During the whole process, the speed of adding coal to the boiler can be adjusted by adjusting the rotation speed of the first turntable 506 through the driving mechanism 6, so that the amount of coal added can be accurately adjusted according to demand, while also reducing the workload of the staff.

[0035] Specifically, the feeding mechanism 8 includes two fixed frames 801, the two fixed frames 801 are fixedly connected to the outer side of the side plate 7, the interior of the two fixed frames 801 are rotatably connected to the third screw 802, and the ends of the two third screws 802 away from the storage hopper 504 are both extended to the outside through the fixed frame 801, the ends of the two third screws 802 away from the storage hopper 504 are both fixedly connected to the second bevel gear 807, the outer sides of the two third screws 802 are both threadedly sleeved with sliders 803, and the two sliders 803 are respectively in the opposite The corresponding fixed frame 801 slides internally, and a loading box 804 is rotatably connected between the two sliders 803. The inner cavity of the loading box 804 is fixedly connected to the side of the side plate 7 with a counterweight 809. The outer side of the side plate 7 is fixedly connected to a second fixed seat 808. The top of the second fixed seat 808 is fixedly connected to a dual-axis forward and reverse motor 805. The two output ends of the dual-axis forward and reverse motor 805 are fixedly connected to the first bevel gear 806. The two first bevel gears 806 are respectively engaged with the corresponding second bevel gear 807.

[0036] In this embodiment, when it is necessary to add coal to the storage hopper 504, the dual-axis forward and reverse motor 805 is first started. At this time, the two output ends of the dual-axis forward and reverse motor 805 start to rotate, and then drive the two first bevel gears 806 to start rotating. Then, the two first bevel gears 806 respectively drive the meshing second bevel gears 807 to start rotating. Then, the two second bevel gears 807 respectively drive the fixed third screw 802 to start rotating. Then, the two third screws 802 respectively drive the threaded sliders 803 to slide upward along the fixed frame 801. Then, the two sliders 803 drive the transferred loading box 804 to move upward. When the slider 803 rises to a certain height, the loading box 804 is flipped toward the storage hopper 504 under the action of the counterweight block 809, so that the coal in the loading box 804 falls into the storage hopper 504.

[0037] Specifically, the driving mechanism 6 includes a first fixed seat 601, which is fixedly connected to the top of the storage plate 4. The top of the first fixed seat 601 is fixedly connected to a single-axis forward and reverse motor 602, and the output end of the single-axis forward and reverse motor 602 is fixedly connected to a second turntable 606. The outer side of the fixed plate 13 is rotatably connected to a rotating shaft 603, and the end of the rotating shaft 603 away from the fixed plate 13 is fixedly connected to a driving gear 604.

[0038] In this embodiment, when it is necessary to drive the slag discharge mechanism 2, the connecting rod 605 is first transferred to the outside of the second turntable 606 and the driving gear 604 through the limiting mechanism 14, and then the single-axis forward and reverse motor 602 is started. At this time, the output end of the single-axis forward and reverse motor 602 starts to rotate, and then drives the second turntable 606 to rotate, and then drives the driving gear 604 to rotate through the connecting rod 605. The driving gear 604 can drive the spur gear 208 meshing with it to rotate, so that the slag discharge mechanism 2 can operate. When it is necessary to drive the feeding mechanism 5, the connecting rod 605 is first transferred to the outside of the second turntable 606 and the first turntable 506 through the limiting mechanism 14, and then the single-axis forward and reverse motor 602 is started. At this time, the output end of the single-axis forward and reverse motor 602 starts to rotate, and then drives the second turntable 606 to rotate, and then drives the first turntable 506 to rotate through the connecting rod 605, so that the feeding mechanism 5 can operate. By setting the driving mechanism 6, one motor can be used to drive two mechanisms, reducing the use of motors and saving costs.

[0039] Specifically, the three limiting mechanisms 14 include three limiting columns 1401, which are respectively fixedly connected to the outside of the first turntable 506, the second turntable 606, and the driving gear 604.

[0040] In this embodiment, when the connecting rod 605 needs to be fixed, the connecting rod 605 is first sleeved on the outside of the limiting column 1401, and then pressed down with force. Under the action of pressure, the two limiting blocks 1403 slide in the opposite direction along the sliding groove 1402, so that the spring 1405 is compressed. When the connecting rod 605 completely passes through the limiting block 1403, the two limiting blocks 1403 move in the opposite direction along the sliding groove 1402 under the push of the spring 1405, and finally the limiting block 1403 extends out of the sliding groove 1402, so that the connecting rod 605 will not slip during the rotation process.

[0041] Specifically, a ladder 12 is fixedly connected to the side of the storage hopper 504, and the step surface of the ladder 12 is provided with anti-slip grooves.

[0042] In this embodiment, the ladder 12 can be provided to facilitate workers to observe the coal reserves inside the storage hopper 504, and the anti-slip grooves can increase friction to prevent workers from slipping.

[0043] Specifically, a handle 10 is fixedly connected to the side of the slag collecting box 9, and four universal wheels 11 are correspondingly distributed on the bottom of the slag collecting box 9.

[0044] In this embodiment, the provided handle 10 and four universal wheels 11 can facilitate the workers in removing the coal slag.

[0045] The working principle and use process of the present invention are as follows: when the slag after burning in the boiler needs to be transported out, the driving mechanism 6 is first used to drive one of the spur gears 208 to rotate, and then the meshing teeth drive the other spur gear 208 to rotate, and then the threaded sleeve 207 fixed to the two spur gears 208 is driven to rotate, and then the two threaded sleeves 207 respectively drive the first screw 204 and the second screw 206 to move outward through the threads, and then the first screw 204 drives the connecting plate 203 to slide in the first slide plate 201, and then drives the slag collecting ring 209 to move together, and at the same time, the second screw The rod 206 drives the bottom plate 205 to slide along the second slide plate 202, and the bottom plate 205 moves in the same direction and speed as the slag collecting ring 209. At this time, the coal slag in the slag collecting ring 209 is pulled out. When the thread of the first screw 204 is disengaged from the threaded sleeve 207, the connecting plate 203 and the slag collecting ring 209 stop moving, while the second screw 206 continues to move forward under the action of the threaded sleeve 207, so that the bottom plate 205 gradually disengages from the slag collecting ring 209, which makes the coal slag in the slag collecting ring 209 fall, thereby achieving the effect of automatically cleaning the coal slag and reducing the workload of the staff.

[0046] When coal needs to be added to the boiler, the first turntable 506 is first driven to rotate by the driving mechanism 6, and then the stacking screw 503 is driven to rotate. At this time, the coal dropped from the storage hopper 504 through the discharge pipe 505 to the inside of the shell 502 can be transported to the boiler by the rotation of the stacking screw 503. During the whole process, the speed of adding coal to the boiler can be adjusted by adjusting the rotation speed of the first turntable 506 through the driving mechanism 6, so that the amount of coal added can be accurately adjusted according to demand, while also reducing the workload of the staff.

[0047] When it is necessary to add coal to the storage hopper 504, first start the dual-axis forward and reverse motor 805. At this time, the two output ends of the dual-axis forward and reverse motor 805 start to rotate, and then drive the two first bevel gears 806 to start rotating. Then, the two first bevel gears 806 respectively drive the meshing second bevel gears 807 to start rotating. Then, the two second bevel gears 807 respectively drive the fixed third screw 802 to start rotating. Then, the two third screws 802 respectively drive the threaded sliders 803 to slide upward along the fixed frame 801. Then, the two sliders 803 drive the transferred loading box 804 to move upward. When the slider 803 rises to a certain height, the loading box 804 is flipped toward the storage hopper 504 under the action of the counterweight block 809, so that the coal in the loading box 804 falls into the storage hopper 504.

[0048] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
