Description

Technical Field

[0001] The utility model relates to the technical field of sprinkler irrigation equipment, in particular to a high-efficiency irrigation spray gun with uniform spraying. Background Art

[0002] A commonly used irrigation device for sprinkler irrigation is a rotatable spray gun, which is provided with a lower base, an upper base, a spray gun body and a nozzle connected in sequence, a driving device is provided on the spray gun body, a steering nozzle is provided on the upper base, and a steering wheel is provided on the driving device.

[0003] The lower base is connected to the pressure water pipeline, and the water passes through the lower base, the upper base and the spray gun body in turn and then sprays out from the nozzle to irrigate the surrounding soil. Part of the water flowing through the upper base is led out by the steering nozzle and sprayed to the steering wheel, driving the steering wheel to rotate. The steering wheel drives the transmission rod to rotate through the driving device, and then drives the upper base to rotate on the lower base, realizing the rotation of the spray gun, so that the sprayed water flow is sprayed in a ring around the spray gun.

[0004] When the spray gun is irrigating, if the flow rate of the nozzle is large and the flow rate of the steering spray pipe is small, the torque applied to the steering wheel is too small, causing the spray gun to rotate too slowly. The water sprayed from the nozzle will not be able to infiltrate into the ground in time due to excessive flow and will accumulate, affecting the irrigation effect.

[0005] If the steering water spray pipe of this type of spray gun is blocked, the water flow will be poor, or if the water pressure in the on-site pipeline is low, the water flow and impact force sprayed on the steering wheel will be reduced, causing the steering wheel speed to decrease or even fail to rotate, which will cause the spray gun speed to decrease or even fail to rotate.

[0006] In addition, once this type of spray gun starts working, the flow rate of the steering water spray pipe will remain constant, so the speed of the steering wheel is also constant and cannot be adjusted, and the rotation speed of the spray gun cannot be adjusted by changing the speed of the steering wheel. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide an efficient irrigation spray gun with uniform spraying, which is used to solve the problem that the current spray gun is prone to the problem that the flow rate of the turning water spray pipe is small, the spray gun rotates too slowly, resulting in the water sprayed from the nozzle having too large a flow rate and failing to infiltrate and accumulate on the ground in time, thus affecting the irrigation effect.

[0008] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0009] A high-efficiency irrigation spray gun with uniform spraying, the spray gun has two steering discs, each of which includes a circular disc body, blades fixedly arranged on one side of the disc body, and a hub vertically fixedly arranged at the center of the disc body, the hubs of the two steering discs are coaxial and both are connected to the worm of a driving device of the spray gun, the blades are a plurality of pieces evenly distributed along the circumferential direction of the disc body, the blades are perpendicular to the corresponding steering discs, the spray gun has two steering water spray pipes, the two steering water spray pipes are connected to the upper base of the spray gun, and the water outlets of the two steering water spray pipes are respectively oriented toward the corresponding steering discs.

[0010] Furthermore, one side of the disc body provided with the blades is the front side, and the other side is the back side, and the front sides of the disc bodies of the two steering discs face in opposite directions.

[0011] Furthermore, the wheels of the two steering wheels overlap as one, and the hubs of the two steering wheels overlap as one.

[0012] Furthermore, the blades on the two steering wheels are arranged in an interlaced manner.

[0013] Furthermore, each blade is arranged along the radial direction of the disk body, and the blades are arranged at a position close to the edge of the disk body, and there is a gap between the inner side of the blade and the hub.

[0014] Furthermore, at least one of the two diverting water spray pipes is provided with a valve.

[0015] Furthermore, a water retaining sleeve coaxial with the hub of the driving device is provided outside the hub close to the driving device, the water retaining sleeve is fixedly connected to the disc body, and the water retaining sleeve is sleeved outside the worm.

[0016] Furthermore, it also includes a rigid stabilizing sleeve, and two steering water spray pipes are both penetrated and fixedly connected with the stabilizing sleeve.

[0017] Furthermore, the number of blades on the lower steering wheel is greater than the number of blades on the upper steering wheel.

[0018] The positive effects of the utility model are:

[0019] 1. The utility model is provided with two steering water spray pipes and two steering wheels, thereby increasing the impact force of the water flow, making the steering wheel rotate faster and receiving greater force, so that the sprayed water flow quickly sweeps the surrounding soil, avoiding the local accumulation of the sprayed water and affecting the irrigation effect. After the two steering water spray pipes and two steering wheels are provided, even if the water pressure is low, sufficient impact force can be generated to ensure the normal rotation of the steering wheel. The provision of two steering water spray pipes also increases the reliability of the utility model, and even if one steering water spray pipe is blocked, the normal operation of the utility model can be guaranteed. When the water sprayed from the steering water spray pipe hits the steering wheel, the water is dispersed, thereby irrigating the position close to the center of the spray gun, so that the soil far away and near the spray gun can be irrigated, thereby improving the irrigation coverage area and efficiency.

[0020] 2. A valve is installed on the steering water spray pipe. By adjusting the opening of the valve, the size of the water flow that impacts the steering wheel can be adjusted, thereby adjusting the rotation speed of the steering wheel. The rotation speed of the spray gun can be adjusted according to the actual water pressure and soil conditions on site to achieve better sprinkler irrigation effects.

[0021] 3. The utility model is provided with a water retaining sleeve under the disc body. When the water retaining sleeve rotates, the splashing water is thrown out under the action of centrifugal force, which can prevent the water splashed onto the worm of the spray gun from flowing downward with the worm under the action of gravity, and then entering the housing through the gap between the worm and the housing, causing damage to the bearing.

[0022] 4. The two steering wheels can be combined into one, that is, the two steering wheels use the same disc body and the same hub, the blades are arranged on both sides of the disc body, and the blades are integrally formed with the disc body, the hub and the water retaining sleeve, thereby reducing material consumption and reducing production costs.

[0023] 5. Stabilizing sleeves are provided on the two steering water spray pipes to increase the rigidity of the two steering nozzles, thereby ensuring that the water flow sprayed from the two steering nozzles exerts the same impulse on the steering wheel, making the torque of the steering wheel acting on the worm of the driving device more stable, thereby increasing the stability of the utility model during operation.

[0024] 6. The number of blades of the upper steering wheel is less than that of the lower steering wheel. Therefore, the water flow ejected from the lower water spray pipe collides with more blades, so it is more dispersed, and the force of the water flow is reduced after being hit by more blades, so that the water flow dispersed by the lower steering wheel falls on the ground closer to the rotation center of the spray gun than the water flow dispersed by the upper steering wheel. Therefore, the water flow ejected by the utility model is distributed in three layers, making the soil spray irrigation of the utility model more uniform. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Example 1

[0034] like Figure 1 As shown, the current spray gun includes a lower base 1, an upper base 2 that can rotate on the top of the lower base 1, a spray gun body 3 fixedly arranged on the upper base 2, and a spray head 4 fixedly arranged at the outer end of the spray gun body 3. A driving device 7 is fixedly arranged under the spray gun body 3, and a steering wheel 8 is arranged on the driving device 7. A steering water spray pipe 5 is connected to the upper base 2, and the water outlet of the steering water spray pipe 5 faces the steering wheel 8.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a high-efficiency irrigation spray gun with uniform spraying has two steering discs 8 arranged in an upper and lower position, each steering disc 8 includes a circular disc body 10, blades 9 fixedly arranged on one side of the disc body 10, and a hub 11 vertically penetrating and fixedly arranged in the center of the disc body 10. The hubs 11 of the two steering discs 8 are coaxial, and the blades 9 on each steering disc 8 are ten blades evenly distributed along the circumferential direction of the corresponding disc body 10, and each blade 9 is perpendicular to the corresponding steering disc 8. There are two steering water spray pipes 5 of the spray gun, and the two steering water spray pipes 5 are connected to the upper base 2, and the water outlet of the upper steering water spray pipe 5 faces the upper steering disc 8, and the water outlet of the lower steering water spray pipe 5 faces the lower steering disc 8. The hubs 11 of the two steering discs 8 are connected to the upper part of the worm of the driving device 7 through a key.

[0036] One side of the disc body 10 provided with the blade 9 is the front side, and the other side is the back side, and the disc body 10 of the upper steering wheel 8 faces upwards and the back side faces downwards. The disc body 10 of the lower steering wheel 8 faces downwards and the back side faces upwards.

[0037] The water in the upper base 2 flows into the steering water spray pipe 5 and is sprayed from the right end of the steering water spray pipe 5 to the corresponding steering wheel 8. The steering wheel 8 rotates after being impacted by the water flow, driving the worm in the driving device 7 to rotate, and then driving the transmission rod 13 to rotate through the worm wheel and gear in the driving device 7 in turn. The left end of the transmission rod 1 is provided with a worm, which is meshed with the worm wheel fixed on the lower base. The worm can drive the upper base 2 to rotate on the lower base 1, thereby driving the spray gun body 3 to rotate.

[0038] The use of two steering water spray pipes 5 and two steering wheels 8 increases the impact force of the water flow, making the steering wheel 8 rotate faster and receiving greater force, so that the sprayed water flow quickly sweeps the surrounding soil, avoiding local accumulation of the sprayed water and affecting the irrigation effect.

[0039] After two steering water spray pipes 5 and two steering wheels 8 are provided, even if the water pressure is low, sufficient impact force can be generated to ensure the normal rotation of the steering wheel 8. The two steering water spray pipes 5 are provided to increase reliability, and the normal operation of the utility model can be ensured even if one steering water spray pipe 5 is blocked.

[0040] When the water sprayed from the deflection spray pipe 5 hits the blades 9, the water is dispersed, thereby irrigating the position near the center of the spray gun, so that the soil far away from the spray gun and near the spray gun can be irrigated. When the water sprayed from the upper deflection spray pipe 5 hits the blades 9, part of the water will flow to the upper surface of the upper disc 10 under the action of gravity, and then be thrown out under the action of centrifugal force as the disc 10 rotates, thereby increasing the irrigation area of ​​the nearby soil.

[0041] Each blade 9 is arranged along the radial direction of the disc body 10, and the blades 9 are arranged near the edge of the disc body 10, and there is a gap between the inner side of the blade 9 and the hub 11. The gap allows the splashing water to repeatedly splash between the blades 9, so that it is dispersed more evenly.

[0042] A water retaining sleeve 12 coaxial with the wheel hub 11 near the lower steering wheel 8 is provided outside the wheel hub 11 . The water retaining sleeve 12 is fixedly connected to the disc body 10 , and the water retaining sleeve 12 is sleeved outside the worm of the driving device 7 .

[0043] Since the worm of the drive device 7 extends out of the housing of the drive device 7, there is a bearing between the housing and the worm. After the water retaining sleeve 12 is set, it can prevent the water splashed on the worm from flowing downward with the worm under gravity, entering the housing through the gap between the worm and the housing, causing bearing damage.

[0044] In actual production, the disc body 10, wheel hub 11 and blades 9 of the upper steering wheel 8 are integrally formed, and the disc body 10, wheel hub 11, blades 9 and water retaining sleeve 12 of the lower steering wheel 8 are integrally formed, so as to facilitate mass production.

[0045] Example 2

[0046] like Figure 1 As shown, the difference between this embodiment and embodiment 1 is that:

[0047] Each steering water spray pipe 5 is provided with a valve 6. By adjusting the opening of the valve 6, the size of the water flow impacting the steering wheel 8 can be adjusted, thereby adjusting the rotation speed of the steering wheel 8, and then the rotation speed of the spray gun can be adjusted according to the actual water pressure and actual soil conditions on site, so as to achieve a better sprinkler irrigation effect.

[0048] The number of blades 9 on the two steering wheels 8 is equal and there are ten blades on each of them. The blades 9 on the two steering wheels 8 are arranged in an interlaced manner. When the water flow from the two steering water pipes 5 impacts the two steering wheels 8, the torque transmitted to the worm of the driving device 7 by the two steering wheels 8 can be more uniform without pulsation.

[0049] Example 3

[0050] like Figure 3 As shown, the difference between this embodiment and embodiment 1 is that:

[0051] The disc bodies 10 of the two steering wheels 8 overlap as one body, and the wheel hubs 11 of the two steering wheels 8 overlap as one body. Specifically, in actual production, the two steering wheels 8 use the same disc body 10 and the same wheel hub 11, and the blades on both sides of the disc body 10 are integrally formed with the disc body 10, the wheel hub 11 and the water retaining sleeve 12, thereby reducing the amount of materials used and reducing the production cost.

[0052] Example 4

[0053] like Figure 6 As shown, the difference between this embodiment and embodiment 3 is that:

[0054] The utility model is also provided with a rigid stabilizing sleeve 14 , which is rectangular, with two ends of the stabilizing sleeve 14 close to the upper base 2 and the steering wheel 8 respectively, and two steering water spraying pipes 5 are both penetrated and fixedly connected with the stabilizing sleeve 14 .

[0055] When the utility model is working, the steering water spray pipe 5 is slender and can easily swing under the reaction of the water flow impact, and the spray gun itself is also rotating, so that the water flow sprayed from the steering spray pipe 5 impacts different positions of the steering wheel 8, which can easily cause the two steering water spray pipes 5 to impact different positions of the steering wheel 8, thereby making the torque applied by the steering wheel 8 to the worm of the driving device 7 unstable, and in severe cases, causing the steering wheel 8 to fail to rotate normally.

[0056] After adding the stabilizing sleeve 14, the rigidity of the two steering nozzles 5 is increased, thereby ensuring that the water flow sprayed from the two steering nozzles 5 exerts the same impulse on the steering wheel 8, making the torque of the steering wheel 8 acting on the worm of the driving device 7 more stable, thereby increasing the stability of the utility model during operation.

[0057] Example 5

[0058] The difference between this embodiment and embodiment 1 is that:

[0059] The number of blades 9 of the upper steering wheel 8 is five, and the number of blades 9 of the lower steering wheel 8 is ten.

[0060] Since the number of blades 9 of the lower steering wheel 8 is ten, which is greater than the number of blades of the upper steering wheel 8, the water flow ejected from the lower water spray pipe 10 collides with more blades 9, thereby being more dispersed, and the force of the water flow is reduced after being hit by more blades 9, so that the water flow dispersed by the lower steering wheel 8 falls on the ground closer to the rotation center of the spray gun than the water flow dispersed by the upper steering wheel 8, so that the water flow ejected by the utility model is distributed in three layers, which are the water flow ejected by the nozzle 4, the water flow dispersed by the upper steering wheel 8, and the water flow dispersed by the lower steering wheel 8 from far to near, so that the soil spraying of the utility model is more uniform.

[0061] The above embodiment is improved on the basis of the publication number CN213967208U, which is named a variable speed automatic rotating spray gun. In practice, the above scheme can be adopted for spray guns using steering water spray pipes and steering wheels. The above embodiment description is relatively detailed and specific, expressing the preferred embodiment of the utility model, which is only used to illustrate the technical ideas and features of the utility model. Its purpose is to enable technicians in this field to understand the content of the utility model and implement it accordingly, but it is not limited to the utility model. The patent scope of the utility model cannot be limited only by this embodiment, that is, all equivalent changes or modifications made to the spirit disclosed by the utility model, for researchers or technicians in this field, within the structure of the utility model, the local improvement of the system and the changes and transformations between subsystems are still within the patent scope of the utility model. At present, the technical solution of this application has been piloted, that is, a small-scale experiment of the product before large-scale mass production; after the pilot was completed, a user use survey was carried out in a small range, and the survey results showed that the user satisfaction was high; now it is preparing for the formal production of the product for industrialization, including intellectual property risk warning survey.
