Description

Technical Field

[0002] Due to the continuous growth of the world's population, desertification and irrational use of land, the area of ​​arable land is constantly decreasing. Therefore, only by increasing the yield per unit area of ​​land and reducing the losses caused by weeds can we rely on limited land to feed the growing population, which puts higher requirements on human resources and agricultural weeding equipment. According to statistics from relevant experts at home and abroad, weeds cause losses of up to 95 billion US dollars in global food production each year, which shows the importance of efficient and accurate weeding.

[0003] In the relevant technologies, weed control mainly relies on chemical and physical methods. Chemical weed control is widely used for its fast, efficient, stable effect and labor-saving characteristics, but long-term excessive use of herbicides will cause land pollution and ecological damage. Guguo mainly adopts a coordinated method of physical weed control as the main method and chemical weed control as the auxiliary method. In physical weed control, especially mechanical weed control, it can loosen the soil while weeding, improve soil aeration and permeability, and help improve soil structure. With the development of modern agricultural technology, the wide-narrow row planting model has gradually become an advanced cultivation method to increase crop yields. This model improves crop yields by optimizing the spatial layout of crop plants. Crop plants are usually planted in multiple rows in parallel. Most existing mechanical weeding equipment can usually only remove weeds between rows, but it is difficult to effectively deal with weeds between plants in the row.

DETAILED DESCRIPTION

[0015] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0016] Figure 1 It is a three-dimensional structural schematic diagram of one side of an intelligent weeding device with synergistic effect of machine and pesticide provided by an embodiment of the present invention; Figure 2 It is a schematic diagram of the three-dimensional structure of the other side of an intelligent weeding device with synergistic effect of machinery and pesticides provided by an embodiment of the present invention; Figure 3 It is a schematic diagram of the structure of the cooperation between the frame and a single weeding mechanism provided by an embodiment of the present invention; Figure 4 is a structural schematic diagram of one side of a weeding mechanism provided by an embodiment of the present invention; Figure 5 is a structural schematic diagram of the other side of the weeding mechanism provided by an embodiment of the present invention; Figure 6 is a schematic structural diagram of a row support provided by an embodiment of the present invention; Figure 7 is a schematic structural diagram of a terminal pipe rack provided by an embodiment of the present invention; Figure 8 This is a schematic diagram of the working condition when there are no discrete crops between rows when the intelligent weeding device with coordinated action of machinery and pesticide provided by an embodiment of the present invention is working; Fig. 9 Schematic diagram of the working condition of the intelligent weeding device with synergistic effect of machinery and pesticide provided by the embodiment of the present invention when there are discrete crops between rows. Figures 1 to 9 As shown, an embodiment of the present invention provides an intelligent weeding device with coordinated action of a machine and pesticide, which is arranged on a traveling mechanism m and includes a frame 1 and a weeding mechanism 2.

[0017] Among them, the frame 1 is arranged on the traveling mechanism m, and a camera 11 and a transverse slide rail 12 are arranged on the frame 1. The camera 11 is used to communicate with the host computer, and the transverse slide rail 12 is arranged horizontally and perpendicular to the traveling direction of the traveling mechanism m.

[0018] The weeding mechanism 2 includes a row support 21 and a weeding unit 22. The row support 21 is slidably connected to the transverse slide rail 12, and a lifting mechanism 23 is provided on the row support 21, and the weeding unit 22 is connected to the lifting mechanism 23. The weeding unit 22 includes a weeding shovel 221, a first nozzle 222 and a second nozzle 223. The weeding shovel 221 is arranged at the bottom of the weeding unit 22. In the traveling direction of the traveling mechanism m, the first nozzle 222 is arranged behind the shovel handle 2211 of the weeding shovel 221, and the second nozzle 223 is arranged on the side of the shovel handle 2211 of the weeding shovel 221.

[0019] In an embodiment of the present invention, the intelligent weeding device with the synergistic effect of the machine and the pesticide is integrally mounted on a traveling mechanism m that can move at the planting position, using an agricultural vehicle, a tractor, etc. When weeding is required, it can be moved under the drive of the traveling mechanism m to travel between the crops a planted in rows. Before the intelligent weeding device contacts the crops a planted in rows, it first detects the row spacing of the crops a using a camera 11, lifts the weeding unit 22 to a lifted state using a lifting mechanism 23, and adjusts the relative position of the row bracket 21 on the transverse slide rail 12 according to the row spacing of the crops a, so that the weeding shovel 221 is located between the rows of the crops a. The purpose of lifting the weeding unit 22 is to space the weeding shovel 221 sufficiently from the ground to prevent the weeding shovel 221 from accidentally damaging the crops a that may exist on the travel route during the travel process. When the intelligent weeding device moves forward, the camera 11 will collect the seedling belt information of crop a in real time, detect the center line between the rows of crop a, and calculate the deviation between the center line of the row of crop a and the center of the row bracket 21 through the host computer. When the deviation is too large, the position of the row bracket 21 will be adjusted to keep the weeding shovel 221 between the rows of crop a during the movement. After completing the path alignment, the camera 11 will continue to be used to detect whether there are discrete crops a1 that are offset within the rows of crop a during the movement, that is, individual crops that grow between the rows of crop a due to deviation during the sowing process. Reference Fig. 9, if there is a discrete crop a1, in order to avoid accidental injury, after the camera 11 detects the discrete crop, the upper machine will detect the current state of the weeding unit 22, and further control the weeding unit 22 to maintain or switch to the lifted state, to ensure that the weeding shovel 221 avoids the discrete crop a1. Then, the camera 11 is used to monitor the weeds growing around the discrete crop a1 in real time. When it moves above the corresponding weed b, the first nozzle 222 is used to spray the weeds b located between the rows of crop a and distributed around the discrete crop a1 for 0.5S of liquid medicine, and the discrete weeds b caused by the discrete crop a1 are removed at a fixed point. At the same time, the side of the weeding shovel 221, that is, the second nozzle 223 located above the row of crop a planted in rows at this time, is used to spray the weeds b in the row of crop a and distributed between the plants of crop a for 0.5S of liquid medicine, and the apex of the weeds b between the plants is removed; refer to Figure 8 If the camera 11 detects that there is no discrete crop a1 between the rows, there is no need to avoid the discrete crop a1. At this time, the upper computer will detect the current state of the weeding unit 22 again, and further control the weeding unit 22 to maintain or switch to the descending state, so that the weeding unit 221 descends to a position close to the ground, and the weeding shovel 221 can be used to physically remove the weeds b between the rows of crop a during the process of traveling, and at the same time, the second nozzle 223 is used to spray the weeds b distributed in the row of crop a and between the plants of crop a for 0.5S, so as to remove the top of the weeds b between the plants.

[0020] The intelligent weeding device with the synergistic effect of the machine and the pesticide provided in the embodiment of the present invention can use the camera 11 connected to the host computer to monitor the row spacing and seedling belt information of the crop a planted in rows in real time, so as to control the row bracket 21 of the weeding mechanism 2 to adjust its position on the frame 1, so that the weeding unit 22 moves to the accurate working position. During the weeding process, the discrete crop a1 and the corresponding weed information between the rows of crop a are also monitored in real time by the camera 11 to control the switching of the working state of the weeding unit 22, so that the weeding shovel 221 is lifted up to avoid when there are discrete crops a1 and the first nozzle 222 is used to spray the liquid for weeding, and when there are no discrete crops a1, it is maintained or switched to the lowered state to achieve physical eradication. While ensuring the accurate removal of weeds between rows, the second nozzle 223 extending from the side of the weeding shovel 221 into the row of crop a is used to spray the liquid for weeding b between the plants of crop a. Through the synergistic effect of machinery and pesticides, weeds between rows and between plants of crops planted in parallel rows can be accurately removed simultaneously, solving the technical problems of low weeding accuracy and efficiency caused by insufficient flexibility and adaptability of existing weeding equipment.

[0021] For example, in the workflow of the embodiment of the present invention, the 0.5S duration of the liquid spraying by the first nozzle 222 and the second nozzle 223 is determined by the weed width, the forward speed of the device, and the detection duration. This spraying duration ensures that continuous weeds b between plants can be removed (uninterrupted spraying), and discontinuous single weeds b can be removed efficiently and accurately (fixed-point spraying). It can also be adaptively changed according to the actual weed situation, and the embodiment of the present invention does not limit the specific spraying duration.

[0022] Optionally, the weeding mechanism 2 includes two weeding units 22, which are horizontally spaced apart on the lifting mechanism 23 along the extension direction of the transverse slide rail 12, and the spacing between the two weeding units 22 is adjustable, and the two second nozzles 223 in the two weeding units 22 are respectively arranged on opposite sides of the two shovel handles 2211. Exemplarily, in the embodiment of the present invention, each row bracket 21 is equipped with two weeding units 22 which are horizontally spaced apart and have adjustable spacing. Specifically, the row support 21 includes a first driving device 211 and a longitudinal sliding arm 212, the longitudinal sliding arm 212 is arranged vertically, and is slidably connected to the transverse slide rail 12 through the first driving device 211, the lifting mechanism 23 includes a second driving device 231 and a terminal pipe frame 232, a horizontal slide rail 233 is horizontally arranged on the terminal pipe frame 232, and is slidably connected to the longitudinal sliding arm 212 through the second driving device 231, and a third driving device 224 is arranged on the two weeding units 22, and is slidably connected to the horizontal slide rail 233 through the third driving device 224. The first driving device 211, the second driving device 231 and the third driving device 224 are all motors, and the ends of their respective output shafts are installed with transmission gear structures. Accordingly, the transverse slide rail 12, the longitudinal sliding arm 212 and the horizontal slide rail 233 are all provided with rack structures that match and mesh with the transmission gear structures. For example, the terminal pipe frame 232 includes a sleeve 2321 and a square pipe frame 2322. The sleeve 2321 is sleeved on the longitudinal sliding arm 212. The second driving device 231 is connected to the outside of the sleeve 2321. Its output shaft extends into the connecting sleeve 2321, and is engaged with the rack 2121 provided on the longitudinal sliding arm 212 through the transmission gear 2311 provided at the end of the output shaft. The square pipe frame 2322 is connected to the sleeve 2321. The internal transmission adjustment of the weeding mechanism 2 is performed through the gear rack, which improves the accuracy of movement and reduces the load on the mechanism when it moves, compared with the traditional row mechanism that drives the weeding components through the hydraulic cylinder.

[0023] After receiving the control signal from the host computer, the first driving device 211 drives the entire row support 21 and the parts connected thereto to move horizontally along the transverse slide rail 12; the second driving device 231 drives the end pipe frame 232 to rise and fall on the longitudinal sliding arm 212 to drive the two weeding units 22 to rise and fall synchronously; and the third driving device 224 drives the two weeding units 22 to move horizontally on the horizontal slide rail 233 to adjust the spacing by moving them closer or farther from each other. By configuring two weeding units 22 with adjustable horizontal spacing in the weeding mechanism 2, the spacing can be flexibly adjusted according to the actual row spacing of the crop a to ensure the coverage of the weeding between the rows. In combination with the two second nozzles 223 in the two weeding units 22 being respectively arranged on the opposite sides of the two shovel handles 2211, it is possible to use one weeding mechanism 2 to simultaneously weed the two rows of crops a on both sides during the process of traveling, thereby maximizing the weeding coverage area and improving the weeding efficiency.

[0024] Optionally, the weeding unit 22 further includes a vertically arranged longitudinal connecting arm 225, the top of the longitudinal connecting arm 225 is connected to the third driving device 224, and the weeding shovel 221 is arranged at the bottom of the longitudinal connecting arm 225. In the traveling direction of the traveling mechanism m, the weeding shovel 221 of one of the two weeding units 22 is arranged at the front side of the corresponding longitudinal connecting arm 225, and the weeding shovel 221 of the other one is arranged at the rear side of the corresponding longitudinal connecting arm 225. Exemplarily, in the embodiment of the present invention, the longitudinal connecting arm 225 serves as a supporting component connecting the third driving device 224 and the weeding shovel 221, the first nozzle 222, and the second nozzle 223. When adjusting the spacing between the two weeding units 22, the weeding shovels 221 are staggeredly installed on the two longitudinal connecting arms 225 one after the other through the horizontal square tube, so that the two weeding units 22 can avoid collision and interference of the weeding shovels 221 when the spacing is small, thereby increasing the spacing adjustment range and increasing adaptability.

[0025] Optionally, the square tube frame 2322 includes a transverse square tube 23221 and longitudinal square tubes 23222 arranged at both ends of the transverse square tube 23221, the horizontal slide rail 233 is connected between the two longitudinal square tubes 23222, and a first guide support rod 23223 arranged parallel to the horizontal slide rail 233 and spaced between the two longitudinal square tubes 23222 is also arranged between the two longitudinal square tubes 23222, and the first guide support rod 23223 is penetrated through the longitudinal connecting arm 225. Exemplarily, in the embodiment of the present invention, the transverse square tube 23221 serves as the connecting part between the square tube frame 2322 and the sleeve 2321, and a setting space for the horizontal slide rail 233 and a horizontal movement space for the two longitudinal connecting arms 225 are formed between the two longitudinal square tubes 23222. On this basis, by additionally providing a plurality of first guide support rods 23223 penetrating the longitudinal connecting arm 225 between the two longitudinal square tubes 23222, it is possible to achieve additional support for the longitudinal connecting arm 225, as well as limit guidance during horizontal position adjustment, thereby improving overall working stability.

[0026] Optionally, the connection between the first drive device 211 and the longitudinal sliding arm 212, the connection between the second drive device 231 and the sleeve 2321, and the connection between the third drive device 224 and the longitudinal connecting arm 225 are all provided with an angle code 3. Exemplarily, in the embodiment of the present invention, by providing an angle code 3 at the turning position of the connection between the first drive device 211 and the longitudinal sliding arm 212, the connection between the second drive device 231 and the sleeve 2321, and the connection between the third drive device 224 and the longitudinal connecting arm 225, the mechanical strength at the connection position is improved, loosening or deformation damage due to vibration during operation is avoided, and the overall mechanical stability is improved.

[0027] Optionally, the frame 1 is further provided with a second guide support rod 13 arranged in parallel and spaced relation with the transverse slide rail 12, and the second guide support rod 13 is passed through the longitudinal slide arm 212. For example, in the embodiment of the present invention, by additionally providing a plurality of second guide support rods 13 passing through the longitudinal slide arm 212 above and below the transverse slide rail 12, it is possible to achieve additional support for the longitudinal slide arm 212 and limit guide during horizontal position adjustment, thereby further improving the overall working stability.

[0028] Optionally, a plurality of weeding mechanisms 2 are provided, and are arranged horizontally at intervals along the extension direction of the transverse slide rail 12. For example, in the embodiment of the present invention, the width of the frame 1 and the transverse slide rail 12 can be set as large as possible according to the specifications of the traveling mechanism m, and multiple groups of weeding structures 2 are connected to the transverse slide rail 12. According to the actual planting row spacing of the crop a, the horizontal positions of the multiple groups of weeding mechanisms 2 can be adjusted along the transverse slide rail 12 to achieve simultaneous removal of weeds b between rows and plants of multiple rows of crops a, further improving work adaptability and weeding efficiency.

Fig.10 As shown, the embodiment of the present invention also provides a weeding method based on Figures 1 to 9 The ballast track maintenance test device shown is implemented, including: S1, using the traveling mechanism m to drive the intelligent weeding device with the synergistic effect of the weeding machine and the pesticide to move between the crops a planted in rows.

[0031] S3, using the camera 11 to detect whether there is a discrete crop a1 that is offset within the row between the crop a rows, If there is a discrete crop a1, the weeding unit 22 is controlled to remain in or switch to the raised state, and the first nozzle 222 is used to spray the weeds b located between the rows of crop a and distributed around the discrete crop a1, and the second nozzle 223 is used to spray the weeds b in the row of crop a and distributed between the plants of crop a; If there is no discrete crop a1, the weeding unit 22 is controlled to maintain or switch to the descending state, and the weeding shovel 221 is used to physically remove the weeds b between the rows of crop a; the second nozzle 223 is used to spray the weeds b distributed in the row of crop a and between the plants of crop a with liquid medicine.

[0032] The intelligent weeding device with the synergistic effect of the machine and the pesticide provided in the embodiment of the present invention is adopted, and the above-mentioned weeding method is used to weed between the rows and between the plants of the crops a planted in parallel in multiple rows. The row spacing and seedling belt information of the crops a planted in rows can be monitored in real time by using the camera 11 connected to the host computer, so as to control the position adjustment of the row support 21 of the weeding mechanism 2 on the frame 1, so that the weeding unit 22 moves to the accurate working position. During the weeding process, the discrete crops a1 and the corresponding weed information between the rows of the crops a are also monitored in real time by the camera 11, so as to control the switching of the working state of the weeding unit 22, so that the weeding shovel 221 is lifted up to avoid when the discrete crops a1 exist, and the first nozzle 222 is used to spray the liquid for weeding, and when the discrete crops a1 do not exist, it is maintained or switched to the lowered state to achieve physical eradication.
