Technical Field

[0001] This utility model relates to the field of feed grading device technology, and in particular to a feed screening and grading device. Background Technology

[0002] During the production process, pelleted feed and powdered feed need to be separated to achieve feed grading, so that pelleted feed and powdered feed can be collected separately and processed centrally.

[0003] In practical applications, existing feed grading devices have relatively complete structures and functions, which can meet basic usage requirements, but the following problems still exist:

[0004] During use, granular feed tends to accumulate on the top of the screening disc, which affects the filtration of powder. At the same time, the screening disc is usually fixed to the inner wall of the grading tank, which makes it very inconvenient to deal with once the screening disc becomes clogged. In addition, powdered feed tends to clump together at the bottom after falling to the bottom, which affects the quality and use of the feed.

[0005] Therefore, this utility model provides a feed screening and grading device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies and provide a feed screening and grading device.

[0008] In a preferred embodiment, a drive motor is fixedly installed on the top of the cover plate, and a transmission rod is fixedly connected to the output end of the drive motor. A screening circular plate is rotatably connected to the outer surface of the transmission rod, and a connecting block is fixedly connected to the outer surface of the transmission rod. A rectangular frame is fixedly connected to one side of the connecting block, and a rectangular block is engaged with the inner wall of the rectangular frame.

A third screw hole is provided at the top of the rectangular frame, and a fourth screw hole is provided at the top of the rectangular block. Threaded locking rods are threadedly connected to the inner walls of the third and fourth screw holes.

[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the rectangular card block and the rectangular card frame, the scraper and other components can be disassembled and assembled, so that the transmission rod can drive the scraper to rotate during the rotation, thereby pushing the granular feed on the top of the screening disc to avoid affecting the filtration of powdered feed. At the same time, the cover plate can drive the screening disc and other components to be disassembled, so that the screening disc can be removed for maintenance after it becomes clogged.

[0010] In a preferred embodiment, an annular locking block is fixedly connected to the bottom of the screening disc, an annular locking frame is fixedly connected to the inner wall of the grading tank, a circular insert rod is fixedly connected to the bottom of the annular locking block, and a circular insertion hole is provided on the inner wall of the annular locking frame.

[0011] The technical effect of adopting the above-mentioned further solution is that the annular card block and the annular card frame can be engaged, so that the round insert rod can be inserted into the inner wall of the round insert hole, so that when the transmission rod rotates on the inner wall of the screening disc, it will not drive the screening disc to rotate together, thereby improving the stability of the screening disc during the screening process.

[0012] In a preferred embodiment, a rotating rod is rotatably connected to the inner wall of the auxiliary plate, and several stirring rods of unequal lengths are fixedly connected to one side of the rotating rod. A brush plate is fixedly connected to one end of the stirring rod, and the brush plate is in contact with the inner surface of the powder outlet. A rectangular positioning frame is fixedly connected to the top of the rotating rod, and a rectangular positioning block is fixedly connected to the bottom of the transmission rod.

[0013] The technical effect of adopting the above-mentioned further solution is that, under the action of the rectangular positioning frame and the rectangular positioning block, the transmission rod can drive the brush plate to rotate, thereby cleaning the inner wall of the powder discharge port and preventing powdered feed from adhering.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting up a grading and screening structure, powdered and granular feeds can be screened and graded under the action of the screening disc. At the same time, the feed on the top of the screening disc can be pushed by the scraper, which can assist in the screening and prevent granular feed from accumulating and clogging on the top of the screening disc. The screening disc can also be disassembled by the cover plate and other components, which can be used for maintenance. By setting up a stirring structure, the rectangular clamping blocks and rectangular clamping frames can drive the rotating rod to rotate, which in turn drives the stirring rod and brush plate to rotate, thereby breaking up the powdered feed and preventing it from caking. At the same time, it can clean the inner wall of the powder outlet to prevent powdered feed from adhering. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0027] like Figures 1-6 As shown, this embodiment provides a technical solution: a feed screening and grading device, including a grading tank 1, a fixing ring 2 fixedly connected to the outer surface of the grading tank 1, a support rod 3 fixedly connected to the outer surface of the fixing ring 2, a powder outlet 4 fixedly connected to the bottom of the grading tank 1, and a particle outlet 5 provided on one side of the grading tank 1; a grading and screening structure 6 is provided on the top of the grading tank 1, the grading and screening structure 6 includes a cover plate 61, a first screw hole 62 is opened on the inner wall of the cover plate 61, an annular plate 63 is fixedly connected to the top of the grading tank 1, a second screw hole 64 is opened on the inner wall of the annular plate 63, a threaded clamp 65 is threadedly connected to the inner wall of the first screw hole 62 and the second screw hole 64, and a feed inlet 66 is fixedly connected to the top of the cover plate 61; a stirring structure 7 is provided on the inner wall of the grading tank 1, the stirring structure 7 includes an auxiliary plate 71, the auxiliary plate 71 is fixed to the inner surface of the grading tank 1. The connection, through the setting of the grading and screening structure 6, under the action of the screening disc 69, can screen and grade powdered feed and granular feed. At the same time, under the action of the scraper 617, the feed on the top of the screening disc 69 can be pushed, thereby assisting in the screening of the feed and preventing granular feed from accumulating on the top of the screening disc 69 and causing blockage. At the same time, under the action of the cover plate 61 and other components, the screening disc 69 can be disassembled, thereby enabling maintenance of the screening disc 69. Through the setting of the stirring structure 7, under the action of the rectangular locking block 74 and the rectangular locking frame 73, the rotating rod 72 can be driven to rotate, thereby driving the stirring rod 75 and the brush plate 76 to rotate, thereby breaking the powdered feed and preventing the powdered feed from caking. At the same time, it can clean the inner wall of the powder outlet 4 to prevent the powdered feed from adhering.

[0028] Going further, such as Figures 3-4As shown: A drive motor 67 is fixedly installed on the top of the cover plate 61. A transmission rod 68 is fixedly connected to the output end of the drive motor 67. A screening circular plate 69 is rotatably connected to the outer surface of the transmission rod 68. A connecting block 610 is fixedly connected to the outer surface of the transmission rod 68. A rectangular frame 611 is fixedly connected to one side of the connecting block 610. A rectangular block 612 is engaged with the inner wall of the rectangular frame 611. An auxiliary through groove 616 is provided at the bottom of the rectangular frame 611. A connecting rod 622 is fixedly connected to the bottom of the rectangular block 612. A scraper 617 is fixedly connected to the bottom end of the connecting rod 622. A third screw is provided at the top of the rectangular frame 611. The top of the rectangular locking block 612 has a fourth screw hole 614. The inner walls of the third screw hole 613 and the fourth screw hole 614 are threadedly connected to a threaded locking rod 615. Under the action of the rectangular locking block 612 and the rectangular locking frame 611, the scraper 617 and other components can be disassembled and assembled. In this way, the transmission rod 68 can drive the scraper 617 to rotate during rotation, which can push the granular feed on the top of the screening disc 69 to avoid affecting the filtration of powdered feed. At the same time, the cover plate 61 can drive the screening disc 69 and other components to be disassembled, so that the screening disc 69 can be removed for maintenance after it becomes blocked.

[0029] The above solution also has the problem that the screening disc 69 tends to rotate along with the transmission rod 68 when the transmission rod 68 rotates. Figure 3 and Figure 4 As shown: In this scheme, an annular locking block 620 is fixedly connected to the bottom of the screening circular plate 69, and an annular locking frame 618 is fixedly connected to the inner wall of the grading tank 1. A circular insertion rod 621 is fixedly connected to the bottom of the annular locking block 620. A circular insertion hole 619 is opened on the inner wall of the annular locking frame 618. The annular locking block 620 and the annular locking frame 618 can be locked together, so that the circular insertion rod 621 can be inserted into the inner wall of the circular insertion hole 619. Therefore, when the transmission rod 68 rotates on the inner wall of the screening circular plate 69, it will not drive the screening circular plate 69 to rotate together, thereby improving the stability of the screening circular plate 69 during the screening process.

[0030] The above solutions also have the problem that powdered feed tends to clump together at powder outlet 4 and easily adheres to the inner wall of powder outlet 4. Figures 4-6 As shown, a rotating rod 72 is rotatably connected to the inner wall of the auxiliary plate 71. Several stirring rods 75 of unequal lengths are fixedly connected to one side of the rotating rod 72. A brush plate 76 is fixedly connected to one end of the stirring rod 75. The brush plate 76 is in contact with the inner surface of the powder outlet 4. A rectangular positioning frame 73 is fixedly connected to the top of the rotating rod 72. A rectangular positioning block 74 is fixedly connected to the bottom of the transmission rod 68. Under the action of the rectangular positioning frame 73 and the rectangular positioning block 74, the rotating rod 72 can drive the brush plate 76 to rotate, thereby cleaning the inner wall of the powder outlet 4 and preventing powdered feed from adhering.

[0031] Working principle:

[0032] like Figure 1-6 As shown:

[0033] In use: the rectangular card block 612 is engaged with the rectangular card frame 611. At this time, the threaded locking rod 615 is fixed with the third screw hole 613 and the fourth screw hole 614, which can then fix the scraper 617.

[0034] At this time, the cover plate 61 is fixed to the first screw hole 62 and the second screw hole 64 by the threaded clamp rod 65. At this time, the annular clamping block 620 on the screening circular plate 69 can be engaged with the annular clamping frame 618. At this time, the circular insertion rod 621 can be inserted into the inner wall of the circular insertion hole 619, and the rectangular clamping block 74 can be engaged with the rectangular clamping frame 73.

[0035] At this time, the drive motor 67 is started, which enables the transmission rod 68 to drive the scraper 617 to rotate, thereby cleaning the top of the screening disc 69. At the same time, the transmission rod 68 can drive the rotating rod 72 to rotate, which in turn drives the stirring rod 75 to rotate, which in turn drives the brush plate 76 to rotate, thereby stirring the powdered feed and cleaning the powdered feed adhering to the inner wall of the powder outlet 4 to prevent adhesion.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
