Description

f

The invention relates to the field of agricultural machine building. NIN, namely to roller headers with waste window for laying cut plants in the roll.

By bus. St. W 268778 is a well-known roll header with outflow window, containing a transverse conveyor and a working member mounted above the ejection window of the rotation, which is made in the form of a slatted reel to prevent congestion and blockage.

Most roller headers operate on the principle of laying rolls in the middle. The quality of the roll positioning is determined, besides the average throughput height, which can be quite large, first of all by the width and height of the passage between the transporting bodies. For most designs they are limited to the main machine. Therefore, in a well-known machine, good laying quality is achieved only when the bread-bearing stems are up to 1.3 m long. With longer stalks, especially when the direction of transportation changes from transverse to transfer in the longitudinal direction, congestion occurs. The long stems supplied to both sides move against each other, which leads to poor-quality and uneven planting in the roll. This poor-quality roll-up can also not be changed due to the slatted reel installed above the exhaust window. For the subsequent selection of rolls by a combine harvester, a well-laid swath is the main condition for harvesting with the least losses.

The purpose of the invention is to create a working organ for guiding the harvesting weight in the roll headers for harvesting grain crops, which cleanly rolls into the rolls also the long-stretch crop and provides for harvesting with the least losses.

The invention is based on the task of creating a working body that will align the laying of BL5 from both transporters of cut plants to the middle of the outflow window, ensure the creation of a uniform inlet and reduce its height.

S in accordance with the invention, on a crossbeam located in the upper zone of the frame of the log header, brackets are mounted to which support plates are detachably attached so that they are symmetrical to the cross conveyor and are above it. On the base plates movably to the point of rotation

 brackets mounted between which the shaft is mounted. The shaft mounted in front of the rear frame is provided with disks fixed to it and spaced along its entire length and installed above the outflow window between the two conveyors. The shaft is driven by a longitudinal shaft mounted on a crossbeam and connected to a reversible chain.

20 transfer. Curved fingers made of varying height from the middle of the shaft to its periphery are fixed to the disks. Shaft with brackets moving upward rests on points

25 rotation of base plates. Due to the movable stops installed in the lower part of the base plates, adjacent to the lower edges of the brackets, the movement of the latter downwards is limited. Iodine

30, a shaft is installed between the individual discs and a cleaning disk sheet that is removably attached to the roll header frame.

The proposed tool is designed for roller headers when harvesting long-length or bulky crops, such as rapeseed, etc., and allows stacking into rolls in the form of a fan or in the form of a roofing tile between the wheels of the main machine. When laying short-stem wolves: 1and middle-grade crops, the working body is easily removed from the -v brackets of the crossbeam by eroding bolted joints.

. When harvesting lengthy and bulky crops, the working body is mounted on the base plates on

 crossbeam brackets. The stops mounted on the support plates are adjusted so that the shaft

, occupy a certain height in accordance with the state of the stem mass. A cleaning 55 sheet mounted under the discs is attached to the header frame so that, with its upturned end, it is just below the disc flange plates.

The proposed roll header 1 through a lifting device 2 is detachable and movably connected to the base machine 3. The header 1 consists of frame 4, reel 5, cutting unit 6 Yu and two transverse conveyors 7 located between the outer sides and the middle of the machine. The cutting unit 6 is driven right through the input shaft 8, while t5 drives the reel 5 and transverse conveyors 7 through the longitudinal shaft 10 driven by the input shaft 8 through a chain transmission 9. The longitudinal shaft 10 is mounted on the crossbeam 11 of the frame 4 and is located across the entire width of the header 1. On the crossbeam 11, symmetrically to the internal turning points of both cross conveyors 7, the brackets 12 are installed for mounting the folding brackets 13. The brackets 13 have a shaft 15 that overlaps The outflow port 14 is formed between the transverse conveyors 7. The shaft 15 is provided with disks 16 spaced across its length, at intervals, with curvilinear spring fingers 17 that decrease in height from the middle of the shaft 35 15 to its periphery. The shaft 15 is driven by a longitudinal shaft 10. To this end, support plates 18 are attached to the brackets 12, which are located 40

Inclined upwards and on which the brackets 13 are installed and a reversible chain drive mounted, driven by the drive shaft 10. At the turning point 20 of the bracket 13, an asterisk 21 is installed, providing the drive shaft 15 by means of a chain transfer 22. Under the shaft 15, a curved upward cleaning is installed the sheet 23, which is detachably attached to the frame 4. The brackets 13 at the pivot points 20 can be rotated upwards, while their angle of rotation is limited by the stops 24 mounted on the plates 18.

We offer -katka works as follows.

The stem mass cut by the cutting apparatus 6 is placed on transverse conveyors 7 on both sides and then in an intermediate drop zone, with the stem mass laid on the conveyors 7 being brought to the middle on both sides of the stem mass already there. In this case, the disks 16 fixed with them rotating on the shaft 15 rotating in the direction of laying, with spring fingers 17 fixed on them, direct this stem mass to the outflow port 14 for laying on a roll. The rotating discs 16 align the height of the roll so that when driving through the base machine there would be no damage to the laid roll. Such ordered stacking allows the combines to pick up the crop with the least losses.
