Description

Technical Field

[0001] This utility model relates to the field of agricultural plant protection machinery technology, and in particular to a height-adjustable spraying device for tea tree pests. Background Technology

[0002] As an important economic crop, tea trees are susceptible to various pests during their growth. These pests often congregate on the undersides of tea leaves, affecting the growth of tea trees by eating the leaf tissue and sucking sap, leading to reduced tea yield and quality. Therefore, precise spraying of the undersides of tea leaves is a crucial step in ensuring the healthy growth of tea trees and improving tea yield and quality. Currently, tea cultivation is mainly carried out in large-scale tea gardens, where tea trees are densely planted, and the height of tea trees at different growth stages varies significantly, which poses certain challenges to spraying operations.

[0003] In existing tea tree pest spraying technologies, common methods mainly rely on manual spraying equipment carried on the back or the use of simple mechanical spraying devices. When using manual spraying equipment, workers must move the nozzle around the tea garden, which is not only labor-intensive and inefficient, but also makes it difficult to accurately control the nozzle height and direction, easily leading to missed or incorrect spraying when targeting the undersides of tea leaves at different heights. While simple mechanical spraying devices can reduce manual labor, most cannot adjust the spraying position according to the height of the tea trees, resulting in a limited spraying range and difficulty in covering the undersides of leaves at different heights, leaving some areas untreated. Furthermore, existing spraying devices lack intelligent monitoring and adjustment functions during the spraying process, failing to assess the coverage of the undersides of leaves in real time and adjust spraying parameters accordingly, easily leading to pesticide waste. Additionally, some key components are easily damaged during operation by pesticide residue, tree branches, etc., shortening the device's lifespan and failing to meet the needs of large-scale tea gardens for efficient, precise, and stable spraying.

[0004] Therefore, it is necessary to design a height-adjustable spraying device for tea tree pests to solve the above-mentioned technical problems. Summary of the Invention

[0005] In order to overcome the shortcomings of existing tea tree spraying devices, such as difficulty in adapting to spraying the back of tea tree leaves of different heights, easy omissions and mis-spraying, low efficiency due to reliance on manual operation, insufficient level of intelligence, serious waste of pesticide solution, easy damage to key components and short service life, this utility model provides a height-adjustable tea tree pest spraying device.

The liquid tank is located on the top of the autonomous mobile robot, and a screw cap is located on the top of the liquid tank. A liquid pump is located inside the liquid tank, and the output port of the liquid pump is connected to and communicates with the delivery hose. The delivery hose passes through the top of the liquid tank and extends downward, connecting and communicating with the telescopic hose. The lower end of the telescopic hose is connected and communicates with the atomizing nozzle. A multi-section electric telescopic rod is installed on the front side of the autonomous mobile robot, and the telescopic ends of the multi-section electric telescopic rod are fixedly connected to the connecting frame. The left side of the connecting frame extends downward to form a mounting part. The rotating shaft is rotatably connected to the mounting part through a bearing, allowing it to rotate back and forth around the rotating shaft. A fan is installed on the front side of the rotating shaft, and a controller is installed on the front side of the liquid tank. The autonomous mobile robot, the liquid pump, and the multi-section electric telescopic rod are all electrically connected to the controller.

[0007] Optionally, it also includes a drive motor. The drive motor with its output shaft facing the rear is installed on the top right side of the mounting part. The drive motor is controlled by the controller to make its output shaft perform periodic forward and reverse rotation. The drive motor is electrically connected to the controller.

[0008] Optionally, it also includes a transmission belt, with the output shaft of the drive motor connected to the driving pulley and the rear end of the rotating shaft fixedly connected to the driven pulley. The two pulleys are connected by the transmission belt, so that the rotational motion of the drive motor is transmitted to the rotating shaft to drive the whole to reciprocate at a limited angle.

[0009] Optionally, it also includes an air outlet pipe, with the air outlet of the fan facing to the left. The air outlet pipe is connected to and communicates with the left side of the fan. The atomizing nozzle extends into and is connected to the air outlet pipe. The left side of the air outlet pipe is in the shape of a gradually expanding trumpet.

[0010] Optionally, it also includes a connecting plate and a vision recognition device. The connecting plate is fixedly connected to the top left side of the air outlet pipe, and the vision recognition device is installed on the left side of the connecting plate. The vision recognition device is electrically connected to the controller.

[0011] Optionally, it also includes a protective cover, which is placed over the vision recognition device and fixedly connected to the left side of the connecting plate.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention sets up a multi-section electric telescopic rod connected to a connecting frame, which drives the rotating shaft, fan, air outlet pipe and atomizing nozzle to lift and lower as a whole, realizing flexible adjustment of the spraying height. It can adapt to the canopy height of tea trees at different growth stages, achieving the effect of precise target spraying, improving the uniformity of pesticide coverage and control efficiency.

[0013] 2. This utility model, by setting a drive motor in the installation part and driving the rotating shaft to reciprocate at a limited angle via a transmission belt, makes the atomizing nozzle and the air outlet pipe swing synchronously with the fan, thereby expanding the spraying angle and coverage of the medicine mist, achieving the effects of enhancing the penetration of the medicine mist, effectively spraying it to the back of tea leaves, and reducing missed spraying and double spraying.

[0014] 3. This utility model achieves intelligent adjustment of spraying parameters by setting a connecting plate and installing a visual recognition device on the top left side of the air outlet pipe, combined with the controller to identify and control the tea tree canopy and pest and disease areas. At the same time, a protective cover is used to protect the visual recognition device, which improves the level of intelligence of spraying operations, reduces pesticide waste, and ensures the stable operation of key components.

The lower end of the telescopic hose 24 is connected to and connected to... The system includes an atomizing nozzle 25 and an autonomous mobile robot 1 with a multi-section electric telescopic rod 30 mounted on its front side. The telescopic ends of the multi-section electric telescopic rod 30 are connected to a connecting frame 31 by bolts. The connecting frame 31 extends downward on its left side to form a mounting part. A rotating shaft 33 is rotatably connected to the mounting part through a bearing, allowing it to rotate back and forth around the shaft. A fan 35 is mounted on the front side of the rotating shaft 33. The fan 35 is a self-powered independent fan used to generate auxiliary airflow. A controller 4 is mounted on the front side of the liquid tank 20. The autonomous mobile robot 1, the liquid pump 22, and the multi-section electric telescopic rod 30 are all electrically connected to the controller 4.

[0021] like Figure 3 and 4 As shown, it also includes a drive motor 32, a transmission belt 34, an air outlet pipe 36, a connecting plate 37, a vision recognition device 38, and a protective cover 39. The drive motor 32, with its output shaft facing rearward, is mounted on the top right side of the mounting unit. The drive motor 32 is controlled by a controller to make its output shaft perform periodic forward and reverse rotation. The drive motor 32 is electrically connected to the controller 4. The connecting bracket 31 synchronously drives the drive motor 32, the rotating shaft 33, the fan 35, the air outlet pipe 36, and the atomizing nozzle 25 to move up and down through the mounting unit. The air outlet of the fan 35 faces left. The output shaft of the drive motor 32 is connected to the drive pulley through a reducer. The controller controls the motor's forward and reverse rotation, realizing the reciprocating oscillation of the rotating shaft. The rear end of the rotating shaft 33 is connected to a driven pulley by bolts. The two pulleys are connected by a transmission belt 34, which transmits the rotational motion of the drive motor 32 to the rotating shaft 33, causing the whole to reciprocate at a limited angle. The left side of the fan 35 is connected to and connected to the air outlet pipe 36. The atomizing nozzle 25 extends into the air outlet pipe 36 and is connected to it. The left side of the air outlet pipe 36 is gradually expanding into a trumpet shape. The top left side of the air outlet pipe 36 is connected to the connecting plate 37 by bolts. A vision recognition device 38 is installed on the left side of the connecting plate 37. The vision recognition device 38 is electrically connected to the controller 4. The protective cover 39 is placed over the vision recognition device 38 and is connected to the left side of the connecting plate 37 by bolts.

[0022] When this device is needed, the autonomous mobile robot 1 is first moved to the tea garden operation area and moves stably between the tea tree rows using its autonomous movement capability. The liquid tank 20 is set on the top of the autonomous mobile robot 1 to store the liquid required for controlling tea tree pests. The cap 21 is easy to add and seal. The liquid pump 22 is started under the control of the controller 4 and delivers the liquid to the atomizing nozzle 25 through the delivery hose 23 and the telescopic hose 24.

[0023] The multi-section electric telescopic pole 30 is installed on the front side of the autonomous mobile robot 1. Its telescopic end is fixedly connected to the connecting frame 31, which drives the connecting frame 31 and the installation part to rise and fall as a whole, thereby adjusting the vertical height of the atomizing nozzle 25 to adapt to the canopy position of tea trees at different growth stages and achieve precise longitudinal targeting.

[0024] The mounting section is rotatably connected to a rotating shaft 33, which is a cylindrical rotating shaft structure. The fan 35, air outlet pipe 36, and atomizing nozzle 25 are fixed on it. A drive motor 32 is located on the top right side of the mounting section. The drive motor 32 is electrically connected to the controller 4. When the controller 4 issues a command, the drive motor 32 starts, and its output shaft drives the active pulley to rotate. Through the transmission belt 34, the driven pulley is driven to rotate. The driven pulley is connected to the rotating shaft 33, thereby driving the entire rotating shaft 33 to rotate back and forth around its axis from 30° to 180°. The rotating shaft 33 is equipped with an angle limit switch or encoder, which is electrically connected to the controller 4 to limit the swing angle. This rotational action causes the fan 35, air outlet pipe 36, and atomizing nozzle 25 to rotate synchronously as a whole, expanding the coverage range of the pesticide mist in the horizontal direction, which helps to evenly spray the pesticide solution to all angles of the tea tree canopy and improve the prevention and control effect.

[0025] The blower 35 is a self-powered independent blower 35, fixed on the rotating shaft 33, with the air outlet facing the left side, continuously generating auxiliary airflow. The left side of the blower 35 is connected to and connected to the air outlet pipe 36. The nozzle of the atomizing nozzle 25 extends into the top of the air outlet pipe 36. When the liquid medicine is sprayed out, it intersects with the high-speed airflow to achieve efficient atomization and diffusion with the airflow. The left side of the air outlet pipe 36 is a gradually expanding trumpet shape, which helps to reduce the airflow velocity gradient, expand the distribution area of ​​the liquid medicine, and reduce drift.

[0026] A connecting plate 37 is fixedly connected to the top left side of the air outlet pipe 36. A vision recognition device 38 is installed on the left side of the connecting plate 37 to collect real-time image information of the tea trees in front. The vision recognition device 38 is used to detect obstacles and the outline of the tea trees in front to assist in locating the spraying position. The vision recognition device 38 transmits data to the controller 4. The controller 4 identifies the location of the tea trees, the height of the canopy, and the area of ​​pests and diseases, and dynamically adjusts the height of the multi-section electric telescopic rod 30, the rotation speed of the drive motor 32, the flow rate of the liquid pump 22, and the wind speed of the fan 35 to realize intelligent variable spraying. A protective cover 39 is placed outside the vision recognition device 38 to prevent the liquid from corroding and mechanical collisions, and to ensure the long-term stable operation of the system.
