Description

Technical Field

[0001] This utility model relates to the field of excavator technology, specifically to a quick conversion adapter for excavator buckets. Background Technology

[0002] An excavator, also known as a digger or excavator loader, is a heavy-duty construction machine used for digging, moving, and transporting soil and other materials. It typically consists of a chassis, a rotating platform, a boom system, and a working device. The excavator bucket is a working device used by the excavator, often for digging, transporting, and loading soil, rocks, and other materials. An excavator bucket adapter is an accessory for excavators, usually used to change different types of excavator buckets. However, existing excavator bucket adapters have poor flexibility, thus reducing the speed of changeover. Therefore, we propose a quick-change excavator bucket adapter. Utility Model Content

[0003] The purpose of this invention is to provide a quick-change adapter for excavator buckets to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick conversion connector for excavator buckets, comprising a bracket, a fixed hook fixedly connected to the right end of the bottom of the bracket, and a first reserved groove opened at the left end of the bottom of the bracket, a worm gear movably connected to the left end of the inner surface of the first reserved groove, and a movable hook fixedly connected to the middle end of the outer surface of the worm gear, and a worm movably connected to the left end of the inner surface of the bracket, and a hexagonal slot opened on the left side of the worm.

[0005] Preferably, the upper end of the inner surface of the bracket has two reserved holes, and the right end of the inner surface of the bracket has a through groove.

[0006] Preferably, a limiting disk is fixedly connected to the back of the worm gear, and the inner surface of the limiting disk is provided with a plurality of equally spaced limiting holes.

[0007] Preferably, the worm gear is meshed with the worm wheel, and a second reserved groove is provided on the back of the bracket at the corresponding position of the limiting plate.

[0008] Preferably, a screw hole is provided on the back of the bracket at the corresponding position of the second reserved slot, and a screw is threaded onto the inner surface of the screw hole.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This invention uses an external pin that passes through a pre-drilled hole to mount the bracket on the excavator boom. The fixed hook is connected to the bucket pin at the front end of the excavator bucket. By inserting an external hexagonal wrench into the hexagonal slot and rotating it, the worm gear can be rotated. With the cooperation of the worm wheel, the movable hook can be extended outward, thereby connecting the movable hook to the bucket pin at the rear end of the excavator bucket. After it is fixed, the screw can be passed through the corresponding limiting hole and screwed into the screw hole to fix the position of the movable hook. Attached Figure Description

[0015] 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.

[0016] The bracket 1, through groove 2, reserved hole 3, hexagonal slot 4, movable hook 5, fixed hook 6, limiting hole 7, second reserved groove 8, screw 9, limiting plate 10, first reserved groove 11, screw hole 12, worm gear 13 and worm 14 in this application are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. Example

[0017] Please see Figure 1 and Figure 3The following technical solution is provided, specifically disclosed: a bracket 1 is included, a fixed hook 6 is fixedly connected to the right end of the bottom of the bracket 1, and a first reserved groove 11 is opened at the left end of the bottom of the bracket 1. A worm gear 13 is movably connected to the left end of the inner surface of the first reserved groove 11, and a movable hook 5 is fixedly connected to the middle end of the outer surface of the worm gear 13. A worm 14 is movably connected to the left end of the inner surface of the bracket 1, and a hexagonal slot 4 is opened on the left side of the worm 14. By inserting an external hexagonal wrench into the hexagonal slot 4 and rotating it, the worm 14 can be driven to rotate, and with the cooperation of the worm gear 13, the movable hook 5 can be driven to expand outward, thereby connecting the movable hook 5 with the bucket pin at the rear end of the excavator bucket. Example
