Abstract

The cutting tool on plant harvesters is used in plant breeding areas of forestry, vegetable and ornamental plant production. The aim of the invention is to arrange a cutting tool on a plant harvester in a structurally simple form and for a reliable operation, which has the task of severing the side roots in the intermediate rows of planted beets with simultaneous soil loosening. According to the invention, the object is achieved by fixing vertically oriented knives in the form of right-angled triangles, one side of which represents a sharpened cutting edge, on the rewinding rods of an undercut slotting device.

Description

- Δ - £ * tU Ο4.Ο

The apparatus according to FIG. 1 consists of the undercutting shaker in the following arrangement: An undercut blade 1 which is adjustable in the angle of attack provides a horizontal cut below the surface of the bed at an adjustable depth and cuts through the vertically directed plant roots. The floor, which is above the cutting plane, slides over the knife as the machine advances and is raised depending on the set angle of the knife. At the rear edge of the knife, a shaft 2 is rotatably mounted, are fixed to the Rüttelstäbe 3, which form a plane in the basic position with the knife. At work, the Rüttelstäbe move 3 - driven by an eccentric - by a certain amount upwards and downwards alternately beyond the basic position. In accordance with the arrangement of rows of the bed according to the invention triangular knives 4 are mounted on the vibrating bars 3 arranged in the middle of the intermediate rows. The sliding in the work on the Unterschneideschar 1 floor with the rows of plants standing in it moves over the up and down moving Rüttelstäbe 3, is relaxed and partially falls down. The moving with the Rüttelstäben 3 4 cut the side roots between the rows. The rows of plants have, arrived at the rear end of Rüttelstäbe 3, nor the almost same row structure as in pristine bed on, but are raised in height level at this point across the bed clearly compared to the original state and stand in loose soil.

Claims (1)

Invention claim: Cutting tool on plant harvesting machines, arranged on a vibrating bar and consisting of a known knife (4), characterized in that this knife (4) is formed as a preferably right-angled triangle on the vibrating bar (3) perpendicular so that one of the two, the right angle enclosing sides on the vibrating rod (3) is fixed, the other points counter to the working direction and the third side is a preferably straight, sharpened cutting edge. For this 1 page drawings Field of application of the invention The invention relates to knife-like tools and their arrangement on an assembly for soil loosening of plant harvesters. Such tools are used on machines for plant harvest in plant nurseries of forestry, vegetable and ornamental plant production. Characteristic of the known technical solutions Priority will be z. For example, according to US-PS 3693721 rigid cutting tools of different shape for cutting the side roots in the intermediate rows of flowerbeds applied with beets or passive instead of the rigid knife or driven in the ground running discs (also called disc plate) used for the same purpose. According to DE-OS 2644769, the severing of the horizontally and vertically extending roots by J-shaped knives, which perform an oscillating motion in the ground in the direction of travel. A piercing-oscillating movement engaging in the ground from above performs circularly curved knives according to DD-PS 150535 and produces a shaped cut on horizontal and vertical roots of plants in rows. The latter technical principles are designed for a shape cutting of the roots for the design of a special root system and not for the implementation of cutting measures at the roots to facilitate the mechanical plant harvest. Their use for this purpose requires the least possible undiluted soil, which should remain largely un-loosened even after performing the shape cut. Therefore, the tool engagement takes place in the soil from above each between the plant rows. The technically easy-to-solve vertical section between the rows of plants by passive or driven Kolterscheiben affects when assigned to a harvester in two ways disadvantageous: First, such cutting tools reach to be cut through lateral roots, due to the lateral and downward root development, only in greater depth and on the other hand, because they are guided from the top down into the ground, a significant obstacle to a continuous sliding of the cutting in the soil in loosening and absorption of the plants. Such congestion effects also occur in the aforementioned principles with actively moving oscillating knives limited on. The Gunn pint lifter (Aldhous, J.R., Nursery Practice, Forestry Comm. Bull.43.1972) alleviates this problem by having knife-like cutting tools mounted on a rigid horizontal undercut blade and directed backwards / forwards against the direction of work. Object of the invention The aim of the invention is to propose for a plant harvester in a structurally simple form and for a reliable operation, a cutting tool with a special arrangement and cut, which preferably cuts in the lower side roots. Explanation of the essence of the invention Object of the invention The invention has for its object to arrange a per se known cutting tool in the form of a triangle as a knife so that with a short knife guide the root incision in the ground from bottom to top with simultaneous soil loosening is to take place. Features of the invention According to the invention the object is achieved in that perpendicularly mounted knives are mounted in the form of right triangles on the Rüttelstäben an undercutting shaker, shown that one of the two, the right angle enclosing sides rests on the Rüttelstab, the other opposite to the direction and the third side is a straight sharpened cutting edge.
The invention will be explained in more detail with reference to an embodiment. In the accompanying drawing show: Figure 1: Undercut vibrating unit with mounted on the Rüttelstäben knives.
