The invention relates to agriculture and can be used in irrigation techniques, namely sprinkling machines, moving around the Central support.
Known sprinkling machine circular steps, which includes water conveyance pipeline sprinkler devices, placed on trucks with hydraulic cylinders (see Krakovets V.M., Nikulin SR operator Handbook "Frigate" and "Volzhanka", M, ear, 1976, analog).
A disadvantage of the known machine is that it performs a circular motion around the fixed bearing only clockwise; that does not allow its use in fields with complex configuration where it is impossible rationally to write them in a circle, and prevents the placement under one of the machines a few crops with significantly different frequency of watering.
Also known sprinkling machine, comprising a stationary support, a self-propelled truck with hydraulic cylinders, water conveyance pipeline sprinkler apparatus, in which to implement the reverse movement of water served alternately in the upper and lower hollow cylinders, and change the design of the system controlling the speed of movement of the trolleys (Koshkin NM, Nagorno VA, Gordienko, V.V. Fomin, " GI "Frigate" with reversing course and possibilities of its practical application" W. "elaorate and water management", 2002, No. 4, prototype)
The disadvantage of this sprinkler is substantial complexity and cost, and lack of reliability.
An object of the invention is the provision of a reversing movement, simplifying the design and improving the reliability of the sprinkler.
This task is achieved by the fact that on the power lever trucks fixed arms, tappets fitted with dual tips, and main wheel brakes are welded additional brake with a Central angle 125°and each of the trucks (except the last) is provided with an additional speed control system hydraulic emergency protection, located symmetrically to the main speed controller with respect to the pipeline, each of which connects the output of the pressure sleeve through the ball valve with the hydraulic cylinder, and the inlet pressure sleeve - water conveyance pipeline.
The difference between this pivot from the prototype is that it comes with additional brackets power lever, brakes and speed controllers with hydraulic emergency protection, as well as coupled ends of the plungers. Depending on the direction, the operator connects the respective plungers, brakes and speed controllers. This is substantial it is easier to design sprinkler reverse movement, increases the reliability of its work and decreases the cost of upgrading existing sprinkler machines.
Figure 1 shows a General view of the pivot. Figure 2 shows a self-propelled trolley reverse pivot. Figure 3 shows the location of the primary and secondary speed controllers (top view).
Sprinkling machine (figure 1) consists of a stationary support 1, self-propelled trucks 2 cylinders 3 and water conveyance pipeline 4 with sprinkler apparatus 5. On the power lever 6 (2) truck 2 is fixed to the bracket 7. The lugs 8 and 9 are front and rear plungers 10 and 11 provided with additional lugs 12 and 13. The stoppers 14 and 15 of the wheels 16 is equipped with primary and secondary brakes 17 and 18 and springs 19. Moreover, the Central angle between the primary and secondary brakes 125°. Cart 2 (except the last) set the primary and secondary speed controllers 20 and 21 (figure 3), which with the help of rods 22 and 23 are connected with the water conveyance pipeline 4. The water inlet from the water supply pipe 4, the speed controller 20 and 21 is carried out through the input pressure hoses 24 and 25. For inclusion in the core 20 and an additional 21 speed controller use ball valves 26 and 27 which connect the output pressure hoses 28 and 29 to the hydraulic cylinder 3. N the cart 2 installed additional guides 30 and 31. On the primary and secondary speed controllers 20 and 21 are mounted to the Executive valves 32 and 33 with the tubes 34 and 35 of the hydraulic emergency protection.
The machine operates as follows. When driving clockwise water under pressure is supplied through the stationary support 1 in water conveyance pipeline 4, the self-propelled truck 2 and sprinkler apparatus 5.
Through the inlet of the pressure sleeve 24 and 25 water flows in the primary and secondary speed controllers 20 and 21. The ball valve 27 additional regulator 21 is closed and the ball valve 26 of the main speed controller 20 is opened, and water through an outlet delivery hose 28 is supplied to the hydraulic cylinder 3. The plungers 10 and 11 installed on the power lever 6 and the lifting cylinder 3 move the wheel 16 and the trolley 2 forward. The main brake 17 of the stoppers 14 and 15 is pressed by the spring 19 to the wheel 16 and stoparic cart 2 at idle cylinder 3. The machine rotates around the fixed bearing 1 clockwise and performing irrigation field irrigation apparatus 5. Trouble-free operation of sprinkler provide Executive valves 32 and hydraulic tubing 34 emergency protection basic speed controllers 20.
In order sprinkling machine changed direction and began to rotate in a counterclockwise direction, the machine operator must install the front the rear plungers 10 and 11 on the bracket 7. While the rear pusher 11 turns 180° and the tip 13 is mounted on the wheel 16. The plunger 11 is placed in the upper rail 31. At the front of the plunger 10, the tip 12 is removed and after a turn of 180° again mounted on the plunger 10, which is mounted at one end on the bracket 7, and the other on the wheel 16. The plunger 10 is placed in the guide 30. Additional brake 18 by means of springs 19 are pressed against the wheel 16, and the main brake 17 in this position departs from the wheel 16. The ball valve 26 is closed and the ball valve 27 on the contrary is opened, the water in the cylinder 3 is supplied via the output pressure sleeve 29 and the additional speed controller 21. When the lifting cylinder 3, the plungers 10 and 11 move the trolley in the opposite direction and the car is moving counterclockwise. To ensure trouble-free operation the pivot operator disables the tube 34 hydronamic main speed controllers 20 and connects to the node powering hydraulic tube 35 additional speed controllers 21.
We offer sprinkler machine provides reverse movement clockwise and counterclockwise, after an appropriate permutation of the components and connections of the speed controllers. Moreover, the machine is characterized by simple design, lower cost and provide the supports increasing reliability. Sprinkling machine saves water and energy resources when grown under the same machine multiple crops with different timing of irrigation or one culture for different needs (green forage, hay or seeds). This excludes additional passages for individual sectors of the field. In addition, sprinkling machine can improve the survival rate of seedlings of vegetable crops in the early period of growth by improving the water regime of the soil. Reverse sprinkling machine eliminates watering sectors of the field with a similar level of groundwater. Can be improved irrigation technologies irrigated areas with complex topography and soils of low permeability, through fractional watering small norms. Reverse sprinkling machine will allow you to irrigate non-standard sections, such as pie and rectangular, this increases the coefficient of land use. Additionally, this sprinkling machine allows the operator to lower labor and material costs and losses of agricultural products to align the car after accidental bending of the pipeline.
