[0011]

However, the above-mentioned conventional pretreatment devices for soil improvement equipment have various problems in terms of work space, labor cost, treatment capacity, and the like.

That is, in the conventional pretreatment apparatus for soil improvement equipment using the rotary buckets shown in FIGS. 4 to 6, the rotary bucket 103 of the heavy machine 101 causes the soil A before the presorting to be mixed with the mixed matter B. Although it is separated into the soil C after the treatment, the rotary bucket 103 has a limit in the amount of pretreatment. On the other hand, the processing capacity of the soil improvement equipment is almost constant, and it is necessary to secure sufficient pretreatment capacity with respect to the processing capacity of this soil improvement equipment in order to increase the work capacity. Therefore, it is necessary to increase the number of heavy equipment 101 equipped with the rotary bucket 103 to increase the processing capacity, a large processing space is required, work efficiency is not good, and an operating staff for operating the heavy equipment 101 is also required. As a result, labor costs increased, and the work environment for workers was not good. Further, the rotary bucket 103 of the heavy equipment 101 is the bucket 10
Separation processing is performed by the blade 103c that rotates inside the 3a, and the blade 103c is frequently damaged and worn with respect to the processing capacity, resulting in high replacement cost and also because sorting work cannot be performed at the time of replacement. There is also the problem of reduced efficiency.

Further, in the conventional pretreatment device for soil improvement equipment using the grizzling device shown in FIGS. 7 and 8, the soil A before the pre-sorting is mixed with the mixture B by the grizzly 204 in the hopper 203. Although it is separated into the soil C after the pretreatment, since each grizzly 204 is fixed in the hopper 203, the force acting on the soil A before the pre-sorting for separation is in the hopper 203 by the heavy machine. There is a problem that it is only the force that acts by free fall when it is thrown in, and for example, soil with a high water content ratio or clay-based soil cannot be sufficiently separated. Therefore, in this case, the hopper 2 is
Although the grizzly 204 is vibrated and separated together with 03, the vibrating machine 207 has a limit in the magnitude and direction of the vibrating force acting on the soil A in the hopper 203 before pre-sorting, and ensures sufficient processing capacity. There is a problem that you can not.

Further, in the conventional pretreatment apparatus for soil improvement equipment using the rotary sieving apparatus shown in FIGS. 9 to 11, the soil A before the pre-sorting is carried into the rotating rotary cylinder 304,
By the sieve 305, the soil A before this presorting is mixed with the mixture B
The soil C after the pretreatment is separated into the soil C after the pretreatment, but the force acting on the soil A before the separation for the purpose of separation is only the force due to the rotating force of the rotating cylinder 304. There is a problem that the ratio soil or the clay-based soil cannot be loosened in the rotary cylinder 304 and cannot be reliably separated.

The present invention solves such a problem, and an object of the present invention is to provide a pretreatment device for a soil improvement facility, which has an improved sorting capacity.
