Embodiment Construction

[0016] The technical content of the invention will be further described below in conjunction with the accompanying drawings.

[0017] On the slightly inclined rolling cage bracket 11, a grid-shaped rolling cage 1 with several layers of cylinders overlapping each other from the inside to the outside is designed. The grid gap of the roller cage 4 is designed according to the classification standard of hairy crabs. The gap between the grid gaps changes from the inner layer roller cage 4 to the middle layer roller cage 3 and the outer layer roller cage 2. The upper end of the roller cage 1 The opening of the innermost rolling cage 4 is movably connected to the hairy crab feeding port 5, and the feeding port 5 is designed with a control baffle 12, and the opening of the inner rolling cage 4 at the lower end of the rolling cage 1 is movably connected to the inner layer receiving device 8, The mouth of the middle layer roller cage 3 is movably connected to the middle layer material r...

Abstract

The invention discloses hairy crab grading equipment. A multi-layer grid cylindrical rolling drum with two ends communicated is designed on a rolling drum support, the multiple layers of the rolling drum sleeve one another from inside to outside, and the rolling drum is inclined slightly. Grid gaps of each layer of the rolling drum are designed according to hairy crab grading standards, grid gap intervals are narrowed layer by layer from inside to outside, an innermost opening of the upper end of the rolling drum is movably connected with a hairy crab feeding port which is provided with a control baffle, and openings in the lower end of the rolling drum are movably connected with grading receiving devices respectively. The rolling drum is connected with a rotating shaft of a motor through a transmission device.

Description

[0001] Field [0002] The invention belongs to the field of aquatic product sorting, and in particular relates to grading and screening equipment for hairy crabs. Background technique [0003] Hairy crabs are greenish-yellow in color, fresh and tender in texture, delicious in taste and rich in nutrition. In recent years, they have become a delicacy on people's tables, and the domestic demand is increasing year by year. The annual "China Sihong Crab Festival" is not only held in many cities in China, but also abroad. The breeding and processing of hairy crabs in Taihu Lake, Hongze Lake and Yangcheng Lake has developed into an important industry of aquatic products in my country. [0004] The size of a single head of fresh and live hairy crabs is the key to determining the purchase price, and it is also the basis for product classification of wholesale and retail enterprises. The enterprise imports and exports dozens of tons of hairy crabs every day. Due to the different sourc...
