Rotary type rice drying and screening device

Abstract

The invention provides a rotary type rice drying and screening device. The rotary type rice drying and screening device comprises a lifting bin, a movable bottom plate is arranged on the bottom of thelifting bin, a lifting mechanism is arranged in the lifting bin, a lifting bin outlet is formed in the top of the lifting bin, a first filter screen is arranged under the lifting bin outlet, and a screening blower and a sorting slope are arranged below the first filter screen. A drying bin is arranged below the filter screen, a drying cavity is formed in the drying bin, an annular gear is installed on the drying bin, and the annular gear is matched with a rotary gear. A bottom drying blower is arranged on the bottom of the drying cavity, a plurality of peripheral drying blowers are uniformlyarranged around the drying bin, the sorting slope is connected with a screening pipeline, the tail end of the screening pipeline is communicated with a division pipeline and a dust collection pipeline, a second filter screen is arranged at the communication position of the dust collection pipeline and the screening pipeline, and a dirt collection pond is arranged at the tail end of the dust collection pipeline, so that impurities in rice are filtered in the drying process of the rice, dust in the rice is precipitated, and contaminations are effectively reduced; due to rotation of the drying bin, drying is more uniform; due to the drying cavity, the heating area of the rice is increased, the drying efficiency is improved, and the drying quality is improved.

Description

technical field [0001] The invention belongs to the technical field of grain production equipment, and more specifically relates to a rotary rice drying and screening device. Background technique [0002] Rice drying is a very important process in rice production. If rice is not dried, it is easy to mold and cause a lot of economic losses. Generally, rice drying only adopts a drying method, and the process of rice drying In the same drying area, a large amount of rice is piled up, heated and dried unevenly, and the rice inside cannot be dried, so the drying effect and efficiency are not high. The leaves are broken and mixed into the rice, which makes the rice removal more troublesome. If it is not removed, it will affect the quality of the rice processed from the rice. At the same time, a large amount of dust will adhere to the rice during harvesting and threshing. The existing drying process does not deal with the dust, which will cause the dust to enter the air and cause ...

Generally, rice drying only adopts a drying method, and the process of rice drying In the same drying area, a large amount of rice is piled up, heated and dried unevenly, and the rice inside cannot be dried, so the drying effect and efficiency are not high. The leaves are broken and mixed into the rice, which makes the rice removal more troublesome. If it is not removed, it will affect the quality of the rice processed from the rice. At the same time, a large amount of dust will adhere to the rice during harvesting and threshing. The existing drying process does not deal with the dust, which will cause the dust to enter the air and cause a certain degree of pollution to the air. At the same time, when the workers are bagging the rice, the dust in the rice will cause damage to the worker's body
