Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent spraying technology, and particularly relates to an intelligent sprayer for protected vegetables. Background Art

[0002] Our country is a large agricultural country, and pesticides are needed in agricultural production. However, most of them use traditional mechanical spraying or manual spraying. The unique closed and humid environment in greenhouses provides conditions for the occurrence and spread of pests and diseases. The pests and diseases of greenhouse crops are relatively serious, and there is a great demand for pesticides. Therefore, spraying operations need to be carried out frequently.

[0003] The Chinese invention patent with the authorization announcement number CN114097587B discloses a dual-purpose spraying device for field pest control and irrigation, including a main body mechanism and a secondary body mechanism. The secondary body mechanism is arranged at the upper end of the main body mechanism. When irrigation is required, the inner pipe is opened and the long pipe is closed. At this time, only the clear water in storage tank A flows out from the inner pipe to achieve the irrigation effect. On the contrary, when pest control is required, the inner pipe is closed and the long pipe is opened. At this time, only the liquid medicine in storage tank B flows out from the long pipe to achieve the pest control effect, so that the whole can achieve the irrigation effect and the spraying and pest control effect at the same time, with little influence between the two, and the work efficiency is improved. At the same time, during the use of the liquid medicine, the wooden board will continuously descend until the liquid level of the liquid medicine is lower than the magnetic column. The magnetic plate is attracted to the magnetic column, causing the wooden board to contact the magnetic column and make a sound to remind the staff that the liquid medicine is insufficient. However, in actual use, the spraying effect of the equipment on liquid fertilizers, liquid medicines, etc. is poor, the angle adjustment ability is weak, and the spraying accuracy is low.

One side of the turntable close to the nozzle is hinged to both sides of the outside of the nozzle through two opposed support blocks, and the tail of the nozzle is connected to the liquid delivery sac through a flexible pipeline passing through the stabilizing frame.

[0014] As a further description of the above technical solution:

[0015] One side of the turntable is connected to a rotating block. The rotating block is rotatably connected to an arc-shaped groove opened on the inner side of the stabilizing frame.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0023] 1. In the present invention, when a plurality of nozzles are arranged around the front side of the sprayer main body, the nozzles at the same horizontal position can be controlled by the pulling rods. When the first pushing portion works to extend or shorten and pull the slider to move, the movement of the slider can drive the moving block and the connecting rod to move. The movement of the connecting rod can drive the pulling rod on the other side to move. The movement of the pulling rod can drive the nozzle to deflect around the moving direction of the pulling rod. By adjusting the corresponding nozzles in the horizontal position, the spraying direction of the liquid can be changed. When the opening direction of the sprayer main body is fixed, by controlling the telescopic amount of the first pushing portion, the angle of the nozzle can be offset to change the spraying trajectory of the liquid, reducing the interference of environmental airflow, which is beneficial to the intelligent spraying of facility vegetables with different plant height differences, improving the control accuracy of the liquid supplement amount for the roots or leaves of vegetables, and realizing multiple functions such as pesticide application, application of water-soluble fertilizer or water supply.

[0024] 2. In the present invention, when the pulling rod pulls the nozzle to move, the nozzle can rotate around the hinge position of the support block to adapt to the angle adjustment of the spraying direction. And when the pulling rod further pulls, the turntable can rotate through the top rotating block in the arc groove. Thus, through the respective rotations of the turntable and the nozzle, the full adaptation to the angle offset can be improved, maintaining the controllability of the spraying angle. And through the designed adjusting spring and guiding rod, the turntable can rotate more stably through the external rotating block. And when the rotating block moves, it can squeeze the external adjusting spring. The adjusting spring can use its own elastic force to absorb the impact of the rotating block and reset the turntable. Thus, the rotating stability of the nozzle can be improved.

[0025] 3. In the present invention, through the designed guiding mechanism and closing mechanism, when the motor of the driving part drives the gear to drive the toothed ring to rotate, the rotation of the toothed ring can drive the inner shielding plate to move, and the movement of the shielding plate can open the gap of the bottom air inlet groove, so that the air inlet gap can be adjusted by closing the air inlet groove, facilitating the adjustment of the coverage range of the air-blast spray and improving the adaptability.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figures 1 - 11 , the present invention provides a technical solution: an intelligent sprayer for protected vegetables, including a vehicle body 1, a bracket 8 is provided on the top of the vehicle body 1, the main body 2 of the sprayer is rotatably connected inside the bracket 8, a direction control mechanism 6 is provided on the bottom side of the main body 2 of the sprayer, the direction control mechanism 6 is installed on the top of the vehicle body 1, the overall orientation of the main body 2 of the sprayer is controlled through the direction control mechanism 6, and a water tank 3 is provided on the top of the vehicle body 1. One side of the water tank 3 is connected to a pump body through a pipeline, and the pump body is communicated with the main body 2 of the sprayer. A control cabinet 9 is installed on one side of the vehicle body 1, and the pump body and the corresponding drive components are controlled through the control cabinet 9;

[0041] A liquid control mechanism 4 is provided at the front opening position of the atomizing nozzle of the main body 2 of the sprayer, and the spray stratification orientation is controlled through the liquid control mechanism 4. A guiding mechanism 5 is installed inside the nozzle of the main body 2 of the sprayer, and the air delivery guiding intensity is controlled through the guiding mechanism 5;

[0042] Among them, the main body 2 of the sprayer includes a nozzle, an air delivery mechanism and a delivery pipeline. The delivery pipeline is communicated with the pump body, and the liquid pumped through the nozzle 410 is driven to be ejected through the wind fan blades after being ejected.

[0043] The liquid control mechanism 4 includes a liquid control frame 401, and the liquid control frame 401 is connected to the outside of the nozzle opening of the sprayer main body 2. A plurality of liquid delivery sacs 402 are equidistantly arranged around the inner side of the nozzle of the sprayer main body 2 along the axis. The rear side of the liquid delivery sac 402 is connected to the pump body through a delivery pipeline. A plurality of nozzles 410 are arranged around the front side of the liquid delivery sac 402. The nozzles 410 are rotatably connected to the front side of the liquid delivery sac 402. A pull rod 411 is sleeved between a plurality of horizontally arranged nozzles 410 on one side of the liquid control frame 401. The pull rod 411 is slidably connected to the inside of the liquid control frame 401. The liquid spraying direction of the corresponding nozzles 410 is adjusted by the sliding of the pull rod 411 in the liquid control frame 401;

[0044] One end of the side of the pull rod 411 is rotatably connected to a connecting rod 412, and the other end of the connecting rod 412 is rotatably connected to a moving block 413. The moving block 413 is slidably connected to a chute opened on one side of the liquid control frame 401. A slider 414 is connected to one side of the liquid control frame 401. The slider 414 is slidably connected to the chute. A first pushing part 415 is connected to the bottom of the slider 414, and the first pushing part 415 is connected to the inside of the chute. The pull rod 411 is driven to move by the pushing of the first pushing part 415;

[0045] Among them, in order to maintain the moving stability of the pull rod 411, both sides of the pull rod 411 are slidably connected to the guide rails opened on the inner side of the liquid control frame 401 through guide blocks. Through the designed liquid delivery sac 402, the liquid friction noise during the delivery process can be reduced by the setting of the liquid delivery sac 402, and the comfort of the spraying environment can be improved.

[0046] Specifically: when a plurality of nozzles 410 are arranged around the front side of the sprayer main body 2, the nozzles 410 at the same horizontal position can be pulled and controlled by the pull rod 411. When the first pushing part 415 works to extend or shorten and pull the slider 414 to move, the movement of the slider 414 can drive the moving block 413 and the connecting rod 412 to move. The movement of the connecting rod 412 can drive the pull rod 411 on the other side to move. The movement of the pull rod 411 can drive the nozzles 410 to deviate around the moving direction of the pull rod 411. By adjusting the corresponding nozzles 410 in the horizontal position, the spraying direction of the sprayed water can be changed. When the opening direction of the sprayer main body 2 is fixed, by controlling the telescopic amount of the first pushing part 415, the angle of the nozzles 410 can be offset to change the water spraying trajectory, reduce the interference of environmental airflow, which is beneficial to intelligent spray water replenishment, spraying medicine or applying liquid fertilizer, etc. to facility vegetables with different plant height differences, improve the control accuracy of the spray amount on the roots or leaves of vegetables, and improve the atomization effect at the same time;

[0047] Furthermore, through multiple sets of pull rods 411 provided, multiple first pushing parts 415 can horizontally and independently adjust the spraying angle of the specific height nozzle 410. Without the need to adjust the orientation of the main body 2 of the sprayer as a whole, it can effectively control the axial spraying angle of the water mist in a partitioned manner, facilitating differential spraying and liquid supplementation for multi-level targets, and solving the problems of resource waste and uneven coverage caused by the overall angle adjustment of traditional fixed spraying equipment.

[0048] One side of the liquid delivery bladder 402 is communicated with a stabilizing frame 403. The top of the stabilizing frame 403 is rotatably connected with a turntable 404. One side of the turntable 404 close to the nozzle 410 is hinged to both outer sides of the nozzle 410 through two opposed support blocks 409, and the tail of the nozzle 410 is connected to the liquid delivery bladder 402 through a flexible pipe passing through the stabilizing frame 403;

[0049] One side of the turntable 404 is connected with a rotating block 405. The rotating block 405 is rotatably connected in an arc-shaped groove 408 opened on the inner side of the stabilizing frame 403. A guiding hole is opened on one side of the rotating block 405. A guiding rod 406 is slidably connected in the guiding hole. Both ends of the guiding rod 406 are respectively connected to corresponding positions on both sides of the inner cavity of the arc-shaped groove 408. A tuning spring 407 is sleeved on the outer part of the guiding rod 406. Both ends of the tuning spring 407 are respectively connected to corresponding positions of the rotating block 405 and one side of the inner cavity of the arc-shaped groove 408;

[0050] Among them, the arc-shaped groove 408 is an arc-shaped structure matching the rotation stroke of the rotating block 405, and the guiding rod 406 matches the arc of the inner cavity of the arc-shaped groove 408;

[0051] Specifically: when the pull rod 411 pulls the nozzle 410 to move, the nozzle 410 can rotate around the hinge position of the support block 409 to adapt to the angle adjustment of the liquid spraying direction. And when the pull rod 411 further pulls, the turntable 404 can rotate in the arc-shaped groove 408 through the top rotating block 405. Thus, through the respective rotations of the turntable 404 and the nozzle 410, it can better adapt to the angle deviation, maintain the controllability of the liquid spraying angle, and through the designed tuning spring 407 and guiding rod 406, the turntable 404 can rotate more stably through the external rotating block 405. And when the rotating block 405 moves, it can squeeze the external tuning spring 407. The tuning spring 407 can use its own elastic force to absorb the impact of the rotating block 405 and reset the turntable 404, thereby improving the rotation stability of the nozzle 410.

[0052] Please refer to Figure 2 and 3, the guiding mechanism 5 includes a guiding ring 501 which is connected to one side inside the main body 2 of the sprayer. A plurality of guiding covers 502 are arranged around the guiding ring 501 along the axis on one side. A plurality of air inlet slots 503 are formed in the guiding ring 501 at positions corresponding to the guiding covers 502. A plurality of shielding plates 504 are rotatably connected inside the guiding ring 501, and the plurality of shielding plates 504 are connected by a toothed ring 505, and a driving part 506 is externally engaged with the toothed ring 505;

[0053] Please refer to Figure 3 , 7 and 11, a plurality of closing mechanisms 7 are arranged in the inner cavity of the guiding ring 501 at positions corresponding to the air inlet slots 503. Through the closing mechanisms 7, the incoming air is guided to move towards the nozzle 410 side. The closing mechanism 7 includes a fitting part 701. One side of the fitting part 701 is connected with a guiding part 702. The front side of the guiding part 702 is conical. One side of the fitting part 701 is connected with a sliding sleeve 703. A sliding rod 704 is slidably connected inside the sliding sleeve 703. The top end of the sliding rod 704 is connected with a fixing block 706. The fixing block 706 is connected to the inner side of the guiding ring 501. A second spring 705 is sleeved outside the sliding rod 704, and two ends of the second spring 705 are respectively connected to corresponding positions on one side of the sliding sleeve 703 and the fixing block 706;

[0054] Specifically: through the designed guiding mechanism 5 and closing mechanism 7, when the motor of the driving part 506 drives the gear to drive the toothed ring 505 to rotate, the rotation of the toothed ring 505 can drive the inner shielding plate 504 to move, and the movement of the shielding plate 504 can open the gap of the bottom air inlet slot 503, so that the air inlet gap can be adjusted by closing the air inlet slot 503, facilitating the adjustment of the coverage range of the blowing spray and improving the adaptability;

[0055] Through the conically arranged guiding part 702, the introduced air can be accelerated and ejected under the conical limiting action of the guiding part 702 to improve the flow efficiency of the atomized liquid;

[0056] Among them, the driving part 506 is a motor and the corresponding gear set, and the motor should be a servo motor. The corresponding position of the shielding plate 504 is sensed by a position sensor to control the shielding accuracy.

[0057] Please refer to Figure 1 , the direction control mechanism 6 includes a second pushing part 601. One end of the second pushing part 601 is connected with a rotating part 602, and the other side of the rotating part 602 is connected to the bottom of the main body 2 of the sprayer. The bottom side of the second pushing part 601 is connected with a base 603. The base 603 is connected to the top of the vehicle body 1 through a steering mechanism, and the top of the steering mechanism is connected to the bottom side of the bracket 8.

[0058] Specifically, the second propulsion unit 601 is a push rod motor, which can adjust the height of the main body 2 of the sprayer by telescoping. Therefore, it is very important to select a suitable push rod motor. An electric push rod is a power-driven device that converts the rotational motion of an electric motor into the linear reciprocating motion of a push rod. It can be used as an actuator in various simple or complex technological processes to achieve precise control, centralized control, or automatic control, without the cumbersome and complex hydraulic regulation, facilitating control. Moreover, the first propulsion unit 415 is also a corresponding push rod motor;

[0059] Furthermore, the spray device controls the liquid flow through a diaphragm pump, atomizes the liquid into droplets, and distributes the droplets on the surface of the target to achieve automatic control. The nozzle 410 is the terminal component for the sprayer to perform the spraying operation. The size of the nozzle 410 refers to the flow rate of the nozzle under a certain spraying pressure. The size of the spray hole and the pressure determine the flow rate. Adaptive selection is made according to the size of the spray hole, the liquid pressure, the traveling speed of the spraying equipment, and the height of the nozzle from the ground;

[0060] Regarding the vehicle body, the roads in the greenhouse are relatively flat compared to other environments, and the movement during operation is relatively simple, but precise control is required, and the mobility is relatively high. Therefore, the track-type autonomous walking method is adopted. The overall structure of the electric self-propelled chassis adopts a single-track design scheme, and the power scheme is two-wheel drive and differential steering. Among them, the drive wheels are arranged on both sides in the middle of the chassis, and one steerable driven track wheel is arranged at the front and rear respectively. It has a small turning radius, is flexible in movement, saves the limited activity space in the greenhouse, and only one track needs to be laid, which is simple and economical;

[0061] During the spraying process, the coordination of self-walking and spraying can be controlled by an intelligent control system. According to the actual morphology, size, density, row spacing, and plant spacing of the facility vegetables, the acquisition and analysis of these data can rely on corresponding sensors and image recognition analysis systems, etc., without specific elaboration.

[0062] In a preferred embodiment, the greenhouse intelligent trolley uses a 24V low voltage drive. The speed does not need to be too high, and it can save the battery power. Therefore, the drive system of the electric self-propelled chassis selects the MY1025 DC motor drive axle. During normal movement, the power of the drive motor is determined by the self-weight of the electric self-propelled chassis and its load. The maximum power required is:

[0063] P = F * V

[0064] F - Friction force (N);

[0065] v - Maximum speed (m / s).

[0066] The friction force received during the movement is:

[0067] F = (M1 + M2) * g * f

[0068] M1—Self-weight (kg);

[0069] M2—Load (kg);

[0070] f—Coefficient of friction, taking 0.25.

[0071] According to the design requirements, the MY1025 drive motor is adopted. The mass of the electric self-propelled chassis is regarded as the self-weight of 25 kg. When operating with the spraying module, the spraying module is regarded as the load, and the maximum load of the liquid medicine is set to 45 kg. The maximum traveling speed v = 0.5 m / s. Substituting the parameters into the formula, the required maximum power P of the drive system can be calculated as 85.75 W. Considering issues such as motor efficiency and kinetic energy loss, the MY1025 DC motor with a rated power of 100 W is selected as the drive motor.

[0072] In the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance; the term "plurality" means two or more, unless otherwise clearly defined. Terms such as "installed", "connected", "joined", "fixed", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; "joined" can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0073] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
