Description

Technical Field

[0001] The invention relates to a machine for improving cultivated land soil, and in particular to a soil improving device. Background Art

[0002] In order to give full play to the fertilization and carbon sequestration benefits of enhanced silicate rock weathering, the silicate rock powder needs to be fully mixed with the soil when applied in cultivated land ecosystems to promote the chemical reaction between silicate and carbonic acid (CO2+H2O) in the soil to generate bicarbonate (HCO 3- ) and base cations (K + , Ca 2+ etc.), thereby increasing soil fertility while reducing CO2 in the atmosphere / soil 2 It dissolves in water bodies in the form of dissolved inorganic carbon (DIC) and is eventually transported to the ocean via surface runoff for long-term storage.

[0003] Currently, some large farms abroad primarily excavate soil, thoroughly mix it with silicate rock powder using a mixing truck (or a tiller), and then evenly spread it across the field, achieving good soil improvement results. However, this approach is only suitable for flat arable land and requires high machinery and equipment costs (often exceeding one million yuan per unit). It is also inefficient (it involves first extracting soil, then mixing it, and then backfilling it). In many areas of China, soil improvement methods rely on manual spreading and tilling (which involves spreading silicate rock powder and then repeatedly tilling the soil). This is not only time-consuming and labor-intensive, but also inefficient and cannot guarantee the tillage depth and improvement effect. In particular, it is difficult to ensure that the silicate rock powder is evenly distributed within the soil at the target depth (including the depth range of 2 to 30 cm from the surface). Furthermore, biochar, due to its porous structure and excellent adsorption and carbon sequestration capabilities, is widely used in soil improvement. However, biochar-based soil improvement methods also require thorough mixing of the soil and biochar powder. Summary of the Invention

[0004] At least in order to solve the problems mentioned in the background technology, the present invention provides a soil improvement device, and the specific solution is as follows.

[0005] A soil improvement device comprises a ridger. A powder applying mechanism is arranged at the tail of the ridger. The powder applying mechanism is used to spread a soil improver in the soil of a ridge, so that the soil improver is mixed into soil particles.

[0006] As a preferred solution, the discharge hole of the powder application mechanism can be located in the soil ridge and at a depth of 2 to 30 cm from the ground surface.

[0008] In order to more smoothly mix the soil improvement powder into the target depth interval in the soil, a taut steel wire is arranged inside the thin steel tube, and the steel wire is connected to the cantilevered rods.

[0009] As a preferred solution, the end of the cantilevered rod is fixedly connected to a diagonal rod, a plurality of thin steel tubes and steel wires are arranged at intervals on the diagonal rod, the height difference between adjacent thin steel tubes is 8-15 mm, and the height difference between adjacent steel wires is also 8-15 mm.

[0012] As a preferred solution, two or three sets of powder distribution mechanisms are arranged side by side on the ridger.

[0013] Further, one end of the thin steel tube and the steel wire is respectively provided with a tension bolt for adjusting the tautness thereof.

[0016] S2, controlling the compressed air supply system and the soil conditioner supply mechanism to be turned on, so that the soil conditioner is sprayed into the soil of the soil ridge during the ridging.

[0017] Beneficial effects: The soil improvement equipment in the application has simple structure, low manufacturing and maintenance costs, and only needs to be matched with corresponding powder distribution mechanisms on a conventional ridger. It is not only suitable for soil improvement on flat farmland, but also suitable for soil improvement on sloping land, and can smoothly and efficiently improve the soil, save the amount of soil improvement powder, and more importantly, uniformly distribute the soil improvement powder in the soil during the process of plowing and ridging.

[0024] The technical solutions of the application will be described in detail below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the application, not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the application.

[0025] Example 1: Please refer to Figures 1 to 5 , a soil improvement equipment, comprising a ridger, two sets of powder distribution mechanisms arranged side by side are arranged at the tail of the ridger, and the powder distribution mechanisms are used to distribute soil improvement agent (silicate rock powder) in the soil of the soil ridge, so that the soil improvement agent is mixed into the soil particles.

[0026] In this embodiment, the powder application mechanism includes two cantilever arms 2 mounted parallel to a frame 1. The ends of the cantilever arms 2 are fixedly connected to an inclined rod 6, the height of which is substantially equal to the depth of the ridge furrow. The ends of the two cantilever arms 2 are located behind the ridging baffle 3. A taut, thin steel tube 5, perpendicular to the cantilever arms 2, is connected to the cantilever arms 2 at both ends. The thin steel tube 5 has a plurality of spray holes 9 arranged at intervals. The thin steel tube 5 is connected to an external compressed air supply system through a feed pipe 7. The feed pipe 7 is also connected to a soil conditioner supply mechanism. Both the soil conditioner supply mechanism and the compressed air supply system are mounted on the ridging machine. When the soil conditioner supply mechanism and the compressed air supply system are simultaneously activated, a high-pressure, high-speed fluid composed of soil conditioner particles and compressed air is dispersed into the soil through the spray holes 9 in the thin steel tube 5. A taut steel wire 4 is provided inside the thin steel tube 5, which is connected to the cantilever arms 2. The diameter of the steel wire 4 is 2 mm, the aperture of the thin steel tube 5 is 4 mm and the outer diameter is 8 mm, and the aperture of the spray hole 9 is 2 mm.

[0027] In this embodiment, one end of the thin steel tube 5 and the steel wire 4 are respectively fixedly connected to the inclined rod 6, and the other ends of the thin steel tube 5 and the steel wire 4 are connected to the inclined rod 6 by tension bolts. The tension of the steel wire 4 can be adjusted by means of the tension bolts. Among them, one tension bolt 8 is fixedly connected to the steel wire 4 and is threadedly engaged with the mounting hole on the inclined rod 6; the outer wall of the thin steel tube 5 near the inclined rod 6 is provided with a thread 12, and another tension bolt 13 is engaged with the thread 12 and is located on the outer wall of the inclined rod 6 (such as Figure 4 As shown), the tensioning bolt 8 is also used to adjust the tightness of the thin steel tube 5.

[0028] In this embodiment, four thin steel tubes 5 and four steel wires 4 are arranged at intervals on the diagonal rod 6. The height difference between adjacent thin steel tubes 5 is 20 mm, and the height difference between adjacent steel wires 4 is also 20 mm. The total height interval covered by the corresponding four thin steel tubes 5 is 60 mm. During the ridge forming process, the height of the topmost thin steel tube 5 from the ground surface is controlled to 50 mm, so the discharge hole will be located in the soil ridge and at a depth range of 5 to 11 cm from the ground surface.

[0029] In this embodiment, the compressed air supply system, the soil conditioner supply mechanism, and the ridging machine are all connected to a controller. The memory of the controller stores a program that can be run on a processor. When the processor executes the program, the following steps / functions are implemented:

[0030] S1, control the ridging machine to move along the preset path and implement ridging;

[0031] S2, control the compressed air supply system and soil conditioner supply mechanism to start, combined with Figure 5As shown, the silicate rock powder entering the feed pipe 10 of the soil conditioner supply mechanism mixes with the high-pressure high-speed air (compressed air) in the pipe 7 and continues to flow along the pipe 7, enters the inner cavity of the thin steel pipe 5, and is finally sprayed out through the spray holes 9 on the thin steel pipe 5, so as to spread the silicate rock powder in the soil of the soil ridge during the ridging process.

[0032] During the ridging process, the ridging baffle 3 is always located at the ridge ditch on both sides of the soil ridge, the lower end of the inclined rod 6 is higher than the lowest point of the ridge ditch, and as the ridger moves forward, the powder spreading mechanism also moves forward synchronously (as shown by the arrow in the figure), and the steel wire 4 moves forward in the soil ridge in a way similar to cutting something horizontally with a steel wire, which is linear cutting and loosening the soil, so as to loosen the soil without turning and throwing. Figure 6 As shown, the arrow in the figure indicates the forward direction), and the thin steel pipe 5 continues to move forward behind the steel wire 4 and uniformly spreads the high-pressure high-speed fluid composed of the soil conditioner powder and compressed air through the spray holes 9 on the thin steel pipe 5 into the soil.

[0033] In this embodiment, the cooperation of the steel wire 4 and the thin steel pipe 5 in the tightened state is very critical, and the cleverness lies in first cutting the loosened soil by means of the steel wire 4 to facilitate the smooth following of the thin steel pipe 5, and then smoothly spraying the silicate rock powder and compressed air into the soil through the spray holes 9 on the thin steel pipe 5, and the compressed air in the process further penetrates into the soil and diffuses, so as to one-time introduce the silicate rock powder around the thin steel pipe 5 into the soil, which saves the heavy process of turning and throwing the soil in the traditional way. Due to the arrangement of multiple rows of steel wires 4 and thin steel pipes 5 at different heights, the silicate rock powder can be one-time spread in the target depth interval of the soil as needed.

[0034] Taking the soil improvement equipment in this embodiment as an example, if the silicate rock powder needs to be spread in the soil ridge and at a depth interval of 5-11 cm from the ground surface, it can be completed during the ridging process, which is very efficient. It only takes half an hour to complete the soil improvement of one mu of farmland, and the soil improvement depth interval can be accurately locked, and there is no loss of silicate rock powder exposed on the ground surface. Using the traditional method (spreading silicate rock powder by manpower and then using a plow to plow multiple times), it takes at least one day to complete, and the plowing depth determines the depth interval of the silicate rock powder, which cannot accurately adjust the soil improvement depth.

[0035] The soil improvement equipment in this scheme has a simple structure and low manufacturing and maintenance costs. It only needs to be equipped with a corresponding powder spreading mechanism on a conventional ridging machine. It is not only suitable for soil improvement on flat cultivated land, but also suitable for soil improvement on sloping land. It can also improve the soil smoothly and efficiently. More importantly, in the process of ridging the cultivated land, the uniform spreading of silicate rock powder is simultaneously achieved, and the silicate rock powder can be quickly spread to the target depth range in the soil at one time. It has the advantages of simple and easy operation and high efficiency. It can also flexibly adjust the spreading depth and density of silicate rock powder, which significantly optimizes the soil improvement effect.

[0036] Example 2: A soil improvement device, referring to Example 1, differs from Example 1 in that the number and height of the steel wires 4 and the thin steel tubes 5 are determined by those skilled in the art as needed.

[0037] The soil improvement equipment in this solution is suitable not only for improving soils previously planted with dryland crops, but also for improving soils with high water content (such as clay or soil previously planted with rice). The soil improvement process is less affected by the soil's moisture content. Traditional methods (whether using a blender or a tiller) make it difficult to smoothly and evenly distribute silicate rock powder in soils with high moisture content, unless the moisture in the soil is dried out and granulated before mixing.
