問題点があった。As a solution to the above-mentioned shortcomings, the
As shown in No. 9-176514, it has been proposed to attach an air cylinder to the lower end of the rod of a hydraulic cylinder, connect a floating weight to the lower end of the piston rod of the air cylinder, and raise and lower the floating weight. In this case, the frame above the hopper is high due to the difference in the stroke of the stroked air cylinder of the floating weight, which is a serious disadvantage in that it may not be possible to install it in places where ceiling height is restricted. Furthermore, since the air cylinder is also used for lifting and lowering, there is a problem in that the amount of reduction in the consumption of high-pressure air is also small.

通ってクッションシリンダ２３と連結されている。The present invention provides a lifting cylinder whose upper end of a piston rod is connected to a hopper upper frame, a cushion cylinder having a double structure with the lifting cylinder, a connecting rod connected to the lower end of the cushion cylinder, and a cushion cylinder which has a double structure with the lifting cylinder. The apparatus of the present invention is characterized by having a floating weight attached to the lower end of the rod. [Function] In the device of the present invention, hydraulic oil is supplied to and discharged from the lifting cylinder. In Figures 1 to 3, reference numeral 21 denotes a floating weight, to which a connecting rod 22 is connected to the upper end of the floating weight.
is connected to the cushion cylinder 23 through a connecting rod guide portion 30 provided at the upper end of the hopper 31.
クッションシリンダ２３のピストン２８のロッド内には
昇降用シリンダ２５が設けられており、昇降用シリンダ
２５が挿入できるよう連結棒２２は中空となっている。A lifting cylinder 25 is provided within the rod of the piston 28 of the cushion cylinder 23, and the connecting rod 22 is hollow so that the lifting cylinder 25 can be inserted therein.

である。A frame structure including a guide lock and a top plate 32 is provided at the upper part of the hopper, and a rod 26 of a lifting cylinder 25 is connected to the top plate 32. Guide rod 27
is the guide 24 provided in the cushion cylinder 23
The cushion cylinder 23 is vertically movable.
