The crushing mechanism 100 includes a crusher body 110 and a feeding channel 120 connected to and communicating with the crusher body 110.

[0030] The pressing mechanism 200 comprises two horizontal frames 210 installed on one side of the feeding channel 120, a motor 220 connected between the two horizontal frames 210, a rubber pressing plate 230 sleeved on the outside of the output shaft of the motor 220, a roller 240 movably arranged in the feeding channel 120, and a motor 250 connected between the feeding channel 120 and the roller 240.

[0031] The dust blocking mechanism 300 comprises a supporting plate 310 connected to the top of the crusher main body 110, two T-shaped rods 320 movably inserted into the supporting plate 310, a cover plate 330 connected between the two T-shaped rods 320, a spring 340 connected between the supporting plate 310 and the cover plate 330, an inclined plate 350 installed on the back side of the cover plate 330, a pressing plate 360 sleeved on the outside of the output shaft of the motor 220 and abutting against the inclined plate 350, and the bottom of the cover plate 330 movably abutting against the top of the feeding channel 120.

[0032] Further, the spring 340 is movably sleeved on the outside of the T-shaped rod 320, and the diameter of the spring 340 is smaller than the thickness of the cover plate 330. With the layout and size design, the spring 340 can stably extrude the cover plate 330, and the probability of deformation is reduced.

[0033] Further, the inclined plate 350 is arranged in an inclined manner, and both ends are arranged as arc surfaces. The layout and shape of the inclined plate 350 are designed so that the pressing plate 360 can easily extrude the inclined plate 350. Embodiment Two

[0034] In combination with Figures 1-3 and Figure 5 shown in Embodiment One, on the basis of Embodiment One, a notch is formed at the top end of the feeding channel 120, and the notch is located between the two horizontal frames 210. The notch provides a condition for the rubber pressing plate 230 to enter the feeding channel 120.

[0035] Further, one end of the rubber pressing plate 230 movably penetrates the notch and extends into the feeding channel 120. With this structure design, it is ensured that the rubber pressing plate 230 can press the straw into the feeding channel 120. Embodiment Three

[0036] In combination with Figure 1 and Figure 5As shown in the above embodiment, the bottom of the feeding channel 120 is provided with a dust collection mechanism 400, which includes a filter screen plate 410 embedded in the bottom of the feeding channel 120, a shell sleeve 420 sleeved on the bottom of the feeding channel 120, and a shell cover 430 inserted with the shell sleeve 420.
