Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0025] Embodiment 1:

[0026] Please refer to Figure 1-3A vibrating screen plate structure of a vibrating screen comprises a bottom plate 1, a lifting mechanism for up and down vibration is installed on the top of the bottom plate 1; a working mechanism for left and right vibration is installed on the top of the lifting mechanism, and the working mechanism comprises a working box body 2, a first motor 3 is fixedly connected to the back of the working box body 2, a rotating rod 4 is fixedly connected to the front of the output shaft of the first motor 3, and the first motor 3 provides driving force for left and right vibration.

[0027] The first motor 3 is rotatably connected to the rotating rod 4 through a coupling, a cam 5 is fixedly connected to the outer ring of the rotating rod 4, and a screening box 6 is installed in the inner cavity of the working box 2. A sliding groove 7 is opened on one side of the screening box 6, and the cam 5 slides in the inner cavity of the sliding groove 7. The cam 5 and the sliding groove 7 are both provided with two groups and are symmetrically distributed.

[0028] In the embodiment of the utility model, the first motor 3 is started, and the first motor 3 drives the rotating rod 4 to rotate. Since the cam 5 is fixedly connected to the rotating rod 4, the cam 5 will rotate with the rotation of the rotating rod 4, and the cam 5 is slidably connected to the screening box 6. When the protrusion of the cam 5 contacts the inner wall of the sliding groove 7, the screening box 6 can be pushed to the left.

[0029] Embodiment 2:

[0030] Please refer to Figure 1-4 A first telescopic rod 8 is fixedly connected in the inner cavity of the working box 2, the first telescopic rod 8 is fixedly connected to the screening box 6, and a first spring 10 is fixedly connected between the first telescopic rod 8 and the screening box 6.

[0031] A feed pipe 11 is fixedly connected to the top of the working box 2, a collection cabinet 12 is slidably connected to the inner cavity of the working box 2, a screening plate 13 is fixedly connected to the inner cavity of the working box 2, a second motor 14 is fixedly connected to the back of the working box 2, a one-way screw 15 is fixedly connected to the front of the output shaft of the second motor 14, a moving block 16 is threadedly connected to the outer ring of the one-way screw 15, and a cleaning brush 17 is fixedly connected to one side of the moving block 16. A limit rod 18 is fixedly connected to the inner cavity of the working box 2, the limit rod 18 is inserted into the inner cavity of the moving block 16, and the limit rod 18 is provided with two groups of horizontal distribution.

[0032] The lifting mechanism includes a second telescopic rod 19 , an outer ring of the second telescopic rod 19 is sleeved with a second spring 20 , the second telescopic rod 19 and the second spring 20 are both arranged with multiple groups of rectangular array distribution, and a vibration motor 21 is fixedly connected to the bottom of the working box 2 .

[0033] In the embodiment of the utility model, the second motor 14 is started, and the second motor 14 drives the one-way screw 15 to rotate. Since the moving block 16 is threadedly connected to the outer ring of the one-way screw 15, the moving block 16 moves back and forth as the second motor 14 is started.

[0034] When in use, first pour the material to be screened through the feed pipe 11, then start the vibration motor 21, and the vibration motor 21 drives the working box 2 to vibrate and screen. Since the bottom plate 1 and the working box 2 are fixed by the second telescopic rod 19 and the second spring 20, when the vibration motor 21 is started, the extension and contraction of the second telescopic rod 19 and the second spring 20 can improve the vibration and screening effect of different grades of materials.

[0035] In order to increase the screening rate of the material, the first motor 3 is started, and the first motor 3 drives the rotating rod 4 to rotate.

With the rotation of the cam 5, the screening box 6 is reciprocated in the left and right directions, and the vibration lifting in the vertical direction can increase the screening rate of the device for materials.

[0036] The material screened by the screening box 6 will fall onto the top of the screening plate 13 under the influence of gravity for secondary screening. After the screening is completed, the material will be collected by the collection cabinet 12 for easy removal by the staff. Since the material with larger particles may block the screening holes, the second motor 14 is started at this time, and the second motor 14 drives the one-way screw 15 to rotate. Since the moving block 16 is threadedly connected to the outer ring of the one-way screw 15, the moving block 16 will move back and forth with the start of the second motor 14, and drive the cleaning brush 17 to move back and forth. Starting the second motor 14 can drive the cleaning brush 17 to move back and forth, and clear the blocked area of ​​the screening plate 13 to avoid that some areas of the screening plate 13 cannot be used due to the blockage of materials, thereby improving the practicality of the device.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit thereof, and that the scope of the present invention is defined by the appended claims and their equivalents.
