Abstract
The utility model relates to a vibrating feeder secondary vibration damper comprises vibrating feeder, vibrating feeder vibration damper, secondary damping frame, secondary damping spring, secondary damping seat, balanced pad. The anti-resonance principle can well meet the requirements of the system on vibration frequency and amplitude, and can eliminate the influence of slight vibration of the lower mass on the foundation during working, thereby greatly reducing the dynamic load on the foundation, reducing the requirements on the strength and rigidity of the foundation and greatly reducing the foundation civil engineering cost. Meanwhile, the vibrating feeder can run more stably, particularly, when the vibrating feeder is started or stopped, the amplitude is greatly reduced through a resonance point, the vibration is very stable, and the service life of the vibrating feeder can be prolonged. The utility model discloses simple structure, it is sturdy and durable, the large-scale vibration machinery use occasion of each trade such as specially adapted coal, metallurgical mine, chemical industry, building materials, casting, oil, grain.
Description
Technical Field
The utility model relates to a vibrating feeder secondary vibration damper, the large-scale batcher use occasion of each trade such as mainly used coal, metallurgical mine, chemical industry, electric power belongs to vibrating equipment technical field.
Background
At present, the vibrating feeder plays a vital role in material transfer in the wide use of various industries such as coal, metallurgical mines, chemical industry, electric power and the like in China. Along with the development of science and technology, the development of the high-efficiency and high-yield direction becomes the development direction of the vibrating feeder, the vibrating feeder is increasingly large-sized, the requirements on the rigidity and the strength of an equipment installation foundation are increased, the civil engineering cost is greatly increased, especially when some old production lines need to modify equipment to large-scale equipment with high yield, the original old foundation cannot meet the use requirements of a system on vibration frequency and amplitude, the replacement foundation is limited by space and the like, in addition, if the foundation is replaced, the investment is greatly increased, and therefore the secondary vibration reduction technology is a necessary solution.
Disclosure of Invention
For adapting to mine needs, solve not enough among the above prior art, the utility model aims at providing a vibrating feeder secondary damping device.
In order to achieve the above object, the present invention provides a technical solution for solving the technical problem: a secondary vibration damping device of a vibrating feeder comprises the vibrating feeder, the vibration damping device of the vibrating feeder, a secondary vibration damping frame, a secondary vibration damping spring, a secondary vibration damping seat and a balance pad. The technical characteristics are as follows: the vibration feeder 1 carries out primary vibration reduction through the vibration feeder vibration reducing device 2, the lower surface of the vibration feeder vibration reducing device 2 is connected with the upper surface of the secondary vibration reducing frame 3, the lower end of the secondary vibration reducing frame 3 is connected with the upper end of the secondary vibration reducing damping spring 4, the lower end of the secondary vibration reducing damping spring 4 is arranged on the secondary spring seat 5, and the balance pad 6 is arranged between the secondary vibration reducing frame 3 and the secondary vibration reducing seat 5.
Compared with the prior art, the utility model has the following characteristics.
1. Compared with the prior art, the utility model, the antiresonance principle of utilization can satisfy the system well to the requirement of vibration frequency, amplitude to can eliminate the slight vibration of plastid below the during operation to the influence of ground, greatly reduced the dynamic load to the basis, reduce intensity and rigidity requirement to the basis, the basic civil engineering cost that significantly reduces. Meanwhile, the vibrating feeder can run more stably, particularly, when the vibrating feeder is started or stopped, the amplitude is greatly reduced through a resonance point, the vibration is very stable, and the service life of the vibrating feeder can be prolonged.
2. Compared with the prior art, the utility model the balance pad of adoption in the secondary damping is its innovation point, and the damping frame slope that different atresss caused around effectively solving equipment to the noise generation has been avoided.
3. The utility model discloses, large-scale batcher use occasion is used and is all particularly suitable for.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a left side view of fig. 1.
In the figure: 1-2-3-4-5-6-balance pad.
Detailed Description
Embodiments of the present invention are further described below with reference to the accompanying drawings.
Referring to fig. 1-2, the secondary vibration damping device of the vibrating feeder comprises a vibrating feeder, a vibration damping device of the vibrating feeder, a secondary vibration damping frame, a secondary vibration damping spring, a secondary vibration damping seat and a balance pad. The technical characteristics are as follows: the vibration feeder 1 carries out primary vibration reduction through the vibration feeder vibration reducing device 2, the lower surface of the vibration feeder vibration reducing device 2 is connected with the upper surface of the secondary vibration reducing frame 3, the lower end of the secondary vibration reducing frame 3 is connected with the upper end of the secondary vibration reducing damping spring 4, the lower end of the secondary vibration reducing damping spring 4 is arranged on the secondary spring seat 5, and the balance pad 6 is arranged between the secondary vibration reducing frame 3 and the secondary vibration reducing seat 5.
The utility model discloses vibrating feeder secondary vibration damper's theory of operation is: when the vibration reduction device of the vibrating feeder operates in primary vibration reduction, in order to well meet the requirements of a system on vibration frequency and amplitude, the secondary vibration reduction device is formed by the secondary vibration reduction spring and the secondary vibration reduction seat below the secondary vibration reduction frame to carry out secondary vibration reduction, and the phenomenon of noise caused by unbalanced stress is effectively solved by utilizing a balance cushion between the secondary vibration reduction frame and the secondary vibration reduction seat.
Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present invention.
Various modifications and alterations of this invention may be made by those skilled in the art without departing from the spirit and scope of this invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
