Description

Full-automatic grass square grid laying machine and full-automatic grass square grid laying method

Technical Field

The invention belongs to the technical field of desertification control engineering, and particularly relates to a full-automatic grass square grid laying machine and a full-automatic grass square grid laying method.

Background

Desertification is caused by the fact that the ecological system is destroyed due to excessive pursuit of economic activities by human beings, so that an environment change process similar to desert landscape appears in non-desert areas. Land desertification is a sign of environmental degradation and is a positive feedback process of environmental instability. If no fundamental measures are taken, the process of the wind erosion and desertification of the land can not be automatically stopped, but the development can be accelerated.

At present, one of the national means for controlling land desertification is to arrange sand barriers, including grass grid sand barriers, clay sand barriers and the like. The Chinese herbal check sand barrier is made of wheat straw, rice straw, reed and other materials, and is tied on a flowing sand dune to form a wind-shield wall so as to weaken the erosion of wind power, and meanwhile, the Chinese herbal check sand barrier has the function of intercepting rainfall, can improve the water content of a sand layer and is beneficial to the growth of sand plants.

The prior common use of China is still the traditional grass square grid laying technology, and the main steps of grass square grid production are wheat straw sorting, wheat straw placing and treading and forming. The worker wears the glove and picks up a proper amount of wheat straw to flap against the wind, and then flares the broken wheat straw and the shorter wheat straw to leave the long wheat straw which is suitable to be used as a grass square. After the wheat straw is sorted, the worker places the wheat straw along the square, which has been drawn, and keeps the thickness of the wheat straw constant while the wheat straw is placed. And finally, the placed wheat straws are pressed downwards by using a shovel along the direction of the square grid with force, and two sides of the wheat straws naturally stand up due to the force of the shovel, so that a natural barrier consisting of the wheat straws is formed. After the wheat straw is erected, workers can step the surrounding soil on the root of the wheat straw, so that the stability of the wheat straw barrier is enhanced. The grass square sand barrier needs to consume a large amount of manpower and material resources, takes a lot of labor in the laying process, needs manual maintenance, and needs manual screening of wheat straw and production when grass squares are produced.

Ningxia now uses brush-shaped net rope type grass grid sand barrier sand control technology. Workers need to use a special grass square sand barrier material production device to fix the grass ropes and the brush-shaped grass curtains together in advance, so that a certain number of brush-shaped net ropes are obtained. After the production is finished, workers need to transport the products to the areas needing to be treated by trucks. In the process of making the grass square, workers need to lay the brush-shaped net rope on the sand ground in a mode of 1m multiplied by 1m by one group. Only 3 minutes are needed, and a net rope type grass square grid sand barrier with the area of 8m2 can be manufactured. Compared with the traditional manufacturing mode of the grass square sand barrier, the net rope type grass square sand barrier only fixes the periphery, and the net rope intersection is tied and fixed by using the rope. Although the method improves the manufacturing efficiency and reduces the cost to a certain extent, certain manpower is still required.

For semi-automatization machinery, the cost of labor is reduced to the very big degree of robot is laid to the grass curtain, and mechanical structure can also guarantee the sand prevention effect of grass square sand barrier, reduces follow-up maintenance process. The straw mat laying robot mainly comprises a tractor, a longitudinal laying mechanism and a transverse laying mechanism, the desert vehicle is used for traction, and the longitudinal laying mechanism and the transverse laying mechanism execute a task of laying straw squares. The robot can realize automatic production and manufacture of the grass square sand barrier, but needs to stop repeatedly in the laying process, improves the efficiency and saves labor compared with the traditional method, but the result is still unsatisfactory, a better solution is provided, and higher efficiency is considered while the labor is saved.

The cylindrical finished straw mat 70 is installed on a straw mat laying machine, the straw mat laying machine is pulled by a tractor to move along a preset direction, the straw mat laying machine unfolds the finished straw mat 70 in the advancing process, and cuts off the straw mat and rolls the cut straw mat into sandy soil when the length of the straw mat reaches the preset length, wherein the rolling direction of the straw mat is perpendicular to the pulling direction of the tractor.

To sum up, the fully automatic grass grid laying machine 100 utilizes a smart mechanical structure to achieve the target functions: wheat straw is sorted, straw curtains are manufactured, and straw squares are laid continuously. If the grass square is put into use, the cost can be reduced, the labor is saved, the laying efficiency is improved, and meanwhile the laying quality of the grass square can be guaranteed.

Compared with the existing grass grid laying technology, the full-automatic grass grid laying machine 100 only needs three workers, namely one worker drives the tractor 50, one worker puts standby forage into the forage screening machine 10, one worker replaces the straw mat, and the rest steps are finished by the machine, so that the number of workers can be reduced, and the working strength can be reduced. The mat laying machine 40 can control the depth of insertion of the wheat straw so that the wheat straw does not collapse due to insufficient insertion depth, thereby increasing maintenance costs. The step of making the mat may be performed at the place of laying or at the tractor 50 or at the place where the wheat straw grows, and the determination of the place of making may be made by integrating such factors as the distance between the place of laying and the place where the wheat straw grows and the cost of transportation, so as to select the most convenient and economical form. The flexibility of the device can enable workers to select the device independently, and the convenience is enhanced.

Firstly, a straw mat laying robot needs two slotting tools in the transverse direction and the longitudinal direction, and belongs to intermittent laying; the full-automatic grass grid laying machine 100 can realize the production of grass grid sand barriers in the transverse direction and the longitudinal direction only by using one rolling mechanism 45, belongs to continuous laying and can improve the laying efficiency. In addition, the transverse slotting tools and the longitudinal slotting tools of the straw mat laying robot need to be frequently lifted and put down, and in order not to influence the laying of the grass square sand barriers, the lifting time and the putting down time of the slotting tools are as short as possible. However, the increased speed brings certain impact force to the machine itself, which is not beneficial for long-term use. The full-automatic grass grid laying machine 100 of the present invention switches two rollers in a rotating manner, so that there is substantially no impact on the tractor 50, and the service life of the machine is prolonged.

Secondly, the straw mat laying robot needs to stop once every 1 meter in the working process, the error is increased due to frequent starting and stopping, and meanwhile, a driver can sway back and forth due to inertia to cause discomfort, so that the straw mat laying robot is not beneficial to work. The full-automatic grass square groove paving machine does not need to stop in the working process, so that the discomfort of a driver can be reduced, and the grass paving efficiency is improved.
