Description
УСТРОЙСТВО дл ОБНАРУЖЕНИЯ РАСТЕНИЙ НА ПОЧВЕDEVICE FOR DETECTING PLANTS ON SOIL
II
Изобретение относитс к сельскому хоз йст1ву и предназначено дл автоматизации межйур. обработки, прорежи1ва,ни и уборки сельокохоз Й€твеннЫ(Х культур.The invention relates to agriculture and is intended to automate interrai. processing, cutting, and harvesting of agricultural farms.
Известны устройства дл обнаружени растений на почве, содержащие высокочастотный генератор и емкостный чувствительный элемент.Devices for detecting plants on the soil are known, comprising a high frequency generator and a capacitive sensing element.
Однако эти устройства имеют небольшую точность определени центра растени (о;собенло дл раз;ветвленных растений) и оси р дка растений из-за малой глубины чувствительной зоны SMiKOCTHbix чувствительных элементав, а также из-за различной нестабильности , включелных «а Вход схемы сравнени .However, these devices have little accuracy in determining the center of the plant (o; assembled for times; branched plants) and the axis of a row of plants due to the small depth of the sensitive area of the SMiKOCTHbix sensitive elements, as well as due to the different instabilities included in the Comparison Input.
Цель изобретени - повышение точности определени оси р дка li центра растений.The purpose of the invention is to improve the accuracy of determining the axis of the row li of the center of plants.
Это достИГаетс тем, что чувствительные элементы устройства выполнены в виде «ескОоТьких взаимоов занНЫх колебательных контуров, один из которых возбуждаетс от стабилизированного генератора, а остальные, симметрично ра-оположенные относительно оси р щка растений, подсоединеды к балансной из1мер.итель«ой схеме.This is achieved by the fact that the sensing elements of the device are made in the form of “SEQUENTIAL interconnected oscillatory circuits, one of which is excited from a stabilized generator, and the rest, symmetrically distributed relative to the axis of the plants' pitch, are connected to a balanced one-dimensional source”.

The oscillatory circuits 5 and 6 are enclosed in screens 7 and 8 and CBSsawbi with antenna element 4 through the high-frequency electromagnetic field of the sensitive zone with the help of antenna sensor elements 9 and 10 of capacitive type. Oscillatory Circuits 5 and (J are equipped with frequency add-on mechanisms, for example, with a change in capacitance.
