[0024] As a preferred embodiment: To facilitate cleaning of the feeding route, a feeding and cleaning mechanism 7 is provided on the front side of the evenly spreading mechanism 6. The feeding and cleaning mechanism 7 includes mounting blocks 701. There are two mounting blocks 701, and the two mounting blocks 701 are respectively fixedly set on both sides of the front side of the enclosure frame 601.

A second belt 705 is drivingly connected between the two second pulleys 704.

[0025] This invention also discloses a feeding method using a spray feeder for large-scale livestock farming, specifically including the following steps: S1. Feed filling: Grain feed and chopped straw are fed into the storage tank 3 in proportion through the feeding hopper 11; S2, Feeding: Use a tractor to drag the storage tank 3 to the feeding area, then start the hydraulic telescopic cylinder 2 to cause the extension end of the hydraulic telescopic cylinder 2 to retract. The hydraulic telescopic cylinder 2 retracts the storage tank 3 and causes the auxiliary wheel of the enclosure frame 601 and the brush layer 703 to touch the ground. Then the servo motor 503 is started, which causes the first auger shaft 504 and the swivel drum 501 to mix and turn the feed, while the second auger shaft 511 and the paddle 512 are linked to lower the mixed feed to the ground of the feeding area. As the tractor moves in a straight line, the feed is fed in a straight line accordingly. The specific steps are as follows: Start the servo motor 503, which drives the first auger shaft 504 and the second gear 507 to rotate. The second gear 507 rotates and meshes with the first gear 506. The first gear 506 meshes with the internal gear ring 522, causing the swirling drum 501 to rotate in the opposite direction to the first auger shaft 504. This causes the first auger shaft 504 to continuously rotate and turn the mixed material in the inner cavity of the storage tank 3. The rotation of the swirling drum 501 synchronously stirs the feed through the stirring rod 508 and the inclined rod 509. During the rotation of the swirl cylinder 501, the swirl cylinder 501 synchronously drives the fourth gear 521 to rotate. The rotation of the fourth gear 521 meshes with the third gear 520, causing the rotating rod 518 to drive the cutting blade 519 to rotate and cut, so that the forage can be crushed more thoroughly and mixed more fully with the grain feed. During the rotation of the first auger shaft 504 driven by the servo motor 503, the first auger shaft 504 synchronously drives the first pulley 515 and the first belt 516 to perform transmission cooperation, thereby causing the connecting rod 513 to synchronously drive the second auger shaft 511 to rotate through the meshing of two bevel gears 514. The rotation of the second auger shaft 511 drives several paddles 512 to rotate. The rotation of the second auger shaft 511 spirally conveys the feed in the storage tank 3, and the paddles 512 paddle and discharge the conveyed feed.

[0026] S3. Uniform feed feeding: When the mixing and feeding mechanism 5 feeds the feed in a straight line along with the tractor, the corresponding mixing and feeding mechanism 5 is simultaneously linked with the uniform spreading mechanism 6 to surround and spread the feed area evenly. The specific steps are as follows: When the paddle 512 pushes the mixed feed to feed, the feed will be placed into the area protected by the enclosure frame 601. The enclosure frame 601 moves in a straight line with the tractor. The scraper 602 in the enclosure frame 601 will scrape the top of the feed stack to make up for the small amount of feed feeding area. During the rotation of the second auger shaft 511, the second auger shaft 511 synchronously drives the first circular plate 604 to rotate. The first circular plate 604 and the second circular plate 605 are connected by the misalignment of the semi-circular protrusion 606, which causes the second circular plate 605 to move back and forth. The back and forth movement of the second circular plate 605 drives the mounting plate 603 and the feeding rod 607 to move back and forth. The back and forth movement of the feeding rod 607 will push left and right, thereby pushing and spreading the scraped feed horizontally and quickly.

[0027] S4. Feeding route cleaning: While the mixing and feeding mechanism 5 and the even spreading mechanism 6 are simultaneously mixing and feeding and feeding evenly, they will also drive the feeding cleaning mechanism 7 to clean the area to be fed, removing debris and old feed. The specific steps are as follows: When the second auger shaft 511 rotates to drive the feed transmission, the second auger shaft 511 synchronously drives the second pulley 704 and the second belt 705 to cooperate in transmission, causing the rotating roller 702 to drive the brush layer 703 to clean up debris and old feed on the route to be fed, leaving a clean feeding space.
