Description

The claimed invention relates to agricultural machinery, in particular to the cabins of the combine, providing information for the operator on the status of the settings of the units of the combine (forage) combine, an indication of the state of the hydraulic, fuel systems and alarm systems in the operation of the combine systems.

To display information about the state of the on-board systems of the combine, information monitors are used. The most widely used are information monitors installed on the side stand of the cab or on the control panel of the combine aggregate settings. Known information monitors of this kind have the following disadvantages: the installation location of the information monitor in the cab is located on the edge of the operator’s field of view or goes beyond its borders, which does not allow the operator to respond in a timely manner to an emergency; the signs on the information monitor are small, which in the daytime of the combine makes it difficult to read information about the status of the combine units from the display; the need to lay electrical harnesses inside the rack, which leads to an increase in its dimensions and, as a result, worsens the overview of the working area in the area of the adapter and harvested mass on the field (Combine harvester self-propelled RSM-142 "Acros". - Operation and maintenance manual. - Rostov-on-Don: Rostselmash Combine Plant LLC, 2012).

The technical solution closest to the claimed invention is a combine harvester (forage harvester) (patent EP 2601827 A1, prior. 12/08/2011), which includes a cab that contains an information monitor mounted on the windshield and connected to the fixed part of the steering column using an electric harness, an armrest with a handle for controlling the combine located on the right side of the operator’s workstation, an aggregate control panel and a standard information monitor.

The disadvantages of the prototype are as follows: when reading readings from an information monitor located on the windshield of the cab, it is necessary to combine the operator’s eye with the information monitor through the hole in the steering wheel or lower the steering wheel below the information monitor, which complicates the adjustment of the position of the movable part of the steering column, the height of the workplace the operator to combine with the direction of the operator’s gaze, while the overview of the working area in the area of the adapter and the harvested mass on the field partially overlaps the body of the information monitor, which makes observation difficult; the number of parameters on the state of the combine systems displayed on the screen of the information monitor is limited; the presence of an open electric harness between the information monitor and the fixed part of the steering column, which can lead to its breakage during operation, and also worsens the aesthetic appearance of the cabin.

The purpose of the invention is the provision of information for the operator about the state of the onboard systems of the combine (fodder) harvester on the windshield from inside the cab without affecting the view of the working area in the area of the adapter and the harvested mass on the field and the operator's ability to select the displayed parameters.

This goal is achieved by the fact that in the cab of the combine containing the information monitor, control panel of the units, an armrest with the handle of the control of the combine located on the right side of the operator’s workstation, a parameter selection panel and a video projector are introduced, which are connected to the electrical outputs of the parameter selection panel by electrical inputs and the electrical inputs of the parameter selection panel are connected to the electrical outputs of the information monitor, which is connected by inputs to the outputs of the sensors of information about the state of the onboard systems of the combine, while information about the operation of the onboard systems of the combine from the optical output of the video projector is projected onto the inside of the windshield of the cabin, equipped with a reflective coating that provides indication of the specified parameters on the windshield. The choice of parameters displayed on the windshield is carried out by the operator using the parameter selection panel.

The list of information displayed contains data on the moisture content of the harvested grain, on losses occurring behind the combine, as well as on the fuel supply, engine, hydraulic system malfunctions and displays signs indicating the clogging of the main units: threshing drum, grain group, unloading system.

The video projector can be installed on a fixed part of the steering column, or on the inside of the roof, or on the rear wall of the cabin, while the video projector and the information displayed on the inside of the windshield do not overlap the view of the working area in the adapter area and the harvested mass on the field.

The invention is illustrated by drawings:

FIG. 1 - harvester, left view;

FIG. 2 - cab harvester, left view;

FIG. 3 - the windshield of the cabin, inside view;

FIG. 4 is a functional diagram of the output of information from the sensors of the combine to the windshield of the cabin of the combine.

The claimed device includes the following elements (Fig. 1-4): 1 - combine; 2 - a cabin with a roof 3 and an inner surface 4, floor 5 and rear wall 6; 7 - windshield; 8 - fixed part of the steering column; 9 - moving part of the steering column; 10 - a steering wheel; 11 - side stand; 12 - the operator’s chair with an armrest 13, a control handle 14 and a standard information monitor 15; 16 - video projector; 17 - the area of the reflective coating on the windshield 7; 18 - control panel units; 19 - sensors of the combine 1; 20 - remote control parameter selection, built-in standard information monitor 15.

The cab 2 of the combine 1 (see Fig. 1) consists of a roof 3, a rear wall 6, a windshield 7, struts 11 and a floor 5, on which an operator chair 12 is mounted with an armrest 13 fixed on it with a control handle 14, a standard information monitor 15 and the control panel of the units 18 (see Fig. 2, 3). In this case, the fixed part 8 of the steering column is rigidly fixed on the floor 5, to which, in turn, the movable part 9 of the steering column with the steering wheel 10 is fastened. The video projector 16 can be fixed motionless on the inner surface 4 of the cab 2, as well as on the fixed part 8 the steering column or on the rear wall 6. Information comes from the sensors 19 of the combine 1 to the information board 15 and then to the parameter selection panel 20. Using the parameter selection panel 20, the operator selects the necessary list of parameters that should be obrazheny on the windshield, and the information supplied to the video projector 16 and further projected onto the reflective coating 17 of the windshield 7.

The claimed device operates as follows. During the operation of the combine 1 (see Fig. 1), the operator must constantly keep under control the control system of the combine and at the same time do not take his eyes off the area of the harvesting unit and the harvested mass on the field. In this he is helped by the information displayed on the windshield 7 in the area with the applied reflective coating 17 (see Fig. 3, 4). At the same time, cabin 2 (see Fig. 2) consists of a roof 3, a rear wall 6, a windshield 7, struts 11, and floor 5. An operator’s chair 12 is installed on floor 5 with an armrest 13 fixed on it with a control handle 14 for adjusting the speed the harvester, a standard information monitor 15 with an integrated parameter selection panel 20, for displaying the main parameters of the harvester systems (see Figs. 2, 3), and the control panel of the units 18 (see Fig. 3). The fixed part 8 of the steering column is additionally rigidly attached to the floor 5, to which, in turn, the movable part of the steering column 9 is mounted, configured to change the angular position relative to the vertical by 45 degrees, which provides ease of adjustment for the operator. The steering wheel 10 is attached to the movable part 9 of the steering column (see Fig. 2, 3) to control the direction of movement of the combine 1.

To display information on the windshield 7 (see Fig. 3) in the area of the reflective coating 17 (see Fig. 3, 4), the video projector 16 can be placed motionless on the inner surface 4 or on the fixed part 8 of the steering column, or on the back wall 6 of the cab.

Information from the sensors 19 of the combine 1 goes to the information panel 15 and then to the remote control of the selection of parameters 20, with which the operator selects the parameters characterizing the harvesting process and the technical condition of the on-board systems of the combine, after which the selected information is transmitted to the video projector 16 and projected onto reflective coating 17 windshield 7.

The information displayed on the windshield contains, in particular, data on the moisture content of the harvested grain, losses incurred behind the combine, and if the permissible norms are exceeded according to these indicators, the operator will be able to adjust the units so that the combine does not experience increased loads. The displayed information also visually signals about malfunctions of the engine, hydraulic system and clogging of the main units: threshing drum, grain group, unloading system, which allows the operator to respond in a timely manner to emerging changes in operating conditions, which, ultimately, increases the service life of the combine.

The technical result consists in improving the operational properties and in increasing the reliability of the combine due to the prompt presentation of information about the condition of the on-board systems of the combine on the windshield (without taking the operator’s gaze from the harvesting area on the field and without blocking this area with the displayed information), which allows the operator to quickly respond emergency situation, as well as select the output parameters on the status of the harvester systems on the windshield of the cab during operation.
