Description

The utility model relates to agricultural engineering, in particular to soil cleaners of root crops.

Known cleaner of root crops from soil [Patent RU No. 187599, Publ. 13.03.2019, Bul. No. 8], containing installed on the frame with the possibility of rotation in one direction cylindrical rollers. The rollers are interconnected by sprockets. The sprockets of the even and odd rollers are installed outside the frame from different sides with the possibility of rotation of the even and odd rollers at different frequencies.

The known device has a disadvantage - the low quality of cleaning root crops from soil.

The technical result achieved when using the utility model is to improve the quality of cleaning root crops from soil.

The specified technical result is achieved by the fact that the rollers are made in the form of spirals. The ends of the spirals are rigidly fixed on bushings, which are installed symmetrically inside the frame from different sides. A variator is installed on the drive shaft. The direction of winding of odd and even rollers is performed in opposite directions.

FIG. 1 shows a general view of the cleaner, and FIG. 2 - the same, side view.

The soil cleaner for root crops includes rollers 2 mounted on the frame 1 with the possibility of rotation and made in the form of spirals. The ends of the spirals of the rollers 2 are rigidly fixed on the bushings 3, which are installed symmetrically inside the frame on different sides. On one side of the rollers 2, the bushings 3 are coaxially mounted on the shafts 4. The shafts 4 are interconnected by sprockets 5 through a chain 6, and the sprockets of the even and odd rollers 2 are installed outside the frame 1 from different sides with the possibility of rotation of the even and odd rollers with different frequencies from drive shaft 7. To ensure the possibility of rotation of the sprockets of even and odd rollers 2 with different frequencies, at opposite ends of the drive shaft 7 sprockets 8 and 9 with a different number of teeth are installed. A variator 10 is installed on the drive shaft 7. In addition, the winding of the spirals of the odd and even rollers 2 is made in opposite directions.

The soil cleaner for root crops works as follows. The drive is turned on (not shown in the figure), which, through the variator 10 and the drive shaft 7, transmits the torque to the sprockets 8 and 9, which, in turn, drive the sprockets 5, installed on opposite sides of the frame 1, at different frequencies. From sprockets 5 through shafts 4 and bushings 3, rotation is transmitted to rollers 2, made in the form of spirals, the ends of which are rigidly fixed on bushings 3. Then, root crops uncleaned from the soil are fed to rollers 2. Interacting with the rotating surface of rollers 2, the root crops move in the direction of them rotation. When moving, the roots come into contact with the even and odd rollers 2, rotating at different frequencies, as a result, simultaneously with the translational, the roots receive a rotational movement with sliding along the surface of the rollers. Since the direction of winding of odd and even rollers is made in opposite directions, then additionally root crops, when rotating and moving forward, are displaced on each adjacent roller 2 to the left or to the right, depending on the direction of spiral winding. This increases the turnover of root crops around its axis and, accordingly, the area of their contact with the surface of the rollers 2, thereby improving the process of separating the soil from the root crops. The soil separated from the root crops is removed into the gaps between the rollers 2, as well as between the spiral turns. With a lesser degree of contamination of root crops using the variator 10, the rotational speed of the drive shaft 7 is increased, as a result, the throughput of the device increases without deteriorating the quality of cleaning the root crops. And, conversely, with an increase in the degree of contamination of root crops using the variator 10, the rotational speed of the drive shaft 7 is reduced, as a result, the throughput of the device increases without deteriorating the quality of cleaning the root crops.

Consequently, the execution of the rollers in the form of spirals, the ends of which are rigidly fixed on bushings installed symmetrically inside the frame from different sides, installation on the drive shaft of the variator, as well as the execution of the direction of winding odd and even rollers in opposite directions increases the quality of cleaning root crops from soil.
