[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Example 1:

[0021] like Figure 1-7As shown, the present invention provides a technical solution: a rapid crushing device for raw material processing based on robot manufacturing, including a crushing box 1 and a feeding hopper 2. The crushing box 1 is provided with a screening mechanism 3. The screening mechanism 3 includes a moving plate 301, a connecting plate 302, a filter screen 303, a supporting plate 304, and a motor 305. One end of the moving plate 301 is slidably connected to the inner wall of the crushing box 1, and the other end of the moving plate 301 is fixedly connected to one side of the connecting plate 302. The other side of the connecting plate 302 is fixedly connected to one end of the filter screen 303. One side of the supporting plate 304 is fixedly connected to the inner wall of the crushing box 1. A rotating rod 306 is fixedly installed at the output end of the motor 305. A fixing sleeve 307 is fixedly installed on the outer wall of the rotating rod 306. A stirring blade 308 is fixedly installed on the outer wall of the fixing sleeve 307. A guide plate 309 is fixedly installed on the inner wall of the crushing box 1. The inner wall of the crushing box 1 is provided with a moving groove. One end of the moving plate 301 is slidably connected to the inner wall of the moving groove. There are four moving plates 301, which are symmetrically distributed on the inner wall of the crushing box 1. There are two stirring blades 308, which are symmetrically distributed on the outer wall of the fixed sleeve 307. There are two connecting plates 302, which are symmetrically distributed at both ends of the filter screen 303. A spring is fixedly installed between the top of the connecting plate 302 and the bottom of the support plate 304. There are two springs, which are symmetrically distributed on the top of the connecting plate 302. This allows the filter screen 303 to reciprocate under the pressure of the stirring blade 308, thus achieving better filtration and screening. The top of the crushing box 1 is connected to the bottom of the feeding hopper 2. There are two feeding hoppers 2, which are symmetrically distributed on the top of the crushing box 1. A movable door is installed on the front of the crushing box 1. The operator pours the raw materials to be processed into the crushing box 1 through the feed hopper 2 located at the top of the crushing box 1. After the raw materials are crushed by the crushing mechanism 4, they are filtered and screened through the filter screen 303. At this time, the motor 305 is started to drive the rotating rod 306 to rotate. The rotation of the rotating rod 306 drives the fixed sleeve 307 to rotate. The rotation of the fixed sleeve 307 drives the stirring blade 308 to rotate. The rotation of the stirring blade 308 can squeeze the filter screen 303, causing the filter screen 303 to move and drive the connecting plate 302 to move. The movement of the connecting plate 302 causes the moving plate 301 to slide in the moving groove. The movement of the connecting plate 302 squeezes the spring, thereby enabling the filter screen 303 to reciprocate, preventing the raw materials from accumulating on the filter screen 303, and stirring the filtered raw materials to prevent clogging. The flow guide plate 309 is installed to better guide the flow. It enables better filtration and screening of pulverized raw materials, solving the problem that raw materials tend to accumulate on the filter screen during actual use, leading to filter screen blockage. It also avoids affecting the production efficiency of the rapid pulverizing device due to slow filtration speed and effectively prevents raw material accumulation and blockage. Example 2:

[0022] Based on Example 1, such as Figure 1-7 As shown, the present invention provides a technical solution: the stirring mechanism 4 includes a second motor 401, a second rotating rod 402, a connecting sleeve 403, a first crushing blade 404, and a first gear 405. The output end of the second motor 401 is fixedly connected to one end of the second rotating rod 402. The outer wall of the second rotating rod 402 is fixedly connected to the inner wall of the connecting sleeve 403. The outer wall of the connecting sleeve 403 is fixedly connected to one end of the first crushing blade 404. The outer wall of the second rotating rod 402 is fixedly connected to the inner wall of the first gear 405. The first gear 405 meshes with a second gear 406. A third rotating rod 407 is fixedly installed on the inner wall of the second gear 406. There are two connecting sleeves 403. The inner wall of one connecting sleeve 403 is fixedly connected to the outer wall of the second rotating rod 402, and the outer wall of the other connecting sleeve 403 is fixedly connected to the outer wall of the third rotating rod 407. There are several crushing blades 404. The crushing blades 404 are distributed on the outer walls of the two connecting sleeves 403 in sequence, so as to quickly crush the raw materials. When the raw materials enter the crushing chamber 1, the motor 401 starts and drives the rotating rod 402 to rotate. The rotating rod 402 drives the connecting sleeve 403 to rotate, which in turn drives the crushing blade 404 to rotate. As the rotating rod 402 rotates, it drives the gear 405 to rotate, which in turn drives the gear 406 to rotate, which in turn drives the rotating rod 407 to rotate, thus quickly crushing the raw materials. This technology enables rapid crushing of raw materials, thereby improving the crushing efficiency of the rapid crushing device, effectively enhancing its crushing effect, and making it more convenient for operators to use. Example 3:

[0023] Based on Example 1, such as Figure 1-7 As shown, the present invention provides a technical solution: an auxiliary mechanism 5 is provided on one side of the crushing box 1. The auxiliary mechanism 5 includes a bevel gear 1 501, a bevel gear 2 502, a rotating rod 4 504, and a crushing blade 2 505. The inner wall of the bevel gear 1 501 is fixedly connected to the outer wall of the rotating rod 1 306. One side of the bevel gear 1 501 meshes with one side of the bevel gear 2 502. The inner wall of the bevel gear 2 502 is fixedly connected to the outer wall of the rotating rod 4 504. The outer wall of the rotating rod 4 504 is fixedly connected to one end of the crushing blade 2 505. One side of the crushing box 1 is fixedly connected to one side of the auxiliary box 506. There are six crushing blades 505, which are symmetrically distributed on the outer wall of the rotating rod 504. The bottom of the auxiliary box 506 is provided with a discharge chute, which can filter and screen the raw materials for secondary crushing, and crush the raw materials more thoroughly. After the raw materials are filtered and screened, they enter the auxiliary box 506. As the rotating rod 306 rotates, it drives the bevel gear 501 to rotate, which in turn drives the bevel gear 502 to rotate, which in turn drives the rotating rod 504 to rotate, which in turn drives the crushing blade 505 to rotate, thus enabling the raw materials to be crushed a second time, making the crushing of the raw materials more thorough. It enables secondary crushing of raw materials that have been filtered and screened, thereby effectively reducing the production of substandard raw materials and enabling more thorough crushing of raw materials. Example 4:

[0024] Based on Example 1, such as Figure 1-7 As shown, the present invention provides a technical solution: a support mechanism 6 is provided below the crushing box 1. The support mechanism 6 includes a support rod 601, a buffer plate 602, a buffer box 603, a support plate 604, and a reinforcing plate 605. One end of the support rod 601 is fixedly connected to one side of the crushing box 1, and the other end of the support rod 601 is fixedly connected to the top of the buffer plate 602. Both ends of the buffer plate 602 are slidably connected to the inner wall of the buffer box 603. The bottom of the buffer box 603 is fixedly connected to the top of the support plate 604. The outer wall of the support rod 601 is fixedly connected to the inner wall of the reinforcing plate 605. A damper 606 is fixedly installed at the bottom of the reinforcing plate 605. The support rods 601 are L-shaped, and there are four support rods 601. Two support rods 601 are fixedly connected to one side of the crushing box 1 at one end, and two support rods 601 are fixedly connected to one side of the auxiliary box 506 at one end. Two springs are fixedly installed between the bottom of the buffer plate 602 and the inner wall of the buffer box 603. The springs 602 are symmetrically distributed at the bottom of the buffer plate 602, so as to reduce vibration and buffer when vibration occurs during the operation of the rapid crushing device, and better protect it. When the rapid crushing device vibrates during operation, the support rod 601 moves, causing the buffer plate 602 to slide in the buffer box 603. The sliding of the buffer plate 602 compresses the second spring. As the support rod 601 moves, the reinforcing plate 605 moves, and the reinforcing plate 605 compresses the damper 606, thereby reducing vibration and buffering, reducing the noise generated during operation, and providing better support. It enables vibration damping and buffering when vibration occurs during the operation of the rapid pulverizer, thereby better protecting the rapid pulverizer and reducing the noise generated during its operation.
