This facilitates the replacement of the screening plates, preventing stone from falling and causing damage, thus affecting the service life of the device.

[0004] Currently, some screening devices use fixed screen connections. When replacing the screening plate, there is a time difference between the removal of the old screening plate and the installation of the new screening plate. At the same time, the disassembly and assembly steps are complicated, which reduces the continuous separation efficiency of stone. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as the time gap between removing the old screening plate and installing the new screening plate, which makes seamless replacement impossible and requires stopping screening, thus affecting the stone separation efficiency. Therefore, this invention proposes a stone separation vibrating screen.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a vibrating screen for stone separation, including a frame, a screen frame mounted on the frame via an elastic component, and a vibrating motor fixed to the side of the screen frame; The screen frame has an internal and an external mounting frame, and the two mounting frames are rotatably connected by a coupling component. The screen plate is installed inside the mounting frame by a limiting component.

[0007] Furthermore, the limiting component includes a limiting groove opened at the top of the mounting frame, and a screening plate is installed inside the limiting groove. A plurality of limiting posts are fixed on the bottom wall of the limiting groove, and the upper ends of the plurality of limiting posts penetrate the screening plate.

[0008] Furthermore, the guiding component includes a guide frame fixed inside the screen frame, with both the left and right ends of the guide frame extending through and out of the screen frame, and the bottom of the guide frame and the inner bottom surface of the screen frame forming a guide groove for the mounting frame to pass through.

[0009] Furthermore, the guide frame has a rectangular frame structure; The guide frame has a stop portion bent downward on both horizontal sides along the insertion direction of the mounting frame, and the stop portion is fixed to the inner bottom surface of the screen frame.

[0010] Furthermore, the positioning component includes two pairs of fixing plates respectively fixed on both sides of the screen frame. An elastic metal plate is fixedly connected to the end face of one pair of fixing plates away from each other. A retaining strip is fixed to the end face of the other pair of elastic metal plates close to each other, and the inclined surface of the retaining strip is located at the end away from the fixing plate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 As an embodiment of the present utility model, a stone separation vibrating screen is disclosed. Specifically, the vibrating screen includes a frame 10, a screen frame 1 mounted on the frame 10 through an elastic component 3, and a vibrating motor 2 fixed to the side of the screen frame 1. Preferably, the elastic component 3 can be configured as a spring fixed between the frame 10 and the screen frame 1. The springs can be distributed in a matrix of four. When the vibration motor 2 drives the screen frame 1 to vibrate, the springs provide the vibratory displacement of the screen frame 1. In addition, the screen frame 1 is installed at an angle on the frame 10. The screen frame 1 has an installation frame 4 installed inside and outside, and the two installation frames 4 are rotatably connected by a coupling member 7. In a preferred embodiment, the coupling member 7 can be set as a hinge. The screen plate 6 is installed inside the installation frame 4 by a limiting component 5. The horizontally arranged mounting frame 4 is slidably installed inside the screen frame 1 via the guide component 8, and the vertically arranged mounting frame 4 is fixedly installed on the side of the screen frame 1 via the positioning component 9.

[0018] The guide component 8 enables the mounting frame 4 to move left and right within the screen frame 1, thereby allowing the old and new screening plates 6 within the two mounting frames 4 to move horizontally for quick switching without stopping screening. The positioning component 9 fixes the outer mounting frame 4, thereby positioning the mounting frame 4 in the left and right directions and keeping the mounting frame 4 vertical to reduce the floor space occupied.

[0019] In some embodiments, the limiting component 5 of this utility model includes a limiting groove 51 opened at the top of the mounting frame 4, and a screening plate 6 is installed inside the limiting groove 51. A plurality of limiting posts 52 are fixed on the bottom wall of the limiting groove 51, and the upper ends of the plurality of limiting posts 52 penetrate the screening plate 6. That is, in this embodiment, the screening plate 6 is fixed by inserting the limiting posts 52 into the screening plate 6. Of course, in order to further fix the screening plate 6, in this embodiment, the limiting posts 52 can also be set as screws. When they penetrate the screening plate 6, they can be connected and pressed onto the screening plate 6 by a nut threaded on, so as to further fix the screening plate 6.

[0020] Furthermore, in this embodiment, the guide component 8 includes a guide frame 81 fixed inside the screen frame 1, and both the left and right ends of the guide frame 81 extend through and out of the screen frame 1. The bottom of the guide frame 81 and the inner bottom surface of the screen frame 1 form a guide groove for the mounting frame 4 to pass through.

[0021] Specifically, in this embodiment, the guide frame 81 has a rectangular frame structure; On both horizontal sides of the guide frame 81 along the insertion direction of the mounting frame 4, there are stop parts 82 bent downwards. The stop parts 82 are fixed to the inner bottom surface of the screen frame 1. The two stop parts 82 are horizontally arranged. Their purpose is to limit and guide the two sides of the mounting frame 4. When the mounting frame 4 is inserted, it can enter the interior of the screen frame 1 along the guide groove.

[0022] The stop part 82 ensures that the inner mounting frame 4 can only move left and right but not back and forth, so that when the mounting frame 4 is replaced, the two mounting frames 4 will not move back and forth due to tilting and the impact of the stone.

[0023] Based on the above embodiments, the positioning component 9 in this embodiment includes two pairs of fixing plates 91 respectively fixed on both sides of the screen frame 1. An elastic metal plate 92 is fixedly connected to the end face of the pair of fixing plates 91 away from each other. The elastic metal plate 92 can be made of stainless steel or spring steel. A retaining strip 93 is fixed to the end face of the pair of elastic metal plates 92 close to each other, and the inclined surface of the retaining strip 93 is located at the end away from the fixing plate 91. Both ends of the vertically arranged mounting frame 4 are clamped between the retaining strip 93 and the fixing plate 91.

[0024] For example, in this embodiment, the cross-section of the card strip 93 is a right triangle, and the inclined surface of the card strip 93 where the hypotenuse of the triangle is located is on the side away from the corresponding fixing plate 91. The inclined surface makes it easy for the card strip 93 to be automatically squeezed to both sides by squeezing the inclined surface when the mounting frame 4 is rotated vertically.

[0025] Before replacing the screening plate 6, push the front ends of a pair of elastic metal plates 92 toward both sides of the mounting frame 4, so that the outer ends of the pair of elastic metal plates 92 bend to both sides and drive the locking strip 93 to disengage from the mounting frame 4, thereby flattening the mounting frame 4 on the side of the screen frame 1 and installing the screening plate 6 in the limiting groove 51 of the mounting frame 4. After installation, push the two mounting frames 4 to the other side so that the mounting frame 4 with the new screening plate 6 installed is pushed into the screen frame 1 and the mounting frame 4 with the old screening plate 6 installed is squeezed out of the screen frame 1, thus completing the seamless switching between the new and old screening plates 6. After switching, remove the old screening plate 6 and rotate the mounting frame 4 on the outside of the old screening plate 6 to be vertical. At the same time, the rotating mounting frame 4 squeezes the inclined surfaces of a pair of clamping strips 93, thereby squeezing the outer ends of the clamping strips 93 and a pair of elastic metal plates 92 to both sides until the mounting frame 4 is vertical and fits against the fixing plate 91. Then, the pair of elastic metal plates 92 return to their original position and drive the clamping strips 93 to move to the outside of the mounting frame 4, thereby cooperating with the fixing plate 91 to clamp and fix the mounting frame 4, thus preventing the mounting frame 4 inside the screen frame 1 from moving left and right.

[0026] It should be noted that the screen frame 1 described in this utility model is a rectangular frame structure with openings at the top and bottom. The front end of the screen frame 1 has a discharge port. During operation, the stone is placed on the upper side of the screening plate 6, and the screen frame 1 is vibrated by the vibration motor 2. At this time, the qualified stones fall down along the mesh of the screening plate 6, and the large stones flow to the lower side of the screen frame 1 and are discharged and separated from the discharge port. Of course, a baffle can also be fastened at the discharge port with bolts to maintain continuous screening.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
