Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to a storage tank in the upper stage, a ventilation drying cylinder in the middle stage, and a take-out tank in the lower stage, which can be stacked three-dimensionally in order to allow grain to be circulated and dried. This grain dryer is capable of drying fractional quantities of grain by accurately drying fractional quantities of grain using the same grain drying t*v.

Inside the dryer body, which is an oblong rectangular cylinder with an elevator attached to one side,
A storage tank is provided in the upper stage, and a ventilation drying cylinder is provided in the middle stage in which a plurality of hot air chambers and a plurality of exhaust chambers are alternately provided along the horizontal direction so that a drying passage is installed vertically between the two chambers.

A three-dimensional waste tank is installed in a three-dimensional manner in the lower stage, and a loading sieve with a drop-free opening is placed horizontally on the top of the dryer main body, and a predetermined amount of grain stored in the storage tank is placed horizontally on the top of the dryer body. A grain dryer in which circulating air is circulated through an elevator to facilitate the circulation drying operation is known as described in Japanese Patent Publication No. 48-36753 prior to the filing of this application.

By the way, conventional grain dryers of this kind were configured to accommodate a predetermined amount of grain and perform circulation drying, so that during harvesting, fractional amounts of grain less than approximately A of the bulk amount could be stored. When this occurs, the ventilation surface is exposed and the heat supply leaks, making it impossible to dry the grain using the same dryer. A small-capacity grain dryer was purchased and used to perform the drying, which had the disadvantage of being uneconomical in terms of cost.

Therefore, in order to solve the above-mentioned drawbacks of the known grain dryer, the present invention changes the arrangement direction of a plurality of hot air chambers and exhaust chambers arranged vertically in a ventilation drying drum, thereby increasing the length of the drying passage. At the same time, at the same time, it is possible to prevent only a fraction of the grains from falling into the storage tank at the starting end of the carry-in width installed horizontally on the top of the dryer body. During fraction drying work, the fractional amount of grain is always dropped from the shaver droplet into the ventilation drying drum on the carry-in side, which is arranged sequentially from the carry-in side. Grain drying that allows fractional drying by filling the aisles and accurately drying fractional quantities of grain without causing loss of hot air and using the same grain dryer that can perform circulation drying operations. It's a stupid thing for the purpose of gaining an opportunity.

In view of the above, in order to achieve the above object, the present invention has a structure in which a storage tank is provided in the upper stage and a storage tank is arranged in the middle part perpendicularly to the horizontal direction in the main body of the dryer in the form of a horizontally long rectangular tube with an elevator attached to the - side. A ventilation drying cylinder is provided with a plurality of hot air chambers and a plurality of exhaust chambers arranged alternately along the direction so that a drying passage is vertically installed between the compartments.
Eleven take-out tanks are arranged three-dimensionally in the lower stage, and a main drop port is located approximately at the center on the top of the dryer body, and a shaver drop port that can be opened and closed to allow fractional grains to fall is provided on the inlet side connected to the elevator. This grain dryer is capable of drying fractions by adjusting the opening and closing of the grains using a damper. In a grain dryer capable of drying, when a predetermined amount of grain is dropped into the storage tank from the main drop port, the grain is circulated and flowed into the dryer main body via the elevator and the attached gutter. A number of short drying passages can be installed vertically in the ventilation drying cylinder in a direction perpendicular to the horizontal direction, which makes circulation drying work more efficient. However, the grains in the fractional cap are dropped from the lower entrance of the narrow passageway to the carry-in side of the ventilation drying cylinder, and are filled in the drying passage installed vertically in the far direction from the carry-in side, and the air loss is reduced by the circulating drying air. As a result, even if it is a grain dryer in which a storage tank, a ventilation drying cylinder, and a take-out tank are stacked three-dimensionally, the operation of simply opening and closing the shaving opening is simple. As a result, it is possible to easily carry out the circulation drying work of predetermined needle grains and the drying work of fractional grains with a single grain dryer.
