Description

Technical Field

[0001] This invention relates to the field of seedling planting equipment technology, specifically to an integrated device and method for planting seedlings in saline-alkali land. Background Technology

[0002] Saline-alkali land refers to soil types containing excessive soluble salts or alkaline substances, leading to deterioration of soil physical and chemical properties and low fertility. Seedling cultivation and planting are important means of improving and restoring saline-alkali land. By planting salt-tolerant seedlings in saline-alkali land, soil structure can be gradually improved and land productivity can be enhanced, which is of great significance to ecological environmental protection and sustainable agricultural development.

[0003] The unique soil environment of saline-alkali land presents numerous challenges to seedling planting. During the seedling planting process, the difficulty of digging planting pits is a major concern. In existing technologies, the pit digging and planting processes rely heavily on manual intervention, making it difficult to accurately control the size of the planting pits and the placement of seedlings according to the characteristics of the saline-alkali soil. This results in unstable planting quality, low work efficiency, and difficulty in achieving continuous planting operations, which increases labor costs and labor intensity, making it difficult to meet the needs of large-scale seedling planting in saline-alkali land. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an integrated device and method for planting seedlings in saline-alkali land, which solves the problems of unstable planting quality and low operational efficiency in saline-alkali land.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated device and method for planting seedlings in saline-alkali land, comprising a seedling rack, and further comprising:

[0013] Furthermore, the displacement assembly includes a base rod fixedly mounted on a rotating frame, a gripper rotatably mounted on the base rod, the gripper being provided with a meshing tooth groove, an extension frame fixedly mounted on the base rod, a second electric push rod fixedly mounted on the extension frame, a toothed plate fixedly mounted on the output shaft of the second electric push rod, the toothed plate being meshed with the meshing tooth groove, and a conveyor belt fixedly mounted on the seedling rack.

[0014] Furthermore, a collection assembly is provided on the fixed column. The collection assembly includes an installation groove formed on the fixed column, a movable rod slidably installed in the installation groove, one end of a return spring fixedly installed on the movable rod, the other end of the return spring being fixedly connected to the inner wall of the fixed column, a multi-stage sleeve fixedly installed on the movable rod, a collection frame fixedly installed on the multi-stage sleeve, and an adding assembly provided on the mounting plate. The connecting pipe included in the adding assembly can abut against the multi-stage sleeve.

[0015] Furthermore, the multi-stage sleeve consists of multiple hollow sleeves that are slidably connected, and the hollow sleeves are coaxial with the drill bit.

[0016] Furthermore, the adding component includes a storage bucket fixedly mounted on the mounting plate, the storage bucket containing fertilizer, and a connecting pipe fixedly connected to the storage bucket. The adding component also includes a rod slidably mounted on the connecting pipe, with a first magnetic block fixedly mounted at one end of the rod outside the connecting pipe. A connecting spring is fixedly mounted on the first magnetic block, and the other end of the connecting spring is fixedly connected to the connecting pipe. A push-out component is fixedly mounted at the end of the rod away from the first magnetic block. A connecting plate is fixedly mounted on the drill bit, and a second magnetic block cooperating with the first magnetic block is fixedly mounted on the connecting plate.

[0017] Furthermore, a backfilling assembly is provided inside the collection frame. The backfilling assembly includes a pair of third electric push rods fixedly installed on the collection frame.

[0018] Furthermore, a flexible actuating plate is fixedly installed on both the first guide member and the second guide member.

[0019] On the other hand, the present invention also provides a method for planting seedlings in saline-alkali land, which uses the above-mentioned integrated device for planting seedlings in saline-alkali land, and the method includes the following steps:

[0020] S1: The first motor of the switching component drives the drive gear to rotate, which in turn drives the gear sleeve and rotating frame to rotate, so that the pit-making component is aligned with the position to be dug. Then the first electric push rod pushes the mounting plate down, the second motor drives the drill bit to rotate and drill, and at the same time the multi-stage sleeve of the collection component moves down with the drill bit, and the collection frame collects the excavated soil.

[0021] S2: After the pit is made, the second electric push rod pushes the toothed plate to move, which engages with the meshing tooth groove of the gripper to open the gripper and grab the seedlings taken from the seedling rack and placed on the conveyor belt. After being moved to the top of the planting pit, the gripper is released and the seedlings are placed into the pit.

[0022] S3: The connecting pipe of the added component abuts against the collection frame. The repulsive force of the second magnetic block causes the first magnetic block to move the insertion rod. The pusher sends the fertilizer in the connecting pipe into the collection frame. Then the third electric pusher of the backfill component pushes the bottom plate. The first guide and the second guide move along the reverse guide groove, which drives the elastic agitator to mix the soil and fertilizer and backfill the pit and compact it.

[0023] The present invention has the following beneficial effects:

[0024] (1) The seedling rack with rollers is movable, the control cabinet coordinates the work of the components, the pit-making component drills holes, the relocation component moves seedlings, and the components work together to realize the integration of pit making and planting, reducing manual intervention and improving the basic efficiency of planting seedlings in saline-alkali land.

[0025] (2) In the switching component, the motor drives the gear to rotate the rotating frame, accurately switching the position of the pit making and displacement components. No overall moving device is required, realizing rapid process switching, reducing operation time and improving the smoothness of connection.

[0026] (3) In the shifting component, the electric push rod pushes the toothed plate, which drives the gripper to open and close to grab the seedlings conveyed by the conveyor belt and transfer them to the pit for placement. The mechanical transmission realizes stable grabbing and precise transfer, reduces errors and improves positioning accuracy.

[0027] (4) The collection components work synchronously with the pit making. When the drill bit is drilling, the collection frame is close to the ground to collect soil. When it is reset, it moves upward. The directional collection avoids pollution, provides convenience for backfilling, and improves the cleanliness of the working environment.

[0028] (5) When adding components, the magnetic force pushes the plug to send fertilizer into the collection box. When it moves away, the spring resets and closes the channel, which can accurately control fertilizer and avoid waste. Fertilizer is added in small amounts multiple times with the soil and mixed evenly to improve the fertilization effect.

[0029] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0052] The following is based on Figures 1-13This invention describes the integrated device and method for planting seedlings in saline-alkali land.

[0053] On one hand, this invention provides an integrated device for planting seedlings in saline-alkali land; please refer to [link / reference]. Figures 1-4 The integrated device for planting seedlings in saline-alkali land includes a seedling rack 10, on which rollers 11 are installed, and a control cabinet 12 is installed on the seedling rack 10.

[0054] It also includes: a planting hole assembly 30, which is located on one side of the seedling rack 10 and includes a drill bit 35 for digging planting holes;

[0055] Collection component 50 is located above the planting pit and is used to collect the soil generated during the construction of the pit.

[0056] The displacement component 40 is located on one side of the pit-making component 30 and is used to clamp or release the seedlings;

[0057] Switching component 20, which is installed on the seedling rack 10 and is used to switch the positions of the pit-making component 30 and the shifting component 40;

[0058] The backfilling component 70 is disposed within the collection frame 55 included in the collection component 50 and is used to backfill the soil in the collection component 50 after the seedling is released by the displacement component 40.

[0059] The pit-making assembly 30 includes a pair of first electric push rods 31 fixedly mounted on the rotating frame 23. A mounting plate 32 is fixedly mounted on the output end of the first electric push rods 31. A second motor 33 is fixedly mounted on the mounting plate 32. A fixing member 34 is fixedly mounted on the output shaft of the second motor 33. A drill bit 35 is fixedly connected to the fixing member 34.

[0060] When the device is in operation, the seedling rack 10 moves as a whole via the rollers 11 on it, facilitating operation in different areas of saline-alkali land. The control cabinet 12 is used to control the coordinated operation of each component. When planting is required, the switching component 20 drives the rotating frame 23 to rotate, causing the pit-making component 30 to move to the position to be operated. In the pit-making component 30, the first electric push rod 31 extends and retracts to push the mounting plate 32 down, while the second motor 33 drives the fixing part 34 and the drill bit 35 to rotate, drilling holes in the ground to form planting pits. After drilling is completed, the shifting component 40 on the rotating frame 23 moves to transfer the seedlings cultivated on the seedling rack 10 into the planting pits to complete the planting. Through the basic coordination of each component, the initial integration from pit making to planting is achieved, reducing manual intervention and improving the basic efficiency of seedling planting in saline-alkali land.

[0061] Please see Figure 2 and Figure 5The switching assembly 20 includes a mounting base 21 that is detachably and fixedly mounted on the seedling rack 10. A fixing column 22 is fixedly mounted on the mounting base 21. A rotating frame 23 is rotatably mounted on the fixing column 22. A gear sleeve 24 is fixedly mounted on the rotating frame 23. A first motor 25 is fixedly mounted on the mounting base 21. A drive gear 26 that meshes with the gear sleeve 24 is fixedly mounted on the output shaft of the first motor 25.

[0062] When the switching component 20 is working, the first motor 25 starts when it is necessary to switch between pit making and planting operations. Its output shaft drives the drive gear 26 to rotate. Since the drive gear 26 meshes with the gear sleeve 24 on the rotating frame 23, it drives the rotating frame 23 to rotate around the fixed column 22. By controlling the forward and reverse rotation and rotation angle of the first motor 25, the pit making component 30 or the shifting component 40 on the rotating frame 23 can be precisely switched to the working position, realizing the rapid switching between pit making and planting processes. There is no need to move the entire device to adjust its position, reducing the working time and improving the smoothness of process connection.

[0063] Please see Figure 1 and Figure 4 The shifting assembly 40 includes a base rod 41 fixedly mounted on a rotating frame 23, a gripper 42 rotatably mounted on the base rod 41, a meshing tooth groove 46 provided on the gripper 42, an extension frame 43 fixedly mounted on the base rod 41, a second electric push rod 44 fixedly mounted on the extension frame 43, a toothed plate 45 fixedly mounted on the output shaft of the second electric push rod 44, the toothed plate 45 meshing with the meshing tooth groove 46, and a conveyor belt 47 fixedly mounted on the seedling rack 10.

[0064] When the shifting component 40 is working, when it is necessary to grab a seedling, the second electric push rod 44 extends and retracts to push the toothed plate 45 to move along the extension frame 43. Because the toothed plate 45 engages with the meshing groove 46 on the gripper 42, the movement of the toothed plate 45 drives the gripper 42 to rotate around the base rod 41 to open and close. At the same time, the conveyor belt 47 on the seedling placement frame 10 transports the seedling to the gripping range of the gripper 42. After the gripper 42 closes to grab the seedling, it moves with the rotating frame 23 to the top of the planting pit. The second electric push rod 44 reverses its action to open the gripper 42 and put the seedling into the pit. Through the mechanical transmission of the electric push rod and the gear meshing, the seedling is stably grabbed and accurately transferred, reducing the error of manual seedling placement and improving the planting positioning accuracy.

[0065] Please see Figure 3 , Figure 7 and Figure 8The fixed column 22 is provided with a collection component 50. The collection component 50 includes a mounting groove 51 formed on the fixed column 22. A movable rod 52 is slidably installed in the mounting groove 51. One end of a return spring 53 is fixedly installed on the movable rod 52. The other end of the return spring 53 is fixedly connected to the inner wall of the fixed column 22. A multi-stage sleeve 54 is fixedly installed on the movable rod 52. A collection frame 55 is fixedly installed on the multi-stage sleeve 54. An adding component 60 is provided on the mounting plate 32. The connecting pipe 62 included in the adding component 60 can abut against the multi-stage sleeve 54.

[0066] The collection component 50 works synchronously with the pit-making component 30. As the drill bit 35 drills downwards, the connecting pipe 62 abuts against the multi-stage sleeve 54, causing the movable rod 52 to move downwards within the mounting groove 51, stretching the return spring 53. After the multi-stage sleeve 54 contacts the ground, it continuously shortens, bringing the collection frame 55 closer to the ground. During the pit-making process, the drill bit 35 continuously accumulates soil and enters the collection frame 55 along the multi-stage sleeve 54. When the drill bit 35 completes pit-making and returns to its original position, the connecting pipe 62 also moves accordingly. The return spring 53 rebounds, causing the movable rod 52 to move upwards, and the multi-stage sleeve 54 extends, causing the collection frame 55 to move upwards as well. This achieves directional collection of borehole soil, avoiding secondary pollution caused by soil scattering in saline-alkali land, while also facilitating subsequent backfilling and improving the cleanliness of the working environment.

[0067] Please see Figure 7 The multi-stage sleeve 54 consists of multiple hollow sleeves that are slidably connected, and the hollow sleeves are coaxial with the drill bit 35.

[0068] As the drill bit 35 drills down to different depths, the hollow sleeve can extend and retract synchronously with the drill bit 35, ensuring that the soil is always transported along the multi-stage sleeve 54. This structure is adapted to different drilling depths of the drill bit 35. Whether it is a shallow hole or a deep hole, it can ensure that the soil falls completely into the collection frame 55, avoiding soil scattering due to insufficient sleeve length, and significantly improving the integrity and efficiency of soil collection.

[0069] Please see Figure 11 and Figure 12The adding component 60 includes a storage tank 61 fixedly mounted on the mounting plate 32, the storage tank 61 containing fertilizer, and a connecting pipe 62 fixedly connected to the storage tank 61. The adding component 60 also includes an insert rod 63 slidably mounted on the connecting pipe 62. A first magnetic block 66 is fixedly mounted on one end of the insert rod 63 outside the connecting pipe 62. One end of a connecting spring 64 is fixedly mounted on the first magnetic block 66, and the other end of the connecting spring 64 is fixedly connected to the connecting pipe 62. A push-out member 65 is fixedly mounted on the end of the insert rod 63 away from the first magnetic block 66. A connecting plate 68 is fixedly mounted on the drill bit 35, and a second magnetic block 67 that cooperates with the first magnetic block 66 is fixedly mounted on the connecting plate 68.

[0070] When fertilizer needs to be added, the fertilizer in the storage tank 61 enters the connecting pipe 62. When the drill bit 35 moves the connecting plate 68 and the second magnetic block 67 close to the connecting pipe 62, the second magnetic block 67 and the first magnetic block 66 generate a magnetic force, pushing the first magnetic block 66 to compress the connecting spring 64, causing the insertion rod 63 to slide along the connecting pipe 62, so that the pusher 65 moves inside the connecting pipe 62. The pusher 65 pushes the fertilizer in the connecting pipe 62 into the collection frame 55. When the drill bit 35 moves away, the connecting spring 64 rebounds, causing the insertion rod 63 to reset and closing the fertilizer channel. With a rapid response and without the need for additional power, precise control of fertilizer addition is achieved, avoiding waste. Furthermore, as soil continuously enters the collection frame 55, fertilizer is added in small amounts multiple times, allowing the fertilizer to be evenly mixed into the soil and improving the fertilization effect.

[0071] Please see Figure 9 The collection frame 55 is provided with a backfilling component 70. The backfilling component 70 includes a pair of third electric push rods 71 ​​fixedly installed on the collection frame 55. A base plate 72 is fixedly installed on the output shaft of the third electric push rods 71. A first guide member 73 is rotatably installed on the base plate 72. A first guide groove 75 that cooperates with the first guide member 73 is opened on the collection frame 55. A second guide member 74 is rotatably installed on the base plate 72. A second guide groove 76 that cooperates with the second guide member 74 is opened on the collection frame 55. The first guide groove 75 and the second guide groove 76 have opposite directions.

[0072] When the backfilling component 70 is working, the third electric push rod 71 extends and retracts to push the base plate 72 up and down. The first guide member 73 on the base plate 72 slides along the first guide groove 75 on the collection frame 55, and the second guide member 74 slides along the second guide groove 76. Since the two guide grooves guide in opposite directions, the first guide member 73 and the second guide member 74 move in opposite directions when they move, so as to realize the mixing and pushing of the soil in the collection frame 55. When the soil is pushed to a certain height, the soil is backfilled into the planting pit along the first guide member 73, the second guide member 74 and the multi-stage sleeve 54. At the same time, it is ensured that the soil can fully cover the seedling roots during backfilling and improve the compaction of the backfill.

[0073] An elastic actuating plate 77 is fixedly installed on both the first guide member 73 and the second guide member 74.

[0074] The elastic agitator plates 77 on the first guide member 73 and the second guide member 74 contact and swing as the guide members move in the opposite direction. When the first guide member 73 and the second guide member 74 move, the elastic agitator plates 77 can adapt to the resistance of the soil due to their own elastic deformation, and fully mix the soil and fertilizer in the collection frame 55. At the same time, after the adjacent elastic agitator plates 77 contact, they will swing again, so that the fertilizer and the saline-alkali soil are evenly mixed.

[0075] When in use (working), the seedling rack 10 is moved to the working area by the rollers 11, and the control cabinet 12 coordinates the start of each component;

[0076] In the switching component 20, the first motor 25 drives the drive gear 26 to mesh with the gear sleeve 24, which in turn drives the rotating frame 23 to rotate around the fixed column 22, so that the pit-making component 30 is aligned with the position to be dug.

[0077] When the pit-making component 30 is working, the first electric push rod 31 pushes the mounting plate 32 to move down, the second motor 33 drives the fixing part 34 and the drill bit 35 to rotate and drill, and at the same time the multi-stage sleeve 54 of the collecting component 50 moves down with the drill bit 35, and the collecting frame 55 collects the soil.

[0078] After the planting pit is completed, the switching component 20 drives the rotating frame 23 to switch to the shifting component 40: the second electric push rod 44 pushes the toothed plate 45, which cooperates with the meshing tooth groove 46 of the gripper 42, so that the gripper 42 opens, grabs the seedlings conveyed by the conveyor belt 47, moves them above the planting pit and then releases them.

[0079] Adding component 60 works: The second magnetic block 67 on the drill bit 35 interacts with the first magnetic block 66 on the connecting pipe 62, driving the insertion rod 63 and the ejector 65 to move, sending the fertilizer in the storage bucket 61 into the collection frame 55 through the connecting pipe 62;

[0080] Backfilling component 70 works: the third electric push rod 71 pushes the base plate 72, the first guide 73 moves in the opposite direction along the first guide groove 75 and the second guide 74 moves in the opposite direction along the second guide groove 76, driving the elastic agitator 77 to mix the soil and fertilizer, and backfill the mixture into the pit.

[0081] After the operation is completed, all components are reset and the device is moved to the next work point.

[0082] On the other hand, the present invention also provides a method for planting seedlings in saline-alkali land, which uses the above-mentioned integrated device for planting seedlings in saline-alkali land, and the method includes the following steps:

[0083] S1: The first motor 25 of the switching component 20 drives the drive gear 26 to rotate, which in turn drives the gear sleeve 24 and the rotating frame 23 to rotate, so that the pit-making component 30 is aligned with the position to be dug. Then, the first electric push rod 31 pushes the mounting plate 32 to move down, and the second motor 33 drives the drill bit 35 to rotate and drill. At the same time, the multi-stage sleeve 54 of the collecting component 50 moves down with the drill bit 35, and the collecting frame 55 collects the excavated soil.

[0084] S2: After the pit is made, the second electric push rod 44 pushes the toothed plate 45 to move, which cooperates with the meshing tooth groove 46 of the gripper 42 to open the gripper 42 and grab the seedlings taken from the seedling rack 10 and placed on the conveyor belt 47. After being moved to the top of the planting pit, the gripper is released and the seedlings are placed into the pit.

[0085] S3: The connecting pipe 62 of the added component 60 abuts against the collection frame 55. The repulsive force of the second magnetic block 67 causes the first magnetic block 66 to move the insertion rod 63. The pusher 65 sends the fertilizer in the connecting pipe 62 into the collection frame 55. Then, the third electric pusher 71 of the backfilling component 70 pushes the bottom plate 72. The first guide 73 and the second guide 74 move along the reverse guide groove, driving the elastic agitator 77 to mix the soil and fertilizer and backfill the pit and compact it.
