[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] A device for applying a microbial amendment for soil improvement includes a microbial agent adding component 3, which is arranged on a support member 2. The support member 2 is fixed to one side of a connecting frame 1. There are several microbial agent adding components 3, each of which is fixedly connected to one support member 2. The microbial agent adding components 3 are used for adding microbial agents.

[0017] In this embodiment, multiple microbial reagent adding components 3 are used to independently add multiple groups of microbial reagents, and reagent combinations can be prepared according to different soil requirements.

[0018] Furthermore, the support member 2 is provided with a soil-breaking component 21 at one end close to the connecting frame 1, and a flattening wheel 22 is rotatably provided at the other end of the support member 2. The microbial reagent adding component 3 is arranged between the soil-breaking component 21 and the flattening wheel 22. The connecting frame 1 is connected to a movable vehicle body. When moving, the vehicle body drives the soil-breaking component 21 to break the soil, the microbial reagent adding component 3 adds reagent, and the flattening wheel 22 performs flattening.

[0019] The microbial reagent adding component 3 includes a reagent storage tank 31, a support plate 32, a connecting column 33, a driving member 34, a fixed plate 35, a protective cover 36, a cylinder 37, a cam turntable 38 and a liquid outlet pipe 39. There are several chicken storage tanks and they are all fixed on the support plate 32. The support plate 32 is fixedly connected to the fixed plate 35 through the connecting column 33. The upper side of the fixed plate 35 is fixedly connected to a group of cylinders 37 evenly arranged around the circumference. The upper end of the cylinder 37 is fixedly connected to a fixing ring 371. The fixed ring 371 is connected to the cam disc 38 through the driving member 34. The cam disc 38 includes a circular plate and an arc-shaped protrusion fixed on the circular plate. The arc-shaped protrusion occupies half of the range of the circular plate. The upper surface of the arc-shaped protrusion is smoothly connected to the upper surface of the circular plate. A plurality of evenly arranged rollers 381 are provided on the upper side of the cam disc 38. Each of the rollers 381 is respectively connected to the roller bracket 382. The lower side of one end of the roller bracket 382 is fixedly connected to the guide column 383. The guide column 383 is fixed to the guide column 383. The lower end of the extension rod 384 is fixedly connected to the lower end of the extension rod 384, and a bellows 392 is fixedly provided at the lower end of the bellows 392. A spray hole 393 is opened at the lower end of the bellows 392. The upper end of the bellows 392 is fixedly connected to the liquid outlet pipe 39. The upper end of the liquid outlet pipe 39 passes through the lower end of the reagent storage tank 31. The liquid outlet pipe 39 and the reagent storage tank 31 are sealed. The liquid outlet pipe 39 and the guide column 383 both pass through the opening 351 opened on the fixed plate 35. The guide column 383 slides The limit rod 372 is dynamically connected and fixedly connected to the cylinder 37. The upper end of the liquid outlet pipe 39 is arranged in the reagent storage tank 31. When the roller 381 is in contact with the lowest point on the upper side of the cam turntable 38, the upper end of the liquid outlet pipe 39 is at the bottom end of the reagent storage tank 31. When the roller 381 is in contact with the highest point on the upper side of the cam turntable 38, the upper end of the liquid outlet pipe 39 is higher than the height of the liquid level in the reagent storage tank 31, and the reagent will not enter from the liquid outlet pipe 39.

[0020] In this embodiment, the driving member 34 is used to drive the cam turntable 38 to rotate. The cam turntable 38 controls the up and down movement of the extension rod 384 and the bellows 392 through the roller 381, the roller bracket 382, the guide column 383 and other components, thereby controlling the position of the liquid outlet pipe 39 in the reagent storage tank 31, realizing the control of the reagent absorption and stopping of absorption, and ensuring that the device can intermittently spray the microbial reagent.

[0021] The protective cover 36 is fixedly provided on the lower side of the fixed plate 35, and the bellows 392 is provided in the protective cover 36. The protective cover 36 is fixedly provided with symmetrical fixed extrusions corresponding to the lower side position of each bellows 392. When the bellows 392 follows the extension rod 384 and the guide column 383 to move downward, the bellows 392 is squeezed, so that the reagent liquid inside the bellows 392 is sprayed out from the spray hole 393 under the action of the squeezing force.

[0022] The protective cover 36 is a diamond-shaped cover with sharp front and rear ends, and its two ends are respectively arranged corresponding to the two ends of the support member 2.

[0023] In this embodiment, when the bellows 392 moves downward following the extension rod 384 and the guide column 383, the fixed extrusion block in the protective cover 36 will squeeze the bellows 392, so that the reagent liquid in the bellows 392 is ejected from the spray hole 393 under the action of the extrusion force, thereby ensuring that the reagent can be ejected from the bellows 392 through mechanical extrusion.

[0024] The driving member 34 includes a first rotating wheel 341, a belt 342, a second rotating wheel 343 and a motor 344. The first rotating wheel 341 is connected to the second rotating wheel 343 through the belt 342. The second rotating wheel 343 is fixed on the lower side of the cam turntable 38. The center of the first rotating wheel 341 is fixedly connected to the output shaft of the motor 344. The motor 344 is fixedly connected to the upper side of one end of the fixed plate 35.

[0025] In this embodiment, the motor 344 drives the first rotating wheel 341 to rotate, and the first rotating wheel 341 drives the second rotating wheel 343 through the belt 342, thereby driving the cam rotating disk 38 fixed on the second rotating wheel 343 to rotate, so that the cam rotating disk 38 can lift different rollers 381.

[0026] The liquid outlet pipe 39 is connected to the bellows 392 via a one-way valve 391 . The one-way valve 391 only allows the reagent to enter the bellows 392 from the liquid outlet pipe 39 , and does not allow the reagent to enter the liquid outlet pipe 39 from the bellows 392 .

[0027] In this embodiment, the setting of the one-way valve 391 only allows the reagent to enter the bellows 392 from the liquid outlet pipe 39, preventing the reagent from flowing back from the bellows 392 into the liquid outlet pipe 39, ensuring the unidirectional flow of the reagent, avoiding the backflow of the reagent, and ensuring the normal flow and use of the reagent.

[0028] Each of the reagent storage tanks 31 is equipped with an upper cover, which is mainly used to prevent foreign matter from entering the reagent storage tank 31, thereby ensuring the purity of the reagent, protecting the reagent from contamination, and ensuring the quality of the microbial reagent, thereby ensuring the soil improvement effect.

[0029] The bottom of the reagent storage tank 31 is respectively provided with a drain valve. The drain valve is provided at the bottom of the reagent storage tank 31 to facilitate the discharge of the reagent in the storage tank after use, and to facilitate cleaning and maintenance of the reagent storage tank 31.

[0030] A toggle block 385 is fixedly mounted on one side of the extension rod 384 corresponding to the protective cover 36. A fixed shaft 362 is fixedly mounted inside the protective cover 36 corresponding to each toggle block 385. The extension rod 384 is a rubber rod with a certain degree of elasticity. When the toggle block 385 moves vertically with the guide post 383 and the extension rod 384, the fixed shaft 362 causes the toggle block 385 to swing, thereby driving the bellows 392 to vibrate, achieving swing spraying when spraying the reagent. As the toggle block 385 on the extension rod 384 moves vertically with the guide post 383 and the extension rod 384, it is toggled by the fixed shaft 362 inside the protective cover 36, causing it to swing, which in turn drives the bellows 392 to vibrate, achieving swing spraying. This makes the spraying of the reagent more uniform and expands the spraying range of the reagent.

[0031] In this embodiment, each of the microbial reagent adding components 3 has n reagent storage tanks 31, wherein n-1 reagent storage tanks 31 contain solutions of soil additives such as different microbial improvers, one of which is water, to facilitate better and more uniform mixing of the additive solution and the soil. The number of the reagent storage tanks 31 is preferably 4.

[0032] In another embodiment, a toggle block 385 is fixedly provided on one side of the extending rod 384 corresponding to the protective cover 36, and a fixed shaft 362 is fixedly provided inside the protective cover 36 corresponding to each toggle block 385. The extending rod 384 is a rubber rod with a certain elasticity. When the toggle block 385 moves vertically following the guide column 383 and the extending rod 384, the fixed shaft 362 can cause the toggle block 385 to swing, thereby driving the bellows 392 to vibrate, thereby realizing swing spraying when spraying the reagent.

[0033] The method of use of the present invention is: Open the top cover of the reagent storage tank 31 and add different solutions of soil additives such as microbial improvers into each reagent storage tank 31. Add water into one reagent storage tank 31. Preferably, four reagent storage tanks 31 are provided. Close the top cover to ensure a seal to prevent impurities from entering. Fix the support member 2 to one side of the connecting frame 1 to ensure that the microbial reagent adding component 3 is firmly installed. The connecting frame 1 can be installed on the movable frame; the movement of the frame drives the microbial reagent adding component 3 to move; The motor 344 is started, and the motor 344 drives the first rotating wheel 341 to rotate, and the second rotating wheel 343 drives the cam rotary disk 38 to rotate through the belt 342. During the rotation of the cam rotary disk 38, different rollers 381 are lifted up, and the rollers 381 drive the guide column 383 and the extension rod 384 to move up and down through the roller bracket 382, thereby controlling the position of the liquid outlet pipe 39 in the reagent storage tank 31. When the roller 381 is in contact with the highest point on the upper side of the cam rotary disk 38, the liquid outlet pipe 39 is above the liquid level, and the reagent will not enter the liquid outlet pipe 39. As the highest point on the upper side of the rotary disk 38 gradually moves to the lowest point, the liquid outlet pipe 39 gradually drops below the liquid level, and the reagent enters the liquid outlet pipe 39, passes through the one-way valve 391, and enters the bellows 392. As the extension rod 384 and the guide column 383 move downward, the bellows 392 follows and moves downward until it contacts the upper side of the fixed extrusion block. Since the fixed extrusion block is stationary, the bellows 392 continues to move downward with the extension rod 384 and is squeezed by the fixed extrusion block. The reagent liquid inside is ejected from the spray hole 393 under the action of the squeezing force. When the soil conditioner application is completed, the motor 344 is turned off. The remaining reagent is discharged through the drain valve at the bottom of the reagent storage tank 31, and the upper cover is opened to clean the reagent storage tank 31 for the next use.

[0034] In another embodiment, when the toggle block 385 on the extension rod 384 follows the vertical movement, it passes through the fixed shaft 362 in the protective cover 36. Since the fixed shaft 362 is stationary, the toggle block 385 is fixedly connected to the elastic extension rod 384. Under the blocking effect of the fixed shaft 362, the toggle block 385 drives the extension rod 384 to swing, driving the bellows 392 to vibrate, achieving swing spraying and evenly applying the agent to the soil. The above disclosure is only a specific embodiment of the present invention, but the present invention is not limited to this. Any changes that can be thought of by those skilled in the art should fall within the scope of protection of the present invention.
