Description

Technical Field

[0001] The present application relates to the technical field of water-soil separation in saline-alkali land, and in particular to a saline-alkali land soil improvement device. Background Art

[0002] In the agricultural field, land salinization not only endangers the soil conditions on which crops depend for survival, but also affects the growth of crops, causing crop seedling shortages or death, thereby hindering the development of agricultural production. Soil salinization is an important limiting factor in the development of the local agricultural economy.

[0003] The core of the improvement work for saline-alkali soil is to reduce the salt and alkalinity in the soil to restore it to conditions suitable for crop growth. Among them, acid-base balance treatment is a core step in the improvement process, which usually relies on adding acidic or alkaline substances to finely control the pH value of the soil to ensure that it is within the ideal range for crop growth. After completing the acid-base balance treatment, the next step is to separate the water and soil from the treated soil (muddy), and the commonly used separation technologies cover a variety of methods including physical separation, chemical separation and centrifugal separation.

[0004] When physical separation is used to separate soil from water, double filter plates are usually used to clamp and squeeze the soil so that excess water can pass through the filter plates. However, in the preparation work before squeezing, the soil needs to be evenly spread on the filter plates to ensure that the forces on all parts of the filter plates are balanced. This step requires additional manpower and may require the installation of additional balancing equipment, which undoubtedly increases the operating cost and affects the efficiency of the squeezing process to a certain extent.

Detailed implementation manners

[0027] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0028] The saline-alkali soil improvement device of the embodiments of the present application will be described below with reference to the drawings.

[0029] As Figure 1-Figure 4 shown, the saline-alkali soil improvement device of the embodiments of the present application may include a base 10, a housing 20, an extrusion mechanism 30, an extrusion plate group 40, and a moving member 50.

[0030] Among them, a receiving groove 101 is provided on the top surface of the base 10, and a liquid discharge port 102 is provided on one side of the receiving groove 101. The housing 20 is arranged on the gantry 11, and the gantry 11 is arranged on the base 10.

[0031] The extrusion mechanism 30 is arranged in the housing 20, and it may include a driving member 31 and an output shaft group 32. Among them, the driving member 31 is connected to the output shaft group 32, the output shaft group 32 is movably arranged through the housing 20, the output shaft group 32 may include a first driving shaft 321 and a second driving shaft 322 arranged inside and outside, and a C-shaped frame 60 is provided on the second driving shaft 322, and the opening of the C-shaped frame 60 faces the receiving groove 101.

[0032] The extrusion plate group 40 is arranged above the receiving groove 101, and it may include a first plate body 41 and a second plate body 42 arranged up and down. Among them, the first plate body 41 is connected to the first driving shaft 321, the second plate body 42 is detachable and is slidably arranged inside the U-shaped frame 60. Sliding grooves 61 are respectively formed on the inner walls of both sides of the U-shaped frame 60, and sliding blocks 43 are arranged on both symmetric sides of the second plate body 42. The sliding blocks 43 are slidably placed in the corresponding sliding grooves 61. A plurality of filter holes 421 are formed on the second plate body 42. An extrusion groove 422 is arranged on the top surface of the second plate body 42, and a detachable filter layer 4221 is arranged inside the extrusion groove 422. The extrusion groove 422 is movably sleeved outside the first plate body 41. The extrusion plate group 40 can limit the soil to be processed inside the extrusion groove 422 and efficiently perform the extrusion and separation operation inside the extrusion groove 422, effectively preventing soil overflow and greatly enhancing the stability and controllability during the soil separation process.

[0033] It should be noted that the filter layer 4221 described in this embodiment is detachable and is arranged inside the extrusion groove 422. The operator only needs to place the soil on the filter layer 4221. During the process of soil extrusion and filtration, the liquid components contained in it can smoothly penetrate through the filter layer 4221 and the filter holes 421, flow into the lower receiving groove 101, and can be easily collected through the liquid discharge port 102; while the solid components are effectively retained above the filter layer 4221. For the collection of the solid components, only the filter layer 4221 needs to be separated from the second plate body 42 and the solid components remaining at the bottom of the first layer plate are collected, which greatly facilitates the collection operation.

[0034] The moving component 50 is arranged in the accommodation cavity on the base 10, and the moving component 50 is detachably connected to the second plate body 42. A positioning shaft 70 is arranged through the receiving groove 101. The upper end of the positioning shaft 70 abuts against the bottom of the second plate body 42, and the lower end of the positioning shaft 70 is connected to the moving component 50. A positioning groove 423 is arranged in the middle of the bottom surface of the second plate body 42, and the upper end of the positioning shaft 70 is slidably embedded in the positioning groove 423. A diversion plate 80 is arranged in the receiving groove 101. The diversion plate 80 is in an upward conical shape and its bottom surface is inclined. A through hole 81 for the positioning shaft 70 to pass through is arranged on the diversion plate 80, and a sealing ring 82 is arranged at the top of the through hole 81. The sealing ring 82 is sleeved outside the positioning shaft 70. The arranged diversion plate 80 can divert the liquid falling from the second plate body 42, which helps the liquid in the receiving groove 101 to be discharged through the liquid discharge port 102. The arranged sealing ring 82 can seal the through hole 81 to prevent the liquid falling from the second plate body 42 from entering the through hole 81 and affecting the smooth operation of the positioning shaft 70.

[0035] It should be noted that the moving part 50 described in this embodiment can be a cylinder, a telescopic motor 311, etc., and the moving part 50 has the ability to drive the positioning shaft 70 to move up and down. When the positioning shaft 70 rises, it can push the second plate 42 above to move toward the first plate 41; and when the positioning shaft 70 falls, the second plate 42 can slide freely inside the yoke 60, and the positioning shaft 70 provides a stable support for the second plate 42, ensuring that it can stably move away from the first plate 41.

[0036] It should be noted that the driving member 31 described in this embodiment can cause the first plate 41 and the second plate 42 to rotate synchronously in opposite directions. This function, combined with the driving of the second plate 42 by the moving member 50, allows the extrusion plate group 40 to rotate the first plate 41 and the second plate 42 in opposite directions while squeezing the soil through the regulation of the driving member 31, thereby achieving uniform spreading of the soil. This design not only reduces costs, but also improves the efficiency of extrusion separation.

[0037] Specifically, when it is necessary to separate soil and water from the soil (muddy) obtained by acid-base balance treatment of saline-alkali soil, the operator first lays the filter layer 4221 in the extrusion trough 422 and then places the soil on the filter layer 4221 .

[0038] Then, the operator can use the driving member 31 to cause the first plate 41 and the second plate 42 to rotate synchronously in opposite directions, and at the same time start the moving member 50, so that the moving member 50 pushes the second plate 42 to move toward the first plate 41, so that the squeezing plate group 40 can spread the soil evenly while squeezing the soil. This design not only reduces costs, but also improves the efficiency of squeezing separation.

[0039] During the process of soil extrusion and filtration, the liquid components contained therein can smoothly penetrate the filter layer 4221 and the filter holes 421, flow into the receiving tank 101 below, and be easily collected through the drain port 102. The solid components are effectively retained on the filter layer 4221. To collect the solid components, it is only necessary to simply separate the filter layer 4221 from the second plate body 42 and collect the solid components remaining at the bottom of the first plate, which greatly facilitates the collection operation.

[0040] In one embodiment of the present application, Figure 3-Figure 4As shown, the driving member 31 may include a motor 311, two gear rings 312 and two meshing gears 313, wherein the output end of the motor 311 is connected to the first driving shaft 321. The two gear rings 312 are arranged up and down, and the two are respectively connected to the inner wall of the housing 20 in a sliding manner, the first driving shaft 321 movably penetrates one gear ring 312 and is fixedly penetrated through the other gear ring 312, and the second driving shaft 322 is fixedly connected to the other gear ring 312. The two gears 313 are respectively arranged on the inner sides of the two gear rings 312, and the gears 313 are meshed with the corresponding gear rings 312. A mounting frame 21 is provided on one side of the gear 313, and the mounting frame 21 is connected to the inner wall of the housing 20, and the mounting frame 21 is located between the two gear rings 312.

[0041] Specifically, when the operator needs to use the driving member 31 to cause the first plate body 41 and the second plate body 42 to rotate in the opposite direction synchronously, the motor 311 is first started. The motor 311 can drive the first drive shaft 321 connected thereto to rotate synchronously, and the first drive shaft 321 can drive the gear ring 312 fixed thereto to rotate synchronously. This rotational action is further transmitted to the two mutually meshing gears 313, and through their intermediary effect, the other gear ring 312 is indirectly driven to rotate in the opposite direction. This reversely rotating gear ring 312 drives the second drive shaft 322 connected thereto to rotate in the opposite direction synchronously. Finally, the second drive shaft 322 is driven by the transmission of the yoke 60, so that the second plate body 42 rotates synchronously, thereby achieving the purpose of synchronously rotating the first plate body 41 and the second plate body 42 in the opposite direction.

[0042] In summary, the beneficial effects of the saline-alkali soil improvement device of the embodiment of the present application are: 1. While squeezing the soil through the extrusion plate group, the first plate body and the second plate body can be controlled to rotate in opposite directions through the driving member to achieve uniform spreading of the soil, thereby achieving the purpose of reducing costs and improving extrusion separation efficiency; 2. The extrusion plate group can confine the soil to be processed inside the extrusion trough, and efficiently perform the extrusion separation operation in the extrusion trough, effectively preventing soil overflow, and greatly enhancing the stability and controllability of the soil separation process; 3. The set filter layer and receiving trough can respectively collect the solid components and liquid components in the separated soil in an orderly manner, thereby realizing the effective classification and utilization of resources.
