Description

Technical Field

[0001] The utility model relates to the technical field of weeders, in particular to an intelligent weeder. Background Art

[0002] A lawn mower, also known as a lawn mower, lawn trimmer, lawn trimmer, etc., is a mechanical tool used to trim lawns, vegetation, etc. It is widely used because it brings great convenience to weeding work in gardening, agriculture or home greening.

[0003] After searching, the patent with patent announcement number CN208509611U discloses a lawn mower. Although the device transmits information to the controller through a wireless communication module when in use, and the controller controls the lawn mower to clean up the broken grass according to the control instructions, the device needs manual remote control to clean up the weeds when in use, which is inefficient and easy to damage vegetables. At the same time, manual identification of vegetable crops and weeds for a long time is easy to cause visual fatigue, resulting in missing weeds, which affects the weed cleaning efficiency. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an intelligent weeder, which solves the problems raised in the background technology.

[0005] The utility model solves the above-mentioned technical problems as follows:

[0006] An intelligent weeder comprises a body, on which a weeding mechanism is installed;

[0007] The vehicle body is provided with a mounting plate, a spraying mechanism is installed at one end of the vehicle body away from the weeding mechanism, a storage tank is installed on the vehicle body below the mounting plate, the storage tank is connected to the spraying mechanism, a control box is installed on the mounting plate, and a second visual recognition camera and a first visual recognition camera are installed on both ends of the mounting plate respectively;

[0008] A servo motor is installed at the bottom end of the vehicle body, a wheel is installed at the output end of the servo motor, and the wheels on the same side of the vehicle body are connected through a crawler drive.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, a through hole is formed on the mounting plate, and the weeding mechanism and the spraying mechanism are installed on the vehicle body through the through hole of the mounting plate.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] By drilling through holes in the design mounting plate and allowing the weeding mechanism and the spraying mechanism to pass through these holes and be installed on the vehicle body, the overall occupied space of the equipment can be significantly reduced. This compact structural design helps to reduce the manufacturing cost and transportation cost of the equipment, while improving the portability and flexibility of the equipment.

[0013] Furthermore, the spraying mechanism is provided with a support column, the top end of the support column is installed with a first rotating seat, the support column is rotatably installed with a spray head through the first rotating seat, a connecting pipe is connected to the spray head, a connecting head is provided at the end of the connecting pipe away from the spray head, and the connecting pipe is communicated with the storage tank through the connecting head.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] The spray head is installed at the top end of the support column through the first rotating seat. This design enables the spray head to rotate freely within a certain range. This flexibility allows the spray head to adjust the spraying angle and direction according to the operation requirements, so as to achieve precise spraying on different areas or at different heights. Since the spray head can rotate, it can better cover the spraying area and avoid forming spraying blind spots. At the same time, the uniform spraying ability of the spray head helps the uniform distribution of pesticides or fertilizers and improves the spraying effect.

[0016] Furthermore, the weeding mechanism is provided with a turntable, the bottom end of the turntable is installed with a rotating seat, a first bracket is movably installed above the turntable, a second bracket is installed on the first bracket, a machine head is installed at the end of the second bracket away from the first bracket, and a auger is installed at the output end of the machine head.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The auger output by the machine head directly breaks the roots of weeds. This design can penetrate into the soil and directly act on the roots of weeds, thus effectively preventing the regeneration of weeds. Compared with the weeding method that only cuts the above-ground part of weeds, this design can more thoroughly remove weeds. And while the auger breaks the roots of weeds, it will also turn and loosen the soil to a certain extent, which helps to improve the air permeability and water retention of the soil and promote soil health. The design of the first bracket and the second bracket allows the machine head to be adjusted in multiple directions to adapt to different terrains and weed growth conditions. This flexibility enables the weeding mechanism to more accurately locate and handle weeds.

[0019] Furthermore, an auxiliary camera is installed at the end of the second bracket and below the machine head to assist in positioning the vegetable crops and weeds.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] The auxiliary camera can capture and transmit image information of weeds in real time, providing precise location data for the weeding mechanism. This enables the head to locate weeds more accurately, especially those hidden among vegetable crops or difficult to be found by the naked eye. Through precise positioning, the weeding mechanism can only operate on weeds, avoiding accidental damage to surrounding crops, thereby protecting the growth of crops. The auxiliary camera has the ability to quickly identify vegetable crops and weeds, and can locate a large number of vegetable crops and weeds in a short time. This greatly shortens the time the weeding mechanism spends searching for weeds and improves overall operating efficiency. Combining the positioning information of the intelligent navigation system and the auxiliary camera, the weeding mechanism can plan the optimal weeding path, reduce repeated operations and ineffective movements, and further improve operating efficiency.

[0022] Furthermore, the rotating seat is mounted on the vehicle body, and the turntable is located in the through hole of the mounting plate.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] The design of mounting the rotating seat on the vehicle body and placing the turntable in the through hole of the mounting plate maximizes the use of space and makes the entire mechanism more compact. This helps to reduce the overall size and weight of the device, improving the portability and flexibility of the device. By directly embedding the turntable in the through hole of the mounting plate, the need for additional connectors or support structures can be reduced, thereby simplifying the design and production process of the device.

[0025] Furthermore, a first joint motor is installed on the turntable, the first bracket is installed at the output end of the first joint motor, the first bracket is rotated by the first joint motor, a second joint motor is installed at the connection between the first bracket and the second bracket, the second bracket is transmission connected to the output end of the second joint motor, and the second bracket is rotated by the second joint motor.

[0026] The beneficial effects of adopting the above further scheme are:

[0027] The design of two joint motors enables the independent rotation of the first bracket and the second bracket. This design enables the weeding mechanism to be flexibly adjusted within a wider range to adapt to different terrains and weed growth conditions. The coordinated work of the first joint motor and the second joint motor provides the weeding mechanism with multiple degrees of freedom control. This helps to achieve more precise operation path and angle adjustment, and improve the accuracy and efficiency of weeding. The precise control of the joint motor enables the weeding mechanism to accurately aim at vegetable crops and weeds for precise operation. This helps to reduce the possibility of accidental damage to surrounding crops and ensure the maximum weeding effect.

[0028] The utility model provides an intelligent weeder, which has the following beneficial effects:

[0029] The second joint motor and the first joint motor installed on the first bracket and the second bracket achieve multi-degree-of-freedom adjustment of the weeding mechanism (especially the machine head and the auger). This flexibility enables the weeding machine to accurately align and remove weeds at various positions and angles, improving the efficiency and accuracy of weeding.

[0030] The installed first and second visual recognition cameras not only enhance the autonomous navigation ability of the device but also can be used to monitor crop growth conditions, weed distribution, etc., providing data support for precision agriculture. The equipped auxiliary camera can assist in positioning vegetable crops and weeds. Combining image recognition technology can further improve the accuracy of weeding and reduce the possibility of accidentally damaging non-target plants.

[0031] The spraying mechanism is installed on the pillar through the first rotating seat, allowing the nozzle to rotate within a certain range. This helps to achieve more uniform and extensive spraying operations. Especially when spraying pesticides or fertilizers after local weeding is required, it can significantly improve the operation effect.

[0032] The wheels and track drive system driven by servo motors ensure the stable movement and efficient operation of the weeding machine on complex terrains. The track design enhances the passability and grip of the device, especially suitable for uneven or slippery fields. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] Please refer to Figures 1 to 4 as shown, the embodiments provided by the present invention are as follows:

[0043] Embodiment 1

[0044] An intelligent weeder includes a vehicle body 5, on which a weeding mechanism 1 is installed. The weeding mechanism 1 is provided with a turntable 107, on which a first joint motor 109 is installed. A first bracket 101 is installed at the output end of the first joint motor 109, and the first bracket 101 is driven to rotate by the first joint motor 109. A second joint motor 102 is installed at the connection between the first bracket 101 and the second bracket 103, and the second bracket 103 is connected to the output end of the second joint motor 102 by transmission, and the second bracket 103 is driven to rotate by the second joint motor 102. Through the design of two joint motors, the first bracket 101 and the second bracket 103 are independently rotated. This design enables the weeding mechanism 1 to be flexibly adjusted in a wider range to adapt to different terrains and weed growth conditions. The coordinated work of the first joint motor 109 and the second joint motor 102 provides the weeding mechanism 1 with multiple degrees of freedom control. This helps to achieve more accurate operation path and angle adjustment, and improve the accuracy and efficiency of weeding. The precise control of the joint motor enables the weeding mechanism 1 to accurately aim at the weeds and achieve precise operation. This helps to reduce the possibility of accidental damage to surrounding crops and ensure the maximization of the weeding effect. The bottom end of the turntable 107 is equipped with a rotating seat 108, which is installed on the vehicle body 5, and the turntable 107 is located in the through hole of the mounting plate 501. The rotating seat 108 is installed on the vehicle body 5, and the turntable 107 is placed in the through hole of the mounting plate 501. This design maximizes the use of space and makes the entire mechanism more compact. This helps to reduce the overall size and weight of the device and improve the portability and flexibility of the device. By directly embedding the turntable 107 into the through hole of the mounting plate 501, the need for additional connectors or supporting structures can be reduced, thereby simplifying the design and production process of the equipment. A first bracket 101 is movably installed above the turntable 107, a second bracket 103 is installed on the first bracket 101, a head 104 is installed at one end of the second bracket 103 away from the first bracket 101, and an auxiliary camera 106 is installed at the end of the second bracket 103 below the head 104. The auxiliary camera 106 is used to assist in positioning vegetable crops and weeds. The auxiliary camera 106 can capture and transmit image information of vegetable crops and weeds in real time, and provide accurate location data for the weeding mechanism 1. This enables the head 104 to more accurately locate vegetable crops and weeds, especially those weeds hidden between crops or difficult to be found by the naked eye. Through precise positioning, the weeding mechanism 1 can only operate on weeds, avoiding accidental damage to surrounding crops, thereby protecting the growth of crops. The auxiliary camera 106 has the ability to quickly identify weeds and can locate a large number of vegetable crops and weeds in a short time, which greatly shortens the time the weed removal mechanism 1 spends on finding weeds and improves the overall operating efficiency.Combined with the positioning information of the intelligent navigation system and the auxiliary camera 106, the weeding mechanism 1 can plan the optimal weeding path, reduce repeated operations and ineffective movements, and further improve the work efficiency. The output end of the head 104 is equipped with an auger 105, and the auger 105 output by the head 104 directly breaks the weed roots. This design can penetrate into the soil and directly act on the roots of the weeds, thereby effectively preventing the weeds from regenerating. Compared with the weeding method of only cutting the above-ground part of the weeds, this design can remove the weeds more thoroughly. In addition, while the auger 105 breaks the weed roots, it will also turn and loosen the soil to a certain extent, which helps to improve the air permeability and water retention of the soil and promote the health of the soil. The design of the first bracket 101 and the second bracket 103 enables the head 104 to be adjusted in multiple directions to adapt to different terrains and weed growth conditions. This flexibility enables the weeding mechanism 1 to more accurately locate and process weeds, and a mounting plate 501 is provided on the vehicle body 5.

[0045] Embodiment 2

[0046] In order to facilitate the spraying of herbicides on the area after preliminary weeding, and locate the weeds by visual recognition equipment, for example, Figures 1 to 4As shown in the figure, the present invention further includes: a spraying mechanism 3 is installed at one end of the vehicle body 5 away from the weeding mechanism 1. The spraying mechanism 3 is provided with a support column 305. At the top of the support column 305, a first rotating seat 302 is installed. The support column 305 is rotatably installed with a nozzle 301 through the first rotating seat 302. A connecting pipe 303 is connected to the nozzle 301. At the end of the connecting pipe 303 away from the nozzle 301, a connector 304 is provided. The connecting pipe 303 is connected to the storage tank 6 through the connector 304. The nozzle 301 is installed at the top of the support column 305 through the first rotating seat 302. This unique design enables the nozzle 301 to rotate freely and flexibly within a certain range. This flexibility allows the nozzle 301 to easily adjust the spraying angle and direction according to specific operation requirements, thereby achieving precise spraying on different areas or at different heights. Since the nozzle 301 can rotate freely, it can better cover the spraying area and effectively avoid the formation of spraying blind spots. At the same time, the uniform spraying ability of the nozzle 301 helps to ensure the uniform distribution of pesticides or fertilizers in the target area, thus significantly improving the spraying effect. Through holes are formed through the mounting plate 501, and the weeding mechanism 1 and the spraying mechanism 3 are installed on the vehicle body 5 through the through holes of the mounting plate 501. When designing the mounting plate 501, by forming through holes and allowing the weeding mechanism 1 and the spraying mechanism 3 to pass through these through holes and be installed on the vehicle body 5, such a design can significantly reduce the overall occupied space of the equipment. This compact structural design has multiple advantages. It not only helps to reduce the manufacturing cost and transportation cost of the equipment, but also significantly improves the portability and flexibility of the equipment. A storage tank 6 is installed below the mounting plate 501 on the vehicle body 5. The storage tank 6 is connected to the spraying mechanism 3. A control box 2 is installed on the mounting plate 501. The control box 2 is responsible for receiving instructions from the operator or the automation system. By precisely controlling the rotation speed, steering, and torque of the servo motor 504, the first joint motor 109, and the second joint motor 102, it realizes the driving of the wheels 502, the rotation of the turntable 107, and the flexible rotation of the first bracket 101 and the second bracket 103 in the weeding mechanism 1. The control box 2 also controls the operation of the spraying mechanism 3, including the opening and closing of the nozzle 301, the adjustment of the spraying angle, etc., to ensure that pesticides or water can be accurately and evenly sprayed onto the target area. The control box 2 receives the image data from the first vision recognition camera 7, the second vision recognition camera 4, and the auxiliary camera 106, and performs weed recognition, positioning, and target tracking through the built-in image processing algorithm. According to the processing results, the control box 2 can issue instructions to adjust the working states of the weeding mechanism 1 and the spraying mechanism 3. The second vision recognition camera 4 and the first vision recognition camera 7 are respectively installed at both ends of the mounting plate 501.

[0047] Embodiment III

[0048] For the convenience of equipment movement, exemplarily, such as Figures 1 to 4As shown in the figure, the present invention further includes: a servo motor 504 is installed at the bottom end of the vehicle body 5, a wheel 502 is installed at the output end of the servo motor 504, and the wheels 502 on the same side of the vehicle body 5 are drivingly connected through a crawler 503. The crawler 503 is designed to increase the contact area between the wheel 502 and the ground, improving the vehicle's grip. This is particularly important for driving on soft, muddy or uneven ground, which can reduce slipping and ensure the vehicle moves forward stably. The crawler 503 vehicle can easily cross obstacles such as ditches and stones without the worry of getting stuck or blocked like a wheeled vehicle. This passability makes the crawler 503 vehicle more flexible and reliable in complex terrains. Using the servo motor 504 as the power source can achieve precise control of the rotational speed and steering of the wheel 502. The servo motor 504 has the advantages of fast response speed, accurate positioning, and stable operation, which can ensure the vehicle maintains a stable posture and trajectory during driving.

[0049] Working principle:

[0050] By integrating a variety of sensors (such as the auxiliary camera 106, visual recognition camera) and motor drive systems (such as the first joint motor 109, second joint motor 102, servo motor 504), the intelligentization and automation of the weeding and spraying operations are realized. This greatly reduces the burden of manual operation and improves the operation efficiency and accuracy.

[0051] The multi-degree-of-freedom adjustment ability of the weeding mechanism 1 enables the machine to accurately align and remove weeds at various positions and angles. At the same time, the addition of the auxiliary camera 106 further improves the accuracy of vegetable crop and weed positioning, reducing the possibility of accidentally damaging non-target plants.

[0052] The wheels 502 driven by the servo motor 504 and the crawler 503 drive system ensure the efficient movement of the weeding machine during operation. At the same time, the flexible rotation design of the spraying mechanism 3 helps to achieve a more uniform and extensive spraying operation, improving the utilization rate of pesticides or fertilizers.

[0053] The visual recognition camera can not only be used for vegetable crop and weed positioning, but may also be used to monitor the crop growth status, weed distribution, etc., providing valuable data support for precision agriculture. These data help farmers or farm managers make more scientific decisions and optimize the agricultural production process.

[0054] The foregoing has shown and described the basic principles, main features and advantages of the present invention. For a person skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
