The invention relates to a convenient type straw treating device with a crushing function and based on internet of things. The convenient type straw treating device comprises a shell, a feeding pipe,an air outlet pipe and an electromagnetic valve, wherein the shell is internally provided with a pushing mechanism, a blocking mechanism, a crushing mechanism, a guide pipe, a storage chamber and a reaction chamber; the pushing mechanism comprises a first motor, a fixed rod, a cam, a disc, a gear, a rack, a sliding groove and a pushing plate. The convenient type straw treating device with the crushing function and based on internet of things has the beneficial effects that straws are pushed by the pushing mechanisms, and are crushed by the crushing mechanism simultaneously, so that the strawsare sectioned, further the contact area between the straws and bacteria is enlarged, the fermentation rate is increased and the practicability of the straw treating device is enhanced; an oxygen removing agent is sprayed by an oxygen removing mechanism, and then the content of oxygen in the reaction chamber 7 is maintained to be within 0.1%, so that a good living environment is provided for anaerobic bacteria, the fermentation process can be smoothly conducted, and further the convenience and the market competitiveness of the straw treating device are improved.
