Description

Grass curtain laying device for desert sand stabilization

Technical Field

The utility model relates to a grass curtain laying device, concretely relates to a grass curtain laying device for desert sand stabilization.

Background

Desert is mainly a deserted area where the ground is completely covered by sand, plants are very rare, rainwater is rare and air is dry. Desert is also used as "sand curtain" as a region with drought and scarce plants. In order to prevent the desert from expanding, the sand needs to be fixed to the desert to prevent the sand gravel from drifting out of the desert along with the monsoon. The current desert sand fixation method is as follows: the grass poles are artificially inserted in the desert in a cuttage mode, fences are formed through the grass poles, and therefore wind power between the grass poles is reduced, and drifting of gravel between the grass poles is further reduced. It has the following drawbacks: because the cuttage is carried out manually, a large amount of labor is manual operation, so that the labor intensity is high, and the working efficiency is low; meanwhile, due to the difference of individual degrees, the cuttage depths are inconsistent, and when the cuttage is shallow, the grass stems are easily blown away, so that the sand fixation effect is easily lost.

Although it can wholly improve and plant grass efficiency, reduces operating personnel's working strength. But because the fixed frame of planting grass that sets up directly over two sets of grass knife tackle of grass case, because there is a difference in height in grass pole and the ground of grass incasement, the grass pole is crooked easily when falling to the ditch inslot of planting grass knife tackle excavation, and then leads to the firm husky effect of grass pole poor easily. On the other hand, the method can also plant grass by planting grass seeds or tree seeds, but the survival rate of the grass seeds is low due to water shortage in the desert, and then the sand fixing effect is still poor. Therefore, it is necessary to design a grass curtain laying device to solve the problem of poor sand fixation effect.
