Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grain dryer for rice, wheat, etc., and particularly relates to a reinforcing device for a grain tank frame in a grain dryer.

[Conventional technology]

Conventionally, a grain tank consisting of four frames on the front, rear, left, and right sides is mounted on top of a dryer body equipped with a burner, a drying chamber, etc., and an input port at the top of the grain tank and an outlet provided at the bottom of the main body. In a grain dryer in which a grain circulation path is formed by connecting the two frames by a grain lifting machine, in order to prevent each frame body from expanding outward and breaking due to the pressure of the grain, there is a gap between the opposing frames. A reinforcing connecting member (stay) is installed over the bridge (see Utility Model Application Publication No. 57-73596, etc.). On the other hand, it is well known that the frame body is usually provided with a plurality of window holes covered with a transparent material in order to check the state of grain filling and the like.

[Problem that the invention attempts to solve]

By the way, when a window hole is drilled in the frame, the strength of the frame decreases accordingly, so in order to reinforce the window hole, bends (projections) having elasticity for holding down the window hole are provided on both sides in the longitudinal direction. It is known to form a reinforcing member with an opening corresponding to the window hole (see Japanese Utility Model Application No. 57-64622).

However, since the reinforcing member also has an opening (window hole) corresponding to the window hole, the elastic force for pressing down the frame is poor, and when the reinforcing connecting member is simply fixed to this reinforcing member, the reinforcing connecting member and the reinforcing member The stress of the connecting member was concentrated at the connecting part with the frame, and it was not sufficient to reinforce the frame.

In view of this point, the present invention aims to provide a reinforcing device for a grain tank frame in a grain dryer that can be sufficiently reinforced by a reinforcing connecting member even if the frame is provided with a window hole. This will be a major issue.

[Means for solving problems]

In order to solve the above problems, in the reinforcing device for the grain tank frame in a grain dryer of the present invention, a grain tank consisting of front and rear and both side frames is placed on top of the dryer main body equipped with a ventilation drying section, and Of each frame body, the frame body provided with the transparent window for capacity detection has a reinforcing strip formed with an opening corresponding to the window hole and elastic ridges for holding down on both sides in the longitudinal direction. This is a reinforcing device for a grain tank frame in a grain dryer, which includes: (a) Attaching a cross-sectional (gangamae)-shaped pressing plate so as to cover the reinforcing band plate.

(b) This presser plate and the end of the connecting member spanned between the opposing frames are fastened with bolts and nuts.

This technical measure was taken.

[Action and effect]

When using a grain dryer at a rice center or a farmer's workshop, a cross-sectional press plate is attached to cover a reinforcing strip with an opening corresponding to the transparent window, and this press plate and the opposing frame are Bolt the end of the connecting member that spans between the bodies.
By fastening with nuts, the stress of the connecting member that reinforces the frame is dispersed through the protrusions of the holding plate and the reinforcing strip, and the strength of the parts is weakened due to the provision of the window holes. will not be destroyed.

[Example of idea]

A preferred embodiment of the present invention is shown below in Figures 1 to 3.
This will be explained based on the diagram. A ventilation drying section 3 is formed inside the lower frames 1 and 2 equipped with burners etc. to form the main body of the grain dryer, and a grain tank 8 consisting of the upper frames 4 to 7 is placed on this dryer main body. At the same time, an elevator (not shown) is attached to create a circulating grain dryer.

Next, the structure of the upper frames 4 to 7 forming the grain tank 8 will be described in detail. That is, the frame structure of the grain tank 8 has a plurality of window holes 9 for capacity detection in the vertical direction in the central part.
It is composed of a front frame 4, a rear frame 6, both side frames 5, 7, and a lid (not shown), in which bolt holes (bakaholes) are opened on both sides of the front and rear frames 4, 6. 10... and screw holes 12 provided in both side edge portions 11 of both side frame bodies 5, 7 are respectively tightened with bolts 13, and screw holes 15 in upper edge portions 14 of each frame body 4 to 7 are tightened with bolts 13. ...and tighten the bolt holes provided on the edge of the lid with bolts not shown.

Further, a window plate 16 made of a transparent material is provided on the front frame body 4 so as to close the window hole 9. That is,
A reinforcing band plate 20 is provided with openings 17 corresponding to the window holes 9, and has reinforcing ribs 19 having elasticity for pressing on both sides in the longitudinal direction.
is applied so as to press the window plate 16 against the window hole 9, and furthermore, a cross-sectional pressing plate 22 is provided so as to cover the reinforcing band plate 20, and this pressing plate 2
2, the bolt holes 18 provided in the reinforcing band plate 20, the bolt holes 4a provided in the front frame 4, and the bent portions 23 at both ends of the reinforcing connecting member 23.
The bolt holes 23b and 24 are inserted into the bolt holes 23b and 24, respectively, and tightened with nuts 25.

In the reinforcing device for the grain tank frame in the grain dryer constructed in this way, the edges of each of the frames 4 to 7 and the lid are fixed with bolts 13 or the like, and two pairs of opposing frames are connected. 4 and 6 and frames 5 and 7 are bridged by reinforcing connecting members 23 and 26, respectively. That is, both side frames 5 and 7 have hook portions formed at both ends of a pair of reinforcing connecting members 26 and 26,
The frames 5 and 7 are connected by engaging engaging portions (none of which are shown) provided on the inner walls, and the front and rear frames 4 and 6 are connected to the bent portions at both ends of the reinforcing connecting member 23. Insert the bolt 2 from inside the grain tank 8 into the bolt hole 23b opened in the
4 through the frames 4 and 6, the bolt holes 18 of the reinforcing band 20, and the bolt holes 21 of the holding plate 22, and then tightened with nuts 25.

As a result, the stress of the reinforcing connecting member 23 when the grain is loaded into the grain tank 8 is dispersed by the holding plate 22 and the protrusions 19, 19, and the grain is circulated without destroying the vicinity of the window hole 9. Can be dried.
