Silicon carbide has high hardness, high wear resistance, high thermal conductivity, high chemical stability, and excellent electrical properties, making it an indispensable key material for modern industry. In the production process of silicon carbide, the initial synthesized silicon carbide raw materials are often in the form of blocks or large particles, which is far from the strict standards of various industries for silicon carbide particles. Therefore, it needs to be crushed and screened.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1, referring to Figures 1 - 8 as shown: The present invention provides a silicon carbide particle shaping and screening integrated machine, including a screening mechanism 1, and a crushing mechanism 2 is arranged on the top of the screening mechanism 1; The crushing mechanism 2 includes a crushing box 21. An inner wall of the crushing box 21 is fixedly provided with a feed box 23. Two insertion grooves 231 are formed in an inner wall of the feed box 23. Movable plates 232 are movably inserted into inner walls of the two insertion grooves 231. One side of an outer wall of the feed box 23 is fixedly provided with two expansion links 233. Expansion ends of the two expansion links 233 are fixedly connected to one side of an outer wall of the movable plate 232. A mounting frame 24 is fixedly arranged on the top of the feed box 23. A sixth motor 241 is fixedly arranged on the top of the mounting frame 24. An output end of the sixth motor 241 is fixedly sleeved with a first bevel gear 242.

A high-frequency vibrator 261 is fixedly arranged on the top of the pressure plate 26.

[0022] In this embodiment, when the silicon carbide needs to be crushed, the preliminarily synthesized silicon carbide is first conveyed into the feeding box 23. Under the action of the telescopic rod 233, the movable plate 232 is closed to prevent the leakage of silicon carbide particles. Subsequently, under the action of the sixth motor 241, the first bevel gear 242 is driven to rotate. At the same time, under the action of the second bevel gear 251, the lead screw 25 is driven to rotate. Through the rotation of the lead screw 25 and the cooperation of the limiting rod on the other side of the mounting frame 24, the pressing plate 26 can be driven to move downward to a suitable position, so that the bottom of the pressing plate 26 is in full contact with the silicon carbide particles inside the feeding box 23. Subsequently, under the action of the high-frequency vibrator 261, a high-frequency vibration impact force is generated. After transmission, small cracks are formed inside the silicon carbide particles. During this process, under the action of the sixth motor 241, the first bevel gear 242, the second bevel gear 251, and the lead screw 25, the pressing plate 26 can be continuously driven to move downward, so as to extrude the silicon carbide particles. When the silicon carbide particles inside the feeding box 23 are pretreated, again under the action of the sixth motor 241, the first bevel gear 242, the second bevel gear 251, and the lead screw 25, the pressing plate 26 is driven to move upward to a suitable position. Subsequently, under the action of the telescopic rod 233, the movable plate 232 is driven to move to a suitable position inside the insertion groove 231, so as to convey the pretreated silicon carbide particles into the next mechanism for processing. Through the above method, the silicon carbide particles can be made more relaxed and more sufficient in the subsequent crushing process.

[0023] Embodiment 2, according to Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, a top cover 211 is fixedly installed on the top of the crushing box 21.

A fifth motor 221 is fixedly installed on one side of the outer wall of the crushing box 21, and the output end of the fifth motor 221 is fixedly connected to the outer surface wall of the bidirectional lead screw 22.

[0024] In this embodiment, when the silicon carbide particles enter the interior of the crushing box 21 after pretreatment, under the action of the fourth motor 217, the second gear 218 is driven to rotate. At the same time, under the action of the first gear 216, the crushing roller 215 is driven to rotate. The entering silicon carbide particles can be crushed by the rotation of the two crushing rollers 215. During the crushing process, under the action of the fifth motor 221, the bidirectional lead screw 22 is driven to rotate, thereby driving the slider 214 to move inside the embedding groove 213 and driving the crushing roller 215 to move, so as to adjust the distance between the crushing rollers 215, enabling it to crush and process silicon carbide particles of different sizes, greatly improving the practicability of the equipment. Moreover, during the crushing process of the silicon carbide particles, under the action of the top cover 211 and the protective shell 212, it is possible to prevent the silicon carbide particles from splashing out during crushing, thus protecting the surrounding staff and avoiding waste of the silicon carbide particles.

A connecting rod 118 is movably sleeved on the outer wall of the toothed row 115, and the inner wall of the connecting rod 118 is movably connected to the outer wall of the eccentric wheel 113. On one side of the outer wall of the housing 11, a transmission wheel 116 is fixedly installed through a fixing frame, and the outer wall of the transmission wheel 116 meshes with the outer wall of the toothed row 115. Two movable grooves 117 are formed on the outer wall of the housing 11. A screening box 12 is movably embedded between the inner walls of the two movable grooves 117. One side of the outer wall of the screening box 12 meshes with the outer wall of the transmission wheel 116. Two installation grooves 121 are formed on the inner wall of the screening box 12. Two buffer springs 123 are fixedly installed on the inner walls of the two installation grooves 121. A screening plate 122 is arranged between the inner walls of the two installation grooves 121, and the bottom of the screening plate 122 is fixedly connected to the top of the buffer spring 123. A damper 124 is arranged on the inner wall of each of the four buffer springs 123. A guide plate 125 is fixedly installed on the inner wall of the screening box 12. Two fixing grooves 126 are formed on the outer wall of the screening box 12. A discharge box 127 is fixedly inserted into the inner walls of the two fixing grooves 126. A collection box 13 is fixedly installed at the bottom of the inner wall of the housing 11, and the inner wall of the collection box 13 is fixedly communicated with the outer wall of one of the discharge boxes 127. A first conveying pipe 14 is fixedly installed at the bottom of the inner wall of the housing 11, and the inner wall of the first conveying pipe 14 is fixedly communicated with the outer wall of the other discharge box 127. A first spiral blade 141 is arranged on the inner wall of the first conveying pipe 14. A second motor 142 is fixedly installed at the bottom of the inner wall of the housing 11, and the output end of the second motor 142 is fixedly connected to the outer wall of the first spiral blade 141.

The outer wall of the connecting pipe 15 is fixedly inserted into the inside of the crushing box 21.

[0026] In this embodiment, when the silicon carbide particles are broken and enter the inside of the screening box 12, after being broken, the silicon carbide particles fall onto the top of the screening plate 122 under the action of gravity. During this process, under the action of the buffer spring 123 and the damper 124, the force generated when the silicon carbide particles fall can be buffered, preventing the screening plate 122 from being damaged after long-term use and greatly extending the service life of the screening plate 122. When the silicon carbide particles reach the top of the screening plate 122, under the action of the first motor 112, the eccentric wheel 113 is driven to rotate. At the same time, under the action of the connecting rod 118 and the limit block 114, the tooth row 115 can be driven to move reciprocally. And with the cooperation of the transmission wheel 116, the screening box 12 can be driven to move reciprocally inside the movable groove 117. Meanwhile, under the action of the screening plate 122, the silicon carbide particles are screened. The fine silicon carbide particles after screening will fall onto the top of the guide plate 125 and enter the collection box 13 through the discharge box 127 (the discharge box 127 is made of rubber and has good stretchability and deformation ability) for collection and storage for subsequent processing and use. Among them, the larger silicon carbide particles remaining on the top of the screening plate 122 will enter the first conveying pipe 14 through the discharge box 127. Then, under the action of the second motor 142, the first spiral blade 141 is driven to rotate, so that the silicon carbide particles inside the first conveying pipe 14 move forward under the force of rotational extrusion to the inside of the second conveying pipe 143. Subsequently, under the action of the third motor 145 and the second spiral blade 144, the silicon carbide particles inside the second conveying pipe 143 continue to move into the connecting pipe 15. Due to the angle of the connecting pipe 15, the silicon carbide particles inside it will enter the crushing device again for crushing treatment, greatly improving the processing quality of the silicon carbide and making it more convenient for subsequent use.

[0027] The working principle of the whole mechanism is as follows: When the preliminarily synthesized silicon carbide particles need to be crushed and processed, first, the preliminarily synthesized silicon carbide is conveyed into the feeding box 23. Under the action of the telescopic rod 233, the movable plate 232 is closed to prevent the leakage of silicon carbide particles. Subsequently, under the action of the sixth motor 241, the first bevel gear 242 is driven to rotate. At the same time, under the action of the second bevel gear 251, the lead screw 25 is driven to rotate. Through the rotation of the lead screw 25 and the cooperation of the limiting rod on the other side of the mounting frame 24, the pressing plate 26 can be driven to move downward to a suitable position, so that the bottom of the pressing plate 26 is in full contact with the silicon carbide particles inside the feeding box 23. Subsequently, under the action of the high-frequency vibrator 261, high-frequency vibration impact force is generated. After transmission, fine cracks inside the silicon carbide particles are formed. During this process, under the action of the sixth motor 241, the first bevel gear 242, the second bevel gear 251, and the lead screw 25, the pressing plate 26 can be continuously driven to move downward, so as to extrude the silicon carbide particles. When the silicon carbide particles inside the feeding box 23 are pretreated, again under the action of the sixth motor 241, the first bevel gear 242, the second bevel gear 251, and the lead screw 25, the pressing plate 26 is driven to move upward to a suitable position. Subsequently, under the action of the telescopic rod 233, the movable plate 232 is driven to move to a suitable position inside the insertion slot 231, so as to convey the pretreated silicon carbide particles into the crushing box 21. When the silicon carbide particles enter the crushing box 21 after pretreatment, under the action of the fourth motor 217, the second gear 218 is driven to rotate. At the same time, under the action of the first gear 216, the crushing roller 215 is driven to rotate. Through the rotation of the two crushing rollers 215, the entering silicon carbide particles can be crushed. During the crushing process, under the action of the fifth motor 221, the bidirectional lead screw 22 is driven to rotate, thereby driving the slider 214 to move inside the embedding slot 213 and driving the crushing roller 215 to move, so as to adjust the distance between the crushing rollers 215, enabling it to crush and process silicon carbide particles of different sizes, greatly improving the practicability of the equipment. And during the crushing of the silicon carbide particles, under the action of the top cover 211 and the protective shell 212, it can prevent the silicon carbide particles from splashing out during crushing, thus playing a protective role for the surrounding workers. When the silicon carbide particles are crushed and enter the screening box 12, under the action of gravity, the crushed silicon carbide particles fall onto the top of the screening plate 122. During this process, under the action of the buffer spring 123 and the damper 124, the force generated when the silicon carbide particles fall can be buffered, preventing the screening plate 122 from being damaged after long-term use and greatly extending the service life of the screening plate 122. When the silicon carbide particles reach the top of the screening plate 122, under the action of the first motor 112, the eccentric wheel 113 is driven to rotate. At the same time, under the action of the connecting rod 118 and the limiting block 114,It can drive the tooth row 115 to reciprocate, and with the cooperation of the transmission wheel 116, it can drive the screening box 12 to reciprocate inside the movable slot 117. At the same time, under the action of the screening plate 122, the silicon carbide particles are screened. The fine silicon carbide particles after screening will fall onto the top of the guide plate 125 and enter the collection box 13 through the discharge box 127 (the discharge box 127 is made of rubber and has good stretchability and deformation ability) for collection and storage for subsequent processing and use. Among them, the larger silicon carbide particles remaining on the top of the screening plate 122 will enter the first conveying pipe 14 through the discharge box 127. Then, under the action of the second motor 142, the first spiral blade 141 is driven to rotate, so that the silicon carbide particles inside the first conveying pipe 14 are forced to move forward by the rotating extrusion force to the inside of the second conveying pipe 143. Subsequently, under the action of the third motor 145 and the second spiral blade 144, the silicon carbide particles inside the second conveying pipe 143 continue to move into the connecting pipe 15. Due to the angle of the connecting pipe 15, the silicon carbide particles inside it will enter the crushing mechanism 2 again for crushing treatment, improving the processing quality of silicon carbide and reducing the labor intensity of the staff.
