본 고안은 단단한 토양이나 지반에서 작업을 할 경우 버켓이 주기적으로 맥동현상이 일어나도록하여 작업효율을 증대시킨 굴삭기의 맥동굴삭작업장치에 관한 것이다.The present invention relates to a pulsating excavator working device of the excavator to increase the work efficiency by pulsating the bucket periodically when working on hard soil or ground.
좀더 구체적으로는 메인콘트롤 밸브를 작동시키는 파일롯트 유압라인에 주기적으로 파일롯트 오일의 흐름을 전환시키는 솔레노이드밸브를 설치하여 메인콘트롤 밸브로부터 버켓실린더로 공급되는 오일을 주기적으로 변환시키도록 함으로서 버켓이 굴삭작업을 할 경우 순간순간 지면에 충격을 가하면서 작업이 되도록 하여 지면이 단단하더라도 작업이 용이하도록 한 것에 관한 것이다.More specifically, a bucket is excavated by installing a solenoid valve that periodically changes the flow of pilot oil in the pilot hydraulic line that operates the main control valve to periodically change the oil supplied from the main control valve to the bucket cylinder. When working, the moment to impact the ground to make the work so that even if the ground is hard to facilitate the work.
종래의 굴삭기의 굴삭작업장치는 제1도에 도시한 바와같이 메인펌프(1)에는 MCV(4)를 연결하고, 상기 MCV(4)에는 버켓실린더(5)를 연결하되, 상기 MCV(4)를 파일롯트펌프(2)에 연결된 RCV(3)에 의해 이루어지도록 구성되어 있었다.Excavator working device of the prior art as shown in Figure 1 is connected to the main pump (1) MCV (4), the MCV (4) is connected to the bucket cylinder (5), the MCV (4) It was configured to be made by RCV (3) connected to the pilot pump (2).
즉, 종래의 굴삭기는 RCV(3)레버를 작동시키면 파일롯트펌프(2)의 유압이 RCV(3)를 지나 MCV(4)를 작동시키게 됨으로써, 메인펌프(1)로 토출되는 오일이 MCV(4)의 작동에 따라 버켓실린더(5)의 피스톤로드를 전진시키거나 후진시키게 되어 있었다.That is, when the conventional excavator operates the RCV (3) lever, the hydraulic pressure of the pilot pump (2) passes the RCV (3) to operate the MCV (4), so that the oil discharged to the main pump (1) MCV ( According to the operation of 4), the piston rod of the bucket cylinder 5 was advanced or retracted.
따라서, 굴삭작업을 할 경우에는 MCV(4)를 좌측방향으로 이동시켜 버켓실린더(5)의 후면으로 오일이 공급되도록 하여 피스톤로드를 전진시키도록만 되어 있었기 때문에 단단한 토양에서 작업을 할 경우 작업에 어려움이 많았다.Therefore, when the excavation work is to move the MCV (4) to the left direction so that the oil is supplied to the rear of the bucket cylinder (5) to advance the piston rod to work when working on hard soil There was a lot of difficulty.
본 고안은 상기와 같은 결점을 제거하기 위하여 안출된 것으로서, 릴레이와 타이머(TIMER), 솔레노이드밸브에 의하여 버켓실린더의 MCV를 주기적으로 반복하여 구동시키게 하여 버켓실린더 브래커(BREAKER)처럼 연속적으로 전, 후진하게 함으로써 단단한 토양이나 지반에서 굴삭작업 할때 작업의 효율을 높이고, 손실을 방지하도록 하는데 고안의 목적이 있다.The present invention has been devised to eliminate the above drawbacks, and the relay, timer (TIMER), solenoid valve to periodically drive the MCV of the bucket cylinder repeatedly, like the bucket cylinder breaker (BREAKER) By reversing, the purpose of the design is to increase the efficiency of work and to prevent the loss when digging in hard soil or ground.
상기 목적을 달성하기 위한 본 고안의 특징은, 파이롯트 펌프와 RCV사이에 솔레노이드밸브 A를 연결하고, 상기솔레노이드밸브 A에는 또다른 솔레노이드밸브 B를 연결하여 오일의 유로를 개폐되도록 하고, 상기 솔레노이드밸브 A는 온/오프 스위치에 의해 작동되도록 전원에 연결하고, 상기 솔레노이드밸브 B는 온/오프 스위치, 릴레이 및 타이머에 의해 주기적으로 작동되도록 전원에 연결한 구조로 된 것으로서, 이하 첨부된 도면에 의거하여 본 고안의 구성을 상세히 설명하면 다음과 같다.A feature of the present invention for achieving the above object is, connecting the solenoid valve A between the pilot pump and RCV, the solenoid valve A is connected to another solenoid valve B to open and close the oil passage, the solenoid valve A Is connected to a power source to be operated by an on / off switch, and the solenoid valve B is configured to be connected to a power source to be periodically operated by an on / off switch, a relay, and a timer, according to the accompanying drawings. The configuration of the invention in detail as follows.
제2도에 도시한 바와같이 메인펌프(1)에는 MCV(4)를 연결하고, 상기 MCV(4)에는 버켓실린더(5)를 연결하되, 상기 MCV(4)를 파일롯트펌프(2)에 연결된 RCV(3)에 의해 이루어지도록 구성된 통상의 굴삭작업장치에 있어서, 파일롯트 펌프와 RCV사이에 솔레노이드밸브 A(6)을 연결하고, 상기 솔레노이드밸브 A(6)에는 또다른 솔레노이드밸브 B(9)를 연결하여 오일의 유료를 개폐되도록 하고, 상기 솔레노이드밸브 A(6)는 오/오프스위치(7)에 의해 작동되도록 전원(11)에 연결하고 상기 솔레노이드밸브 B(9)는 온/오프스위치(7), 릴레이(10) 및 타이머(8)에 의해 주기적으로 작동되도록 전원(11)에 연결한 구조로 된 것이다.As shown in FIG. 2, an MCV 4 is connected to the main pump 1, and a bucket cylinder 5 is connected to the MCV 4, but the MCV 4 is connected to the pilot pump 2. In a conventional excavating work device configured to be connected by a connected RCV (3), a solenoid valve A (6) is connected between the pilot pump and the RCV, and another solenoid valve B (9) is connected to the solenoid valve A (6). The solenoid valve A (6) is connected to the power supply 11 to be operated by the on / off switch (7), and the solenoid valve B (9) is on / off switch. (7), the structure is connected to the power supply 11 to be periodically operated by the relay 10 and the timer (8).
즉, 상기 전원(11)의 일단에는 솔레노이드밸브 A,B(6, 9)를 연결하고, 전원의 타단에는 온/오프스위치(7)를 연결한 후, 상기 솔레노이드밸브 A(6)는 온/오프스위치(7)의 작동에 따라 곧바로 작동되도록 연결하고, 상기 솔레노이드밸브 B(9)는 타이머(8) 및 릴레이 (8)에 의해 작동되도록 연결을 한다.That is, the solenoid valves A, B (6, 9) are connected to one end of the power supply 11, and the on / off switch 7 is connected to the other end of the power source, and the solenoid valve A 6 is turned on / off. It is connected to operate immediately according to the operation of the off switch (7), the solenoid valve B (9) is connected to be operated by the timer (8) and the relay (8).
상기와 같이 구성된 본 고안의 작용효과를 성명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
제2도에 도시된 바와같이 온/오프 스위치(7)를 ON시키면 솔레노이드밸브 A(6)가 작동하여 파이롯트펌프(2)의 유압이 RCV(3)에서솔레노이드밸브 B(9)로 절환되고, 동시에 릴레이(10)가 ON상태로 되므로 타이머(8)가 설정된 시간동안 주기적으로 ON-OFF되게 한다.As shown in FIG. 2, when the on / off switch 7 is turned on, the solenoid valve A 6 is operated to switch the hydraulic pressure of the pilot pump 2 from the RCV 3 to the solenoid valve B 9, At the same time, since the relay 10 is turned on, the timer 8 is periodically turned on and off for a set time.
타이머(8)가 ON되면 솔레노이드밸브(9)가 작동하여 파이롯트펌프(2)의 유압이 MCV(4)를 지나 버켓실린더(5)에 공급되어 버켓실린더(5)가 인(IN)되고, 타이머(8)가 OFF상태로 되면, 솔레노이드 밸브 B(9)가 작동되지 않아 파일롯트펌프(2)의 유압이 MCV(4)를 반대로 작동시켜, 메인펌프(1)의 유압이 MCV(4)를 지나 버켓실린더(5)에 공급되어 버켓실린더가 아웃(OUT)된다. 그러므로, 타이머(8)의 설정시간에 따라 솔레노이드밸브 B(9)와 MCV(4)가 주기적으로 연속하여 인-아웃이 반복 작동하게 된다. 그러나, 온/오프스위치(7)를 OFF시키면 파일롯트펌프(2)의 유압이 정상적으로 RCV(3)로 공급되고, 릴레이(10)가 OFF상태가 되어 타이머(8)가 작동하지 않게 되어서 RCV레바를 조작하는데로 버켓실린더가 움직이게 된다.When the timer 8 is turned on, the solenoid valve 9 is operated so that the hydraulic pressure of the pilot pump 2 is supplied to the bucket cylinder 5 through the MCV 4 so that the bucket cylinder 5 is IN. When (8) is turned OFF, the solenoid valve B (9) is not operated so that the hydraulic pressure of the pilot pump (2) operates the MCV (4) in reverse, and the hydraulic pressure of the main pump (1) causes the MCV (4) to operate. Gina is supplied to the bucket cylinder (5), the bucket cylinder is out (OUT). Therefore, according to the set time of the timer 8, the solenoid valve B 9 and the MCV 4 periodically and continuously perform in-out repeatedly. However, when the on / off switch 7 is turned off, the hydraulic pressure of the pilot pump 2 is normally supplied to the RCV 3, the relay 10 is turned off, and the timer 8 is not operated so that the RCV lever The bucket cylinder is moved to operate.
상기와 같은 본 고안은 온/오프스위치와 릴레이, 타이머, 솔레노이드밸브 A, B에 의해서 MCV와 버켓실린더를 브래커처럼 주기적으로 연속하여 작동시켜 단단한 토양이나 지반을 굴삭할 때 사용하므로써, 굴삭작업의 효율을 증대시켜 손실을 방지할 수 있는 효과가 있는 것이다.The present invention as described above is used to excavate hard soil or ground by operating the MCV and the bucket cylinder periodically and continuously by the on / off switch, relay, timer, solenoid valve A, B like a breaker, The effect is to prevent the loss by increasing the efficiency.
