A pesticide spraying device

Abstract

The present invention discloses a pesticide spraying device, which comprises a bracket, a disc and a rotary nozzle. The disc is fixedly connected to the bracket, and the rotary nozzle is rotatably connected to the bracket through its top. A blade is arranged at the lower end of the rotary nozzle. The disc is sleeved on the rotary nozzle through a through hole. The liquid spraying port of the rotary nozzle is located above the disc, and the blade is located below the disc. A plurality of small holes are formed in the disc, and a leveling rod is horizontally and fixedly arranged on the rotary nozzle. The leveling rod is in contact with the upper surface of the disc. The cavity of the rotary nozzle is communicated with the water outlet of a water pump through a water pipe, and the water inlet of the water pump is communicated with a liquid storage barrel. The water pipe is rotationally and hermetically connected to the bottom of the rotary nozzle. A liquid insecticide is stored in the liquid storage barrel. By adding bubble water to the prepared lime sulfur mixture, the liquid insecticide forms bubbles. Since the bubbles are small in mass and large in volume, they have good diffusion characteristics and can disperse in all directions, providing sufficient pesticide coverage for crops. In addition, by foaming, pesticides can be saved more effectively.

Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural equipment, and particularly relates to a pesticide spraying device. Background Art

[0002] Because the branches and leaves of crops are lush, the lower leaves will be blocked and covered by the upper ones. When farmers spray pesticides, they often need to spray once from the upper part of the plant, then turn the nozzle and spray again from the lower part of the plant; if only the upper part or only the lower part is sprayed, the insecticidal efficiency will drop significantly. However, whether it is sprinkler irrigation or micro-sprinkler irrigation, it still cannot spray in all directions. When spraying from the upper part, the lower leaves cannot be sprayed; when sprinkler irrigation is carried out from the lower part, it is difficult to pass through the leaves. When the crops are relatively tall, it is difficult to spray pesticides to the top of the fruit trees using bottom sprinkler irrigation; and currently, the efficiency of spraying pesticides using sprinkler irrigation is very low, even lower than manual spraying. Usually, for one mu of land, 60 kilograms of diluted pesticides are required. Summary of the Invention

[0003] The purpose of the present invention is to provide a pesticide spraying device to solve the technical problems in the prior art that when farmers spray pesticides, whether it is sprinkler irrigation or micro-sprinkler irrigation, it still cannot spray in all directions, and the current efficiency of spraying pesticides using sprinkler irrigation is low.

[0004] To solve the above technical problems, the technical solution of the present invention is as follows:

[0005] A pesticide spraying device includes a bracket, a disc and a rotating nozzle. The disc is fixedly connected to the bracket, and a through hole is provided at the center of the disc; the rotating nozzle is rotationally connected to the bracket through its top, and blades are provided at the lower end of the rotating nozzle. The disc is sleeved on the rotating nozzle through the through hole. The disc is horizontally arranged, and there is a gap between the rotating nozzle and the inner wall of the through hole, and they are not connected; wherein, the liquid spraying port of the rotating nozzle is located above the disc, and the blades are located below the disc;

[0006] A plurality of small holes are provided on the disc, and a leveling rod is horizontally and fixedly arranged on the rotating nozzle. The leveling rod is in contact with the upper surface of the disc but not connected;

[0007] The cavity of the rotating nozzle is communicated with the water outlet of the water pump through a water pipe. The water inlet of the water pump is communicated with a liquid storage barrel; the water pipe is rotationally and hermetically connected to the bottom of the rotating nozzle; liquid insecticide is stored in the liquid storage barrel.

[0008] Further improvement, the components of the liquid insecticide include lime sulfur mixture and bubble water. Calculated by mass percentage, 28-degree Baume lime sulfur mixture: bubble water = 1:39;

[0009] The components of the bubble solution include skin care glycerin, single-component ethyl α-cyanoacrylate glue, water, and household laundry detergent. Calculated by mass percentage, skin care glycerin: single-component ethyl α-cyanoacrylate glue: water: household laundry detergent = 1:1:4:4.

[0010] Add the liquid insecticide into the liquid storage bucket, turn on the water pump, and the water pump transports the liquid insecticide through the water pipe into the cavity of the spray head. Since the liquid spraying port is inclined, when the high-pressure liquid insecticide entering the cavity sprays out from multiple liquid spraying ports, the generated thrust causes the spray head to rotate relative to the bracket. By changing the water pressure of the water pump, the liquid insecticide is sprayed onto the disc, and the spreading rod rotates with the spray head to evenly spread the liquid falling on the disc into a thin film; the blades rotate with the spray head to generate an upward airflow, and the airflow passes through several small holes on the disc to blow the liquid insecticide film to form bubbles, which disperse in all directions. When the bubbles fall onto the crops, they explode at different positions, and the scattered pesticide liquid gives the crops sufficient pesticide coverage.

[0011] By adding the bubble solution to the prepared lime sulfur mixture and setting the rotary spray head, disc, spreading rod, and blades, the liquid insecticide forms bubbles. Since the bubbles are small in mass and large in volume, they have good diffusion characteristics and can disperse in all directions, giving the crops sufficient pesticide coverage; in addition, through foaming, pesticides can be saved more.

[0012] Further improvement: The bracket includes a cross beam and a frame suspended on the cross beam. The frame includes a top plate and two vertical plates, and is in an inverted U shape as a whole. The top plate is connected to the cross beam through a suspension rod. The upper ends of the two vertical plates are connected to the two ends of the top plate, and the lower ends are connected to the disc. The top of the rotary spray head is rotationally connected to the top plate through a bearing.

[0013] Further improvement: A baffle is fixedly arranged on the rotary spray head. The baffle is located below the liquid spraying port and above the disc, and the baffle is inclined upward.

[0014] By setting the baffle, after the blades rotate with the rotary spray head, an upward airflow is generated. The wind blowing upward from the gap between the rotary spray head and the inner wall of the through hole changes direction when it encounters the baffle, and part of the wind blows outward in the horizontal direction, giving the bubbles a horizontal initial velocity, making the pesticide bubbles float farther and blowing to all corners of the crops. The pesticide spraying area is increased.

[0015] Further improvement: The bracket, disc, and rotary spray head are all made of plastic, which is cheap, and can be recycled and reused after recycling and replaced.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] By adding bubble water to the prepared lime sulfur mixture and setting up a rotating nozzle, a disc, a spreading rod and blades, the liquid insecticide forms bubbles. Since the bubbles are small in mass and large in volume, they have good diffusion characteristics and can disperse in all directions, providing sufficient pesticide coverage for the crops. In addition, through foaming, pesticides can be saved more effectively. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention. All identical reference numerals in the drawings refer to the same components.

[0020] As Figure 1 shown, a pesticide spraying device includes a bracket, a disc 2 and a rotating nozzle 1. The disc 2 is fixedly connected to the bracket, and a through hole is provided at the center of the disc 2. The rotating nozzle is rotatably connected to the bracket through its top, and a blade 12 is provided at the lower end of the rotating nozzle. The disc is sleeved on the rotating nozzle 3 through the through hole. The disc 2 is horizontally arranged, and there is a gap between the rotating nozzle and the inner wall of the through hole, and they are not connected. Among them, the liquid spraying orifice 13 of the rotating nozzle is located above the disc, and the blade 12 is located below the disc.

[0021] A plurality of small holes 21 are provided on the disc 2, and a spreading rod 14 is horizontally and fixedly arranged on the rotating nozzle 3. The spreading rod 14 is in contact with the upper surface of the disc 2, but not connected.

[0022] The cavity of the rotating nozzle 3 is communicated with the water outlet of the water pump through a water pipe, and the water inlet of the water pump is communicated with the liquid storage barrel. The water pipe is rotationally and sealingly connected to the bottom of the rotating nozzle. The liquid storage barrel stores liquid insecticide.

[0023] In this embodiment, the components of the liquid insecticide include lime sulfur mixture and bubble water. Calculated by mass percentage, 28-degree Baumé lime sulfur mixture: bubble water = 1:39;

[0024] The components of the bubble water include skin care glycerin, single-component α-cyanoacrylate glue, water and household laundry detergent. Calculated by mass percentage, skin care glycerin: single-component α-cyanoacrylate glue: water: household laundry detergent = 1:1:4:4.

[0025] In this embodiment, the method for preparing lime sulfur mixture is to boil lime, sulfur powder, and water in a mass ratio of 1:2:10. The concentration of the lime sulfur mixture prepared in this ratio is generally 20-28 degrees Baume. Before using the lime sulfur mixture, it is necessary to measure the Baume specific gravity (degrees Baume) of the prepared stock solution with a Baume hydrometer, and then dilute it with water to the required concentration. The calculation method for the amount of added water: weight of added water = (stock solution Baume degrees / diluted Baume degrees - 1) × weight of mother liquor. For example, if there are 2 kg of mother liquor with a Baume degree of 20, and it needs to be diluted to a liquid medicine with a Baume degree of 5, the amount of water to be added is: (20 / 5 - 1) × 2 kg = 6 kg.

[0026] When spraying pesticides, add the liquid insecticide into the liquid storage bucket, turn on the water pump, and the water pump transports the liquid insecticide through the water pipe into the cavity of the spray head. Since the liquid spraying port is inclined, when the high-pressure liquid insecticide entering the cavity sprays out from multiple liquid spraying ports, the generated thrust causes the spray head to rotate relative to the bracket. By changing the water pressure of the water pump, the liquid insecticide is sprayed onto the disc, and the spreading rod rotates with the spray head and will spread the liquid falling on the disc evenly into a thin film; the blades rotate with the spray head, generating an upward airflow, and the airflow passes through several small holes on the disc to blow the liquid insecticide film to form bubbles, which disperse around. When the bubbles fall onto the crops, they explode at different positions, and the scattered pesticide liquid gives the crops sufficient pesticide coverage.

[0027] By adding bubble water to the prepared lime sulfur mixture and setting a rotating spray head, a disc, a spreading rod, and blades, the liquid insecticide forms bubbles. Since the bubbles are small in mass and large in volume, they have good diffusion characteristics and can disperse around, giving the crops sufficient pesticide coverage; in addition, through foaming, more pesticides can be saved.

[0028] In this embodiment, the bracket includes a cross beam 3 and a frame suspended on the cross beam. The frame includes a top plate 5 and two vertical plates 6, and is in an inverted U shape as a whole. The top plate 5 is connected to the cross beam 3 through a suspension rod 4. The upper ends of the two vertical plates are connected to the two ends of the top plate, and the lower ends are connected to the disc. The top of the rotating spray head is rotatably connected to the top plate through a bearing.

[0029] In this embodiment, a baffle is fixedly provided on the rotating spray head 3. The baffle is located below the liquid spraying port and above the disc, and the baffle is inclined upward.

[0030] By setting the baffle, after the blades rotate with the rotating spray head, an upward airflow is generated. The wind blowing upward from the gap between the rotating spray head and the inner wall of the through hole changes direction when it encounters the baffle, and part of the wind blows outward in the horizontal direction, giving the bubbles a horizontal initial velocity, making the pesticide bubbles float farther and blowing to all corners of the crops. The pesticide spraying area is increased.

[0031] In this embodiment, the bracket, the disc 2, and the rotary nozzle 3 are all made of plastic products, which are inexpensive and can be reused and replaced after recycling.

[0032] In other embodiments, the bracket, the disc 2, and the rotary nozzle 3 can also be made of stainless steel.

[0033] The foregoing are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
