Description

The invention relates to a device for preventing adhesions to a bar roller having the features of claim 1 and to a soil working machine having the features of the subordinate claim.In agriculture, bar rollers are used for soil working. As the name already states, the rod roller has rod-shaped elements or rods which are rolled over the ground. If the soil is wet and / or clayy, for example, adhesions can settle on the rod roller or on the individual rod-shaped elements over time. The bar roller is clogged and the result of the soil working is adversely affected. The floor treatment may then have to be terminated prematurely. In addition, subsequent cleaning of the rod roller soiled with adhesions is very complicated, time-consuming and cost-intensive.DE 85 12 300 U1 discloses a bar roller. DE 36 24 784 A1 discloses an apparatus for agricultural soil working.It is therefore an object of the present invention to provide an apparatus for preventing adherence to a dust roll and a soil working machine, wherein the above disadvantages are eliminated or at least reduced.The above object is achieved by a device for avoiding adhesions to a bar roller having the features of claim 1.The device comprises at least one scraper bar, in particular a plurality of scraper bars arranged side by side, for scraping adhesions on the rod roller. The device also comprises a fastening device. The fastening device is configured to fasten the device to the rod roller in such a way that it is arranged outside the rod roller and at a distance from the rod roller. The distance between the rod roller and the scraper strip can be, for example, in a range of 1 to 2 cm and can in particular be variably adjustable.The adhesions may be, for example. The material may be soil, clay and / or biomass.As a result, adhesions to the rod roller can be avoided or at least reduced by simple means. By means of the device, in particular the scraper strip, adhesions can be immediately scraped off or removed before they become larger and the bar roll becomes clogged. The disadvantages associated with the adhesions can be avoided. In particular, soil working is also possible under moist conditions. A time-consuming cleaning of the rod roller can be dispensed with.According to a further development of the device, the device can comprise a support rail. The scraper strip can be fastened to the support rail. The support rail and / or the scraper strip can each have a length which is at least as long, in particular longer, than the length of the rod roller. The support rail and / or the scraper strip each extend in particular over the entire length of the rod roller. A plurality of, in particular six, scraper strips (in particular at a working width of 3 m) can be arranged next to one another along the support rail.As a result, fastening of the wiper strip can be implemented with simple means. In particular, adhesions over the entire length of the rod roll can be prevented.According to a further development of the device, the support rail and / or the scraper strip can be configured such that the scraper strip can be fastened to the support rail in at least two different positions. In this case, in the different positions, a distance between the scraper strip and the rod roller is different in each case. In other words, the distance between the scraper strip and the rod roller can be varied or adjusted. This can be implemented by means of a first screw connection. For this purpose, it is possible, for example, to do so. The support rail and / or the scraper bar may be provided with elongated holes, in each of which a screw engages and can be screwed in different positions along the elongated hole.In this way, the distance between the scraper strip and the rod roller can be adjusted with simple means. As a result, the wiping process can be adjusted specifically to different types of adhesions or to different soils, for example.According to a further development of the device, the fastening device can comprise at least one receptacle for fastening and / or receiving one end of the support rail.As a result, the support rail or its end can be fastened or received with simple means.According to a further development of the device, the receptacle can be elongated and configured in such a way that the end of the support rail can be fastened within the receptacle in at least two different positions. In this case, in the different positions, a distance between the scraper strip and the rod roller is different in each case.In this way, the distance between the scraper strip and the rod roller can be adjusted with simple means. As a result, the wiping process can be adjusted specifically to different types of adhesions or to different soils, for example.According to a further development of the device, the support rail can have a rectangular cross section. The receptacle can have two at least partially plane-parallel receiving surfaces. The receptacle and / or the support rail can be configured such that the end of the support rail is or can be received in a form-fitting manner between the receiving surfaces. The end of the support rail can be fixed in the different positions by means of at least one fixing element. The fixing element can be designed in particular as a screw, shear screw or bolt. The support rail can be designed as a hollow profile, in particular a rectangular or square one.The fixing element can be mounted above and / or below the support rail. The fixing element can be designed (for example as a shear screw) such that it breaks when a correspondingly large force is exerted on the scraper strip and / or the support strip, for example by means of a clamped stone. In this case, the fixing element breaks, so that the support rail and / or the scraper strip is no longer fixed within the receptacle and can be displaced along the receptacle.By setting a correspondingly large distance between the wiper strip and the rod roller, the wiper strip can be "switched off" in a quasi-manner, i.e. put out of operation. By setting a correspondingly small distance between the wiper strip and the rod roller, the wiper strip can be "switched on", that is to say put into operation, so to speak.As a result, the adjustability of the distance between the scraper strip and the rod roller can be implemented with simple means. In addition, it can be ensured, for example, when the stone is clamped in, that the scraper strip and / or the device is not damaged.According to a further development of the device, the fastening device can have at least one fastening element with a first end and a second end. The fastening element can be fastened or can be fastened by its first end to the rod roller. This can be implemented by means of a second screw connection. The fastening element can be fastened or fastened with its second end to the receptacle. This can be implemented by means of a third screw connection.As a result, the fastening of the device to a rod roller can be implemented with simple means.According to a further development of the device, the fastening element can have a recess at its first end. The recess may be larger than a diameter of a shaft of the rod roller.This allows the device to be mounted on a rod roller with simple means. In particular, dismantling the shaft of the rod roller is not necessary in order to mount the device. Thus, a standard rod roll can be easily and quickly upgraded with the device.According to a development of the device, the fastening element and / or the receptacle can be configured such that the receptacle can be fixed or fastened at the second end of the fastening element in at least two different positions. In this case, in the different positions, a distance and / or an angle between the wiper strip and the rod roller (or an angle between the wiper strip and the fastening element) is different in each case.As a result, a distance and / or an angle between the scraper strip and the rod roller (or the fastening element) can be set as desired, for example, to different types of adhesions or to different soils, using simple means.According to a further development of the device, the wiper strip can be formed at least partially, in particular completely, from rubber, in particular hard rubber. It is likewise conceivable for the wiper strip to be at least partially, in particular completely, made of metal or PVC. The scraper strip can consist of several individual parts.As a result, the wiper strip can be implemented with simple means and at low cost. Possible damage to the scraper strip and / or the rod roller, which can be caused, for example, by a stone which is entrained along or clamped between the individual parts of the device, can be avoided or at least reduced, in particular on account of the elasticity of the scraper strip formed from rubber.According to a further development of the device, the support rail and / or the fastening device can be made of metal, in particular steel (stainless steel).As a result, the device can be implemented in a particularly robust manner.The above object is achieved by a soil working machine having the features of the subordinate claim. The soil working machine comprises a bar roller with a device according to the above explanations. The rod roller can also be designed as a curving roller. In principle, these types of rollers are particularly well suited for producing finer soil, since the roller rods, when they enter the ground, carry along a large amount of soil and throw it upwards.With regard to the advantages which can be achieved with the soil-working machine, reference is made to the relevant explanations relating to the device. For a further embodiment of the soil working machine, the measures described in connection with the device and / or the measures explained below can be used.According to a further development of the soil-working machine, the bar roller can have at least one rack, in particular a plurality of racks. The rod roller can have a plurality of rod-shaped elements (roller rods). The toothed strip can be arranged on one of the rod-shaped elements, for example at a 90° angle. A plurality of toothed strips can be arranged on a plurality of rod-shaped elements.As a result, the soil working and / or weed control by means of the soil working machine can be further optimized.According to a further development of the soil-working machine, the rack may have a plurality of, in particular triangular, teeth. A slot (or gap) can be arranged between each two adjacent teeth of the toothed strip. The rack, the teeth and / or the slots may be aligned along the direction of rotation of the bar roll. The individual teeth can each have a length of 3 cm (centimeters) and a width of 2 cm. The slots between the teeth may have a length of 3 mm (millimeters) and a width of 2 mm.During soil working, plants or plant parts can pass between the individual teeth of the rack, in particular into the slots, in particular become caught there, and can be torn out of the soil by the rotation of the bar roller and the movement of the racks associated therewith.As a result, the soil working and / or weed control by means of the soil working machine can be further optimized.According to a development of the soil-working machine, the soil-working machine can have at least one rubber tine. The rubber tine can be arranged at an adjustable distance from the bar roller, in particular behind the bar roller in the direction of travel or soil working direction. Thus, the rod roller can clean the rubber tine, in particular from longer straw or other plant residues accumulated there.As a result, the soil working by means of the soil working machine can be further optimized.According to a further development of the soil-working machine, the rubber tine can be fastened to the support rail, to a further support rail and / or to the fastening device.As a result, the attachment of the rubber tine can be implemented with simple means.Further features, details and advantages of the invention are evident from the wording of the claims and from the following description of exemplary embodiments on the basis of the drawings.
