[0003] When mixing feed, a feed mixer is usually used. The private chat formula is poured into the feed mixer in batches according to the proportion.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-11 The present invention provides a technical solution: a conveying device with a feed mixing function, comprising a mixer body 1, a mixing blade 11 is rotatably connected inside the mixer body 1, a driving motor 12 is arranged on one side of the mixer body 1, and an output shaft of the driving motor 12 can drive the mixing blade 11 to rotate;

[0034] A cleaning mechanism 2, which is located above the mixer body 1 and can clean the feed attached to the surface of the mixing blade 11;

[0035] The scraping mechanism 3 is located inside the stirring mechanism body, and the scraping mechanism 3 can scrape the inner wall of the stirring machine body 1 after the cleaning mechanism 2 cleans the stirring blades 11;

[0036] When the present invention is in use, when the feed inside the mixer body 1 is being stirred, the feed attached to the outside of the stirring blade 11 can be cleaned by the cleaning mechanism 2, and the stirring blade 11 can be cleaned continuously and in stages by the reciprocating screw 56 to avoid the stirring blade 11 from sticking and agglomerating;

[0037] At the same time, after cleaning the mixing blades 11, the scraping mechanism 3 is used to scrape the bottom of the cleaning plate 22 and the inner wall of the mixer body 1, and the scraped feed directly enters the mixer body 1, which not only does not cause feed waste and avoids the mixing blades 11 from sticking, but also makes cleaning after use more convenient.

[0038] The cleaning mechanism 2 includes a plurality of sliding grooves 21 opened above the mixer body 1, each of which is slidably connected with a cleaning plate 22, the lower end of the cleaning plate 22 is located inside the mixer body 1, the bottom of the cleaning plate 22 is flush with the inner wall of the mixer body 1, the upper end of each cleaning plate 22 is fixedly connected, and both ends of the cleaning plate 22 are provided with a limiting member 4 for limiting the cleaning plate 22, and one side of the cleaning plate 22 is provided with a driving member 5 for driving the cleaning plate 22 to slide;

[0039] When the mixer body 1 is in use, the mixing blades 11 inside the mixer body 1 are driven by the driving motor 12 to mix the feed, and the cleaning plate 22 inside the sliding groove 21 located at the upper end of the mixer body 1 slides up and down through the driving member 5. When the cleaning plate 22 slides downward, the multiple mixing blades 11 will pass through the gaps between each cleaning plate 22 respectively, and the feed located on the outer wall of the mixing blade 11 will be scraped off by the cleaning plate 22, thereby separating from the mixing blade 11. Part of the feed will directly fall into the mixer body 1, and part of the feed will adhere to the outer wall of the cleaning plate 22. When the cleaning plate 22 slides upward, the feed located on the outer wall of the cleaning plate 22 will be scraped off by the sliding groove 21, thereby remaining in the mixer body 1, which will not only avoid feed waste, but also clean the mixing blade 11, increase mixing efficiency, and reduce feed agglomeration.

[0040] The limiting member 4 includes limiting blocks 41 fixedly connected at both ends of the cleaning plate 22, the outer wall of the mixer body 1 is fixedly connected to the limiting plate 42, and a limiting groove 43 is opened at one end of the limiting plate 42 close to the cleaning plate 22, and the limiting block 41 is located inside the limiting groove 43 and is slidably connected to the limiting groove 43; when the cleaning plate 22 slides up and down, the limiting blocks 41 located at both ends of the cleaning plate 22 are located inside the limiting groove 43 opened by the limiting plate 42 and slide, which can limit the sliding direction of the cleaning plate 22, and ensure that the feed on the outer wall of the cleaning plate 22 is scraped off the inner wall of the sliding groove 21.

[0041] The driving member 5 includes a belt 51 sleeved on the outer periphery of the output shaft of the driving motor 12, and a driving rod 52 sleeved inside the belt 51. The outer periphery of the driving rod 52 is rotatably connected to a base 53, the base 53 is located at the upper end of the mixer body 1 and is fixedly connected to the outer wall of the mixer body 1, and the end of the driving rod 52 away from the driving motor 12 is fixedly connected to a bevel gear 1 54, and the outer wall of the mixer body 1 is rotatably connected to a bevel gear 2 55, the bevel gear 1 54 is meshed with the bevel gear 2 55, and the upper end of the bevel gear 2 55 is fixedly connected to a reciprocating screw rod 56, and the outer periphery of the reciprocating screw rod 56 is threadedly connected to a sliding rod 57, and the sliding rod 57 is fixedly connected to the sliding plate;

[0042] When the mixer body 1 is in use, the output shaft of the driving motor 12 drives the driving rod 52 to rotate through the belt 51. At this time, the driving rod 52 is located inside the base 53 and rotates. The bevel gear 1 54 located at the end of the driving rod 52 is meshed with the bevel gear 2 55, and the bevel gear 2 55 is fixedly connected to the reciprocating screw rod 56. When the driving rod 52 rotates, the reciprocating screw rod 56 can be driven to rotate through the bevel gear 2 55. When the sliding rod 57 located on the outer periphery of the reciprocating screw rod 56 slides up and down, it can drive the cleaning plate 22 to slide, thereby realizing that the cleaning plate 22 intermittently extends into the interior of the mixer body 1 to scrape and clean the mixing blades 11.

[0043] The scraping mechanism 3 includes a rotating disk 31 fixedly connected to the upper end of the reciprocating screw rod 56, a rotating groove 32 is provided inside the rotating disk 31, a spring 33 is fixedly connected to the inner wall of the rotating groove 32, and a rotating block 34 is fixedly connected to the end of the spring 33 away from the inner wall of the rotating groove 32, and the rotating block 34 is located inside the rotating groove 32 and is slidably connected to the rotating groove 32. A scraping member 6 for scraping the inner wall of the mixer body 1 is provided outside the mixer body 1, and a trigger member 7 that can trigger the scraping member 6 to scrape is provided at the end of the rotating disk 31 away from the sliding rod;

[0044] The trigger member 7 comprises a trigger plate 71 fixedly connected to the outer wall of the mixer body 1, a trigger groove 72 is provided at one end of the trigger plate 71 close to the rotating disk 31, the trigger groove 72 corresponds to the position of the rotating disk 31, a second spring 73 is fixedly connected to the inner wall of the trigger groove 72, a trigger block 74 is fixedly connected to the end of the second spring 73 away from the inner wall of the trigger groove 72, a slide groove 75 is provided in the center of the trigger block 74, an electromagnet 76 is slidably connected inside the slide groove 75, a convex block 77 is fixedly connected to the inner wall of the trigger groove 72, the convex block 77 is located in the center of the second spring 73 and corresponds to the position of the electromagnet 76, and the convex block 77 is located at the end of the second spring 73 away from the trigger block 74;

[0045] When the reciprocating screw rod 56 rotates, the rotating disk 31 located at the upper end of the reciprocating screw rod 56 can be driven to rotate. When the rotating disk 31 rotates, the rotating block 34 located inside the rotating groove 32 can be thrown out by centrifugal force. At this time, the spring 1 33 is stretched. When the rotating block 34 extends out of the rotating disk 31, it can move the trigger block 74 located inside the trigger groove 72. At this time, the trigger block 74 slides inside the trigger groove 72 and squeezes the spring 2 73. The electromagnet 76 located in the center of the trigger block 74 abuts against the protrusion 77. At this time, the electromagnet 76 slides inside the slide groove 75 and moves away from the spring 2 73.

[0046] When the rotating disk 31 stops rotating, the spring 1 33 resets and pulls back the rotating block 34. At this time, the rotating block 34 no longer moves the trigger block 74. The spring 2 73 can push the trigger block 74 when it resets. Since the inner wall of the trigger groove 72 is fixedly connected with the electrode sheet 78, the electrode sheet 78 is located at the end of the trigger block 74 away from the spring 2 73, the electrode sheet 78, the electromagnet 76 and the electric telescopic rod 61 are connected in circuit. At this time, the trigger block 74 slides toward the electrode sheet 78, and the electromagnet 76 extending out of the trigger block 74 hits the electrode sheet 78. At this time, the electromagnet 76 contacts the electrode sheet 78 and sends a power-on signal to the electric telescopic rod 61. The electric telescopic rod 61 can scrape the inner wall of the mixer body 1 through the scraping member 6. After the electromagnet 76 hits the electrode sheet 78, due to inertia, the electromagnet 76 slides in the direction of the spring 2 73. At this time, the electromagnet 76 is separated from the electrode sheet 78, preparing for the next lifting of the protrusion 77.

[0047] The scraper 6 includes an electric telescopic rod 61 fixedly connected to the outer wall of the mixer body 1, a conductive ring 62 is slidably connected to the outer periphery of the electric telescopic rod 61, a scraper 63 is fixedly connected to the outer wall of the conductive ring 62, an end of the scraper 63 away from the conductive ring 62 is located inside the mixer body 1 and close to the inner wall of the mixer body 1, a conductive sheet 64 is fixedly connected to the outer periphery of the electric telescopic rod 61, and the conductive sheet 64, the conductive ring 62 and the electric telescopic rod 61 are connected in circuit;

[0048] When the electric telescopic rod 61 is energized, it means that the rotating disk 31 no longer rotates. At this time, the reciprocating screw rod 56 no longer drives the cleaning plate 22 to slide. The cleaning plate 22 slides upward to the bottom and is flush with the inner wall of the mixer body 1. When the electric telescopic rod 61 is energized, it can drive the conductive ring 62 to slide on the outer periphery of the electric telescopic rod 61. At this time, the conductive ring 62 drives the scraper 63 to scrape the inner wall of the mixer body 1. When the conductive ring 62 slides to the other end and contacts the conductive sheet 64, the electric telescopic rod 61 is powered off. There is feed on the side and bottom of the mixer body 1. Through stirring, solids and liquids are thrown on the inner wall of the mixer body 1. The feed will not dry out or agglomerate. As for the top surface, less feed, additives, etc. are thrown on the top surface. Therefore, the feed on the top surface is more likely to agglomerate. The scraper 63 scrapes the feed on the top surface, which not only avoids feed waste, but also makes it more convenient to clean the mixer body 1.
