Abstract

FIELD: agricultural engineering. SUBSTANCE: header has platform 1, feeding device and stalk lifters with plant passage guides. Feeding device has central shaft with transporting members, with number of transporting members corresponding to number of plant passage guides. Each transporting member is formed as circular member 9 with curved gripping parts 10 which are kinematically connected with race of immovable feeler 13. Feeler race is positioned concentrically with respect to drive shaft. Each stalk lifter 6 is made in the form of trough with arrow-shaped netted walls 7 positioned on front part of trough. EFFECT: increased efficiency and simplified construction. 2 dwg

Description

 The invention relates to the field of agricultural engineering, in particular combine harvesting, and is aimed at improving the header for harvesting sunflower.

 Known universal eccentric reel containing rake, articulated in wooden beams. Cranks are welded to the ends of the rake, on the fingers of which the rays of the eccentric mechanism are worn / 1 /.

 A disadvantage of the well-known reel is that when it is used to harvest sunflower, the reel planks strike a direct and severe blow to the baskets, as a result of which a significant part of the crop is lost by freely ground seeds.

 It is also known reel to the header of the combine harvester, consisting of a central shaft and three or four planks standing at an equal distance from it, and the space between adjacent planks is covered with a wire mesh with cells of smaller sizes of harvested sunflower baskets / 2 /.

 The design of such a reel along with a decrease in the degree of injury to the seeds does not exclude their significant losses.

 Known reaper for harvesting sunflower containing stalk lifters with a chain circuit for gripping and promoting stems located under the chain circuit with a cutting apparatus for cutting baskets and a device for transferring baskets to the working bodies transporting the mass to the thresher / 3 /.

 When using the well-known reaper, the loss of sunflower seeds is significantly reduced. However, due to the complexity of its design, this reaper does not ensure reliable performance of the technological process and allows for the loss of seeds.

 The aim of the proposed technical solution is to simplify the design along with reducing the loss of seeds of the harvested crop.

 This goal is achieved by the fact that in the header for harvesting sunflower containing a platform, a feeding device and stalk lifters with channels for plant passage, according to the invention, the feeding device is made in the form of a central shaft with transporting bodies in an amount equal to the number of channels for plant passage, each the transporting body is made in the form of a circle with curved gripping elements that are kinematically connected with the running track concentrically located relative to the drive shaft Coy fixed cam furthermore has a shape steblepodemnik each trough at the bow of which are set streloobraznye reticulated wall.

 The invention is illustrated by drawings, where in FIG. 1 shows a general view of a header for harvesting sunflower; in FIG. 2 is a plan view.

 The header consists of a platform 1, on which there is a screw 2, an inclined conveyor 3, a cutting apparatus 4, dividers 5, window lifters 6, which have the shape of a trough, which minimizes the loss of sunflower seeds. On the bow of each stalk lifter 6 mounted arrow-shaped mesh walls 7, which contribute to the lifting and supply of sunflower stems in the beds of the harvester header.

 The feeding device is made in the form of a central shaft 8 with transporting bodies in an amount equal to the number of channels for the passage of plants.

 Moreover, each transporting body is made in the form of a circle 9 with curved gripping elements 10, which are kinematically connected via a crank with a roller 11 to a treadmill 12 of a stationary copier 13 concentrically located relative to the drive shaft.

 The reaper works as follows. As the combine is moving along the field, the window lifters 6 together with the arrow-shaped mesh walls 7 of the header send sunflower plants to the working channels and into the zone of action of the picking elements 10 of the transporting body, which in turn tilts the sunflower stems onto the header platform 1 at the time of cutting with the cutting device 4 .

 After cutting the plants and feeding them to the header platform, the activity of the exciting elements 10 of the transporting organ is reduced to a minimum, and they themselves rotate around their own axes, flush with the circle 9.

 The curved shape of the gripping elements 10 ensures their smooth entry into the area of the working channels, by tilting and feeding the plants cut by the cutting apparatus to the header platform 1.

 The capture of the next batch of sunflower plants by the subsequent capturing element 10 of the conveying organ is carried out similarly.

 The proposed header design provides without loss and injury to the seeds, the slope, cut and supply of sunflower baskets to the combine thresher due to the lateral impact of passive and active feeding devices.
