Embodiment 1

[0038] A multifunctional grain dryer, including a support system, a power system and a multifunctional drying system; the support system includes a base 7 and two pillars 5 installed on the base 7; the power system includes a 10 above the motor 11 and transmission system 12; the multifunctional drying system adopts a double-tube structure, including an outer cylinder 1 fixed on the pillar 5 and a drying cylinder installed in the outer cylinder 1; the bottom of the outer cylinder 1 An outer cylinder outlet 9 is arranged in the center, and an outer cylinder inlet 15 is arranged at the top; an air inlet 6 is arranged at the foot of one side of the outer cylinder 1, and an air outlet 13 is arranged at the top corner of the other side; The opening of the air inlet 6 is horizontally downward; the drying cylinder includes a cylinder 2 with a screen hole on the cylindrical surface, a sieve plate 3 and two shafts 4 fixed at both ends of the cylinder 2 and connected to the pillar; the si...

Embodiment 2

[0040] Based on Embodiment 1, in order to optimize the balance between the negative pressure effect generated by the air flow and the screening effect of lighter impurities, the following improvements were made: the acute angle between the central axis of the air inlet 6 and the straight line where the bottom edge of the outer cylinder 1 is The tangent is equal to the ratio of the diameter to the length of the cylindrical surface of the outer cylinder.

[0041] After repeated tests and verification, when the acute angle between the central axis of the air inlet and the straight line where the bottom edge of the outer cylinder is located is the above ratio, it is not only conducive to the extraction of humid air in the drying cylinder, but also ensures the drying effect; Insufficient air flow on the lower surface of the cylinder and the insufficient negative pressure formed result in the backflow of light impurities such as dust and dry broken leaves, which ensures the effect of...

Embodiment 3

[0043] Based on Example 1, in order to optimize the removal effect of attached impurities and the effect of stirring and dispersing grain particles, the following improvements were made: the sieve plate 3 is provided with a single-shaped sieve hole; the sieve hole is a rhombus mesh.

[0044] When a diamond-shaped mesh is designed on the sieve plate, with the rotation of the drying cylinder, the grain particles at a high place are blocked by the sieve plate, and when they slide and roll down on the sieve plate, part of the grain particles flow along the diamond-shaped mesh. Some of the holes fall down, and the other part continues to roll down along the sieve plate. In this way, the further dispersion of the grain particles is realized, the overall heating area and heating uniformity of the grain particles are improved, and the drying effect of the grain particles is improved.

Abstract

The invention relates to a multifunctional grain dryer which comprises a support system, a power system and a multifunctional drying system. The multifunctional drying system adopts a double-cylindertype structure and comprises an outer cylinder fixed onto support pillars, and a drying cylinder arranged in the outer cylinder; an outer cylinder discharge hole is formed in the center of the bottompart of the outer cylinder; an outer cylinder feed inlet is formed in the top part of the outer cylinder; an air inlet is formed in a bottom leg on one side; an air outlet is formed in a top angle onthe other side; the drying cylinder comprises a cylinder body with sieve pores in a cylindrical surface, sieve plates and two shaft rods fixed to two ends of the cylinder body and connected with the support pillars; one end of each sieve plate is fixed onto an inner wall of the cylinder body; a certain clearance is left between the other end of each sieve plate and the inner wall of the cylinder body; an inner cylinder discharge hole is formed in the bottom part of the cylinder body; an inner cylinder feed inlet is formed in the top part of the cylinder body; and any one shaft rod is connectedinto a drive system. The multifunctional grain dryer not only has an excellent drying effect, but also can be used for synchronously screening impurities, has the characteristics of simple structure,lower manufacturing cost, convenience in operation and easiness in maintenance, and has remarkable economic benefit and popularization value.

Description

technical field [0001] The invention relates to the field of grain drying equipment, in particular to a multifunctional grain drying machine. Background technique [0002] Food is the most important thing for the people, and food is the foundation of the people's livelihood, and it has always been one of the country's important strategic war preparation materials. However, as a plant product, it has a growth cycle itself, and this growth cycle is affected by many climate and human factors including temperature, rain, soil, manpower, etc. If the growing environment is good, the yield will be good; if the growing environment is poor, there may be no harvest. This is the sharp contrast between "rich chickens and pigs" and "knowing me like this, it is better to have no life". As a strategic combat readiness material, it must be able to be stored and saved for a long time to deal with any possible emergency, so as to meet the living needs of the people and maintain the stability...
