Description

Automatic desert square grass planting machine

Technical Field

The invention relates to the technical field of desert control, in particular to an automatic desert square grass planter.

Background

Planting grass grids is one of the most effective means for controlling desert. Grass squares are typically laid out from straw or wheat straw. Through years of practice, the effect of blocking sandy soil is best when grass squares are paved into squares with the length of 1 meter, the width of 1 meter and the height of 10-20 centimeters. In this case, the height of the straw or wheat straw on the sand surface accounts for one third to one half of the total length of the straw or wheat straw, and the length of the straw or wheat straw under the sand surface is 13-15 cm. The grass squares are influenced by wind erosion within 4 to 5 years after being planted and need to be paved again. When the grass square lattice meets the air flow, a vortex is generated, and when the length and the width of the grass square lattice are 1 m respectively, the central part of the grass square lattice is only hollowed out by 10 cm in depth. The grass square is large, the hollowed depth of the central part is also deep, and the growth of sand-fixing plants in the grass square is not facilitated; if the square grass is small, the required grass and manpower are increased. Because the wind mainly carries gravel within 10 centimeters from the ground, the height of the grass square is more than 10 centimeters, generally 10-20 centimeters. The steps of laying grass squares manually are as follows: 1. drawing a square sideline on the sand; 2. putting the wheat straws on the side lines of the square, wherein the side lines are positioned in the middle of the wheat straws; 3. and a spade is used for forcibly and downwards treading along the square side line, so that the middle part of the wheat straw is stressed, and the two ends are naturally erected. The thickness of the stacked wheat straws cannot be too thick or too thin, and if the wheat straws are thick, the wheat straws can fall under the influence of self gravity; if the wheat straw is thin, the grass square can be blown away or blown down by wind, and the sand-resistant effect cannot be achieved.

The manual laying of the grass squares has large engineering quantity, a large number of hands and hard conditions, and is generally laid by farmers and herders around deserts. The manual laying is mostly concentrated on the crossing of spring and summer and the crossing of summer and autumn, the temperature is appropriate in the period, and the wind power is small. The time suitable for laying the grass squares all year around is about 4 months. The area of the grass square paved by people every day is 0.7-1 mu of land. With the development of society, people are more willing to go away from the countryside to other places which are more comfortable and suitable for self development to seek work, so the hands for controlling the desert are reduced. The desert control is a long-term process, the laying of the grass grids is only a flow of the desert control, and the following processes of planting the sand-fixing plants, maintaining the sand-fixing plants planted in the grass grids and the like are carried out. The reduction of hands of people for desert control means that many desertification control areas are careless, and the grassland covered on the desert can be degenerated for the second time and changed into the desert again. And a new desert can be generated each year under the influence of factors such as climate and human production activities.

A preferred use of the automatic desert square planter 10 of the present invention is as follows:

the caterpillar band drives the frame 20 to move forward, and when the transverse grass spreading device 30 passes through the sensing end of the transverse travel switch 901, the transverse travel switch 901 controls the fourth hydraulic solenoid valve 808 to enable the first hydraulic motor 305 to rotate reversely, so that the driving roller 306 drives the traction rope 307 to reversely pull the movable support 302. With the movement of the movable support 302, the second nail plates 303 are gradually covered with the forage, the movement speed of the transverse grass paving device 30 is the same as the running speed of the caterpillar track, when the transverse grass paving device 30 passes through the sensing end of the transverse movement travel switch 901 again, the travel distance travel switch 902 controls the first hydraulic solenoid valve 805 to enable the first hydraulic oil cylinder 304 to contract, the second nail plates 303 to open, and after the forage completely falls down, the first hydraulic oil cylinder 304 extends and the second nail plates 303 are closed. In the process, the transverse grass paving device 30 moves reversely to pave grass, and when the transverse grass paving device 30 passes through the sensing end of the chopping board travel switch 903, the chopping board travel switch 903 controls the vertical hydraulic oil cylinder 402 to extend, so that the chopping board 403 moves downwards to press the transversely paved grass in the sandy soil. The setting of the sensing end of the guillotine travel switch 903 is related to the speed of travel of the track to cause the guillotine 403 to depress from the middle of the fodder. Only when the transverse grass paving device 30 is detected by the sensing end of the chopping board travel switch 903 for the second time, the chopping board travel switch 903 controls the vertical hydraulic oil cylinder 402 to extend, and then the sensing times of the chopping board travel switch 903 return to zero. A common control is high and low level control. During the movement of the caterpillar tracks, the grass pressing wheels 602 press and fix the grass paved by the longitudinal grass paving device 50. Thus, the laid forage is pressed into a grid shape.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
