Description

Technical Field

[0001] The invention relates to the technical field of turf maintenance, and in particular to an anti-collision device at a mobile end of a turf maintenance station. Background Art

[0002] The turf maintenance station is a mechanical tool that integrates functions such as lawn mowing, vegetation, drilling, and fertilizing. The blade drives the tool to rotate to cut the grass, and then the fan blades and other blowing mechanisms transfer the grass clippings or fallen leaves to the grass collection box for collection. The drilling device is used to drill holes and fertilize at the same time.

[0003] During the operation of the existing turf maintenance station mobile terminal, the anti-collision device detects obstacles and determines the height of the obstacles, thereby controlling the lifting and lowering of the blade to climb over the obstacles. The method is simple and can avoid damage to the blade. Although the anti-collision device can well complete the anti-collision work, the function is relatively single and is not enough to meet the requirements of the existing turf maintenance station for functional integration.

[0004] In view of this, it is necessary to propose a new technical solution to solve the above technical problems. Summary of the invention

[0041] Embodiment 1

[0042] See Figures 1-9 As shown, the anti-collision device of the turf maintenance station mobile terminal includes a chassis 1, an anti-collision mechanism 2 and a detection mechanism 3. The detection end of the detection mechanism 3 faces the anti-collision mechanism 2 and is used to detect the rotation angle of the anti-collision mechanism 2. It further includes a driving mechanism 4 and a mounting bracket 5. The mounting bracket 5 is mounted on the chassis 1, and the driving mechanism 4, the detection mechanism 3 and the anti-collision mechanism 2 are mounted on the mounting bracket 5. The output end of the driving mechanism 4 is connected to the anti-collision mechanism 2 and is used to drive the anti-collision mechanism 2 to rotate around the output end of the driving mechanism 4.

[0043] The root of the grass is its foundation, and the health of the root determines the overall health of the grass. General users will comb the grass roots in spring. However, due to long-term trampling, the soil in some parts of the lawn may become very compact, and air, nutrients and moisture are not easily permeable. In addition, the root system of the lawn grass is developed, and a dense root network has been formed after a long time of accumulation, which will affect the permeability of the soil. In the prior art, the work of raking the grass is usually carried out manually, which requires a lot of time and has a large labor intensity.

[0044] With the setting of the driving mechanism 4, the anti-collision mechanism 2 can rotate around the output end of the driving mechanism 4. On the one hand, the anti-collision mechanism 2 can extend deep into the turf to loosen the roots of the thick turf. After loosening the grass roots, the soil stability can be enhanced, and the growth of the turf can be promoted. And through the present invention, the roots of the turf can be loosened regularly, thus avoiding the formation of a dense root network in the turf.

[0045] On the other hand, it can bring the fallen leaves deep in the turf to the surface of the turf and send them into the grass collection box by the grass collection mechanism for collection and treatment.

[0046] It should be noted that when the driving mechanism 4 drives the anti-collision mechanism 2 to rotate, the anti-collision mechanism 2 rotates around the output end of the driving mechanism 4, that is, the lower end of the anti-collision member 22 of the anti-collision mechanism 2 moves in a reciprocating arc, stirring when extending into the turf to loosen the roots of the turf. The structure is simple and has multiple functions, meeting the requirements of the existing turf maintenance station for functional integration.

[0047] It can be understood that, as a preferred embodiment, the mounting frame 5 of this embodiment is composed of two mounting plates, which are respectively arranged on both sides of the chassis 1. The driving mechanism 4 of this embodiment is installed on one mounting plate, the detection mechanism 3 is installed on the other mounting plate, and both ends of the anti-collision mechanism 2 are respectively installed on the inner sides of the two mounting plates.

[0048] In a further specific embodiment, a transmission mechanism 6 is further included. The transmission mechanism 6 includes two gear sets 61 and a first rotating shaft 62. It should be noted that one gear set 61 is respectively installed at both ends of the mounting frame 5, that is, one gear set 61 is respectively installed on each mounting plate. Both ends of the first rotating shaft 62 are respectively connected to one gear set 61. The input end of one gear set 61 is connected to the output end of the driving mechanism 4, and the anti-collision mechanism 2 is installed at the output end of the gear set 61.

[0049] The anti-collision mechanism 2 is driven to rotate through the gear transmission method, so as to realize the functions of turf combing and fallen leaf cleaning. Through the first rotating shaft 62, the driving mechanism 4 can drive the two gear sets 61 to rotate simultaneously.

[0050] In a further specific embodiment, the transmission mechanism 6 further includes a protection component 63, and the protection component 63 is arranged between two gears of one of the gear sets 61.

[0051] With the setting of the protection component 63, the transmission mechanism 6 and the driving mechanism 4 are protected. When being violently impacted, the protection component 63 can interrupt the transmission between the gear sets 61, preventing damage to the transmission mechanism 6 and the driving mechanism 4 when being violently impacted. The structure is simple and has strong stability.

[0052] In a further specific embodiment, the protection component 63 includes a first magnetic member 631 and a second magnetic member 632. The first magnetic member 631 is meshed with or coaxially arranged with a gear in the gear set 61, and the second magnetic member 632 is meshed with or coaxially arranged with a gear in the gear set 61. The first magnetic member 631 and the second magnetic member 632 perform non-contact power transmission.

[0053] As a preferred embodiment, the first magnetic member 631 of the present embodiment includes a gear. A plurality of mounting grooves are arrayed around the axis on the surface of the gear, and a magnet is arranged in each mounting groove. The second magnetic member 632 is a magnet disk. The magnets on the gear and the magnet disk can either repel each other with the same pole or attract each other with opposite poles. In a magnetic connection manner, the first magnetic member 631 drives the second magnetic member 632 to rotate.

[0054] It should be noted that the first magnetic member 631 is meshed with a gear in the gear set 61, and the second magnetic member 632 is coaxially arranged with a gear in the gear set 61. That is, the gear set 61 drives the first magnetic member 631 to rotate through meshing, the first magnetic member 631 drives the second magnetic member 632 to rotate through magnetism, and the second magnetic member 632 drives another gear to rotate, thereby driving the anti-collision mechanism 2 to rotate.

[0055] When receiving a violent impact, as long as the impact force received is greater than the magnetic force between the first magnetic member 631 and the second magnetic member 632, then the force transmission between the first magnetic member 631 and the second magnetic member 632 will be reduced or stopped, avoiding excessive impact force and causing wear of the gear set 61.

[0056] Refer to Figure 7 As shown, in a further specific embodiment, a limiting mechanism 7 is further included. The limiting mechanism 7 includes a limiting block 71 and a driving member 72. At least one limiting hole 611 is opened in a gear in one of the gear sets 61. In this embodiment, the number of the limiting holes 611 is one. In other specific embodiments, the number of the limiting holes 611 can also be 6 - 10. The plurality of limiting holes 611 are annularly arrayed around the axis of the gear with the axis of the gear as the origin. The driving member 72 is installed on the mounting frame 5, and the limiting block 71 is installed at the output end of the driving member 72. The transmission mechanism 6 has a transmission state and a limiting state. When the transmission mechanism 6 is in the transmission state, the driving member 72 drives the limiting block 71 to move, so that the limiting block 71 moves away from the limiting hole 611. When the transmission mechanism 6 is in the limiting state, the driving member 72 drives the limiting block 71 to move, so that the limiting block 71 extends into the limiting hole 611 to limit the transmission mechanism 6.

[0057] Through the arrangement of the limiting mechanism 7, during the anti-collision work, the driving member 72 drives the limiting block 71 into the limiting hole 611, so that the transmission mechanism 6 is in a limiting state, the driving mechanism 4 can be fixed, and the anti-collision member 22 rotates around the second rotating shaft 21. When the work of combing grass and cleaning fallen leaves needs to be carried out, the driving member 72 drives the limiting block 71 to withdraw from the limiting hole 611, so that the transmission mechanism 6 is in a transmission state, and the anti-collision member 22 rotates around the gear of the transmission mechanism 6 with the third rotating shaft 23 as the center, and the movement track is in the shape of a rowing motion.

[0058] Refer to Figure 7 As shown, in a further specific embodiment, the limiting mechanism 7 further includes a fixing frame 73, the fixing frame 73 is installed on the mounting frame 5, the first end of the limiting block 71 is rotatably installed on the mounting frame 5, the output end of the driving member 72 is connected to the middle end of the limiting block 71, a limiting pin 711 is arranged at the second end of the limiting block 71, and the driving member 72 drives the limiting pin 711 to enter and exit the limiting hole 611.

[0059] When limiting the transmission mechanism 6, the driving member 72 drives the limiting block 71 with the first end as the origin, and inserts the limiting pin 711 into the limiting hole 611. It should be noted that the driving member 72 is an electromagnet 32. The structure is simple and the stability is strong.

[0060] In a further specific embodiment, the anti-collision mechanism 2 includes a second rotating shaft 21 and a plurality of anti-collision members 22. The two ends of the second rotating shaft 21 are respectively rotatably installed on the mounting frame 5. It should be noted that the two ends of the second rotating shaft 21 in this embodiment are respectively rotatably installed on the two gear sets 61. In other specific embodiments, if the transmission mechanism 6 is not provided, bearings can be respectively arranged at the two ends of the rotating shaft 21, and the rotating shaft 21 is connected to the mounting frame 5 through the bearings. The output end of the driving mechanism 4 is connected to one end of the second rotating shaft 21. It can be understood that the output end of the driving mechanism 4 in this embodiment is connected to the gear set 61, and the gear set 61 drives the second rotating shaft 21 to rotate. It is used to drive the anti-collision member 22 to rotate through the second rotating shaft 21. A through groove 11 is opened on the chassis 1, and the first ends of the plurality of anti-collision members 22 are respectively installed on the second rotating shaft 21, and the second ends of the plurality of anti-collision members 22 respectively penetrate through the through groove 11.

[0061] During the anti-collision work, through the arrangement of the second rotating shaft 21, the anti-collision member 22 rotates with the second rotating shaft 21 as the origin, and in cooperation with the detection mechanism 3, the anti-collision work is completed.

[0062] When performing the work of raking the grass and cleaning the fallen leaves, the driving mechanism 4 and the transmission mechanism 6 drive the anti-collision member 22 to rotate through the second rotating shaft 21. Under the limitation of the position of the anti-collision member 22 by the third rotating shaft 23 and the limiting groove 221, the work of raking the grass and cleaning the fallen leaves is completed.

[0063] Refer to Figure 8 、 9 As shown in the further specific embodiment, the anti-collision mechanism 2 further includes a third rotating shaft 23. A limiting groove 221 is formed in the middle of the anti-collision member 22. Both ends of the third rotating shaft 23 respectively penetrate through the limiting groove 221 and are connected to the mounting bracket 5. Arc-shaped grooves 51 are respectively formed at both ends of the mounting bracket 5. Both ends of the third rotating shaft 23 are respectively arranged in the two arc-shaped grooves 51. Elastic members 52 are respectively installed at both ends of the mounting bracket 5. The first ends of the two elastic members 52 are connected to the mounting bracket 5, and the second ends of the two elastic members 52 are respectively connected to both ends of the third rotating shaft 23.

[0064] When performing the anti-collision work, the anti-collision member 22 slides in the arc-shaped groove 51 through the third rotating shaft 23, that is, the third rotating shaft 23 moves from the leftmost side of the arc-shaped groove 51 to the rightmost side, thereby completing the anti-collision work. It should be noted that the sliding of the anti-collision member 22 referred to in this embodiment means that when the anti-collision member 22 touches an obstacle, the obstacle pushes the bottom of the anti-collision member 22 to move in the through groove 11. Since the anti-collision member 22 rotates around the second rotating shaft 21 during the anti-collision work, the anti-collision member 22 will be in an inclined state. At this time, the elastic member 52 is stretched by the movement of the third rotating shaft 23. After passing over the obstacle, the third rotating shaft 23 returns to the origin under the pulling force of the elastic member 52, that is, returns to the leftmost side of the arc-shaped groove 51. It should be noted that the elastic member 52 in this embodiment is selected as a tension spring. In other specific embodiments, elastic members 52 such as rubber can also be used.

[0065] When performing the work of raking the grass and cleaning the fallen leaves, the elastic member 52 restricts the third rotating shaft 23 to the leftmost side of the arc-shaped groove 51. Therefore, the anti-collision member 22 rotates around the gear of the transmission mechanism 6 with the third rotating shaft 23 as the center through the limiting groove 221 under the drive of the transmission mechanism 6, and the movement trajectory is in the shape of a rowing motion.

[0066] As shown in FIG. 6, in a further specific embodiment, the detection mechanism 3 includes a fork 31, a magnet 32, and an angle sensor 33. The first end of the fork 31 is rotatably installed on the mounting bracket 5. The second end of the fork 31 is installed on the third rotating shaft 23. The magnet 32 is installed on the fork 31. The angle sensor 33 is installed on the mounting bracket 5. The sensing end of the angle sensor 33 faces the magnet 32 and is used to sense the rotation angle of the magnet 32.

[0067] When mowing the lawn, the turf maintenance station detects the height of the front obstacle through the anti-collision device to adjust the height of the mowing blade and protect the blade. The driving member 72 drives the limit pin 711 into the limit hole 611 to limit the rotation of the transmission mechanism 6. The anti-collision member 22 rotates around the second rotating shaft 21. When there is no obstacle, the third rotating shaft 23 leans against the leftmost side of the arc-shaped groove 51 under the pulling force of the tension spring. The fork 31 is also driven to the origin position, and the magnet 32 is also at the origin position. The angle sensor 33 detects that the angle has not changed, indicating that there is no obstacle that cannot be passed in front. When there is an obstacle in front, the obstacle blocks the anti-collision member 22, and the anti-collision member 22 rotates around the second rotating shaft 21. The third rotating shaft 23 slides in the arc-shaped hole, driving the fork 31 to rotate. At this time, the magnet 32 also rotates with the fork 31, and the angle sensor 33 can detect the rotating angle, and then the height of the obstacle can be calculated. Thus, the height of the mowing blade is adjusted to avoid the obstacle.
