Abstract

The invention relates to a sand control mechanical device which can roll grass squares in desert and sand environment for controlling sand dune flow caused by wind sand. Four grass placing boxes are arranged in the device and are divided into a front part and a rear part according to the structure. Laying and fixing longitudinal forage on the front half part: the forage falls to the conveyor belt, is controlled by the conveyor belt, uniformly falls to the sharp-tooth chain, is uniformly paved on the sand along with the chain, is pressed down by the pressing wheel, and is further fastened by the roller; laying and fixing transverse forage in the rear half part: like the previous part, the forage is spread flatly, and the pressing plate exerts pressure to vertically fix the forage on the sand and vertically draw out the forage to do intermittent motion. The device adopts a PLC to control a stepping motor, and utilizes the characteristics and the layout of different grass laying directions, the cyclic intermittent motion of the sliding block and the separation work of the front part and the rear part. Not only can be laid with the grass square grids shaped like Chinese character 'tian' once, but also the working time is reduced, so as to obtain the maximum efficiency. The device is firmer, and the service life is prolonged.

Description

Wind-proof sand-fixing grass grid laying machine

Technical Field

The invention belongs to the technical field of ecological restoration, and particularly relates to a mechanical device for desertification control, which can roll out bidirectional grass grids for desertification control.

Background

Desertification is a major global environmental problem facing mankind at present, and troubles the survival and development of human society. The soil erosion caused by the movement of wind and sand is one of the main manifestations of sandy desertification. The harm caused by the desert is also due to the actions of wind erosion, transportation and accumulation of the wind and sand flow. In order to prevent the sand dune from moving, firstly, loose sand grains on the surface of the sand dune should be controlled not to be blown by wind, weeds, branches and other materials can be utilized, and grass is inserted into the sand dune to arrange a windbreak or cover the sand surface. The most effective and feasible method for fixing quicksand at present is to roll grass squares, the rolled grass squares are mainly manual at present, the environment is severe due to wind and sunlight, the labor intensity is high, the cost is high, the efficiency is low, the service life is low due to different depths of the artificially rolled grass squares, and therefore the problem needs to be solved automatically, labor force is liberated, the efficiency of rolling the grass squares is improved, and the requirement of desert control is met. The desert terrain is complex, the texture is soft, the mechanical walking is difficult, and proper wheels and power are needed, so that the grass square sand barrier is difficult to roll. A grass grid sand barrier is a sand control method for preventing wind, fixing sand and conserving water, and is made up of wheat straw, rice straw and reed through binding in desert to form a grid. The grass grid sand barrier can roughen the ground, reduce wind power, intercept moisture such as rainwater, improve the water content of a sand layer and facilitate the survival of sand-fixing plants. After the grass grid sand barriers are laid, drought-resistant grass trees such as artemisia desertorum, husked rice, flower sticks, Calligonum mongolicum and the like can be sown, and after the hay is weathered, nutrients can be provided for seeds or vegetation, so that the sand has a layer of crust which can contain moisture and oxygen, and the ecological restoration effect is achieved. The existing grass grid laying machine can only lay longitudinal hay, cannot directly become grass grids, needs to change directions, is time-consuming, labor-consuming and expensive, and can break the originally laid hay in the running process when the device lays the transverse hay, so that the grass grid sand barrier is unstable, the wind prevention and sand fixation effects are not strong, and the effect of recovering a desert ecosystem cannot be achieved.
