Description

Technical Field

[0001] The invention belongs to the technical field of sprinkler irrigation devices, and in particular refers to a quantitative dosing device based on a reel-type sprinkler irrigation machine. Background Art

[0002] The working principle of the reel sprinkler mainly relies on the water turbine power drive system. Through the design of large cross-section and small pressure, a high recovery speed can be achieved at a very small flow rate. Specifically, the speed of the water turbine is transmitted to the reducer through the belt drive device. After the speed is reduced, the chain drive generates a large torque force to drive the winch to rotate, thereby realizing the automatic recovery of the PE pipe. At the same time, the high-pressure water flow flowing out of the water turbine is directly sent to the sprinkler through the PE pipe. The sprinkler evenly sprays the high-pressure water flow over the crops, which is scattered into fine water droplets that fall evenly and continue to spray as the PE pipe moves.

[0003] Generally, reel-type sprinkler irrigation machines are only used for sprinkler irrigation operations. In the prior art, pesticides are added to the connecting device in the PE pipe. Since the dilution of the pesticide particles is not sufficient, effective insecticide or feeding effects cannot be achieved, and the undissolved pesticide particles are easy to cause blockage of the PE pipe or the water outlet holes, causing erosion to the internal structure of the reel-type sprinkler irrigation machine. In order to avoid path duplication, the front walking part of the reel-type sprinkler irrigation machine should carry the pesticide or pesticide liquid synchronously, which is not convenient to carry, and it is also necessary to provide additional operating power for the pesticide or pesticide liquid to move synchronously with the front walking part.

The towing rope 2 56 passes through the hole 2 49 of the limiting disc 47 and is fixedly connected to the bottom of the sliding cylinder 50 .

[0044] When in use, the device of the present invention is connected to a power source, the driving motor 11 is connected to the power source and energized, the upper end of the main pipe body 42 is connected to the bottom of the pesticide dilution box, and the lower end of the hose pipe body 9 is connected to the water turbine of the reel-type sprinkler. Before operation, the pipe opening 41 on the horizontal connecting pipe 33 is opened, and the rotating pipe 17 in the outer pipe 18 is driven to rotate synchronously by rotating the outer pipe 18 wrapped by the rotating member 15, and the spiral protrusion 19 on the inner wall of the rotating pipe 17 is engaged with the spiral pattern 27 on the outer wall of the support rod shaft 23. When the rotating member 15 rotates, the rotating member 15 moves along the support rod shaft 23 and compresses the spring 57. The front end ring 21 wrapped around the front end of the outer tube 18 drives the rubber ring 22 to move, so that the position of the rubber ring 22 in the front end connecting pipe 28 changes, and the volume of the space separated by the rubber ring 22 in the front end connecting pipe 28 changes. After the adjustment is completed, the pipe opening 41 on the horizontal connecting pipe 33 is closed, the pulling drive member 4 is opened, and the drive motor 11 starts to work.

[0045] When the driving motor 11 is in operation, the dragging shaft 12 is dragged. The dragging tube 13 drags the dragging cable 1 55 and the dragging cable 2 56 under the movement of the dragging shaft 12. Under the limit of the two limit discs 47, the dragging cable 1 55 drags the support rod shaft 23, and the dragging cable 2 56 drags the sliding cylinder 50. When the sliding cylinder 50 moves downward in the main pipe body 42, the compression spring 51 is squeezed. When the sliding cylinder 50 moves downward, the compression spring 51 is squeezed. The released pesticide liquid enters the main pipe body 42. When the sliding cylinder 50 moves below the insertion pipe port 44, the diluted pesticide liquid contacts the one-way valve 1 52 of the hose pipe body 9 at the suction port 45. The dragging rope 1 55 drags the support rod shaft 23. The tail end special-shaped block 24 at the tail of the support rod shaft 23 slides in the special-shaped hole 39 at the bottom of the fixed outer tube 36. The spring 2 58 is squeezed while the tail end special-shaped block 24 is running. The spiral pattern 27 on the outside of the support rod shaft 23 and the spiral protrusion of the rotating pipe 17 are pressed. When the two ends of the hose 19 are engaged, the support rod shaft 23 drives the rotating member 15 to move synchronously. As the rubber ring 22 moves backward, a negative pressure is formed in the space inside the front connecting pipe 28, and the gas in the hose body 9 is sucked through the one-way valve 3 54 at the end of the branch pipe 10, so that a negative pressure state is formed in the hose body 9. When the one-way valve 1 52 at the upper end of the hose body 9 is in a negative pressure state in the hose body 9, the diluted pesticide liquid is sucked into the hose body 9 through the insertion pipe port 44, so that the air pressure in the hose body 9 is reduced. When the equilibrium state is reached, the pesticide dilution liquid in the hose body 9 falls into the lower part of the one-way valve 53 through the one-way valve 53 under the action of gravity, flows into the water turbine, and is further stirred and diluted through the liquid in the water turbine and the water turbine blades. During the resetting process of the dragging shaft 12, the sliding cylinder 50 is reset under the resetting property of the compression spring 51, and the insertion pipe opening 44 is blocked again. The tail end special-shaped block 24 of the tail of the support rod shaft 23 pushes the adjustment matching component 5 to be completely reset under the resetting property of the spring 58.
