[0032] Example 1
[0033] The utility model provides a concrete raw material storage and unloading device, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a discharge channel 2 arranged at the bottom of the storage bin 1, and a first valve 4 and a second valve 5 are arranged on the discharge channel 2;
[0034] When unloading is required, the second valve 5 is closed first, and the first valve 4 is opened, so that the raw materials enter the unloading chamber from the storage bin 1, and the fan is turned on at the same time, so that the external airflow enters the dust removal channel 8 from the air inlet 9, and enters the unloading chamber from the through hole 10 on one side of the unloading channel 2, blowing the dust contained in the raw materials, so that the dust diffuses in the unloading chamber, and under the continuous blowing of the external airflow, the dust is discharged from the through hole 10 provided on the other side, enters the dust removal channel 8, and finally falls into the bag dust collector connected to the dust removal pipeline, so as to achieve dust treatment, avoid the generation of a large amount of dust during the unloading process and avoid flying everywhere, causing the mixing station to be filled with dust, affecting the health of the staff; in addition, the first shaking plate 11 is shaken back and forth in the dust removal chamber 6 along the radial direction, so that the dust remaining on the pipe wall is shaken off, so as to avoid the dust accumulation on the pipe wall blocking the through hole 10, resulting in reduced dust removal efficiency;
[0035] When the raw materials falling into the discharge chamber are about to reach the position of the through hole 10, the first valve 4 is closed to prevent the raw materials from overflowing from the through hole 10. When the dust treatment is completed, the second valve 5 is opened to allow the raw materials to fall from the discharge port 7 and fall onto the belt conveyor mechanism 3. The belt is driven by the motor to move, driving the raw materials to be transported to the mixing main building to achieve the mixing of the concrete raw materials.
[0036] Example 2
[0037] On the basis of Example 1, Figure 2 and Figure 3 As shown, during dust removal, the rotary disc 15 is driven to rotate clockwise by the rotating motor 17, so that the outer teeth 19 and the inner teeth 20 provided on the rotary disc 15 are alternately meshed with the second gear 18 in turn, and the first gear 16 is driven to rotate clockwise and counterclockwise in turn, thereby driving the first gear 16 to rotate reciprocatingly. Since the first gear 16 is meshed with the gear ring 13, the gear ring 13 is driven to rotate reciprocatingly. Since the two ends of the connecting block 14 are respectively rotatably connected with the gear ring 13 and the slider 12, the slider 12 is driven to slide reciprocatingly on the dust removal channel 8 and the discharge channel 2, so that the first shaker plate 11 and the second shaker plate 21 are reset and swung on the discharge channel 2 and the dust removal channel 8 respectively, so that the pipe wall vibrates, and the dust remaining on the pipe wall is shaken off, so as to avoid the dust accumulation on the pipe wall blocking the through hole 10, resulting in reduced dust removal efficiency; in addition, the mechanical structure controls the simultaneous reciprocating movement of several sliders 12, simplifies the steps of controlling the simultaneous shaking of several first shaker plates 11, and reduces the cost required for manufacturing the driving device and the space required for installation.
[0038] Example 3
[0039] On the basis of Example 1, Figure 1 and Figure 4As shown, during dust removal, the external airflow drives the dust to flow into the dust removal channel 8, and the guide of the guide plate 24 makes the external airflow contact with the push plate 23 located below the roller 22, so that the roller 22 generates torque, which pushes it to rotate clockwise in the dust removal channel 8 until the support block 25 provided on the roller 22 contacts the inclined surface 27 provided on one side of the limit block 26, and the component force acting on the limit block 26 drives the limit block 26 to move downward and compress the spring 29. When the wind force of the external airflow is greater than the rebound force of the corresponding position of the spring 29, the support block 25 passes through the support block 25 smoothly, pushing the roller 22 to continue to rotate clockwise in the dust removal channel 8, so that the dust passes through the roller 22 smoothly and enters the subsequent bag dust collector, so as to realize the dust treatment, and the limit block 26 is driven to reset under the action of the rebound force of the spring 29;
[0040] When the dust removal is stopped and the dust flows back to push the push plate 23, the dust is guided by the guide plate 24 so as to contact the push plate 23 below the roller 22. The torque generated drives the roller 22 to rotate counterclockwise until the support block 25 contacts the vertical surface 28 provided on the other side of the limit block 26, thereby limiting the roller 22 from continuing to rotate counterclockwise and preventing the dust from flowing back into the discharge channel 2.
