Description

Technical Field

[0001] The present invention relates to the technical field of modifier spraying, and particularly to a modifier spraying device for saline-alkali land improvement. Background Art

[0002] Saline-alkali land refers to land in which the soil contains excessive salts and alkaline substances, thus affecting the normal growth of plants. The high concentration of salt ions in the soil solution can cause dehydration of plant roots, thereby inhibiting their growth and development. In addition, the high concentration of salts interferes with the absorption of nutrients by crops, destroys the absorption of other ions by crops, and causes crop nutrient disorders. Adding chemical substances such as gypsum, phosphogypsum, desulfurized gypsum, sulfur, humic acid, and furfural residues to the soil can reduce the pH value and alkalinity of the soil and achieve the improvement treatment of the soil structure of saline-alkali land. In actual saline-alkali land improvement, it is usually necessary to comprehensively use a variety of methods, combining engineering measures, agronomic measures, chemical measures, and biological measures to achieve the efficient improvement and sustainable utilization of saline-alkali land.

[0003] When the existing modifier spraying device sprays the modifier on the surface of saline-alkali land soil, due to the accumulation of salts on the surface of the saline-alkali land, there are soil lumps on the surface of the saline-alkali land soil. When directly spraying the soil modifier on the surface of the saline-alkali land soil, the soil modifier directly accumulates on the surface of the saline-alkali land soil and is difficult to directly enter the deep soil of the saline-alkali land, making it difficult to ensure the improvement effect of the soil modifier on the quality of the saline-alkali land. At the same time, the weeds existing on the surface of the saline-alkali land soil may interfere with the spraying effect of the soil modifier, making it difficult for the soil near the weeds to fully contact and react with the soil modifier. Therefore, the present application provides a modifier spraying device for saline-alkali land improvement to meet the requirements. Summary of the Invention

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting the weeding assembly, the elastic cooperation between the screw rod, the mounting plate and the elastic telescopic rod is used to realize the real-time adjustment of the horizontal height of the mounting plate, so as to realize the real-time adjustment of the cutting height of the plurality of blades. When spraying the soil conditioner on the surface of the saline-alkali soil, through the cooperation with the ditching plow, the weeds existing on the surface of the saline-alkali soil are cut to avoid the interference of the weeds existing on the surface of the saline-alkali soil on the spraying effect of the soil conditioner liquid. At the same time, through the soil turning effect of the soil turning mechanism on the saline-alkali soil, the broken parts of the weeds on the surface of the saline-alkali soil are turned into the deep part of the saline-alkali soil, and the quality of the deep soil of the saline-alkali soil is improved by the corruption substances generated by the rotten weeds, realizing the secondary utilization of the weeds.

[0016] By setting up the softening spraying component, through the linkage cooperation of two sets of bevel gears one and the reciprocating lead screw one, the cyclic replenishment of the soil conditioner liquid in the two liquid inlet barrels is realized. At the same time, the soil conditioner liquid stored in the mixing tank is shunted by the two liquid inlet barrels. Through the shunting effect of the shunt pipe and the water outlet pipe, the soil conditioner liquid stored in the mixing tank is shunted once, so that the shunted soil conditioner liquid flows out through the water outlet pipe and falls into the "V"-shaped deep groove plowed by the ditching plow, and the soil conditioner liquid continuously flows along the "V"-shaped deep groove, making the soil conditioner liquid fully contact with the soil near the inner wall of the "V"-shaped deep groove, and wetting and softening the inner wall of the "V"-shaped deep groove through the soil conditioner, improving the soil turning effect of the soil turning mechanism on the saline-alkali soil, and forming multiple soil conditioner flow bands on the surface of the saline-alkali soil, so that the soil conditioner liquid enters the deep soil layer of the saline-alkali soil under the action of penetration, improving the improvement effect of the soil conditioner on the deep soil layer of the saline-alkali soil. At the same time, through the shunting effect of the diversion pipe and the nozzle, the soil conditioner liquid stored in the mixing tank is shunted twice, and the shunted soil conditioner liquid is shunted and sprayed at the top position of the soil turning mechanism. At the same time, in cooperation with the overall crushing and soil turning effect of the soil turning mechanism on the surface of the saline-alkali soil, the shunted soil conditioner liquid is sprayed on the surface of the wetted saline-alkali soil for the second time. By spraying the soil conditioner on the surface and deep layer of the saline-alkali soil, the double mixing reaction of the soil conditioner in the surface soil and deep soil of the saline-alkali land is realized, further ensuring that the soil conditioner can fully mix and react with the saline-alkali soil, and improving the improvement effect of the soil conditioner on the soil quality of the saline-alkali soil.

[0017] By setting up the cutting component, through the linkage cooperation between the reciprocating lead screw group and the sliding base, the reciprocating sliding effect of the cutting edge knife is realized. At the same time, in cooperation with the forward movement of the traveling mechanism, the cutting edge knife forms a "Z" cutting trajectory between the "V"-shaped deep grooves, so as to form a through passage between two adjacent "V"-shaped deep grooves, and the soil conditioner liquid flowing in the "V"-shaped deep groove is diverted through the passage cut by the cutting edge knife, so that the soil conditioner flows in the soil between two adjacent "V"-shaped deep grooves, so as to realize that the soil on the inner wall of the "V"-shaped deep groove and the soil between the "V"-shaped deep grooves can both fully contact and react with the soil conditioner liquid, further ensuring the mixing reaction effect of the soil conditioner liquid and the saline-alkali soil. At the same time, the cutting edge knife cuts and breaks the soil surface between two adjacent "V"-shaped deep grooves, and pre-damages the soil surface between two adjacent "V"-shaped deep grooves. At the same time, through the flowing effect of the soil conditioner liquid in the "Z"-shaped passage, the soil surface between two adjacent "V"-shaped deep grooves is softened, ensuring the overall crushing and soil turning effect of the subsequent soil turning mechanism on the surface of the saline-alkali soil.

[0027] As Figures 1 to 12 shown, an embodiment of the present invention provides a modifier spraying device for saline-alkali land improvement, including a traveling mechanism 1. One end of the traveling mechanism 1 is installed with a mounting base 2. One side surface of the mounting base 2 is installed with a control module 3. The top end of the mounting base 2 is nested and installed with a water storage tank 4. One side of the bottom end of the water storage tank 4 is connected through a solenoid valve 5 to a mixing tank 50. The mixing tank 50 is nested and installed on one side of the top end of the mounting base 2. The bottom end inner wall of the mixing tank 50 is nested and installed with a mixing mechanism 6. The part of the bottom end of the mixing mechanism 6 extending out of the bottom end of the mixing tank 50 is connected to a motor 7. The motor 7 is installed on the inner wall of the mounting base 2. One end of the inner wall of the mounting base 2 is installed with multiple sets of ditching plows 8. The other end of the mounting base 2 is installed with a soil turning mechanism 80. One edge of the bottom end of one side of the mounting base 2 is installed with a weeding component 9. The weeding component 9 is used for weeding the weeds existing on the surface of the saline-alkali land soil. The bottom end inner wall of the mounting base 2 is installed with a softening spraying component 10. The softening spraying component 10 is used for softening the saline-alkali land soil after ditching. The bottom end inner wall of the mounting base 2 is installed with a cutting component 11. The cutting component 11 is used for cutting and connecting the saline-alkali land soil after ditching. The softening spraying component 10 is located on one side of the top of the weeding component 9. The cutting component 11 is located on one side of the weeding component 9.

[0028] By setting the weeding component 9, the weeds existing on the surface of the saline-alkali land soil are cut to avoid interference with the spraying effect of the soil modifier liquid on the surface of the saline-alkali land soil. By setting the softening spraying component 10, the soil modifier is sprayed on the surface and deep layer of the saline-alkali land soil to further ensure that the soil modifier can fully mix and react with the saline-alkali land soil, improving the improvement effect of the soil modifier on the soil quality of the saline-alkali land. By setting the cutting component 11, it is realized that the soil on the inner wall of the "V"-shaped deep groove and the soil between the "V"-shaped deep grooves can all fully contact and react with the soil modifier liquid, further ensuring the mixing and reaction effect of the soil modifier liquid and the saline-alkali land soil.

[0029] As Figures 3 to 4As shown, the weeding component 9 includes a motor 91. The motor 91 is installed at the bottom end of the inner wall of the installation base 2. The bottom end of the motor 91 is connected to a screw rod 92. The connection part between the motor 91 and the screw rod 92 is nested and installed at the bottom end of the inner wall of the installation base 2. A mounting plate 93 is sleeved on the outer surface of the screw rod 92 in a threaded manner. One side of the mounting plate 93 is equipped with two elastic telescopic rods 94. The top ends of the two elastic telescopic rods 94 are elastically connected to the bottom end of the installation base 2. On the other side of the mounting plate 93, a plurality of blades 95 are installed. The cross-section of one end of the blade 95 is designed in a "V" shape.

[0030] The operator first injects clean water into the water storage tank 4 and always ensures the water storage in the water storage tank 4. At the same time, the operator pours the soil conditioner into the mixing tank 50. Subsequently, the operator controls the solenoid valve 5 and the motor 7 to start simultaneously through the control module 3. The clean water stored in the water storage tank 4 is injected into the mixing tank 50 through the solenoid valve 5. After the motor 7 starts, it drives the mixing mechanism 6 to rotate continuously for mixing, so that the soil conditioner powder and clean water in the mixing tank 50 are fully mixed.

[0031] At the same time, the operator controls the motor 91 to start through the control module 3 according to the height of the weeds on the surface of the saline-alkali soil. After the motor 91 starts, it drives the screw rod 92 to rotate synchronously. Under the rotation of the screw rod 92, the mounting plate 93 sleeved on the outer surface of the screw rod 92 slides along the direction of the screw rod 92. While the mounting plate 93 slides, it drives the elastic telescopic rods 94 to stretch out. While the mounting plate 93 slides, it drives a plurality of blades 95 to slide synchronously, so that the blades 95 are at the same horizontal height as the roots of the weeds.

[0032] Subsequently, the operator operates the traveling mechanism 1 to perform a linear motion on the surface of the saline-alkali soil. The traveling mechanism 1 drives the installation base 2 to perform a linear motion synchronously. While the installation base 2 drives the ditch plow 8 to move straight forward along the surface of the saline-alkali soil, the soil lumps on the surface of the saline-alkali soil are broken by the ditch plow 8. At the same time, a plurality of "V" - shaped deep grooves are formed on the surface of the saline-alkali soil by the plurality of ditch plows 8. While the traveling mechanism 1 drives the installation base 2 to perform a linear motion synchronously, the installation base 2 drives the mounting plate 93 to perform a linear motion synchronously through the screw rod 92. While the traveling mechanism 1 drives the installation base 2 to move forward, the roots of the weeds on the surface of the saline-alkali soil are cut by the plurality of blades 95 at one end of the mounting plate 93, and the weeds on the surface of the saline-alkali soil are weeded.

[0033] By setting the elastic fit between the screw rod 92, the mounting plate 93 and the elastic telescopic rod 94, the real-time adjustment of the horizontal height of the mounting plate 93 is realized, so as to realize the real-time adjustment of the cutting height of multiple groups of blades 95. When spraying the soil conditioner on the surface of saline-alkali soil, through the cooperation with the furrow opener 8, the weeds existing on the surface of saline-alkali soil are cut to avoid the interference of the weeds existing on the surface of saline-alkali soil on the spraying effect of the soil conditioner liquid.

[0034] As Figures 5 to 10 shown, the softening spraying assembly 10 includes a ratchet disc 101, and the ratchet disc 101 is sleeved on the surface of the connection part of the stirring mechanism 6 and the motor 7. One side of the ratchet disc 101 is meshed with a first bevel gear 102. The number of the first bevel gears 102 is set to two groups. Both groups of the first bevel gears 102 are installed at the bottom end of the stirring tank 50. One end of both groups of the first bevel gears 102 is installed with a first reciprocating lead screw 103. The first reciprocating lead screw 103 is installed at the bottom end of the stirring tank 50. A push plate 104 is sleeved on the outer surface of the first reciprocating lead screw 103. The softening spraying assembly 10 further includes two liquid inlet barrels 105. The number of the liquid inlet barrels 105 is set to two groups. Both groups of the liquid inlet barrels 105 are installed at the bottom end of the inner wall of the mounting base 2. Piston discs 106 are slidably fitted on the inner walls of both groups of the liquid inlet barrels 105. One end of the piston disc 106 is connected to the push plate 104. One-way valves 107 are installed at one end of both groups of the liquid inlet barrels 105. The one-way valves 107 at one end of both groups of the liquid inlet barrels 105 are connected to the bottom end of the stirring tank 50 through hoses 108. One-way valves 109 are also installed at one end of both groups of the liquid inlet barrels 105. The one-way valve 109 at one end of one of the two groups of the liquid inlet barrels 105 is connected to a shunt pipe 1010. The shunt pipe 1010 is installed at the bottom end of the inner wall of the mounting base 2. A plurality of water outlet pipes 1011 are arrayed and penetrated on the bottom surface of the shunt pipe 1010. The one-way valve 109 at one end of the other liquid inlet barrel of the two groups of the liquid inlet barrels 105 is connected to a diversion pipe 1012. The diversion pipe 1012 is installed on the inner wall of the mounting base 2. A plurality of nozzles 1013 are arrayed and penetrated on the bottom surface of the diversion pipe 1012.

[0035] During this process, while the motor 7 drives the continuous rotation and stirring in the stirring mechanism 6, the connection part of the motor 7 and the stirring mechanism 6 drives the ratchet disc 101 to rotate synchronously. While the ratchet disc 101 rotates, it meshes with the first bevel gear 102. Under the rotation action of the ratchet disc 101, the two groups of the first bevel gears 102 rotate. While the two groups of the first bevel gears 102 rotate, they respectively drive the two groups of the first reciprocating lead screws 103 to rotate synchronously. Under the rotation action of the first reciprocating lead screw 103, the push plate 104 sleeved on the outer surface of the first reciprocating lead screw 103 slides reciprocally along the direction of the first reciprocating lead screw 103.

[0036] While one of the two sets of push plates 104 reciprocally slides, it drives the piston disc 106 in one of the liquid inlet barrels 105 to reciprocally slide synchronously. Under the sliding action of the piston disc 106, when the piston disc 106 slides in this liquid inlet barrel 105, it sucks the mixed soil conditioner liquid in the mixing tank 50 into the liquid inlet barrel 105 through the hose 108 and check valve one 107 at one end of this liquid inlet barrel 105. When the piston disc 106 slides reversely in this liquid inlet barrel 105, it squeezes the soil conditioner liquid in the liquid inlet barrel 105 through the check valve two 109 at one end of this liquid inlet barrel 105 into the shunt pipe 1010, and under the continuous squeezing action of the piston disc 106, the soil conditioner liquid is sprayed out through multiple water outlet pipes 1011 at the bottom end of the shunt pipe 1010, and the soil conditioner liquid sprayed out from the water outlet pipes 1011 enters the "V"-shaped deep groove plowed by the ditching plow 8, so that the soil conditioner liquid is fully mixed with the soil in the "V"-shaped deep groove, and the soil in the "V"-shaped deep groove is moistened and softened by the soil conditioner.

[0037] While the traveling mechanism 1 drives the mounting base 2 to perform a linear motion synchronously, the mounting base 2 drives the soil turning mechanism 80 at the other end to perform a linear motion synchronously, and the soil turning mechanism 80 fully crushes and turns over the saline-alkali soil.

[0038] Meanwhile, during this process, while the other set of push plates 104 in the two sets of push plates 104 reciprocally slides, it drives the piston disc 106 in the other liquid inlet barrel 105 to reciprocally slide synchronously. Under the sliding action of the piston disc 106, when the piston disc 106 slides in this liquid inlet barrel 105, it sucks the mixed soil conditioner liquid in the mixing tank 50 into the liquid inlet barrel 105 through the hose 108 and check valve one 107 at one end of this liquid inlet barrel 105. When the piston disc 106 slides reversely in this liquid inlet barrel 105, it squeezes the soil conditioner liquid in the liquid inlet barrel 105 through the check valve two 109 at one end of this liquid inlet barrel 105 into the diversion pipe 1012, and under the continuous squeezing action of the piston disc 106, the soil conditioner liquid is sprayed out through multiple nozzles 1013 at the bottom end of the diversion pipe 1012. After the soil conditioner liquid is sprayed out through the multiple nozzles 1013, it drops under the action of gravity and is fully mixed with the soil crushed by the soil turning mechanism 80, completing the improvement operation of the saline-alkali soil.

[0039] By setting the softening spraying component 10, through the linkage cooperation of two sets of bevel gears 102 and the first reciprocating lead screw 103, the cyclic replenishment of the soil conditioner liquid in the two liquid inlet barrels 105 is realized. At the same time, the soil conditioner liquid stored in the mixing tank 50 is shunted by the two liquid inlet barrels 105, and the soil conditioner is sprayed on the surface and deep positions of the saline-alkali soil, further ensuring that the soil conditioner can fully mix and react with the saline-alkali soil, and improving the improvement effect of the soil conditioner on the soil quality of the saline-alkali soil.

[0040] As Figures 11 to 12 shown, the cutting component 11 includes a pulley group 111, and the pulley group 111 is installed at the bottom end of the inner wall of the mounting base 2. One of the pulleys in the pulley group 111 is sleeved on the surface of the extended part of one of the first reciprocating lead screws 103, and the inner wall of the other pulley in the pulley group 111 is sleeved with a reciprocating lead screw group 112. The reciprocating lead screw group 112 is installed at the bottom end of the inner wall of the mounting base 2. The reciprocating lead screw group 112 is formed by splicing multiple reciprocating lead screws. Multiple sliding bases 113 are threadedly sleeved on the surface of the reciprocating lead screw group 112. A limiting rod 114 is sleeved in the middle inner wall of the sliding base 113, and the limiting rod 114 is installed on the inner wall of the mounting base 2. Cutting edge knives 115 are installed at the bottom ends of multiple sliding bases 113.

[0041] While the first reciprocating lead screw 103 rotates, it drives one of the pulleys in the pulley group 111 to rotate synchronously. While one of the pulleys in the pulley group 111 rotates, it drives the other pulley in the pulley group 111 to rotate synchronously through the belt. While the other pulley in the pulley group 111 rotates, it drives the reciprocating lead screw group 112 to rotate synchronously. Under the rotation action of the reciprocating lead screw group 112, multiple sliding bases 113 threadedly sleeved on the outer surface of the reciprocating lead screw group 112 reciprocate. While the sliding bases 113 reciprocate, under the limiting action of the limiting rod 114, they reciprocate along the direction of the limiting rod 114. While the sliding bases 113 slide, they drive the cutting edge knives 115 at the bottom ends to slide synchronously. At the same time, under the action of the traveling mechanism 1 driving the mounting base 2 to perform a linear motion, multiple cutting edge knives 115 form a "Z" cutting trajectory between the "V"-shaped deep grooves, forming a through channel between adjacent "V"-shaped deep grooves. At the same time, the soil conditioner liquid in the "V" shape flows in the "Z" cutting channel formed by the cutting edge knives 115, making the soil between adjacent "V"-shaped deep grooves and the soil conditioner liquid fully wet and mixed.

[0042] By setting the linkage cooperation between the reciprocating lead screw group 112 and the sliding base 113, the reciprocating sliding effect of the cutting edge knife 115 is achieved. The cutting edge knife 115 cuts and breaks the soil surface between two adjacent "V"-shaped deep grooves, and pre-damages the soil surface between two adjacent "V"-shaped deep grooves to ensure the overall crushing and soil-turning effect of the subsequent soil-turning mechanism 80 on the saline-alkali soil surface.

[0043] The working principle of the technical solution provided by the present invention is as follows: The operator first injects clean water into the water storage tank 4 and always ensures the storage amount of clean water in the water storage tank 4. At the same time, the operator pours the soil conditioner into the mixing tank 50. Subsequently, the operator controls the solenoid valve 5 and the motor 7 to start simultaneously through the control module 3. The clean water stored in the water storage tank 4 is injected into the mixing tank 50 through the solenoid valve 5. After the motor 7 starts, it drives the mixing mechanism 6 to continuously rotate and stir, so that the soil conditioner powder and clean water in the mixing tank 50 are fully mixed.

[0044] At the same time, the operator controls the motor 91 to start through the control module 3 according to the height of the weeds on the saline-alkali soil surface. After the motor 91 starts, it drives the screw 92 to rotate synchronously. Under the rotation of the screw 92, the mounting plate 93 sleeved with the thread on the outer surface of the screw 92 slides along the direction of the screw 92. While the mounting plate 93 slides, it drives the elastic telescopic rod 94 to stretch out. While the mounting plate 93 slides, it drives multiple groups of blades 95 to slide synchronously, so that the blades 95 are at the same horizontal height as the roots of the weeds.

[0045] Subsequently, the operator operates the traveling mechanism 1 to perform a linear motion on the saline-alkali soil surface. The traveling mechanism 1 drives the mounting base 2 to perform a linear motion synchronously. While the mounting base 2 drives the ditching plow 8 to move straight forward on the saline-alkali soil surface, the ditching plow 8 breaks the soil clumps on the saline-alkali soil surface, and at the same time forms multiple "V"-shaped deep grooves on the saline-alkali soil surface through multiple groups of ditching plows 8.

[0046] While the traveling mechanism 1 drives the mounting base 2 to perform a linear motion synchronously, the mounting base 2 drives the mounting plate 93 to perform a linear motion synchronously through the screw 92. While the traveling mechanism 1 drives the mounting base 2 to move forward, the multiple groups of blades 95 at one end of the mounting plate 93 cut the roots of the weeds to remove the weeds on the saline-alkali soil surface.

[0047] During the process, while the motor 7 drives the stirring mechanism 6 to continuously rotate and stir, the connecting part of the motor 7 and the stirring mechanism 6 drives the ratchet disc 101 to rotate synchronously. While the ratchet disc 101 rotates, it meshes with the first bevel gear 102. Under the rotation of the ratchet disc 101, the two groups of first bevel gears 102 rotate, and while the two groups of first bevel gears 102 rotate, they respectively drive the two groups of first reciprocating lead screws 103 to rotate synchronously. Under the rotation of the first reciprocating lead screw 103, the push plate 104 threadedly sleeved on the outer surface of the first reciprocating lead screw 103 slides reciprocally along the direction of the first reciprocating lead screw 103.

[0048] While one of the two groups of push plates 104 slides reciprocally, it drives the piston disc 106 in one of the liquid inlet barrels 105 to slide reciprocally synchronously. Under the sliding of the piston disc 106, when the piston disc 106 slides in this liquid inlet barrel 105, the mixed soil conditioner liquid in the mixing tank 50 is sucked into the liquid inlet barrel 105 through the hose 108 and the first one-way valve 107 at one end of this liquid inlet barrel 105. When the piston disc 106 slides reversely in this liquid inlet barrel 105, the soil conditioner liquid in the liquid inlet barrel 105 is squeezed into the shunt pipe 1010 through the second one-way valve 109 at one end of this liquid inlet barrel 105, and under the continuous squeezing of the piston disc 106, the soil conditioner liquid is sprayed out through the multiple water outlet pipes 1011 at the bottom of the shunt pipe 1010, and the soil conditioner liquid sprayed out from the water outlet pipes 1011 enters the "V"-shaped deep groove plowed by the ditching plow 8, so that the soil conditioner liquid is fully mixed with the soil in the "V"-shaped deep groove, and the soil in the "V"-shaped deep groove is moistened and softened by the soil conditioner.

[0049] At the same time, while the first reciprocating lead screw 103 rotates, it drives one of the pulley groups 111 to rotate synchronously. While one of the pulley groups 111 rotates, it drives the other pulley in the pulley group 111 to rotate synchronously through the belt. While the other pulley in the pulley group 111 rotates, it drives the reciprocating lead screw group 112 to rotate synchronously. Under the rotation of the reciprocating lead screw group 112, the multiple sliding bases 113 threadedly sleeved on the outer surface of the reciprocating lead screw group 112 slide reciprocally. While the sliding bases 113 slide reciprocally, under the limiting action of the limiting rod 114, they slide reciprocally along the direction of the limiting rod 114. While the sliding bases 113 slide, they drive the cutting edge knives 115 at the bottom to slide synchronously. At the same time, under the action of the traveling mechanism 1 driving the mounting base 2 to perform a linear motion, the multiple cutting edge knives 115 form a "Z" cutting trajectory between the "V"-shaped deep grooves, a through-channel is formed between adjacent "V"-shaped deep grooves, and at the same time, the soil conditioner liquid in the "V" shape flows in the "Z" cutting channel formed by the cutting edge knives 115, so that the soil between adjacent "V"-shaped deep grooves is fully moistened and mixed with the soil conditioner liquid.

[0050] While the traveling mechanism 1 drives the mounting base 2 to perform a linear motion synchronously, the mounting base 2 drives the soil-turning mechanism 80 at the other end to perform a linear motion synchronously, and the soil-turning mechanism 80 is used to fully break and turn the saline-alkali soil.

[0051] During this process, while the other set of push plates 104 in the two sets of push plates 104 reciprocally slide, they drive the piston disk 106 in the other set of liquid inlet barrels 105 to reciprocally slide synchronously. Under the sliding action of the piston disk 106, when the piston disk 106 slides in this set of liquid inlet barrels 105, the mixed soil conditioner liquid in the mixing tank 50 is sucked into the liquid inlet barrels 105 through the hose 108 and the first one-way valve 107 at one end of this set of liquid inlet barrels 105. When the piston disk 106 slides in the reverse direction in this set of liquid inlet barrels 105, the soil conditioner liquid in the liquid inlet barrels 105 is extruded into the diversion pipe 1012 through the second one-way valve 109 at one end of this set of liquid inlet barrels 105, and under the continuous extrusion action of the piston disk 106, the soil conditioner liquid is sprayed out through multiple nozzles 1013 at the bottom end of the diversion pipe 1012. After the soil conditioner liquid is sprayed out through the multiple nozzles 1013, it drops under the action of gravity and is fully mixed with the soil broken by the soil-turning mechanism 80, completing the improvement operation on the saline-alkali soil.
