Description

Technical Field

[0001] The invention relates to the technical field of sprayers, and in particular to a fast-response triple atomizing air-conveying centrifugal spray head. Background Art

[0002] At present, according to the development requirements of precision agriculture and smart agriculture, spray technology needs to be more efficient and accurate. With the development of spray technology and pest detection technology, targeted spot spraying technology has begun to attract more and more attention. Spraying is one of the important links in the pesticide application process, and the spray nozzle is also an important part of the pesticide application machinery. Therefore, the realization of targeted spot spraying technology is inseparable from the innovation of spray nozzles. However, the current spray technology still has problems such as droplet drift, poor atomization effect and slow spray response.

[0003] At present, the existing technologies are mainly based on simple single-shot atomizing nozzles, which have poor atomization effects, and the liquid medicine cannot adhere well to the crops, resulting in low liquid medicine utilization. In addition, the spray mist from the current nozzles will produce droplet drift after being affected by external wind, and the liquid medicine cannot be accurately sprayed to the pest area. Some large sprayers are equipped with wind curtain systems to reduce droplet drift, but the wind curtain system has high power consumption and large size, and is only suitable for large sprayers. The current variable nozzles have problems such as high delay and large pressure fluctuations when opening and closing valves, and cannot meet the requirements of point spraying technology in higher-level precision agriculture. Summary of the invention

[0004] The object of the present invention is to provide a fast-response triple atomizing air-conveying centrifugal nozzle to solve the technical problems of poor liquid medicine spraying accuracy and high nozzle opening and closing delay in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions: The invention provides a fast-response triple atomizing air-conveying centrifugal nozzle, comprising: A housing component, the housing component comprising an inlet joint and a return joint, wherein the output ends of the inlet joint and the return joint are respectively connected to an inlet flow channel and a return flow channel; A transmission assembly, the transmission assembly comprising a central transmission shaft, a plurality of auxiliary transmission shafts, a central gear connected to the central transmission shaft, auxiliary gears respectively connected to the plurality of auxiliary transmission shafts, and internal gears respectively connected to the plurality of auxiliary gears; A fan assembly, wherein the fan assembly is connected to the internal gear; A quick response commutator disc assembly is connected to the inlet flow channel and the return flow channel and is used to control the spraying of the liquid medicine.

[0006] The present invention generates an air flow field around the spray area through a fan assembly, and the air flow field is used to protect the sprayed liquid droplets, thereby reducing the influence of external airflow on the movement of the droplets; in addition, by providing a fast response commutator disc assembly, the delay in opening and closing the nozzle is reduced, and the pressure fluctuation and impact caused by the opening and closing of the valve are reduced.

[0007] Optionally or preferably, it further comprises a centrifugal disc assembly, wherein the centrifugal disc assembly is fixedly connected to the end of the central transmission shaft, and comprises a centrifugal disc; The centrifugal disk comprises an upper centrifugal disk and a lower centrifugal disk. The upper centrifugal disk is provided with a plurality of fan-shaped connecting holes. The upper centrifugal disk and the lower centrifugal disk are connected via the plurality of fan-shaped connecting holes.

[0008] The present invention further improves the atomization effect of the medicine liquid by arranging a centrifugal disc assembly at the end of the central transmission shaft; on the other hand, compared with the traditional centrifugal disc, the multi-layer centrifugal disc provided by the present invention can reduce the adhesion between the medicine liquids and avoid the dripping of the residual medicine liquid.

[0009] Optionally or preferably, the fan assembly includes lower sleeve and upper sleeve fans, and the lower sleeve and upper sleeve fans are respectively connected to the internal gear.

[0010] The fan assembly in the present invention provides an anti-drifting method based on the gas-liquid coupling flow field of reverse swirl and axial push. The upper sleeve fan is driven in reverse by the internal gear, thereby constructing a spiral flow field in the opposite direction of the central transmission shaft, and generating a linear airflow field with axial push characteristics at the same time. The double flow fields form a composite airflow potential field around the nozzle, and synergistically construct a dynamic gas-liquid coupling field in the spray area to form a low-drift, high-coverage liquid medicine transmission path. The gas-liquid coupling flow field suppresses the disturbance effect of the ambient wind on the fog field, effectively suppresses the drift effect after the discrete atomization of the liquid medicine, enhances the targeted transportation capability of the droplets, and significantly improves the droplet attachment efficiency and operation accuracy.

[0011] Optionally or preferably, the housing assembly further comprises a pair of upper housings and a pair of lower housings that are engaged with each other; The upper sleeve fan is connected to the upper shell through an upper thrust ball bearing; the lower sleeve is connected to the lower shell through a lower thrust ball bearing.

[0015] The electromagnetic valve core of the fast-response commutation disc assembly of the present invention integrates high-pressure sealing, fluid boundary guidance and path-stable commutation. By dynamically suppressing the transient flow field of valve switching, the interference of fluid turbulence on the centrifugal disc liquid supply process is reduced, thereby achieving precise control of the flow rate and direction of the liquid medicine.

[0016] Optionally or preferably, the electromagnetic valve core comprises a valve core 1 and a valve core 2 connected to each other, the valve core 1 is used to control the opening and closing of the circulation flow channel, and the valve core 2 is used to control the opening and closing of the spray flow channel; The solenoid valve coil and the spring are respectively arranged at two ends of the valve core 2.

[0018] The present invention realizes uneven distribution of radial tensile force at the fluid distribution level through the difference in opening angles of the upper centrifugal disk and the lower centrifugal disk. The liquid filaments decompose and the droplets collide and split in the radial centrifugal field to form multi-stage progressive atomization, and constructs a particle-level atomization model with segmented energy dissipation characteristics, thereby improving the atomization effect of the nozzle under large-flow spray.

[0019] Optionally or preferably, the centrifugal disc assembly further comprises a fixed disc, and the fixed disc is used to press the fast response commutator disc assembly onto the lower housing.

[0022] Based on the above technical solution, the present invention can at least produce the following technical effects: (1) The fast response commutation disc assembly is a dual-channel dynamic commutation mechanism design based on electromagnetic drive and elastic recovery. The electromagnetic valve core can simultaneously control the on-off of the circulation flow channel and the spray flow channel.

[0033] In this embodiment, sleeves are sleeved on the outer sides of the central transmission shaft 201 and the two auxiliary transmission shafts 202 for axial positioning of the central transmission shaft 201 and the auxiliary transmission shafts 202 .

[0034] In this embodiment, the fan assembly 30 includes a lower sleeve 301 and an upper sleeve fan 302; the inner ring of the upper sleeve fan 302 is stepped and has 6 tenons, and the outer ring has fan blades and a protective cover; the upper sleeve fan 302 is connected to the internal gear 205 through a mortise and tenon structure, and is positioned and supported by the internal gear 205 and the upper thrust ball bearing 206.

[0035] In actual operation, the upper sleeve fan 302 rotates with the internal gear 205 to generate a downward airflow, which helps the liquid medicine to be atomized and reduces the drift of the droplets. At the same time, the generated airflow collides with the droplets flying out of the centrifugal disk, further improving the atomization effect.

[0036] The lower sleeve 301 is also stepped and provided with two tenons, connected to the internal gear 205 through a mortise and tenon structure, and located between the internal gear 205 and the lower thrust ball bearing 207 to help position and support the lower thrust ball bearing 207 and the internal gear 205 .

[0037] In order to achieve rapid response of the nozzle opening and closing valve and reduce the pressure fluctuation and impact caused by the opening and closing of the valve, in this embodiment, a rapid response commutator disc assembly 40 is also provided in the nozzle, and the rapid response commutator disc assembly 40 is arranged between the lower shell and the centrifugal disc assembly 50.

[0038] Specifically, the above-mentioned rapid response commutator disc assembly 40 includes an upper commutator disc 401 and a lower commutator disc 402 that are interlocked. The upper commutator disc 401 is respectively provided with a water inlet hole 406 and a return hole 407; the lower commutator disc 402 is provided with a plurality of spray holes 408.

[0039] The above-mentioned water inlet hole 406 and return hole 407 are respectively connected to the inlet flow channel 1011 and the return flow channel 1021, and a positioning seal 409 is provided at the connection; in this embodiment, a circulation flow channel 410 is opened between the water inlet hole 406 and the return hole 407, and a spray flow channel 411 is opened between the water inlet hole 406 and the spray hole 408.

[0040] In order to control the opening and closing of the circulation channel 410 and the spraying channel 411 , a quick response control element is provided between the upper commutator plate 401 and the lower commutator plate 402 .

[0041] Specifically, the above-mentioned rapid response control component includes a solenoid valve core 403, a solenoid valve coil 404 and a spring 405; wherein the solenoid valve core 403 can be movably arranged between the circulation channel 410 and the spray channel 411; the solenoid valve coil 404 acts on the solenoid valve core 403 and is used to control the switching state of the solenoid valve core 403; the spring 405 is used to provide axial restoring force to the solenoid valve core 403.

[0042] In actual operation, when the nozzle is in the closed state, the liquid medicine will not be sprayed out from the spray hole 408. At this time, the solenoid valve core 403 is pushed up by the spring 405, the circulation channel 410 is in the open state, and the spray channel 411 is in the closed state. At this time, the liquid medicine will circulate in the water inlet hole 406, the circulation channel 410 and the return hole 407. When the nozzle is in the open state, the medicine liquid will be sprayed out from the spray hole 408. At this time, the solenoid valve coil 404 generates a force on the solenoid valve core 403 under the action of the signal, and pushes the solenoid valve core 403 downward, so that the spray flow channel 411 is in the open state, and the circulation flow channel 410 is closed at the same time. At this time, the medicine liquid will enter from the water inlet hole 406 and be sprayed out through the spray hole 408.

[0043] In this embodiment, the solenoid valve core 403 includes a valve core 1 4031 and a valve core 2 4032 connected to each other, wherein the valve core 1 4031 is a shorter cylindrical structure and the valve core 2 4032 is a longer cylindrical structure; the solenoid valve coil 404 and the spring 405 are respectively arranged at both ends of the valve core 2 4032.

[0044] In this embodiment, positioning seals 409 are provided at both the water inlet hole 406 and the return hole 407. The positioning seals 409 are used to seal the connection and limit the movement of the commutator disk in the horizontal direction.

[0045] In order to further improve the dispersion effect of the medicine, in this embodiment, a centrifugal disc assembly 50 is provided at the lower end of the central transmission shaft 201 .

[0046] Specifically, the centrifugal disc assembly 50 includes a centrifugal disc 501 and a fixed disc 502 .

[0047] In this embodiment, the centrifugal disk 501 is a double-layer centrifugal disk, including an upper centrifugal disk 5011 and a lower centrifugal disk 5012, wherein the upper centrifugal disk 5011 is symmetrically provided with two fan-shaped connecting holes 5013, and the upper centrifugal disk 5011 and the lower centrifugal disk 5012 are connected via the plurality of fan-shaped connecting holes 5013.

[0048] Furthermore, the cone angle of the upper centrifugal disc 5011 is α , the cone angle of the lower centrifugal disk 5012 is β , α - β≥10°, that is, the cone angle of the upper centrifugal disk 5011 is at least 10° greater than the cone angle of the lower centrifugal disk 5012.

[0049] The present embodiment provides a fast-response triple atomizing air-delivered centrifugal nozzle, and its working process is as follows: S1. Install the nozzle and start the sprayer. Fix the entire nozzle on the UAV frame or the sprayer boom through the installation part of the upper shell; use a coupling to connect the central transmission shaft 201 to the electric external drive shaft; connect the external inlet pipe to the inlet joint 101, and connect the external return pipe to the return joint 102; after installing the nozzle, start the sprayer to operate; turn on the water pump when the sprayer is operating, and the liquid medicine will circulate in the nozzle until the quick response commutation disc assembly opens the valve; S2, the nozzle pre-start phase, during the operation, the pest detection algorithm is used to detect pests and diseases in crops. When the pest target is detected, the nozzle is pre-started first, that is, the motor is started first.

[0050] First, the motor inputs power to the central transmission shaft 201, and the central transmission shaft 201 drives the central gear 203 and the double-layer centrifugal disk 501 to rotate in the same direction as the central transmission shaft 201, and the central gear 203 drives the two sub-gears 204 to rotate in the opposite direction to the central transmission shaft 201, and the two sub-gears 204 drive the internal gear 205 to rotate in the opposite direction to the central transmission shaft 201, and the internal gear 205 drives the upper sleeve fan 302 to rotate in the opposite direction to the central transmission shaft 201, and the upper sleeve fan 302 rotates to generate an airflow that rotates in the opposite direction to the central transmission shaft 201 and moves axially along the central transmission shaft 201. The airflow will reduce the influence of the airflow generated by the rotation of the drone wings on the spraying, and at the same time reduce the influence of the ambient wind on the spray mist, reduce the drift of the spray mist, and help the atomization of the liquid medicine; S3, during the spraying stage, when the nozzle is aimed at the pest target, the solenoid valve coil 404 is energized, and the coil and the solenoid valve core 403 generate repulsive force. The solenoid valve core 403 overcomes the spring force and moves, and opens the spraying flow channel 411. The liquid medicine with a certain flow rate will quickly flow to the spraying hole 408, and spray the liquid medicine into the double centrifugal disk 501 through the 8 spraying holes 408 arranged in an annular manner.

[0051] During the spraying process, since the liquid medicine is a high-pressure liquid, the liquid medicine will be broken and atomized to a certain extent during the spraying process, which is the first level of atomization; about half of the sprayed liquid medicine is sprayed on the upper centrifugal disk 5011, and the other half of the liquid medicine passes through the upper centrifugal disk 5011 through the fan-shaped holes 5013 of the upper centrifugal disk 5011 and enters the lower centrifugal disk 5012; the opening angle of the upper centrifugal disk 5011 is 10° larger than the opening angle of the lower centrifugal disk. The liquid medicine is thrown out of the centrifugal disk under the centrifugal action of the upper and lower centrifugal disks, and the liquid medicine in the lower centrifugal disk 5012 hits the lower edge of the upper centrifugal disk 5011, and the liquid medicine thrown out of the upper centrifugal disk 5011 hits the fixed disk 502. During the process of being centrifugally thrown out, the medicine liquid is first drawn into liquid filaments, and then dispersed into small droplets. After being impacted, it is further dispersed and atomized. This is the second level of atomization. When the medicine liquid is thrown out, it rotates in the same direction as the central transmission shaft 201, while the airflow rotates in the opposite direction to the central transmission shaft 201 and moves axially along the central transmission shaft 201. The airflow collides with the medicine liquid, further helping the medicine liquid to be atomized. This is the third level of atomization. After the triple atomization, the medicine mist will be stably delivered to the spraying target by the airflow generated by the fan.

[0052] S4, the final stage, when the spraying amount reaches the expected amount, stop spraying.

[0053] After the spraying is completed, the solenoid valve coil 404 is disconnected immediately, and the battery valve core 403 is acted upon by the spring force to close the spraying flow channel 411. After the spraying flow channel 411 is completely closed, the external drive motor is turned off. At this time, the liquid medicine in the centrifugal disc 501 is completely thrown out, and there will be no problem of residual liquid medicine dripping from the spray head.
