FIELD: agriculture.SUBSTANCE: invention relates to agriculture, in particular to devices for the studying water erosion, and can be used in soil science, amelioration and hydrology. The profile recorder for determining the slope of the elementary area in the field comprises a frame with three supports. In the centre of the frame a pivotally-fixed axis is located vertically, provided with a rolling bearing, on which the telescopic arm is located with a vertical rack fixed on the end, in the lower part of which a leash in the form of a parallelogram is attached, as well as the roller and a mechanism of reading the vertical movement of the roller. The reading mechanism consists of a sensor of movement, a rigid belt with a longitudinal frame, a guide mounted on the bracket, and a movement sensor. The information from the movement sensor is transmitted to the computer through the radio frequency communication.EFFECT: technical result of the invention is to simplify the method and to improve the accuracy of determining the average slope of the elementary area in the field.2 cl, 7 dwg |
