DETAILED DESCRIPTION

[0021] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0022] like Figures 1 to 4As shown, a vibrating screen provided by an embodiment of the present invention includes a base 1, a vibrating screen body, a material receiving box 6 and a vibrating motor 4;

[0023] The vibrating screen body is mounted on the base 1 via a number of elastic support members 5. The vibrating screen body of this embodiment includes a screen plate 2 and a slag receiving plate 3. Screen holes are provided on the screen plate 2. The slag receiving plate 3 is located below the screen plate 2. The vibrating screen body is in an inclined state so that the material can be automatically discharged along the inclined surface of the screen plate 2 and the slag can be automatically discharged along the inclined surface of the slag receiving plate 3.

[0024] The discharge port of the vibrating screen body is inward-retracted;

[0025] The vibration motor 4 is fixedly mounted on the base 1, and its output end can contact the vibration screen body, so that the vibration screen body is shaken by the vibration motor 4, thereby achieving the purpose of screening out the debris. In this embodiment, two vibration motors 4 are selected to work simultaneously to improve the screening efficiency;

[0026] The elastic support member 5 of this embodiment includes a mounting seat 1 7, a mounting seat 2 8, a connecting seat 9, a connecting rod 10, a connecting rod 2 11 and a spring 12, wherein the mounting seat 1 7 and the mounting seat 2 8 are fixedly connected to the vibrating screen body and the base 1 respectively, one end of the connecting rod 10 is hinged to the mounting seat 1 7, and the other end is hinged to the connecting seat 9, one end of the connecting rod 2 11 is hinged to the mounting seat 2 8, and the other end is hinged to the connecting seat 9, and the spring 12 is located between the mounting seat 1 7 and the mounting seat 2 8;

[0027] The base 1 is provided with a material receiving seat 13 that cooperates with the material receiving box 6 to prevent the material receiving box 6 from falling off during vibration;

[0028] In addition, the screen plate 2 is provided with several groups of material blocking members, each of which has a spacing that allows the material to pass through, and the spacing between the several groups of material blocking members increases along the inclination direction of the vibrating screen body;

[0029] Specifically, the vibrating screen body of this embodiment is provided with three groups of material blocking members distributed along the inclination direction thereof, the first group of material blocking members includes three material blocking bars 14, wherein a first spacing 17 is provided between two adjacent material blocking bars 14, the second group of material blocking members includes one material blocking bar 15, and a second spacing 18 is provided between the two ends of the material blocking bar 15 and the two sides of the vibrating screen body, the third group of material blocking members includes two material blocking bars 16, and a third spacing 19 is provided between the two material blocking bars 16, the first spacing 17 is smaller than the second spacing 18, and the second spacing 18 is smaller than the third spacing 19;

[0030] The cross-sections of the first blocking bar 14, the second blocking bar 15 and the third blocking bar 16 are all triangular, which can block part of the slag, while the whole piece of material can pass through under shaking, so as to keep the slag on the screen plate 2 as much as possible or fall onto the slag receiving plate 3;
