Description

Technical Field

[0001] This utility model relates to the field of skid steer loader accessories technology, specifically a grooving device for skid steer loader accessories. Background Technology

[0002] A skid steer loader is a wheeled, specialized chassis-based machine that uses the difference in linear speed between the wheels on both sides to achieve vehicle steering. It employs a wheeled running gear, all-wheel drive, and skid steering, allowing for rapid and random changes or attachment of various work attachments on-site to adapt to different working environments and tasks.

[0003] Currently, grooving devices, as a type of skid chuck, are widely used in grooving rigid pavements to facilitate road repairs, drainage pipes, gas pipes, electrical conduits, and fiber optic cable conduits. However, existing grooving mechanisms are generally circular plate sawing structures. When grooving, they can only cut two strip slits in the pavement. Subsequently, a pickaxe is needed to break up the section between the two slits, making the entire grooving process cumbersome and inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a grooving device for skid steer loader accessories, in order to solve the problem that the current grooving device is cumbersome and inefficient when grooving the road surface.

[0006] Preferably, wheel frames are fixed on both sides of the bottom end of the connecting frame, and support wheels are rotatably installed at the bottom of the wheel frames. A support leg is hinged to the outer side wall of the housing near the bottom end, and a slip shoe is hinged to the bottom end of the support leg. A slot is fixed in the middle of the support leg. It also includes a support telescopic cylinder with the top end of the piston cylinder hinged to the outer side wall of the housing and located on the upper side of the support leg. The bottom end of the piston rod of the support telescopic cylinder is hinged to the slot.

[0007] Preferably, the skateboard includes a skateboard with its front end bent upwards and an ear seat fixed to the top surface of the skateboard and hinged to the bottom end of the support leg.

[0008] Preferably, a plurality of toothed supports are welded circumferentially to the outer peripheral wall of the wheel, and the pick-shaped cutting teeth are detachably fitted onto the toothed supports.

[0009] Preferably, the front wall of the connecting frame is fixedly connected with a pair of vertical plates, and guide rods are respectively sleeved between the top and bottom of the two pairs of vertical plates.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a slotting device for a skid steer loader auxiliary, wherein the rear end of a connecting frame 1 is hinged to the working end of the skid steer loader; wherein the working end of the skid steer loader includes a swing arm driven by a hydraulic cylinder to swing up and down, and the rear end of the connecting frame 1 is hinged to the front end of the swing arm. Wheel frames 1.3 are fixed to both sides of the bottom end of the connecting frame 1, and support wheels 1.4 are rotatably mounted on the bottom of the wheel frames 1.4. Vertical plates 1.1 are fixedly connected in pairs to the front wall of the connecting frame 1, and guide rods 1.2 are respectively sleeved between the top and bottom ends of the two paired vertical plates 1.1.

[0025] The grooving mechanism 3 includes a housing 3.1, a wheel 3.2 rotatably mounted inside the cavity of the housing 3.1, multiple pick-shaped cutting teeth 3.3 circumferentially fixed to the outer peripheral wall of the wheel 3.2, and a hydraulic motor 3.4 fixed to the outer side wall of the housing 3.1 for driving the wheel 3.2 to rotate. An ear plate 3.7 is fixed to the top of the housing 3.1. A guide sleeve 3.6 is fixed to the rear wall of the housing 3.1 and is slidably fitted with the guide rod 1.2.

[0026] A transverse telescopic cylinder 2 is connected between the front wall of the connecting frame 1 and the rear end of the housing 3.1. That is, the transverse telescopic cylinder 2 pushes the slotting mechanism 3 to move laterally under the guidance of the guide rod 1.2 and the guide sleeve 3.6.

[0027] The piston rod of the lifting telescopic cylinder 5 is hinged at the front end to the ear plate 3.7, and the piston cylinder of the lifting telescopic cylinder 5 is hinged at the rear end to the connecting seat 5.1, which is fixed to the top of the working end of the skid steer loader. That is, the telescopic movement of the lifting telescopic cylinder 5 can realize the up-and-down swing of the grooving mechanism 3 and the connecting frame 1 as a whole around the front end of the skid steer loader working arm, so as to adjust the digging depth.

[0028] The top of the support leg 4 is hinged to the outer wall of the housing 3.1 near the bottom. A sliding shoe 7 is hinged to the bottom of the support leg 4. A slot 4.1 is fixed in the middle of the support leg 4. It also includes a support telescopic cylinder 6, the top of which is hinged to the outer wall of the housing 3.1 and located above the support leg 4. The bottom end of the piston rod of the support telescopic cylinder 6 is hinged to the slot 4.1. The sliding shoe 7 includes a sliding plate 7.1 with its front end bent upwards and an ear seat 7.2 fixed to the top surface of the sliding plate 7.1 and hinged to the bottom of the support leg 4. The support telescopic cylinder 6 extends and retracts accordingly, allowing the sliding plate 7.1 and the support wheel 1.4 to support the slotting mechanism 3. The sliding plate 7.1 can be used for orientation calibration and guidance.

[0029] In summary, the skid steer loader serves as a mobile platform to facilitate the movement of the grooving structure 3 to the work site and to carry the grooving mechanism 3 along the grooving location to perform the grooving work.

[0030] During grooving, the skid steer loader's boom lowers, causing the support wheel 1.4 to rest on the road surface. The lifting telescopic cylinder 5 extends accordingly, causing the grooving mechanism 3 to lower as a whole until the pick-shaped cutting teeth 3.3 contact the road surface. Simultaneously, the support telescopic cylinder 6 extends and retracts accordingly, temporarily placing the sliding plate 7.1 on the road surface.

[0031] The hydraulic motor 3.4 adjusts the wheel 3.2 to rotate, which enables the pick-shaped cutting teeth 3.3 to break and excavate the road surface.

[0032] Several tooth holders 3.5 are welded circumferentially to the outer wall of the wheel 3.2, and pick-shaped cutting teeth 3.3 are detachably mounted on the tooth holders 3.5. That is, when a pick-shaped cutting tooth 3.3 is severely worn or damaged, it can be flexibly replaced.

[0033] The lateral telescopic cylinder 2, the lifting telescopic cylinder 5, and the support telescopic cylinder 6 are all hydraulic cylinders. The power for the hydraulic cylinders and the hydraulic motor 3.4 comes from the high-pressure hydraulic fluid supplied by the oil pump on the skid steer loader itself.
