Description

Screening device for grain purchase Technical Field The utility model relates to the technical field of screening devices, in particular to a screening device for grain acquisition. Background The grains refer to the total name of various plant seeds in the cooked food, and can be also referred to as grains in summary, the grain crops contain rich nutrients, mainly proteins, vitamins, dietary fibers, fat, starch and the like, and the grains are often screened by a screening device before purchasing. Traditional screening plant is simple just jolt the grain under a few to do not reach efficient screening effect, often jolt the back with the grain, the surface of grain still has the dust, and can not handle the dust on grain surface, often still need follow-up dust removal process, take up an artificial effort, reduced the efficiency of grain screening. Therefore, a screening device for grain acquisition is proposed to solve the above problems. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a screening device for grain acquisition, which has the advantage of improving grain screening efficiency and solves the technical problem that dust on the surface of grains cannot be effectively treated. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a grain is purchased and is used sieving mechanism, includes the screening case, screening case top is provided with the feed inlet, screening case one side is provided with the dust exhaust pipe, the dust exhaust pipe is located screening case inside top, screening case inside top is provided with the toper subassembly, the toper subassembly is fixed through the connecting rod screening case inside, the toper subassembly includes little toper piece, little toper piece below is connected with big toper piece the toper subassembly below is provided with vibration mechanism, screening case bottom is provided with the bin outlet. Further, a first driving part is arranged in the large conical part, and an output end of the first driving part is connected to the bottom of the small conical part. Further, the vibrating mechanism comprises a fixing piece with a through hole in the middle, the vibrating screen is connected to the fixing piece in a sliding mode, and a driving mechanism for driving the vibrating screen to rotate back and forth is arranged on the fixing piece. Further, the actuating mechanism is including fixed setting driving piece two on the mounting, fixedly connected with incomplete gear on the driving piece two, the shale shaker periphery be provided with incomplete gear engagement's gear ring, the shale shaker bottom is provided with the vibrations piece, and the mounting upper surface is provided with the ring channel relatively, fixedly connected with connecting piece on the vibrations piece, and the connecting piece both ends are provided with the spring respectively. Further, a door body is arranged on the outer side of the screening box. Compared with the prior art, the device has the beneficial effects that the device has the advantages that the conical assembly is arranged in the screening box, grains sequentially impact the small conical part and the large conical part in the conical assembly after being thrown into the screening box through the feeding hole, dust attached to the surface of the grains is lifted through impact and discharged through the dust discharging pipe, the device can effectively treat the dust on the surface of the grains, the subsequent dust removing process is saved, and the grain screening efficiency is improved.
