Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to conveyor pick-ups of rolls of skewed grain mass. The aim of the invention is to reduce grain losses by cleaning the pick-up fingers from the stems. The pick-up consists of a conveyor 1 mounted on shafts 2 and 3 with fingers fixed thereto 4. Along the upper shaft 2, a stalk collector 5 is installed, from which the stalks enter the pitched board 6. When the pick-up is in operation, the fingers 4 pass between the turns or zigzag projections of the stitcher, who under the blows of his fingers makes vibrations. 2 hp f-ly, 5 ill.

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to conveyor pick-ups of rolls of skewed grain mass, which are used for separate harvesting of grain crops.

The purpose of the invention is to reduce the loss of grain by cleaning the pick-up fingers from the stems.

FIG. 1 shows a pick-up, side view; in fig. 2 - the same, top view; Fig 3-5 shows respectively a frontal view from above and a side view of a stem remover made in the form of a zigzag elastic element.

The pick-up consists of conveyor 1, mounted on the top 2 and bottom 3 shafts. Pick-up fingers 4 are located on the conveyor. The stalkbinder 5 is mounted above the pitched board 6 along the upper shaft 2.

Picker works as follows.

When the conveyor 1 moves on the rotating shafts 2 and 3, its pick-up fingers 4 pass between the turns or zigzag projections of the spring strap-up puller 5. As a result, the stem remover 5 scoops the remaining stalks from the pick-up fingers 4 and prevents their loss. At the same time, the pick-up fingers 4 strike the spring stalk collector 5. As a result of the blows, transverse, longitudinal and twisting oscillations of the stalk remover 5 occur.

The versatile vibrations of the steamer 5 improve the cleaning of the fingers 4 and the remnants of the stems from it. The stems removed by the steamer 5 fall onto a sloping board 6 or other transporting organs. Thus, there is a decrease in grain losses due to the fact that the stalk puller 5 cleans the 4 stalks remaining on the fingers and prevents them from falling to the ground.

The steamer 5 can be made, for example, of steel elastic wire in the form of a twisted spring (Fig. 1, 2, item 5) or in the form of a zigzag spring (Fig. 3-5). The distance between the turns or zigzag protrusions of the stalk collector 5 should be commensurate with the distance between the pick fingers 4.

Claims (3)

1. The picker, which includes a conveyor 0 with pick-up fingers and a stalk picker located along the upper conveyor shaft at a distance shorter than the length of the fingers of the conveyor, characterized in that, in order to reduce grain losses due to cleaning the fingers from the stalks, the stalk puller is designed as elastic element with protrusions placed in between the fingers of the conveyor. 2. A selector according to claim 1, characterized in that the resilient element is designed as 0 zigzag bar in two planes. 3. Pick-up according to claim 1, characterized in that the resilient element is designed as a spring. five s Schig.2 r Phi.E FIG. H FIG. five
