Description

The invention relates to agricultural engineering, in particular to machines for planting potatoes.

Known section of the seeder for group sowing of seeds, connected to the frame of the seeder through a four-link articulated-lever system. The section includes a housing with a seed box, a sowing machine, a coulter. It is connected by a link to the body. The section also has a harrow, a roller and a train. The sowing apparatus is made in the form of an endless tape provided with cells. It is placed on different-sized driving and driven drums. The drive drum is aligned with the drive shaft by means of a chain drive from the seed drill support wheels. The driving drum is mounted above and in front of the driven drum. A seed reflector in the form of a loop made of rubberized material is mounted above the driving drum. The width of the reflector loop is equal to the width of the endless tape. The sowing section will provide a compact placement of 3-4 seeds in one nest with uniform removal from the seed box. (RU No. 2280348 C2, published on 27.07.2006).

The disadvantage of this section is the lack of fertilizer application along with the seeds.

Known section of the seeder design Burkova LN, which contains a hopper for seeds and fertilizers, sowing machines for them and seed fertilizer disc coulters. A transfer box is installed under the sowing units. It consists of two parts. One part is connected with the fertilizer seed pipeline for sowing fertilizers, the other - with the fertilizer seed pipeline for sowing seeds. Coulter discs are made of different diameters. The fertilizer coulter disc is made with a diameter greater than the diameter of the seed coulter disc. The first one is installed in front in one longitudinal-vertical plane. A leveling bar is installed between them. The beam has tides opposite each coulter. The tides have triangular bevels from their middle to the edges. The invention will improve the nutritional conditions of seeds and increase their germination. (RU No. 2256315 C2, published on 20.07.2005).

The disadvantage of this section is the lack of metered supply of the hydrogel.

Known potato planter SAYA-4 (Halansky V.M., Gorbachev I.V. Agricultural machines. - M .: KolosS, 2003. - 624 p.: ill. - (Textbooks and teaching aids for students of higher educational institutions)) . It contains a bunker equipped with a belt conveyor for supplying tubers to the feed bucket. The conveyor turns on automatically, depending on the presence of tubers in the feed bucket. The planting device is an endless bush-roller chain with open-type spoons, driven by the tractor's power take-off shaft (PTO).

The disadvantage of this section of the potato planter is the lack of metered supply of hydrogel in a separate ridge.

The closest technical solution to the claimed invention in terms of the totality of features is the section of the SN-4B potato planter, which includes a potato hopper, a scooping apparatus, which is a disk equipped with twelve spoons that capture tubers, operates from a PTO through a gearbox, the section is equipped with a fertilizer seeding apparatus for fertilization, furrow-forming discs go ahead of the section, there is a tuber duct, a fertilizer duct, an auger located in the feed bucket, a tedder, copying and supporting wheels in the section. (Khalansky V.M., Gorbachev I.V. Agricultural machines. - M .: KolosS, 2003. - 624 p.: ill. - (Textbooks and teaching aids for students of higher educational institutions)).

The disadvantage of this section of the potato planter is the lack of metered introduction of the hydrogel into a ridge separate from the tubers, with its embedding in the transverse direction opposite the potato tubers.

The essence of the invention is as follows.

The objective of the claimed invention is to eliminate these disadvantages.

EFFECT: increased productivity of potatoes in arid areas by dosed application of hydrogel into a ridge separate from the tubers, with its embedding in the transverse direction opposite the potato tubers.

The specified technical result is achieved by the fact that the potato planter section containing a hopper for potato tubers, a scooping apparatus, which is a disk with twelve spoons, a fertilizer spreader, a fertilizer duct, a guiding wheel and a coulter according to the invention, inside the coulter there is a rotor, two-arm levers connected to movable plates, on section, a hydrogel hopper is installed at the bottom of which there is a dosing device made in the form of an auger operating from a scooping apparatus, under the dosing device there is a storage chamber at the bottom of which there is an active ejector controlled by a retractor connected via a relay to a piezoelectric sensor installed inside the opener at the end of the rod with a spring with a limit switch, which is installed with the possibility of its movement along the rod to act on the piezoelectric sensor at the moment of opening the movable plates when the rotor passes through them, and the active ejector is connected to the movable working body located in the lower part of the section.

The invention is illustrated by drawings.

In FIG. 7 is an electric circuit for controlling an active ejector.

In FIG. 8 shows the location of the hydrogel and potato tubers in the ridge.

The section of the potato planter contains a hopper for potato tubers 1, a scooping apparatus 2, which is a disk with twelve spoons, a fertilizer spreader 3, a fertilizer duct 4, a copying wheel 5, a coulter 6. Inside the coulter there is a rotor 7, two-arm levers 8 connected to movable plates 9.

A hydrogel hopper 10 is installed on the section, at the bottom of which there is a dosing device 11 made in the form of an auger operating from a scooping apparatus. Under the dosing device 11 there is a storage chamber 12, at the bottom of which there is an active ejector 13 controlled by a retractor 14 connected through a relay 15 to a piezoelectric sensor 16.

The piezoelectric sensor 16 is located inside the coulter 6 at the end of the rod 17 with a spring 18 with a limit switch 19, which is installed with the possibility of moving along the rod 17 to act on the piezoelectric sensor 16 at the moment of opening the movable plates 9 when the rotor 7 passes through them. Retractor 14 , relay 15 and piezoelectric sensor 16 are connected according to the diagram in FIG. 7, and the active ejector 13 is connected to the movable working body 20 located in the lower part of the section.

Examples of specific implementation.

The movable working body 20 of the section is set to a predetermined depth, fixing it relative to the active ejector 13 in one of several positions, after which the hopper for potato tubers 1 and the hopper for hydrogel 10 are filled. located in the coulter 6. When the rotor 7 passes through the movable plates 9, they open, the limit switch 19 moves along the rod 17, followed by the impact on the piezoelectric sensor 16 and it is triggered. In this case, the circuit is closed, and the current from the tractor network enters the relay 15 and the retractor 14 is triggered, opening the active ejector 13 located at the bottom of the storage chamber 12, which in turn already has a portion of the hydrogel that got there by moving the dosing device 11 in in the form of an auger and a hydrogel, enters the ridge made by the movable working body 20 to a predetermined depth. During the passage of the rotor through the movable plates 9, the potato tuber is ejected under the action of gravity into the ridge made by the coulter 6. Due to the simultaneous operation of the retractor 14, which provides a dose of hydrogel to the movable working body 20 and the ejection of the potato tuber by the rotor 7 into the ridge made by the coulter 6, the hydrogel is embedded in the transverse direction opposite the potato tubers.

Thus, the potato planter section makes it possible to increase the yield of potatoes in arid areas by dosed application of the hydrogel into a ridge separate from the tubers, with its embedding in the transverse direction opposite the potato tubers.
