Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The invention allows to increase the reliability of the process of unloading grain from the bunker. The shafts of horizontal 2 and inclined 3 screws are connected to each other with the aid of universal joint 4. Two half-rolls 7 of a separate two-way spiral are mounted on the input section of the shaft of the inclined screw 3, between which are mounted blades 8 mounted on the shaft of screw 2, This mutual arrangement of half-turns 7 and the blades 8 provides for the formation of a dead zone in the transition pipe 6 by a winding screw auger screw 2 and the hinge 4. 1 Il.

Description

The invention relates to agricultural machinery and can be used in the construction of combine harvesters.

The purpose of the invention is to increase the reliability of the process of unloading grain from the bunker,

The drawing shows a diagram of the unloading device of the bunker.

The unloading device comprises a horizontal screw 2 installed in the hopper 1 and an inclined lug 3, the shafts of which are connected to each other by means of a universal joint 4. The screw 3 is mounted in the casing 5 movably connected to the hopper by means of an adapter 6, on the output shaft of the inclined auger 3, a separate screw was installed, made of two half-turns 7 with the formation of a two-way spiral. On the shaft of the horizontal screw 2 mounted blades 8, placed between the semi-turns 7,

The device works as follows.

When the device is turned on, the rotation from the horizontal auger 2 to the inclined auger 3 is transmitted through the universal joint 4. In this case the semi-turn 7 and the blades 8 also rotate.

The position of the latter with an angular displacement relative to the half-turns 7 creates an overlap of the zones of action of the blades and half-turns, which allows eliminating the dead zone between the hinge 4 and the auger screw of the screw 2, prevent clogging of the nozzle 6 with grain, and thereby increase the reliability of the device.

Formula of invention

A hopper unloading device for a combine harvester that contains a horizontal auger mounted in the hopper, an inclined auger mounted in the housing, movably connected to the hopper by means of an adapter, a universal joint connecting the augers shafts to each other, and mounted on the inclined auger input shaft of an inclined auger a separate auger auger shunt auger with an individual auger , in view of the fact that, in order to increase the reliability of the process of unloading grain from the bunker, a separate wound screw was made of at least two half-turns with two-way helix, and the shaft of the horizontal auger is equipped with blades located between the semispieces.
