Description

Technical Field

[0001] The utility model belongs to a construction tool, in particular to a slope brushing and leveling device for an excavator. Background Art

[0002] When leveling the site, constructing roads or excavating foundation pits, it is necessary to use manual or mechanical methods to level the inclined surfaces of the site, roads, large foundation pits and other slopes to facilitate subsequent protective construction operations. In order to control costs during construction, single or multiple excavators are often used, with one machine for multiple purposes, and the excavator bucket is used for leveling and slope brushing operations. Due to the limitations of the excavator bucket function, the excavator can only construct from the top of the slope to the bottom of the slope or from the bottom of the slope to the top of the slope, and then the excavator moves horizontally along the slope to construct the slope.

[0003] However, during the operation of the excavator, the bucket teeth will leave multiple tooth grooves on the working surface. In order to control the flatness of the overall working surface and facilitate the construction of subsequent projects, secondary leveling construction is required. Secondly, the bucket size is small and the single operation range is limited. When the working surface is large, the mechanical arm needs to operate repeatedly, the mechanical fuel consumption is large, and the construction efficiency is extremely low. Utility Model Content

[0026] The present invention will be further described below in conjunction with specific embodiments and drawings.

[0027] refer to Figure 1 to Figure 4 As shown, a slope brushing and leveling device for an excavator comprises a leveling rod 1, an adapter 2 and a boom pin 3.

[0028] The leveling rod 1 is a component that directly acts on the surface of the slope. A straight action edge 101 is provided at the lower part of the leveling rod 1. The straight action edge 101 pushes and scrapes the slope to achieve the final leveling of the site.

[0029] The adapter 2 is used for the transition connection between the leveling rod 1 and the excavator boom. The upper part of the leveling rod 1 is detachably connected to the adapter 2. The adapter 2 is provided with a boom pin 3 detachably connected to the excavator boom. The detachable connection at each connection point facilitates on-site disassembly and assembly, and is also convenient for replacing leveling rods 1 or adapters 2 of different specifications.

[0030] The leveling rod 1 is a straight rod-shaped structure, which is conducive to directly using the structure of the leveling rod 1 to form the working edge 101. Preferably, the leveling rod 1 is an H-shaped steel, and the flanges on both sides of the lower wing plate of the H-shaped steel are both working edges 101, so that the excavator can perform leveling operations both forehand and backhand.

[0031] A connecting end face 102 is provided on the upper portion of the leveling rod 1. The upper end face of the upper wing plate of the H-shaped steel is the connecting end face 102. The connecting end face 102 is fitted and connected to the lower end face of the adapter 2 to ensure a stable connection between the two.

[0032] The adapter seat 2 is a structure of steel plates welded together, including a seat bottom plate 201 and a seat side plate 202. The seat bottom plate 201 is detachably connected to the leveling rod 1, and bolt holes are provided on the upper wing plate of the leveling rod 1. Bolt holes are drilled according to the positions of the connecting bolts of the adapter seat. The four sides of the seat bottom plate 201 are connected to the leveling rod 1 through connecting bolts 203, with high connection strength and flexible disassembly and assembly in the later stage.

[0033] Two left and right seat side plates 202 are vertically welded and fixed on the seat bottom plate 201, and a boom pin shaft 3 is arranged between the two seat side plates 202. That is, the seat side plates 202 are used to realize the placement of the boom pin shaft 3, and the boom pin shaft 3 passes through the excavator boom and the seat side plates to realize the connection, with high connection strength and flexible disassembly and assembly in the later stage.

[0034] The boom pin 3 includes a first pin 301 and a second pin 302. Two types of pin holes are provided on most excavator booms. With the commonly used flip bucket, the two pins can adapt to most excavator booms to ensure the connection of the leveling rod 1 on the excavator boom.

[0035] The seat side plate 202 is an irregular plate, the first pin shaft 301 is located on the front side of the seat side plate 202 of the adapter seat 2, and the second pin shaft 302 is located on the rear side of the seat side plate 202 of the adapter seat 2. The first pin shaft 301 is higher than the second pin shaft 302. The position relationship of the pin shaft is also to adapt to the opening position of the pin hole on the current excavator boom.

[0036] The workflow of this utility model:

[0037] H-shaped steel adopts national standard finished products. The appropriate length can be selected according to the size of the working surface. It is generally more suitable to be the same width as the excavator. The adapter is made according to the specifications of the excavator boom connector and connected to the excavator boom through a pin. The adapter and H-shaped steel are connected by bolts. H-shaped steel, adapter, bolts and pins must be processed in the factory, and each component must be transported separately to the site for assembly to ensure that the adapter corresponds to the boom connector and H-shaped steel specifications and dimensions, and each component is firmly installed and does not loosen during use to avoid affecting the flatness of the working surface.

[0038] First, connect the adapter to the H-shaped steel with bolts, and then connect the adapter to the excavator arm with a pin shaft, and then you can start the slope leveling operation.
