It is made up of movable plate 4, support bar 6, hopper 5. The movable plate 4 is connected with the automatic crushing chamber 1 through the track welded on the inner wall of the automatic crushing chamber 1, and the hopper 5 is hinged with the automatic crushing chamber 1 and positioned with the automatic crushing chamber 1 through the support rod 6 and the screw 7, thus reducing the feeding port. It solves the technical problem of time-consuming and labor-intensive crushing of long straw. The fan of the straw automatic feeding pulverizer, the drive shaft of the fan is driven by the independent third drive shaft and wheel 18, the main shaft 13 drives the fan 20 to rotate by driving the second drive wheel 16, the V-belt 19 drives the third drive shaft and the wheel 18, The fan 20 is directly driven by the main shaft 13. First, it solves the disadvantage that the main shaft is easily damaged due to the violent vibration of the crushing chamber due to the damage of the fan. purpose of speed. The powder unloader of the straw automatic feeding pulverizer is provided with a recovery pipe 25 at the upper air outlet 24 of the powder unloader 21, and one end of the recovery pipe 25 is connected with the upper air outlet 24 of the powder unloader 21, and the other end is connected with the upper air outlet 24 of the crushing chamber 10. The upper cover 11 is connected, on the one hand, it solves the disadvantages of flying dust and material waste, on the other hand, it can increase the air volume in the crushing chamber and improve the crushing efficiency.

The positive effect of the utility model lies in that the concept is novel and ingenious, the structure is reasonable and practical, and the purpose of crushing straw feed is safe, efficient and energy-saving.
