Description

Technical Field

[0001] The utility model relates to the technical field of feed production, in particular to a livestock feed screening device for livestock breeding. Background Art

[0002] Animal husbandry refers to an agricultural production activity that involves artificially raising and breeding livestock, utilizing their physiological functions to convert plant-based feed into animal products. In the animal husbandry production process, screening equipment is often required to ensure feed quality and remove impurities and unsuitable ingredients.

[0003] After extensive searching, the publication number is CN221335223U, which discloses a livestock feed screening device for animal husbandry. The conveying mechanism is used to convey the feed to the inside of the screening drum for screening. When the feed enters the inside of the screening drum, the first motor is started at the same time, and the first motor drives the second gear to rotate, and the first gear engaged with the second gear rotates, causing the screening drum to rotate on the fixed plate. The leakage ports of different sizes opened on the screening drum are used to screen and grade feed of different sizes. The collecting hopper is used to collect the screened and graded feed, thereby achieving the purpose of screening and grading the feed, and effectively improving the palatability of the feed when eaten by livestock.

[0004] However, when a large amount of feed is put into the screening drum at once, the existing device will cause the feed to slide down rapidly in the drum due to the influence of gravity. During this rapid sliding process, smaller feed particles may be dragged along by larger feed particles and leak out of the larger sieve holes together. This phenomenon will lead to incomplete screening, that is, small particles of feed are not properly separated. The root cause of this problem is that the angle of the screening drum is fixed and cannot be adjusted according to the physical properties of the feed and the screening requirements, making it impossible to effectively control the natural falling speed of the feed. Therefore, a livestock feed screening device for animal husbandry is proposed to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide a livestock feed screening device for animal husbandry, which has the advantage of controlling the feed falling speed, thereby improving the screening accuracy, and solves the problem in the prior art that the feed falling speed is uncontrollable, thereby reducing the screening accuracy.

The fixed connection of the inner frame provides the required stability, while the parallel design with the top frame helps maintain balance during the screening process. This combination ensures consistent and accurate screening results.

[0012] Preferably, a vibration motor is fixedly mounted on the rear end of the screen bucket, a material guide plate is fixedly mounted on the bottom front end of the screen bucket, a top cover is fixedly mounted on the top of the screen bucket, a feed chute is provided at the rear end of the top cover, and a screen is fixedly mounted on the bottom inside the screen bucket.

This design ensures that the feed chute is located directly below the rear end of the feed hopper, ensuring smooth flow of feed from the feed hopper into the sieve. The bottoms of the second adjustment racks are fixedly mounted on the top of the top covers on either side of the feed chute, providing additional support and adjustment capabilities.

[0014] Advantages: This design ensures the continuity and uniformity of feed flow, reducing feed accumulation and blockage during screening. The second adjustment frame provides more adjustment options to suit different feed types and screening requirements.

[0015] Preferably, the bottom of the screen contacts the upper end face of the buffer block but is not fixedly connected, and the buffer block is designed with a soft rubber material. In the design, the bottom of the screen contacts the upper end face of the buffer block but is not fixedly connected. This design allows the screen to have a certain degree of elasticity during the screening process, reducing the wear of the screen. The buffer block is designed with a soft rubber material, which further improves the protective effect of the screen. The non-fixed connection between the screen and the buffer block provides the elasticity of the screen, which helps to extend the service life of the screen.

[0040] Advantages: This design ensures the continuity and uniformity of feed flow and reduces feed accumulation and blockage during the screening process. The second adjustment frame 202 provides more adjustment options to accommodate different feed types and screening requirements.

[0041] Furthermore, the bottom of the screen 33 contacts the upper end surface of the buffer block 103 but is not fixedly connected, and the buffer block 103 is designed with a soft rubber material. In the design, the bottom of the screen 33 contacts the upper end surface of the buffer block 103 but is not fixedly connected. This design allows the screen 33 to have a certain degree of elasticity during the screening process, reducing the wear of the screen 33. The buffer block 103 is designed with a soft rubber material, which further improves the protective effect of the screen 33.

At this time, the opening size of the reserved slot 201 can be adjusted by the movable frame 21, so as to adjust the material discharge speed when the feed enters the screening bucket 3, and the vibration motor 31 at the rear end of the screening bucket 3 is started synchronously to make the screening bucket 3 vibrate, which helps the feed to be screened. The feed is evenly distributed in the screening bucket 3 and the screening process is accelerated. The feed is screened on the screen 33 in the screening bucket 3. Smaller feed particles that do not meet the requirements are separated through the screen 33. Larger particles of feed that do not pass through the screen 33 continue to vibrate in the screening bucket 3. Affected by the angle adjusted by the first adjustment frame 102, the residence time of the feed above the screen 33 is controllable. According to the screening effect, it may be necessary to adjust the positions of the first adjustment frame 102 and the second adjustment frame 202 again to improve the screening accuracy. After the screening is completed, the vibration motor 31 is turned off, the vibration of the screening bucket 3 is stopped, and the screened feed is stored or transported for use in animal husbandry.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
