Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model discloses a fly ash conveying mechanism, comprising a mounting frame 1, a screening device 2 is fixedly mounted on the top of the mounting frame 1, a first conveying structure 4 is arranged at the feeding port of the screening device 2, a second conveying structure 5 is arranged at the discharging port of the screening device 2, and a collecting box 3 is arranged in front of the second conveying structure 5; a control panel 6 is fixedly mounted on the outer side of the mounting frame 1, and the control panel 6 is electrically connected to the screening device 2, the first conveying structure 4 and the second conveying structure 5 respectively; the screening device 2 comprises a screening box 201, the inner wall of the screening box 201 is rotatably connected to two crushing shafts 203 through a built-in power supply, the inner wall of the screening box 201 is movably connected to a screening plate 204 through a damping spring 205, a vibration motor 206 is arranged at the bottom of the screening plate 204, and a transmission belt 212 is arranged on the inner wall of the screening box 201 through a built-in power supply.

[0023] The inner wall of the screening box 201 is slidably connected with a spreading brush 208 via an electric slide rail 207 , and the spreading brush 208 is located above the screening plate 204 .

[0024] The working principle of the electric slide rail 207 has been described in detail in a SMT placement machine positioning device with patent publication number CN202322179404.9, and will not be elaborated here.

[0025] The inner wall of the screening box 201 is provided with a recovery port 209 , and a recovery box 210 is movably connected to the outer side of the recovery port 209 .

[0026] By setting up the screening device 2, the fly ash can be crushed by the crushing shaft 203, and the crushed fly ash can be screened through the screening plate 204 in conjunction with the vibration motor 206, so that the fly ash that meets the filtering rules can be subsequently transported, while the fly ash that does not meet the filtering rules will be swept into the recovery box 210 driven by the spreading brush 208 driven by the electric slide rail 207 and wait for the next round of screening, thereby avoiding the situation where the fly ash is attached to the conveyor belt due to agglomeration during the transportation process, so that the fly ash can be smoothly transported.

[0027] Specifically, a guide plate 202 and a material discharge inclined plate 211 are fixedly mounted on the inner wall of the screening box 201 . The guide plate 202 is located above the crushing shaft 203 , and the material discharge inclined plate 211 is located above the transmission belt 212 .

[0028] In this embodiment, the fly ash can be guided and processed by using the guide plate 202 and the discharge inclined plate 211.

[0029] Specifically, the first conveying structure 4 and the second conveying structure 5 have the same specifications. The first conveying structure 4 includes a driving plate 501. The inner side of the driving plate 501 is rotatably connected to a conveyor belt 502 through an external power supply. A driving frame 503 is fixedly installed above the driving plate 501. A water storage barrel 504 and an extraction pump 505 are fixedly installed inside the driving frame 503. One end of the extraction pump 505 is connected to the water storage barrel 504. The other end of the extraction pump 505 is fixedly installed with an adjusting nozzle 506. The adjusting nozzle 506 is located below the driving frame 503.

[0030] In this embodiment, when the fly ash is on the first conveying structure 4 and the second conveying structure 5, the conveyor belt 502 is driven to rotate by an external power supply, so that the fly ash is transported on the conveyor belt 502;

[0031] At the same time, the extraction pump 505 is turned on, so that the extraction pump 505 extracts the humidification water in the water storage barrel 504, prompting the humidification water to be sent into the regulating nozzle 506 through the extraction pump 505 and finally sprayed out through the regulating nozzle 506, prompting the humidification water to contact with the fly ash, so that the humidification water has a dust reduction effect on the flying fly ash particles.

[0032] When in use, the fly ash is first sent into the screening device 2 through the first conveying structure 4, and then the fly ash falls onto the second conveying structure 5 after being processed by the screening device 2, and then the second conveying structure 5 sends the fly ash into the collecting box 3;

[0033] When the fly ash is on the first conveying structure 4 and the second conveying structure 5, the conveyor belt 502 is driven to rotate by an external power supply, so that the fly ash is transported on the conveyor belt 502;

[0034] At the same time, the extraction pump 505 is turned on, so that the extraction pump 505 extracts the humidification water in the water storage barrel 504, so that the humidification water is sent into the regulating nozzle 506 through the extraction pump 505 and finally sprayed out through the regulating nozzle 506, so that the humidification water contacts the fly ash, so that the humidification water plays a role in reducing dust on the flying fly ash particles;

[0035] When the fly ash enters the screening box 201, it passes through the two guide plates 202 and falls between the two crushing shafts 203. Then the built-in power supply is started, so that the built-in power supply drives the two crushing shafts 203 to rotate, so that the two crushing shafts 203 start to rotate relative to each other, causing the fly ash to be crushed between the two crushing shafts 203.

[0036] The fly ash after being crushed then falls on the screening plate 204, and then the electric slide rail 207 is started, so that the movable end of the electric slide rail 207 drives the spreading brush 208 to flatten the fly ash, and then the vibration motor 206 is started, so that the vibration motor 206 starts to drive the screening plate 204 to vibrate slightly, so that the fly ash that meets the filtering rules continues to fall, while the fly ash that does not meet the filtering rules will remain on the screening plate 204;

[0037] Then the electric slide rail 207 is started again, so that the electric slide rail 207 drives the spreading brush 208 to sweep the fly ash on the screening plate 204 into the recovery port 209 and finally falls into the recovery box 210;

[0038] The fly ash that passes through the screening plate 204 will fall onto the conveyor belt 212 along the discharge inclined plate 211 and be sent out of the screening box 201 along the conveyor belt 212 .

[0039] To sum up, the fly ash conveying mechanism, by setting up a screening device 2, can crush the fly ash using the crushing shaft 203, and then cooperate with the vibration motor 206 to screen the crushed fly ash through the screening plate 204, so that the fly ash that meets the filtering rules can be subsequently conveyed, and the fly ash that does not meet the filtering rules will be swept into the recovery box 210 driven by the spreading brush 208 driven by the electric slide rail 207 and wait for the next round of screening, thereby avoiding the situation where the fly ash adheres to the conveyor belt due to agglomeration during the conveying process, so that the fly ash can be smoothly conveyed.

[0040] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
