[0001] This utility model relates to the field of feed mixing technology, and in particular to a premixing device for feed conveying. Background Technology

[0002] With societal progress, the artificial breeding industry has developed significantly, leading to a growing demand for artificial feed. This places higher demands on the feed production industry, requiring continuous improvement of feed production equipment to meet these new needs. Premixing devices used in feed production are used to premix various feed ingredients and can also be used for small-batch production of finished feed products.

[0003] The chicken feed production and batching device described in announcement number CN220091213U includes a batching tank and a secondary crushing structure for secondary crushing of raw materials. The secondary crushing structure includes a first motor, a first rotating shaft, crushing blades, a spiral conveyor, and stirring rods. The output end of the first motor is fixedly connected to the first rotating shaft, and the outer surface of the first rotating shaft is fixedly connected to the crushing blades, the spiral conveyor, and several stirring rods. The outer surface of the batching tank is provided with a conveying and crushing structure for primary crushing of the raw materials. The conveying and crushing structure includes a conveying cylinder, a second motor, a second rotating shaft, and spiral crushing blades. The outer surface of the batching tank is fixedly connected to the conveying cylinder, and a second motor is fixedly installed at one end of the conveying cylinder.

A premixing structure for premixing raw materials is provided on the outer surface of the conveying cylinder. The premixing structure includes a feeding pipe, a premixing cylinder, a feed pipe, a solenoid valve, a feeding cylinder, and scale markings. A feeding pipe is fixedly connected to the outer surface of the conveying cylinder. A premixing cylinder is fixedly connected to the top of the feeding pipe. Several feed pipes are fixedly connected to the outer surface of the premixing cylinder. A solenoid valve is provided on each of the feed pipes. A feeding cylinder is fixedly connected to the top of each of the feed pipes. Scale markings are provided on the outer surface of each of the feeding cylinders. A feeding ring is fixedly installed inside the mixing tank. A frustum-shaped feeding shell is fixedly connected to the bottom of the feeding ring. A feeding hole corresponding to the size and position of the conveying cylinder is opened on the outer surface of the feeding ring.

[0004] Based on the above technical features, the problem is that in the prior art, since the stirring rod is arranged radially along the first rotating shaft, the stirring rod easily causes the feed to form a fixed layer when stirring the feed. That is, the feed between the two stirring rods is far away from the stirring rods, so the fluidity is poor, resulting in the feed being fixed in position and the mixing effect being greatly reduced.

[0005] Therefore, it is necessary to solve the above problems by using a premixing device for feed delivery. Utility Model Content

A support rod 20 is horizontally arranged inside the mixing tank 1 and fixedly connected to the mixing tank 1. The lower end of the stirring shaft 10 is rotatably connected to the support rod 20.

[0026] A discharge pipe 8 is connected to and fixedly installed at the funnel outlet at the bottom of the mixing tank 1. The discharge pipe 8 is used to discharge the mixed feed. A control valve 9 is fixedly installed inside the discharge pipe 8. In this embodiment, the control valve 9 is a solenoid valve.

[0027] A funnel-shaped baffle 12 is coaxially arranged inside the mixing tank 1, dividing the interior of the mixing tank 1 into an upper crushing chamber and a lower mixing chamber. The crushing chamber is used to crush feed, and the mixing chamber is used to mix the crushed feed. A stirring shaft 10 coaxially passes through the baffle 12.

[0028] The crushing chamber is equipped with crushing blades 11 and a second spiral conveying blade 13. The crushing blades 11 are arranged radially along the stirring shaft 10 and are fixedly connected to the stirring shaft 10. In this embodiment, there are multiple crushing blades 11, which are evenly distributed on the shaft of the stirring shaft 10 located in the crushing chamber. The crushing blades 11 are used to crush the feed.

[0029] The second spiral conveying blade 13 is fixed to the stirring shaft 10 circumferentially, and is located below the crushing blade 11. The bottom end of the second spiral conveying blade 13 extends into the funnel outlet at the bottom of the partition 12. The second spiral conveying blade 13 is used to convey the crushed feed.

[0030] Several mixing components are set up inside the mixing chamber, and the mixing components are evenly distributed along the circumference of the mixing shaft 10.

[0031] Specifically, each stirring assembly includes multiple stirring rods 14, which are evenly spaced along the axial direction of the stirring shaft 10. Each stirring rod 14 is arranged radially along the stirring shaft 10 and is fixedly connected to the stirring shaft 10. A push plate 21 that reciprocates radially along the stirring shaft 10 is provided between each two adjacent stirring rods 14. All push plates 21 are driven by all stirring rods 14 through a transmission assembly.

[0032] Specifically, the transmission assembly includes a scraper 18 and multiple protrusions 19. A connecting rod is fixedly provided between each pusher plate 21 and the scraper 18. The connecting rod is arranged radially along the stirring shaft 10 and forms a T-shaped structure together with the pusher plate 21.

[0033] The scraper 18 is parallel to the stirring shaft 10 and is connected to the stirring rod 14 via a telescopic component. The scraper 18 slides against the curved side wall of the mixing tank 1.

[0034] Specifically, the telescopic component includes a slide rod 17. A slot 15 is formed in the radial direction of the stirring shaft 10 at the end of the stirring rod 14 away from the stirring shaft 10. The slide rod 17 is inserted into the slot 15 and slides within it. The end of the slide rod 17 away from the stirring shaft 10 is fixedly connected to a scraper rod 18. A spring 16 is fixedly disposed between the end of the slide rod 17 near the stirring shaft 10 and the stirring rod 14. The spring 16 is positioned along the sliding direction of the slide rod 17.

[0035] Each protrusion 19 is fixed to the inner wall of the mixing tank 1 and is parallel to the stirring shaft 10. Multiple protrusions 19 are evenly distributed at equal intervals along the circumference of the mixing tank 1. The scraper 18 is in contact with all the protrusions 19 for transmission.

[0036] Each protrusion 19 has a transmission arc surface at its end near the stirring shaft 10, and the scraper 18 slides in contact with the transmission arc surface.

[0037] A feed pipe 2 for conveying feed is fixedly installed on the top of the outer side wall of the mixing tank 1, and the feed pipe 2 is inclined downward. The lower end of the feed pipe 2 is connected to the crushing chamber inside the mixing tank 1, and the upper end of the feed pipe 2 is closed and fixedly installed with a power motor 3. A rotating shaft is coaxially installed inside the feed pipe 2, and the output shaft of the power motor 3 is coaxially and fixedly connected to the rotating shaft.

[0038] A first spiral conveying blade 6 is fixedly installed circumferentially on the rotating shaft. A feeding bucket 4 is fixedly installed on the top of the outer curved surface of the feeding pipe 2, and the feeding bucket 4 is connected to the feeding pipe 2. The top of the feeding bucket 4 is closed and several feed pipes 5 are fixedly installed, and each feed pipe 5 is connected to the feeding bucket 4.

[0039] Working Principle: When using this premixing device to convey feed, firstly, the power motor 3 and drive motor 7 are started. Next, the feed to be mixed is added to the feeding tank 4 through different feed pipes 5, and the feed in the feeding tank 4 flows into the feeding pipe 2. At this time, because the output shaft of the power motor 3 drives the rotating shaft to rotate, the rotating shaft drives the first spiral conveying blade 6 to rotate, so the first spiral conveying blade 6 pushes the feed in the feeding pipe 2 into the crushing chamber. Then, because the output shaft of the drive motor 7 drives the stirring shaft 10 to rotate, the stirring shaft 10 drives the crushing blade 11 to revolve around the central axis of the stirring shaft 10, so the crushing blade 11 crushes the feed in the crushing chamber.

[0040] Next, the crushed feed is pushed into the mixing chamber by the second spiral conveyor blades 13, which in turn drive the stirring shaft 10 to rotate due to the output shaft of the drive motor 7. At this time, the stirring shaft 10 drives the stirring rod 14 to revolve around the central axis of the stirring shaft 10, thus mixing the feed in the mixing chamber.

[0041] When the mixing rod 14 mixes the feed, it drives the slide rod 17 to revolve around the central axis of the mixing shaft 10. The slide rod 17 drives the scraper 18 to revolve around the central axis of the mixing shaft 10, and the scraper 18 drives the connecting rod to revolve around the central axis of the mixing shaft 10. The connecting rod drives the push plate 21 to revolve around the central axis of the mixing shaft 10.

[0042] When the scraper 18 revolves around the stirring shaft 10, it will come into contact with the protrusion 19. At this time, the protrusion 19 pushes the scraper 18 to move radially along the stirring shaft 10 and closer to the stirring shaft 10. The scraper 18 pushes the push plate 21 to move radially along the stirring shaft 10 and closer to the stirring shaft 10 through the connecting rod. At the same time, the scraper 18 pushes the slide rod 17 to compress the spring 16.

[0043] After the scraper 18 rotates and disengages from the convex strip 19, under the elastic force of the spring 16, the slide rod 17 pushes the scraper 18 to move radially away from the stirring shaft 10. The scraper 18 pulls the push plate 21 radially away from the stirring shaft 10 through the connecting rod.

[0044] When the pusher plate 21 moves radially along the mixing shaft 10, it pushes the feed to flow radially along the mixing shaft 10, thereby increasing the fluidity of the feed.

[0045] Once the feed mixing is complete, open the discharge pipe 8 via the solenoid valve to discharge the mixed feed.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
