Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of the traction of sprinkler machines, and in particular to a special traction device for sprinkler machines. BACKGROUND

[0002] Sprinkler machines are widely used in the sprinkling operation of large areas of land. The working principle is to move the sprinkling frame by the traction frame, and in this process, the sprinkling pipeline on the sprinkling frame will carry out the sprinkling operation. However, in the traditional way, the traction frame needs to be guided manually to ensure that it travels along the predetermined route (usually a straight line). When pulling, the traction device (such as a tractor) is used to pull the traction frame, but due to the large size of the traction device, it will cause the rolling of the crops on the land during the travel process, and it is time-consuming and laborious to operate.

[0003] At present, a new traction method has been introduced, that is, a winding rope is used to pull the traction frame. This method uses a fixedly arranged winding wheel to wind the winding rope, thereby pulling the traction frame. This method not only effectively reduces the damage to the crops, but also has the advantages of rapid guidance and convenient construction.

[0004] However, relevant workers found that the above-mentioned method controls the movement of the traction frame, and when the road surface is uneven or undulating, it will cause the traction frame to travel unstably. This instability will further cause the sprinkling pipeline carried on the traction frame to shake, thereby adversely affecting the irrigation effect. In addition, if you want to maintain the stable operation of the traction frame, you have to limit its travel speed, which will inevitably reduce the irrigation efficiency. SUMMARY

[0005] The present application aims to at least solve one of the technical problems in the related art to some extent.

[0006] To this end, one purpose of the present application is to provide a special traction device for sprinkler machines, which can correct the traction angle of the traction frame in real time through the traction mechanism, so that the two winding ropes are consistent with the travel direction of the traction frame, thereby realizing the stable and efficient travel of the traction frame, and thereby improving the irrigation effect and efficiency.

The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0031] The special traction device for sprinkler of the embodiments of the present application is described below in combination with the drawings.

[0032] As shown in the drawings, Figures 1-6 The special traction device for sprinkler of the embodiments of the present application can include a traction frame 10 and a traction mechanism.

[0033] The traction frame 10 can move, and the traction frame 10 is provided with a traction part 11.

[0034] In the embodiments of the present application, the traction frame 10 is used to carry the sprinkler pipeline on the sprinkler, and the sprinkler pipeline can irrigate crops during the movement of the traction frame 10.

The winding wheel 30 is provided on the frame 20 through a driving assembly 60. The outer side of the winding wheel 30 is provided with a baffle 31. One end of each of the two winding ropes 40 is wound around the two sides of the winding wheel 30, and the two winding ropes 40 are located on the two sides of the baffle 31, respectively.

[0036] It should be noted that the lifting part 21 described in this embodiment can be a pneumatic cylinder, a scissor lift, etc. The lifting part 21 has the function of controlling the lifting of the frame 20, so as to adjust the height of the two winding ropes 40 on the frame 20.

[0037] The connecting piece 50 can include a connecting frame 51, a linear guide rail 52, and an angle measuring piece 53, which are sequentially arranged.

The linear guide rail 52 is slidably provided with two symmetrically arranged second moving pieces 522. The other end of each of the two winding ropes 40 passes through the angle measuring piece 53 and is connected with the corresponding second moving piece 522.

[0038] The angle measuring member 53 can include a housing 531, a rotating shaft 532, an axle encoder 533 and a pointer frame 534, wherein the housing 531 is connected to the middle part of the linear guide rail 52, the rotating shaft 532 is movably arranged in the housing 531, the rotating shaft 532 is connected to the axle encoder 533, one end of the pointer frame 534 penetrates through the housing 531 and is fixedly connected to the rotating shaft 532, and the other end of the pointer frame 534 is provided with a through hole for winding the rope 40, and the through hole can be symmetrically provided with two through holes for two winding ropes 40, and the winding rope 40 can move in the corresponding through hole.

[0039] When the angle of the winding rope 40 is measured by the angle measuring member 53, specifically, for example, when encountering a slope, the slope of the traction frame 10 will change, and the angle between the traction part 11 and the winding wheel 30 will change, and the two winding ropes 40 will drive the pointer frame 534 to correspondingly change the rotation, and the pointer frame 534 drives the rotating shaft 532 to correspondingly change the rotation, and the change is recorded by the axle encoder 533 and fed back to the relevant personnel, and the relevant personnel adjusts the height of the rack 20 according to the change, so as to ensure that the winding rope 40 is consistent with the direction of the traction frame 10, thereby ensuring the traction effect of the traction frame 10.

[0040] It should be noted that the axle encoder 533 described in this embodiment has the function of recording the change of the rotation of the rotating shaft 532 in real time, and can record and feed back the change to the relevant personnel. Specifically, a display can be separately configured to directly present the change of the rotation of the rotating shaft 532 to the relevant personnel. In addition, the axle encoder 533 belongs to the prior art, and will not be described here.

[0041] The linear guide rail 52 movably arranged therein is provided with a second rotating roller 521, and the two sides of the second rotating roller 521 are symmetrically provided with a second reciprocating spiral groove 5211, and two second moving members 522 are respectively engaged with the corresponding second reciprocating spiral grooves 5211, and the connecting frame 51 movably arranged therein is provided with a linkage shaft 512, and the linkage shaft 512 and the center shaft of the auxiliary wheel 511 are connected through a first synchronous belt 71, and the linkage shaft 512 and the second rotating roller 521 are connected through a second synchronous belt 72.

[0042] In the embodiment of the application, the linkage shaft 512, the second rotating roller 521 and the center shaft of the auxiliary wheel 511 can be correspondingly provided with synchronous wheels, so that the first synchronous belt 71 and the second synchronous belt 72 can smoothly run.

[0043] It should be noted that the drive assembly 60 described in this embodiment has the function of controlling the rotation of the winding wheel 30. Specifically, the drive assembly 60 can include a servo motor 61, a first chain 62 and two first chain wheels 63. The servo motor 61 is arranged on the rack 20, and its output end is fixedly connected with one of the first chain wheels 63. The other first chain wheel 63 is sleeved on one end of the winding wheel 30. The first chain 62 is sleeved on the outer sides of the two first chain wheels 63. After the servo motor 61 is started, the first chain wheel 63 connected with it rotates. Under the action of the first chain 62, the other first chain wheel 63 drives the winding wheel 30 to rotate synchronously.

[0044] The rack 20 is provided with a rope arranging assembly 80. The rope arranging assembly 80 can include a first rotating roller 81, a guide rail 82 and two first moving members 83. The first rotating roller 81 and the guide rail 82 are parallel and movably arranged on the rack 20. The first rotating roller 81 is symmetrically provided with first reciprocating spiral grooves 811 on both sides. The outer sides of the first rotating roller 81 and the winding wheel 30 are provided with second chain wheels 812. The outer sides of the two second chain wheels 812 are sleeved with a second chain 813. The second chain wheels 812 and the second chain 813 are arranged to enable the first rotating roller 81 to rotate synchronously with the winding wheel 30, thereby saving the driving source.

[0045] The two first moving members 83 are symmetrically arranged. One end of each of the two first moving members 83 is engaged with the corresponding first reciprocating spiral groove 811. The other end of each of the two first moving members 83 is slidably connected with the guide rail 82. The winding rope 40 passes through the corresponding first moving member 83. Specifically, the inner side of each first moving member 83 is movably provided with two pulleys 831. The winding rope 40 passes between the corresponding two pulleys 831. When the winding rope 40 is wound outside the winding wheel 30, the pulley 831 can be driven to rotate, thereby reducing the friction between the winding rope 40 and the corresponding first moving member 83.

[0046] It should be noted that the first reciprocating spiral groove 811 and the corresponding first moving part 83, the second reciprocating spiral groove 5211 and the corresponding second moving part 522 described in this embodiment are all designed in a similar matching reciprocating screw rod and nut (or slider) connected on the reciprocating screw rod. The length of the first rotating roller 81 and the second rotating roller 521 is 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 move reciprocally symmetrically. Similarly, the two second moving parts 522 can move reciprocally symmetrically, so that the two first moving parts 83 and the two second moving parts 522 can be used to accurately control the travel route of the winding rope 40, ensuring that the two winding ropes 40 always maintain a parallel state during the entire traction process. This design greatly optimizes the traction efficiency of the traction frame 10.

[0047] In the embodiments of the present application, the guide rail 82 is a linear guide rail, which can guide the first moving part 83 and prevent the first moving part 83 from rotating.

[0048] Specifically, when the traction frame 10 needs to be walked and pulled, the relevant personnel first perform preparation work, install the sprinkler pipeline on the sprinkler machine on the traction frame 10, then place the traction frame 10 and the rack 20 at both ends of the land respectively, then move the connecting piece 50 to the traction frame 10, connect one end of the connecting frame 51 with the traction part 11, and place the auxiliary wheel 511 on the land.

[0049] After the preparation work is completed, the relevant personnel start the servo motor 61, and under the action of the first chain 62 and the two first sprockets 63, the winding wheel 30 rotates, and 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 in the area on both sides of the winding wheel 30 respectively, and at the same time, under the traction of the two winding ropes 40, the traction frame 10 moves along the direction of the winding rope 40, and during the process, the sprinkler pipeline on the traction frame 10 performs sprinkling operation on the crops on the land.

[0050] The auxiliary wheel 511 moves with the traction frame 10, and the center shaft of the auxiliary wheel 511 can drive the linkage shaft 512 to rotate through the first synchronous belt 71, and 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 move reciprocally correspondingly.

[0051] When encountering a slope, the slope of the traction frame 10 will change accordingly, and the angle between the traction part 11 and the winding wheel 30 will change accordingly, and the two winding ropes 40 will drive the pointer frame 534 to change correspondingly, and the pointer frame 534 drives the rotating shaft 532 to change correspondingly, and the change is recorded by the shaft encoder 533 and fed back to the relevant personnel, and the relevant personnel adjust the height of the machine frame 20 according to the change, so as to ensure that the winding rope 40 and the advancing direction of the traction frame 10 are consistent, thereby ensuring the traction effect of the traction frame 10.

[0052] In summary, the special traction device for the sprinkler of the embodiment of the present application, on the one hand, adopts two symmetrically arranged winding ropes for synchronous operation to jointly implement traction operation on the traction frame; on the other hand, through the cooperation of the angle measuring element and the liftable machine frame, the advancing direction of the winding rope and the traction frame is always kept consistent, thereby comprehensively ensuring the high-quality traction effect on the traction frame.
