[0020] As Figure 1 and 2 shown,

[0021] As an optional embodiment,

[0022] A new type of ore vibrating screen includes a housing 1, a feed hopper 2 is installed on the housing 1, a discharge hopper 6 is provided on the side of the housing 1, a sieve plate assembly is arranged inside the housing 1, one end of the sieve plate assembly close to the discharge hopper 6 is hinged on the inner wall of the housing 1, a connecting shaft 17 is installed on the side wall of the sieve plate assembly far from the discharge hopper 6, a first bottom plate 10 is installed on the side of the housing 1, a height adjustment assembly is installed on the first bottom plate 10, and the top of the height adjustment assembly is hinged on the connecting shaft 17.

[0023] In the above structure, during use, materials are put into the feed hopper 2, and the feed hopper 2 discharges materials to the sieve plate assembly at a uniform speed. After discharging, an external vibration device drives the sieve plate assembly to vibrate, so that the materials falling on the inclined sieve plate assembly continuously move towards one end of the discharge hopper 6. The materials that do not pass through the sieve plate assembly are discharged through the discharge hopper 6 because the material volume is large, while the materials that pass through the sieve plate assembly enter the channel below the sieve plate assembly and flow into the next process, thus completing its screening work.

[0024] Among them, the designed height adjustment component uses the bottom plate as a support. The height adjustment component pushes the sieve plate component to flip. When flipping, the connection between the sieve plate component and the housing 1 is the rotation center. When the height adjustment component pushes up the end of the sieve plate component away from the discharge hopper 6, the inclination of the sieve plate component continuously increases. Thus, when screening materials subsequently, the flow rate of the materials can be more reasonably controlled to avoid the problem of low screening efficiency of the materials caused by too fast or too slow material flow rate. In addition, since the sizes of the materials are different, their own flow rates will also vary. By controlling the height adjustment component, the inclination of the sieve plate component can be changed in real time without stopping to adjust the inclination of the sieve plate component, which is convenient and efficient.

[0025] The following two structures are designed for the above-mentioned height adjustment component:

[0026] The structure of the first height adjustment component is as follows:

[0027] The height adjustment component is a telescopic rod. The bottom end of the telescopic rod is hinged on the first bottom plate 10, and the top end of the telescopic rod is rotatably connected to the connecting shaft 17. The telescopic rod can be an electric telescopic rod. Subsequently, by controlling the telescopic rod to change its own length, the telescopic rod pushes or pulls the sieve plate component upward with the first bottom plate 10, so that the sieve plate component rotates around the connection between the sieve plate component and the housing 1, changing the inclination of the sieve plate component.

[0028] The structure of the second height adjustment component is as follows:

[0029] As shown in the figure, the height adjustment component includes a box body 11, and a first connecting rod 8, a second connecting rod 9, a first bearing member 13, a first internal thread sleeve 14, a second internal thread sleeve 15 and a first lead screw 16 arranged inside the box body 11. The two ends of the first lead screw 16 are connected to the first bottom plate 10 through the first bearing member 13. The first internal thread sleeve 14 and the second internal thread sleeve 15 are both sleeved on the first lead screw 16 that is in threaded cooperation with them. One end of the first connecting rod 8 is hinged on the first internal thread sleeve 14, one end of the second connecting rod 9 is hinged on the second internal thread sleeve 15, the other ends of the first connecting rod 8 and the second connecting rod 9 are jointly rotatably connected to the connecting shaft 17, and a third strip-shaped groove 1101 for the activities of the first connecting rod 8 and the second connecting rod 9 is opened at the top of the box body 11.

[0030] When it is necessary to raise the sieve plate assembly, only the first lead screw 16 needs to be rotated. When the first internal thread sleeve 14 and the second internal thread sleeve 15 on the first lead screw 16 approach synchronously, the first connecting rod 8 and the second connecting rod 9 jointly push the sieve plate assembly connected by the connecting shaft 17 to move upward together. Among them, the third strip-shaped groove 1101 opened on the box body 11 is used to restrict the movement range of the first connecting rod 8 and the second connecting rod 9, and provide a certain support for the first connecting rod 8 and the second connecting rod 9 during the movement process, so that the sieve plate assembly rotates around the connection point with the housing 1 as the rotation center, and the other end of the sieve plate assembly rises, thereby changing the inclination of the sieve plate assembly.

[0031] A first motor 12 is arranged inside the box body 11. The first motor 12 is fixedly connected to the first bottom plate 10. The rotating shaft of the first motor 12 is connected to the first lead screw through a coupling. The first motor 12 is selected as the drive to complete the rotation of the first lead screw. Subsequently, controlling the start and stop of the first motor 12 can achieve the purpose, without the need for manual rotation of the first lead screw, reducing the overall working intensity.

[0032] Improvements have been made to the sieve plate assembly: The sieve plate assembly includes a frame body 3, a reinforcing rib 4, and a sieve mesh plate 5. The sieve mesh plate 5 is arranged in the frame body 3. Reinforcing ribs 4 for supporting the sieve mesh plate 5 are arranged in the frame body 3. Both ends of the reinforcing rib 4 are connected to the inner wall of the frame body 3. One end of the frame body 3 close to the discharge hopper 6 is hinged to the inner wall of the housing 1. The connecting shaft 17 is connected to the frame body 3. The frame diagram is rectangular. The reinforcing rib 4 is columnar and installed inside the frame body 3, which can strengthen the stability of the frame body 3. On the other hand, when the sieve mesh plate 5 is placed in the frame body 3, the reinforcing rib 4 provides a certain support, enhancing the load-bearing capacity of the sieve mesh plate 5.

[0033] A first strip-shaped groove 301 is opened on the side of the frame body 3. A first strip-shaped plate 7 is vertically installed on the side of the housing 1. A second strip-shaped groove 701 is opened on the first strip-shaped plate 7. The connecting shaft 17 is inserted into the first strip-shaped groove 301 and the second strip-shaped groove 701. Among them, when the connecting shaft 17 rises, the connecting shaft 17 slides upward in the second strip-shaped groove 701. At the same time, the connecting shaft 17 slides towards the end away from the discharge hopper 6 in the first strip-shaped groove 301. By limiting the movement distance of the connecting shaft 17, the movement range of the sieve plate assembly is finally restricted.

[0034] An arc-shaped plate 101 is installed on the inner wall of the housing 1. The arc-shaped plate 101 is slidably connected to the frame body 3. Since one end of the frame body 3 close to the discharge hopper 6 is hinged to the housing 1, during the process of lifting the frame body 3, the movement trajectory of the end of the frame body 3 away from the discharge hopper 6 is an arc-shaped movement. Therefore, an arc-shaped plate 101 is selected to be installed on the inner wall of the housing 1 to ensure that the gap between the frame body 3 and the housing 1 is smaller, so as to prevent materials that cannot pass through the sieve mesh plate 5 from passing through this gap.

[0035] Working principle:

[0036] Start the first motor 12 in the starting box body 11. The rotating shaft of the first motor 12 drives the first lead screw 16 to rotate in the box body 11, thereby pushing the first internal thread sleeve 14 and the second internal thread sleeve 15 closer to each other on the first lead screw 16. When the two internal thread sleeves are close to each other, the first connecting rod 8 and the second connecting rod 9 push the frame body 3 connected by the connecting shaft 17 to move upward. During the upward movement, the connecting shaft 17 moves upward in the second strip-shaped groove 701 and also moves leftward in the first strip-shaped groove 301. And the frame body 3 itself rotates clockwise with the hinge point with the housing 1 as the center and its own length as the radius. Thus, the horizontal height of the feeding end of the screen plate 5 is gradually greater than the horizontal height of the discharging end of the screen plate 5, and this height difference continuously expands. The flow rate of the material screening can be changed, and an appropriate inclination can be selected according to different materials, and the purpose of rapid screening can be achieved.

[0037] The above embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
