Description

(54) HEADER AUGER CONVEYOR

one

FIELD OF THE INVENTION The invention relates to agricultural machinery and can be used in the harvesters of a combine harvester.

The header screw conveyor is well-known; it contains a spiral hollow shaft mounted on the header side walls by means of supports and a chute located under the hollow shaft, with grooves in the hollow shaft in which fingers 1 are mounted on the crankshaft.

A disadvantage of the known device is that it does not exclude the winding of the stem mass on the tubular screw shaft in the area of the supports.

The purpose of the invention is to reduce the possibility of coiling the stem mass in the area of supports.

This goal is achieved by the fact that at least one of the sidewalls has a recess in which the end of the hollow shaft is located, having additional grooves, the conveyor being provided with additional fingers which are mounted on the crankshaft and are located in the additional grooves.

FIG. 1 shows a screw conveyor with a support, top view; in fig. 2 - support tubular shaft; in fig. 3 shows section A-A in FIG. one.

The screw conveyor contains a transport chute 1 with sidewalls 2 and 3, on which the hollow shaft 4 is supported. On the hollow shaft 4 there are two spirals 5 and 6. There are a recess 7 in the sidewall 2 of the transport chute 1, in which the end Q of the hollow shaft 4 On the outer side of the sidewall 2 there is a support 8 of the hollow shaft 4, in the middle part of which the fingers 9 are mounted, placed in 4 slots made in the hollow shaft.

In the cavity of the hollow shaft 4 on the shaft 10,

15 which is located eccentrically to the tubular axis 11, the shaft, rotatably and radially this axis, an additional pin 11 is installed with the possibility of periodic reciprocating relative to the additional groove 12.

The parameters of the eccentricity of the shaft 10 installation relative to the axis 11 of the hollow shaft 4, as well as the additional finger 11 are selected from the condition of the location of the end 13 of this finger at the level of the additional groove i2, when the finger is in its extreme position and extending beyond the helix 5 in position The work of the header sidewall 2 is located st) side unbread bread. When the rotating hollow shaft 4, by means of the coils 5 and 6, moves the weight of the stem fed into the transporting groove towards the center of the header, the eccentrically located additional finger 11 rejects the stem mass from the support zone 2 together with the hollow shaft 4 and thereby reduces the possibility of winding it on the hollow shaft 4 in this zone. Moving reciprocating axially, the additional finger 11 is self-cleaning and eliminates the possibility of mass accumulation on the finger itself. The invention is not limited only to the described embodiment. It is also possible to perform a screw conveyor with one spiral tape located on the tubular shaft, as well as the installation of radial fingers on both sides of the header. V v vlllllll
