Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry, in particular to a forage crushing device. Background Art

[0002] After harvesting, forage grass needs to be processed before it can be fed to livestock, because livestock have a low digestion and utilization rate for stalks and segments of forage grass, and their nutrient absorption is limited, so they cannot fully absorb the nutrients from the forage grass. Using a forage grinder to break up the forage grass and mix it with other feed can provide livestock with comprehensive nutrition.

[0003] For example, the patent document with the announcement number CN219981598U discloses a forage crushing device, which has multiple plug rods fixed on opposite sides of two fixed plates. When the electric push rod is started, the two fixed plates are moved closer to each other by the limiting effect of the limit frame on the clamping rod. The two groups of plug rods are used to move the forage forward, and the pulling of the two feeding rods makes the feeding rate stable, which is convenient for controlling the rate of forage entry. However, the device uses a fixed blade, which makes it difficult to adjust the size of the crushed forage. Utility Model Content
