Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted sprayer technology, and in particular to a self-cleaning device for anti-clogging nozzles of vehicle-mounted sprayers. Background Technology

[0002] Vehicle-mounted sprayers are widely used in urban road dust suppression, agricultural and forestry pest and disease control, environmental sanitation and dust suppression in mining areas, and have significant advantages, especially in open areas or mobile operation scenarios. Vehicle-mounted sprayers mainly achieve functions such as air purification, temperature and humidity regulation, and neutralization of harmful substances by atomizing liquid into micron-sized particles and spreading them to the target area.

[0003] Existing vehicle-mounted sprayers mainly consist of a power system and nozzles. The power system often uses a diesel engine or electric motor to drive a high-pressure plunger pump, which pressurizes the liquid in the storage tank and finally sprays it out through the nozzles. In order to expand the spray range, such equipment is generally equipped with a nozzle longitudinal rotation mechanism, which makes it difficult to adjust the nozzle height, resulting in poor operational adaptability of the equipment. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a vehicle-mounted sprayer anti-clogging nozzle self-cleaning device, which aims to improve the problems of existing equipment being unable to adapt to nozzle height and having poor equipment operation adaptability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle-mounted sprayer anti-clogging nozzle self-cleaning device, comprising a base, a transmission gear rotatably connected to the left side of the base, a screw fixedly connected to the top of the transmission gear, a positioning block threadedly connected to the surface of the screw, a motor fixedly connected to the top of the positioning block, a rotating gear fixedly installed at the output end of the motor, the rotating gear meshing with a gear shaft, a nozzle fixedly connected to the front side of the gear shaft, a second motor fixedly connected to the left side of the base, a worm fixedly installed at the output end of the second motor, the worm meshing with the transmission gear, a sliding groove provided on the right side of the base, a cleaning mechanism provided on the inner wall of the sliding groove, the cleaning mechanism being used to clean the nozzle.

[0006] Preferably, the cleaning mechanism includes a movable seat, the bottom of which is slidably connected to the inner wall of the chute, a brush head is fixedly connected to the top of the movable seat, a rotating shaft is fixedly connected to the middle surface of the brush head, a spring is sleeved on the surface of the rotating shaft, and a guide plate is fixedly connected to the top of the spring.

[0007] Preferably, a push rod motor is fixedly connected to the right side surface of the base, and the output end of the push rod motor is fixedly connected to the movable base.

[0008] Preferably, the bottom end of the spring is fixedly connected to the surface of the brush head, a fixing plate is fixedly connected to the middle surface of the brush head, and the middle part of the guide plate is rotatably connected to the fixing plate.

[0009] Preferably, a fixing block is fixedly connected to the top of the base, and the fixing block is rotatably connected to the worm gear.

[0010] Preferably, the base has a housing fixedly connected to the top left side, and the surface of the positioning block is in contact with the inner wall of the housing.

[0011] Preferably, the inner side of the positioning block is rotatably connected to both the nozzle and the gear shaft.

[0012] Preferably, a timer is installed inside the nozzle, which is used to send a signal to start the cleaning mechanism at fixed intervals.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, starting motor two causes the worm and rotating screw to rotate simultaneously. The positioning block is threadedly connected to the screw to move the nozzle up and down. Starting motor one allows the nozzle to rotate around the positioning block, thus realizing motor one controlling the nozzle to rotate around the positioning block. Through the joint control of motor two and motor one, dual-degree-of-freedom adjustment of the nozzle is achieved, improving the operational adaptability of the equipment while ensuring uniform spray volume per unit area.

[0015] 2. In this utility model, when the nozzle needs to be cleaned, the cleaning mechanism is moved along the slide groove to the right side of the nozzle by starting the push rod motor, so that the guide plate and the fixed plate are in contact, thereby assisting the cleaning brushes that are evenly distributed on the surface of the brush head to enter the inside of the nozzle for cleaning, avoiding the phenomenon of nozzle hole clogging caused by long-term spraying of high viscosity agents, and extending the service life of the nozzle.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-4 An embodiment of this utility model provides a vehicle-mounted sprayer anti-clogging nozzle self-cleaning device, including a base 1. A transmission gear 3 is rotatably connected to the left side of the base 1. A screw 6 is fixedly connected to the top of the transmission gear 3. A positioning block 5 is threadedly connected to the surface of the screw 6. A motor 8 is fixedly connected to the top of the positioning block 5. A rotating gear 7 is fixedly installed at the output end of the motor 8. A gear shaft 9 is meshed with the rotating gear 7. A nozzle 2 is fixedly connected to the front side of the gear shaft 9. A second motor 11 is fixedly connected to the left side of the base 1. A worm gear 4 is fixedly installed at the output end of the second motor 11. The worm gear 4 is meshed with the transmission gear 3. A sliding groove 16 is opened on the right side of the base 1. A cleaning mechanism is provided on the inner wall of the sliding groove 16. The cleaning mechanism is used to clean the nozzle 2.

[0024] By starting motor 11, the worm gear 4 is rotated. Since both ends of the worm gear 4 are meshed with the transmission gear 3, and the top of the transmission gear 3 is fixedly connected to the screw 6, the worm gear 4 rotates and the screw 6 rotates simultaneously. The positioning block 5 is threadedly connected to the screw 6, allowing motor 11 to control the up and down movement of the nozzle 2. By starting motor 8, the rotating gear 7 drives the gear shaft 9 to rotate together. The gear shaft 9 is fixedly connected to the nozzle 2, allowing the nozzle 2 to rotate around the positioning block 5. This enables motor 8 to control the nozzle 2 to rotate around the positioning block 5. Through the joint control of motor 11 and motor 8, when suppressing dust on roads, the nozzle 2 is raised to expand the fog coverage area, thereby reducing the droplet settling speed and extending the suspension time. In near-ground disinfection operations, the height of the nozzle 2 is lowered to reduce wind interference, thereby improving the local area's pesticide deposition rate.

[0025] Reference Figure 4The cleaning mechanism includes a movable base 13, the bottom of which is slidably connected to the inner wall of the slide groove 16. A brush head 14 is fixedly connected to the top of the movable base 13, and a rotating shaft 17 is fixedly connected to the middle surface of the brush head 14. A spring 18 is sleeved on the surface of the rotating shaft 17, and a guide plate 19 is fixedly connected to the top of the spring 18. When the nozzle 2 needs to be cleaned, the direction of the nozzle 2 is adjusted by the second motor 11 and the first motor 8, so that the top of the nozzle 2 faces to the right. The guide plate 19 assists the evenly distributed cleaning brushes on the surface of the brush head 14 to enter the interior of the nozzle 2 for cleaning, avoiding the phenomenon of nozzle 2 being clogged due to long-term spraying of high-viscosity agents, thus extending the service life of the nozzle 2.

[0026] Reference Figure 1 A push rod motor 12 is fixedly connected to the right side surface of the base 1. The output end of the push rod motor 12 is fixedly connected to the moving base 13. By starting the push rod motor 12, the cleaning mechanism moves along the slide 16 to the right side of the nozzle 2, thereby allowing the cleaning brush on the surface of the cleaning mechanism to enter the interior of the nozzle 2.

[0027] Reference Figure 4 The bottom end of the spring 18 is fixedly connected to the surface of the brush head 14. A fixing plate 20 is fixedly connected to the middle surface of the brush head 14. The middle part of the guide plate 19 is rotatably connected to the fixing plate 20. Since the top slot of the guide plate 19 is connected to the rotating shaft 17 and the top is rotatably connected to the fixing plate 20, the guide plate 19 can fit against the fixing plate 20 under the action of the spring 18, thus realizing the guiding function of the guide plate 19.

[0028] Reference Figure 2 A fixing block 10 is fixedly connected to the top of the base 1. The fixing block 10 is rotatably connected to the worm 4. The worm 4 is rotatably connected to multiple fixing blocks 10 so that the worm 4 can obtain a certain support force, thereby avoiding the worm 4 from deviating when rotating, which would cause problems in the operation of the equipment.

[0029] Reference Figure 2 The base 1 has a housing 15 fixedly connected to the top left side. The surface of the positioning block 5 is in contact with the inner wall of the housing 15. The positioning block 5 moves up and down inside the housing 15, so that the housing 15 ensures that the positioning block 5 is always perpendicular to the ground along the direction of the housing 15 when it moves, thus providing support for the nozzle 2 when adjusting the height of the nozzle 2.

[0030] Reference Figure 3The inner side of the positioning block 5 is rotatably connected to both the nozzle 2 and the gear shaft 9. Through the rotatable connection between the positioning block 5 and the nozzle 2, the positioning block 5 can move along the direction of the screw 6 when the screw 6 rotates, thereby enabling the motor 11 to start and control the nozzle 2 to move up and down. At the same time, through the rotatable connection between the inner side of the positioning block 5 and the nozzle 2, the nozzle 2 can rotate around the positioning block 5, thereby enabling the motor 18 to control the nozzle 2 to rotate around the positioning block 5, thus realizing the dual-degree-of-freedom adjustment of the nozzle 2.

[0031] Reference Figure 1 The nozzle 2 is equipped with a timer, which sends a signal at fixed times to start the cleaning mechanism. The timer uses a microprocessor control circuit board and can preset time intervals. The timer automatically triggers the timing control of the cleaning program, ensuring that the nozzle 2 performs self-cleaning actions within a fixed cycle, thereby avoiding clogging problems caused by the accumulation of spray residue.

[0032] Working principle: By starting the motor 11, the worm 4 is rotated. Since both ends of the worm 4 are meshed with the transmission gear 3, and the top of the transmission gear 3 is fixedly connected to the screw 6, the worm 4 rotates and the screw 6 rotates at the same time. The positioning block 5 is threadedly connected to the screw 6 and is rotatably connected to the nozzle 2. When the screw 6 rotates, the positioning block 5 can move along the direction of the screw 6, thereby enabling the motor 11 to control the up and down movement of the nozzle 2.

[0033] Since the inner side of the positioning block 5 is rotatably connected to the nozzle 2, by starting the motor 8, the rotating gear 7 drives the gear shaft 9 to rotate together. The gear shaft 9 is fixedly connected to the nozzle 2, so that the nozzle 2 can rotate around the positioning block 5. Thus, the motor 8 controls the nozzle 2 to rotate around the positioning block 5. Through the joint control of the motor 11 and the motor 8, the nozzle 2 is adjusted with two degrees of freedom, which improves the operational adaptability of the equipment and ensures uniform spray volume per unit area.

[0034] When the nozzle 2 needs to be cleaned, the direction of the nozzle 2 is adjusted by motor 2 11 and motor 1 8, so that the top of the nozzle 2 faces to the right. The cleaning mechanism is moved to the right side of the nozzle 2 by starting the push rod motor 12. Since the top slot of the guide plate 19 is connected to the rotating shaft 17 and the top is rotatably connected to the fixed plate 20, the guide plate 19 can fit against the fixed plate 20 under the action of the spring 18, realizing the guiding function of the guide plate 19. The guide plate 19 assists the cleaning brushes evenly distributed on the surface of the brush head 14 to enter the interior of the nozzle 2 for cleaning, avoiding the phenomenon of nozzle 2 being clogged due to long-term spraying of high-viscosity agents, thus extending the service life of the nozzle 2.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
