PROBLEM TO BE SOLVED: To provide a granular material collection device allowed to be stably opened/closed while causing few or no operation failures due to biting of granular materials with a simple structure.SOLUTION: A granular material collection device A includes a collector body 1 provided with a suction connection pipe 12 connected to an air suction source 2, a material introduction pipe 13 for receiving air-transported granular materials, and a discharge pipe 14 having an inclined opening end surface 14a, a lid body 28 for opening/closing the opening end surface 14a, and two arm parts 22 arranged on the opening end surface 14a to suspend and support the lid body 28. Each of the arm parts 22 is drooped in a standby state where the suction force of the air suction source 2 and the load of the granular materials are not acting on the lid body 28, and both ends thereof are connected to be rotatable around axes 18 and 26 in the same direction as that of the open/close shaft of the lid body 28.SELECTED DRAWING: Figure 1 |
