Forage cutting machine with discharging and staged recovery

[0024] like figure 1 , figure 2 As shown, the forage cutting machine with unloading and graded recovery includes a support 5 with a door-type structure as a whole. In the support 5, there are moving knives and static knives that cut and cooperate with each other in sequence from top to bottom. The moving knives include knife seats 3. A number of cutter heads 4 are installed at the bottom of the knife seat 3. The top of the knife seat 3 is connected with a power mechanism 13 for the up and down movement of the knife seat 3. The power mechanism 13 is fixed on the top of the bracket 5. The static knife includes a static knife plate 9. The static knife plate 9 is provided with a knife hole 8 that communicates up and down and is cut and matched with the cutter head 4. The static knife plate 9 is arranged on the support 5, and a slide plate that slides left and right along the upper surface of the static knife plate 9 is arranged on the top of the static knife plate 9. 12. The front

[0028] A further change is made on the basis of the first embodiment, the power mechanism 13 is changed into an air cylinder, the cylinder body of which is fixed on the bracket 5 , and the piston rod is connected to the tool seat 3 . Others are the same as embodiment one.

[0030] Further changes are made on the basis of Embodiment 1, and the power mechanism 13 is changed. The power mechanism 13 includes a screw and a nut that cooperate with each other. Only free rotation can be done on the support 5, and the nut is driven by a gear set. Others are the same as embodiment one.
