Description

Technical Field

[0001] The present invention relates to the technical field of soil improvement, and in particular to a soil structure improvement device and a use method thereof. Background Art

[0002] Soil improvement refers to a series of technical measures that utilize theories and techniques from multiple disciplines, including soil science, biology, and ecology, to eliminate or prevent adverse factors that affect crop growth and cause soil degradation, thereby improving soil properties, enhancing soil fertility, and creating favorable soil environmental conditions for crops. Basic measures include: ① Soil water improvement, such as establishing farmland irrigation and drainage projects to regulate groundwater levels, improve soil moisture conditions, and eliminate and prevent swamping and salinization; ② Soil engineering improvement, such as using engineering measures like land leveling, terrace construction, and flood diversion to improve soil conditions; ③ Soil biological improvement, using various biological approaches (such as planting green manures) to increase soil organic matter and enhance soil fertility, or establishing shelterbelts to prevent soil erosion; ④ Soil tillage improvement, improving soil conditions through improved farming methods; and ⑤ Soil chemical improvement, such as applying chemical fertilizers and various soil conditioners to increase soil fertility, improve soil structure, and eliminate soil pollution.

[0003] Chemical soil amendment involves using chemical agents to change the acidity or alkalinity of the soil. Commonly used chemical amendments include lime, gypsum, phosphogypsum, calcium chloride, ferrous sulfate, and calcium humate, depending on the soil's properties. For example, alkaline soils require the application of gypsum, phosphogypsum, and other agents to exchange calcium ions for sodium ions on the surface of the soil colloids, lowering the soil's pH. Acidic soils require the application of calcareous substances. Chemical amendment must be combined with water conservancy and agricultural measures to achieve optimal results.

[0004] In the prior art, when spraying soil conditioners, the spraying methods generally used are flood irrigation, furrow irrigation, drip irrigation, sprinkler irrigation or mobile spraying. However, no matter which of the above methods is adopted, the conditioner gradually penetrates from the soil surface to the deep soil. If the spraying amount is too small, the conditioner cannot penetrate deep into the soil, and the improvement effect is poor. If the conditioner is sprayed deep into the soil by spraying at a high flow rate for a long time, it is easy to overspray, which not only causes waste of conditioner, but also leads to imbalance of soil microbial community, affects the natural fertility cycle of the soil, and destroys the ecological balance. If the chemical components in the soil conditioner are not fully degraded, they may seep into the groundwater system with rainwater or irrigation water, posing a potential threat to water quality and affecting the drinking water safety of humans, animals and plants.

[0029] like Figures 1 to 8 As shown, a soil structure improvement device comprises:

[0030] Vehicle 1, which is a common agricultural vehicle or human-powered cart;

[0031] The lifting mechanism includes: a transmission box 3, which is arranged on the carrier 1; a turntable 4, which is rotatably connected to the inner side of the transmission box 3; a driving pin 5, which is adjustably arranged on the turntable 4; a vertical rod 6, which is vertically slidably connected to the carrier 1; a rectangular groove 28, which is arranged at the upper end of the vertical rod 6, and the driving pin 5 is adapted to the rectangular groove 28; a driving unit 18, which is a reduction motor, and a driving unit 29 is arranged on the transmission box 3, and the output end of the driving unit 29 is fixedly connected to the turntable 4;

[0032] The spraying mechanism includes: a container 2, which is arranged on the carrier 1 and is used to hold the improver; a liquid separating box 7, which is a hollow disc-shaped structure and is arranged at the lower end of the vertical rod 6; a plurality of spraying rods 8, which are hollow tubular structures and are connected to the interior of the liquid separating box 7; a liquid outlet 9, which is arranged at the lower part of each spraying rod 8; a hose 11, which is connected to the liquid outlet 9; a booster pump 10, the water inlet end of the booster pump 10 is connected to the container 2, and the water outlet end of the booster pump 10 is connected to the liquid separating box 7 through the hose 11.

[0033] During specific use, as the carrier 1 moves, the driving part 29 drives the turntable 4 to rotate, the turntable 4 drives the driving pin 5 to rotate eccentrically, and the driving pin 5 drives the vertical rod 6 to perform reciprocating lifting motion through the rectangular slot 28. The vertical rod 6 drives each spraying rod 8 to perform reciprocating lifting motion through the liquid separator 7. The booster pump 10 transports the improver in the container 2 to each spraying rod 8, so that the improver is sprayed out from the liquid outlet 9 at high pressure during the lifting process of the spraying rod 8, so that the improver is directly sprayed into each layer of soil.

[0034] In order to achieve the purpose of improving the improvement effect of soil structure, preferably, the internal part of the separation box 7 is rotatably connected to the water wheel blade 12, the water wheel blade 12 is coaxially provided with a large gear 13, and multiple spraying rods 8 are rotatably connected to the lower surface of the separation box 7, and multiple spraying rods 8 are provided with small gears 14 that mesh with the large gear 13.

[0035] Specifically, when the improver passes through the liquid separator 7, the water wheel blades 12 inside the liquid separator 7 are impacted by the liquid flow and rotate. The rotating water wheel blades 12 drive the large gear 13 to rotate, and the large gear 13 drives the various spray rods 8 to rotate through the various small gears 14. On the one hand, the rotating spray rods 8 facilitate drilling in and out of the soil, reducing the drilling difficulty, reducing the wear of the spray rods 8, and extending their service life. On the other hand, it helps to continuously change the direction of the liquid outlet 9 when spraying the improver, improving the uniformity of the improver in the horizontal direction, and enhancing the improvement effect of the soil structure.

[0036] In order to achieve the purpose of improving the improvement effect of the soil structure, preferably, the hose 11 is connected to an L-shaped valve body 15 fixedly connected to the carrier 1, a retaining ring 16 is provided inside the vertical section of the L-shaped valve body 15, and a valve stem 17 is vertically slidably connected to the vertical section of the L-shaped valve body 15, and the lower end of the valve stem 17 is a conical structure.

[0037] The turntable 4 is coaxially provided with a driving pulley 18, and a reciprocating screw rod 19 is rotatably connected to the carrier 1. A shuttle 20 is threadedly connected to the reciprocating screw rod 19, and the shuttle 20 is fixedly connected to the valve stem 17. A driven bevel gear 21 is provided at the upper end of the reciprocating screw rod 19, and the driven bevel gear 21 is engaged with a driving bevel gear 22 rotatably connected to the transmission box 3. A driven pulley 23 is coaxially provided with the driving bevel gear 22, and a belt 24 is connected between the driving pulley 18 and the driven pulley 23.

[0038] Specifically, the driving pulley 18 rotates synchronously with the turntable 4, and the driving pulley 18 drives the driven pulley 23 to rotate through the belt 24, and the driven pulley 23 drives the driving bevel gear 22 to rotate, and the driving bevel gear 22 drives the reciprocating screw rod 19 to rotate through the driven bevel gear 21, and the reciprocating screw rod 19 drives the valve stem 17 to perform reciprocating lifting motion through the shuttle 20, so that the valve stem 17 and the spraying rod 8 are lifted and lowered synchronously. Since the lower end of the spraying rod 8 is a conical structure, the gap between the spraying rod 8 and the retaining ring 16 is continuously reduced during the descent process, thereby continuously reducing the flow rate of the improver, so that the improver sprayed on the upper soil is relatively less, while the improver sprayed on the lower soil is relatively more, which is beneficial to prevent the upper improver from penetrating into the lower soil, resulting in uneven spraying of the improver, and is beneficial to control the spraying amount and improve the improvement effect of the soil structure.

[0039] In order to achieve the purpose of adjusting the spraying depth of the improver, preferably, a guide groove 25 is radially provided on the turntable 4, a trapezoidal screw rod 26 is rotatably connected to the guide groove 25, a screw nut 27 that is slidably connected to the rectangular groove 25 is threadedly connected to the trapezoidal screw rod 26, and the drive pin 5 is provided on the screw nut 27.

[0040] Specifically, the insertion depth of the spraying rod 8 is adjusted according to the depth of the soil that needs to be improved. During the specific operation, the trapezoidal screw 26 is rotated forward or reverse, and the trapezoidal screw 26 drives the screw nut 27 close to or away from the center of the turntable 4. When the screw nut 27 drives the driving pin 5 close to the center of the turntable 4, the eccentricity of the driving pin 5 is reduced, the stroke of the spraying rod 8 becomes smaller, and the spraying depth of the improver becomes shallower. When the screw nut 27 drives the driving pin 5 away from the center of the turntable 4, the eccentricity of the driving pin 5 increases, the stroke of the spraying rod 8 becomes larger, and the spraying depth of the improver becomes deeper. It is easy to adjust and simple to operate.

[0041] Preferably, one end of the trapezoidal screw rod 26 is provided with an anti-slip structure, which is an anti-slip groove. Through the setting of the anti-slip structure, when adjusting the stroke of the spray rod 8, the static friction between the human hand and the trapezoidal screw rod 26 can be increased, thereby reducing the difficulty of operation and saving manpower.

[0042] A soil structure improvement method comprises the following steps:

[0043] S1: By rotating the trapezoidal screw 26, the eccentricity of the driving pin 5 is adjusted, thereby adjusting the spraying depth of the amendment in the soil;

[0044] S2: The carrier 1 moves on the soil to be improved, and the booster pump 10 transports the improver in the container 2 to the liquid separation box 7, which is then diverted by the liquid separation box 7 to each spraying rod 8. In the liquid separation box 7, the improver continuously impacts the water wheel blades 12, and the water wheel blades 12 drive the large gear 13 to rotate. The large gear 13 drives each spraying rod 8 to rotate through each small gear 14. The lifting mechanism drives the spraying rod 8 to continuously rise and fall, so that the spraying rod 8 performs a compound movement of lifting and rotating, and is inserted into the soil to spray the improver on each layer of the soil.

[0045] Compared with the prior art, the present invention is provided with a coordinated arrangement of a carrier 1, a transmission box 3, a turntable 4, a driving pin 5, a vertical rod 6, a rectangular groove 28, a driving part 18, a container 2, a liquid separation box 7, a spraying rod 8, a liquid outlet 9, a hose 11 and a booster pump 10. As the carrier 1 moves, the driving part 29 drives the turntable 4 to rotate, the turntable 4 drives the driving pin 5 to rotate eccentrically, the driving pin 5 drives the vertical rod 6 to perform reciprocating lifting motion through the rectangular groove 28, the vertical rod 6 drives each spraying rod 8 to perform reciprocating lifting motion through the liquid separation box 7, the booster pump 10 transports the improver in the container 2 to each spraying rod 8, so that the improver is sprayed out from the liquid outlet 9 at high pressure during the lifting process of the spraying rod 8, so that the improver is directly sprayed into the deep soil, which is beneficial to control the spraying amount and improve the improvement effect of the soil structure.
