And an overload detecting portion interfering member 34 that selectively interferes with the branch 40.

적재물간섭부재(32)는 적재물(10)에 접하면서 상측으로 밀리는 기술사상 안에서 판 형상을 포함한 다양한 형상으로 형성된다.The load interference member 32 is formed in various shapes including a plate shape in the technical concept of being pushed upward while contacting the load 10.

적재물간섭부재(32)에서 상측으로 연장된 과적재감지부간섭부재(34)는 적재 물간섭부재(32)와 같이 상측으로 이동되면서 과적재감지부(40)를 동작시키는 기술사상 안에서 봉 형상을 포함한 다양한 형상으로 형성된다.The overload detecting portion interfering member 34 extending upward from the load interfering member 32 moves upwards like the load interfering member 32 and includes various rod shapes in the technical concept of operating the overload detecting portion 40. It is formed into a shape.

과적재감지부간섭부재(34)가 이동가능하게 설치되는 고정부재(50)는 굴삭부(3)에 고정 설치된다. 고정부재(50)는 판 형상으로 형성되며, 프레임부(7)에 일측이 고정되어 굴삭부(3)의 측방향으로 돌출 형성된다.The fixing member 50 to which the overload detecting part interfering member 34 is movable is fixed to the excavation part 3. Fixing member 50 is formed in a plate shape, one side is fixed to the frame portion 7 is formed to protrude in the lateral direction of the excavation (3).

고정부재(50)를 관통하며 과적재감지부간섭부재(34)가 설치되므로 과적재감지부간섭부재(34)는 상하로 슬라이딩 가능하게 설치된다.Since the overload sensing portion interference member 34 is installed through the fixing member 50, the overload sensing portion interference member 34 is installed to be slidable up and down.

과적재감지부간섭부재(34)의 상측에는 걸림부재(36)가 돌출 형성되며, 걸림부재(36)가 고정부재(50)에 걸려서 과적재감지부간섭부재(34)의 하측 이탈을 방지한다.The locking member 36 protrudes from the upper side of the overload detecting part interfering member 34, and the locking member 36 is caught by the fixing member 50 to prevent the overload detecting part interfering member 34 from falling down.

과적재감지부(40)는 고정부재(50)에 설치되며, 과적재감지부간섭부재(34)의 상측 이동으로 작동된다.Overload detection unit 40 is installed on the fixing member 50, it is operated by the upward movement of the overload detection unit interference member 34.

이하에서는 첨부된 도면들을 참조하여 본 발명의 일 실시예에 따른 연속식 하역장치(1)의 작동상태를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the operating state of the continuous unloading device 1 according to an embodiment of the present invention.

굴삭부(3)가 적재물(10)이 있는 방향으로 하강하여 굴삭부(3)가 적재물(10)에 접한 상태에서 이동부(5)를 회전시키므로 버킷(6)에 적재물(10)을 적재하여 외측으로 이송한다.As the excavation part 3 descends in the direction of the load 10 and the excavation part 3 rotates the moving part 5 while the excavation part 3 is in contact with the load 10, the load 10 is loaded in the bucket 6. Transfer it to the outside.

굴삭부(3)가 설정된 깊이 이상으로 적재물(10)에 파묻히는 경우, 적재물간섭 부재(32)는 적재물(10)에 접하여 상측으로 가압되며, 탄성부재(60)의 가압력 보다 적재물(10)과 접하여 발생된 가압력이 큰 경우에는 적재물간섭부재(32)와 같이 과적재감지부간섭부재(34)도 상측으로 이동한다.When the excavation part 3 is buried in the load 10 beyond the set depth, the load interference member 32 is pressed upwards in contact with the load 10, and the load 10 and the pressing force of the elastic member 60 and When the force generated by contact is large, the overload detecting portion interfering member 34 also moves upward, like the load interfering member 32.

과적재감지부간섭부재(34)가 상측으로 이동하면서 과적재감지부(40)를 작동시키므로, 과적재감지부(40)는 제어부로 감지신호를 전송하여 굴삭부(3)의 하측 이동을 정지시킨다.Since the overload detecting unit interference member 34 moves upward, the overload detecting unit 40 operates, and the overload detecting unit 40 transmits a detection signal to the control unit to stop the downward movement of the excavator 3.

굴삭부(3)가 상승되어 설정된 깊이로 적재물(10)에 묻히면 탄성부재(60)의 탄성력으로 적재물간섭부재(32)와 과적재감지부간섭부재(34)가 하측으로 이동하면서, 과적재감지부간섭부재(34)는 과적재감지부(40)를 간섭하지 않는다.When the excavation portion 3 is raised and buried in the load 10 to a set depth, the load interference member 32 and the overload detection portion interference member 34 move downward by the elastic force of the elastic member 60, and the overload detection portion interference. The member 34 does not interfere with the overload detecting unit 40.

굴삭부(3)의 버킷(6)에는 적정량의 적재물(10)만 적재되어 이송되므로 작업 효율성이 향상된다.Since only a proper amount of the load 10 is loaded and transferred to the bucket 6 of the excavation part 3, the work efficiency is improved.

상술한 바와 같은 구성에 의하면, 일 실시예에 따른 연속식 하역장치(1)는, 적재물(10)을 향하여 하강하는 굴삭부(3)가 설정된 깊이 이상으로 적재물(10)에 파묻히면, 과적재방지부(20)가 이를 감지하여 버킷(6)이 적재물(10)을 과적재하는 것을 방지하여 연속식 하역장치(1)의 동작 불량을 감소시킬 수 있으며, 내구성도 향상시킬 수 있다.According to the configuration as described above, the continuous loading and unloading device 1 according to one embodiment, if the excavation portion 3 descending toward the load 10 is buried in the load 10 more than the set depth, overload reload The branch 20 detects this to prevent the bucket 6 from overloading the load 10, thereby reducing the malfunction of the continuous unloading device 1, and improving durability.
