Description

one

The invention relates to the field of agricultural engineering, in particular, to machines for the selection and loading of sugar beet roots and other root crops.

A beet harvesting machine is known, comprising a root extracting device, a series of transversely located auger rollers, a cleaner and an unloading conveyor. The auger rollers transport the roots to the middle of the machine. Mounted above the ends of the rollers, the screen resets the beets to the lower chain conveyor. 1.15

The disadvantage of the machine is inadequate cleaning of root crops from impurities due to the insufficient transport capacity of the rollers.

Also known are agricultural machinery 20 for a machine for picking and loading root crops, comprising a feeder, a receiving part, a series of transversely arranged worm rollers, a shaft with blades, a screw cleaner, and a discharge conveyor.

This device is closest to the invention in its technical essence and the achieved result 2 .30

Its disadvantage is the braking of a pile of roots in the final part of a series of transversely located rollers at the protective shield of the auger cleaner, which reduces the productivity of the machine and deteriorates the quality of cleaning the roots due to insufficiently uniform loading.

The purpose of the invention is to increase the productivity of ore and the quality of cleaning of root crops from impurities by changing the direction of movement of the root crops and feeding them to the auger cleaner.

This is achieved by installing a device made of an arcuate screen, the convex side of which is attached to the cleaner) and a disk divider behind it fixed at the end of the screw roller and having protrusions on its working surface.

FIG. 1 shows a structural diagram of the machine, side view; Figure 2 shows a plan view; in fig. 3 is a view A of FIG. 2

The machine for the selection and loading of root crops consists of a main frame 1 on which workers are mounted and a power plant 2 is installed, a drive axle -3 and steering wheels 4. On a movable frame 5 hinged to a drive axle 3, there is a feeder 6 and a receiving part consisting of a shaft 7 with multi-faceted discs, auger shafts 8, counter-rotating rollers 9 and 10, and a longitudinal conveyor 11.

A cleaning device 12 is mounted thereto, including a series of transversely arranged screw rollers 13, a shaft with blades 14, and a screw cleaner 15.

A device is installed above the end portions of the screw rollers 13 to change the direction of movement of the root crops and feed them to the screw cleaner 15, made of an arcuate screen 16, with the convex side facing the cleaner, and the agitator 17 located behind it, attached to the end of the screw roller 13 to having on its working surface protrusions

The screw cleaner 15 consists of a series of pairs of opposing rotating shafts 18.

On the side of the machine is installed the discharge conveyor 19,

As the power plant 2 uses a tractor with off wheels, designed to drive the working bodies and the movement of the machine,

The machine for picking and loading the roots is working as follows.

When the machine is moving along the submersible shaft, the feeder b captures 1-1 feeds the roots to the screw shafts 8 of the receiving part. Screw shafts 8 due to the counter winding cm pi; -k ;: root crops to the center and supply it to a longitudinal conveyor 11, then a pile of root crops goes to a number of transversely located screw rollers 13 and the shaft with blades 14, while the pile of root crops is reported : 5rem. Lateral and longitudinal movement to the screw cleaner 15. Lateral movement of a pile of roots on

screw cleaner 15 contributes to the arcuate screen 16, installed in front of the protective shield of the Schnekov cleaner and above the end parts of the screw rollers 13 and the agitator 17 located behind it, which has an active working surface made in the form of protrusions. Due to this, a pile of roots does not slow down, does not form piles and evenly load the screw cleaner 15 in height, while ensuring high quality of cleaning and contributing to an increase in the productivity of the machine. The disk 17 provides additional tedding of the root crop stream and their cleaning.

Purified roots are fed to the discharge conveyor 19 and then to the vehicles
