Description

Technical Field

[0001] This utility model relates to a drum screen, specifically an easy-to-maintain drum screen, and belongs to the field of screening machine technology. Background Technology

[0002] A drum screen is a device that uses a rotating cylindrical screen to classify and screen materials. Its core component is a cylindrical drum with screen holes. As the material rotates inside the drum, it passes through the screen holes to separate coarse and fine particles. Drum screens are widely used in mining, building materials, agriculture and other fields, and are especially suitable for classifying and removing impurities from granular, lumpy and powdery materials. The drum screen mainly consists of a drum screen body, a drive unit and a cleaning component. The cleaning component usually drives the beaters to beat the outer wall of the drum screen body or the screening rod by rotating the rod connected to the mounting frame, causing the material blocked in the screen holes to fall off, thereby effectively preventing the screen holes from clogging.

[0003] However, the beaters of traditional drum screens are usually directly fixed to the rotating rod with bolts. Bolting makes it inconvenient to adjust the position of the beaters, making it difficult to flexibly adjust the clearing layout according to material characteristics, blockage areas, and other working conditions. Furthermore, since the beaters need to continuously impact the screen body to clear blockages during screening, they are subjected to high-frequency impacts and friction over a long period of time, resulting in severe wear and structural fatigue. Therefore, the beaters need to be replaced. However, disassembly and assembly require the use of wrenches and other tools to loosen and loosen the bolts one by one, which is cumbersome and time-consuming, significantly extending downtime for maintenance. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-maintain drum screen to solve the above-mentioned problems. The installation base, positioning rod and positioning sleeve can be used to quickly install and adjust the position of the beat bars. It is easy to operate, can quickly respond to changes in working conditions, and greatly improves the efficiency of beat bar replacement and maintenance. Furthermore, the protrusion and positioning sleeve make it impossible for the installation base and beat bars to move, thereby improving the stability of beat bar installation.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 As shown, an easy-to-maintain drum screen includes a mounting frame 1, a rotating shaft 2 rotatably connected to the mounting frame 1, a screen body 3 fixedly connected to the rotating shaft 2, a cleaning component 4 mounted on the mounting frame 1, and the cleaning component 4 including a rotating rod 401 rotatably connected to the mounting frame 1. Multiple beaters 402 are mounted on the rotating rod 401 via a fixing component 5. The fixing component 5 includes a sliding groove 501, and the rotating rod 401 has a sliding groove 501 within which it slides. Multiple mounting bases 502 are connected, and a positioning rod 503 is fixedly connected to the bottom end of each mounting base 502. A positioning sleeve 504 is installed on the top end of the tapping bar 402. The positioning rod 503 is inserted into the positioning sleeve 504. A knob 505 is rotatably connected to the positioning sleeve 504. The knob 505 is rotatably connected to the tapping bar 402. The end of the knob 505 is threadedly connected to the positioning rod 503. A protrusion 506 is fixedly connected to the rotating rod 401. The positioning sleeve 504 abuts against the protrusion 506.

[0023] As a technical optimization of this utility model, the end section of the mounting base 502 is T-shaped, and the overall structure of the mounting base 502 is L-shaped, which increases the stability of the mounting base 502 and prevents the mounting base 502 from slipping out of the slide groove 501. This allows the beating bar 402 to fit the curved surface of the screen body 3, thereby increasing the beating area and uniform force of the beating bar 402 on the screen body 3. The cross section of the positioning rod 503 is rectangular, which can prevent the positioning sleeve 504 from driving the beating bar 402 to rotate, thus ensuring the stable installation of the beating bar 402. The positioning sleeve 504 is T-shaped, which facilitates the contact and limiting of the positioning sleeve 504 and the protrusion 506, further improving the stability of the installation of the beating bar 402.

[0024] As a technical optimization of this utility model, the rotating rod 401 is provided with a slot 507, which is connected to the sliding groove 501, so that the mounting base 502 can slide into the sliding groove 501 from the slot 507, thereby simplifying the installation path of the mounting base 502 and making the installation and disassembly of the mounting base 502 more convenient.

[0025] As a technical optimization of this utility model, a brush shaft 409 is rotatably connected to the mounting frame 1, and a cleaning brush 403 is fixedly connected to the brush shaft 409. The cleaning brush 403 and the beating bar 402 form a dual cleaning mode of "sweeping + beating". The beating bar 402 shakes off the material clogging the screen holes, and the cleaning brush 403 sweeps away the residue on the surface of the screen body 3. The two work together to achieve all-round cleaning of the screen body 3, effectively reducing screen hole clogging and improving the cleaning effect and working stability of the screening machine. A first motor 404 is installed on the mounting frame 1, and the output of the first motor 404... A first pulley 405 is fixedly connected to both the shaft and the brush shaft 409. The same first belt 406 is wound around the outside of the two first pulleys 405. A second pulley 407 is fixedly connected to both the brush shaft 409 and the rotating rod 401. The same second belt 408 is wound around the outside of the two second pulleys 407. The first motor 404 cooperates with the brush shaft 409, the first pulley 405, the first belt 406, the rotating rod 401, the second pulley 407, and the second belt 408 to provide power for the rotation of the tapping strip 402 and the cleaning brush 403.

[0026] As a technical optimization of this utility model, a second motor 6 is installed on the mounting frame 1. A third pulley 7 is fixedly connected to both the output shaft and the rotating shaft 2 of the second motor 6. The same third belt 8 is wound around the outside of the two third pulleys 7. The second motor 6 transmits power to the rotating shaft 2 through the third pulleys 7 and the third belt 8, so that the rotating shaft 2 drives the screen body 3 to rotate, thereby realizing material screening. One end of the mounting frame 1 is provided with a feed inlet 9, the other end of the mounting frame 1 is provided with a coarse material outlet 10, and the side of the mounting frame 1 is provided with a fine material outlet 11. The setting of the feed inlet 9, the coarse material outlet 10 and the fine material outlet 11 respectively realizes the material entering the screening machine, the coarse particles being discharged after screening, and the fine particles being discharged, thereby forming a complete material screening and conveying path.

[0027] In use, when installing the tapping bar 402, first push the mounting base 502 into the slide groove 501 from the slot 507, and then slide it along the slide groove 501 to the target position. Next, insert the knob 505 into the mounting hole on the positioning sleeve 504, so that the knob 505 passes through the mounting hole on the positioning sleeve 504 and the tapping bar 402. Then, align the positioning sleeve 504 with the positioning rod 503 at the bottom of the mounting base 502, and then move the positioning sleeve 504 so that the positioning sleeve 504 and the positioning rod 503 are inserted. Then, gradually tighten the knob 505 so that the end of the knob 505 is threaded with the positioning rod 503. The knob 505 connects the positioning sleeve 504 to the protruding strip 506, further securing the beater bar 402 and the mounting base 502 through the contact between the positioning sleeve 504 and the protruding strip 506. This prevents the mounting base 502 from sliding within the groove 501 and causing the beater bar 402 to shift, thus quickly and securely installing the beater bar 402. This improves the efficiency of replacing and maintaining the beater bar 402. Furthermore, the sliding fit between the mounting base 502 and the groove 501 allows for flexible adjustment of the beater bar 402's installation position according to actual working conditions, enhancing the flexibility of the beater bar 402's use and optimizing the screen's performance. The cleaning efficiency of body 3; when screening of materials is required, the second motor 6 is started. The second motor 6 drives the rotating shaft 2 to rotate through the third pulley 7 and the third belt 8. The rotation of the rotating shaft 2 simultaneously drives the screen body 3 to rotate around the rotating shaft 2, thereby realizing material screening. When the screen body 3 rotates, the material enters from the feed inlet 9. Fine particles fall through the screen holes to the bottom of the screen body 3 and are discharged from the fine material outlet 11 on the side of the mounting frame 1 along the guide plate on the mounting frame 1, while coarse particles move axially along the screen body 3 to the coarse material outlet 10 for discharge; then the first motor 404 is started, the first motor 404 drives the first... The pulley 405 and the first belt 406 drive the brush shaft 409 to rotate. The rotation of the brush shaft 409 simultaneously drives the cleaning brush 403 to rotate, thereby cleaning the screen holes of the screen body 3. At the same time, the brush shaft 409 drives the rotating rod 401 to rotate synchronously through the second pulley 407 and the second belt 408, causing the beating bar 402 to rotate with the rotating rod 401 and periodically beat the screen body 3, thereby shaking off the material blocking the screen holes. Thus, the cooperation between the beating bar 402 and the cleaning brush 403 achieves efficient cleaning of the screen body 3, effectively preventing the screen body 3 from clogging, thereby improving the screening effect of the screening machine.
