DETAILED DESCRIPTION

[0019] The excavator bucket capable of quickly replacing bucket teeth of the present invention will be described below in conjunction with the accompanying drawings.

[0020] In the first embodiment of the present application, Figures 1 to 5As shown, the bucket capable of quickly replacing bucket teeth (hereinafter referred to as "this patent") comprises a bucket upper plate 1, a bucket side plate 1 2, a bucket side plate 2 3, a bottom plate 4, a bucket tooth base 5, an L-shaped bucket tooth locking hammer 5-1, a clamping head 5-11, a handle 5-12, a bucket tooth locking hammer working chamber 5-2, a locking hammer reset spring 5-3, a bucket tooth 6 and a control hole 7. The lower end of the bucket upper plate 1 is fixedly connected to the rear of the bottom plate 4, and the bucket side plate 1 2 and the bucket side plate 2 3 are welded and installed on both sides of the bucket upper plate 1 and the bottom plate 4, respectively. The bucket tooth base 5 is installed at equal intervals at the front end of the bottom plate 4, and control holes 7 are provided on the side of the bottom plate 4 to install four corner openings 4-1, and a gear chamber 4-3 is provided inside the bottom plate 4. The four corner openings 4-1 are connected in series with the gear 4-2 in the gear chamber 4-3 through a transmission shaft 4-6, and the lower part of the gear chamber 4-3 is connected to the control plate working chamber 4-4. One end of the control panel working chamber 4-4 is connected to the bucket tooth locking hammer working chamber 5-2, and the control panel 4-5 is slidably installed inside the control panel working chamber 4-4. The gear 4-2 meshes with the toothed belt on the control panel 4-5. The handle 5-12 of the L-shaped bucket tooth locking hammer 5-1 inside the bucket tooth locking hammer working chamber 5-2 is installed at a position close to and above the control panel working chamber 4-4 through a rotating shaft. The handle 5-12 is fixedly connected to the clamp 5-11, and a locking hammer reset spring 5-3 is provided above the clamp 5-11. The lower part of the clamp 5-11 extends out of the lower surface of the bucket tooth base 5, and the lower surface of the handle 5-12 has a slope. The end of the control panel 4-5 is aligned with the sloped side of the handle 5-12; the bucket tooth 6 is sleeved on the bucket tooth base 5, and a bucket tooth fixing groove 6-2 is provided in the bucket tooth installation groove 6-1 of the bucket tooth 6, and the lower half of the clamp 5-11 is clamped into the bucket tooth fixing groove 6-2.

[0021] The utility model number is CN218027936U, which is an excavation bucket tooth with a quick disassembly structure (hereinafter referred to as "the patent"). Each bucket tooth in the patent has an independent fixing mechanism. If all bucket teeth need to be replaced, the operation needs to be repeated many times, which is not very convenient to use. However, the patent uses a retractable L-shaped bucket tooth locking hammer 5-1 to fit into the bucket tooth fixing groove 6-2 of the bucket tooth 6 to fix the bucket tooth 6. At the same time, the transmission shaft 4-6 is used to realize the linkage control of the four-corner mouth 4-1 to multiple control panels 4-5 and the L-shaped bucket tooth locking hammer 5-1, so that multiple bucket tooth bases 5 can synchronously lock and release their respective bucket teeth 6, so that the staff only needs to loosen all bucket teeth 6 to replace the corresponding bucket teeth 6 or all bucket teeth 6.

[0022] The structure of the second embodiment is basically the same as that of the first embodiment, except that Figure 6As shown, there is a twenty-degree angle between the lower surface of the handle 5-12 and the chuck 5-11. This angle allows the handle 5-12 and the chuck 5-11 of the L-shaped bucket tooth locking hammer 5-1 to be on the forward path of the end of the control board 4-5 when the handle 5-12 and the chuck 5-11 are lowered, and the handle 5-12 can be smoothly lifted up when the control board 4-5 moves forward, thereby lifting the L-shaped bucket tooth locking hammer 5-1 with the rotating shaft as the center of the circle, thereby unlocking the bucket tooth 6.

[0023] In order to further optimize the working efficiency of the present application, in order to prevent mud and sand from entering the control hole 7 and to open the plug of the control hole 7 in time when necessary, the control hole 7 is provided with an iron plug, and an inclined pry hole is provided on the side of the plug. In order to facilitate the installation of the bucket tooth 6, the lower surface of the clamping head 5-11 facing the end of the bucket tooth base 5 is provided with a gentle slope. The bucket tooth 6 only needs to be sleeved on the bucket tooth base 5 and knocked into place with a hammer, and the clamping head 5-11 can be lifted up and automatically stuck into the bucket tooth fixing groove 6-2. In order to increase the service life of the bucket tooth 6, the bucket tooth 6 is made of high manganese steel.

[0024] When in use, the bucket with bucket teeth that can be quickly replaced can be installed and the equipment can be put into use.

[0025] When the utility model is in use, the specific operations are as follows:

[0026] During installation, it is only necessary to sleeve the bucket tooth 6 onto the bucket tooth base 5 and knock it into place with a hammer, and the clamping head 5-11 can be lifted up and automatically clamped into the bucket tooth fixing groove 6-2 under the action of the locking hammer reset spring 5-3.

[0027] When replacement is required, first control the bucket to lift and let the bucket tooth 6 face vertically upward, remove the plug in the control hole 7, insert the tool into the four-corner port 4-1 in the control hole 7, rotate the four-corner port 4-1 clockwise, and the four-corner port 4-1 drives all the gears 4-2 through the transmission shaft 4-6. The gear 4-2 drives the control board 4-5 forward through the toothed belt. When the control board 4-5 moves forward, the handle 5-12 can be smoothly lifted, and then the L-shaped bucket tooth locking hammer 5-1 is lifted with the shaft as the center of the circle, so that the clamping head 5-11 is disengaged from the bucket tooth fixing groove 6-2, and the bucket tooth 6 is disengaged. At this time, all the bucket teeth 6 can be replaced as needed, or only the damaged bucket teeth 6 can be replaced, and then the four-corner port 4-1 is rotated counterclockwise to reset the control board 4-5. After the L-shaped bucket tooth locking hammer 5-1 is disengaged from the control board 4-5, it can be reset under the action of the locking hammer reset spring 5-3 and the bucket tooth 6 is clamped again.

[0028] In summary, the bucket of the utility model embodiment capable of quickly replacing bucket teeth, controls the L-shaped bucket tooth locking hammer 5-1 through the four corner openings 4-1 and the control panel 4-5 to lock the bucket teeth 6 on the bucket tooth base 5. When the bucket teeth 6 need to be replaced, it is only necessary to control the L-shaped bucket tooth locking hammer 5-1 to lift up through the four corner openings 4-1 and the control panel 4-5 to unlock the bucket teeth 6 on the bucket tooth base 5. Then, the bucket teeth 6 can be replaced by simply putting them on the bucket tooth base 5, thereby realizing a very simple and labor-saving replacement of the bucket teeth, which can effectively improve the maintenance efficiency and reduce the difficulty of maintenance.

[0029] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
