Abstract

Mowing basket for the cleaning of water ditches, which can be mounted on any hydraulic excavator. The mowing basket works parallel to the direction of travel, and consequently the two slopes and the ditch bottom can be mown in one operation. The object on which the invention is based is to eliminate technical defects of the conventional mowing basket (Dutch Patent Specification 1,482,014). These technical defects are overcome if a rotating cutter roller is used instead of the cutter bar. Each individual cutter is fastened by means of a bolt and a shearing pin, so that, in the event of contact with foreign bodies, the shearing pin breaks and the cutter can shift aside. As a result of the simple and time-saving use of a shearing pin, the mowing basket is fully capable of use again. Another advantage is that there is no abrasion of mowing cutters, since these move freely. Also, shrubbery growing wild and often found on ditch slopes can also be mown down without wear by means of the mowing basket. The plant material mown by the roller is collected by the following basket. It can be dumped again at any location.

Description

Mälilcorb

Invention of a Mowing Device The invention relates to a mowing basket, in particular for cleaning water ditches, which are mounted on any hydraulic excavator of the conventional type can be. The mower basket works parallel to the direction of travel of the working machine Both embankments and the bottom of the trench can be mowed in one operation. Of the Invention is based on the problem of technical shortcomings caused by the structure the conventional cutter bar with downstream grass collector.

The disadvantage of the cutter bar (Dutch patent no.

14 82 014) consists in the fact that a knife transversely to the working direction is guided through the knife fingers in a back and forth motion there is a high level of wear and tear, as sand between the blades when mowing the bottom of the trench and fingers got. Through foreign bodies (posts, stones, wire), which not always Knife blades and knife fingers often break if they are visible on the bottom of the trench the end. Changing knives is costly and time consuming. These disadvantages will be switched off if, instead of the cutter bar, one arranged transversely to the working direction is switched off rotating roller with helically attached knives is used. Every single one Knife is attached with a bolt and a shear bolt, so that when touched with frame bodies the shear bolt breaks and the knife can evade. By simple and time-saving insertion of a shear bolt, the mower basket is fully operational again Another advantage is that there is no abrasion of mower blades, since these move freely. Wild shrubs that is often located on ditch embankments, can be mowed with no wear and tear. That Vegetable material cut by the roller is collected by the downstream basket. It can be poured out again at any point. The mowing basket is additional equipped with a cutting edge located below the roller. The cutting edge ensures an even distance to the ground during the mowing process and prevents roots from being torn out.

A basic clearance can also be carried out with the knife at a standstill will.

A trench 1 is made with a working machine 2 with a basket 3 from the vegetation 4 cleaned, with guidance and angle of incidence of the Llähkorbes from the carrier machine 2 is adopted. The oil motor to drive the mower roller is also from the Wlragermaschine 2 actuated.
