Description

Technical Field

[0001] The utility model relates to a novel belt type activating feeder, which is mainly used for intermediate transfer feeding in the material conveying process of various industries such as coal, metallurgy, and electric power, and belongs to the technical field of vibratory conveying feeding. Background Art

[0002] At present, in industries such as coal, metallurgy, and electric power in our country, an activating feeder with the vertical position of the bin opening above the belt is widely used. It has a good effect when the material particle size is uniform. When the machine stops, the activating feeder locks the material itself to prevent material slipping. However, in the case where the material particle size often changes, when the small particle material cannot be self-locked, material slipping occurs and forms a bin cross-flow, resulting in the material on the lower belt overflowing and being pressed to death. When the material particles become larger, it will cause blockage and arching in the feeder, making the material unable to be fed onto the belt, which is a major problem affecting production efficiency. Now, there is a particular need for a novel belt type activating feeder with a simple structure, good sealing performance, suitable for conveying materials with different particle sizes, capable of preventing material self-flow and blockage and arching, and achieving stable operation and simple operation. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a novel belt type activating feeder with a simple structure, good sealing performance, suitable for conveying materials with different particle sizes, capable of preventing material self-flow and blockage and arching, and achieving stable operation and simple operation.

[0004] To achieve the above object, the technical solution adopted by the utility model to solve its technical problem is: a novel belt type activating feeder, which is composed of a feed hopper, an observation window, a distributor, a rubber spring, a connecting rod, a motor base, a vibration motor, a flap gate, an electro-hydraulic push rod, a support, an upper leg, a lower leg, a belt feeder, and a base. Its technical characteristics are: observation windows 2 are arranged on both outer sides of the feed hopper 1, a distributor 3 is installed inside, a rubber spring 4 is installed below the distributor 3, the rubber spring 4, the bottom plate 1.1 below the distributor 3, and the motor base 6 are connected together through a connecting rod 5, a vibration motor 7 is installed below the motor base 6, flap gates 8 are installed below the inclined bottom plates 1.2 on both sides of the feed hopper 1, one side of the flap gate 8 is connected to the front end of an electro-hydraulic push rod 9, the rear part of the electro-hydraulic push rod 9 is installed on the lower part of the feed hopper 1 through a support 10, upper legs 11 are arranged on the outer sides of both ends of the feed hopper 1, the upper parts of the upper legs 11 are connected to the upper parts of the lower legs 12, the lower parts of the lower legs 12 are connected to the base 14, and belt feeders 13 are respectively installed at the upper parts of both ends of the base 14.

[0005] The utility model has the following characteristics when adopting the above structure compared with the prior art.

[0006] Compared with the prior art, the innovation of this utility model is that at the bottom of the activation feeder, two belt feeders are used to convey materials correspondingly, enabling the materials to be concentrated and evenly fed to the center of the lower belt. The feeding speed is not affected by the change of the particle size of the materials, effectively preventing the belt deviation caused by the materials not reaching the center of the belt, reducing the belt loss, greatly reducing the production cost and improving the economic efficiency.

[0007] Compared with the prior art, the innovation of this utility model is that a flap gate is arranged at the feeding port of the belt feeder fed by the feeding hopper, and the size of the feeding port above the belt feeder can be adjusted at any time by the electro-hydraulic push rod. It can not only adjust the feeding amount but also avoid the blockage caused by the change of the particle size of the materials, and the operation is convenient and simple.

[0008] The main body of the feeder of this utility model does not participate in vibration. The vibration motor drives the distributor to agitate the materials at the bin opening to prevent arching. It has an activation function and can also be opened or closed according to the material conditions at the bin opening. The vibration motor drives the distributor through evenly distributed rubber springs, making the operation of the distributor smoother, with less noise, better vibration damping effect of the main body of the feeder and smoother operation, so as to reduce energy consumption, lower the production cost and greatly extend the service life of the equipment.

[0009] Compared with the prior art, the observation windows arranged on both sides of the feeding hopper of this utility model are not only convenient for observing the materials in the bin, but also can be used for maintenance under the distributor, facilitating installation, repair and maintenance, and greatly reducing the production cost.

[0010] Compared with the prior art, the two belt feeders arranged below of this utility model can not only run simultaneously to vary the feeding amount by adjusting the belt speed, with simple and convenient operation. When maintenance is needed, it does not require all shutdown. One feeder can be shut down for maintenance while the other can continue to run without affecting the production progress, and the production rate can also be greatly improved.

[0011] A new type of belt activation feeder adopted by this utility model has simple connection structures of each component, convenient maintenance and high production efficiency, and is especially suitable for the occasions where the center line of the bin opening is perpendicular to the material dropping point and the materials are transferred and fed with changing particle sizes.

Its technical features are: observation windows 2 are provided on both outer sides of the feed hopper 1, a distributor 3 is installed inside, a rubber spring 4 is installed below the distributor 3, and the rubber spring 4, the bottom plate 1.1 below the distributor 3 and the motor base 6 are connected together through a connecting rod 5. A vibration motor 7 is installed below the motor base 6. Flap gates 8 are installed below the inclined bottom plates 1.2 on both sides of the feed hopper 1. One side of the flap gate 8 is connected to the front end of the electro-hydraulic push rod 9. The rear part of the electro-hydraulic push rod 9 is installed below the feed hopper 1 through a support 10. Upper legs 11 are provided on the outer sides of both ends of the feed hopper 1. The upper legs 11 are connected to the upper parts of the lower legs 12. The lower parts of the lower legs 12 are connected to the base 14. Belt feeders 13 are respectively installed on the upper parts of both ends of the base 14.

[0017] The working principle of a new type of belt activation feeder is: under the control of electrical equipment, the materials in the feed hopper are respectively fed to two belt feeders through the distributor. The belt feeder operates to convey the materials to the discharge port to complete the feeding process. The vibration motor can be opened or closed at any time according to the smoothness of the materials on the distributor. When the vibration motor is opened, it drives the distributor to agitate the materials to prevent the materials in the bin from sticking and blocking. When the materials are normal, the vibration motor does not start. The flap gate at the discharge port below the feed hopper is pushed by the electro-hydraulic push rod to adjust the size of the discharge port, which can not only adjust the feeding amount, but also effectively prevent the materials in the feed hopper from being blocked. The utility model has the advantages of simple structure, stable operation, convenient maintenance and high production efficiency, and is particularly suitable for the occasions where the center line of the bin outlet is perpendicular to the falling point and the materials are transferred and fed with changing particle sizes.
