Abstract

The invention relates to devices used in the harvesting of beet root crops, and can be used in root-extracting working bodies of self-propelled soil harvesting machines. The goal is to reduce injury to the roots. The root intake pad consists of a bar disc mounted on an axis by means of a hub on which brackets are installed, on the latter by means of bolts L-shaped paws 6 are fixed, the ends of which are made in the form of rotary trapezoidal plates 7. The upper bases of the plates are freely mounted on the axis x 8 which are located in the planes of the discs 1. The plates 7 and the ends of the paws 6 are connected by torsion springs 9 mounted on the axles 8 and providing the springing of the plates 7 to the inside of the discs. Limiters 10 are fixed at the ends of the paws 6, and the planes of the plates 7, facing the inside of the discs, are made with grooved grooves 11. Two rod discs mounted at an angle to the axes on the axes rotate and move along a row of beet roots that are extracted from the soil. Fork-type digging tool. Disc plates

The invention relates to agricultural machinery, in particular to devices used in the harvesting of beet root crops, can be used in the root-extracting working bodies of self-propelled root harvesters and is an improvement of the invention in accordance with the authors. Ns 923421,

The goal is to reduce injury to the roots.

FIG. Figure 1 shows a single disk of a cortex; Side view; figure 2 - capture; on fig.Z - section aa in figure 2.

The Kornozabornik contains a bar disk 1 mounted on axis 2 by means of hub 3. Brackets 4 are installed on the hub, on which bar bolts 5 secured L-shaped bar legs 6, the ends of which are made in the form of rotary trapezoidal plates 7. The upper bases of the plates are freely mounted on OS x 8, which are located in the planes of the disks 1.

The plates 7 and the ends of the legs b are connected by torsion springs 9 mounted on the axles 8 and providing springing of the plates 7 to the inside of the discs 1. At the ends of the paws 6, the stops 10 of the plates 7 are fixed, and the planes of the plates 7 facing the inside of the discs 1 are made with grooved recesses eleven.

Root intake works as follows.

Installed at an angle to one another on the axis x 2, the two rod disks 1 rotate in an arrow about and move along a row of beet root crops, which are removed from the soil by a forked-type digging tool. The ends of the L-shaped legs move in the surface layer of the soil and the plates 7 of two disks 1, grip and clamp the heads of the root crops with internal grooves with grooved notches.

11. Because of this, the contact between the heads of the beet roots and the plates 7 is superficial, the contact area is significantly increased and sufficient frictional force is created to ensure the extraction of the beet roots from the soil without trauma from the side surfaces. The rotation of the plates 7 on the wasps x 8 and their springing into the disks 1 by means of torsion springs 9 ensures that both small and large-sized beet roots are gripped and clamped.

At the same time, the contact and interaction of the plates 7 and the side surfaces of the beet root crops is also softened. Due to the fact that when beet is picked up and extracted from the soil of the root crops, considerable effort is made of the grooved recesses 11, which create a significant contact area, self-purify from the soil falling inside the recesses 11. The flat plates 7, when moving in the surface soil layer, do not affect beef resistance of the rootbush. The limiters 10 rotations allow the plates 7 to not extend beyond the planes of the disks 1 and have a maximum approximation inside the disks 1 that do not contribute to damage to the roots.

Claims (2)

1. Kornnezabornik on avt, sv. No. 923421, characterized in that. in order to reduce injuries to the roots, the grips are made in the form of trapezoidal plates, the upper bases of which are connected to the legs with the possibility of rotation inside the discs, while recesses are made on the inner Planes of the plates. 2. A root intake pickup according to claim 1, wherein the trapezoidal plates are mounted on the bars with their upper bases by means of axles and are connected with them by means of torsion springs.
