Description

Technical Field

[0001] This application relates to the technical field of sprinkler machine traction, and more particularly to a dedicated traction device for sprinkler machines. Background Technology

[0002] Sprinkler irrigation machines are widely used for large-area irrigation operations. Their working principle involves a tow frame that moves the sprinkler system, during which the irrigation pipes on the frame spray water. However, traditionally, the tow frame requires manual guidance to ensure it travels along a predetermined route (usually a straight line). Towing requires the use of traction equipment (such as a tractor), but because the traction equipment is large, it can cause damage to crops during movement, and the operation is time-consuming and labor-intensive.

[0003] Currently, a new traction method has been introduced, which uses a winding rope to pull the traction frame. This method involves a fixed winding wheel winding the rope, thereby pulling the traction frame. This approach not only effectively reduces damage to crops but also offers advantages such as rapid guidance and convenient construction.

[0004] However, staff discovered that this method of controlling the tow frame's movement caused instability on uneven or undulating surfaces. This instability further caused the sprinkler pipes mounted on the tow frame to sway, thus negatively impacting irrigation efficiency. Furthermore, maintaining stable operation of the tow frame necessitates limiting its speed, which inevitably reduces irrigation efficiency. Summary of the Invention

[0005] This application aims to at least partially address one of the technical problems in the related art.

[0006] Therefore, one objective of this application is to provide a dedicated traction device for sprinkler irrigation machines. Through the traction mechanism, the traction angle of the traction frame can be corrected in real time, so that the two winding ropes are consistent with the travel direction of the traction frame, thereby achieving stable and efficient travel of the traction frame, and thus improving irrigation effect and efficiency.

[0007] To achieve the above objectives, a first aspect of this application provides a dedicated traction device for sprinkler irrigation machines, comprising a traction frame and a traction mechanism. The traction frame is movable and has a traction section. The traction mechanism includes a frame, a winding wheel, two winding ropes, and a connecting member. The frame is liftable. The winding wheel is mounted on the frame via a drive assembly, and a baffle is fitted around its outer side.

The connecting member includes a connecting frame, a linear guide rail, and an angle measuring component arranged sequentially. One end of the connecting frame is detachably connected to the traction section, and an auxiliary wheel is located below the connecting frame. Two symmetrically arranged second moving parts slide on the linear guide rail. The other end of each winding rope passes through the angle measuring component and is connected to the corresponding second moving part.

[0008] In addition, the special traction device for sprinkler irrigation machines proposed in this application may also have the following additional technical features: In one embodiment of this application, the angle measuring device includes a housing, a rotating shaft, a shaft encoder, and a pointer holder, wherein the housing is connected to the middle of the linear guide rail; the rotating shaft is movably disposed within the housing and is connected to the shaft encoder; one end of the pointer holder passes through the housing and is fixedly connected to the rotating shaft, and the other end of the pointer holder is provided with a through hole for the winding rope to pass through.

[0009] In one embodiment of this application, a second rotating roller is movably provided inside the linear guide rail, and second reciprocating spiral grooves are symmetrically arranged on both sides of the second rotating roller, and two second moving parts respectively mesh with the corresponding second reciprocating spiral grooves.

[0010] In one embodiment of this application, a linkage shaft is movably provided on the connecting frame, the linkage shaft and the central shaft of the auxiliary wheel are connected by a first synchronous belt, and the linkage shaft and the second rotating roller are connected by a second synchronous belt.

[0012] In one embodiment of this application, the frame is provided with a rope-laying assembly, which includes a first rotating roller, a guide rail, and two first moving parts. The first rotating roller and the guide rail are parallel and are movably mounted on the frame. The first rotating roller has symmetrically arranged first reciprocating spiral grooves on both sides, and the first rotating roller and the take-up roller are each provided with a second sprocket on their outer sides. A second chain is sleeved on the outer side of the two second sprockets. The two first moving parts are symmetrically arranged, and one end of each of the two first moving parts is engaged with the corresponding first reciprocating spiral groove, while the other end of each of the two first moving parts is slidably connected to the guide rail. The take-up rope passes through the corresponding first moving part.

[0013] In one embodiment of this application, two pulleys are movably provided on the inner side of the first movable member, and the winding rope passes between the corresponding two pulleys.

[0014] In one embodiment of this application, a lifting component and a base are sequentially connected to the bottom of the frame, wherein a ground fork is movably connected through the base.

Detailed Implementation

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0021] The following describes the special traction device for sprinkler irrigation machines according to embodiments of this application, with reference to the accompanying drawings.

[0022] like Figures 1-6 As shown, the sprinkler machine traction device of this application embodiment may include a traction frame 10 and a traction mechanism.

[0023] The traction frame 10 is movable and is equipped with a traction unit 11.

[0024] In this embodiment, the traction frame 10 is used to support the irrigation pipes on the sprinkler irrigation machine. During the movement of the traction frame 10, the irrigation pipes can irrigate the crops. The traction part 11 can be configured as a hole, and the traction part 11 and the connecting frame 51 can be quickly and easily fixed together by a connecting rope.

[0025] The traction mechanism may include a frame 20, a take-up reel 30, two take-up ropes 40, and a connector 50. The frame 20 is height-adjustable, and a lifting component 21 and a base 22 are sequentially connected to the bottom of the frame 20. The base 22 has a fork 23 that can be movably inserted through it. Sockets 221 are provided at the four corners of the top of the base 22. A rod 201 is provided at the bottom of the frame 20, and the lower side of the rod 201 is movably inserted into the corresponding socket 221. The rod 201 can be raised and lowered synchronously with the frame 20, and the socket 221 can limit the movement of the rod 201 during the process. The take-up reel 30 is mounted on the frame 20 via a drive assembly 60. A baffle 31 is fitted around the outside of the take-up reel 30. One end of each of the two take-up ropes 40 is wound around both sides of the take-up reel 30, and the two take-up ropes 40 are located on both sides of the baffle 31.

[0026] It should be noted that the lifting component 21 described in this embodiment can be a cylinder, a scissor lift, etc. The lifting component 21 has the function of controlling the lifting of the frame 20, thereby adjusting the height of the two winding ropes 40 on the frame 20.

[0027] The connector 50 may include a connecting frame 51, a linear guide rail 52, and an angle measuring component 53 arranged sequentially. One end of the connecting frame 51 is detachably connected to the traction unit 11, and an auxiliary wheel 511 is provided below the connecting frame 51. Two symmetrically arranged second moving parts 522 are slidably arranged on the linear guide rail 52. The other end of each winding rope 40 passes through the angle measuring component 53 and is connected to the corresponding second moving part 522.

[0028] The angle measuring component 53 may include a housing 531, a rotating shaft 532, a shaft encoder 533, and a pointer holder 534. The housing 531 is connected to the middle of the linear guide rail 52. The rotating shaft 532 is movably disposed inside the housing 531 and is connected to the shaft encoder 533. One end of the pointer holder 534 passes through the housing 531 and is fixedly connected to the rotating shaft 532. The other end of the pointer holder 534 is provided with a through hole for the winding rope 40 to pass through. Two through holes may be symmetrically arranged, and the two through holes are respectively used for two winding ropes 40, and the winding ropes 40 can move in the corresponding through holes.

[0029] When the angle measuring device 53 measures the angle of the winding rope 40, specifically, for example, when encountering a slope, the slope of the traction frame 10 will change accordingly, and the angle between the traction unit 11 and the winding wheel 30 will change. The two winding ropes 40 will then drive the pointer frame 534 to rotate accordingly. The pointer frame 534 drives the rotating shaft 532 to rotate accordingly. This rotation change is recorded by the shaft encoder 533 and fed back to the relevant personnel. The relevant personnel adjust the height of the frame 20 according to this change, thereby ensuring that the winding rope 40 and the traction frame 10 travel in the same direction, thus ensuring the traction effect of the traction frame 10.

[0030] It should be noted that the shaft encoder 533 described in this embodiment has the function of recording the rotational changes of the rotating shaft 532 in real time, and can record this change and provide feedback to relevant personnel. Specifically, a separate display can be configured to visually present the rotational changes of the rotating shaft 532 to relevant personnel. Furthermore, the shaft encoder 533 is prior art and will not be described in detail here.

[0031] A second rotating roller 521 is movably provided inside the linear guide rail 52. Second reciprocating spiral grooves 5211 are symmetrically arranged on both sides of the second rotating roller 521. Two second moving parts 522 respectively mesh with the corresponding second reciprocating spiral grooves 5211. A linkage shaft 512 is movably provided on the connecting frame 51. The linkage shaft 512 and the central axis of the auxiliary wheel 511 are connected by a first synchronous belt 71. The linkage shaft 512 and the second rotating roller 521 are connected by a second synchronous belt 72.

[0032] In this embodiment, the central shafts of the linkage shaft 512, the second rotating roller 521, and the auxiliary wheel 511 can all be equipped with synchronous pulleys, so that the first synchronous belt 71 and the second synchronous belt 72 can operate smoothly.

[0033] It should be noted that the drive assembly 60 described in this embodiment has the function of controlling the rotation of the take-up reel 30. Specifically, the drive assembly 60 may include a servo motor 61, a first chain 62 and two first sprockets 63. The servo motor 61 is mounted on the frame 20 and its output end is fixedly connected to one of the first sprockets 63. The other first sprocket 63 is sleeved on one end of the take-up reel 30. The first chain 62 is sleeved on the outside of the two first sprockets 63. After the servo motor 61 is started, the first sprocket 63 connected to it rotates accordingly. Under the action of the first chain 62, the other first sprocket 63 drives the take-up reel 30 to rotate synchronously.

[0034] The frame 20 is equipped with a rope-laying assembly 80, which may include a first rotating roller 81, a guide rail 82, and two first moving parts 83. The first rotating roller 81 and the guide rail 82 are parallel and movably mounted on the frame 20. First reciprocating spiral grooves 811 are symmetrically arranged on both sides of the first rotating roller 81, and second sprockets 812 are provided on the outer sides of both the first rotating roller 81 and the take-up reel 30. Second chains 813 are sleeved on the outer sides of the two second sprockets 812. Through the arrangement of the second sprockets 812 and the second chains 813, the first rotating roller 81 can rotate synchronously with the take-up reel 30, thereby saving on the drive source.

[0035] Two first moving parts 83 are symmetrically arranged, with one end of each first moving part 83 engaging with a corresponding first reciprocating spiral groove 811, and the other end of each first moving part 83 slidably connected to a guide rail 82. A winding rope 40 passes through the corresponding first moving part 83. Specifically, two pulleys 831 are movably provided on the inner side of each first moving part 83, and the winding rope 40 passes between the corresponding two pulleys 831. When the winding rope 40 is wound around the outside of the winding wheel 30, it can drive the pulleys 831 to rotate, thereby reducing friction between the winding rope 40 and the corresponding first moving part 83.

[0036] It should be noted that, in this embodiment, the first reciprocating spiral groove 811 and the corresponding first moving part 83, and the second reciprocating spiral groove 5211 and the corresponding second moving part 522, are all connected by a similar matching reciprocating screw and a nut (or slider) on the reciprocating screw. The lengths of the first rotating roller 81 and the second rotating roller 521 are consistent. This design allows the two first moving parts 83 to slide on the corresponding first reciprocating spiral groove 811 after the first rotating roller 81 rotates, and the two first moving parts 83 can perform symmetrical reciprocating movements. Similarly, the two second moving parts 522 can perform symmetrical reciprocating movements. Thus, the two first moving parts 83 and the two second moving parts 522 can be used to precisely control the travel path of the winding rope 40, ensuring that the two winding ropes 40 remain parallel throughout the entire traction process. This design greatly optimizes the traction efficiency of the traction frame 10.

[0037] In this embodiment, the guide rail 82 is a linear guide rail, which can guide the first moving member 83 and prevent the first moving member 83 from rotating.

[0038] Specifically, when the towing frame 10 needs to be towed, the relevant personnel first make preparations by installing the sprinkler pipes on the sprinkler machine onto the towing frame 10, then placing the towing frame 10 and the frame 20 at opposite ends of the land, then moving the connector 50 to the towing frame 10, connecting one end of the connector 51 to the towing unit 11, and placing the auxiliary wheel 511 on the land.

[0039] After preparation, the relevant personnel start the servo motor 61. Under the action of the first chain 62 and the two first sprockets 63, the winding wheel 30 rotates. Under the action of the second chain 813 and the two second sprockets 812, the first rotating roller 81 rotates synchronously with the winding wheel 30. During the process, the two winding ropes 40 are wound up in the areas on both sides of the winding wheel 30. At the same time, under the traction of the two winding ropes 40, the traction frame 10 moves along the direction of the winding ropes 40. During the process, the sprinkler pipes on the traction frame 10 perform sprinkler irrigation on the crops on the land.

[0040] The auxiliary wheel 511 moves with the traction frame 10. During the process, the central axis of the auxiliary wheel 511 can drive the linkage shaft 512 to rotate through the first synchronous belt 71. Under the action of the second synchronous belt 72, the second rotating roller 521 can rotate synchronously and in the same direction with the linkage shaft 512, so that the two second moving parts 522 can perform corresponding reciprocating movements.

[0041] When encountering a slope, the slope of the traction frame 10 will change accordingly, and the angle between the traction unit 11 and the winding wheel 30 will change accordingly. The two winding ropes 40 will drive the pointer frame 534 to rotate accordingly. The pointer frame 534 drives the rotating shaft 532 to rotate accordingly. This rotation change is recorded by the shaft encoder 533 and fed back to the relevant personnel. The relevant personnel adjust the height of the frame 20 according to this change, so as to ensure that the winding rope 40 and the traction frame 10 are consistent in the direction of travel, thereby ensuring the traction effect of the traction frame 10 in all directions.

[0042] In summary, the dedicated traction device for sprinkler irrigation machines in this application embodiment employs two symmetrically arranged winding ropes that operate synchronously to jointly traction the traction frame. Furthermore, through the coordinated operation of the angle measuring device and the liftable frame, it ensures that the winding ropes and the traction frame always maintain a high degree of consistency in their direction of travel, thereby comprehensively guaranteeing a high-quality traction effect on the traction frame.
