Description

Technical Field

[0001] This utility model relates to the field of material feeding device technology, specifically an automatic material feeding device for a mineral processing plant. Background Technology

[0002] The structure of an automated material distribution system in a mineral processing plant typically includes a feeding unit, a discharging unit, a material distribution unit, a drive unit, and a detection and positioning unit. These parts work together to achieve automated material distribution. As part of the feeding unit, the conveyor belt transports the ore to the material distribution trolley.

[0003] However, during the use of automatic feeding devices in mineral processing plants, when the material has a high moisture content or a fine particle size, the powder particles adhering to the surface of the conveyor belt can cause uneven material distribution during the feeding process. The adhering material may change the actual operating parameters of the conveyor belt, such as thickness and friction, thereby affecting the measurement and control accuracy of the feeding system. At the same time, it will also increase the running resistance, requiring the drive motor to consume more energy to maintain the normal operation of the conveyor belt.

[0004] To ensure equipment safety, it may be necessary to reduce the operating speed of the conveyor belt, thereby reducing the overall production efficiency of the production line. Excessive powder or particulate material may cause conveyor belt misalignment, slippage, and other malfunctions. Therefore, the conveyor belt needs to be cleaned during and after operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic material feeding device for mineral processing plants, which can clean the conveyor belt.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic material distribution device for a mine, comprising a running track, on which a material distribution trolley is installed, and a conveyor belt is connected to both the running track and the material distribution trolley. Two cylinders are fixedly connected to the running track, and rotating blocks are fixedly connected to the two cylinders. An upper driver is fixedly connected to the rotating blocks, and the output end of the driver is fixedly connected to a connecting rod. The connecting rod is rotatably connected to the rotating blocks, and a roller brush is installed on the connecting rod.

[0007] Furthermore, two slots are provided on the running track, and an interception mechanism is detachably connected to each slot. The interception mechanism includes an L-shaped insert plate that matches the slot. The front ends of the two L-shaped insert plates are connected to an inclined baffle. Tightening bolts for fixing the L-shaped insert plates are threaded onto the running track.

[0008] Furthermore, the driver is a variable frequency speed control motor or a continuously variable speed motor, and the driver is electrically connected to the controller of the automatic fabric feeding device.

[0009] Furthermore, the connecting rod has several insertion holes, and the roller brush is composed of four identical parts. The four parts are fixed by a fixing assembly. Each part includes an arc-shaped plate, and two limiting plates are fixedly connected to both ends of the arc-shaped plate. A cleaning brush is fixedly connected to the outer surface of the arc-shaped plate, and an insertion rod that matches the insertion hole is fixedly connected to the inner surface of the arc-shaped plate.

[0010] Furthermore, the fixing assembly includes two semicircular plates placed between two limiting plates, with extrusion plates fixedly connected to both ends of the two semicircular plates. The extrusion plates have circular holes, and the two extrusion plates are connected by bolts and nuts.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This type of automatic material feeding device for mineral processing plants can clean the powder and particulate materials adhering to the surface of the conveyor belt through a roller brush, avoiding the negative impact of excessive powder and particulate materials. The roller brush consists of four parts, which are easy to install and disassemble. Similarly, when one part is severely worn and affects the cleaning effect, it can be replaced individually without replacing the whole part, which can effectively reduce the waste of resources.

[0017] 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.

[0018] Please see Figures 1 to 3An automatic material distribution device for a mineral processing plant includes a running track 1, a material distribution trolley 2 mounted on the running track 1, a conveyor belt 3 connected to both the running track 1 and the material distribution trolley 2, two cylinders 18 fixedly connected to the running track 1, a rotating block 19 fixedly connected to the two cylinders 18, an upper driver 4 fixedly connected to the rotating block 19, the output end of the driver 4 fixedly connected to a connecting rod 5, the connecting rod 5 rotatably connected to the rotating block 19, and a roller brush 6 mounted on the connecting rod 5.

[0019] like Figures 1 to 3 As shown, in the automatic material feeding device of the ore dressing plant of this utility model, the material is transported from the conveyor belt 3 to the inside of the feeding trolley 2. Under the control of the controller in the automatic feeding device, the material can be automatically fed. During the operation of the conveyor belt 3, the driver 4 is started, which causes the connecting rod 5 to rotate, thereby causing the roller brush 6 to rotate in the opposite direction to the running direction of the conveyor belt 3. The roller brush 6 cleans the particles adhering to the surface of the conveyor belt 3, thereby avoiding the negative impact of too many particles on the automatic feeding device. After cleaning is completed, the roller brush 6 can be moved downward by two cylinders 18 to avoid continuous cleaning and wear on the conveyor belt 3.

[0020] like Figure 2 or Figure 3 As shown, the running track 1 has two slots 7, and an interception mechanism is detachably connected to the two slots 7. The interception mechanism includes an L-shaped insert plate 8 that matches the slot 7. The front ends of the two L-shaped insert plates 8 are connected to an inclined baffle 9. The running track 1 is threaded with a tightening bolt 10 for fixing the L-shaped insert plates 8.

[0021] Specifically, the inclined baffle 9 can intercept the particulate material cleaned by the roller brush 6, preventing the particulate material from splashing everywhere. At the same time, the baffle 9 can be quickly removed by contacting the tightening bolt 10 to fix the L-shaped insert plate 8.

[0022] like Figure 1 As shown, the driver 4 is a variable frequency speed control motor or a continuously variable speed motor, and the driver 4 is electrically connected to the controller of the automatic fabric feeding device.

[0023] Specifically, the controller of the automatic fabric feeding device can control the driver 4 so that the roller brush 6 moves along with the conveyor belt 3 when the conveyor belt 3 is running. When the conveyor belt 3 is not running, the driver 4 stops running to prevent the roller brush 6 from continuously rubbing against a part of the conveyor belt 3 and causing wear.

[0024] like Figure 2As shown, the connecting rod 5 has several insertion holes 11. The roller brush 6 is composed of four identical parts, which are fixed by a fixing assembly. Each part includes an arc plate 12. Two limiting plates 13 are fixedly connected to both ends of the arc plate 12. A cleaning brush 14 is fixedly connected to the outer surface of the arc plate 12, and an insertion rod 15 that matches the insertion hole 11 is fixedly connected to the inner surface of the arc plate 12.

[0025] Specifically, the insertion hole 11 is used to initially fix the four components of the roller brush 6. The insertion rod 15 on the inner surface of the arc plate 12 is inserted into the insertion hole 11. The arc plate 12 is installed and fixed in the same way. The two limiting plates 13 are used to limit the fixing components.

[0026] like Figure 3 As shown, the fixing assembly includes two semi-circular plates 16 placed between two limiting plates 13. Both ends of the two semi-circular plates 16 are fixedly connected to extrusion plates 17. The extrusion plates 17 have circular holes. The two extrusion plates 17 are connected by bolts and nuts.

[0027] Specifically, after connecting the four parts of the roller brush 6 to the insertion hole 11, place the two semi-circular plates 16 between the two limiting plates 13, insert the bolts into the round holes on the extrusion plate 17, and then connect the nuts and bolts to fix the two extrusion plates 17 together, thereby fixing the two semi-circular plates 16 together, and so on, to fix the four parts of the roller brush 6 together.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
