Grain screening and drying device

Abstract

The invention discloses a grain screening and drying device. The grain screening and drying device comprises a drying assembly, a screening assembly and a lifting device; the screening assembly is used for screening grains and separately placing and temporarily storing the grains; the drying assembly is used for drying the screened grains; the dried grains enter a storage bin or are lifted to thescreening assembly by the lifting device for secondary treatment; and the drying assembly, the screening assembly and the lifting device are all arranged on a machine base. The grain screening and drying device has the good sealing property, so that dust in rice is prevented from polluting a surrounding environment and affecting the health of workers. According to the grain screening and drying device, five shunting pipes are arranged below a feeding bin to separately treat and screen rice, and are matched with three buffer grids and screens, so that the rice is capable of being screened morethoroughly; the drying assembly of the grain screening and drying device is internally provided with a shunting mechanism, so that the drying is more sufficient; and the grain screening and drying device is provided with a switching device, in other words, the direction of the grains is controlled through a plug, so that the grain screening and drying device is free and flexible.

Description

technical field [0001] The invention belongs to the technical field of grain production equipment, and in particular relates to a grain screening and drying device. Background technique [0002] Drying is an important way to store grain. If the grain is not dried, it will cause mold and rot.

[0002] Drying is an important way to store grain. If the grain is not dried, it will cause mold and rot. The existing drying and screening equipment often pollutes the working environment during the work process. For example, the application number is 201811004269.1, and the publication number is CN109261521A The Chinese patent "a rice drying and screening device" discloses: a rice drying and screening device, including a lifting bin, a movable bottom plate is arranged at the bottom of the lifting bin, a lifting mechanism is also arranged inside, and a lifting bin is arranged on the top of the lifting bin The outlet of the lifting chamber is matched with the inlet of the drying and screening chamber. The inside of the drying and screening chamber is equipped with a first screening fan and a second screening fan in sequence, and a split flow matching with the second screening fan is also provided in the middle of the interior. Slope, the two sides of the diversion slope are respectively equipped with a drying feed inlet and a screening pipeline, a vibrating drying plate is installed under the drying feeding inlet, and a drying fan is arranged on the left side of the vibrating drying plate, and a drying and screening bin is installed. The bottom is provided with a return pipe and a finished product pipe. The screening pipe is connected with a dust pipe and a crushed leaf pipe. The dust pipe leads to the sewage collection tank. The screening and drying degree of the device is average
