However, this means prepares a jack having a structure conforming to the shape of the box frame a ... In order to jack up the box frame a ... There is a problem that there are restrictions that must be done.

The present invention has been made in order to solve the above-mentioned problems that have occurred in the conventional means, and includes a box frame a ... In which a dryer main body A is vertically divided into a plurality of parts.
When assembling the dryer main body A by stacking the dryer main body A by raising and lowering using a jack, the jack to be used has a shape of a box frame a ...
An object of the present invention is to provide a new means that enables appropriate correspondence even if there is a difference in size, and that allows the box frames a ... to be safely jacked up.

[0009]

As a means for achieving the above-mentioned object, the present invention incorporates a dryer main body having a box-shaped or hollow tower-shaped structure having a high machine height into a discharge conveyor or the like. By stacking and connecting the box frame that will be the lower box and the box frame that will be the middle box that incorporates the drying section such as the hot air duct and the multiple box frames that will be the upper box that will form the grain storage tank In the dryer main body of the grain dryer to be assembled, screw jack type jacks are mounted in parallel in at least two rows on each outer surface of the box plate facing left and right or front and back of the box frame forming the lower box, By the synchronized operation of these jacks, a plurality of upper and lower box frames and a middle box box are sequentially jacked up and stacked, and they are connected and connected to assemble the dryer main body. Providing an assembly method for the dryer main body In addition, the dryer main body having a high box height or a hollow tower shape becomes a lower box that incorporates a discharge conveyor and a middle box that incorporates a drying section such as a hot air guide passage. It is divided into a box frame and a plurality of box frames that form an upper box that forms a storage tank for grains, and screw jack type jacks are provided on the outer surfaces of the box plates that face left and right or front and back of the box frame that forms the lower box. At least two in parallel and suspended in a detachable manner, and a box frame serving as a middle box and a plurality of box frames serving as upper boxes are
Engagement machine for releasably engaging the pedestal of the jack with a portion of the box frame constituting the lower box that removably suspends the jack of the box frame and a portion near the lower edge of the box plate that corresponds vertically. The present invention proposes a device for assembling a dryer main body in a grain dryer in which frames are respectively installed.

[0010]

According to the means of the present invention, the jack w used for jacking up the box frame a ... Forming the dryer main body A in the vertically divided form is the lowermost box frame constituting the lower box 1. By suspending and supporting the outer wall surface of a in a detachable manner, the lowermost box frame a serves as a support stand for the jack w. Therefore, the size and shape of the box frame a to be jacked up Even if there is a difference in, it will be possible to correspond appropriately. Also, even when the jack swings when jacking up and stacking the box frame a serving as the middle box 2 and the box frame a serving as the upper box on the lowermost box frame a serving as the lower box 1. In this way, it is possible to effectively prevent the positional deviation between the box frame a to be moved up and down and the lowermost box frame a.
