Description

Technical Field

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

[0002] Soil turning equipment for soil remediation is a type of machinery mainly used to treat contaminated soil, improve soil structure and promote plant growth. During the herb planting process, soil turning can loosen compacted soil, improve soil aeration and drainage, and help the roots breathe better and absorb water and nutrients, thereby promoting the growth of herbs.

[0003] In the prior art, during the process of herb planting, turning equipment is needed to turn the soil, but most of the existing soil turning equipment simply turns the soil and is unable to collect and process the hard-to-break solid debris such as stones and hard glass in the soil. The gravel will physically hinder the extension and extension of the herb roots. The roots will change their growth direction when encountering gravel during the growth process and will not be able to expand normally to the deep soil layer and the surrounding areas, resulting in uneven and underdeveloped root distribution. The solid debris will reduce the soil porosity, increase the resistance to root growth, limit the root penetration ability, affect the root absorption of oxygen, and be detrimental to the normal respiration and metabolism of the root system, thereby reducing the practicality of the soil turning equipment for soil remediation.

[0015] A soil remediation method using a soil turning device comprises the following steps:

[0016] S1. During the herb planting process, an external tractor is started to drive the entire soil turning device to move in the herb planting farmland, and at the same time, a driving motor is started to turn the soil and break the soil, so that heavier stones can move farther under the action of centrifugal force and be collected inside the two perforated rollers. When the external tractor moves in the farmland, the two perforated rollers generate greater friction with the ground, and rotate along the two slots respectively. Through the pores set on the surface of the perforated rollers, the perforated rollers can flatten the turned soil and lay the soil in a neat grid shape;

[0017] S2. In order to prevent pollutants such as insect eggs and harmful bacteria in the soil from affecting the normal growth of herbs, the heating wire is first electrically connected to an external power source to heat the water source in the high-temperature box. When the temperature sensor detects that the water source in the high-temperature box is heated to the boiling point, the hot water pump is started to spray the hot water in the high-temperature box outward through the steam nozzle, thereby achieving the purpose of disinfecting harmful substances in the soil, so that the repaired soil is more conducive to the growth of herbs;

[0018] S3. In the process of using high-temperature hot water to disinfect the soil, in order to facilitate the continuous output of the high-temperature water source, the first solenoid valve is first opened to allow the normal-temperature water source in the water tank to enter the interior of the isolation box through the outlet pipe, so that the heating wire can indirectly heat the water source in the isolation box;

[0019] S4. When the water level sensor detects that the water source in the high-temperature box is low and needs to be replenished, the second solenoid valve is first opened through the external control system, so that the hot water in the isolation box quickly enters the interior of the high-temperature box, achieving a continuous supply of hot water in the high-temperature box.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When in use, during the process of herb planting, the external tractor and the driving motor are started to turn the soil and break the soil, so that the heavier stones move farther under the action of centrifugal force and are collected inside the two perforated rollers. When the external tractor moves in the farmland, the two perforated rollers generate greater friction with the ground and rotate along the two slots respectively, flattening the turned soil and paving the soil into a neat grid, which is convenient for herb planting and solves the problem that the soil turning equipment in the prior art during herb planting cannot remove hard pollutants in the soil and affect the healthy growth of herbs;

[0022] 2. When in use, in order to prevent pollutants such as insect eggs and harmful bacteria in the soil from affecting the normal growth of herbs, in the process of turning the soil, first connect the heating wire to the external power supply, heat the water source in the high-temperature box, start the hot water pump, and spray the hot water in the high-temperature box outward through the steam nozzle, so as to achieve the purpose of disinfecting harmful substances in the soil, so that the repaired soil is more conducive to the growth of herbs;

[0023] 3. During use, when using high-temperature hot water to disinfect the soil, in order to facilitate the continuous output of high-temperature water, open the first solenoid valve to allow the normal temperature water in the water tank to enter the interior of the isolation box through the outlet pipe, so that the heating wire can indirectly heat the water in the isolation box. When the water level sensor detects that the water in the high-temperature box is less and needs to be replenished, open the second solenoid valve to allow the hot water in the isolation box to quickly enter the interior of the high-temperature box, thereby achieving a continuous supply of hot water in the high-temperature box, further improving the working efficiency of the soil turning equipment for high-temperature disinfection of the soil.

A card slot 311 is provided on the inner wall of the hollow tube 310 near both ends. The insides of the two card slots 311 are rotatably connected with movable rings 312. The outer surfaces of the two movable rings 312 are fixed with a leaky roller 313 for rolling and flattening the soil. One end of one of the leaky rollers 313 is threadedly connected with a protective cover 314. The two ends of the crushing roller 304 are respectively movably penetrated to the opposite outsides of the tillage frame 301, and the bottom end of the connecting pipe 309 penetrates to the outside of the temporary storage bin 308. The top of the tillage frame 301 is provided with a mounting groove 4. The inside of the mounting groove 4 is provided with a disinfection component 5 for sterilizing the soil with high-temperature steam. The disinfection component 5 includes a high-temperature box 501. The bottom of the high-temperature box 501 is fixedly connected to the top of the tillage frame 301 by screws.

[0038] In this embodiment, during the herb planting process, in order to ensure the healthy growth of the herb, the connecting frame 1 is firstly connected to the external tractor equipment by bolts, so that the bottom of the tilling frame 301 is embedded in the soil, and then the external tractor is started to drive the entire soil turning device to move in the herb planting farmland, and at the same time, the driving motor 303 is started to drive the crushing roller 304 to rotate, wherein, as shown in FIG. Figure 2As shown, the outer surface of the crushing roller 304 is provided with a plurality of L-shaped oblique teeth, the purpose of which is to accelerate the turning of the soil and crush the soil. The stones and other hard pollutants in the soil, such as glass, are not easy to be crushed due to their hard material, so that they are larger in volume and mass relative to the crushed soil. During the rotation of the crushing roller 304, the soil is driven to rotate along the crushing roller 304. Due to the large mass and volume of the stones themselves, the inertia of the heavier objects under the action of centrifugal force is larger at the same angular velocity, which means that It is more difficult for them to change their own motion state, so that the heavier stones move a longer distance under the action of centrifugal force, so that they fly out through a plurality of elongated separation holes 305 and enter the interior of the separation frame 306. The soil blocks that enter the separation frame 306 together with the stones are broken by the bumps generated during the movement of the external tractor after entering the interior, and fall downward from the pores in the separation frame 306, so that the stones move downward along the inclined surface of the chute 307 and enter the interior of the temporary storage bin 308, wherein, as shown in FIG. Figure 3 As shown, the interior of the temporary storage bin 308 is arranged with a downwardly sloping surface in the center, and the purpose is to facilitate the materials entering the temporary storage bin 308 to move toward the connecting pipe 309. After entering the connecting pipe 309 along the sloping surface, the materials entering the temporary storage bin 308 move downward to the interior of the hollow tube 310 under the action of their own gravity, and finally fall into the interior of the two leak hole rollers 313, wherein, as shown in FIG. Figure 1 As shown, two leaky rollers 313 are arranged at the lower part of the soil turning device. When the external tractor moves in the farmland, the two leaky rollers 313 generate a large friction with the ground and rotate along the two slots 311 respectively. Figure 5 As shown, through the action of the two slots 311, the two perforated rollers 313 are limited and convenient for rotation. By moving large-particle gravel into the perforated roller 313, its mass can be increased, thereby increasing the friction between the perforated roller 313 and the ground. At the same time, through the pores set on the surface of the perforated roller 313, the perforated roller 313 can flatten the turned soil and lay the soil into a neat grid, which is convenient for the planting of herbs. When the soil remediation turning equipment has turned the soil, the protective cover 314 is rotated to separate it from the perforated roller 313, and the gravel in the perforated roller 313 can be taken out, that is, the separation and collection of hard pollutants in the soil during the planting of Chinese herbal medicines is realized, the soil is repaired, and the problem that the soil turning equipment in the prior art cannot remove the hard pollutants in the soil during the planting of Chinese herbal medicines and affects the healthy growth of herbs is solved.

[0040] In this embodiment, during the process of turning and repairing the soil during the process of planting herbs, in order to prevent pollutants such as insect eggs and harmful bacteria in the soil from affecting the normal growth of herbs, during the process of turning the soil, the heating wire 502 is first electrically connected to the external power supply to release heat energy outward, thereby heating the water source in the high-temperature box 501. When the temperature sensor 508 detects that the water source in the high-temperature box 501 is heated to the boiling point, the signal is transmitted to the external control system, wherein the temperature sensor 508 utilizes the law that various physical properties of substances change with temperature to convert the temperature into a usable output signal, and the hot water pump 504 is started through the external control system to allow the hot water in the high-temperature box 501 to enter the inside of the liquid outlet pipe 506 through the liquid inlet pipe 505, and finally to be sprayed outward through the steam nozzle 507. The high temperature of the hot water can make the proteins in the microbial cells The molecular structure of the substance changes, causing the protein to denature and coagulate.

[0043] In the present invention, during the herb planting process, in order to ensure the healthy growth of the herbs, the connecting frame 1 is firstly connected to the external tractor equipment by bolts, so that the bottom of the tilling frame 301 is embedded in the soil, and then the external tractor is started to drive the entire soil turning device to move in the herb planting farmland, and at the same time, the driving motor 303 is started to drive the crushing roller 304 to rotate to crush the soil. The stones and other hard pollutants in the soil, such as glass, are not easy to crush due to their hard material, so that they are larger in volume and mass relative to the already crushed soil. During the rotation of the crushing roller 304, the soil is driven to rotate along the crushing roller 304. Due to the large mass and volume of the stone itself, it is a heavier object under the action of centrifugal force. At the same angular velocity, its inertia is larger, so that the heavier stone moves a longer distance under the action of centrifugal force, so that it flies out through a plurality of elongated separation holes 305 and enters the interior of the separation frame 306. The soil blocks that enter the separation frame 306 together with the stones are broken by the bumps generated during the movement of the external tractor after entering the interior, and fall downward from the pores in the separation frame 306, so that the stones move downward along the inclined surface of the chute 307 and enter the interior of the temporary storage bin 308. The materials in the temporary storage bin 308 enter the connecting pipe 309 along the inclined surface, and then move downward to the interior of the hollow pipe 310 under the action of their own gravity, and finally fall into the two leak hole rollers 313. When the external tractor moves in the farmland, the two perforated rollers 313 generate a large friction force with the ground, and rotate along the two slots 311 respectively. Through the action of the two slots 311, the two perforated rollers 313 are limited and convenient for rotation. By moving large-grained gravel into the perforated roller 313, its mass can be increased, thereby increasing the friction between the perforated roller 313 and the ground. At the same time, through the pores set on the surface of the perforated roller 313, the perforated roller 313 can flatten the turned soil and lay the soil in a neat grid, which is convenient for the planting of herbs. When the soil remediation turning equipment has finished turning the soil, the protective cover 314 is rotated to separate it from the perforated roller 313. The gravel in the leaky drum 313 is taken out. In order to prevent pollutants such as insect eggs and harmful bacteria in the soil from affecting the normal growth of herbs, during the process of turning the soil, the heating wire 502 is first electrically connected to the external power supply to release heat energy outward, thereby heating the water source in the high-temperature box 501. When the temperature sensor 508 detects that the water source in the high-temperature box 501 is heated to the boiling point, the signal is transmitted to the external control system, and the hot water pump 504 is started through the external control system to allow the hot water in the high-temperature box 501 to enter the inside of the liquid outlet pipe 506 through the liquid inlet pipe 505, and finally sprayed outward through the steam nozzle 507, thereby achieving the purpose of disinfecting harmful substances in the soil, so that the repaired soil is more conducive to the growth of herbs. In addition,In order to prevent the turned-up soil from covering the inner top surface of the tillage frame 301 and affecting the spraying of high-temperature hot water, during the spraying of high-temperature hot water, the forward and reverse motor 702 is started to drive the screw rod 703 to rotate, thereby driving the scraper 704 to move along the inner top surface of the tillage frame 301, so as to scrape away the soil trapped on the inner top surface of the tillage frame 301, so that the high-temperature hot water will not be hindered in the process of spraying downward. In the process of using high-temperature hot water to disinfect the soil, in order to facilitate the continuous output of the high-temperature water source, the first solenoid valve 512 is first opened to allow the normal temperature water source in the water tank 510 to enter the interior of the isolation box 513 through the outlet pipe 511, so that the heating wire 502 can indirectly heat the water source in the isolation box 513. When the water level sensor 503 detects that the water source in the high-temperature box 501 is less and needs to be replenished, the second solenoid valve 515 is first opened through the external control system, so that the hot water in the isolation box 513 quickly enters the interior of the high-temperature box 501, realizing the continuous supply of hot water in the high-temperature box 501.
