DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening of a drying cabinet by an endothermic coating integrally formed with the drying cabinet, without using an expensive building structure requiring a special foundation for a drying cabinet for accommodating the drying cabinet. The present invention relates to a solar-heat-based grain drying apparatus capable of efficiently drying a large-capacity grain with a dry hot air obtained by a permeation and absorption of solar heat by a simple configuration covering the side.

[0002]

2. Description of the Related Art Conventionally, in a drying workplace of an expensive building structure requiring a special foundation, an upper surface opening is formed so that an upper portion is formed into a drying room with a horizontal ventilation plate as a boundary, and a lower portion becomes a heat absorbing room. -Shaped drying cabinet is installed, and the stirring and transferring action of the stirring and transferring machine that reciprocates while rotating the large-volume grain put into the drying chamber along the longitudinal direction, and the drying hot air obtained by the permeation and absorption of solar heat. A grain dryer that can be efficiently and uniformly dried by a suction circulation action and then discharged by a discharge hopper is known, for example, described in JP-A-4-93586 before the present application.

[0003]

By the way, in this conventional seed drying apparatus, a drying work place for absorbing the transmitted solar heat to obtain a dry hot air requires a special foundation, a large amount of building materials, and a lot of work. Due to the building structure requiring personnel, it is inevitably expensive, and as a result, it is not possible to perform the efficient drying operation by reducing the facility cost of the drying device.

In addition, in the conventional drying apparatus, the dried grains discharged from the unloading hopper are supplied to an unloading conveyor in a pit excavated and formed underground and are then unloaded to an appropriate place. However, there is a problem that the installation requires a lot of cost, and the repair work also takes a lot of time.

According to the present invention, a simple and inexpensive structure that covers the open side of the drying cabinet with a heat absorbing covering integrally formed with the drying cabinet efficiently absorbs the solar heat, thereby saving fuel consumption of large-capacity grains while reducing fuel consumption. Forgiveness that can dry well,
It is an object of the present invention to provide a more inexpensive solar-heat-based grain drying apparatus in which both a discharge hopper and a carry-out conveyor are of a ground type.

[0006]

Means for Solving the Problems In order to achieve the above-mentioned object, in the grain drying apparatus utilizing solar heat according to the present invention, the structure of the first aspect is characterized in that an upper part is in a drying chamber with a horizontal ventilation plate as a boundary, and a lower part is in a lower part. tunnel but covering the open top shaped dry筺were partitioned and formed so that a suction chamber, the open side of the drying筺

[0007] In the second aspect of the present invention, the discharge hopper and the carry-out conveyor adjacent to the discharge side of the drying cabinet are provided at a position higher than the floor on which the drying cabinet is installed .

[0008]

[Function] Solar heat is radiated inside through the heat absorbing coating,
When the temperature inside the heat absorbing coating is raised to an appropriate temperature by the heat absorbing action of the solar heat, the heated air is transferred while being stirred and mixed sequentially from the supply side to the exhaust side in the drying chamber provided in the drying cabinet. The cereal is sucked and circulated to the cereal, and the cereal is efficiently dried by the dry hot air obtained by the endothermic effect of solar heat.

[0009] When the dried cereal dried to a predetermined moisture is obtained, the dried cereal is discharged into a discharge hopper, then discharged from a discharge hopper by a discharge conveyor, and is discharged to an appropriate place. Good.
