Silo roller with hydraulically adjustable dozer blade

Abstract

Silo roller with a rotatably mounted compaction roller (3) and a pivotably mounted push shield (7), characterized in that a hydraulic cylinder (8) is provided, the cylinder housing of which is mounted on the frame via a pivot point (9) and the piston rod of which actuates a shield carrier (5) via a pivot point (10), on which the push shield (7) is mounted, so that the push shield (7) is adjustable between an upper compaction position and a lower pushing position.

Description

Technical field

[0001] The invention relates to agricultural implements for compacting and distributing silage, in particular a silage roller which combines a rotatably mounted compaction roller with a hydraulically actuated, swiveling push shield. State of the art

[0002] Conventional silage rollers are used exclusively for compaction. Distributing or pushing the silage is done with separate front-mounted implements. An integrated solution that combines compaction and distribution in one machine and allows for intermediate positions for pre-compaction is not yet available. Description of the invention

[0003] The silo roller combines a rotatably mounted compaction roller with a pivoting dozer blade, which is adjusted via a hydraulic cylinder mounted on the rear frame. The dozer blade is mounted on a blade carrier and can be positioned between an upper compaction position, a lower pushing position, and freely selectable intermediate positions, thus enabling simultaneous pre-compaction during spreading. embodiment

[0004] The compaction roller is rotatably mounted to a front frame section via roller bearings. The blade carrier is pivotally mounted to the front frame, and the dozer blade is attached to the blade carrier via a pivot bearing. The hydraulic cylinder is articulated at its rear pivot point to the rear frame section; its piston rod is connected to the dozer blade via the front pivot point and adjusts it between working positions. Advantages

[0005] Combination of compaction and distribution in one device; uniform layer thickness through pre-compaction during distribution; fewer machine changes; robust mechanics; optional increase in impact force through additional front shield (not part of the invention).

Claims

[1] Silo roller with a rotatably mounted compaction roller (3) and a pivotably mounted push shield (7), characterized by , that a hydraulic cylinder (8) is provided, the cylinder housing of which is mounted on the frame via a pivot point (9) and the piston rod of which actuates a shield carrier (5) via a pivot point (10), on which the push shield (7) is mounted, so that the push shield (7) is adjustable between an upper compression position and a lower sliding position. [2] Silo roller according to claim 1, wherein the shield carrier (5) is guided laterally outside the compaction roller (3). [3] Silage roller according to one of the preceding claims, wherein the push shield (7) can be operated in freely selectable intermediate positions, so that simultaneous pre-compaction takes place when distributing the silage, wherein the intermediate position is hydraulically adjustable and durable. [4] Silo roller according to one of the preceding claims, in which instead of a central hydraulic cylinder (8) two laterally arranged hydraulic cylinders are provided which are actuated synchronously in order to effect a symmetrical force application and a reduction of the tipping moment on the shield carrier (5).
