A calibration device for the monitoring area of ​​the test field with elastic clamping

Abstract

The invention relates to an elastically clamped device for labelling a monitoring area of a test field in the technical field of agriculture tools. The device comprises a transverse rod; two ends of the transverse rod are vertically connected to vertical rods; a guide hole extending towards the lower end is arranged in the vertical rod; a sliding rod is arranged in the guide hole in a matched manner; a connecting rod is fixed at the upper ends of the two sliding rods; a guide mouth is arranged at the position, where the side wall opposite to the two guide holes are connected with the sliding rod along with the connecting rod, in a matched manner; the guide mouth extends to the lower end of the guide hole; mark heads are clamped at the lower ends of the vertical rods respectively through elastic clamps; the upper end of the mark head abuts against the lower end of the sliding rod; the upper periphery of the mark head and the elastic clamp are clamped in a matched manner; the lower partof the mark head is a sharp-pointed anchor head; and the sliding rod can be separated from the clamp position under the driving of the connecting rod, and anchored at a set calibration position. The elastically clamped device for labelling the monitoring area of the test field in the invention is smart in structural setting and convenient to use; the calibration operation efficiency can be increased; and furthermore, the labour intensity of operators also can be reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural tools, in particular to a device for calibrating a monitoring area in a test field. Background technique [0002] In the experimental farmland, when monitoring and managing seedlings, in order to ensure the consistency of the monitored seedlings, it is necessary to select seedlings in a fixed length and width area for observation and testing in a fixed area, so as to obtain accurate test seedlings in the experimental area. Various monitoring data during the plant growth cycle. The monitoring area calibrated in the prior art is generally an area with a fixed length and width. The area is calibrated by embedding marker heads exposed to the ground at the four corners of the area. During calibration, it is necessary to measure the dimensions of each side multiple times in order to accurately locate the position of the calibration point. , This method of measuring dimensions while calibrating, wh...

The monitoring area calibrated in the prior art is generally an area with a fixed length and width. The area is calibrated by embedding marker heads exposed to the ground at the four corners of the area. During calibration, it is necessary to measure the dimensions of each side multiple times in order to accurately locate the position of the calibration point. , this method of measuring dimensions while calibrating, the operator has to repeatedly lean over to measure and bury the marker head when performing multi-area calibration, which is very hard
