[0029] Example 1

[0030] like Figures 1 to 3 As shown, a dry ice crushing mechanism includes a base 1, a filter mechanism, an ice crushing mechanism, a drive mechanism, and a transmission mechanism. The base 1 is provided with a filter mechanism, which in turn has an ice crushing mechanism. A drive mechanism is provided on one side of the base 1 and is connected to the filter mechanism via a transmission mechanism. The drive mechanism is used to drive the ice crushing mechanism to rotate or swing within the filter mechanism. In this embodiment, the filter mechanism is detachably connected to the base 1. The ice crushing mechanism is used to crush the dry ice into particles of a certain coarseness. The granulated dry ice is filtered through the filter mechanism and then leaves the base 1. The drive mechanism is used to drive the rotation of the ice crushing mechanism, and the transmission mechanism is used to connect the drive mechanism and the ice crushing mechanism.

[0031] Furthermore, as a preferred embodiment, the middle portion of the base 1 is tilted inward from top to bottom, and a dry ice inlet hole 2 is provided in the middle portion of the base 1. The filter mechanism is disposed within the dry ice inlet hole 2. A clearance groove 3 is provided on one side of the base 1, and the transmission mechanism is located within the clearance groove 3. In this embodiment, the base 1 is an annular columnar structure, with the middle portion of the base 1 tilted downward, and ice enters the dry ice inlet hole 2 with the ice, and then enters the filter mechanism through the dry ice inlet hole 2.

[0032] Furthermore, as a preferred embodiment, the filter mechanism includes a cylindrical body 4 and a filter 5 disposed at the bottom of the cylindrical body 4. The ice crushing mechanism is rotatably mounted above the filter 5. A dry ice inlet 6 is formed in the sidewall of the cylindrical body 4 and communicates with the dry ice inlet 2. In this embodiment, the filter mechanism is cylindrical in shape, open at one end and closed at the other. The dry ice inlet 6 in the sidewall facilitates the entry of dry ice. The upper sides of the two side walls of the dry ice inlet 6 are designed with a wavy structure to cooperate with ice crushing blades 8 to quickly crush the dry ice. When the ice crushing blades 8 cut the dry ice, some of the dry ice becomes trapped within the wavy structure, facilitating the partial crushing of the dry ice particles. In this embodiment, the sidewalls of the cylindrical body 4 are connected to the sidewalls of the dry ice inlet 2 and can be secured by a sleeve with a screw. The bottom of the cylindrical body 4 is provided with a through hole for the dry ice particles to exit, and the filter 5 covers the through hole.

[0033] Furthermore, as a preferred embodiment, the ice-crushing mechanism includes a connecting shaft 7 and a plurality of ice-crushing blades 8 disposed on the outer circumference of the connecting shaft 7. One end of the connecting shaft 7 is rotatably connected to the inner wall of one end of the cylindrical body 4. The other end of the connecting shaft 7 extends out of the cylindrical body 4 and is connected to a drive mechanism via a transmission mechanism. In this embodiment, the drive mechanism is a cylinder 23, which is used to drive the connecting shaft 7 in forward and reverse rotation. The connecting shaft 7 drives the ice-crushing blades 8 in forward and reverse rotation to crush the dry ice. The shapes of the ice-crushing blades 8 in this embodiment include, but are not limited to, diamond, triangle, olive, or elliptical shapes.

[0034] Furthermore, as a preferred embodiment, the transmission mechanism includes a sleeve 9, a gear 10, and a rack 11. The sleeve 9 and gear 10 are sequentially sleeved on the other end of the connecting shaft 7. The connecting shaft 7 is rotatably connected to the inner wall of the base 1 via the sleeve 9. The rack 11 is located within the clearance groove 3 and meshes with the gear 10. One end of the rack 11 is connected to the drive mechanism. In this embodiment, the connecting shaft 7 is fixed within the cylindrical body 4 via the sleeve 9. The ice crusher 8 rotates within the filter mechanism driven by the connecting shaft 7. The cylinder 23 pushes the rack 11 in reciprocating linear motion. The rack 11 drives the gear 10 in forward and reverse rotational motion. The gear 10 drives the ice crusher 8 in forward and reverse motion, thereby facilitating the crushing of dry ice particles into fine particles for filtration through the filter 5.

[0035] Example 2

[0036] like Figures 4 to 6 As shown, the base 1 includes two symmetrically arranged fixing blocks 12, which are detachably connected to each other. A chamber 24 is formed between the two fixing blocks 12, and the filter mechanism is disposed within the chamber 24. In this embodiment, the two fixing blocks 12 are connected by bolts, and the chamber 24 between the two fixing blocks 12 is a slot with openings at both ends to facilitate the entry and exit of dry ice particles.

[0037] Furthermore, as a preferred embodiment, the filter mechanism includes a semi-circular bottom plate 13, connecting plates 14 provided at both ends of the bottom plate 13, and a filter 5 provided on the bottom plate 13. The bottom plate 13 is fixed in the chamber 24 through the two connecting plates 14. The ice crushing mechanism is swingably provided on the upper side of the filter 5. Figure 6 As shown, an arc-shaped chute and fixed grooves are provided on the inner side wall of the fixed block 12, wherein the bottom plate 13 is provided in the chute, and the connecting plate 14 is fixed in the fixed groove. An opening for the dry ice particles to pass through is opened on the bottom plate 13, and the filter screen 5 covers the opening. The dry ice particles are filtered by the filter screen 5 and leave the base 1 through the opening.

[0038] Furthermore, as a preferred embodiment, the ice crushing mechanism includes a connecting shaft 7 and a swing arm 15 sleeved on the connecting shaft 7 , and an ice crushing blade 8 is provided at one end of the swing arm 15 away from the connecting shaft 7 .

[0039] Furthermore, as a preferred embodiment, the transmission mechanism includes a connecting rod 16, a connecting arm 17, a bearing 18, a support frame 19, a bushing 20, a support block 21 and a connecting block 22. The two ends of the connecting shaft 7 are rotatably connected to the two fixed blocks 12 through the two bearings 18, one end of the connecting rod 16 is connected to one end of the connecting shaft 7, and the other end of the connecting rod 16 is rotatably connected to one end of the connecting arm 17. A support frame 19 is provided on the driving mechanism. The two ends of the support frame 19 are rotatably connected to the two support blocks 21 through the two bushings 20. The two support blocks 21 are connected to the connecting block 22, and the connecting block 22 is fixed to one side of the base 1. In this embodiment, as Figure 6 As shown, the movement of cylinder 23 serves as the power source. Under the action of support frame 19, cylinder 23 can rotate relative to connecting block 22. When cylinder 23 drives connecting arm 17, connecting rod 16 rotates, connecting rod 16 drives connecting shaft 7 to rotate back and forth, and connecting shaft 7 drives swing arm 15 and ice crushing blade 8 to swing forward and backward. The forward and reverse swinging of ice crushing blade 8 crushes and refines dry ice particles, which are filtered through the screen and then leave base 1 through the opening. The dry ice crushing mechanism of this embodiment can be used as a dry ice particle refinement mechanism in dry ice cleaning equipment. It has a simple structure, high efficiency, and stable and reliable performance.
