[0022] The following is combined with Figure 1-5 The utility model is further described in detail:

[0023] The utility model embodiment discloses a corncob crushing blade, such as Figure 1 As shown, a corn cob crushing blade comprises a connecting portion 1, wherein a connecting hole 2 is provided inside the connecting portion 1; the connecting portion 1 is integrally formed with an extension portion 3 extending from the center to the opposite sides outward; the extension portion 3 is integrally formed with a crushing portion 5 and an anti-stuck portion 4 in a "Y" shape on one side away from the connecting portion 1; the utility model solves the problem that the blade of the prior art crusher is easily stuck by the corn cob by adding the crushing portion 5 and the anti-stuck portion 4, and the corn cob is continuously moved and assisted in cutting by the anti-stuck portion 4, so that the blade is prevented from being stuck by the corn cob fragments, thereby ensuring the normal operation of the motor, extending the service life, and further improving the crushing efficiency;

[0024] like Figure 1 , Figure 3 As shown, the anti-stuck portion 4 is formed by extending in the same plane as the extension portion 3; the crushing portion 5 is formed by extending the extension portion 3 in an oblique upward direction; the angle between the projections of the crushing portion 5 and the anti-stuck portion 4 on the same plane is α, 10°≤α≤45°; in this embodiment, the anti-stuck portion 4 is a straight structure consistent with the extension portion 3. While playing the crushing function, when the corn cob enters the crushing bin 62, the straight anti-stuck portion 4 can push it directly to the center of the crushing chamber, ensuring that the material can be stably pushed to the rotation center of the blade, avoiding the corn cob fragments from being stuck in the gap between the blade and the crushing bin 62; avoiding flying around or getting stuck in the crushing chamber; the design of the crushing portion 5 is the key, and it can use its oblique upward tilted shape to guide the material from the center to the outside of the blade. As the blade rotates, these materials will be gradually thrown out and further crushed by the downward gravity. This design can ensure that the material always moves along a continuous and stable path, improving the crushing efficiency while reducing the machine jam caused by material accumulation or jamming;

[0025] like Figure 1 , Figure 2 As shown, the angle between the crushing part 5 and the extension part 3 is β, 90°≤β≤120°; in this embodiment, the producer controls the angle between the crushing part 5 and the extension part 3, because if the tilting angle is too large, the effect of guiding the material to be thrown out will be stronger, which is helpful to improve the crushing efficiency, but too large an angle may also cause some materials to be thrown out prematurely, affecting the crushing effect; if the tilting angle is too small, the effect of guiding the material will be weakened, which may cause some materials to accumulate in the crushing chamber, increasing the risk of jamming; in order to find a balance between efficiency and effect, the producer needs to carefully adjust and test the tilting angle;

[0026] like Figure 2As shown, the crushing portion 5 and the extension portion 3 are transitioned by an arc angle; in this embodiment, the arc angle can improve the structural strength and reduce the cleaning dead angle;

[0027] like Figure 4 , Figure 5 As shown, a crushing device includes a body 6, a base 61, and a crushing bin 62. The body 6 is installed on the top of the base 61, and the crushing bin 62 is installed on the top of the body 6. The crushing bin 62 is provided with an output end extending from the driving member in the body 6; the character is that any one of the above-mentioned corn cob crushing blades is installed in the crushing bin 62; the distance between the crushing part 5, the anti-stuck part 4 and the inner wall of the crushing bin 62 is C mm, C≤2; in this embodiment, the corn cob is put into the crushing bin 62, and a button for control is provided on the base 61. After it is turned on, the driving member in the body 6 starts the crushing operation. The blade provided by the utility model can prevent the corn cob from being stuck during crushing to the greatest extent, thereby improving the crushing efficiency and protecting the normal operation of the driving member.

[0028] In addition, it is worth noting that the distance between the crushing part 5, the anti-stuck part 4 and the inner wall of the crushing bin 62 is C mm, C≤2; stipulating the maximum distance between the blade and the crushing bin 62 can effectively avoid the problem of corn cob getting stuck due to excessive spacing between the parts.
