Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

Referring to fig. 1-2, a bucket convenient for replacing shovel blades according to a preferred embodiment of the present invention includes a bucket body 1, the bucket body 1 is provided with a connecting seat at the back thereof, the connecting seat is used for connecting with a driving end of an excavator, a plurality of shovel blades 2 are provided at an end of an opening of the bucket body 1, the products 2 are generally parallel to the ground of the bucket body 1, and the end of the shovel blades 2 is pointed, so as to facilitate shoveling sand, soil, construction waste, and the like.

In the invention, the shovel blade 2 comprises a shovel blade inner core 21 fixedly connected with the bucket body 1 and a grinding sheet 22 sleeved outside the shovel blade inner core 21, the inner core 21 is provided with a strip-shaped groove at the end part thereof, the inner core is clamped on a connecting sheet of the bucket body 1 through the strip-shaped groove, meanwhile, the upper surface and the lower surface of the strip-shaped groove at the end part thereof are provided with first through holes, and the connecting sheet is provided with corresponding threaded holes.

There is abrasive disc 22 at the external connection of inner core 21, abrasive disc 22 itself is the slice of bending, specifically be lower abrasive disc 221 and last abrasive disc 222 including interconnect, the contained angle that appears the acute angle between lower abrasive disc 221 and last abrasive disc 222 between the two, tip between lower abrasive disc 221 and last abrasive disc 222 has all set up the second through-hole that corresponds first through-hole, inner core 21 and abrasive disc 22 are when specifically connected, with shovel piece inner core 21 through the recess block to the connecting piece on, then embolia shovel piece inner core 21 with abrasive disc 22 on, through seeing through the second through-hole with the screw, first through-hole screw in screw hole, realize fixed connection to both, inner core 21 has been realized, detachable connection of abrasive disc 22.

In order to ensure the connection stability of the shovel blade inner core 21 and the grinding sheet 22, prevent the grinding sheet 22 from shifting from the physical position of the shovel blade inner core 22 when receiving a lateral impact force, and process the connection surface between the shovel blade inner core and the grinding sheet 22 to increase the connection stability of the shovel blade inner core and the grinding sheet.

Specifically, referring to fig. 2, the upper/lower surfaces of the shovel blade inner core 21 are provided with semi-cylindrical first grooves, the inner surfaces of the lower blade 221/upper blade 222 are provided with corresponding semi-cylindrical clamping columns, and the radius of the semi-cylindrical clamping columns is slightly smaller than that of the first grooves, so that the shovel blade inner core 21 can be clamped into and connected to the first grooves through the semi-cylindrical clamping columns, thereby achieving tight connection between the shovel blade inner core and the first grooves, increasing the area of the connection surface between the shovel blade inner core and the first grooves, and preventing the shovel blade inner core from falling off or shifting even when receiving impact force laterally.

A gap is further arranged between the joint of the lower grinding sheet 221 and the upper grinding sheet 222, and the angle between the lower grinding sheet 221 and the upper grinding sheet 222 can be changed through external force through the gap, so that the grinding sheet 22 can be conveniently installed on the shovel blade inner core 21.

Because shovel piece inner core 21 and abrasive disc 22 have both been connected through first recess and card post, because large-scale mechanical equipment's processing technology is crude relatively, and both are difficult to accomplish the laminating completely after connecting, lead to both to laminate hardly totally, cause and fill through counting into the foamed adhesive, in follow-up change, only need burn the foamed adhesive, also can easily dismantle it.

The invention has at least the following advantages:

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, it should be noted that, for those skilled in the art, many modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
