Description

Technical Field

[0001] This utility model relates to the field of tobacco planting technology, and in particular to a spray bottle for tobacco planting. Background Technology

[0002] During the tobacco growing season, tobacco farmers need to constantly observe whether the tobacco leaves are affected by pests and diseases. Once they are found, pesticides should be applied in time to ensure the healthy growth of the tobacco plants and avoid situations where the yield of tobacco leaves drops sharply or even large areas die due to pests and diseases.

[0003] A search revealed a Chinese patent publication number, CN222090617U, which discloses a small portable sprayer for tobacco cultivation. This patent involves pouring the pesticide solution to be sprayed into a water tank and rotating a shaft to stir the pesticide solution in the water tank. However, this device has certain problems: the pesticide solution is mixed slowly due to the horizontal rotation of the stirring paddle alone. If the pesticide solution is not mixed evenly, it may lead to high local concentrations of pesticide, which could cause pesticide damage. Utility Model Content

These air outlet pipes 406 are evenly distributed in a vortex pattern along the circumference of the connecting cavity 405. The end of each air outlet pipe 406 away from the connecting cavity 405 is inclined towards the bottom wall of the water tank 201. Pressing down on the sliding column 403 causes the return spring 404 to deform, and simultaneously, the sliding column 403 pushes the air inside the fixed tube 401 downwards, allowing the air inside the fixed tube 401 to pass through... The airflow enters the connecting cavity 405 through the through hole, and then enters the water tank 201 through the air outlet pipe 406, causing the airflow to vortex and stir the liquid in the water tank 201. At the same time, the airflow is sprayed at an angle, so that the medicine and water in the water tank 201 can mix vertically. After the sliding column 403 is released, the return spring 404 restores its deformation and drives the sliding column 403 to move upward. When the lower end of the sliding column 403 rises above the air inlet 402, air enters the fixed pipe 401. Continuously pressing the sliding column 403 causes the airflow to continuously enter the water tank 201 to form a vortex, which accelerates the mixing of the medicine.

[0029] Symmetrical retaining rings 301 are hinged on both sides of the partition 101. The retaining rings 301 are located on the side of the water tank 201 away from the partition 101. The symmetrical retaining rings 301 are semi-circular with openings close to the partition 101.

[0030] Multiple equidistant anti-slip blocks 302 are fixedly connected to the side of the retaining ring 301 near the partition 101. A locking knob 303 is threadedly connected to the end of the retaining ring 301 away from the partition 101. When in use, the water tank 201 is placed on the supporting ring 102, and then the retaining rings 301 on both sides are rotated to make the anti-slip blocks 302 press against the outside of the water tank 201. Then the locking knob 303 is rotated to fix the retaining rings 301 on both sides.

[0031] Symmetrical shoulder straps 501 are fixedly connected to both sides of the partition 101. The shoulder straps 501 are located at the rear end of the partition 101. A bracket 502 is provided below the shoulder straps 501. The bracket 502 is fixedly connected to the rear end of the partition 101. A fixing knob 503 is threadedly connected to the bracket 502.

[0032] A waist belt 601 is fixedly connected to one side of the partition 101, and a connecting seat 602 is fixedly connected to the side of the partition 101 away from the waist belt 601. The waist belt 601 is provided with a Velcro assembly. The movable end of the waist belt 601 is passed through the connecting seat 602, and then the waist belt 601 is fixed to the user's abdomen by the Velcro assembly.

[0033] A connecting hose 701 is fixedly connected to the bottom of the water tank 201. A water pump is provided between the connecting hose 701 and the water tank 201. A nozzle 702 is fixedly connected to the end of the connecting hose 701 away from the water tank 201. The user holds the end of the nozzle 702 and then uses the connecting hose 701 to transport the liquid to the nozzle 702 and spray it onto the tobacco leaves.

[0034] A feed pipe 202 is fixedly connected to the top of the water tank 201. The feed pipe 202 is located on one side of the water tank 201. A pipe cap is threadedly connected to the upper end of the water tank 201. The medicine is poured into the water tank 201 through the feed pipe 202.

[0035] Working principle: When spraying pesticide, the pesticide solution is poured into the water tank 201 through the feed pipe 202 for dilution. Then, the sliding column 403 is pressed down, causing the return spring 404 to deform. At the same time, the sliding column 403 pushes the air in the fixed pipe 401 downward, allowing the air in the fixed pipe 401 to enter the connecting cavity 405 through the through hole. Subsequently, the airflow enters the water tank 201 through the air outlet pipe 406, causing the airflow to vortex and agitate the liquid in the water tank 201. Simultaneously, the airflow is sprayed at an angle, allowing the pesticide solution and water in the water tank 201 to mix vertically. After releasing the sliding column 403, the return spring 404 returns to its original deformation, causing the sliding column 403 to move upward. When the lower end of the sliding column 403 rises above the air inlet 402, air enters the fixed pipe 401. Continuing to press the sliding column 403... The airflow continuously enters the water tank 201, forming a vortex to accelerate the mixing of the medicine. Then, the tube cap is rotated to seal it and prevent the medicine from evaporating. The water tank 201 is then placed on the support ring 102. The two side rings 301 are then rotated to make the anti-slip block 302 press against the outside of the water tank 201. Then, the locking knob 303 is rotated to fix the two side rings 301. The length of the shoulder strap 501 is adjusted according to the user's comfort. After adjustment, the fixing knob 503 is rotated to fix the length of the shoulder strap 501. Then, the partition 101 is carried on the back, and the movable end of the waist belt 601 is passed through the connecting seat 602. Then, the waist belt 601 is fixed to the user's abdomen through the Velcro assembly. The user holds the end of the nozzle 702 and then delivers the liquid to the nozzle 702 through the connecting hose 701 and sprays it onto the tobacco leaves.
