Description

Technical Field

[0001] This invention relates to the field of seed coating technology, and more specifically to a seed coating liquid layered mixing and coating device. Background Technology

[0002] Seed coating technology is a crucial step in modern agricultural seed processing. By coating the surface of seeds with fungicides, insecticides, nutrients, growth regulators, and functional polymers, it can improve seed germination rate, disease and pest resistance, and seedling quality. Currently, seed coating typically uses roller or disc coating equipment, where a pre-mixed coating solution is sprayed onto the seed surface to complete the coating process.

[0003] For example, Chinese patent CN215500404U discloses a high-efficiency seed coating film forming device for high-quality corn seeds. This device includes: a barrel, a heating coil, a connecting screw, a movable rectangular frame, a spray pipe, a spray head, a temperature and humidity sensor, multiple rollers, a multi-layer support plate, a receiving tray, a seed coating mixing tank, a boiler, a display, and a dehumidifier. The heating coil is fitted onto the outer wall of the barrel; the inlet of the heating coil is connected to the outlet of the boiler; the outlet of the heating coil is connected to the inlet of the boiler; the dehumidifier is connected to the top and bottom surfaces of the barrel via a circulation pipe. This device can complete drying and seed coating agent coating within the barrel, and the coated material is discharged and transferred with minimal damage to the seed coating film. Furthermore, the seed coating film can protect the seeds, thereby reducing the proportion of seed damage and improving product quality. However, in practical application, this method is prone to sedimentation, stratification, local agglomeration, and uneven mixing because the coating solution often contains components with different densities, particle sizes, and chemical properties. Especially during long-term continuous operation, heavy particles tend to settle at the bottom of the container, while light components float on the upper layer, resulting in large fluctuations in the concentration of the sprayed coating solution. To solve the above problems, we propose a seed coating solution stratification mixing and coating device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a seed coating solution layered mixing and coating device, which solves the problem that the coating solution often contains components with different densities, particle sizes and chemical properties, which easily lead to sedimentation and stratification, local agglomeration and uneven mixing. Especially during long-term continuous operation, heavy particles tend to settle at the bottom of the container while light components float on the top, resulting in large fluctuations in the concentration of the sprayed coating solution.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A seed coating solution layered mixing and coating device, comprising: A placement platform, the top surface of which is provided with a coating tank, and the top surface of which is provided with a mixing tank; A dividing plate, which is fixedly connected to the inside of the mixing tank; Two rotating holes are respectively opened on the top and bottom surfaces of the coating tank, and rotating rods are rotatably installed inside the two rotating holes; Two connection holes are respectively opened on the bottom surface of the mixing tank and the top surface of the dividing plate. A control rod is rotatably installed inside the two connection holes, and the bottom end of the control rod is fixedly connected to the top end of the rotating rod. A feeding hole is provided on the top surface of the coating tank, and a discharge hole is provided on the bottom surface of the coating tank. A conveying component, which is disposed on the bottom surface of the mixing tank, is used to convey the liquid medicine; A stirring component is disposed on the outer wall surface of the rotating rod and is used to stir and mix the seeds.

[0006] Preferably, the conveying component includes: A conveying port is provided, which is located on the bottom surface inside the mixing tank, and a valve is fixedly connected inside the conveying port. A delivery pipe is fixedly connected to the bottom surface of the valve, and a liquid delivery hole is provided on the top surface of the coated tank. The delivery pipe is fixedly sleeved together with the liquid delivery hole. A dispersing element, disposed outside the rotating rod, is used to disperse the drug solution.

[0007] Preferably, the dispersing element comprises: A storage ring is fixedly connected to the outer wall of the rotating rod, and a partition ring is fixedly connected to the inner wall of the storage ring. Several liquid outlet holes are provided on the outer wall surface of the rotating rod.

[0008] Preferably, a protective cover is provided inside the discharge port, and positioning rods are fixedly connected to both sides of the protective cover. Positioning grooves are provided on both sides of the discharge port, and the positioning rods are movably sleeved with the positioning grooves. An observation hole is provided on the outer wall of the mixing tank, and a transparent plate is fixedly connected inside the observation hole.

[0009] Preferably, the stirring component includes: A plurality of stirring blades are fixedly connected to the outer wall of the rotating rod. A drive motor is fixedly connected to the bottom surface of the coating tank. The top end of the drive shaft of the drive motor is fixedly connected to the bottom surface of the rotating rod. A plurality of stirring blades, all of which are fixedly connected to the outer wall surface of the control rod; A conveyor, disposed on the top surface of the placement platform, is used to convey seeds.

[0010] Preferably, the conveying element includes: A placement trough is formed on the top surface of the placement platform, and a conveyor belt is provided inside the placement trough; Two rotating shafts are rotatably mounted inside the conveyor belt. Positioning holes are provided on both the left and right sides of the placement groove, and the rotating shafts are rotatably mounted together with the positioning holes.

[0011] Preferably, the top surface of the mixing container is provided with a protective cover, the bottom surface of the protective cover is provided with a rotating groove, a placement rod is rotatably installed inside the rotating groove, and several mixing plates are fixedly connected to the outer wall surface of the placement rod.

[0012] Preferably, the bottom surface of the placement rod has a limiting groove, the top end of the control rod is fixedly connected to a limiting block, the limiting block and the limiting groove are movably fitted together, a cover plate is movably installed inside the feeding hole, a stepper motor is fixedly connected to one side of the placement platform, one end of the drive shaft of the stepper motor is fixedly connected to one end of the rotating shaft, and a flow hole is opened on the top surface of the dividing plate, a sealing plug is movably installed inside the flow hole.

[0013] In summary, the present invention has the following main beneficial effects: By setting up a placement platform, the platform is first placed in a suitable position, and the coating solutions to be mixed are added separately into the mixing tank according to different functional requirements. The area formed by the dividing plate allows for the independent storage of the coating solution components, avoiding sedimentation and stratification after the components with different densities and properties are mixed in advance. With the mixing tank, when the valve is opened, the coating solution that has been stratified and mixed in the mixing tank is introduced into the coating tank through the delivery pipe. At the same time, the valve can be opened and closed according to the coating operation requirements to precisely control the total amount of solution entering the coating tank. When the rotating rod is rotating at high speed, the storage ring can rotate with the rotating rod. At this time, an annular buffer chamber can be formed inside the storage ring. Under the action of centrifugal force, the solution is evenly thrown out from each liquid outlet, and sprayed in a mist-like dispersion onto the surface of all seeds in the coating tank, preventing the solution from agglomerating and the concentration from exceeding the standard in some areas. By setting up a baffle ring, the baffle ring can block the solution inside the storage ring. By setting up a coating tank, the seeds inside the tank can flow out through the discharge hole. When the protective cover is installed inside the discharge hole, the protective cover blocks the discharge hole during the coating operation to prevent seeds from leaking out and the liquid from leaking out. After processing, the protective cover can be pulled out to unload the material. An observation hole is opened on the side wall of the mixing tank, so that the operator can directly observe the state of the liquid inside the mixing tank. By setting up a drive motor, when the drive shaft of the drive motor drives the rotating rod to rotate, the rotating rod can synchronously drive the control rod to rotate, so that the control rod drives the stirring blade on its outer wall to rotate synchronously. The stirring blade continuously stirs the liquid inside the mixing tank, so that the liquid components of different densities form a circulating flow state, reducing the deposition of heavy particles to the bottom and the floating of light components to the top, thereby improving the overall uniformity of the coating liquid. At the same time, the rotating rod can synchronously drive several stirring blades to rotate, thereby continuously turning the seeds inside the coating tank, so that each seed can fully contact the dispersed coating liquid. By setting up a conveyor belt, when the rotating shaft rotates, it can drive the conveyor belt to rotate; when the seeds inside the coating tank flow out through the discharge hole, the seeds can fall onto the conveyor belt under their own gravity, so that the conveyor belt can continuously transport the coated seeds. By setting up a cover plate, the cover plate can close the feeding hole at any time to interrupt the seed transport; by setting up a sealing plug, the sealing plug can control the flow of the liquid through the flow hole, so as to realize the layered mixing and blending of multiple coating components.
