Description

호퍼(hopper)에 있어서의 피수용물의 잔량(殘量) 검출장치Apparatus for detecting residual amount of water to be contained in hopper

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제 1 도는 본 발명의 잔량 검출장치를 적용한 옆줄에 비료주는 장치의 호퍼를 표시하는 정면도.1 is a front view showing the hopper of the fertilizer giving device on the side line to which the residual amount detection device of the present invention is applied.

제 2 도는 동 호퍼의 종단측면도.2 is a longitudinal side view of the hopper.

제 8 도는 잔량 검출장치의 블록도.8 is a block diagram of a residual amount detection device.

*도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

4 : 호퍼 5 : 잔량 검출센서4: Hopper 5: remaining amount detection sensor

51 : 광전셀51: photoelectric cell

Claims (1)

호퍼(4)에 있어서의 아래부분위치에 복수의 광전셀(51)을 복수개 옆방향으로 나란히 설치한 태양전지로서 이루어지는 잔량 검출센서(5)를, 상기한 광전셀(51)의 나란히 설치한 방향이 대략 수평방향으로 되도록 첨가하여 설치한 것을 특징으로 하는 호퍼에 있어서의 피수용물의 잔량 검출장치.The direction in which the remaining amount detection sensor 5 formed as a solar cell in which a plurality of photovoltaic cells 51 are arranged side by side in a lateral direction in the hopper 4 is provided side by side of the photoelectric cells 51. The residual amount detection apparatus of the to-be-retained object in the hopper characterized by adding so that it may become substantially horizontal direction. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
