Description

The utility model relates to sowing machines, is an integral part of their design and is designed to provide optimal operating conditions for seeders in an aggregate of three or more seeders.

Two options are known for connecting seeders-cultivators into an aggregate: a connecting link (option 1) and a connecting device (option 2), which are used in aggregates of seeders-cultivators SZS-b, SZS-12. See Seeders-cultivators SZS-6, SZS-12 grain wide-reach stubble non-chain, M., 1990, ed. Information Technical Committee of the State Commission of the Council of Ministers of the USSR for Food and Procurement, SZ, Fig. 1, c (1).

In these units, the connecting link (option) pivotally connects the seeder-cultivators, namely: the bracket mounted on the frame of the left seeder and the spherical hinge mounted on the frame of the right (adjacent) seeder are connected by a vertically located axis. The connecting link provides the possibility of vertical movements of two adjacent seeders, as well as their rotation relative to each other on a spherical hinge.

To limit the vertical movements of the extreme seeders in the working position, a connecting device is provided (option 2), which has one degree of freedom less than the connecting link. Here, a spherical hinge mounted on one seeder is connected to another bracket with a horizontal axis, and the staples are fixed respectively on the left and adjacent right seeders, which

have three degrees of freedom and can rotate relative to each other on a spherical hinge.

The drawback of the data of the connecting link (option 1) and the connecting device (option 2) is that when setting up and preparing the wide-grip multi-seeder unit for operation, it is practically impossible to compose the seeder unit so that during operation the traction resistance of each seeder is transmitted to the tractor through the seeder hitch ( and that the seeders move parallel to each other), and not through an adjacent seeder, that is, through a connecting link or connecting device,

In this case, the seeders in the unit come with some bias in the direction of travel. This negative phenomenon is especially observed during the operation of the unit on curved rutting and cornering. This leads to deformations and breakdowns of the connecting links and connecting devices, which leads to significant downtime to resolve these problems. In addition, the quality of the seeders is deteriorating, its traction resistance is increasing, which ultimately leads to a decrease in the performance of the seeder unit.

The purpose of the proposed utility model is to create a more advanced design of the connecting device in two versions, operating in the same unit, giving the seeders an additional one degree of freedom, which would make it possible to move adjacent seeders in the unit relative to each other by a certain amount in the horizontal plane in the direction of travel seeder unit.

This goal is achieved by the fact that the designs of the connecting device according to the first and second options, in comparison with existing analogues, provide an additional one degree of freedom and allow two adjacent seeders in the unit to move

- 2 relative to each other by a certain amount in the horizontal plane in the direction of movement of the unit.

And this allows you to compensate for various errors in seeder trailers and implement couplers along their length along the movement of the unit, that is, errors in dimensional chains, and ultimately make up a workable and reliable seeder unit, while the traction resistance of each seeder will be transmitted to the tractor through seeder hitch and at the same time connecting devices of seeders will work without deformation and breakage.

The closest analogue of the proposed utility model can take the connecting link (option 1) and the connecting device (option 2) used in the wide-angle multi-seeder units SZS-6 and SZS-12 (1).

The list of figures in the drawings.

Figure 1 shows the connecting device option 1, a rear view in the direction of movement of the unit. In Fig. E shows a view aa of Fig. 1.

Fig. 3 shows a partial section B-B of Fig. 2 with a roller sleeve. Figure 4 shows a partial section BB of Figure B with a rectangular slider in cross section.

Figure 5 shows the connecting device option 2, a rear view in the direction of movement of the unit. In Fig.6 shows a view of G of Fig.5.

The proposed utility model. The connecting device of a wide-seeding multi-seeder unit (2 options) consists of the following units and parts.

In Fig.1,2,3,4 depicted option.

- 3 bracket 4 with a vertically arranged through groove.

In two holes in the eyes of the bracket bracket 2, the axis 5 is fixedly mounted on which the sleeve-roller 6 is mounted with free rotation. Instead of the sleeve-roller 6, a slider 7 (Figs. 1, 3 and 4) can be used, which has a rectangular shape in section.

1, 2, 3, 4, 4 shows a connecting link device providing five degrees of freedom of movement of the seeders 1 and 3 relative to each other: along the y axis by an amount along the axis around the x, y, axes.

Figure 5, b shows the connecting device option 2, which consists of a bracket 8 with a spherical hinge 10, mounted on the frame of the left seeder 1 and bracket-brackets 9, mounted on the frame of the right (adjacent) seeder 3, and interconnected by an axis 11 .

The connecting device in option 2 provides four degrees of freedom, one less than in option 1 of the movement of adjacent seeders relative to each other: along the y axis in the horizontal plane by -; around the x, y, 2 axes on a spherical joint.

the use of the proposed design of the connecting device of the wide-seeding multi-seeder unit in two versions allows the traction resistance of each seeder to be coupled to the coupler due to the fact that each seeder is able to move a certain amount relative to the adjacent seeder in the horizontal plane in the direction of the unit, and this significantly reduces the value longitudinal load on the connecting device, which eliminates their deformation and breakage.

- 4 connecting devices, and ultimately increases the performance of the seeder unit.
