The invention relates to agriculture, namely, the system of automatic protection and control of self-propelled multisupport sprinkling machines.

Known hydraulic system emergency protection multisupport sprinkler comprising a stop valve with hydraulic actuator on the input of the machine controlled hydrocele, the tube running through all the supports and connected to the control unit hydrocele, and through a narrowing device for pressure piping, actuators with position sensors supports mounted on the housings and terminals synchronization mechanism intermediate the supporting trucks, the hydraulically operated valve located in the supply line of the hydraulic drive last truck and hydraulically connected with tube management (A.S. 1029921, CL A01G 25/16; A.S. 1521403, CL A01G 25/16; A.S. 1412663, CL A01G 25/16; A.S. 1304786, CL A01G 25/09; A.S. 1009344, CL A01G 25/09; patent 2208310, CL A01G 25/16; analogues).

The disadvantage of these designs is the complexity of the structural design actuators emergency protection, consisting of a large number of details: the Executive of the valve spring pendulum with a copy placed in the casing of the synchronization mechanism, position sensors supports. As a result, the failure of one node or component leads to decrease in the reliability of either a complete failure of the protection system is in General. Implementation of the Executive valves of non-ferrous metal leads not only to an appreciation of design, but also to theft in connection with the operation of the machine becomes difficult in automatic mode. In addition, during power outage, in the case of reverse bias pressure of the pipeline is emptying of the flow tube from the water, and therefore filled the air does not provide for automatic start working machine at work when you start pumping station.

All it says about the low reliability of the considered structures and requires the resolution of any deficiencies noted.

Well-known the other of the hydraulic system of emergency protection multisupport sprinkler comprising a stop valve with hydraulic actuator on the input of the machine managed hydrocele connected with a tube running through all the supports and connected to the pipeline end of the machine through a check valve and an adjustable choke, sequentially installed on the tube control the Executive valves, interacting with position sensor supports, hydraulically operated valve connecting the pipe with the pipe control actuator which is in communication with the upper cavity of the hydraulic shut-off organ, and before governors Executive valves on the tube control the means set normally open shut-off valves (A.S. 1386116, CL A01G 25/16; prototype).

Major drawbacks are the complexity of the structural design actuators and low reliability.

The technical problem of the invention is to simplify the design and increase reliability.

This object is achieved in that the actuators are connected to the input fittings with tube management through a normally open shut-off valve with tee, and the output is with the atmosphere, and the position sensors supports are made in the form of plates of the fluorine-containing plastic, having a slot with expanding the size of its ends attached to the shaft of the timing mechanism with bolt connection and the ability to move along the rod axis, and the slit is placed silicone tube coupled to the inlet and outlet fittings rigidly mounted in the casing synchronization mechanism intermediate supports, besides hydraulic connection orifice with pressure pipe is through the check valve.

Thanks to the new relationship actuators security systems, entrance fittings with tube management through a normally open shut-off valves with the tee and the output with the atmosphere, i.e. actuators associated with tube management at their computers the flax connect, whereas in the analog and the prototype actuators mounted directly in-line tube management, which binds them in a consistent way, there is possibility in the proposed solution significantly simplify the design of control devices, reducing the number of parts and components in comparison with analogues and prototype.

The design of the encoders supports in the form of plates of the fluorine-containing plastic, having a slot with expanding the size of its ends attached to the shaft of the timing mechanism with bolt connection and the ability to move along the axis of the rod, allows not only to exclude the nodes and details on each truck (two stops, spring pendulum with copier), but will simplify the operation for setting up system security alarms in comparison with analogues and prototype.

Placement of a silicone tube connected to the inlet and outlet nozzles rigidly mounted in the casing synchronization mechanism intermediate supports can eliminate complex and expensive item - Executive valve used in the models and the prototype.

Hydraulic connection orifice with pressure pipe through the check valve will significantly increase the reliability of the system when you stop pumping the article is ncii during re-start, providing reliability automatic start working machines in work that cannot be avoided no analogues either in the prototype when the reverse bias of the pumping station.

Thus, a new relationship and relative positions of components and parts, as well as a new design of individual elements will allow you in comparison with analogues and prototype to get a new positive effect of simplifying the design and improving the reliability of the hydraulic system of emergency protection multisupport sprinkler.

The hydraulic system of emergency protection multisupport sprinkler includes a stop valve 1 hydraulic 2 at the entrance of the machine, managed hydrocele 3, connected to the tube control 4, passing through all the supports and connected to the control unit 5 hydrocele 3, and through a narrowing device 6 to the pressure pipe 7, valve 8, a normally open shut-off valves 9 and actuating devices 10 with sensors 11 provision of supports mounted on the housings 12 and rods 13 synchronization mechanism intermediate the supporting trucks, hydraulically operated valve 14, fitted the config in the supply line of the hydraulic actuator 15 of the last truck and hydraulically connected with tube management 4, actuating devices 10 associated input socket 16 with the tube 4 through the normally open shut-off valve 9 with the tee and the output 17 from the atmosphere, the sensors 11 position supports are made in the form of plates of the fluorine-containing plastic, having a slot 18 with expanding the size of its ends fixed to the rods 13 synchronization mechanism using a screw connection 19 and can move along the axis of the rod 13, and the slit 18 posted by silicone tube 20, coupled to the input 16 and output 17 fittings rigidly mounted in the casing 12 of the synchronization mechanism intermediate supports, in addition, a hydraulic connection tapering device 6 with the pressure pipe 7 through the check valve 8.

The hydraulic system of emergency protection multisupport sprinkler operates as follows.

When the emergency situation on the intermediate support carriage is offset from the rod 13 of the synchronization forward or back (gap, ahead of the truck). As a result of this silicone tube 20, sliding in the slots 18, gets into an enlarged space at the end of the slot 18, which leads to depressurization of the pressure coming from the tube 4 through the open valve 9, and the connection with the atmosphere.

This causes the PA is giving pressure in the tube 4 and the closure of the hydraulically operated valve 14. The machine stops, excluding further curvature of the water conveyance belt and damage to the machine.

Simultaneously with the stopping of the machine actuates the control unit 5 hydrocele 3, causing closing of the valve body 1 by means of hydraulic drive 2 at the time, excluding hydraulic shock in the pressure line 7.

After Troubleshooting truck operator moves the valve 9 on the truck, in the "closed"position. This provides a pressure rise in the tube 4, the opening hydraulically operated valve 14 and the switching control unit 5 hydrocele 3.

As a result, the valve 1 by means of hydraulic drive 2 produces a smooth opening and filling water water conveyance pipeline machines. The machine starts to work.

As the operation of the machine is balanced emergency trolley relative to the longitudinal axis of the pipeline of the machine. This moves the rod 13 of the synchronization mechanism in the initial position, and therefore the silicone tube 20 is returned from the extended portion of the slot 18 in its narrow part that causes it to overlap, i.e. its relationship with the atmosphere ceases.

After aligning the longitudinal axis of the pipeline of the machine operator moves the valve 9 in the "open"position. The machine continues to work in automatic mode.

When you stop pumping station due to RA is to the displacement of the check valve 8 pressure between 7 pipeline and narrowing device 8, the outflow of water from the tube 4 is excluded, even when the reverse bias pressure network that provides after switching on the pump station smooth filling machine water (without hydraulic shock) and automatic inclusion in the work.

The use of the proposed solution will reduce the cost of protection set by 5-10%, increase reliability by 10-15%.
