Embodiment 1: as shown in Figure 1 and Figure 2, a kind of micro-blasting device inside lumber, comprise the piston cylinder 2 that is connected in series be used to the high pressure cylinder 1 that holds timber, with this high pressure cylinder 1, between high pressure cylinder 1 and piston cylinder 2, be fixed with dividing plate 3, offer the relief hole 30 that is communicated with high pressure cylinder 1 and piston cylinder 2 on this dividing plate 3; Offer the steam vent 20 that is in communication with the outside on the cylinder wall that this piston cylinder 2 and dividing plate 3 close on, be provided with the piston 4 that to support and to seal relief hole 30 in this piston cylinder 2, be provided with the guide rod 7 that guiding piston 4 moves in the piston cylinder 2, the two ends of guide rod 7 are spirally connected with piston cylinder end cap 9 and dividing plate 3 respectively, guide rod 7 can make piston 4 more steady in motion process, reduce the friction of piston 4 and piston cylinder 2 side arms, prolong the service life of piston 4, in order to reach best effect, the quantity of guide rod 7 has two or three, along circumferentially uniform.The position that guide rod 7 closes on piston cylinder 2 is arranged with buffer spring 8, and when pressure release, piston 4 impulsive force to the right is larger, and buffer spring 8 can make piston 4 impulsive force to the right obtain buffering, and the impact force of reduction and end cap 9 prolongs the service life of piston.
It is the inclined-plane that piston 4 seals the face that contacts mutually with relief hole 30, the angle of inclination on inclined-plane can be between 5 ° to 85 °, after gases at high pressure enter piston cylinder 2 from air inlet 21 like this, can make piston 4 by the inclined-plane compression relief hole 30 tightly of contact, realize reliably sealing, make high-pressure act on the timber fully, improve its demolition effect and blasting efficiency, for the sealing after making piston 4 and relief hole 30 contacting more firm, piston 4 mutually seals on the face that contacts with relief hole 30 and is fixed with sealing gasket 6, in addition, sealing gasket 6 also can play cushioning effect with contacting of relief hole 30 to piston 4.Offer air inlet 21 on the end cap of piston cylinder 2, gases at high pressure are filled with from air inlet 21 during work.
Piston 4 is positioned at piston cylinder 2, comprises integrated sealing plate 41 and piston plate 42, and relief hole 30 can be supported and seal to sealing plate 41 radial dimensions also less than the radial dimension of piston plate 42; Support and seal relief hole 30 states at sealing plate 41, this piston plate 42 is dodged steam vent 20 and is formed annular seal space with piston cylinder 2 end caps.Piston 4 is provided with the air inlet pipe 40 of the connection high pressure cylinder 1 that runs through and piston cylinder 2, is provided with check valve 5 in this air inlet pipe 40, and this check valve 5 makes gas unidirectional enter high pressure cylinder 1, and check valve 5 has guaranteed that the gases at high pressure that enter in the high pressure cylinder 1 can not run out of along air inlet pipe 40.
Embodiment 2: present embodiment only is that from the difference of embodiment 1 structure of piston 4 is different, as shown in Figure 3, Figure 4, the piston 4 of present embodiment is positioned at piston cylinder 2, comprise sealing plate 41 and piston plate 42, sealing plate 41 and piston plate 42 link into an integrated entity by bolt 7, such connection can conveniently be processed and load and unload, and relatively saves simultaneously material.Relief hole 30 can be supported and seal to sealing plate 41 radial dimensions also less than the radial dimension of piston plate 42; Support and seal relief hole 30 states at sealing plate 41, this piston plate 42 is dodged steam vent 20 and is formed annular seal space with piston cylinder 2 end caps.Equally, can be provided with the air inlet pipe 40 of the connection high pressure cylinder 1 that runs through and piston cylinder 2 on the piston 4, be provided with check valve 5 in this air inlet pipe 40, this check valve 5 makes gas unidirectional enter high pressure cylinder 1, and check valve 5 has guaranteed to enter high pressure cylinder 1 interior gases at high pressure and can not run out of along air inlet pipe 40.
Course of work embodiment 1 of the present utility model is identical with embodiment 2, and the below describes in detail as an example of embodiment 1 example, referring to Fig. 1 and Fig. 2:
As shown in Figure 1: will need the timber of explosion to put into high pressure cylinder 1, when carrying out explosion, gases at high pressure are filled with from air inlet 21, pushing piston 4 is to left movement, until with relief hole 30 close contacts, firmly compress relief hole 30 by the inclined-plane, the high pressure cylinder 1 at timber place is disconnected with steam vent 20, pressed gas enters in the high pressure cylinder 1 from air inlet pipe 40 afterwards, until the pressure of demolition set inside reaches balance, the air pressure of piston 4 both sides equates that because air inlet pipe 40 is provided with check valve 5, gases at high pressure can only enter and can not run out of from air admission hole 40 from air inlet pipe 40.Because sealing plate 41 radial dimensions of piston 4 are less than the radial dimension of piston plate 42, so piston 4 both sides lifting surface areas do not wait, the lifting surface area of piston plate 42 is greater than the lifting surface area of sealing plate 41, make piston 4 this moment suffered active force to the right less than active force left, produce making a concerted effort left, piston 4 is pressed on the relief hole 30 tightly.Timber bears the effect of gases at high pressure in high pressure cylinder 1, make its internal pressure and external pressure balance.
As shown in Figure 2: when the needs quick pressure releasing, gases at high pressure are got rid of from the air inlet 21 on piston 4 right sides, pressure in the piston cylinder 2 descends rapidly, make the suffered pressure in piston 4 right sides rapidly less than the suffered pressure in left side, cause piston 4 along knife bar 7 rapidly, move right stably, buffer spring 8 available buffer pistons 4 impulsive force to the right, reduce the impact force with end cap 9, relief hole 30 is opened simultaneously, gas in the high pressure cylinder 1 is discharged from steam vent 20 fast, the high pressure cylinder internal pressure sharply descends, and timber internal pressure gas is realized explosion rapidly to external diffusion.
To sum up, the utility model can make piston more steady in motion process when guaranteeing that demolition set is easy and simple to handle, cost is low, having these advantages of good demolition effect, reduces the friction of piston and piston cylinder side arm, the service life of prolongation piston.
