Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-3 , the utility model provides a technical solution:
[0019] A vibrating screen for screening fine sand comprises a screen frame 1, a feeding hopper 2 is connected to one side of the top of the screen frame 1, and a discharge square tube 3 is connected to the lower left position of the screen frame 1, a partition vertical plate 4 is provided on the inner side of the discharge square tube 3, and a conical platform 5 is integrally formed at the bottom end of the partition vertical plate 4, movable flaps 6 are provided at the lower positions on both sides of the conical platform 5, a horizontal support plate 7 is provided at the lower position of the front end of the discharge square tube 3, the movable flap 6 and the conical platform 5 are connected by a rotating shaft 17, and a limiting chuck 8 is provided on the outer sleeve of the front end of the rotating shaft 17, and a limiting sleeve 9 is provided on the outside of the limiting chuck 8, and telescopic rods 10 are provided on both sides of the horizontal support plate 7.
[0020] like Figure 1 and Figure 2 As shown, a coarse filter 12 is provided on the upper part of the screen frame 1, and a fine filter 11 is provided below the coarse filter 12. The fine filter 11 is arranged inside the screen frame 1, and one side end of the fine filter 11 is fixedly connected to the partition vertical plate 4. The upper half of the partition vertical plate 4 extends into the interior of the screen frame 1. By respectively arranging the coarse filter 12 and the fine filter 11, the multi-layer screening structure formed by the two will facilitate the entire vibrating screen to screen out coarse materials and fine materials in sequence; an external frame 14 is provided directly below the screen frame 1, and an inclined bucket 13 is provided in the middle of the bottom end of the screen frame 1, and a vibration motor 15 is fixedly installed at the lower right position of the inclined bucket 13. The vibration motor 15 is installed in an inclined structure. When the external frame 14 is against the bottom of the vibration motor 15 to provide auxiliary support thereto, the vibration motor 15 will transmit the vibration force generated after startup to the screen frame 1, so that it can realize the vibration screening operation; springs 16 are fixedly connected to both sides of the top of the external frame 14, and one end of the spring 16 is fixedly connected to the square plate member extending from the outside of the screen frame 1. When the entire vibrating screen realizes the screening operation of the sand material by vibration, the spring 16 will use the rebound potential energy generated by itself to provide elastic support to the screen frame 1, ensuring that it can realize continuous vibration screening operation.
[0021] like Figure 1 , Figure 2 and Figure 3As shown, the movable end of the telescopic rod 10 and the internal dimensions of the limiting sleeve 9 are adapted to each other, and the upper and lower positions of the telescopic rod 10 and the limiting chuck 8 are relatively set, the limiting chuck 8 is set at the front end lower position of the discharge square tube 3, the rotating connecting shaft 17 and the discharge square tube 3 are rotatably connected, and the front and rear ends of one side of the movable flap 6 are respectively fixedly connected with side guard bars 18, and a group of movable flaps 6 are set at the discharge port position of the discharge square tube 3. When fine materials and coarse materials are discharged outward along the slope of the movable flap 6 respectively, a group of front and rear side guard bars 18 will prevent sand materials from being discharged from the edge position from the front and rear positions.
[0022] Working process: The electric energy required for the startup and operation of the equipment of the utility model comes from an external power supply. When using the vibrating screen for screening fine sand, first, under the support of the external frame 14, start the vibration motor 15 to vibrate the inclined bucket 13 and the screen frame 1. At this time, as the coarse and fine mixture is gradually fed into the screen frame 1 through the inside of the feed hopper 2, the entire vibrating screen will first screen the coarse material in the mixture through the coarse filter screen 12, and then screen the fine material in the mixture through the fine filter screen 11 under the vibrating working state, so as to achieve the purpose of multi-layer graded screening. Then, the screened fine material and coarse material are respectively shaken out toward the lower left position from the coarse material inner cavity and fine material inner cavity formed inside the screen frame 1 and the discharge square tube 3. The fine material and coarse material will be discharged in different directions through the multi-channel discharge port structure provided at the bottom of the discharge square tube 3. Before considering using the vibrating screen, and when it is necessary to place the relative storage device below the discharge port, with the cooperation of manual operation, a group of movable flaps 6 can be adjusted to be flipped outward respectively, so that the two can be rotated 30° in opposite directions respectively, and the flipping after the flipping is effectively limited by the snap connection between the movable end of the telescopic rod 10 and the single limiting sleeve 9, and the pre-adjustment operation of a group of movable flaps 6 can be completed, which is also convenient for arranging a group of storage devices adjacent to each other. When the fine material and the coarse material are discharged outward from the two discharge ports pre-separated inside the discharge square tube 3, the fine material and the coarse material will be discharged outward in turn along the slope of a group of movable flaps 6 in a guided material distribution and diffusion manner, and accurately fall into a group of adjacently discharged storage devices, so as to avoid the phenomenon of mixing of fine sand and coarse material when they are discharged.
