Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of saline-alkali soil treatment, and particularly relates to a soil loosening device and method for saline-alkali soil treatment. BACKGROUND

[0002] Saline-alkali soil treatment is a global agricultural and environmental problem. In China, the area of saline-alkali soil is as high as 99.13 million hectares, which seriously restricts the development of agriculture. The main goal of saline-alkali soil treatment is to improve the physical and chemical properties of the soil to make it suitable for plant growth, thereby improving soil quality and agricultural production efficiency. The formation of saline-alkali soil is mainly related to the accumulation of salt in the soil, which may be due to poor water conditions, such as poor drainage or improper irrigation, causing the salt in the soil to be unable to drain, and long-term accumulation to form. In addition, carbonates and other minerals in the soil can also be converted into soluble salts under certain conditions, further exacerbating the salinization of the soil. There are many methods to treat saline-alkali soil, mainly including: physical methods: improving the water conditions of the soil through engineering measures, such as adding alkali discharge ditches, improving irrigation systems, etc. In addition, deep plowing and tillage can change the structure of the soil and reduce the accumulation of salt. Chemical methods: using chemical amendments, such as desulfurized gypsum and organic fertilizers, to change the salt content and properties of the soil through chemical reactions. Biological methods: using salt-tolerant plants and soil microorganisms to gradually reduce the salt and alkalinity of the soil. These plants and microorganisms can improve the soil environment by absorbing and transforming salt. Comprehensive improvement method: combining the above methods for comprehensive saline-alkali soil treatment to achieve the best results.

[0003] Currently, when treating saline-alkali soil, the soil structure is generally changed by rotary plowing, and then chemical amendments are sprayed into the rotary plowed soil. Although this can treat saline-alkali soil to some extent, since the chemical amendments are not sprayed into the interior of the soil during rotary plowing, the chemical amendments can only cover the surface of the soil and volatilize, so that the chemical amendments cannot fully react with the chemical substances in the saline-alkali soil, resulting in increased treatment costs and affecting the quality of saline-alkali soil treatment.

[0037] In use, the loosening machine 1 is installed on a tractor through the mounting frame 2, and the tractor is driven into the saline-alkali soil to loosen the saline-alkali soil. Then the motor 4 is started to drive the rotary tillage shaft 5 to rotate the rotary tillage blades 6, so that the rotary tillage blades 6 till the saline-alkali soil and loosen the saline-alkali soil. Until the whole saline-alkali soil is loosened, the motor 4 is turned off, and the tractor is driven away from the saline-alkali soil.

[0038] Referring to Figures 2-4 , Figure 6 , Figure 7 , Figure 9 The utility model further comprises a chemical agent storage cylinder 11 installed on the top of the loosening machine 1, a hollow rotating rod 14 rotatably connected to the chemical agent storage cylinder 11, driven wheels 10 fixedly connected to both ends of the hollow rotating rod 14, a connecting rod 17 fixedly connected to the part of the hollow rotating rod 14 located in the chemical agent storage cylinder 11, a zeolite tube 18 fixedly connected to one end of the connecting rod 17 away from the hollow rotating rod 14, a filter screen 19 fixedly connected to the inner bottom of the chemical agent storage cylinder 11, air extraction cylinders 15 fixedly connected to both ends of the hollow rotating rod 14, and fan blades 16 fixedly connected to the air extraction cylinders 15.

[0039] In use, the sealing plug 13 on the chemical agent adding pipe 12 is first opened to add chemical improving agent into the chemical agent storage cylinder 11. The chemical improving agent entering the chemical agent storage cylinder 11 will cover the zeolite tube 18. Since the chemical improving agent is a solution containing water, the zeolite tube 18 will heat the chemical improving agent. When the rotary tillage shaft 5 works, the hollow rotating rod 14 will be driven to rotate through the driving wheels 8, the belts 9 and the driven wheels 10, so that the air extraction cylinders 15 and the fan blades 16 rotate. The rotation of the fan blades 16 will suck the external air into the hollow rotating rod 14, and then the air will enter the zeolite tube 18 through the connecting rod 17, and be injected into the chemical improving agent through the rotation of the zeolite tube 18.

[0040] The uniformity of the chemical modifier is improved, and more air can be dissolved in the chemical modifier, so that the chemical modifier has high temperature and high oxygen content when sprayed into the soil through the spray holes 21, facilitating the reaction of the chemical modifier with chemical substances in the saline-alkali soil, improving the reaction rate, and thereby improving the efficiency of saline-alkali soil treatment.

[0041] With reference to Figures 1-5 、 Figures 7-9 The loosening machine 1 further comprises a spray plate 20 fixedly connected to the top of the loosening machine 1, a plurality of spray holes 21 are formed in the spray plate 20, and the number of the spray holes 21 is greater than or equal to twenty-seven; a fixed plate 22 is fixedly connected to the spray plate 20, a worm wheel 25 is rotatably connected to the fixed plate 22, a worm 7 is fixedly connected to the rotary tillage shaft 5 between the rotary tillage blades 6, a limiting block 26 is fixedly connected to the worm wheel 25, a loosening rod 27 is slidably connected to the worm wheel 25, a limiting groove 28 is formed in the loosening rod 27, a crushing head 29 is fixedly connected to the bottom of the fixed plate 22, and air injection holes 30 are formed on the upper and lower sides of the crushing head 29, wherein the limiting groove 28 is matched with the limiting block 26, the loosening rod 27 penetrates through the fixed plate 22 and is slidably connected with the fixed plate 22, the worm 7 is engaged with the worm wheel 25, and the rotary tillage blades 6 are arranged between the spray plates 20; the loosening machine 1 further comprises a lifting plate 31 rotatably connected to the top of the loosening rod 27, and cleaning blocks 32 are fixedly connected to the two ends of the lifting plate 31, wherein the spray plate 20 is fixedly connected with a reciprocating plate 23, a sliding groove 24 is formed in the spray plate 20, the loosening rod 27 penetrates through the reciprocating plate 23 and is connected with the reciprocating plate 23 through threads, the cleaning blocks 32 can slide up and down in the sliding groove 24, and the rotary tillage blades 6 are matched with the cleaning blocks 32; the loosening machine 1 further comprises a piston cylinder 34 fixedly connected to the bottom of the loosening machine 1, an air inlet pipe 35 is fixedly connected to the top of the piston cylinder 34, an air outlet pipe 36 is fixedly connected to the end of the air inlet pipe 35 away from the piston cylinder 34, and a piston plate 33 is slidably connected to the piston cylinder 34, wherein the piston plate 33 is fixedly connected to the top of the lifting plate 31.

[0042] The chemical modifier entering the storage cylinder 11 will pass through the filter screen 19 into the spray plate 20, and then be sprayed into the rotary tilled soil through the spray holes 21. When the rotary shaft 5 rotates, it will drive the worm 7 to rotate, and then drive the worm wheel 25 to rotate. Due to the arrangement of the limiting block 26 and the limiting groove 28, the rotation of the worm wheel 25 will drive the loosening rod 27 to rotate, and then drive the crushing head 29 to rotate, further crushing the soil rotary tilled by the rotary tillage blade 6. The rotation of the loosening rod 27 will make the loosening rod 27 move up and down under the action of the reciprocating plate 23, so that the crushing head 29 is crushed transversely and longitudinally. At the same time, the up-and-down movement of the loosening rod 27 will also make the lifting plate 31 move up and down, so that the cleaning block 32 slides up and down along the inner side wall of the sliding groove 24 to clean the outer surface of the rotary tillage blade 6. At the same time, the up-and-down movement of the lifting plate 31 will drive the piston plate 33 to slide up and down along the inside of the piston cylinder 34. The hot gas flow in the storage cylinder 11 is drawn into the air inlet pipe 35 through the air exhaust pipe 36, and then enters the piston cylinder 34. The hot gas flow entering the piston cylinder 34 will enter the loosening rod 27 and be blown into the loose soil through the air injection hole 30.

[0043] On the one hand, it can further crush the soil rotary tilled, so that the chemical modifier can quickly act on the saline-alkali soil. On the other hand, it can intermittently inject hot gas flow into the rotary tilled soil through the air injection hole 30, so as to promote the chemical reaction of the chemical modifier and the chemical components in the saline-alkali soil, improve the efficiency of the saline-alkali soil treatment, and ensure the quality of the saline-alkali soil treatment.

[0044] At the same time, the cleaning block 32 slides up and down in the sliding groove 24 to wipe and clean the rotary tillage blade 6 passing through the cleaning block 32, preventing the rotary tillage blade 6 from adhering soil due to long-term work and spraying of the chemical modifier, affecting the sharpness of the rotary tillage blade 6, thereby affecting the rotary tillage of the rotary tillage blade 6, and preventing the chemical modifier from corroding the rotary tillage blade 6, thereby protecting the rotary tillage blade 6 and prolonging the service life of the rotary tillage blade 6.

[0045] Referring to Figure 5 , Figure 9 Further comprising a fixed tube 37 fixedly connected to the top of the loosening machine 1, a connecting disc 39 slidably connected in the fixed tube 37, a knocking rod 38 fixedly connected in the connecting disc 39, a knocking spring 40 fixedly connected to the bottom of the connecting disc 39, the fixed tube 37 being fixedly connected to the bottom of the storage cylinder 11, the knocking rod 38 penetrating through and slidably connected with the storage cylinder 11 and the piston cylinder 34, the bottom of the knocking spring 40 being fixedly connected with the top of the loosening machine 1, the knocking rod 38 being arranged at the bottom of the filter screen 19 and being matched with the filter screen 19, and the knocking rod 38 being attracted to the piston plate 33.

[0046] During the sliding of the piston plate 33 up and down, the piston plate 33 will intermittently adsorb the knocking rod 38, and when the piston plate 33 adsorbs the knocking rod 38 and slides downward to the maximum adsorption force of the piston plate 33 and the knocking rod 38 (in this process, the knocking spring 40 will be gradually compressed), at this time, the knocking rod 38 will slide upward to knock the filter screen 19 under the action of the compressed knocking spring 40 and the connecting disc 39, so that the filter screen 19 vibrates;

[0047] The presence of particles in the chemical modifier is prevented from blocking the filter screen 19, causing the chemical modifier to be unable to be sprayed through the spray hole 21, and the presence of particles in the chemical modifier is prevented from blocking the spray hole 21 through the setting of the filter screen 19, thereby ensuring the treatment efficiency of the saline-alkali soil.

[0048] Referring to Figures 1-9 A soil loosening method for saline-alkali soil treatment, comprising the following steps:

[0049] Step 1: connect the loosening machine 1 to the tractor through the mounting bracket 2;

[0050] Step 2: open the sealing plug 13 and add a sufficient amount of chemical modifier into the agent storage cylinder 11 through the agent adding pipe 12;

[0051] Step 3: start the tractor and the motor 4 to loosen the saline-alkali soil through the rotary tillage blade 6;

[0052] Start the motor 4 to make the rotary tillage shaft 5 drive the rotary tillage blade 6 to rotate, so that the rotary tillage blade 6 tills the saline-alkali soil, loosens the saline-alkali soil, and completes the loosening of the entire saline-alkali soil;

[0053] When the rotary tillage shaft 5 is working, the hollow rotating rod 14 will be driven to rotate by the driving wheel 8, the belt 9 and the driven wheel 10, and then the air suction cylinder 15 and the fan blade 16 will be rotated, the rotation of the fan blade 16 will suck the external air into the hollow rotating rod 14, and then the air will enter the zeolite pipe 18 through the connecting rod 17, and then the air will be injected into the chemical modifier through the rotation of the zeolite pipe 18, which improves the uniformity of the chemical modifier and makes the chemical modifier dissolve more air, so that the chemical modifier has a high temperature and a high oxygen content when it is sprayed into the soil through the spray hole 21, which facilitates the reaction of the chemical modifier with the chemical substances in the saline-alkali soil, improves the reaction rate, and improves the efficiency of the saline-alkali soil treatment;

[0054] The chemical modifier entering the storage cartridge 11 will pass through the filter screen 19 into the spray plate 20, and then be sprayed into the rotary cultivated soil through the spray holes 21. When the rotary shaft 5 rotates, it will drive the worm 7 to rotate, and then drive the worm wheel 25 to rotate. Due to the arrangement of the limiting block 26 and the limiting groove 28, the rotation of the worm wheel 25 will drive the loosening rod 27 to rotate, and then drive the crushing head 29 to rotate, further crushing the soil rotary cultivated by the rotary blade 6. The rotation of the loosening rod 27 will make the loosening rod 27 move up and down under the action of the reciprocating plate 23, so that the crushing head 29 is crushed transversely and longitudinally. At the same time, the up-and-down movement of the loosening rod 27 will also make the lifting plate 31 move up and down, so that the cleaning block 32 slides up and down along the inner side wall of the sliding groove 24 to clean the outer surface of the rotary blade 6. At the same time, the up-and-down movement of the lifting plate 31 will drive the piston plate 33 to slide up and down along the inside of the piston cylinder 34. The hot gas flow in the storage cartridge 11 is drawn into the air inlet pipe 35 through the air exhaust pipe 36, and then enters the piston cylinder 34. The hot gas flow entering the piston cylinder 34 will enter the loosening rod 27 and be blown into the loose soil through the air injection hole 30. On the one hand, it can further crush the rotary cultivated soil, so that the chemical modifier can quickly act on the saline-alkali soil. On the other hand, it can intermittently inject hot gas flow into the rotary cultivated soil through the air injection hole 30, so as to promote the chemical reaction between the chemical modifier and the chemical components in the saline-alkali soil, improve the efficiency of saline-alkali soil treatment, and ensure the quality of saline-alkali soil treatment. At the same time, the cleaning block 32 slides up and down in the sliding groove 24 to wipe and clean the rotary blade 6 passing through the cleaning block 32, preventing the rotary blade 6 from adhering soil due to long-term work and spraying of the chemical modifier, affecting the sharpness of the rotary blade 6, thereby affecting the rotary cultivation of the rotary blade 6 on the soil, and preventing the chemical modifier from corroding the rotary blade 6, thereby protecting the rotary blade 6 and prolonging the service life of the rotary blade 6.

[0055] During the up-and-down sliding of the piston plate 33, the piston plate 33 will intermittently adsorb the knocking rod 38. When the piston plate 33 adsorbs the knocking rod 38 and slides downward to the maximum adsorption force of the piston plate 33 and the knocking rod 38 (in this process, the knocking spring 40 will be gradually compressed), at this time, the knocking rod 38 will slide upward under the action of the compressed knocking spring 40 and the connecting disc 39 to knock the filter screen 19, so that the filter screen 19 vibrates.

[0056] Step four: turn off the motor 4 after loosening is completed.
