Description

Technical Field

[0001] The present invention relates to the technical field of agricultural planting and fertilization, and in particular to a power mechanical equipment for agricultural rice planting. Background Art

[0002] Drone fertilization is currently a commonly used fertilization method for large-scale rice planting. As a power machinery in agricultural rice planting, it can effectively improve the efficiency of planting and fertilization, accurately fertilize rice, and improve farmland management efficiency and rice productivity.

[0003] The existing spraying UAV has a single structure of the spray head and poor applicability. Generally, one spray head can only be applied to one type of crop, and the spray coverage cannot be adjusted according to needs. In addition, due to factors such as wind resistance in the air and airflow blowing during the flight of the UAV, the publication number CN115158646B discloses a self-adjusting spraying device for UAV fertilization, which includes a liquid medicine tank and a spraying device arranged on the UAV body; the spraying device includes a spray head, a spray head adjustment assembly and a storage drive mechanism; the spray head adjustment assembly includes a top plate, a sealing plate, a connecting rod mechanism arranged between the top plate and the sealing plate, and a linear drive mechanism; the sealing plate cooperates with the bottom of the storage cabin; the storage drive mechanism is arranged in the storage cabin, and is used to drive the sealing plate to do lifting and lowering movements; the linear drive mechanism is used to drive the top plate to do vertical movement to drive the connecting rod mechanism to expand or retract; the connecting rod mechanism includes a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod and a fifth connecting rod.

[0004] The above-mentioned self-adjusting spraying device controls the nozzle adjustment component according to the different flight altitudes or different inclination angles of the drone, so as to change the spray angle and spray range of the nozzle. At the same time, the spraying range can also be selected according to different types of plants, so that the drone is not easily affected by wind resistance and airflow during the spraying process. The spraying range can be accurately sprayed on the surface of crops, avoiding waste of liquid medicine and reducing cost consumption.

[0005] However, when the above-mentioned self-adjusting spraying device is used in practice, due to the change in the angle of the nozzle, the pump will cause a part of the liquid kinetic energy to be lost when transporting the liquid medicine to the nozzle. It is necessary to change the operating power of the pump to offset the energy loss after the nozzle angle is changed. This requires precise control of the power adjustment accuracy of the pump. At present, there is no high-precision pump that can fine-tune the power. In addition, the mist of the liquid medicine sprayed from the nozzle is greatly affected by the wind. Even if the angle of the nozzle is changed, the spray of the mist cannot accurately fall on the rice, affecting the uniformity of the medicine.

[0006] Therefore, a new type of agricultural rice planting power machinery equipment can be adopted to solve the shortcomings of the prior art. Summary of the invention

[0007] The purpose of the present invention is to solve the problems in the prior art that the output efficiency of the nozzle is reduced due to the change of the nozzle angle and the spraying is uneven due to the influence of wind, and to propose a power mechanical equipment for agricultural rice planting.

[0014] Preferably, the limiting structure comprises a plurality of sliding tracks fixedly mounted inside the connecting pipe, and a plurality of limiting sliding plates matched with the corresponding sliding tracks are fixedly mounted on the connecting pipe.

[0015] Preferably, the water baffle is fixedly connected to the nozzle via a hollow frame, and the end of the water baffle close to the high-pressure nozzle is of conical design, and the tip of the cone is located on the same vertical line as the central axis of the high-pressure nozzle.

[0016] Preferably, the adjustment mechanism includes a first motor fixedly mounted on the outer tube, a toothed disc fixedly mounted on the driving end of the first motor, a fixing ring fixedly mounted on the adjusting threaded sleeve, and an inner toothed ring meshing with the toothed disc fixedly mounted on the fixing ring.

[0017] Preferably, the steering and boosting mechanism consists of a steering structure, a boosting structure and a telescopic liquid outlet pipe, the steering structure is used to change the direction of the telescopic liquid outlet pipe to offset wind force, and the boosting structure is used to change the spraying speed of the liquid in the telescopic liquid outlet pipe.

[0018] Preferably, the steering structure comprises a tapered pipe fixedly mounted on the outer pipe, the tapered pipe is fixedly connected to the telescopic liquid outlet pipe, a first adjustment frame is rotatably mounted on the tapered pipe, two first electric push rods are rotatably mounted on the tapered pipe, and the telescopic ends of the two first electric push rods are rotatably connected to the first adjustment frame;

[0019] A second adjusting frame is rotatably mounted on the first adjusting frame, the second adjusting frame is fixedly connected to the telescopic liquid outlet pipe, a second electric push rod is rotatably mounted on the first adjusting frame, and the telescopic end of the second electric push rod is rotatably connected to the second adjusting frame.

[0020] Preferably, the boost structure includes a shaft rotatably mounted on an outer tube, a first turbofan rotatably mounted on the shaft, the first turbofan and the outer tube are fixedly connected, and a second turbofan is fixedly mounted on the shaft, the first turbofan and the second turbofan are rotatably connected, and a driving component matching the shaft is mounted on the outer tube.

[0021] Preferably, the driving component includes a sleeve fixedly mounted on the outer tube, a connecting shaft is rotatably mounted on the sleeve, the connecting shaft passes through and extends into the interior of the outer tube, the connecting shaft and the shaft body are connected via a first bevel gear set, a second motor is fixedly mounted on the outer tube, and the driving end of the second motor is connected to the connecting shaft via a second bevel gear set.

[0022] Preferably, the first turbofan and the second turbofan have opposite rotation directions, and both the first turbofan and the second turbofan are conical in shape, and the two conical shapes are in opposite directions.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] 1. When the device is used for spraying pesticides for rice planting, the direction of the telescopic liquid outlet pipe is adjusted by setting a steering structure, so that the liquid outlet of the telescopic liquid outlet pipe is opposite to the wind direction, and the direction of the sprayed pesticide is opposite to the wind direction, which is used to eliminate the influence of wind force, and can effectively and accurately spray the pesticide on the rice, and the spraying is more uniform.

[0025] 2. When the device is spraying pesticides for rice planting, the adjustment mechanism is set to change the distance between the high-pressure nozzle and the baffle, thereby changing the storage space of the pesticide inside the casing, so that the pesticide mist sprayed by the high-pressure nozzle is in contact with the inner wall of the casing for a longer time, thereby changing the size of the condensed particles of the pesticide mist in the casing, which is used to adapt to wind forces of different sizes. The stronger the wind force, the larger the condensed particles, the larger the particles, the heavier the weight of the particles, and the less affected by the wind force, and the spraying amount of the pesticide remains unchanged. While ensuring the spraying amount, the influence of wind force on the spraying direction of the pesticide is further reduced, making the pesticide spraying more uniform and accurate.

[0026] 3. When the device is spraying pesticides for rice planting, the first turbofan is set to further condense the pesticide particles and further increase the size of the pesticide particles. The second turbofan is used to accelerate the pesticide particles and speed up the spraying speed of the pesticide particles. The rotation speed of the second turbofan changes with the wind force to avoid the increase of pesticide particles and the failure to achieve the best spraying effect. At the same time, it can also eliminate the situation where the spraying force is reduced due to the steering of the telescopic liquid outlet pipe, ensuring that the spraying range of the pesticide is within the optimal spraying range.

[0027] In summary, when spraying pesticides for rice planting, the present invention offsets the influence of wind through a telescopic liquid outlet tube that can change direction. At the same time, the size of the sprayed pesticide particles and the spraying speed of the pesticide particles can be adjusted according to the wind force, ensuring that the spraying amount and spraying range of the pesticide are within the optimal range, making the pesticide spraying more uniform and accurate.

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0046] Example 1: Reference Figure 1-Figure 2 , a power mechanical equipment for agricultural rice planting, including a flight unit and a spraying unit fixedly installed on the flight unit; the flight unit is an existing common aircraft, and its specific driving, steering and hovering are not elaborated here.

[0047] The flight unit drives the spraying unit to spray medicine in the air. The flight unit includes an aircraft frame 1, on which a plurality of aircraft wings 2 are rotatably mounted. A control panel 4 matched with the aircraft wings 2 is fixedly mounted on the aircraft frame 1 for controlling the aircraft wings 2.

[0048] The aircraft wing 2 can change direction freely, and the control panel 4 includes speed control and direction control for the aircraft wing 2. At the same time, wind direction and wind force sensors are installed in the control panel 4 to sense wind direction and wind force, and adjust the operating state of the aircraft wing 2 through the controller. The control panel 4 can also control the spraying speed, spraying direction and spraying particle size according to the wind direction and wind force.

[0049] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 2-Figure 15 The spraying unit includes a medicine box 5 fixedly mounted on the aircraft frame 1, and a spraying assembly 3 is fixedly mounted on each aircraft wing 2, and the medicine box 5 is connected to each spraying assembly 3 through an infusion tube 6;

[0050] The medicine box 5 is equipped with a pump and a mixing unit, and the pump delivers the pesticide liquid in the medicine box 5 to the spraying component 3 through the infusion pipe 6, and then sprays it out through the spraying component 3;

[0051] The stirring unit is a common stirring and mixing structure, which can regularly stir the pesticide liquid in the medicine box 5 to reduce the probability of precipitation of some substances in the pesticide liquid and ensure the activity of the pesticide liquid.

[0052] The spraying assembly 3 comprises a connecting pipe 8 fixedly mounted on the aircraft wing 2 , on which an adjusting threaded sleeve 18 is rotatably mounted, and on which a spraying mechanism 12 cooperating with the infusion tube 6 is mounted.

[0053] refer to Figure 5-Figure 11The spraying mechanism 12 includes a sleeve 13 fixedly installed inside the outer tube 7, the sleeve 13 is rotatably connected to the adjusting threaded sleeve 18, a nozzle 14 is fixedly installed at one end of the sleeve 13, a water baffle 21 is fixedly installed inside the nozzle 14, a high-pressure nozzle 20 matched with the nozzle 14 is slidably installed in the sleeve 13, an external threaded pipe 19 threadably rotatably connected to the adjusting threaded sleeve 18 is fixedly installed on the high-pressure nozzle 20, a connecting conduit 9 is fixedly installed on the external threaded pipe 19, the connecting conduit 9 is fixedly connected to the infusion tube 6, and a limiting structure is installed between the connecting conduit 9 and the connecting pipe 8.

[0054] The pesticide liquid in the medicine box 5 is transported to the connecting conduit 9 through the infusion tube 6 by a pump, and then enters the high-pressure nozzle 20 through the external threaded pipe 19. The pesticide liquid is atomized by the high-pressure nozzle 20, and the atomized pesticide liquid sprayed from the high-pressure nozzle 20 enters the sleeve 13, condenses in contact with the inner wall of the sleeve 13, making the mist particles larger, and then is sprayed out through the nozzle 14.

[0055] The function of the water baffle 21 is to block the atomized pesticide liquid to prevent the uncondensed pesticide liquid mist from being directly sprayed out from the nozzle 14 . Meanwhile, the atomized pesticide liquid can also condense on the water baffle 21 .

[0056] The limiting structure includes a plurality of sliding tracks fixedly installed inside the connecting tube 8, and a plurality of limiting sliding plates matching the corresponding sliding tracks are fixedly installed on the connecting conduit 9; the purpose of this part of the design is to limit the connecting conduit 9 to ensure that the connecting conduit 9 can only move inside the connecting tube 8 and cannot rotate.

[0057] The water baffle 21 is fixedly connected to the nozzle 14 by a hollow frame. The end of the water baffle 21 close to the high-pressure nozzle 20 is designed to be conical, and the tip of the cone is located on the same vertical line as the central axis of the high-pressure nozzle 20. The purpose of the shape design here is to guide the pesticide liquid particles so that the pesticide liquid particles spread around and avoid vertical reflection of the pesticide liquid particles, which can effectively increase the spraying kinetic energy of the pesticide liquid particles.

[0058] An outer tube 7 is rotatably mounted on the adjusting threaded sleeve 18, an adjusting mechanism 11 matching the adjusting threaded sleeve 18 is mounted on the outer tube 7, the adjusting mechanism 11 includes a first motor 17 fixedly mounted on the outer tube 7, a toothed disc is fixedly mounted on the driving end of the first motor 17, a fixing ring 15 is fixedly mounted on the adjusting threaded sleeve 18, and an inner toothed ring 16 meshing with the toothed disc is fixedly mounted on the fixing ring 15.

[0059] Stable wind direction and relatively low wind speed help to keep the spray of pesticides uniform and effective, ensuring that each part of the crop can receive an appropriate amount of pesticides. When the wind speed is too high, the spray particles will be unevenly distributed, resulting in insufficient coverage of the pesticides. At this time, the control panel 4 controls the operation of the first motor 17, and the wind force sensor senses the wind force, and then controls the speed of the first motor 17 through the controller;

[0060] The driving end of the first motor 17 rotates to drive the gear disk fixedly connected thereto to rotate, the gear disk rotates to drive the inner gear ring 16 meshing therewith to rotate, the inner gear ring 16 rotates to drive the fixed ring 15 fixedly connected thereto to rotate, the fixed ring 15 rotates to drive the adjusting threaded sleeve 18 fixedly connected thereto to rotate, the adjusting threaded sleeve 18 rotates to drive the external threaded pipe 19 threadably connected thereto to move, the external threaded pipe 19 rotates to drive the high-pressure nozzle 20 to move, thereby changing the distance between the high-pressure nozzle 20 and the nozzle 14, at which time the space between the high-pressure nozzle 20 and the nozzle 14 nozzle outlet increases, increasing the condensation area of ​​the pesticide liquid mist, and increasing the condensation particles of the pesticide liquid;

[0061] The stronger the wind, the larger the condensed particles. The larger the particles, the heavier the weight of the particles, and the less affected by the wind. The spraying amount of pesticides remains unchanged. While ensuring the spraying amount, the influence of wind on the spraying direction of pesticides is further reduced, making the pesticide spraying more uniform and accurate.

[0062] Since the pesticide liquid is in particle form and diffuses in the air, when the natural wind blows through the diffused pesticide liquid particle group, the particles that come into contact with the wind first are subjected to a greater force of the natural wind, while the pesticide liquid particles located at the back are subjected to a smaller wind force due to the obstruction of the pesticide liquid particles in front. Therefore, the wind force will blow the pesticide liquid particles located on the windward side to the middle of the pesticide liquid particle group. At this time, the pesticide liquid particle group will shrink, and some pesticide liquid particles will condense into larger particles or even condense into water droplets, thus affecting the uniformity of spraying. Increasing the weight of the pesticide liquid particles here can effectively reduce the probability of the pesticide liquid particles located on the windward side being blown by the wind, thereby reducing the probability of the pesticide liquid particle group located on the windward side shrinking, and ensuring that the coverage range of the pesticide liquid particle group is within the optimal spraying range.

[0063] Since the rotation of the driving end of the first motor 17 will drive the adjusting threaded sleeve 18 to rotate, and the adjusting threaded sleeve 18 is rotatably connected to the connecting tube 8 and the outer tube 7, the rotation of the adjusting threaded sleeve 18 will not be able to drive the outer tube 7 to rotate due to the action of friction. At this time, a connecting rod is installed between the outer tube 7 and the connecting tube 8 to fix the outer tube 7. At this time, the outer tube 7 will not rotate. Since this design is a common fixation, it is not shown in the figure. Once the outer tube 7 is fixed, the rotation of the driving end of the first motor 17 will only drive the adjusting threaded sleeve 18 to rotate.

[0064] A steering and boosting mechanism 10 is fixedly mounted on the outer tube 7; the steering and boosting mechanism 10 consists of a steering structure, a boosting structure and a telescopic liquid outlet pipe 29. The steering structure is used to change the direction of the telescopic liquid outlet pipe 29 to offset wind force, and the boosting structure is used to change the spraying speed of the liquid in the telescopic liquid outlet pipe 29.

[0065] refer to Figure 12-13 The steering structure includes a tapered pipe 26 fixedly mounted on the outer pipe 7, the tapered pipe 26 is fixedly connected to the telescopic liquid outlet pipe 29, a first adjustment frame 27 is rotatably mounted on the tapered pipe 26, two first electric push rods 30 are rotatably mounted on the tapered pipe 26, and the telescopic ends of the two first electric push rods 30 are rotatably connected to the first adjustment frame 27;

[0066] A second adjusting frame 31 is rotatably mounted on the first adjusting frame 27 , and the second adjusting frame 31 is fixedly connected to the telescopic liquid outlet pipe 29 . A second electric push rod 32 is rotatably mounted on the first adjusting frame 27 , and the telescopic end of the second electric push rod 32 is rotatably connected to the second adjusting frame 31 .

[0067] The pesticide liquid sprayed from the nozzle 14 will enter the tapered pipe 26. Due to the change in the inner diameter of the tapered pipe 26, the pesticide liquid will be pressurized, thereby accelerating the spraying speed of the pesticide liquid.

[0068] After the pesticide liquid enters the conical pipe 26, it will directly enter the telescopic liquid outlet pipe 29. At this time, the wind direction and wind force sensor is used to sense the wind direction and wind force, and then the controller controls the operation of the first electric push rod 30 and the second electric push rod 32. The two first electric push rods 30 will change the left and right directions of the first adjustment frame 27 (left and right here refer to Fig.13 ), the second electric push rod 32 will change the up and down direction of the second adjustment frame 31 (here up and down refer to Fig.13 ), so as to change the direction of the liquid outlet of the telescopic liquid outlet pipe 29 fixedly connected to the second adjustment frame 31, so that the direction of the liquid outlet is opposite to the wind direction, which is used to offset the influence of wind force on the spraying of pesticide liquid and make the spraying of pesticide liquid more uniform.

[0069] The boost structure includes a shaft body rotatably mounted on the outer tube 7, on which a first turbofan 28 is rotatably mounted, the first turbofan 28 and the outer tube 7 are fixedly connected, and a second turbofan 33 is fixedly mounted on the shaft body, the first turbofan 28 and the second turbofan 33 are rotatably connected, and a driving component matching the shaft body is mounted on the outer tube 7.

[0070] The pesticide liquid sprayed from the nozzle 14 passes through the first turbofan 28 and undergoes a second condensation on the surface of the first turbofan 28, further increasing the diameter of the condensed pesticide liquid particles.

[0071] The pesticide liquid particles after the second condensation by the first turbofan 28 enter the second turbofan 33. The rotation of the second turbofan 33 will throw out the condensed pesticide liquid particles, accelerate the movement speed of the pesticide liquid particles, and also produce a certain degree of rotation. The rotation can effectively increase the amount of medicine output. Due to the increase in the space between the high-pressure nozzle 20 and the nozzle 14, the pressure in the space will decrease, so the spraying speed of the pesticide liquid particles will decrease. Therefore, the second turbofan 33 performs an energy-enhancing operation on the pesticide liquid particles after the kinetic energy is reduced to ensure the spraying range of the pesticide liquid particles. At the same time, the rotation speed of the second turbofan 33 can be adjusted according to the change in the distance between the high-pressure nozzle 20 and the nozzle 14.

[0072] The driving component includes a sleeve fixedly mounted on the outer tube 7, on which a connecting shaft 23 is rotatably mounted, the connecting shaft 23 passes through and extends into the interior of the outer tube 7, the connecting shaft 23 is connected to the shaft body via a first bevel gear set 24, a second motor 22 is fixedly mounted on the outer tube 7, and a driving end of the second motor 22 is connected to the connecting shaft 23 via a second bevel gear set 25.

[0073] The second motor 22 drives the linkage shaft 23 to rotate through the second bevel gear set 25, and the linkage shaft 23 drives the shaft body to rotate through the first bevel gear set 24. The shaft body drives the second turbofan 33 fixedly connected thereto to rotate.

[0074] The purpose of this design is to place the second motor 22 outside the outer tube 7, which can effectively reduce the internal components of the outer tube 7, so that the pesticide liquid particles move more smoothly in the outer tube 7 and reduce the condensation of ineffective pesticide liquid particles;

[0075] The function of the sleeve is to support the linkage shaft 23, increase the force-bearing area of ​​the linkage shaft 23, and reduce the probability of bending and deformation of the linkage shaft 23. Balls are arranged in the sleeve to reduce the friction resistance encountered by the linkage shaft 23 during rotation, thereby ensuring the output power of the second motor 22.

[0076] The first turbofan 28 and the second turbofan 33 have opposite rotation directions, and both the first turbofan 28 and the second turbofan 33 are in a cone shape, and the two cone shapes are in opposite directions. The purpose of the cone shape design of the first turbofan 28 is to decompress the pesticide liquid particles, so that the pesticide liquid particles pass through the first turbofan 28 more slowly and the condensation effect is better. The purpose of the cone shape design of the second turbofan 33 is to pressurize the pesticide liquid particles and speed up the spraying speed of the pesticide liquid particles.

[0077] The specific operation steps of this device are as follows:

[0078] When strong winds suddenly occur during the spraying process, the wind force and wind direction sensors will sense the wind force and wind direction, and then control the first motor 17, the second motor 22, the first electric push rod 30 and the second electric push rod 32 to operate through the controller;

[0079] During spraying, the pump conveys the pesticide liquid in the medicine box 5 to the connecting conduit 9 through the infusion tube 6, and then enters the high-pressure nozzle 20 through the external threaded pipe 19, and the pesticide liquid is atomized by the high-pressure nozzle 20. The atomized pesticide liquid sprayed from the high-pressure nozzle 20 enters the sleeve 13, contacts the inner wall of the sleeve 13 in the sleeve 13, and performs the first condensation, so that the mist particles are larger (mist particle size adjustment: the first motor 17 driving end rotates to drive the gear disk fixedly connected thereto to rotate, and the gear disk rotates to drive the inner gear ring 16 meshing therewith to rotate, and the inner gear ring 16 meshing therewith rotates. The rotation of the gear ring 16 drives the fixed ring 15 fixedly connected thereto to rotate, the rotation of the fixed ring 15 drives the adjusting threaded sleeve 18 fixedly connected thereto to rotate, the rotation of the adjusting threaded sleeve 18 drives the external threaded pipe 19 threadedly connected thereto to move, the rotation of the external threaded pipe 19 drives the high-pressure nozzle 20 to move, thereby changing the distance between the high-pressure nozzle 20 and the nozzle 14. At this time, the space between the high-pressure nozzle 20 and the nozzle 14 is increased, the condensation area of ​​the pesticide liquid mist is increased, and the condensed particles of the pesticide liquid are increased, and vice versa, the particle size is reduced);

[0080] The pesticide liquid sprayed from the nozzle 14 will enter the tapered pipe 26, and the pesticide liquid in the tapered pipe 26 will pass through the first turbofan 28, and will be condensed for the second time on the surface of the first turbofan 28, further increasing the diameter of the condensed pesticide liquid particles;

[0081] The pesticide liquid particles after the second condensation by the first turbofan 28 enter the second turbofan 33. At this time, the second motor 22 is in operation. The rotation of the driving end of the second motor 22 drives the linkage shaft 23 to rotate through the second bevel gear set 25. The rotation of the linkage shaft 23 drives the shaft body to rotate through the first bevel gear set 24. The rotation of the shaft body drives the second turbofan 33 fixedly connected thereto to rotate. The rotation of the second turbofan 33 will throw out the condensed pesticide liquid particles, accelerate the movement speed of the pesticide liquid particles, and also produce a certain degree of rotation, which increases the output of the pesticide.

[0082] The pesticide liquid particles thrown out from the second turbofan 33 will enter the telescopic liquid outlet pipe 29. At this time, the wind direction and wind force are sensed by the wind direction and wind force sensor, and then the first electric push rod 30 and the second electric push rod 32 are controlled by the controller to operate. The two first electric push rods 30 will change the left and right direction of the first adjustment frame 27, and the second electric push rod 32 will change the up and down direction of the second adjustment frame 31, so as to change the direction of the liquid outlet of the telescopic liquid outlet pipe 29 fixedly connected to the second adjustment frame 31, so that the direction of the liquid outlet is opposite to the wind direction, which is used to offset the influence of wind force on the spraying of pesticide liquid and make the spraying of pesticide liquid more uniform.

[0083] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
