[0002] Loaders are earthwork construction machines widely used in construction projects such as roads, railways, buildings, hydropower, ports, and mines. They are mainly used to shovel and load bulk materials such as soil, sand, lime, and coal, and can also do light digging of ore and hard soil. The bucket is an important part of the loader, and is mainly used to shovel and deliver materials during loader operation. Usually, the teeth on the bucket are in direct contact with the materials, and the bucket relies on the teeth to dig bulk materials. Therefore, the wear resistance and service life of the teeth are crucial to the performance of the bucket. The teeth are generally fixedly connected to the bucket. If the teeth are severely worn, the entire bucket needs to be replaced, which is costly. Summary of the invention

[0003] In order to reduce the cost of replacing shovel teeth, the present application provides a loader bucket.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] The present application embodiment discloses a loader bucket. Figure 1 and Figure 2 The loader bucket includes a bucket body 1, shovel teeth 2 detachably connected to the opening of the bucket body 1 for digging bulk materials, and a connecting component 3 arranged in the bucket body 1 for connecting the shovel teeth 2. The bucket body 1 includes a bucket shell 11 and bucket walls 12 fixedly connected to both sides of the bucket shell 11. A slot for installing the connecting component 3 is provided on one side of the opening end of the bucket shell 11 close to the ground.

[0030] When the staff operates the loader to shovel or dig bulk materials, the bucket body 1 shovels or digs ore and hard soil through the shovel teeth 2; when the bucket body 1 has been used for a period of time and the shovel teeth 2 are severely worn and need to be replaced, the staff moves the connecting component 3 from the slot to the outside, the staff removes the severely worn shovel teeth 2 from the connecting component 3 and installs new shovel teeth 2. After the installation is completed, the connecting component 3 is installed back into the slot to complete the replacement of the shovel teeth 2.

[0031] The connection assembly 3 includes a mounting block 31 slidably connected in the card slot, the mounting block 31 is located between the two bucket walls 12, and the shovel tooth 2 is detachably connected to the mounting block 31. Specifically, a first slider 21 is fixedly connected to one side of the shovel tooth 2, and a first slide groove 311 for the first slider 21 to slide is provided on one side of the mounting block 31. Both the first slider 21 and the first slide groove 311 are T-shaped. When the mounting block 31 is removed from the two bucket walls 12, the detachable connection between the shovel tooth 2 and the connection assembly 3 can be achieved through the sliding cooperation of the first slider 21 and the first slide groove 311.

[0032] During use, the staff moves the mounting block 31 out from between the two bucket walls 12, slides the shovel tooth 2 off the mounting block 31, and replaces the new shovel tooth 2 onto the mounting block 31 through the sliding cooperation of the first slider 21 and the first slide groove 311. After the replacement is completed, the mounting block 31 is installed back into the slot to complete the replacement of the shovel tooth 2.

[0033] Fixing devices 4 for fixing the connection assembly 3 in the slot are provided inside the two bucket walls 12 , and a mounting groove 121 for mounting the fixing device 4 is provided on one side of the bucket wall 12 facing the shovel teeth 2 .

[0034] The fixing device 4 includes a fixing part fixedly connected to the bottom of the mounting groove 121, and connecting shafts 32 are fixedly connected at both ends of the mounting block 31. The fixing part is connected to the end of the connecting shaft 32. The fixing part includes an electric push rod 41 and a battery 411, so that when the staff needs to replace the shovel tooth 2, the mounting block 31 can be pushed out of the slot to the outside by operating the electric push rod 41, so that the shovel tooth 2 slidingly connected to the mounting block 31 can be replaced.

[0035] Reference Figure 2 and Figure 3 In order to reduce the number of times the shovel teeth 2 are replaced, two rows of shovel teeth 2 are provided, and the two rows of shovel teeth 2 are detachably connected to the opposite sides of the mounting block 31, that is, a second slide groove for the first slider 21 to slide is also provided on the other side opposite to the first slide groove 311 on the mounting block 31. It can be understood that the second slide groove is also T-shaped.

[0036] Under normal circumstances, the staff installs the shovel teeth 2 in both the first slide groove 311 and the second slide groove. After the bucket body 1 has been used for a period of time, if the shovel teeth 2 on one side are severely worn during construction, the staff operates the electric push rod 41 to move the mounting block 31 out of the bucket body 1. The staff rotates the mounting block 31 180 degrees to expose the shovel teeth 2 set in the second slide groove, and then operates the electric push rod 41 to move the mounting block 31 back between the two bucket walls 12. At this time, the shovel teeth 2 slidingly connected to the first slide groove 311 are embedded in the slot, and the update of the shovel teeth 2 is completed to avoid delays in the progress of the project.

[0037] Reference Figure 2 and Figure 3 In order to realize automatic rotation of the mounting block 31, the fixing device 4 also includes a connecting plate 42 fixedly connected to one end of the push rod of the electric push rod 41 and a rotating motor 43 detachably connected to the connecting plate 42 on the side away from the electric push rod 41. The output shaft of the rotating motor 43 is fixedly connected to the connecting shaft 32. An encoder is fixedly connected to the output shaft of the rotating motor 43. The encoder and the electric push rod 41 are both connected to the PLC controller. When the staff starts the rotating motor 43, when the encoder detects that the rotation amount of the output shaft of the rotating motor 43 is 180 degrees, the PLC controller controls the rotating motor 43 to stop.

[0038] When in use, the staff extends the push rods of the two electric push rods 41 by operating the PLC controller. Driven by the push rods of the two electric push rods 41, the connecting plate 42 moves to the side away from the bottom of the installation slot 121, so that the output shaft of the rotating motor 43 slides along the moving slot 44 to move the mounting block 31 out from between the two bucket walls 12. When the staff wants to replace the shovel tooth 2, after the mounting block 31 is moved out from between the two bucket walls 12, the staff operates the rotating motor 43 through the PLC controller to start. When the encoder collects the rotation amount of the output shaft of the rotating motor 43, the mounting block 31 is rotated 180 degrees around the connecting shaft 32, and then the push rod of the electric push rod 41 is controlled to retract until the shovel tooth 2 abuts against the slot, and the push rod of the electric push rod 41 stops moving, completing the replacement of the shovel tooth 2.

[0039] Reference Figure 3 In order to provide power to the electric push rod 41, a push door 13 is provided on the side of the bucket wall 12 away from the mounting block 31, and a placement groove for placing the battery 411 is opened at the corresponding position of the bucket wall 12. One side of the push door 13 is hinged on the bucket wall 12, and a mounting column 131 is fixedly connected to the side of the push door 13 away from the mounting block 31. A spring pin 14 for closing the push door 13 is provided on the side of the bucket wall 12 away from the mounting block 31, and a socket for inserting the spring pin 14 plug is opened on the mounting column 131. When the plug of the spring pin 14 is inserted into the socket, the free end of the push door 13 cannot rotate freely around its hinge axis, thereby realizing the closure of the placement groove.

[0040] The implementation principle of a loader bucket body 1 and a loader in the embodiment of the present application is as follows: after being used for a period of time, when it is found that the shovel teeth 2 are severely worn and affect the construction during the construction process, the staff controls the electric push rod 41 to move the mounting block 31 out from between the two bucket walls 12, and the staff controls the rotating motor 43 through the PLC control to make the mounting block 31 rotate along with the output shaft of the rotating motor 43. When the encoder fixedly connected to the output shaft of the rotating motor 43 collects the rotation amount of the output shaft of the rotating motor 43 reaching 180 degrees, the PLC controller controls the rotating motor 43 to stop, so as to rotate the shovel teeth 2 located on the second slide groove to the side away from the card groove, and then operates the push rod of the electric push rod 41 to retract through the PLC controller. By moving the lower mounting block 31 to its original position, the shovel tooth 2 can be replaced in time; when the construction is completed, the staff operates the electric push rod 41 through the PLC controller to move the mounting block 31 out from between the two bucket walls 12, and slides the severely worn shovel tooth 2 out of the mounting block 31 along the first slide groove 311 or the second slide groove, and slides the new shovel tooth 2 into the first slide groove 311 or the second slide groove corresponding to the replaced lower shovel tooth 2. After completing the replacement of the shovel tooth 2, the staff operates the electric push rod 41 through the PLC controller to reinstall the mounting block 31 back to its original position; when the power of the electric push rod 41 is insufficient, the staff opens the free end of the push door 13 by operating the spring pin 14, thereby replacing the battery 411 in the placement slot, thereby providing sufficient power to the electric push rod 41.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
