After the quarrel, the upper and Xia dissociation tube bodies (5) of lime (13) are inserted and combined with the pressure record (7).The other side will form the ridge after the lailin (16-year-old) award.After the hydraulic pressure cylinder (7) (14)) and the hinge (15)) are introduced into the sea pine conduit (5), the guide area (20) and the shaft (17) of the ridge are combined on the back side, and the spring (19) of the rear section of the ridge (18) is formed by combining with the ship group This is formed for ploughing and drainage to form operation and ridge.
