[0002] Fattening cattle, also known as beef cattle, are a type of cattle primarily raised for beef production. Beef cattle are characterized by their full-bodied build, rapid weight gain, high feed utilization, good meat production performance, and excellent meat quality and taste. Feed additives refer to small or trace amounts of substances added during feed production, processing, and use. They are used in very small quantities but have significant effects. Feed additives are essential raw materials used in the modern feed industry, and they have significant effects on enhancing the nutritional value of basic feeds, improving animal production performance, ensuring animal health, saving feed costs, and improving the quality of livestock products. Drying equipment is required during the production of feed additives.

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0039] like Figures 1-7 As shown, a feed additive drying device includes an outer shell 1. A partition plate 101 and a partition plate 102 are fixedly mounted sequentially from top to bottom on the inner side of the outer shell 1. Three drying chambers 8 are arranged around the centerline of the outer shell 1 between the partition plate 102 and the partition plate 101. A drive assembly 10 is disposed between the inner bottom surface of the outer shell 1 and the partition plate 102. The drive assembly 10 is connected to a discharge pipe 5 fixed to the bottom of the drying chamber 8. The drive assembly 10 includes a driven gear 1002, which is sleeved on the outside of the discharge pipe 5 and meshes with a drive gear 1001. The drive gear 1001 is connected to a sleeve... The sleeve 11 has a connecting rod 1101 fixed at its top end, which passes through the center of the rotating connecting partition plate 101. The connecting rod 1101 is connected to the drive assembly 7, which is installed in the mounting shell 2 at the top of the outer shell 1. The drive assembly 7 includes a drive wheel 702, and a synchronous belt sleeved on the outside of the drive wheel 702 drives and connects to the driven wheel 701. The driven wheel 701 is connected to the driven wheel 704. The driven wheel 704 is connected to the stirring assembly 9 installed in the drying oven 8. The stirring assembly 9 includes a helical gear 901, which meshes with the helical gear 902. The shaft of the helical gear 902 is connected to the stirring rod 903.

[0040] The top of the drying oven 8 is rotatably connected to the partition plate 101, and the top of the drying oven 8 is fitted with an installation ring 801.

A drying assembly is disposed inside the placement shell 4. The drive gear 1001 is located at the center of the inner bottom surface of the outer shell 1 and transmits power through the sleeve 11 to ensure the stable rotation of the drying chamber 8. The exhaust holes on the side of the sleeve 11 allow the hot air generated by the drying assembly inside the placement shell 4 to enter the outer shell 1 evenly to heat the outside of the drying chamber 8.

[0043] Three sets of driven wheels 704 are rotatably mounted on the inner bottom surface of the mounting shell 2, and the three sets of driven wheels 704 correspond to the three sets of drying chambers 8. The driven wheels 704 are coaxial with the center of the drying chambers 8. The driven wheel 701 is mounted on the top surface of one set of driven wheels 704 via a mounting rod. The three sets of driven wheels 704 are driven by a synchronous belt 2 sleeved on the outer side. The top of the driving wheel 702 is connected to the output shaft of the motor 14 fixed at the center of the top surface of the stirring assembly 9. The bottom of the driving wheel 702 is fixed with a movable rod that passes through and rotatably connects to the bottom surface of the mounting shell 2, and the bottom of the movable rod is fixed with an insert rod 703. The insert rod 703 is a cuboid and slides into a slot opened at the center of the top surface of the connecting rod 1101. The driven wheels 704 are coaxial with the drying chambers 8 and are driven by the synchronous belt 2, ensuring that the stirring assemblies 9 in the three sets of drying chambers 8 operate synchronously.

[0044] A rotating rod is fixed at the center of the bottom end of the driven wheel 704, and the rotating rod passes through and is rotatably connected to the bottom surface of the mounting shell 2. A protective shell is fitted on the outer side of the end of the rotating rod. A helical gear 901 is rotatably mounted on the inner bottom surface of the protective shell and meshes with the helical gear 902. The shaft of the helical gear 902 passes through and is rotatably connected to both sides of the protective shell. A dynamic sealing ring is fitted at the connection between the shaft of the helical gear 902 and the protective shell. The stirring rod 903 connected to the shaft of the helical gear 902 has an arc-shaped end that fits against the inner wall of the drying chamber 8. The two sets of stirring rods 903 are arranged vertically and staggered. The rotation direction of the drying chamber 8 is opposite to the stirring direction of the stirring assembly 9. The two sets of vertically staggered stirring rods 903 stir the additive at multiple angles. The arc-shaped end design fits against the inner wall of the drying chamber 8 to prevent material residue. The drying chamber 8 and the stirring assembly 9 move in opposite directions to increase the contact area between the material and the hot air.

[0045] The drying assembly includes a fan 13. The bottom of the placement shell 4 has a through-hole for installation, and a dust filter plate is fixed inside the installation window. The fan 13 is fixed at the center of the top surface of the dust filter plate. An electric heating wire 12 is arranged above the fan 13 and is installed inside the placement shell 4. The mounting shell 2 has three sets of feeding hoppers 3 arranged around the center line. The feeding hoppers 3 are correspondingly arranged above the eccentric part of the top surface of the drying oven 8. The outer shell 1 and the mounting shell 2 are connected by a flange. The fan 13 and the electric heating wire 12 combine to generate stable hot air, which is evenly sent into the outer shell 1 through the exhaust hole of the sleeve 11.

[0046] The top surface of the mounting shell 2 is equipped with a controller, which contains a PLC microcontroller, a relay module, and a control switch. The controller is electrically connected to the mounting shell 4, the electric heating wire 12, and the fan 13.

[0047] The working principle and usage process of this utility model are as follows: When using this device, the user pours the feed additives to be dried into the three sets of drying chambers 8 through the feeding hopper 3. Then, the controller drives the motor 14, which drives the drive wheel 702 to rotate through the output shaft. The drive wheel 702 drives the driven wheel 701 through the synchronous belt, which in turn drives the driven wheel 704 to rotate. The rotating 704 drives the other two sets of 704 to rotate synchronously through the synchronous belt, thereby driving the turning assembly 9 to work. While the drive wheel 702 is rotating, the insert rod 703 at the bottom of the drive wheel 702 drives the connecting rod 1101 and the sleeve 11 to rotate. The drive gear 1001 on the sleeve 11 meshes with the driven gear 1002, causing the drying chamber 8 to rotate around its own axis. The drying chamber 8 and the turning assembly 9 move in opposite directions. After the driven wheel 704 rotates, the rotating rod fixed at the center of its bottom end drives the helical gear 901 inside the protective shell to rotate. 01 meshes perpendicularly with helical gear 902, transmitting power to helical gear 902. The two sets of vertically intersecting stirring rods 903 connected to the shaft of helical gear 902 then begin to rotate. The ends of the stirring rods 903 are arc-shaped, closely fitting the inner wall of the drying chamber 8. During rotation, they can not only stir the feed additives from all directions and angles, scrape off the material adhering to the inner wall of the drying chamber 8 to prevent material residue, but also cooperate with the reverse rotation of the drying chamber 8 to subject the feed additives to greater shearing and frictional forces inside the drying chamber 8, further increasing the contact area between the material and the hot air, accelerating moisture evaporation, and improving drying efficiency and quality. The electric heating wire 12 and fan 13 placed inside the shell 4 are activated. The fan 13 blows the hot air generated by the electric heating wire 12 into the outer shell 1 through the exhaust hole on the side of the sleeve 11 to heat the outside of the drying chamber 8. At the same time, the hot air enters the drying chamber 8 and comes into full contact with the feed additives that are constantly being turned over by the stirring assembly 9.

[0048] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that is used for control, and the existing publicly available power connection technology will not be elaborated in the text.
