Abstract
An apparatus for withdrawing compressed fodder or similar agricultural material from a pile has an engaging tool which is mounted on a cantilever arm arrangement. This arrangement is capable of reaching over a quantity of fodder to be withdrawn and engaging behind the quantity from above so that the remainder of the material will not be loosened. The engaging tool shifts the quantity of fodder into a receptacle which is mounted on a common support with the cantilever arm arrangement, the support being adapted to be mounted on a tractor. Hydraulic cylinder-and-piston units connected to the hydraulic system of the tractor are used for moving the engaging tool into and from the receptacle.
Claims16
A method of withdrawing pressed agricultural material from a pile of such material, comprising the steps of separating a quantity of agricultural material from the pile including effecting the penetration of a tool into the pile from above and movement of the tool to separate said quantity while leaving the consistency of the remaining portion of the pile at least substantially unchanged;
- and introducing the separated quantity of material into a receptacle, said separating and introducing steps including pivoting the tool about more than two discrete parallel axes and independently of the receptacle.
Apparatus for withdrawing pressed agricultural material from a pile of such material, comprising vehicle-mounted supporting means;
- a mobile material engaging tool having a predetermined width;
- an arm for said engaging tool, said arm having a first portion articulately connected with said supporting means and a second portion articulately connected with said first portion and said tool;
- means for moving said engaging tool relative to said arm and for moving said portions relative to each other as well as relative to said supporting means so that said tool can be caused to penetrate into the pile of pressed material from above to separate a quantity of material from the pile while leaving the consistency of the remainder of the material of the pile at least substantially unchanged;
- and a vehicle-mounted receptacle pivotable between a plurality of positions and having an opening whose width at least equals said predetermined width, said receptacle being located in the path of movement of said tool so that the latter can enter the receptacle while advancing the separated quantity of material away from the remainder of the pile, said first portion of said arm being moveable independently of said receptacle.
An apparatus for withdrawing materials, particularly pressed fodder and similar agricultural materials, from a storage, comprising supporting means;
- an engaging tool;
- means for mounting said engaging tool on said supporting means for movement from a retracted position in a path over and from above behind a quantity of the material into an engaging position in which said engaging tool engages the quantity;
- means for moving said engaging tool in said path;
- and a receptacle of predetermined height mounted on said supporting means and operative for receiving at least a portion of the quantity of the material, said supporting means including a supporting frame extending substantially vertically in a position of use of the apparatus and having an upper portion and a lower portion, said lower portion being inclined relative to said upper portion and having a length substantially corresponding to the height of said receptacle.
