Rolling wheel type fertilization and scarification device

The utility model discloses a rolling wheel type fertilization and scarification device which comprises a rack and a scarifying wheel. The scarifying wheel is rotatably connected to the rack, and tooth tips are formed on the scarifying wheel; the rolling wheel type fertilization and scarification device further comprises a material case and a feeding wheel, the material case comprises a base plate and side plates which are arranged on the periphery of the base plate, through grooves are formed in the side plate, near the scarifying wheel, of the material case, the feeding wheel is rotatably connected in the through grooves, the axial direction of the feeding wheel is parallel to the axial direction of the scarifying wheel, and tooth blocks which can abut against the tooth tips of the scarifying wheel are formed on the feeding wheel, wherein material containing grooves which concave inwards are formed between two tooth blocks of the feeding wheel. By means of the rolling wheel type fertilization and scarification device, when scarification is conducted, the scarifying wheel rotates, and the tooth tips are formed on the scarifying wheel, so that soil blocks in soil can be broken evenly, materials can be driven to come out of the material case through the rotation of the scarifying wheel, the fertilization and the scarification can be conducted on the soil, the time is saved, and the efficiency is improved. If the scarifying wheel stops rotating, the feeding wheel can not rotate, and the materials can not be driven, so that the evenness of the fertilization is guaranteed, and too much fertilization at one place is prevented.
