A device for protecting tires of agricultural machinery, consisting of a roller with attached to it, by means of welding operations, reinforcing bars, bearing assemblies, horizontal beam mounting brackets, shaft brackets, horizontal beam, shock absorbers, spring brackets, levers, rack, fastenings to the beam header, consisting of studs, nuts and rectangular plates with holes, which also contains adapter bushings of the racks, and the brackets for fastening the horizontal beam are made with the possibility of attaching to the adapter bushings of the racks, and one of the levers is made elongated, as a result of which the roller is installed at an angle to the trajectory of movement harvesters in such a way that when rolling, the stubble experiences an additional traumatic effect.

Description

Utility model Device for protecting tires of agricultural machinery refers to agricultural machinery and can be used for rolling and directional stubble laying during harvesting.

A 5000 Stalk Devastator device is known for protecting tires of agricultural machinery by rolling corn stubble (https://manualzz.com/doc/9338564/5000-022-series-stalk-devastator_patented), taken as an analogue and consisting of a rolling shaft with attached to it using welding operations, reinforcement rods, bearing assemblies, horizontal beam mounting brackets, shaft brackets, horizontal beam, racks, bushings with springs, spring brackets, levers and fasteners, consisting of studs, nuts and rectangular plates with holes intended for mounting the device for protection of tires of agricultural machinery to a beam of a harvester.

A disadvantage of the known device is the low efficiency in protecting tires of agricultural machinery from the impact of the stubble of agricultural plants, which consists in the insufficient efficiency of injuring the stubble with a roller during harvesting, as a result of which, due to elastic stresses, the stubble fibers return it to its original position.

The task to be solved by the claimed utility model is to increase the efficiency of stubble injury in the process of rolling it.

The technical result is achieved by the fact that the device for protecting tires of agricultural machinery, consisting of a stitching shaft with attached to it by welding, reinforcement bars, bearing assemblies, horizontal beam mounting brackets, shaft brackets, horizontal beam, shock absorbers, spring brackets, levers, racks, attachments to the header beam, consisting of studs, nuts and rectangular plates with holes, additionally contains adapter bushings of the racks, and the brackets for fastening the horizontal beam are made with the possibility of attaching to the adapter bushings of the racks, and one of the levers is made elongated.

Thus, the roller is installed at an angle to the trajectory of the header in such a way that, when rolling, the stubble experiences an additional traumatic effect as a result of the resulting friction-sliding, which, ultimately, will ensure its better injury and reduce the elastic stresses that return the stubble to the starting position, in which it poses a threat to agricultural tires.

The technical result is illustrated by drawings:

in fig. 1 - device for protecting tires of agricultural machinery (top view);

in fig. 2 - device for protecting tires of agricultural machinery (side view);

in fig. 3 - device for protecting tires of agricultural machinery (front view);

The device for protecting tires of agricultural machinery contains a stitching shaft 1, reinforcement rods 2, bearing assemblies 3, brackets 4 of the stitching shaft 1, a horizontal beam 5, a shock absorber 6, brackets 7 of a shock absorber 6, a lever 8, racks 9, attachments 10 to the harvester beam, transitional bushings 11 racks 9, brackets 12 for fastening the horizontal beam 5, elongated lever 13.

Device for protecting tires of agricultural machinery works as follows.

The stubble remaining during the operation of the harvester falls under the action of the stitching shaft 1 with the bars 2 of the reinforcement installed on it, which through the bearing assemblies 3 with the help of the brackets 4 of the stitching shaft 1 is fixed on the horizontal beam 5, which is connected with the help of the brackets 12 for fastening the horizontal beam 5 with adapter sleeves 11, which are fixed on the racks 9, connected to the lever 8 and the elongated lever 13, which are mounted on the header beam with the help of fasteners 10 to the harvester beam, which are additionally connected to the racks 9 by means of brackets 7 and shock absorbers 6, moreover, due to the difference in the length of the lever 8 and the elongated lever 13, the horizontal beam 5 and the roller 1 mounted on it are located at an angle to the direction of movement of the harvester, as a result of which, during rolling between the stubble and the roller 1, friction-sliding forces additionally arise, which leads to better stubble injury.

Claims (1)
