Mechanical crushing device for rapeseed grains

Abstract

The invention discloses a mechanical crushing device for rapeseed grains. The mechanical crushing device comprises a feeding channel, scrapers and a crushing cavity, the crushing cavity is formed in the bottom of a mechanical crushing device body, a left grinding roller and a right grinding roller are arranged in the crushing cavity, the two scrapers are arranged on the side walls of the left sideand the right side of the crushing cavity separately, the feeding channel is formed in the position, on the upper side of the crushing cavity, inside the mechanical crushing device body, a pressing plate is inserted into the feeding channel, an annular baffle is fixed to the upper end of the pressing plate, a fixing rod is arranged at the center position of the upper end of the pressing plate, arotating rod is hinged to the upper end of the fixing rod, and the upper end of the rotating rod is fixed to the eccentric position of a rotating disc in a rotating mode through a fixing shaft. The mechanical crushing device for the rapeseed grains has the advantages that the rapeseed grains can be rapidly and efficiently crushed, the problems that the rapeseed grains are prone to slide and are not liable to be crushed, the speed is low, and the efficiency is low due to the fact that no pressing plate presses the rapeseed grains downwards can be solved,and meanwhile, the scrapers are arranged,so that the phenomenon that crushing of the rapeseed grains is influenced due to the fact that the rapeseed grains adhere to the surfaces of the left grinding roller and the right grinding roller canbe avoided.

Description

technical field [0001] The invention relates to a crushing mechanical device, in particular to a rapeseed crushing mechanical device. Background technique [0002] Rapeseed, also known as brassica seed, is a herbaceous cruciferous crop, one of the main oil crops and nectar crops in my country, and its seeds are one of the main varieties of raw materials for making oil. Rapeseed oil is commonly known as rapeseed oil, also known as coriander seed oil, which is a transparent or translucent liquid obtained by pressing the seed rapeseed of the cruciferous plant Brassica (ie rapeseed). Generally dark yellow or brown. Rapeseed oil contains 0.4-1.0% arachidic acid, 14-19% oleic acid, 12-24% linoleic acid, 31-55% erucic acid and 1-10% linolenic acid. From the perspective of nutritional value, the human body can digest and absorb rapeseed oil as high as 99%, and it has a gallbladder function. Therefore, rapeseed oil is the main dietary oil for consumers in my country. Its quality i...

Problems solved by technology

[0004] The structure of rapeseed is spherical, and the outer shell is hard. The current rapeseed crusher crushes and crushes rapeseed through rollers, but because of the structure of rapeseed, when rolling, the rapeseed is easy to slide and not easy to break, and the efficiency is too slow, and It is easy to stick to the roller, causing the rapeseed to be too fragmented, and greatly slowing down the crushing speed
