Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a drug spraying device for preventing and controlling corn plant diseases and insect pests. Background Art

[0002] Corn is an annual herbaceous plant of the genus Zea in the Poaceae family. It is an important food crop and feed crop, and also the crop with the highest total output in the world. It is rich in protein, fat, vitamins, trace elements, cellulose, etc., and has great potential for developing high-nutrition and high-biological-functional foods. After planting, corn needs to be sprayed with pesticides using a pesticide sprayer according to its growth conditions to achieve the purpose of preventing and controlling pests.

[0003] Most existing pesticide sprayers only have a single spray boom, which requires workers to hold the boom while walking and spraying the corn stalks up and down, which is physically demanding, has a small spraying range, and low work efficiency.

[0004] An existing patent (publication number: CN219125189U) discloses a pesticide sprayer device. When this utility model is used, after the pesticide and water are placed in the water tank respectively, they can be automatically stirred and mixed through the stirring component. The angle of the nozzle can be adjusted according to the needs of use by bending and adjusting the metal hose. The setting of multiple water distribution pipes makes the pesticide spraying range wider, and the pesticide can be sprayed on the entire corn stalk plant, reducing the repetitiveness of spraying drugs. The combined use of several devices greatly saves personnel physical strength, and the spraying range is wider, effectively improving the spraying efficiency.

[0005] In response to the above problems, existing patents have provided solutions. However, during actual spraying operations, the above patents are unable to monitor the liquid level inside the water tank in real time. When the liquid level is too low, the user cannot be reminded, resulting in the user being unable to promptly know that there is insufficient medicine in the water tank, thereby affecting the operation efficiency. In addition, when the liquid level is too low, the water pump cannot be automatically controlled to stop running, so that the water pump will continue to work and suck air, which can easily cause damage to the water pump and increase the equipment maintenance cost and usage risk.

[0006] For this reason, a drug spraying device for preventing and controlling corn plantation diseases and insect pests is proposed. Utility Model Content

[0007] The purpose of the utility model is to provide a drug spraying device for controlling corn plant diseases and insect pests, which can solve the problem that in the above-mentioned patent, during actual spraying operations, the liquid level inside the water tank cannot be monitored in real time.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-6 , this utility model provides a technical solution:

[0029] A drug spraying device for controlling pests and diseases in corn planting includes a water tank 1, a shoulder strap 2 is provided on the rear side of the water tank 1, a controller 3 is provided on the right side of the water tank 1, a partition 4 is fixedly connected to the bottom side of the water tank 1, a material pipe 5 is connected to the left side of the top of the water tank 1, a stirring structure 6 is provided inside the water tank 1, an automatic control mechanism 7 is provided on the left side of the water tank 1, a lifting assembly 8 is provided on the front side of the water tank 1, and a spraying structure 9 is provided on the front side of the lifting assembly 8;

[0030] The automatic control mechanism 7 includes a water pump 701 bolted to the bottom side of the water tank 1, the absorption end of the water pump 701 is connected to the bottom of the partition 4, the output end of the water pump 701 is connected to the spraying structure 9, the left side of the water tank 1 is bolted to a central controller 702, the left side of the water tank 1 is bolted to a liquid level sensor 703, the sensing end of the liquid level sensor 703 is located on the left side of the water tank 1, and an alarm 704 is provided on the top of the water tank 1, and the alarm 704 is electrically connected to the central controller 702.

[0031] In this embodiment: the liquid level height inside the water tank 1 is monitored in real time by the liquid level sensor 703, and the liquid level information is converted into an electrical signal and transmitted to the central controller 702. When the liquid level in the water tank 1 is higher than the preset normal working liquid level, the equipment is operating normally. The user can start the stirring structure 6 through the controller 3 to fully stir and mix the pesticide and water added to the water tank 1 through the material pipe 5 to ensure that the concentration of the sprayed pesticide is uniform. When pesticide spraying is required, the user operates the controller 3 to start the water pump 701. The water pump 701 extracts the evenly mixed pesticide solution from the bottom of the partition 4 and transports it to the spraying structure 9. At this time, the user can adjust the height of the spraying structure 9 through the lifting component 8 according to the actual height of the corn plant, so that the atomizing nozzle 904 is at a uniform level. At the most suitable spraying position to ensure that the pesticide can accurately and comprehensively cover the corn plants, with the continuous spraying of pesticides, the liquid level in the water tank 1 gradually decreases. When the liquid level sensor 703 detects that the liquid level has dropped to a level close to the dangerous level, the liquid level sensor 703 immediately sends a signal to the central controller 702. After receiving the signal, the central controller 702 quickly controls the alarm 704 to sound an alarm to remind the user that the pesticide in the water tank 1 is about to run out and needs to be replenished in time. On the other hand, the central controller 702 simultaneously sends a stop working instruction to the water pump 701, so that the water pump 701 stops running immediately, thereby effectively preventing the water pump 701 from sucking in air due to too low a liquid level, avoiding damage to the water pump 701, ensuring the normal service life of the equipment, and reducing the equipment maintenance cost.

[0032] Specifically, such as Figure 5 As shown, the lifting assembly 8 includes a second motor 801 bolted to the front side of the water tank 1 , and the second motor 801 is electrically connected to the controller 3 .

[0033] Specifically, such as Figure 5 As shown, the output end of the second motor 801 is bolted with a threaded rod 802 , the outer side of the threaded rod 802 is threadedly connected to a lifting block 803 , and the front side of the lifting block 803 is bolted to the spraying structure 9 .

[0034] Specifically, such as Figure 5 As shown, the bottom of the threaded rod 802 is bolted to a limit block 804 , and the limit block 804 is located at the bottom of the lifting block 803 .

[0035] In this embodiment: when the second motor 801 is started by the controller 3, its output end drives the threaded rod 802 to rotate. Since the lifting block 803 is threadedly connected to the threaded rod 802, during the rotation of the threaded rod 802, the lifting block 803 will move up and down along the threaded rod 802, thereby driving the spraying structure 9 bolted thereto to achieve height adjustment, so as to adapt to the height differences of corn plants at different growth stages. Whether it is a short seedling or a tall adult plant, it can ensure that the spraying structure 9 is at the optimal spraying height, so that pesticides can accurately cover various parts of the corn plant, improve the pest control effect, and avoid pesticide waste. In addition, the limit block 804 bolted to the bottom of the threaded rod 802 is located at the bottom of the lifting block 803. Its main function is to prevent the lifting block 803 from detaching from the threaded rod 802 during the downward movement.

[0036] Specifically, such as Figure 4 As shown, the stirring structure 6 includes a first motor 601 bolted to the top of the water tank 1 , an output end of the first motor 601 passes through the top of the water tank 1 , and the first motor 601 is electrically connected to the controller 3 .

[0037] Specifically, such as Figure 4 As shown, the output end of the first motor 601 is bolted with a shaft 602 , and the bottom of the shaft 602 is fixedly connected with a spiral blade 603 .

[0038] In this embodiment: the first motor 601 is started by the controller 3. After the first motor 601 is started, its output end drives the shaft 602 to rotate, and the spiral blade 603 at the bottom of the shaft 602 rotates accordingly. After pesticide and water are added to the water tank 1, the rotation of the spiral blade 603 can generate a strong stirring force, so that the pesticide and water are quickly mixed evenly, ensuring that the concentration of the pesticide sprayed from the spraying structure 9 is consistent. This efficient and uniform stirring method improves the use effect of the pesticide, ensures the effectiveness of corn disease and insect pest control, and reduces the situation where the control effect is poor due to uneven pesticide concentration.

[0039] Specifically, such as Figure 6 As shown, the spraying structure 9 includes a hose 901 arranged on the left side of the water tank 1. The right side of the hose 901 passes through the left side of the water tank 1 and is connected to the output end of the water pump 701. The front side of the lifting block 803 is bolted with a spray barrel 902, and the top of the spray barrel 902 is connected to the bottom of the soft tube.

[0040] Specifically, such as Figure 6 As shown, both sides of the spray barrel 902 are connected to the spray pipe 903 , and the outer side of the spray pipe 903 is connected to the atomizing nozzle 904 .

[0041] In this embodiment, the pesticide solution in the water tank 1 is pumped out by the water pump 701 and transported to the spray barrel 902 through the hose 901. The solution is then distributed to each atomizing nozzle 904 by the nozzles 903 connected on both sides of the spray barrel 902. The design of the multiple atomizing nozzles 904 enables the pesticide to be sprayed evenly in the form of mist to form a large coverage area, ensuring that the corn plants can receive the pesticide from all directions. This wide and uniform spraying method can effectively improve the comprehensiveness of pest control, reduce the omission of pests and diseases, improve the control effect, and help protect the healthy growth of corn plants. At the same time, the spray barrel 902 is bolted to the lifting block 803. During the process of adjusting the spraying height, when the lifting block 803 drives the spray barrel 902 to rise or fall, the spraying angle and range of the atomizing nozzle 904 can be adaptively adjusted with the height change, ensuring that the best pesticide coverage effect can be achieved at different heights. The coordinated work of the two further improves the adaptability of the equipment to corn plants of different heights and enhances the practicality and flexibility of the equipment.

[0042] Working principle: When using the corn planting pest control drug spraying equipment, first, the user carries the device on his back through the strap 2, stands next to the corn field and prepares to work, adds an appropriate amount of pesticide and water into the water tank 1 through the material pipe 5, and then uses the controller 3 to start the first motor 601. The first motor 601 drives the shaft 602 to rotate, and the spiral blade 603 at the bottom of the shaft 602 rotates accordingly, quickly and fully stirring and mixing the pesticide and water in the water tank 1 to ensure that the concentration of the pesticide solution is uniform. Then, the user adjusts the height of the corn plant according to its current growth height. , the controller 3 controls the second motor 801 to start, the threaded rod 802 at the output end of the second motor 801 starts to rotate, and the lifting block 803 threadedly connected to the threaded rod 802 will move up and down along the threaded rod 802, thereby driving the spraying structure 9 bolted thereto to adjust to a suitable height position, so that the atomizing nozzle 904 is aimed at the target spraying area of ​​the corn plants. After that, the user operates the controller 3 again to start the water pump 701 in the automatic control mechanism 7. The water pump 701 extracts the mixed pesticide solution from the area separated by the partition 4 on the bottom side of the water tank 1. The pesticide solution passes through the soft The liquid is transported to the spray barrel 902 through the pipe 901, and then distributed to each atomizing nozzle 904 through the nozzles 903 on both sides of the spray barrel 902. Under the pressure of the water pump 701, the pesticide is evenly sprayed out from the atomizing nozzle 904 in the form of mist, covering the corn plants to prevent and control pests and diseases. During the entire spraying process, the liquid level sensor 703 monitors the liquid level in the water tank 1 in real time. When the liquid level sensor 703 detects that the liquid level drops to a dangerous level, it immediately transmits a signal to the central controller 702. After receiving the signal, the central controller 702 quickly controls the alarm. Device 704 sounds an alarm to remind the user that the pesticide in water tank 1 is about to run out and needs to be replenished in time. On the other hand, the central controller 702 simultaneously sends a stop work instruction to the water pump 701 to stop the water pump 701 from running to prevent the water pump 701 from sucking in air due to the low liquid level and damaging the equipment. When replenishing pesticides and water, the user only needs to repeat the above-mentioned feeding and operation steps to continue the drug spraying operation for corn planting pest control, ensuring the efficiency, accuracy and safety of the entire operation process, effectively improving the pest control effect, and ensuring the healthy growth and high yield of corn.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
