6results about How to "Improve mowing effect" patented technology

The application discloses a cutter head protection assembly and a mower, and relates to the technical field of the mower. The cutter head protection assembly comprises a protection piece, the protection piece is connected to the mower and located at the circumferential side of the cutter head, an included angle is formed between the extension surface of the protection piece and the cutting plane of the cutter head, and the protection piece is arranged in the extension direction of the mower. In the axial direction of the cutter head, the side of the protection piece away from the mower comprises a protection end, and a preset interval is formed between the protection end and the landing surface of the mower, so that the protection piece can shield the cutter head and prevent unintended objects from contacting or approaching the cutter head. The cutter head protection assembly disclosed by the application can improve the protection of the cutter head, reduce the risk of injury to the user, and improve the mowing effect.

This application discloses a lawn mowing device and a lawn mowing robot, relating to the field of garden robot technology. The lawn mowing device includes: a linkage mechanism comprising a first connecting seat, a second connecting seat, and at least one link. The first connecting seat is configured to be connected to the main frame of the lawn mowing robot. One end of the link is rotatably connected to the first connecting seat, and the other end of the link is rotatably connected to the second connecting seat. The link is configured to rotate relative to the first connecting seat under the influence of gravity and external ground forces, and to cause the second connecting seat to float in a first direction. A lawn mowing mechanism is connected to the second connecting seat. The lawn mowing device and lawn mowing robot provided by this application can reduce the probability of missed mowing, over-mowing, or scraping the ground during the lawn mowing process.

The utility model relates to a mowing machine and aims to solve the technical problem that the existing mowing machine is poor in adaptability on uneven road surfaces and damages lawns and the mowing machine. The mower comprises a shell, a mowing unit and a pull-up piece, the mowing unit and the pull-up piece are both arranged on the shell, the mowing unit comprises a bearing frame and a cutting assembly arranged on the bearing frame, and the pull-up piece is connected to the bearing frame so as to apply pull force from bottom to top to the bearing frame. The mowing machine can always bear pulling force from bottom to top when working on a lawn, and the design is beneficial for stabilizing movement of the mowing unit and further reducing pressure on the lawn; meanwhile, the bearing frame can rotate along with the terrain of the lawn, the inflexibility of a traditional rigid structure is overcome, and local compaction and damage caused by uneven pressure distribution of the lawn mower under the uneven lawn are avoided.

This invention discloses a lawnmower for gardens, relating to the field of lawnmowing technology. It includes a housing, on which a mowing assembly and a driving assembly are mounted. The driving assembly moves the lawnmower across the grass. The mowing assembly includes a mowing motor installed within the housing, with a fan disc and mowing blades mounted on the motor's drive shaft. Both the fan disc and the mowing blades are located at the bottom of the housing, with the fan disc's vertical height exceeding that of the mowing blades. A retaining ring surrounds the fan disc and the mowing blades at the bottom of the housing. When the mowing motor drives the fan disc and the mowing blades to rotate synchronously, a semi-enclosed airflow channel is formed within the retaining ring of the housing. The airflow generated by the fan disc partially counteracts the upward negative pressure generated by the mowing blades. This invention solves the problem in existing technologies where grass blades flatten before cutting due to the negative pressure of the blades, resulting in poor cutting performance.

This application relates to a ride-on lawnmower and its dual-blade chassis mechanism, including a blade disc and two cutting blade assemblies. Each cutting blade assembly includes a mounting base, a rotating shaft, blades, a locking element, and a rotation-limiting element. The blade disc has two mounting slots, and the mounting base is detachably fixed within these slots. The rotating shaft is rotatably connected to the mounting base, and the locking element locks the rotating shaft and blades. The rotation-limiting element includes a fixing block, a insertion rod, and an adjusting rod. The outer wall of the mounting base has several inner grooves, and the fixing block is detachably connected to one of these grooves. The adjusting rod coaxially fixes one end of the insertion rod. The fixing block has a threaded hole into which the adjusting rod is threaded, with its end protruding and having a cross-shaped groove. The mounting base has a movable slot for the insertion rod to enter, and the rotating shaft has a slot for matching the insertion rod. An adjustment gap is left between the fixing block and the bottom wall of the inner grooves, ensuring the insertion rod remains within the movable slot. When changing blades, rotating the adjusting rod causes the insertion rod to insert into the slot, limiting rotation and preventing the two blades from moving together, thus improving safety. The detachable fixing block facilitates the installation and removal of the rotation-limiting element.

The utility model discloses an anti-winding intelligent mower which comprises a frame body walking mechanism, a cutting mechanism and an adjusting piece, the walking mechanism comprises a driving device, a driving shaft and a protective sleeve, the driving device is installed on the frame body and connected to the driving shaft so as to drive the driving shaft to rotate, driving wheels are arranged at the two ends of the driving shaft, and the protective sleeve is arranged on the periphery of the driving shaft in a sleeving mode. The cutting mechanism comprises a shell, a cutter part and a driving part, the shell is mounted on the frame, the driving part is mounted in the shell, the cutter part is arranged on the outer side of the shell, one end of the driving part is connected to the cutter part so as to drive the cutter part to rotate, the adjusting part is mounted on the driving part, one end of the adjusting part is connected to the cutter part, and the other end of the adjusting part is connected to the cutter part. Therefore, the vertical height of the cutter part is adjusted. According to the technical scheme, the influence of weeds on advancing of the mower can be effectively avoided, meanwhile, adaptability is high, and the mower can be suitable for different mowing environments.
