Description

Technical Field

[0001] This utility model belongs to the field of drum screen technology, and more specifically, it relates to a drum screen for finished particles. Background Technology

[0002] A finished particle drum screen is a mechanical device used for screening finished granular materials. It mainly consists of a drum, frame, and drive unit. The drum is usually placed at an angle and its surface is covered with screen holes. During operation, the material enters from one end of the drum. Under the rotation of the drum, smaller particles can fall through the screen holes, while larger particles are discharged from the other end along the inclined direction of the drum. Finished particle drum screens have high screening efficiency and can quickly separate finished particles of different sizes. They have a large processing capacity, are suitable for large-scale production needs, have a simple structure, are relatively easy to operate and maintain, and have wide applicability. They can be used for various types of finished granular materials. They play a very important role in industrial production, effectively improving product quality and ensuring the continuity and stability of production.

[0003] While existing finished particle drum screens can separate materials of different particle sizes during use, the material is continuously fed into the drum screen. The inclination and rotation speed of the drum screen determine the flow rate of the material from the feed end to the discharge end. Currently, the inclination angle of the finished particle drum screen is fixed. When the continuous input of material is large, the drum screen needs to increase the rotation speed to increase the centrifugal force of the material within it in order to achieve the ideal screening effect. However, while the rotation speed increases, the material flow rate within the drum screen also increases relatively. This may cause smaller particles to be quickly carried out before they can pass through the screen holes, thereby reducing the screening accuracy and efficiency. Increasing the rotation speed may make it easier for some particles stuck in the screen holes to pass through, but it may also cause smaller particles to be thrown up and have difficulty passing through the screen holes, affecting the screening accuracy.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a finished particle drum screen in order to achieve a more practical value. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a finished particle drum screen.

[0006] The purpose and effect of this utility model of a finished particle drum screen are achieved by the following specific technical means:

[0007] A finished particle drum screen includes a drum screen with multiple sections of screens with different aperture sizes. A drum screen drive assembly is installed at the bottom of the drum screen. A base assembly is provided on the bottom surface of the drum screen drive assembly. An angle adjustment assembly for use with the drum screen drive assembly is installed on the base assembly. A conveying assembly is installed at the bottom of the base assembly.

[0008] Furthermore, the drum screen drive assembly includes a drive base, on the top of which several sets of rotating wheels for use with the drum screen are symmetrically installed. Two drive motors are installed on the top surface of the drive base at the discharge end of the drum screen, and the rotating ends of the two drive motors are respectively fixedly connected to the rotating wheels on the same side.

[0009] Furthermore, the base assembly includes a rectangular frame base disposed directly below the drive base, with support legs evenly distributed on the bottom surface of the rectangular frame base, and cross-shaped sliding grooves opened in the middle of the front and rear sides of the rectangular frame base.

[0010] Furthermore, the angle adjustment assembly includes two hinge joints and two hinge slot blocks 2 symmetrically installed at the bottom of the drive base. The hinge joints are located on the discharge end side of the drum screen, and the two hinge slot blocks 2 are located on the feed end side of the drum screen. Adjustment rods are rotatably installed on both of the two hinge slot blocks 2.

[0011] Furthermore, the angle adjustment assembly also includes a T-shaped slider slidably disposed in the middle of the cross-shaped groove and two hinged slot blocks symmetrically installed on the top right side of the rectangular frame base. The two hinged slot blocks are rotatably connected to the hinge joints on the same side. The T-shaped slider is rotatably connected to the other end of the adjustment rod on the same side. A hydraulic telescopic rod is fixedly installed in the middle of the right side wall of the inner cavity of the cross-shaped groove. The telescopic end of the hydraulic telescopic rod is fixedly connected to the middle of the right side wall of the T-shaped slider.

[0012] Furthermore, the conveying assembly includes several hoppers fixedly installed in the middle of the bottom surface of the drive base and several conveyor belt mechanisms set on the bottom surface of the rectangular frame base. The number of conveyor belt mechanisms and hoppers is matched with the number of screens.

[0013] Furthermore, a connecting seat is fixedly installed between the adjacent conveyor belt mechanisms, and a connecting rod is symmetrically installed on the top surface of the connecting seat in the middle. The upper ends of the two connecting rods are respectively fixedly connected to the middle of the bottom surface of the T-shaped slider on the same side.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When a large amount of material is continuously fed in, this utility model uses the retraction of the hydraulic telescopic rod to drive the T-shaped slider to slide towards the discharge end of the drum screen. The adjustment rod between the hinged groove block two at the bottom of the drive base and the T-shaped slider changes its tilt angle as the T-shaped slider moves, thereby reducing the height of the discharge end of the drive base and decreasing the overall tilt angle of the drum screen. This slows down the flow rate of the material from the feed end to the discharge end of the drum screen. By increasing the rotation speed of the drive motor, the material flow rate is restored to a normal level, thus ensuring the screening accuracy. Conversely, the tilt angle of the drum screen can be increased by the angle adjustment component, reducing the rotation speed of the drive motor to screen the material, thereby reducing the workload of the drive motor.

[0016] 2. When the tilt angle of the drive base and the drum screen on it is adjusted, the positions of the discharge ports of several hoppers at the bottom of the drive base will also change accordingly. The T-shaped slider slides and drives the connecting rod at the bottom to slide. Since the connecting rod is fixedly connected to the connecting seat in the middle of several conveyor belt mechanisms, the positions of several conveyor belt mechanisms change simultaneously, and thus match the positions of the discharge ports of the hoppers. The material falling from the discharge ports of the hoppers can accurately fall on the matching conveyor belt mechanism. In this way, while adjusting the tilt angle of the drum screen, it ensures that the material is accurately separated and transported and collected after screening, which is more conducive to the gradation screening of materials.

[0030] Example:

[0031] As attached Figure 1 To be continued Figure 4 As shown: A finished particle drum screen includes a drum screen 1 with multiple sections of screens with different aperture sizes. A drum screen drive assembly 2 is installed at the bottom of the drum screen 1. A base assembly 3 is provided on the bottom surface of the drum screen drive assembly 2. An angle adjustment assembly 4 for use with the drum screen drive assembly 2 is installed on the base assembly 3. A conveying assembly 5 is installed at the bottom of the base assembly 3.

[0032] The drum screen drive assembly 2 includes a drive base 201. Several sets of rotating wheels 202 for use with the drum screen 1 are symmetrically installed on the top front and back of the drive base 201. Two drive motors 203 are installed on the top surface of the drive base 201 at the discharge end of the drum screen 1. The rotating ends of the two drive motors 203 are respectively fixedly connected to the rotating wheels 202 on the same side.

[0033] The base assembly 3 includes a rectangular frame base 301 located directly below the drive base 201. Support legs 302 are evenly distributed on the bottom surface of the rectangular frame base 301, and cross-shaped grooves 303 are provided in the middle of the front and rear sides of the rectangular frame base 301.

[0034] The angle adjustment assembly 4 includes two hinge joints 401 and a hinge slot block 403 installed symmetrically at the bottom of the drive base 201. The hinge joints 401 are located on the discharge end side of the drum screen 1, and the hinge slot block 403 is located on the feed end side of the drum screen 1. An adjustment rod 404 is rotatably installed on both hinge slot blocks 403.

[0035] The angle adjustment assembly 4 also includes a T-shaped slider 405 slidably disposed in the middle of the cross-shaped slide groove 303 and two hinged slot blocks 402 symmetrically installed on the top right side of the rectangular frame base 301. The two hinged slot blocks 402 are rotatably connected to the hinge joint 401 on the same side. The T-shaped slider 405 is rotatably connected to the other end of the adjustment rod 404 on the same side. A hydraulic telescopic rod 406 is fixedly installed in the middle of the right side wall of the inner cavity of the cross-shaped slide groove 303. The telescopic end of the hydraulic telescopic rod 406 is fixedly connected to the middle of the right side wall of the T-shaped slider 405.

[0036] Above, the hydraulic telescopic rod 406 retracts, causing the T-shaped slider 405 to slide towards the discharge end of the drum screen 1. The adjusting rod 404 between the hinged groove block 403 at the bottom of the drive base 201 and the T-shaped slider 405 changes its tilt angle as the T-shaped slider 405 moves, thereby reducing the height of the discharge end of the drive base 201 and thus reducing the overall tilt angle of the drum screen 1. At this time, the flow speed of the material from the feed end to the discharge end of the drum screen 1 slows down. Then, by increasing the rotation speed of the drive motor 203, the material flow rate is driven back to a normal level.

[0037] As attached Figure 1 To be continued Figure 4 As shown, in some embodiments, the conveying assembly 5 includes a plurality of hoppers 504 fixedly installed in the middle of the bottom surface of the drive base 201 and a plurality of conveyor belt mechanisms 503 disposed on the bottom surface of the rectangular frame base 301. The number of conveyor belt mechanisms 503 and hoppers 504 is matched with the number of screens.

[0038] As attached Figure 1 To be continued Figure 4As shown, in some embodiments, a connecting seat 502 is fixedly installed between adjacent conveyor belt mechanisms 503, and a connecting rod 501 is symmetrically installed on the top surface of the connecting seat 502 in the middle. The upper ends of the two connecting rods 501 are respectively fixedly connected to the middle of the bottom surface of the T-shaped slider 405 on the same side.

[0039] When the tilt angle of the drive base 201 and the drum screen 1 on it is adjusted, the position of the discharge port of several hoppers 504 at the bottom of the drive base 201 will also change accordingly. The T-shaped slider 405 slides and drives the connecting rod 501 at the bottom to slide. Since the connecting rod 501 is fixedly connected to the connecting seat 502 in the middle of several conveyor belt mechanisms 503, the positions of several conveyor belt mechanisms 503 will change simultaneously, and thus match the position of the discharge port of the hopper 504. This allows the material falling from the discharge port of the hopper 504 to accurately fall on the matching conveyor belt mechanism 503, thereby ensuring that the material is accurately separated and transported and collected after screening while the tilt angle of the drum screen 1 is adjusted.

[0040] The specific usage and function of this embodiment are as follows: When the continuous input of material is large, the hydraulic telescopic rod 406 retracts, driving the T-shaped slider 405 to slide towards the discharge end of the drum screen 1. The adjustment rod 404 between the hinged groove block 403 at the bottom of the drive base 201 and the T-shaped slider 405 changes its tilt angle as the T-shaped slider 405 moves, thereby reducing the height of the discharge end of the drive base 201 and thus reducing the overall tilt angle of the drum screen 1. At this time, the flow speed of the material from the feed end to the discharge end of the drum screen 1 slows down. At this time, by increasing the rotation speed of the drive motor 203, the material flow rate is driven back to a normal level, thereby ensuring the screening accuracy. Conversely, when the continuous input of material is small, the tilt angle of the drum screen 1 can be increased by the angle adjustment component 4, reducing the rotation speed of the drive motor 203 to screen the material, thereby reducing the workload of the drive motor 203.

Many modifications and variations will be apparent to those skilled in the art.
