Description

TECHNICAL FIELD

[0001] The utility model relates to roadbed side slope maintenance and finishing technical field, especially a roadbed side slope finishing device. BACKGROUND

[0002] When the roadbed side slope is finished, the earthwork of the widened part of the roadbed needs to be removed and the side slope of the road shoulder needs to be finished, and it needs to be compacted, the cross slope needs to be moderate, and the edge needs to be straight and smooth. Nowadays, excavators are often used to scrape and flatten the surface. However, because the excavator has digging teeth, the finished side slope has a concave-convex texture. To solve this problem, the patent document CN217399773U discloses a side slope finishing device for highway construction, which is essentially convenient to disassemble and replace the bucket teeth, thereby realizing the characteristics of stable use and easy assembly and disassembly of the bucket teeth. However, the modification of the excavator itself not only cannot achieve the claimed purpose, but also may cause the risk of unstable structure and easy falling of the digging teeth.

[0003] In the prior art, there are also patent documents CN201704721U and CN211596870U, which disclose a front-end scraping plate for a shovel of an excavator and a shovel, respectively. The front-end scraping plate is formed by a flat surface at the front end of the shovel, which can realize the purpose of one-time flattening of the side slope. However, in fact, the spacing between the digging teeth of each shovel is not fixed, and obviously such a structure cannot adapt to excavators with different tooth spacing, and the adaptability is poor.

[0004] The present application provides a roadbed side slope finishing device, which can quickly install and adapt to excavators of different specifications by installing and fixing a flat plate at the digging teeth, thereby achieving strong adaptability. UTILITY MODEL CONTENTS

[0005] In view of the above problems, the utility model provides a roadbed side slope finishing device to overcome the defects of the prior art and effectively solve the problems of the prior art that the side slope flattening device is not suitable for the existing excavator, cannot be quickly disassembled and replaced, and cannot adapt to excavators of different sizes.

[0006] The technical solution is to provide a roadbed side slope finishing device, which includes a flat plate, a horizontal groove on the flat plate, a plurality of clamping units in the horizontal groove, a horizontal double-headed screw in the clamping unit, a nut screwed on each end of the double-headed screw, a vertical rod fixed on the upper side of each nut and arranged in the front-rear direction, a hook hinged to the upper side of the vertical rod, and a flat plate fixed on the upper side of the hook. When the hook on the clamping unit hooks the digging teeth on the excavator, the double-headed screw is screwed, the vertical rods are moved closer to each other through the nuts, but the upper end of the hook is limited by the digging teeth at this time, the lower sides of the two hooks are moved closer to each other, and the flat plate is pressed and fixed on the excavator by the vertical rods.

[0007] Further, the longitudinal rod is sleeved with a cylinder, and a platform is arranged at the upper end of the cylinder.

[0008] Further, a rubber pad is pasted on the upper end surface of the platform.

[0009] Further, a rubber pad layer is pasted on the inner side of the upper end of the hook.

[0010] The utility model discloses a clever structure, through installing and fixing flat plate at the digging tooth, make the excavator can one time flatten the side slope, when needing to flatten the side slope, can install fast, can adapt to different specifications of excavator, and the adaptability is strong.

[0018] The specific implementation of the utility model is further explained in detail in combination with the drawings.

[0019] By Figures 1 to 7 The utility model discloses a clever structure, through installing and fixing flat plate at the digging tooth, make the excavator can one time flatten the side slope, when needing to flatten the side slope, can install fast, can adapt to different specifications of excavator, and the adaptability is strong.

[0020] In order to fix the plate 1 to the lower side of the bucket by the longitudinal rod 5, a cylinder 7 is fitted on the longitudinal rod 5, and a platform 8 is provided at the upper end of the cylinder 7.

[0021] To prevent the flat plate 1 from shaking during use, a shock-absorbing rubber pad is attached to the upper surface of the platform 8.

[0022] In order to ensure that the upper end of the hook 6 can be firmly attached to the digging teeth and prevent slippage, a rubber pad is attached to the inner side of the upper end of the hook 6.

[0023] It is worth noting that the longitudinal rod 5 and the cylinder 7 can be installed using bearings, or the cylinder 7 can be directly fitted onto the longitudinal rod 5.

[0024] When it is necessary to level the slope, as shown in the figure, multiple clamping units are arranged according to... Figure 1 The plate is positioned in the transverse groove 2 on the flat plate 1, and the upper end of the hook 6 is hooked onto the digging teeth of the bucket. Then, the double-ended screw 3 is turned, which moves the nuts 4 on both sides closer together. The lower sides of the hook 6 also move closer together. At the same time, the upper end of the hook 6 remains hooked onto the digging teeth. In this way, the longitudinal rod 5 moves upward and gradually clamps the flat plate 1. Multiple clamping units work simultaneously to fix the flat plate 1 to the underside of the bucket.

[0025] This utility model has an ingenious structure. By installing and fixing the plate 1 at the digging teeth, the digging bucket can level the slope in one go. When it is necessary to level the slope, it can be installed quickly and can adapt to digging buckets of different specifications, showing strong adaptability.
