Description

The invention relates to agricultural machinery, in particular, can be used in the design of the shaft of new headers.

Known harvesters include a finger bar, a knife with a head, connected by means of a ball joint and a rocker arm with a mechanical LOW 10M drive, and a belt conveyor.

A disadvantage of the known headers is the need to lower the finger bar in the zone of connection of the knife head with the rocker. Usually this is achieved by installing (instead of standard) special fingers, which complicates the design of the header, reduces its strength, and increases the range of spare parts.

. The purpose of the invention is to provide the possibility of installing standard fingers on a palce bar in the zone of the connection of the knife head with the rocker.

This is achieved by the fact that, in the proposed header, the golfer is made in the form of an oil-cloth plate, while the ball spacing is placed between the upper and lower branches of the conveyor. In order to reduce

wear and heating of the knife gchelovka is equipped with a rod-shaped guide placed between the back of the knife and the ball joint.

FIG. 1 shows the proposed header, a general view; in fig. 2. - part of the cutting unit in the area of the head connection with the rocker; in fig. 3 is a section along A-A in FIG. 2; in fig. 4 is a section along BB in FIG. 2; in fig. 5 is a section along BB in FIG. 2; in fig. 6 shows a section along GG on FIG. 4. J

 consists of paid 1, reel 2, reel of the apparatus 3 and conveyor 4, the Cutting device includes a finger bar 5, on which bolts 6 behind-: fingers 7 are fixed and the knife is installed, consisting of the back of the knife 8 , segments 9; and head 1O knife. The head 1O of the knife has a ball joint 11 and the guide 12.. The knife head 10 is made in the form of a knee plate and is fastened with i 13 rivets with a front part to the back 8 of the knife c; 9.i segments

The guide 12 is made in the form of a rod and consists of two strips 14 and 15, the tail parts of which are fastened together by rivets 16 and fastened to the naked clothes 1O of the knife by welded seams 17 and rivets 18, the Guide 12 is installed in two guides 19. Each guide 19 comprises a lower plate 20, a side support 21 and an upper plate with a shoulder 22. Between the lateral support 21 and the upper plate with a shoulder 22, as well as under the bottom & The plate 2O accommodates adjustment pads 23. To simplify the installation of the adjusting pads 23 (without removing the bolts 24), they have open mortise holes - For structural considerations and because of their small size, the lateral supports 21 are also provided with mortise holes mi for rolts 24, installing the required number of adjustment plates 20 provides ;;: the required gap between the segments 9 and the cutting edge of the fingers 7, and installing the gaskets 23 provides a movable connection to the meiod of the guides 19 and the upper plate with the collar 22. Two bolts 24 are inserted from the top through the openings of the upper plate with the flange 22, the side support 21, as well as through the bottom plate 2O, the gaskets 23, the finger bar 5 and the fingers 7 are fastened with nuts 25. At the same time, the support 21 and the flange plate 22 must be pressed with its vertical planes against the guide 19, and the free movement of the guides 19 between the slider and the surfaces without jamming should be ensured. When installing the knife, the ball joint 11 times: -. 1e1tsatsya between the upper 26 and lower 2 7 branches. 1 “1 conveyor 4 header and connects the head 10 of the knife with the rocker 28) through the shackle 29, In p, 90yes work movement from the rocker arms 28 Cher§8 earring 29 and. the ball joint 11 is transferred to the head of the knife 10, and thus the back of the knife 8 rigidly connected with it and to the segments 9. Together with the head of the knife 10, the guide 12 moves. cop that acts 6 horizontal pdoskosti from behind the shoulder, to which the force of the yoke is applied. This shoulder is equal to the distance between the center of the ball joint 11 and the guide 12. The fingers 7 are standard in the joint area of the knife head 1O with the backrest 8 of the knife, and the fingerboard 5 across; the length is made of equal strength. Due to the approach of the guide 12 to the spherical joint 11, the forces pressing the guide 12 to the surface of the guides 19 are small, which reduces wear. and heating rubbing surfaces. The subject of the invention 1. A header containing a finger bar, a knife with a head connected by means of a ball joint and a rocker arm to a drive mechanism, and a belt conveyor characterized in that, in order to ensure that standard fingers can be installed on the finger bar a knife with a yoke, the knife head is made in the form of a cranked plate, while the joint joint is located between the upper and lower branches of the conveyor. 2.} (Atka pop, 1, characterized in that, in order to reduce wear and heat of the knife head, the latter is provided with a rod-shaped guide located between the back of the knife and the uia joint.
