Description

TECHNICAL FIELD

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

[0002] Saline-alkali soil is a kind of salt accumulation, which refers to the salt contained in the soil affecting the normal growth of crops, and the formation of alkali soil and alkalized soil is mostly related to the accumulation of carbonate in the soil, so the alkalization degree is generally high, and such soil is not suitable for the growth of most crops.

[0003] The existing saline-alkali soil improvement is mostly to first plow the surface soil of the saline-alkali soil through a rotary plowing mechanism, and then spread the improvement liquid and fertilizer into the plowed land through a fertilizer spreader, so as to realize the improvement of the saline-alkali soil. However, the effect of improving the saline-alkali soil by spreading the improvement liquid is limited, and the cost is high. In some areas, a buried pipe is used to irrigate water into the saline-alkali soil, so that the soil salt is dissolved, and the soluble salt in the surface soil layer is removed to the deep soil or leached out, and then the water is infiltrated into the buried pipe for removal. However, as the salt water enters the salt removal pipe through the water infiltration hole and the through hole, the soil and the like will block the filter screen, resulting in a decrease in the water inflow, and a decrease in the salt removal treatment effect.

[0004] In order to improve the improvement effect and reduce the improvement cost, paper-based solar desalination equipment is used in some areas, which mainly consists of a straw wrapped with filter paper and black mulch. The filter paper can be made of agricultural and forestry waste such as straw and sawdust, and the black mulch converts sunlight into infrared light to drive the filter paper to absorb salt water in the soil through capillary action. After the water evaporates, the salt crystals on the outer wall of the straw, thereby realizing one-way migration of salt from the soil to the desalination device and zero wastewater discharge. It realizes zero freshwater consumption and zero wastewater discharge, directly uses soil salt water, is environmentally friendly, and is efficient and durable. Under ideal conditions, one mu of land can be repaired in three to four days, and the effect of one repair can be maintained for 2 to 3 years. However, in actual use, as the water evaporates, the salt crystals adhere to the outer wall of the straw, which can easily affect the water evaporation effect when the salt crystals on the outer wall of the straw are too much, and the excessive salt on the outer wall of the straw can easily weaken its superhydrophilic property (the filter paper can quickly absorb water, but after the salt layer is covered, it may become a "hydrophobic surface"), further reducing the water migration efficiency, forming a vicious cycle of "the more blocked, the drier, the drier, the more blocked", thereby seriously affecting the saline-alkali soil improvement efficiency.

9. The saline-alkali land improvement equipment according to claim 1, characterized in that: Both the vertical rod (402) and the mounting plate (403) are made of heat-conducting material, and the mounting plate (403) is provided with a guide rod (9) that cooperates with the connecting rope (504).

10. A method for improving saline-alkali land improvement equipment according to any one of claims 1-9, characterized in that, Includes the following steps: S1. When in use, the salt water moves upward along the filter paper (3) under capillary action. Then, under the sun's rays, the water in the salt water gradually evaporates, and the salt crystals in the salt water adhere to the surface of the filter paper (3). When the sun sets at night, the temperature drops rapidly. At this time, the shape memory alloy wire (404) contracts, and during the contraction of the shape memory alloy wire (404), the bristles (407) move downward and clean the salt crystals on the surface of the filter paper (3). S2. Then, as the mounting plate (403) moves downward, the connecting rope (504) drives the horizontal plate (501) to move along the horizontal groove and compress the first spring (502). During the movement of the horizontal plate (501), the brush bristles (407) are driven to disengage from the filter paper (3) through the arc plate (406). Then, during the movement of the horizontal plate (501), the fixing hole (603) is driven to contact the fixing rod (601). At this time, the linkage spring (602) extends and drives the fixing rod (601) to insert into the fixing groove, thereby fixing the horizontal plate (501). When the reset pad (408) extends and drives the brush bristles (407) to move upward through the mounting plate (403), connecting plate (405), horizontal plate (501), and arc plate (406), it can prevent the brush bristles (407) from contacting the filter paper (3) during the upward movement. S3. During the process of the mounting plate (403) moving downward and compressing the reset pad (408), the airflow in the cavity (706) is squeezed and flows into the arc-shaped airbag (705) through the air tube (707). Then the arc-shaped airbag (705) extends and drives the connecting block (703) to rotate around the arc-shaped groove (704). During the rotation of the connecting block (703) around the arc-shaped groove (704), the mounting ring (701) is driven to rotate. During the rotation of the mounting ring (701), the stirring rod (702) is driven to rotate. During the rotation of the stirring rod (702), the salt crystals in the collection box (401) can be stirred. S4. As the mounting ring (701) drives the stirring rod (702) to rotate, the stirring rod (702) gradually contacts the push rod (807) and applies a thrust to the push rod (807). Under the action of the thrust, the push rod (807) drives the rack (806) to move. Then, during the movement of the rack (806), it drives the gear (804) to rotate. At this time, the second torque spring (805) begins to store power. During the rotation of the gear (804), it drives the mounting arc plate (801) to rotate through the linkage gear (803). During the rotation of the mounting arc plate (801), it drives the thin rod (802) to hit the bristles (407), so that the salt crystals adhering to the bristles (407) can be separated from the bristles (407).
