Description

Technical Field

[0001] This invention belongs to the field of sprinkler irrigation technology, specifically referring to a self-propelled reel sprinkler irrigation machine. Background Technology

[0002] The self-propelled reel sprinkler is a high-efficiency water-saving irrigation device, consisting of a reel main unit and a self-propelled sprinkler carriage. Its core working principle is to drive the water turbine to rotate through pressurized water, which in turn causes the reel to rotate via a speed reduction device. This winds and pulls the PE pipe connected to the sprinkler carriage, enabling the sprinkler carriage to move and spray automatically during operation.

[0003] During the operation of a self-propelled reel sprinkler, the PE pipe needs to be dragged on the ground for spraying and movement. Since the road surface is often not smooth and it is in direct contact with soil, stones and other debris for a long time, the working conditions of the PE pipe with water are very harsh, which can easily cause wear on the pipe wall. In particular, when soil and gravel adhere to the pipe wall, as the pipe is rolled up, the surface of the pipe wall is compressed by gravel and other impurities, which can damage the pipe and affect its service life. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide a self-propelled reel sprinkler to at least partially solve the problems mentioned in the background art.

[0005] The technical solution adopted by this invention is as follows: A self-propelled reel-type sprinkler irrigation machine is proposed, comprising: A reel is rotatably mounted on the body of the sprinkler irrigation machine, and a PE water pipe is wound on the reel; A self-propelled trolley is located on the side of the sprinkler machine body, and a spray gun is installed on the self-propelled trolley, which is connected to the PE water pipe. The accompanying film-laying box is fixedly installed at the lower end of the sprinkler machine body and located between the reel and the self-propelled trolley; The accompanying film-laying box includes a box body fixed to the sprinkler machine body and a protective film belt. One end of the protective film belt is fixed to the self-propelled trolley and located directly below the spray gun, so that the protective film belt supports the PE water pipe between the self-propelled trolley and the reel, preventing the PE water pipe from contacting the ground. The other end of the protective film belt is wound into the box body by a film belt reel, and the protective film belt is configured to be consistent with the winding speed of the PE water pipe, so that the PE water pipe between the self-propelled trolley and the reel is always on the protective film belt during winding.

[0006] Furthermore, a film-laying window is provided on the side of the housing facing the self-propelled vehicle. An extrusion roller and a scraper are respectively provided on the upper and lower sides of the housing corresponding to the film-laying window. The extrusion roller is configured to rotate around a set axis, and the scraper is located below the extrusion roller. The protective film strip passes through the space between the extrusion roller and the scraper and passes through the film-laying window.

[0007] Furthermore, the distance between the extrusion roller and the scraper is fixed, and when the protective film belt passes through, the extrusion roller is used to roll the protective film belt, so that the protective film belt is rolled into a flat strip onto the film belt roll, and the scraper is configured to scrape off impurities on the bottom surface of the protective film belt.

[0008] Furthermore, the protective membrane strip includes a membrane strip body and two flexible water pipes. The cross-sectional structure of the membrane strip body is a closed ring. A bonding area is provided along the length direction at the middle position of the membrane strip body. The bonding area divides the cross-section of the membrane strip body into two symmetrical water pipe cavities. The two membrane strip bodies are symmetrically distributed in the two water pipe cavities. The area on the membrane strip body corresponding to the flexible water pipe is set as a limiting protrusion, and the area on the membrane strip body corresponding to the area between the two flexible water pipes is set as a limiting groove.

[0009] Furthermore, a one-way pressure relief valve is fixedly installed at one end of the flexible water pipe near the spray gun, and the one-way pressure relief valve is configured to open only in the direction of water spraying from the spray gun.

[0010] Furthermore, the flexible water pipe includes a water-filled state and a non-water-filled state. When the flexible water pipe is in the water-filled state, the one-way pressure relief valve area protrudes, the limiting groove area is concave, and the PE water pipe is restricted by the limiting protrusions on both sides in the limiting groove area. When the flexible water pipe is in the non-water-filled state, the protective membrane strip is generally flat.

[0011] Furthermore, during operation, the reel winds up the PE water pipe at a set speed, and the self-propelled trolley gradually approaches the sprinkler machine body from the initial spraying position. The winding speed of the membrane tape reel on the protective membrane tape is equal to the moving speed of the self-propelled trolley. When the protective membrane tape is wound up, the water in the flexible water pipe is pressurized and gradually discharged from the one-way pressure relief valve, causing the protective membrane tape entering the housing to change from a water-filled state to a water-free state.

[0012] Furthermore, a first water supply pipe is provided at the axis of the reel, which is configured to supply water to the PE water pipe, and a second water supply pipe is provided at the axis of the membrane tape reel, which is configured to supply water to the flexible water pipe.

[0013] Furthermore, the diameter of the flexible water pipe is set to 1 / 2 of the diameter of the PE water pipe, and the width of the limiting groove is greater than or equal to the diameter of the PE water pipe.

[0014] Furthermore, the membrane strip body includes a PE membrane strip, and the bonding area is formed on the membrane strip body along the axial direction by adhesive bonding or stitching.

[0015] Beneficial effects: This invention, by setting up a traveling film-laying box and its protective film belt, supports the PE water pipe on the protective film belt during operation, avoiding direct contact and friction between the PE water pipe and the ground, reducing pipe wall wear, and extending the service life of the PE water pipe. The protective film belt is equipped with a water-fillable flexible water pipe. After filling with water, it forms limiting protrusions and limiting grooves, which can stably accommodate and guide the PE water pipe and prevent it from shifting during winding. During winding, the water in the flexible water pipe is gradually discharged through a one-way pressure relief valve, so that the film belt returns to a flat state, which is convenient for neat winding in the box. The extrusion rollers and scrapers at the entrance of the box can roll and clean the protective film belt before winding, removing attached moisture and impurities, and ensuring winding quality.

[0018] The accompanying drawings are provided to further understand the embodiments and form part of the specification. They are used together with the embodiments for explanation and do not constitute a limitation on the embodiments. Detailed Implementation

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0020] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0021] To address the issue of wear and tear caused by the PE water pipe 21 being dragged along the ground during the operation of current self-propelled reel sprinkler irrigation machines, this invention provides a self-propelled reel sprinkler irrigation machine, comprising a sprinkler body 10, a reel 20, a self-propelled trolley 30, and a traveling film-laying box 40.

[0022] like Figure 1 As shown, the reel 20 is rotatably mounted on the sprinkler body 10, and a PE water pipe 21 is wound on the reel 20. The self-propelled trolley 30 is located on the side of the sprinkler body 10, and a spray gun 31 is mounted on the self-propelled trolley 30. The spray gun 31 is connected to the PE water pipe 21. A pipe arranger 11 is provided on the side of the sprinkler body 10 near the self-propelled trolley 30. Its function is to guide the PE water pipe 21 to be evenly arranged on the reel 20, so as to avoid overlapping, jamming or uneven arrangement during winding.

[0023] In a typical embodiment, the pipe laying device 11 usually adopts a reciprocating screw mechanism, which moves back and forth along the axis of the reel 20 as the reel 20 rotates, so that the PE water pipes 21 are neatly arranged in a spiral shape on the reel 20.

[0024] Furthermore, the accompanying film-laying box 40 is fixedly installed at the lower end of the sprinkler machine body 10 and located between the reel 20 and the self-propelled trolley 30. It is used to lay and rewind the protective film strip 43 during operation to isolate the PE water pipe 21 from the ground.

[0025] like Figure 2 and Figure 3As shown, the accompanying film-laying box 40 includes a box body 41 fixed to the sprinkler machine body 10 and a protective film belt 43. The box body 41 is equipped with a film belt reel 42, which is driven to rotate by a drive motor 46 for winding and unwinding the protective film belt 43.

[0026] One end of the protective membrane tape 43 is fixed to the self-propelled trolley 30 and positioned directly below the spray gun 31, allowing the protective membrane tape 43 to support the PE water pipe 21 between the self-propelled trolley 30 and the reel 20, preventing the PE water pipe 21 from contacting the ground. The other end of the protective membrane tape 43 passes through the membrane laying window 410 on the housing 41 and is wound onto the membrane tape drum 42. During operation, the membrane tape drum 42 rotates synchronously with the reel 20, ensuring that the winding speed of the protective membrane tape 43 is equal to the winding speed of the PE water pipe 21. This guarantees that the PE water pipe 21 between the self-propelled trolley 30 and the reel 20 remains on the protective membrane tape 43 throughout the winding process, achieving movement without contact with the ground.

[0027] Furthermore, a film-laying window 410 is provided on the side of the box 41 facing the self-propelled vehicle 30, and an extrusion roller 44 and a scraper 45 are respectively provided on the upper and lower sides of the box 41 corresponding to the film-laying window 410.

[0028] Furthermore, the extrusion roller 44 is rotatably installed inside the housing 41, with its axis parallel to the film roll 42. It is used to roll the protective film 43 entering the housing 41, squeezing out any residual moisture and air in the film 43 to make the film 43 flat. The scraper 45 is fixed inside the housing 41, located below the extrusion roller 44, with its edge in contact with the lower surface of the protective film 43. It is used to scrape off dirt, gravel, and other impurities attached to the bottom surface of the film 43, preventing impurities from being rolled into the film roll 42 with the film 43, thus affecting the winding effect and equipment cleanliness.

[0029] In some embodiments, the distance between the extrusion roller 44 and the scraper 45 is fixed, and when the protective film belt 43 passes through, the extrusion roller 44 is used to roll the protective film belt 43 so that the protective film belt 43 is rolled into a flat strip onto the film belt roll 42, and the scraper 45 is configured to scrape off impurities on the bottom surface of the protective film belt 43.

[0030] like Figure 4 , Figure 5 and Figure 6 As shown, the protective membrane strip 43 includes a membrane strip body 431 and two flexible water pipes 432. The membrane strip body 431 is made of a flexible material (such as PE membrane) and has a closed annular cross-section, exhibiting good flexibility and wear resistance. A bonding area 433 is provided along the length direction at the middle position of the membrane strip body 431. The bonding area 433 can be formed by high-frequency welding or sewing, dividing the cross-section of the membrane strip body 431 into two independent and symmetrical water pipe cavities 4310.

[0031] Furthermore, two flexible water pipes 432 are symmetrically distributed within two water pipe cavities 4310. Each flexible water pipe 432 is a water-expandable hose, and a one-way pressure relief valve 4321 is fixedly installed at its end near the spray gun 31. The one-way pressure relief valve 4321 is configured to open only in the direction of water spray from the spray gun 31, allowing water to flow from the flexible water pipe 432 to the spray gun 31, and to stop in the opposite direction. A limiting protrusion 4312 is set on the area of ​​the membrane belt 431 corresponding to the flexible water pipe 432, and a limiting groove 4311 is set on the area of ​​the membrane belt 431 between the two flexible water pipes 432.

[0032] The flexible water pipe 432 includes a water-filled state and a non-water-filled state. When the flexible water pipe 432 is in the water-filled state, the water pipe expands, causing the corresponding area of ​​the membrane strip 431 to bulge outward to form a limiting protrusion 4312. At the same time, the area between the two limiting protrusions 4312 indents inward to form a limiting groove 4311. The PE water pipe 21 is stably positioned within the limiting groove 4311 area by the limiting protrusions 4312 on both sides, thus being both supported and limited to prevent rolling and deviation. When the flexible water pipe 432 is in the non-water-filled state, the water pipe contracts, the membrane strip 431 loses support, and the protective membrane strip 43 becomes a flat strip, which is convenient for winding and storage.

[0033] During operation, the reel 20 winds up the PE water hose 21 at a set speed, while the self-propelled trolley 30 gradually approaches the sprinkler machine body 10 from the initial spraying position. The winding speed of the protective membrane belt 43 on the membrane belt drum 42 is equal to the moving speed of the self-propelled trolley 30, ensuring that the protective membrane belt 43 is always taut and supports the PE water hose 21. As the protective membrane belt 43 enters the housing 41, the squeeze roller 44 and scraper 45 squeeze and clean it. At the same time, the water in the flexible water hose 432 is pressurized under the squeezing action and gradually discharged towards the spray gun 31 through the one-way pressure relief valve 4321. This causes the protective membrane belt 43 entering the housing 41 to gradually transition from a water-filled state to a non-water-filled state, and finally, it is neatly wound up on the membrane belt drum 42 in a flat state. This cycle continues until the self-propelled trolley 30 returns to the vicinity of the sprinkler machine body 10, completing one spraying operation.

[0034] Furthermore, the protective membrane 43 is pulled out from the box 41 as the self-propelled vehicle 30 moves and remains below the PE water pipe 21. At this time, the flexible water pipe 432 is not filled with water. When the self-propelled vehicle 30 moves to the initial position, water is filled into the flexible water pipe 432 to effectively limit the PE water pipe 21, and then the sprinkler irrigation work is carried out.

[0035] like Figure 1As shown, a first water supply pipe 01 is provided at the axis of the reel 20. The first water supply pipe 01 is connected to an external water source through a rotary joint and is configured to supply water to the PE water pipe 21. A second water supply pipe 02 is provided at the axis of the membrane tape reel 42. The second water supply pipe 02 is also connected to an external water source through a rotary joint and is configured to supply water to the flexible water pipe 432. The two supply water independently and do not interfere with each other, which makes it easy to adjust the water supply pressure and flow rate separately according to the operation needs.

[0036] In some embodiments, the diameter of the flexible water pipe 432 is set to half the diameter of the PE water pipe 21 to ensure that the limiting groove 4311 formed after filling with water can effectively accommodate the PE water pipe 21 while avoiding excessive compression. The width of the limiting groove 4311 is greater than or equal to the diameter of the PE water pipe 21, ensuring that the PE water pipe 21 can move freely within the groove but will not come out. The membrane tape body 431 includes a PE membrane tape, and the bonding area 433 is formed on the membrane tape body 431 in the axial direction by adhesive or stitching, which has good sealing performance and structural strength.

[0037] In conjunction with the above embodiments, this invention, by setting up a traveling film-laying box 40 and its protective film belt 43, achieves complete isolation between the PE water pipe 21 and the ground during the winding process. One end of the protective film belt 43 is fixed to the self-propelled trolley 30 and located directly below the spray gun 31, while the other end is synchronously wound by the film belt reel 42 at the same winding speed as the PE water pipe 21. This ensures that the PE water pipe 21 between the self-propelled trolley 30 and the reel 20 is always supported by the protective film belt 43, preventing direct contact and friction between the PE water pipe 21 and rough media such as gravel and soil on the ground. This solves the problem of pipe wall wear caused by dragging and extends the service life of the PE water pipe 21. At the same time, the two flexible water pipes 432 installed inside the protective film belt 43 expand when filled with water, causing the film belt body 431 to form symmetrical limiting protrusions 4312 and limiting... The PE water pipe 21 is precisely accommodated within the positioning groove 4311 and is effectively constrained by the limiting protrusions 4312 on both sides, thus automatically positioning itself during the winding process. This prevents rolling deviation caused by uneven ground or fluctuations in traction force, ensuring the orderly winding of the PE water pipe 21. When the protective membrane belt 43 enters the housing 41 for winding, the extrusion roller 44 rolls the membrane belt, and with the directional drainage function of the one-way pressure relief valve 4321, the water in the flexible water pipe 432 is gradually discharged towards the spray gun 31. The protective membrane belt 43 smoothly transitions from a water-filled state to a flat state, which not only releases the PE water pipe 21 but also facilitates the tight winding of the membrane belt. At the same time, the scraper 45 closely adheres to the bottom surface of the membrane belt, effectively scraping away dirt, moisture, and other impurities attached to the membrane belt, preventing impurities from being rolled into the membrane belt roll 42, and ensuring the cleanliness and neatness of the winding.

[0039] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
