[0002] Sprinkler irrigation is an advanced irrigation technology. It has the advantages of saving water, labor, land, increasing production and strong adaptability. There are many ways to classify sprinkler irrigation systems. For example, according to the spraying characteristics, there are fixed spray and row spray. Fixed spray is divided into pipeline type and unit type. Row spray is divided into center pivot type, translation type and reel type. Among them, reel sprinkler is the leader in irrigation machinery. It can provide economical and reliable services and is the best choice for irrigating field crops. Reel sprinkler refers to a sprinkler that is supplied with water by a hose, wound with a reel, and pulls a long-range sprinkler head so that the sprinkler head moves along the operation route during the sprinkler irrigation process. Its sprinkler carriage can move and stop automatically during the spraying process. It is simple to manage, easy to operate, labor-saving, and has low labor intensity. It is often used for the cultivation of vegetables, flowers, rice, fruit trees, grapes, hops or seaweed and watering in forestry.

The chassis-less reel sprinkler can realize the convenience of self-loading or unloading under the premise of greatly reducing the overall center of gravity of the reel sprinkler, and can avoid the situation that the crops in the field are excessively crushed. When the existing reel sprinkler is releasing the pipe, when the nozzle carriage is too fast away from the pipe release tray carriage, the speed of the pipe release cannot keep up, resulting in the problem of the water pipe being pulled, which affects the use of the reel sprinkler, so a reel sprinkler adaptive speed regulating device is proposed to solve the above-mentioned problems.

[0020] The present invention adopts the above technical solution to bring the following beneficial effects:

[0021] 1. The adaptive speed regulating device of the reel-type sprinkler irrigation machine cooperates with the base, roller, top seat, fixed plate, guide rod, lifting plate, distance sensor, sensing module, limit rod, limit block and spring to operate. When the moving speed of the sprinkler carriage is greater than the pipe-releasing speed of the pipe-releasing disc, the water pipe will change from a relaxed state to a tightened state. At this time, the water pipe will lift the lifting plate upward due to being straightened. At this time, the sensing module is close to the distance sensor, and its distance sensor will transmit the signal to the controller in the drive box, so that its drive motor drives to increase the pipe-releasing speed of the pipe-releasing disc, thereby achieving the purpose of automatic speed adjustment, avoiding the problem of pipe pulling caused by slow pipe-releasing speed, and improving the efficiency of sprinkler irrigation for vegetable planting.

[0022] 2. The adaptive speed regulating device of the reel-type sprinkler irrigation machine operates through the cooperation between the first bearing, the rotating column, the connecting frame, the guide port, the adjusting seat, the second bearing, the roller, the limit seat and the connecting shaft. When the nozzle carriage is offset from the carriage of the pipe tray during movement, the water pipe will contact the roller to make its base move along the guide port. At the same time, its base will deflect left and right relative to the adjusting seat, thereby achieving the purpose of adaptive adjustment, facilitating the release of the water pipe, and further improving the flexibility of the device for sprinkler irrigation of vegetable planting.

[0023] 3. The adaptive speed regulating device of the reel-type sprinkler operates through the cooperation among the device frame, the bidirectional screw, the turning handle, the first clamping plate, the second clamping plate, the rubber sheet, the rotating shaft and the rubber wheel. When the reel-type sprinkler is not in use or transported, the staff can drive the bidirectional screw to rotate by turning the turning handle, so that the first clamping plate and the second clamping plate clamp and fix the rubber wheel, so that the rotating shaft cannot rotate, so that the pipe release plate is locked and cannot rotate, avoiding the problem of the water pipe becoming tangled due to the rotation of the pipe release plate by external force, and facilitating the locking of the pipe release plate after the sprinkler pipes for vegetable planting are collected.

[0024] 4. The adaptive speed regulating device of the reel-type sprinkler irrigation machine, when the water pipe is stretched too quickly, the water pipe will be in a state of rising and straightening under the lifting plate, and the lifting plate will apply a buffering force to the water pipe through the lifting plate under the action of the spring, thereby avoiding the water pipe from being stretched too quickly due to excessive pulling force, resulting in the water pipe being stretched straight and damaged, thereby increasing the service life of the water pipe.

[0025] 5. The adaptive speed regulating device of the reel-type sprinkler can also be used by the staff to rotate the handle to clamp the rubber wheel with the first and second clamping plates when the motor drives the reel to release the pipe too fast, so as to increase the resistance to the rotation of the reel, thereby preventing the reel from releasing or collecting the pipe too fast when driven by the motor.

[0026] 6. The reel-type sprinkler has an adaptive speed regulating device. When the water pipe needs to be reeled in, the staff can place the pipe section in the cleaning rack between the two push rods, and then turn the handle to lower the adjustment plate so that the upper and lower brush plates contact the outer wall of the water pipe, and then start the servo motor to drive the moving seat to reciprocate. At this time, the outer pipe wall of the water pipe will be cleaned by the two brush plates during the reeling process. At the same time, due to the reciprocating push of the push rod, the water pipe will be wound back and forth at both ends on the pipe reel, avoiding the water pipe being wound in the same place, resulting in the problem of pipe jamming and winding in the later stage.

[0027] 7. The adaptive speed regulating device of the reel-type sprinkler irrigation machine, when the motor drives the pipe-releasing reel to release the pipe, the two plum blossom rollers can rotate along with the process of releasing the pipe, and the two plum blossom rollers squeeze the water pipe by rotating, thereby crushing the ice inside the water pipe. The two driven frames can also drive the two plum blossom rollers to slide horizontally along with the water pipe, so that the two plum blossom rollers can still maintain the ice crushing effect during the movement of the water pipe. After the ice in the water pipe is crushed, the possibility of pipe blockage is reduced, and the crushed ice can be discharged from the water pipe faster, avoiding the risk of a small amount of water stored in the water pipe 7 due to the last use when used in cold weather, and causing pipe blockage after the stored water freezes, so that the water pipe 7 is at risk of bursting when releasing water.

When the moving speed of the nozzle carriage is greater than the pipe-releasing speed of the pipe-releasing plate 6, the water pipe 7 at this time will change from a relaxed state to a stretched state.

The sensing module 208 is close to the distance sensor 207, and the distance sensor 207 transmits a signal to the controller in the driving box 8, so that the driving motor drives the controller to increase the pipe-releasing speed of the pipe-releasing plate 6, thereby achieving the purpose of automatic speed adjustment, avoiding the problem of pipe pulling caused by slow pipe-releasing speed, and improving the efficiency of sprinkler irrigation for vegetable planting. When the water pipe 7 is stretched too fast, the water pipe 7 will be in a state of rising and straightening under the lifting plate 206, and the lifting plate 206 will apply a buffering force to the water pipe 7 through the lifting plate 206 under the action of the spring 211, thereby avoiding the water pipe 7 from being stretched too fast due to excessive pulling force, resulting in the water pipe 7 being stretched straight and damaged, thereby improving the service life of the water pipe 7;

The connecting shaft 309 is fixedly mounted on the bottom of the base 201. When the nozzle carriage is offset from the carriage of the pipe placing plate 6 during movement, its water pipe 7 will contact the rotating roller 202, causing its base 201 to move along the guide port 304. At the same time, its base 201 deflects left and right relative to the adjusting seat 305, thereby achieving the purpose of adaptive adjustment, facilitating the placement of the water pipe 7, and further improving the flexibility of the device for sprinkler irrigation of vegetable planting.

[0049] A through hole is provided on the fixing plate 204, and the upper end of the guide rod 205 passes through the interior of the through hole. A limit block 210 is fixedly installed on the upper end of the guide rod 205.

The setting of the rollers 307 can facilitate the movement of the adjustment seat 305 on the base frame 5.

[0054] Working principle: When the moving speed of the nozzle carriage is greater than the tube-releasing speed of the tube-releasing plate 6, the water pipe 7 will change from a relaxed state to a tightened state. At this time, the water pipe 7 will be straightened, which will cause the water pipe 7 to lift the lifting plate 206 upward. At this time, the sensing module 208 is close to the distance sensor 207, and its distance sensor 207 will transmit the signal to the controller in the drive box 8, so that its drive motor drives to increase the tube-releasing speed of the tube-releasing plate 6, thereby achieving the purpose of automatic speed adjustment and avoiding the problem of tube pulling caused by slow tube-releasing speed. When the water pipe 7 is stretched too fast, the water pipe 7 will be in a position below the lifting plate 206. The lifting plate 206 is in a state of rising and straightening, and the lifting plate 206 applies a buffering force to the water pipe 7 through the lifting plate 206 under the action of the spring 211, so as to avoid the water pipe 7 being stretched too quickly and being subjected to excessive pulling force, resulting in the water pipe 7 being stretched straight and damaged, thereby improving the service life of the water pipe 7. When the nozzle carriage is offset from the carriage of the pipe placing plate 6 during movement, the water pipe 7 will contact the roller 202, so that the base 201 moves along the guide port 304, and at the same time, the base 201 deflects left and right relative to the adjustment seat 305, so as to achieve the purpose of adaptive adjustment and facilitate the placing of the water pipe 7.

[0056] The bidirectional screw 402 is threadedly connected with a first clamping plate 404, the bidirectional screw 402 is threadedly connected with a second clamping plate 405, the lower end of the bidirectional screw 402 is fixedly installed with a turning handle 403, and the device frame 401 is fixedly installed on the fixing frame 1. The setting of the turning handle 403 can facilitate the staff to rotate the bidirectional screw 402. When the reel-type sprinkler is not in use or transported, the staff can drive the bidirectional screw 402 to rotate by turning the turning handle 403, so that the first clamping plate 404 and the second clamping plate 405 clamp and fix the rubber wheel 408, so that the rotating shaft 407 cannot rotate, so that the tube-releasing disc 6 is locked and cannot rotate, avoiding the problem that the water pipe 7 becomes tangled due to the rotation of the tube-releasing disc 6 by external force, and conveniently locking the tube-releasing disc 6 after collecting the pipes for sprinkler irrigation of vegetable planting. When the tube-releasing speed of the tube-releasing disc 6 driven by the motor is too fast, the staff can also turn the handle 403 so that the first clamping plate 404 and the second clamping plate 405 clamp the rubber wheel 408 to increase the resistance to the rotation of the tube-releasing disc 6, thereby preventing the tube-releasing or tube-collecting speed of the tube-releasing disc 6 driven by the motor from being too fast.

The arrangement of the rubber sheet 406 and the rubber wheel 408 can increase the friction between the two, so that the rotating shaft 407 is fixed more stably.

[0058] Working principle: When the reel-type sprinkler is not in use or transported, the staff can drive the bidirectional screw 402 to rotate by turning the handle 403, so that the first clamping plate 404 and the second clamping plate 405 clamp and fix the rubber wheel 408, so that the rotating shaft 407 cannot rotate, thereby locking the pipe-releasing disc 6 and preventing the pipe-releasing disc 6 from being tangled due to the rotation of the external force, and avoiding the problem of the water pipe 7 becoming tangled due to the external force. When the pipe-releasing disc 6 driven by the motor is too fast, the staff can also turn the handle 403 so that the first clamping plate 404 and the second clamping plate 405 clamp the rubber wheel 408 to increase the resistance to the rotation of the pipe-releasing disc 6, thereby preventing the pipe-releasing disc 6 from releasing or collecting the pipe too fast under the drive of the motor.

The interior of the cleaning frame 901 is rotatably connected with a first screw rod 903 through a bearing, and the adjusting plate 902 is threadedly connected to the first screw rod 903. A light rod 905 is fixedly installed inside the cleaning frame 901, and the adjusting plate 902 is slidably connected to the light rod 905. The recovered water pipe 7 can be cleaned by setting the cleaning guide mechanism 9, and the water pipe 7 can also be reciprocated along the two ends of the pipe-releasing disk 6 to avoid uneven winding of the water pipe 7, which leads to the problem of entanglement of the pipe in the later stage and affects the pipe release;

[0060] The cleaning frame 901 is internally fixedly connected with a second brush plate 907, the bottom of the adjusting plate 902 is fixedly connected with a first brush plate 906, the upper end of the first screw 903 is fixedly connected with a handle 904, and the water pipe 7 passes through between the first brush plate 906 and the second brush plate 907. The second brush plate 907 and the first brush plate 906 can be used to clean the water pipe 7 during the winding process to prevent dirt such as leaves and soil from adhering to the water pipe 7;

[0061] A servo motor 908 is fixedly connected to the cleaning frame 901, and a second screw 909 is fixedly connected to the output end of the servo motor 908. A moving seat 910 is threadedly connected to the second screw 909. The side wall of the moving seat 910 is in contact with the cleaning frame 901. By starting the servo motor 908, the moving seat 910 can be driven to reciprocate along the second screw 909;

[0062] There are two push rods 911 fixedly connected to the movable seat 910. Both push rods 911 are fixedly connected to the movable seat 910, and the distance between the two push rods 911 is greater than the diameter of the water pipe 7. The arrangement of the push rods 911 can facilitate the movable seat 910 to drive the water pipe 7 to move.

[0063] Working principle: when the water pipe 7 needs to be rolled up, the staff can place the pipe section in the cleaning rack 901 between the two push rods 911, and then turn the handle 904 to lower the adjustment plate 902, so that the upper and lower brush plates are in contact with the outer wall of the water pipe 7, and then start the servo motor 908 to drive the moving seat 910 to reciprocate. At this time, the outer pipe wall of the water pipe 7 will be cleaned by the two brush plates during the winding process. At the same time, due to the reciprocating push of the push rod 911, the water pipe 7 will be wound back and forth at both ends on the pipe tray 6, avoiding the water pipe 7 from winding in the same place, resulting in the problem of pipe jamming and winding when the pipe is discharged later.

[0064] See also Figure 12-13 On the basis of the above embodiment, in another embodiment of the present invention, an ice crushing mechanism 10 is provided on the fixing frame 1, and the ice crushing mechanism 10 includes two mounting frames 1004, and the two mounting frames 1004 are both mounted on the cleaning frame 901, and two flat key shafts 1005 are rotatably connected to the two mounting frames 1004, and a cam 1001 is connected to the rotating shaft 407, and a slide frame 1002 is slidably installed on the fixing frame 1, and the cam 1001 is slidably connected to the inner wall of the slide frame 1002 through a bearing, and a rack 1003 is connected to the slide frame 1002, and one end of the two flat key shafts 1005 is respectively connected to a gear 1006, and the two gears 1006 are meshed with the rack 1003, and the outer wall of the flat key shaft 1005 is slidably connected to a plum blossom roller 1007, and the flat key shaft 100 5 is provided with two long keys, and the inner wall of the plum blossom roller 1007 is provided with two key grooves, and the two key grooves in the plum blossom roller 1007 are respectively meshed with the long keys on the flat key shaft 1005, and the two ends of the two plum blossom rollers 1007 are respectively rotatably connected with the driven frames 1008, and the two flat key shafts 1005 respectively drive the two plum blossom rollers 1007 to rotate through the cooperation of the long keys and the key grooves, so that the two plum blossom rollers 1007 can rotate between the two driven frames 1008, and the water pipe 7 is located between the two driven frames 1008 and the two plum blossom rollers 1007. Since the spacing between the two plum blossom rollers 1007 is smaller than the outer diameter of the water pipe 7, the two plum blossom rollers 1007 can squeeze the water pipe 7 when rotating, thereby crushing the crushed ice in the water pipe 7, so that the ice cubes can be quickly discharged, reducing the probability of ice cubes blocking the water pipe 7, and playing a role in protecting the water pipe 7.

[0065] Working principle: When the rotating shaft 407 rotates, the cam 1001 rotates. The cam 1001 drives the slide frame 1002 to move up and down through the bearing. The slide frame 1002 drives the rack 1003 to move up and down. When the rack 1003 moves, it drives the two flat key shafts 1005 to rotate through the two gears 1006. The two flat key shafts 1005 respectively drive the two plum blossom rollers 1007 to rotate through the cooperation of the long key and the keyway, so that the two plum blossom rollers 1007 can rotate between the two driven frames 1008. The water pipe 7 is located between the two driven frames 1008 and the two plum blossom rollers 1007. Since the spacing between the two plum blossom rollers 1007 is smaller than the outer diameter of the water pipe 7, the two plum blossom rollers 1007 can squeeze the water pipe 7 when rotating, thereby crushing the crushed ice in the water pipe 7; when the water pipe 7 moves horizontally, the water pipe 7 drives the two plum blossom rollers 1007 through the two driven frames 1008, so that the two plum blossom rollers 1007 can slide on the two flat key shafts 1005 while rotating, thereby achieving the effect that the two plum blossom rollers 1007 can slide along with the water pipe 7 and continuously maintain the ice crushing effect.
