Description

Technical Field

[0001] This invention relates to the field of young forest tending equipment, specifically a weeding device for tending young and middle-aged forests. Background Technology

[0002] Young and middle-aged forest tending is a crucial aspect of forestry management. Weeding directly impacts the growth environment and efficiency of these forests. Precise and efficient weeding and soil loosening operations are necessary, especially considering the common 0.6-1.5 meter row spacing variations among young and middle-aged forests. Currently, weeding devices used for young and middle-aged forest tending have become essential tools in forestry production. Their core requirements are adaptability to weeding areas of varying widths, ensuring stability and precision in weeding and soil loosening, while also considering portability and ease of operation. This is to meet the needs of small-scale and meticulous young and middle-aged forest tending operations, reduce manual labor intensity, and improve overall tending efficiency.

[0003] Existing weeding devices used for tending young and middle-aged forests generally have difficulty adapting to weeding areas of varying widths within these areas, resulting in poor operational flexibility. They typically only adapt to a single, fixed-width weeding area, requiring frequent manual adjustments and cumbersome operation. Furthermore, they lack intelligent surveying and control mechanisms, relying on manual observation to determine the width of the weeding area, leading to low operational precision and high levels of human intervention. Consequently, weeding efficiency is low, failing to meet the demands for refined and efficient tending of young and middle-aged forests. Therefore, there is an urgent need to develop a weeding device for tending young and middle-aged forests to overcome the shortcomings in current practical applications. Summary of the Invention

Detailed Implementation

[0052] 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.

[0053] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0054] Please see Figures 1-11 The present invention provides a weeding device for tending young and middle-aged forests, including a weeding handle 1 (made of carbon fiber, 1.0-1.3 meters in length, weighing ≤2 kg, for easy gripping and operation), and further including:

[0055] The width and narrow weeding control body 8 is fixedly connected to the weeding handle 1 by bolts. The width and narrow weeding control body 8 is provided with a width and narrow adjustment chamber 23. The width and narrow adjustment chamber 23 is fitted with two telescopic control columns 12 (made of aluminum alloy, with a length that can be extended and retracted within the range of 30-60cm, and a wear-resistant coating with a thickness of 0.08-0.15mm). The two telescopic control columns 12 are slidably connected to the width and narrow adjustment chamber 23 through linear slide rails.

[0056] A drive assembly with a shift function is connected to the weeding handle 1;

[0057] The weeding adjustment moving belt 7 is sleeved on the two telescopic control columns 12 and the belt moving drive assembly, forming a shape that can follow the contraction and extension trajectory of the telescopic control columns 12. The weeding adjustment moving belt 7 is made of high-strength hard rubber material, with a thickness of 1.2-1.6cm and a width of 8-12cm, and the surface is provided with anti-slip texture.

[0058] The weeding adjustment moving belt 7 is evenly equipped with multiple weeding and loosening teeth 11 (made of 65Mn manganese steel, with a thickness of 0.6-0.8cm, a length of 4-6cm, a spacing of 6-10cm between two adjacent weeding and loosening teeth 11, and a tip angle of 30-45°, to facilitate soil loosening).

[0059] The system includes a weeding controller 9 (using an STM32F030 series microcontroller as the core control unit, with a power supply voltage of 12V, an operating current of 40-80mA, and a signal transmission distance of ≤30m). The weeding controller 9 is bolted to the width and narrowness weeding control body 8 and is connected to the width and narrowness weeding control body 8 and the belt-moving drive assembly via a CAN bus signal. It controls the width and narrowness weeding control body 8 to move the two telescopic control columns 12 according to the width of the weeding area, and simultaneously controls the belt-moving drive assembly to change the shape of the weeding adjustment moving belt 7, ultimately achieving adaptive weeding operation for weeding areas of different widths from 0.6 to 1.5 meters.

[0060] Given the limitations of existing weeding devices for young and middle-aged forests, which often struggle to adapt to row spacing differences of 0.6-1.5 meters and lack operational flexibility (typically only adapting to a single row spacing), this invention addresses these issues. The weeding controller 9, based on an STM32F030 microcontroller, first receives the width data of the working area transmitted by the detection device 20. Combining this with preset row spacing standards for young and middle-aged forests, it sends control commands to the width-width weeding control body 8. This causes the two telescopic control columns 12 within the width-width adjustment chamber 23 to slide along a linear guide rail, achieving telescopic movement within a 30-60cm range, thereby adjusting the weeding width to 0.6-1.5 meters. Simultaneously, the weeding controller 9 synchronously controls the belt-moving drive component via a CAN bus, enabling the belt-moving drive component to move within the two telescopic control columns... The high-strength rubber weeding adjustment moving belt 7 on the control column 12 and the belt drive assembly can accurately follow the movement trajectory of the telescopic control column 12 to change shape, ensuring that the weeding adjustment moving belt 7 always remains taut (tension controlled at 8-12N). The 65Mn manganese steel weeding and loosening teeth 11 (spacing 6-10cm) evenly distributed on the weeding adjustment moving belt 7 achieve weeding and loosening operations with a depth of 4-6cm as the moving belt is driven (linear speed 0.2-0.6m / s). Ultimately, it achieves adaptive coverage weeding for weeding areas of different widths or special weeding areas, effectively improving the targeting and operational efficiency of weeding in young and middle-aged forest tending, and solving the drawbacks of traditional devices that require frequent manual adjustments and have low operational efficiency.

[0061] In one embodiment of the present invention, please refer to Figures 1-11 A reinforcing baffle 10 (made of stainless steel, with a thickness of 1.5-2.5mm and a length consistent with the width and narrowness weed control body 8) is fixedly installed on the wide and narrow weed control body 8 by welding. A reinforcing groove (with a width of 1.3-1.8cm) is formed between the reinforcing baffle 10 and the width and narrowness weed control body 8.

[0062] The weeding adjustment moving belt 7 is fitted into the reinforcing slot to limit and reinforce the weeding and loosening teeth 11 used for weeding, preventing the loosening teeth from shifting laterally during operation.

[0063] It also includes: a rotating groove 19 (located at the end of the telescopic control column 12), in which a control guide wheel 16 (made of engineering plastic, with an outer rubber layer, a diameter of 11-15cm and a thickness of 1.3-1.8cm) is rotatably mounted via a bearing.

[0064] The weeding adjustment moving belt 7 is sleeved on the control guide wheel 16 to support and guide the weeding adjustment moving belt 7 and reduce the driving resistance of the moving belt (resistance ≤ 2.5N).

[0065] Please see Figures 1-11The thickness of the weeding and loosening teeth 11 (0.6-0.8cm) is less than the thickness of the weeding adjustment and moving belt 7 (1.2-1.6cm), and multiple weeding and loosening teeth 11 are arranged close to the outer surface of the weeding adjustment and moving belt 7 to ensure that the loosening teeth can fully contact the roots of weeds.

[0066] A sliding baffle 24 (made of stainless steel, 1.2-1.8mm thick, and 0.8-1.2cm larger in diameter than the control guide wheel 16) is fixedly installed on the control guide wheel 16 to limit the upper and lower sides of the weeding adjustment moving belt 7.

[0067] The length of the sliding baffle 24, which is half the diameter difference between the control guide wheel 16, is D (0.4-0.6cm). D is less than the thickness of the weeding adjustment moving belt 7 (1.2-1.6cm) and less than the thickness difference between the thickness of the weeding adjustment moving belt 7 and the thickness of the weeding loosening teeth 11 (0.4-0.8cm).

[0068] And a corner guardrail 15 (stainless steel material, thickness 1.2-1.8mm, length consistent with the height of the control guide wheel 16), the corner guardrail 15 is fixedly installed on the telescopic control column 12 by welding, and forms a guide groove (width 0.9-1.1cm, depth 1.5-2.5cm) with the sliding baffle 24 to limit the outer side of the weeding adjustment moving belt 7;

[0069] The width of the guide groove is greater than the thickness of the weeding and loosening teeth 11, ensuring that the loosening teeth can extend smoothly during operation.

[0070] In this invention, the stainless steel reinforcing baffle 10 (1.5-2.5mm thick) on the wide and narrow weeding control main body 8 forms a 1.3-1.8cm wide reinforcing groove with the main body, in which the weeding adjustment moving belt 7 is fitted, effectively limiting and reinforcing the weeding and loosening teeth 11 installed on the moving belt, controlling the lateral offset of the loosening teeth within ±0.3cm; the control guide wheel 16, which is rotatably installed in the rotating groove 19 at the end of the telescopic control column 12 via a bearing, provides a stable support point for the weeding adjustment moving belt 7, while the rubber outer layer reduces the frictional resistance during the moving belt transmission; because the thickness of the weeding and loosening teeth 11 is less than the thickness of the weeding adjustment moving belt 7 and is set close to the outer side of the moving belt (0.15-0.25cm away), it is ensured that the loosening teeth can fully engage. Effective weeding is achieved by touching the roots of weeds. The sliding baffle 24 on the control guide wheel 16 limits the upper and lower sides of the weeding adjustment moving belt 7, and the D value is less than the thickness of the weeding adjustment moving belt 7 and the thickness difference between the moving belt and the loosening teeth. This prevents the moving belt from detaching from the guide wheel and does not affect the normal operation of the loosening teeth. The 0.9-1.1cm wide guide groove formed by the bend of the corner guard 15 on the telescopic control column 12 and the sliding baffle 24 limits the outer side of the moving belt. The width of the guide groove is greater than the thickness of the weeding loosening teeth 11, ensuring that the loosening teeth can smoothly extend out of the groove for weeding. The cooperation of each component significantly improves the stability of the transmission of the weeding adjustment moving belt 7 and the accuracy of the operation of the weeding loosening teeth 11, avoiding the problem of poor weeding effect caused by loosening or offset of components.

[0071] In one embodiment of the present invention, please refer to Figures 1-11 The belt-driven component includes:

[0072] Telescopic storage compartment 3 (set on the weeding handle 1, with a length of 40-60cm), the telescopic storage compartment 3 is set on the weeding handle 1;

[0073] The movable telescopic component 4 (using an electric push rod, model DTZ200, with a stroke of 20-40cm, a thrust of 300-500N, and a telescopic speed of 5-10mm / s) is fixedly installed in the telescopic storage compartment 3 by bolts, and a bracket 5 (aluminum alloy material, with a load-bearing capacity of not less than 30kg) is fixedly installed on the output end of the movable telescopic component 4 by bolts.

[0074] And a movable wheel 18 (made of engineering plastic with an outer rubber layer, with a diameter of 12-16cm and a thickness of 1.3-1.8cm), the movable wheel 18 being rotatably mounted on the bracket 5 via bearings;

[0075] The weeding adjustment moving belt 7 is fitted onto the moving wheel 18.

[0076] Please see Figures 1-11It also includes: a limiting baffle 6 (made of stainless steel, with a thickness of 1.2-1.8mm and a diameter 0.8-1.2cm larger than the moving wheel 18), the limiting baffle 6 being fixedly installed on the moving wheel 18, used to limit the upper and lower sides of the weeding adjustment moving belt 7;

[0077] The sliding protrusion 21 (made of aluminum alloy, with a width of 3-4cm, a height of 1.5-2.5cm, and a length of 8-12cm) is fixedly installed on the limiting baffle 6 by welding.

[0078] And a sliding groove 22 (set inside the telescopic storage compartment 3, with a width of 3.1-4.1cm, a depth of 1.6-2.6cm, and a length of 40-60cm), wherein the sliding groove 22 is set inside the telescopic storage compartment 3, wherein the sliding protrusion 21 is fitted into the sliding groove 22 and is slidably connected to the sliding groove 22 by a slider (sliding resistance ≤4N).

[0079] Please see Figures 1-11 It also includes: a guide wheel 13 (made of engineering plastic, with a rubber layer on the surface, 0.4cm thick, 10-13cm in diameter, and 1.3-1.8cm thick), the guide wheel 13 is rotatably mounted on the weeding handle 1 through bearings, and is in contact with the outer side of the weeding adjustment moving belt 7 (the contact pressure is 1.5-2.5N), used to guide the weeding adjustment moving belt 7.

[0080] In this invention, the belt-driven component provides installation space through the telescopic storage compartment 3 on the weeding handle 1. The telescopic component 4 is fixed inside the telescopic storage compartment 3 and drives the aluminum alloy bracket 5 to drive the moving wheel 18 to achieve telescopic movement. This allows the weeding adjustment moving belt 7, which is sleeved on the moving wheel 18, to adjust its tension (tension 8-12N) according to the movement of the telescopic control column 12, ensuring that the moving belt always maintains a stable transmission state. (The moving wheel 18 can also be equipped with a motor, which can drive the weeding adjustment moving belt 7 to move, thereby changing the position of the weeding and loosening teeth 11. It can be used with an air blowing device to clean and maintain the teeth, but this will not be described in detail here.)

[0081] The stainless steel limiting baffle 6 on the moving wheel 18 limits the upper and lower sides of the weeding adjustment moving belt 7 to prevent the moving belt from moving up and down during transmission. The aluminum alloy sliding protrusion 21 on the limiting baffle 6 is engaged in the sliding groove 22 in the telescopic storage compartment 3 and is connected by a slider, which can guide the bracket 5 and the moving wheel 18 to move along a fixed track and avoid lateral deviation. At the same time, the guide wheel 13 rotatably mounted on the weeding handle 1 fits tightly against the outer side of the weeding adjustment moving belt 7, further correcting the transmission direction of the moving belt and controlling the transmission direction deviation within ±0.4cm. This reduces frictional wear between the moving belt and other components, extends the service life of the moving belt, and ensures that the weeding adjustment moving belt 7 can achieve smooth and precise transmission in different telescopic states, thereby improving the overall durability and operational stability of the device.

[0082] In one embodiment of the present invention, please refer to Figures 1-11 It also includes: a survey support 17 (aluminum alloy material, height 12-16cm, base area 8×8cm), the number of the survey support 17 is 2-3, and the 2-3 survey support 17 are evenly fixedly installed on the wide and narrow weed control body 8 (spacing 20-30cm).

[0083] Each of the survey supports 17 is equipped with a detection device 20 (using a GP2Y0A02YK infrared ranging sensor, with a measurement range of 0.1-5m, a measurement accuracy of ±1cm, and a response time of ≤40ms) fixedly mounted on it by bolts. The detection device 20 is connected to the weeding controller 9 via an RS485 bus signal to transmit data on the width of the working area in real time.

[0084] Please see Figures 1-11 It also includes: a power control system 2 (which can be a pneumatic control system or an electric control system; the pneumatic system includes a solenoid valve of model 4V110-06 and an air pump with a pressure of 0.5-0.7MPa; the electric system includes a servo motor of model MS1H1-06B30CB and a matching driver). The power control system 2 is connected to the wide and narrow weeding control body 8 and the belt-driven drive assembly through air pipes or wires, and is connected to the weeding controller 9 through a CAN bus signal. The power control system 2 is also connected to an external power source through a through hole 14 on the weeding handle 1 to provide stable power to the device.

[0085] In this invention, 2-3 aluminum alloy survey supports 17 are evenly fixed on both sides of the wide and narrow weeding control body 8. Each survey support 17 has a GP2Y0A02YK infrared ranging sensor that can collect key data such as the width of the weeding area and the density of weeds in real time. The collected raw data is sent to the weeding controller 9 via an RS485 bus. The weeding controller 9 has a built-in PID control algorithm that filters, analyzes, and processes the raw data transmitted by the detection device 20. Combined with preset weeding parameters for young and middle-aged forest tending (row spacing 0.6-1.5 meters, weeding depth 4-6 cm), it generates precise control commands for the wide and narrow weeding control body 8 and the drive assembly, while simultaneously sending a power adjustment signal to the power control system 2. The power control system 2 can be implemented using either pneumatic or electric methods. The pneumatic system uses a 4V110-06 solenoid valve to control a 0.5-0.7MPa air pump to output power, while the electric system uses an MS1H1-06B30CB servo motor. The motor and drive provide power. The power control system 2 connects to an external power source (220V AC or ≥3kW diesel generator) through a 1.5-2.5cm diameter through hole 14 on the weeding handle 1. It converts the external power into a power form suitable for the operation of the device (pneumatic pressure 0.5-0.7MPa or electric power 1.0-2.0kW). This provides stable power support for the movement of the telescopic control column 12 driven by the width and narrow weeding control body 8, and for the telescopic and moving belt drive components to achieve telescopic and moving belt drives. It can also adjust the power output and speed in real time according to the instructions of the weeding controller 9 to ensure that the width and narrow adjustment, moving belt drive and other actions are coordinated and synchronized (response time ≤180ms). This enables intelligent and precise weeding operations without manual intervention, with a weeding depth accuracy of ±0.4cm. It significantly improves the operation efficiency (0.8-1.0 hectares / hour) and weeding quality of young and middle-aged forest tending, and solves the problems of high dependence on manual labor and inconsistent operation results of traditional devices.

[0086] In summary, this invention achieves high efficiency, precision, and intelligence in weeding operations for young and middle-aged forests through the organic combination of a width-adaptive adjustable structure, multi-limit reinforcement design, intelligent surveying and control, and a multi-mode power supply system. The weeding width of the device can be flexibly adjusted within the range of 0.6-1.5 meters, adapting to the 0.6-1.5 meter row spacing differences in young and middle-aged forests, increasing the operating efficiency to 0.8-1.0 hectares / hour, 1.5-2 times higher than traditional devices. The weeding and loosening teeth have high positioning accuracy (offset ≤ ±0.3cm) and precise weeding depth control (±0.4cm), effectively ensuring weeding quality. Simultaneously, the device adopts a lightweight design (overall weight 10-15kg), and the power system supports both pneumatic and electric power, adapting to different operational scenarios. It is highly practical and versatile, meeting the actual needs of small-scale, refined young and middle-aged forest tending operations.
