TECHNICAL FIELD

[0001] The application belongs to the technical field of agricultural planting machinery, and particularly relates to a salt-alkali soil irrigated grass no-tillage and hole-planting integrated machine. BACKGROUND

[0002] As an important reserve land resource in China, the ecological restoration and vegetation reconstruction of salt-alkali soil have strategic significance for improving the regional ecological environment and guaranteeing food security. The irrigated grass mixed planting mode has become an optimal scheme for the vegetation restoration of salt-alkali soil due to the synergistic advantages of soil fixation and sand prevention of shrubs and rapid coverage of herbaceous plants. However, the salt-alkali soil has the characteristics of poor structure, high salt content and poor permeability. When there is no water, the soil is hard, and after irrigation, the soil expands and becomes soft. The adaptability and functionality of the planting machinery are strictly required. At present, in the planting operation of salt-alkali soil, the traditional manual planting mode has the problems of high labor intensity and low efficiency, and is difficult to meet the needs of large-scale ecological restoration. The existing mechanical equipment has the technical limitations of single function and incoherent operation process.

[0003] The prior art, such as the salt and alkali land high-yield corn film mulching and hole planting machine disclosed in the announcement No. CN208462315U, although realizes the integration of film mulching and hole planting, its structure mainly comprises a rack, a film mulching device, a seeding device and a seeding pressure roller, first film mulching and then hole planting can achieve the phenomena of seedling free and thinning free during film mulching and seeding, and the seeding pressure roller on one side of the seeding device prevents the soil from sliding to both sides during seeding, however, the device can only complete the film mulching and seeding operations, and the subsequent soil covering and compaction still need to be completed by manual or additional equipment, and lacks a modified functional module for the characteristics of salt and alkali land; for example, the salt and alkali land pasture no-tillage seeding machine disclosed in the announcement No. CN208258334U, its structure comprises a base, a connecting column, a limiting bolt, a support frame, a hopper, an outer shell, a motor, a transmission shaft and an impeller, the grass seeds are dropped and seeded by rotating the impeller driven by the motor, suitable carriers can be replaced according to different terrains, and the seeds can automatically drop after the grass seed box is placed, but the device is also single in function and can only complete the seeding operation, and cannot simultaneously realize the integration of punching, seedling planting, root enhancer spraying, soil covering and compaction, in actual application, the salt and alkali land grass planting needs to go through multiple links of punching, seedling planting, root enhancer spraying, soil covering and compaction, if the above-mentioned traditional device is used for operation, manual or mechanical soil covering and compaction must be arranged after punching or seeding, multiple back-and-forth operations not only seriously disturb the fragile soil structure of the salt and alkali land, intensify the salt aggregation phenomenon, but also make the seedlings difficult to root in the salt and alkali environment due to the lack of root enhancer, and the survival rate is difficult to guarantee, at the same time, multiple ground operations cause the operation cycle to be prolonged, the cost to be increased, and the overall efficiency to be limitedly improved, in addition, the existing devices lack self-adaptive design for the complex working conditions of salt and alkali land, when facing the working environment of uneven ground surface and uneven soil hardness, it is difficult to guarantee the consistency of drilling depth, the accuracy of seedling planting position and the uniformity of soil covering thickness, which further affects the planting quality and the survival rate of seedlings, therefore, developing a salt and alkali land grass planting device capable of integrating the functions of punching, seedling planting, root enhancer spraying, soil covering and compaction in one body and having mechanical linkage control and self-adaptive adjustment capacity has become a technical problem to be solved in the field.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention innovatively integrates five core functions—no-till reseeding, shrub seedling planting, root-promoting liquid spraying, soil covering, and compaction—into one unit, completely changing the traditional equipment's single-function nature and the need for multiple round trips. The equipment uses the no-till reseeding machine itself as its base, and through a linkage structure of a U-shaped mounting frame, servo motor, strip rod, and triangular groove, it achieves an automatic cycle of lowering, drilling, and resetting the drilling platform as the equipment moves. Combined with the precise seedling delivery mechanism, the synchronous liquid spraying from the ring pipe, the automatic soil covering by the covering plate, and the progressive compaction by the compaction roller, it forms a fully automated operation chain of drilling-seedling-liquid spraying-soil covering-compacting. No additional manual intervention or multi-equipment collaboration is required; a single machine can complete the entire process of shrub-grass mixed sowing, significantly shortening the operation cycle. It is particularly suitable for large-scale saline-alkali land ecological restoration projects. Furthermore, the no-till operation mode avoids repeated soil disturbance, effectively protecting the fragile soil structure of saline-alkali land, reducing salt accumulation, and creating a stable soil environment for seedling growth. This solves the industry pain point of traditional multiple operations leading to increased salinization. This invention achieves precise control over the entire process from drilling and seedling placement to soil covering and compaction through a multi-component collaborative design. In the drilling stage, a drive motor directly drives the drilling drill, and the guide and limiting mechanisms of the strip groove, sliding block, and fixed support ensure consistent drilling depth and precise positioning, preventing seedling planting from being affected by hole misalignment or insufficient depth. In the seedling placement stage, the seedling delivery pipe is installed at an angle, precisely engaging with the quantitative seedling delivery mechanism when the drilling platform resets, achieving directional delivery of individual seedlings and eliminating the phenomenon of multiple or missed seedlings. In the spraying stage, a T-shaped... The connecting slide bar ensures precise alignment of the connecting groove and waist groove of the feeding pipe and the connecting pipe. Multiple nozzles of the ring pipe evenly surround the seedling delivery pipe, so that the root-promoting liquid covers the roots and stems in all directions, improving the seedlings' salt and alkali resistance. In the soil covering and compaction process, the soil covering plate moves precisely along the fixed guide rod to ensure uniform soil covering thickness. The compaction roller rotates and gathers the soil gradually, which ensures close contact between the soil and the roots, while avoiding excessive compaction that could damage the roots. This multi-dimensional precision control increases the seedling survival rate by more than 90% compared to traditional equipment, and significantly optimizes the planting quality. This invention replaces a complex electrical control system with a mechanical linkage design. Each function is automatically triggered through the mechanical cooperation between components, resulting in a simple structure and high reliability. The lifting and lowering of the drilling platform is achieved through the inclined guide of the triangular groove and the sliding connecting rod. The on / off of the root-enhancing liquid delivery relies on the sliding cooperation between the connecting pipe and the discharge pipe. The soil covering action is triggered by the upward movement of the fixed plate driving the inclined rod. The rotation and convergence of the compaction roller are achieved through the coordination of the spiral groove, gear, gear ring and abutment control ring. No complex sensors or control systems are required. This design not only reduces the equipment manufacturing cost, but also reduces the risk of failure of electrical control components in the harsh environment of saline-alkali land. During operation, only basic parameters need to be set through the control panel to achieve automated continuous operation, reducing the skill requirements for operators. At the same time, the modular design of each component, such as the liquid storage tank, soil covering plate, compaction roller, etc., can be independently disassembled and replaced, making maintenance convenient and further reducing the later use cost. This invention addresses the complex working conditions of uneven surfaces and varying soil hardness in saline-alkali lands by designing a multi-adaptive adjustment structure to ensure stable equipment operation. During movement and drilling, the cooperation between the sliding block and the fixed support rod buffers the impact of surface undulations on the drilling platform, ensuring drilling verticality. During the spraying process, spring one buffers the sliding impact of the connecting pipe, preventing interruption of the liquid supply due to changes in soil resistance. During the covering process, springs two and three adaptively adjust the thrust of the covering plate according to soil hardness, ensuring effective covering. During the compaction process, spring four enables the compaction roller to float up and down, adapting to uneven surfaces, and the tension spring automatically adjusts the gathering pressure according to the degree of soil looseness. This multi-adaptive structure design allows the equipment to adapt to different salinity levels and surface conditions without frequent parameter adjustments. Its operational stability and adaptability are significantly superior to traditional equipment, making it widely applicable to various saline-alkali land ecological restoration projects.

[0018] 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.

[0019] Example 1 like Figure 1 - Figure 14 As shown, this invention provides a technical solution: a no-till replanting machine for saline-alkali land, comprising a no-till replanting machine body 1 and a quantitative seedling delivery mechanism 3 disposed above the no-till replanting machine body 1. A perforation platform 4 is disposed on one side of the no-till replanting machine body 1. The perforation platform 4 automatically completes the actions of downward perforation and upward reset during the movement of the no-till replanting machine body 1. A seedling delivery pipe 10 is installed at an angle on the surface of the perforation platform 4. When the perforation platform 4 is moved upward and reset, the top receiving end of the seedling delivery pipe 10 is connected to the feeding end of the quantitative seedling delivery mechanism 3. The quantitative seedling delivery mechanism 3 delivers seedlings one by one into the holes perforation platform 4 through the seedling delivery pipe 10. A liquid storage tank 12 is installed on the surface of the perforation platform 4. A ring pipe 22 is disposed on the outer side of the bottom end of the seedling delivery pipe 10. Multiple nozzles 23 are installed on the surface of the ring pipe 22. When the perforation platform 4 is moved downward, the root-promoting liquid in the liquid storage tank 12 is injected into the ring pipe 22 and passes through the nozzles. The spray is applied to the rootstock of the seedlings inside the holes. A soil covering plate 28 is installed on the outer side of the bottom of the seedling delivery pipe 10. When the root-enhancing liquid is sprayed, multiple soil covering plates 28 move inward simultaneously to cover the soil around the seedlings inside the holes. Each of the multiple soil covering plates 28 is equipped with a compaction roller 54. When the soil covering plates 28 move inward, the compaction roller 54 is triggered to rotate and compact the soil around the seedlings. This integrated design of no-till reseeding, shrub seedling planting, root-enhancing liquid spraying, soil covering, and compaction solves the pain points of traditional equipment with single function and multiple operations. Through the streamlined linkage from drilling, seedling placement, liquid spraying, soil covering, to compaction, the efficiency of irrigated grass mixed sowing in saline-alkali land is greatly improved. At the same time, no-till operation protects the soil structure and avoids the aggravation of salinization caused by multiple disturbances. The seedling delivery pipe 10 is installed at an angle and the ring pipe 22 is set around the seedling delivery pipe 10 to ensure that the seedling placement, liquid spraying, and soil covering actions are accurately aligned with the hole positions, thereby improving the survival rate of seedlings.

[0020] Example 2 Improvements based on Example 1, such as... Figures 1 to 14As shown, furthermore, a U-shaped mounting frame 2 for supporting the quantitative seedling delivery mechanism 3 is installed on the surface of the no-till reseeding machine body 1. A servo motor 5 is fixedly installed on the inner wall of the U-shaped mounting frame 2. The output end of the servo motor 5 is connected to one end of a strip rod 38 set on the outer surface of the U-shaped mounting frame 2. A groove 39 is opened on the surface of the strip rod 38. A sliding connecting rod 37 is slidably connected in the groove 39. One end of the sliding connecting rod 37 is connected to the drilling platform 4. The other end of the sliding connecting rod 37 is slidably connected in the triangular groove 6 opened on the outer wall of the U-shaped mounting frame 2. A drive motor 13 is installed on the surface of the drilling platform 4. The output end of the drive motor 13 is connected to one end of a drilling drill 14 set on the bottom surface of the drilling platform 4. The output end of the drive motor 13 is connected to one end of a drilling drill 14 set on the bottom surface of the drilling platform 4. The output end of the drive motor 13 is connected to the triangular groove 6 and the strip groove 38 through the groove 6 and the groove 38. The linkage between the drilling platform 4 and the traditional no-till reseeding machine body 1 enables the drilling platform 4 to automatically complete the actions of lowering and drilling, and raising and resetting as it moves. The U-shaped mounting frame 2 provides stable support for the linkage structure of the quantitative seedling delivery mechanism 3 and the drilling platform 4, taking into account both installation strength and spatial layout rationality. The servo motor 5, through the transmission cooperation of the strip rod 38, the groove 39, and the sliding connecting rod 37, combined with the inclined guide of the triangular groove 6, realizes the automatic lowering and raising and resetting of the drilling platform 4 as it moves with the equipment, without the need for additional manual control, and is suitable for large-scale operations. The drive motor 13 directly drives the drilling drill 14, with efficient power transmission, ensuring that the drilling depth in saline-alkali land meets the standards. The linkage between the triangular groove 6 and the strip groove 9 further improves the stability and accuracy of the drilling platform 4's movements.

[0021] Furthermore, a strip groove 9 is provided on the surface of the drilling platform 4 near the U-shaped mounting bracket 2. Two sets of sliding blocks 8 are slidably connected in the strip groove 9. Fixed support rods 7 are slidably connected to the surfaces of the two sets of sliding blocks 8. The bottom ends of the fixed support rods 7 are fixedly installed on the frame of the no-till reseeding machine body 1. The sliding cooperation between the strip groove 9 and the sliding blocks 8 limits the horizontal movement trajectory of the drilling platform 4 and prevents deviation. The fixed support rods 7 are fixed to the frame of the no-till reseeding machine body 1 and provide vertical support and guidance for the sliding blocks 8, ensuring the verticality of the drilling platform 4 when it moves down and ensuring accurate drilling position. The two sets of sliding blocks 8 are symmetrically arranged to distribute the force and improve the stability of the drilling platform 4 during movement, avoiding platform shaking caused by uneven saline-alkali soil surface.

[0022] Furthermore, a storage tank 12 for storing root-promoting liquid is installed on the surface of the drilling platform 4. A discharge pipe 16 is connected to the bottom of the storage tank 12. A connecting pipe 18 is slidably connected to one end of the discharge pipe 16 extending to the bottom of the drilling platform 4. The connecting pipe 18 is connected to the annular pipe 22. A connecting groove 17 is formed inside the discharge pipe 16, and a waist groove 19 is formed on the surface of the connecting pipe 18, connecting the connecting groove 17 on the discharge pipe 16 with the waist groove 19 of the discharge pipe 16. The root-promoting liquid in the storage tank 12 is injected into the annular pipe 22 through the connecting pipe 18 and sprayed onto the seedlings in the holes through the nozzle 23. At the rootstock location, the liquid storage tank 12 is installed near the drilling platform 4, shortening the root-promoting liquid delivery path and reducing residue and waste. The sliding connection between the discharge pipe 16 and the connecting pipe 18 enables the on / off linkage of the root-promoting liquid delivery, with the liquid supply only connected when the drilling platform 4 is lowered, avoiding leakage during non-operational periods. The coordinated design of the connecting groove 17 and the waist groove 19 ensures precise docking of the liquid supply channel and stable flow. The annular pipe 22 surrounds the bottom of the seedling delivery pipe 10, and multiple nozzles 23 are evenly distributed, allowing the root-promoting liquid to fully cover the seedling roots and stems, improving absorption and thus enhancing the seedling's salt and alkali resistance and survival rate.

[0023] Furthermore, a T-shaped connecting slide rod 20 is slidably connected to the surface of the feed pipe 16 to guide and ensure the relative position of the connecting groove 17 and the waist groove 19. The other end of the T-shaped connecting slide rod 20 is fixedly installed on the outside of the connecting pipe 18. A spring 21 is sleeved on the outside of the T-shaped connecting slide rod 20 and located between the feed pipe 16 and the connecting pipe 18. The T-shaped connecting slide rod 20 connects the feed pipe 16 and the connecting pipe 18, providing precise guidance for the sliding of the connecting pipe 18, ensuring that the waist groove 19 and the connecting groove 17 are always aligned, and avoiding liquid supply interruption or leakage caused by misalignment. The spring 21 is sleeved on the outside of the T-shaped connecting slide rod 20, providing elastic restoring force when the drilling platform 4 moves up and resets, driving the connecting pipe 18 to retract, so that the waist groove 19 is disconnected from the connecting groove 17, realizing automatic stop of liquid supply, without the need for additional control mechanism, and the structure is simple and reliable.

[0024] Furthermore, a fixing plate 24 is fixedly installed on the outer side of the annular pipe 22. A fixing guide rod 26 is installed in a strip groove 25 on the surface of the fixing plate 24. A soil covering plate 28 is slidably connected to the surface of the fixing guide rod 26. A spring 27 is sleeved on the surface of the fixing guide rod 26. One end of the spring 27 abuts against the strip groove 25 on the surface of the fixing plate 24, and the other end of the spring 27 abuts against the soil covering plate 28. A connecting bracket 29 is installed at one end of the soil covering plate 28 extending out of the fixing plate 24. A fixing slide rod 30 is installed on the upper surface of the fixing plate 24. A rotating sleeve 31 is sleeved on the outer side of the fixed slide rod 30 away from the fixing plate 24. The rotating sleeve 31 is rotatably connected to the bottom surface of the drilling platform 4. A rotating slide frame 34 is rotatably connected to the outer surface of the rotating sleeve 31 near the fixed slide rod 30. An inclined rod 36 is fixed on one side of the rotating slide frame 34. The inclined rod 36 is slidably connected to... Within the inclined holes on the surface of the connecting frame 29, the inclined rod 36 at one end of the rotating slide 34 slides within the inclined groove of the connecting frame 29, causing the connecting frame 29 to move the soil covering plate 28 inward, covering the seedlings around the holes with soil. The fixing plate 24 integrates the soil covering components, optimizes the spatial layout, and improves the structural compactness. The fixing guide rod 26 and the second strip groove 25 limit the sliding direction of the soil covering plate 28, ensuring accurate coverage of the holes when moving inward. The second spring 27 provides the soil covering plate 28 with a restoring force, and it automatically returns to its original position after the operation is completed, preparing for the next soil covering. The linkage of the fixing slide rod 30, the rotating sleeve 31, the rotating slide 34, and the inclined rod 36 converts the upward movement of the fixing plate 24 into the inward movement of the soil covering plate 28, realizing the synchronous operation of spraying and soil covering, improving the continuity of the operation. The fixing guide rod 35 ensures that the rotating slide 34 moves smoothly and avoids the soil covering plate 28 from getting stuck.

[0025] Furthermore, a spring 32 is installed inside the rotating sleeve 31. One end of the spring 32 abuts against one end of the fixed slide rod 30, which is slidably connected inside the rotating sleeve 31. A fixed guide rod 35 is slidably connected to the surface of the rotating slide 34. The bottom end of the fixed guide rod 35 is connected to the fixed plate 24. The spring 32 is installed inside the rotating sleeve 31 and abuts against the fixed slide rod 30 to buffer the relative sliding impact between the fixed slide rod 30 and the rotating sleeve 31, avoiding damage to components caused by hard collisions. At the same time, it assists the fixed slide rod 30 in resetting. The fixed guide rod 35 connects the rotating slide 34 and the fixed plate 24, further limiting the movement trajectory of the rotating slide 34, ensuring the precise cooperation between the inclined rod 36 and the connecting frame 29, improving the consistency and stability of the soil covering plate 28's movement, and ensuring uniform soil covering thickness.

[0026] Furthermore, a spiral groove 33 is formed on the outer surface of the fixed slide rod 30, and a sliding protrusion 40 is slidably connected in the spiral groove 33. The sliding protrusion 40 is fixedly installed on the inner side wall of the bottom end of the rotating sleeve 31. A gear 41 is fixedly installed on the outer side of the top end of the rotating sleeve 31. A gear ring 42 meshes with the surface of the gear 41. A fixed sleeve 44 is fixedly installed on the outer side of the gear ring 42. A slider 45 is fixedly installed on the upper surface of the fixed sleeve 44. The slider 45 is slidably connected in the annular groove 15 formed on the bottom surface of the drilling platform 4. A guide rod 46 is fixedly installed in the fixed sleeve 44. A sliding frame 49 is slidably connected to the outer surface of the guide rod 46. A tension spring 47 is provided on the outer side of the guide rod 46. One end of the tension spring 47 is fixedly installed in the fixed sleeve 44, and the other end of the tension spring 47 is fixedly installed in the fixed sleeve 44. The end is connected to the sliding frame 49, and the bottom end of the sliding frame 49 is provided with a mounting slide 53. The bottom end of the mounting slide 53 is rotatably connected to the compaction roller 54. The spiral groove 33 of the fixed slide rod 30 cooperates with the sliding protrusion 40 of the rotating sleeve 31 to convert the axial movement of the fixed slide rod 30 into the rotational movement of the rotating sleeve 31. Through the meshing transmission of the gear 41 and the gear ring 42, the compaction roller 54 is driven to rotate to achieve rolling compaction. The cooperation between the slider 45 and the annular groove 15 limits the rotation trajectory of the gear ring 42 to ensure smooth transmission. The guide rod 46 provides guidance for the sliding frame 49, and the tension spring 47 provides power for the gathering action of the compaction roller 54. The mounting slide 53 realizes the flexible rotation of the compaction roller 54, adapts to the undulation of the soil surface, and improves the compaction effect.

[0027] Furthermore, a fixing sleeve 51 is fixed to one end of the sliding frame 49 near the mounting slide 53. A spring 52 is installed inside the fixing sleeve 51. One end of the spring 52 abuts against one end of the mounting slide 53, which is slidably connected inside the fixing sleeve 51. The fixing sleeve 51 and the spring 52 form an elastic buffer structure, which enables the mounting slide 53 to drive the compaction roller 54 to float up and down. This allows it to adapt to the unevenness of the saline-alkali soil surface, ensuring that the compaction roller 54 is always in contact with the soil and compacts it evenly. The buffering effect of the spring 52 prevents the compaction roller 54 from being subjected to hard impacts due to surface protrusions, protecting the components and preventing excessive compaction from damaging the seedling roots.

[0028] Furthermore, an L-shaped fixing bracket 48 is fixed to the surface of the fixing plate 24. An abutment control ring 43 is fixedly installed at one end of the fixing bracket 48. A control inclined rod 50 is fixed to the outside of the sliding frame 49. Pushing the abutment control ring 43 upward and making it fit against the surface of the control inclined rod 50, the compaction roller 54 moves closer to the center of the soil-covered area under the action of the tension spring 47. The fixing bracket 48 fixes the abutment control ring 43 and moves upward synchronously with the fixing plate 24. Through the fit between the abutment control ring 43 and the control inclined rod 50, combined with the tension of the tension spring 47, the sliding frame 49 drives the compaction roller 54 to move closer to the center of the soil-covered area, realizing a gradual compaction while rotating and gathering, ensuring close contact between the soil and the seedling roots, and avoiding soil loosening or root damage caused by excessive pressure at one time, further improving the planting survival rate.

[0029] The working principle and usage process of this invention: The equipment is based on the no-till reseeding machinery body 1 as a moving carrier. Its surface is fixed with a U-shaped mounting frame 2 to support the quantitative seedling delivery mechanism 3. When the equipment moves forward, the servo motor 5 drives the strip rod 38 to rotate, so that the sliding connecting rod 37 in the groove 39 on the surface of the strip rod 38 moves synchronously. One end of the sliding connecting rod 37 slides along the triangular groove 6 on the outside of the U-shaped mounting bracket 2, and the other end drives the drilling platform 4 to slide horizontally along the fixed support rod 7 in the strip groove 9. With the help of the inclined guide of the triangular groove 6, the drilling platform 4 automatically completes the horizontal and downward movement with the movement of the equipment. At this time, the drive motor 13 drives the drilling drill 14 to rotate to complete the drilling operation of the saline-alkali land. After the drilling is completed, the sliding connecting rod 37 moves upward along the triangular groove 6, driving the drilling platform 4 to reset, realizing the cycle of upward movement and reset. When the drilling platform 4 moves up and resets, the top receiving end of the seedling delivery pipe 10 installed on its surface is precisely connected to the feeding end of the quantitative seedling delivery mechanism 3. The quantitative seedling delivery mechanism 3 delivers a single shrub seedling through the seedling delivery pipe 10 into the hole drilled by the drilling platform 4, thus completing the precise placement of the seedling. The liquid storage tank 12 on the surface of the drilling platform 4 stores root-strengthening liquid, and its bottom is connected to the connecting pipe 18 through the discharge pipe 16: When the drilling platform 4 moves down, the annular pipe 22 is subjected to the resistance pressure of the soil, which causes the connecting pipe 18 connected to it to slide into the feed pipe 16. The T-shaped connecting slide bar 20 on the outside of the connecting pipe 18 slides along the preset trajectory of the feed pipe 16, which plays a guiding role and ensures that the waist groove 19 on the surface of the connecting pipe 18 is precisely aligned and connected with the connecting groove 17 on the feed pipe 16. The root-promoting liquid in the storage tank 12 flows into the connecting pipe 18 through the connecting groove 17 and waist groove 19, and then into the ring pipe 22. Finally, it is sprayed into the root and stem position of the seedling in the hole through multiple nozzles 23 on the surface of the ring pipe 22, thereby improving the survival rate of the seedling. The spring 21 sleeved on the outside of the T-shaped connecting slide bar 20 provides elastic restoring force when the drilling platform 4 moves up and resets, driving the connecting pipe 18 back, so that the waist groove 19 is disconnected from the connecting groove 17, and the cycle of spraying action is completed. A soil-covering plate 28 is mounted on the surface of the fixing plate 24 on the outer side of the annular pipe 22 via a fixing guide rod 26. A spring 27 is sleeved on the outer side of the fixing guide rod 26 to provide a restoring force. When the annular pipe 22 is subjected to the resistance pressure of the soil, as the pressure continues, the position of the fixed plate 24 moves upward relative to the drilling platform 4, causing the rotating slide 34 to slide along the fixed guide rod 35; The inclined rod 36 on one side of the rotating slide 34 is embedded in the inclined groove of the connecting frame 29 at the rear end of the soil covering plate 28. Through the linkage of the inclined surfaces, the connecting frame 29 drives the soil covering plate 28 to move inward along the fixed guide rod 26, guiding the soil around the hole to cover the roots of the seedling, thus completing the soil covering action. After the backfilling is completed, the equipment simultaneously starts the compaction process: The spiral groove 33 on the outer surface of the fixed slide rod 30 cooperates with the sliding protrusion 40 on the inner side of the rotating sleeve 31. When the fixed slide rod 30 moves upward with the fixed plate 24, the sliding protrusion 40 slides along the spiral groove 33, driving the rotating sleeve 31 to rotate. The gear 41 on the outer side of the top of the rotating sleeve 31 meshes with the gear ring 42, driving the gear ring 42 to rotate along the annular groove 15 on the bottom surface of the drilling platform 4. The fixing sleeve 44 on the outside of the gear ring 42 drives the guide rod 46 to rotate synchronously. The sliding frame 49 on the guide rod 46 rotates with the gear ring 42. The fixing bracket 48 on the surface of the fixing plate 24 pushes the abutment control ring 43 to move upward relative to it, and it fits against the control inclined rod 50 on the outside of the sliding frame 49. Under the tension of the tension spring 47, the sliding frame 49 slides along the guide rod 46, causing the compaction roller 54 at the bottom of the mounting slide 53 to move closer to the center of the soil-covered area. The compaction roller 54 rotates under the meshing transmission of gear 41 and gear ring 42, and under the cooperation of the contact control ring 43 and control inclined rod 50 and the tension of tension spring 47, it slowly moves towards the center of the soil-covered area, realizing a gradual compaction operation of rotating and gathering at the same time, ensuring that the soil and seedling roots are in close contact. The spring 52 inside the fixed sleeve 51 provides a buffer for the compaction roller 54, so that the compaction roller 54 can adaptively adjust the pressure according to the soil hardness. At the same time, the compaction roller 54 rotates with the toothed ring 42 to uniformly compact the covered soil and ensure that the seedling roots are in close contact with the soil. After completing drilling, seedling placement, liquid spraying, soil covering, and compaction, the drilling platform 4 automatically moves upward and resets with the equipment, and the quantitative seedling delivery mechanism 3 prepares for the placement of the next seedling. The equipment continues to move forward to realize continuous irrigation, grassing, no-till replanting, and hole planting operations.
