Abstract
Abstract A travelling hopper and loader has a swivelling support member with a vertically adjustable feed boom and a vertically adjustable discharge boom connected thereto.
The inboard end of each boom is provided with an upwardly extending arm. The feed boom carries a hopper with a ground-engaging support depending therefrom. The hopper extends substantially all along the length of the feed boom. A hydraulic cylinder is connected between the feed boom and the support member.
The inboard end of each boom is provided with an upwardly extending arm. The feed boom carries a hopper with a ground-engaging support depending therefrom. The hopper extends substantially all along the length of the feed boom. A hydraulic cylinder is connected between the feed boom and the support member.
Description
This invention relates to a travelling hopper and loader having a swivelling hopper member with a vertically adjustable feed boom and a vertically adjustable discharge boom connected thereto. The inboard end of each boom is provided with an upwardly extending arm.
This type of travelling hopper and loader is arranged to minimize the stresses on the support member caused by impact forces, for example, the load caused by emptying an excavating shovel. By reducing the stresses on the support member it and its related bearing can be of less massive construction.
Further, the hopper extending along the length of the boom results in the ability to load it from several positions none of which are critical. The configuration of the hopper is such as to be stable during loading and operation~
The invention relates to a travelling hopper and loader comprising: a rotatable support member with a vertically adjustable feed boom and a vertically adjustable discharge boom pivotally connected thereto each having an upwardly directed axm at its inboard end, a hopper extending along and above the feed boom and having a ground-engageable support at an outer end thareof; a first hydraulic cylinder connected between the feed boom and the support member; and a second hydraulic cylinder connected between the upper ends of the arms.
The travelling hopper and loader of this invention has the advantages that the elongated hopper can be loaded from many positions and that the impact forces are transferred to a ground-engaging support and not applied to various pivot points. During the loading of the hopper ,~
,.: 1 ~ L2~i~;01~
the hydraulic cylinder controlling the posltion of the feed boom can be relieved of pressure so tha-t forces are not transferxed through it to the remainder of the apparatus.
Further, the movement of the centre of gravity of the support member is reduced thereby permitting the pivot connection and base support to be small.
The invention will now be described in terms ; of the particular embodiment shown in the drawing which depicts a side view of a travelling hopper and loader.
The apparatus has a base support formed by a crawler arrangement 1 carrying a ring 2 and a support member 3 mounted on a ball-bearing for swivelling movement. A
, feed boom 4 is pivotally attached to support 3 for vertical movement. Feed boom 4 in turn carries a hopper S having a ground-engaging support 6 at its outer end. Hopper 5 extends practically the whole length of the feed boom.
Hydraulic actuating equipment 7, hereinafter called a hydraulic cylinder, is connected between ring 2 and feed ; boom 4. In operation the boom and hopper are supported by support 6 engaging the ground and hydraulic cylinder 7 is relieved of pressure.
' A discharge boom 8 is pivotally connected to support member 3 on the opposite side from the feed boom and adapted for vertical movement. Each of booms 4 and 8 have upwardly extending arms 9 and 10 secured thereto and a further hydraulic cylinder 11 extends between the upper ends of arms 9 and 10.
6~;0~8 For transport, the feed boom 4 is lif-ted by hydraulic cylinder 7 and the discharge boom 8 raised by hydraulic cylinder 11. The coupling provided by hydraulic cylinder 11 results in feed boom 4 being partially counter-balanced both in the operating and transport modes of the apparatus. Since hopper 5 is empty during transport, only small forces are applied to hydraulic cylinder 7.
Once the feed boom 4 rests on support 6 there is little movement of the centre of gravity of the apparatus, thus providing stability. This configuration results in impact loads caused by material fed to the hopper passing through the support to ground. The hopper can be simultaneously loaded by several adjacent power shovels resulting in large amounts of material falling into it.
The apparatus of this invention avoids the resulting forces affecting the ring 2 and crawler 1.
