Technical Field
[0001] This utility model relates to the field of water drilling technology, specifically a combined screening device. Background Technology
[0002] Rhinestones typically refer to small beads or stone-like ornaments made of crystal glass or plastic. They mimic the appearance of diamonds, possessing a high refractive index and a sparkling luster, and are widely used in the decoration of jewelry, clothing, shoes, bags, phone cases, and other products. The name "rhinestone" comes from its clear, water-like appearance. In the rhinestone processing, a sieving device is one of the most important pieces of equipment. It is used to classify diamonds of different sizes according to their dimensions. The sieving device ensures product consistency and quality control. Vibrating screens are one of the most commonly used sieving devices. They generate high-frequency vibrations to force diamond particles through the screen, thereby achieving the purpose of grading by size. In the process of developing this utility model, the inventors discovered the following problems with the existing technology:
[0003] 1. Many existing vibrating screens only have one screen surface, which can only divide the material into two parts: fine material passing through the screen and coarse material remaining on the screen surface. They cannot achieve multi-stage screening and cannot complete multiple levels of screening at the same time.
[0004] 2. The screen and screen frame of the vibrating screen are integrated and cannot be separated. Different materials may require screens with different apertures or types. If the screen and screen frame are fixed together, the entire component must be replaced when the screening specifications need to be changed, which lacks flexibility. Utility Model Content
[0005] The purpose of this utility model is to provide a combined screening device to solve the problems mentioned in the background art, namely, the inability to achieve multi-stage screening and the inability to disassemble and replace the screen without changing its shape. To achieve the above objective, this utility model provides the following technical solution: a combined screening device, including a fixed frame, wherein a screening component and a guide plate are installed inside the fixed frame, and a drive component is installed on one side of the screening component.
[0006] The screening assembly includes a screen frame, a screen plate inserted inside the screen frame, a tension spring sleeved on the outside of the screen frame, a slide rod welded to the bottom of the screen frame, a ball embedded in the bottom of the slide rod, a track slidably connected to the outside of the slide rod, bolts threadedly connected to the front and back of the screen frame, and a side plate slidably connected to the side of the screen frame.
[0007] More preferably, the drive assembly includes a rotating shaft with discs welded to both ends, connecting rods rotatably connected to the surfaces of the discs, a first gear welded to the middle of the rotating shaft, a second gear meshing with one side of the first gear, and an output shaft of a drive motor mounted on the bottom of the second gear.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a combined screening device, including a fixed frame 1, a screening component 2 and a guide plate 3 installed inside the fixed frame 1, and a drive component 4 installed on one side of the screening component 2.
[0024] The screening assembly 2 includes a screen frame 201, a screen plate 202 inserted inside the screen frame 201, a tension spring 203 sleeved on the outside of the screen frame 201, a slide rod 204 welded to the bottom of the screen frame 201, a ball bearing 205 embedded in the bottom of the slide rod 204, a track 206 slidably connected to the outside of the slide rod 204, bolts 207 threadedly connected to the front and back of the screen frame 201, and a side plate 208 slidably connected to the side of the screen frame 201.
[0025] In this embodiment, as Figure 2 and Figure 5 As shown, the drive assembly 4 includes a rotating shaft 401, with discs 402 welded to both ends of the rotating shaft 401. A connecting rod 403 is rotatably connected to the surface of the discs 402. A first gear 404 is welded to the middle of the rotating shaft 401. A second gear 405 meshes with one side of the first gear 404. The output shaft of the drive motor 406 is installed at the bottom of the second gear 405. It should be noted that the connecting rod 403 is located at the edge of the disc 402. The drive motor 406 drives the second gear 405 and the first gear 404 to rotate, which in turn drives the disc 402 to rotate. When the disc 402 rotates, it pulls the connecting rod 403 to slide back and forth, which in turn drives the screening assembly 2 to vibrate back and forth for screening.
[0026] In this embodiment, as Figure 1 and Figure 2As shown, there are two sets of screening components 2, which are arranged in parallel vertically. The guide plate 3 is located between the two sets of screening components 2. It should be noted that the two sets of screening components 2 are designed as independent structures to achieve multi-stage screening, which can more accurately separate particles of different sizes and make more precise distinctions between different grades of diamonds. The material screened by the first layer of screening components 2 is collected by the guide plate 3 to prevent spillage.
[0027] In this embodiment, as Figure 3 and Figure 4 As shown, the sieve plate 202 is designed as a filter screen structure, and the end of the bolt 207 is attached to the upper surface of the sieve plate 202. It should be noted that the filter hole diameter of the first layer sieve plate 202 is larger than that of the second layer sieve plate 202. Diamond raw material particles pass through sieves with different hole diameters to achieve the purpose of grading by size. There are protruding clips on the inner wall of the sieve frame 201, which can hold the lower surface of the sieve plate 202 against it. The bolt 207 is then rotated and screwed into the sieve frame 201. The end of the bolt 207 holds the upper surface of the sieve plate 202 against it, fixing the sieve plate 202 to the bottom of the sieve frame 201. Different hole diameter sieve plates 202 can also be replaced at any time.
[0028] In this embodiment, as Figure 2 As shown, the connecting rod 403 is rotatably connected to the other end of the screen frame 201. It should be noted that two connecting rods 403 are installed on the edges of the two discs 402 at the same time. The top connecting rod 403 is rotatably connected to the first-layer screen frame 201, and the bottom connecting rod 403 is connected to the second-layer screen frame 201. The two connecting rods 403 are connected by a rotating shaft 401. The two discs 402 rotate at the same time, which can complete multiple levels of screening at the same time.
[0029] In this embodiment, as Figure 1 and Figure 4 As shown, the two ends of the track 206 are welded to the inner wall of the fixed frame 1, and the ball bearings 205 are in close contact with the inner wall of the track 206. It should be noted that the track 206 and the fixed frame 1 are connected, the position of the track 206 is fixed, the slide bar 204 slides along the track 206 to control the movement path of the screen frame 201, and the ball bearings 205 at the bottom of the limiting rod can assist the screen frame 201 in sliding.
[0030] In this embodiment, as Figure 1 As shown, the vertical center line of the rotating shaft 401 is perpendicular to the horizontal center line of the disk 402. It should be noted that the disk 402 is perpendicular to the rotating shaft 401, and the rotating shaft 401 is also perpendicular to the ground. The disk 402 always remains horizontal when rotating and will not rub against the connecting rod 403.
[0031] The usage and advantages of this utility model: The working process of this combined screening device is as follows:
[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, firstly, the sieve plate 202 is installed inside the sieve frame 201. The sieve plate 202 is laid flat on the bottom of the inner wall of the sieve frame 201. The bolts 207 on both sides are rotated, and the upper surface of the sieve plate 202 is held in place by the bolts 207. The raw material to be screened is poured into the first layer of the sieve frame 201. The drive motor 406 is started. The drive motor 406 drives the second gear 405 to rotate. The second gear 405 drives the first gear 404 and the rotating shaft 401 to rotate. The rotating shaft 401 drives the discs 402 at both ends to rotate. The discs 402 pull the connecting rod 403 and the sieve frame 201 to vibrate back and forth. The sieve frame 201 performs periodic reciprocating motion in a straight line along the track 206. The material is screened. The amplitude of the vibrating screen is controlled by the tension spring 203 to prevent excessive vibration. The first screen plate 202 screens the largest particles, and the second screen plate 202 screens the slightly smaller particles. A receiving box is provided at the bottom of the second screen frame 201. The smallest particles are caught by the receiving box at the bottom. The side plate 208 can be slid open to remove the material from the two screen frames 201 respectively.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
