FIELD OF THE INVENTION The invention relates to agricultural machine building, namely to automation equipment for grain elevators.

A device for centralized control of a grain elevator is known, comprising communication units interconnected with respective guide feeding and conveying mechanisms 1.

However, this device consists of complex interconnects, and this requires the creation in each case of an individual structural diagram, which determines the presence of long electrical connections, which does not ensure, if necessary, the independent adjustment of each actuator during the movement of grain along the route.

The purpose of the invention is to simplify the design of the device and increase the reliability of its operation.

The goal is achieved due to the fact that the route setting unit, the mixture composition setting unit and the discharge position setting unit are inserted into the device, the inputs of the communication units are connected to the outputs of the route setting unit, the discharge position setting unit, the feed and transport mechanisms, and the outputs of the communication units are connected to the inputs of the route setting unit, the mixture composition setting unit, guiding, driving and transporting mechanisms. FIG. 1 is a block diagram of the device; in fig. 2 - its functional scheme.

The device for centralized control of lazer grain elevator consists of a block 1 setting marchrutov, block 2 communication, block 3 setting the composition of the mixture and block 4 setting the discharge position.

The unit 1 for setting marches contains a set of links 5-11, respectively, duplicating the position of the norias 12, the fans 13 and through the blocks 2 of the communication of the conveyors 14, the fans 15, the reversing valves 16, the rotary tube 17 and the supply valves 18. In addition, the block 1 setting 20 has a Start button 19, starting node 20, Stop 21 button, setting valve 22 opening degree, switches for starting and ending points of the route, respectively, 23 and 24. The mixture setting unit 3 contains group 25 and individual setting 26 settings for sub-landing level dvizhek 27. The position specifying unit 4 has razruzki trolley control unit 28, the trolley 29 positions are determined setter 30, and the valve position on the carriage - setter 31. The device operates as follows. The switches 23 and 24 of the unit 1 set the routes to set the start and end points of the routes; through the communication units 2 to the redundant links 6, 8, 9, 10 and II of the unit 1 the routes connect the conveyors 14, fans 15, check valves 16 and feed gate valves. The number of blocks 1 of the assignment of the Routes is determined by the presence of elevators 15 12, which can operate simultaneously. The route is started in the following sequence. When the button 19 is pressed, a warning signal is issued and the start time of the start node 20 begins. After the time setting has expired, the start node 20 issues commands to the backup links 7-10, which are interconnected with the fans 2, flip valves 16, rotary pipe 17 and are directly connected to the fans 13. As a result of this element, the devices take up the desired position and the fans 13 and 15 begin to work. After the completion of these operations, the starting node 20 outputs a redundant link 5, interconnected link 12, and link 6, interconnected through blocks 2 of communication with conveyors 14, the command to start transport vehicles. The setting device 22 determines the opening degree 35 through the redundant link 11 interconnected with the supply gate valve 18. Before stopping the route, the supply valve 18 is closed, which is achieved by setting the valve opening degree 22 to the appropriate position of the setpoint adjuster. After the grain has been removed from the transport vehicles, the button 21 sends a command to stop them - Noria 12 and through the communication units 2 of the conveyors 14. After the transport vehicles stop, the fans 13 and 15 continue to work 45 for another 2-3 minutes to remove dust, and then automatically off. Switching off the fans can be substantially repeated by pressing button 21. When transporting grain from silos 27 before starting the route, block 3 sets the composition with the help of individual setting devices 26 selects valves to be controlled and sets the degree of their opening. The command is executed after the completion of the route start. The degree of opening can be adjusted for each valve by individual setting devices 26 or all valves at the same time by group setting 25. When using a self-propelled drop car 29 in the route before starting the route using setting position 30, the unit 4 sets the discharge position, the truck 29 is set to the desired position, and the reversing valve occupies the position determined by the setting device 31. The device for centralized control of the grain elevator allows creating such a system of blocks, the scheme of which depends From the elevator circuit, increase the reliability of the device operation by using unified units and industrial installation of the entire system, reduce inter-unit communications, improve transport equipment performance, cable and electricity consumption, Formula of the invention A device for centralized control of grain elevator, containing communication units, interconnected with appropriate guiding, feeding and transporting mechanisms, characterized in that, in order to simplify the circuit and increase reliability work, the unit specifies the routes, the unit specifies the composition of the mixture and the unit specifying the unloading position, the inputs of the communication units are connected to the outputs of the unit specifying the routes, the unit specifying the unloading position, guides the feeding and transporting mechanisms, and the outputs of the communication units are connected to the inputs of the unit for specifying the routes, the unit for specifying the composition of the mixture, the guiding, feeding and transporting mechanisms.
