Technical Field
[0001] The utility model relates to the field of lawn mowers, in particular to a lawn mower. Background Art
[0002] In the prior art, when a user uses a push-type lawn mower to mow grass, a lot of grass juice will seep out from the cut grass. The user will pass through these grasslands when using the lawn mower, resulting in the user's shoes and trouser legs being stained with grass juice, dew and muddy water. Therefore, after using the push-type lawn mower to mow grass, the shoes need to be washed. This makes it necessary for most users to wear waterproof shoes and roll up their trouser legs to carry out the mowing operation, which greatly affects the user experience. Summary of the Utility Model
[0003] In order to overcome the deficiency that when a user uses a push-type lawn mower to mow grass in the prior art, the user's shoes and trouser legs will be stained with grass juice, dew and muddy water on the grassland, the utility model provides a lawn mower, which can solve the problem that when a user uses a push-type lawn mower to mow grass, the user's shoes and trouser legs will be stained with grass juice, dew and muddy water on the grassland.
[0004] To achieve the above purpose, the utility model adopts the following technical scheme: a lawn mower, including a body, a traveling wheel connected to the body for supporting the body and enabling it to travel on the grassland, and a push rod for holding and pushing the body. A mowing device is provided at the bottom of the body, and a ground roller for pressing grass is provided behind the mowing device, and a water-absorbing member is provided on the surface of the ground roller.
[0005] After adopting the above technical scheme, the utility model has the following advantages: by arranging a ground roller behind the mowing device at the bottom of the lawn mower and arranging a water-absorbing member on the surface of the ground roller, after the grass juice flows out after the mowing device finishes mowing the weeds, the user pushes the lawn mower forward, so that the water-absorbing member on the ground roller absorbs the grass juice, which can avoid the grass juice flowing out after the mowing device finishes mowing the weeds from staining the user's shoes or trouser legs, and can also avoid the dew or muddy water on the grassland from staining the user along with the weeds to a certain extent, improving the user experience, and making the user more worry-free when pushing the body to mow grass on the grassland through the push rod, without having to worry about the liquid on the grassland staining oneself.
[0006] Further, the traveling wheel includes two rear wheels, the ground roller is located between the two rear wheels, and the lowest height of the ground roller is not lower than the lowest height of the traveling wheel.
[0007] Adopting the foregoing technical scheme, by arranging the ground roller between the two rear wheels and the lowest height of the ground roller is not lower than the lowest height of the traveling wheel, the ground roller will not affect the rolling of the traveling wheel.
[0008] Further, the ground roller is vertically movably arranged on the body.
[0009] With the foregoing technical solution, when the ground roller encounters a stone or a small mound, the ground roller can avoid and cross the obstacle through its floating characteristics, preventing the lawn mower from getting stuck.
[0010] Furthermore, the surface of the water-absorbing member is a porous structure and there are voids inside, or, the material of the water-absorbing member is a water-absorbing sponge.
[0011] With the foregoing technical solution, the surface of the water-absorbing member is a porous structure. When a liquid comes into contact with the surface of the water-absorbing member, due to the action of van der Waals forces or hydrogen bonds, the liquid will be adsorbed onto the surface of the water-absorbing member. Then, due to the voids inside the water-absorbing member, the liquid will be adsorbed into the inside of the water-absorbing member and stored due to capillary action. By using a water-absorbing sponge as the water-absorbing member, on the one hand, the usage cost is reduced, and on the other hand, the durability is increased.
[0012] Furthermore, the rolling direction of the ground roller is the same as the traveling direction of the lawn mower; the length of the ground roller is greater than or equal to the cutting diameter of the mower.
[0013] With the foregoing technical solution, by setting the rolling direction of the ground roller to be the same as the traveling direction of the lawn mower, the liquid on the grass can be absorbed more efficiently, protecting the user from being contaminated by liquids such as grass juice; by setting the length of the ground roller to be greater than or equal to the cutting diameter of the mower, the cut weeds can be compacted on the grass by the ground roller, and the grass juice on them can be fully absorbed, protecting the user from being contaminated by liquids such as grass juice.
[0014] Furthermore, a connecting member is provided at the bottom of the fuselage, the ground roller is rotatably connected to the connecting member, and the connecting member is detachably connected to the ground roller and / or the fuselage.
[0015] With the foregoing technical solution, through the detachable connection between the connecting member and the ground roller and / or the fuselage, the water-absorbing member on the ground roller can recover its initial water-absorbing performance through cleaning and drying, increasing the number of times of reuse and being more environmentally friendly and efficient.
[0016] Furthermore, the water-absorbing member and the ground roller are detachably connected.
[0017] With the foregoing technical solution, through the detachable connection between the water-absorbing member and the ground roller, the water-absorbing member can be separately cleaned and dried, etc., while the ground roller can separately perform the work of compacting the grass, making it more efficient and convenient.
[0018] Furthermore, a collecting device is provided on the fuselage of the ground roller, which can collect the water sucked into the ground roller.
[0019] Adopting the foregoing technical solution, by providing a collection device on the body, the water absorption capacity of the water absorption member can be increased. Because when the water absorption member is gradually saturated, the collection device collects the water absorbed in the water absorption member into the container, enabling the water absorption member to continue the water absorption work, increasing the total water absorption amount, and collecting grass juice, dew, and muddy water, which can be used to irrigate other crops and provide rich nutritional value.
[0020] Further, the collection device includes a liquid storage container provided on one side of the ground roller close to the cutter, and a liquid scraping blade is provided between the liquid storage container and the ground roller.
[0021] Adopting the foregoing technical solution, by providing a liquid scraping blade between the liquid storage container and the ground roller, the saturated water on the water absorption member can be scraped out by the liquid scraping blade and flow along the liquid scraping blade into the liquid storage container. This solution has a simple structure and lower implementation cost.
[0022] Further, the collection device includes an air absorption device provided inside the body. A water scraping member is provided between the air absorption device and the ground roller, and the water scraping member is provided on the side of the ground roller close to the mower. The water scraping member is of a semi-closed structure with an open end facing the ground roller, and the air absorption device is connected to the closed end of the water scraping member through a pipeline. When the water absorption member on the ground roller inhales liquid and expands, the water scraping member can abut against the water absorption member.
[0023] Adopting the foregoing technical solution, by providing an air absorption device inside the body and a water scraping member between the air absorption device and the ground roller, after the water absorption machine on the ground roller is saturated, it can abut against the water scraping member to extrude the liquid. Subsequently, under the activation of the air absorption device, the liquid is absorbed into the interior, and a certain amount of cut weeds can also be absorbed, preventing the weeds from sticking to the water absorption member and affecting the water absorption performance of the water absorption member.
