Description

Plowing device along beach

Technical field

The invention relates to a tilling device, in particular to a tilling device along the beach.

Background technique

Tidal flats, due to the action of tides, are sometimes submerged by water and sometimes exposed to the surface. The upper part is often exposed to the water and the lower part is often submerged by water. Due to the diverse types of banks, the effects of currents, and the sand content of rivers and other factors, some banks are scoured by water and the tidal flats recede toward the land; some banks have strong accumulation and the tidal flats stretch toward the direction of water; The shore is relatively stable, and the range of tidal flats is relatively stable. With the continuous application of tidal flat areas, plowing operations need to be carried out during the planting process in tidal flat areas to facilitate the permeability of the lower soil and remove the roots of weeds. However, because the soil in some places in the tidal flat area is relatively soft, the tilling device of the prior art, especially the way of only setting auxiliary support, because the supporting device is generally fixed, this leads to either the advancement of the tillage Large resistance is generated, or it is easy to sink and it is difficult to assist forward, and it is easy to sink into the soil when plowing the tidal flat, which is inconvenient for plowing. Moreover, this leads to the inability to accurately grasp the depth of plowing, it is easy to turn more or less, and it is difficult to adapt to the application of tidal flats.

Therefore, the present invention provides a tilling device along the beach to solve the problems raised in the background art.
