Abstract

PURPOSE:To enable efficient transfer of grain charged directly onto the charge side of a drying case by a truck or the like to a position determined beforehand, by a transferring operation of an agitating rotor. CONSTITUTION:A position A or B in a drying case 4 to which grain charged directly onto the charge side (a) of a drying chamber 4 by a truck 5 or the like is to be transferred is determined beforehand. Then, an agitating rotor 15 is thrust downward obliquely into the charged grain and the charged grain is transferred thereby sequentially toward the discharge side (b) from the charge side (a) and thus transferred to the position A or B determined beforehand, by the agitating rotor 15.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method in which a stake grain directly squeezed by a carrier or the like to the squeeze side of a dry casing is swiftly and accurately applied to a predetermined position under a light load only by a reciprocating transfer operation of a stirring rotor. The present invention relates to a method for loading grain in a solar heat drying facility that can be transferred to.

2. Description of the Related Art Conventionally, a predetermined amount of grain is contained in a horizontally elongated dry casing, and the grain has a reciprocating stirring transfer action of a stirring rotor and a circulation action of dry hot air obtained by a solar heat permeation and absorption action. In a drying facility using solar heat that can be dried to a specified water content, a work of loading a predetermined amount of grain into the drying enclosure is performed at the start of drying, and this is one of the means for loading the grain. Directly below the flow control tank arranged on the stake-in side, a carrier truck capable of reciprocating on the drying housing is mounted, and after the grain put into the flow control tank is supplied to the carrier truck via the cargo receiving device, The grain leveling and feeding device in the agitation draft dryer, which is configured to drop and feed to the predetermined position of the drying housing by the reciprocating operation of the carrier, is known and disclosed in, for example, JP-A-4-93586 before the present application. .

By the way, in the conventional grain staking method of this kind, a flow control tank and a carriage are required in addition to the cargo receiving equipment provided with a large number of elevators and cargo hoppers. However, there is a problem in that the entire apparatus becomes large in size, its configuration becomes extremely complicated, and many failures occur, and the facility house is inevitably large and the facility cost is high and expensive.

According to the present invention, even without using any cargo receiving equipment, a flow control tank, a carrier, etc., the grain directly loaded on the loading side of the drying cabinet by a carrier etc. is simply reciprocated by the stirring rotor. Whether it is possible to quickly and accurately transfer it to a predetermined position by using the above-mentioned method, it is possible to reduce the consumption power, simplify the facility structure and reduce the facility cost easily. It is intended to provide a way.

[0005]

In order to achieve the above object, in the grain stake method in the solar heat utilizing drying facility of the present invention, the method of the first item is applied to the stake side of the drying chamber by a carrier or the like. After determining in advance to which position in the dry box the directly loaded grain should be transferred, the stirring rotor is thrust diagonally downward to the loaded grain and the loaded grain is transferred from the loading side to the discharge side. The grain is transferred sequentially to the grain and is then transferred to a predetermined position by the stirring rotor.

[0006]

[Operation] Grains carried by a truck such as a dump truck are carried into the stake-in side of the drying cabinet. Then, when a predetermined amount of grain has been loaded on the loading side, after first deciding where to move the grain to, for example, the A position or the B position in the drying housing, the discharge side origin position (at this time, (The rotor is raised to the highest position) While running the stirring rotor that was stopped in the direction of the arrow while running to the stake side,
When the agitating rotor approaches the stake grain, the rotor is gradually lowered so that the sloping grain is inclined downward.

By virtue of this, when the stirring rotor rushes into the piled-up grains under the obliquely downward state, the accumulated grains are gradually scraped and transferred to the discharge side, so that less power is required. However, the grain can be quickly and accurately transferred to the position A by only the stirring rotor.

When it is desired to transfer the stake grain to a position B which is farther from the position A due to the amount of received grain,
The stirring rotor that has traveled to the stake-side end position is raised to the maximum ascent height in the rotating state or the non-rotating state, and then the stirring rotor is discharged to a position past the grain that was previously transferred at point A. After moving to the side, the stirring rotor is gradually lowered again to run toward the stake-in side, so that the grain at the point A is slanted downward, and the grain at the point A is moved to the point B by the stirring rotor. At the same time as transferring the grain to the position, the grain carried into the stake-in side is transferred to the point A position.

Therefore, by repeating the above-mentioned operation, it is possible to transfer all of the loaded grains directly loaded to the loading side of the drying casing into the drying casing at the A point or B point position which was initially determined. it can.

[0011]

Since the present invention has the method as described above, it has the following effects. Since the grain to be dried can be directly carried in to the loading side of the drying box using a truck such as a dump truck, compared to the conventional loading method using a cargo receiving device, a flow control tank, and a carrier truck, Its configuration is extremely simple, and it can be loaded quickly and efficiently without failure, and the grain is determined in advance only by the movement of the stirring rotor running from the discharge side to the stake side. Perhaps it can be accurately transferred to the dry casing at the position, but when the stake grain was transferred, it was transferred to the discharge side while thrusting the stirring rotor diagonally downward to the stake grain, so under a low load condition. It is possible to efficiently transfer the stake grain.
