Description

Technical Field

[0001] The utility model relates to the technical field of beef cattle breeding, in particular to a novel grass cutting device. Background Art

[0002] Beef cattle are cattle used for meat, which are mainly used to produce beef. They are characterized by plump body, fast weight gain, high feed utilization rate, good meat production performance, and good meat taste. Beef cattle not only provide people with meat products, but also provide people with other side dishes. In beef cattle breeding, feed needs to be prepared for them. Usually, the grass is cut by a grass cutting device, and then the feed is prepared for the beef cattle so as to feed them.

[0003] For example, a Chinese utility model patent (CN217770910U) discloses a forage cutting table for beef cattle breeding with adjustable forage length, which records: "It includes a cutting table body, a first connecting plate and a first movable groove, the outer side of the cutting table body is connected to the first connecting plate, the first connecting plate is provided with a first movable groove, the first connecting plate is provided with a second connecting plate, and the outer side of the rotating shaft is connected to a cutting knife", and it is proposed that: "The existing forage cutting tables for beef cattle breeding have the following deficiencies in use, such as the inability to control the cutting length of the forage, the existing cutting knives are generally fixed on the cutting table, and when cutting the forage, the cutting length is manually controlled; the forage cannot be pressed, and the existing forage cutting tables for beef cattle breeding are prone to breakage and flying due to the cutting pressure when cutting the forage." Technical deficiencies.
