[0026] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figure 1-Figure 4 As shown, the silicon material crushing device provided in the present application includes an exhaust pipe 10 and two silicon material crushing units X.

[0028] The structures of the two silicon material crushing units X are basically the same. The two silicon material crushing units X each include a crushing table 20 , a crushing table cover 30 and an exhaust grille 50 .

[0029] The crushing table cover 30 includes a back plate 31. The air extraction grille 50 is fixed to the back plate 31, and the fixing method is not limited, and it can be assembled and fixed or set in one piece.

[0030] An air extraction chamber cover 40 is provided between the back plates 31 of the two silicon material crushing units X. The back plates 31 of the two silicon material crushing units X and the air extraction chamber cover 40 enclose an air extraction chamber. The air extraction pipe 10 is connected to the air extraction chamber.

[0031] The silicon material crushing device provided by the present application has two silicon material crushing units X, each of which has a crushing table 20, so that the whole has two crushing tables 20, and the two silicon material crushing units X are integrated together through the exhaust chamber cover 40. In the past, each silicon material crushing device only had one crushing table, and each silicon material crushing device was arranged separately. In comparison, the silicon material crushing device provided by the present application has a higher degree of integration and occupies a smaller area than the two silicon material crushing devices arranged separately in the past.

[0032] Furthermore, the exhaust pipe 10 of the silicon material crushing device provided in the present application is simultaneously connected to the exhaust grilles 50 of the two silicon material crushing units X through the exhaust chamber, so that the two crushing tables 20 correspond to the same exhaust pipe 10. In the past, each crushing table corresponded to a separate exhaust pipe. In comparison, the number of exhaust pipes 10 of the silicon material crushing device provided in the present application is reduced, and the purchase and assembly costs of the exhaust pipes 10 are reduced, so the configuration cost is reduced. In addition, under the same exhaust pressure, since the number of exhaust pipes 10 is reduced, the wind pressure in each exhaust pipe 10 increases, and therefore, the suction effect is improved.

[0033] In short, the silicon material crushing device provided in the present application occupies a small area, has a low configuration cost, and has a good suction effect.

[0034] Specifically, Figure 2 As shown, the back plates 31 of the two silicon material crushing units X can be tilted so that the width of the air extraction chamber increases gradually from bottom to top. This is more conducive to improving the suction effect.

[0035] Specifically, Figure 1 As shown, the crushing table cover 30 also includes a baffle 32, a side plate 33 and a top cover 34. The baffle 32 is opposite to the back plate 31, and the left and right sides of the baffle 32 and the back plate 31 are each connected to a side plate 33, and the top cover 34 is connected to the top of the back plate 31 and the side plate 33. There is an operation port between the baffle 32 and the top cover 34, and the operator crushes the silicon material on the crushing table 20 through the operation port.

[0036] Specifically, the plate surface of the crushing table cover 30 facing the crushing table 20 and the table surface of the crushing table 20 are covered with crystal cloth (not shown in the figure) to prevent the plate surface or table surface material debris caused by the crushing process from mixing into the silicon material. The plate surface of the crushing table cover 30 facing the crushing table 20 includes the front surface of the back plate 31, the right side plate surface of the left side vertical plate 33, and the left side plate surface of the right side vertical plate 33.

[0037] Specifically, Figure 1 As shown, the air extraction chamber cover 40 includes a top panel 42, a side panel 41 and a bottom panel (not visible in the figure), and the top panel 42 and the bottom panel are each connected to a side panel 41 on the left and right sides. The air extraction pipe 10 can be connected to the top panel 42 of the air extraction chamber cover 40, as shown in the figure. Alternatively, the air extraction pipe 10 can also be connected to the side panel 41 of the air extraction chamber cover 40.

[0038] Specifically, Figure 1 As shown, the suction chamber cover 40 is provided with a cleaning port, and the cleaning port is preferably provided on the side panel 41 of the suction chamber cover 40. A door panel 60 for opening and closing the cleaning port is assembled on the suction chamber cover 40. The assembly method of the door panel 60 and the suction chamber cover 40 is not limited. For example, a slot can be provided on the suction chamber cover 40, and the door panel 60 is inserted therein, and the door panel 60 slides along the slot to achieve opening and closing. For another example, a connecting hole can be provided on the suction chamber cover 40, and the door panel 60 is pivotally connected to the connecting hole, and the door panel 60 rotates around the pivot axis to achieve opening and closing. In order to facilitate opening and closing of the door panel 60, a handle can be provided on the outside of the door panel 60.

[0039] When there are debris and silicon powder accumulation on the back side of the exhaust grille 50, open the door panel 60, extend the cleaning device through the cleaning port into the exhaust cavity to clean the back side of the exhaust grille 50, so that the back side of the exhaust grille 50 can be easily cleaned. The cleaning device can be a dust collection device.

[0040] Specifically, Figure 1 As shown, the two silicon material crushing units X may further include a discharge ramp 70 and a packaging table (not shown in the figure) located below the discharge ramp 70. The discharge ramp 70 is arranged on the side of the crushing table 20 opposite to the back plate 31. The high end of the slope surface of the discharge ramp 70 (indicated by B in the figure) is flush with the table surface of the crushing table 20.

[0041] When discharging, a packaging bag is placed at the lower end of the slope of the discharging ramp 70, and the crushed materials of appropriate size on the table of the crushing table 20 first go up to the upper end of the slope of the discharging ramp 70, then slide along the slope to the lower end of the slope of the discharging ramp 70, and then slide into the packaging bag, and then the packaging bag is sealed on the packaging table.

[0042] Specifically, Figure 1 As shown, discharge baffles 80 are provided on both sides (left and right sides in the figure) of the slope of the discharge ramp 70. The top side of the discharge baffle 80 is provided with an inclined surface (indicated by A in the figure), and the lower end of the inclined surface is flush with the lower end of the slope of the discharge ramp 70. With this design, when discharging, the packaging bag can be sleeved on the lower end of the discharge ramp 70, so that the silicon material is not easy to spill out of the packaging bag. If the lower end of the inclined surface is higher than the lower end of the slope of the discharge ramp 70 by a large distance, the packaging bag will not be able to be sleeved on the lower end of the discharge ramp 70 due to the size limitation of the packaging bag opening.

[0043] Specifically, Figure 3 As shown, the two silicon material crushing units X may further include an exhaust hole plate 90. The exhaust hole plate 90 is fixed to the back plate 31 and is located above the exhaust grille 50. The exhaust hole plate 90 is provided with a plurality of exhaust holes, and each exhaust hole may be arranged in a matrix. With this design, the raised silicon powder can be quickly sucked away through the exhaust hole plate 90, reducing the harm to the human body.

[0044] Specifically, Figure 1 As shown, the silicon material crushing device may further include an air valve 100. The air valve 100 is installed on the exhaust pipe 10 and is used to adjust the opening of the exhaust pipe 10. When the silicon material crushing device is not currently crushing silicon materials, the exhaust pipe 10 of the silicon material crushing device can be closed by the air valve 100 to avoid the exhaust pipe 10 of the silicon material crushing device from wasting the exhaust pressure of the exhaust machine.

[0045] Specifically, Figure 1 As shown, the crushing table 20 includes a main board 21 and a sieve plate 22, and the top surface of the sieve plate 22 and the top surface of the main board 21 form the table surface of the crushing table 20. The sieve plate 22 is used to screen out silicon materials with a particle size smaller than a preset value (for example, 10 mm). Both silicon material crushing units X include a material receiving box 120, which is located below the sieve plate 22 to receive silicon materials with a particle size smaller than the preset value screened by the sieve plate 22.

[0046] Specifically, Figure 1 As shown, the silicon material crushing device may further include a support frame 110, and the support frame 110 may be formed by splicing square tubes. The exhaust chamber cover 40 and the crushing table 20 and the crushing table cover 30 of the two silicon material crushing units X are all supported on the support frame 110. The material receiving box 120 of the two silicon material crushing units X can be pulled out and installed on the support frame 110. This design allows the two silicon material crushing units X to share a support frame 110. Compared with the previous silicon material crushing device with a single support frame, the material used for the support frame is reduced, which is more conducive to reducing the configuration cost.

[0047] Specifically, Figure 1 As shown, the two silicon material crushing units X each include an under-table niche 130, which is located below the crushing table 20 and fixed to the support frame 110. The under-table niche 130 can accommodate the tooling fixtures used for crushing and packaging operations and labor protection supplies for operators.

[0048] Specifically, the silicon material crushing unit X and the vacuum chamber cover 40 can be made of polypropylene (PP) material. The support frame 110 can be made of metal material, and the surface of the metal material is wrapped with a polypropylene plate.

[0049] The above specific examples are used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
