AI Technical Summary
When crushing straws, existing crushing equipment fails to effectively filter dust in the air, and fails to collect and crush the incompletely crushed straws again, resulting in poor crushing effect.
A straw crushing equipment for returning vegetable straw to the field was designed, and multiple crushing knives were used to crush it, and dust was collected through an absorption mechanism. The equipment is equipped with a first filter and a second filter. The crushed straw and the unmilled straw are separated by the vibration mechanism driven by the rotating wheel, and the fan blades are driven by a small motor to filter and discharge gas.
Through the design of multiple crushing knives, the crushing effect of straw is significantly improved; the use of the absorption mechanism effectively collects dust and reduces dust emissions; the use of vibration mechanism can effectively separate the crushed straw from the unfinished part, improving the overall efficiency of the crushing equipment.
