[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0029] like Figures 1 to 3 As shown, the embodiment of the present invention provides a vibrating screen 5 filtering device for continuously conveying raw materials for producing rice noodles, comprising a frame 1, a feeding fan 2, a guide cylinder 3, a shearing and mixing mechanism 4, a vibrating screen 5 and a discharging cylinder 6, wherein the vibrating screen 5 is arranged on the frame 1, the guide cylinder 3 is connected to the top of the vibrating screen 5, the guide cylinder 3 is used to convey the rice noodle raw materials into the vibrating screen 5 for screening and filtering, the feeding fan 2 is connected to the guide cylinder 3 through a feeding pipe 21, the feeding fan 2 is used to convey the rice noodle raw materials into the guide cylinder 3, the shearing and mixing mechanism 4 The shearing and mixing mechanism 4 is arranged in the guide barrel 3, and the shearing and mixing mechanism 4 is used to evenly break up the rice noodle raw materials; the feeding fan 2 transports the rice noodle raw materials from the external storage device to the guide barrel 3 through the feeding pipe 21, and the guide barrel 3 is provided with a shearing and mixing mechanism 4. The shearing and mixing mechanism 4 can break up the lumps in the rice noodle raw materials and mix them evenly through shearing and stirring, thereby preventing the rice noodle raw materials from affecting the screening effect due to lumps when entering the vibrating screen 5. The rice noodle raw materials treated with shearing and mixing can be transported to the vibrating screen 5, and the vibrating screen 5 can screen the rice noodle raw materials through vibration.

[0030] like Figure 3As shown, the vibrating screen 5 includes a circular screen drum 51, a screening mesh 52, a vibration motor 53 and a buffer spring 54. The bottom of the circular screen drum 51 is connected to the frame 1 through the buffer spring 54. The circular screen drum 51 has a positioning frame 510 inside, and the screening mesh 52 is arranged on the positioning frame 510. The screening mesh 52 is provided with a plurality of filter holes 520, and the screening mesh 52 is provided with a plurality of concentrically arranged limit rings 521 along the circumferential direction. Two vibration motors 53 are provided on both sides of the circular screen drum 51. The vibration motor 53 is used to drive the circular screen drum 51 to vibrate. The discharge drum 6 is connected to the bottom of the circular screen drum 51, and the discharge drum 6 is used to collect the rice flour raw materials that have been screened and filtered. After the vibration motor 53 is started, it can drive the circular screen drum 51 to vibrate, causing the rice noodle material to continuously move and jump on the screening mesh 52, promoting the screening process. The setting of the limit ring 521 can evenly distribute the rice noodle material on the screening mesh 52, preventing the material from being excessively concentrated in a certain area on the surface of the screening mesh 52, thereby avoiding overload or blockage in some areas and improving the screening effect. The buffer spring 54 can absorb the impact force generated during the vibration process, reducing the impact of vibration on the equipment, thereby extending the service life of the equipment.

The vertically arranged mixing blade 44 can better push and stir the material, making it evenly distributed and preventing the material from accumulating in a certain area; the obliquely arranged shearing blade 45 can apply shear force to the material during rotation, thereby breaking up lumps in the rice noodle raw material.

[0034] like Figure 2 As shown, further, a stirring blade 431 is provided on the top of the spiral rod 43. Such a configuration allows the rice noodle raw materials to be preliminarily stirred and mixed before entering the spiral rod 43, so that the rice noodle raw materials can flow downward smoothly.
