[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, an embodiment of the present invention discloses a straw crusher, including a crushing box 1, a cover plate 2 that is rotatably mounted on the upper end of the crushing box 1 via a hinge, support seats 4 installed at both ends of the crushing box 1, a dust collection assembly 3 installed inside the crushing box 1, a box body 5 installed at one end of the crushing box 1, a fan 7 installed at the upper end of the box body 5, a rigid pipe 8 connected to the suction end of the fan 7, the rigid pipe 8 connected to the crushing box 1, a corrugated pipe 9 connected to the end of the rigid pipe 8, a suction head 10 installed at the end of the corrugated pipe 9, a filter plate 11 installed on the suction head 10 by bolts, rotating rods 12 rotatably connected inside the crushing box 1, crushing blades 13 installed on the outer surface of both rotating rods 12, rotating gears 14 installed at one end of both rotating rods 12, a drive motor 15 installed at one end of the crushing box 1, and the output shaft of the drive motor 15 connected to one of the... The rotating rods 12 are connected together. Two through holes 16 are opened at the bottom of the box body 5. The collection box 19 slides inside the box body 5. Support legs 17 are installed on both sides of the bottom end of the collection box 19. Rollers 18 are installed at the bottom end of the two support legs 17. The box body 5 is equipped with a limiting component 6. The rotating rods 12 rotate to drive the crushing blades 13 to rotate and crush the straw. The dust attached to the straw in the crushing box 1 can be adsorbed by the fan 7, rigid pipe 8, corrugated pipe 9 and suction head 10. With the dust suction component 3, the dust suction position can be adjusted. The cover plate 2 can be opened to facilitate the disassembly and assembly of the filter plate 11 to avoid clogging and affecting the subsequent dust removal effect. The dust is then sent into the collection box 19. The limiting component 6 can limit the collection box 19 to ensure the stability of dust collection.

[0025] The dust collection assembly 3 includes two guide plates 31 installed inside the pulverizing chamber 1. Each guide plate 31 has a slider 32 slidably connected to it. Both sliders 32 are connected to the suction head 10. A lead screw 33 is rotatably connected inside the pulverizing chamber 1. The lead screw 33 is threadedly connected to one of the sliders 32. A servo motor 34 is installed at one end of the pulverizing chamber 1. The output shaft of the servo motor 34 is connected to the lead screw 33. The servo motor 34 drives the lead screw 33 to rotate, which in turn drives the slider 32 to slide on the guide plate 31, thereby adjusting the dust collection position and making the internal dust removal more thorough.

[0026] like Figure 4 As shown, in some embodiments, the limiting component 6 includes fixed seats 61 installed at both ends of the housing 5. Each fixed seat 61 is equipped with a sliding rod 62. A baffle 63 is slidably connected between the two sliding rods 62. A handle 64 is installed at one end of the baffle 63. Springs 65 are installed on both sides of the upper end of the baffle 63. The two springs 65 are respectively connected to the two fixed seats 61. By pulling up the handle 64, the baffle 63 slides up on the sliding rod 62 and compresses the springs 65, thereby no longer limiting the collection box 19. That is, the collection box 19 slides out of the through hole 16 through the support leg 17, and the dust collected inside the collection box 19 can be transferred.

[0027] like Figure 1 As shown, in some embodiments, the baffle 63 has a U-shaped structure and abuts against the collection box 19; the structure is simple.

[0028] like Figure 1 As shown, in some embodiments, the support leg 17 is located within the through hole 16 for easy guidance.

[0029] like Figure 2 As shown, in some embodiments, the two rotating gears 14 mesh with each other; this facilitates crushing.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
