Soil loosening device for rhizoma polygonati planting

The invention discloses a soil loosening device for rhizoma polygonati planting, and relates to the field of planting of rhizoma polygonati. In accordance with the problems that in the prior art, a soil loosening device for planting of the rhizoma polygonati is low in efficiency, and the soil height is uneven after the soil is loosened, the invention provides the following scheme of the soil loosening device for rhizoma polygonati planting. The soil loosening device comprises a top plate, wherein side plates are fixedly connected to four corners of the bottom end of the top plate, an air cylinder is fixedly mounted at the middle of the bottom end of the top plate, a piston rod of the air cylinder faces downwards vertically, and a horizontal mounting plate is fixedly connected to the pistonrod; and the mounting plate is located between the side plates, two groups of vertical plates in symmetric distribution are fixedly connected to the bottom end of the mounting plate, a first loosening roller and a second loosening roller are respectively and rotatably mounted between each group of the vertical plates, and rotating shafts at one end of the first loosening roller and the second loosening roller both penetrate through the corresponding vertical plates. The soil loosening device not only can effectively improve the soil loosening efficiency, but also can perform flattening treatment on the loosened soil for different thickness, subsequent rhizoma polygonati planting is facilitated, and the soil loosening device is suitable for promotion.
