DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, what is described is only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See Figure 1-6 , a high-efficiency spraying and disinfecting device for pastures, comprising: a vehicle body 1, a medicine supply mechanism and a spraying mechanism, wherein the medicine supply mechanism is arranged on the upper side of the vehicle body 1, and the spraying mechanism is arranged on the front side of the vehicle body 1;

[0030] The spraying mechanism includes a winding assembly, two sets of pipe assemblies and two sets of reversing assemblies. The ends of the two sets of pipe assemblies close to the vehicle body 1 are supported by two sets of reversing assemblies and are both connected to the winding assembly.

[0031] The pipeline assembly includes a conduit 2, multiple sets of protective components and multiple sets of limiting components. The protective components include a sleeve 3, a nozzle 4, a connecting pipe 5 and two first connecting plates 6. The nozzle 4 is fixedly sleeved in the side wall of the sleeve 3. The conduit 2 horizontally passes through the sleeve 3. The nozzle 4 and the conduit 2 are connected and communicated through the connecting pipe 5. The conduit 2 and the connecting pipe 5 are both made of hoses. The two first connecting plates 6 are symmetrically and horizontally fixedly installed on the outer end of the sleeve 3. The limiting components are set at the end of the sleeve 3 close to the vehicle body 1.

[0032] The end of the limiting component close to the vehicle body 1 is symmetrically and horizontally fixedly mounted with two second connecting plates 7, and the two first connecting plates 6 and the two second connecting plates 7 are hinged by a pin 8;

[0033] A rotorcraft device 9 is installed at the end of the outermost sleeve 3 to control the direction of the pipeline assembly.

[0034] The vehicle body 1 is an AGV intelligent vehicle with an electric energy device at the rear end for powering the entire device. A control module is provided on the vehicle body 1 for transmitting data with external terminal devices and controlling the overall operation of the device. The electric energy device, the control module, the related electrical equipment and their circuit connection relationships all belong to the existing technology and will not be elaborated here.

[0035] The limiting component includes a snap ring 10, multiple blocks 11 and multiple springs 12. The snap ring 10 is rotatably sleeved on one end of the sleeve 3 close to the vehicle body 1. Multiple sliding cavities 101 are provided in the snap ring 10. Multiple blocks 11 are respectively slidably sleeved in the multiple sliding cavities 101. Multiple springs 12 are respectively sleeved in the multiple sliding cavities 101, and both ends are fixedly connected to the inner wall of the sliding cavity 101 and the end of the block 11. Multiple grooves 301 are provided at the end of the sleeve 3. The block 11 is in sliding contact with the area of the sleeve 3 with the groove 301. After reversing, under the elastic force of the multiple springs 12, the block 11 is clamped with the groove 301, which can prevent the sleeve 3 from rotating, thereby ensuring that the nozzle 4 is vertically downward.

[0036] The winding assembly includes a turntable 13, a rotating tube 14, a frame 15 and a driving component. The frame 15 is vertically fixedly installed at the front end of the vehicle body 1, and the rotating tube 14 is horizontally rotatably sleeved in the frame 15. The turntable 13 is fixedly sleeved on the rotating tube 14. The turntable 13 is stepped. The sleeve 3 near the turntable 13 in the protective component is hinged to the turntable 13 through the second connecting plate 7. The input end of the catheter 2 is fixedly sleeved in the turntable 13 and is fixedly connected and conducted with the rotating tube 14. The input end of the rotating tube 14 is rotatably connected to the output end of the medicine feeding mechanism. The driving component is used to drive the turntable 13 to rotate. A plurality of blocking rods 29 are vertically fixedly installed on the outside of the turntable 13.

[0037] The driving component includes a motor 30, a first gear 31 and a second gear 32. The motor 30 is fixedly mounted on the front bottom of the vehicle body 1. The second gear 32 is fixedly sleeved on the turntable 13. The first gear 31 is fixedly sleeved on the output shaft of the motor 30 and is meshed with the second gear 32.

[0038] The reversing assembly includes a stand 16, two pressure rollers 17, a first ring body 18 and a second ring body 19. The stand 16 is vertically fixedly installed on the front side of the vehicle body 1. The two pressure rollers 17 are symmetrically installed on the front side of the stand 16 and are respectively located on the upper and lower sides of the sleeve 3, and are in rolling contact with the sleeve 3. The pressure roller 17 is made of a smooth material. The first ring body 18 and the second ring body 19 are both vertically fixedly installed on the upper bottom of the stand 16, and the first ring body 18 is close to the vehicle body 1. A ball 20 is rolledly embedded in the first ring body 18, and a guide groove 302 is opened on the outside of the sleeve 3. The ball 20 is in rolling contact with the guide groove 302. A plurality of rollers 21 are rolledly installed in the second ring body 19. The plurality of rollers 21 are all made of elastic material and are evenly distributed in a ring shape, and are in rolling contact with the outside of the sleeve 3.

[0039] The plurality of rollers 21 clamp the sleeve 3 so that it can only move in the horizontal direction without rotating, thereby ensuring that it is in a reversed state.

[0040] The medicine supply mechanism includes a box body 22 and a pump body 23. The box body 22 is placed in the vehicle body 1. The pump body 23 is fixedly installed on the front side of the vehicle body 1. The input end is fixedly connected to the output end of the box body 22, and the output end is rotatably connected to the rotating tube 14.

[0041] A distance measuring sensor device 24 is fixedly embedded in the outer wall of the sleeve 3. The sleeve 3 at the outermost end is hinged with a cross bar 25 through the first connecting plate 6 and the pin 8. A ball hinge device 26 is fixedly installed on the outer end of the cross bar 25. The rotorcraft device 9 is connected to the cross bar 25 through the ball hinge device 26. The rotorcraft device 9 can generate aerodynamic force under the control of the control module. With the support of the ball hinge device 26, the aerodynamic force is used to generate recoil effects in different directions, thereby driving the pipeline component to move and change its state.

[0042] An air hole 27 is formed at the front end of the vehicle body 1 , and a fan device 28 is fixedly installed in the air hole 27 .

[0043] When using this device, instructions are sent to the control module through an external terminal to control the overall operation of the device.

[0044] During operation, the motor 30 and the rotorcraft device 9 are started first, and the motor 30 drives the turntable 13 to rotate through the first gear 31 and the second gear 32 to release the two sets of pipe assemblies. The rotorcraft device 9 runs and cooperates with the rotation and release action of the turntable 13.

[0045] As the turntable 13 is released, the sleeve 3 moves outward. When passing through the first ring body 18, the guide groove 302 engages with the ball 20, and the sleeve 3 continues to move. Under the interference of the guide groove 302 and the ball 20, the sleeve 3 rotates. After the ball 20 disengages from the guide groove 302, the sleeve 3 rotates ninety degrees, so that the nozzle 4 is vertically downward and the distance sensing device 24 faces forward. When the sleeve 3 at the rear enters the first ring body 18 for reversing, the sleeve 3 that has just completed the reversal enters the second ring body 19 and contacts the multiple rollers 21. The multiple rollers 21 limit the sleeve 3 that has completed the reversal, so that it maintains the state after the reversal, that is, the nozzle 4 is vertically downward and the distance sensing device 24 is horizontally facing forward.

[0046] After the reversal is completed, the pin shafts 8 located outside the second ring body 19 are all in a vertical state, so that the multiple sleeves 3 can only swing in the horizontal plane, and the multiple sleeves 3 are in a straight and extended state, so that the multiple nozzles 4 are lined up in a row to cover the area that needs to be sprayed and disinfected.

[0047] After the multiple sleeves 3 are unfolded, the vehicle body 1 and the pump body 23 are started, the vehicle body 1 moves, and the two sets of pipeline components are mobilized to move. At the same time, the rotorcraft device 9 operates to generate aerodynamic force, driving the pipeline components and the vehicle body 1 forward synchronously, and at the same time generating upward lift to prevent the pipeline components from bending due to their own gravity and keep them straight.

[0048] As the vehicle body 1 moves, the pump body 23 operates, injecting liquid medicine into the two conduits 2 through the rotating pipe 14, and then the liquid medicine finally enters the corresponding nozzle 4 through multiple connecting pipes 5, and is sprayed out after being atomized by the nozzle 4 to achieve disinfection of the shed.

[0049] The pipeline assembly is unfolded in a straight line, which can cover the pens in the horizontal direction. With the movement of the vehicle body 1, it can cover the pens in the vertical direction, thereby realizing wide-area operation without multiple back and forth movements, thereby improving operation efficiency.

[0050] During the movement, multiple distance measuring sensor devices 24 cooperate to detect the area to be sprayed on the front side. If there are infrastructure obstacles such as pillars, the data of the distance measuring sensor device 24 facing the pillar will be different from that of other distance measuring sensor devices 24. The distance measuring sensor device 24 feeds back the data to the control module, and the control module drives the motor 30 to operate and rotate in the opposite direction to reel in the pipe assembly. After the last distance measuring sensor device 24 completes the perception of the obstacle, it reels in a fixed length so that the rotorcraft device 9 misses the obstacle, and then stops reeling. After the vehicle body 1 drives the pipe assembly to move to the area where the obstacle is missed, the turntable 13 releases the pipe assembly again, making it in a stretched state, thereby achieving avoidance of the obstacle.

[0051] After the obstacle is offset, the rotorcraft device 9 starts to operate, driving the pipe assembly to deflect backward, spraying and disinfecting the area flush with the obstacle, fully covering the enclosure area. As the pipe assembly deflects, it eventually wraps around the obstacle, spraying and disinfecting the corners of the obstacle, thereby achieving full coverage of dead corners and further improving the disinfection efficiency.

[0052] After the disinfection is completed, the pump body 23 is closed, the motor 30 is reversed, and the turntable 13 is driven to reverse and the pipe assembly is wound. During the winding process, the sleeve 3 passes through the first ring body 18, and the guide groove 302 is engaged with the ball 20 again. The sleeve 3 rotates in the opposite direction by ninety degrees, so that the nozzle 4 faces forward. Finally, multiple sleeves 3 are wound on the turntable 13, and under the interference of the blocking rod 29, multiple sleeves 3 are wound in a single-layer spiral, so that each nozzle 4 on the turntable 13 faces forward and will not be blocked. Since the turntable 13 is stepped, through the air hole 27, the two groups of wound pipe assemblies form a complete circular surface. At this time, the pump body 23 and the fan device 28 are started, and the wound nozzles 4 spray disinfectant, which is finally sucked and discharged by the fan device 28, thereby realizing horizontal directional spraying and disinfection to meet the operation needs of small areas, making the equipment more practical.

[0053] After the pipeline assembly is released, the sleeve 3 located between the first ring body 18 and the turntable 13 will not rotate, and the nozzle 4 thereon will be in a horizontally advanced state. At this time, the fan device 28 is running, and during the movement, it sprays and disinfects the walkway where the vehicle body 1 moves.

[0054] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
