The upward movement of the connecting rod 4 will drive the lower connecting rod 7 to rotate counterclockwise. Due to the large frame mounting seat 1, the upper connecting rod 6, There is a parallelogram structure between the lower connecting rod 7 and the square tube 8. The counterclockwise rotation of the lower connecting rod 7 will drive the square tube 8 to move vertically downward, so that the seeding plate 10 linked with the square tube 8 will keep contact with the ground downward; the large frame mounting seat 1, the upper connecting rod 6, the lower connecting rod 7 and the square tube 8 can form a parallelogram four-rod suspension structure, so that when the large frame mounting seat 1 is vertically installed on the large frame through the large frame fixing hoop 9, the square tube 8 can only move vertically up and down, so that when the square tube 8 is affected by the terrain and floats, the seeding plate 10 connected to the square tube 8 can When the seeding disc 10 is displaced up and down to a large extent, and the soft seed guide tube 12 installed on the square tube 8 through the positioning piece 11 can be displaced accordingly, so that the lower end of the soft seed guide tube 12 always maintains the same distance and angle with the sowing ground, thereby improving the stability of suspended sowing. When it is necessary to adjust the elastic force according to the hardness of the terrain, the spring 5 with different elastic forces can be replaced by removing the pull rod part 3 to change it. The operation is as follows: the hoop 34 is slid upward to make it disengage from a group of clamping hands 33, so that a group of clamping hands 33 can be rotated to both sides to open, so that a group of clamping hands 33 is disconnected from the connecting rod 4. At this time, the rod body 31 can be removed and replaced with a spring 5 with appropriate elastic force, and the pull rod part 3 can be reset according to the above disassembly steps, so that the sowing disc 10 of the parallel floating sowing disc can be displaced up and down to a large extent according to the increase of ground floating, and the elastic force of the spring 5 can be adjusted according to the terrain with different hardness, so that it can better adapt to the terrain, and the distance and angle between the soft seed guide tube 12 and the ground are not changed, thereby improving the stability of suspended sowing.
