However, the rice transplanter or the seeder often has inaccurate spraying phenomenon when spraying the pesticide, which causes various problems such as seedling insect pest or pesticide injury, waste of pesticide liquid, soil pollution and the like.
In view of this, some embodiments of the present disclosure provide a detachable pesticide spraying device capable of detecting a rotation speed of a working transmission shaft and controlling a pumping amount of a pesticide solution according to the detected rotation speed, thereby improving accuracy and uniformity of pesticide application, and thus solving various problems of seedling insect pests or phytotoxicity, pesticide waste, soil pollution, etc.
Fig. 1 is a schematic block diagram of a detachable pesticide spraying device according to some embodiments of the present disclosure.
In some embodiments of the present description a detachable pesticide spraying device 1 is provided. The detachable pesticide spraying device 1 is used for agricultural machinery, is detachably connected with the agricultural machinery, and is convenient to match with different agricultural machinery. In some embodiments, the detachable pesticide spraying device 1 includes at least a pesticide tank assembly 10, a spray assembly 20, a detection assembly 30, and a control assembly 40.
In some embodiments, the medical kit assembly 10 includes a liquid delivery pump 11, a housing 12, a liquid delivery conduit 13, and a battery 14. In some embodiments, the tank 12 is used for storing liquid medicine, the liquid outlet of the tank 12 is connected to the liquid inlet of the liquid feeding pump 11, the liquid outlet of the liquid feeding pump 11 is connected to the liquid feeding pipe 13, and the battery 14 is used for providing electric energy to the liquid feeding pump 11. When the liquid-feeding pump 11 works, the liquid medicine in the box 12 enters the liquid-feeding pipeline 13 under the action of the liquid-feeding pump 11.
In some embodiments, the spray assembly 20 communicates with the liquid delivery conduit 13 for spraying the liquid drug. When the liquid feeding pump 11 works, the liquid medicine in the box body 12 is sprayed outwards by the spraying component 20 after passing through the liquid feeding pipeline 13, and the pesticide is applied to crops (such as seedlings) to reduce insect damage.
In some embodiments, the detection assembly 30 is configured to be removably connectable with the work drive shaft 2 of an agricultural machine and to detect the rotational speed of the work drive shaft 2 when connected with the work drive shaft 2. In some embodiments, the work drive shaft 2 of the agricultural machine refers to a drive shaft in a mechanism of the agricultural machine for performing a work. Taking a rice transplanter as an example, the operation transmission shaft 2 of the rice transplanter refers to a transmission shaft in a rice transplanting mechanism, and the rotation speed of the transmission shaft can represent the transplanting speed of the rice transplanting mechanism so as to determine the transplanting quantity of the rice transplanter.
In some embodiments, the control assembly 40 includes a main controller 41 and a frequency converter 42, the main controller 41 being configured to control the frequency converter 42 to adjust the pumping capacity of the liquid feed pump 11 based on the detected rotational speed. In some embodiments, the frequency converter 42 is electrically connected to the main controller 41 and the liquid feed pump 11. In some embodiments, the greater the rotational speed of the work drive shaft 2 of the farm machine, which means that the faster the work is performed, the greater the frequency of the frequency converter 42 is controlled by the main controller 41, thereby increasing the pumping capacity of the liquid feed pump 11. In some embodiments, the smaller the rotational speed of the work drive shaft 2 of the farm machine, which means that the slower the work speed is performed, the frequency of the frequency converter 42 is controlled by the main controller 41 to decrease, thereby decreasing the pumping capacity of the liquid feed pump 11.
According to the detachable pesticide spraying device 1 of some of the above embodiments, the detecting assembly 30 detects the rotation speed of the operation drive shaft 2 of the agricultural machine, and can more accurately acquire the actual operation amount of the agricultural machine, such as the transplanting amount, the sowing amount, and the like. The control component 40 controls the frequency converter 42 according to the detected rotation speed to adjust the pumping quantity of the liquid-feeding pump 11, namely, adjusts the pumping quantity of the liquid-feeding pump 11 according to the actual working quantity of the agricultural machinery, so that crops can be properly sprayed with the liquid medicine, insect damage caused by too little liquid medicine is avoided, and phytotoxicity caused by too much liquid medicine is also avoided.
Compared with the scheme of spraying according to the travelling speed of the agricultural machine, when the detachable pesticide spraying device 1 sprays according to the travelling speed of the agricultural machine, the agricultural machine can spray when the agricultural machine singly runs and the operating mechanism is not started, for example, the operating mechanism does not operate when the agricultural machine turns, and at the moment, the agricultural machine has the travelling speed, the pesticide spraying can be performed, so that the waste of the pesticide liquid is caused. However, the detachable pesticide spraying device 1 according to some embodiments of the present disclosure can improve the accuracy and uniformity of pesticide application by detecting the rotation speed of the operation transmission shaft 2 and spraying the pesticide according to the actual operation amount of the operation transmission shaft 2, thereby solving various problems such as seedling insect pest or phytotoxicity, waste of pesticide liquid, soil pollution, etc.
Fig. 2 is a schematic illustration of a spray assembly 20 according to some embodiments of the present disclosure.
In some embodiments, jetting assembly 20 includes one or more. Wherein multiple spray assemblies 20 can increase spray coverage and improve efficiency of application. In some embodiments, the spray apertures of at least one spray assembly 20 of the spray assemblies 20 are variable. In some embodiments, the spray aperture of the spray assembly 20 is determined according to the pumping capacity of the liquid delivery pump 11, and the dosage is adjusted by the variation of the spray aperture.
In some embodiments, at least one jetting assembly 20 of jetting assemblies 20 includes a control valve 21 and a plurality of jets 22, the plurality of jets 22 having different apertures. In some embodiments, spray assembly 20 includes, but is not limited to, two, three, four, five spray heads 22. In some embodiments, at least two spray heads 22 of the plurality of spray heads 22 have the same aperture and additional spray heads 22 have different apertures. In some embodiments, the aperture of each spray head 22 of the plurality of spray heads 22 is the same.
In some embodiments, the control valve 21 is configured to control the plurality of spray heads 22 to be in communication with or closed off the liquid delivery conduit 13 based on the rotational speed. In some embodiments, the control valve 21 selects the corresponding spray head 22 to be turned on or off from the liquid delivery pipe 13 based on the pumping amount of the liquid delivery pump 11 to adjust the spray aperture to control the application amount. Wherein communication between the nozzle 22 and the liquid feed pipe 13 means that liquid can flow from the liquid feed pipe 13 to the nozzle 22, and closing of the nozzle 22 and the liquid feed pipe 13 means that liquid cannot flow from the liquid feed pipe 13 to the nozzle 22. Illustratively, the pumping capacity of the liquid sending pump 11 includes a first threshold interval, a second threshold interval, and a third threshold interval that sequentially increase, and the spray assembly 20 includes a first spray head 221, a second spray head 222, and a third spray head 223 that sequentially increase in aperture. When the pumping amount of the liquid feeding pump 11 is within the first threshold interval, the control valve 21 controls the first nozzle 221 to be communicated with the liquid feeding pipeline 13, and simultaneously controls the second nozzle 222 and the third nozzle 223 to be respectively closed with the liquid feeding pipeline 13. When the pumping amount of the liquid feeding pump 11 is within the second threshold interval, the control valve 21 controls the second nozzle 222 to be communicated with the liquid feeding pipe 13, and simultaneously controls the first nozzle 221 and the third nozzle 223 to be respectively closed with the liquid feeding pipe 13. When the pumping amount of the liquid feeding pump 11 is within the third threshold interval, the control valve 21 controls the third nozzle 223 to be communicated with the liquid feeding pipe 13, and simultaneously controls the first nozzle 221 and the second nozzle 222 to be respectively closed with the liquid feeding pipe 13.
In some embodiments, the control valve 21 controls at least two of the plurality of spray heads 22 to be in communication with the liquid delivery conduit 13, and the remaining spray heads 22 to be closed with the liquid delivery conduit 13. For example, when the pumping amount of the liquid feeding pump 11 is greater than the third threshold interval, the control valve 21 controls the second nozzle 222 and the third nozzle 223 to be in communication with the liquid feeding pipe 13, and simultaneously controls the first nozzle 221 to be closed with the liquid feeding pipe 13.
According to the above embodiment, the spraying assembly 20 includes a plurality of spraying heads 22 with different apertures, and the control valve 21 selects the spraying heads 22 with corresponding apertures according to the pumping amount of the liquid feeding pump 11, so as to avoid too much or too little spraying of the liquid medicine, thereby more precisely controlling the spraying amount of the liquid medicine.
Fig. 3 is a schematic illustration of a spray assembly 20 according to some embodiments of the present disclosure.
In some embodiments, spray assembly 20, when coupled to an agricultural machine, may have spray heads 22 of different apertures with different spray directions, including: the spray angle of spray head 22 is positively correlated to the aperture of spray head 22. The spray angle of the spray head 22 refers to an angle between the spray direction of the spray head 22 and the vertical direction. In some embodiments, spray assembly 20 includes first spray head 221, second spray head 222, and third spray head 223 with sequentially increasing apertures, with the spray angles of the three spray heads 22 being different. Illustratively, the first nozzle 221 has an angle of ejection α, the second nozzle 222 has an angle of ejection β, and the third nozzle 223 has an angle of ejection γ. The spray angle of spray head 22 is positively correlated with the aperture of spray head 22 including: the aperture of the first nozzle 221 is smaller than the aperture of the second nozzle 222, the aperture of the second nozzle 222 is smaller than the aperture of the third nozzle 223, and the spray angle α of the first nozzle 221 is smaller than the spray angle β of the second nozzle 222, and the spray angle β of the second nozzle 222 is smaller than the spray angle γ of the third nozzle 223. The larger the pumping amount of the liquid feeding pump 11 is, the larger the aperture of the used spray head 22 is, so that the hydraulic pressure in the spray head 22 is higher, the larger the spray angle of the spray head 22 with the larger aperture is set to be larger, which is beneficial to increasing the coverage range of the liquid medicine, and the smaller the spray angle of the spray head 22 with the smaller aperture is set to be smaller, which is beneficial to the directional spraying of local seedlings.
In some embodiments, the spray angles of the plurality of spray heads 22 of spray assembly 20 are the same.
In some embodiments, the jetting assembly 20 further includes a plastically deformable hose 224, one end of the plastically deformable hose 224 being connected to the control valve 21 and the other end being connected to the spray head 22. The plastic deformable hose 224 can maintain the deformed shape after being deformed by an external force, and the spray direction of the spray head 22 can be adjusted according to the desired spray range, thereby improving the spray accuracy.

In some embodiments, the straight section 225 and the tightening section 226 are integrally formed.
In some embodiments, the tightening segment 226 includes a housing 2261, a plurality of flaps 2262, an elastic layer 2263, and first and second attachment films 2264.
In some embodiments, a plurality of the fan blades 2262 are circumferentially distributed along the inner wall of the tightening segment 226 and are respectively deflectable connected to the inner wall of the straight segment 225. In some embodiments, the panel 2262 is coupled to the straight section 225 by a hinge structure such as a ball joint, a pivot, or the like. For example, an end of the plurality of fan plates 2262 remote from the injection ports 227 is deflectable connected to the end of the straight section 225 to enable the fan plates 2262 to deflect radially relative to the inner wall of the tightening section 226.
In some embodiments, adjacent fan blades 2262 are connected by a first connecting membrane (not shown). In some embodiments, the first connection film is made of a flexible material, such as fabric, plastic, or the like. In some embodiments, the first attachment film has a waterproof effect, for example, the first attachment film is made of waterproof cloth to prevent the elastic layer 2263 from being wetted. The first attachment membrane expands when the fan plate 2262 is deflected in a direction toward the housing 2261 proximate the tightening segment 226 and collapses when the fan plate 2262 is deflected in a direction away from the housing 2261 proximate the tightening segment 226.
In some embodiments, the ends of the plurality of fan plates 2262 are each connected to one end of the second connection film 2264, and the other end of the second connection film 2264 is connected to the ejection port 227. In some embodiments, second attachment membrane 2264 is made of an elastic material, such as rubber, silicone, or the like. In some embodiments, the second attachment film 2264 has a waterproof effect to prevent the elastic layer 2263 from wetting. In some embodiments, second attachment membrane 2264 is in a stretched state in the initial state, which is advantageous for maintaining the regularity of the spout shape. The initial state refers to a state in which the head 22 is not hydraulically pressurized.
In some embodiments, second attachment membrane 2264 may also be made of a flexible material, such as fabric, plastic, or the like.
In some embodiments, the elastic layer 2263 is disposed between the fan plate 2262 and the housing 2261. In some embodiments, the elastic layer 2263 maintains the second connection film 2264 in a stretched state in an initial state. The ratio of the elastic coefficient of the elastic layer 2263 to the elastic coefficient of the second connection film 2264 is not less than 5:1, so that the elastic layer 2263 is prevented from being greatly deformed by the second connection film 2264 pulling the fan plate 2262.
In some embodiments, the elastic layer 2263 comprises a sponge rubber, and the 25% compression stiffness of the elastic layer 2263 is not less than 2Kpa, wherein the 25% compression stiffness of the elastic layer 2263 refers to the pressure required by the elastic layer 2263 to generate 25% compression deformation. In some embodiments, the 50% compression stiffness of the elastic layer 2263 is not less than 1MPa, where the 50% compression stiffness of the elastic layer 2263 refers to the pressure required to generate 50% compression deformation of the elastic layer 2263.
According to the ejection head 22 in some of the embodiments described above, in an initial state in which the ejection head 22 is not hydraulically pressurized, the elastic layer 2263 is in an initial shape. When the liquid is ejected from the head 22, the fan plate 2262 is deflected in the direction of the housing 2261 near the tightening segment 226, and the compressed elastic layer 2263 is deformed, the first connection membrane is expanded, the second connection membrane 2264 is contracted, and the aperture of the ejection port 227 is increased. In some embodiments, the fan plate 2262 deflects as a function of the hydraulic pressure within the spray head 22. For example, when the hydraulic pressure in the head 22 increases, the hydraulic drive fan 2262 deflects in the direction of the housing 2261 near the tightening segment 226, and the compression elastic layer 2263 deforms, thereby increasing the aperture of the injection port 227. For another example, when the hydraulic pressure in the head 22 becomes smaller, the elastic layer 2263 drives the fan 2262 to deflect away from the housing 2261 of the tightening segment 226 by the elastic restoring force, so that the aperture of the ejection port 227 becomes smaller. Thereby realizing the purpose of changing the spray aperture of the spray head 22, being convenient for changing the aperture of the spray head 22 according to the follow-up of different pumping quantities of the liquid feeding pump 11 and improving the spray accuracy.
