Description

Technical Field

[0001] This utility model relates to the field of feed additive screening technology, specifically a feed additive screening and filtration device. Background Technology

[0002] Feed additives refer to small or trace amounts of substances added during feed production, processing, and use to improve animal production performance, ensure animal health, save feed costs, and improve livestock product quality. To avoid impurities in feed additives, they need to be filtered through screening and filtration devices. Existing screening and filtration devices for feed additives rely on screens for sieving. However, after sieving, cleaning impurities from the screen surface requires manual access from a height to retrieve the material from the screen inside the chamber. This is physically demanding, and prolonged work at height poses significant safety risks. Therefore, a screening and filtration device that addresses these drawbacks is needed to improve efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a feed additive screening and filtration device to solve the problems mentioned in the background art. In the use of existing feed additive screening and filtration devices, screening is completed by relying on a screen. However, after screening, if impurities are cleaned from the surface of the screen, manual labor is required to retrieve the screen from the box. This results in high labor intensity and long-term high-altitude work, which poses a significant safety risk.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a feed additive screening and filtration device, comprising:

[0006] A screening and filtering structure, the screening and filtering structure including a box body, wherein a screen is slidably provided on the upper end of the inner wall of the box body;

[0007] A mechanical drive structure includes guide grooves and mounting frames. The guide grooves are equidistantly opened on the inner wall of the box, and guide blocks are slidably arranged in the guide grooves. The inner side of the guide blocks is fixed to the outer periphery of the screen. A set of mounting frames is symmetrically arranged, and a rotating motor is installed through the upper part of one side of the mounting frame. A drum is sleeved in the middle of the output end of the rotating motor, and a drag rope is wound on the outer surface of the drum. One end of the drag rope is bolted to the top of the set of guide blocks.

[0008] Furthermore, a shaft is fixed to the top of the inner wall of a set of guide grooves, and a guide wheel is movably sleeved in the middle of the shaft, with the middle of the guide wheel rolling against the outer surface of the drag rope roller.

[0009] Furthermore, a bearing seat is provided through the upper part of the other side of the mounting bracket, and one end of the rotating motor output end is sleeved and extends into the bearing seat.

[0010] Furthermore, it also includes a limiting and anti-detachment structure, which includes a limiting ring. A set of limiting rings is symmetrically sleeved on the end of the drum, and rolling grooves are equidistantly opened on the inner side of the limiting rings, in which rolling balls are rolled.

[0011] Furthermore, it also includes a support structure, which includes a support plate that is equidistantly snapped onto the lower part of the outer surface of the box, and a support column is provided through the middle of one end of the support plate, with a support leg sleeved at the lower end of the support column.

[0012] Furthermore, the upper part of the outer surface of the support has a threaded ring that extends into the upper end of the support plate.

[0013] This utility model has the following beneficial effects:

[0014] This invention uses a sliding connection to support the screen and applies force to the drum with the help of a rotating motor. The force applied by the rotating motor is transmitted to the screen using a drag rope. Under the sliding action, the screen inside the box can be mechanically moved upward without manual operation, thereby reducing the intensity of manual operation, reducing the time spent on high-altitude operations, reducing operational risks, and improving the use effect.

[0015] Based on the aforementioned beneficial effects, the use of a drum to support the drag rope allows the drag rope, which is in the process of mechanically moving and cleaning the screen, to be limited by the limiting ring during winding, thus preventing it from coming off. Furthermore, the inner wall of the limiting ring is provided with multiple balls that roll at equal intervals. Through rolling contact with the drag rope, the contact friction between the drag rope and the inner wall of the limiting ring can be reduced, which helps to reduce the degree and probability of damage, thereby reducing the cost of use.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 As shown, this utility model is a feed additive screening and filtration device, comprising:

[0026] The screening and filtering structure includes a box 11, and a screen 12 is slidably provided on the upper end of the inner wall of the box 11.

[0027] The housing 11 provides a screening and storage space, and the feed additives are screened using the screen 12.

[0028] The mechanical drive structure includes a guide groove 21 and a mounting frame 23. The guide groove 21 is equidistantly opened on the inner wall of the box 11, and a guide block 22 is slidably provided in the guide groove 21. The inner side of the guide block 22 is fixed to the outer side of the screen 12. A set of mounting frames 23 is symmetrically arranged, and a rotating motor 24 is provided through the upper part of one side of the mounting frame 23. A drum 25 is sleeved in the middle of the output end of the rotating motor 24, and a drag rope 26 is wound on the outer surface of the drum 25. One end of the drag rope 26 is bolted to the top of a set of guide blocks 22.

[0029] Mounting bracket 23 is used to mount and fix rotating motor 24. Rotating motor 24 provides power source. Drum 25 winds and rewinds drag rope 26. Drag rope 26 is used to connect to a set of guide blocks 22 and apply force to rotating motor 24 for transmission. Then, by sliding guide blocks 22 in guide groove 21, screen 12 can be mechanically and conveniently moved upward inside box 11.

[0030] A shaft 27 is fixed at the top of the inner wall of a set of guide grooves 21, and a guide wheel 28 is movably sleeved in the middle of the shaft 27. The middle of the guide wheel 28 rolls and fits against the outer surface of the drag rope 26.

[0031] The shaft 27 is mounted on the guide wheel 28. The rolling motion between the guide wheel 28 and the drag rope 26 can guide the drag rope 26 during winding and unwinding, and reduce the friction generated by dragging.

[0032] A bearing seat is provided through the upper part of the other side of the mounting bracket 23, and one end of the output end of the rotating motor 24 is sleeved and extends into the bearing seat;

[0033] The bearing seat receives the output end of the rotating motor 24 and reduces rotational friction.

[0034] It also includes a support structure, which includes a support plate 41. The support plate 41 is equidistantly snapped onto the lower part of the outer surface of the box 11, and a support column 42 is provided through the middle of one end of the support plate 41. The lower end of the support column 42 is fitted with a support leg 44.

[0035] The upper part of the outer surface of the support column 42 has a threaded ring 43, which extends into the upper end of the support plate 41.

[0036] The support plate 41 provides the installation environment, and the support column 42 is installed with the help of the threaded ring 43. The threaded connection allows for easy assembly and disassembly of the structure. The support column 42 is connected and fixed to the support leg 44. The contact between the support leg 44 and the ground provides the stability of the entire device structure.

[0037] Working principle: The contact between the support leg 44 and the ground ensures the stability of the entire device structure. At this time, the feed additive to be screened is gradually put into the box 11, and a vibration motor is installed on one side of the outer wall of the box 11 to screen the feed additive through the screen 12. After screening, the controlled rotating motor 24 applies rotational force to the drum 25. The rotating drum 25 winds up the drag rope 26, which in turn drives the guide block 22 to slide upward in the guide groove 21, causing the screen 12 in the box 11 to move upward. When half of the guide block 22 extends out of the guide groove 21, the screen 12 is above the box 11. Then, the impurities on the surface of the screen 12 can be cleaned by climbing up.

[0038] This solution can mechanically move the screen 12 inside the box 11 upwards without manual operation, thereby reducing the intensity of manual work, reducing the time spent on manual high-altitude work, reducing operational risks, and improving the effectiveness of use.

[0039] Please see Figure 1-4As shown, this embodiment is based on the above embodiment and also includes a limiting and anti-detachment structure. The limiting and anti-detachment structure includes a limiting ring 31. A set of limiting rings 31 are symmetrically sleeved on the end of the drum 25, and rolling grooves 32 are equidistantly opened on the inner side of the limiting rings 31. Rolling balls 33 are rolled in the rolling grooves 32.

[0040] The limiting ring 31 limits the end of the drag rope 26 during winding and unwinding to prevent it from detaching from the drum 25. The rolling groove 32 receives the ball 33. By utilizing the rolling contact between the ball 33 and the drag rope 26, the friction between the drag rope 26 and the inner wall of the limiting ring 31 can be reduced, thereby reducing its own damage and helping to reduce costs.

[0041] Working principle: During the winding and unwinding process of the drum 25 driven by the rotating motor 24, the limiting ring 31 at the end of the drum 25 limits the movement of the rope 26. During the limiting process, the rope 26 is prevented from directly contacting the inner wall of the limiting ring 31 by the rolling contact between multiple balls 33 and the rope 26.

[0042] This solution, while preventing the drag rope 26 from detaching from the drum 25 during winding and unwinding, can reduce the friction between the drag rope 26 and the inner wall of the limiting ring 31 by using multiple rolling balls 33 to make rolling contact with it, thereby reducing the wear of the drag rope 26 and helping to reduce costs.

[0043] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
