Description

Technical Field

[0001] The utility model belongs to the field of municipal construction, and particularly relates to a groove leveling device. Background Art

[0002] When trenching, an excavator is generally used to dig out the prototype, and then the trench is cleared and leveled manually. To smooth the trench, workers need to use shovels to gradually clear the soil, and then use a wheelbarrow to transport the soil, which is labor-intensive. At present, there are also some leveling devices that use excavator buckets for leveling. The leveling device is fixed on the excavator bucket or directly made into a trench-shaped bucket for leveling. At present, most of the leveling devices using excavators have complex structures, and due to the different widths and inclinations of the trenches, the leveling device modified on the basis of the excavator bucket can only be applied to trenches of one shape, with low utilization rate and relatively wasteful resources. Summary of the invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the background technology and provide a groove leveling device.

[0004] The present invention is achieved through the following technical solutions:

[0005] A groove leveling device includes an excavator, a bottom plate is welded on the bottom surface of the front part of the bucket of the excavator, and a plurality of adjustment plates are symmetrically hinged on both sides of the bottom plate, and the outermost adjustment plates are hinged to a side plate, and the widths of the adjustment plates and the side plates are equal to the bottom plate; the upper surfaces of the bottom plate, the adjustment plate and the side plates are all provided with connecting plates, and the connecting plates are provided with screw holes, and the inner threads of the screw holes are connected to screw rods, and the screw rods span the hinges, and nuts are provided at both ends of the screw rods; threaded holes are provided on the front and rear side surfaces of the bottom plate, the adjustment plate and the side plates, and the bending between the bottom plate and the adjustment plate or the bending between the adjustment plates or the bending between the adjustment plates and the side plates can be fixed by connecting rods, and the two ends of the connecting rods are fixed by bolts passing through the threaded holes.

[0006] Preferably, the articulation is hinge articulation.

[0007] Preferably, the base plate width is 20-40 cm.

[0008] The groove leveling device of the present invention can greatly reduce the labor intensity of workers and improve construction efficiency. It can also be flexibly adjusted according to the bottom width and side slope inclination of the groove. The adjustment is simple and quick, and can be applied to grooves of different widths and inclinations, thereby improving the utilization rate of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0015] The groove leveling device of the present invention is an improvement on the existing excavator. The drawings of this embodiment only show the bucket 1 of the excavator, and do not show the entire excavator. The present invention adds a leveling device to the front of the bucket 1 of the excavator, and welds a horizontal bottom plate 2 on the bottom surface of the bucket 1. The bottom plate 2 is a rectangular plate, and the width of the bottom plate 2 is preferably 20-40cm. A number of adjustment plates 3 are symmetrically hinged on both sides of the bottom plate 2. The adjustment plates 3 are also rectangular plates. The width and thickness of the adjustment plates 3 are the same as those of the bottom plate 2. The adjustment plates 3 are used to adjust the width and inclination angle of the leveling device. The outermost adjustment plates 3 at the left and right ends are both hinged to a side plate 4, and the width and thickness of the side plate 4 are also equal to those of the bottom plate 2. At the hinge, the bottom plate 2 and the adjustment plate 3 can rotate relative to each other, the adjustment plates 3 can rotate relative to each other, and the adjustment plates 3 and the side plates 4 can rotate relative to each other. In this embodiment, the bottom plate 2 and the adjustment plate 3, the adjustment plates 3 and the adjustment plates 3, and the adjustment plates 3 and the side plates 4 are preferably hinged with hinges 11.

[0016] A connecting plate 5 is provided near the hinged part of the upper surface of the bottom plate 2, the adjusting plate 3 and the side plate 4. The connecting plate 5 is provided with a screw hole, and the screw hole is threadedly connected with a screw rod 6. The screw rod 6 spans the hinged part, that is, the screw rod 6 is perpendicular to the rotation axis of the hinge 11. Nuts 7 are provided at both ends of the screw rod 6, and the two ends of the screw rod 6 are fixed by nuts 7. The screw rod 6 can fix the bottom plate 2 and the adjusting plate 3, the adjusting plate 3 and the adjusting plate 3, and the adjusting plate 3 and the side plate 4 so that they can no longer rotate relative to each other, thereby fixing the adjusted width of the device.

[0017] Threaded holes 8 are provided on the front and rear sides of the bottom plate 2, the adjustment plate 3, and the side plate 4. Connecting rods 9 can be fixed between adjacent threaded holes 8. The bending part between the bottom plate 2 and the adjustment plate 3, or the bending part between the adjustment plate 3 and the adjustment plate 3, or the bending part between the adjustment plate 3 and the side plate 4 can be fixed by the connecting rods 9. Both ends of the connecting rod 9 are fixed by bolts 10 passing through the threaded holes 8. The connecting rod 9 is used to fix the tilt angle of the entire device.

[0018] During the use of the present invention, first, the width of the bottom surface of the device is adjusted according to the width of the groove, so that the total horizontal width of the bottom plate 2 and several adjustment plates 3 is equal to the width of the groove, and then the screw 6 is connected between the two connecting plates 5 at the hinge, and the nuts 7 are tightened at both ends of the screw 6 to fix it. At this time, the hinge can no longer rotate relative to each other, and the other adjustment plates 3 located at the edge of the groove are rotated upward to form a bending part, so that the inclination angle of the bending part formed by the adjustment plate 3 and the side plate 4 is consistent with the inclination angle of the groove side slope, and the bending part is upward along the groove side slope, and then the connecting rod 9 is fixed between the two adjacent bolt 10 holes at the bending part, and the two ends of the connecting rod 9 are fixed to the side of the bending part by bolts 10 passing through the bolt holes 8, thereby fixing the inclination angle of the entire device. When adjusting according to the width of the groove, the bend may be at the hinge of the bottom plate 2 and the adjusting plate 3, or at the hinge of the adjusting plate 3 and the adjusting plate 3, or at the hinge of the adjusting plate 3 and the side plate 4. The inclination angles on both sides are adjusted by rotating the bend. After adjusting the inclination angle of the side plate 4, the bend is fixed by the connecting rod 9 so that the bend can no longer rotate. In this way, a leveling device that matches the shape of the groove is adjusted. After the groove prototype is excavated, the device can be used to level the groove. During leveling, the device can clean and level the bottom and side slope of the groove at one time, and can directly transport the cleaned soil to the outside of the groove, which is much more efficient than manual leveling with a shovel.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
