Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of feed extrusion, and particularly relates to a feed production extrusion device. BACKGROUND

[0002] Fish and shrimp feed molds are designed according to the mouth shape and feeding habits of aquatic animals, and have various pore diameters and shapes, such as circular, square, or ring-shaped. The mold material is usually durable stainless steel or alloy to resist wear and corrosion during feed processing. Using the appropriate mold can improve the molding rate of the feed, reduce production costs, and ensure the uniformity and stability of the feed particles, which helps to improve the feeding efficiency and growth performance of aquatic animals.

[0003] The existing public patent, with the publication number CN220559160U, discloses a feed production extrusion device, which includes a base, an extrusion mechanism, and a crushing mechanism. The base has an extrusion mechanism on the upper inner wall, and the extrusion mechanism is fixedly connected with a crushing mechanism on the upper side.

[0004] When the extrusion device is in use, the crushing mechanism will continuously feed the main tank. At the same time, when the pressing plate is pressed down under the action of the hydraulic rod, it will still feed the main tank. As a result, the feed will fall on the upper side of the pressing plate and cannot fall down. After a long time of use, when the pressing plate is reset upward for recovery, the accumulated feed will cause the hydraulic rod to be unable to reset and be stuck, reducing the service life of the equipment.
