[0016] (1) By setting up a feeding auger, a drive motor, a fixed cover, a transmission chain, a transmission sprocket, a fixed plate, a support ring, an arc plate, a fixed disc, and balls, when the material is introduced into the feeding pipe, the drive motor is started to drive a set of transmission sprockets to rotate, and the transmission chain drives two sets of feeding augers to rotate synchronously.

[0026] The feeding mechanism includes a feeding auger 2. The feeding auger 2 is movably connected to both ends of one side of the feeding pipe 1. A fixed plate 20 is fixedly connected to one side of the feeding auger 2. A fixed plate 17 is fixedly connected to one side of the top end of the feeding pipe 1.

A drive motor 8 is fixedly connected to one side of the fixed cover 9.
[0027] The output end of the drive motor 8 extends into the interior of the fixed cover 9 and is fixedly connected to the transmission sprocket 11; the feeding auger 2 extends into the interior of the fixed cover 9 and is fixedly connected to the transmission sprocket 11.
[0028] The centerline of the arc plate 19 and the centerline of the feeding tube 1 are on the same vertical plane, and the ball bearing 21 is movably connected to the support ring 18.
[0029] The centerline of the feeding auger 2 is on the same horizontal plane as the centerline of the transmission sprocket 11, and the centerline of the feeding auger 2 is on the same horizontal plane as the centerline of the fixed disc 20;
[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, during feeding, after the material is introduced into the feeding pipe 1, the drive motor 8 is started to drive a set of transmission sprockets 11 to rotate, and through the transmission chain 10, it drives two sets of feeding augers 2 to rotate synchronously. While the feeding augers 2 are rotating, they can spread the material evenly and feed it out at a uniform speed. The support ring 18 installed at the bottom of the fixed plate 17 on one side of the feeding pipe 1 is sleeved on the outside of the fixed plate 20 to support the feeding augers 2, ensuring the stability of the feeding augers 2 and reducing the wear rate, thus ensuring a uniform feeding speed.
[0031] The feed pipe 4 is fixedly connected to both sides of the fixed frame 3, the fixed frame 3 is movably connected to the inside of the fixed frame 3, and the fixed frame 3 is fixedly connected to one side of the fixed frame 3.
[0032] The fixed frame 3 is connected to the inside of the feed pipe 4, and the output end of the cylinder 7 extends into the inside of the fixed frame 3 and is fixedly connected to the movable baffle 6.
[0033] Specifically, such as Figure 1 and Figure 3 As shown, during feeding, the material is first introduced through the feed hopper 5, and then the cylinders 7 on both sides are started. The cylinders 7 simultaneously push the movable baffles 6 on both sides to move, so as to quickly adjust the distance between the two sets of movable baffles 6. Adjusting the movable baffles 6 to a suitable distance can adjust the feeding speed. When the material passes through the inside of the feed pipe 4, the movable baffles 6 control the feeding speed, thus realizing convenient control of the feeding speed.
[0034] A hydraulic cylinder 15 is fixedly connected to the top of the base plate 13, a limiting cylinder 14 is fixedly connected to the bottom of the feeding pipe 1, limiting posts 12 are fixedly connected to both sides of the bottom of the feeding pipe 1, and a fixing cylinder 16 is fixedly connected to both sides of the top of the base plate 13.

[0037] Working Principle: In use, this device is moved to the side of the preparation equipment. Then, the hydraulic cylinder 15 at the top of the base plate 13 is activated. The hydraulic cylinder 15 pushes the feeding pipe 1 up, adjusting it to a suitable height level with the feed inlet of the preparation equipment. The limiting post 12 at the bottom of the feeding pipe 1 fits inside the fixed cylinder 16, limiting the feeding pipe 1 to ensure its stability and prevent wobbling. During feeding, the material is first introduced through the feed hopper 5, then the cylinders 7 on both sides are activated. The cylinders 7 simultaneously push the movable baffles 6 on both sides to move, quickly adjusting the distance between the two sets of movable baffles 6. The distance between the movable baffles 6 and the feed speed can be adjusted by adjusting the movable baffles 6 to a suitable distance. When the material passes through the inside of the feed pipe 4, the movable baffles 6 control the feed speed. When feeding, after the material is introduced into the feed pipe 1, the drive motor 8 is started to drive a set of transmission sprockets 11 to rotate, and through the transmission chain 10, it drives two sets of feeding augers 2 to rotate synchronously. While the feeding augers 2 are rotating, they can spread the material evenly and feed it out at a uniform speed. The support ring 18 installed at the bottom of the fixed plate 17 on one side of the inside of the feed pipe 1 is sleeved on the outside of the fixed plate 20 to support the feeding augers 2, ensuring the stability of the feeding augers 2 and reducing the wear rate.
