Description

The invention relates to agricultural machinery, mainly to the harvesting of grain crops and non-grain parts of the crop.

Known technical solution combine straight-through grain harvester differs in that it is equipped with a bale chamber for forming a straw roll, and two rollers with eccentric, exciting and prepressing straw are installed at the drum output before entering the bale chamber (see KubGAU scientific journal No. 104 (10 ), 2014, http://ej.kubagro.ru/2014/10/pdf1032.pdf).

A disadvantage of the known device is low, performance as the threshing and separating apparatus has a low throughput due to the presence of broken and screw surfaces including directed towards each other with the same constant pitch along the length of the drum, the complex design of the threshing and separating apparatus requires high-tech manufacturing work at speeds of 600-800 min ^-1 , the design-technological layout of the bale chamber causes the creation of uncompensated torsion and bending moments that occur when the threshing and separation apparatus and the bale chamber are working simultaneously, which requires an increase in structural strength and as a result of the metal intensity of the unit.

Known stacker combine harvester, containing containing split housing from 2 parts forming the pressing chamber with the loading window located at the gathering straw separator, the feed conveyor between the threshing body and the hopper, unloading mechanism consisting of power cylinders, the rods of which are connected to the housing (see copyright certificate number 1563627 A1 class A01D 41/12, 41/02 publ. 15.05.90 (Bull. No. 18).

A disadvantage of the known device is a long time of formation and unloading of the roll, the high intensity of the structure and operating costs.

Known harvesting machine, including a header, a housing with a threshing device and an air-sieve cleaning system with a drive (see RF patent №2286045 C2, CL A01D 91/04, A01D 41/00, A01D 41/02, publ. 27.10.2006. Bull. №30 - prototype).

A disadvantage of the known devices is low operational reliability due to a complex design and technological scheme, increased metal consumption, loss of the stalk mass of the crop and an increase in its humidity, as well as clogging of the field with weed seeds of vegetation.

The technical result of the invention is to reduce energy consumption and expand technological capabilities.

The technical result is achieved by the fact that in the harvesting machine comprising a header, a threshing device body, an air-sieve cleaning system with a drive according to the invention, the rear part of the threshing device body is equipped for collecting straw, chaff and weed seeds by a collecting chamber with a folding lid, at the same time, the accumulation chamber has rotating sidewalls with dies, one of which is mounted on a shaft with a drive and a flywheel, and the other on an axis with a pressure device in the form of a spring and has a kine a mathematical connection with a hinged lid for its control, with the drive with the flywheel communicating with the drive of the air-sieve cleaning system via a belt drive.

The novelty of the proposed technical solution is due to the fact that energy consumption is reduced and technological possibilities are expanded due to the fact that the straw after its cleaning on the straw walker enters the storage chamber, which is mounted on the thresher body, and the chaff and weed seeds get into it. The accumulated mass is wound into a roll, after filling the accumulation chamber, the roll is loaded into a cart or remains on the field.

The invention is illustrated in the drawing, where in FIG. 1 shows a general view of the harvesting machine; in fig. 2 - section A-A, in FIG. 3 - view B.

The harvesting machine 1 (Fig. 1) consists of a header 2 (Fig. 1), a body of the threshing device 3 (Fig. 1), an air-sieve cleaning system 4 (Fig. 1) with a drive 5 (Fig. 1). The rear part of the housing of the threshing device 3 (Fig. 1) is equipped for collecting straw, chaff and weed seeds by an accumulation chamber 6 (Fig. 1) with a hinged lid 7 (Fig. 1), while the accumulating chamber has rotating side walls with combs 8 ( Fig. 2), one of which is mounted on the shaft 9 (Fig. 2) with the actuator 10 (Fig. 2) and the flywheel 11 (Fig. 2), and the other on the axis 12 (Fig. 2) with a clamping device in the form of a spring 13 (FIG. 2) and has a kinematic connection 14 (FIG. 3) with a hinged lid 7 (FIG. 1) for its control, and the drive 10 (FIG. 2) with the flywheel 11 (FIG. 2) communicates with driven by an air-sieve cleaning system 5 (Fig. 1) via a belt drive 15 (Fig. 1).

Combine 1 (Fig. 1) works as follows.

The grain mass is mowed by the header 2 (Fig. 1), which is threshed in the case of the threshing device 3 (Fig. 1) and divided into streams, containing an actuator 5 (Fig. 1) in an air-sieve cleaning system 4 (Fig. 1). After separation of grain residues from it in an air-sieve cleaning system 4 (Fig. 1), the straw is fed to a collection chamber 6 (Fig. 1) containing a hinged cover 7 (Fig. 1), which is mounted on the body of the threshing device 3 (Fig. 1 ), the chaff and weed seeds also go there. The mass as it is filled with the accumulation chamber 6 (Fig. 1) is captured by the rotating sidewall with the comb 8 (Fig. 2). It is mounted on the shaft 9 (Fig. 2) and is connected to the drive 10 (Fig. 2) and the flywheel 11 (Fig. 2), which ensures a stable process of work. When forming a roll of straw and chaff, it presses against the sidewall with dies 8 (Fig. 2) fixed on the axis 12 (Fig. 2) of the surface, which contains slots (not shown in the figure). In turn, the sidewall 8 (Fig. 2) fixed on the axis 12 (Fig. 2) presses the roll by means of a clamping device in the form of a spring 13 (Fig. 2), thereby ensuring the density of the roll to be wound. The unloading of the formed roll is carried out through a folding cover 7 (FIG. 1). In this case, the response pressure from the roll to the sidewall 8 (Fig. 2) fixed on the axis 12 (Fig. 2) overcomes the force from the pressure device in the form of a spring 13 (Fig. 2) moves the sidewall with the dies 8 (Fig. 2) and the axis 12 (Fig. 2) to engage with elements of the kinematic connection 14 (Fig. 3). Thus, torque is transmitted from the actuator 5 (Fig. 1) of the air-sieve cleaning system 4 (Fig. 1) through the belt drive 15 (Fig. 1), shaft 9 (Fig. 2), sidewalls with dies 8 (Fig. 1). 2) and the formed roll acting on the hinged cover 7 (Fig. 1), which opens and the roll falls on the field or loaded into the trailer (not shown conventionally in the drawing). Then the lid under its weight closes and the process of forming the roll is repeated.
