摘要： PROBLEM TO BE SOLVED: To provide a screw type transferring/crushing device economical and capable of being minimized in making the rotary speed of an internal screw and an external screw different.
SOLUTION: The device is equipped with the internal screw 3 forming a screw blade to a screw shaft 4 in spiral shape, and the external screw 6 which is coaxially disposed with the internal screw 3 and consists of a hollow-shaped screw blade 7 formed in spiral shape. The screw type transferring/crushing device 1 performs transferring and crushing an object to be treated, and is coaxially disposed with the internal screw 3. It has a basic sun gear 15 integrally rotating with the internal screw 3 and a basic planetary gear 16 which is engaged with the basic sun gear 15, connected with the external screw 6 and rotates the external screw 6 by the orbital motion. It is equipped with a differential speed mechanism 13 which gives the difference of the rotating speed between the internal screw 3 and the external screw 6, and the internal screw 3 and the external screw 6 are rotated with a motor M through the differential speed mechanism 13.

摘要： PROBLEM TO BE SOLVED: To provide a structure for preventing sand from being accumulated in an object installed in a waterway, which can prevent the accumulation of grit on its upstream side of the object, installed in the waterway, such as a sediment crusher in a structurally simple manner, and which can eliminate an influence on a movable mechanism part, caused by the sand.
SOLUTION: This structure comprises a screen 6 for the transmission of the grit, which is installed to the bottom of the waterway on the upstream side of the sediment crusher 1, and a bypass 7 which is formed below the sediment crusher 1 so as to make the screen 6 communicate with the downstream side of the sediment crusher 1. In the structure, the grit flows to the downstream side via the screen 6 and the bypass 7.
