Description

FIG. one

The invention relates to agricultural machinery engineering, in particular to screw impurity root rollers used in self-propelled root-harvesting machines.

The purpose of the invention is to increase the cleaning efficiency of root crops and eliminate sticking of the drum with the soil.

FIG. 1 schematically shows a screw roller cleaner for removing root crops from impurities; a plan; in fig. 2 | in FIG. one.

It is necessary to test resistance by turning, thanks to which the springs 12 begin to twist at a certain angle. For some periods of time, the angular velocities of the hollow cylinder I and the coiled winding 4 become unequal. In this connection, there is a relative movement of the coiled winding 4 along the surface of the hollow cylinder 1, i.e. it is ensured that it is cleared of adhering soil.

section A-AO Root beet crops located on the drum are said to have a relative speed, i.e.

1 A screw drum consists of hollow angular velocities from cylinder 1 of cylinder I, at the ends of which the clamping and winding 4 are provided by their intense drive gear 2 and support 3 turnings around their own axes of the blade. On the hollow cylinder 1 freely (curtailment. This achieves a better clearance clearance) put on the screw coil 4, on the lateral surfaces of the adhering wadding along its entire length. On the trunks of the soil.

On the pins 2 and 3 of the fixed direction, thanks to which the flanges are fixed 9 and 10 by means of pressing on the surface of the roll of the corniceples P. At the same time, between the disks 5 of the beet fruit, additional 6 are connected and flanges 10 are installed spring accelerations, which also contribute to

there are 12 twists, the ends of which are hard, intense turns and the best

The spring 12, mounted on the drive axle 2, has a greater rigidity compared with another spring 12, wherein the screw winding 4 is made elastic.

The screw drum is operated as follows.

The drive pin 2 receives rotation (in the direction of co), whereby the hollow cylinder 1 rotates at a predetermined angular

In this position (i.e. for these periods of time The screw winding 4 and the hollow cylinder 1 rotate at the same angular velocity, which is equivalent to their rigid connection. After overcoming such resistance.

Since the plates 16, overlapping the ends of the arcuate grooves 15, are attached to

disks 5 and 6 by means of bolts 17

mi Due to the fact that on the disk 5 .. then using the plates 16 of different pin-joints using screw mechanisms, it is possible to limit the angles of rotation of the disks 5 and 6 on the pins 2 and 3. This adjustment should be made on the basis of specific cleaning conditions . For example, with insufficient cleaning

1UI coiling 4 also receives rotation, 50 beet root crops from adhering soil because it is rigidly fixed, it is necessary to increase the dimensions of the arc-shaped grooves 15, i.e., apply narrower plates 16 or remove them altogether. Apply the spring 12 torsion, connect-, ... -Nuch disk 5 and the flange 10, more

In the axle 2 in the support 7 slides (bolts) 8, the end of the screw winding 4, the latter also rotates together with the hollow cylinder 1 with the same angular velocity. At the same time, the second end of the screw-screw mechanisms (bolts) 8 on the disk 6, seated on the bearing pin 3 in the sliding bearing 7, is connected to the pin 3 by means of the second spring 12

In this position (i.e. for these periods of time) The screw coil 4 and the hollow cylinder 1 rotate at the same angular velocity, which is equivalent to their rigid connection.
