Description

Description of the invention

The invention relates to the field of agricultural engineering and can be used for 2 planting potatoes.

A well-known potato planter, which contains a frame on which a hopper with feeding buckets for potato tubers, containers for fertilizers, draining and fat seeding devices, fat pipes, coulters and disc wrappers are mounted (see Kozachenko B.O., Kononuchenko V.V. Mechanization of potato production Handbook. - K.: Urozhai, 1991. - P. 60-64).

A significant disadvantage of such potato planters is the supply of fertilizers during planting potatoes in the furrow with a continuous 70 tape, which leads to their overspending.

The closest in technical essence to the proposed one is a potato planter (see AS USSR Mo 974954, class A 01 C 9/04, 1982), which contains a frame mounted on support wheels, on which a hopper with feeding buckets for tubers is mounted potatoes, containers for fertilizers, exhausting devices, fat pipes, tuber pipes and coulters. 19 The disadvantage of such a potato planter is that the portion of fertilizer that is introduced into the furrow is stretched. in the feed line, as a result of the forward movement of the machine, it is sown not only in the place of planting potato tubers, but also spread along the furrow, which leads to unproductive consumption of the part of fertilizers that fall outside the place of planting potato tubers. This leads to insufficiently efficient use of fertilizers and, accordingly, causes deterioration of root nutrition of potato plants.

The invention is based on the task: in the potato planter by changing its design, to obtain a new technical result, which consists in providing a portioned supply of fertilizers to the place of planting tubers, which will improve the root nutrition of potato plants and make it possible to use fertilizers more rationally and efficiently, as a result of which the yield of potatoes will increase.

The task is solved as follows: in a potato planter, which consists of a frame mounted on 29 supporting wheels, on which a bunker with feeding buckets for potato tubers, containers for fertilizers, "exhausting devices, fat pipes, tuber pipes, coulters are mounted; distribution cones are installed under the outlet openings of the fat pipes, which are kinematically connected to the levers by rods, while the levers are spring-loaded relative to the bulb pipes.

The following drawings show: Fig. 1 - potato planter, side view; in Fig. 2 - a device for multi-portion application of fertilizers with a closed output opening of the fat pipe; Fig. 3 shows a device for portioned fertilizer application with an open outlet of the fat pipe.

The potato planter consists of a frame 1, on which a hopper 2 with feeding buckets З for potato tubers, support 4 and running wheels 5, fertilizer containers 6, sowing discs 7 and fat pipes 8 are mounted, under the outlet holes of which distribution cones 9 are installed , which are kinematically connected by rods 10 to levers 11.

Under the exhausting devices 12, tuber pipes 13 are installed, through which the tubers enter the furrows formed by coulters 14. The levers 11 are spring-loaded relative to the tuber pipes 13 by springs 15. Disc wrappers 16 are placed behind the tuber pipes 13.

The potato planter works as follows. During the movement of the potato planter, the torque from the cardan "F" transmission of the tractor is transmitted to the exhausting devices 12. The latter, rotating, grab the potato tubers Z from the feeding buckets Z and feed them into the tuber pipes 13. At the same time, the fertilizers that are in the containers b are sown by seed discs 7 into fat pipes 8. The lower opening of fat pipe 8 is closed

With" distribution cone 9. Moving along the tube 13, the potato hits the lever 11, which falls down under the weight of the potato. At the same time, with the help of rods 10, the distribution cone 9 is lowered, opening the output hole of the fat pipe 8. A portion of fertilizers, hitting the distribution cone 9, is scattered 49 in a circle and falls to the bottom of the furrow formed by the coulter 14, in the center of which the potato tuber falls. After the potato ceases to interact with the lever 11 and falls into the furrow, the distribution cone 9 due to the action of av | spring 15 returns to its initial position and covers the output opening of the fat pipe 8. In this way, portioned supply of fertilizers to the place of planting of potato tubers occurs. The disc wrapper 16 covers the tubers around the potatoes with a layer of soil. -I 20 Using a potato planter will make it possible to use fertilizers more rationally and efficiently, "as a result of which the root nutrition of potato plants will improve, which will lead to an increase in its yield.

Claims (1)

The formula of the invention is in the Potato planter, which contains a frame mounted on supporting wheels, on which a hopper with feeding buckets for potato tubers, containers for fertilizers, exhausting devices, fattening pipes, tuber pipes, openers is mounted, which is distinguished by the fact that distribution cones are installed under the output holes of the fattening pipes, which are kinematically connected by rods with levers, while the levers are spring-loaded relative to 60 bulb conduits. b5
