Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

As shown in fig. 1 to 3, the utility model provides a forage grass comminution device, including carrying section of thick bamboo 1, rotary drum 2 and a plurality of cutter knife 3, be provided with screw feed oar 4 within carrying section of thick bamboo 1, the one end of carrying section of thick bamboo 1 is as the feed inlet, and the other end of carrying section of thick bamboo 1 is as the discharge gate, and discharge gate department is by having connect rotary drum 2 coaxially, and the cover is equipped with cutter ring 5 within rotary drum 2, and cutter knife 3's one end fixed mounting is on cutter ring 5, and cutter knife 3's the other end aims at the central axis of cutter ring 5.

By adopting the technical proposal of the utility model, under the rotation of the screw conveying propeller in the conveying cylinder, the forage grass is conveyed to the discharge port from the feed inlet of the conveying cylinder, at the discharge port, the whole rotary drum rotates relative to the conveying cylinder and drives the cutter ring and the chopping cutter to rotate, thereby chopping the forage grass, compared with the prior art, the utility model connects the conveying device and the chopping device of the forage grass into a whole, simplifies the structure of the device, reduces the difficulty of manufacturing and maintaining the device, and the forage grass is conveyed around the circumferential peripheral area of the screw conveying propeller shaft all the time along with the rotation of the screw conveying propeller, and the chopping cutter is also arranged at the circumferential peripheral area of the screw conveying propeller shaft for chopping operation at the same time, thereby avoiding the spatial position of the screw conveying propeller shaft, when the forage grass amount is increased, the length of the chopping cutter can be increased, and the chopping cutter can be always positioned at the circumferential peripheral area of the screw conveying propeller shaft, so that the forage grass can be fully and completely cut.
