Description

(54) HEADER

one

The invention relates to agricultural machinery and can be used primarily for harvesting crops with curled and laid stem mass (peas, vetch, etc.) harvested both at the stage of full ripeness for grain and in the premature state for silage or green fodder.

The header is known, containing a cutting apparatus attached to the frame, bar stem lifters and field dividers, each stem lifter and divider having a support heel and fixed on the frame 1.

A disadvantage of the known harvester is the significant loss of the mowed weight, especially when harvesting crops with a laid stem mass, as a result of the possible omission of stem lifters and dividers spreading along the ground stalks.

The purpose of the invention is to reduce the loss of mowed mass.

This goal is achieved by the fact that the ends of stem lifters and field dividers are bent down.

FIG. 1 shows a schematic invention of the header, side view; in fig. 2 - the same, top view.

The harvester contains frame 1, on which field dividers 2 are installed, stem lifters 3, eccentric reel 4, cutting unit 5 and longitudinal conveyor 6. Frame 1 has support wheels 7. Steamer lifters 3 are tubular rods, one ends of which are hinged

10 are fixed on the transverse beam of the frame 1, and the others have a supporting heel with the end bent down. The cutting unit 5 is made with shortened contradictory fingers that have interchangeable shearing plates.

Field dividers 2 are hinged on frame 1 and are rods with tips having the form similar to those of stem lifters 3. Rods carry steel rods on themselves,

20 forming a tapered frame. At the large base of the frame, swinging active knives 8 are installed to cut the stems of the dividers not divided by the rods 2. The longitudinal conveyor 6 contains a canvas belt with transverse strips stretched over two rollers. The downstream back roller is leading. The rear end of the frame 1 is pivotally attached to the vehicle 9. The drive elements of the header contains a power take-off shaft 10, a chain 11, a counter-drive shaft 12, a propeller shaft 13, tapered gears 14 and 15, a drive shaft 16, a chain 17, a drive shaft 18, a mechanism 19 drive cutting device 5, made on the principle of swinging washers, drive sprocket 20, chain 21, shaft 22 reel 4 and cranks 23 of the drive shaft 16. The active knives 8 of the dividers 2 are telescopic rods, on the guide rods x-backs of which are fixed segments. Anti-backing with segments fixed pivotally on the uprights of the frame 1. The heads of the knife segments are connected to the fingers of the cranks 23 of the drive shaft 16. In the process, the header steamer 3, the slips with their tips on the surface of the soil, lift the stalks of good weight. The reel pins 4 capture the raised mass layer and drag it along the stem lifter 3 rods to the longitudinal conveyor 6, together with which they create tension on the stems. At this moment, the mass is separated from the root system by the cutting apparatus 5, and from the field part - 8 field dividers with rods and active knives 2. The cut-off mass passes through the conveyor 6 and is placed on a roll on the ground between the wheels of the vehicle 9. The longitudinal conveyor 6 with its reverse branch cleans the stem lifter 3 rods from the stalks at their hinge to the frame 1. The ends of field dividers 2 and stem lifters 3 are bent down and the presence of the reference flux ensures that they reach the surface of the soil at possible bogs. The proposed design reduces the loss of mowed weight. Claims of the invention: A harvester comprising a cutting apparatus mounted on the frame, bar stem lifters and field dividers, each stem lifter and divider having a support heel and fixed on the frame, which is designed to reduce the loss of mowed weight, the ends of the stem lifters and field dividers are bent down.
