Abstract
A hydraulic breaker, which is an equipment used to break large rocks or any object that is desired to be broken into smaller pieces, and characterized in that; including, - cylinder (100) with at least one hole (102) that allows the pressurized oil (Y) to enter the signal control channel (111) on the piston (110) from the oil inlet (I) side, and whose angle and diameter values can change according to the power and/or size of the hydraulic breaker and - piston (110) having at least one signal control channel (111) with a width greater than the distance betten the lower point of the drain hole (91) and the upper point of the hole (102) to ensure that the piston (110) is not triggered for preventing damage to the tool retainers (140), piston (110) and the cylinder (100) during breaking if there is no object to break in front of the said tool (160), before the impact energy generated through the piston (110) is transferred to the tool (160).
Claims
1. The invention is a hydraulic breaker, which is an equipment used to break large rocks or any object that is desired to be broken into smaller pieces, and characterized in that including: in order to ensure that the piston (110) is not triggered, to prevent the damage to wedges (140), piston (110) and cylinder (100) during crushing if there is no object to break in front of the tip (160), while the impact energy generated through the piston (110) is transferred to the tip (160), o a cylinder (100) with at least one hole (102) that allows the pressure oil (Y) to enter the signal control channel (111) on the piston (110) from the oil inlet (I) side, and whose angle and diameter values can change according to the power and/or size of the hydraulic breaker, o a piston (110) having at least one signal control channel (111) with a width greater than the distance between the lower point of the drain hole (91) and the upper point of the hole (102), a setscrew bolt (170) which does not allow the pressure oil (Y) to pass to the drain line (90) and is placed in the said hole (102) in situations where the feature of not hitting at the idle is not desired to be used.
2. A method for hydraulic breaker, which is an equipment used to break large rocks or any object that is desired to be broken into smaller pieces and characterized in that;
- Moving the pressurized oil (Y) into the system via the oil inlet (I) in the valve housing (20) and the piston (110) moving upwards (S1000),
- Downward movement of the piston (110) with the position change of the main control valve (70) (S2000),
- Piston (110) continuing to move downwards until it hits the tool (160) (S3000),
- Piston (110) hitting the tool (160) with the main control valve (70) changing its position again (S4000),
- Sending the pressurized oil (Y) over the hole (102) to the drain hole (91) in the cylinder (100), from the drain hole (91) to the drain line (90), from the said drain line (90) to the oil outlet (O) and activation of the anti-blank firing feature and stopping the movement of the tool (160), if there is no breakable object in front of the tool (160) (S5000),
- Another breakable piece coming in front of the tool (160), and the tool (160) pushing the piston (110) up and the movement repeating (S6000).

3. A hole (102) mentioned in any one of the above claims and characterized in that; including a blind plug (180) that allows intervention when necessary.
4. A hydraulic breaker mentioned in any one of the above claims, and characterized in that; including an accumulator (10) that enables the pressure resulting from the generation of impact energy to be regenerated again and again.
5. An accumulator (10) mentioned in the Claim 5 and characterized in that; including a diaphragm (11) that separates the nitrogen gas (N) and pressurized oil (Y) from each other, which inflates when necessary and increases the pressure of the oil coming from the excavator and transmits it to the breaker.
6. A hydraulic breaker mentioned in any one of the above claims and characterized in that; some pressurized oil (Y) is transferred to the signal control channel (111) via the hole (102) from the signal control channel (111) to the drain hole (91), from the drain hole (91) to the drain line (90) in order to prevent the diaphragm (11) from contacting the lowest surface of the accumulator (10) after the compressed nitrogen gas (N) creates a pressure explosion when it reaches the breaking point.
7. A hydraulic breaker mentioned in any one of the above claims, and characterized in that; including at least one top buffer on its upper part, which absorbs all mechanical energies and recoil forces and acts as a suspension.
8. A hydraulic breaker mentioned in any one of the above claims, and characterized in that; including at least one bottom buffer (200) to protect the breaker from the vibration that occurs at the time of breaking.
9. A hydraulic breaker mentioned in any one of the above claims, and characterized in that; including a check valve (30) that allows the high- pressure oil (Y) from the excavator to enter the chamber through the oil inlet (I) line.
10. A hydraulic breaker mentioned in any one of the above claims, and characterized in that; including pressurized oil (Y) that passes to the lower part of the cylinder (100) by guiding the valve group and ensures that the
11
pressure of the said lower part is higher than the pressure of the upper part and thus moves the piston (110) upwards.
11. A hydraulic breaker mentioned in any one of the above claims, and characterized in that; including an oil drain line (90) ensuring that the pressurized hydraulic oil (Y) is sent back to the oil outlet (O) while the piston (110) continues to move upwards.
12. A hydraulic breaker mentioned in any one of the above claims, and characterized in that; including nitrogen gas (N) inside the diaphragm (11), which inflates the diaphragm (11) until it reaches the breaking point and applies high pressure to the piston (110) by providing the last pressure explosion.
13. A hydraulic breaker mentioned in any one of the above claims, and characterized in that; including the piston clearance (101) that is located between the cylinder (100) and the piston (110) and allows the piston (110) to move up and down.
