Abstract

Usage: the invention relates to agricultural machinery. SUMMARY OF THE INVENTION: a drum pick-up comprises a drum with picking fingers and 4 frames mounted on the cross member located between the fingers and covering the ramps 6. The sides 3 of the drum frames in the longitudinal direction are rigidly fixed to the sides 8 of the conveyor belt mounted behind the drum, in the transverse direction of the side walls 3 interconnected by means of the shafts of the conveyor and the drum and the cross member 4 with the possibility of rotation relative to the longitudinal axes of the shaft of the conveyor and the drum. The proposed connection of the working bodies provides a reduction in yield losses due to the achievement of a constant in the direction of supply of the selected stems on the header platform. 3 silt

Description

f # g1

The invention relates to the field of agricultural engineering, in particular to machines for selecting rolls of grain crops in a two-phase harvesting method. It can be used for the selection of straw, hay, haylage, other feed, as well as flax, hemp and other long-growing industrial crops.

The aim of the invention is to reduce losses by providing a constant direction in the direction of supply of the selected stems to the header platform.

In FIG. 1 shows a general view of the proposed pick-up; Fig. 2 shows the possible positions of the pick-up in the process of copying floor irregularities; in Fig.3 is a diagram of the rotation of the shafts and sidewalls when copying.

The drive shaft 1 of the pick-up is installed in the bearings 2 of the sidewalls 3 of the pick-up frame. The sides 3 are connected by a cross member 4, to which slopes 6 are fastened with brackets 5, covering the pick-up drum in the spaces between the fingers 7. The sides 3 of the pick-up frame are fixed to the sides 8 of the conveyor belt. The belt conveyor is formed by the leading 9 and the driven 17 shafts and the web 10 covering these shafts. The drive shaft 9 is mounted in bearings, the housings of which are mounted on the header 11 of the combine. The housing 12 of the bearings of the sidewalls 8 are mounted rotatably relative to the inner cages fixed rigidly on the shafts 9 and 17. The support wheels 13 are mounted in the vane forks 14, the brackets 15 of which are fixed on the sidewalls 3 of the pick-up frame and 8 of the conveyor belt. The springs 16 of the unloading device are fixed at one end on the axes of the vane forks 14 and the other in brackets on the combine header (not shown).

The picker works as follows. When the harvester moves along the roll, fingers 7, rotating towards the harvester in the upper position, rake the stems to the total mass of the roll, then lift the roll, tear it away from the stubble and transport it along slopes 6. The selected roll moves under the action of finger 7 and its own elasticity along the fixed slopes 6. and unloaded onto the conveyor belt. Due to the elasticity of the roll and friction forces arising between

conveyor belt 10 and stems, the roller is transported by tape and fed into the gap between the screw and the bottom of the header, due to the constant position of the upper

conveyor shaft relative to the screw and bottom. The support wheels 13 are mounted so that the fingers 7 of the pick-up completely comb the stubble all the way to the soil, selecting all the stems from the surface

gender When the wheel 13 copies irregularities in the floor, the pick-up is rotated relative to the upper conveyor shaft 9 in the sidewall bearings. At the same time, the pick-up, the conveyor sides 8, the lower driven conveyor shaft 17 and the forks with support wheels are rotated in the transverse direction (see Figs. 2 and 3). The sides of the conveyor are displaced one relative to the other, remaining parallel

due to the connection with the cross member of the frame.

The components of the cross member rotate one relatively arc around the longitudinal axis of the cross member. In this case, the picking drum remains parallel to the surface of the floor, and the position of the upper shaft relative to the screw and bottom remains unchanged. Thus, when transversely copying the relief of the floor, the direction of supply of the stems into the gap between

the screw and bottom remain constant. The speed of movement of the conveyor belt is selected from the condition of timely removal of the stems from the picker, and the speed of the picking fingers from the condition of the continuity of the flow of picked stems. . The claims A drum pick-up comprising a drum with pick-up fingers installed in the bearings of the sidewalls of the frame and fixed on the cross member of the frame, located between the fingers and covering the drum slopes, characterized in that, in order to reduce crop losses, the pick-up is equipped with a conveyor belt mounted behind the drum on an additional frame, the sides of which are rigidly connected in the longitudinal direction to the sides of the drum frame, and in the transverse direction, these sidewalls interconnected by means of the conveyor and drum shafts and the cross-members of the drum frame with the possibility of rotation relative to the longitudinal axes of the conveyor shaft and the drum. t
