Claim 0:
1. A two-way soil clearing device, configured to be used with a single-ridge grapevine, the two-way soil clearing device comprising:
a frame part;
a soil clearing mechanism,
a distance measuring sensor,
an expansion and contraction device; and
a control unit;
wherein the frame part comprises a left side frame and a right side frame that are laterally connectable by a connecting device that is removeable from the frame part, such that the left side frame and the right side frame are attachable in a longitudinal direction;
wherein the soil clearing mechanism is arranged on the left side frame and the right side frame and comprises,
a chute plate that has a top side and bottom side;
a scraper connected to the bottom side of the chute plate;
a reset mechanism mounted on the top side of the chute plate that resets the scraper, position, wherein the reset mechanism comprises,

a torsional spring, at least one base plate, at least one lifting lug, and a cylindrical pin arranged therebetween, wherein the base plate and the lifting lug connect to the top side of the chute plate to the frame part and the torsional spring is sleeved over the cylindrical pin between the at least one lifting lug and the at least one base plate;
wherein the distance measuring sensor is arranged on a respective left side frame and right side frame in a location in front of the soil clearing mechanism arranged on the same respective left side frame and right side frame;
wherein the expansion and contraction device is attached to the frame part behind the soil clearing mechanism, the expansion and contraction device comprising,
a fixed mounting plate arranged on the scrapper,
a telescopic electric cylinder comprising one end that is attached to the frame part and another end that is operably connected to the fixed mounting plate on the scraper;

wherein the control unit is connected to the distance measuring sensor and the expansion and contraction device, such that control device is configured to receive from the distance measuring sensor a distance between the scraper and the soil and adjusts the telescopic electric cylinder accordingly to rotate the scraper on the cylindrical pin to adjust a depth of the scraper in the soil and when the scraper is subjected to a resistance, the scraper swings away from the resistance on the cylindrical pin, which compresses the torsional spring until the resistance is passed and the torsional spring resets the position of the scraper.
