DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention. Example

[0033] like Figures 1 to 8As shown, a saline-alkali land restoration device for promoting soil ecological balance includes an installation unit 100, a feeding unit 200 and a sealing unit 300. The installation unit 100 includes a rotating drum 102, the side wall of which is provided with four digging blades 1025, a built-in cavity 1024 is provided in the rotating drum 102, and the side wall of the rotating drum 102 is also provided with four rectangular notches 1023 distributed in a circumference; the sealing unit 300 includes a plurality of first sealing plates 3025 and a second sealing plate 3028, each first sealing plate 3025 and a second sealing plate 3028. 025 and the second sealing plate 3028 are symmetrical to each other, and each first sealing plate 3025 and the second sealing plate 3028 are respectively used to seal the outer wall of the rectangular slot 1023; the unloading unit 200 includes a servo motor 201 and a drive assembly and a piston plate 2035, the servo motor 201 is used to drive the rotating drum 102 to rotate, the drive assembly is used to drive the piston plate 2035 to move vertically, and the movement of the piston plate 2035 is used to drive the first sealing plate 3025 and the second sealing plate 3028 to close and open. First, when the drum 102 rotates, it can drive the piston plate 2035 to be lifted with the assistance of the driving assembly. When the piston plate 2035 is lifted, the soil salinization and alkali remediation raw materials can be discharged. Because when the piston plate 2035 rises, the aperture of the soil salinization and alkali remediation raw materials entering the rectangular slot 1023 is from small to large, that is, the raw materials entering are from small to more. At the same time, when the piston plate 2035 is lifted, it will be able to drive the guide block 3011 to approach the outer wall of the drum 102 through the fixed block 301. Because the guide block 3011 is provided with an inclined surface 3012, the soil salinization and alkali remediation raw materials can be discharged at a fast speed and a slow speed, which can achieve a relatively uniform discharge effect to a certain extent.

[0034] like Figures 1 to 8 As shown, in a specific embodiment, rotating rods 204 are respectively provided on the two side walls of the rotating drum 102. Second support plates 1022 and servo motors 201 are respectively provided on opposite ends of the two rotating rods 204. A first support plate 1021 is provided on the end of the servo motor 201 away from the second support plate 1022. The output end of the servo motor 201 is fixedly connected to the rotating rods 204. A cavity is defined within the rotating rods 204. Mounting brackets 101 are respectively provided on opposite ends of the first support plate 1021 and the second support plate 1022. This configuration defines the mounting and component parts on both sides of the rotating drum 102, ensuring that the rotating drum 102 can move. Example

[0035] The difference between Example 1 and this example is that: Figures 1 to 8As shown, a saline-alkali land restoration device for promoting soil ecological balance includes a drive assembly comprising a first special-shaped rod 203 and a second special-shaped rod 2039. The first special-shaped rod 203 and the second special-shaped rod 2039 are respectively composed of a semicircular ring and a concave ring. The first special-shaped rod 203 and the second special-shaped rod 2039 are symmetrical to each other. A fixed rod 202 is disposed within the first special-shaped rod 203 and the second special-shaped rod 2039. One end of the fixed rod 202 movably extends through a cavity defined in the rotating drum 102 and the rotating rod 204, and the end thereof is fixedly connected to the second support plate 1022. In this configuration, the installation position and components of the drive assembly are determined.

[0036] like Figures 6 to 8 As shown, in a specific embodiment, four connecting rods 2031 are fixedly connected to the inner cavities of the first and second shaped rods 2039. Opposite ends of each connecting rod 2031 are connected to the fixed rod 202. The outer walls of the first and second shaped rods 2039 are also provided with shaped slots 2032. In this arrangement, the connection relationship between the first and second shaped rods 2039 and the fixed rod 202 is confirmed.

[0037] like Figures 6 to 8 As shown, the special-shaped chute 2032 further includes a semi-annular chute 20321 and a semi-circular concave chute 20322. The semi-annular chute 20321 and the semi-circular concave chute 20322 are interconnected. Four balls 2033 are slidably disposed on the semi-annular chute 20321 and the semi-circular concave chute 20322. Positioning rods 2034 are disposed on the sides of the four balls 2033 away from the semi-annular chute 20321 and the semi-circular concave chute 20322. Opposite ends of each positioning rod 2034 are connected to a piston plate 2035, each of which fits into the rectangular notch 1023. This arrangement determines the installation position of the piston plate 2035 and ensures that the plug plate 2035 can move. Example

[0038] The difference between Example 2 and this example is that: Figures 6 to 8 As shown, a saline-alkali land restoration device for promoting soil ecological balance is provided. Four circumferentially distributed chute grooves 2036 are formed on opposite sides of the internal cavity 1024 of the rotating drum 102. Each chute groove 2036 is symmetrical with each other. A slider 2037 is slidably mounted within each chute 2036. Each slider 2037 is provided with a connecting rod 2038 at one end away from the chute 2036. The other end of each connecting rod 2038 is mounted on a positioning rod 2034. In this configuration, the installation position and components of the connecting rod 2038 are determined.

[0039] like Figures 1 to 8As shown, in a specific embodiment, a fixed block 301 is fixedly connected to one side wall of each of the four piston plates 2035, away from the internal cavity 1024. A guide block 3011 is fixedly connected to one end of each of the four fixed blocks 301, away from the piston plate 2035. Inclined surfaces 3012 are provided on both sides of the four guide blocks 3011. This arrangement ensures that when the piston plate 2035 is raised, the fixed block 301 drives the guide blocks 3011 toward the outer wall of the rotating drum 102. Furthermore, because the guide blocks 3011 are provided with inclined surfaces 3012, the soil salinization remediation raw materials can be fed at a faster rate and then a slower rate, achieving a relatively uniform feeding effect to a certain extent.

[0040] like Figures 1 to 8 As shown, further, two first movable rods 3024 and two second movable rods 3026 are respectively provided on both sides of the four guide blocks 3011. Each of the first movable rods 3024 is movably connected to the first movable plate 302, and each of the second movable rods 3026 is movably connected to the second movable plate 3027 at the opposite end. In this arrangement, when the guide block 3011 moves, it can drive the first movable plate 302 and the second movable plate 3027 to move horizontally with the assistance of the guide rods 3022 through the first movable rods 3024 and the second movable rods 3026, respectively.

[0041] like Figures 1 to 8 As shown, further, a fixed plate 3021 is provided on the opposite side of each first movable plate 302 and the second movable plate 3027. Each fixed plate 3021 is respectively provided on the rotating drum 102. A guide rod 3022 is provided on the opposite side of each fixed plate 3021. Each guide rod 3022 is movable between the first movable plate 302 and the second movable plate 3027. In this arrangement, the first movable plate 302 and the second movable plate 3027 are ensured to be able to move horizontally.

[0042] like Figures 1 to 8As shown, further, a telescopic rod 3023 is provided above each first movable plate 302 and the second movable plate 3027, a first sealing plate 3025 and a second sealing plate 3028 are respectively provided above each telescopic rod 3023, an arc-shaped slide rail 303 is provided between each first sealing plate 3025 and the second sealing plate 3028 and the rotating drum 102, and each arc-shaped slide rail 303 is provided on the rotating drum 102. In this arrangement, it is ensured that when the first movable plate 302 and the second movable plate 3027 move horizontally, the telescopic rod 3023 will be driven to move, so that the telescopic rod 3023 can respectively drive the first sealing plate 3025 and the second sealing plate 3028 to move in contact with the outer wall of the rotating drum 102 with the assistance of the arc slide rail 303, thereby ensuring that the first sealing plate 3025 and the second sealing plate 3028 can be opened, so that the soil salinization remediation raw materials can be unloaded, and when the positioning rod 2034 is reset, the first sealing plate 3025 and the second sealing plate 3028 can be closed to achieve sealing, thereby ensuring that when the excavating blade 1025 loosens the soil, the soil contaminated above it will not enter the rectangular slot 1023 when it falls from a high place.

[0043] The implementation principle of the saline-alkali land restoration device for promoting soil ecological balance of the present invention is as follows:

[0044] First, the staff uses the existing mechanical equipment to drive the mounting bracket 101 to move. When the mounting bracket 101 starts to move, it can drive the first support plate 1021 and the second support plate 1022 to start moving. When the first support plate 1021 and the second support plate 1022 start to move, the servo motor 201 and the rotating rod 204 can drive the rotating drum 102 to start moving. At the same time, the staff starts the servo motor 201 to operate, so that the servo motor 201 can drive the rotating rod 204 to rotate, thereby driving the rotating drum 102 to rotate.

[0045] Because a cavity is provided in the rotating rod 204 on one side of the second support plate 1022, and a fixing rod 202 is provided in the cavity, and the fixing rod 202 is fixedly connected to the second support plate 1022, the second support plate 1022 can only move horizontally and cannot rotate. When the rotating drum 102 rotates, it can drive the slide groove 2036 to rotate, thereby driving the slider 2037 to rotate. When the slider 2037 rotates, because it is fixedly connected to the positioning rod 2034 through the connecting rod 2038, it can drive the connecting rod 2038 and the positioning rod 2034 to rotate. At the same time, because one end of the positioning rod 2034 is set on the ball 2033, and the ball 2033 is rolled in the special-shaped slide groove 2032 provided on the first special-shaped rod 203 and the second special-shaped rod 2039, and because the special-shaped slide groove 2032 is composed of a semi-ring slide groove 203 When the first and second special-shaped rods 2039 are fixedly connected by the connecting rod 2031 and the fixing rod 202, the first special-shaped rod 203 and the second special-shaped rod 2039 are prevented from rotating. Therefore, the ball 2033 can move on the special-shaped groove 2032. When the ball 2033 moves to the side of the fixing rod 202, the ball 2033 can drive the positioning rod 2034 to be lifted. When the positioning rod 2034 is lifted, the piston plate 2035 can be lifted, so that the piston plate 2035 can leave the rectangular notch 1023 and enter the built-in cavity 1024. Therefore, the soil salinization and alkali remediation material in the built-in cavity 1024 can enter the rectangular notch 1023.

[0046] When the piston plate 2035 is lifted, it can drive the guide block 3011 to approach the outer wall of the drum 102 through the fixed block 301. Because the guide block 3011 is provided with an inclined surface 3012, the soil salinization and alkali remediation raw materials can be fed at a faster rate and then a slower rate, thereby achieving a relatively uniform feeding effect to a certain extent (because when the piston plate 2035 is lifted, the diameter of the hole in the rectangular notch 1023 where the soil salinization and alkali remediation raw materials enter increases from a small amount to a large amount);

[0047] When the guide block 3011 moves, it can drive the first movable plate 302 and the second movable plate 3027 to move horizontally with the assistance of the guide rod 3022 through the first movable rod 3024 and the second movable rod 3026. When the first movable plate 302 and the second movable plate 3027 move horizontally, they will be able to drive the telescopic rod 3023 to move, so that the first sealing plate 3025 and the second sealing plate 3028 can be driven by the telescopic rod 3023 to always move in contact with the outer wall of the rotating drum 102 with the assistance of the arc slide rail 303, thereby ensuring that the first sealing plate 3025 and the second sealing plate 3028 can be opened, so that the soil salinization remediation raw materials can be unloaded, and when the positioning rod 2034 is reset, the first sealing plate 3025 and the second sealing plate 3028 can be closed to achieve sealing, thereby ensuring that when the excavating blade 1025 loosens the soil, the soil contaminated above it will not enter the rectangular slot 1023 when it falls from a high place.
