[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention Embodiment

[0020] As Figures 1 to 8As shown in the figure, 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 cylinder 102. Four excavation blades 1025 are provided on the side wall of the rotating cylinder 102. An internal cavity 1024 is provided inside the rotating cylinder 102. Four rectangular notches 1023 are also provided on the side wall of the rotating cylinder 102 and are arranged in a circumferential distribution; the sealing unit 300 includes a plurality of first sealing plates 3025 and second sealing plates 3028. Each first sealing plate 3025 and second sealing plate 3028 are symmetrical to each other. Each first sealing plate 3025 and second sealing plate 3028 are respectively used to seal the outer wall of the rectangular notch 1023; the feeding unit 200 includes a servo motor 201, a driving component, and a piston plate 2035. The servo motor 201 is used to drive the rotating cylinder 102 to rotate. The driving component is used to drive the piston plate 2035 to move vertically. 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 rotating cylinder 102 rotates, it can drive the piston plate 2035 to lift with the assistance of the driving component. When the piston plate 2035 lifts, the soil saline-alkali restoration raw materials can be fed. Because when the piston plate 2035 rises, the aperture of the soil saline-alkali restoration raw materials entering the rectangular notch 1023 changes from small to large, that is, the amount of raw materials entering changes from less to more. At the same time, when the piston plate 2035 lifts, it will be able to drive the guide block 3011 to approach the outer wall of the rotating cylinder 102 through the fixing block 301. And because an inclined surface 3012 is provided on the guide block 3011, the soil saline-alkali restoration raw materials can change from a fast feeding speed to a slow feeding speed, and to a certain extent, the effect of relatively uniform feeding can be achieved.

[0021] As Figures 1 to 8 shown, in the specific implementation manner, rotating rods 204 are respectively provided on both side walls of the rotating cylinder 102. Second support plates 1022 and servo motors 201 are respectively provided at opposite ends of the two rotating rods 204. A first support plate 1021 is provided at one 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 rod 204. A cavity is provided inside the rotating rod 204. Installation brackets 101 are respectively provided at opposite ends of the first support plate 1021 and the second support plate 1022. In this setting, the installation and components on both sides of the rotating cylinder 102 are determined, ensuring that the rotating cylinder 102 can move. Embodiment

[0022] Based on Embodiment 1, the difference from this embodiment is: As Figures 1 to 8As shown in the figure, a saline-alkali land restoration device for promoting soil ecological balance, the driving assembly includes 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 semi-circular ring and a concave ring. The first special-shaped rod 203 and the second special-shaped rod 2039 are symmetrical to each other. A fixing rod 202 is arranged inside the first special-shaped rod 203 and the second special-shaped rod 2039. One end of the fixing rod 202 movably penetrates through the cavities opened on the rotating cylinder 102 and the rotating rod 204, and the port is fixedly connected to the second support plate 1022. In this setting, the installation position and components of the driving assembly are determined.

[0023] As Figures 6 to 8 shown, in the specific implementation manner, four connecting rods 2031 are fixedly connected to the inner cavities of both the first special-shaped rod 203 and the second special-shaped rod 2039. One end of each pair of opposite connecting rods 2031 is respectively connected to the fixing rod 202. Special-shaped sliding grooves 2032 are also opened on the outer side walls of the first special-shaped rod 203 and the second special-shaped rod 2039. In this setting, the connection relationship between the first special-shaped rod 203 and the second special-shaped rod 2039 and the fixing rod 202 is determined.

[0024] As Figures 6 to 8 shown, further, the special-shaped sliding groove 2032 includes a semi-circular ring sliding groove 20321 and a semi-circular concave sliding groove 20322. The semi-circular ring sliding groove 20321 and the semi-circular concave sliding groove 20322 communicate with each other. Four balls 2033 are slidably arranged on the semi-circular ring sliding groove 20321 and the semi-circular concave sliding groove 20322. Positioning rods 2034 are arranged on one side of the four balls 2033 away from the semi-circular ring sliding groove 20321 and the semi-circular concave sliding groove 20322 respectively. One end of each pair of opposite positioning rods 2034 is respectively connected with a piston plate 2035. Each piston plate 2035 respectively fits with the rectangular notch 1023. In this setting, the installation position of the piston plate 2035 is determined, ensuring that the plug plate 2035 can move. Embodiment

[0025] Based on Embodiment 2, the difference from this embodiment is: As Figures 6 to 8 shown, a saline-alkali land restoration device for promoting soil ecological balance, four sliding grooves 2036 arranged in a circumferential distribution are also opened on the opposite side walls of the inner cavity 1024 of the rotating cylinder 102. Each pair of the sliding grooves 2036 is symmetrical to each other. A slider 2037 is slidably arranged in each inner cavity of the sliding grooves 2036. One end of each slider 2037 away from the sliding groove 2036 is provided with a connecting rod 2038. The other end of each connecting rod 2038 is respectively arranged on the positioning rod 2034. In this setting, the installation position and components of the connecting rod 2038 are determined.

[0026] As Figures 1 to 8As shown, in the specific implementation, a fixing block 301 is fixedly connected to one side wall of each of the four piston plates 2035 away from the built-in cavity 1024. A guiding block 3011 is fixedly connected to one end of each of the four fixing blocks 301 away from the piston plate 2035. Inclined surfaces 3012 are formed on both sides above the four guiding blocks 3011. In this setting, it is ensured that when the piston plate 2035 is lifted, the guiding block 3011 can be driven by the fixing block 301 to approach the outer wall of the rotating cylinder 102. Since the inclined surfaces 3012 are formed on the guiding block 3011, the soil salinity repair raw materials can have a decreasing feeding speed, and to a certain extent, a relatively uniform feeding effect can be achieved.

[0027] As Figures 1 to 8 shown, further, two first movable rods 3024 and two second movable rods 3026 are respectively arranged on both sides of each of the four guiding blocks 3011. A first moving plate 302 is movably connected between every two of the first movable rods 3024. A second moving plate 3027 is movably connected to one end of every two of the second movable rods 3026 that are opposite to each other. In this setting, when the guiding block 3011 moves, it can drive the first moving plate 302 and the second moving plate 3027 to horizontally move with the assistance of the guiding rods 3022 through the first movable rods 3024 and the second movable rods 3026 respectively.

[0028] As Figures 1 to 8 shown, further, a fixing plate 3021 is arranged on the opposite side of each of the first moving plates 302 and the second moving plates 3027. Each fixing plate 3021 is arranged on the rotating cylinder 102. Guiding rods 3022 are arranged on the opposite sides of each pair of the fixing plates 3021. Each pair of the guiding rods 3022 movably penetrates through the first moving plate 302 and the second moving plate 3027 respectively. In this setting, it is ensured that the first moving plate 302 and the second moving plate 3027 can horizontally move.

[0029] As Figures 1 to 8As shown in the figure, further, a telescopic rod 3023 is provided above each first moving plate 302 and second moving 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 second sealing plate 3028 and the rotary drum 102, and each arc-shaped slide rail 303 is arranged on the rotary drum 102. In this setting, it is ensured that when the first moving plate 302 and the second moving plate 3027 move horizontally, they will be able to drive the telescopic rod 3023 to move. Thus, the first sealing plate 3025 and the second sealing plate 3028 can be respectively driven by the telescopic rod 3023 to move along the outer wall of the rotary drum 102 with the assistance of the arc-shaped slide rail 303. Therefore, it is ensured that the first sealing plate 3025 and the second sealing plate 3028 can be opened, so that the soil salinity repair raw materials can be fed. When the positioning rod 2034 is reset, at this time, the first sealing plate 3025 and the second sealing plate 3028 can be closed to achieve sealing. Therefore, it is ensured that when the digging edge 1025 loosens the soil, the soil contaminated above it will not enter the rectangular notch 1023 when it falls from a high place.

[0030] The implementation principle of a saline-alkali land restoration device for promoting soil ecological balance of the present invention is as follows: First, the staff drives the mounting bracket 101 to move through existing mechanical equipment. When the mounting bracket 101 starts to move, it will be able to drive the first support plate 1021 and the second support plate 1022 to move. When the first support plate 1021 and the second support plate 1022 start to move, they will be able to drive the rotary drum 102 to move through the servo motor 201 and the rotating rod 204. At the same time, the staff starts the servo motor 201 to operate. Therefore, the servo motor 201 will be able to drive the rotating rod 204 to rotate, thereby driving the rotary drum 102 to rotate; Since a cavity is formed inside the rotating rod 204 on one side of the second support plate 1022, and a fixed rod 202 is arranged inside the cavity, and the fixed rod 202 is fixedly connected to the second support plate 1022, the second support plate 1022 can only move horizontally and will not rotate. When the rotating cylinder 102 rotates, it can drive the sliding groove 2036 to rotate, thereby driving the slider 2037 to rotate. When the slider 2037 rotates, since 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, since one end of the positioning rod 2034 is arranged on the ball 2033, and the ball 2033 is arranged to roll inside the special-shaped sliding groove 2032 formed on the first special-shaped rod 203 and the second special-shaped rod 2039, and since the special-shaped sliding groove 2032 is composed of a semi-circular ring sliding groove 20321 and a semi-circular concave sliding groove 20322, and the first special-shaped rod 203 and the second special-shaped rod 2039 are fixedly connected through the connecting rod 2031 and the fixed rod 202, it is ensured that the first special-shaped rod 203 and the second special-shaped rod 2039 will not rotate. Therefore, the ball 2033 can move on the special-shaped sliding groove 2032. When it moves to the semi-circular concave sliding groove 20322, the running track of the ball 2033 moves closer to the side of the fixed rod 202 at this time, so that the ball 2033 can drive the positioning rod 2034 to lift. When the positioning rod 2034 lifts, it can drive the piston plate 2035 to lift, so that the piston plate 2035 can leave the rectangular notch 1023 and enter the built-in cavity 1024. Therefore, the soil salinity repair raw materials in the built-in cavity 1024 can enter the rectangular notch 1023; When the piston plate 2035 lifts, it can drive the guide block 3011 to approach the outer wall of the rotating cylinder 102 through the fixed block 301. Since an inclined surface 3012 is formed on the guide block 3011, the soil salinity repair raw materials can change from a fast feeding speed to a slow feeding speed, and to a certain extent, a relatively uniform feeding effect can be achieved (because when the piston plate 2035 rises, the aperture for the soil salinity repair raw materials to enter the rectangular notch 1023 changes from small to large, that is, the amount of the entering raw materials changes from less to more); When the guiding block 3011 moves, it can drive the first moving plate 302 and the second moving plate 3027 to move horizontally with the assistance of the guiding rod 3022 through the first movable rod 3024 and the second movable rod 3026 respectively. When the first moving plate 302 and the second moving plate 3027 move horizontally, they will be able to drive the telescopic rod 3023 to move. Thus, the first sealing plate 3025 and the second sealing plate 3028 can be driven by the telescopic rod 3023 to always move while being attached to the outer wall of the rotary drum 102 with the assistance of the arc-shaped slide rail 303. Therefore, it is ensured that the first sealing plate 3025 and the second sealing plate 3028 can be opened, so that the soil salinity repair raw materials can be fed. When the positioning rod 2034 resets, at this time the first sealing plate 3025 and the second sealing plate 3028 can be closed, thus realizing sealing. Therefore, it is ensured that when the excavation edge 1025 loosens the soil, the soil contaminated above it will not enter the rectangular notch 1023 when it falls from a height.
