[0007] The hammers are fixed on the hammer cutter head, and the hammers are fixed on the hammer cutter head.

[0008] Through the above arrangement, the whole grass dry block enters the crushing chamber from the feeding hopper, the crushing roller cuts and crushes the whole grass dry block into small grass, the small grass enters the crushing chamber, the hammers on the crushing roller beat the small grass, and the hammers beat the small grass into grass powder. The grass powder falls to the discharge port through the screen. After cutting and hammering the whole grass block, the cut grass block is easier to be beaten, and the efficiency is higher than that of only cutting and hammering. At the same time, the cut grass block has smaller size and is less likely to be stuck during hammering in the crushing chamber.

[0009] The crushing chamber is provided with an air chamber on one side, the air chamber is communicated with the discharge port, a fan is arranged in the air chamber, and the fan is coaxially connected with the crushing roller. The fan is used for blowing the grass powder to the discharge port.
