Abstract
Description
Technical Field
[0001] This utility model relates to the field of flaxseed production technology, and in particular to a high-efficiency automatic screening device for flaxseed waste. Background Technology
[0002] To address the issues of harmful organisms carried by imported flaxseed raw materials and low utilization rate of flaxseed meal, impurities from imported flaxseed after screening are mixed with flaxseed meal, a byproduct of cold pressing. After screening, the mixture is separated into plant-based byproducts and non-plant-based byproducts. Based on the different properties of the byproducts, they are subjected to harmless treatment and high-value harmless processing.
[0003] However, existing technologies still have shortcomings. They are not efficient at screening waste materials and cannot collect non-plant waste materials, requiring manual secondary collection.
[0004] Therefore, we propose a high-efficiency automatic screening device for flaxseed waste to solve this problem. Utility Model Content

[0009] Preferably, the inner groove is located on one side of the mounting shell; the fixing block is a trapezoidal block.
[0010] Preferably, one end of the spring is fixed to the inner surface of the connecting block; the fixing block and the fixing groove cooperate with each other.
[0011] Preferably, the mounting bracket is located on one side of the feed hopper; the mesh size of the second filter screen is greater than that of the first filter screen.
[0012] This invention discloses a high-efficiency automatic screening device for flaxseed waste. Through the arrangement of a shell, support, discharge hopper, mounting shell, fan, fixing frame, feed hopper, inner groove, first filter screen, connecting shell, second filter screen, connecting frame, collection shell, connecting block, fixing groove, second sliding groove, fixing block, and spring, the waste is fed into the feed hopper. The fan is activated, blowing air through the waste to screen it. Non-plant waste is blown into the connecting shell, while plant waste is intercepted by the first filter screen and non-plant waste by the second filter screen. Then, under their own gravity, they enter the collection shell, where non-plant waste is collected. Plant waste is discharged through the discharge hopper under its own gravity. When the collection shell is removed, the fixing block is pushed out of the fixing groove. Once the fixing block is completely removed from the fixing groove, the collection shell can be removed. This achieves rapid screening and collection of flaxseed waste, improving efficiency.

Through the arrangement of a first chute, a sealing plate, a mounting frame, a threaded rod, and a rotating block, the rotation of the rotating block will drive the threaded rod to rotate, and the rotation of the threaded rod will drive the sealing plate to move. The movement of the sealing plate will adjust the discharge port of the feed hopper, thereby adjusting the discharge speed.
