Problems solved by technology

[0003] For the detection of ditching depth in China, most of the methods are to change the shape and structure of the working tools, resulting in poor versatility of the detection device, or to use the ranging sensor to detect the distance from a certain plane to the ground surface. Due to the complex surface conditions, especially on no-tillage ground, this kind of detection The measurement error is large

Abstract

The invention discloses a universal ditching depth detection device, which comprises a machine tool hanging frame, a ground profiling device, a longitudinal displacement measurement device and a transverse displacement balancing device. The transverse displacement balancing device and the ground profiling device are mounted on the machine tool hanging frame, and the ground profiling device is hinged to the machine tool hanging frame; the transverse displacement balancing device is arranged at the upper part of the profiling device; and the upper end of the longitudinal displacement measuring device is connected with the transverse displacement balancing device, and the lower end is hinged to the ground profiling device.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a general-purpose ditching depth detection device. Background technique [0002] The consistency of trenching depth is an important indicator of precision seeding, and it is the premise of controlling the consistency and stability of seeding and fertilization depth. During the field work of the opener, due to the spatial variability of the soil and the large amount of surface undulation under the condition of conservation tillage, the depth of the trench is inconsistent, which affects the accuracy of subsequent operations and crop growth. When the machine is moving forward, the real-time detection of the ditch depth can provide data reference for the subsequent control system to adjust the ditch depth. [0003] For the detection of ditching depth in China, most of the methods are to change the shape and structure of the working tools, resulting in poor versatility of the de...
