Description

The utility model relates to agricultural engineering, mainly to harvesting equipment used in the harvesting of sunflower in breeding and seed production areas.

A known harvester for harvesting sunflower seeds containing stalk lifters with conveyors for collecting seeds, conveyors for advancing stems in the channels formed by stalk lifters, disk cutting machines installed at the outlet of the channels, a transverse screw conveyor with left and right coils for feeding the stems into an inclined chamber and drive (USSR AS No. 1667696).

Known reaper for harvesting sunflower, containing a frame mounted on it with stalk lifters, the casings of which form guide channels. Conveyors are placed along the guide channels to capture and advance the stems. At the output of each guide channel there are cutting devices. Between the guide channels are seed conveyors, made in the form of vibratory conveyors and mounted on a frame with an inclination towards the screw conveyor at an angle to the horizontal plane (RF Patent No. 2102856, A01D 45/00, 41/12, publ. 01.27.98).

The disadvantages of these harvesters for harvesting sunflower is the fact that they do not provide the ability to change the cutting height of the stems of sunflower, which leads to injury and loss of seeds, as well as their narrow scope.

Closest to the claimed technical solution is a header to a selection combine for harvesting sunflower, containing a frame for the header body, a frame for screws, stem dividers, screws, cutting pairs, a belt conveyor, hydraulic motors for driving screws, a drive shaft for seed sections (in breeding nurseries or hybridization sites) ), which is inherent in the prototype.

The problem solved by the claimed utility model is the expansion of the possibility of using a harvesting unit for harvesting sunflower by a selection combine.

The purpose of the utility model is to create a modular header design with the possibility of increasing the row width.

Utility Model Disclosure

The technical result is achieved by the fact that the known header to a selection combine for harvesting sunflower, containing a header frame suspended from the front of the combine, carrying frames of screws, screws, hydraulic motors for driving screws, stem dividers, belt conveyor, conveyor drive shaft, conveyor drive shaft, hydraulic cylinder for raising lowering the header body, a hydraulic cylinder for raising and lowering the screw frame, according to a utility model, further comprises a conveyor belt, a central stalk divider with two screws on a separate frame, w pivotally fixed with its lower part on the header frame, a transverse auger with left and right coils mounted on the header body, a mechanism for adjusting the angle of inclination of the screws to the field plane, including an axis pivotally mounted using brackets on the header frame parallel to the transverse screw, three leashes and three rods, each of which is fixedly connected at one end to one of the hydraulic cylinders for raising and lowering the screw frame and to one of the leads, which is pivotally connected at the other end to one of the screw frames, belt conveyors Credited with both sides of the central divider stems.

Brief Description of the Drawings

The figure 1 schematically shows a reaper for a selection seed harvester for harvesting sunflower (top view); in FIG. 2 - the same (side view).

The inventive header includes a header frame 1, auger frames 2, augers 3, cutting pairs 4, hydraulic motors 5 for driving augers, dividers 6 stems, belt conveyors 7, a drive shaft 8 conveyors, a hydraulic cylinder 9 for raising and lowering the header frame, hydraulic cylinders 10 for raising and lowering screw frames, central divider 11 stems, transverse screw 12, axis 13, hinges 14, brackets 15, rods 16, leashes 17.

The technical result of the claimed utility model consists in expanding the possibility of using a harvesting unit for harvesting sunflower by a selector due to the possibility of increasing the width of the rows. This is explained by the following.

A selection harvester with a well-known reaper (according to the prototype) can harvest only two rows of sunflower in one run. This happens as follows: during the movement of the combine with the reaper, the plants fall into the channel, are captured by screws and transported to the cutting pair. The conveyor belt feeds the cut baskets to the threshing device of the combine. And with the inventive reaper, the selection combine can clean four rows in one run due to the distinctive features of the inventive reaper: a central stem divider (DDS) with two additional screws, a transverse auger with left and right coils mounted on the header body, and a mechanism for adjusting the angle of inclination of the augers to the plane fields, including an axis, three rods and three leashes, an additional conveyor belt. Moreover, the inventive header design is modular, i.e. provides the possibility of building up its elements to increase the width of the reaper header of a larger number of rows without drastic changes in its design.
