Description

Technical Field

[0001] This utility model relates to the field of landscape architecture, specifically to a grass-pressing roller. Background Technology

[0002] In landscaping and golf courses, lawn rollers are commonly referred to as lawn rollers or lawn compactors. They are made of heavy metal or concrete cylinders and are rolled across the turf surface by hand or mechanical means to compact and level the grass, promote root growth, and create a smoother, more aesthetically pleasing lawn.

[0003] They come in various forms, categorized by usage scenarios and needs: there are manual rollers suitable for small lawns, pushed by the operator, lightweight, and suitable for home gardens or small green spaces; and tractor-tethered rollers suitable for large lawns. They can also be categorized by structure: there are solid rollers suitable for harder surfaces; and hollow rollers that can be filled with water to increase weight and adapt to different soil conditions.

[0004] Existing tractor-drawn lawn rollers typically have a fixed height, making it difficult to adjust flexibly according to actual grass conditions and operational needs. This results in a situation where, if the roller is too high, the pressure is insufficient, leading to poor compaction and smoothing; conversely, if the roller is too low, it will over-compact the grass, potentially damaging the turf. This lack of adjustability directly impacts the overall effectiveness of lawn compaction and the quality of lawn maintenance. Summary of the Invention

[0005] The purpose of this utility model is to provide a straw pressing roller that solves the problems mentioned in the background art.

[0025] The hydraulic cylinder 401 of the lifting assembly 4 is fixed to the arc frame 102 of the frame assembly 1 and the connecting shaft 301 of the roller assembly 3 via the first connecting seat 402 and the second connecting seat 403, respectively. When the hydraulic cylinder 401 extends or retracts, it uses the roller assembly 3 in contact with the ground as the fulcrum to pull or push the connecting shaft 301, thereby supporting or lowering the frame assembly 1. The frame assembly 1 drives the roller assembly 5 connected to the side bearing seat 502 to rise and fall synchronously through the support frame 101, so as to achieve precise adjustment of the height of the roller assembly 5.

[0026] The roller body 501 of the roller assembly 5 is fixed on the support frame 101 by the bearing seat 502. When the frame assembly 1 is pulled and moved, the roller body 501 contacts the lawn and rolls synchronously with the whole machine, using the weight of the roller to compact the lawn.

[0027] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
