The invention relates to agriculture, namely, self-propelled multisupport sprinkling machines with water from the penstocks.

Known self-propelled trolley multisupport sprinkler comprising a frame with a pair of supporting wheels, driven hydraulic unilateral actions, related through a distributor with an element of the synchronization system of machines, and through the slide and grips - lug wheels, and the slide made with a longitudinal groove and two located on the sides of the toothed rails, between which is mounted a gear train, the axis of the latter is connected with the synchronization system, and the wheels turn, depending on the direction of movement, one with one of the rails, and the other with the sector gear, a spring-loaded to the frame and connected with the rod of the hydraulic cylinder (A.S. 552934, class A 01 G 25/09, similar).

The disadvantage of this truck is the design complexity due to the presence of a large number of parts and components, performing the reverse and simultaneous movement of trucks, large operating costs transfer machines on reverse, low reliability, as used in the design of gear units and parts, which when exposed to irrigation water will quickly fail and lead to failure of machines. In addition, you cannot use the standard components and parts for existing machines, that will lead to the development and establishment of production of these nodes manufacturers, testing technologies, thus will cause more, not a small cost and will increase the period of the introduction of these machines in production.

Known other self-propelled trolley multisupport sprinkler machine that contains a frame, supporting wheels with hydraulic drive connected through the valve and control valve element of the system synchronization, and the synchronization system is made in the form of a flexible cable that is installed on the fixed blocks attached to the pipeline of the machine with the formation of the diamond, small diagonal which is the regulating rod is made with two symmetrical Cams interacting with regulating valve and the dispenser is provided with outlet pipe, hydraulically connected with the lower cavity of the hydraulic actuator and a control valve (A.S. No. 114075, class A 01 G 25/09, prototype)

The disadvantage of this design is the low reliability, the complexity of manufacture and operation, no possibility of using standard units (produced by manufacturers when creating a reversible machine.

The technical problem of the invention is to improve work efficiency when translated into direct and reverse and create a unification of parts and components.

The put is fair task is achieved by that distribution block provided with an additional valve-a valve installed in the supply line of the lower cylinder cavity and connecting it alternately with the pipeline of the machine and the atmosphere, and water supply is carried out simultaneously in the primary and secondary distribution valve of the discharge pipe using a tee, while the piston has two sleeves with backing washers located on either side in the opposite direction to each other and placed on the upper part of the rod of the hydraulic cylinder in a sliding fit, limited in the lower position by the collar, and the top - tightening the nut, in addition, the piston rod of the cylinder is provided with a sealing element mounted in the lower part of the housing of the hydraulic cylinder, and the valve stem of the valve and the additional valve stem valve connected to the lower parts of the threaded connection with the sleeve, the lug is made in the form of a hollow square with oval-shaped work surfaces interacting with the tip forward and one reverse gears placed on the left and right side of the pushers in their beginning and United with them swivel, lockable for forward and reverse motion using the rear and front pegs.

The supply of distributed self-propelled unit p is versiunea truck additional valve distributor installed in the supply line of the lower cylinder cavity and connecting it alternately with the pipeline of the machine and the atmosphere while supplying the water simultaneously in the primary and secondary distribution valve of the discharge pipe using a tee, provides the use of commercially available domestic industry details of the nodes that were manufacturing test and showed high efficiency and reliability in the operation of the sprinkler machines. This allows for standardization (interchangeability) used in the invention components and parts, which eliminates the additional costs of developing and introducing new components and parts, speeds up the process of implementation of the invention in the production. These distinctive features are absent in the analog and the prototype.

The supply of the piston of the hydraulic drive two cuffs with supporting washers located on either side in the opposite direction to each other and placed on the upper part of the rod of the hydraulic cylinder in a sliding fit, limited in the lower position by the collar, and the top - tightening nut, allows not only to achieve the interchangeability of mass-produced parts, but also to ensure reliable and efficient operation in the reverse movement, i.e. creation efforts in raising and lowering hydrotrend is and with high efficiency, as it provides high integrity, eliminating the flow from the upper to the lower cavity, and Vice versa. All these positive qualities are missing in the famous prototype, and this is due to its low efficiency, resulting in certain moments the failures.

The supply rod hydraulic cylinder sealing element mounted in the lower part of the body of the cylinder, greatly increases efficiency when reverse motion of the cylinder, as in this case excluded the loss (leakage) of water from the lower cylinder cavity in comparison with the prototype. This ensures reliable and efficient operation when reversing the movement of vehicles. This characteristic either in the analog or in the prototype is not known.

The connection rod valve valve and the additional valve stem of the dispenser bottom threaded connection with the sleeve provides not only the efficiency of the distribution block in the reverse mode, i.e. with variable water flow in the upper and lower cavity and discharge it into the atmosphere, but also the ability to create unification and enforceability of mass-produced parts without additional development costs of new ones.

The implementation of the lug in the form of a hollow square with oval-shaped work surfaces that interact with the tip and the front and rear, ensures smooth sliding during the return of the pusher, which reduces the rapid attrition wear of the working surfaces, such as lugs and lug, which hung (failure) in the cylinder and stop the machine. This significantly increases the efficiency of reversible truck in comparison with analogue and prototype.

By placing the tips of the front and rear on the left and right side of the pushers in their beginning, and connect with them swivel, lockable for forward and reverse motion using the rear and front of the cotter pins, the effect of a previously unknown either in the analog or in the prototype - increase efficiency by reducing costs when translated from direct to reverse.
