The invention discloses a pneumatic cleaning-type feed screening device which comprises a feeding hopper, a screening barrel, a barrel cover and a screening mesh, wherein the screening barrel is mounted on a rack; the screening barrel and the rack are connected through a plurality of damping springs; the barrel cover is mounted at a top opening of the screening barrel; the bottom of the feeding hopper is connected with a material setting pipe through a connecting pipe; the bottom of the material setting pipe is connected with the barrel cover; a uniform-distribution material setting device ismounted in the material setting pipe; the horizontal screening mesh is mounted in the screening barrel; a vibrating motor is mounted at the bottom of the screening mesh; and a conical pipe is connected with the bottom of the screening barrel. The pneumatic cleaning-type feed screening device disclosed by the invention has the following beneficial effects: when excessive impurities are retained onthe surface of the screening mesh, high-pressure air can be injected into a high-pressure air pipe, so that the impurities are blown away by high-pressure airflow, discharged through an impurity removing pipe, and cleared in time; the normal progress of the screening operation can be guaranteed; and meanwhile, feed can uniformly and equivalently drop into the screening barrel through the uniform-distribution dialing device, so that the workload uniformity of the screening mesh can be guaranteed.
Description
technical field [0001] The invention relates to the technical field of feed processing, in particular to a pneumatic cleaning type feed screening device. Background technique [0002] Feed is the main food for raising animals in modern animal husbandry. Feed is usually composed of concentrate and roughage, wherein the particle size of concentrate and roughage is different, and the ratio of quantitative distribution in the feed is also different. Raised animals need different ratios of concentrated feed and roughage for feeding at different stages of growth. The ratio of concentrated feed and roughage directly affects the dry matter intake, rumen function, feed remuneration, production performance and health level of reared animals. [0003] The existing feed screening mechanism needs to be shut down to clean the screen after running for a period of time to remove large particles of impurities on the surface of the screen, which affects its screening efficiency.
