Agricultural grain dryer

Abstract

The invention discloses an agricultural grain dryer. The agricultural grain dryer comprises a base and dampers, wherein the dampers are arranged at the lower end of the inner part of the base; the base is connected with the dampers through welding; a compressing cylinder is arranged at the upper ends of the dampers; an electric motor is arranged at the right end of the compressing cylinder; and aconveying belt is arranged at the upper end of the electric motor. According to the agricultural grain dryer disclosed by the invention, a screen mesh is arranged in a feeding funnel, so that impurities including metal articles, small sand blocks, minced plastics and the like can be blocked and discharged from an impurity removing opening, the situation that the impurities enter the grain dryer, and parts and components in the agricultural grain dryer are damaged is avoided, and the using service of the agricultural grain dryer is prolonged; and besides, a pipe frame of the agricultural graindryer adopts heat dissipation ribs made from carbon fibers, so that on one side, infrared heating pipes can be effectively protected, the situation that the infrared heating pipes fall down because ofvibration is avoided, and on the other side, heat quantity of the infrared heating pipes is uniformly dissipated to the peripheries of the heating pipes.

Description

technical field [0001] The invention belongs to the related technical field of grain drying equipment, and in particular relates to an agricultural grain drying machine. Background technique [0002] A mechanical device that uses thermal energy to reduce the moisture content of materials and is used to dry objects. The dryer evaporates the moisture in the material by heating to obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. In the main grain producing areas, due to the large output and insufficient drying space, the grain purchased by the grain depot often exceeds the safe moisture content, which is the main factor leading to grain mildew. [0003] The existing drying machine technology has the following problems: the existing drying machine vibrates greatly, and the infrared heating tube is prone to fall off. When working, because the materials are poured into the dryer, the grai...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an agricultural grain dryer to solve the problem that the existing dryer proposed in the above background technology has a large vibration, and the infrared heating tube is easy to fall off, and at the same time, the infrared heating tube needs to be disassembled when replacing it. The seat heads at both ends of the machine are time-consuming and labor-intensive, and because the materials are poured into the dryer during the work, because the grains are mixed with impurities, this will lead to the problem of damaging the service life of the machine
