Description

The invention relates to agricultural engineering, in particular to tools for rolling soil.

Known tool for rolling the soil [Patent RU 2734479 C1. A tool for compacting the soil. Published on October 16, 2020 Byull. No. 29], which includes mounted on a frame one after another, provided with axles rollers, made in the form of hollow cylinders of the same diameter. On one side of the rollers, a variator is installed, consisting of pulleys and a belt drive. The front roller pulley is rigidly mounted on the base of the hollow cylinder, and the rear roller pulley is rigidly mounted on its axis. On the other side of the rollers, a variator is also installed, and the pulleys of the front and rear variator rollers connected by a belt are rigidly mounted on their axles. Imbalances are installed on their axes inside the hollow cylinders of the rear and front rollers. The imbalances are made in the form of rods pivotally mounted on the axes of the front and rear rollers, which can be fixed in a given position relative to the roller axis. Weighting agents are installed on the rods with the possibility of fixing them in a predetermined position relative to the axis of the rods. On the other side of the rear roller, an asterisk is rigidly mounted on its axis, connected by a chain with a sprocket rigidly mounted on the axis of the front roller.

The disadvantage of this tool is the high consumption of materials and the large dimensions of the tool.

The technical result achieved when creating the invention is to reduce the size and material consumption of the tool.

The technical result is achieved by the fact that a variator pulley is installed on the roller axis. The frame is equipped with a bracket with a shaft installed parallel to the roller axis. A driven pulley and a variator pulley are installed on the shaft. The driven pulley is connected by a belt to the driving pulley. The variator pulley mounted on the roller axle is connected by a belt to the variator pulley mounted on the shaft.

FIG. 1 shows a general view of a tool for rolling soil, FIG. 2 - the same, top view, in Fig. 3 - section along AA.

The tool for compacting the soil is supported by a roller 3, mounted on the frame 1, equipped with an axis 2, made in the form of a hollow cylinder. On one side of the roller 3, a drive pulley 4 is rigidly mounted on its base. Inside the hollow cylinder, on its axis, imbalances are installed, made in the form of rods 5 pivotally mounted on the axis 2 with the possibility of fixing in a given position relative to the roller axis using bolts 6. On the rods 5 7 weights are installed with the possibility of fixing them in a given position relative to the axis of the rods using bolts 8.

A variator pulley 9 is rigidly mounted on axis 2. Frame 1 is equipped with a bracket 10 with a shaft 11 installed parallel to the axis 2 of the roller 3 11. On shaft 11 there is a driven pulley 12 and a variator pulley 13. The driven pulley 12 is connected by a belt 14 with a driving pulley 4. Pulley variator 9, mounted on the axle 2 of the roller 3, is connected by a belt 15 with the variator pulley 13 mounted on the shaft 11.

Also on the frame 1 there is a hitch 16, which is pivotally connected to the frame 1 by means of pins 17.

The tool for compacting the soil works as follows.

With the help of the towing device 16, the soil compaction tool is aggregated with the tractor. Pre-weights 7, installed inside the hollow cylinder of the roller 3, are fixed in the required position both relative to the length of the rods 5 using bolts 8 and relative to the axis 2 of the roller 3 using bolts 6.

When operating the tool for rolling the soil on heavy soils, the weighting agents 7 are shifted along the rods 5 to their edges, and the rods 5 are installed in the same plane and in the same direction relative to the axis 2. When working on light soils, the weighting agents 7 are shifted along the rods 5 to the axis 2 of the roller 3 , and the rods 5 are sequentially directed in opposite directions.

After that, the movement of the unit begins. Roller 3 starts to rotate, compacting the soil and crushing the soil clods. The roller 3 drives the drive pulley 4 into rotation, which, through the belt 14, rotates the driven pulley 12 rigidly mounted on the shaft 11, which is mounted on the bracket 10. Together with the shaft 11, the variator pulley 13 mounted on it, connected by the belt 15 with the variator pulley, begins to rotate 9, rigidly mounted on the axle 2 of the roller 3. In turn, together with the axle 2 of the roller 3, the imbalances installed inside the roller 3 begin to rotate.

When transferring rotation from the driving pulley 4 to the axle 2 of the roller 3 due to the installation of the variator, the rotation frequency of the imbalances installed on the axle 2 is increased in comparison with the rotation frequency of the roller 3. This leads to oscillations that intensify the effect of the roller 3 on the soil. At the same time, the required quality of crumbling soil lumps and compaction of the soil by the roller 3 is ensured, while the dimensions and material consumption of the tool are smaller in comparison with the prototype.

Thus, installing the variator pulley on the roller axis, supplying the frame with a bracket and installing the shaft parallel to the roller axis, installing the driven pulley and the variator pulley on the shaft, connecting the driven pulley with a belt to the drive pulley, as well as connecting the variator pulley mounted on the roller axis , with a variator pulley mounted on the shaft leads to a reduction in the size and material consumption of the tool.
