Title: Refuse loading deice in refuse gathering car
Inventor: IKUNO MASAMITSU
IPC: B65F3/20
Filed: 1988-02-16
Abstract: PURPOSE:To simplify the constitution of the device in the title and load refuse densely by supporting a deflector so that its upper end can slant to the refuse storing box side with the supporting shaft on its lower end kept as its center while the deflector being energized to the reuse storing box side. CONSTITUTION:In a normal status, the upper end of a deflector 8 is slant mov able in its nearly horizontal position. Accordingly, refuse pushed in by a pushing panel 4 are pushed downward through the deflector 8 and loaded into the storing box 1. The upper end of the deflector 8 is pushed upward by the force of refuse in response to the increase of a stored amount. While, as the deflector 8 is energized toward the inside of the storing box 1 by a spring 10, the refuse is subjected to compression force by the deflector 8. Thus, the refuse in the refuse storing box 1 is always subjected to uniform pushing-in force until a full status of the box is attained from its empty status and refuse loaded densely in the storing box 1. By this constitution, the constitution can be simplified and dense loading can be performed.
