Description

Tractor adapter for roller header.

The proposed utility model relates to agricultural production, namely to harvesting grain crops.

It is known to combine a tractor with a specialized header designed to work with a tractor (guidelines “Mounted header ЖН-4.0 device, assembly, use, care, 1958, s, 1-20).

However, specialized reapers are rarely used because of their high cost and complexity of operation.

Closest to the proposed utility model (prototype) is an adapter for aggregating the header with a tractor (g. Tractors and agricultural mapping machines, 1997, N4, p. 12-13), which is a frame structure of square or round pipes welded together and reinforced plates and kerchiefs made of sheet iron. To install the adapter, a U-shaped tubular section frame is cut from the header. Attachments under the hinges of the adapter frame are welded to the remaining main tube of the header frame, allowing you to copy the soil relief, and a platform for installing the gearbox.

Hinge mounts are made of sheet steel. The platform for the gearbox is a welded construction made of sheet steel with a thickness of 68 mm. The adapter frame and header are connected to each other by springs, which provide header vibrations and copy soil relief. The springs borrowed from the inclined chamber of the SK-5M Beer combine are installed parallel to the header header. They are fixed on specially machined axes welded to the upper beam of the header, and connect the adapter to the header through a system of levers and adjusting rods. To drive the working bodies of the header, the driveshaft from the gearbox is extended and the corresponding kgfdana from the tractor PTO to the gearbox is selected. In this case, the gearbox platform is set so that the angle of inclination of the driveshaft from the tractor PTO to the gearbox in the raised position of the header is at least 15 °.

However, this device is very metal-intensive, does not allow the header to completely copy the soil profile, and, most importantly, the use of this device is impossible without changing the design of the header.

The technical task of the utility model is to provide such a connection between the tractor and the roller header, which will allow it to ensure the operability of the header without changing its design, that is, the header can be used both with the tractor and with the combine, will allow the header to more smoothly copy the relief of the field surface, as well as will reduce the metal consumption of the structure.

The problem is achieved in that in the adapter for the tractor for the roll header, containing a welded beam with brackets for mounting the adapter to the header frame, brackets for attaching the horizontal links of the tractor rear linkage, a platform for the gearbox, according to the invention, the brackets for attaching the adapter to the header frame are rigidly fixed to welded adapter beam and have holes for the fingers, with the help of which the adapter is mounted on the header frame, the platform for the gearbox is made integral, consisting of two channels, in which There are holes for contour bolts that secure the platform to the header frame, as well as holes for attaching the gearbox.

Unlike the prototype, thanks to the proposed design of the mounting brackets of the adapter to the header frame, the platform for the gearbox, it became possible to separate the springs and adjusting rods from the adapter, which allowed to obtain better copying of the field surface.

The originality of the proposed technical solution lies in the fact that due to such an arrangement of the mounting brackets of the adapter to the header frame, and such a design of the platform under the gearbox, there is no need to change the header design (since the adapter is removable there is no need to cut the lower header beam), which allows using the header as with a combine harvester and with a tractor; due to the separation of the adjusting rods and springs from the adapter, the metal consumption of the adapter is significantly reduced and better copying of the field surface is achieved.

In FIG. An adapter is shown for connecting a tractor to a roller header; figure 2. - horizontal projection of the unit; on fig.Z. - frontal view of the harvesting unit.

The proposed device consists of a welded beam 1 (figL), which is a square or round pipe, at the ends of which, by welding, the crownpieces 2 of the adapter 3 (figure 2) are fixed to the frame 4 of the header 5, with holes for the fingers 6, On the side of the pork beam, perpendicular to it, by means of welding, the crown crowns 7 (FIGL) of the horizontal linkage 8 (FIG. 2) of the rear linkage of the tractor 9 are attached, the crushegains are made of sheet steel six to eight mm thick, the platform for the gearbox 10, consisting of two Pseller 11 (FIG), which is rigidly to repeats on top of the beam, holes are made in the channels for mounting the gear 12 (Fig. 2), which provides torque transmission from the power take-off shaft 13 ipaKTqja, through the driveshaft 14 (Fig. 3), to the gearbox 15, header drive mechanisms; as well as holes for the contour bolts 16, securing the platform under the gearbox to the header frame.

Copying the topography of the soil is achieved: in the horizontal plane due to two spring blocks 17 and adjusting rods 18, and in the vertical - due to the hinged floor of the tractor frame. The springs at one end are attached to the rear linkage of the tractor, and at the other to the brackets 19 (Fig. 2) on the vertical stand 20 of the header, with the help of fingers 21. Regulating wheels are fixed to the central link 22 of the tractor link, and to the brackets 23 welded to vertical stand header.

This design adapter) has a significantly lower metal consumption compared to the prototype, ensures the performance of the header without changing its design, and gives the best mowing of the field surface.

The proposed adapter) works as follows. The adapter 3 (Fig. 2) is mounted on the lower beam of the header 4 with the help of the brackets 2 for attaching the adapter to the frame of the header, which are mounted on it and fixed with four fingers 6, to the crown arms 7 (Fig. 1) of fastening the horizontal links of the tractor rear linkage with the help of fingers horizontal rods 8 (Fig. 2) of the tractor hinge are connected 9. The free end of the platform for the gearbox 10, using contour bolts 16, is connected to the header frame 5, a gearbox 12 is mounted on it, with which the tractor power take-off shaft 13 is connected, and the cardan shaft 14 from redu Ktora 15 (Fig.Z) drive header mechanisms.

The springs 17 are fastened with one wheel to the rear linkage of the tractor, and with the other to the brackets 19 (Fig. 2) on the vertical stand 20 of the header using the fingers 21. Adjusting rods are attached to the central link 22 of the tractor link, and to the crown gears 23 on the vertical stand of the header .

Thus, the use of the proposed device will achieve the following skinny results:

1. The design of the adapter allows you to ensure the health of the header without changing its design.

2. The independent arrangement of springs and adjusting drafts allows to more smoothly copy a relief of a field surface.

3. Due to the separation of springs and adjusting rods from the adapter, the metal consumption of the constructions is significantly reduced.

The implementation of the potentials of the proposed technical solution does not require large material and energy costs, and is distinguished by the availability of the adapter device.
