Abstract

The invention is a type of grain dryer. Which mainly consists of Machine body, multiple hot air ducts Multiple air ducts And a stack of grains of grains All of which were Built in the lower half of the machine using a net Conveying equipment, which may transport certain volumes Sleep of whole grains from a trough stack of whole grains And transport the grains to the top of the machine and let the grains fall evenly. Hot air generating equipment consisting of The exhaust fan and hot air generator are connected respectively to the intake ducts and hot air ducts arranged side. In the machine The main feature of this invention is that a mechanism for swaying air direction was provided. The output side of the hot air generator to make the hot air blowing more uniform. In addition, by Together with the relevant equipment of the conveying device and the mesh sheet of this invention Make improvements Effectively to promote drying efficiency. And there is a constant drying and reducing the rate. Damage and achieve the purpose of practical application.

Claims (6)

1. Grain dryer consists of a machine. Multiple hot air ducts Multiple air ducts Several grain stack troughs, all of which were built in the lower half of the machine using a net. A conveying device that may transport exact quantities of the grain from the grain stack trough. The grain enters the inside of the material collecting trough in a stand on the bottom of the machine and transports the grain to the top of the machine and allows the grain to fall evenly. Hot air generator This consists of an exhaust fan and an attached hot air generator. Respectively, with the intake and hot air ducts arranged inside the machine and the controls, which are located on the outer part of the machine and may control the operation of the Hot air generating and conveying devices thereof. And which may control measurements and Movement of the relevant automatic control mechanism The main feature of the dryer is Mechanism for swinging the direction of the air provided in the passage. The output of the hot air generator consists mainly of a connecting rod and a drive mechanism. And where the air guide plate Several discs were arranged on the connecting rod. And the extension rod and air guide plate arranged on the connecting rod 331 move back and forth Together by the drive mechanism to heat the hot air blown by the hot air generator can be Uniformly has passed the above mentioned structures and has achieved the purpose of uniform drying. 2. Grain dryer according to claim 1, where the mesh sheet provided in each hot air duct. The intake ducts and grain stack rails inside the machine are constructed into a multi-arc profile. 3. Grain dryer according to claim 1, where the conveying device mainly consists of a feeder, a screw drive mechanism for conveying the grain above. Spiral stalks for lower grain conveying and multi-grained material conveying tooth And where the belt is arranged on the outside of the machine And the upper grain conveying screw is arranged at the top of the machine, and its outer end may receive the grain conveyed by the belt and transfer the grain to the center of the body. Machinery and let the grain fall regularly. And besides that, the fangs transport the material in the section The bottom of the grain trough and is driven by a mechanical drive for continuous transport Grains Inside the trough, stack the grain into the inside of the collector trough arranged in the lower stand of the lower section. Of the machine And a spiral stem for transporting the grain to the bottom may transport the fallen grain. Down inside of the collecting rail to the bottom of the belt mentioned above. Which may re-transport the grain to The upper part of the machine and the grain feeder to the upper grain conveying screw, which transports another grain into the center of the machine 1 and allows the grain to fall smoothly. Regularly to create a flow of recirculation conveyor 4. Grain dryer according to claim 3, where the flang conveys the material mainly consists of the core Conveying materials and multiple sheets And several fixed discs are arranged on the material conveying axis. At the right distance And several concave grooves arranged in a ring shape are arranged on the outer edge of each Plates that are fixed at a reasonable distance. And besides that, several grooves are arranged in the discs Move the material at a position corresponding to each sheet attached to it at the material conveying axis. And grooves on the sheet The material conveying may be coordinated with the indentations provided at each sheet attached to the material shaft. 5. Grain dryer according to claim 3, where the conveying flanges are arranged on the left and Right side of the bottom of each grain stack. And each track is driven together by a chain Or other characteristics And where the spindle of the material handling flang near one side of the hot air tube is connected to Smaller chain wheel While the spindle of the material handling flang near one side of the duct is connected. With larger chain wheels And when the drive mechanism drives the chain wheel to turn And each tooth conveying material near the side One of the hot air ducts is driven to rotate simultaneously at a higher speed. While each tooth conveys the material Located near one side of the duct, the air was driven to rotate simultaneously at lower speed. Therefore, the grain that Located near one side of the air intake pipe, it may be longer to achieve the same drying effect by extending the drying time. 6. Grain dryer in accordance with claim 1, where the air velocity device is located Air or air inlet in the grain dryer of this invention In addition, the inspection equipment Measure air velocity, mainly Fan gauges provided at each airway and air inlet. And because the hot air passing through the fan gauge will cause it to spin. Therefore, the signal value may Was generated from the frequency of rotation to achieve air velocity measurement. And judging the situation Blockage of the mesh disc
