Description

The invention relates to the field of agricultural engineering. The purpose of the invention is to improve the performance of the device. The device contains a bar rotating drum having the shape of two truncated cones facing small bases towards each other. The front ring 3 is fixed on the shaft 11 by means of inclined spokes 5, having an oval shape in cross section and provided with sharpening in the work zone. The rods 2 of the rear cone are fixed to the rear ring 8 of the console, have curved free ends and are inclined to form a cone as and. rods 1. The front ring 3 is equipped with curved knives 4. When the device is in operation, the rotating drum digs up the formation and separates impurities.

The invention relates to the field of agricultural engineering, in particular to a device for digging of roots and vegetables used in harvesting machines.

The purpose of the invention is to improve the performance and operation of the device.

In Fig.1 schematically shows a device for digging of the root-club, ·, θ neplod, side view; figure 2 is the same, front view; on fig.Z - the same, section aa in figure 2; in fig. 4 is a section BB in FIG.

The device for digging up the root, 15 tubers, is made in the form of two truncated cones, facing vertices inward, consisting of rods 1 and 2, a front ring 3 with curvilinear knives 4, knitting needles 5 tilted by 20 angles to the axis of rotation and rigidly fixed to the hub 6 of the rear ring 7 and 8, elastic wedge-shaped scraper 9, connecting strips MOT, drive shaft 11, support rollers 12, conveyor 13, guide of the rubberized bar grate 14 of the pitched tray.

The rods 1, which form the working, transporting and separating surface of the drum, are covered with an elastic material and are set at an angle e to the surface of the front ring.

3. Between adjacent bars 1 along the perimeter of the drum, elastic wedge-shaped scrapers 9 are fixed, located with a slope in the direction of rotation to the mass outlet.

The bars 2 of the second drum are mounted console, and on the mass output side are curved and mounted at an angle H to the rear ring 8.

Adjusting the depth of undermining is carried out by changing the position of the rotary body 15 on the frame 16 using the mechanism 17 and the lifting height of the suspension 18 and the rack 19 in the front of the body 15.

The device is driven by a gearbox 20 through the shaft 11, to which, using the hub 6 and the spokes 5, the front ring 3 is rigidly fixed. The spokes 5 in cross section have an oval shape.

The device works as follows.

During the forward movement of the unit, the device rotates and hits

in the soil with curvilinear knives 4 and delivers the mass into the inside of the drum. Initially, the formation is divided by the oval side of the spokes 5 into parts and, using elastic wedge-shaped scrapers 9, rises at a certain angle with the formation shifted to the exit, and then slides downwardly, drops from the scraper 9, rotates and falls along a certain trajectory (FIG ,four). The rise and fall of the mass with the root crops occurs until it falls to the back ring 7 of the first drum, where the main part of the soil is sifted through the rods of the drum. Then the cannon rods of the second drum root crops and the remaining soil rise to a certain angle, where the root crops are rolled to unload to the opposite end of the drum, falling on the rubber bar 14.

Claims (4)

Claim 1. A device for digging out root crops, including having a frustoconical shape with a horizontal axis of rotation from the drive shaft, a drum made of front and rear rings connected by rods, while the front ring ₃₅ o, having a larger diameter than the rear one, is arranged along curved knives tilted to the horizontal with its perimeter, and inclined scrapers are installed on the inner surface of the drum, the device is equipped with a sloping tray installed in its rear zone, characterized by so that, in order to improve the performance of the device 45, the front ring is mounted on the drive shaft by means of the spokes bent towards it, and the back ring is provided with rods fixed to it, forming a drum in the form of a 50 truncated cone, facing the small base to the small base of the front drum, the rods of which are covered with elastic material and set obliquely to the forming of the latter, 55 while the front drum scrapers placed between its adjacent bars, are wedge-shaped and elastic, and the pitched tray is made in the form of a lattice. four 3 2. The device according to claim 1, from l and * by the fact that, in order to increase the efficiency of separation of the excavated reservoir, the edges of the spokes of the front ring, facing the direction of rotation, have been sharpened from the inside of the drum and are made in the area of their working part with transverse section in the form of an oval. 1366092 3. The device according to claim 1, characterized in that the bars of the rear drum are made console, _g tilted to the generators of this baraba □ on, and their cantilever ends are curved. 4. The device according to claim 1, characterized in that the grid of the pitched tray is rubberized. · FIG. 2 Aa B- 6 fi & .З
