Technical Field

[0001] This utility model relates to the technical field of ore feeding equipment, and in particular to an automatic feeding device for phosphate rock hoppers. Background Technology

[0002] In the phosphate rock processing process, crushed phosphate ore is typically conveyed to hoppers via belt conveyors before being loaded onto trucks. Because it's impossible to guarantee that all phosphate ore particles meet the required size during processing, some larger particles will always be present. If these larger ore blocks clog the feed inlet, manual intervention is necessary. The industry practice is to manually clear the hopper feed inlet using steel bars, which is time-consuming and labor-intensive, disrupting normal production and increasing the risk of safety accidents during the process.

[0021] like Figure 1-3As shown, in order to avoid blockage of the feed pipe 2 of the hopper 1, this utility model provides an automatic feed device for phosphate rock hopper, including hopper 1, feed pipe 2 connected to one side of the bottom of hopper 1 and vibrator 3 installed at the bottom of hopper 1. A chisel 4 is slidably arranged in the feed pipe 2 along the axial direction. A drive assembly for driving the chisel 4 to move is arranged in the extension direction of the output end of feed pipe 2. A guide structure for the chisel 4 is arranged in the feed pipe 2.

[0022] The vibrator 3 causes the conical structure at the bottom of the hopper 1 to vibrate, which assists in the feeding of the material through the feeding pipe 2. During the feeding process, the drive assembly drives the chisel 4 to move back and forth along the axial direction of the feeding pipe 2. The chisel 4 moves continuously at the input end of the feeding pipe 2, constantly agitating the material at the input end of the feeding pipe 2, thereby preventing blockage at the input end of the feeding pipe 2.

[0023] like Figure 1 and Figure 2 As shown. The drive assembly includes a mounting base 5 fixedly disposed on one side of the hopper 1. A cam 7 is horizontally rotatably arranged on the mounting base 5. The bottom end of the chisel 4 abuts against the edge of the cam 7. A rotation drive component for the cam 7 is mounted on the mounting base 5. The drive motor 13 is installed through the mounting base 5. The drive motor 13 drives the cam 7 to rotate. The bottom end of the chisel 4 abuts against the outer wall of the cam 7. Through the continuous rotation of the cam 7, the chisel 4 is pushed upward, or the chisel 4 automatically slides downward under the action of gravity after losing the push of the cam 7, thereby realizing the reciprocating movement of the chisel 4 along the axial direction of the feed pipe 2.

[0024] like Figure 1 and Figure 2 As shown, to reduce friction between the bottom end of the drill rod 4 and the cam 7, a connecting wheel 6 is rotatably mounted on the bottom end of the drill rod 4, and the connecting wheel 6 is rolledly connected to the cam 7. By rotatably mounting the connecting wheel 6 on the bottom end of the drill rod 4, the connecting wheel 6 transforms the sliding friction between the drill rod 4 and the cam 7 into rolling friction, thereby reducing friction.

[0025] like Figure 1 and Figure 2 As shown. An annular groove is provided on the outer side wall of the connecting wheel 6, and the edge of the cam 7 is located within the annular groove. By opening an annular groove on the outer side wall of the connecting wheel 6, the annular groove is adapted to the cam 7, ensuring the stability of the connection between the connecting wheel 6 and the cam 7.

[0026] like Figure 2As shown. A connecting seat 14 is fixedly provided at the bottom end of the drill rod 4. The connecting seat 14 includes a mounting shaft located in the middle and ear plates connected to both ends of the mounting shaft. The ear plates are respectively fixedly connected to both sides of the drill rod 4. By providing the connecting seat 14 at the bottom end of the drill rod 4, the connecting wheel 6 is located on the extension line of the axis of the drill rod 4, so that the thrust applied by the cam 7 to the drill rod 4 is on the axis of the drill rod 4.

[0027] like Figure 1 As shown. An inclined plate is fixedly connected to one side of the mounting base 5, and a guide block 8 is installed on the inclined plate to guide the drill rod 4. By setting the guide block 8 on the mounting base 5, the two guide blocks 8 guide the bottom end of the drill rod 4, ensuring the stability of the movement of the drill rod 4.

[0028] like Figure 1 As shown. The guiding structure includes a guide plate 15 fixed to the top of the output end of the feed pipe 2 and a receiving tube 10 connected to the bottom of the hopper 1. The guide plate 15 has an opening for the guide plate 15 to pass through. The receiving tube 10 is located on the side wall of the hopper 1 away from the feed pipe 2. The top end of the chisel 4 is located inside the receiving tube 10. A limiting ring 12 is provided at the bottom end of the receiving tube 10 for the top end of the chisel 4 to pass through. The receiving tube 10 is connected to the hopper 1 and is coaxially arranged with the chisel 4. The top end of the receiving tube 10 is sealed, and the limiting ring 12 is provided inside the receiving tube 10. The limiting ring 12 guides the top end of the chisel 4, further improving the stability of the chisel 4.

[0029] like Figure 1 As shown. A limiting block 11 with an outer diameter larger than the inner diameter of the limiting ring 12 is fixedly connected to the top end of the drill rod 4. The limiting block 11 is located above the limiting ring 12. By setting the limiting block 11 at the top end of the drill rod 4, the limiting block 11 cooperates with the limiting ring 12 to prevent the drill rod 4 from slipping out of the hopper 1.

[0030] like Figure 1 As shown. The bottom of the feeding pipe 2 is provided with a variable diameter section, and the pipe diameter increases gradually along the material flow direction. Both sides of the bottom of the feeding pipe 2 are provided with inclined surfaces. By providing a variable diameter section at the bottom of the feeding pipe 2, the material flowing along the feeding pipe 2 flows out from the bottom of the feeding pipe 2. The gradually increasing pipe opening can prevent the material from clogging in the feeding pipe 2. The inclined surfaces on both sides of the feeding pipe 2, together with the inclined plate at the bottom of the feeding pipe 2, can make the material flow out from the bottom of the feeding pipe 2, avoiding interference between the feeding of the feeding pipe 2 and the driving component.

[0031] like Figure 1As shown, a spindle-shaped lever 9 is fixedly connected to the drill rod 4, and the lever 9 is located inside the feed end of the feed pipe 2. By fixing the lever 9 to the drill rod 4, the lever 9 increases the contact area between the drill rod 4 and the material, and the smooth surface of the lever 9 reduces the resistance to moving the material.
