DETAILED DESCRIPTION

[0019] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0020] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 、 Figure 2 and Figure 3 As shown, a high-frequency vibration screening machine of the present invention comprises a screening box 1 and a screening plate 12, a feed port 2 is obliquely provided on the top surface of the screening box 1, a discharge port 3 is obliquely provided on the bottom surface of the screening box 1, the feed port 2 and the discharge port 3 are obliquely arranged relative to each other, the screening plate 12 is installed inside the screening box 1, a plurality of screening ports 15 are provided on the screening plate 12, a rotating shaft 13 is provided at one end of the screening plate 12, a clearing rod 14 for removing blockages inside the screening port 15 is installed at the outer ring surface of the rotating shaft 13 facing the screening port 15, a positioning port is provided on the top surface of the screening box 1 on one side of the feed port 2, a baffle 4 is inserted into the positioning port, and the bottom surface of the baffle 4 conflicts with the upper surface of the screening plate 12.

[0023] In this embodiment, a plurality of positioning grooves 8 are vertically provided on one side surface of the baffle 4, and positioning blocks 9 are installed at the inner wall surface of the positioning opening facing the positioning grooves 8. The positioning blocks 9 are slidably installed in the positioning grooves 8, and compression springs 5 ​​are installed on the top surfaces of the positioning blocks 9. The other ends of the compression springs 5 ​​are installed on the top surfaces of the positioning grooves 8.

[0024] Among them, during the clockwise rotation of the clearing rod, the clearing rod can push the baffle upward, so that the baffle moves upward along the positioning port, thereby avoiding obstruction. After the clearing rod passes, the baffle can be automatically pushed back to its original position through the rebound of the compression spring, thereby blocking the screened material.

[0025] In this embodiment, the outer ring surface of the screening box 1 is provided with a mounting opening facing the screening plate 12, and a vibrator 11 connected to the screening plate 12 is installed in the mounting opening. A space for the cleaning rod 14 to rotate clockwise is formed between the end of the screening plate 12 away from the vibrator 11 and the screening box 1.

[0026] In this embodiment, a plurality of support seats 7 are installed on the bottom surface of the screening box 1; both sides of the screening plate 12 in the length direction are installed on the inner side surface of the screening box 1, and the screening box can be placed on the ground at an angle through the support seats.

[0027] In this embodiment, the width of the screening port 15 matches the width of the cleaning rod 14, so that the cleaning rod can just pass through the screening port and perform a comprehensive impurity removal operation on the screening port at one time.

[0028] In this embodiment, the screening plate 12 and the baffle 4 are both inclined, and the degree of inclination is the same as that of the feed port 2 and the discharge port 3, so that the poured material is accumulated on the left side of the screening plate. A baffle is provided on the right side of the screening plate to prevent the material from directly entering the interior of the screening box along the open port on the right side of the screening plate.

[0029] In this embodiment, sealed bearings are embedded in the centers of both sides of the screening box 1, a shaft is installed at one end of the rotating shaft 13, and the other end of the shaft is installed in the inner ring of the sealed bearing on one side. A reduction motor 6 is installed on the other side of the screening box 1, and the rotating shaft of the reduction motor 6 passes through the inner ring of the sealed bearing on the other side and is fixedly connected to the other end face of the rotating shaft 13, so that the rotating shaft can only rotate along the shaft as the center, thereby increasing the positioning effect of the rotating shaft.

[0030] Among them, the feed port, discharge port and screening plate are all inclined, so that the material poured through the feed port is close to the left side of the screening plate, avoiding flowing to the right and directly entering the interior of the screening box. After the vibrator is started, the vibration energy of the vibrator acts on the screening plate, and the vibration energy of the screening plate enables the material to pass smoothly through the screening port, so that the material can be screened.

[0031] During the screening process, the reduction motor can be started, and the start of the reduction motor drives the rotating shaft. The rotation of the rotating shaft drives the cleaning rod, causing the cleaning rod to rotate clockwise. When the cleaning rod passes through the screening port from bottom to top, it can directly push the impurities in the screening port upward, avoiding blockage, thereby ensuring the quality of screening and increasing the efficiency of screening.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that do not require creative effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
