Abstract

The invention relates to agricultural machinery, in particular to combine harvesters. The goal is to reduce the dimensions of the combine. The frame comprises front and rear parts consisting of upper and lower owls. The lower rails are formed from longitudinal beams with cross members, the upper one from the front part is formed by longitudinal rails installed at an angle to the lower ravine beams and to each other. The lower front beams are installed at a distance shorter than the rear frame beams, 4 il.

WITH

FIELD OF THE INVENTION This invention relates to a support frame for a combine harvester comprising a longitudinally thresher threshing apparatus for axial flow and a vibratory cleaning device.

The purpose of the invention is to reduce the dimensions of the combine.

In FIG. 1 shows a combine harvester with an axial threshing apparatus and its working units located in the direction of movement; . 2 - supporting frame, side view; in FIG. 3 - the same, top view; FIG. 4 is a section AA in FIG. 2.

The harvested material enters from the harvesting part 1 through the shaft 2 onto the threshing apparatus 3 located in the longitudinal direction of the machine, increasing against the direction of movement of the combine harvester. From the threshing drum 3 threshed straw through the ejection 4 is thrown into the field. Separated grains, together with a mixture of straw scraps, mucks and various impurities, fall onto a stepped bottom of the bismater on a cleaning device with pumping sieves 6, consisting of upper sieves 7, lower sieves 8 and blower 9. The impurities, the machine and straw trimmers are removed from the cleaning device to the field, and the threshed grain through the screw conveyor 10 and the elevator 11 receives the grain hopper 12, from which the grain is sent through the unloading system 13 to the vehicle. The main frame of the machine is formed of lower longitudinal beams 14, 15 extending almost horizontally above the front axle 16 to the steered bridge 17 and forming the lower frames. The lower longitudinal beams 14, 15 in the area behind the driving wheels 18 and before the cleaning device with swinging screens 6 are interrupted in their straight line00

Nominal passage and front frame profiles are shifted down. The lateral connection of the frame profiles is carried out by the main plate 19, and additional reinforcement is provided by the stiffness fittings 20. Due to the bending thus formed in the region of the driving wheels 18, a reduced width of the main frame and; therefore, a smaller width of the feed channel corresponding to the area for the threshing apparatus 3, and in the area of the cleaning device b, a larger width is needed there. Connections between the front vertical strut 21 and the middle vertical strut 22 are made using spatially arranged beams 23 and 24, forming the upper one from the front of the frame. Other vertical and horizontal supporting elements lying in the same plane with the side frame in the area of the cleaning device with swinging screens 6 are used to accommodate individual structural groups, as well as work units, for example, grain hopper 12 and drive unit 25.

Claims (1)

The claims The bearing frame of an axial combine harvester with a swinging wind-sieve cleaning, containing the front and rear parts made of longitudinal and transverse beams, consisting of upper and lower owls, while the drive wheels of the combine are located on the front of the frame, and the wind-screen cleaning is on the back, and the width of the lower front of the front in the installation area of the drive wheels is less than the width of the rear of the frame, which is so that, in order to reduce the dimensions of the combine, the lower from the front of the frame is made in parallel beams installed at a distance less than the distance between the longitudinal beams of the rear part and connected with them by scarves, and the upper one from the front part is made in the form of beams located at an angle to the longitudinal beams of the Lower base and at an angle to each other.
