Different types of lawn mowers have slightly different working principles. A rotary lawn mower is one side of the lawn mower. The blades are usually driven by an engine or electric motor to rotate at high speed. When the blades come into contact with the grass, they are cut off. This type of lawn mower is suitable for mowing large areas of lawn and is more efficient.

[0003] When the existing lawn mower collection structure collects grass, there may be gaps in the connection between the collection structure and the lawn mower body, which may cause some grass to leak during the collection process. In addition, the grass is relatively fluffy and will take up a lot of space in the collection bin, which causes the collection bin to fill up quickly and requires frequent cleaning and emptying of the collection bin, reducing the continuous working time and collection efficiency of the lawn mower, thereby affecting the use effect.

[0004] Therefore, a grass collecting structure for a lawn mower is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-6 , this utility model provides a technical solution:

[0027] A grass collection structure for a lawn mower includes a mounting frame 1, a harvesting device 2 disposed within the mounting frame 1, a filter assembly 3 fixedly connected to the rear side of the mounting frame 1, the filter assembly 3 including a filter frame 301, a collection assembly 4 fixedly connected to the rear side of the filter frame 301, and handrails 5 fixedly connected to both sides of the collection assembly 4;

[0028] The collecting component 4 includes a collecting bin 401, a suction fan 402, a pressure plate 403 and an electric push rod 404. The collecting bin 401 is fixedly connected to the filter frame 301 on one side close to the filter frame 301. The suction fan 402 is fixedly connected to the rear side of the collecting bin 401 and a screen is provided at the suction end of the suction fan 402. The pressure plate 403 is movably connected to the inside of the collecting bin 401. The electric push rod 404 is fixedly connected to the top of the collecting bin 401. The telescopic end of the electric push rod 404 passes through the collecting bin 401 and is fixedly connected to the top of the pressure plate 403.

[0029] In this embodiment: by setting up a collecting component 4, when the harvesting device 2 cuts the grass, the cut grass will move backward under the action of the forward power of the lawn mower and factors such as airflow, and then the strong suction force generated by the suction fan 402 can suck all the cut grass into the collecting bin 401, avoiding grass leakage during the grass collection process. When the grass in the collecting bin 401 accumulates to a certain level, the electric push rod 404 is started, and its telescopic end will drive the pressure plate 403 to move downward. When the pressure plate 403 moves downward, it will apply pressure to the grass, making the grass more compact, thereby achieving the effect of compacting the collected grass and increasing the storage capacity of the collecting bin 401.

[0030] Specifically, such as Figure 3 As shown, the filter frame 301 is movably connected to the pull-out frame 302 , and the left side of the pull-out frame 302 is fixedly connected to the handle 303 . The first filter screen 304 is fixedly connected to the inside of the pull-out frame 302 .

[0031] Specifically, such as Figure 3 As shown, the filter frame 301 is fixedly connected with a second filter screen 305 and the second filter screen 305 is located in front of the first filter screen 304 . The mesh number of the second filter screen 305 is smaller than that of the first filter screen 304 .

[0032] Specifically, such as Figure 3 As shown, the top of the filter frame 301 is threadedly connected with a fastening screw 306 and the end of the fastening screw 306 is set to an anti-slip material. The end of the fastening screw 306 is tightly fitted with the pull-out frame 302.

[0033] In this embodiment: by setting up the filter component 3, when the harvesting device 2 of the lawn mower cuts the grass, the strong suction force of the suction fan 402 will attract the grass to move backward, and the grass will first pass through the filter frame 301. The second filter screen 305 in the filter frame 301 can perform preliminary filtering on the grass and intercept larger impurities. Then the grass after preliminary filtration continues to move backward. When passing through the first filter screen 304, the first filter screen 304 can further filter out smaller impurities, so that the grass can be double-filtered, effectively preventing the collection bin 401 and the suction fan 402 from being blocked, and ensuring the normal operation of the collection component 4.

[0034] Specifically, such as Figure 6 As shown, the bottom of the collecting bin 401 is rotatably connected to a baffle 6 , and the internal thread of the baffle 6 is connected to a connecting bolt 7 .

[0035] Specifically, such as Figure 6 As shown, a connecting groove 8 is provided at the bottom of the collecting bin 401 , and the connecting groove 8 is used in conjunction with the connecting bolt 7 .

[0036] In this embodiment: through the above arrangement, when the grass in the collecting bin 401 needs to be unloaded, the rotating connected baffle 6 can be easily opened, and by loosening the connecting bolt 7 and rotating the baffle 6, the compacted grass can be unloaded from the bottom of the collecting bin 401, thereby improving the convenience of use.

[0037] Specifically, such as Figure 5 As shown, both sides of the inner wall of the collecting bin 401 are provided with chutes 9 , and both sides of the pressing plate 403 are fixedly connected with sliders 10 , which are slidably connected inside the chutes 9 .

[0038] Specifically, such as Figure 2 As shown, a guide block 11 is fixedly connected to the interior of the mounting frame 1 , and two guide blocks 11 are fixedly connected to the top and bottom of the filter frame 301 respectively.

[0039] In this embodiment: by setting the slide groove 9 and the slider 10, the slider 10 can slide in the slide groove 9, which can provide a stable guide for the up and down movement of the pressure plate 403, and can prevent the pressure plate 403 from deflecting or shaking, ensuring that the compaction work can be carried out stably. By setting the guide block 11, the guide block 11 can guide the grass cut by the harvesting device 2 to flow accurately to the filter frame 301, thereby ensuring that the grass will not splash everywhere, further improving the grass collection effect.

[0040] Working principle: When the lawn mower is started, the harvesting device 2 inside the mounting frame 1 starts working to cut the grass, and then pushes the armrest frame 5 forward. The grass moves backward under the action of the airflow and the forward power of the machine. The guide block 11 guides the cut grass to flow accurately to the filter frame 301. When the grass passes through the filter frame 301, the second filter 305 in the filter frame 301 can perform preliminary filtering on the grass and intercept larger impurities. After the preliminary filtration, the grass will continue to move backward. When it passes through the first filter 304, the first filter 304 can further filter out smaller impurities, and then the strong suction force of the suction fan 402 will suck the double-filtered grass into the collecting bin 401. When the grass in the collecting bin 401 accumulates to a certain level, the electric push rod 404 is started, and its telescopic end will drive the pressure plate 403 to move downward. When the pressure plate 403 moves downward, it will exert pressure on the grass, making the grass more compact. When the grass in the collecting bin 401 needs to be unloaded, the compacted grass can be unloaded from the bottom of the collecting bin 401 by loosening the connecting bolts 7 and rotating the baffle 6.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
