[0001] The utility model relates to the technical field of crushers, in particular to an oat crusher with a vibrating screen structure. Background Art

[0002] Oats are a low-sugar, high-nutrition, high-energy food. Oats are sweet and mild in nature, can nourish the spleen and heart, and can reduce sweating. They have high nutritional value. Oats contain oat protein, oat peptides, oat beta glucan, oat oil and other ingredients. They have antioxidant effects, increase skin activity, delay skin aging, whiten and moisturize, reduce wrinkles and spots, and have anti-allergic effects. Therefore, using oats as raw materials, crushing, sieving, and extracting effective ingredients can effectively improve the economic role of oats.

[0003] After searching, the application number CN202320907715.X discloses a vibrating screening device with a crushing structure, a feeding hopper is arranged on the device, and a first vibrating mesh screen and a second vibrating mesh screen are arranged inside the device, the first vibrating mesh screen is arranged above the second vibrating mesh, and a first material guide frame is connected to the right side of the device body, and a conveyor belt device is arranged at the lower right of the first material guide frame. A collecting box is arranged throughout the device body.

[0022] See also Figure 1-Figure 5 The oat crusher with a vibrating screen structure provided by the utility model includes a crusher 1, a crushing assembly 2, a conical driving gear ring 3 and a vibrating screen 4.

[0023] Among them, see Figure 1-Figure 3 The crusher 1 includes a crusher body 12, a feed port 11 is provided on the top of the crusher body 12, a discharge port 15 is provided on the bottom of the crusher body 12, a crushing assembly 2 is installed at the top center of the crusher body 12, the lower end of the crushing assembly 2 penetrates the crusher body 12 and extends to the inner cavity of the crusher body 12, a mounting groove 13 is provided on the inner wall of the crusher body 12, a vibrating screen 4 is slidably connected in the mounting groove 13, an elastic support pad 14 is fixedly connected to the bottom of the mounting groove 13, the upper end surface of the elastic support pad 14 is fixedly connected to the lower end surface of the vibrating screen 4, a conical drive gear ring 3 is arranged in the adjacent area of ​​the crushing assembly 2 and the vibrating screen 4, the outer wall of the conical drive gear ring 3 is fixedly connected to the inner wall of the crusher body 12, the crushing assembly 2 and the conical drive gear ring 3 cooperate to revolve and rotate at the same time, so as to grind and crush the oats on the upper end of the vibrating screen 4, and the crushing assembly 2 periodically drives the vibrating screen 4 to vibrate when rotating, so as to promote the screening of the crushed oats.

[0024] It should be noted that a tooth groove is formed on the upper end surface of the conical driving gear ring 3 .

[0025] It should also be noted that the outer diameter of the vibration screen 4 is equal to the inner diameter of the elastic support pad 14, which improves the stability of the vibration screen 4 moving in the elastic support pad 14 and prevents the vibration screen 4 from escaping from the elastic support pad 14 when moving.

[0026] It should be added that the vibrating screen 4 includes a mounting ring and a screen. The screen is a metal screen with supporting force, and the diameter of the screen is equal to the inner diameter of the crusher body 12 to prevent oat particles from being deposited in the mounting groove 13 during screening.

[0027] For details, please refer to Figure 4 and Figure 5 In order to improve the uniformity of oat crushing, the crushing assembly 2 includes a driving motor 21, which is installed on the top of the crusher body 12. The output end of the driving motor 21 is fixedly connected to a driving rod 22, which extends into the inner cavity of the crusher body 12. The side wall of the lower end of the driving rod 22 is rotatably connected with three groups of crushing rods 23. The driving motor 21 drives the crushing rod 23 to revolve through the driving rod 22 to grind and crush the oats on the upper end of the vibrating screen 4. The crushing rod 23 includes a rotating shaft 232, which is rotatably connected to the side wall of the driving rod 22. A crushing roller 231 is fixedly connected to the outer wall of the rotating shaft 232. A plurality of groups of crushing teeth 233 are distributed in an array on the outer wall of the crushing roller 231. The crushing teeth 233 can improve the grinding and crushing efficiency of the crushing roller 231. A conical driving gear 235 is fixedly connected to the end of the rotating shaft 232 away from the driving rod 22. The conical driving gear 235 and the conical driving gear ring 3 are connected. The wheels are engaged, and when the rotating shaft 232 follows the driving rod 22 to revolve, the conical driving gear 235 is engaged with the conical driving gear ring 3, so that the rotating shaft 232 rotates, and the rotating shaft 232 drives the crushing roller 231 to rotate to improve the grinding efficiency of the oats. The outer wall of the crushing roller 231 is fixedly connected to the side close to the conical driving gear 235. The connecting rod 234 follows the rotation of the crushing roller 231. When the connecting rod 234 moves to the bottom, it pushes the vibrating screen 4 to compress the elastic support pad 14 downward to move. After the connecting rod 234 moves away, the elastic support pad 14 pushes the vibrating screen 4 to reset, and the vibrating screen 4 cooperates with the crushing roller 231 to grind and crush. As the crushing roller 231 rotates, the vibrating screen 4 vibrates up and down periodically, thereby screening the oats on the upper end of the vibrating screen 4, and timely screening out the completely crushed ground oats, thereby improving the crushing efficiency of the remaining oats, while avoiding excessive grinding of the oats, resulting in agglomeration and uneven particles.

[0028] It should be noted that the end of the connecting rod 234 away from the crushing roller 231 is set to be spherical, so as to reduce the damage to the vibrating screen 4 when the connecting rod 234 is pushed.

[0029] It should also be noted that during grinding, the elastic support pad 14 supports the vibrating screen 4, the vibrating screen 4 is in contact with the crushing roller 231 and always maintains a suitable grinding pressure. During screening, the connecting rod 234 pushes the vibrating screen 4 to squeeze the elastic support pad 14 to deform, and the upper end surface of the vibrating screen 4 is temporarily separated from the crushing roller 231. At the same time, the vibrating screen 4 vibrates to accelerate the screening of broken oats.

[0030] Principle: Oats are put into the feed port 11, and enter the inner cavity of the crusher body 12 and stay on the upper end surface of the vibrating screen 4. The driving motor 21 drives the crushing rod 23 to revolve through the driving rod 22. When the crushing rod 23 revolves, the oats on the upper end of the vibrating screen 4 are ground and crushed. At the same time, the rotating shaft 232 revolves with the driving rod 22, and the conical driving gear 235 cooperates with the conical driving gear ring 3 to make the rotating shaft 232 rotate. The rotating shaft 232 drives the crushing roller 231 to rotate. The crushing roller 231 rotates with the rotating shaft 232. The crushing teeth 233 distributed on the outer wall of the crushing roller 231 can improve the crushing efficiency of the oats. The connecting rod 234 follows the rotation cycle of the crushing roller 231 to push the vibration screen 4 to compress the elastic support pad 14 and vibrate up and down along the inner wall of the installation groove 13. When the vibration screen 4 vibrates, the completely crushed oats are screened out, and the crushing efficiency of the oats that are not completely crushed on the upper end surface of the vibration screen 4 is accelerated to avoid agglomeration or inactivation of effective ingredients caused by excessive grinding. The qualified crushed oats are screened by the vibration screen 4 and finally discharged from the discharge port 15.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
