On the other hand, after the screening platform has been used for a long time, the current method of cleaning the impurities clogging the screen mesh is mainly done manually, which is a cumbersome process and results in low cleaning efficiency of the screen mesh on the platform.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] like Figures 1-3As shown, a vibrating screening platform for mud and stone in this embodiment includes a base frame 3. A vibrating screening mechanism 4 is installed on one side of the top of the base frame 3. The vibrating screening mechanism 4 includes a screen frame 403 disposed on the upper side of the base frame 3. Telescopic rods 401 are installed between the four corners of the bottom end of the screen frame 403 and the base frame 3. Springs 404 are installed between the fixing part of the telescopic rods 401 and the bottom end of the screen frame 403. Vibrating motors 402 are installed on both sides of the bottom end of the screen frame 403. A screen mesh 40 is installed inside the screen frame 403. 5. A pre-crushing mechanism 1 is installed on the feed side of the screen frame 403. The pre-crushing mechanism 1 includes a crushing box 104 installed on the feed side of the screen frame 403. Two crushing rollers 102 are symmetrically installed inside the crushing box 104. A crushing motor 103 is installed on one side of the crushing box 104, directly opposite the crushing rollers 102. A discharge pipe 101 is installed at the discharge port of the crushing box 104. A moving mechanism 6 is also installed on the upper part of both side walls of the screen frame 403. The moving mechanism 6 includes components installed on one side of the screen frame 403. An electric slide rail 601 is mounted on the side wall, and a guide rail 603 is mounted on the other side wall of the screen frame 403. A mounting plate frame 602 is installed between the guide rail 603 and the electric slide rail 601. A high-pressure jetting mechanism 5 is mounted on the mounting plate frame 602. The high-pressure jetting mechanism 5 includes a high-pressure air pump 501 installed at the top center of the mounting plate frame 602 and a jetting hood 502 installed at the bottom center of the mounting plate frame 602. With the cooperation of the pre-crushing mechanism 1, the moving mechanism 6, and the high-pressure jetting mechanism 5, the mud and stone vibrating screening platform can not only pre-crush the mud and stone under the action of the pre-crushing mechanism 1, effectively avoiding the disadvantage of the mud and stone not being able to generate effective vibration during the screening process due to its large size, thus making the vibration screening effect of the mud and stone better, but also achieve automatic cleaning of the clogging impurities on the screen 405 under the action of the moving mechanism 6 and the high-pressure jetting mechanism 5, avoiding the tedious operation of manual cleaning and making the cleaning efficiency of the screen 405 higher.

[0018] like Figures 1-3 As shown in this embodiment, columns 2 are also installed between the lower part of the two side walls of the crushing box 104 and the base frame 3 by bolts. The columns 2 are mainly used to support the crushing box 104.

[0019] like Figures 1-3As shown, in this embodiment, the fixed part of the telescopic rod 401 is bolted to the base frame 3, and the telescopic part of the telescopic rod 401 is bolted to the bottom end of the screen frame 403. The telescopic part of the telescopic rod 401 passes through the inside of the spring 404. When the vibrating motor 402 is working, the screen frame 403 will vibrate up and down at high frequency under the action of the telescopic rod 401 and the spring 404, thereby using the screen 405 inside the screen frame 403 to efficiently vibrate and screen the mud and stones. The top end of the spring 404 is welded to the screen frame 403, and the bottom end of the spring 404 is welded to the top end of the fixed part of the telescopic rod 401. The screen 405 is bolted to the screen frame 403. A gap is reserved between the bottom of the screen 405 and the bottom of the screen frame 403, and the bottom of the screen frame 403 is a downward inclined structure. After the mud and stones are screened, the mud will fall into the bottom of the screen frame 403, while the stones will be removed by the external conveying mechanism on the upper side of the screen 405.

[0020] like Figures 1-3 As shown, in this embodiment, the crushing motor 103 is bolted to the crushing box 104, and the crushing motor 103 is connected to the crushing roller 102 by a coupling. The bottom of the crushing box 104 has an inclined downward structure, and a gap is reserved between the bottom of the discharge pipe 101 and the upper side of the screen frame 403. The crushing motor 103 drives the crushing roller 102 to rotate, which can pre-crush the mud and stone to ensure that the size of the mud and stone added into the screen frame 403 is appropriate.

[0021] like Figures 1-3 As shown, in this embodiment, the housing of the electric slide rail 601 is bolted to the screen frame 403, and the guide rail 603 is bolted to the screen frame 403. The electric slide rail 601 is mainly used to provide power for the reciprocating movement of the mounting plate frame 602. The guide rail 603 can ensure that the mounting plate frame 602 is more stable when sliding. The mounting plate frame 602 has a π-shaped structure and is bolted to the sliding block on the electric slide rail 601. The mounting plate frame 602 and the guide rail 603 slide together. The high-pressure air pump 501 and the spray nozzle 502 are bolted to the mounting plate 602. The bottom of the spray nozzle 502 has a nozzle with an angle of 15-30°. Research shows that the gas spraying effect is best when the nozzle angle is between 15-30°. After the high-pressure air pump 501 blows high-pressure gas into the spray nozzle 502, the high-pressure gas will be sprayed onto the screen 405 through the nozzle on the spray nozzle 502, thereby cleaning the screen 405.

[0022] The specific implementation process of this embodiment is as follows: When screening mud and stone, the screening platform is first connected to an external power supply and control components, and the mud and stone to be screened is put into the crushing box 104. When the mud and stone pass through the crushing box 104, they will be crushed under the action of the crushing motor 103 and the crushing roller 102. The crushed mud and stone will be discharged through the discharge pipe 101 onto the screen 405 on the screen frame 403. After the mud and stone fall onto the screen 405, they will vibrate up and down at a high frequency under the action of the vibrating motor 402, the telescopic rod 401 and the spring 404. During the vibration, the soil will fall into the lower part of the screen frame 403. The stones will remain on the upper side of the screen 405, and with the vibration, the stones and soil will be discharged. After discharge, the stones will be transported away by the external conveying mechanism, and the soil will also be removed and processed by the conveying mechanism. Under the action of this screening platform, not only is the disadvantage of the mud and stones being too large to generate effective vibration during the screening process effectively avoided, making the vibration screening effect of mud and stones better, but also the automatic cleaning of the impurities clogging the screen 405 can be achieved under the action of the moving mechanism 6 and the high-pressure jetting mechanism 5, avoiding the tedious operation of manual cleaning and making the cleaning efficiency of the screen 405 higher.

[0023] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
