Technical Field

The utility model relates to the technical field of ecological protection wind-proof sand-fixation machinery, in particular to a grass square grid laying and planting vehicle for wind-proof sand fixation.

Background

The grass square sand barrier is a sand control method for preventing wind, fixing sand and conserving water, materials such as wheat straw, rice straw, reed and the like are used for binding the grass square sand barrier in a desert to form square wind-blocking walls on a flowing sand dune, the grass square sand barrier can enable the ground to be rough and weaken erosion of wind power on one hand, and can also retain water on the other hand, improve the water content of a sand layer, and facilitate survival of sand-fixing plants, so that the binding of the grass square sand barrier has extremely important significance for preventing wind and fixing sand.

When the grass square grid is tied, firstly, a construction square grid line is marked on the sand hill, so that the sand barrier is perpendicular to the local main wind direction. And then the materials such as wheat straw or rice straw which are uniformly and orderly trimmed are horizontally placed on the grid lines, a tool such as a plate spade is placed in the middle of grass laying, the grass is forcibly inserted into the sand layer, the two ends of the grass are lifted up, the grass is vertically arranged on the sand surface, the height of the grass exposed out of the ground is about 20 cm-25 cm, then the sand is buried on the root base of the grass grid sand barrier by the tool, the grass grid sand barrier is firm, and according to experiments, the grass grid sand barrier has the best windproof and sand-fixing effects when the shape of the single grass grid sand barrier is a square of 1 meter multiplied by 1 meter.

However, the current planting mode needs to manually spread forage first and then manually press or mechanically press the forage, so that the two ends of the straw are tilted, and the middle part of the straw is pressed into sandy soil, thereby playing the role of protecting the sandy soil. In the Chinese patent No. 213805305U, a simple and efficient grass square lattice planting machine is disclosed, and grass paving assemblies are driven by tractors to release manpower, but the tractors are large in size and cannot work in narrower places, the flexibility is low, grass square lattice paving can be completed only by adjusting the direction of a vehicle body during paving, a series of operations are also required to be carried out by manually driving the machine during operation, the automation is insufficient and soil facing different regions cannot be controlled, and the pressing depth of the straws is not controlled. In the Chinese patent application CN202210156348.4, a grass square grid laying auxiliary desertification control vehicle is disclosed, wherein the grass square grid laying auxiliary desertification control vehicle can only lay one square grid line in one direction at a time, the transverse and longitudinal laying needs to be turned, the working efficiency is low, the grass storage quantity is small, the straw needs to be supplemented when a small path is laid, and the manpower cannot be completely liberated.

It is therefore highly desirable to design a small grass square lattice laying vehicle that can be mechanically released from manpower to efficiently perform the laying of a dry and complex grass square lattice.
