Rice dryer with good drying effect and high screening rate

Abstract

The invention relates to a rice dryer with a good drying effect and a high screening rate. The rice dryer comprises a pedestal, a feeding chamber, a drying chamber, a storage chamber, a feeding funnel, a conveying pipeline, a solenoid valve, a feed delivery pipe and an air blower, wherein the drying chamber is internally provided with a first guide block, a second guide block and a transportationmechanism, the drying chamber is internally provided with a grid tray, a heating unit, a drying mechanism and a horizontal paving mechanism, the drying mechanism comprises a speed changing component,a driven wheel, a revolving shaft, a limiting plate, a regulation component, two fan blades and two limiting rods. According to the rice dryer with the good drying effect and the high screening rate,the quantity of rice which enters the feeding chamber is controlled by the transportation mechanism and a pressure sensor, so that the rice which enters the drying chamber is convenient to pave horizontally and uniformly, the wind power can be adjusted by the drying mechanism, so that the rice dryer is suitable for screening rice with different weights, the rice can be more uniformly and horizontally paved on the grid tray through the horizontal paving mechanism so as to enable rice to be heated more uniformly, so that the practicability of the rice dryer is improved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a rice dryer with good drying effect and high screening rate. Background technique [0002] Agricultural machinery refers to various machinery used in crop planting and animal husbandry production, as well as in the primary processing and handling of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland drainage and irrigation machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, etc. The rice dryer is a kind of agricultural product processing machinery, which is a machine for drying rice. [0003] When the existing rice dryer is fed, the amount of rice entering the drying chamber is not easy to control, and...

AI Technical Summary

Problems solved by technology

[0003] When the existing rice dryer is fed, the amount of rice entering the drying chamber is not easy to control, and the distribution of rice entering the drying chamber is uneven, resulting in uneven heating of the rice during drying, and uneven drying degree, which makes The overall drying efficiency is reduced, and taking out the rice in advance in order to save time reduces the drying effect of the existing rice dryer. Not only that, the existing rice dryer has a constant wind force when screening shriveled grains, which is not convenient for drying Different weights of rice are screened, thus reducing the screening rate of the existing rice dryer
