Description

Technical Field

[0001] This utility model relates to the field of grass pusher technology, and more specifically, to a high-performance multi-blade grass pusher. Background Technology

[0002] With the continuous expansion of modern landscaping and the increasing standards of lawn maintenance, commercial and household lawn mowing equipment is facing higher requirements for operating efficiency and quality. As the core equipment for lawn maintenance, the performance of lawn mowers directly affects the aesthetics and maintenance efficiency of lawns.

[0003] Traditional single-blade lawn mowers generally suffer from technical bottlenecks such as low mowing efficiency and insufficient grass clipping when dealing with large areas and high-density lawns, making it difficult to meet the needs of modern lawn maintenance. The flat single blade can only form a single linear cutting trajectory during the rotary cutting process, resulting in an effective cutting length of less than 40% of the total blade length, with a lot of missed cuts. Furthermore, the grass clippings are not easy to collect and centrally process after cutting, which reduces the functionality of the lawn mower. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the problems existing in the prior art, this utility model provides a high-performance multi-blade grass pusher to solve the technical problem of low cutting efficiency of single-blade structures mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-performance multi-blade lawn mower, comprising a lawn mower body, the lawn mower body including a frame, a drive shaft rotatably mounted on the frame, drive plates arrayed on the drive shaft, drive blades circumferentially bent between the drive plates, a mounting device and a cutting blade on the drive plate, a rotating shaft rotatably mounted on the frame, a hub mounted on the rotating shaft, a tire mounted on the hub, a drive gear ring inside the hub, a drive gear cooperating with the drive gear ring on the drive shaft, a mounting device including a mounting plate mounted on the frame, a mounting rod mounted on the mounting plate, a moving block mounted on the mounting rod, a locking groove mounted on the moving block, locking blocks symmetrically sliding on the locking groove, and locking springs between the locking blocks.

[0008] The present invention is further configured such that the mounting rod has a movable groove inside, a movable screw is rotatably disposed in the movable groove, and the movable block is slidably disposed in the movable groove and threadedly connected to the movable screw, which facilitates the adjustment of the position of the cutting blade.

[0009] The present invention is further configured such that a movable plate is slidably provided on the mounting rod, and a movable spring is provided between the movable plate and the mounting plate, which facilitates the contact support of the cutting blade and improves the stability of the cutting blade.

[0010] The present invention is further provided that the frame is provided with a handle, and the handle is provided with a collection box for easy collection of the cut grass.

[0011] The present invention is further configured such that the collection box is provided with plug-in rods at both ends, and the handle is provided with plug-in grooves that cooperate with the plug-in rods, so as to facilitate the installation of the collection box on the handle.

[0012] The present invention is further configured such that the frame is provided with a roller, and the bottom of the collection box is provided with a groove that cooperates with the roller, so as to facilitate the support of the collection box.

[0013] The present invention is further configured such that a support arm is rotatably provided on the frame, the support arm is L-shaped, the idler roller is rotatably provided at one end of the support arm, the frame is provided with a plurality of limiting holes in the circumferential direction, and the support arm is provided with limiting bolts that cooperate with the limiting holes to limit the position and height of the support arm and the idler roller.

[0014] The present invention is further provided that a cover is installed on the hub by bolts to prevent grass from entering the hub and affecting the meshing of the drive gear and the drive ring gear.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a high-performance multi-blade grass pusher, which has the following beneficial effects:

[0017] 1. By rotating the hub and tires, the hub drives the drive gear ring to rotate, which in turn drives the drive gear to rotate. The drive gear then drives the drive shaft to rotate, which in turn drives the drive plate and drive blades to rotate, thus folding and cutting the grass. At the same time, the cutting blades work together to cut the grass, improving the cutting effect and enhancing the practicality of the grass pusher.

[0018] 2. The cutting blade is fixed on one side by a moving spring and a moving plate, and the other side of the cutting blade is fixed by a snap-fit ​​spring and snap-fit ​​block on the mounting rod. Rotating the moving screw drives the moving block to move in the moving groove, adjusting the position of the cutting blade while changing the deformation of the moving spring, so that the cutting blade is installed stably.

[0019] 3. By setting up a collection box, it is easy to collect the trimmed grass, realizing the multi-functionality and ease of use of the grass pusher. The cooperation between the plug rod and the plug slot facilitates the installation of the collection box. The cooperation between the limit bolt and the limit hole facilitates the adjustment of the height of the idler roller. The cooperation between the idler roller and the slot provides support and limit for the collection box. Attached Figure Description

[0031] In this embodiment, during use, the cutting blade 6 is installed. The cutting blade 6 has a mounting hole that matches the mounting rod 13. The size of the moving plate 20 is larger than the size of the mounting hole. The cutting blade 6 is fitted onto the mounting rod 13, and the locking block 16 is pressed into the locking groove 15. The locking block 16 presses against the locking spring 17. After the cutting blade 6 passes through the locking block 16, one side abuts against the moving plate 20. The locking block 16 extends under the elastic force of the locking spring 17 and is restricted to the other side of the cutting blade 6. The moving screw 19 is rotated, and the moving screw 19 drives the moving block 14 in the moving groove 18. The internal movement adjusts the position of the moving block 14 and the locking block 16, causing the cutting blade 6 to press against the moving plate 20 and the moving spring 21. While adjusting the position of the cutting blade 6, the installation stability of the cutting blade 6 is also adjusted. The frame 2 is moved by the handle 22. When the frame 2 moves, the hub 8 rotates, which drives the drive gear ring 10 to rotate. The drive gear ring 10 drives the drive gear 11 and the drive shaft 3 to rotate. The drive shaft 3 drives the drive plate 4 and the drive blade 5 to rotate, bending and cutting the grass. The grass is then cut in conjunction with the cutting blade 6.

[0034] In summary, during use or operation of the overall equipment: When in use, install the cutting blade 6, which has mounting holes adapted to the mounting rod 13. The size of the moving plate 20 is larger than the size of the mounting holes. Place the cutting blade 6 onto the mounting rod 13 and press the locking block 16 into the locking groove 15. The locking block 16 presses against the locking spring 17. After the cutting blade 6 passes through the locking block 16, one side abuts against the moving plate 20. The locking block 16 extends under the elastic force of the locking spring 17, confining it to the other side of the cutting blade 6. Rotate the moving screw 19, which drives the moving block 14 to move... The moving part moves within the groove 18, adjusting the position of the moving block 14 and the locking block 16, causing the cutting blade 6 to press against the moving plate 20 and the moving spring 21. While adjusting the position of the cutting blade 6, the installation stability of the cutting blade 6 is also adjusted. The frame 2 is moved by the handle 22.
