Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural machinery, and in particular to a furrow marker capable of freely changing plant row spacing based on wheel synchronization. BACKGROUND

[0002] The furrow marker is one of the important components of the seeding machine. During the operation of the seeding machine, the furrow marker draws a series of recognizable deep marks on the ground, thereby dividing the land into a plurality of equidistant small blocks, so as to control the growth direction and spacing of crops.

[0003] In the experimental study of agricultural science, the furrow marker plays an irreplaceable role in controlling crop population relationship, crop growth and development state, and accuracy of experimental data. By controlling the row spacing through the furrow marker, the planting density of crops can be effectively controlled. If the planting density of the same crop population is too high, population inhibition will occur, otherwise light and temperature resources will be wasted; both of which will affect the final crop growth and development state and the accuracy of experimental data. So far, the application of the furrow marker in agricultural science experiments has formed a scale, but the structures and functions of different furrow markers are different.

[0004] In recent years, with the explosive development of professional scientific experiments, the demand for furrow markers in agricultural science experiments is increasing, and the requirements are becoming higher and higher. With the improvement of technical requirements, the development of furrow markers has also made good progress. For example, the Chinese invention patent with the publication number CN114793574A and the invention name Portable Furrow Marker for Crop Field Experiment; and the Chinese utility model patent with the publication number CN219228379U and the invention name Crop Furrow Marker, disclose two kinds of furrow markers for agricultural science experiments. The former can effectively improve the collimation of the furrow marker through structural design; and the latter can adjust the row spacing and control the furrow depth through structural design.

[0005] However, the existing agricultural science experiment furrow markers do not have the function of freely changing plant row spacing, so the accuracy of the agricultural science experiment data cannot be further improved. CONTENT OF THE UTILITY MODEL
