Among the grain dryers in which the drying section is installed in parallel with the exhaust path that guides the wind, the hot air path of the drying section installed inside the machine is located outside the machine and The present invention relates to improvements in an outside hot air / inside exhaust type grain dryer in which the air passage is located in the center of the airframe.

[0002]

[Prior art]

 As shown in FIG. 1, the grain drier of the above-described form usually has grains to be dried inside the upper box 1a forming the upper half side of the machine body 1 formed in a vertically high box shape. Inside the middle box 1b, which is provided with a storage part w for accommodating and forms the lower half side thereof, hot air for supplying grain downflow passages 20 and grains flowing down through the grain downflow passages 20. The drying section y is provided in which the hot air passage 21 for guiding the air and the exhaust air passage 22 for guiding the exhaust air blown out from the hot air passage 21 and blowing out the grain layer in the grain downward passage 20 are parallel to each other. In the lower box 1c forming the bottom of the airframe 1, the rotary shutter 3 for controlling the amount of the grains flowing through the grain lowering passage 20 and the grains exposed to the hot air flowing through the grain lowering passage 20 are provided. A lower conveyer 4 to be carried out is installed on the front side of the machine body 1, and the end side in the carrying direction of the lower conveyor 4 is erected on the front side of the machine body 1. The discharge cylinder part 51 provided in the upper part of the elevator 5 is connected and communicated with the bottom part of the fried tower 50 of the descending machine 5, and is communicated with the ceiling part of the storage part w in the machine body 1 through the upper conveyor 52. 1 is equipped with a hot air generator for generating hot air to be sent to the hot air passage 21 of the drying section y, and on the rear surface of the machine body 1, exhausted air is sucked from the exhaust air passage 22 and eliminated. It is configured by mounting the exhaust fan 6 that operates.

In the drying section y installed inside the middle box 1b of the machine body 1, the hot air passage 21 arranged on one of the left and right sides of the grain lowering path 20 has the outer wall board a of the middle box 1b. The exhaust passage 22 located on the inner side and disposed on the other side of the grain lowering passage 20 is provided so as to be located on the center side in the machine body 1, whereby the outer hot air / inner exhaust It is configured in a wind-type grain dryer A.

[0004]

[Problems to be solved by the device]

 In the grain dryer A having the above-described configuration, the hot air passages 21 that guide the hot air, which is the dry wind, to the grains flowing through the grain downflow passage 20 of the drying section y are provided on the left and right outside of the machine body 1. By being positioned, the inner box serves as a partition wall on the outer surface side of the hot air passage 21 due to the heat of the hot air generated by the hot air generating device mounted on the front side of the machine body 1 and sent to the hot air passage 21. There is a problem that the outer wall plate a of 1b is heated to a high temperature and causes a burn injury accident when an operator touches a body such as a hand during a drying operation.

Further, a part of the outer wall plate a of the inner box 1b for accommodating the drying section y of the machine body 1 is formed into an openable / closable door for the machine body 1 and is opened by its opening rotation. From the incoming port z, the grains to be dried are poured toward the lower conveyor 4 at the bottom 1c of the machine body 1 via the hot air passage 21 which is opened to the outside by the inlet z, and from the conveyor 4. Since it is stretched by the elevator 5 into the storage part w inside the upper half 1a of the machine body 1, when operating the open / close door to open this stretch port z, consider that it is heated. There is an annoying problem to do.

The present invention has been made in order to solve the above-mentioned problems occurring in the grain dryer configured in the form of exhaust air with the outside hot air. Since the outer wall plates a ... Are partition walls that surround the outer periphery of the hot air passage 21 of the drying section y, when they are heated by receiving the heat of the hot air sent to the hot air passage 21 during the drying operation, A worker's body comes into contact with the outer surface of the outer wall plate a ... causing an accident such as a burn, or the handling of the opening / closing door of the overhang z formed by a part of the outer wall plate a. And to provide new means to effectively reinforce the strength of the fuselage 1.

[Means for Solving the Problems]

 In the present invention, as means for achieving the above-mentioned object, at least the left and right of the four machine walls of the middle box 1b portion of the box-shaped machine body 1 that stores the drying part y are provided. A shallow flat box-shaped heat insulating plate b is integrally attached to the outer surface of the side outer wall plate a in the form of a double wall, and a space formed between the heat insulating plate b and the outer wall plate a. The present invention proposes an outside hot air / inside exhaust type grain dryer characterized in that c is communicated with the outside air through a ventilation port d ... Opened in the peripheral wall portion of the flat box-shaped heat insulating plate b. is there .

The device of the present invention having the above-described structure is a heat insulating device formed on the outer surface side of the outer wall plate a of the middle box 1b of the machine body 1 accommodating the drying section y by forming a shallow flat box shape on the outer surface thereof. There is an empty space c formed by the inner cavity of the plate b, and the empty space c is communicated with the outside air by a large number of vent holes d ... Formed in the peripheral wall portion of the flat box-shaped heat insulating plate b. Since the air in the empty chamber c effectively acts as a heat insulating layer, the outer surface side of the outer wall plate a is safely held so as not to cause a burn injury accident even if the worker's body comes into contact with it. Further, since the outer wall plates a are effectively reinforced by the flat box-shaped heat insulating plate b attached to the outer surface thereof, the airframe 1 is effectively reinforced while the handling is easy.
