The technical problem, the solution of which is directed to the useful model, is the improvement of the arrangement of the seed pipe and the discs of the disk working organs of the potato planting unit so that the distance between the outlet of the seed pipe and the furrow coulter, as well as the distance between the seed pipe and the disks of the disk working organs have a minimum value. with

The technical result, which is achieved by solving the given technical problem and using the improved potato planting unit, is a significant increase in the distance between the steering wheel handles and the disks - disk working bodies horizontally, that is, an increase in the space for the operator's feet, which significantly increases the safety of the operator's work while driving potato planting unit.

The task is solved, and the technical result is achieved by the fact that in the potato planting unit, which contains a frame, an engine, a gearbox, the drive is kinematically connected through a gearbox to the engine, a steering wheel and a clutch, fixed on the frame behind the drive, on which the coulter is mounted a furrow for forming a furrow, a seed tube for planting potato tubers in a furrow and disk working bodies with discs for rolling up potato tubers planted in a furrow, according to a useful model, the output pipe of the seed tube is inserted inside the coulter-furrow and rigidly fixed in the latter, and the discs of disk workers organs are located directly behind the furrow. c" The given features characterizing the useful model are essential, as they are sufficient in total to ensure the efficiency and solution of the technical problem, and each separately is necessary for the identification and distinctiveness of the claimed potato planting unit from similar technical solutions known in the art. di This set of general and distinctive features from the prototype, which characterizes the improved potato planting unit, is new and sufficient in all cases to which the scope of legal protection extends, as it solves the technical problem. - The cause-and-effect relationship between the new set of essential features of the improved potato planting unit and the achieved technical result is as follows.

Due to the fact that the outlet pipe of the seed pipe is inserted inside the furrow coulter and rigidly fixed in the latter, and the discs of the disk working bodies are located directly behind the furrow coulter, their compact arrangement in relation to the furrow coulter is ensured.

With this arrangement, the distance between the outlet pipe of the seed pipe and the furrow coulter, as well as the distance between the seed pipe and the discs of the disk working organs have a minimum value. с As a result, the horizontal distance between the steering wheel handles and the disks of the disc working bodies increases significantly, that is, the space for the operator's feet increases.

Due to this, the safety of the operator when operating the potato planting unit is significantly increased. Because the improved potato planting unit has other distinctive features that complement and characterize the useful model in certain cases of its implementation and are used to achieve additional technical results.

In the potato planting unit, according to the useful model, the seed pipe is made in the form of a telescopically connected vertical funnel, a bent inlet nozzle and an inclined outlet nozzle, 62 made with a bevel from the bottom of the outlet end.

This implementation of the seed pipe additionally ensures the manufacturability of its design, assembly and fastening of the inclined outlet pipe on the coulter-furrow using, for example, a welded connection.

And the presence of a bevel from the bottom of the outlet end prevents the outlet pipe from being clogged with soil.

From the state of the art, the applicants did not find technical solutions that correspond to the general and distinctive features of the potato planting unit, which is claimed, which indicates that the proposed technical solution is not part of the state of the art and meets the utility model criterion of "novelty".

In the future, the useful model is explained by a detailed description of the preferred version of execution and operation with references to the attached drawing, which shows the general view of the potato planting unit. 70 The potato seeding unit includes frame 1, engine 2, gearbox C, drive 4 is kinematically connected through gearbox C to engine 2, steering wheel 5 and clutch 6, fixed on frame 1 behind drive 4, on which a coulter-furrow 7 is mounted for forming a furrow , seed tube 8 for planting potato tubers in the furrow and disc working bodies 9 with discs 9a for rolling up the potato tubers planted in the furrow.

The peculiarity of the potato planting unit is that the outlet pipe 8 of the seed duct 8 is inserted /5 inside the opener-furrow 7 and rigidly fixed in the latter, and the discs Behind the disc working bodies 9 are located directly behind the opener-furrow 7.

In order to increase the manufacturability of the construction of the assembly and fastening of the inclined outlet pipe, the seed pipe 8 is made in the form of a telescopically connected vertical funnel 8a, a bent inlet pipe 86 and an inclined outlet pipe 8b, made with a bevel 8g from the bottom of the outlet end 8d.

The outlet pipe 8 of the seed pipe 8 can be rigidly fixed in the coulter-furrow 7 by means of a welded connection.

The seed tube 8 is made in the form of a telescopically interconnected vertical funnel 8a, a bent t inlet pipe 86 and an inclined outlet pipe 8c, made with a bevel 8g of the outlet end 8d.

The potato planter works like this.

When the engine 2 is turned on, the potato planting unit, controlled by the operator, moves forward for b with the help of pushers 4, made in the form of support wheels with ground hooks.

At the same time, the furrow coulter 7 forms a furrow. co

With the help of the operator or his assistant or from the accumulator hopper (not shown in the drawing), the tubers -/-/ of planting potatoes are periodically fed into the vertical funnel va of the telescopic seed tube 8 and through the bent inlet pipe 8b, the inclined outlet pipe 8c and its outlet end 8d fall in so z5 a furrow formed by a coulter-furrow 7. with

The discs and disc working bodies 9 located directly behind the furrow coulter 7 and at the required angle of attack roll up (bury) the potato tubers planted in the furrow and form ridges of loosened soil above them.

Due to the fact that the outlet pipe 8 of the seed duct 8 is inserted inside the opener-furrower 7 and is rigidly fixed in the latter (7), and the discs and disk working bodies 9 are located directly behind the sections) with the opener-furrower 7, their compactness is ensured layout in relation to the opener-furrow 7. . With such a layout, the distance between the outlet pipe 8b of the seed pipe 8 and the coulter-furrow 7, and y? Also, the distance between the seminal duct 8 and the disks of the disk working bodies 9 have a minimum value.

As a result, the horizontal distance between the steering wheel handles 5 and the disks of the disk working bodies 9 increases significantly, that is, the space for the operator's feet increases.

GI Due to this, the safety of the operator's work when driving the potato planting unit is significantly increased. co And the presence of a bevel 8g from the bottom of the outlet end 8d prevents clogging of the outlet pipe 8b of the seed conduit 8 - with soil.

The given information confirms the possibility of industrial implementation of the improved potato planting unit and indicates that the proposed technical solution meets the criterion of useful
