Description

Technical Field

[0001] The invention relates to the technical field of soil improvement, in particular to an ecological garden soil improvement method. Background Art

[0002] With the acceleration of urbanization, the importance of urban landscaping has become increasingly prominent. Ecological gardens, as a kind of urban green space that combines beauty, ecology and functionality, can not only beautify the environment and improve air quality, but also regulate urban microclimate and reduce urban heat island effect. However, due to the long-term influence of human activities on urban soil, there are often problems such as tight structure, poor nutrients and low organic matter content, which leads to poor plant growth and makes it difficult for the functions and effects of ecological gardens to be fully exerted.

[0003] Chinese patent (Announcement No.: CN115633558A), the scheme specifically relates to the field of soil improvement, and specifically includes the following steps: S1, determination of soil properties; S2, placement and inoculation of earthworm bait; S3, inoculation of strains; S4, simultaneous inoculation of earthworms and strains; S5, data statistics, formulation of soil improvement scheme, the present invention inoculates the soil with different strains and earthworms, then sequentially tests the soil, and formulates the best soil improvement scheme based on the statistics and analysis of the test data. This scheme can formulate a soil improvement plan more accurately and specifically according to the results of actual data, thereby ensuring the improvement of the soil environment, improving the soil properties, and increasing the survival rate of seedlings, thereby reducing the replanting and replacement of seedlings during the warranty and maintenance period, and reducing the economic investment of landscaping construction units.

[0004] Chinese patent (Announcement No.: CN118176872A), the scheme includes a bracket, a soil turning and crushing structure that can work synchronously, a soil turning and flattening structure, and an improver spraying structure installed on the bracket and cooperating with the soil turning and flattening structure to improve the soil. The steps of improving the soil using the above-mentioned soil improvement device are: S1, crushing and turning the garden soil through the soil turning and crushing structure; S2, turning and flattening the crushed soil through the soil turning and flattening structure; S3, completing the soil improvement work through the improver spraying structure. The present invention avoids the tediousness of the prior art of transporting, crushing, mixing and improving the soil and then transporting it to the land, and realizes the crushing, turning and improving of the soil in the soil, thereby improving the effect of soil improvement.

[0005] The existing garden soil improvement device needs to bury the improvers such as organic fertilizer, microbial fertilizer or organic fertilizer in the soil when in use, so it is necessary to dig a gully of a certain depth in the garden soil. For example, patent No. CN118176872A uses L-shaped crushing teeth to crush the soil, but the horizontal height of the vehicle body will not change. The low horizontal height of the L-shaped crushing teeth will affect the movement of the vehicle body. If the horizontal height of the L-shaped crushing teeth is high, the soil cannot be crushed.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 10 The present invention provides a technical solution: an ecological garden soil improvement method, comprising the following steps: S1. Improved evaluation: S11. Soil assessment: Assess the current status of garden soil, including soil pH, nutrient content, organic matter content and structural characteristics; S12. Determine improvement goals: Based on the results of soil assessment, the needs of plant species and the requirements of garden design, determine the specific goals of soil improvement, including improving soil fertility, improving soil structure or adjusting soil pH; S13. Selection of improvement materials: According to the improvement objectives, select appropriate improvement materials, including compost, humus or green manure for increasing organic matter, and lime or sulfur for adjusting pH value; S2. Adding improved materials: According to the use method of the selected improved materials, the improved materials are applied to the garden soil through the mobile vehicle, including spraying, mixing and burying; S3. Monitoring and maintenance: After applying the improvement materials, regularly monitor the garden soil status, including pH value, nutrient content and plant growth, and make necessary adjustments and further improvements based on the monitoring results to ensure continuous improvement of soil quality. Implement long-term soil management measures, such as regular application of organic fertilizers, maintaining appropriate soil moisture and mulch management.

[0023] like Figure 1 As shown, first conduct a comprehensive assessment of the soil, analyze the soil's pH value, nutrients, organic matter content and structural characteristics, understand the soil's current status and existing problems, and then determine specific improvement goals based on the assessment results and the needs of plant species and the requirements of garden design. These goals may include improving soil fertility, improving soil structure or adjusting soil pH to ensure the pertinence and effectiveness of the improvement method. According to the improvement goals, choose compost, humus or green manure to increase organic matter, or lime or sulfur to adjust pH to ensure the scientificity and effectiveness of the materials.

[0024] According to the usage of the selected improvement materials, the improver materials are applied to the garden soil through a mobile vehicle. This process includes spraying, mixing and burying, which ensures the effective use of the improvement materials and the comprehensive improvement of the soil. In the burying method, trenches are dug in the soil, and the improvement materials are filled into the trenches, and finally the trenches are filled to ensure that the improver can be buried to a certain depth in the soil.

[0025] After applying the improvement materials, regular monitoring of the garden soil status is an important link to ensure the continued improvement effect. By monitoring the soil pH, nutrients and plant growth, we can understand the soil improvement effect and make necessary adjustments and further improvements based on the monitoring results. In this process, implementing long-term soil management measures, such as regular application of organic fertilizers, maintaining appropriate soil moisture and mulch management, will help maintain the soil in good condition, promote the healthy growth of plants and the sustainable development of ecological gardens.

[0026] Furthermore, the ecological garden soil improvement method comprises a storage box 2 for containing improvement materials arranged on a mobile vehicle body, and the mobile vehicle body is provided with a flat burying structure for burying the improvement materials into the garden soil; The horizontal buried structure comprises a base 1 fixedly connected to the mobile vehicle body, a horizontal slide 4 freely movable in the horizontal direction is provided on the base 1, and a horizontal slide groove 6 for the horizontal movement of the horizontal slide 4 is provided on the base 1, and a digging assembly for digging trenches on the soil is provided on the horizontal slide 4; The digging assembly includes a vertical positioning rod 5 that moves horizontally synchronously with the horizontal slide 4 and changes its horizontal height, and a triangular soil-breaking cone 3 for shoveling soil is fixedly connected to the bottom of the vertical positioning rod 5; The transverse slide 4 is fixedly connected with a material transfer frame 31 for receiving the improved material in the storage box 2, and the base 1 is provided with a feeding component for feeding the improved material in the material transfer frame 31 into the excavated gully; The base 1 is also provided with a leveling component for filling the dug gully after the improved material is put into the gully.

[0027] like Figure 2 and Figure 3 As shown, when improving the garden soil, the improved material is placed in the storage box 2, and the storage box 2 is moved to the position of the soil to be improved by the mobile vehicle body. At the same time, the triangular soil-breaking cone 3 is driven by the digging component to dig a gully of a certain depth in the garden soil, and during the gully excavation process, a certain amount of improved material is put into the excavated gully through the feeding component. At the same time, after the improved material is put into the gully, under the action of the leveling component, the soil cut out during the gully excavation can be buried in the gully to ensure the flatness and beauty of the soil surface, and to avoid the improved material from being exposed to the air, reduce material loss, protect the plant root system, promote healthy growth, and the leveled soil structure is more stable, which is conducive to the effective absorption and action of the improved material, thereby improving the overall effect of soil improvement.

[0028] In one of the more preferred embodiments, the digging assembly further comprises an electric push rod fixedly connected to the base 1, and the telescopic end of the electric push rod is fixedly connected to the transverse slide 4; The vertical positioning rod 5 vertically slides through the horizontal slide seat 4, and the horizontal slide seat 4 has a guide seat 7 that is fixedly rotated on one end away from the triangular earth-breaking cone 3. A twisting ball seat 9 is arranged in the guide seat 7, and a ball cavity is opened for the twisting ball seat 9 to rotate. The base 1 is provided with a guide column 8 which can freely move in the vertical direction. The torsion ball seat 9 is slidably sleeved on the guide column 8. The guide column 8 includes an integrally formed horizontal guide portion 801 and an oblique guide portion 802.

[0029] The end of the oblique guide portion 802 away from the horizontal guide portion 801 is fixedly connected to a positioning block 10, a longitudinal sliding frame 12 is fixedly connected to the base 1, and the longitudinal sliding frame 12 is provided with a groove for sliding the longitudinal sliding frame 12, a side ear plate 11 is fixedly connected to the side wall of the positioning block 10, the side ear plate 11 is provided with threaded holes, and the longitudinal sliding frame 12 is provided with a plurality of positioning holes 13 corresponding to the threaded holes.

[0030] like Figure 2 , Figure 3 , Figure 5 and Figure 8 As shown, the vertical positioning rod 5 slides through the transverse slide 4. Therefore, when the electric push rod drives the transverse slide 4 to move horizontally on the base 1, it can drive the vertical positioning rod 5 to move horizontally synchronously. The guide seat 7 arranged at the end of the vertical positioning rod 5 can move along the laying direction of the guide column 8. The transverse slide 4 is initially located at one end close to the longitudinal slide frame 12. With the horizontal movement of the transverse slide 4, the torsion ball seat 9 arranged on the guide seat 7 slides at the oblique guide portion 802. At this time, the horizontal height of the vertical positioning rod 5 will change.

[0031] At the same time, as the transverse slide 4 continues to move in the horizontal direction, the guide seat 7 corresponds to the position of the horizontal guide portion 801. At this time, when the transverse slide 4 moves in the horizontal direction subsequently, the torsion ball seat 9 in its guide seat 7 slides at the horizontal guide portion 801. Therefore, the horizontal height of the guide seat 7 and the vertical positioning rod 5 no longer changes.

[0032] Therefore, in actual use, the triangular ground-breaking cone 3 fixed at the bottom of the vertical positioning rod 5 will not contact the soil in the initial state, but will be suspended on the upper surface of the soil. As the transverse slide 4 moves in the horizontal direction, the triangular ground-breaking cone 3 tilts into the soil until it is inserted into the soil to a certain depth. Subsequently, as the transverse slide 4 moves horizontally, the triangular ground-breaking cone 3 moves horizontally synchronously and digs trenches in the soil to provide space for the investment of improved materials.

[0033] It should be noted that when different improved materials are used, their buried depths in the soil are different. Therefore, in actual use, according to the selected improved material, the relative position of the positioning block 10 on the longitudinal sliding frame 12 can be changed, and the bolts can be passed through the threaded holes and the corresponding positioning holes 13 in turn, so as to adjust the horizontal height of the positioning block 10, thereby changing the initial height of the triangular breaking cone 3, so that under the operation of the digging assembly, trenches of different depths can be excavated in the soil to meet the buried depths of different improved materials.

[0034] Based on the embodiment of the digging assembly, the feeding assembly includes a material guide plate 35 fixedly connected to the base 1, and a step plate 34 is fixedly connected to the material guide plate 35, and the step plate 34 includes an integrally formed upper step portion 341 and a lower step portion 342; The material moving frame 31 corresponds to the position of the material discharge opening of the material storage box 2 in the vertical direction, and a transverse sealing plate 32 for sealing the material discharge opening of the material storage box 2 is fixedly connected to the material moving frame 31; A bottom plate 33 is provided at the lower opening of the material transfer frame 31 so as to rotate on a fixed axis. The bottom plate 33 is in sliding contact with the upper surface of the step plate 34 .

[0035] like Figure 2 , Figure 3 and Fig.10 As shown, when the transverse slide 4 is in the initial state, it corresponds to the position of the unloading port of the material moving frame 31, and the upper opening end of the material moving frame 31 is consistent with the size of the unloading port of the material storage box 2. As the transverse slide 4 moves horizontally, the material moving frame 31 moves synchronously with the transverse slide 4. Among them, when the transverse sealing plate 32 is separated from the unloading port position of the material moving frame 31, the transverse sealing plate 32 blocks the unloading port of the material moving frame 31.

[0036] At the same time, the bottom plate 33 set at the bottom of the material moving frame 31 is in a horizontal state in the initial state and blocks the lower opening of the material moving frame 31, that is, in the initial state, the bottom plate 33 corresponds to the position of the upper step 341, and, due to the obstruction of the upper step 341, the bottom plate 33 cannot be deflected in the vertical direction.

[0037] At the same time, as the transverse slide 4 and the material transfer frame 31 continue to move, the bottom plate 33 corresponds to the position of the lower step 342. At this time, the bottom plate 33 naturally deflects under the action of gravity, thereby causing the modified material in the material transfer frame 31 to fall into the excavated ditch below.

[0038] It should be noted that, in actual use, an inclined baffle can be provided below the guide plate 35 to ensure that the improved material in the material moving frame 31 falls toward the position of the excavated gully, and when the gully excavation is completed and the material moving frame 31 and the transverse slide 4 are driven to return to their initial positions, the triangular earth-breaking cone 3 will move in the gully, but since the gully has a certain depth, the improved material will not be pushed out of the gully by the triangular earth-breaking cone 3.

[0039] Based on the feeding assembly embodiment, the leveling assembly includes two groups of Z-shaped racks 17 that can move toward or away from each other in the horizontal direction, and the two groups of Z-shaped racks 17 are provided with a unidirectionally rotating ratchet 21 on the side facing the base 1, and the ratchet 21 rotates on the base 1 with a fixed axis, and the ratchet 21 is provided with a leveling plate 28 that moves in a triangular trajectory in the vertical direction and is used to push the soil; The transverse slide 4 is fixedly connected with a threaded rod 14, and the base 1 is provided with an internal threaded cylinder 15 which is threadably matched with the threaded rod 14, and a central gear 16 is fixedly sleeved on the outer circumference of the internal threaded cylinder 15. The central gear 16 is meshedly connected with two sets of Z-shaped racks 17, and the two sets of Z-shaped racks 17 are arranged opposite to each other.

[0040] The base 1 is provided with two grooves for the Z-shaped rack 17 to slide horizontally, the Z-shaped rack 17 is meshedly connected with a co-directional gear 18, and the co-directional gear 18 rotates on the base 1 with a fixed axis, and the co-directional gear 18 is provided with multiple groups of yielding grooves 19, and the yielding grooves 19 are provided with ratchets 20 that rotate on the co-directional gear 18 with a fixed axis, and the ratchet 21 is meshedly connected with the ratchet pawl 20.

[0041] like Figure 2 , Figure 6 , Figure 7 and Fig. 9 As shown, when the threaded rod 14 moves in the horizontal direction, it can drive the threaded rod 14 fixed thereon to move horizontally synchronously. The threaded rod 14 is threadedly connected to the internal threaded tube 15. Therefore, the horizontal movement of the threaded rod 14 can drive the internal threaded tube 15 and the central gear 16 mounted thereon to rotate in the vertical direction.

[0042] Among them, when the central gear 16 rotates, it can drive the two sets of Z-shaped racks 17 arranged opposite to each other to move synchronously toward or away from each other in the horizontal direction. When the threaded rod 14 moves toward the direction of the internal threaded tube 15 to drive the triangular breaking cone 3 to excavate the garden soil, the Z-shaped rack 17 drives the ratchet 21 meshing with it to rotate in the opposite direction. Since a torsion spring is provided between the ratchet pawl 20 and the same-direction gear 18 to drive the ratchet pawl 20 to return to its initial position, the torsion spring is an existing device and a technical means well known to those skilled in the art, so it is not shown in the figure.

[0043] Therefore, when the co-directional gear 18 reverses, the ratchet wheel 21 is not driven to rotate through the pawl 20, and in the initial state, the leveling plate 28 is at a certain height from the soil surface, and thus the position of the leveling plate 28 does not change during the process of the triangular breaking cone 3 excavating the gully.

[0044] At the same time, when the transverse slide 4 drives the threaded rod 14 to move horizontally away from the internal threaded tube 15, the central gear 16 drives the Z-shaped rack 17 to move horizontally and drives the co-directional gear 18 to rotate forward. At this time, the co-directional gear 18 drives the ratchet 21 to rotate synchronously with it through the pawl 20 during the rotation process, thereby driving the leveling plate 28 to rotate one circle along a triangular trajectory, that is, the leveling plate 28 first moves downward in an inclined manner, and then moves horizontally in the direction of the excavated gully after reaching the lowest horizontal position, and finally moves in an inclined manner at the end position of the horizontal operation and returns to the initial position.

[0045] Furthermore, a swing rod 22 is coaxially fixed on the ratchet 21, and a side gear 23 is fixedly rotated on one end of the swing rod 22 away from the ratchet 21, and the side gear 23 is meshedly connected with an inner gear ring 24, and the inner gear ring 24 is fixedly connected to the base 1; A vertical limit rod 25 is fixedly rotated on the side gear 23, and a receiving groove is provided on the vertical limit rod 25. A blocking rod 27 is slidably connected in the receiving groove and a return spring 26 is provided. Both ends of the return spring 26 are fixedly connected to the vertical limit rod 25 and the blocking rod 27. One end of the blocking rod 27 away from the vertical limit rod 25 is fixedly connected to the leveling plate 28. A rectangular plate 30 is fixedly connected to the inner gear ring 24 , and a limit block 29 is provided on the rectangular plate 30 for the vertical limit rod 25 to slide vertically, and a rectangular groove is opened on the rectangular plate 30 for the limit block 29 to slide horizontally.

[0046] like Figure 2 , Figure 3 and Figure 6 As shown, when the blocking rod 27 rotates in the vertical direction, it can drive the rocker arm 22 coaxially arranged thereon to rotate synchronously, and the rocker arm 22 is meshingly connected with the inner gear ring 24. Therefore, when the side gear 23 revolves around the ratchet wheel 21, it can rotate synchronously.

[0047] At the same time, a vertical limit rod 25 is provided on the side gear 23, and the vertical limit rod 25 is slidably set on the limit block 29, and the limit block 29 can only move in the horizontal direction under the restriction of the rectangular groove. Therefore, under the restriction of the limit block 29, the orientation of the vertical limit rod 25 is always vertical, and the side gear 23 will change the horizontal position of the vertical limit rod 25 when it revolves. However, the rotation process of the side gear 23 will synchronously change the horizontal position of the vertical limit rod 25, and the rotation process of the side gear 23 will compensate for the horizontal displacement caused by the revolution of the side gear 23. Therefore, when the vertical limit rod 25 is in the lowest horizontal position, it can move linearly in the horizontal direction.

[0048] It should be noted that, since the surface of garden soil is usually irregular, a return spring 26 is provided between the blocking rod 27 and the vertical limit rod 25 to avoid obstacles such as stones. When the vertical limit rod 25 moves horizontally, the leveling plate 28 on the blocking rod 27 is driven to move along the soil surface, thereby refilling the soil accumulated when digging the ditch into the ditch, so as to make the soil surface smooth and beautiful, avoid exposing the improved material to the air, and avoid material loss.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
