Land marker and application method thereof

Abstract

The invention discloses a land marker, comprising a bucket. The lower end of the bucket is provided with a powder outlet; the outer wall of the bucket is connected with two traction members; the otherends of the traction members are fixedly connected with a first drum and a second drum; the first drum and the second drum are connected to two support rods respectively; each support rod is providedwith a first through hole; the traction members are passed through the first through holes and wound to the first drum and the second drum respectively; the bucket is also slidably connected with a fastener; the two ends of the fastener are connected with the support rods respectively. The land marker is simple in structure; the bucket can be reciprocated directly through the first drum and the second drum, so that round trips of workers between the two ends of a land are not required; a ball lifting mechanism allows the powder outlet to be opened and closed; a spherical arc face allows limestone powder to slide down along the arc face, forming uniform continuous lines; a protrusion helps effectively prevent the powder outlet from being blocked by the limestone powder; the land marker isconvenient to operate and simple and practical.

Description

technical field [0001] The invention relates to the technical field of marking devices, in particular to a field marking device and a method for using the same. Background technique [0002] In agricultural science experiments, in order to ensure the accuracy of the experimental data and make the sowing row and plant spacing as consistent as possible, it is necessary to mark the sowing position in the experimental field before sowing. At present, the method of marking is at first to mark the row marks in the longitudinal direction according to the needs of the sowing row spacing. Since the distance in the longitudinal direction is longer, a mechanically driven row marker can be used to operate. When rowing horizontally, the following methods are mainly used: First, the method of pulling the horizontal line is adopted. Two operators stretch the thin rope, and one person in the middle steps on it or presses it with a wheelbarrow along the thin rope. Bending, resulting in erro...

Problems solved by technology

[0006] The above-mentioned device uses the staff to pull the pull rod to drive the marking knife to mark the line, but the labor intensity is high, and it is inconvenient to operate in the field, and the line drawn by the marking knife is not obvious enough, and it is easy to bend, which is not as clear as lime powder.
