The invention provides a four-rod translation type special seed sowing device for plot breeding and belongs to agricultural machinery. A collection box provided with a seed guide pipe is hinged onto ashell body through front and rear connecting rods with the same length so as to form a parallelogram mechanism; a seed box is formed on the upper part of the shell body through side plates; a hairbrush is fixedly arranged at the lower part of the seed box and is located on the shell body; the middle part of the shell body is rotatably assembled and is sequentially provided with driving shafts ofa round shaft section and a hexagonal shaft section from outside to inside through a bearing; the bearing is fixed by an end cover; a seed sowing disc, which is uniformly provided with indented holesin the peripheral direction, sleeves the hexagonal shaft section through a hexagonal hole; a handle provided with a large shaft hole is fixedly arranged in the middle of the seed sowing disc; a convexshaft is arranged at two ends of a sleeve ring which rotatably sleeves the handle; the convex shaft is inserted into U-shaped holes formed in the middle of the front connecting rods. According to thefour-rod translation type special seed sowing device for the plot breeding, seeds in the seed box and the indented holes of the seed sowing disc are rapidly filled into the collection box hoisted through the connecting rods in a manner of moving and rotating the seed sowing disc with the handle, and then the seed sowing disc is returned back to exchange the seeds, so as to finish the seed sowingwork of the next plot. Meanwhile, the seed sowing device is novel in design and simple to operate and is used for preventing interbreeding.
