Description

Technical Field

[0001] The invention relates to the technical field of orchard plant protection, and in particular to a contour-profiling rotary spraying device for orchards. Background Art

[0002] The existing orchard spraying device is fixed on a mobile vehicle when in use. The vehicle moves between the fruit trees and sprays the medicine on the fruit trees on both sides with the nozzles on the device in a large range. As the vehicle moves, the spraying device continues to operate and sprays the fruit trees indiscriminately. When the spraying of the fruit trees on both sides is completed, the vehicle moves to the next row of fruit trees and sprays the next row of fruit trees.

[0003] There are two disadvantages to this spray method:

[0004] On the one hand, during the operation of the existing spray device, due to the lush branches and leaves of some fruit trees, the penetration during the spraying process is limited, so the inside of the fruit trees cannot be effectively sprayed during the spraying, resulting in incomplete plant protection work and hidden dangers;

[0005] On the other hand, the spraying process is carried out indiscriminately without any protective measures, so it causes greater damage to the surrounding seedlings. Summary of the Invention

[0006] The purpose of the present invention is to provide a contour-profiling rotary spraying device for an orchard in order to solve the problems of incomplete spraying and damage to new seedlings during the spraying process of fruit trees.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

A spray mechanism is provided at the end of the adjustment mechanism, wherein the spray mechanism is used for spraying, and a water guide pipe is provided inside the spray mechanism.

[0009] The support mechanism includes a rectangular bracket, an I-shaped guide rail is fixed to the bottom of the rectangular bracket in the middle of the length direction, and two limit guide rails are fixed to the top of the rectangular bracket in the middle of the length direction. The I-shaped guide rail and the limit guide rail are used as the movement track of the upper device;

[0010] The adjusting mechanism includes two telescopic rods, the telescopic rod is located between the two limiting guide rails, the bottom end of the telescopic rod is fixed with a first walking wheel, the first walking wheel is rollingly connected to the top surface of the I-shaped guide rail, a first electric push rod is fixed to one side of the telescopic rod, a telescopic plate is fixed to the top of the telescopic rod, the two telescopic plates are symmetrically arranged along the length direction of the rectangular bracket, a second electric push rod is fixed to the top surface of the telescopic plate, one end of the telescopic plate is rotatably connected to a supporting frame, before starting to spray, the first electric push rod fixed on one side of the telescopic rod is started by the set telescopic rod to adjust the height of the spray, the first walking wheel is rolled on the top surface of the I-shaped guide rail so that the device can move to control the distance of the spray, the second electric push rod fixed on the telescopic plate is started by the set telescopic plate to adjust the distance of the spray, and the supporting frame is used to fix the lower device.

[0011] Furthermore, a rotating mechanism is provided on the bottom surface of the supporting frame, and the spray mechanism is provided on the bottom surface of the rotating mechanism. The bottom surface of the rotating mechanism is rotatably connected to two first shells, one end of the first shell is rotatably connected to the second shell, and one end of the second shell is rotatably connected to the third shell. Spray heads are fixed on both side surfaces of the first shell, the second shell and the third shell along the long side direction, and the connection between the first shell and the second shell, and the second shell and the third shell is rotatably connected to a third electric push rod. The rotating mechanism is fixed by the supporting frame. Before spraying starts, since the first shell is rotatably connected to the rotating mechanism, the angle of the first shell is adjusted, and then the deflection angles of the second shell and the third shell are adjusted by the third electric push rod to imitate the fruit tree.

[0012] Furthermore, a limit block is provided at the outer side of the telescopic rod corresponding to the position of the limit guide rail, a sleeve is fixed at the middle position of the limit block, and the sleeve is fixedly sleeved on the outer side of the telescopic rod, and two second motors are symmetrically fixed on the top of the limit block along the outer side of the length direction of the limit guide rail, and both ends of the top inner side of the limit block are rotatably connected to two second walking wheels, the motor shaft of the second motor passes through the limit block and is fixedly connected to the center position of the second walking wheel, and both ends of the bottom inner side of the limit block are rotatably connected to driven wheels, and the second walking wheel and the driven wheel are both rollingly connected to the limit guide rail, and the limit block and sleeve are used to fix the telescopic rod structure, and by starting the set second motor, the second walking wheel rolls on the limit guide rail, thereby driving the telescopic rod to move, and the set driven wheel rolls on the limit guide rail to make the telescopic rod more stable.

[0013] The transmission gear of the present invention is a gear which is connected with the gear of the driven gear to the external gear of the driven gear, and the gear is connected with the gear of the driven gear to the external gear of the driven gear. The rotatable connection is provided with a pawl movably engaged with the ratchet, and a compression spring is fixed between one side of the pawl and the rotating disk, and the ratchet is fixedly connected to the first shell. Before the spraying starts, since the ratchet and the first shell are fixedly connected, the angle of the first shell and the ratchet is manually adjusted to make the first shell imitate the fruit tree, and then the angle is fixed by the set pawl. After the spraying work starts, the first shell is used to support the internal structure, and the third motor fixed on the top surface of the motor seat is started to drive the first gear below to rotate, and the second gear meshing with the first gear also rotates, and the third gear on the other side is meshed with a second gear, so the third gear also rotates, so that the two rotating disks below rotate in opposite directions, driving the ratchet and the first shell below to rotate. Under the rotation of the first shell, the second shell and the third shell below are driven to rotate together, thereby realizing circumferential and all-round spraying of the fruit trees.

[0014] Furthermore, two sliding blocks are slidably connected to the inner side of one end of the first shell near the ratchet wheel. The two sliding blocks are staggered and arranged in opposite directions. The two sliding blocks are respectively located on both sides of the water pipe. Two return springs are fixed to one side of the sliding block. One end of the return spring is fixedly connected to the inner side wall of the first shell. A push rod is fixed to the other side of the sliding block. The push rod passes through the side wall of the first shell, and one end of the push rod is fixed to the push block. When a round of spraying is completed, the first shells on both sides approach each other, and the push blocks arranged on the two first shells contact and squeeze each other. Under the action of the push rod, a sliding block inside the first shell will slide toward the side wall of the first shell. When the two first shells are rotated to a parallel and side-by-side state, the sliding block is close to the side wall of the first shell. At this time, the water pipe arranged in the middle of the first shell will be squeezed by the sliding block to a water-cut-off state. When the next round of spraying is carried out, the first shells on both sides are separated. The sliding block will gradually slide toward the other side wall of the first shell through the return spring. At this time, the water pipe resumes normal water supply and continues to spray the fruit trees.

[0015] Furthermore, two arc-shaped telescopic rods are fixed at both ends of the inner sides of the first shell, the second shell and the third shell, and a shielding cloth is arranged between the two arc-shaped telescopic rods on the same side along the long side direction of the first shell, and the shielding cloth is fixedly connected to the arc-shaped telescopic rod end to end, and a bar magnet is fixed to the outside of one end of the shielding cloth. During spraying operation, when the two first shells are merged to one side, the shielding cloth and the arc-shaped telescopic rod inside the two first shells will be driven and adsorbed together by the provided bar magnet, and the provided first shell, the second shell and the third shell will rotate to drive the shielding cloth to unfold and block the spray. When the two first shells rotate to a certain angle and the distance exceeds the length of the shielding cloth, the provided bar magnets will separate, thereby realizing the shielding and recovery of the spray.

[0016] Furthermore, the first shell, the second shell and the third shell are provided with strip outlets at positions corresponding to the shielding cloth on both sides along the short side direction, and the arc-shaped telescopic rod and the shielding cloth can pass through the provided strip outlets.

[0017] Furthermore, the telescopic plate is a telescopic rod-like structure, the fixed end of the second electric push rod is fixedly connected to one end of the telescopic plate, and the output end of the second electric push rod is fixedly connected to the other end of the telescopic plate. Through the connection between the second electric push rod and the telescopic plate, the telescopic plate can be extended to control the distance of the spray.

[0018] Furthermore, one end of the inner wall of the arc-shaped telescopic rod is rotatably connected to a winding rod, a traction rope is wound around the outside of the winding rod, and one end of the traction rope is fixed to the inner wall of the output end of the arc-shaped telescopic rod. During the spraying process, when the first shell continues to separate and the shielding cloth reaches the maximum extension length, the bar magnet will separate. At this time, the winding rod arranged inside the arc-shaped telescopic rod starts to work to recycle the traction rope. Under the friction force of the arc-shaped telescopic rod itself, the winding rod will run slowly to gradually recycle the arc-shaped telescopic rod.

[0019] Furthermore, a first motor is fixed on the inner side of one end of the telescopic plate, and a motor shaft of the first motor passes through the side wall of the telescopic plate. A connecting rod is fixedly sleeved on the outer side of one end of the motor shaft, and one end of the connecting rod is fixedly connected to the supporting frame. When a round of spraying is completed, the first shells on both sides rotate to the other side and are close to each other, and then the first motor is started to drive the connecting rod to rotate, and the supporting frame fixed at the end of the connecting rod follows the rotation, thereby driving the rotating mechanism and the spray mechanism below to rotate, so that the first shell rotates to the initial position and stops, so as to facilitate the next round of spraying.

[0020] Beneficial effects of the present invention:

[0021] 1. Through the provided rotating mechanism, after the spraying starts, the provided third motor is started, which drives the first gear, the second gear and the third gear provided below to rotate, so that the two rotating disks below rotate in opposite directions, driving the ratchet wheel and the first shell below to rotate. Under the action of the rotation of the first shell, the second shell and the third shell below are driven to rotate together. At this time, the provided nozzle starts spraying, and the first shell, the second shell and the third shell on both sides rotate 180 degrees in two directions respectively to spray, thereby achieving all-round spraying of the circumference and the inner side of the fruit tree, thereby improving the quality of the fruit tree spraying;

[0022] 2. Through the provided arc-shaped telescopic rod and shielding cloth, when the spraying operation is carried out, when the two first shells are merged to one side, the provided bar magnet will drive the shielding cloth and the arc-shaped telescopic rod inside the two first shells to be adsorbed together. At this time, under the rotation of the rotating mechanism, the provided first shell, the second shell and the third shell rotate, driving the shielding cloth to unfold and shield the spray. When the two first shells rotate to a certain angle and the distance exceeds the length of the shielding cloth, the provided bar magnet separates, and the provided winding rod pulls the arc-shaped telescopic rod. At this time, the shielding cloths on both sides are slowly retracted while continuing to shield. When a round of spraying is completed, the shielding cloth is completely retracted, thereby achieving shielding of the spray and preventing the sprayed medicine from damaging the new seedlings.

[0023] 3. Through the provided pushing block and sliding block, when a round of spraying is completed, the first shells on both sides approach each other. At this time, the pushing blocks provided on the two first shells contact and squeeze each other, and a sliding block inside the first shell will slide toward the side wall of the first shell, compressing the provided return spring until the sliding block is close to the side wall of the first shell. At this time, the water pipe provided in the middle of the first shell will be squeezed to the side wall of the first shell by the sliding block until the water is cut off. When the next round of spraying is carried out, the first shells on both sides are separated. Under the action of the provided return spring, the sliding block gradually slides toward the other side wall of the first shell, loosening the water pipe to resume normal water supply, and continuing to spray the fruit trees, thereby achieving effective control of the spray and avoiding waste caused by unnecessary spraying and damage to other seedlings;

[0024] 4. By setting a third electric push rod, before the spraying starts, the third electric push rod is started. Since the second shell and the third shell are both rotatably connected, the second shell and the third shell will deflect until they are deflected to a suitable angle to perform profiling on the fruit tree. When a round of spraying is completed, the first motor is started to drive the carrier to rotate, thereby driving the rotating mechanism and the spray mechanism below to rotate, so that the first shell rotates to the initial position and then stops, and then the third electric push rod is started to deflect the first shell, the second shell and the third shell back to the initial angle for a new round of spraying, so that the device can work reciprocatingly through the rotating mechanism, thereby improving the spraying efficiency and avoiding waste of spray.

DETAILED DESCRIPTION

[0034] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] See also Figure 1-7As shown, a contoured rotary spray device for an orchard includes a support mechanism 100 and an adjustment mechanism 200.

The spray mechanism 400 is used for spraying. A water guide pipe 500 is provided inside the spray mechanism 400. The spray mechanism 400 is provided on the bottom surface of the rotating mechanism 300. The bottom surface of the rotating mechanism 300 is rotatably connected to two first shells 410. One end of the first shell 410 is rotatably connected to the second shell 420. One end of the second shell 420 is rotatably connected to the third shell 430. The first shell A nozzle 470 is fixed to both sides of the first shell 410, the second shell 420, and the third shell 430 along the longitudinal direction. A third electric push rod 411 is rotatably connected to the connection between the first shell 410 and the second shell 420, and the second shell 420 and the third shell 430. The rotating mechanism 300 is fixed by the supporting frame 260. Before spraying begins, the first shell 410 is rotatably connected to the rotating mechanism 300. By adjusting the angle of the first shell 410, the deflection angles of the second shell 420 and the third shell 430 are adjusted by the third electric push rod 411, so that the fruit tree is profiled.

[0036] The first shell 410 is connected to the inner side of one end of the ratchet 371 by sliding with two sliding blocks 440. The two sliding blocks 440 are staggered and arranged in opposite directions. The two sliding blocks 440 are respectively located on both sides of the water pipe 500. Two return springs 441 are fixed on one side of the sliding block 440. One end of the return spring 441 is fixedly connected to the inner side wall of the first shell 410. A push rod 442 is fixed on the other side of the sliding block 440. The push rod 442 passes through the side wall of the first shell 410, and a push block 460 is fixed on one end of the push rod 442. When a round of spraying is completed, the first shells 410 on both sides are close to each other. By setting the two first shells 410 The push blocks 460 on the first shell 410 contact and squeeze each other. Under the action of the push rod 442, a sliding block 440 inside the first shell 410 will slide toward the side wall of the first shell 410. When the two first shells 410 are rotated to a parallel and side-by-side state, the sliding block 440 is close to the side wall of the first shell 410. At this time, the water pipe set in the middle of the first shell 410 will be squeezed by the sliding block 440 to a water-cut state. When the next round of spraying is carried out, the first shells 410 on both sides are separated. The sliding block 440 will gradually slide toward the other side wall of the first shell 410 through the reset spring 441. At this time, the water pipe resumes normal water supply and continues to spray the fruit trees.

The shielding cloth 451 is fixedly connected to the arc-shaped telescopic rod 450 end to end, and a bar magnet 452 is fixed to the outside of one end of the shielding cloth 451. When the two first shells 410 are merged to one side, the bar magnet 452 will drive the shielding cloth 451 and the arc-shaped telescopic rod 450 inside the two first shells 410 to be adsorbed together, and the first shell 410, the second shell 420 and the third shell 430 are rotated to drive the shielding cloth 451 to unfold to block the spray. After the two first shells 410 rotate to a certain angle and the distance exceeds the length of the shielding cloth 451, the bar magnets 452 are separated, thereby realizing the shielding and recovery of the spray. The first shell 410, the second shell 420 and the third shell 430 are provided with bar outlets at the positions of the shielding cloth 451 on both sides along the short side direction. The arc-shaped telescopic rod 450 and the shielding cloth 451 can pass through the provided bar outlets smoothly. The support mechanism 100 includes a rectangular bracket 110.

The fixed end of the second electric push rod 240 is fixedly connected to one end of the telescopic plate 220, and the output end of the second electric push rod 240 is fixedly connected to the other end of the telescopic plate 220. Through the connection between the second electric push rod 240 and the telescopic plate 220, the telescopic plate 220 can be extended to control the distance of the spray.

[0039] Specifically, a limit block 250 is provided at the position of the limit guide rail 130 on the outside of the telescopic rod 210, and a sleeve 251 is fixed at the middle position of the limit block 250. The sleeve 251 is fixedly sleeved on the outside of the telescopic rod 210. Two second motors 252 are symmetrically fixed on the outside along the length direction of the limit guide rail 130.

The center position is set, and both ends of the inner side of the bottom of the limit block 250 are rotatably connected to the driven wheels 254. The second walking wheel 253 and the driven wheel 254 are both rollingly connected to the limiting guide rail 130. The limit block 250 and the sleeve 251 are set to fix the telescopic rod 210 structure. By starting the set second motor 252, the second walking wheel 253 rolls on the limiting guide rail 130, thereby driving the telescopic rod 210 to move. The set driven wheel 254 rolls on the limiting guide rail 130, making the telescopic rod 210 more stable.

[0040] Specifically, the rotating mechanism 300 includes a fixed housing 310, which is fixedly sleeved on the outside of the carrier 260. A motor base 320 is fixed to the inner bottom surface of the fixed housing 310. A third motor 321 is fixed to the top surface of the motor base 320. The motor shaft of the third motor 321 passes through the top of the motor base 320. A fixed disk 330 is fixed to the outside of one end of the motor shaft. A first gear 340 is fixed to the bottom surface of the fixed disk 330. Two second gears 350 are meshed on the outside of the first gear 340, and a third gear is meshed on the outside of the second gear 350. 360, the first gear 340, the second gear 350 and the third gear 360 are arranged side by side, and both ends of the outer bottom surface of the fixed housing 310 are rotatably connected to a rotating disk 370, and a rotating shaft is fixed to the center of the top surface of the rotating disk 370. The rotating shaft of one rotating disk 370 is fixedly connected to the center position of the third gear 360, and the rotating shaft of the other rotating disk 370 is fixedly connected to the center position of the other second gear 350. The bottom of the rotating disk 370 is rotatably connected to a ratchet 371, and the inner bottom surface of the rotating disk 370 is rotatably connected to a movable engaging member with the ratchet 371. The pawl 372 is provided, and a compression spring is fixed between one side of the pawl 372 and the rotating disk 370. The ratchet 371 is fixedly connected to the first housing 410. Before the spraying starts, since the ratchet 371 is fixedly connected to the first housing 410, the angle of the first housing 410 and the ratchet 371 is manually adjusted to make the first housing 410 contour the fruit tree. Then, the angle is fixed by the provided pawl 372. After the spraying starts, the first housing 410 is provided to support the internal structure and the third motor fixed on the top surface of the motor base 320 is activated. The machine 321 drives the first gear 340 below to rotate, and the second gear 350 engaged with the first gear 340 also rotates accordingly, while the third gear 360 on the other side engages with one of the second gears 350, so the third gear 360 also rotates accordingly, so that the two rotating disks 370 below rotate in opposite directions, driving the ratchet 371 below and the first shell 410 to rotate. Under the rotation of the first shell 410, the second shell 420 and the third shell 430 below are driven to rotate together, thereby realizing circumferential and all-round spraying of the fruit trees.

[0041] Specifically, one end of the inner wall of the arc-shaped telescopic rod 450 is rotatably connected to a winding rod 453, and a traction rope is wound around the outside of the winding rod 453. One end of the traction rope is fixed to the other end of the inner wall of the arc-shaped telescopic rod 450. During the spraying process, when the first shell 410 continues to separate and the shielding cloth 451 reaches the maximum extension length, the bar magnet 452 will separate. At this time, the winding rod 453 set inside the arc-shaped telescopic rod 450 starts to work and recycles the set traction rope. Under the friction force of the arc-shaped telescopic rod 450 itself, the winding rod 453 will run slowly and gradually recycle the arc-shaped telescopic rod 450. One end of the telescopic plate 220 is inside A first motor 221 is fixed on the side, and the motor shaft of the first motor 221 passes through the side wall of the telescopic plate 220. A connecting rod 222 is fixedly sleeved on the outside of one end of the motor shaft. One end of the connecting rod 222 is fixedly connected to the supporting frame 260. When a round of spraying is completed, the first shells 410 on both sides rotate to the other side and are close to each other, and then the first motor 221 is started to drive the connecting rod 222 to rotate, and the supporting frame 260 fixed at the end of the connecting rod 222 follows the rotation, thereby driving the rotating mechanism 300 and the spray mechanism 400 below to rotate, so that the first shell 410 rotates to the initial position and stops to facilitate the next round of spraying.

[0042] Working principle: When in use, fix the rectangular bracket 110 to the top surface of the mobile vehicle's bucket, adjust the first electric push rod 230 and the second electric push rod 240 to extend the telescopic rod 210 and the telescopic plate 220 to a suitable length, adjust the ratchet 371 to control the angle of the first shell 410, and control the deflection angle of the second shell 420 and the third shell 430 through the third electric push rod 411, so that the spray mechanism 400 device can imitate the fruit tree and get as close to the outer edge of the fruit tree as possible. The vehicle is then started and driven along the rows of fruit trees. Water pipes are provided on the inner sides of the first housing 410, the second housing 420, and the third housing 430. The water pipes are connected to the corresponding nozzles 470. The water pipes are connected to a water tank, which supplies water to the water pipes. The water is pumped into the water pipes and then sprayed out from the nozzles 470. When the spray mechanism 400 approaches the fruit trees, the first housing 410, the second housing 420, and the third housing 430 at both ends are respectively attached to the fruit trees on both sides of the row, and then the spraying operation is carried out.

[0043] After spraying begins, the third motor 321 is started, which drives the first gear 340 below to rotate, and the second gear 350 meshing with the first gear 340 also rotates accordingly, while the third gear 360 on the other side meshes with one of the second gears 350, so the third gear 360 also rotates accordingly, so that the two rotating disks 370 below rotate in opposite directions, driving the ratchet 371 below and the first housing 410 to rotate. Under the action of the rotation of the first housing 410, the second housing 420 and the third housing 430 below rotate together. At this time, the spray head 470 is spraying, and the first housings 410 on both sides respectively rotate 180 degrees to spray, thereby achieving circumferential and all-round spraying of the fruit trees.

[0044] When a round of spraying is finished, the first shells 410 on both sides are close to each other. At this time, the pushing blocks 460 provided on the two first shells 410 contact and squeeze each other. Under the action of the pushing rod 442, a sliding block 440 inside the first shell 410 will slide toward the side wall of the first shell 410. When the first shells 410 on both sides finish rotating, the sliding block 440 is pushed by the pushing block 460 and the pushing rod 442, and the sliding block 440 is close to the side wall of the first shell 410. At this time, the water pipe provided in the middle of the first shell 410 will be squeezed to the side wall of the first shell 410 by the sliding block 440 until the water is cut off. When the next round of spraying is carried out, the first shells 410 on both sides are separated. The sliding block 440 gradually slides toward the other side wall of the first shell 410 under the action of the reset spring 441. At this time, the water pipe resumes normal water supply and continues to spray the fruit trees.

[0045] At the beginning of the spraying, the first shells 410 on both sides are in a close state. At this time, the bar magnets 452 arranged on the adjacent surfaces of the two adjacent shielding cloths 451 attract each other and fit together. At this time, the shielding cloths 451 on both sides are unfolded to form a shield. The arc-shaped telescopic rods 450 arranged inside the first shell 410, the second shell 420 and the third shell 430 are driven by the shielding cloths 451 to get close to each other and fit together. When the first shell 410 continues to separate, the shielding cloth 451 continues to unfold, driving the arc-shaped telescopic rods 450 to continue to extend, the winding rod 453 releases the traction rope, and the clockwork spring is deformed. However, at this time, the two bar magnets 452 that fit together do not separate, and the spray is effectively shielded. , to avoid damage to the seedlings by the spray, when the shielding cloth 451 reaches the maximum extension length, the bar magnet 452 will separate. At this time, the clockwork spring recovers its deformation, thereby driving the winding rod 453 set inside the arc-shaped telescopic rod 450 to start working and retract the set traction rope. Under the friction of the arc-shaped telescopic rod 450 itself, the winding rod 453 will run slowly and gradually retract the arc-shaped telescopic rod 450. At this time, the shielding cloth 451 continues to block until it is completely retracted, and then the first shells 410 on both sides rotate to the other side and are close to each other. At this time, the bar magnets 452 on the other side attract each other and fit together, driving the shielding cloth 451 on the other side to unfold;

[0046] When a round of spraying is completed, the first shells 410 on both sides rotate to the other side and are close to each other, and then the first motor 221 is started to drive the connecting rod 222 to rotate, and the carrier 260 fixed at the end of the connecting rod 222 rotates, thereby driving the rotating mechanism 300 and the spray mechanism 400 below to rotate, so that the first shell 410 rotates to the initial position and stops, and then the third electric push rod 411 is started to deflect the first shell 410, the second shell 420 and the third shell 430 back to the initial angle, and start the next round of spraying.
