Description

Technical Field

[0001] This invention relates to the field of agricultural technology, specifically to a ground-mounted spray quality parameter real-time detection device. Background Technology

[0002] In agricultural practice, ground-mounted sprayers have been widely used in foliar fertilization in orchards, tea gardens, and greenhouse agriculture due to their advantages such as fixed installation, wind resistance, and uniform application. Spray quality parameters, such as droplet volume median diameter (VMD), distribution uniformity, deposition density, and drift ratio, directly determine fertilizer utilization and environmental safety, necessitating efficient and reliable on-site monitoring technologies to support operational optimization.

[0003] Current mainstream detection methods in the industry rely on manual handheld sensors for fixed-point sampling or drones equipped with sensors for dynamic scanning over the spray area. However, manual detection is inefficient, has limited coverage, and is prone to subjective errors. While drone detection improves automation, the high-speed rotation of the rotors generates strong downwash airflow, severely disturbing the natural flow of the spray field. This forces droplet trajectories to deviate, compresses or diffuses cloud structures, leading to distorted deposition distribution and abnormally high drift ratios. Consequently, the acquired parameters cannot accurately guide spray parameter control, resulting not only in fertilizer waste and potential pesticide damage risks but also hindering the upgrading of fertilization operations towards intelligent agriculture. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the present invention aims to provide a ground-mounted spray quality parameter real-time detection device, comprising a ground-mounted fixing bracket, a spray system, and a detection system. The spray system includes a material cylinder and an extension shaft coaxially arranged with the material cylinder. A helical interface is provided on one side of the material cylinder, and a first rotating seat is coaxially rotatably mounted on the top of the material cylinder. A spray head is mounted on the first rotating seat. A bushing is coaxially sleeved on the outside of the extension shaft inside the material cylinder. The bushing is coaxially connected to the first rotating seat, and helical blades that fit against the inner wall of the material cylinder are provided around the bushing. The helical blades are located above the helical interface. The detection system includes a second rotating seat coaxially rotatably mounted on the top of the extension shaft, a laser diffraction sensor mounted on the second rotating seat, and a transmission system that drives the first and second rotating seats. The transmission system drives the laser diffraction sensor to rotate around the axis of the extension shaft for comprehensive scanning and detection when the spray system rotates to spray.

[0005] To enable the switching between static and dynamic detection modes in the detection system, the following features are specifically included: The transmission system comprises a reduction gear set and a fixed base. The fixed base is fixedly mounted on an extension shaft. The top of the first rotating base is provided with a toothed groove surrounding the outer wall. The driven gear at the input end of the reduction gear set meshes with the toothed groove. The output end of the reduction gear set is coaxially mounted with a transmission shaft, which is parallel to the extension shaft. A lifting plate is rotatably mounted on the second rotating base. A driven shaft coaxially mounted with the transmission shaft is rotatably mounted on the lifting plate. The driven shaft is connected to the second rotating base via a synchronous belt. The transmission system is equipped with an electric push rod for driving the lifting plate to move along the axis of the extension shaft. When the electric push rod drives the lifting plate to descend until the driven shaft contacts the transmission shaft, the driven shaft rotates synchronously with the transmission shaft.

[0006] Preferably, the top end of the drive shaft is eccentrically provided with a plug hole, the axis of the plug hole is parallel to the axis of the drive shaft, the bottom end of the driven shaft is provided with a mounting hole coaxial with the plug hole, a plug post and a spring are coaxially provided in the mounting hole, and the elastic force of the spring causes the plug post to protrude from the lower surface of the lifting plate.

[0007] To ensure that the plug can be quickly inserted into the plug hole, the following feature is specifically provided: the diameter of the plug is not greater than the inner diameter of the plug hole.

[0008] To achieve positional stability of the transmission system, the following features are specifically provided: a horizontal positioning bolt is inserted into the fixed base, the positioning bolt passes through a radial hole provided on the extension shaft, and a locking nut is screwed onto the positioning bolt.

[0009] To maintain the operation of the detection system, the following features are specifically provided: the mounting base is equipped with an independent power supply for supplying power to the laser diffraction sensor and the electric push rod.

[0010] To ensure that the liquid medicine in the barrel can enter the rotating spray head, the following feature is specifically provided: the spray head is provided with a connecting pipe that connects to the inside of the first rotating seat.

[0011] To reduce resistance to the rotating bushing, the following feature is specifically provided: several bearings are coaxially arranged at the connection between the extension shaft and the bushing.

[0012] To improve the overall stability of the equipment during operation, the following features are specifically designed: the ground-mounted fixing bracket includes a vertically downward extending rod and a horizontal stabilizing plate, the rod having a downward tapering angle, and the ground-mounted fixing bracket being inserted into the stabilizing plate to fit against the ground surface.

[0013] Preferably, the outer wall of the material cylinder is provided with a plurality of support plates that connect to the stabilizing plate, and the support plates are distributed at equal angles around the outer wall of the material cylinder.

[0014] The advantages of this invention compared to the prior art are as follows: The detection system in this invention is installed in one piece on the upper part of the spraying system. The laser diffraction sensor automatically rotates and scans during spraying operations through the transmission system, which completely avoids measurement deviations introduced by the airflow disturbance of the drone rotor, the obstruction of the drone body and manual hand operation, ensuring that the detection data truly reflects the original flow state of the spray and ensuring the upgrade of fertilization operations to intelligent agriculture.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Reference Figures 1 to 11 : A ground-mounted spray quality parameter real-time detection device includes a ground-mounted fixing bracket 1, a spray system 2, and a detection system 3. The spray system 2 includes a material cylinder 2a and an extension shaft 2a1 coaxially arranged with the material cylinder 2a. A spiral interface 2a2 is provided on one side of the material cylinder 2a. A first rotating seat 2b is coaxially rotatably mounted on the top of the material cylinder 2a. A spray head 2c is mounted on the first rotating seat 2b. A bushing 2d is coaxially sleeved on the outside of the extension shaft 2a1 inside the material cylinder 2a. The bushing 2d is coaxially connected to the first rotating seat 2b. The 2d circumference is provided with a spiral blade 2d1 that fits against the inner wall of the material cylinder 2a, and the spiral blade 2d1 is located above the spiral interface 2a2; the detection system 3 includes a second rotating seat 3a coaxially rotatably mounted on the top of the extension shaft 2a1, a laser diffraction sensor 3b mounted on the second rotating seat 3a, and a transmission system 4 that drives the first rotating seat 2b and the second rotating seat 3a. The transmission system 4 drives the laser diffraction sensor 3b to rotate around the axis of the extension shaft 2a1 to perform all-round scanning detection when the spray system 2 rotates and sprays.

[0030] When using this application, workers can combine it with a common ground-mounted sprayer, plan the installation location in advance to facilitate real-time monitoring of overall quality parameters, and then securely implant the entire system into the field soil using the ground-mounted fixing bracket 1. After starting the spraying system 2, the liquid pesticide is injected into the cavity through the spiral interface 2a2 on the side wall of the barrel 2a. Since the bushing 2d has spiral blades 2d1 that fit against the inner wall of the barrel 2a, the liquid pesticide drives the bushing 2d to rotate under high pressure. At the same time, it drives the first rotating seat 2b, which is coaxially connected, to drive the spray head 2c to rotate and perform spraying operations. Meanwhile, the transmission system 4 accurately transmits the rotational power of the first rotating seat 2b to the second rotating seat 3a, which is coaxially mounted on the top of the extension shaft 2a1. This drives the laser diffraction sensor 3b to rotate synchronously with the spray head 2c around the axis of the extension shaft 2a1, performing a 360° dynamic scan of the droplet field formed by the spray, and capturing core quality parameters such as droplet size distribution and concentration in real time. In this embodiment, the detection system 3 is integrated and installed on the upper part of the spray system 2. The laser diffraction sensor 3b is rotated and scanned during spraying operations through the transmission system 4, which completely avoids the measurement deviations introduced by the airflow disturbance of the drone rotor, the obstruction of the fuselage and manual hand operation, and ensures that the detection data truly reflects the original flow state of the spray.

[0031] To enable the switching between static and dynamic detection modes in the detection system 3, the following features were specifically configured: The transmission system 4 includes a reduction gear set 4a and a fixed seat 4b. The fixed seat 4b is fixedly mounted on the extension shaft 2a1. The top of the first rotating seat 2b is provided with a toothed groove 2b1 surrounding the outer wall. The driven gear 4a1 at the input end of the reduction gear set 4a meshes with the toothed groove 2b1. The output end of the reduction gear set 4a is coaxially provided with a transmission shaft 4a2, which is parallel to the extension shaft 2a1. The second rotating seat 3a is rotatably mounted on the lifting plate 3c. The lifting plate 3c is rotatably mounted with a driven shaft 3c1 coaxially with the transmission shaft 4a2. The driven shaft 3c1 and the second rotating seat 3a are connected by a synchronous belt 3c2. The transmission system 4 is provided with an electric push rod 4b1 for driving the lifting plate 3c to move along the axis of the extension shaft 2a1. When the electric push rod 4b1 drives the lifting plate 3c to descend until the driven shaft 3c1 is in contact with the transmission shaft 4a2, the driven shaft 3c1 rotates synchronously with the transmission shaft 4a2.

[0032] The top of the drive shaft 4a2 is eccentrically provided with a insertion hole 4a3, the axis of the insertion hole 4a3 is parallel to the axis of the drive shaft 4a2, and the bottom of the driven shaft 3c1 is provided with a mounting hole 3c3 coaxial with the insertion hole 4a3. The mounting hole 3c3 is coaxially provided with a insertion post 3c4 and a spring 3c5. The elastic force of the spring 3c5 causes the insertion post 3c4 to protrude from the lower surface of the lifting plate 3c.

[0033] In this embodiment, when the spray system 2 is running, the first rotating seat 2b rotates, driving the toothed groove 2b1 to drive the driven gear 4a1. After being reduced in speed by the reduction gear set 4a, the power is output by the transmission shaft 4a2. Figures 1 to 5 As shown, in static detection mode, the control system commands the electric push rod 4b1 to drive the lifting plate 3c to move upward along the axis of the extension shaft 2a1 to the separation position. At this time, the driven shaft 3c1 disengages from the transmission shaft 4a2, power transmission is interrupted, and the second rotating seat 3a and the laser diffraction sensor 3b remain stationary, achieving unidirectional precise sampling when the spray system 2 is working; as Figure 7 and Figure 8 As shown, when switching to dynamic detection mode in this embodiment, the electric push rod 4b1 drives the lifting plate 3c to descend, so that the bottom end of the moving shaft 3c1 approaches the top end of the transmission shaft 4a2. When the insertion post 3c4 contacts the top end of the transmission shaft 4a2, the compression spring 3c5 enters the mounting hole 3c3. When the transmission shaft 4a2 rotates to the point where the insertion hole 4a3 is coaxial with the insertion post 3c4, the insertion post 3c4 automatically inserts into the insertion hole 4a3 under the elastic force of the spring 3c5, establishing a rigid transmission connection. The driven shaft 3c1, in conjunction with the synchronous belt 3c2, drives the second rotating seat 3a to rotate synchronously, so that the laser diffraction sensor 3b performs 360° continuous scanning detection around the axis of the extension shaft 2a1. In this embodiment, the electric push rod 4b1 precisely controls the displacement of the lifting plate 3c. In conjunction with the transmission shaft 4a2, driven shaft 3c1, insertion post 3c4 and insertion hole 4a3, the electric rapid switching between static and dynamic detection modes is achieved. In static mode, the detection system 3 is completely stationary, completely eliminating vibration interference from the spray and improving the accuracy of single-point detection. In dynamic mode, the system strictly synchronizes rotation and scans to accurately reproduce the spatial distribution of the spray field. In this embodiment, the reduction gear set 4a can optimize the speed matching so that the laser diffraction sensor 3b scans at an appropriate speed, ensuring the quality of data acquisition.

[0034] To ensure that the plug pin 3c4 can be quickly inserted into the plug hole 4a3, the following features are specifically designed: The diameter of the plug 3c4 is not greater than the inner diameter of the plug hole 4a3.

[0035] To achieve positional stability of the transmission system 4, the following features are specifically designed: A horizontal positioning bolt 4b2 is inserted into the fixed base 4b. The positioning bolt 4b2 passes through the radial hole 2a3 provided on the extension shaft 2a1. A locking nut 4b3 is screwed onto the positioning bolt 4b2.

[0036] like Figure 4 and Figure 9As shown, in this embodiment, the fixed seat 4b is horizontally inserted through the positioning bolt 4b2 and precisely passes through the pre-set radial hole 2a3 on the extension shaft 2a1. Then, the locking nut 4b3 is tightened at the exposed end of the positioning bolt 4b2, so that the fixed seat 4b and the extension shaft 2a1 form a rigid mechanical lock, completely eliminating the degree of freedom of the fixed seat 4b in the axial displacement and circumferential rotation direction. This ensures that the entire transmission system 4 remains stable under the continuous operation of the spray system 2, field vibration, or wind load interference, and maintains stable meshing between the driven gear 4a1 and the tooth groove 2b1 of the first rotating seat 2b, providing a guarantee for subsequent power transmission.

[0037] To maintain the operation of detection system 3, the following features are specifically configured: The mounting base 4b is equipped with an independent power supply for supplying power to the laser diffraction sensor 3b and the electric actuator 4b1.

[0038] The independent power supply can be any existing technology, which will not be elaborated on here and is not shown in the figure.

[0039] like Figure 4 As shown, in order to ensure that the liquid medicine in the barrel 2a can enter the rotating spray head 2c, the following features are specifically designed: The spray head 2c is provided with a connecting pipe 2c1 that connects to the inside of the first rotating seat 2b.

[0040] To reduce the resistance to the rotating bushing 2d, the following features are specifically designed: Several bearings 2d2 are coaxially arranged at the connection between the extension shaft 2a1 and the bushing 2d.

[0041] like Figure 6 As shown, in this embodiment, the bearing 2d2 transforms the sliding friction between the bushing 2d and the extension shaft 2a1 into low-resistance rolling friction, enabling the bushing 2d to rotate smoothly and efficiently, significantly reducing the rotational resistance of the bushing 2d, reducing drive energy consumption, and eliminating the risk of shaking and jamming during rotation.

[0042] To improve the overall stability of the equipment during operation, the following features are specifically designed: The ground-mounted fixing bracket 1 includes a vertically downward extending insertion rod 1a and a horizontal stabilizing plate 1b. The insertion rod 1a has a downward tapering angle, and the ground-mounted fixing bracket 1 is inserted into the stabilizing plate 1b to conform to the ground surface.

[0043] The outer wall of the barrel 2a is provided with several support plates 2a4 that connect to the stabilizing plate 1b. The support plates 2a4 are distributed at equal angles around the outer wall of the barrel 2a.

[0044] like Figure 1 and Figure 2As shown, in this embodiment, during installation, the tapered rod 1a of the fixed bracket 1 is vertically pressed into the soil. The tapered rod 1a allows for smooth entry into the soil and enhances the anchoring depth. The horizontally positioned stabilizing plate 1b closely adheres to the ground surface, forming a large-area support surface. Several support plates 2a4, evenly distributed around the outer wall of the material cylinder 2a, rigidly connect the material cylinder 2a to the stabilizing plate 1b, forming a radial triangular support frame. During operation, the dynamic loads generated by the spray system 2, such as the recoil force, wind load disturbance, and rotational inertia of the detection system 3, are evenly transmitted to the stabilizing plate 1b via the support plates 2a4, and then dispersed to the deep soil through the rod 1a, effectively suppressing the shaking of the entire machine and ensuring the stability of the extension shaft 2a1, spray head 2c, and laser diffraction sensor 3b during operation.

[0045] Working principle: During use, the operator securely implants the entire system into the field soil using the ground-mounted fixing bracket 1. After starting the spraying system 2, the liquid pesticide is injected into the cavity through the spiral interface 2a2 on the side wall of the feed cylinder 2a. Under high pressure, the liquid pesticide pushes the bushing 2d to rotate, which in turn drives the first rotating seat 2b, coaxially connected to the spray head 2c, to rotate and perform spraying operations. At the same time, the transmission system 4 precisely transmits the rotational power of the first rotating seat 2b to the second rotating seat 3a, coaxially mounted on the top of the extension shaft 2a1, driving the laser diffraction sensor 3b to strictly follow the spray head 2c and rotate synchronously around the axis of the extension shaft 2a1, performing a 360° dynamic scan of the droplet field formed by the spray, and capturing core quality parameters such as droplet size distribution and concentration in real time.

[0046] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
