Description

Technical Field

[0001] This utility model relates to the field of irrigation-related technology, specifically a ram's horn nozzle that reduces rotational friction. Background Technology

[0002] Currently, there are two main types of rotary sprinklers on the market. The first type is the rocker arm rotary sprinkler (referred to as rocker arm sprinkler) designed based on mechanical principles, and the second type is the jet rotary sprinkler (referred to as jet sprinkler) designed based on fluid dynamics principles. When using these two types of sprinklers, people have found that they have disadvantages such as uneven spraying, unstable spray frame, easy to tip over, uneven and unstable rotation speed, inability to achieve large-scale and large-area irrigation, poor sealing effect, and short service life.

[0003] A Chinese patent (CN205761890U) relates to a differential force rotary nozzle, which includes a V-shaped rotating arm, a nozzle, a dust cap, a sealing cap, a washer, a limiting nut, a bearing housing, a bearing bush, an oil seal, a first sealing ring, a second sealing ring, and a third sealing ring. The limiting nut is threaded onto the lower arm of the V-shaped rotating arm. Above the limiting nut, the washer, the sealing cap, and the dust cap are sequentially fitted from bottom to top on the arm of the V-shaped rotating arm. The sealing cap has a second sealing ring on its inner wall and a third sealing ring on its outer wall. The dust cap has a first sealing ring on its inner wall. The bearing housing is fitted over the sealing cap, the washer, and the limiting nut, with its upper end threaded to the sealing cap. Inside the bearing housing, between the limiting nut and the bearing housing, a bearing bush is provided. Inside the bearing housing, between the arm of the V-shaped rotating arm and the bearing housing, an oil seal is provided. The nozzle has a simple and reasonable structure, does not require frequent lubrication oil changes, has a good sealing effect, can achieve uniform low-speed rotation, uniform water spray, save water resources, and is easy to install and disassemble.

[0004] However, it only has one bearing to achieve rotation, which results in a small contact area between the arm and the bearing housing, which may lead to rotational friction, increased torque, decreased speed, and poor spray uniformity. Utility Model Content

[0005] The purpose of this invention is to provide a ram's horn nozzle that reduces rotational friction, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A horn-shaped nozzle for reducing rotational friction includes a rotating base and two rotating arms fixed to and communicating with the rotating base. The nozzle is detachably mounted on each rotating arm. The nozzle also includes:

[0008] A fixing member that is sleeved on the rotating seat and can move relative to the rotating seat;

[0009] A detachable limiting ring is installed on the rotating seat, and the limiting ring is provided with a first bearing and a second bearing at both ends along the axial direction of the rotating seat;

[0010] A connecting sleeve with an annular protrusion is formed. After the connecting sleeve is fitted onto the rotating seat and fixed to the fixing member, the fixing member and the annular protrusion are respectively pressed against the first bearing and the second bearing.

[0011] As described above, the horn-shaped nozzle with reduced rotational friction has the rotating base welded to the rotating arm as a single unit.

[0012] As described above, the ram's horn nozzle for reducing rotational friction includes a rotating arm comprising a V-shaped head welded integrally with the rotating seat, a connecting arm threadedly connected to the end of the V-shaped head away from the rotating seat, and the nozzle being mounted on the end of the connecting arm away from the V-shaped head.

[0013] As described above, the horn-shaped nozzle with reduced rotational friction has a first external thread at one end of the fixing member facing the connecting sleeve. The connecting sleeve is fitted onto the first external thread and is threadedly connected to the first external thread through a first internal thread formed on the inner side of the connecting sleeve.

[0014] As described above, the horn-shaped nozzle with reduced rotational friction has a first sealing ring embedded in the inner side of the end of the fixing member facing the first bearing. When the fixing member is fixed to the connector, the first sealing ring is pressed against the first bearing.

[0015] As described above, the horn-shaped nozzle for reducing rotational friction has a second sealing ring on the side of the annular protrusion away from the second bearing, and the second sealing ring is located in the gap formed between the rotating seat and the connecting sleeve.

[0016] The horn-shaped nozzle for reducing rotational friction as described above also includes a water distribution assembly, which includes a water distribution needle whose length direction is perpendicular to the water outlet direction of the nozzle, and the water distribution needle is connected to a connecting rod.

[0017] As described above, the ram's horn nozzle with reduced rotational friction has the following configuration: the end of the connecting rod away from the water distribution needle is fixedly connected to an annular connector fixed to the nozzle.

A threaded rod is also formed on the L-shaped rod, which passes through a mounting through hole formed on the nozzle and is fixed by a fastener.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The setting of the limiting ring, together with the first and second bearings at both ends, can effectively improve the smoothness of the rotation of the rotating seat. At the same time, the setting of the first and second bearings can also effectively reduce the friction and wear generated during the rotation of the rotating seat, and extend the service life of the equipment. The fixing part and the annular protrusion are pressed tightly on the first and second bearings respectively, making the rotating seat more stable during rotation and reducing the possibility of shaking and deviation.

Detailed Implementation

[0034] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0035] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0036] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0037] Please see Figures 1-6 As a type of horn-shaped nozzle for reducing rotational friction according to this utility model, it includes a rotating base 2 and two rotating arms 1 fixed to and connected to the rotating base 2. A nozzle 5 is detachably mounted on each rotating arm 1. It also includes:

[0038] A fixing member 3 that is sleeved on the rotating seat 2 and can move relative to the rotating seat 2;

[0039] A limiting ring 11 is detachably installed on the rotating seat 2. The limiting ring 11 is provided with a first bearing 10 and a second bearing 12 at both ends along the axial direction of the rotating seat 2.

[0040] A connecting sleeve 4 with an annular protrusion 402 is fitted onto the rotating seat 2 and fixed to the fixing member 3. The fixing member 3 and the annular protrusion 402 are respectively pressed onto the first bearing 10 and the second bearing 12.

[0041] The inner side of the end of the connecting sleeve 4 away from the fixing part 3 has a second internal thread 403 for connecting the water inlet pipe. When the water pump pressurizes the water and delivers it to the rotating seat 2 through the water inlet pipe, the pressurized water is sent to the nozzle 5 through the rotating arm 1. The water flows out through the nozzle 5. At the same time, the reflective hole provided on the nozzle 5 causes the nozzle 5 to drive the rotating arm 1 and the rotating seat 2 to rotate as a whole, thereby realizing the function of rotating water spraying.

[0042] In this embodiment, the limiting ring 11, in conjunction with the first bearing 10 and the second bearing 12 at both ends, can effectively improve the smoothness of rotation of the rotating seat 2. At the same time, the setting of the first bearing 10 and the second bearing 12 can also effectively reduce the friction and wear generated during the rotation of the rotating seat 2, and extend the service life of the equipment. The fixing part 3 and the annular protrusion 402 are respectively pressed on the first bearing 10 and the second bearing 12, making the rotating seat 2 more stable when rotating and reducing the possibility of shaking and displacement.

[0043] Preferably, the rotating seat 2 has a second external thread 301 formed thereon, and the limiting ring 11 can be threadedly connected to the second external thread 301 after being sleeved on the rotating seat 2, thereby realizing the detachable design of the limiting ring 11.

[0044] As an example, one implementation method is described in [reference needed]. Figure 1 and Figure 2 The rotating seat 2 is welded to the rotating arm 1 as a whole.

[0045] For an exemplary, alternative implementation, please refer to [link to documentation]. Figure 7 and Figure 8 The rotating arm 1 includes a V-shaped head 101 welded to the rotating seat 2. A connecting arm 102 is threadedly connected to the end of the V-shaped head 101 away from the rotating seat 2. The nozzle 5 is installed on the end of the connecting arm 102 away from the V-shaped head 101.

[0046] With the above settings, different lengths of connecting arms 102 can be selected to extend or shorten the overall length of rotating arm 1 as needed, thereby flexibly adjusting the spray range and position of nozzle 5 to meet the usage requirements of different scenarios.

[0047] Further, please refer to Figures 3-6The fixing member 3 has a first external thread 201 at one end facing the connecting sleeve 4. The connecting sleeve 4 is sleeved on the first external thread 201 and is threadedly connected to the first external thread 201 through the first internal thread 401 formed on the inner side of the connecting sleeve 4, thereby realizing the detachable connection between the fixing member 3 and the connecting head 4, which is convenient for disassembly and assembly.

[0048] It should be noted that the fastener 3 has a hexagonal or octagonal screwing part, which facilitates the screwing operation of the fastener 3 using tools.

[0049] Preferably, a first sealing ring 9 is embedded in the inner side of the end of the fixing member 3 facing the first bearing 10. When the fixing member 3 is fixed to the connector 4, the first sealing ring 9 is pressed against the first bearing 10, thereby achieving a sealed connection.

[0050] A second sealing ring 13 is provided on the side of the annular protrusion 402 away from the second bearing 12. The second sealing ring 13 is located in the gap formed between the rotating seat 2 and the connecting sleeve 4. During installation, after the water inlet pipe is threadedly connected to the second internal thread 403 on the connector 4, the end of the water inlet pipe abuts against the second sealing ring 13. At the same time, the water inlet pipe is also sleeved on the outside of the end of the rotating seat 2, thereby achieving a sealed connection between the water inlet pipe, the connecting sleeve 4, and the rotating seat 2.

[0051] The horn-shaped sprinkler head with reduced rotational friction also includes a water-dividing component, which includes a water-dividing needle 8. The length direction of the water-dividing needle 8 is perpendicular to the water outlet direction of the sprinkler head 5. The water-dividing needle 8 is connected to a connecting rod 7. When the water flow is sprayed out from the sprinkler head 5, it will hit the water-dividing needle 8, which will disperse the water flow into multiple fine streams, thereby expanding the coverage area of ​​the water flow and improving the efficiency of cleaning or irrigation.

[0052] Please see Figure 7 and Figure 8 In one embodiment, the end of the connecting rod 7 away from the water-dividing needle 8 is fixedly connected to an annular connector 501 fixed on the nozzle 5.

[0053] Please see Figure 1 and Figure 2 In another embodiment, the end of the connecting rod 7 away from the water-dividing needle 8 is fixed to the clamp 6 installed on the rotating arm 1.

[0054] It should also be noted that the water-dividing needle 8 includes, but is not limited to, columnar and V-shaped shapes.

[0055] Please see Figures 9-11As another embodiment of the present invention, the horn-shaped nozzle for reducing rotational friction further includes a water-dividing assembly. The water-dividing assembly includes an L-shaped rod 14, on which a conical water-dividing needle 15 is fixed, facing the water outlet direction of the nozzle 5. A threaded rod 1401 is also formed on the L-shaped rod 14. The threaded rod 1401 passes through the mounting through hole 502 formed on the nozzle 5 and is fixed by a fastener.

[0056] The aforementioned fasteners include a second nut 18 and a first nut 16 located on the inner and outer sides of the nozzle 5. Both the first nut 16 and the second nut 18 are threadedly connected to the threaded rod 1401. When the threaded rod 1401 is fixed, the first nut 16 and the second nut 18 abut against the inner and outer walls of the nozzle 5, respectively.

[0057] Preferably, in order to ensure to a certain extent that the threaded rod 1401 does not rotate when the first nut 16 is rotated, an inner groove 1801 is formed on the second nut 18. A spring 17 sleeved on the threaded rod 1401 is provided in the inner groove 1801. When the first nut 16 gradually approaches the nozzle 5, the spring 17 is continuously compressed, and the force between the spring 17 and the second nut 18 gradually increases, thereby limiting the rotation of the second nut 18 to a certain extent.

[0058] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0059] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
