Description
Technical field：
The invention belongs to pneumatics field, more particularly to a kind of Pneumatic knocking hammer.
Background technology：
Feed bin can adhere to many dust after long-time use, influence normally to produce, and one kind is needed quickly and easily to remove
Dirt device removes the dust adhered on feed bin, ensures normal production.
Being disclosed in the information of the background technology part, it is only intended to increase understanding of the overall background of the invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or imply that the information is constituted in any form.
Invention content：
The purpose of the present invention is to provide a kind of Pneumatic knocking hammers, to overcome above-mentioned defect in the prior art.
To achieve the above object, the present invention provides a kind of Pneumatic knocking hammers, including cylinder head, substrate, permanent magnet, work
Plug, cylinder, spring, gas source connector；The cylinder head is connect with cylinder, and the substrate is arranged between cylinder head and cylinder, institute
It states and is provided with permanent magnet on substrate, the piston is arranged in cylinder and is sleeved on permanent magnet, and bullet is set on the piston
Spring, between piston and tail cylinder, the cylinder tail end is connected to the spring overhead with feed bin；It is provided at the top of the cylinder head
Gas source connector, the cylinder head inner hollow form atmospheric pressure cavity, stomata are provided in the middle part of the substrate, and substrate is not contacted with piston,
Gas applies pressure by the gas passage of atmospheric pressure cavity-stomatal limiting value to piston, by the variation of air pressure in atmospheric pressure cavity, changes gas
The magnitude relationship of pressure and magnetic force controls piston up-down, taps feed bin.
Compared with prior art, the present invention has the advantages that：
Pneumatic knocking hammer controls piston motion by the variation of air pressure, taps feed bin repeatedly and shoots down dust, simple and fast
Feed bin is cleared up, ensure that being normally carried out for production.
Description of the drawings：
Fig. 1 is Pneumatic knocking hammer structural schematic diagram of the present invention；
Reference numeral is：1- cylinder head, 2- substrates, 3- permanent magnets, 4- pistons, 5- cylinders, 6- springs, 7- gas source connectors,
8- atmospheric pressure cavities, 9- stomatas.
Specific implementation mode：
The specific implementation mode of the present invention is described in detail below, it is to be understood that protection scope of the present invention is not
It is restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
As shown in Figure 1, a kind of Pneumatic knocking hammer, including cylinder head 1, substrate 2, permanent magnet 3, piston 4, cylinder 5, spring 6,
Gas source connector 7；The cylinder head 1 is connect with cylinder 5 by trip bolt, spring washer, is sealed by sealing ring, the substrate
2 are arranged between cylinder head 1 and cylinder 5, permanent magnet 3 are provided on the substrate 2, the setting of the piston 4 is in cylinder 5 and covers
On permanent magnet 3, is sealed by piston ring, sealing ring between piston 4 and cylinder 5, spring 6 is set on the piston 4, it is described
Between 5 tail portion of piston 4 and cylinder, 5 tail end of the cylinder is connected to 6 overhead of spring with feed bin；1 top of the cylinder head is provided with gas
Source connector 7,1 inner hollow of the cylinder head form atmospheric pressure cavity 8, and 2 middle part of the substrate is provided with stomata 9, and substrate 2 and piston 4 are not
Contact, gas apply pressure to piston 4 by the gas passage that atmospheric pressure cavity 8- stomatas 9 are formed, pass through the change of air pressure in atmospheric pressure cavity 8
Change, change the magnitude relationship of air pressure and magnetic force, control piston 4 moves up and down, and taps feed bin.
In the state of not being passed through compressed air, magnetic piston 4 is close to be fixed on permanent magnet 3 by strong magnetic force.Three
Three-way electromagnetic valve be powered when, compressed air by gas source connector 7 flow into atmospheric pressure cavity 8 in, the pressure in atmospheric pressure cavity 8 increases, when more than
When magnetic force, magnetic piston 4 is detached from a high speed permanent magnet 3, since the reaction force of strong magnetic force generates very strong counterforce, falls at a high speed
Magnetic piston 4 hit pedestal, impact force is transmitted to feed bin, and the dust of attachment is shot down with strong impact force.Threeway electromagnetism
When valve stops being powered, the compressed air in atmospheric pressure cavity 8 is discharged by gas source connector 7, then by return spring 6 by magnetic piston
4 slowly rise again close to permanent magnet 3, are closely contacted on permanent magnet 3 by magnetic force, are returned to original state.
The description of the aforementioned specific exemplary embodiment to the present invention is in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can much be changed
And variation.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the present invention and its actually answering
With so that those skilled in the art can realize and utilize the present invention a variety of different exemplary implementation schemes and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
