[0027] See also Figure 1 , Figure 1 The schematic diagram of the structure of the circuit board crushing device in one embodiment of the utility model comprises a box 100, a crushing assembly 200 and a filter assembly 300. The box 100 has a crushing chamber 110 and a discharge chamber 120. The crushing chamber 110 is higher than the discharge chamber 120, and the box 100 is provided with a disassembly opening 130. The crushing assembly 200 comprises a reamer 210 built into the crushing chamber 110, and the reamer 210 is used to crush the material in the crushing chamber 110. The filter assembly 300 comprises a screen 310 and a support frame 320. The screen 310 is detachably mounted on the support frame 320. The support frame 320 is movably arranged on the box 100, and its moving track has at least a first position in which the screen 310 separates the crushing chamber 110 and the discharge chamber 120, and a second position in which the screen 310 is separated from the box 100 through the disassembly opening 130.

[0028] In this embodiment, the support frame 320 is adjusted to the first position so that the screen 310 separates the crushing chamber 110 and the discharge chamber 120. The material to be crushed is put into the crushing chamber 110, and the reamer 210 is used to crush the material in the crushing chamber 110. The material with smaller particles will pass through the screen 310 and enter the discharge chamber 120, while the material with larger particles will remain in the crushing chamber 110 and continue to be crushed. When it is necessary to clean and maintain the screen 310, the support frame 320 can be adjusted to the second position so that the screen 310 can be separated from the box 100 through the disassembly port 130. With the above-mentioned circuit board crushing device, the screen 310 can be easily separated from the box 100 by adjusting the position of the support frame 320, so that the operator can clean and maintain the screen 310 from the outside of the box 100, thereby improving the working efficiency of cleaning and maintaining the screen 310.

[0029] In some embodiments, one end of the support frame 320 is pivotally connected to the box body 100 , so that the support frame 320 can be flipped relative to the box body 100 .

[0030] In this embodiment, since one end of the support frame 320 is pivotally connected to the box body 100, the support frame 320 can rotate along the pivot, and then the support frame 320 can be switched between the first position and the second position. However, it should be emphasized that the support frame 320 is not the only embodiment to be pivotally mounted on the box body 100. The support frame 320 can also be slidably set on the box body 100. As long as the support frame 320 can be switched between the first position and the second position, the embodiment is feasible.

[0031] Based on the above embodiments, in some of the embodiments, the filter assembly 300 also includes a limit member 330, which is transmission-connected to the support frame 320, and the limit member 330 has a positioning state for limiting the rotation of the support frame 320 relative to the box body 100, and an adjustment state for allowing the support frame 320 to rotate relative to the box body 100.

[0032] In this embodiment, when the support frame 320 is in the first position, the position limiting member 330 is adjusted to the positioning state, thereby fixing the positions of the support frame 320 and the screen 310, and preventing the screen 310 from being separated from the first position during the process of crushing the circuit board. When the screen 310 needs to be repaired, the position limiting member 330 can be switched to the adjustment state, so that the position of the support frame 320 can be adjusted, and the support frame 320 can be switched from the first position to the second position.

[0033] In some embodiments, the box body 100 is provided with a matching hole 140 , the support frame 320 is provided with a screw hole 321 , and the stopper 330 includes a bolt 331 , which passes through the matching hole 140 and is screwed into the screw hole 321 .

[0034] In this embodiment, the bolt 331 is passed through the matching hole 140 and screwed into the screw hole 321, and the bolt 331 can be used to limit the movement of the support frame 320 relative to the box body 100. It can be understood that the support frame 320 only needs to be positioned in the first position.

[0035] In some embodiments, the inner wall of the box body 100 has a clamping portion 150 , and when the support frame 320 is in the first position, the support frame 320 presses against the clamping portion 150 .

[0036] In this embodiment, the clamping portion 150 is used to limit the support frame 320 so that the support frame 320 can be accurately located in the first position.

[0037] In some embodiments, the support frame 320 further includes a handle 322 , and the support frame 320 can be rotated by dragging the handle 322 .

[0038] In this embodiment, the operator can drive the support frame 320 to rotate by holding the handle 322 .

[0039] In some embodiments, the support frame 320 defines a mounting slot 323 , and the screen 310 is embedded in the mounting slot 323 .

[0040] In this embodiment, the screen 310 is placed in the mounting groove 323 so that the screen 310 can be stably mounted on the support frame 320 .

[0041] In some embodiments, the housing 100 further includes an inspection door 160 , which is openably and closably mounted on the disassembly opening 130 .

[0042] In this embodiment, when the support frame 320 is in the first position, the inspection door 160 can be closed, thereby sealing the disassembly opening 130, so as to facilitate the crushing of the circuit board. When the screen 310 needs to be maintained, the inspection door 160 can be opened, thereby opening the disassembly opening 130, so that the screen 310 can be separated from the box 100 through the disassembly opening 130.

[0043] In some of the embodiments, the box body 100 is provided with an inlet 170 connected to the crushing chamber 110 , and a outlet 180 connected to the discharge chamber 120 .

[0044] In this embodiment, the crushed material passes through the screen 310 and enters the discharge chamber 120 , and then the material can be discharged through the discharge port 180 .

[0045] In some of the embodiments, the screen 310 is in an arc shape that fits the reamer 210. Since the screen 310 fits the reamer 210, the material that cannot pass through the screen 310 can fully contact the reamer 210, thereby obtaining a more ideal crushing effect.

[0046] In order to better understand the present invention, the following Figure 1 to Figure 2 The technical solution of the utility model is described in detail:

[0047] The support frame 320 is adjusted to the first position, and the support frame 320 is limited to rotate relative to the box 100 by the limiter 330, so that the support frame 320 is stably in the first position. At this time, the screen 310 separates the crushing chamber 110 and the discharge chamber 120. The material to be crushed is put into the crushing chamber 110, and the reamer 210 is used to crush the material in the crushing chamber 110. The material with smaller particles will pass through the screen 310 and enter the discharge chamber 120, while the material with larger particles will remain in the crushing chamber 110 and continue to be crushed. Because the screen 310 fits the arc shape of the reamer 210, the material that cannot pass through the screen 310 can fully contact the reamer 210, thereby obtaining a more ideal crushing effect. When the screen 310 needs to be cleaned and maintained, the support frame 320 can be adjusted to the second position so that the screen 310 can be separated from the box 100 through the disassembly port 130. By using the circuit board crushing device, the screen 310 can be easily separated from the box 100 by adjusting the position of the support frame 320, so that the operator can clean and maintain the screen 310 from the outside of the box 100, thereby improving the working efficiency of cleaning and maintaining the screen 310.

[0048] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
