Description

A kind of de-burring machine

Technical field

A kind of de-burring machine is the utility model is related to, belongs to cereal processing and technical field is set.

Background technology

In food service industry, when making the food such as grain powder, cleaning removal need to be carried out to the impurity in grain.Grain Impurity in such as rapeseed, cereal is broadly divided into big impurity, medium impurity and small impurity part.And generally use blower fan at present The removal of impurities mode of formula is removed or screen mesh type is handled.But the principle mainly utilized using fan type be according to grain with it is miscellaneous Weight difference between matter controls wind-force to reach the purpose of separation, and this separate mode may be only available for grain of the part than relatively lightweight Edible material carries out removal of impurities and has preferable effect, and still, the removal for the quite much the same impurity of weight is equivalent to difficulty. And for example Chinese patent (Authorization Notice No.：CN205772133U a kind of vibrating shaker hopper) is disclosed, it includes hopper body, institute The bottom for the hopper body stated is provided with discharging opening, and large aperture screen cloth, aperture are sequentially provided with from top to bottom in described hopper body Hopper body is divided into primary storage cavity, storage cavity and fine impurities and stored up by footpath screen cloth, described large aperture screen cloth, small-bore screen cloth Three parts of chamber are hidden, the bottom of described primary storage cavity is provided with primary impurity discharging port, and described fine impurities storage chamber bottom is set There is impurity discharging port.Although its by in-between be provided with different size aperture screen cloth, can realize to a certain extent by The removal of big impurity and small impurity, still, because it is directly to be separated from bottom with grain materials when handling small impurity, separation Interval is too short, can only be miscellaneous except removal by the part on surface, and is difficult the separation for the impurity for effectively removing centre, and separates and imitate Fruit is poor.

The content of the invention

The utility model a kind of de-burring machine, solves the problems, such as it how real is for defect present in above prior art Now improve the impurity in fully filtering grain.

The purpose of this utility model technical scheme is that, a kind of de-burring machine, including frame, vibration Device and the sieve lattice provided with screen cloth, the vibrator are arranged in frame, and elastic component is provided between the vibrator and frame, described Vibrator is fixed on the bottom of sieve lattice, it is characterised in that the outlet side of the sieve lattice is provided with secondary filter structure, the secondary mistake Filter structure includes fixed seat, agitating shaft and the drive mechanism being fixed in frame, and the upper end of the fixed seat is provided with feed hopper one, The feed hopper one is below the port of export of sieve lattice；The side of the fixed seat is provided with cartridge filter, and the cartridge filter is horizontal It is set on agitating shaft, the port of export of the feed hopper one is connected with cartridge filter, and the outlet side of the cartridge filter is provided with storing Lattice；The agitating shaft is rotatably arranged in fixed seat, and the drive mechanism can drive agitating shaft to rotate, outside the cartridge filter Provided with protective cover, the lower section of the protective cover has discharging opening, and the lower section of the discharging opening is provided with debris lattice.

By the way that first using the sieve lattice with screen cloth in the presence of vibrator, the separation of big impurity is preselected on screen cloth Remove, then, then grain materials is carried out cartridge filter into secondary filter structure by vibrating transportation and carry out secondary filter removal The impurity part smaller than grain materials itself, and due under the rotation of agitating shaft can fully to enter cartridge filter in grain Material plays stirring action, makes also can fully divided the small impurity of inside when accumulating during removing small impurity From；Simultaneously as cartridge filter is using laterally setting, this makes it possible to improve grain materials to have the sufficient time in cartridge filter Separate removing, the effect for removing small impurity is sufficiently separated so as to realize, and the impurity separated is put into the debris of lower section In lattice, meanwhile, the grain materials after removal of impurities is transported in the storing lattice of filter cartridge outlet side-lower.
