Abstract

The invention relates to a plough accessory for crushing clods of earth. It has jib-like securing spars (1 and 2), a longitudinal spar (3) and also a number of bearing frames (4) for the work wheels (5) effecting the crushing. The accessory is designed as a longitudinal spar (3) which presses the work wheels (5) onto the soil, has a shock-absorbed compensation spring-suspension (springs 6) and is vertically adjustable and can be arranged on the plough in such a way that it can be adjusted and secured. In this way an individual adjustability of the device to practically all plough types is achieved. In addition, the height of compaction of the soil can be set exactly and can also be maintained as a result of the fixed arrangement on the tractor (advantage compared to tractor-pulled devices). <IMAGE>

Description

The invention relates to a plow attachment device comprising at least two two-part attachment beams, a longitudinal beam and at least one pivotable bearing caliper with a rotating disc. The equipment saves at least one operation and thus energy.

It is an object of the invention that the fastening beams are provided with extendable parts fastened to the vertical adjusting devices fastened by a connecting arm to the longitudinal beam, the pivoting bearing brackets being attached to the longitudinal beam by angular profiles.

Advantageously, the pivot bearing bracket is mounted on the ball pin in a rotatable plate arranged below the angular profile to which the upper support of the tension spring is attached, the lower support of which is attached to the pivot bearing bracket.

It has proven expedient that the upper support of the tension spring is provided with a stop.

The pivot bearing bracket is provided with an upper support and a lower support, with a shock absorber arranged between the supports.

The invention relates to an additional device for a plow comprising at least two two-piece attachment beams; along at least one swivel bearing yoke with a rotatable disc. The device saves at least one working operation. alsotenergy.

There are known devices for crushing lumps of soil after plowing which are coated after plowing. and have a complicated construction. Self-propelled devices are also used, but they are very complex and, in addition, are very energy-intensive.

A major drawback of the prior art devices is that they do not bring any energy or cost savings and, moreover, make it difficult to turn tractors in the field. Furthermore, after plowing the field, before sowing, it is necessary to treat the clods by crumbling the soil and compacting the topsoil so that the moisture retained in the soil is maintained. are other work tasks that increase energy and time costs.

In order to overcome the above-mentioned drawbacks and in particular to save energy, an additional plow attachment device according to the invention has been constructed, in which the fastening beams are provided with extendable parts mounted on vertical adjusting devices fastened by a connecting arm to the longitudinal beam. swivel bearing brackets with angular profiles are attached to the longitudinal beam.

An advantage of the device according to the invention is that the attachment device can be attached to any commercially available plow, such as a one-sided plow of different sizes, wherein for each plow blade the device has a multi-wheel bearing bracket.

The telescopic design of the fastening beams makes it possible to continuously adjust the width spacing between the plows. blade and work wheel. Furthermore, by adjusting the height of the longitudinal beam, it is possible to precisely adjust the working wheel thrust and hence the desired soil compaction and, moreover, by shifting the bearing brackets horizontally to precisely determine the working wheel angle to the plow blade.

The plow attachment device according to the invention is universally applicable for its easy interchangeability of working wheels by discs or variously shaped radial tools.

A further advantage of the plow attachment device according to the invention is that the mechanical height adjustment elements can be easily replaced at any time by hydraulic or pneumatic elements and furthermore can be perfectly monitored for the terrain. Individual bearing callipers fitted with pneumatic or hydraulic shock absorbers. Pneumatic elastic elements may be used instead of mechanical compression and / or tension springs.

6 of the resistance, such as the topsoil stone, is relatively delayed and returned to the working position.

Deflection or withdrawal of the plow during the operation is prevented by arranging the resilient elements on the plow attachment device according to the invention. When using this device, energy, such as fuel, is considerably saved and, moreover, time is evident from the above.

The relatively simple construction, which is additionally designed so that the plow attachment device according to the invention can be mounted on any commercially available plow, requires low production costs.

In order to achieve better cultivation of the soil, it is also possible to make the pivot bearing yoke 4 substantially wider or, by means of a push-on additional yoke, which can additionally be attached to the pivot bearing yoke 4, to expand it and thereby obtain working width over a wider area. Instead of the simple work wheels 5, spiral-shaped work wheels or cylinders can also be inserted into the pivot bearing yokes 4. The widening of the bearing brackets is a significant advantage especially for semi-mounted plows.

When using the plow attachment device according to the invention in a semi-mounted plow, it is advantageous to provide the attachment device with a steerable support wheel.
