Each of the divided unit bodies is provided at an edge portion that is plane-symmetric with respect to the mating surface, and an inner surface portion that is positioned above the space in a state of being joined to each other, and the flow path portion and the space And a mounting portion to which a partition member for partitioning is attached .

[Operation and effect of invention according to Solution 1]
According to the configuration of the present invention shown in the above solution 1, the discharge port constituting member that is hollow in order to form a grain passage in the combined state is not constituted by a single member, Since it is configured by combining the mating surfaces provided in the pair of divided unit bodies, the divided unit body of the discharge port constituting member is not a complicated shape that is difficult to process such as having a hollow inside, but is made of a plate material A relatively simple shape that can be formed by bending can be obtained. Accordingly, the press-molding die can be a small and relatively simple die, and therefore the number of processing steps can be reduced.

Since each of the divided unit bodies is provided with edge portions that are plane-symmetric with respect to the mating surface, when the edge portions are abutted with each other, the respective mating surfaces are on the same plane. It can be in a positioned state.
In other words, in this state where the respective mating surfaces of the respective divided unit bodies are located on the same plane, the edge portions provided in the respective divided unit bodies can be brought into a butted state. In a state in which the divided unit bodies are connected in series, the divided unit bodies can be positioned on both sides of the edge portion.

The manufacturing method of the discharge port constituent member of the grain carry-out device according to the present invention, which has been taken in order to achieve the above object, has structural features and effects in the following points.
[Solution 2]
The present invention is a method for producing a discharge port constituting member of a grain carrying-out device constituted by joining a pair of divided unit bodies at a predetermined mating surface,
The intermediate product having the pair of divided unit bodies, the mating surface portion of the pair of divided unit bodies positioned on one plane and the pair of divided unit bodies Is manufactured by molding one member so that it can be distributed to separate locations on both sides across the planned cutting location,
A pair of divided unit bodies are constructed by cutting the intermediate product at the planned cutting portion that becomes the boundary of the portion that becomes each divided unit body,
A discharge port constituting member is configured by joining the cut divided unit bodies at the mating surfaces.

[Operation and effect of invention according to Solution 2]
According to the configuration of the present invention shown in the above solution 2, the portions to be a pair of divided unit bodies are separated from each other in a state where the respective mating surface portions are located on one plane and one member is separated. An intermediate product is manufactured by sorting and molding on both sides sandwiching the planned cutting location, and the intermediate product is cut at the planned cutting location that becomes the boundary of each divided unit body. A divided unit body can be formed.
Therefore, the mold for molding the intermediate product may be a single mold, and a pair of divided unit bodies can be manufactured at once using a single mold.
As a result, it is possible to reduce the number of parts and the number of processing steps as compared with the case where a separate mold is prepared for each divided unit body and manufactured in a separate process.

  Further, the mold used for constituting each divided unit body is a single one, and the divided intermediate product is divided into two parts to constitute individual divided unit bodies. However, in that case, the mating surface is formed at the edge of the part different from the part to be divided into two parts, and since these mating surfaces are formed by a single mold, the flatness is ensured accurately. The subsequent assembly work can be performed with high accuracy.

[Solution 3]
Another technical means of the present invention taken in order to solve the above problem is that the mating surface of the divided unit bodies in the box-shaped discharge port constituting member having the discharge port opened downward is discharged along the vertical direction. The planned cut portion of the intermediate product is formed in a direction intersecting with the discharge port forming portion so as to be formed at a portion where the outlet is divided.

Are formed in a direction intersecting with the discharge port forming portion.
In other words, the discharge port component is generally provided with a discharge port that opens downward and is formed in a box shape that is long vertically, so that the mating surface of the divided unit body is the length of the cylinder for transferring the grain. If it is formed in a direction along the direction and at a location where the discharge port is divided along the up-down direction, it becomes easy to form each divided unit body.
That is, for example, when the mating surface is formed along a horizontal plane parallel to the discharge port, the divided unit body below the mating surface is cylindrical, and the upper divided unit body is closed on the ceiling side. Although it is difficult to form by simple pressing or the like, if a mating surface is configured as in the present invention, a half box-shaped split unit body is configured on both the left and right sides of the mating surface. Therefore, there is an advantage that the narrowed portion of the sheet metal at the time of molding does not become so deep, and it is easy to perform the molding process easily by pressing.

[Solution 4]
The other technical means of the present invention taken to solve the above-described problem is that the mating surfaces of the respective divided unit bodies are provided with fitting portions that overlap in the perspective direction of the mating surfaces, where the intermediate product is to be cut. It is characterized by being distributed on both sides.

[Operations and effects of invention according to Solution 4]
According to the configuration of the present invention shown in the solving means 4 above, the mating surfaces of the respective divided unit bodies can be formed with fitting portions that overlap in the perspective direction of the mating surfaces. The assembling work between the divided unit bodies can be easily performed by the fitting operation between the divided unit bodies.
In addition, the structure provided with the fitting portion has an advantage that the connection strength at the mating surface portion can be improved and the adhesion degree of the connection portion can be increased as compared with the simple butting structure.
