a multi-station material storage and conveying mechanism for storing and transporting seedlings, respectively, from the front right to the rear. The soil-breaking mechanism includes a fixed frame fixed to the front end of the chassis and a lifting frame connected to the bottom of the fixed frame via a telescopic device. The inner wall of the lifting frame is rotatably connected with multiple spiral blades. A worm wheel is fixed to the top outer wall of the spiral blades. A motor is fixed to the top outer wall of the lifting frame by bolts. The output shaft of the motor is fixed with a worm that meshes with the side wall of the worm wheel. The tip of the spiral blade is tapered, and the tapered area of ​​the spiral blade is made of conductive material. When the tapered area of ​​the spiral blade conducts electricity, it generates Joule heat. In addition, a ground-breaking shaft is fixed to the outer wall of the spiral blade. A power generation winding is fixed to the upper outer wall of the spiral blade. A power generation iron core that cooperates with the power generation winding is fixed to the outer wall of the lifting frame located around the power generation winding. The output end of the power generation winding is electrically connected to the input end of the conical region of the spiral blade. When the power generation winding rotates relative to the power generation iron core, it can generate an induced electromotive force by cutting the magnetic field of the power generation winding.

[0007] Preferably, the multi-station integrated material storage and conveying mechanism includes an electric turntable, multiple corner plates, and multiple integrated material storage and conveying components. The electric turntable is driven and mounted on the top outer wall of the chassis. The multiple corner plates are fixed to the top outer wall of the electric turntable in a circular array, and the integrated material storage and conveying components are disposed between two adjacent corner plates.

[0008] Furthermore, the integrated material storage and conveying assembly includes two sets of chain drive assemblies respectively disposed on opposite sides of two adjacent corner plates and multiple support frames. Both sides of the multiple support frames are rotatably connected to hinge shafts, which are fixed to the chain links of the chain drive assemblies. The top outer wall of each support frame is provided with multiple seedling limiting platforms for placing seedlings.

[0009] Based on the aforementioned scheme: the chain shaft at the bottom of the chain drive assembly is connected to the drive shaft via a bevel gear set 1. The drive shaft is rotatably connected to the inner wall of the electric turntable 1. A semi-magnetic coupler 1 is fixed at the bottom of the drive shaft. A drive shaft is rotatably connected to the top of the chassis. A semi-magnetic coupler 2 that cooperates with the semi-magnetic coupler 1 is fixed at the top of the drive shaft. The semi-magnetic coupler 2 and a semi-magnetic coupler 1 form a magnetic coupler.

[0010] A preferred embodiment of the aforementioned scheme is that a drive assembly is provided on one side of the chassis, the drive assembly including a second electric motor and a second bevel gear set, one side of the drive shaft is connected to the second electric motor via the second bevel gear set, and the second electric motor is fixed to the top outer wall of the chassis by bolts.

[0011] As a further aspect of the present invention: each of the transmission shafts has a set of locking components on its outer wall. The locking components include a fixed ring, an inner ring and an outer ring arranged concentrically. The fixed ring is fixed to the bottom outer wall of the electric turntable, the inner ring is fixed to the outer wall of the transmission shaft, and the outer ring is rotatably connected between the fixed ring and the inner ring. The outer ring and the inner ring have sliding damping.

[0012] Meanwhile, the inner ring is radially slidably connected with multiple toothed blocks, and the inner wall of the fixing ring is provided with toothed grooves that mesh with the toothed blocks. The side of the toothed block away from the toothed groove is connected to the outer wall of the inner ring by a pull rope.

[0013] As a preferred embodiment of the present invention, a spring is fastened to one side of the toothed block, and the other end of the spring is fastened to the inner wall of the outer ring.

[0014] Meanwhile, the material handling mechanism includes an electric turntable II and a mechanical arm fixed to the top of the electric turntable II. The moving end of the mechanical arm is fixed with a plate, and one side of the plate is fixed with multiple grippers for gripping seedlings.

[0015] A method for transplanting seedlings in high-altitude areas includes the following steps: S1: Seedling cultivation, which involves nurturing seedlings in a sunroom or other seedling cultivation device; S2: Transplanting, which involves transferring the cultivated seedlings to a high-altitude seedling transplanting device and then transplanting them using the high-altitude seedling transplanting device. S3: Maintenance, after transplanting, cover the pit with soil and perform other maintenance; The beneficial effects of this invention are as follows: 1. This invention uses spiral blades to break up soil, and the conical area of ​​the spiral blades can be electrically heated to soften frozen soil, thereby increasing the efficiency of breaking up soil and the life of components. In addition, the spiral blades are powered by a generator winding, and the generator winding rotates synchronously with the spiral blades, which solves the power supply problem and also prevents problems such as wire entanglement caused by traditional wire connections, thus increasing safety. Furthermore, the power switch and the rotation switch of the spiral blades can be controlled synchronously and comprehensively, simplifying the control logic.

[0016] 2. The present invention, by setting up multiple sets of integrated storage and conveying components, can switch working positions through the rotation of an electric turntable, and through the movement of the chain drive component, can switch working positions of different seedling limiting platforms within the same set of integrated storage and conveying components, thereby achieving centralized storage, ensuring the amount of seedlings stored in a single operation, eliminating the need to replenish seedlings by going back and forth, and increasing transplanting efficiency.

[0017] 3. This invention, based on the principle of magnetic coupling between semi-magnetic coupler one and semi-magnetic coupler two, enables the switching of positions of different integrated material storage and conveying components by using a single set of motor two, thereby simplifying the power layout and realizing automatic coupling and decoupling based on position, increasing convenience.

[0018] 4. In this invention, by setting a locking component, the second motor in the integrated material storage and conveying component can be relatively locked by damping when it is not driven by a rotational torque, thus ensuring the stability of its position. At the same time, when it is driven by a rotational torque, it can also automatically engage the lock, ensuring the reliability of the seedling limiting platform position switching.

[0021] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown 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 are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example 1: A seedling transplanting device and method for high-altitude areas, such as Figures 1-7As shown, it includes a chassis 1 and tracked walking mechanisms 5 set on both sides of the bottom of the chassis 1. The chassis 1 is provided with a soil breaking mechanism 2 for breaking soil and making pits, a material picking and discharging mechanism 3 for picking up and discharging materials, and a multi-station material storage and conveying mechanism 4 for storing and conveying seedlings, respectively, from the front right to the rear.

[0024] The soil-breaking mechanism 2 includes a fixed frame 6 fixed to the front end of the chassis 1 and a lifting frame 8 connected to the bottom of the fixed frame 6 via a telescopic device 7. The inner wall of the lifting frame 8 is rotatably connected with multiple spiral blades 9. The top outer wall of the spiral blades 9 is fixed with a worm gear 14, and the top outer wall of the lifting frame 8 is fixed with a motor 13 by bolts. The output shaft of the motor 13 is fixed with a worm 15 meshing with the side wall of the worm gear 14.

[0025] The end of the spiral blade 9 is tapered, and the tapered area of ​​the spiral blade 9 is made of conductive material. At the same time, the tapered area of ​​the spiral blade 9 generates Joule heat when conducting electricity. In addition, the outer wall of the spiral blade 9 is also fixed with a ground-breaking shaft 10.

[0026] A power generation winding 11 is fixed on the upper outer wall of the spiral blade 9. A power generation iron core 12 that cooperates with the power generation winding 11 is fixed on the outer wall of the lifting frame 8 located around the power generation winding 11. The output end of the power generation winding 11 is electrically connected to the input end of the conical region of the spiral blade 9. When the power generation winding 11 rotates relative to the power generation iron core 12, it can generate an induced electromotive force by cutting the magnetic field of the power generation winding 11.

[0027] When in use, the seedlings can be stored on the multi-station integrated storage and conveying mechanism 4, and the device can be moved to the transplanting area by the crawler walking mechanism 5. Then, the lifting frame 8 is lowered by the telescopic device 7. At the same time, the motor 13 starts and drives the worm gear 15 to rotate. The worm gear 15 drives the spiral blade 9 to rotate through the worm wheel 14. The conical area at the bottom of the spiral blade 9 is used to break the soil. At the same time, when the power generation winding 11 rotates relative to the power generation iron core 12, it can generate an induced electromotive force by cutting the magnetic field of the power generation winding 11 and apply it to the conical area of ​​the spiral blade 9. The conical area generates Joule heat and heats up the frozen soil to soften it. After breaking the soil and digging the pit, the device moves, and then the material handling mechanism 3 takes out the seedlings from the multi-station integrated storage and conveying mechanism 4 and places them in the pit.

[0028] This device breaks the soil by setting up a spiral blade 9. At the same time, the conical area of ​​the spiral blade 9 can be electrified to generate heat and soften the frozen soil, thereby increasing the efficiency of soil breaking and the life of the components. In addition, the spiral blade 9 is powered by a power generation winding 11, which rotates synchronously with the spiral blade 9. This solves the power supply problem and also prevents problems such as wire entanglement caused by traditional wire connections, thus increasing safety. Furthermore, the power switch and the rotation switch of the spiral blade 9 can be controlled synchronously and comprehensively, simplifying the control logic.

[0029] To solve the storage problem; such as Figures 3-5 As shown, the multi-station integrated storage and conveying mechanism 4 includes an electric turntable 16, multiple corner plates 18, and multiple integrated storage and conveying components 19. The electric turntable 16 is driven and mounted on the top outer wall of the chassis 1. The multiple corner plates 18 are fixed in a circular array on the top outer wall of the electric turntable 16, and the integrated storage and conveying components 19 are disposed between two adjacent corner plates 18.

[0030] The integrated material storage and conveying assembly 19 includes two sets of chain drive assemblies 23 respectively disposed on opposite sides of two adjacent corner plates 18 and multiple support frames 22. Both sides of the multiple support frames 22 are rotatably connected to hinge shafts 20, which are fixed to the chain links of the chain drive assembly 23. The top outer wall of each support frame 22 is provided with multiple seedling limiting platforms 21 for placing seedlings.

[0031] The chain shaft at the bottom of the chain drive assembly 23 is connected to the drive shaft 25 via a bevel gear set 24. The drive shaft 25 is rotatably connected to the inner wall of the electric turntable 16. A semi-magnetic coupler 27 is fixedly provided at the bottom of the drive shaft 25. A drive shaft 29 is rotatably connected to the top of the chassis 1. A semi-magnetic coupler 28 that cooperates with the semi-magnetic coupler 27 is fixedly provided at the top of the drive shaft 29. The semi-magnetic coupler 28 and the semi-magnetic coupler 27 form a magnetic coupler.

[0032] A drive assembly is provided on one side of the chassis 1. The drive assembly includes a second motor 32 and a second bevel gear set 31. One side of the drive shaft 29 is connected to the second motor 32 via the second bevel gear set 31. The second motor 32 is fixed to the top outer wall of the chassis 1 by bolts.

[0033] Before transplanting, seedlings can be placed in batches inside the seedling limiting platform 21. During transplanting, the electric turntable 16 first rotates, positioning one set of integrated storage and conveying components 19 facing the material handling mechanism 3. At this time, the semi-magnetic coupler 27 at the bottom of the drive shaft 25 of this integrated storage and conveying component 19 engages with the semi-magnetic coupler 28. Subsequently, the material handling mechanism 3 retrieves seedlings from one of the seedling limiting platforms 21 at one height. After retrieval, the motor 32 starts, driving the drive shaft 29 to rotate via the bevel gear set 31, thereby facilitating the semi-magnetic coupling. The cooperation between device 28 and semi-magnetic coupler 27 drives the transmission shaft 25 to rotate, and then drives the motor 32 to move through bevel gear set 24, thereby moving the next seedling limiting platform 21 loaded with seedlings to the picking height of the picking and dispensing mechanism 3. This process is repeated until all the seedlings in the integrated storage and conveying assembly 19 are picked up. Then, the electric turntable 16 continues to rotate to move the next integrated storage and conveying assembly 19 to the position facing the picking and dispensing mechanism 3. The above steps are repeated until all the seedlings stored in the integrated storage and conveying assembly 19 are picked up.

[0034] This device, by setting up multiple sets of integrated storage and conveying components 19, can switch work positions through the rotation of the electric turntable 16, and through the movement of the chain drive component 23, it can switch work positions of different seedling limiting platforms 21 within the same set of integrated storage and conveying components 19, thereby achieving centralized storage, ensuring the amount of seedlings stored in a single operation, eliminating the need to replenish seedlings by going back and forth, and increasing transplanting efficiency.

[0035] In addition, this device utilizes the principle of magnetic coupling between semi-magnetic coupler 27 and semi-magnetic coupler 28 to achieve position switching of different storage and conveying integrated components 19 by driving a single set of motors 32, thereby simplifying the power layout and realizing automatic coupling and decoupling based on position, increasing convenience.

[0036] To solve the locking problem; such as Figure 5 As shown, each of the drive shafts 25 has a locking assembly 26 fitted to its outer wall. The locking assembly 26 includes a fixed ring 33, an inner ring 34, and an outer ring 35 arranged concentrically. The fixed ring 33 is fixed to the bottom outer wall of the electric turntable 16. The inner ring 34 is fixed to the outer wall of the drive shaft 25. The outer ring 35 is rotatably connected between the fixed ring 33 and the inner ring 34, and there is sliding damping between the outer ring 35 and the inner ring 34. The inner ring 34 is radially slidably connected with a plurality of toothed blocks 37. The inner wall of the fixed ring 33 has a toothed groove 36 that meshes with the toothed blocks 37. The side of the toothed block 37 away from the toothed groove 36 is connected to the outer wall of the inner ring 34 by a pull rope 39. A spring 38 is fastened to one side of the toothed block 37, and the other end of the spring 38 is fastened to the inner wall of the outer ring 35.

[0037] When the drive shaft 25 is not driven by rotation, the toothed block 37 is engaged in the tooth groove 36 by the elastic force of the spring 38. At this time, due to the rotational damping between the inner ring 34 and the outer ring 35, the relative locking between the drive shaft 25 and the electric turntable 16 is achieved by the damping, thereby preventing the motor 2 32 from moving. When the drive shaft 25 is driven by rotation, since the outer ring 35 and the fixed ring 33 are hard locked, while the outer ring 35 and the inner ring 34 are damped locked, when the rotational driving force on the drive shaft 25 is greater than the damping force, the drive shaft 25 first drives the inner ring 34 to rotate, so that the toothed block 37 is pulled out of the tooth groove 36 by the spring 38, so that the outer ring 35 and the fixed ring 33 are unlocked.

[0038] This device, by setting a locking component 26, enables the motor 32 in the integrated material storage and conveying component 19 to be relatively locked by damping when it is not driven by a rotational torque, thus ensuring the stability of its position. At the same time, when it is driven by a rotational torque, it can also automatically engage the lock, ensuring the reliability of the position switching of the seedling limiting platform 21.

[0039] To solve the problem of material handling; such as Figure 7 As shown, the material handling mechanism 3 includes an electric turntable 40 and a mechanical arm 41 fixed to the top of the electric turntable 40. The moving end of the mechanical arm 41 is fixed with a plate 42, and a plurality of grippers 30 for gripping seedlings are fixed on one side of the plate 42.

[0040] The seedlings can be gripped by the gripper 30, and then released by the rotation of the electric turntable 40 and the movement of the robotic arm 41.

[0041] In this embodiment, seedlings can be stored on the multi-station integrated storage and conveying mechanism 4, and the device can be moved to the transplanting area by the crawler walking mechanism 5. Then, the lifting frame 8 is lowered by the telescopic device 7. At the same time, the motor 13 starts and drives the worm gear 15 to rotate. The worm gear 15 drives the spiral blade 9 to rotate through the worm wheel 14. The conical area at the bottom of the spiral blade 9 is used to break the soil. At the same time, when the power generation winding 11 rotates relative to the power generation core 12, it can generate an induced electromotive force by cutting the magnetic field of the power generation winding 11 and apply it to the conical area of ​​the spiral blade 9. The conical area generates Joule heating and transfers the temperature to the frozen soil to heat and soften it. After breaking the soil and digging the pit, when transplanting, the electric turntable 16 first rotates, so that one set of integrated storage and conveying components 19 faces the position of the picking and dispensing mechanism 3. At this time, the bottom of the drive shaft 25 of this set of integrated storage and conveying components 19 is... The first half-magnetic coupler 27 and the second half-magnetic coupler 28 cooperate, and then the picking and unloading mechanism 3 picks up the seedlings in the seedling limiting platform 21 at one of the heights. After picking up the seedlings, the second motor 32 starts, which drives the drive shaft 29 to rotate through the bevel gear set 31. In turn, the second half-magnetic coupler 28 and the first half-magnetic coupler 27 cooperate to drive the transmission shaft 25 to rotate. Then, the first bevel gear set 24 drives the second motor 32 to move, thereby moving the next seedling limiting platform 21 loaded with seedlings to the picking height of the picking and unloading mechanism 3. This process is repeated until all the seedlings in the integrated storage and conveying assembly 19 are picked up. Then, the electric turntable 16 continues to rotate to move the next integrated storage and conveying assembly 19 to the position facing the picking and unloading mechanism 3. Then, the above steps are repeated until all the seedlings stored in the integrated storage and conveying assembly 19 are picked up.

S3: Maintenance. After transplanting, cover the holes with soil and perform other maintenance.
