Description

Technical Field

[0001] This invention belongs to the field of fertilizer ratio application technology, specifically relating to an automatic ratio application device for organic fertilizer and chemical fertilizer. Background Technology

[0002] Liquid organic fertilizers, such as biogas slurry, originate from the anaerobic fermentation of organic waste such as livestock and poultry manure. This transformation process not only reduces environmental pollution but also produces fertilizers that can be used in agriculture. Using liquid organic fertilizers helps improve soil structure and crop quality while reducing the use of chemical fertilizers and minimizing environmental impact. In the transformation and upgrading of grassland animal husbandry, the use of liquid organic fertilizers contributes to grassland ecological restoration and vegetation recovery.

[0003] Unlike solid fertilizers, liquid fertilizers used in fertigation are formulated with carefully designed nutrient components based on the specific plants being fertilized. The ratio of these liquid fertilizer components varies at different stages of growth. Currently, manually mixing these components is not only labor-intensive but also prone to errors that can lead to discrepancies in the proportions of different fertilizer components. Therefore, we propose an automated organic and chemical fertilizer mixing and application device to address these issues. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the current method of manually mixing fertilizers is not only labor-intensive, but also prone to errors that could lead to deviations in the proportions of different fertilizer components.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] An automatic organic fertilizer and chemical fertilizer mixing and application device includes a base plate, a mixing tank fixedly installed on the upper part of the base plate, and a delivery pump. The input end of the delivery pump is connected to the lower part of the mixing tank, and the output end of the delivery pump is fixedly connected to a fertilizer application pipe. A fixing frame is provided at the upper end of the mixing tank. A cylinder and multiple fixing cylinders are fixedly installed on the fixing frame. A fixing plate is fixedly installed at the upper end of the cylinder, and multiple compression springs are fixedly installed at the lower end of the fixing plate. A first movable plug and a second movable plug are movably installed inside each of the multiple fixing cylinders. A pull rope is fixedly connected between the fixing plate and the first movable plug. The lower ends of the multiple compression springs are respectively fixedly connected to the first movable plugs inside the multiple fixing cylinders. The inner walls of the multiple fixing cylinders are fixed near the upper end. A protruding post is fixedly installed, and a limiting rod is fixedly installed between the lower end of the protruding post and the bottom of the inner wall of the fixed cylinder. The limiting rod passes through the first movable plug and the second movable plug. Both the first and second movable plugs are provided with elastic rubber rings at the points through which the limiting rod passes. The lower part of the multiple fixed cylinders is provided with an adjustment component that can drive the second movable plug to move within the fixed cylinder. The lower end of the second movable plug is provided with a feed pipe and a discharge pipe. The cylinder wall of the fixed cylinder is provided with a capacity mark. The lower end of the fixed cylinder has an opening through which the feed pipe and the discharge pipe pass. The feed pipe and the discharge pipe are respectively provided with a first one-way valve and a second one-way valve at their connection points with the fixed cylinder. The end of the feed pipe is connected to the fertilizer supply, and the lower end of the discharge pipe extends into the mixing tank.

[0007] Further specifying, the adjusting assembly includes a threaded post and a rotating knob. The bottom center of the fixed cylinder has a threaded groove, and the threaded post is threadedly connected to the fixed cylinder through the threaded groove. The upper end of the threaded post has an adapter groove, and the lower end of the second movable plug is fixedly fitted with an adapter post adapted to the adapter groove. The threaded post is rotatably connected to the second movable plug, and the rotating knob is fixedly installed at the lower end of the threaded post. This structural design allows the second movable plug to move vertically up and down under the limiting action of a limiting rod by rotating the threaded post with the knob, thereby adjusting the distance between the first and second movable plugs to adjust the capacity of the fixed cylinder.

[0008] Furthermore, a fixed platform is fixedly installed on the upper end of the mixing tank, and the upper end of the fixed platform is fixedly connected to the lower end of the fixed frame. A through hole is provided on the fixed platform corresponding to the discharge pipe. This structural design increases the distance between the fixed frame and the top of the mixing tank through the fixed platform, thereby providing sufficient adjustment space for the adjustment components and making it more convenient to use.

[0009] Further specifying, multiple aeration components are provided between the fixed disc and the fixed frame. Each aeration component includes an air storage cylinder, a piston, a pressure rod, a third one-way valve, and an air outlet pipe. The air storage cylinder is fixedly installed at the upper end of the fixed frame. The piston is movably installed inside the air storage cylinder. The pressure rod is fixedly installed on the piston, with its upper end penetrating the upper end of the air storage cylinder and fixedly connected to the lower end of the fixed disc. The third one-way valve is fixedly inserted into the lower part of the air storage cylinder. The air outlet pipe is fixedly inserted into the bottom of the air storage cylinder, with its lower end penetrating the fixed frame and the fixed platform, extending into the mixing tank. This structural design allows the pressure rod and piston to move downwards when the fixed disc moves downwards, forcing air from the air storage cylinder into the mixing tank through the air outlet pipe, creating an aeration effect and ensuring uniform mixing of water and fertilizer.

[0010] Furthermore, the lower ends of both the air outlet pipe and the material outlet pipe are close to the bottom of the inner wall of the mixing tank. The lower end of the air outlet pipe is curved, and its opening faces the adjacent material outlet pipe. This structural design, with the air outlet pipe opening curved towards the material outlet pipe, can agitate the fertilizer immediately when it is discharged from the material outlet pipe, thus enhancing the mixing effect.

[0011] Furthermore, the upper end of the mixing tank is fixedly connected to a connector post, and the connector post has several vent holes. This structural design allows the vent holes to balance the air pressure inside and outside the mixing tank, preventing excessive air pressure inside the mixing tank from causing fertilizer to be unable to be fed in.

[0012] The invention employing the above technical solution has the following advantages:

[0013] This invention allows for the automatic mixing of fertilizers in different proportions. When mixing fertilizers, the position of the second movable plug within the fixed cylinder is adjusted using an adjusting component, thereby adjusting the capacity of each fixed cylinder. When the cylinder extends, the first movable plug can be pulled upwards via a pull rope, simultaneously drawing in liquid fertilizers of different volumes. When the cylinder retracts, the liquid fertilizers of different volumes are squeezed into the mixing tank via a compression spring. This invention automatically completes the mixing of fertilizers in different proportions, making it convenient to use and improving fertilizer mixing efficiency. Attached Figure Description

The lower end of the second movable plug 422 is fixedly installed with a transition post that matches the transition groove. The threaded post 43 is rotatably connected to the second movable plug 422. When the threaded post 43 rotates, it can push the second movable plug 422 to move inside the fixed cylinder 42 to adjust the distance between the second movable plug 422 and the first movable plug 421, so as to facilitate the adjustment of the volume at the fixed cylinder 42, so that different volumes of fertilizer can be accommodated in different fixed cylinders 42. The rotary knob 431 is fixedly installed at the lower end of the threaded post 43.

[0038] Multiple aeration components are provided between the fixed plate 411 and the fixed frame 4. The aeration components include an air storage cylinder 5, a piston 51, a pressure rod 52, a third one-way valve 53, and an air outlet pipe 54. The air storage cylinder 5 is fixedly installed on the upper end of the fixed frame 4. The piston 51 is movably installed inside the air storage cylinder 5. The pressure rod 52 is fixedly installed on the piston 51.

[0039] The lower ends of both the vent pipe 54 and the discharge pipe 4212 are close to the bottom of the inner wall of the mixing tank 2. The lower end of the vent pipe 54 is curved and the pipe opening faces the adjacent discharge pipe 4212. The upper end of the mixing tank 2 is fixedly connected to the insertion post 22. Several vent holes are opened on the insertion post 22. The vent holes can ensure the air circulation inside and outside the mixing tank 2, so as to avoid excessive air pressure inside the mixing tank 2, which would affect the injection of fertilizer.

[0040] The method of using this invention is as follows:

[0041] In use, select the required number of fixed cylinders 42 as needed, connect the feed pipes 4211 on each fixed cylinder 42 to the fertilizer supply end, and rotate the threaded column 43 by turning the knob 431 to drive the second movable plug 422 to move under the limiting action of the limiting rod 424, so as to adjust the distance between the second movable plug 422 and the first movable plug 421 (at this time, the cylinder 41 is in the extended limit state). After the distance adjustment is completed, the cylinder 41 retracts, driving the fixed plate 411 to move downward, and pushing the first movable plug 421 downward through the compression spring 412. The plug 421 squeezes out the excess air between the second movable plug 422 and the first movable plug 421, and the cylinder 41 extends again. The fixed plate 411, together with the pull rope 413, drives the first movable plug 421 to move upward. The fertilizer is introduced into the fixed cylinder 42 through the feed pipe 4211 and the first one-way valve. When the cylinder 41 reaches the extension limit, the cylinder 41 retracts again, squeezing the fertilizer inside the fixed cylinder 42 into the mixing tank 2 through the discharge pipe 4212. Fertilizers of different volumes in each fixed cylinder 42 can be squeezed into the mixing tank 2 at the same time to complete the mixing ratio.

[0042] When the cylinder 41 contracts and the fertilizer is squeezed out of the fixed cylinder 42, the downward moving fixed plate 411 will also drive the piston 51 through the pressure rod 52 to squeeze the air in the air storage cylinder 5 and output it outward through the air outlet pipe 54. When the fertilizer is output from the discharge pipe 4212, it can disturb the fertilizer at the first time, which produces an aeration effect and enhances the mixing effect.

[0043] The above provides a detailed description of an automatic organic fertilizer and chemical fertilizer mixing and application device provided by the present invention. The specific embodiments described are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
