Description

Technical Field

[0001] The present invention belongs to the technical field of feed additive processing, and particularly relates to a feed additive processing device. Background Art

[0002] With the booming development of animal husbandry and agriculture, the demand for feed additives has been continuously climbing. Among them, plant feed additives have increasingly won wide recognition in the market with their significant advantages of being natural, safe, and environmentally friendly. Such additives not only optimize the growth performance of animals, improve product quality, but also promote animal health and reduce the incidence of diseases. In order to ensure that the production of feed additives meets the specifications, it is particularly important to screen them to filter out impurities and ensure the quality of the finished products.

[0003] A prior patent document (CN117884353B) describes a feed additive screening device. After the feed additive is added to the material hopper, the driving motor is started. The driving motor drives the driving gear to rotate, and then transmits the power to the transmission shaft through the gear transmission system. The transmission shaft drives components such as the shaft sleeve and the undulating wheel to rotate. The convex part and the concave part on the undulating wheel alternately contact the rotating shaft at the lower end of the contact block. Since the lifting seat is fixedly connected to the movable end of the telescopic rod and the guide rail is inclined, the outer box will slide in the left - right direction while moving up and down. Fine particles fall into the slag storage hopper through the holes of the screening net, while larger particles remain above the screening net. When it is necessary to change the screening frequency, the lifting seat is lifted by the jacking device to separate the contact block from the current undulating wheel. The forward - reverse motor is started, and the bidirectional lead screw is driven to rotate through the gear transmission system, thereby adjusting the position of the undulating wheel, moving the undulating wheel two or the undulating wheel three to directly below the contact block, and making the contact block contact the undulating wheel again, so as to change the number of reciprocating motions of the lifting seat up and down, and further change the screening frequency.

[0004] However, after the additive is added to the material hopper, it is easy to accumulate together, and the above - mentioned screening net has a straight - plate structure, which limits the contact area with the additive particles, thereby affecting the filtering efficiency.

[0005] Based on this, a feed additive processing device is now provided to eliminate the drawbacks of the existing device. Summary of the Invention

DETAILED DESCRIPTION

[0018] The present invention will now be further described in detail by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the embodiments.

[0019] like Figures 1-7 As shown, a feed additive processing equipment includes a filter barrel 11, a feed barrel 12, a feed pipe 14, and a discharge pipe 15. The feed barrel 12 is connected to the inside of the feed pipe 14, and the feed pipe 14 is connected to the inside of the filter barrel 11 through the discharge pipe 15. The filter barrel 11 is hingedly provided with a barrel door at the front end, and the middle position of the bottom end of the filter barrel 11 is fixedly connected to the discharge pipe 44 through a conical bucket 43. An inclined block 13 is installed at the bottom of the feed barrel 12 to facilitate the material loaded into the feed barrel 12 to slide along its inclined surface to the lower end of the feed pipe 14.

[0020] The inner wall of the filter barrel 11 is fixedly connected to a fixed ring plate 33, and a plurality of reset springs 34 and a movable telescopic rod 35 are fixedly installed on the upper end of the fixed ring plate 33. The movable telescopic rod 35 is arranged inside the reset spring 34, and the upper end of the reset spring 34 and the movable end of the movable telescopic rod 35 are fixedly connected to a movable ring plate 31. A plurality of first balls 45 are rotatably installed on the upper end of the movable ring plate 31, and an arc-shaped screening net 32 ​​is fixedly installed on the inner wall of the movable ring plate 31. The bottom end of the movable ring plate 31 is fixedly connected to a baffle plate 36, and the baffle plate 36 is located inside the fixed ring plate 33.

[0021] It also includes a material transport structure, which is arranged inside the feed pipe 14 and is used to transport additives into the filter barrel 11.

[0022] The screening structure is arranged inside the filter barrel 11 and is used to evenly distribute the additives on the surface of the arc-shaped screening net 32 ​​to improve the filtering efficiency.

[0023] The driving structure is arranged at the upper end of the filter barrel 11 and is used to drive the material transporting structure and the screening structure to operate.

[0024] The stabilizing structure is arranged at the bottom of the filter barrel 11 to ensure the stable operation of the equipment.

[0025] In this embodiment, the additive is first put into the feed barrel 12. Since the bottom of the feed barrel 12 is provided with an inclined block 13, this helps the additive to flow smoothly to the feed pipe 14 under the action of gravity, and avoids accumulation in the feed barrel 12.

[0026] The driving structure drives the material transporting structure to operate, and the material transporting structure transports the additives from the feed barrel 12 to the inside of the filter barrel 11 continuously and evenly.

[0027] When the additive enters the filter barrel 11, the driving structure drives the screening structure to evenly distribute the additive on the surface of the arc-shaped screening net 32, which helps to improve the filtering efficiency and prevent the screening net from being blocked.

[0028] The additives after screening are discharged through the discharge pipe 44 .

[0029] The user can clean the impurities on the upper surface of the arc-shaped screening net 32 ​​by opening the barrel door.

[0030] The stabilizing structure is arranged at the bottom of the filter barrel 11 to ensure the stability of the equipment during operation. The stabilizing structure can reduce the impact of equipment vibration on the surrounding environment and prevent the equipment from being damaged due to excessive vibration.

[0031] In one embodiment, Figures 3-4 As shown, the material transport structure includes a transport rod 17, which is rotatably installed in the inner cavity of the feed pipe 14, and a transport blade 16 is fixedly installed on the outer wall of the transport rod 17. The upper end of the transport rod 17 extends to the outside of the feed pipe 14 and is fixedly connected to a driven wheel 18. The driven wheel 18 is connected to the driving wheel 20 through a belt 19. The upper end of the driving wheel 20 is fixedly connected to a driven gear 21, and the driven gear 21 is meshed with the driving structure.

[0032] The driving structure drives the driven gear 21 to rotate, thereby driving the driving wheel 20 to rotate. The driving wheel 20 drives the driven wheel 18 to rotate through the belt 19, and the transport rod 17 rotates synchronously. The transport blade 16 moves with the rotation of the transport rod 17. Through the rotation of the blade, the additive is continuously and evenly transported from the feed barrel 12 to the filter barrel 11, avoiding the accumulation of a large amount of additives and improving the subsequent filtration efficiency.

[0033] In one embodiment, Figures 5-6 As shown, the screening structure includes a rotating rod 24, which is rotatably installed inside the filter barrel 11, the upper end of the rotating rod 24 extends to the outside of the filter barrel 11 and the upper end is coaxially fixedly connected to the driving wheel 20, the lower end of the rotating rod 24 is fixedly connected to the rotating column 25, the bottom of the outer wall of the rotating column 25 is fixedly connected to the second arc rotating block 27 and a plurality of first arc rotating blocks 26, the rotating column 25 is fixedly connected to the second arc rotating block 27 and the upper ends of the plurality of first arc rotating blocks 26 through a reinforcing rod 29, the second arc rotating block 27 and the plurality of first arc rotating blocks 26 are located above the arc screening net 32 ​​and close to the arc screening net 32, the second arc rotating block 27 and the plurality of first arc rotating blocks 26 are fixedly connected to the fixed plate 30 at one end away from the rotating column 25, and the lower end of the fixed plate 30 is rotatably installed with a second ball 46 corresponding to the first ball 45.

[0034] The driving structure drives the driven gear 21 to rotate, thereby driving the rotating rod 24 to rotate, and the rotating column 25 rotates accordingly. The rotating column 25 is connected to the first arc rotating block 26 and the second arc rotating block 27 through the reinforcing rod 29 to enhance its structural stability. The first arc rotating block 26 and the second arc rotating block 27 rotate with the rotation of the rotating column 25. Through the design of their arc surfaces, the additives are evenly thrown onto the arc screening net 32 ​​to improve the screening efficiency. The second ball 46 can reduce the friction between the fixed plate 30 and the movable ring plate 31, making the screening process smoother. When the second ball 46 contacts the first ball 45, the movable ring plate 31 moves downward and the reset spring 34 is compressed; when the two are separated, the movable ring plate 31 moves upward under the elastic force of the reset spring 34, thereby realizing the up and down shaking of the arc screening net 32 ​​and accelerating the screening and filtering rate of the additives.

[0035] In one embodiment, Figures 1-3 As shown, the driving structure includes a motor 23 , which is mounted on the upper end of the filter barrel 11 , and the output end of the motor 23 is fixedly connected to a driving gear 22 , and the driving gear 22 is meshedly connected to the driven gear 21 .

[0036] The motor 23 drives the driving gear 22, and the driving gear 22 is meshed with the driven gear 21, and the driven gear 21 rotates accordingly, thereby driving other components in the screening structure and the material transporting structure to work.

[0037] In one embodiment, Figure 3 , Figure 7As shown, the stabilizing structure includes a bottom ring plate 37, which is arranged below the filter barrel 11. The bottom ring plate 37 is arranged around the outside of the conical bucket 43. An outer ring guard plate 40 is fixedly installed on the outer wall of the bottom ring plate 37. A plurality of legs 41 are fixedly installed on the bottom end of the bottom ring plate 37. A fixed foot 42 is fixedly installed on the bottom end of the legs 41. A shock absorbing assembly is arranged between the filter barrel 11 and the bottom ring plate 37.

[0038] The stable structure provides stable support and protection for the filter barrel 11 and its internal components through the coordinated action of the bottom ring plate 37, the outer ring guard plate 40, the support legs 41 and the fixing feet 42.

[0039] In one embodiment, Figure 7 As shown, the shock absorbing assembly includes a plurality of damping springs 38 and dampers 39 , the lower ends of the damping springs 38 and dampers 39 are fixedly connected to the upper end of the bottom ring plate 37 , and the upper ends of the damping springs 38 and dampers 39 are fixedly connected to the lower end of the filter barrel 11 .

[0040] The damping spring 38 can absorb and store the vibration energy generated by the filter barrel 11 during operation, and convert it into the potential energy of the spring. When the vibration weakens or stops, the damping spring 38 will release the stored potential energy to help the filter barrel return to a stable state. The damper 39 plays a role in limiting the vibration amplitude of the damping spring 38 and dissipating the vibration energy in the shock absorbing assembly. When the filter barrel 11 vibrates, the damper 39 will provide a certain resistance, so that the vibration of the damping spring 38 gradually decays, thereby avoiding the filter barrel 11 from generating excessive amplitude or resonance.

[0041] In one embodiment, Figure 4 As shown, the transport blade 16 is in an overall spiral shape, and an anti-slip layer (not shown) is provided on the outer surface.

[0042] By providing an anti-skid layer on the outer surface of the transport leaf 16 , the friction coefficient of the outer surface is increased, which is beneficial for the transport leaf 16 to transport the additives to the inside of the filter barrel 11 .

[0043] In one embodiment, Figure 6 As shown, a cleaning brush 28 is installed on the lower end surface of the second arc-shaped rotating block 27, and the lower end of the cleaning brush 28 is in contact with the upper end surface of the arc-shaped screening net 32. The cleaning brush 28 is located at one end of the rotating column 25 close to the center of the arc-shaped screening net 32, and the other end close to the edge of the arc-shaped screening net 32.

[0044] As the screening process proceeds, some material residues or blockages will gradually accumulate on the curved screening net 32, which will affect the screening efficiency. The cleaning brush 28 is designed to be close to the upper surface of the screening net, so that these residues can be effectively removed during the rotation process to keep the screening net 32 ​​clean and unobstructed.

[0045] The above embodiment discloses a feed additive processing device, wherein the additive is put into a feed barrel 12 and flows to a feed pipe 14 by the gravity of an inclined block 13 .

[0046] The motor 23 drives the driving gear 22 to rotate, and drives the transport rod 17 to rotate through the belt 19 , and the transport blades 16 transport the additives to the inside of the filter barrel 11 continuously and evenly.

[0047] The rotating rod 24 is connected to the driving gear 22 through the driving wheel 20. When the additive enters the filter barrel 11, the rotating rod 24 drives the first arc rotating block 26 and the second arc rotating block 27 to rotate, and the additive is evenly thrown onto the arc screening net 32 ​​by the first arc rotating block 26 and the second arc rotating block 27. At the same time, the movable ring plate 31 shakes up and down under the action of the reset spring 34 and the first ball 45 and the second ball 46 to improve the screening efficiency. The cleaning brush 28 removes the residue on the screening net.

[0048] The screened additives are discharged through the conical bucket 43 and the discharge pipe 44 .

[0049] The user can clean the impurities on the upper surface of the arc-shaped screening net 32 ​​by opening the barrel door.

[0050] The bottom ring plate 37, the outer ring guard plate 40, the legs 41 and the fixed feet 42 provide a stable support for the whole device, and the shock absorbing assembly reduces the vibration of the device during operation.

[0051] The above-mentioned technologies not specifically mentioned are all referred to the prior art.

[0052] Based on the above-mentioned ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above-mentioned description. The technical scope of the present invention is not limited to the contents of the specification.
