Description

Technical Field

[0001] The utility model relates to the technical field of sprinkler irrigation equipment, in particular to an off-axis water dispersion device and a spray gun using the water dispersion device. Background Art

[0002] Sprinkler irrigation is a commonly used agricultural irrigation method. It uses a spray gun to direct water in a specific direction to irrigate crops or other plants. Because the water sprayed from the nozzle of the spray gun is a single stream with a narrow dispersion range, it can only irrigate the soil locally. This results in a small irrigation area and uneven irrigation, which can easily lead to over-irrigation in some areas and insufficient irrigation in surrounding areas.

[0003] Patent application with publication number CN112314413A discloses a rotary spray gun for irrigation equipment, which is equipped with a long-range nozzle, a short-range nozzle and a water flow blocker. Since the water flow sprayed by the short-range nozzle is guided to one side of the rotary spray gun through the water flow blocker, the short-range nozzle can only spray water to one side of the rotary spray gun, and the water flow coverage range is narrow. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a different-axis water dispersion device and a spray gun using the water dispersion device, which are used to solve the problems of small irrigation area and uneven irrigation during current spray gun irrigation.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A heteroaxial water dispersion device comprises at least two auxiliary water spray pipes and a rotatable water dispersion wheel arranged before the water outlet of each auxiliary water spray pipe. The axes of the water dispersion wheels are staggered. The auxiliary water spray pipes are connected to a pressurized water source. The water flow sprayed by the auxiliary water spray pipes rushes towards the blades of the water dispersion wheel.

[0007] Furthermore, the bottom of the water-spreading wheel is a circular wheel disc with a hub at its center. The blades are fixedly connected to the upper surface of the wheel disc along the circumferential direction of the wheel disc, and a support seat is rotatably connected to the lower side of the hub.

[0008] Furthermore, it also includes a water chamber, and the auxiliary water spray pipe is connected to the water chamber.

[0009] Furthermore, at least one water separator is provided on the water chamber.

[0010] Furthermore, the auxiliary water spray pipes are parallel to each other, the auxiliary water spray pipes are arranged along the tangent direction of the water sprinkler, and the water sprinkler is staggered along the axial direction of the auxiliary water spray pipe.

[0011] Furthermore, each water distributor includes a first regulating valve and a water outlet pipe arranged on the water outlet of the first regulating valve, the first regulating valve is connected to the water chamber, one end of the water outlet pipe is connected to the first regulating valve, and the other end is fixedly connected to a support arm, a water diversion rod is connected to the support arm, the end of the water outlet pipe away from the first regulating valve is a water outlet, and one end of the water diversion rod is blocked outside the water outlet; the support arm is L-shaped, the support arm is fixedly connected to the outer wall of the water outlet pipe, and the water diversion rod is threadedly connected to the support arm; the end of the water diversion rod close to the water outlet is conical, and the other end of the water diversion rod is provided with an end cap, and a spring is sleeved on the water diversion rod, and the spring is arranged between the end cap and the support arm.

[0012] A spray gun using a water dispersion device also includes a rotary spray gun, wherein the auxiliary water spray pipe is connected to the main water spray pipe of the rotary spray gun, and the water dispersion wheel is rotatably connected to the main water spray pipe.

[0013] Furthermore, screws are threadedly connected to both sides of the lower part of the suspension bracket of the rotary spray gun, and a second regulating valve is provided on the steering nozzle of the rotary spray gun.

[0014] The positive effects of this utility model are:

[0015] 1. The water dispersion device is equipped with two auxiliary water spray pipes and two water dispersion wheels. The two water dispersion wheels are staggered and their rotation axes are parallel. When the water flow sprayed from the two auxiliary water spray pipes hits the water dispersion wheels, it drives the water dispersion wheels to rotate. At the same time, under the action of centrifugal force, the water flow is dispersed and falls around the water dispersion wheels, so that the water flow covers a larger range on the soil, the coverage area is larger, and the soil irrigation is more uniform.

[0016] 2. The water dispersion device is also equipped with a water distributor, which includes a water outlet pipe and a water distributor rod. The water flows out from the water outlet of the water outlet pipe and sprays vertically toward the water distributor rod. After the water hits the water distributor rod, it is dispersed, thereby expanding the area of ​​sprinkler irrigation, irrigating more soil, and making the soil irrigation more uniform.

[0017] 3. When the water dispersion device is installed on the rotary spray gun, when the rotary spray gun is performing rotary sprinkler irrigation, the water flow sprayed from the main water spray pipe of the rotary spray gun, the water flow dispersed by the water spreader and the water flow dispersed by the water distributor form three layers of nested concentric circles on the soil, thereby making the irrigation area larger and the irrigation more uniform.

[0027] Example 1

[0028] like Figures 1 to 3 As shown, an off-axis water dispersion device comprises a water chamber 5 with pressurized water flowing therethrough and two auxiliary water spray pipes 3 connected to the left side of the water chamber 5. A rotatable water dispersion wheel 2 is located to the left of the water outlet at the left end of each auxiliary water spray pipe 3. The two auxiliary water spray pipes 3 are parallel to each other and arranged side by side in a horizontal direction. The axes of the two water dispersion wheels 2 are parallel to the auxiliary water spray pipes 3 and to each other, and the water sprayed from the two auxiliary water spray pipes 3 is directed towards the blades of the water dispersion wheel 2.

[0029] The bottom of the water-spreading wheel 2 is a circular wheel disc with a hub at the center. The blades are fixedly connected to the upper surface of the wheel disc along the circumferential direction of the wheel disc. A support seat 1 is provided under the hub. A rotating shaft is fixedly provided on the support seat 1. The hub is provided through the rotating shaft and is rotatably connected to the rotating shaft.

[0030] The top of the water chamber 5 is provided with a water distributor 4 at positions corresponding to the two auxiliary water spray pipes 3 .

[0031] The two auxiliary water spray pipes 3 are respectively arranged tangentially along the corresponding water sprinklers 2. The water sprinklers 2 are staggered along the axial direction of the auxiliary water spray pipes 3. The water flows sprayed from the two auxiliary water spray pipes 3 are respectively sprayed on the inner blades of the water sprinkler 2.

[0032] The water flows sprayed from the two auxiliary water spray pipes 3 respectively impact the corresponding water spreaders 2. The water flows sprayed on the blades of the water spreaders 2 drive the two water spreaders 2 to rotate in opposite directions while splashing. Part of the water flow is thrown out along the tangential direction of the water spreaders 2 under the action of centrifugal force, so that the water flow is dispersed over a larger area on the soil below the water spreaders 2, thereby irrigating a larger area of ​​the soil and irrigating more evenly.

[0033] Example 2

[0034] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that:

[0035] The water distributor 4 includes a first regulating valve 407 and an outlet pipe 405 disposed at the outlet of the first regulating valve 407. The water in the first regulating valve 407 flows vertically from bottom to top, with the water inlet pipe 408 of the first regulating valve 407 located below and the water outlet located above. The outlet pipe 405 is vertical at its lower portion and tilted from the upper left to the lower right at its upper portion. The lower end of the outlet pipe 405 is fixedly connected to the first regulating valve 407. A support arm 402 is fixedly connected to the top of the outer wall of the upper left end of the outlet pipe 405. A water diversion rod 401 is connected to the support arm 402. A water spout 409 is located at the upper left end of the outlet pipe 405, with one end of the water diversion rod 401 blocking the water spout 409. The inlet pipe 408 is threaded and screwed onto the top of the water chamber 5.

[0036] The support arm 402 is L-shaped and arranged from the upper left to the lower right. The lower right end of the support arm 402 is fixedly connected to the outer wall of the water outlet pipe 405. The upper left part of the support arm 402 extends out of the water outlet pipe 405. The upper left part of the support arm 402 is parallel to the axis of the upper left part of the water outlet pipe 405. The water diversion rod 401 is arranged from the lower left to the upper right. The middle part of the water diversion rod 401 is vertically threaded through the support arm 402, so that the axis of the water diversion rod 401 is perpendicular to the axis of the upper left part of the water outlet pipe 405.

[0037] The lower left end of the water-dividing rod 401 is conical, and the upper right end of the rod 401 is fixed with a cylindrical end cap 404, whose outer circumference is knurled. A spring 403 is sleeved on the water-dividing rod 401, disposed between the end cap 404 and the support arm 402, with its ends resting against the end cap 404 and the support arm 402, respectively.

[0038] The angle α between the upper left axis of the outlet pipe 405 and the axis of the inlet pipe 408 is 40°, allowing the water sprayed from the outlet pipe 405 to travel farther. Water from the outlet pipe 405, ejected from the water spout 409, is directed vertically toward the water diversion rod 401. After striking the water diversion rod 401, the water is dispersed, thereby expanding the irrigation area and irrigating more soil, resulting in more uniform irrigation.

[0039] Under the action of spring 403, the external thread in the middle of water diverter rod 401 and the corresponding internal thread on support arm 402 abut against each other and self-lock, thus preventing the water diverter rod 401 from vibrating during the spraying process due to the impact of the water flow from the water outlet pipe 5 and the water diverter rod 401. This could cause the position of the water diverter rod 401 to shift along its axis, affecting the water diverter rod's water diversion effect or causing the water diversion effect to be unstable. The position of the water diverter rod 401 can be adjusted by turning the end cap 404, thereby adjusting the water dispersion effect.

[0040] The first regulating valve 407 is a straight-through ball valve. In actual production, the first regulating valve 407 and the water outlet pipe 405 can be made into one piece, thereby reducing production costs and making mass production more convenient.

[0041] The left end face of the outlet pipe 405 is vertical, that is, the left end face of the outlet pipe 405 is parallel to the axis of the water inlet pipe 408 of the first regulating valve 407. Therefore, the space on the left side of the outlet pipe 405 is larger, which can prevent the outlet pipe 405 from blocking the dispersed water flow and affecting the sprinkler irrigation effect.

[0042] By turning the knob 406 of the first regulating valve 407, the flow rate and pressure of the water sprayed from the outlet pipe 405 can be adjusted, thereby adjusting the range of the sprinkler irrigation so that the soil near and far can be irrigated and the sprinkler irrigation can be increased evenly.

[0043] like Figure 6 As shown, the first regulating valve 407 is a right-angle stop valve, meaning its water inlet pipe 408 and outlet are oriented at a 90-degree angle. The outlet pipe 405 is fixedly connected to the outlet on the left side of the first regulating valve 407. Because the knob 406 of the first regulating valve 407 is located at the top, there is more room for the hand to turn the knob, making operation more convenient.

[0044] The outlet pipe 405 is connected to the first regulating valve 407 by threads. During production, the outlet pipe 405, the support arm 402, the water diversion rod 401, the end cap 404 and the spring 403 are assembled into a whole, and the first regulating valve 407 of the corresponding type is matched as needed.

[0045] Example 3

[0046] Combine Figure 3As shown, a spray gun using a water dispersion device. The aforementioned water dispersion device also includes a rotary spray gun. The water chamber 5 is connected to the main water spray pipe 6 of the rotary spray gun, and the water dispersion wheel 2 is rotatably connected to the main water spray pipe 6. The main water spray pipe 6 is connected to a pressurized water source. The bottom of the support base 1 is fixedly connected to an annular connector 7. The connector 7 is sleeved on the main water spray pipe 7 and fixedly connected to the middle portion of the main water spray pipe 6 by screws.

[0047] When the rotary spray gun rotates, the two water-spreading wheels 2 and the two water distributors 4 are driven to move and rotate.

[0048] like Figure 4 As shown, the center of each concentric circle is the rotation center of the rotary spray gun. The three concentric rings, from outside to inside, are designated A, B, and C. A represents the ring formed on the soil by the water flow from the main spray pipe 7, B represents the ring formed on the soil by the water distributor 1, and C represents the ring formed on the soil by the water distributor 4. Therefore, when the rotary spray gun rotates, the irrigation area is larger and the water coverage is more uniform. Because the two water distributors 2 and the two water distributors 4 are staggered axially along the main spray pipe 7, the water flow dispersion effect is enhanced.

[0049] Example 4

[0050] like Figure 3 and Figure 7 As shown, water jetted from the steering nozzle 9 at the bottom of the rotary spray gun hits the steering wheel 10 of the rotary spray gun. The steering wheel 10 rotates under the impact of the water flow, driving the rotary spray gun through the transmission box 11. The steering nozzle 9 swings back and forth within the rotary spray gun's suspension bracket 8, reciprocatingly impacting the blades on the front and rear sides of the steering wheel 18, causing the steering wheel 18 to repeatedly rotate forward and reverse, thereby driving the rotary spray gun to rotate back and forth.

[0051] The difference between this embodiment and embodiment 3 is that:

[0052] The lower side of the suspension bracket 8 of the rotary spray gun is threadedly connected with screws 13 on both sides. The screws are butterfly screws. By adjusting the position of the screws 13, the swing range and swing period of the steering nozzle 9 can be limited, thereby controlling the swing period of the rotary spray gun.

[0053] The steering nozzle 9 of the rotary spray gun is provided with a second regulating valve 12. By adjusting the opening of the second regulating valve 12, the flow rate and pressure of the water sprayed from the steering nozzle 9 can be adjusted, thereby adjusting the swing speed of the steering nozzle 9 and further adjusting the rotation speed of the rotary spray gun.
