Abstract
The utility model relates to a noise reducing device for a coal feeder, wherein the noise reducing device is installed below the coal feeder to replace an original floating-type vibration isolation spring and support the whole coal feeder. The noise reducing device comprises a vibration isolation spring with two retracted ends and bolts connected with the coal feeder and a coal feeder rack. The noise reducing device of the utility model, which has a simple structure, overcomes the defect of loud noise generated by collision between floating-type vibration isolation springs of conventional coal feeders and coal feeder racks, and achieves effective decrease in vibration noise of coal feeders.
Description
Technical field
The utility model relates to feeder equipment, is specifically related to a kind of feeder noise-decreasing device, belongs to International Classification of Patents B65G27/08 " jigging conveyer " technical field.
Background technology
Feeder generally is indoor installation, and the vibration noise of feeder causes certain influence to routine and the physical and mental health of personnel it near, and the feeder vibration noise is greatly present ubiquitous problem.
Summary of the invention
The utility model provides a kind of feeder noise-decreasing device that can effectively reduce the feeder vibration noise at the deficiencies in the prior art.
Technical characterictic of the present utility model is the isolation spring that adopts the two ends collapsed shape, and it is fixing that feeder is suspended, the noise of having avoided isolation spring and feeder and feeder support to produce because of the vibration bump.Vibration noise when having reduced the feeder operation.
Below introduce structure of the present utility model in detail, a kind of feeder noise-decreasing device, it is characterized in that: by the isolation spring of two ends collapsed shape, respectively with feeder and feeder support bonded assembly bolt, and flat gasket, thickening flat gasket, spring washer, nut are formed.
During use, be installed in the feeder below, substitute original floating type isolation spring, the upper end is connected with the feeder bottom with bolt, and the lower end is connected with the feeder support with bolt.
During the utility model work, the isolation spring of two ends collapsed shape is when playing the vibration reduction and cushioning effect, because both ends of the spring is bolt, avoided isolation spring and feeder and feeder support because of the noise that the vibration bump produces, the vibration noise when effectively reducing the feeder operation.
The utility model has the advantages that simple in structurely, noise reduction is obvious, compares with existing floating type isolation spring, can reduce noise 30-40 decibel.
Description of drawings
Fig. 1 is a feeder noise-decreasing device scheme drawing.
Fig. 2 is the local enlarged diagram of feeder noise-decreasing device.
Among the figure: 1. feeder, the 2. isolation spring of two ends collapsed shape, 3. feeder support, 4. bolt, 5. flat gasket, 6. thickening flat gasket, 7. spring washer, 8. nut
The specific embodiment
Referring to Fig. 1 and Fig. 2, the feeder noise-decreasing device by the isolation spring 2 of two ends collapsed shape, with feeder and feeder support bonded assembly bolt 4, and flat gasket 5, thickening flat gasket 6, spring washer 7, nut 8 are formed.Because isolation spring 2 two ends of two ends collapsed shape are all fixed by bolt 4, avoided the isolation spring 2 of two ends collapsed shape and feeder 1 and feeder support 3 to clash into the noise that produces because of vibration.
Claims (1)
