Technical Field

[0001] This utility model relates to the field of seed treatment technology, and in particular to a high-efficiency mixing and coating machinery for coating oat seeds for feed. Background Technology

[0002] Continuous coating machines can process multiple types of seeds continuously. Through feeding, mixing, and drying processes, combined with intelligent control, they achieve efficient coating, improving seed processing efficiency and quality. These continuous coating machines typically use atomizing nozzles to spray the coating solution.

[0003] In continuous seed coating operations, the core cause of atomizing nozzle blockage is the dynamic sedimentation of micro-fertilizer particles and binders in the coating agent due to density differences. This leads to the continuous accumulation of high-concentration suspended matter on the inner wall of the nozzle, resulting in a reduction in the effective passage diameter until complete blockage. Utility Model Content

[0004] Therefore, it is necessary to provide a high-efficiency mixing and coating machinery for the coating treatment of feed oat seeds to address the problem that the dynamic sedimentation of micronutrients and binders in the coating agent causes the atomizing nozzles to become clogged, resulting in a continuous reduction and eventual blockage of the effective nozzle diameter in continuous coating machines.

[0005] A high-efficiency mixing and coating mechanical device for coating oat seeds for feed includes: a horizontal mixer, a stirring sprayer, and a detachable spraying mechanism. The stirring sprayer is disposed on one side of the horizontal mixer, and a liquid guide pipe is fixedly connected to the liquid outlet end of the stirring sprayer.

[0006] In one embodiment, the detachable spraying mechanism includes a plug fixedly connected to the surface of the liquid guide tube. The bottom of the plug extends through the interior of the horizontal agitator housing. The bottom of the plug is threadedly connected to an atomizing nozzle that communicates with the liquid guide tube. A positioning ring is fixedly connected to the inner side of the atomizing nozzle. A filter screen is placed on the top of the positioning ring. The vertical cross-section of the filter screen is inverted V-shaped.

[0007] In one embodiment, the detachable spraying mechanism includes a connecting cylinder placed on top of a positioning ring, the filter screen being fixedly connected to the inside of the connecting cylinder, and guide blades being fixedly connected inside the connecting cylinder.

[0008] In one embodiment, the guide vane is in the shape of a cross-shaped spiral, and the bottom of the guide vane is fixedly connected to the filter screen.

[0009] In one embodiment, the vertical cross-sectional shape of the top of the guide vane is an isosceles triangle, and the inner opening of the connecting cylinder is beveled.

[0010] In one embodiment, a ball bearing is embedded in the bottom of the connecting cylinder, and the circular dot of the ball bearing is located inside the connecting cylinder.

[0011] In one embodiment, the number of balls is not less than ten, and the balls are arranged in a ring around the axis of the connecting cylinder.

[0012] In one embodiment, the surface of the connecting cylinder is provided with an annular groove, and a sealing ring that contacts the atomizing nozzle is embedded inside the annular groove.

[0013] In one embodiment, the sealing ring is O-shaped and is a fluororubber material component.

[0014] Beneficial effects

[0015] 1. The aforementioned high-efficiency mixing and coating machinery for treating feed oat seeds features a detachable spraying mechanism that allows for independent replacement or cleaning via threaded connections of the atomizing nozzles. As the final atomization actuator, it reliably atomizes the homogenized solution into tiny droplets suitable for coating. The mechanism's unique inverted V-shaped filter design increases the effective filtration area, efficiently intercepting larger particles and clumps in the solution, preventing them from directly clogging the downstream flow channel, and simultaneously guiding the solution towards the center.

[0016] 2. The detachable spraying mechanism features a detachable design, allowing for quick removal of components for direct and thorough cleaning or replacement when maintenance is needed, significantly reducing downtime and maintenance costs.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The following is combined with Figure 1 - Figure 5 This invention describes a highly efficient mixing and coating machinery for treating feed oat seeds.

[0027] In one embodiment, a high-efficiency mixing and coating machinery for coating oat seeds for feed includes: a horizontal mixer 100, a stirring sprayer 200, and a detachable spraying mechanism 400. The stirring sprayer 200 is disposed on one side of the horizontal mixer 100, and a liquid guide pipe 300 is fixedly connected to the liquid outlet end of the stirring sprayer 200.

[0028] The horizontal mixer 100 is the core unit for mixing seeds and coating agents. Its main structure is a sealed stainless steel horizontal cylinder, internally equipped with multiple sets of staggered blades driven by a motor and reducer. During operation, these blades generate strong convection and diffusion motion in the material, creating an ideal "boiling" fluidization state, providing a uniform contact and coating surface for the atomized droplets. Its operating process is as follows: after adding oat seeds, dry mixing is initiated, followed by receiving coating agents from the spray system while maintaining operation. After efficient coating, the finished product is discharged. It is not a standard model, but its design can be referenced from industrial models such as the WZ series zero-gravity mixer, and customized according to capacity.

[0029] The stirred sprayer 200 is a pesticide supply system specifically designed for coating operations. Its core is a stainless steel mixing tank with a top-mounted mechanical agitator. It does not contain a spray terminal; its function is to ensure uniform concentration and no sedimentation of the coating pesticide solution within the tank through continuous agitation, and to provide a stable liquid source to the system via an external pump. During operation, it first performs pre-stirring to ensure uniform mixing of the pesticide solution. During production, its agitator continues to operate, and the pesticide solution is drawn from the bottom of the tank by a diaphragm pump and delivered to the atomizing nozzle 420 through the liquid guide pipe 300. As a power source and supply station, it ensures the uniformity and stability of the pesticide solution during the spraying phase.

[0030] like Figure 3 , Figure 4 and Figure 5 As shown, the detachable spraying mechanism 400 includes a plug 410 fixedly connected to the surface of the liquid guide tube 300. This plug 410 provides a secure connection between the liquid guide tube 300 and the spraying mechanism, allowing for quick disassembly and assembly, thus providing a basis for overall maintenance. The bottom of the plug 410 extends into the housing of the horizontal agitator 100. A threaded connection is made to the bottom of the plug 410 to an atomizing nozzle 420 that communicates with the liquid guide tube 300. As the final atomization actuator, its threaded connection facilitates independent replacement or cleaning. Its core function is to reliably atomize the homogenized liquid into suitable coated micro-droplets. A positioning ring 430 is fixedly connected to the inner side of the atomizing nozzle 420, providing a precise installation positioning reference for components such as the connecting cylinder 450 and the filter screen 440 above, ensuring coaxiality and assembly stability among the components. A filter screen 440 is placed on top of the positioning ring 430. The vertical cross-section of the filter screen 440 is inverted V-shaped. This unique design increases the effective filtration area to efficiently intercept larger particles and initially formed clumps in the liquid, serving as the first line of defense to prevent them from directly clogging the downstream flow channel. At the same time, this shape helps guide the liquid to flow towards the center.

[0031] like Figure 4 and Figure 5As shown, the detachable spraying mechanism 400 also includes a connecting cylinder 450 placed on top of the positioning ring 430, serving as the core flow channel carrier. Its inner opening has a beveled angle, effectively reducing resistance and turbulence during liquid inflow and achieving a smooth streamline transition. A filter screen 440 is fixedly connected to the inner side of the connecting cylinder 450. A guide vane 460 is fixedly connected inside the connecting cylinder 450. This vane efficiently converts the linear flow of the liquid into a high-speed rotating vortex. The guide vane 460 is shaped like a cross-shaped spiral. The centrifugal force generated by the rotation causes the high-density micro-fertilizer particles to be thrown towards the outer edge of the flow channel and fully mixed with the liquid, thus actively preventing dynamic sedimentation and stratification of particles during transport and ensuring the uniformity of the liquid concentration. The bottom of the guide vane 460 is fixedly connected to the filter screen 440. The vertical cross-sectional shape of the top of the guide vane 460 is an isosceles triangle. This streamlined design effectively reduces resistance during liquid passage, minimizes vortex energy loss, and makes fluid flow smoother.

[0032] like Figure 4 and Figure 5 As shown, a ball bearing 470 is embedded in the bottom of the connecting cylinder 450, with the circular point of the ball bearing 470 located inside the connecting cylinder 450. There are at least ten balls bearing 470, arranged in a ring around the axis of the connecting cylinder 450. These balls bearing 470 convert the macroscopic vibrations during equipment operation into uniform high-frequency micro-vibrations and transmit them throughout the entire interior of the connecting cylinder 450. This continuous micro-vibration makes it difficult for particles to adhere stably to the filter screen 440 and the cylinder wall of the connecting cylinder 450, effectively preventing the filter screen 440 pores from being blocked and particles from depositing and scaling on the flow channel surface, thus maintaining continuous unobstructed flow. An annular groove 451 is formed on the surface of the connecting cylinder 450, and a sealing ring 480 that contacts the atomizing nozzle 420 is embedded inside the annular groove 451. The sealing ring 480 is O-shaped and made of fluororubber. Utilizing the excellent chemical resistance and high elasticity of fluororubber, it forms a reliable seal at the connection point, completely preventing liquid leakage and the formation of dried solids that could clog the nozzle or contaminate the equipment, thus greatly improving operational reliability. The entire mechanism is connected by threads, allowing any component to be quickly removed for cleaning or replacement, minimizing maintenance time and costs and maximizing the efficiency of continuous operation.

[0033] The complete workflow for coating oat seeds for feed is as follows: First, oat seeds are briefly dry-mixed in a horizontal mixer 100 to ensure uniform flowability. Simultaneously, the top-mounted agitator of the agitator sprayer 200 is activated to pre-stir the coating solution, preventing the sedimentation of micronutrients and binders and ensuring uniform solution distribution. After the coating operation begins, the agitator sprayer 200 continues to agitate. The solution is drawn from the bottom of the tank by an external diaphragm pump and transported through the liquid guide pipe 300 to the detachable spraying mechanism 400. Finally, the uniform solution is atomized by the atomizing nozzle 420 and sprayed into the horizontal mixer 100. In the boiling fluidized state formed by the double-shaft staggered blades, the solution fully contacts and evenly coats the seeds. The coated seeds are then discharged from the outlet.

[0034] Working Principle: During operation, the detachable spraying mechanism 400 uses an inverted V-shaped filter 440 to intercept larger particles in the liquid, preventing clumps from entering the atomizing nozzle 420 and causing blockages, thus ensuring smooth flow. Simultaneously, the liquid is transformed into a high-speed vortex by the cross-shaped spiral guide blades 460, using centrifugal force to thoroughly disperse micro-fertilizer particles, achieving dynamic homogenization and effectively eliminating sedimentation and stratification problems, thereby ensuring uniform liquid composition and stable coating quality. Meanwhile, the annularly distributed ball bearings 470 convert equipment vibration into high-frequency micro-vibrations and transmit them to the flow channel, making it difficult for particles to adhere to the surface of key components, further preventing sedimentary blockages. The entire flow channel is reliably sealed by a fluororubber sealing ring 480, effectively eliminating the risk of leakage and drying solidification. Finally, a uniform and stable liquid smoothly passes through the atomizing nozzle 420 to form uniform droplets. Furthermore, the detachable design makes maintenance and cleaning extremely convenient, significantly reducing downtime and improving continuous operation efficiency.

[0035] It should be noted that the horizontal mixer 100, the stirring sprayer 200, and the atomizing nozzle 420 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the horizontal mixer 100 and the stirring sprayer 200 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
