[0023] 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.

[0024] refer to Figures 1-2 and Figure 4 As shown, the present invention provides an automatic coal blending and quantitative feeding device, comprising: a distribution tank 4 installed above a conveyor belt 1, a feeding hopper 6 at the top of the distribution tank 4, a weighing device 13 located below the feeding hopper 6 in the distribution tank 4, a weighing area for weighing coal formed between the feeding hopper 6 and the weighing device 13, and multiple vertical circular storage bins 8 arranged in a circular array in the distribution tank 4, with a rotating mechanism at the axis of the multiple storage bins 8 for rotation, so that the multiple storage bins 8 pass through the weighing area in sequence based on the rotation.

[0025] Combination Figure 2 and Figure 4 As shown, the inside of the material distribution tank 4 is provided with an annular groove 11, the weighing device 13 is embedded in the annular groove 11, the discharge port 12 is opened at the bottom of the annular groove 11, and the bottom ends of multiple storage tanks 8 are all in contact with the annular groove 11.

[0026] Combination Figures 1-2 and Figure 4 As shown, the bottom of the distribution tank 4 is provided with a discharge pipe 3 for discharging materials on the side away from the feed hopper 6, and the discharge pipe 3 is located above the conveyor belt 1. The side of the distribution tank 4 away from the weighing device 13 has a discharge port 12 that is connected to the discharge pipe 3. Based on the rotation, the bottoms of multiple storage bins 8 pass through the discharge port 12 in sequence.

[0027] As described above, using the conveyor belt 1, distribution tank 4, feed hopper 6, weighing device 13, multiple storage bins 8, and rotating mechanism provided by this utility model, the multiple storage bins 8 are confined within the annular area of ​​the distribution tank 4 by the annular groove 11. When one of the storage bins 8 is below the feed hopper 6, the weighing device 13 engages with the bottom end of the storage bin 8. At this time, the coal in the feed hopper 6 falls into the storage bin 8 and is weighed by the weighing device 13. When the weighing device 13 detects that the weight has reached the threshold, the weighing device 13 sends an electrical signal to the rotating mechanism. At this time, the rotating mechanism drives the storage bin 8 to rotate, which facilitates bringing the next storage bin 8 to the bottom of the feed hopper 6. The storage bin 8 containing coal rotates to the discharge port 12 and falls onto the conveyor belt 1 through the discharge pipe 3. The conveyor belt 1 carries a fixed amount of coal to the next workstation. Repeating the above steps completes the continuous quantitative coal dispensing operation of the equipment.

[0028] Furthermore, to avoid ineffective material feeding from multiple storage bins 8 during rotation, refer to... Figure 2 and Figure 5 As shown, the top of multiple storage bins 8 is equipped with a cover plate 9 that seals the bottom of the feed hopper 6. The bottom of the feed hopper 6 abuts against the cover plate 9. Multiple feed inlets 10 are arranged in a ring array on the cover plate 9, with one end of each feed inlet 10 extending into the corresponding storage bin 8. Due to rotation, the multiple feed inlets 10 pass through the weighing area in sequence. When the multiple storage bins 8 rotate in the annular groove 11, the cover plate 9 seals the bottom of the feed hopper 6 during rotation, thereby preventing coal in the feed hopper 6 from falling into the gap between two adjacent storage bins 8. When the storage bin 8 is below the feed hopper 6, it is convenient for the feed inlets 10 to allow coal to enter the storage bin 8.

[0029] Furthermore, to facilitate the rotation of multiple storage bins 8, refer to Figures 1-2 and Figure 4 As shown, the rotating mechanism includes a motor 5 and a rotating shaft 7 installed at the output end of the motor 5. The motor 5 is installed on the top of the dispensing tank 4, and one end of the rotating shaft 7 is connected to the outer wall of multiple storage tanks 8. A cover plate 9 is fitted onto the rotating shaft 7. The motor 5 facilitates the rotation of the rotating shaft 7, thereby facilitating the simultaneous rotation of multiple storage tanks 8.

[0030] Furthermore, to facilitate the suspension of the distribution tank 4 above the conveyor belt 1, refer to... Figure 2 As shown, a gantry frame 2 is provided above the conveyor belt 1 for support, and the distribution tank 4 is installed on top of the gantry frame 2. The distribution tank 4 can be suspended above the conveyor belt 1 by the gantry frame 2, so that coal can fall directly onto the conveyor belt 1 through the feed pipe 3.

[0031] In this utility model, combined with Figures 2-3As shown, the bottom of the feed hopper 6 in this embodiment is also fitted with a liftable collar 14. A pressing mechanism is provided in the longitudinal direction between the collar 14 and the distribution tank 4, so that the collar 14 is always in contact with the cover plate 9 based on the pressing.

[0032] Combination Figure 3 As shown, the pressing mechanism includes at least a guide rod 15, a spring 16, and a mounting base 17. The top end of the guide rod 15 is welded to the top of the dispensing tank 4. One end of the mounting base 17 is welded to the outer wall of the collar 14, and the mounting base 17 is sleeved on the guide rod 15. The spring 16 is installed between the top of the dispensing tank 4 and the mounting base 17, and the spring 16 is sleeved on the guide rod 15.

[0033] As described above, when using the collar 14 provided by this utility model, the collar 14 is always pressed against the cover plate 9 by the pressing mechanism. When the cover plate 9 rotates with multiple storage bins 8, the mounting seat 17 on the collar 14 is adjusted up and down on the guide rod 15 by the elastic force of the spring 16, so that the bottom end of the collar 14 always abuts against the cover plate 9, avoiding the material discharge gap between the feed hopper 6 and the cover plate 9 when the cover plate 9 rotates, thereby preventing coal from overflowing outward through the material discharge gap.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
