 In order to uniformly dry the grains contained in the drying casing under the static condition by the stirring and mixing action and the endothermic action of solar heat, the present invention is applied when the transported grains are supplied to the flow control tank and When using the solar heat to supply the transport vehicle from the flow control tank, it is possible to quickly suck in and remove a large amount of dust that has tended to fly up to the surroundings, allowing efficient grain supply work under hygienic environmental conditions. -Type grain dryer

[0002]

[Prior art]

 Conventionally, a horizontal ventilator is laid in a horizontally long drying cabinet with an open upper surface, and a drying chamber is formed in the upper part and a suction chamber is defined in the lower part with the horizontal ventilating board as a boundary. In addition to being equipped with a carrier cart that can travel back and forth along with a stirring and mixing transfer machine, a flow control tank for supplying grain to the carrier cart is installed on the loading side of the drying cabinet, and the inside of the drying cabinet is left stationary. An agitated draft dryer capable of uniformly drying the grains stored in the container by the stirring and mixing action and the endothermic action of solar heat is described in Japanese Patent Application Laid-Open No. 4-93586 prior to the present application and is known.

[0003]

[Problems to be solved by the device]

 By the way, in this type of conventional agitation draft dryer, there was no dust extractor installed on the loading side of the drying cabinet, so when loading grain into the flow control tank or from the flow control tank to the carrier truck. When throwing in, the dust that was mixed in a large amount in the grain floats up to the surroundings, deteriorating the work hygiene environment and lowering work efficiency, and the dust that rises is the wall of the solar heat absorption chamber. However, there was a problem that it adhered to the surface of the solar cell and reduced the heat absorption efficiency of solar heat transmission, and the drying work efficiency was reduced.

The present invention has been made in view of the above problems of the prior art. The purpose of the present invention is to load the conveyed grain into the flow control tank and to change the flow rate. A large amount of dust that was trying to fly up to the surroundings when it was thrown into the carrier from the adjustment tank was forcibly sucked and discharged to the outside through the upper and lower suction and dust chambers, so that the grain was thrown in under hygienic environmental conditions. Whether the work can be accomplished easily or not, the aim is to increase the heat absorption effect of solar heat to provide a more efficient dust removal device in a solar heat type grain dryer.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the dust removing device in the solar heat type grain dryer of the present invention has a horizontal drying cabinet with an open upper surface, and a drying chamber at the top and a drying chamber at the bottom with a horizontal ventilator as a boundary. The chamber is divided into compartments, and a transport carriage that can reciprocate in the longitudinal direction and an agitating / mixing transfer machine are mounted on the drying cabinet, and a flow control tank for supplying grains to the transport cart is installed on the loading side of the drying cabinet. The upper and lower suction dust chambers, one side of which is connected to the suction dust collector, are installed at the upper facing position of the flow control tank and the lower facing position of the flow control tank. It will be.

[0006]

[Action]

 After installing the flow control tank with the shutter open on the loading side of the drying cabinet and the transport carriage with the shutter closed underneath it, you can load the transported grains one after another into the flow control tank. The grain is supplied to the lower carriage by way of the flow control tank.

By the way, at the same time as the work of sequentially supplying the above-mentioned grain to the carrier vehicle through the flow control tank, the suction / exhaust air blower is operated to move to the upper facing position in the flow controlling tank and the lower facing position in the flow controlling tank, respectively. Place the upper and lower suction and dust chambers in a negative pressure state.

[0008] By the way, when the grain is put into the flow control tank and when it is put into the transport vehicle below the flow control tank, many dusts trying to fly up to the surroundings are located at the opposite positions, respectively. After being forcibly sucked into the upper and lower suction / dust collection chambers, the dust is concentrated to the outside, so that dust does not come up to the surroundings during the grain input work to the flow control tank and the grain input work to the carrier truck. Permitting that it can be operated under environmental conditions, since dust does not adhere to the solar heat transmission / absorption wall, the solar heat transmission rate can be increased and the air temperature in the drying workshop can be raised efficiently.

[0009] When the carrier truck is fully filled with grain, the shutter of the flow control tank is closed, and then the carrier truck is advanced toward the discharge side along the horizontally long drying casing, and at the same time, the shutter of the carrier truck is closed. When opened, the contained grains are put in the drying chamber one after another.

Therefore, by repeating the above-mentioned operation, when a large amount of grain is put into the drying chamber, the stirring / mixing transfer rod is reciprocated along the longitudinal direction of the drying casing to level the grain at the same time. During the transfer with stirring and mixing, the drying air is passed through the drying chamber to the suction chamber and slowly dried to the specified moisture with the warm air obtained by the solar heat that is circulated through the suction chamber.

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. The grain feeding work into the horizontally long drying chamber with the upper surface opened can be performed quickly, accurately, and efficiently at any place by the reciprocating operation of the transport carriage without depending on the transport of the stirring and mixing transporter. It is possible to dry quickly due to the stirring and mixing transfer action of the stirring and mixing transfer device and the suction and circulation action of the warm air obtained by the permeation and absorption of solar heat. Since it has been supplied, it is possible to always supply a fixed amount of grain to the transport carriage and put it into the drying chamber, and one side is sucked and discharged at the upper facing position and the lower facing position in the flow control tank.
