Description

Technical Field

[0001] The utility model relates to the technical field of grass mixing, in particular to a grass mixing device used for cattle breeding. Background Art

[0002] Animal husbandry refers to the production process of using livestock, poultry and other animals that have been artificially raised and domesticated by humans, or the physiological functions of wild animals such as deer, musk deer, fox, mink, otter, quail, etc., through artificial breeding and reproduction, to transform plant energy such as forage and feed into animal energy, so as to obtain livestock products such as meat, eggs, milk, wool, cashmere, hides, silk and medicinal materials. Animal husbandry requires feeding cattle with forage, which can be dry or fresh. When raising cattle, for better digestion, the grass needs to be cut into small pieces and mixed with powdered feed before feeding.

[0003] The existing mixing device for cattle forage in the authorization announcement number CN217428931U relates to the field of animal husbandry. It includes a crushing box and four sets of brackets, the four sets of brackets are located below the crushing box and fixed, the upper surface of the crushing box is fixedly installed with a grass inlet, and the first crushing roller and the second crushing roller are rotatably installed inside the crushing box. The mixing device for cattle forage can drive the blade to cut the grass entering from the grass inlet into small segments through the relative rotation of the first crushing roller and the second crushing roller, and then cooperate with the second motor to drive the stirring shaft and the spiral blade to mix the grass and powder feed, which is convenient for carrying feed on the grass, which is beneficial to the consumption of cattle and can make cattle eat better. The second motor can drive the connecting rod and the scraper to rotate, so that the scraper can scrape off the grass and feed adsorbed on the inner wall of the mixing box, which is beneficial to mixing grass, and the second motor can be better protected by the protective cover.
