Embodiment Construction

[0010] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0011] In order to solve the disadvantages of the high failure rate of the existing arch breaking device, the invention provides a feeder arch breaking structure, which has good arch breaking effect and low failure rate. In order to further illustrate the structure of the present invention, in conjunction with accompanying drawing detailed description is as follows:

[0012] see figure 1 , a feeder broken arch structure, including a feeder 1, the upper part of the feeder is a flaring-shaped upper lock 2, the upper part of the lock is a bin 3. The powder enters the upper lock from the silo, and the wet powder is easily arc...

Abstract

The invention discloses a feeder arch breaking structure, and belongs to the technical field of coal conveying. A feeder is included. The upper portion of the feeder is a flaring-like upper lock port,and the upper portion of the upper lock port is provided with a bin. The feeder arch breaking structure is characterized in that an arch breaking hydraulic cylinder is further included and located onone side in the upper lock port of the feeder, the lower end of the arch breaking hydraulic cylinder is arranged in the upper lock port of the feeder through a horizontal pin shaft, and the arch breaking hydraulic cylinder is provided with a cylinder rod capable of stretching out towards the bin; and a sleeve is arranged on the top of the cylinder rod, the side portion, close to the inner wall ofthe upper lock port, of the sleeve is provided with a wedged ridge, the position, corresponding to the wedged ridge, of the inner wall of the upper lock port is provided with an ejector rod, and a spring through which the wedged ridge abuts against the ejector rod is connected between the lower end of a cylinder body of the arch breaking hydraulic cylinder and the inner wall of the upper lock port. The feeder arch breaking structure is long in service life and good in arch breaking effect.

Description

technical field [0001] The invention belongs to the technical field of coal transportation, and in particular relates to an arch breaking structure of a feeder. Background technique [0002] At present, coal-fired power plants, coal mines, coking and other industries in my country mostly use plate feeders, screw feeders, drum feeders, and ordinary vibrating feeders for raw coal or loose materials in the lower part of the silo. Since the coal material is a loose material that is highly viscous, easy to block, easy to shed, or has poor downstream flow, it cannot be fed normally during the transportation process, resulting in the problem of high energy consumption and small feeding volume of the feeder during use. For this reason, our company has invented a kind of arch breaking device for the feeder. The hydraulic cylinder outside the upper lock of the feeder is extended to the silo, and the arch breaking is implemented through the hydraulic cylinder ejector rod and the vibrat...
