Separating speed adjustable type circulating grain drying machine

Abstract

The invention discloses a separating speed adjustable type circulating grain drying machine which comprises a grain storing cabin, a feeding hoister, a feeding hopper hoister and a drying system, wherein the feeding hoister and the feeding hopper hoister are mounted on two sides of a grain storing cabin base; the drying system is mounted below the feeding hopper hoister and comprises a fixed rack,a feeding elephant trunk, a discharging elephant trunk, a hot-blast air inlet connecting pipe, an air outlet pipe, a fixed coaming and a drying device; the fixed coaming is mounted around the dryingdevice; the drying device comprises a driving motor, a driving sprocket, a pulling chain, a porous screen plate and a heat-resisting rubber flexible plate; and grain in the grain storing cabin is controlled by a discharging gate to enter the feeding hopper hoister, enters into the drying device to be dried on the drying system via a feeding pipe, is conveyed to the discharging elephant trunk to bedischarged, and enters the grain storing cabin via a grain feeding pipe through the feeding hoister. According to the technical scheme, the separating speed adjustable type circulating grain drying machine is simple in structure and safe and reliable; a grain storing layer, a drying layer and a transportation device are designed in a separating manner, so that secondary loss of grain is avoided;and the separating speed adjustable type circulating grain drying machine is convenient in mounting and overhaul and uniform in heating, improves the drying quality and reduces energy consumption andfailure rate.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a separate adjustable speed circulating grain dryer. Background technique [0002] In order to prevent the grain from becoming moldy and deteriorating, it needs to be dried in time before entering the warehouse. With the rapid development of social science and technology, in addition to the natural method of using sun exposure, many different drying equipment have appeared on the market. The existing grain dryer is a dryer assembly, mainly composed of a grain circulation system, a drying layer, a grain storage layer, a dust removal system, and an electric control system. Among them, the feeding of the screw machine in the grain circulation system is easy to cause the grain to be broken. Adding a drive motor will increase the energy consumption and increase the failure rate; the drying layer is a material flow channel formed by multiple mesh plates, which makes the grain...

Problems solved by technology

Among them, the feeding of the screw machine in the grain circulation system is easy to cause the grain to be broken. Adding a drive motor will increase the energy consumption and increase the failure rate; the drying layer is a material flow channel formed by multiple mesh plates, which makes the grain cycle heated Drying has high requirements on the anti-wear ability of the grid plate, guarantees the life, high cost, and inconvenient maintenance; any failure of each system requires time-consuming waiting for maintenance, which wastes time and increases the probability of secondary losses
