Description

Technical Field

[0002] A spraying device is short for spraying equipment. It's used in fruit and vegetable cultivation to spray pesticides, a crucial step in the process. Traditionally, pesticide spraying in agriculture mostly uses sprayers, which operate on the principle of using air suction to atomize pesticides or other liquids, spraying them evenly onto objects. These sprayers consist of a compressed air unit, a fine tube, and nozzles. In rural areas, sprayers are indispensable tools for pest and disease control. Currently, two types of sprayers are widely used in field crops and fruit and vegetable cultivation: backpack hand-cranked sprayers and mechanical electric sprayers. Backpack hand-cranked sprayers are mostly used for small areas of crops and are manually operated; for large areas of crops, mechanical electric sprayers are mostly driven by an electric motor.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figures 1 to 4 As shown, the present invention provides a pesticide spraying device for fruit and vegetable planting, including a housing 1. A mixer is installed inside the housing 1. The liquid inlet of the mixer is connected to a water tank 15 and a pesticide tank 14 through two pipes, one of which is a rigid pipe 16 and the other is a rigid pipe 27. Both the rigid pipe 16 and the rigid pipe 27 are equipped with flow valves. The liquid outlet of the mixer is connected to a stirring mechanism. The stirring mechanism is connected to a spray bar 19 through a hose. The liquid outlet of the spray bar 19 is threadedly connected to an atomizing nozzle 22. A filter mechanism is installed on the spray bar 19 to intercept impurities in the liquid inside the spray bar 19.

[0027] The flow rate of water and chemicals flowing into the mixer can be controlled separately by the flow valve, thereby achieving a precise ratio of chemicals to liquid. The mixer mixes the water and chemicals and the stirring mechanism mixes them thoroughly. The high pressure provided by the water pump 2 causes the mixed liquid filtered by the filtration mechanism to be sprayed onto the fruits and vegetables through the atomizing nozzle 22.

[0028] Furthermore, the mixer includes a tube 44 with a rectangular cross-section. Multiple baffles 45 are evenly spaced on opposite sidewalls of the tube 44 and are staggered. The inner cavity of the tube 44 is divided by the multiple baffles 45 to form a serpentine flow channel. The reagent tank 14 and the water tank 15 are both connected to the inlet end of the serpentine flow channel. The outlet end of the serpentine flow channel is connected to the inlet end of the water pump 18, and the outlet end of the water pump 18 is connected to the stirring mechanism.

[0029] The serpentine flow channel allows water and chemicals to constantly change direction within the channel. This flow pattern helps the two liquids with different speeds and masses to come into full contact, thereby improving the mixing effect.

[0030] Furthermore, the stirring mechanism includes a housing 3, a motor 13 is installed at the top of the housing 3, the output end of the motor 13 is connected to one end of a rotating rod 12, the other end of the rotating rod 12 passes through the top wall of the housing 3 and extends into the housing 3, a plurality of stirring blades 11 are connected at equal intervals along the circumference of the rotating rod 12, the bottom end of the housing 3 is connected to the inlet end of a second water pump 18, and the outlet end of the second water pump 18 is connected to a spray bar 19 through a hose.

[0031] The motor 13 drives the rotating rod 12 and the stirring blade 11 to rotate, which fully stirs the mixture of medicine and water, further improving the mixing effect of the two liquids.

[0032] Furthermore, the filtration mechanism includes a drive unit and a filtration assembly. The filtration assembly includes a housing 24 connected to the spray bar 19. The housing 24 has a circular cross-section. The top of the housing 24 is connected to a slag discharge pipe 21, and the bottom of the housing 24 is provided with a plug 31. Both the slag discharge pipe 21 and the plug 31 are perpendicular to the spray bar 19. A water circuit switching unit is rotatably connected inside the housing 24. The drive unit is used to drive the water circuit switching unit to switch water circuits.

[0033] The water circuit inside the housing 24 is switched by driving the water circuit switching unit through the drive unit, so that the end with the impurities is connected to the slag discharge pipe 21, and the liquid in the spray bar 19 is reversed to flush down the impurities and discharged from the slag discharge pipe 21 by switching the water circuit.

[0034] Furthermore, the water circuit switching unit includes a valve core 27 coaxially rotatably connected within the housing 24. The valve core 27 is circumferentially provided with an inlet chamber 28, an inlet chamber 30, and an outlet chamber 23. Both the inlet chamber 28 and the inlet chamber 30 are connected to the outlet chamber 23. The angle between the inlet chamber 28 and the outlet chamber 23 is 180 degrees, and the angle between the inlet chamber 30 and the inlet chamber 28 is 90 degrees. The inlet chamber 30 is located below the inlet chamber 28. A filter screen 29 is provided on the inlet chamber 28, and a filter screen 32 is provided on the inlet chamber 30.

[0035] When it is necessary to clean the impurities on filter screen 29, drive valve core 27 to rotate 90 degrees clockwise, so that filter screen 29 is aligned with slag discharge pipe 21. At this time, filter screen 32 is aligned with the liquid outlet end of spray bar 19, and liquid outlet chamber 23 is blocked by plug 31. Liquid enters through liquid inlet chamber 30 and is sprayed out from liquid inlet chamber 28, impacting filter screen 29 in the opposite direction, so that the intercepted impurities are instantly discharged through slag discharge pipe 21. After the impurities are cleaned, valve core 27 rotates 90 degrees counterclockwise to reset. Liquid inlet chamber 28 is connected to the water outlet end of spray bar 19, liquid outlet chamber 23 is connected to atomizing nozzle 22, and liquid inlet chamber 30 is blocked by plug 31.

[0036] Furthermore, the drive unit includes a piston cylinder 20 mounted on the spray bar 19. A piston 34 is slidably mounted inside the piston cylinder 20. The piston cylinder 20 is divided by the piston 34 to form a hydraulic chamber. An inlet hole 33 is provided on the side wall of the piston cylinder 20. The hydraulic chamber is connected to the spray bar 19 through the inlet hole 33. One end of a piston rod 36 is connected to the middle of the piston 34. The other end of the piston rod 36 passes through the side wall of the piston cylinder 20 and is provided with a transmission assembly. A spring 35 is slidably mounted on the piston rod 36. One end of the spring 35 abuts against the side of the piston 34 away from the housing 24, and the other end of the spring 35 abuts against the inner wall of the piston cylinder 20. The transmission assembly is used for the transmission connection between the piston rod 36 and the valve core 27.

[0037] When a certain amount of liquid accumulates on the filter screen 29, the liquid enters the hydraulic chamber through the inlet hole 33 and pushes the piston 34 to move away from the housing 24, overcoming the elastic force of the spring 35. The piston rod 36 extends continuously and drives the valve core 27 to rotate through the transmission assembly, thus completing the switching of the water circuit.

[0038] Furthermore, a rotating shaft 25 is rotatably connected to the middle of the housing 24. One end of the rotating shaft 25 is connected to the valve core 27, and the other end of the rotating shaft 25 is connected to the winding wheel 26. A reset torsion spring is sleeved on the rotating shaft 25. One end of the reset torsion spring is connected to the winding wheel 26, and the other end of the reset torsion spring is connected to the housing 24.

[0039] Furthermore, the transmission assembly includes a fixed pulley 37 rotatably connected to the spray bar 19, a winding wheel 26 on which one end of a rope is wound, and the other end of the rope passes around the fixed pulley 37 and is connected to the piston rod 36.

[0040] Specifically, the piston rod 36 extends continuously, pulling the rope. The rope changes direction through the fixed pulley 37 and pulls the winding wheel 26 to rotate clockwise against the torque of the return spring. The rotation angle of the valve core 27 is controlled by the length of the rope, that is, the length of the rope is just enough to allow the valve core 27 to rotate 90 degrees. After the impurities are cleaned, the liquid pressure in the spray bar 19 drops, the piston 34 is reset under the rebound force of the spring 35, the piston rod 36 retracts, the valve core 27 is reset under the action of the return torsion spring, and the rope is wound back onto the winding wheel 26.

[0041] Furthermore, the bottom end of partition 2 45 is connected to multiple elastic strips 46.

[0042] The addition of elastic strips 46 within the serpentine flow channel alters the flow path and velocity distribution of the reagent and water. The oscillation of the elastic strips 46 induces more convection and collision between the two liquids within the serpentine flow channel, thereby promoting liquid mixing. This design not only improves mixing efficiency but also reduces the mixing time required.

[0043] Furthermore, a partition 6 is horizontally arranged inside the housing 3. The housing 3 is divided into a mixing chamber and a buffer chamber from top to bottom by the partition 6. A water level control component is provided on the partition 6. The water level control component is used to control the height of the liquid level in the buffer chamber. The buffer chamber is connected to the inlet end of the water pump 18.

[0044] The buffer chamber buffers the well-mixed liquid and supplies it for spraying. When the level in the buffer chamber falls below a preset minimum, a water level control component replenishes the buffer chamber with liquid from the mixing chamber. This design ensures the supply of pesticide solution during spraying while simultaneously agitating the initially mixed liquid flowing out of the mixer, achieving thorough mixing. These two processes operate independently.

[0045] Furthermore, the water level control assembly includes a cylinder 7 fixedly connected to the top of a partition 6. A sliding rod 8 is slidably and sealingly connected to the middle of the partition 6. The top of the sliding rod 8 extends into the cylinder 7 and is connected to a circular plate 10. Multiple wedge-shaped blocks 9 are evenly spaced around the circular plate 10. Multiple sealing components are evenly spaced around the bottom of the cylinder 7. Each sealing component includes a sliding rod 39 slidably connected to the outer wall of the cylinder 7. One end of the sliding rod 39 is connected to a sealing plate 38, and the other end is connected to a wedge-shaped block 42. Block 2 42 is adapted to wedge block 1 9. Spring 2 41 is slidably sleeved on slide rod 2 39. One end of spring 2 41 abuts against wedge block 2 42, and the other end of spring 2 41 abuts against the groove wall of the groove opened on the inner wall of cylinder 7. Multiple water-permeable holes 40 are opened on cylinder 7. Multiple water-permeable holes 40 are arranged along the circumference of slide rod 2 39. Sealing plate 38 is used to seal water-permeable holes 40. The bottom end of slide rod 1 8 extends into the buffer cavity and is connected to float plate 4. Multiple guide pipes 43 are provided on partition plate 1 6. Guide pipes 43 are used to connect buffer cavity and inner cavity of cylinder 7.

[0046] Specifically, as the liquid level falls, the float 4 moves the slide bar 8, the circular plate 10, and the wedge block 9 downwards. When the liquid level in the buffer chamber is below the safe water level, the wedge block 9 squeezes the wedge block 42. The wedge block 42 squeezes the spring 41 and causes the slide bar 39 to slide, causing the sealing plate 38 to lose its sealing of the permeable hole 40. The liquid in the mixing chamber enters the cylinder 7 and enters the buffer chamber through the guide pipe 43 for replenishment. As the liquid level in the buffer chamber rises, the rising liquid level contacts the float 4, and the float 4 is buoyed and lifts the slide bar 8 upwards, forcing the wedge block 9 to separate from the wedge block 42. The sealing plate 38 resets under the action of the spring 41 and seals the permeable hole 40.

[0047] The pesticide spraying device for fruit and vegetable cultivation provided by this invention works as follows: When in use, water is added to the water tank 15, liquid pesticide is added to the pesticide tank 14, and the water pump 18 is started. The two liquids are initially mixed by the mixer under the suction of the water pump 18 and enter the mixing chamber in the tank 3. They are then fully mixed by the stirring mechanism and replenished to the buffer chamber by the water level control component. The mixture is then sprayed onto the fruits and vegetables through the atomizing nozzle 22 after being filtered by the filtration mechanism under the high pressure provided by the water pump 2.

[0048] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.
