SK42194A3 - Device for removing of weed copse from roads, squares, parks etc. - Google Patents

Abstract

The invention relates to an implement for removing weeds from paths, squares, parks, etc., which in particular have a covering of gravel; chippings, sand, etc. The implement has an implement carrier with at least one movable component, on which is mounted at least one tool to be brought into contact with the ground. So that the implement has a high cleaning action, whilst causing only limited damage to the ground, the tool has a shoe-like base part, which has blades on its leading edge pointing in the travel direction and on its lateral edges and with which it at least partly penetrates the ground and that the tool performs an oscillatory movement substantially directed transversely to the travel direction. The tool can be downwardly inclined in the travel direction. The base part is substantially plate-like and the blades are formed by the downwardly curved marginal areas of the base part.

Description

The object of the invention is a device for removing weeds from roads, squares, parks having a surface mainly of gravel, sand, gravel and the like, consisting of a vehicle having at least one movable component on which at least one tool is mounted, which prit

k. comes into contact with the soil.

UoteraiSi state of technology.

Over time, weeds and other undesirable vegetation grow on these areas and must be removed at regular intervals. Previously, chemical agents, so-called herbicides, were used for this purpose or weeds were burned. Both of these methods are now prohibited, at least in the field of trade and public administration.

For this reason, weeding devices, weeds are being developed which have rotating brushes or combs with which weeds are to be plucked. Other known devices of this kind have a screw which is located across the direction of travel of the device and which slightly penetrates the surface layer of the soil. The two devices described above have a common drawback in that they degrade and sweep the top layer of soil onto the treated area thus requiring further scale adjustments. In addition, the described devices do not have sufficient power.

From the German patent side and a considerable device for removing knives that can penetrate the file no. No. 356,512 is a known weed having a greater number below the soil surface. The machine also moves blades, which should thus cut the weed ride. However, it has been shown that the efficiency and performance of such a machine are insufficient.

L of German published patent application no. 32 11 152 Al is a known device having a series of tools made as knives arranged on a common support. The tools enter the soil while the slide rotates. In such a process, the surface layer of the soil is greatly stripped and moved, so that subsequent treatment of the treated area is to a large extent necessary.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a plant design in which the drawbacks of the known devices are eliminated and, moreover, high weed efficiency and performance are achieved without causing significant damage to the soil surface.

This problem is solved and the shortcomings of known devices of this kind are largely eliminated by the device for removing weeds from roads, squares, parks and the like, which is the object of the invention, which consists in that the tool of the device consists of a shoe-shaped base part. its cutting edges in the direction of travel of the front edge and on its side edges, by which it extends at least partially into the soil, the tool performing an oscillating movement which extends substantially across the direction of travel.

The above-described shoe base part of the tool penetrates its cutting edges below the top of the soil during operation. The movement of the base parts across the direction of travel can be achieved by a linear reciprocating or oscillating rotary drive. A frequency of approximately 400 oscillations per minute has been proven. The oscillating movement of the tool is preferably achieved in that the part mounted on the body of the device moves back and forth substantially across the direction of travel. Cutting edges of coulter direction; ··· 1:

and the three shape of the board by the peripheral base plucked the weeds from the soil without the weeds being torn or cut off. In this way, weeds are thrown onto the surface of the soil, while gravel, sand and the like fall immediately downwards, because the separation of the soil from the weeds is caused by gravitational forces.

It is advantageous if the tool is inclined downwards in the direction of travel, as this permits penetration of the tool into the soil.

Furthermore, it is advantageous if the tool base part has substantially and cutting edges sU formed by the downwardly curved areas of the base part. In this way, below the plate-shaped portion, a space is formed defined by downwardly curved edge regions of the base portion.

in

Thus, the shoe tool has a concave shape. The back of the tool is not bent down and remains open. The cutting edges formed by said curved regions of the base portion may be formed such that they form a certain general angle, for example, that they converge at the front so that they have a triangular or arcuate shape and are connected by a connecting region to an oscillating driven part of the device. However, it is generally preferred that the side edges of the tool are substantially perpendicular to. its front edge.

The shoe-shaped tool may have the shape of a spade or a suitable blade, which is oriented with the convex side upwards. It can also be made in the form of an animal lamb or the like. It can also be arched upwards.

in the form of a plate with bent down, etc.

Instead of the base part by the marginal regions, it is possible to use apical converging side edges.

w

Furthermore, it has been found to be advantageous if the solid element with the areas located between the cutting edges is larger than the cross-section of the tool connecting areas by means of which the tool is connected to the part which performs the oscillating movement. In this way, clogging with weeds plucked from can be avoided

land that has on its roots and between them always a certain amount of land. A width in the range of up to 10 cm and a length in the range have proven advantageous. 2 to 10 cm, most preferably su. however, the dimensions range from 3 to 8 cm.

Preferably, the tools are oriented substantially transverse to the side-by-side direction in at least one row. The distance between the tools should be such that the paths of movement of the two adjacent tools overlap one another. The solution is particularly advantageous in that the tools are arranged in two rows spaced one behind the other. The front row tools can operate counterclockwise to the rear row tools. In order to achieve pre-processing with the front board tools and the rear board tools to complete the operation, the front board tools may be constructed differently from the rear board tools.

to the soil and the component placed movable substantially across

All tools of a single row can be placed on a common beam that moves back and forth, or there can always be one tool or multiple tools located on its own beam or lever that moves back and forth. At least one of the tools is pivotable or oscillating across the direction of its movement. It is also advantageous if at least one of the tools is adjustable in a direction perpendicular to the carrier and is reversible to the direction of travel. An advantageous solution also consists in that the tools can be adjusted in the vertical direction relative to the reciprocating part and the reciprocating part is adjustable in the vertical direction.

It is preferred that at least one of the tools is activated by the silo container towards the soil. Preferably, the force reservoir is a weight or spring.

• J

Furthermore, it is advantageous if two tools are spaced apart in the direction of travel, which work in counter-contact on a lever which operates as a two-arm and is pivotable about the b-axis extending approximately perpendicular to the treated soil. one pair of front row tools and one rear row pair. The tools then move along circular arc paths.

It is advantageous if several tools are arranged side by side in the front row and in the rear row, the tools of one row being driven synchronously. The two adjacent tools are located in pairs at the end of the two-arm lever, which is pivotable about an axis at least approximately perpendicular to the treated soil. In this case, a pair of front row tools as well as a pair of rear row tools are located on this two-arm lever. The two-arm lever is pivoted. At least some of the tools are directed and / or positioned such that the cutting edge, when reciprocating forward, penetrates deeper into the soil than the cutting edge that is reciprocating rearwardly.

Preferably, at least one double-arm lever is positioned between the two outer two-arm levers, each carrying a pair of front row tools and a pair of rear row tools. It is preferred that the pairs of adjacent tools of the front row and / or the rear row are located on a common strut that is pivotable at least approximately perpendicular to the plane of the reciprocating movement.

One of the two-arm levers is coupled to the crank gear of the device and all the two-arm levers are kinematic coupled to each other

Especially for devices in which there are more than two tools in one row, it has proved to be particularly advantageous if the tools are not rigid but can be adjusted relative to the device and / or the lever and / or the beam. However, a solution is also possible in which the beams or levers, on which one or more tools are placed, are displaceably or pivotably positioned relative to the device or its fixed part. In this case, the tools must then adapt to soil inequalities. It is preferred that the support part of the device 6

The oscillating moving parts are vertically adjustable in which the oscillating moving or oscillatingly pressed in the direction consists of a plurality of mutually oscillating sections which are mutually positioned in the manner of a parallelogram. In this solution, the carrier part of the device can be adapted to the soil profile to be treated. The tools can be positioned relative to the oscillating device, i.e. the beam, for example, in a self-directed direction. Such folding or pivoting tools may also be used, or the component may be folding or pivoting relative to the carrier portion of the device. It is preferred that this tilting or rocking is transverse to the direction of travel of the device.

In this case, it can be advantageous if the movable tools are able to move the components by means of the force reservoir to the ground. This force reservoir ensures that a certain pressure is applied to the working surfaces of the tools and that the cutting edges of the tools enter the soil as evenly as possible. Depending on whether the oscillating part or only the tool itself is adjustable relative to the carrier part of the device, it may be advantageous if the power reservoir acts on either the oscillating part or the tools. A weight can be used as a force reservoir, i. j. additional weight, or self-weight of oscillating components, or spring (s). However, the power reservoir may be a hydraulic cylinder with a pressurized medium or a hydraulic motor and the like.

When using double-arm levers, which always carry a pair of front row tools and a pair of rear row tools, as carriers for a pair of tools, it may be advantageous if the pivoting axes of the side edge levers of the device are firmly attached to its support and the two-arm levers are carrier so that one of these extreme. adjustable levers. The design can be made with two-arm levers is directly connected to the crank gear of the device and the oscillating movement to the other double-arm levers is transmitted by a suitable clutch. A cable tensioned between two-arm levers, a rod linkage system or a hydraulic system may be used as a coupling. It has proven to be advantageous that the two-arm levers are hinged freely and are supported by force reservoirs, e.g. said springs.
