Description

Technical Field

[0001] This utility model relates to the field of weeding machinery technology, specifically to a shock absorption device for a weeding robot. Background Technology

[0002] In agricultural planting, weeds grow in the fields and need to be removed. Currently, manual chemical weeding is widely used. However, with people’s increasing concern about food safety, the spraying of chemical herbicides has been gradually replaced by mechanical weeding, which has achieved certain results. In order to improve the efficiency and save labor, weeding robots are now mainly used for weeding operations. Weeding robots will generate vibrations during operation, which need to be damped.

[0003] However, existing shock absorption devices for weeding robots are generally fixed to the wheel frame of the weeding robot by multiple bolts. This means that during installation and disassembly, each wheel needs to be repeatedly installed and removed from multiple bolts, which is time-consuming and reduces work efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a shock-absorbing device for weeding robots, which solves the problem mentioned in the background technology that each wheel requires repeated disassembly and reassembly of multiple bolts during installation and disassembly, which is time-consuming and reduces work efficiency.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: A shock-absorbing device for a weeding robot, comprising a main body and four mounting cylinders, each with a wheel mounted at its bottom end. A control seat is fixedly connected to the front end of the main body, and a control groove is formed at the front end of the control seat. A threaded rod is rotatably connected inside the control groove, and a threaded component is threaded onto the threaded rod. One end of the threaded component passes through the control groove and is connected to an extension plate, on which a weeding blade is mounted. A motor connected to the threaded rod is mounted at the top of the control seat, and connecting rods are fixedly connected to the four corners of the bottom end of the main body. Each of the four mounting cylinders has a sliding groove, and two limiting grooves are formed on the inner sidewall of the sliding groove. A limiting block is slidably connected between the two limiting grooves, and a bolt is threaded onto the limiting block. The four mounting cylinders are respectively fitted onto the four connecting columns. Each of the four connecting columns has a threaded groove that mates with the bolt. Each of the four mounting cylinders has a shock-absorbing cylinder inside, and a shock-absorbing rod is slidably connected inside the shock-absorbing cylinder. The top end of the shock-absorbing rod is in close contact with the connecting column, and a damper that mates with the shock-absorbing cylinder is provided on the shock-absorbing rod. A shock-absorbing spring is provided between the shock-absorbing rod and the shock-absorbing cylinder.

[0008] By adopting the above technical solution, the starting motor drives the threaded rod to rotate, which in turn moves the threaded parts and the extension plate. The extension plate then moves the mowing blade, allowing it to reach a suitable height for mowing. When the equipment is subjected to vibration, the connecting column slides inside the mounting cylinder, causing the shock absorber rod to slide inside the cylinder as well. This causes the shock absorber spring to contract and extend, reducing vibration and the power transmitted through it, thus achieving vibration damping. When the damping device needs to be disassembled, only one bolt needs to be removed from the mounting cylinder corresponding to each wheel to detach the connecting column. The shock absorber rod and cylinder can then be removed. When installing the mounting cylinder, the shock absorber cylinder and rod are placed inside, and the connecting column is then inserted. The bolt is then connected to the threaded groove to connect the connecting column to the limiting block. The limiting groove prevents the limiting block from disengaging from the sliding groove, thus preventing the connecting column from disengaging from the mounting cylinder. This completes the installation of the mounting cylinder and the damping device, avoiding the need to repeatedly remove and install multiple bolts for each wheel, thereby improving work efficiency.

[0009] Optionally, each of the four connecting columns is rotatably connected with a plurality of evenly distributed ball bearings, one end of which is in close contact with the inner sidewall of the mounting cylinder.

[0010] By adopting the above technical solution, the ball bearings are used to reduce the friction between the connecting column and the mounting cylinder, thereby reducing equipment wear.

[0011] Optionally, the lower inner sidewalls of the four mounting cylinders are provided with limiting rings that cooperate with the shock absorber cylinders, the bottom ends of the four connecting columns are provided with positioning grooves, and the top ends of the four shock absorber rods are respectively provided with positioning rods that cooperate with the four positioning grooves.

[0012] By adopting the above technical solution, the limiting ring is used to limit the shock absorber cylinder to prevent it from tilting. The positioning groove cooperates with the positioning rod to limit the shock absorber rod to prevent it from swaying or tilting, thereby improving the stability of the equipment.

[0013] Optionally, each of the four connecting columns is fixedly connected with an auxiliary plate that cooperates with the limiting block.

[0014] By adopting the above technical solution, when the mounting cylinder is connected to the connecting column, the auxiliary plate is tightly attached to the top of the limiting block, and the bolt is aligned with the thread groove, thereby facilitating the installation of the equipment and improving work efficiency.

[0015] Optionally, the bottom end of the main body is fixedly connected with multiple reinforcing bars, and the bottom end of the reinforcing bars is provided with a slot.

[0016] By adopting the above technical solution, the reinforcing bar is used to protect the bottom of the main body. When installing or disassembling the equipment, it is convenient to use jacks or hoisting devices to lift the equipment, reducing the probability of damage to the main body.

[0017] (III) Beneficial Effects

[0018] In summary, this utility model has at least one of the following beneficial technical effects:

[0019] This weeding robot uses a shock absorption device. The starting motor drives a threaded rod to rotate, which in turn moves a threaded component and an extension plate. The extension plate then moves the mowing blade to a suitable height for easy mowing. When the device vibrates, the connecting column slides inside the mounting cylinder, causing the shock absorber rod to slide inside the cylinder as well. This causes the shock absorber spring to contract and extend, reducing vibration and the force transmitted through it, thus achieving shock absorption. To disassemble the shock absorption device, only one bolt needs to be removed from the mounting cylinder corresponding to each wheel, allowing the connecting column to detach. The shock absorber rod and cylinder can then be removed. When installing the mounting cylinder, the shock absorber cylinder and rod are placed inside, and the connecting column is inserted. The bolt is then connected to the threaded groove, connecting the connecting column to the limiting block. The limiting groove prevents the limiting block from disengaging from the sliding groove, thus preventing the connecting column from detaching from the mounting cylinder. This completes the installation of the mounting cylinder and shock absorption device, avoiding the need to repeatedly remove and install multiple bolts for each wheel, thereby improving work efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-5A shock-absorbing device for a weeding robot includes a main body 1 and four mounting cylinders 2. Wheels are mounted on the bottom ends of each of the four mounting cylinders 2. A control seat 3 is fixedly connected to the front end of the main body 1. A control groove is formed at the front end of the control seat 3. A threaded rod 4 is rotatably connected inside the control groove. A threaded component 5 is threaded onto the threaded rod 4. One end of the threaded component 5 passes through the control groove and is connected to an extension plate 6. A weeding blade 7 is mounted on the extension plate 6. A motor 8 connected to the threaded rod 4 is mounted on the top end of the control seat 3. Connecting posts 9 are fixedly connected to the four corners of the bottom end of the main body 1. Sliding grooves are formed on each of the four mounting cylinders 2. Two limiting grooves 10 are formed on the inner wall of the through groove. A limiting block 11 is slidably connected between the two limiting grooves 10. A bolt 12 is threadedly connected to the limiting block 11. Four mounting cylinders 2 are respectively sleeved on four connecting columns 9. Each of the four connecting columns 9 has a threaded groove that mates with the bolt 12. Each of the four mounting cylinders 2 has a shock absorber 13 inside. A shock absorber rod 14 is slidably connected inside the shock absorber 13. The top of the shock absorber rod 14 is in close contact with the connecting column 9. A damper 15 that mates with the shock absorber 13 is provided on the shock absorber rod 14. A shock absorber spring 16 is provided between the shock absorber rod 14 and the shock absorber 13. Start motor 8 The threaded rod 4 rotates, which in turn moves the threaded part 5 and the extension plate 6. The extension plate 6 then moves the mowing blade 7, allowing it to reach a suitable height for mowing. When the equipment is subjected to vibration, the connecting column 9 slides inside the mounting cylinder 2, causing the shock absorber 14 to slide inside the shock absorber cylinder 13. This causes the shock absorber spring 16 to contract and extend, reducing the vibration and the force transmitted to the shock absorber spring 16 by the damper 15, thus achieving the purpose of vibration reduction. When the vibration damping device needs to be disassembled, only one bolt 12 needs to be removed from the mounting cylinder 2 corresponding to each wheel. This allows the connecting post 9 to detach from the mounting cylinder 2. At this point, the shock absorber rod 14 and the shock absorber cylinder 13 can be removed. When installing the mounting cylinder 2, the shock absorber cylinder 13 and the shock absorber rod 14 are placed into the mounting cylinder 2, and then the connecting post 9 is inserted into the mounting cylinder 2. At this point, the bolt 12 is connected to the threaded groove to connect the connecting post 9 to the limiting block 11. The limiting slide groove 10 is used to prevent the limiting block 11 from detaching from the sliding through groove, thereby preventing the connecting post 9 from detaching from the mounting cylinder 2. This completes the installation of the mounting cylinder 2 and the shock absorber, thus avoiding the need to repeatedly remove and install multiple bolts 12 for each wheel, thereby improving work efficiency.

[0029] Reference Figure 3 and Figure 4 Each of the four connecting columns 9 is rotatably connected to a number of evenly distributed ball bearings 17. One end of each ball bearing 17 is in close contact with the inner wall of the mounting cylinder 2. The ball bearings 17 are used to reduce the friction between the connecting columns 9 and the mounting cylinder 2, thereby reducing equipment wear.

[0030] Reference Figures 3-5The lower inner sidewalls of the four mounting cylinders 2 are provided with limiting rings 18 that cooperate with the shock absorber cylinders 13. The bottom ends of the four connecting columns 9 are provided with positioning grooves. The top ends of the four shock absorber rods 14 are respectively provided with positioning rods 19 that cooperate with the four positioning grooves. The limiting rings 18 are used to limit the shock absorber cylinders 13 to prevent the shock absorber cylinders 13 from tilting. The positioning grooves cooperate with the positioning rods 19 to limit the shock absorber rods 14 to prevent the shock absorber rods 14 from shaking or tilting, thereby improving the stability of the equipment.

[0031] Reference Figure 3 and Figure 4 Each of the four connecting columns 9 is fixedly connected with an auxiliary plate 20 that cooperates with the limiting block 11. When the mounting cylinder 2 is connected to the connecting column 9, the auxiliary plate 20 is pressed against the top of the limiting block 11. At this time, the bolt 12 is aligned with the thread groove, so as to facilitate the installation of the equipment and improve work efficiency.

[0032] Reference Figure 2 Multiple reinforcing bars 21 are fixedly connected to the bottom of the main body 1. The bottom of the reinforcing bars 21 is provided with a slot. The reinforcing bars 21 are used to protect the bottom of the main body 1. When installing or disassembling the equipment, it is convenient to use jacks or hoisting devices to lift the equipment, reducing the probability of damage to the main body 1.

[0033] In summary, the working principle and process of the shock absorption device for this weeding robot are as follows: During use, the motor 8 is first started, driving the threaded rod 4 to rotate. The threaded rod 4 then moves the threaded component 5 and the extension plate 6. The extension plate 6 moves the mowing blade 7, allowing it to reach a suitable height for mowing. When the device is subjected to vibration, the connecting column 9 slides inside the mounting cylinder 2, causing the shock-absorbing rod 14 to slide inside the shock-absorbing cylinder 13. This causes the shock-absorbing spring 16 to contract and extend, thus affecting the damper 15. To reduce vibration and the power transmitted to the shock absorber spring 16, the shock absorber is disassembled. When disassembly is required, only one bolt 12 needs to be removed from the mounting cylinder 2 corresponding to each wheel to detach the connecting column 9 from the mounting cylinder 2. At this time, the shock absorber rod 14 and the shock absorber cylinder 13 can be removed. When installing the mounting cylinder 2, the shock absorber cylinder 13 and the shock absorber rod 14 are placed into the mounting cylinder 2, and then the connecting column 9 is inserted into the mounting cylinder 2. The bolt 12 is then connected to the threaded groove to connect the connecting column 9 to the limiting block 11. The limiting groove 10 is used to prevent the limiting block 11 from disengaging from the sliding groove, thereby preventing the connecting column 9 from disengaging from the mounting cylinder 2. This completes the installation of the mounting cylinder 2 and the shock absorber, thus avoiding the need to repeatedly disassemble and assemble multiple bolts 12 for each wheel, thereby improving work efficiency. The ball bearing 17 is used to reduce the friction between the connecting column 9 and the mounting cylinder 2, thereby reducing equipment wear. The limiting ring 18 is used to limit the shock absorber cylinder 13 to prevent it from tilting. The positioning groove cooperates with the positioning rod 19 to limit the shock absorber rod 14 to prevent it from wobbling or tilting, thereby improving equipment stability. When the mounting cylinder 2 is connected to the connecting column 9, the auxiliary plate 20 is pressed tightly against the top of the limiting block 11. At this time, the bolt 12 is aligned with the thread groove, thereby facilitating equipment installation and improving work efficiency. The reinforcing bar 21 is used to protect the bottom of the main body 1. During equipment installation and disassembly, it is convenient to use jacks or hoisting devices to lift the equipment, reducing the probability of damage to the main body 1.

[0034] The lawnmowers described in this application are based on mature technology available on the market and can be selected according to needs.

[0035] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
