DETAILED DESCRIPTION

[0030] The present application will be further described in detail below in combination with examples: Example 1

[0031] As Figures 1-6As shown, this invention provides a granulation device for preparing biological feed, including a granulation cylinder 1, suitable for granulation in biological feed preparation. A base 2 is disposed below the granulation cylinder 1, and a heat insulation cover 3 is detachably fitted onto the outer surface of the base 2. Support legs 4 are fixedly connected to the bottom perimeter of the base 2. An extrusion unit is disposed at the top of the granulation cylinder 1, a cutting unit is disposed on the outer surface of the granulation cylinder 1, a drying unit is disposed at the bottom of the granulation cylinder 1, and a screening unit is disposed below the drying unit, located inside the bottom of the base 2. The outer surface of the granulation cylinder 1 is located on the frame plate. The granulation cylinder 1 has a granulation hole 11 inside. A drive rod 12 is fixedly connected to the bottom end of the granulation cylinder 1. The other end of the drive rod 12 passes through the middle of the support plate 14 and extends to the bottom end of the support plate 14. A drive motor 13 is fixedly connected to the other end of the drive rod 12. The cutting unit includes a curved support rod 156 fixedly installed around the top of the support ring seat 15. A sleeve 157 is fixedly sleeved on the outer surface of the other end of the curved support rod 156. A scraper 158 is fixedly connected to the inner side of the sleeve 157. The scraper 158 is attached to the outer surface of the granulation cylinder 1.

[0032] Furthermore, by pouring feed ingredients into the inside of the pelleting cylinder 1, the ingredients accumulate downwards and flow out of the pelleting cylinder 1 through the pelleting holes 11. At this time, with the start of the drive motor 13, the output end of the drive motor 13 drives the drive rod 12 to rotate at a constant speed. The constant speed rotation of the drive rod 12 causes the pelleting cylinder 1 to rotate accordingly. When the ingredients inside the pelleting holes 11 flow outwards, they are scraped off by the scraper plates 158 around the perimeter, cutting the feed and enabling the feed ingredients to be pelleted quickly. Example 2

[0033] like Figures 1-6 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the extrusion unit includes an electric telescopic column 17 disposed around the top of the support ring seat 15, a support crossbar 18 fixedly connected to the top of the electric telescopic column 17, an extrusion rod 19 fixedly connected to the bottom middle position of the support crossbar 18, an extrusion disc 110 fixedly connected to the bottom end of the extrusion rod 19, and the extrusion disc 110 slidably connected to the inner wall of the granulation cylinder 1.

[0034] Furthermore, by retracting the electric telescopic column 17 downwards, the extrusion rod 19 causes the extrusion disc 110 to move down onto the inner wall of the pelleting cylinder 1, extruding the feed raw materials inside the pelleting cylinder 1, causing the raw materials to flow out of the pelleting holes 11, promoting smooth flow, and at the same time, the pressure caused by the extrusion makes the pellets fuller. Example 3

[0035] like Figures 1-6As shown, based on embodiments 1-2, the present invention provides a technical solution: preferably, a guide plate 111 is provided on the outer surface of the drive rod 12, a guide channel 112 is opened on the outer surface of the guide plate 111, a spiral guide groove 113 is provided on the bottom end of the guide channel 112, a sealing cover plate 114 is fixedly connected to the side frame plates of the guide channel 112, an arc-shaped air blocking plate 115 is fixedly connected to the top inner wall of the sealing cover plate 114, and an exhaust hole 116 is opened inside the arc-shaped air blocking plate 115.

[0036] Furthermore, by setting the guide plate 111 at the bottom of the granulation cylinder 1, the impact force of the falling particles is reduced, preventing them from deforming or cracking. The feed particles cut by the scraper 158 gradually roll downwards along the inclined angle of the surrounding guide channels 112. During the rolling process, the feed particles gradually become rounded. The spiral guide channel 113 slows down the rolling speed of the feed particles, increasing the contact time between the feed particles and the heat. When the hot air enters the interior of the guide channel 112, the sealing cover plate 114 seals the guide channel 112, causing the hot air to condense. The air enters the guide channel 112 and impacts the arc-shaped air baffle plate 115. The impact force causes the hot air to flow downwards and spray into the interior of the spiral guide channel 113, improving the contact with the feed particles and enhancing the drying efficiency. Example 4

[0038] Furthermore, by activating the heater 151, the intake air is heated and then guided into the interior of the spray plate 154 through the air guide pipe 153. The air is then evenly sprayed outward by the atomizing nozzle 155. The hot air is enveloped inside the heat insulation cover 3. As the hot air gradually increases, it flows upward along the outflow groove 16 and reaches the guide plate 111, where it is heated. The temperature of the guide plate 111 gradually increases. When the feed pellets roll inside the guide channel 112, the outer surface of the feed pellets comes into contact with the guide channel 112 and is heated, drying the internal moisture. Example 5
