Abstract
Description
Technical Field
[0001] This utility model relates to the field of grass trimmer technology, and in particular to a novel intelligent multi-head grass trimmer. Background Technology
[0002] A lawn mower is a mechanical tool used to trim lawns and remove weeds. Its core working principle is to use a motor to drive a high-speed rotating nylon rope or blade to cut the grass.
[0003] Existing grass cutters are generally equipped with a single set of cutters for cutting grass. However, if the grass density is too high, a single cut cannot guarantee that the grass will be completely cut, resulting in uneven heights after cutting. Utility Model Content
[0004] This utility model discloses a novel intelligent multi-head grass cutter, which aims to solve the technical problem that if the grass density is too high, a single cut cannot guarantee complete cutting of the grass, resulting in uneven heights after cutting.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A novel intelligent multi-head lawn mower includes a main frame, and further includes: a housing 1, with a damping bearing seat fixedly connected to its top outer wall, and the bottom end of the main frame rotatably connected to the damping bearing seat; a limiting mechanism fixedly connected to the top outer wall of the housing 1 and located on one side of the damping bearing seat; an intelligent monitoring mechanism installed on one side of the housing 1; two housing 2, symmetrically fixedly connected to the bottom inner wall of the housing 1; two rotating rods rotatably connected to the center of the two housing 2, and each rotating rod has multiple blades fixedly connected at equal intervals at its bottom end, with a different number of blades on the two rotating rods; and a drive mechanism for driving the two rotating rods to rotate synchronously.
[0007] One end of the main frame is fixedly connected to a handle, and the drive mechanism includes: two synchronous pulleys, which are respectively fixedly connected to the top outer wall of two rotating rods, and synchronous belts are respectively sleeved on the two synchronous pulleys; and a gear, which is fixedly connected to the top outer wall of one of the rotating rods.
[0008] The drive mechanism further includes: a first gear, which is rotatably connected to the inner wall of the top of the first housing and meshes with a second gear; and a motor, which is fixedly installed on the outer wall of the top of the first housing and whose output end is fixedly connected to the first gear.
[0009] By setting two sets of blades, the cutting effect will be different based on the number of blades in the two sets. The blades with more blades can be placed at the rear. During the grass cutting process, the front blades will coarsely cut and the rear blades will finely cut, which will reduce the wear of the blades and the probability of grass getting mixed in. If the grass is not dense when cutting, the main frame can rotate in the damping bearing seat to increase the single cutting area and optimize the cutting efficiency.
[0010] In a preferred embodiment, the limiting mechanism includes: a square support, fixedly connected to the outer circumference of the main frame, and the square support has limiting holes on multiple outer walls; a limiting rod, movably inserted into the limiting holes, and a side plate two is fixedly connected to one outer wall of the rod, and a handle two is fixedly connected to one outer wall of the side plate two.
[0011] The limiting mechanism further includes: a side plate one, which is fixedly connected to the top outer wall of the housing one, and the limiting rod is movably inserted into the side plate one; a spring, which is sleeved on the outer periphery of the limiting rod, and its two ends are fixedly connected to the side plate one and the side plate two respectively.
[0012] By setting a limiting mechanism, the stability of the main frame position can be ensured by inserting a limiting rod into the corresponding limiting hole, thus preventing changes in the relative position of the main frame and the casing during grass cutting and ensuring stability during the grass cutting process.
[0013] In a preferred embodiment, a mounting bracket is fixedly connected to the outer circumference of the main frame, and a display screen is fixedly connected to one outer wall of the mounting bracket.
[0014] The intelligent monitoring mechanism includes: an arc-shaped slide groove, which is set on the inner wall of one side of the housing, and a damping slide is movably engaged in the arc-shaped slide groove; and a camera, which is fixedly installed on the damping slide and electrically connected to the display screen.
[0015] Equipped with a camera and display screen, the camera can monitor the area in front of the grass in real time during the mowing process, and the display screen can show the monitoring images, reducing the probability of blade damage. At the same time, the camera installation position can be changed by moving the damping carriage, so as to adapt to the horizontal or vertical use of the two sets of blades.
[0016] As described above, a novel intelligent multi-head mower includes a main frame and further comprises: a housing 1, with a damping bearing seat fixedly connected to its top outer wall, and the bottom end of the main frame rotatably connected to the damping bearing seat; a limiting mechanism fixedly connected to the top outer wall of the housing 1 and located on one side of the damping bearing seat; an intelligent monitoring mechanism installed on one side of the housing 1; two housing 2, symmetrically fixedly connected to the bottom inner wall of the housing 1; two rotating rods rotatably connected to the center positions of the two housing 2, and each rotating rod has multiple blades fixedly connected at equal intervals at its bottom end, with a different number of blades on the two rotating rods; and a drive mechanism for driving the two rotating rods to rotate synchronously. The novel intelligent multi-head mower provided by this utility model has the technical effect of reducing blade wear and the probability of grass entanglement, while simultaneously optimizing cutting efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] The present invention discloses a novel intelligent multi-head lawn mower, which is mainly used in the scenario of grass trimming.
[0024] Reference Figure 1 and Figure 2A novel intelligent multi-head lawn mower includes a main frame 2, and further includes: a housing 7, the top outer wall of which is fixedly connected to a damping bearing seat 6, and the bottom end of the main frame 2 is rotatably connected to the damping bearing seat 6; a limiting mechanism 5, fixedly connected to the top outer wall of the housing 7 and located on one side of the damping bearing seat 6; an intelligent monitoring mechanism 8, installed on one side of the housing 7; two housings 9, symmetrically fixedly connected to the bottom inner wall of the housing 7; and two rotating rods 13, rotatably connected to the center of the two housings 9, and each rotating rod 13 has multiple blades 14 fixedly connected at equal intervals at its bottom end, with the number of blades 14 on the two rotating rods 13 being different. The drive mechanism is used to drive the two rotating rods 13 to rotate synchronously. Based on the different numbers of the two sets of blades 14, the cutting effect is also different. The more blades 14 there are, the finer the cut. When cutting grass, the more numerous blades 14 can be placed at the rear. During the grass cutting process, the front blades 14 make coarse cuts and the rear blades make fine cuts, which can ensure the cutting effect on dense grass, while reducing the wear of the blades 14 and the probability of grass getting mixed in. If the grass is not dense when cutting, both sets of blades 14 can ensure a clean cut, which allows the main frame 2 to rotate in the damping bearing seat 6, driving the two sets of blades 14 to be set horizontally, increasing the single cutting area and optimizing the cutting efficiency.
[0025] Reference Figure 2 In a preferred embodiment, a handle 1 is fixedly connected to one end of the main frame 2, and the drive mechanism includes: two synchronous pulleys 16, which are respectively fixedly connected to the top outer wall of two rotating rods 13, and synchronous belts 15 are respectively sleeved on the two synchronous pulleys 16; and a gear 12, which is fixedly connected to the top outer wall of one of the rotating rods 13.
[0026] Reference Figure 2 In a preferred embodiment, the drive mechanism further includes: a gear 11, which is rotatably connected to the inner wall of the top of the housing 7 and meshes with a gear 12; and a motor 10, which is fixedly installed on the outer wall of the top of the housing 7 and whose output end is fixedly connected to the gear 11.
[0027] Reference Figure 1 In a preferred embodiment, a mounting bracket 3 is fixedly connected to the outer circumference of the main frame 2, and a display screen 4 is fixedly connected to one side of the outer wall of the mounting bracket 3.
[0028] Reference Figure 4In a preferred embodiment, the intelligent monitoring mechanism 8 includes: an arc-shaped slide 801, which is disposed on the inner wall of one side of the housing 7, and a damping slide 802 is movably engaged in the arc-shaped slide 801; and a camera 803, which is fixedly installed on the damping slide 802 and electrically connected to the display screen 4. During the grass cutting process, the camera 803 can monitor the area in front of the grass in real time, and the monitoring image can be displayed on the display screen 4. If foreign objects such as stones appear in front, image information can be quickly obtained, and the blade 14 can be prevented from hitting the stones, reducing the probability of damage to the blade 14. At the same time, through the setting of the arc-shaped slide 801, the damping slide 802 can be moved inside to change the installation position of the camera 803, thereby adapting to the horizontal or vertical use of the two sets of blades 14.
[0029] Reference Figure 3 In a preferred embodiment, the limiting mechanism 5 includes: a square support 502, which is fixedly connected to the outer circumferential wall of the main frame 2, and the square support 502 has limiting holes 501 on multiple outer walls; a limiting rod 504, which is movably inserted into the limiting holes 501, and a side plate 507 is fixedly connected to one outer wall of the rod, and a handle 506 is fixedly connected to one outer wall of the side plate 507.
[0030] Reference Figure 3 In a preferred embodiment, the limiting mechanism 5 further includes: a side plate 503, fixedly connected to the top outer wall of the housing 7, and a limiting rod 504 movably inserted into the side plate 503; a spring 505, sleeved on the outer periphery of the limiting rod 504, and its two ends fixedly connected to the side plate 503 and the side plate 507 respectively. By stretching the spring 505 with the handle 506, the limiting rod 504 can be disengaged from the limiting hole 501, thereby allowing the square support 502 to rotate. After the main frame 2 is rotated and adjusted in position within the damping bearing seat 6, the limiting rod 504 is re-inserted into the corresponding limiting hole 501 under the rebound action of the spring 505, thus ensuring the stability of the position of the main frame 2 and preventing changes in the relative position of the main frame 2 and the housing 7 during grass cutting, ensuring stability during grass cutting.
[0031] Working principle: The cutting effect is different based on the different number of the two sets of blades 14. The more blades 14 there are, the finer the cut. When cutting grass, the more blades 14 can be placed at the rear. During the cutting process, the front blades 14 coarsely cut and the rear blades finely cut, which can ensure the cutting effect on dense grass, while reducing the wear of the blades 14 and the probability of grass getting mixed in. If the grass is not dense when cutting, both sets of blades 14 can ensure a clean cut, which allows the main frame 2 to rotate in the damping bearing seat 6, driving the two sets of blades 14 to be set horizontally, increasing the single cutting area and optimizing the cutting efficiency.
[0032] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
