Description

Technical Field

[0001] The present invention relates to the technical field of weeding instruments, and particularly relates to a floating mowing structure and a weeding robot. Background Art

[0002] A photovoltaic power station is a photovoltaic power generation system that utilizes solar energy and consists of a power generation system composed of special materials (such as crystalline silicon panels) and electronic devices (such as inverters), which is connected to the power grid and transmits electricity to the power grid. With continuous development, the scale of photovoltaic power stations has gradually expanded, and the application scenarios have become more diverse. The overall operation and maintenance of photovoltaic power stations have become particularly important. For example, in some areas where weeds and shrubs grow vigorously, if the weeds and shrubs grow too tall, they will block the photovoltaic panels, greatly reducing the efficiency of photovoltaic power generation. At the same time, excessive weeds and shrubs also pose a risk of fire and potential safety hazards.

[0003] Thus, it can be seen that the weeding work of photovoltaic power stations is particularly important. Currently, the weeding work of photovoltaic power stations is mostly carried out by weeding robots. A weeding robot generally includes a vehicle body and a mowing structure. The vehicle body is equipped with crawlers or mobile wheels, which can drive the entire device to move. The mowing structure is connected to the vehicle body and is equipped with a mowing head on it. The cutter head on the mowing head rotates to achieve mowing and weeding. However, the ground of photovoltaic power stations is sometimes uneven, and there may also be hard obstacles such as stones. When the mowing structure is working, the mowing head is very easy to touch the ground or obstacles and get damaged. Summary of the Invention

[0017] In an alternative embodiment, the link mechanism includes: two telescopic rods and two linkage rods. The two telescopic rods are respectively arranged on both sides of the connecting frame, with their fixed ends connected to the connecting frame and their driving ends connected to the mounting plate. The two linkage rods are also respectively arranged on both sides of the connecting frame, with one end connected to the connecting frame and the other end connected to the mounting plate.

[0018] Beneficial effects

[0019] This link mechanism enables the floating mowing structure to be lifted or lowered, presenting different postures, so as to adapt to different types of working conditions.

[0020] In an alternative embodiment, the floating mowing structure further includes a mounting plate shock-absorbing component. One side of the mounting plate shock-absorbing component is connected to the mounting plate, and the other side is connected to the linkage rod.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the protection scope of the present invention.

[0049] The following will describe the embodiments of the present invention in conjunction with Figures 1 to 9 , to describe the embodiments of the present invention.

[0050] According to an embodiment of the present invention, on the one hand, a floating mowing structure is provided, which includes: a connecting frame 1, a mounting plate 2, a linkage mechanism 3, and a mowing mechanism 4. The mounting plate 2 is connected to the connecting frame 1 through the linkage mechanism 3. The mowing mechanism 4 includes a plurality of mowing heads arranged at intervals on the mounting plate 2. The mowing head includes: a driving member 41, a mowing head shock-absorbing assembly 42, a connecting assembly 43, and a cutter head 44. The mowing head shock-absorbing assembly 42 is arranged between the driving member 41 and the mounting plate 2. One end of the connecting assembly 43 is connected to the driving end of the driving member 41, and the other end passes through the mounting plate 2 and is provided with the cutter head 44.

[0051] As Figures 1 to 3 shown, the connecting frame 1 is a structure for the transitional connection between the floating mowing structure and the vehicle body of the weeding robot. Specifically, the connecting plate includes: a main board 11 and two side boards 12 arranged on both sides of the main board 11. The side boards 12 are perpendicular to the main board 11, forming a semi-enclosed structure. The mounting plate 2 bears the mowing mechanism 4 and provides an installation environment for the setting of the mowing mechanism 4. Specifically, the mounting plate 2 includes: a panel 21 and two skirt boards 22. The two skirt boards 22 are arranged at both ends of the panel 21 and extend vertically downward. The mowing space of the mowing mechanism 4 is between the two skirt boards 22. Generally, the position of the connecting frame 1 is higher, the position of the mounting plate 2 is lower, and the connecting frame 1 and the mounting plate 2 are connected into a whole through the linkage mechanism 3. The plurality of mowing heads of the mowing mechanism 4 are arranged at intervals along the length direction of the mounting plate 2, and the mowing range of the mowing head should ensure that it can cover the entire mowing space. Each group of mowing heads includes: a driving member 41, a mowing head shock-absorbing assembly 42, a connecting assembly 43, and a cutter head 44. The rotational power provided by the driving member 41 is transmitted to the cutter head 44 through the connecting assembly 43, and the cutter head 44 rotates to achieve mowing. A mowing head shock-absorbing assembly 42 is arranged between the driving member 41 and the mounting plate 2. The mowing head shock-absorbing assembly 42 can not only realize the fixed installation of the driving member 41 but also provide vertical shock absorption and floating avoidance for the mowing head. When the mowing head touches the ground or a hard obstacle during mowing, vertical floating avoidance can be realized to prevent the mowing head from being directly damaged.

[0052] In some embodiments, the linkage mechanism 3 includes: two telescopic rods 31 and two linkage rods 32. The two telescopic rods 31 are respectively arranged on both sides of the connection frame 1, with their fixed ends connected to the connection frame 1 and their driving ends connected to the mounting plate 2. The two linkage rods 32 are also respectively arranged on both sides of the connection frame 1, with one end thereof connected to the connection frame 1 and the other end connected to the mounting plate 2.

[0053] As Figures 1 to 3 shown, the two telescopic rods 31 are respectively arranged on both sides of the connection frame 1, that is, the mounting ends of the two telescopic rods 31 are respectively hinged to the two side plates 12, and the driving ends of the two telescopic rods 31 are respectively hinged to the top surface of the panel 21. The two linkage rods 32 are also respectively arranged on both sides of the connection frame 1. One ends of the two linkage rods 32 are respectively hinged to the two side plates 12, but the connection positions are below the connection positions between the mounting ends of the telescopic rods 31 and the side plates 12, and the other ends of the two linkage rods 32 are hinged to the bottom surface of the panel 21. The telescopic rod 31 is preferably an electric push rod, and the telescoping of the electric push rod can drive the entire mounting plate 2 to flip. As Figures 4 to 6 shown, when the electric push rod extends, it drives the mounting plate 2 to lower, and generally, mowing work is to be carried out at this time; when the electric push rod retracts, it drives the mounting plate 2 to flip upward, and generally, it is not in the mowing work at this time, and it mostly adapts to the fast-traveling state of the weeding robot.

[0054] In some embodiments, the telescopic rod 31 is connected to the connection frame 1 through a telescopic rod shock-absorbing assembly 6. That is, the mounting end of the telescopic rod 31 is not directly hinged to the side plate 12 of the link frame, but is connected through the telescopic rod shock-absorbing assembly 6. The setting of the telescopic rod shock-absorbing assembly 6 can provide floating and shock buffering for the telescopic rod 31, and improve the overall adaptability of the floating mowing structure.

[0055] In one embodiment, the telescopic rod shock-absorbing assembly 6 includes: a base 61, a connection seat 62, a third elastic member 63 and a guide member 64. The base 61 is connected to the connection frame 1, the connection seat 62 is connected to the mounting end of the telescopic rod 31, the third elastic member 63 is arranged between the base 61 and the connection seat 62 and sleeved on the guide member 64. One end of the guide member 64 is fixedly arranged on the base 61, and the other end is slidably connected to the connection seat 62.

[0056] Specifically, as Figure 9 shown, the base 61 is an L-shaped plate and is fixedly connected to the side plate 12 of the connection frame 1 by bolts. A hinge seat is arranged on the side of the connection seat 62 away from the base 61 for hinging the mounting end of the telescopic rod 31. The third elastic member 63 is preferably a spring arranged between the base 61 and the connection seat 62, and both ends of the third elastic member 63 are respectively abutted against the base 61 and the connection seat 62. To guide the movement direction of the third elastic member 63, a guide member 64 is also arranged. One end of the guide member 64 is fixedly connected to the base 61, and the other end sequentially passes through the third elastic member 63 and the connection seat 62.

[0057] In addition, four guide rods 65 parallel to the guide member 64 are provided at the four corners of the connection base 62 and the base 61. The guide rods 65 are also fixedly connected to the base 61 and slidably connected to the connection base 62. When the connection base 62 is acted upon by an external force, it can slide along the axial direction of the guide member 64, and the external force is buffered by the deformation of the third elastic member 63.

[0058] In daily work, the shock absorption module of the telescopic rod 31 has a certain shock absorption capacity to buffer the telescopic rod 31. When the floating mowing structure as a whole encounters a large impact such as a slope, the shock absorption module of the telescopic rod 31 can float and avoid, enabling the entire mounting plate 2 to have a corresponding angle adjustment to prevent overall damage.

[0059] In some embodiments, the floating mowing structure further includes a mounting plate shock absorption assembly 5. One side of the mounting plate shock absorption assembly 5 is connected to the mounting plate 2, and the other side is connected to the linkage rod 32. The setting of the mounting plate shock absorption assembly 5 can provide effective floating and shock absorption buffering for the mounting plate 2, improving the overall adaptability of the floating mowing structure.

[0060] In one embodiment, the mounting plate shock absorption assembly 5 includes: a second elastic member 51 and two connecting plates 52. The two connecting plates 52 are arranged oppositely, and one of the connecting plates is connected to the mounting plate 2, and the other connecting plate is connected to the linkage rod 32. The second elastic member 51 is arranged on the two connecting plates 52.

[0061] As Figure 5 shown, the two connecting plates 52 are spaced apart vertically and oppositely. The upper connecting plate is connected to the bottom surface of the panel 21 of the mounting plate 2, and the connection method is by bolt fixation. The lower connecting plate is connected to the top surface of the linkage rod 32, and the connection method is also by bolt fixation. The second elastic member 51 is connected to the two connecting plates 52. The second elastic member 51 is preferably a steel wire rope. This mounting plate shock absorption assembly 5 can provide floating and shock absorption buffering for the mounting plate 2 in the length direction and the height direction. When the mowing head encounters some obstacles, the mounting plate 2 can make appropriate avoidance. At the same time, the combined application of the mounting plate shock absorption assembly 5 and the telescopic rod shock absorption assembly 6 can also effectively reduce the vibration received by the mowing head during the mowing operation, making the operation more stable.

[0062] In some embodiments, the mowing head shock-absorbing assembly 42 includes: an end sleeve 421, a guide body 422, a first elastic member 423, and a fastener 424. A plurality of first mounting holes are formed in the connecting flange of the driving member 41, and a plurality of second mounting holes are formed in the mounting plate 2. The positions of the first mounting holes and the second mounting holes correspond one by one. An end sleeve 421 is arranged in the first mounting hole. Both ends of the guide body 422 are respectively located in the end sleeve 421 and the second mounting hole, and fasteners 424 are arranged at both ends of the guide body 422. The portion of the guide body 422 located between the connecting flange and the mounting plate 2 is sleeved with the first elastic member 423, and both ends of the first elastic member 423 are respectively abutted against the connecting flange and the mounting plate 2.

[0063] As Figure 7 , Figure 8 shown, the driving member 41 is preferably a motor, and the output shaft of the motor, that is, the driving end, faces the top surface of the mounting plate 2. The motor has a connecting flange, and a plurality of first mounting holes are formed in advance on the connecting flange. In this embodiment, four first mounting holes are formed on each connecting flange, corresponding to the four corners of the motor. Correspondingly, second mounting holes are provided on the mounting plate 2 at positions corresponding to each first mounting hole. Threaded holes are formed at both ends of the guide body 422. The lower end of the guide hole is connected to the mounting plate 2 and fixed by a fastener 424 arranged in the threaded hole at its lower end. An end sleeve 421 is arranged in the first mounting hole. In this embodiment, the end sleeve 421 is preferably a copper sleeve. The copper sleeve is arranged in the second mounting hole and its upper end is clamped with the connecting flange. The upper end of the guide body 422 is arranged in the copper sleeve and fixed by a fastener 424 arranged in the threaded hole at its upper end. The fastener 424 includes a flat gasket and a bolt. The portion of the guide body 422 located between the bottom surface of the connecting flange and the top surface of the mounting plate 2 is sleeved with the first elastic member 423. The first elastic member 423 is preferably a rectangular spring, and both ends of the rectangular spring are respectively abutted against the bottom surface of the connecting flange and the top surface of the mounting plate 2. A through hole is formed in the mounting plate 2 for the connecting assembly 43 to pass through. The upper end of the connecting assembly 43 is connected to the driving end of the driving member 41, and the lower end extends below the mounting plate 2 and is provided with a cutter head 44 to transmit the power of the driving member 41 to the cutter head 44 to drive the cutter head 44 to rotate for mowing.

[0064] After the mowing head shock-absorbing assembly 42 is provided, the driving member 41 (motor) can float axially along the guide body 422, so that the cutter head 44 has a certain avoidance ability. When the cutter head 44 impacts the ground or a hard obstacle during the mowing operation, it can avoid hard collision with it and damage.

[0065] In some embodiments, the connecting assembly 43 includes: a connecting shaft 431 and a transfer disk 432. One end of the connecting shaft 431 is connected to the driving end of the driving member 41, and the other end is provided with a transfer disk 432, and a cutter head 44 is arranged on the transfer disk 432.

[0066] AsFigure 7 , Figure 8 As shown in Figure 8 , the connecting shaft 431 passes through the mounting plate 2, its upper end is connected to the driving end of the driving member 41, and a transfer disk 432 is provided at the lower end. The transfer disk 432 is in a disk shape and is connected to the cutter head 44. When the driving member 41 is started, it can drive the connecting shaft 431, the transfer disk 432 and the cutter head 44 to rotate synchronously.

[0067] Furthermore, multiple grass cutting blades 45 can be additionally installed on the transfer disk 432 to prevent the cut grass from winding around the cutter head 44, effectively realizing the debris function.

[0068] In some embodiments, the cutter head 44 is a six - blade cutter head 44, that is, the cutter head 44 has six blades. Of course, in other embodiments, the number of blades on the cutter head 44 can also be other numbers, and this embodiment does not make specific limitations.

[0069] In some embodiments, multiple cutter heads 44 are arranged in a staggered manner in height.

[0070] As Figure 2 shown, in this embodiment, a total of four mowing heads are provided, but the positions of the cutter heads 44 are arranged in a staggered manner, one high and one low. And the distance between two adjacent cutter heads 44 is less than the diameter of the cutter head 44, that is, viewed from the axial direction of the cutter head 44, there is an overlap between adjacent cutter heads 44. This setting method can ensure that the plants within the cutting width of the mowing structure can all be cut.

[0071] On the other hand, this embodiment also provides a weeding robot, including a floating mowing structure and a vehicle body. The floating mowing structure is the same as the floating mowing structure in the above - mentioned embodiment, so it will not be elaborated here. The vehicle body mainly provides the walking ability for the weeding robot, and it can be in various forms such as a wheeled vehicle body or a tracked vehicle body.

[0072] The working process of the weeding robot provided in this embodiment is described as follows:

[0073] The telescopic rod 31 extends to lower the mounting plate 2, and the mowing head enters the working state. The driving member 41 is started to drive the cutter head 44 to rotate to start mowing. The vehicle body moves continuously to change the mowing construction position. During the working process, when the mowing head encounters the ground or a hard obstacle, the mowing head shock - absorbing component 42 can enable the driving member 41 to float and avoid along the axial direction of the guiding body 422, preventing the cutter head 44 from directly colliding with the obstacle and being damaged. At the same time, the mounting plate shock - absorbing component 5 and the telescopic rod shock - absorbing component 6 can also provide floating avoidance in different directions, and can also provide shock absorption and buffering for the entire floating mowing structure. This floating mowing structure can achieve floating avoidance and shock absorption and buffering in different directions through the cooperation of multiple shock - absorbing components, and is suitable for various terrains.

[0074] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
