Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of anti-clogging screening and mixing equipment, and in particular to an anti-clogging screening and mixing device for construction engineering. Background Technology
[0002] In the construction process, the screening and mixing of materials such as sand, gravel, and cement are crucial steps in ensuring project quality. However, traditional screening and mixing equipment often faces numerous technical challenges in practical applications. Because existing screening mechanisms mostly use fixed filter plates, the filter holes are easily clogged by uneven particle size and sticky substances during the screening process, resulting in a significant decrease in screening efficiency and requiring frequent shutdowns for cleaning, which seriously affects the construction progress. In addition, traditional filter plates lack flexible adjustment and vibration structures, making it difficult to adapt to the screening requirements of materials with different particle sizes, resulting in insufficient screening accuracy and thoroughness. On the other hand, the mixing mechanism and the screening mechanism often operate independently, and the material tends to accumulate when it enters the mixing area after screening, leading to uneven mixing and affecting the performance of subsequent construction materials. Therefore, the above problems need to be improved. Utility Model Content

The screening mechanism is supported by a limiting ring 5. The limiting ring 5 is equipped with a screening mechanism and a stirring mechanism. The stirring mechanism is located directly below the screening mechanism, and three sets of limiting mechanisms are installed at equal intervals on the outer side of the limiting ring 5. The stirring mechanism includes a spiral stirring disc 8 installed inside the limiting ring 5 and a motor 6 installed at one end of the support rod 2. The stirring disc 8 facilitates the mixing and stirring of materials. The motor 6 is located directly above the discharge port 3, and the output end of the motor 6 is connected to a rotating shaft 7 via a coupling. The rotating shaft 7 facilitates cooperation with the eccentric shaft 18 to improve screening efficiency. The center of the stirring disc 8 is connected to the rotating shaft 7.
[0015] In this invention, the screening mechanism includes a first filter plate 9 installed at the lower end of the inner wall of the limiting ring 5 and a second filter plate 10 rotatably installed on the bottom surface of the first filter plate 9. The first and second filter plates 9 and 10 facilitate control of the sieve hole size to accommodate materials of different sizes. A rotating groove is formed on the bottom surface of the first filter plate 9, and multiple positioning grooves are equidistantly formed around the circumference of the rotating groove. A positioning ring 11 is installed on the top surface of the second filter plate 10, facilitating the installation of positioning teeth 12. The positioning ring 11 is rotatably installed in the rotating groove, and multiple positioning teeth 12 are equidistantly installed on the bottom surface of the positioning ring 11, facilitating the limiting of the second filter plate 10. The positioning teeth 12 are inserted into the positioning grooves and are made of elastic rubber. An eccentric shaft is installed at the center of the first filter plate 9. 18. The eccentric shaft 18 is mounted on the rotating shaft 7, and the outer sides of the first filter plate 9 and the second filter plate 10 are both in contact with the inner wall of the limiting ring 5. The limiting mechanism includes a mounting block 13 mounted on the inner wall of the main body 1, through which the connecting rod 14 is easily installed; the connecting rod 14 is hinged on the mounting block 13, through which the sleeve 15 is easily installed; the other end of the connecting rod 14 is hinged to the sleeve 15, and the other end of the sleeve 15 is inserted into the telescopic rod 16, through the cooperation of the sleeve 15, the spring 17 and the telescopic rod 16 to restrict the movement trajectory of the limiting ring 5; the other end of the telescopic rod 16 is hinged to the outer side of the limiting ring 5, and the spring 17 is installed inside the sleeve 15, one end of the spring 17 abuts against one end of the inner wall of the sleeve 15, and the other end of the spring 17 abuts against one end of the telescopic rod 16.
[0016] Working Principle: When using this invention, first, the device is powered on. This provides power to all components. Then, the material to be processed is fed into the main body 1 through the feed inlet 3 at the top. The feed inlet 3 ensures a continuous and stable flow of material into the equipment, preparing for subsequent screening and mixing processes. After material feeding, the motor 6 (located directly above the feed inlet 3) installed at one end of the support rod 2 is started. The output of the motor 6 drives the rotating shaft 7 to rotate via a coupling. Since the center of the mixing disc 8 is connected to the rotating shaft 7, the rotation of the shaft 7 directly drives the spiral mixing disc 8 inside the main body 1. The rotating mixing disc 8 thoroughly mixes the input materials, ensuring initial uniformity. Simultaneously with the rotation of the rotating shaft 7, the eccentric shaft 18 mounted on its upper end rotates. The eccentric shaft 18 is connected to the center of the first filter plate 9, causing the first filter plate 9 to move eccentrically. Since the second filter plate 10 is rotatably mounted on the bottom surface of the first filter plate 9, the movement of the first filter plate 9 drives the second filter plate 10 to move synchronously, causing the entire screening mechanism to vibrate and thus screening the materials. During the movement of the second filter plate 10, the positioning ring 11 mounted on its top surface rotates within a groove on the bottom surface of the first filter plate 9. Multiple positioning teeth 12 (made of elastic rubber) equidistantly mounted on the bottom surface of the positioning ring 11 circumferentially rotate around the groove. The second filter plate 10 moves within the positioning groove. This structure ensures stable rotation of the second filter plate 10 during vibration, effectively preventing screen hole blockage and ensuring smooth screening. Simultaneously, the outer sides of both the first and second filter plates 9 and 10 abut against the inner wall of the limiting ring 5. The limiting ring 5 provides auxiliary support to the screening mechanism, further improving screening stability. During vibration, the limiting mechanism buffers the vibration. In the limiting mechanism, a connecting rod 14 is hinged to the mounting block 13 mounted on the inner wall of the main body 1. A sleeve 15 is hinged to the other end of the connecting rod 14. A telescopic rod 16, inserted inside the other end of the sleeve 15, is hinged to the outer side of the limiting ring 5, forming a three-point hinge structure. During vibration, the telescopic rod 16 moves within the sleeve... The internal extension of sleeve 15 compresses the spring 17 installed inside sleeve 15 (one end of spring 17 abuts against one end of the inner wall of sleeve 15, and the other end abuts against one end of extension rod 16). The elasticity of spring 17 buffers the impact force generated by vibration, reduces the hard collision between the screening mechanism and the main body 1, protects the equipment, and extends the service life of the equipment. The material after screening and mixing is collected at the bottom of the main body 1 under the action of gravity and is finally discharged through the discharge port opened at the lower end of the front face of the main body 1. The guide platform 4 (with an inclined section) installed inside the discharge port guides the material to be smoothly discharged from the equipment. After all the material is discharged, the power is turned off, the entire equipment stops running, and one screening and mixing operation is completed. The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
