  Furthermore, since the traveling scraper 20 includes a V-shaped scraper 21 and a guide plate 22 that rotates around the apex of the V-shaped scraper 21, the guide plate 22 is rotated and set in an arbitrary direction. With the one traveling scraper 20, the improved soil 4 can be appropriately distributed and discharged to left and right sides or one side at an arbitrary place.

  That is, first, in the plant in the site 1 which is comparatively small and limited, the work range is narrow and the conveyance route is also limited. However, according to the improved soil storage plant 100, the efficient unloading points A, B, C, D, E, and F are provided in the small-scale site 1, and the improved soil 4 is accurately conveyed to each point. Can be discharged.

  2ndly, in the case of the improvement soil 4 which mixes quicklime, the quality time limit of the product resulting from mixed quicklime is limited. Furthermore, depending on the shipping destination, whether or not it can be transported within the quality period is different, it is necessary to clarify and classify the shipping destination as well as the production date and time. Even with such a need, the improved soil storage plant 100 can be realized in a space-saving manner, so that the transportation destination can also be clarified and classified.

  Thirdly, the means for discharging to the point can selectively distribute and distribute the improved soil in any direction on the belt conveyor 10 in the three directions of the left and right sides and the both sides of the transport path. . Also, it is reasonable in terms of cost and convenience.

  Fourth, when loading a product into a dump truck, in a conventional plant, if the conveyor column is within the working range, the loading becomes an obstacle and the work cannot be performed efficiently. The forklift cannot move freely. However, according to the improved soil storage plant 100, the pillar for supporting the conveyor is deleted, so that the site can be used effectively, and the work efficiency is good.

  Fifth, the separation between the site 1 and the belt conveyor 10 and the separation between the belt conveyor 10 and the building 101 of the plant 100 can be utilized to the maximum.

  As mentioned above, although the best form about the improved soil storage plant 100 of this invention was demonstrated based on the Example, this invention is not limited to the structure described in the said Example, The range which does not deviate from the meaning The configuration can be changed as appropriate.

  For example, the movement of the transport carriage 50 may be manual or electric.
