Description

Technical Field

[0001] The utility model relates to the technical field of pesticide spraying devices, and specifically relates to a pesticide atomizing spraying device. Background Art

[0002] Pest damage is the main reason affecting the yield of fruits and vegetables. Therefore, during the growth process of fruits and vegetables, pesticides need to be used to kill insects.

[0003] Chinese Patent CN202667033U discloses a nozzle for a new type of agricultural spraying mechanism, including a nozzle and a fan. The pesticide is sprayed downward from the nozzle, and the fan is used to increase the speed of the pesticide sprayed downward and bounce it to the back of the leaf after the pesticide touches the ground, so that the crops are evenly treated with the pesticide.

[0004] Due to the relatively thin cuticle on the back of the leaf, pests avoiding natural enemies, and pests fearing light (fear of ultraviolet rays, and it is difficult for insect eggs to hatch under the irradiation of ultraviolet rays), pests generally concentrate on the back of the leaf. However, the pesticide in the above device bounces towards the back of the leaf, and has the following deficiencies: 1. The pesticide is mainly concentrated on the front of the leaf, and the amount of pesticide hitting the back of the leaf is less; 2. The distribution of the pesticide on the back of the leaf is uneven; 3. When the pesticide hits the back of the leaf, it will flow and concentrate on the back of the leaf, resulting in drug spots on the leaf; 4. To make the pesticide bounce, the pesticide must be sprayed in a water column, which will cause great waste. Content of the Utility Model

[0005] To solve the technical problems in the background art, the utility model discloses a pesticide atomizing spraying device.

[0006] The utility model provides a pesticide atomizing spraying device, including a cylinder body and a handle;

[0007] One end of the handle is connected to the cylinder body and forms an angle greater than 60° with the axial direction of the cylinder body; the other end of the handle is for human hand to hold;

[0008] An atomizing nozzle and a fan are arranged inside the cylinder body;

[0009] The atomizing nozzle is used to spray the pesticide in an atomized state;

[0010] The fan is located at the rear side of the atomizing nozzle, and the generated air flow is in the same direction as the spraying direction of the atomizing nozzle;

[0011] The air flow generated by the fan cuts the droplets sprayed by the atomizing nozzle.

[0012] The beneficial effects of the utility model are as follows: 1. Since the stomata on the back of the leaves are large and numerous, spraying pesticides on the back of the leaves is conducive to leaf absorption, and the effect of treating insect pests is more significant; 2. The utility model has a simple structure and is light in weight. Farmers can easily lift it to spray pesticides on fruits and vegetables, so it is also suitable for use by the elderly; 3. When spraying short-stalked fruits and vegetables, it is only necessary to arrange the handle obliquely downward, and the spray direction of the atomizing nozzle can also be arranged obliquely upward, so that farmers can spray pesticides in an upright position, which can reduce labor intensity and improve efficacy; 4. The pesticide is sprayed in an atomized state, and under the action of the fan, the particle size is smaller, and after being attached to the back of the leaves, it will not flow, and will not form a dripping phenomenon, thereby avoiding the formation of drug spots; 5. The pesticide is sprayed from bottom to top, It is evenly distributed on the back of the leaves, with high insecticide efficiency; 6. The pesticide is sprayed in atomized form, covering a wide area, which can save the amount of pesticide covering the back of the leaves, thereby achieving the purpose of saving pesticides; and the pesticide quickly covers the back of the leaves, with high efficiency, which also saves the time of spraying pesticides and further reduces labor intensity; 7. The fan not only increases the kinetic energy of pesticide spraying, but also makes the sprayed pesticide particle size smaller, so that when the pesticide is sprayed and covers the back of the leaves, only a thin layer of water mist that is invisible to the naked eye is formed, which not only has an effective insecticide effect, but also reduces the time for the back of the leaves to dry, reducing the probability of gray mold; 8. The setting of the handle also allows the atomizer nozzle to extend farther and cover a wider range of fruits and vegetables, thereby reducing the length of the farmer's walking path when spraying pesticides.

[0013] In order to improve the spraying intensity of pesticides, the further design is: the atomizing nozzle includes a base and a cover connected by threads; the liquid outlet of the base is inserted into the cover; the base and the cover form a spiral channel, so that the pesticide is sprayed out in a spiral shape. Its specific structure is: the cover and the outside of the liquid outlet of the base form a first liquid cavity; the end of the liquid outlet of the base is provided with a concave platform, and the concave platform and the cover form a second liquid cavity; the bottom of the cover is provided with a spray hole, connecting the second liquid cavity with the outside; the side wall of the concave platform is provided with a guide groove, connecting the first liquid cavity and the second liquid cavity; the extension direction of the guide groove is staggered with the spray hole.

[0014] In order to extend the spiral path of the channel and further improve the spraying intensity of the pesticide, specifically: a liquid outlet hole connected to the first liquid cavity is provided on the base; the guide groove is close to the liquid outlet hole and is staggered with the liquid outlet hole in the axial and radial directions of the cover.

[0015] Since pesticides are easily sprayed away from the liquid outlet of the base, resulting in pesticide waste, a further improvement is that a sealing ring is connected between the base and the cover; the sealing ring is located on one side of the liquid outlet and away from the guide groove.

[0016] To simplify the structure of the present utility model and facilitate the inflow of pesticides into the liquid inlet pipe, a further design is as follows: an outlet pipe is arranged inside the cylinder body; atomizing nozzles are evenly distributed on one side of the outlet pipe.

[0017] To facilitate the disassembly and assembly of the liquid inlet pipe and the outlet pipe, a further design is as follows: the outlet pipe is provided with a notch, and a joint is connected at the notch; the liquid inlet pipe is inserted into the handle and is threadedly connected to the joint.

[0018] To facilitate the operation of farmers, a further design is as follows: a power button is arranged on the handle; the power button is located near the other end of the handle, and its specific position is configured such that when a person holds the handle, the thumb can extend to press the power button.

[0019] To prevent the fan from being damaged by external forces and also prevent a person's hand from reaching into the cylinder body and being cut by the fan blades in case of misoperation, a further design is as follows: a bottom cover is arranged at the other end of the cylinder body, facing away from the spraying direction of the atomizing nozzles.

[0020] The setting of the bottom cover will result in insufficient air intake of the fan. Based on this, a further improvement lies in that: a plurality of air intake holes are arranged on both the bottom cover and the side part of the cylinder body at the air intake position of the fan.

Specific embodiments

[0030] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0031] As Figure 1 shown, the present utility model discloses a pesticide atomizing spraying device, including a cylinder body 1 and a handle 2. The handle 2 is a section of square pipe, one end of which is fixedly connected to the outer wall of the cylinder body 1 by welding, and forms an angle greater than 60° with the axis of the cylinder body 1. In this embodiment, the angle is 90°. The other end of the handle 2 is for human hand to hold, and the setting of the square pipe facilitates the human hand to hold and fix it, and its position is more stable and not easy to rotate.

[0032] A liquid inlet pipe 7 is inserted into the handle 2, and both ends of it are connected to the handle 2 through a support plate and fixed by welding. The inner end of the liquid inlet pipe 7 is connected with an annular liquid outlet pipe 5. The liquid outlet pipe 5 opens to one side of the handle 2 and is connected with a joint 6. This joint 6 is provided with two symmetrically arranged outlets, which are respectively connected to both ends of the opening of the liquid outlet pipe 5, and is also provided with an inlet facing the handle 2. This inlet is provided with internal threads and is threadedly connected to the inner end of the liquid inlet pipe 7, so as to realize the detachable connection between the liquid inlet pipe 7 and the liquid outlet pipe 5.

[0033] A power button 9 is arranged on the handle 2; the power button 9 is close to the other end of the handle 2, and its specific position is configured such that when a human hand holds the handle 2, the thumb can extend to press the power button 9, so as to facilitate the operation of farmers. The power button 9 is electrically connected to the fan 4 through an electric wire, and is also electrically connected to a water pump (the water pump is used to transport pesticides, and its transport pressure is 1 - 4 kg, adjusted according to the height of the leaves) through an electric wire. The voltage of its power supply is 12V, which is used to control the opening and closing of the fan and the water pump simultaneously.

[0034] A liquid outlet pipe 5 and a fan 4 are installed in the cylinder 1. The liquid outlet pipe 5 is close to one end of the cylinder 1, and this end is set as the liquid outlet end of the cylinder 1. One or more liquid outlet holes 38 are set on the side of the liquid outlet pipe 5 facing the liquid outlet end. In this embodiment, the number of liquid outlet holes 38 is three symmetrically arranged, and in other embodiments, the number of liquid outlet holes 38 can be set to one or more than one. An atomizing nozzle 3 is installed on each liquid outlet hole 38. The atomizing nozzle 3 includes a base 31 and a cover 32. The bottom of the base 31 is fixed to the liquid outlet pipe 5 by welding, and the cover 32 is sleeved from the top to the bottom of the base 31 and fixed to the base 31 by a threaded connection. Figures 3 - 5 As shown, the base 31 is provided with a blind hole with an open end at the bottom, and the top of the base 31 abuts against the bottom of the cover 32, so that the cover 32 and the outside of the liquid outlet end of the base 31 form a first liquid chamber 33; the end of the liquid outlet end of the base 31 is provided with a recessed concave platform 34, and the concave platform 34 and the cover 32 form a second liquid chamber 35; the bottom of the cover 32 is provided with a spray hole 36, which connects the second liquid chamber 35 with the outside; the side wall of the concave platform 34 is provided with a guide groove 37, which connects the first liquid chamber 33 and the second liquid chamber 35; the extension direction of the guide groove 37 is staggered with the spray hole 36.

[0035] The base 31 is provided with a liquid outlet 38 connected to the first liquid chamber 33; the guide groove 37 is close to the liquid outlet 38 and is staggered with the liquid outlet 38 in the axial direction and radial direction of the cover 32. A sealing ring 39 is also connected between the base 31 and the cover 32; the sealing ring 39 is located on one side of the liquid outlet 38 and away from the guide groove 37. The sealing ring 39 can prevent the pesticide from being sprayed away from the liquid outlet end of the base 31, thereby causing waste of pesticide.

[0036] In this arrangement, the pesticide enters from the outer end of the liquid inlet pipe 7, then enters the liquid outlet pipe 5, and then passes through the blind hole, the liquid outlet hole 38, the first liquid chamber 33, the guide groove 37 and the second liquid chamber 35 in sequence, and finally sprays out in the form of mist from the spray hole 36. The liquid outlet hole 38, the first liquid chamber 33, the guide groove 37 and the second liquid chamber 35 form a spiral channel, which can improve the spraying intensity of the pesticide.

[0037] The fan 4 is located at the rear side of the atomizing nozzle 3, and the airflow generated is consistent with the spraying direction of the atomizing nozzle 3, providing power to the sprayed pesticide and improving the spraying intensity and distance of the pesticide; the airflow generated by the fan 4 can also cut the droplets sprayed by the atomizing nozzle 3, making the sprayed pesticide particle size smaller.

[0038] The barrel 1 is provided with a mounting hole 11, and the automatic screw passes through the mounting hole 11 and is threadedly connected to the outer shell of the fan 4, so that the fan 4 can be installed and fixed. At the same time, by changing the connection position of the automatic screw and the fan 4, the installation position of the fan 4 can be changed, thereby changing the distance between the fan 4 and the liquid outlet pipe 5, changing the power provided by the fan 4 to the pesticide, and adjusting the spraying intensity and distance of the pesticide.

[0039] As shown Figure 2 in the figure, the other end of the cylinder body 1 is connected with a bottom cover 8, which is used to prevent a person's hand from reaching into the cylinder body 1 and being cut by the blades of the fan 4 or getting an electric shock in case of misoperation. A plurality of air inlet holes 81 are arranged at the bottom cover 8 and the side part of the cylinder body 1 at the air inlet position of the fan 4 to meet the air inlet volume requirement of the fan 4.

[0040] The beneficial effects of the utility model are as follows: 1. Since the stomata on the back of the leaf are large and numerous, spraying pesticides on the back of the leaf is beneficial to the absorption of the leaf and the treatment effect of pests is more remarkable; 2. The structure of the utility model is simple and the weight is light, so that farmers can easily lift it to spray pesticides on fruits and vegetables (refer to Figure 6 ), so it is also suitable for the elderly to use; 3. When spraying short-stem fruits and vegetables, as Figure 7 shown in the figure, only by arranging the handle 2 obliquely downward, the spraying direction of the atomizing nozzle can also be arranged obliquely upward, so that farmers can spray pesticides in an upright position. Moreover, the connection position of the handle 2 and the cylinder body 1 is above the center of gravity of the cylinder body 1. When the handle 2 is obliquely downward, the liquid outlet end of the cylinder body 1 will automatically be arranged obliquely upward under the action of gravity, without deliberately controlling the position of the cylinder body 1, so as to achieve the purpose of saving labor, reducing labor intensity and improving work efficiency; 4. The pesticide is atomized and ejected, and under the action of the fan 4, the particle size is smaller. After adhering to the back of the leaf, it will not flow and will not form a dripping phenomenon, thus avoiding the generation of drug spots; 5. The pesticide is ejected from bottom to top and is evenly distributed on the back of the leaf, with high insect killing efficiency; 6. The pesticide is atomized and ejected, with a wide coverage area, which can save the amount of pesticide covering the back of the leaf, so as to achieve the purpose of saving pesticides; moreover, the pesticide quickly covers the back of the leaf, with high efficiency, and also saves the time for spraying pesticides, further reducing the labor intensity; 7. The fan not only improves the kinetic energy during pesticide spraying, but also makes the particle size of the sprayed pesticide smaller, so that when the pesticide is sprayed and covered on the back of the leaf, only a thin water mist layer invisible to the naked eye will be formed, which not only has an effective insect killing effect, but also reduces the dry time on the back of the leaf and reduces the occurrence probability of gray mold; 8. The setting of the handle 2 also makes the atomizing nozzle 3 extend farther, covering a wider range of fruits and vegetables, thus reducing the walking path length of farmers when spraying pesticides.

[0041] The utility model is used for spraying pesticides on strawberries, and the effect is better. When spraying pesticides, as Figure 7 shown in the figure, the atomizing nozzle 3 can be easily placed under the strawberry leaves to spray pesticides on the back of the leaves. It is not only convenient to operate, the pesticides are evenly sprayed, and the amount of pesticide used can be saved by half, but also the back of the leaves can reach a dry effect after 15 minutes.

[0042] Based on the above-mentioned ideal embodiments of the present utility model as inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
