Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically to a skid steer loader cutting device with depth adjustment function. Background Technology

[0002] Existing disc trenchers are mainly used for trenching and grooving operations on hard and solid road surfaces such as cement roads, concrete roads, asphalt roads, highways, and expressways. Most trenching equipment on the market currently uses a tractor connected to a simple circular saw for trenching, which has several drawbacks. First, its work efficiency is low, making it difficult to meet the needs of large-scale construction. Second, during trenching, the discharged material tends to accumulate in the trench or cannot be effectively cleaned up, especially when trenching deep areas, where manual cleaning is extremely difficult, resulting in low efficiency, increased construction costs, and significant inconvenience and wasted time for subsequent work. Furthermore, traditional trenchers struggle to precisely control the cutting depth on uneven surfaces, leading to uneven trench depths and affecting construction quality. Therefore, there is an urgent need for a new cutting device that can improve work efficiency, effectively clean up excess material, and adapt to different road conditions. Utility Model Content

[0031] Furthermore, the cutting disc support 2 is provided with vertical slide rails 16 on both sides, and the depth adjustment plate assembly 6 is provided with a vertical slide groove 17 adapted to the vertical slide rails 16; the vertical slide groove 17 is installed on the vertical slide rails 16, and a limiting plate 25 is provided on the outer side.

[0033] Furthermore, it also includes a hydraulic control system for controlling the movement of the side-shift cylinder 3 and the depth adjustment cylinder 7, the hydraulic control system being connected to the hydraulic system of the skid steer loader.

[0034] Working principle of this utility model:

[0035] When using the skid steer loader cutting device with depth adjustment function of this utility model, first connect the rear attachment 1 to the skid steer loader to ensure that the connection is firm and reliable.

[0036] According to the construction requirements, by controlling the extension and retraction of the side-shifting cylinder 3, the position of the cutting disc support 2 in the horizontal direction is adjusted so that the cutting disc 4 is in a suitable transverse cutting position.

[0037] Then, according to the required cutting depth, the depth adjustment cylinders 7 on both sides are controlled separately. The cutting depth is the distance between the lowest point of the cutting disc 4's rotation diameter and the lower end face of the depth adjustment plate assembly 6 in contact with the road surface. When the cutting depth needs to be reduced, the depth adjustment cylinder 7 extends, pushing the depth adjustment plate assembly 6 downward along the vertical slide rail 16 on the cutting disc support 2, thereby reducing the cutting depth; conversely, when the cutting depth needs to be increased, the depth adjustment cylinder 7 shortens, and the depth adjustment plate assembly 6 moves upward, thereby increasing the cutting depth. In this process, since the depth adjustment cylinders 7 on the left and right sides can be adjusted independently, they can adapt well to uneven road surfaces, ensuring consistency in cutting depth.

[0038] The hydraulic motor 5 is started, driving the cutting disc 4 to rotate at high speed, initiating the cutting operation on the road surface. During the cutting process, the ditch-clearing component cylinder 31 extends and retracts as needed. When the ditch-clearing component cylinder 31 extends, it pulls the wire rope 33. Guided by the wire wheel 32, the wire rope 33 drives the cleaning hook component 34 to move upward in an arc along the guide wheel 36, clearing the cut sand, gravel, mud, and other materials out of the ditch. When the ditch-clearing component cylinder 31 retracts, the cleaning hook component 34 moves downward in an arc along the guide wheel 36 under the action of gravity, returning to its initial position, ready for the next cleaning operation.

[0039] Throughout the operation, the various components on the cutting disc support 2 work together to ensure the stable and efficient operation of the cutting device. After cutting is completed, first stop the operation of the hydraulic motor 5 and the trenching component cylinder 31, and then, as needed, remove the cutting device from the skid steer loader for maintenance and upkeep in preparation for the next use.

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
