  As shown in FIGS. 13 to 16, the chicken cage lifter 1 includes a chicken cage loading frame 6 including a lower frame 3, a support 4 forming a side frame, and an upper frame 5, a hydraulic cylinder 10, a cylinder rod 12, An elevator mechanism 17 including a cylinder block 14, a sprocket 15, a chain 49, and an elevator 16 is provided. In the figure, 7 is an outer pillar, and 9 is an inner pillar.

  The lifting platform 16 is equipped with a lifting plate 50, and as shown in FIG. 16, can move up and down from the lowermost position (dashed-dotted line position) of the lower frame 3 of the chicken cage loading frame 6 to the truck bed position (solid line position). The chicken cages 41 stacked in three stages are lifted along the chicken cage stacking frame 6.

  Further, a chicken cage stopper 39 rotatable from a horizontal position to an upright position is fixed to the side frame 4 above the upper frame 5 of the chicken cage loading frame 6, and has a flange 40 at a central portion indicated by a broken line in FIG. When the chicken cage 41 composed of a rectangular parallelepiped container is raised, the chicken cage stopper 39 comes into contact with the flange 40 of the chicken cage 41 and is rotated from the horizontal position to the standing position. Returning to the horizontal position, the flange 40 rests on the chicken cage stopper 39.

  When the chicken cage lifter 1 is transported by the transport truck to the chicken cage loading place, the chicken cage lifter 1 is transferred onto the power gate 22 and the chicken cage lifter 1 is transferred to the truck bed 18 via the transfer plate 32. Get in touch.

  During this ascent, the chicken cage stopper 39 projecting into the chicken cage raising passage inside the side frame 4 comes into contact with the flange 40 of the chicken cage 41 and is rotated upward, so that the chicken cage 41 is obstructed by the chicken cage stopper 39. The chicken cage 41 is held by the elevating plate 50 when the elevating plate 50 is in the solid line position in FIG. 16. When the elevating plate 50 is lowered, the chicken cage 41 immediately descends together with the elevating plate 50. The flange 40 of the chicken cage 41 engages with the chicken cage stopper 39 and is held at that position, and only the elevating plate 50 descends to the lowermost position (the dashed line position in FIG. 16).

  Thus, the preparation for the next loading of the chicken cage 41 is completed, and the cycle of loading, raising, holding, and lowering the chicken cage 41 is repeated three times in the same manner as described above, and nine chicken cages 41 are sequentially stacked, and FIG. The chicken cage 41 of the nine-stage stack is transferred to the truck bed 18 via the transfer plate 32 while holding the lifting plate 50 in the state shown by the solid line.

  On the truck bed 18, nine rows of chicken cages 41 are stacked in three rows and 17 rows from the driver's seat side to the power gate 22 side.

  When the transfer of the chicken cage 41 to the transport truck is completed, the power gate 22 is raised to the height of the truck bed 18, and the chicken cage lifter 1 is pushed into the truck using the wheels 2 of the chicken cage lifter 1.

  In the chicken cage lifter of Patent Document 1, the transfer plate 32 is provided on the left side surface of the chicken cage loading frame 6, and the chicken cage 41 of nine-stage stacking is transferred to the truck bed 18 via the transfer plate 32, but the chicken cage is 41 is transferred in a direction changed by about 90 ° from the direction of loading the chicken cage lifter 1. Such a change in direction results in poor working efficiency.

  The chicken cage stopper 39 holds the flange 40 of the chicken cage 41, and can be used only when such a chicken cage with a flange is used.

  An object of the present invention is to solve the disadvantages of the prior art, and the chicken cage can be discharged from the loading side to the opposite side and transferred to the truck bed, so that it is easy to use, and the flange width for raising and holding is not sufficient. An object of the present invention is to provide a chicken cage lifter that can stably hold a chicken cage having a shape.

In order to achieve the above object, according to the present invention, an elevator is provided so as to be able to ascend and descend in a chicken cage loading frame having wheels, and the chicken cages loaded from the chicken cage loading frame opening are sequentially stepped from below.

  As shown in FIG. 15, a chain fixing frame is fixed to the upper part of the hydraulic cylinder 10, one end of a pair of chains 49 is fixed to the chain fixing frame, and the other end is fixed to the lift 16. Since the chain 49 is hung over the pair of left and right sprockets 15 supported by the cylinder block 14, the cylinder rod 12 rotates while engaging with the pair of sprockets 15, and the elevator 16 moves up and down via the pair of chains 49. .

  As described above, since the cylinder block 14 is fixed to the inner frame 4 and the chain 49 meshing with the sprocket 15 is fixed to the lift 16, the inner frame 9 is raised and lowered by the expansion and contraction of the cylinder rod 12 and the chain 49 rotates. Therefore, the lift 16 is moved by the inner frame 9 and the chain 49 twice the moving distance of the cylinder rod 12.

  The lift 16 can be moved up and down from the lowermost position (dashed-dotted line position) of the lower frame 3 of the chicken cage loading frame 6 to the truck loading position (solid line position), and the stacked chicken cages 41 are placed in the chicken cage loading frame 6. It is designed to be lifted along.

  The chicken cage loading frame 6 includes a rectangular lower frame 3, a column 4 that forms a side frame standing upright from four corners of the lower frame 3, and an upper frame 5 that connects the columns 4 to each other at a truck bed height position. The front side shown in FIG. 4 was the loading port 11 for the chicken cage, and the upper part on the opposite rear side was the discharge port 23 as shown in FIG.

  As shown in FIG. 5, the rear surface of the chicken cage loading frame 6 is made of a rectangular plate, and is rotatable upward around a shaft 32a provided between the columns 4 below the upper frame 5. The crossover plate 32 is provided so as to match the lower end of the discharge port 23.

  In the figure, reference numeral 25 denotes a bar-shaped lock pin provided on the support column 4, and fixes the crossing plate 32 when not in use with a vertical body.
