Description

Technical Field

[0001] This invention relates to the field of agricultural implements technology, and in particular to a small-sized multi-functional machine and method for suppressing buds and protecting plants. Background Technology

[0002] Due to the diversity and complexity of tall crop growth, topping and bud-suppressing machines may struggle to adapt to different varieties and growing environments, requiring greater customization and adaptability. This includes considering factors such as the growth habits, stem structure, and growth rate of different plant varieties, as well as adjustments tailored to different planting environments. For example, various tall crops (tobacco, cotton, corn, etc.) have different growth characteristics and needs. Therefore, topping and bud-suppressing machines need to have more flexible and adjustable designs to meet the topping and bud-suppressing requirements of different crops, thereby improving the yield and quality of these crops.

[0003] Currently, topping and bud-suppressing machines still face some technical challenges, mainly in terms of accuracy and efficiency. For example, some machines may have errors in identifying and processing plant growth points, leading to unnecessary damage or omissions. Furthermore, due to the small size and complexity of crop growth points, topping and bud-suppressing machines may require higher-precision sensors and more advanced image recognition algorithms in actual operation to ensure accuracy and reduce misoperation. In general, further improving the intelligence and automation level of topping and bud-suppressing machines is key to solving these problems, thereby achieving more efficient and precise topping and bud-suppressing operations. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in current topping and bud-suppressing machines by providing a small, multi-functional plant protection machine that can accurately toplate tobacco plants and apply bud-suppressing agents in a single operation, while also performing pesticide spraying. This multi-functional plant protection machine can perform topping and bud-suppressing operations simultaneously. Because bud suppression occurs during the topping process, this device significantly improves operational efficiency and reduces labor requirements and workload. Furthermore, this machine can also be used independently as a plant protection machine, achieving multiple uses in one unit. This multi-functionality not only improves equipment utilization but also provides assistance in various agricultural production stages, such as pest and disease control and pesticide spraying, thus providing farmers with a more comprehensive and economical solution.

[0005] Specifically, in its first aspect, the primary objective of this invention is to provide a small-scale, multi-functional plant protection machine that suppresses bud growth, employing the following technical solution:

[0006] A small-scale multi-functional plant protection machine for suppressing bud growth includes a tracked chassis, a bud-suppressing device, a scissor lift platform, and a spray collection device. A gantry frame is mounted on the tracked chassis, and a scissor lift platform is located on top of the gantry frame. The scissor lift platform drives the bud-suppressing device to rise and fall. The bud-suppressing device includes a positioning radar, a bud-suppressing blade, a motor, a bud-suppressing agent nozzle, and a base. The base is connected to the scissor lift platform, and the motor is fixed to the base. The positioning radar is installed at both ends of the top of the base, and the motor output shaft is connected to the bud-suppressing blade. The bud-suppressing agent nozzle is installed above the bud-suppressing blade to spray the bud-suppressing agent onto the blade. Several drainage holes are provided on the bud-suppressing blade. A spray collection device is installed at the bottom of the gantry frame, located below the bud-suppressing blade.

[0007] The aforementioned multi-functional plant protection machine for suppressing buds can perform topping and bud suppression operations simultaneously. Since bud suppression occurs during the topping process, this device significantly improves operational efficiency and reduces labor requirements and workload.

[0008] As a further technical solution, a height identification radar is installed on the gantry frame, which works in conjunction with a positioning radar. When the tracked chassis moves along the plant, the positioning and height identification radars work together to measure the crop height in real time and transmit this data to the scissor lift platform. Based on the received signals, the system precisely locates the topping device, ensuring accurate topping of the tobacco growing point. Simultaneously, a multi-hole full-cone nozzle sprays a bud-suppressing agent, performing precise topping and bud-suppressing operations, thereby improving operational efficiency and effectiveness.

[0009] As a further technical solution, the fireworks collection device includes a collection guide and a detachable storage box; a fireworks collection guide and a detachable storage box are installed on each side of the gantry, the top of the fireworks collection guide is open and the bottom is connected to the detachable storage box, and a fan is installed inside the fireworks collection guide.

[0010] As a further technical solution, two fireworks collecting guides are symmetrically arranged below the top blade, with a certain gap between them.

[0011] As a further technical solution, a spraying device is also included.

[0012] As a further technical solution, the spraying device includes a spray bar and a medicine tank; a medicine tank is installed on each side of the gantry, and two spray bars are located at the front of the gantry, one spray bar is located on the left front of the gantry and the other spray bar is located on the right front of the gantry, with one spray bar corresponding to one medicine tank.

[0013] As a further technical solution, the sprout inhibitor nozzle is a multi-hole full-cone nozzle.

[0014] As a further technical solution, a GPS navigation system is installed on the tracked chassis, which is located on the top of the gantry.

[0015] As a further technical solution, the horizontal installation position of the topping and bud-suppressing device on the scissor-type operating platform can be adjusted. This device uses a scissor-type operating platform, which can adapt to tall crops of different heights and plant spacings, aiming to improve the accuracy of topping and bud suppression, reduce spraying costs, and significantly reduce chemical emissions into the environment. Simultaneously, the tracked chassis design enables it to maintain stable traction and passability in various terrains and environments, including wet, muddy, rugged terrain, as well as complex areas such as slopes and terraces.

[0016] Secondly, the present invention also provides a method for operating a small-scale bud-suppressing and plant protection multifunctional machine, as detailed below:

[0017] (1) Tracked chassis provides accurate location information and navigation guidance, assisting implements in carrying out precise operations in the field;

[0018] (2) The high-altitude identification radar and the positioning radar work together to accurately measure the position of the apical bud of tall crops;

[0019] (3) Based on the data measured by the height identification radar and the positioning radar, the scissor-type operating platform automatically adjusts the height of the topping and bud-suppressing device and adjusts the horizontal position of the topping and bud-suppressing device so that the cutting blade is located below the young leaves under the inflorescence at the top of the plant, and the bud-suppressing agent nozzle sprays the liquid evenly onto the topping blade.

[0020] (4) The motor controls the rotation of the topping blade. During the topping process, the topping blade applies the pesticide to the stem end of the crop after topping, ensuring precise spraying of the plant.

[0021] Compared with the prior art, the advantages and positive effects of this invention are:

[0022] (1) This equipment can complete topping and bud suppression operations in one go, greatly improving operational efficiency and reducing the demand for human resources in large-scale operations, thereby promoting the mechanization and large-scale development of the tobacco planting industry. At the same time, it can also be used independently as a plant protection machine to perform spraying operations, realizing the function of multiple uses in one machine.

[0023] (2) Scissor lift platforms have several advantages, including their stable scissor arm structure, which provides strong load-bearing capacity and reliable lifting performance. This structural design makes the platform stable and safe during lifting, suitable for work requirements at different heights. At the same time, scissor lift platforms are easy to operate and have low maintenance costs.

[0024] (3) The height identification radar and the positioning radar work together to determine the height of the terminal bud of tall crops, thereby achieving precise topping operations. This cooperation greatly improves the accuracy and efficiency of topping and bud suppression operations, ensuring that each crop is treated accurately.

[0025] (4) This machine uses GPS technology, which can provide accurate positioning and navigation, ensuring that the machine maintains a precise route when moving in the field; it can also record the operation trajectory and data, providing farmers with real-time farmland management information to help them make agricultural production decisions and management. This not only improves the accuracy and efficiency of topping and bud suppression operations, but also reduces repetitive operations and missed treatments, optimizes resource utilization, reduces labor demand, and thus greatly improves the overall productivity and economic benefits of the operation.

[0026] (5) The topping and bud-suppressing machine adopts a tracked chassis, which has excellent stability and traction, and can operate smoothly in various terrain conditions, including wet, muddy, rugged ground, as well as slopes and terraces. This design not only improves the machine's passability in complex environments, but also ensures the continuity and efficiency of operations, thereby significantly improving overall production efficiency and work quality.

[0027] (6) The multi-hole full-cone nozzle evenly sprays the pesticide solution onto the top surface of the topping blade, and then flows through the drainage holes from the top surface of the topping blade to the bottom surface and the blade edge. The topping blade then precisely applies the pesticide solution to the stem end of the crop after topping, ensuring even coverage. This design not only ensures precise spraying of the plant, but also optimizes the efficiency of pesticide use, improves the bud suppression effect, and reduces pesticide waste and environmental pollution.

[0043] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0044] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0045] For ease of description, the words "up," "down," "left," and "right" appearing in this invention only indicate that they are consistent with the up, down, left, and right directions of the accompanying drawings themselves. They do not limit the structure and are merely for the purpose of facilitating the description of this invention and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0046] As described in the background section, tobacco buds have multiple degrees of freedom, and mechanized topping and bud suppression requires restricting these degrees of freedom, which is quite difficult. Therefore, currently, tobacco topping and bud suppression in China is mainly done manually, using a two-person operation with one person topping and one person suppressing the bud. Traditional manual bud suppression typically requires six applications, necessitating 6.5 workers per acre, which is labor-intensive and time-consuming. Furthermore, there are problems such as excessive or uneven application of bud suppressant, leading to unsatisfactory bud suppression results and high pesticide costs per acre. To address these issues, this invention proposes a small-scale, multi-functional bud suppression and plant protection machine and method.

[0047] Example

[0048] In a typical embodiment of the present invention, such as Figures 1-7 As shown, a small, multi-functional plant protection machine for suppressing bud growth is proposed. In tobacco topping and bud suppression operations, a GPS navigation system provides accurate location information and navigation guidance, assisting the machine in precise operation in the field. Simultaneously, height recognition radar and positioning radar work together to accurately measure the position of the terminal buds of tall crops. Based on this measurement data, the scissor-type operating platform can automatically adjust the height of the topping and bud suppression device, and the device's horizontal position can be adjusted to ensure the cutting blade is precisely positioned below the 2-4 young leaves below the top inflorescence of the tobacco plant for topping. During topping, a multi-hole, fully conical nozzle evenly sprays the pesticide onto the topping blade, which then applies the pesticide to the stem tip after topping, ensuring precise spraying of the plant. This process is carried out simultaneously with the topping operation, successfully achieving bud suppression.

[0049] This embodiment addresses the problems existing in current topping and bud-suppressing machines by providing a small, multi-functional bud-suppressing plant protection machine. This machine can perform precise topping of tobacco and precise application of bud-suppressing agents in a single operation, and can also perform pesticide spraying. The multi-functional bud-suppressing plant protection machine can perform topping and bud-suppressing operations simultaneously. Because bud suppression is carried out during the topping process, this device significantly improves work efficiency and reduces labor requirements and workload. Furthermore, this machine can also be used independently as a plant protection machine, achieving multiple uses in one machine. This multi-functionality not only improves equipment utilization but also provides assistance in various agricultural production stages, such as pest and disease control and pesticide spraying, thus providing farmers with a more comprehensive and economical solution.

[0050] Furthermore, the device employs a scissor lift platform and sliding rails, adapting to tall crops of varying heights and spacing. This aims to improve the accuracy of topping and bud suppression, reduce spraying costs, and significantly decrease chemical emissions into the environment. Simultaneously, its tracked chassis design enables it to maintain stable traction and mobility in various terrains and environments, including wet, muddy, rugged terrain, and complex areas such as slopes and terraces.

[0051] As the tracked chassis moves along the tobacco plant, positioning and height recognition radars work together to measure the crop's height in real time and transmit this data to the scissor lift platform and sliding rail system. Based on the received signals, this system precisely positions the topping device, ensuring accurate topping of the tobacco's growing point. Simultaneously, multi-hole full-cone nozzles spray a bud-suppressing agent, performing precise topping and bud-suppressing operations, thereby improving operational efficiency and effectiveness.

[0052] This embodiment provides a small-scale bud-suppressing plant protection multi-functional machine, including a tracked chassis 1, a bud-suppressing device 3, a scissor-type lifting platform 2, a firework collection device 4, and a spraying device 5;

[0053] A gantry frame is installed on the tracked chassis 1. A scissor lift platform 2 is installed on the upper part of the gantry frame. The scissor lift platform 2 drives the top-suppressing and bud-suppressing device 3 to rise and fall. A fireworks collection device 4 is installed on the lower part of the gantry frame. A spraying device 5 is installed on the front vertical bar of the gantry frame.

[0054] This small, multi-functional plant protection machine can complete topping and bud suppression operations in one go, greatly improving operational efficiency and reducing the demand for manpower in large-scale operations, thereby promoting the mechanization and large-scale development of the tobacco planting industry. Simultaneously, it can also be used independently as a plant protection machine to perform pesticide spraying, achieving multi-functionality.

[0055] Furthermore, the tracked chassis 1 includes a gantry frame 11, a GPS navigation system 12, a height recognition radar 13, an electrical control cabinet 14, a battery 15, and a range extender 16. The gantry frame 11 securely connects to and supports the tracks on both sides, ensuring the stability and coordinated movement of the entire structure. The GPS navigation system 12 is installed on the top of the gantry frame, ensuring accurate positioning and navigation of the equipment during operation. The height recognition radar 13 is fixed to the front of the gantry frame 11, ensuring real-time monitoring and measurement of the height of the crops in front, providing accurate data support for the topping and bud-suppressing device. The electrical control cabinet 14, battery 15, and range extender 16 are respectively installed on both sides of the gantry frame 11, ensuring the balance and stability of the machine, while facilitating maintenance and repair. The tobacco topping and bud-suppressing machine uses a tracked chassis, which has excellent stability and traction, and can operate smoothly in various terrain conditions, including wet, muddy, rugged ground, as well as slopes and terraces. This design not only improves the machine's maneuverability in complex environments but also ensures the continuity and efficiency of operations, thereby significantly enhancing overall productivity and work quality. Utilizing GPS technology provides precise positioning and navigation, ensuring the machine maintains a clear path while moving through the field; it also records operational trajectories and data, providing farmers with real-time farmland management information to aid in agricultural production decisions and management. This not only improves the accuracy and efficiency of topping and bud suppression but also reduces repetitive work and omissions, optimizes resource utilization, and lowers labor requirements, thus greatly enhancing overall operational productivity and economic benefits.

[0056] Furthermore, the topping and bud-suppressing device 3 includes a positioning radar 31, a topping blade 33, a permanent magnet DC motor 32, a bud-suppressing mechanism, and a base 36. The base 36 is connected to the screw-slider mechanism of the scissor lift platform 2. The permanent magnet DC motor 32 is fixed on the base 36. The positioning radar 31 is installed at both ends of the top of the base 36, and the output shaft of the permanent magnet DC motor 32 passes through the bud-suppressing mechanism and is connected to the topping blade 33. The bud-suppressing mechanism is fixed on the base 36. The height recognition radar 13 and the positioning radar 31 work together to determine the height of the bud at the top of the topping device for tall crops, thereby achieving precise topping operation. Specifically, firstly, the height recognition radar 13 identifies the height of the plant and adjusts the height of the topping and bud-suppressing device 3. Then, the positioning radar 31 on the topping and bud-suppressing device 3 identifies the plant's moving speed and position relative to the machine. Then, by combining the data collected by the two radars, the topping and bud-suppressing device 3 is moved to a suitable position for operation. This cooperation greatly improves the accuracy and efficiency of the topping and bud-suppressing operation, ensuring that each crop is precisely treated.

[0057] First, the plant height and horizontal position are measured. Then, the scissor-type operating platform adjusts the topping and bud-suppressing device 3 to an appropriate height. The topping blade has a "seven"-shaped sheet structure. Driven by a permanent magnet DC motor, the topping blade rotates around its axis to top the tobacco buds. Furthermore, the bud-suppressing mechanism includes two multi-hole full-cone nozzles 34 and a bud-suppressing agent inlet pipe 35. The multi-hole full-cone nozzle 34 consists of seven individual spray holes, which can provide a uniform, round, and full spray pattern, and consists of small-sized droplets. The multi-hole full-cone nozzle 34 is located above the topping blade 33, which can evenly spray the agent onto the top surface of the topping blade 33. Several agent drainage holes are set on the topping blade 33, which can guide the agent to the bottom surface and the blade edge of the topping blade, thereby achieving precise application of the agent to the stem end of the crop after topping while topping.

[0058] The sprout inhibitor input pipe 35 includes a double-layer hollow cylindrical tube and a horizontal input pipe connected to the double-layer hollow cylindrical tube. A multi-hole full-cone nozzle 34 is provided on the horizontal input pipe. The inner and outer walls of the double-layer hollow cylindrical tube form an annular sprout inhibitor input channel, which is connected to the horizontal input pipe to realize the input of the sprout inhibitor. The output shaft of the permanent magnet DC motor passes through the double-layer hollow cylindrical tube and is connected to the top-adhesive blade. Due to the use of the double-layer hollow cylindrical tube, the output shaft of the permanent magnet DC motor does not come into contact with the sprout inhibitor. When the output shaft of the permanent magnet DC motor rotates, it simultaneously drives the sprout inhibitor mechanism to rotate, so that when the top-adhesive blade 33 rotates to other angles, the multi-hole full-cone nozzle 34 can still spray the agent onto the top-adhesive blade 33.

[0059] In this embodiment, the multi-hole full-cone nozzle evenly sprays the pesticide solution onto the topping knife 33. During the topping process, the topping knife 33 precisely applies the pesticide solution to the stem end of the crop after topping, ensuring uniform coverage. This design not only ensures precise spraying of the plant but also optimizes the efficiency of pesticide use, improves the bud suppression effect, and reduces pesticide waste and environmental pollution. In other words, this invention performs topping and bud suppression simultaneously.

[0060] Furthermore, the scissor lift platform 2 includes a scissor arm structure 21, a lifting motor 22, guide wheels 23, a lateral movement motor 24, a lead screw 25, and a slider 26. The scissor lift platform 2 is securely mounted on the upper structure of the gantry frame, providing reliable lifting functionality and a wide operating range. The scissor arm structure 21 is the core mechanical structure of the scissor lift platform, consisting of multiple cross-connected scissor arms. These scissor arms are telescopic; they extend or retract relative to each other as the lifting platform rises or falls, thus achieving the platform's lifting motion. The lifting motor 22 is mounted on the top of the scissor lift platform, directly driving the movement of the scissor arms. The lead screw 25 and slider 26 are the components on the scissor lift platform used to install the top-suppressing device. Connected to the top of the scissor arms, they move up and down with the lifting of the scissor arms, simultaneously enabling the horizontal movement of the top-suppressing device. Specifically, the lateral movement motor 24 drives the lead screw 25 to rotate, which in turn moves the slider 26. The top-suppressing device is mounted on the slider 26, thus achieving its horizontal movement. Guide wheels 23 are installed at key connection points of the scissor arms, ensuring that the scissor arms maintain the correct track and direction during movement.

[0061] The scissor lift platform in this embodiment has several advantages, including its stable scissor arm structure, which provides strong load-bearing capacity and reliable lifting performance. This structural design ensures smooth and safe lifting during the process, making it suitable for work requirements at various heights. Furthermore, the scissor lift platform is easy to operate and has low maintenance costs.

[0062] Furthermore, the fireworks collection device 4 includes a collection guide 41 and a detachable storage box 42; a fireworks collection guide 41 and a detachable storage box 42 are respectively installed on both sides of the gantry to ensure efficient collection of fireworks fragments and facilitate storage and cleaning operations; a small fan is installed inside the fireworks collection guide 41 to efficiently guide the knocked-down buds into the storage box 42, ensuring a smooth and effective collection process;

[0063] The two firework collection guides 41 have openings at the top and are connected to the removable storage box 42 at the bottom. The opening at the top is the entrance for firework fragments. Firework fragments knocked down by the top-hitting knife 33 will enter the removable storage box 42 through this opening. The two firework collection guides 41 are symmetrically arranged below the top-hitting knife 33, with a certain gap between them, to guide the plant so that it can be in an upright position.

[0064] Furthermore, the spraying device 5 includes a spray boom 51 and a pesticide tank 52; a pesticide tank 51 is installed on each side of the gantry to ensure a sufficient supply of pesticide and to make the spraying operation more efficient and continuous. The spray boom 52 is located at the front of the gantry, and two spray booms 52 are provided. One spray boom 52 is located on the front left side of the gantry, and the other spray boom 52 is located on the front right side of the gantry. One spray boom 52 corresponds to one pesticide tank 51. Therefore, two rows of crops can be sprayed at the same time in one operation, which improves the spraying efficiency and operation speed.

[0065] Based on the aforementioned small-scale bud-suppressing plant protection multi-functional machine, a method for precise topping and bud-suppressing of tobacco is also provided, utilizing the precise topping and bud-suppressing device described above, including the following steps:

[0066] (1) GPS navigation system provides accurate location information and navigation guidance to help machinery carry out precise operations in the field.

[0067] (2) The high-altitude identification radar and the positioning radar work together to accurately measure the position of the apical bud of tall crops;

[0068] (3) Based on the data measured by the height identification radar and the positioning radar, the scissor-type operating platform automatically adjusts the height of the topping and bud-suppressing device, and the topping and bud-suppressing device can be adjusted in horizontal position so that the cutting blade is located below 2-4 young leaves under the top inflorescence of the tobacco and topping is carried out.

[0069] (4) During topping, the multi-hole full-cone nozzle evenly sprays the pesticide onto the upper surface of the topping blade, then the pesticide flows to the lower surface, and then contacts the stem tip of the crop from the blade and the lower surface, applying the pesticide to the topped stem tip. The pesticide flows continuously from the blade to the stem, ensuring precise spraying of the plant. This process is carried out simultaneously with the topping operation, realizing the bud suppression operation of the plant.
