(57) Abstract:

Use: agriculture, namely in irrigation technology under irrigation mnogomernymi by sprinkling a circular action. The inventive sprinkling machine includes a stationary support 1 fixed pipe 2 and the swivel elbow 3 which is connected to the discharge pipe 4, equipped with a sprinkler apparatus and placed on self-propelled trucks, the latter of which is equipped with a crane-unit 13 of the speed of movement of the machine associated with the program device to change the speed of car with fixed tube 2 disk 5, the body of which is made the guide groove 6, reflecting back the profile field on the front of the machine movement, and control valve 8 mounted on the swivel elbow 3, provided with a stem 7, interacting with the guide groove 6, the machine is equipped with a system of hydronamic with the control tube 12 connected to the actuator 11 of the hydraulically operated valve 10, which is communicated with the discharge pipe 9 and through the control valve 8 with valve-point 13 speed machine, made in the form of hydraulically operated valve installed in the supply line 14 g which relates to agriculture, namely, irrigation technology, and can be used when watering multisupport by sprinkling circular steps.

Known sprinkling machine that contains the pipeline, installed on trucks with hydraulic drive. Each plumbing pipe alternately installed in pairs sprinkler devices equipped with shut-off valves. On the fixed bearing set ring with supports that can interact with the control valves. A control valve connected to hydrocele and valve-a valve that is connected to two reservoirs management. Sprinkling machine works in three versions with flow rates Q of 0.5 Q and 0.25 Q due to the automatic switching hydrocele and set or clear emphasis on the ring. The disadvantage of this codevalues machine is the lack of regulation, irrigation rates (the speed of movement of the machine) subject to the contours of the ground at the front of the machine, resulting in waterlogging of soil, water logging, recovery of groundwater levels in low places (the beams) field. In addition, this solution may not exclude damage to machine failure hydrosulfite, which entails a high labor costs associated with rehabilitation of irrigation technology, CH the spine.

Known for another sprinkling machine. consisting of the fixed bearing and pipe with sprinkler devices installed on self-propelled trucks with hydraulic drives. On the last carriage has a control unit with crane-unit speed machines. The control unit is equipped with a control wheel with adjustable plates. The control wheel kinematically connected to the wheel last truck, and adjustable plate by means of a rack and pinion mechanism with the crane-unit speed machines. While rotating the wheel of the machine rotates the control wheel. This adjustable plate by means of a rack and pinion mechanism interact with the crane-unit speed machine and it automatically changes the rate of irrigation. The disadvantage of this sprinkler is structural complexity (reducer, chain drive, a rack and pinion mechanism, and so on) and low reliability because the presence of the kinematic connection of the gear wheel and rack and pinion mechanisms at work in the environment with increased humidity will cause intense korrodirovaniju and as a result of the meeting, failure. In addition, this decision has low accuracy varying the speed of movement of the machine in the AC control is relatively low (high) area of the field or area with a high groundwater level (so that is, is out of sync with the control unit with a specific profile fields), no stop last truck when the alarm protection system causes damage to machine failure hydrosulfite that reduces the reliability of the machine.

The purpose of the invention to simplify the construction, increase reliability and extend the functionality of the work. This objective is achieved in that the programming device has a fixed tube drive, the body of which is made the guide groove, reflecting back the profile field on the front of the machine movement, and a regulating valve mounted on the swivel elbow and provided with a stem, vzaimodeistvuyuschim with the guide groove, the machine is equipped with a system of hydronamic with the control tube connected with the drive hydraulically operated valve, which is communicated with the discharge pipe and through the control valve, with the valve-unit speed machines, made in the form of a hydraulically operated valve, installed in the supply line of the hydraulic drive past the truck and having adjustable drainage hole.

Thanks to the supply of machines software device having mounted on NEPAD the movement is ensured in comparison with the base (prototype) higher accuracy varying the speed of movement of the machine depending on the terrain (ground water level) because of eliminates the offset control unit relative decrease (increase) of the area of the field or area with a high groundwater level when the wheels are slipping, the last truck. In addition, the proposed solution compared to the baseline (prototype) excludes gear (gearbox), the kinematic relationship (chain transfer), known in the prototype that will prevent failures and improve reliability of the machine.

Due to the presence of a regulating valve mounted on the swivel elbow and provided with a stem that communicates with the guide groove, and also supply machine system hydronamic with the control tube and the connection control valve with pressure pipe, the drive of which is communicated through the control tube system hydronamic with faucet knobs speed machine, made in the form of hydraulically operated valve installed in the supply line of the hydraulic drive past the truck and having adjustable drainage hole, provided the exception of a rack and pinion mechanism which during operation of the machine in a high humidity causes frequent failures (lock-up), that will significantly increase reliability and simplify const functionality sprinkler and increase reliability in its work.

In Fig. 1 schematically illustrates sprinkling machine; Fig. 2 software the device is made in the form of a disk, in a body which has a guide groove, reflecting the profile of the field in front of the machine (top view), and Fig. 3 - scan software of the device along section 4.

Sprinkling machine includes a stationary support 1 fixed pipe 2, swivel elbow 3 connecting pipe 4, the software device in the form of a disk 5 in his circle, has a guide groove 6, reflecting back the profile field on the front of the machine. In the guide groove 6 posted by rod 7 of the regulating valve 8, which interacts with its surface reflecting back the profile field on the front of the machine. The control valve 8 is fixedly mounted on the swivel elbow 3 and hydraulically connected to pressure pipe 9, through hydraulically operated valve 10, the hydraulic actuator 11 which is connected with the hydraulic system of protection through the control tube 12, the valve-unit 13 of the speed of the machine is made in the form of a hydraulically operated valve installed in the supply line 14 of the hydraulic actuator 15 of the last truck. The hydraulic actuator 16 of the crane unit 13 is provided with a drain hole 17, in the line that is the same machine on the field of the fixed tube 2 is set and adjusted by the relief field software device made in the form of a disk 5 with the guide groove 6, reflecting back the relief of this irrigated fields. After adjusting disc 5 is rigidly fixed to the fixed tube 2 and the operator sprinkling machine is the machine is started, resulting in the rise of pressure in the control pipe 12 of the protection system, which causes the opening Gidropress valve 10 by means of the hydraulic actuator 11, and the water from the discharge pipe 19 is fed through a control valve 8 in the hydraulic actuator 17 of the crane unit 13 of the last trolley car. The crane unit 13 is opened, providing a supply of water from the pipeline 4 cars in the hydraulic actuator 15 of the last truck, causing the machine starts to move. The operator sets the specified irrigation rate with the adjustment of the valve 18, thus reducing or increasing the outflow of water from the hydraulic actuator 16 through the vent hole 17. By the fall or rise of pressure in the hydraulic actuator 16 closing element of the valve-point 13 speed decreases or increases the flow entering the hydraulic actuator 15 of the last truck, allowing for a certain speed of movement of the machine corresponding to the given norm of irrigation, i.e., a constant outflow of water through the drain opening 17 provides for obtaining a constant preset RMS is) automatically depending on the contours of the ground at the front of the machine as follows.

Movement of the machine causes the rotation of the rotary knee 3 around the stationary support 1 and the fixed tube 2. In the result of which is rigidly fixed on the swivel elbow 3 control valve 8, rotating the rotary knee 3, communicates with the piston rod 7 with the guide groove 6 of the disk 5 software device, reflecting the inverse topography of the field. The roughness of the relief reflected in the groove 6 of the disk 5 software device perceives the rod 7, which is moving up or down changes the flow of water to the hydraulic actuator 16 of the crane unit 13 that is, due to the constant outflow of water from the drain port 17 via a regulating valve 18, the rise or fall of pressure in the hydraulic actuator 16 of the crane unit 13 of the speed of movement of the machine, and this will entail a change of driving speed (normal irrigation). Moreover, in connection with the reflection of the back of the elevation profile fields in the groove 6 will be increasing speed sprinkling machines, and hence the reduction of irrigation in areas of lower relief of the field, and in places of rising terrain reduction of driving speed and increased irrigation.

When the emergency situation machine proishodit to the pressure drop in the hydraulic actuator 11 and the closure of the hydraulically operated valve 10.

In this regard, is the termination of a supply of water from the discharge pipe 9 to the control valve 8 in the hydraulic actuator 16 of the crane unit 13. The constant outflow of the hydraulic actuator 16 of the crane unit 13 through a drain hole 17 of the adjusting valve 18 causes a drop in pressure in the hydraulic actuator 16 and the blocking of the locking element of the crane unit 13. Water supply to the hydraulic actuator 15 last truck stops, causing it to stop. This results in stopping the whole machine, which prevents further bending of pipe 4 cars and machinery breakdown failure hydrosulfite.

We offer sprinkler machine will allow you in comparison with baseline (prototype) to improve the uniformity of the distribution of irrigation water in the irrigated field, eliminate waterlogging in low areas of the field, will reduce the rise in groundwater levels.

In addition, extended functionality compared to the baseline (prototype), since no damage to machine failure heroeswiki.

Generally, the proposed technical solution is pivot - inherent simplicity of design, reliability, and expansion capabilities.
