Material circulating dryer base with non-viscous discharging and conveying function

Abstract

The invention discloses a material circulating dryer base with a non-viscous discharging and conveying function. A discharging mechanism is arranged below an outlet in the bottom of a collecting hopper, a vibration soil screening mechanism is arranged below the discharging mechanism, soil and impurities are discharged from a soil and impurity output port of the vibration soil screening mechanism, enter a soil and impurity removal output mechanism and are output out of a rack side by side, and up-to-standard peanut materials are discharged from a discharge port of the vibration soil screening mechanism; hot air in an air inlet pipe on the rack is introduced into a first air duct through an air inducing pipe, is discharged from the bottom of the first air duct, sequentially passes through an inner cavity of the collecting hopper and a second air duct on the side wall of the collecting hopper, and then is discharged out of the rack from the lower part of the second air duct through an air outlet pipe; the second air duct is positioned between the inner wall and the outer wall of the collecting hopper; and when a vibration motor of the vibration soil screening mechanism works, vibration is transmitted to an elastic finger screening surface unit, and then the soil, the impurities and the up-to-standard peanut materials in the materials are screened out. The structure is exquisite, materials near the wall face of the collecting hopper at the bottom of a dryer can be prevented from being compacted and detained when the materials containing the soil and the impurities are dried, and the drying quality is improved.

Description

technical field [0001] The invention belongs to material drying treatment technology, in particular to a base of a material circulation dryer with non-viscosity discharge function. Background technique [0002] At present, peanut materials for large-scale planting and harvesting generally have the characteristics of high soil trash content and easy compaction after compaction. In order to solve these problems, there are some corresponding dryers on the market, but these dryers still have the following defects: [0003] (1) During the drying operation of some dryers, after the materials (peanuts and soil impurities) at the bottom collecting hopper are compacted and hardened, the materials close to the wall of the collecting hopper have poor fluidity, and a large amount of them will stay on the wall of the collecting hopper for a long time. Lack of ventilation causes mildew; [0004] (2) Due to the open bottom material discharge and soil conveying mechanism used by some dryer...

Problems solved by technology

[0002] At present, peanut materials for large-scale planting and harvesting generally have the characteristics of high soil trash content and easy compaction after compaction. In order to solve these problems, there are some corresponding dryers on the market, but these dryers still have the following defects:

[0003] (1) During the drying operation of some dryers, after the materials (peanuts and soil impurities) at the bottom collecting hopper are compacted and hardened, the materials close to the wall of the collecting hopper have poor fluidity, and a large amount of them will stay on the wall of the collecting hopper for a long time. Lack of ventilation causes mildew;

[0004] (2) Part of the dryer adopts an open-bottom material discharge and soil conveying mechanism, which causes a lot of dust during its operation, causing serious environmental pollution, which is time-consuming and labor-intensive
