Claims

[Claims for Utility Model Registration] (1) In a power spreader 10 equipped with an engine, a shutter case that is disposed at the bottom of a spray tank 20 for storing spray material and partitions the outlet 26 of the spray tank 20 inside. 24 and said outlet 26
a shutter 28 supported by the shutter case 24 so as to be able to adjust the opening degree thereof; and a stud bolt 3 extending vertically upward from the shutter case 24.
6, a shutter cover 39 into which the stud bolts 36 are inserted so as to be freely displaceable in the vertical direction and which covers the upper part of the shutter 28; and a shutter cover 39 which is fitted into the stud bolts 36 from the top and bottom of the shutter cover 39, respectively, to move the shutter cover 39 in the vertical direction. An outlet structure of a spray tank for a power spreader, characterized in that the structure includes coil springs 40 and 52 that bias each other in opposite directions. (2) In the power spreader 10 equipped with an engine, there is a shutter case 24 disposed at the bottom of the spray tank 20 that stores the spray material and partitions the outlet 26 of the spray tank 20 inside;
a shutter 28 supported by the shutter case 24 so as to be able to adjust the opening degree thereof; and a stud bolt 3 extending vertically upward from the shutter case 24.
6 and the stud bolt 3 in the insertion hole 50.
a shutter cover 39 that is inserted through the shutter cover 39 and covers above the shutter 28; and an elastic body that is interposed between the insertion hole 50 of the shutter cover 39 and the stud bolt 36 and elastically deforms in the lateral direction of the stud bolt 36. 54. An outlet structure of a spray tank for a power spreader, comprising:
