Description
Technical field
The present invention relates to vibration screening machinery technical field, be specifically related to auto-excitation type screen cleaning device.
Background technology
Existing vibratory sieve is in the process of screening materials carrying, and owing to existing, material feed is uneven, the humidity of material is uneven, and material very easily produces windrow and plug-hole phenomenon on compass screen surface.Because vibratory sieve works under more stable vibration force closes amplitude effect, when there is windrow or plug-hole phenomenon, be difficult to recover voluntarily; often need to shut down the clear hole process of laggard pedestrian's work; not only cleaning efficiency is low, and labor strength is large, and directly affects the normal screening operation of vibratory sieve.Now drive cleaning plant to produce forced vibration by vibration source in the art, reach the object of cleaning.But adopt above-mentioned measure, need separately to connect power supply, structure is more complicated, and reliability is relatively weak.
Summary of the invention
The object of this invention is to provide a kind of reasonable in design, structure simple, utilize the vibratory sieve kinetic energy that provides of reciprocating vibration and supporting flexible member forms resonator system with vibration sieve nest, thus reach and sieve and the auto-excitation type screen cleaning device of sieve aperture self-cleaning object.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: auto-excitation type screen cleaning device, comprise connecting rod, weight and flexible member, one end of described connecting rod arranges weight, the other end of described connecting rod is connected by support with sieve nest and passes through to impact arm and is connected with screen cloth, and described flexible member is socketed on connecting rod.
Further, described flexible member is for shearing India-rubber spring.
The present invention has following beneficial effect: auto-excitation type screen cleaning device of the present invention, comprise connecting rod, weight and flexible member, wherein, one end of connecting rod arranges weight, the other end is connected by support with sieve nest and passes through to impact arm and is connected with screen cloth, and flexible member is socketed on connecting rod; The present invention adopts said structure, the vibratory sieve kinetic energy provided of reciprocating vibration is provided, supporting flexible member, form a resonator system with vibration sieve nest, thus reach screening and sieve aperture self-cleaning object, compared with traditional cleaning plant, without the need to separately connecing power supply, easy to use, reliability is relatively strong, and cleaning effect is good.In addition, the present invention has the features such as reasonable in design, structure simple, reduce costs, and is mainly used in the screening of fines, can be widely used in the enterprise such as chemical industry, mine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
As shown in Figure 1 and Figure 2, auto-excitation type screen cleaning device, comprises connecting rod 1, weight 2 and flexible member 3, and one end of described connecting rod 1 arranges weight 2, the other end of described connecting rod 1 is connected by support 4 with sieve nest 5 and passes through to impact arm 6 and is connected with screen cloth 7, and described flexible member 3 is socketed on connecting rod 1.Wherein, described flexible member 3 is for shearing India-rubber spring.In the present embodiment, the vibratory sieve kinetic energy provided of reciprocating vibration is provided, supporting flexible member, a resonator system is formed with vibration sieve nest, with self natural frequency vibration, again by linkage by vibration passing to screen cloth, make screen cloth produce the motion of superposition of two kinds of different frequencies, various amplitude, thus reach the object of screening and sieve aperture self-cleaning.In the present embodiment, not only cleaning effect is good to utilize this cleaning plant, and reliability is relatively strong.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, other amendments that those of ordinary skill in the art make technical scheme of the present invention or equivalently to replace, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of right of the present invention.
