Description

Technical Field

[0001] This utility model relates to the field of feed storage equipment technology, and in particular to a device for preventing feed stratification. Background Technology

[0002] During feed production and storage, stratification easily occurs due to differences in the physical properties of feed ingredients, such as particle size, density, and shape. Uneven stratification leads to uneven nutrient distribution, resulting in unbalanced nutrient intake for animals and negatively impacting growth, development, and production performance. Furthermore, feed is prone to absorbing moisture and clumping during storage due to environmental humidity, further reducing feed quality. Currently available anti-stratification devices often lack drying functions, failing to effectively address the problem of feed moisture absorption and thus failing to meet actual production needs. Utility Model Content

[0003] The purpose of this invention is to provide a feed stratification prevention device, which not only enables the feed to be fully mixed during transportation and storage, effectively preventing feed stratification, but also dries the feed, preventing it from absorbing water and clumping, and improving feed quality.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A feed anti-segregation device includes a storage tank, a stirring assembly, and a drying assembly;

[0006] Storage bin: It has a feed inlet on the top and a discharge outlet on the side;

[0007] The stirring assembly includes a rotating shaft disposed inside the storage tank, spiral stirring blades disposed outside the rotating shaft and multiple stirring shafts, and a drive motor disposed at the top of the storage tank and fixedly connected to the top of the rotating shaft; the stirring shaft has a hollow structure.

[0008] Drying assembly: includes a first drying bag in the shape of a strip disposed inside the stirring shaft, a plurality of first vent holes disposed on the stirring shaft, and a first sealing cap detachably disposed at the opening end of the stirring shaft to prevent the first drying bag from falling out of the stirring shaft.

[0009] Preferably, the surface of the spiral stirring blade is provided with a plurality of first protrusions.

[0010] Preferably, the inner wall of the storage box is provided with a plurality of second protrusions.

[0011] Preferably, both the first protrusion and the second protrusion are hemispherical, and a wear-resistant layer is provided on the surface of the first protrusion and the second protrusion.

[0012] Preferably, the first sealing cap is threadedly connected to the stirring shaft.

[0013] Preferably, the first drying bag is made of non-woven fabric and filled with absorbent material.

[0014] Preferably, the top cover of the storage box is detachable.

[0015] Preferably, the top surface of the top cover is provided with a drying chamber, the bottom wall of the drying chamber is provided with a plurality of second vent holes communicating with the interior of the storage box, a second drying bag is provided inside the drying chamber, and a second sealing cover is provided at the top of the drying chamber, with a sealing ring provided inside the second sealing cover.

[0016] Preferably, the inner bottom wall of the storage box is provided with a limiting ring for limiting the rotation shaft.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. By incorporating a mixing assembly, the drive motor propels the rotating shaft at high speed. The external spiral mixing blades generate a spiral thrust, forcing the feed to move axially and circularly within the storage bin, creating a complex motion trajectory and achieving initial mixing. Multiple hollow mixing shafts rotate synchronously, further refining the mixing process. Working in conjunction with the spiral mixing blades, they ensure thorough mixing of the feed, preventing stratification caused by differences in particle size and density.

[0019] 2. By setting a first drying bag inside the mixing shaft and a first vent on the mixing shaft, moisture in the feed can enter the first drying bag through the first vent to absorb moisture, reduce humidity inside the box, effectively prevent feed from absorbing water and clumping, and effectively ensure feed quality.

Detailed Implementation

[0024] Example 1

[0025] A device to prevent feed stratification, such as Figure 1 As shown, it includes a storage tank 1, a mixing assembly, and a drying assembly; wherein, as Figure 1-3 As shown, the storage tank 1 has a feed inlet 2 on the top and a discharge outlet 3 on the side. Both the feed inlet 2 and the discharge outlet 3 are equipped with corresponding pistons or baffles (not shown in the figure as both are existing technologies) to ensure the internal sealing of the storage tank 1. Figure 1-2 As shown, the stirring assembly includes a rotating shaft 4 disposed inside the storage tank 1, spiral stirring blades 5 disposed outside the rotating shaft 4, multiple stirring shafts 6, and a drive motor 7 disposed at the top of the storage tank 1 and fixedly connected to the top of the rotating shaft 4; the stirring shaft 6 has a hollow structure. Figure 1-2 As shown, the drying assembly includes a first drying bag 8 in the shape of a strip disposed inside the stirring shaft 6, a plurality of first vent holes 9 (the hole diameter is smaller than the diameter of the feed pellets) disposed on the stirring shaft 6, and a first sealing cap 10 detachably disposed at the opening end of the stirring shaft 6 to prevent the first drying bag 8 from falling out of the stirring shaft 6.

[0026] Furthermore, the first drying bag 8 is made of non-woven fabric and filled with absorbent material (such as silica gel desiccant or montmorillonite desiccant). The non-woven fabric has good air permeability, ensuring that moisture can pass through smoothly. Furthermore, the top cover of the storage box 1 is removable. Furthermore, as... Figure 1 As shown, the top cover of the storage bin 1 is removable. The removable top cover facilitates cleaning, inspection, installation, and replacement of the drying components inside the storage bin 1 by operators, improving the convenience and efficiency of maintenance. Furthermore, as... Figure 1-2 As shown, the inner bottom wall of the storage tank 1 is provided with a limiting ring 16 for limiting the rotation shaft 4. The limiting ring 16 can limit the radial displacement of the rotation shaft 4 during rotation, ensure the stability of the rotation shaft 4, prevent the stirring component from colliding and rubbing against the inner wall of the storage tank 1 due to shaking of the rotation shaft 4, and extend the service life of the equipment. In actual implementation, the rotation shaft 4 and the limiting ring 16 are detachably connected, and the two are not interference fits.

[0027] Working Principle: Feed enters the storage tank 1 through the feed inlet 2 at the top. When mixing is required, the drive motor 7 is started, which drives the rotating shaft 4 to rotate. The spiral mixing blades 5 on the outside of the rotating shaft 4 rotate accordingly. The rotation of the spiral mixing blades 5 generates spiral thrust, pushing the feed axially within the storage tank 1 while simultaneously performing circular motion, creating a complex motion trajectory for the feed within the storage tank 1, achieving initial mixing. Multiple mixing shafts 6 on the rotating shaft 4 also rotate synchronously with the rotating shaft 4. The mixing shafts 6 have a hollow structure, and the first drying bag 8 inside can exchange moisture with the feed through the first vent hole 9, drying the feed during the mixing process. The mixing action of the mixing shafts 6 further refines the mixing of the feed, working together with the spiral mixing blades 5 to ensure thorough mixing and prevent stratification.

[0028] When feed needs to be discharged, it can be discharged directly from the discharge port 3 on the side of the storage box 1.

[0029] Example 2

[0030] Based on Example 1, such as Figure 1-2 As shown, the surface of the spiral mixing blade 5 is provided with multiple first protrusions. The first protrusions can increase the friction between the spiral mixing blade 5 and the feed when the spiral mixing blade 5 rotates, so that the feed generates stronger disturbance during the pushing and mixing process, enhances the mixing effect, and further prevents the feed from separating.

[0031] Furthermore, such as Figure 1-2 As shown, the inner wall of the storage bin 1 is provided with a plurality of second protrusions 12. The second protrusions 12 can change the flow direction of the feed near the inner wall of the storage bin 1. When the feed hits the second protrusions 12 during the mixing process, it will produce irregular rebound and flow, which, together with the mixing action of the spiral mixing blades 5 and the mixing shaft 6, forms a more complex feed movement path, making the feed mix more uniform and improving the anti-segregation effect.

[0032] Furthermore, such as Figure 1-2 As shown, both the first and second protrusions 12 are hemispherical, and a wear-resistant layer (existing technology, not shown in the figure) is provided on the surface of the first and second protrusions 12. The hemispherical design can reduce the accumulation of feed at the protrusions, avoid feed particle damage due to sharp edges, and ensure smooth feed flow. The wear-resistant layer can reduce the decrease in mixing effect caused by wear and extend the service life of the first and second protrusions 12.

[0033] Furthermore, the first sealing cap 10 is threadedly connected to the stirring shaft 6 to improve the ease of disassembly and installation.

[0034] Example 3

[0035] Based on Example 1 or 2, such as Figure 2-3 As shown, a drying chamber 13 is provided on the top surface of the top cover. The bottom wall of the drying chamber 13 has multiple second ventilation holes 14 communicating with the interior of the storage bin 1. A second drying bag is provided inside the drying chamber 13. A second sealing cap 15 is provided at the top of the drying chamber 13, and a sealing ring (existing technology, not shown in the figure) is provided inside the second sealing cap 15. The first drying bag 8 is made of non-woven fabric and filled with absorbent material, such as silica gel desiccant or montmorillonite desiccant.

[0036] In this embodiment, the second drying bag in the drying chamber 13 can pre-dry the air inside the storage tank 1, reducing the ambient humidity inside the storage tank 1 and decreasing the possibility of feed getting damp; the second vent 14 ensures air circulation while preventing feed from entering the drying chamber 13; the sealing ring inside the second sealing cover 15 ensures the airtightness of the drying chamber 13, preventing external moisture from entering and enhancing the overall drying effect. This embodiment, in conjunction with the drying components in Embodiment 1, can effectively improve the absorption of moisture inside the storage tank 1, effectively preventing the problem of feed clumping due to moisture absorption.
