Problems solved by technology

However, the existing coffee grinder mainly utilizes an extrusion device to squeeze the coffee beans into pieces
During the operation of this structure, coffee beans are easy to adhere to the working surface of the extrusion device. The extrusion device continues to operate, and the more coffee beans adhere to the working surface, the final result is that the extrusion effect is not good.

Abstract

The invention belongs to the field of grinding technology, and especially relates to a coffee grinding device. The coffee grinding device comprises a grinding cavity, a rotating shaft, spiral blades, and a throwing plate; the grinding cavity is a cylindrical cavity; the rotating shaft is arranged in the grinding cavity; the spiral blades are fixedly arranged on the rotating shaft; the throwing plate is connected with the lower end of the rotating shaft in radial direction; the length of the throwing plate and the interior diameter of the grinding cavity are the same; the lower end surface of the throwing plate is contacted with the bottom surface of the grinding cavity; the surfaces of the spiral blades are provided with a plurality of tapered cutter teeth at uniform intervals; and the points of the tapered cutter teeth are arranged outward. According to the coffee grinding device, coffee beans are delivered into the grinding cavity; the rotating shaft is driven to rotate by an external powder device; the coffee beans are cut by the spiral blades arranged on the rotating shaft, and the tapered cutter teeth of the spiral blades; more coffee beans are cut via double cutting; and working efficiency is increased. In addition, because of gravity action, coffee beans may fall to the bottom of the grinding cavity, the throwing plate rotates with the rotating shaft, and then the coffee beans at the bottom are thrown out for further grinding.

Description

technical field [0001] The invention belongs to the field of crushing devices, in particular to a coffee grinding device. Background technique [0002] The existing coffee beans are mainly sold in two ways: one is to process them into powdered finished products (three-in-one coffee), and the other is to break the coffee beans into small particles, which is mainly convenient for shipment and convenient for coffee machines. secondary grinding. But existing coffee grinder mainly utilizes extruding device to squeeze, and coffee bean is broken into pieces. During the operation of this structure, coffee beans are easy to adhere to the working surface of the extruding device, and the extruding device continues to operate, and the more coffee beans adhere to the working surface, the final result is poor extrusion effect. Contents of the invention [0003] The technical problem solved by the invention is that the existing coffee grinder mainly utilizes an extruding device for ext...
