Small traction soil disinfection machine

The invention discloses a small traction soil disinfection machine. The machine comprises a frame, a power transmission system, a rotary tilling system and a steam system, a three-point suspension frame is installed at the front end of the frame for connecting a tractor, a power rotates a hollow cutter shaft through a change gear box and chain drive, and as the soil is tilled rotatably, the high-temperature steam enters a pipe joint through a hose and enters the hollow cutter shaft, and finally passes into a steam branch pipe and is sprayed through an exhaust hole on the steam branch pipe. Themachine has the advantages of simple structure, convenient operation and continuous steam sterilization, is suitable for deep soil of narrow blocks such as greenhouses and the like, reduces the laborintensity and improves the efficiency of soil disinfection. 本发明公开了种小型牵引式土壤消毒机，包括机架，动力传输系统，旋耕系统，蒸汽系统，其特征在于：三点悬挂架安装在机架的前端，用于连接拖拉机，动力通过变速齿轮箱和链传动使空心刀轴转动，在旋耕土壤的同时，高温蒸汽通过软管接入管接头从而进入空心刀轴中，最终通入蒸汽支管并经由蒸汽支管上的排气孔喷出，本发明的优点是：结构简单、操作便捷，能够连
