Description

Technical Field

[0001] The utility model belongs to the technical field of crushing equipment, and in particular relates to a livestock and poultry feed crusher. Background Art

[0002] Livestock and poultry often need to be fed with green fodder during breeding. Green fodder feeding requires the use of crushing equipment to crush the green fodder to achieve better feeding effects and facilitate the mixing of green fodder with other feeds.

[0003] The existing Chinese patent authorization announcement number CN209897691U discloses a green fodder crusher, including a shell, a bracket, a crushing device and a driving device. The upper outer wall of the shell is provided with a feed inlet, and the lower bottom wall is a screen outlet. A rotating shaft is provided in the shell, and the rotating shaft longitudinally penetrates the shell. The driving end of the rotating shaft passes through the top wall of the shell and is connected to the driving motor power. The other end of the rotating shaft is fixed to a support plate whose two ends are laterally fixed to the bottom side wall of the shell. The crushing device is composed of a rotating shaft fixed with an S-shaped blade. This scheme utilizes a spiral propulsion type rotating shaft while it has a crushing function. At the same time, the structure of the S-shaped blade is added. The blade is installed in a horizontal and inclined manner, so that the blade can sweep more space during the crushing process, reducing the gap between two adjacent sets of blades. The feed is crushed finer, which is beneficial to the digestion and absorption of livestock and poultry.
