Drying and screening device for agricultural cereals

Abstract

The invention discloses a drying and screening device for agricultural cereals. The drying and screening device for agricultural cereals comprises a main body, a power box and a heating box. The rightend of the left wall of the power box is fixedly connected to the left end of a motor, the right end of an output shaft of the motor is fixedly connected to a sleeve, the right end of the output shaft of the motor is fixedly connected to a first transmission wheel on the right side of the sleeve, the first transmission wheel is connected to a second transmission wheel and a third conveyor belt through a conveyor belt, separately, the second transmission wheel is arranged at the left end of a first rotating rod, the right end of the first rotating rod s connected to one end of a hinge plate, spiral blades are arranged on the sleeve, the sleeve is arranged in the supporting plate, the left end of the supporting plate is fixedly connected to the inner surface of the left wall of the main body, and the third conveyor belt is fixedly connected to the right end of a second rotating rod. The drying and screening device for agricultural cereals disclosed by the invention is energy-saving, candry agricultural cereals for three times simultaneously, is high in drying efficiency, can adjust the discharging speed of agricultural crops, and is high in practicality and suitable for being popularized.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a drying and screening device for agricultural grains. Background technique [0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. The objects of labor in agriculture are living animals and plants, and the products obtained are the animals and plants themselves. Agriculture is the basic industry that provides support for the construction and development of the national economy.

Problems solved by technology

As we all know, the key to safe grain storage is to reduce the water content in the grain to reduce the occurrence of mildew; however, the freshly harvested grain has high water content and high surface humidity, even if the farmers store the surplus grain for a short time before it is sold, it is inevitable. Grains germinate or become moldy due to heat and humidity; this not only causes farmers to suffer losses, but moldy grains and their processed foods, once they enter the market, will endanger the health of more people;

[0003] The existing grain drying device is relatively complicated as a whole. It can only dry agricultural grain once, and the drying efficiency is low. Moreover, agricultural grain is often dried unevenly, resulting in incomplete local drying, which does not meet the needs of existing processing and production. Greatly increased the labor intensity of workers; at the same time, the dry hot air is directly discharged, resulting in waste of heat
