Description

Technical Field

[0001] The utility model belongs to the technical field of transportation, in particular to a fly ash transportation device. Background Art

[0002] Fly ash refers to the ash collected from the flue gas after coal combustion. Adding fly ash to concrete can save a lot of water and fine aggregate, reduce water consumption, improve the workability of concrete mixture, enhance the pumpability of concrete, improve the anti-permeability of concrete, and increase the modifier properties of concrete.

[0003] Most of the existing fly ash conveying devices only serve to convey fly ash, without considering the problem that the fly ash may be mixed with impurities. Such fly ash may affect the quality of the produced concrete when used. Therefore, the fly ash needs to be filtered. Therefore, we propose a fly ash conveying device. Utility Model Content

[0027] Gears 1 107 are fixedly connected to the mutually approaching sides of the driven rods 103. A gear 2 109 is meshed with the outer surface of the gear 1 107. There are two gear 2 109 in total. The parts included in the inner wall of the gear 2 109 are the same. A limit rod 108 is fixedly connected to the inner wall of the gear 2 109.

[0028] Half gears 110 are fixedly connected to the outer surface of the limit rod 108. A rack 112 is meshed with the mutually approaching sides of the half gears 110.

[0029] The transmission and feeding mechanism 2 includes a housing 201 rotatably connected to the outer surface of the limit rod 108. The inner wall of the housing 201 is slidably connected to the sliding bar 102, and the inner wall of the housing 201 is rotatably connected to the outer surface of the driven rod 103. A fixed frame 202 is fixedly connected to the outer surface of the housing 201, and a motor 203 is fixedly connected to the inner wall of the fixed frame 202. The bottom output shaft of the motor 203 is fixedly connected to a driving rod 204 through a coupling.

[0030] The outer surface of the driving rod 204 is rotatably connected to the inner wall of the housing 201. The outer surface of the driving rod 204 is fixedly connected to the inner wall of the second pulley 106. A third pulley 205 is fixedly connected to the outer surface of the driving rod 204.

A rotating rod 208 is fixedly connected to the inner wall of the fourth pulley 207. By driving the third pulley 205 to rotate through the driving rod 204, the third pulley 205 can cooperate with the fourth pulley 207 to move the conveyor belt 206, achieving the effect that the conveyor belt 206 can convey fly ash only through the operation of the motor 203.

[0032] A specific application of this embodiment is as follows: When using this device, first operate the transmission and feeding mechanism 2. The motor 203 can be started. The position of the motor 203 is fixed by the fixed frame 202 on the housing 201, so that the motor 203 will not rotate by itself. After the motor 203 is started, the driving rod 204 will perform a high-speed rotational motion. The rotation of the driving rod 204 will drive the pulley three 205 to rotate together, so that the pulley three 205 will drive the pulley four 207 to rotate through the conveyor belt 206, thus completing the movement of the conveyor belt 206. The position of the pulley four 207 is fixed by the rotating rod 208. Then, the pulverized coal to be transported is poured into the feeding channel 209 through the pouring pipe 210, so that the fly ash enters the device. The driving rod 204 drives the pulley three 205 to rotate, so that the pulley three 205 can cooperate with the pulley four 207 to move the conveyor belt 206, achieving the effect that only through the operation of the motor 203, the conveyor belt 206 can transport the fly ash. The fly ash will first pass through the vibrating and screening mechanism 1. At this time, the rotation of the driving rod 204 will also drive the pulley two 106 to rotate. The pulley two 106 drives the pulley one 104 to rotate together through the belt 105. The position of the pulley one 104 is restricted by the driven rod 103, so that the pulley one 104 will not shift. While the pulley one 104 drives the driven rod 103 to rotate, the driven rod 103 will make the gear one 107 rotate. The pulley one 104 drives the driven rod 103 to rotate through the pulley two 106 and the belt 105, so that the gear one 107 can drive the gear two 109 to rotate. Furthermore, the semi-gear 110 can make the rack 112 drive the screening frame 101 to move back and forth, completing the shaking of the screening frame 101, achieving the effect that the screening frame 101 can filter the impurities in the fly ash. Thus, the gear one 107 drives the gear two 109 to rotate. Then, the gear two 109 will drive the limiting rod 108 to rotate together, and the rotation of the limiting rod 108 will also drive the semi-gear 110 to rotate together, so that the semi-gear 110 drives the rack 112 to move back and forth. The rack 112 will drive the screening frame 101 to move back and forth through the connecting frame 111. When the screening frame 101 moves back and forth, the position of the screening frame 101 is restricted by the slidable sliding bar 102, thereby filtering the fly ash.
