For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0026] The utility model provides a technical solution:

[0027] Example 1

[0028] Combine Figures 1 to 4 A primary crushing device for producing metallic silicon powder includes a main shell 3, a feed port 31 fixedly connected to the top of the main shell 3, a support leg 4 fixedly connected to the bottom of the main shell 3, a base 5 fixedly connected to the bottom of the support leg 4, a crushing mechanism 1 is provided on the front side of the main shell 3, and a driving mechanism 2 is provided on the top of the base 5.

[0029] The crushing mechanism 1 includes a crushing assembly 11 , a reversing assembly 12 and a supporting assembly 13 . The crushing assembly 11 is arranged in the main housing 3 , the reversing assembly 12 is arranged in front of the crushing assembly 11 , and the supporting assembly 13 is arranged in front of the reversing assembly 12 .

[0030] The crushing assembly 11 includes a crushing roller 1101, which is arranged in the main shell 3 below the feed port 31. The inner ring of the crushing roller 1101 is fixedly connected to the rotating shaft 1102, and the rotating shaft 1102 is rotatably connected to the front and rear sides of the main shell 3. The reversing assembly 12 includes a forward gear 1201, which is fixedly connected to the front side of the left rotating shaft 1102. The bottom right side of the forward gear 1201 is engaged with a transmission gear 1202, the top of the transmission gear 1 1202 is engaged with a transmission gear 2 1203, and the right side of the transmission gear 2 1203 is engaged with a reversing gear 1204. The supporting assembly 13 includes a clamping rod 1301, which is rotatably connected to the transmission gear 1 1202 and the inner ring of the transmission gear 2 1203. The clamping rod 1301 is fixedly connected to the front side of the main shell 3, and the front side of the clamping rod 1301 is fixedly connected to a connecting plate 1302.

[0031] Furthermore: the crushing rollers 1101 on the left and right sides are driven by the meshing of the forward gear 1201, the transmission gear 1 1202, the transmission gear 2 1203 and the reverse gear 1204, so that the crushing rollers 1101 on the left and right sides can always maintain synchronous reverse rotation, ensuring that the crushing rollers 1101 on the left and right sides rotate to perform preliminary crushing processing on the materials entering the main shell 3. At the same time, the transmission gear 1 1202 and the transmission gear 2 1203 are located between the forward gear 1201 and the reverse gear 1204 on the left and right sides for transmission meshing, so that the forward gear 1201 and the reverse gear 1204 do not need to have an excessively large diameter, reducing the size and weight of the forward gear 1201 and the reverse gear 1204, making it convenient for the staff to disassemble and maintain them later.

[0032] Example 2

[0033] See Figures 1 to 5 , and on the basis of Example 1, it is further obtained that the driving mechanism 2 includes a driving component 21, a transmission component 22 and a reinforcement component 23, the driving component 21 is arranged on the top of the base 5, the transmission component 22 is arranged on the front side of the driving component 21, and the reinforcement component 23 is arranged on the outer ring of the driving component 21.

[0034] The driving assembly 21 includes a driving motor 2101, which is fixedly connected to the top of the base 5. The front side of the driving motor 2101 is fixedly connected to a rotating shaft 2102. The transmission assembly 22 includes a transmission wheel 1 2201, which is fixedly connected to the front side of the rotating shaft 2102. The outer ring of the transmission wheel 1 2201 is connected to a transmission belt 2202. The top of the inner ring of the transmission belt 2202 is connected to a transmission wheel 2 2203. The transmission wheel 2 2203 is fixedly connected to the front side of the forward gear 1201. The reinforcement assembly 23 includes a supporting drum 2301, which is rotatably connected to the outer ring of the rotating shaft 2102. The bottom of the supporting drum 2301 is fixedly connected to a fixing rod 2302. The fixing rod 2302 is fixedly connected to the top of the base 5. The left side of the supporting drum 2301 is fixedly connected to a reinforcement arm 2303. The reinforcement arm 2303 is fixedly connected to the inner side of the base 5.

[0035] Furthermore: the staff only needs to start the drive motor 2101 to drive the forward gear 1201 to rotate, and complete the synchronous rotation of the left and right crushing rollers 1101. The operation is simple and convenient for the staff to use. The support drum 2301 is fixed to the top of the base 5 through the fixing rod 2302 and the reinforcement arm 2303 to support the rotating shaft 2102, which increases the stability of the rotating shaft 2102 during rotation, and improves the stability of the rotation of the left and right crushing rollers 1101 when the device is in use.

[0036] During actual operation, when the device is used, the staff first starts the drive motor 2101. The drive motor 2101 starts to drive the transmission wheel 1 2201 to rotate through the rotating shaft 2102. The transmission wheel 1 2201 rotates through the transmission belt 2202 to drive the transmission wheel 2 2203 to rotate. The transmission wheel 2 2203 rotates to drive the forward gear 1201 to rotate. The forward gear 1201 rotates through the rotating shaft 1102 on the left to drive the crushing roller 1101 on the left to rotate. At the same time, the forward gear 1201 rotates through the transmission gear 1 1202 to drive the transmission gear The second gear 1203 rotates, and the rotation of the transmission gear 1203 drives the reversing gear 1204 to rotate. The reversing gear 1204 rotates through the right rotating shaft 1102 to drive the crushing roller 1101 on the right to rotate. At this time, the rotation speeds of the crushing rollers 1101 on the left and right sides are synchronized and the rotation directions are opposite. Then, the material to be crushed can be poured into the feed port 31, so that the crushing rollers 1101 on the left and right sides rotate to complete the crushing. The crushed material is then discharged to the right through the bevel at the bottom of the main shell 3. At this time, the preliminary crushing process of the material is completed.

[0037] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.
