RU200456U1 - ROOT CLEANER FROM SOIL - Google Patents

Abstract

The utility model relates to agricultural engineering, in particular, to the soil remover for root crops. The root crop cleaner contains rollers mounted on a frame with the possibility of rotation in one direction and 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 rollers are made in the form of spirals. The winding direction of spirals of odd and even rollers is made in opposite directions. On the frame under the rollers and along them there are brushes in contact with the rollers, the length of which is equal to the length of the rollers. The quality of cleaning root crops from soil is increased.

Description

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

Known cleaner for soil from root crops [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 - 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, and the direction of winding the spirals of odd and even rollers is performed in opposite directions. On the frame under the rollers and along them, brushes in contact with the rollers are installed. The length of the brushes is taken to be equal to the length of the rollers.

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. Rolls 2 are rigidly mounted on bushings 3, coaxially mounted on shafts 4. Shaft 4 are interconnected by sprockets 5 through chain 6, and sprockets of even and odd rolls 2 are installed outside the frame 1 from different sides with the possibility of rotation of even and odd rolls with different frequencies from the drive 7. To ensure the possibility of rotation of the sprockets of the even and odd rollers with different frequencies, the drive 7 is equipped with a shaft 8 with sprockets 9 and 10 installed at its opposite ends with a different number of teeth. Winding spirals of odd and even rollers 2 is made in opposite directions. On the frame 1 under the rollers 2 and along them there are brushes 11 in contact with the rollers 2. The length of the brushes 11 is equal to the length of the rollers 2.

The soil cleaner for root crops works as follows. The drive 7 is turned on, which, through the shaft 8, transmits the torque to the sprockets 9 and 10, which, in turn, drive the sprockets 5 into rotation on the even and odd rollers 2, respectively, with different frequencies. Then the root crops, uncleaned from the soil, are fed onto the rollers 2, made in the form of spirals. Interacting with the rotating surface of the rollers 2, the roots move in the direction of rotation of the rollers. 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, they receive a rotational motion with the presence of slipping along the surface of the rollers. Since the direction of winding the spirals of the odd and even rollers is made in opposite directions, then additionally the root crops, during their rotation and forward movement, 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 their both vertical and horizontal axes 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. Installed on the frame 1 under the rollers 2 along them and in contact with them brushes 11, the length of which is equal to the length of the rollers, clean off the dirt adhering to them from the entire surface of the spiral of each of the rollers 2, maintaining the initial state of the surface of the spirals.

Consequently, the execution of the rollers in the form of spirals with the direction of winding the spirals of odd and even rollers in opposite directions, as well as the installation of brushes in contact with them on the frame under the rollers and along them, the length of which is equal to the length of the rollers, improves the quality of cleaning root crops from soil.
