Background Art

[0002] At present, the vibrating activated feeder widely used in my country's coal, power and other industries requires uniform material size and good looseness, especially when the material meets water under the powder ore pile, it will form mud, which is easy to flow by itself and easy to stick to the feeder, which will cause blockage over time. The life of the feeder is reduced due to the increase in load. The existing impeller activated feeder has the disadvantage of being inconvenient to maintain and repair because the drive device is installed inside the feeder. Now there is a special need for a new type of externally driven impeller activated feeder with a simple structure, which is not affected by the size of powder and material moisture, and can prevent the silo from being blocked to achieve high efficiency, stable operation, and easy maintenance.

The utility model completely overcomes the drawbacks of unstable operation of the movable cone, which causes impact on the external trough box and uneven feeding, and greatly prolongs the service life of the equipment.

[0007] Compared with the prior art, the utility model is innovative in that the motor is arranged outside the trough box and is driven by a chain, the feeder outlet is below the trough box along the belt direction, the size can be adjusted according to the feeding amount, the impeller blades rotate to push the material vertically and evenly to the center of the belt, which can prevent the belt from deviation, reduce belt loss, reduce production costs, transmit force more smoothly, have a simpler structure, are easier to install and replace, reduce maintenance, and improve work efficiency.

[0008] Compared with the prior art, the utility model is innovative in that the material distribution cone of the activated feeder can be opened at any time according to the sticking condition of the material above, and the vibration motor is turned off when the material flows smoothly, thereby reducing energy consumption, reducing production costs, requiring a small installation space, and reducing equipment investment costs.

[0009] Compared with the prior art, the utility model has good overall sealing, environmental protection, low installation space, stable operation, simple structure, firmness and durability, easy installation and maintenance, greatly reducing production costs, and is particularly suitable for use in occasions where the center line of the silo opening is perpendicular to the drop point and powder and viscous materials are transferred and fed.

Its technical characteristics are: a movable cone 2 is installed inside the outer trough box 1, a support plate 3 is arranged inside the movable cone 2, and the two ends of the lower side of the support plate 3 are respectively connected to the upper part of the rubber spring group 4, the lower part of the rubber spring group 4 is on the motor seat 5, and a vibration motor 6 is installed under the motor seat 5, and the vibration motor 6 penetrates into the material distribution On the top of the cone 7, the reducer base 10 is installed under the distribution cone 7, the reducer 8 is installed on the reducer base 10, the output shaft below the reducer 8 is connected with a coupling 11, the lower part of the coupling 11 is connected to the impeller shaft 12, the impeller shaft 12 passes through the lower part of the distribution cone 7 and connects the impeller blade 12.1 in the middle position of the lower box body 13, the upper part of the lower box body 13 is connected to the lower part of the outer tank box 1, and the lower part of the lower box body 13 is provided with a discharge port 13.1, and the motor 14 is installed on the outside of the outer tank box 1, and the motor 14 is connected to the reducer 8 through the chain 9.

[0016] The working principle of a new type of externally driven impeller activated feeder is: under the control of electrical equipment, the motor installed outside the outer trough box drives the reducer under the material distribution cone through the chain, the reducer drives the impeller shaft to rotate through the coupling, and the impeller blades at the bottom of the impeller shaft also rotate accordingly. During the rotation, the impeller blades drive the material to be discharged from the feeder outlet. The feeder outlet is below the trough box along the belt direction, and the size can be adjusted according to the feeding amount. The impeller blades rotate to push the material vertically and evenly to the center of the belt, which can prevent the belt from running off, reduce the belt loss and complete the feeding process. When the material at the silo is blocked, the vibration motor under the active cone can be turned on at any time, and the rubber spring group drives the active cone to prevent the outer trough box from participating in the vibration, and the material is distorted to prevent the material in the silo from blocking. When the material is normal, the vibration motor does not start. The utility model has good overall sealing, environmental protection, low installation space, stable operation, simple structure, firmness and durability, and convenient installation and maintenance. It is particularly suitable for occasions where the center line of the silo is perpendicular to the drop point and powder and viscous materials are transferred and fed.
