Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry. The combine for harvesting sorghum comprises a self-propelled chassis with a trailer, a hopper, a header, and a conveyor for plants. On the self-propelled chassis a frame is mounted on which through the hydraulic hitch two or more modules are mounted. Each module comprises a direct flow remote threshing chamber, a normaliser, an intermediate conveyor and a synchronising transmission.

EFFECT: modules are located with the ability to change the distance between them, which provides harvesting of different types of sorghum with different size between rows.

Description

The invention relates to agricultural machinery, specifically to machines for harvesting sorghum.

Known harvester for harvesting sorghum broom (patent RU No. 2220531, IPC A01D 37/00, A01D 41/08, A01D 45/00. Combine for harvesting sorghum broom. Application No. 2002107188. Publish. 10.01.2004. Bull. No. 1). This combine is a header-sheaf binder consisting of a frame with a divider attached to it, a sectional conveyor, a grass separator, a cutting apparatus, a knitting apparatus, a needle conveyor, and a running gear. A straight-through external threshing chamber is installed on the front of the header-sheaf on a parallelogram hydraulic hitch, a sheaf conveyor and a tractor cart are attached to the rear of the sheaf-headers, a grain hopper is installed on top of the header-sheaf.

Also known is a combine for harvesting broom sorghum (A. Ryadnov. The harvester removes broom sorghum / A. Ryadnov, A. Skvortsov, R. Sharipov // Rural Machine Operator. - No. 7. - 2004. - p. 8-9). The harvester is a self-propelled chassis with a direct-flow external threshing chamber mounted on it, a hydraulic hitch, a hopper, a header, a plant conveyor and a trailer.

The direct-flow remote threshing chamber threshes the plants on the vine, collects and transports the grain to the hopper. The hydraulic hitch allows you to install a direct-flow remote threshing chamber to the required threshing height. The threshed plants emerging from the direct-flow external threshing chamber fall onto the header. The cutting height of the plants by the header is adjustable. Mowed plants under the influence of inertia are stacked on the plant conveyor and transported to the trailer. The speed of the conveyor belt is adjustable.

The disadvantage of this harvester is that at a low speed, the mowed plants, due to insufficient inertia, do not completely fit on the conveyor, which leads to the loss of plants due to grinding by the header.

Also known is a combine for harvesting industrial crops (patent RU No. 2421974, IPC A01D 41/08. Combine for harvesting industrial crops. Application No.2010100341. Pub. June 27, 2011. Bull. No. 18), taken by us for the prototype. The harvester contains a self-propelled chassis with a direct-flow external threshing chamber mounted on it, a hydraulic hitch, a hopper, a header, a plant conveyor, a trailer and a normalizer in the form of a chain-slat conveyor installed in front of the direct-flow threshing chamber.

The disadvantage of this combine is its low productivity.

The invention consists in the following.

The objective of the invention is to increase the working width of the harvester and ensuring the arrangement of the working bodies of the harvester in accordance with the distance between the rows of the harvested crop.

The technical result is an increase in productivity of the harvester when harvesting sorghum broom, sugar and grain.

The specified technical result during the implementation of the invention is achieved by the fact that a frame is mounted on the self-propelled chassis, on which two or more modules are mounted via a hydraulic hitch, including a direct-flow external threshing chamber, a normalizer, an intermediate conveyor and a synchronizing gear, and it is possible to change the distance between the modules. Combine harvesting of two or more rows of plants increases its productivity, and the ability to adjust the distance between the modules provides harvesting of sorghum of various species, which differ in the size of row spacing during sowing.

Figure 2 presents a diagram of the proposed combine for harvesting sorghum. View from above.

The harvester for harvesting sorghum is a self-propelled chassis 1, instead of which it is possible to use other energy means, including a tractor, a hydraulic hitch 2, a grain hopper 3, a header 4, a conveyor belt 5, a trailer 6. A frame 7 is attached to the self-propelled chassis 1 on which modules 8 are installed through the hydraulic hitch 2, each of which includes a direct-flow external threshing chamber 9, a normalizer 10, an intermediate conveyor 11 and a synchronizing gear 12. The hydraulic hitch 2 can be made but as common to all the modules 8, and individual to each. To reduce losses of cut plants when loading them into the trailer 6, the sides 13 are installed on the plant conveyor 5. In order to coordinate the linear speeds of the strips of the normalizer 10, the intermediate conveyor 11 and the combine, a synchronizing gear 12 is installed, which can be either mechanical, hydromechanical, or electromechanical, or electronically controlled.

The normalizer 10 and the intermediate conveyor 11 can be either chain-slatted, or tape, or screw.

The harvester for harvesting sorghum works as follows. Before the start of harvesting, the distance between the modules 8 is set equal to D - the value of row spacing during sowing. Direct-flow remote threshing chamber 9 of each module 8 threshes the plants on the vine, collects and transports the grain into the grain tank 3. The hydraulic linkage 2 allows the modules 8 to be installed at the required threshing height. The threshed plants, leaving the direct-flow external threshing chamber 9, are sent to the intermediate conveyor 11. The plants are picked up by the straps of the intermediate conveyor 11 and fed to the cutting apparatus of the header 4, cut and then laid by the intermediate conveyor 11 on the plant conveyor 5.

The synchronizing transmission 12 provides the necessary ratio of the linear speeds of the strips of the normalizer 10, the intermediate conveyor 11 and the combine regardless of its speed. The threshed and cut plants enter the trailer 6.
