Description

Technical Field

[0001] This utility model relates to the field of material separation technology, and in particular to a drum screener. Background Technology

[0002] The main function of a drum screen is to separate granular materials into different grades according to particle size. The drum screen utilizes the relative movement between the granular material and the screen surface, allowing some particles to pass through the screen holes, thus separating materials such as sand, gravel, and crushed stone into different size grades. Drum screens are widely used in the chemical, building materials, food processing, mining, and pharmaceutical industries.

[0003] A search revealed Chinese Patent Publication No. CN214718182U, which discloses a mobile crushed stone screening mechanism to prevent material blockage. This utility model's crushed stone screening drum includes a front screening cylinder, a middle screening cylinder, and a rear screening cylinder, all with metal screens on their outer surfaces. The metal screens are connected to the front, middle, and rear screening cylinders by screws. The screen gap in the front screening cylinder is larger than that in the middle screening cylinder, and the screen gap in the middle screening cylinder is larger than that in the rear screening cylinder. Larger stones, after entering the crushed stone screening drum, fall from the front screening cylinder into the corresponding screening hopper. The stones remaining inside the crushed stone screening drum continue to be filtered through the middle and rear screening cylinders, thus preventing the stones from clogging the screen.

[0004] However, the aforementioned rotary drum screener still has some shortcomings: its multiple screening drums have the same diameter and their placement is fixed, meaning they can only be arranged in a straight line, resulting in a large device size. When not in use or being transported, the fixed positions of the screening drums prevent them from being extended or folded up, further increasing the device's footprint, reducing space utilization, and making it inconvenient to use. Therefore, it is necessary to design a rotary drum screener that is easy to unfold and fold up to reduce its footprint when not in use or being transported, thereby improving space utilization. Utility Model Content

[0005] In order to overcome the limitations of existing screening machines where multiple screening drums have the same diameter and are placed in a fixed position, thus requiring them to be arranged in a straight line, resulting in a large device size, and the inability to extend or retract the drums when not in use or during transport, thereby increasing the footprint and reducing space utilization, one of the objectives of this utility model is to provide a drum screening machine.

[0006] One of the objectives of this utility model is achieved through the following technical solution: A drum screening machine, comprising an adjustable support mechanism and a drum screening mechanism: the drum screening mechanism is disposed above the adjustable support mechanism, the adjustable support mechanism includes a support frame one, a sliding groove symmetrically fixedly connected to one side of the support frame one, a sliding rod slidably connected to the inner wall of the sliding groove, a support frame two fixedly connected to one side of the sliding rod, a threaded hole one is opened on the upper surface of the sliding groove near the support frame two, and threaded holes two are symmetrically opened on the upper surface of the sliding rod, a limiting rod one is threadedly connected to the inner wall of the threaded hole one, and the limiting rod one is connected to the threaded hole two. Hole 2 is threaded. A rotating sleeve is fixedly connected to one side of the support frame 1. The drum screening mechanism includes a drum screen 1 rotatably connected to the inner wall of the rotating sleeve. A drum screen 2 is slidably connected to the inner wall of the drum screen 1. Slide rails are fixedly connected to the middle of the upper and lower surfaces of the drum screen 1. A sliding member is slidably connected to the inner wall of the slide rail. The sliding member is fixedly connected to the drum screen 2. A threaded hole 3 is opened on the upper surface of one side of the slide rail. Threaded holes 4 are symmetrically opened on the inner bottom wall of the sliding member. A limit rod 2 is threadedly connected to the inner wall of the threaded hole 3. The limit rod 2 is threadedly connected to the threaded hole 4. This design facilitates the storage and deployment of the device. When material screening is not required, the drum screen 2 can be stored inside the drum screen 1, and the adjustable support mechanism can be retracted, thereby reducing the footprint of the device and improving space utilization.

[0007] According to the drum screening machine, a knob is fixedly connected to one side of both the first limiting rod and the second limiting rod. This facilitates the rotation of the first limiting rod and the second limiting rod.

[0008] According to the aforementioned drum screen, a fixed frame is fixedly connected to one side of the support frame one. A servo motor is fixedly connected to the inner wall of one side of the fixed frame. A rotating shaft is fixedly connected to the output end of the servo motor. The rotating shaft passes through one side wall of the fixed frame and is rotatably connected to the fixed frame. A drive gear is fixedly connected to the outer surface of the rotating shaft. A driven gear is meshed with one side of the drive gear. The driven gear is fixedly connected to the drum screen one. This facilitates driving the drum screen one and drum screen two to rotate for material screening.

[0009] According to the aforementioned drum screening machine, the inner wall of the rotating sleeve is provided with a rotating groove, and a limiting ring is rotatably connected to the inner wall of the rotating groove. The limiting ring is fixedly connected to one outer surface of the drum screen one. This facilitates the improvement of the rotational stability of drum screen one and drum screen two.

[0010] According to the aforementioned drum screening machine, a first collection trough and a second collection trough are respectively placed on the upper surfaces of the first support frame and the second support frame. This facilitates the classification and collection of the screened materials.

[0011] According to the described rotary drum screen, the size of the second receiving trough is smaller than the size of the first receiving trough. This facilitates the storage of the second receiving trough inside the first receiving trough.

[0012] According to the aforementioned rotary drum screen, the diameter of the screen holes on the outer surface of one rotary drum screen is larger than the diameter of the screen holes on the outer surface of the other rotary drum screen. This facilitates the screening of materials.

[0013] According to the aforementioned drum screening machine, anti-slip pads are fixedly connected to the lower surfaces of both support frame one and support frame two. This increases the friction between support frame one and support frame two and the surface, thereby improving the stability of the device.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] By incorporating an adjustable support mechanism and a drum screening mechanism, this device, compared to existing technologies, can achieve the storage and unfolding of the drum screen two through the cooperation of the adjustable support mechanism and the drum screening mechanism. Furthermore, the adjustable support mechanism can extend and retract, facilitating the placement of the receiving trough two and the receiving trough one for material collection. This reduces the footprint of the device when not in use, effectively improving space utilization and thus enhancing the practicality, flexibility, and convenience of the device.

[0028] The rotary drum screening mechanism 2 includes a rotary drum screen 201 rotatably connected to the inner wall of the rotating sleeve 14. A rotary drum screen 202 is slidably connected to the inner wall of the rotary drum screen 201. Slide rails 203 are fixedly connected to the middle of the upper and lower surfaces of the rotary drum screen 201. Sliding parts 204 are slidably connected to the inner wall of the slide rails 203. The sliding parts 204 are fixedly connected to the rotary drum screen 202. A threaded hole 205 is opened on one side of the upper surface of the slide rails 203. Threaded holes 206 are symmetrically opened on the inner bottom wall of the sliding parts 204. A limit rod 207 is threadedly connected to the inner wall of the threaded hole 205. The limit rod 207 is threadedly connected to the threaded hole 206. A knob 3 is fixedly connected to one side of both the limit rod 107 and the limit rod 207.

The output end of the servo motor 5 is fixedly connected to the inner wall of the support frame 101. A rotating shaft 6 is fixedly connected to the fixed frame 4. The rotating shaft 6 passes through one side wall of the fixed frame 4 and is rotatably connected to the fixed frame 4. A driving gear 7 is fixedly connected to the outer surface of the rotating shaft 6. A driven gear 8 is meshed with one side of the driving gear 7. The driven gear 8 is fixedly connected to the drum screen 201. A rotating groove 9 is opened on the inner wall of the rotating sleeve 14. A limiting ring 10 is rotatably connected to the inner wall of the rotating groove 9. The limiting ring 10 is fixedly connected to one side of the outer surface of the drum screen 201. A receiving trough 11 and a receiving trough 2 12 are respectively placed on the upper surfaces of the support frame 101 and the support frame 2 104. The size of the receiving trough 2 12 is smaller than the size of the receiving trough 11. The diameter of the screen hole on the outer surface of the drum screen 201 is larger than the diameter of the screen hole on the outer surface of the drum screen 2 202. Anti-slip pads 13 are fixedly connected to the lower surfaces of the support frame 101 and the support frame 2 104.

[0029] The servo motor 5 is powered by an external power source. The adjustable support mechanism 1 and the drum screening mechanism 2 facilitate the unfolding and storage of the device, thereby reducing the footprint of the device, improving space utilization, and making it easy to use. This effectively enhances the adjustability and convenience of the device, and facilitates transportation. The second receiving trough 12 is smaller than the first receiving trough 11, which also makes it easy to place the second receiving trough 12 inside the first receiving trough 11 for storage, making it convenient to use.

[0030] Working principle: When the device is needed for material screening, first adjust the adjustable support mechanism 1. Rotate the knob 3 to drive the limiting rod 107 to rotate upwards on the inner wall of the threaded hole 106 and the threaded hole 105, so that it is no longer in the position of limiting the sliding rod 103. Pull the support frame 104 to drive the sliding rod 103 to slide outwards on the inner wall of the slide groove 102. When the sliding rod 103 can no longer slide, it means that the threaded hole 106 on one side of the upper surface of the sliding rod 103 is aligned with the threaded hole 105. Rotate the knob 3 in the opposite direction to drive the limiting rod 107 to move downwards on the inner wall of the threaded hole 105 and pass through the threaded hole 106, thereby limiting the sliding rod 103 in the slide groove 102, so that the adjustable support mechanism 1 can be unfolded and used.

[0031] Next, remove the second drum screen 202 from the inner wall of the first drum screen 201 for use. Turn the knob 3 to move the second limiting rod 207 upward from the inner wall of the fourth threaded hole 206 and the third threaded hole 205, away from the position of the limiting sliding member 204. Pull the second drum screen 202 to move the two sliding members 204 outward from the inner wall of the two slide rails 203. When the fourth threaded hole 206 on the other side of the sliding member 204 is aligned with the third threaded hole 205, screw the second limiting rod 207 into the inner wall of the third threaded hole 205 and the fourth threaded hole 206 to limit the position of the sliding member 204, thereby removing the second drum screen 202 from the inner wall of the first drum screen 201 for use.

[0032] Finally, the receiving trough 212 is removed from the inner wall of the receiving trough 11, and the receiving trough 212 and the receiving trough 11 are placed on the support frame 2104 and the support frame 111 respectively. The drive servo motor 5 drives the drive gear 7 to rotate through the rotating shaft 6. The drive gear 7 meshes with the driven gear 8 and drives the driven gear 8 to rotate. The driven gear 8 rotates and drives the drum screen 201 to rotate, and also drives the limiting ring 10 to rotate on the inner wall of the rotating groove 9 to prevent the drum screen 201 from rotating. As the material falls off, the rotating drum screen 201 drives the rotating drum screen 202 to rotate. The material is then introduced from the opening of the drum screen 201. The drum screen 201 and the drum screen 202 have a certain inclination, so the material rotates on the inner wall of the drum screen 201 and the drum screen 202 and is screened into the corresponding collection trough 11 and collection trough 22 for collection. This makes it easy to use and store the drum screen 202, reduces the floor space occupied by the device, and is convenient to use.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
