Description

Technical Field

[0001] The present invention relates to the technical field of agricultural weeding, and in particular to an intelligent weeding device based on the Internet of Things. Background Art

[0002] In the process of planting crops, weeds will grow in the farmland and rob the crops of their nutrients, so they need to be removed, and weeding equipment is used. With the development of science and technology and the application of the Internet of Things, crop weeding has become more intelligent. Intelligent weeding equipment based on the Internet of Things can use various sensors to perceive information in the farmland environment, and transmit these data to the cloud platform or local server for analysis and processing through network communication. Then, the operation of the weeding equipment is automatically controlled according to the analysis results, so as to achieve accurate, efficient and environmentally friendly weeding operations. By turning the soil around the crops, the weeds can be uprooted or their roots can be destroyed, effectively preventing the regeneration of weeds, thereby achieving a more lasting weeding effect and reducing the long-term competition of weeds on crop growth.

[0003] However, the existing agricultural weeding equipment still has the following problems during use: when clearing weeds, the active gap and active amplitude of the turning parts are relatively fixed. When weeding crops with different planting needs, it is inconvenient to adaptively adjust the equipment according to the size and spacing of the crops. This causes the equipment to deviate from the preset weeding area during the weeding process, resulting in omission of the weeding area or misoperation of the non-weeding area, reducing the intelligence level of the equipment. At the same time, it is inconvenient to adjust the amplitude and mode of the soil turning action, which may cause excessive turning or compaction of the soil. For example, in an area with small spacing between crops, if the soil turning range is not properly controlled, the soil structure of the entire planting area will be destroyed.

[0004] Therefore, we proposed an intelligent weeding device based on the Internet of Things to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent weeding device based on the Internet of Things to solve the problem that the existing intelligent weeding device based on the Internet of Things on the market is inconvenient to adjust the equipment adaptively according to the size and spacing of crops during use, and to adjust the spacing of the turning parts and the amplitude and method of the soil turning action.

[0019] Compared with the prior art, the beneficial effect of the intelligent weeding equipment based on the Internet of Things of the present invention is that when in use, the spacing of the turning parts on the weeding equipment and the amplitude and mode of the soil turning action can be adaptively adjusted according to the distribution size and distribution gap of the crops, so as to achieve a better weeding effect. The specific contents are as follows:

[0020] 1. By setting the spacing adjustment component, when weeding crops with different planting spacings, the positions of the turning rod and the shovel blade are adaptively adjusted, the turning rod is kept on the outer sides of the crops to turn the soil, the shovel blade is in the gap between adjacent crops, the variable pitch screw drives the second mounting frame to slide in the transverse groove, and then adjusts the distance between adjacent turning rod groups, and at the same time, the first piston rod slides in the first oil tank, the oil in the first oil tank is squeezed out and injected into the second oil tank through the connecting pipe, and then the second piston rod is pushed out, the first spring is stretched, and the second piston rod is extended to push the first mounting frame to move in the slide groove, so that the first mounting frame and the shovel blade are always kept on the center line between the adjacent second mounting frames, so as to maintain the turning and removal effect of weeds;

[0021] 2. By setting an angle adjustment component, the use angle of the shovel blade can be adjusted synchronously while adjusting the spacing. During the movement of the first mounting frame, the second gear meshes with the rack to drive the shaft rod to rotate. The shaft rod drives the shaft rods of the same group to rotate relatively through the first gear. After the shaft rod rotates, the bottom shovel blade is driven to rotate synchronously, thereby adjusting the deployment angle of the shovel blade. The scraping range of the shovel blade is synchronously adjusted according to the change in the spacing of the crops to avoid damaging the crops.

[0022] 3. By setting the amplitude adjustment component, the amplitude of the flipping needs to be adjusted synchronously when the spacing changes, so as to avoid damaging crops due to a large flipping amplitude. The second electric push rod pushes a constant distance each time, and the sliding of the sliding rod in the oil cylinder will change the moving distance of the tooth plate. The moving distance of the tooth plate will affect the rotation angle of the third gear. The third gear drives the flipping rod to open and close synchronously through the driving rod, thereby adjusting the flipping range of the flipping rod to adapt to crops with different gaps;

[0023] Furthermore, when the turning rod opens and closes, it will intermittently squeeze and contact with the protrusion, causing the turning rod to slide vertically on the driving rod, thereby squeezing the second spring. The turning rod opens and closes and slides vertically, thereby enhancing the turning of the soil and the breaking of soil clods. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1 - Fig.11As shown, the present invention provides a technical solution: an intelligent weeding device based on the Internet of Things, comprising a body 1, and a visual sensor 2 and a position sensor 3 are distributed and installed on the front and rear sides of the middle of the top surface of the body 1, and a laser radar sensor 4 is arranged at the bottom of the body 1, a processor and a control unit are carried inside the body 1, and the visual sensor 2 collects images of the field environment to identify crops and weeds, and the position sensor 3 is used to determine the specific position and movement trajectory of the weeding device in the field, and the laser radar sensor 4 uses a laser beam to scan the surrounding environment to obtain high-precision three-dimensional space information. In order to improve the weeding efficiency, a first electric push rod 5 is installed in the middle of the bottom surface of the machine body 1, and a truss 6 is fixed at the bottom of the first electric push rod 5, and a first mounting frame 7 is evenly spaced on the front side of the bottom of the truss 6, and a small roller 8 is installed on the front side of the bottom of the first mounting frame 7, and a fixed frame 9 is installed on the rear side of the bottom of the first mounting frame 7, and an inclined blade 10 is symmetrically arranged at the bottom of the fixed frame 9, and a second mounting frame 11 is evenly spaced on the rear side of the bottom of the truss 6, and a flip rod 12 is symmetrically rotatably connected to the bottom of the second mounting frame 11, and the blade 10 is located on the midline position of the adjacent second mounting frame 11;

[0038] First, the basic weeding operation of the equipment is introduced. The machine body 1 is placed in the farmland and walks step by step. The visual sensor 2 is used to collect images of the field environment to identify crops and weeds, and then accurately find the location of the weeds. The position sensor 3 is used to determine the specific position and movement trajectory of the weeding equipment in the field. The laser radar sensor 4 uses a laser beam to scan the surrounding environment, which can obtain high-precision three-dimensional spatial information and improve the weeding efficiency. The first electric push rod 5 drives the truss 6 to move downward, so that the small roller 8 contacts the field. The blade 10 of the fixing frame 9 at the bottom of the first mounting frame 7 walks in the gap between adjacent crops. The turning rod 12 under the second mounting frame 11 turns the soil close to the root system of the crop by opening and closing. Turning the soil can uproot the weeds or destroy their roots, effectively preventing the regeneration of weeds, thereby achieving a more lasting weeding effect.

[0039] Embodiment 1: When weeding crops with different planting spacings, the corresponding components are adaptively adjusted in spacing, so the following solution is proposed. Please refer to Figure 3 - Figure 5 and Fig. 9 As shown;

[0040] When adjusting the position of the flip rod 12, Figure 5 As shown;

[0041] A spacing adjustment component 13, the spacing adjustment component 13 is arranged inside the truss 6, and the spacing adjustment component 13 adjusts the positions of the shovel blade 10 and the flip rod 12 according to the size of the planting gap of the crops, the spacing adjustment component 13 includes a variable pitch screw 131, and the variable pitch screw 131 passes through the bearing and is connected to the inside of the transverse groove 132, and the transverse groove 132 is opened at the bottom rear side of the truss 6, and the variable pitch screw 131 is driven by a motor installed in the truss 6, and at the same time, the variable pitch screw 131 is threadedly connected to the second mounting frame 11, and the outer side of the second mounting frame 11 is fixed with a first piston rod 133, and the end of the first piston rod 133 is sealed and slidably connected to the first oil tank 134, and the first oil tank 134 is arranged between adjacent second mounting frames 11;

[0042] When in use, the motor inside the truss 6 drives the variable pitch screw 131 to rotate, so that the second mounting frames 11 on both sides are moved closer to the middle of the transverse groove 132 while maintaining the same spacing, thereby adjusting the distance between adjacent groups of flipping rods 12 to adapt to crops planted at different spacings. After the second mounting frames 11 move, they drive the first piston rod 133 to slide in the first oil tank 134, thereby squeezing out the oil.

[0043] When the position of the blade 10 is adjusted synchronously, Fig. 9 As shown;

[0044] The first oil tank 134 is connected to the second oil tank 136 through a connecting pipe, and the second oil tank 136 is installed inside the slide groove 135, and the slide groove 135 is evenly spaced and opened at the bottom front side of the truss 6, and the second oil tank 136 is sealed and slidably connected with a second piston rod 137 through a first spring 138, and the outer end of the second piston rod 137 is fixedly connected to the top of the first mounting frame 7;

[0045] At the same time, the oil in the first oil tank 134 is squeezed out and injected into the second oil tank 136 through the connecting pipe, thereby pushing the second piston rod 137 to extend, and the first spring 138 is stretched. After the second piston rod 137 extends, it pushes the first mounting frame 7 to move in the slide groove 135, so that the first mounting frame 7 and the shovel blade 10 are always kept on the center line between the adjacent second mounting frames 11, thereby maintaining the turning and removing effect of the weeds;

[0046] Embodiment 2: After the spacing is adjusted, the angles of the related components are adjusted synchronously. Therefore, the following solution is proposed. Please refer to Figure 2 - Figure 4 and Fig.10 - Fig.11 As shown;

[0047] The angle adjustment component 14 is arranged inside the first mounting frame 7 and the fixed frame 9, and the angle adjustment component 14 adjusts the deployment range of the blade 10 according to the planting gap size of the crops. The angle adjustment component 14 includes shafts 141 that are evenly spaced and grouped at the bottom of the first mounting frame 7, and the bottom of the shaft 141 is fixed to the top of the blade 10, and the top of the shaft 141 passes through the fixed frame 9 and is connected to the inside of the first mounting frame 7, and the top of the shaft 141 is the first gear 142. At the same time, the first gears 142 on a group of shafts 141 are meshed and connected with each other, and a second gear 143 is fixed to one of the shafts 141 on the group of shafts 141, and the rear side of the second gear 143 is meshed and connected with a rack 144, and the rack 144 passes through the left and right sides of the first mounting frame 7 and is installed at the bottom of the truss 6, and the rack 144 is set to a "U"-shaped structure. At the same time, the blade 10 forms an angle adjustment structure through the shaft 141, the first gear 142, the second gear 143 and the rack 144;

[0048] When in use, during the movement of the first mounting frame 7, the second gear 143 will mesh with the rack 144, thereby driving the shaft rod 141 to rotate. After the shaft rod 141 rotates, the first gear 142 meshes with the shaft rod 141 in the same group to relatively rotate. After the shaft rod 141 rotates, the blade 10 at the bottom is driven to rotate synchronously, thereby adjusting the deployment angle of the blade 10, and synchronously adjusting the scraping range of the blade 10 according to the change in the spacing of the crops to avoid damaging the crops.

[0049] Example 3: When weeding crops with different planting spacing, the amplitude of the corresponding soil turning action is adjusted to maintain a good weeding effect without damaging the crops. Therefore, the following solution is proposed. Please refer to Figure 4 and Figure 6 - Figure 8 As shown;

[0050] Amplitude adjustment component 15, the amplitude adjustment component 15 is arranged inside and at the bottom of the second mounting frame 11, and the amplitude adjustment component 15 adjusts the flipping range and amplitude of the flipping rod 12 according to the planting gap size of the crops, the amplitude adjustment component 15 includes a second electric push rod 151 installed inside the second mounting frame 11, and an oil cylinder 152 is fixed to the end of the second electric push rod 151, and a sliding rod 153 is sealed and slidably connected to the end of the oil cylinder 152, and the oil cylinder 152 is connected to the first oil tank 134 through a connecting pipe, and a tooth plate 154 is fixed to the end of the sliding rod 153, and the tooth plate 154 is set to a "U"-shaped structure, and a third gear 155 is symmetrically arranged on the inner side of the second mounting frame 11, and the tooth plate 154 is meshed and connected with the third gear 155 after moving, and a driving rod 156 is fixed to the bottom of the third gear 155, and the driving rod 156 passes through the bearing and is connected to the bottom of the second mounting frame 11;

[0051] When the flipping amplitude is changed, during the gap adjustment process of the second mounting frame 11, the oil in the first oil tank 134 is squeezed out and then synchronously injected into the oil barrel 152 through the connecting pipe, the sliding rod 153 in the oil barrel 152 slides, and the second electric push rod 151 pushes a constant distance each time, and the moving distance of the tooth plate 154 is changed by changing the extension length of the sliding rod 153. The moving distance of the tooth plate 154 affects the rotation angle of the third gear 155. After the tooth plate 154 moves, it meshes with the third gear 155. After the third gear 155 rotates, it drives the driving rod 156 at the bottom to rotate synchronously, and the driving rod 156 drives the flipping rod 12 to open and close synchronously, thereby adjusting the flipping range of the flipping rod 12 to adapt to crops with different gaps;

[0052] The upper half of the driving rod 156 is set as a cylindrical structure, and the lower half of the driving rod 156 is set as a rectangular structure, and the outer side of the lower part of the driving rod 156 is slidably connected with the flip rod 12, and a second spring 157 is installed between the bottom of the top surface of the flip rod 12 and the bottom of the driving rod 156, and the bottom of the second mounting frame 11 is symmetrically provided with hemispherical protrusions 158 at equal angles, and the flip rod 12 forms a vertical sliding structure through the second spring 157 and the protrusion 158;

[0053] When in use, when the turning rod 12 opens and closes, its top will intermittently squeeze and contact with the protrusion 158 at the bottom of the second mounting frame 11, so that the turning rod 12 slides vertically on the driving rod 156, thereby squeezing the second spring 157. The turning rod 12 opens and closes and slides vertically at the same time, thereby enhancing the turning of the soil and the breaking of soil clods, and preventing large soil clods from rolling onto crops during turning.
