Description

Technical Field

[0002] Feed is a general term for food for animals raised by all people. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Before the production and processing of feed, the raw materials need to be screened and filtered to avoid the raw materials used for feed production being mixed with impurities during harvesting or drying, which may cause damage to livestock animals when used for feeding. Existing equipment usually uses screening to remove impurities, but it cannot clean the dust contained in the raw materials. When used for feed processing, it will not only have a negative impact on the quality of the feed, but long-term feeding may also affect the health of livestock animals and reduce the practicality of the device.

[0003] After searching, for example (authorization announcement number CN217550446U) a feed screening device for feed processing is pushed by a cylinder through a push plate, and the push plate is attached to the surface of the screen, so that when impurities accumulate on the surface of the screen, the cylinder pushes the push plate to squeeze the impurities into the impurity discharge port and discharge them from the screen barrel; through the setting of the fine filtering component, impurities smaller than the feed can also be effectively filtered; through the setting of the dust suction component, the dust floating during screening can be quickly and effectively processed; through the setting of the guide plate, large particles of impurities will not fall to the collection port and collection barrel below; through the setting of the triangular guide block, the feed is prevented from falling into the bottom trough below. This device solves the problem that the existing equipment needs to stop the machine to clean the filter, but the device cannot remove dust from the raw materials used in feed production, reducing the practicality of the device.
