Description

Technical Field

[0001] This utility model relates to the field of feed production technology, specifically to a multi-layer grading and screening device for feed production. Background Technology

[0002] In the feed production process, the uneven particle size of raw materials and mixed feed often directly affects the nutritional uniformity, palatability, and subsequent processing stability of the finished feed. Traditional screening equipment mostly uses a single-layer screen structure, which can only achieve a single grading of qualified and unqualified feed. Multiple screenings are required to obtain feed with different particle size specifications, which not only leads to low production efficiency and increased energy consumption, but also easily causes feed loss due to repeated screening.

[0003] Utility model patent CN216460011U discloses a grading and screening device for feed production. This utility model includes a base, with a grading and screening component connected to the base via a vibration structure. The vibration structure includes support plates symmetrically fixed to the upper surface of the base, a support member between the two support plates, and crossbars symmetrically fixed to both sides of the support member. The crossbars slide through the side walls of the support plates, and several springs A are provided between the left and right sides of the support member and the support plates. When the rotating wheel rotates, it applies a force to the lifting block, causing the lifting block to move in a circular motion under the action of the crossbars, springs A, support member, and springs B. The grading and screening component on the support platform moves in a circular motion, vibrating and screening the feed within the grading and screening component. Simultaneously, the vibration screening allows the feed within the grading and screening component to move, facilitating discharge.

[0004] Although the aforementioned utility model can grade and screen feed, its discharge port position is fixed, with all three discharge ports on the same side, making it very inconvenient to collect the screened feed. Therefore, we propose a multi-layer grading and screening device for feed production. Utility Model Content

[0005] This invention provides a multi-layer grading and screening device for feed production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-layer grading and screening device for feed production includes a support platform. Universal wheels are fixedly installed at the four corners of the lower surface of the support platform. A vibration mechanism is fixedly installed at the middle of the upper surface of the support platform. A screening mechanism is fixedly installed at the top of the vibration mechanism. Counterweights are provided on both the left and right sides of the middle of the upper surface of the support platform. A handle is installed on the left side of the support platform.

[0008] The screening mechanism includes a support base, a side enclosure rotatably connected to the upper surface of the support base, and a connecting mechanism installed on the upper surface of the side enclosure.

[0009] As a preferred technical solution, a first rotating groove is provided on the outer periphery of the upper surface of the support base, and a first connecting block is welded to the left end of the outer surface of the support base.

[0010] This feature provides the first rotating slot with matching installation space for the rotation of the side enclosure, ensuring smooth rotation of the side enclosure.

[0011] As a preferred technical solution, the side enclosure includes a side enclosure body, a rotating ring welded to the middle position of the upper and lower surfaces of the side enclosure body, and a discharge port disposed on the outer surface of the side enclosure body.

[0012] This design, with its upper and lower rotating rings, allows the side enclosure to engage with both the first rotating groove of the lower support base and the upper connecting mechanism, providing a standardized interface for multi-layer stacked structures and facilitating the flexible addition or reduction of screening layers.

[0013] As a preferred technical solution, the lower rotating ring is rotatably connected to the first rotating groove, and the contact surfaces of the two are smooth.

[0014] This feature reduces rotational friction resistance on the smooth contact surface, decreases component wear, and extends service life; it also ensures smoother vibration transmission and avoids interference with screening results due to friction.

[0015] As a preferred technical solution, the connecting mechanism includes a connecting ring and a filter screen installed on the upper surface of the connecting ring. A third connecting block is welded to the left end of the outer surface of the connecting ring, a connecting post is fixed to the lower surface of the third connecting block, and a second connecting block is welded to the outer surface of the connecting ring near the third connecting block.

[0016] In this design, the connecting ring serves as the mounting carrier for the filter screen. It is fixed to the first connecting block of the support base via the third connecting block, the connecting column, and the third connecting block, achieving a detachable connection of the multi-layer structure. This facilitates the replacement and cleaning of the filter screen and makes operation convenient.

[0017] As a preferred technical solution, a second rotating groove is provided on the outer side of the lower surface of the connecting ring, a third rotating groove is provided on the outer side of the upper surface of the connecting ring, and an installation groove is provided on the inner side of the upper surface of the connecting ring.

[0018] This configuration involves the second rotating groove cooperating with the upper rotating ring of the side enclosure, and the third rotating groove providing a connection interface for the upper side enclosure, forming a standardized stacking structure. This enables flexible combinations of multi-layer screening mechanisms to adapt to different grading requirements.

[0019] As a preferred technical solution, the filter screen is installed in the mounting groove, the upper surface of the filter screen is flush with the upper surface of the connecting ring, and the upper surface of the connecting ring is flush with the uppermost end of the lower surface inside the discharge port.

[0020] This setting, with the filter screen flush with the connecting ring, prevents surface protrusions from hindering feed flow, ensures feed evenly covers the filter screen surface, and improves screening efficiency; at the same time, it reduces feed residue and simplifies cleaning.

[0021] As a preferred technical solution, the connecting column is fixedly connected to the third connecting block and the first connecting block by bolts. The screening mechanism is formed by alternating stacking of one layer of the supporting base, multiple layers of the side enclosures and multiple layers of the connecting mechanism. The filter mesh aperture in the multiple layers of the connecting mechanism increases sequentially from bottom to top.

[0022] This setup, with its bolted connections, allows for the detachable fixing of each component, ensuring the stability of the multi-layer structure while also facilitating adjustments to the number of screening layers according to production needs.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. By setting a rotatable side enclosure, the discharge position of this utility model can be adjusted as needed according to actual usage requirements, making it convenient for users.

[0025] 2. The screening mechanism is round, which avoids the problem that if a square screening mechanism is used, the feed may be shaken to the four corners and become difficult to remove. Attached Figure Description

[0036] A multi-layer grading and screening device for feed production includes a support platform 100, with casters 200 fixedly installed at the four corners of the lower surface of the support platform 100, a vibration mechanism 500 fixedly installed at the middle of the upper surface of the support platform 100, a screening mechanism 600 fixedly installed at the top of the vibration mechanism 500, counterweights 400 on both the left and right sides of the middle of the upper surface of the support platform 100, and a handle 300 installed on the left side of the support platform 100.

[0037] The screening mechanism 600 includes a support base 610, a side enclosure 620 rotatably connected to the upper surface of the support base 610, and a connecting mechanism 630 installed on the upper surface of the side enclosure 620. Through the above mechanism, multi-level grading screening can be achieved, and the discharge port 623 of each layer can be adjusted as needed to facilitate the removal of the feed after vibration filtration.

[0038] Furthermore, such as Figure 3 As shown, a first rotating groove 611 is provided on the outer periphery of the upper surface of the support base 610, and a first connecting block 612 is welded to the left end of the outer surface of the support base 610. The upper surface of the support base 610 is smooth, which reduces the friction generated by the contact between the feed and the upper surface of the support base 610, and facilitates the discharge of feed by vibration.

[0039] Furthermore, such as Figure 4As shown, the side enclosure 620 includes a side enclosure body 621, a rotating ring 622 welded to the middle of the upper and lower surfaces of the side enclosure body 621, and a discharge port 623 disposed on the outer surface of the side enclosure body 621. The rotating ring 622 on the lower side is rotatably connected to the first rotating groove 611. The contact surfaces of the two are smooth, which reduces the friction generated by the rotation of the contact surfaces and ensures that the side enclosure 620 can rotate smoothly.

[0040] In this embodiment, as Figure 5 As shown, the connecting mechanism 630 includes a connecting ring 631 and a filter screen 635 installed on the upper surface of the connecting ring 631. A third connecting block 634 is welded to the left end of the outer surface of the connecting ring 631. A connecting post 633 is fixed to the lower surface of the third connecting block 634. A second connecting block 632 is welded to the outer surface of the connecting ring 631 near the third connecting block 634. The support base 610, the side enclosure 620 and the connecting mechanism 630 are installed together by bolts between the connecting blocks and the connecting post 633.

[0041] In this embodiment, as Figure 6 As shown, a second rotating groove 6311 is provided on the outer side of the lower surface of the connecting ring 631, a third rotating groove 6312 is provided on the outer side of the upper surface of the connecting ring 631, and an installation groove 6313 is provided on the inner side of the upper surface of the connecting ring 631. The filter screen 635 is installed in the installation groove 6313, and the upper surface of the filter screen 635 is flush with the upper surface of the connecting ring 631. The upper surface of the connecting ring 631 is flush with the uppermost end of the lower inner surface of the discharge port 623, so that the filtered feed can flow out smoothly from the discharge port 623.

[0042] In this embodiment, as Figure 1 As shown, the connecting column 633 is fixedly connected to the third connecting block 634 and the first connecting block 612 by bolts. The screening mechanism 600 is formed by alternating stacking of a support base 610, multiple side enclosures 620 and multiple connecting mechanisms 630. The pore size of the filter screen 635 in the multiple connecting mechanism 630 increases from bottom to top to ensure that multiple-level screening can be achieved.

[0043] It is worth noting that the structure and working principle of the vibration mechanism 500 involved in this embodiment are all technologies that have been disclosed in the prior art, and will not be described in detail here.

[0044] In the specific use of the multi-layer grading and screening equipment for feed production in this embodiment, firstly, install a screening mechanism 600 with an appropriate number of layers according to the screening requirements. First, rotatably connect a rotating ring 622 of a side enclosure 620 in the first rotating groove 611 on the support base 610, and rotate the discharge port 623 to a suitable position as needed. Then, install a connecting ring 631 on the upper side of the side enclosure 620, and rotatably connect the second rotating groove 6311 of the connecting ring 631 to the upper rotating ring 622, ensuring that the connecting post 633, which is fixed to the lower side of a connecting block on the connecting ring 631 by bolts, can be aligned with the position of the first connecting block 612. Then, fix the lower end of the connecting post 633 to the first connecting block 612 by bolts. Then, install a filter screen 635 in the installation groove 6313. Several more layers of side enclosures 620 and connecting mechanisms 630 can be installed as needed. After installation, adjust the discharge port 623 of each layer to a suitable position and connect the receiving bag. Then, start the vibration mechanism 500 and wait for the filtration to complete.
