RU188046U1 - ROOT CLEANER FOR SOIL - Google Patents

Abstract

The utility model relates to agricultural machinery, in particular, to root crops from the soil.

The root crop cleaner from the soil contains cylindrical rollers mounted on the frame with the possibility of rotation in one direction. Rollers are interconnected by asterisks. Asterisks of even and odd rollers are installed outside the frame from different sides with the possibility of rotation of even and odd rollers with different frequencies. The surfaces of even and odd rollers are made of materials with different coefficients of friction. Odd rollers are shafts on which a cylindrical housing is eccentrically mounted.

The use of this cleaner allows you to improve the quality of cleaning root crops from the soil.

Description

The utility model relates to agricultural machinery, in particular, to root crops from the soil.

Known roller screw cleaner of potato tubers from the soil (Aut. St. SU No. 1306508, Publ. 30.04.87, Bull. No. 16), containing a cylindrical body fixed to the shaft with a screw winding covering it, characterized in that, in order to reduce damage of tubers, a sleeve is fixed to the body with flat blades evenly spaced around its circumference, forming cavities isolated from each other, and screw winding is installed with an interference fit at the ends of these blades. The rollers are made to rotate in one direction by means of interconnected sprockets.

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

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

The specified technical result is achieved by the fact that the sprockets of even and odd rollers are installed outside the frame from different sides with the possibility of rotation of the even and odd rollers with different frequencies. The surfaces of even and odd rollers are made of materials with different coefficients of friction. The odd rollers are made in the form of shafts on which a cylindrical housing is eccentrically mounted.

In FIG. 1 shows a general view of the cleaner, and FIG. 2 is the same, section view AA.

The root crop cleaner from the soil includes cylindrical rollers 2 and 3 mounted on the frame 1 with the possibility of rotation, and on the odd rollers 2 made in the form of shafts on which a cylindrical body is eccentrically mounted. Rollers 2 and 3 are interconnected by sprockets 4 through chain 5, and sprockets of odd rollers 2 and even rollers 3 are mounted outside the frame 1 from different sides with the possibility of rotation of even and odd rollers with different frequencies from drive 6. To enable rotation of even sprockets and odd rollers with different frequencies, the drive 6 is equipped with a shaft 7 with sprockets 8 and 9 mounted at its opposite ends with a different number of teeth. The surfaces of the odd 2 and even rollers 3 are made of materials with different coefficients of friction.

Cleaner root crops from the soil works as follows. The drive 6 is turned on, which transmits torque through the shaft 7 to the sprockets 8 and 9, which, in turn, drive the sprockets 4 into rotation on even 3 and odd rollers 2 with different frequencies. Then, root crops, untreated from the soil, are fed to the rollers. Interacting with the rotating surface of rollers 2 and 3, root crops progressively move in the direction of rotation of the rollers. Moving along the rollers of the root crops, they are in contact with the even rollers 3 and the odd rollers 2, which contain a cylindrical body eccentrically mounted on the shaft, and rotating at different frequencies, which creates the conditions for the surface of the rollers to slip on the root crops and at the same time shaking the root crops and pollution particles. Different coefficients of friction of the surfaces of even and odd rollers allow more efficient cleaning of root crops from soil, which is removed into the gaps between rollers 2 and 3. The cleaned root crops, depending on the degree of contamination and purpose, are subsequently transferred from the cleaner to either the sink or to further sorting and processing .

The placement of stars of even and odd rollers outside the frame 1 from different sides with the possibility of rotation of the even and odd rollers with different frequencies in conjunction with an eccentrically mounted odd rollers 2 on the cylindrical body, as well as various friction coefficients of the surfaces of the even and odd rollers, allow to increase the turnover of root crops around its axis when they move on rollers 2 and 3 with simultaneous shaking.

This increases the contact surface of the product to be cleaned with the surface of the rollers, as well as the intensity of separation of contaminant particles from root crops, thereby improving the quality of cleaning root crops from soil.
