[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1 - Figure 4As shown, the utility model provides a crushed material screening and blowing device, including a support frame 1, a screening screen 4 is installed inside the support frame 1, a mobile blowing assembly 2 is arranged on the surface of the support frame 1, and the mobile blowing assembly 2 includes a screw groove 201, two groups of screw grooves 201 are respectively opened on the two side surfaces of the support frame 1, a first one-way screw 202 is inserted into the interior of one group of screw grooves 201, one end of the first one-way screw 202 is connected to a bearing 203, the other end of the first one-way screw 202 is connected to a first pulley 204, one side of the first pulley 204 is connected to the output end of a motor 205, a transmission belt 206 is arranged on the surface of the first pulley 204, one side of the transmission belt 206 is connected to a second pulley 207, and the other group of screw grooves 2 01 is plugged into the inside of the second one-way screw 208, the surfaces of the first one-way screw 202 and the second one-way screw 208 are connected with a purge rack 209, threaded holes 210 are provided at the bottom of both sides of the purge rack 209, an air intake pipe 211 is plugged into the top of the purge rack 209, and a high-pressure nozzle 212 is connected to the bottom of the air intake pipe 211, a fixed connection is formed between the output end of the motor 205 and the first pulley 204, a rotational connection is formed between the first one-way screw 202 and the bearing 203, a threaded connection is formed between the bottom of both sides of the purge rack 209 and the first one-way screw 202 and the second one-way screw 208 through the threaded holes 210, and the first pulley 204 is rotationally connected to the second pulley 207 through the transmission belt 206.

[0025] The effect achieved by the entire embodiment 1 is that after the screening mesh 4 screens the crushed materials, a lot of dust and impurities often remain on its surface. In order to clean these residues, the forward rotation function of the motor 205 can be turned on first, so that the motor 205 drives the first pulley 204 to rotate forward through the output end, and then drives the second pulley 207 to rotate through the transmission belt 206, so that the first one-way screw 202 and the second one-way screw 208 can rotate at the same time. At the same time, the purge frame 209 will also rotate with the threaded holes 210 on both sides of the bottom, and then drive the purge frame 209 to rotate in the screening process through the threaded rotation. The surface of the sieve 4 moves, and at this time the external air pump can be turned on, so that the high-pressure air pump can supply air to the high-pressure nozzle 212 through the air inlet pipe 211, so that the high-pressure nozzle 212 sprays high-pressure gas to purge the dust and impurities on the surface of the sub-sieve 4. The purge frame 209 will also purge the sub-sieve 4 while moving on the surface of the sub-sieve 4. After completing one cleaning, the reverse rotation function of the motor 205 can be turned on, so that the purge frame 209 can be reset to the initial position through threaded rotation, and prepare for the next purge and cleaning work. This automated cleaning method effectively avoids the time-consuming and labor-intensive problems of manual cleaning, and significantly improves the cleaning efficiency of the sub-sieve 4.

[0026] Embodiment 2, as Figure 1 , Figure 2and Figure 4 As shown, the outer surface of the support frame 1 is connected to a storage component 3, and the storage component 3 includes a storage box 301. The inner walls on both sides of the storage box 301 are embedded with magnetic blocks 302. A storage box 303 is arranged inside the storage box 301. The outer surface of the storage box 303 is provided with a magnet 304. A handle 305 is connected to the center position of the front surface of the storage box 303. The position and size of the magnet 304 match the position and size of the magnetic block 302.

[0027] The effect achieved by the entire embodiment 2 is that when it is necessary to store items such as spare high-pressure nozzles 212 or commonly used tools, the handle 305 can be grasped and pulled outward, so that the storage box 303 can be pulled out of the storage box 301, and commonly used items can be placed in the storage box 301 for storage. At this time, the magnetic block 302 will also play a role of firm fixation with the magnet 304, effectively preventing the storage box 303 from accidentally slipping out or shaking, thereby improving the convenience and overall practicality of storing commonly used items and enhancing the overall functionality of the device.

[0028] Working principle: when the sub-screen 4 needs to be cleaned after screening the crushed materials, the rotation function of the motor 205 can be turned on, and the first one-way screw 202 and the second one-way screw 208 are driven by the transmission belt 206 to drive the blowing frame 209 to move on the surface of the sub-screen 4 through threaded rotation, and the high-pressure nozzle 212 sprays high-pressure gas to blow away the dust and impurities on the surface of the sub-screen 4, thereby avoiding the time-consuming and labor-intensive manual cleaning problem and improving the cleaning efficiency of the sub-screen 4. When it is necessary to store spare high-pressure nozzles 212 or commonly used tools and other objects, the storage box 303 can be pulled out from the storage box 301 and placed in the storage box 301 for storage, thereby improving the convenience of storing commonly used items and improving the overall practicality.
