A detachable vertical bar 21 is detachably mounted between the vertical bars 20, and a detachable horizontal bar 23 is detachably mounted between adjacent welding horizontal bars 22 in the welding grid network 25.

  That is, the grid 13 according to the embodiment of the present invention can change the scale based on selective attachment / detachment (or position change) of the attachment / detachment vertical bar 21 and the attachment / detachment horizontal bar 23, for example, as shown in FIG. As shown in FIG. 5, all the removable vertical bars 21 and the horizontal bars 23 are attached to minimize the mesh (soybean specifications), and all the removable vertical bars 21 are removed as shown in FIG. As shown in FIG. 7, the state expanded in the trunk axis direction (buckwheat specification), as shown in FIG. It is possible to select a state in which all the detachable vertical bars 21 and the detachable horizontal bars 23 are removed and the scales are enlarged in the cylinder axis direction and the cylinder circumferential direction.

  Next, the shapes and attachment structures of the welding vertical bar 20, the welding horizontal bar 22, the detachable horizontal bar 23, and the detachable vertical bar 21 will be sequentially described with reference to FIGS.

  As described above, the welding vertical beam 20 is an arc-shaped plate member extending in the circumferential direction of the barrel, and the welding horizontal bar 22 and the detachable horizontal bar 23 are attached to the end on the inner peripheral side in a penetrating manner. A plurality of round holes 20a are formed at a predetermined interval in the circumferential direction of the cylinder. The vertical welding bars 20 are arranged in parallel at a predetermined interval in the axial direction of the barrel, and the upper and lower ends thereof are welded to the frame body 24. In addition, a plurality of through-holes 20b for bolting a retaining plate 26, which will be described later, are formed on the welding vertical beam 20 positioned at both ends in the barrel axial direction at predetermined intervals in the barrel circumferential direction. Yes.

  As described above, the welding horizontal bar 22 is a round bar member extending in the axial direction of the barrel, and is attached to the round hole 20a of the welding vertical beam 20 in a penetrating manner and welded to the welding vertical beam 20. In the lattice network 13 of the present embodiment, the round holes 20a of the welding vertical rails 20 are formed at substantially equal intervals, and the welding horizontal bars 22 and the detachable horizontal bars 23 are alternately attached to these round holes 20a. . That is, one detachable horizontal bar 23 is attached between adjacent welded horizontal bars 22, but if the same number of detachable horizontal bars 23 are attached between adjacent welded horizontal bars 22, adjacent welded horizontal bars Two or more detachable horizontal bars 23 may be attached between the bars 22.

  The detachable horizontal bar 23 is a round bar member having the same shape as the welded horizontal bar 22, and is attached to the round hole 20 a of the welding vertical bar 20 in a penetrating manner so as to be parallel to the welded horizontal bar 22. Then, the attached detachable horizontal bar 23 is retained by the retaining plate 26 attached from the outer side to the welding vertical beam 20 located at both ends in the barrel axial direction, and the retaining plate 26 is removed. The detachable horizontal bar 23 can be removed. The retaining plate 26 is formed at a plurality of positions corresponding to the plurality of notches 26 a that avoid interference with the end portion (or weld bead) of the welding horizontal bar 22 and the through hole 20 b of the welding vertical rail 20. It has a through hole 26b, and is fixed to the welded vertical beam 20 at both ends by tightening a bolt 27 passing through the through holes 26b and 20b and a nut 28 screwed into the bolt 27.

  The detachable vertical beam 21 is an arc-shaped plate member extending along the circumferential direction of the barrel like the welded vertical beam 20, and a round hole for attaching the detachable horizontal bar 23 in a penetrating manner at the inner peripheral end thereof. 21a and a plurality of notches 21b for avoiding interference with the welding horizontal bar 22 are alternately formed at predetermined intervals in the circumferential direction of the cylinder. The detachable vertical bars 21 are arranged in parallel between the adjacent welded vertical bars 20, and attachment parts 21 c that are bent at both upper and lower ends thereof are attached to the frame body 24 via bolts 29. That is, the through hole 21d of the bolt 29 is formed in the mounting portion 21c of the detachable vertical beam 21, while the screw holes 24a and 24b into which the bolt 29 is screwed are formed at the mounting position of the frame body 24. In addition, although the screw holes 24a and 24b of this embodiment are formed with the welding nut 24c welded to the back side of the frame 24, you may make it form in the frame 24 directly.

  A plurality of attachment positions of the detachable vertical bars 21 in the frame body 24 are provided between the adjacent welded vertical bars 20. Specifically, a scale reduction mounting position (see FIG. 11: using screw holes 24a) for mounting the detachable vertical beam 21 at an intermediate position between adjacent welding vertical beams 20, and a proximity position of the welding vertical beam 20 Is provided with a storage mounting position (see FIG. 12: using the screw hole 24b) for storing the detachable vertical beam 21. If it does in this way, it will become possible to change a scale based on the change of the attachment position of the detachable vertical beam 21, without removing the detachable vertical beam 21. Further, in the state where the detachable horizontal bar 23 is attached, the detachable horizontal bar 23 penetrates the round hole 21a of the detachable vertical bar 21, so that not only the support strength of the detachable horizontal bar 23 is increased, but also the detachable vertical bar 23 is attached. When the mounting position of the crosspiece 21 is changed, there is an advantage that the detachable vertical crosspiece 21 is temporarily held (slide supported) by the detachable horizontal bar 23 and workability is improved. However, the round hole 21a of the detachable vertical beam 21 is not an essential requirement of the present invention, and a notch 21b may be formed instead of the round hole 21a.

  The thickness of the detachable vertical beam 21 is preferably larger than the thickness of the welding vertical beam 20. In this way, the strength of the detachable vertical beam 21 is increased, so that the detachable vertical beam 21 can be smoothly slid along the detachable horizontal bar 23 when changing the mounting position of the removable vertical beam 21. In addition, in the welded vertical beam 20 whose strength is ensured by welding, the plate thickness can be made thinner than that of the removable vertical beam 21, so that the weight of the grid network 13 can be reduced. In addition, there is an advantage that it becomes easy to identify the detachable vertical beam 21 to be attached / detached (position change) due to the difference in the plate thickness.

  It is preferable that the number of the detachable vertical bars 21 is smaller than the number of the welded vertical bars 20. For example, in the grid network 13 of the present embodiment, four detachable vertical bars 21 are provided for the five welded vertical bars 20. In this way, there is no inconvenience that the detachable vertical beam 21 overflows and cannot be stored when the storage mounting position for storing the detachable vertical beam 21 is secured in the vicinity of the welding vertical beam 20.

  Moreover, it is preferable that the welding bead of the welding horizontal bar 22 with respect to the welding vertical bar 20 should be only one side, not both sides of the welding vertical bar 20. In this case, the detachable vertical beam 21 is stored in contact with the adjacent position of the welded vertical beam 20 by not forming a weld bead on both sides of the welded vertical beam 20 on the side where the removable vertical beam 21 is stored. It becomes possible to do.

  In this embodiment, one detachable vertical beam 21 is attached between adjacent welded vertical beams 20, but two or more removable vertical beams 21 may be attached between adjacent welded vertical beams 20. Good.

Since it has a plurality of fixed welding horizontal bars 22 and a plurality of removable horizontal bars 23 that are detachably attached between adjacent welding horizontal bars 22, the scale can be changed by attaching and detaching the removable horizontal bars 23 to produce crops. Can be expanded. Moreover, since the detachable horizontal bar 23 is attached between the adjacent welded horizontal bars 22, when changing the scale, the horizontal bar 23 to be attached and detached and its attachment / detachment position can be easily recognized.

  The grid network 13 of this embodiment includes a welded grid network 25 formed by welding a plurality of vertical bars 20 and 21 and a plurality of horizontal bars 22 and 23, and a welded horizontal bar adjacent to the welded grid network 25. Since a plurality of detachable horizontal bars 23 are detachably mounted between the two, it is possible to attach the detachable horizontal bars 23 as necessary with reference to the welded grid network 25, thereby expanding the adaptability to crops. Besides, when changing the scale, it is possible to easily recognize the horizontal bar 23 to be attached / detached and its attaching / detaching position. Moreover, since the attaching / detaching horizontal bar 23 is attached to and detached from the welded grid net 25 that is firmly framed, it is possible to prevent a problem that the entire grid net 13 is deformed and the attaching / detaching of the attaching / detaching horizontal bar 23 becomes difficult.
