[0038] The following will be combined with Figures 1 to 7 A bucket assembly and a working machine provided by an embodiment of the present invention are described. It should be understood that the following is only a schematic embodiment of the present invention and does not constitute any special limitation to the present invention.

[0039] An embodiment of the first aspect of the present invention provides a hydraulic control system, such as Figures 1 to 4As shown in the figure, the bucket assembly includes a bucket body, a bucket tooth 100, and a locking device 200.

[0040] Among them, a tooth seat 300 is arranged on the bucket body. An insertion hole 101 is arranged on the bucket tooth 100. The bucket tooth 100 is inserted onto the tooth seat 300 through the insertion hole 101. The locking device 200 is installed between the tooth seat 300 and the bucket tooth 100. The locking device 200 can be switched between a pressed locking position and a lifted unlocking position. In the state of the pressed locking position, the bucket tooth 100 is locked to the tooth seat 300; in the state of the lifted unlocking position, the bucket tooth 100 can be separated from the tooth seat 300.

[0041] In the bucket assembly provided by the present invention, a plurality of tooth seats 300 are arranged on the bucket body at intervals. A bucket tooth 100 is correspondingly installed on each tooth seat 300. Specifically, an insertion hole 101 adapted to the tooth seat 300 is arranged on the bucket tooth 100. The bucket tooth 100 can be inserted onto the tooth seat 300 through the insertion hole 101. A locking device 200 is installed between the tooth seat 300 and the bucket tooth 100. Manually pressing or lifting the locking device 200 can make it switch between the pressed locking position and the lifted unlocking position. As Figure 1 and Figure 2 shown, in the state of the pressed locking position, the locking device 200 locks the bucket tooth 100 on the tooth seat 300, and the bucket tooth 100 cannot be separated from the tooth seat 300. As Figure 3 and Figure 4 shown, in the state of the lifted unlocking position, the locking device 200 cannot lock and connect the bucket tooth 100 and the tooth seat 300. By pulling the bucket tooth 100 along the side away from the tooth seat 300, the bucket tooth 100 can be separated from the tooth seat 300.

[0042] During the process of replacing the bucket tooth 100, first lift the locking device 200 to make it switch to the lifted unlocking position; then take out the locking device 200, and then pull the bucket tooth 100 along the side away from the tooth seat 300 to separate the bucket tooth 100 from the tooth seat 300. Subsequently, insert the new bucket tooth 100 onto the tooth seat 300, then install the locking device 200 between the tooth seat 300 and the bucket tooth 100, and then press the locking device 200 to make it switch to the pressed locking position. At this time, the new bucket tooth 100 is locked to the tooth seat 300.

[0043] With this structural arrangement, the bucket tooth 100 is inserted onto the tooth seat 300 through the insertion hole 101, and the locking device 200 is installed between the bucket tooth 100 and the tooth seat 300. During the process of replacing the bucket tooth 100, manually press or lift the locking device 200 to make it switch between the pressed locking position and the lifted unlocking position, thereby realizing the disassembly and installation of the bucket tooth 100. Its operation process is labor-saving and there is no safety threat to the staff.

[0044] In an embodiment of the present invention, a first mounting hole 102 is provided on the bucket tooth 100. A second mounting hole 301 is provided on the tooth seat 300. The first mounting hole 102 and the second mounting hole 301 together form a locking mounting area. The locking device 200 is mounted into the locking mounting area. A first locking groove 103 is provided in the first mounting hole 102. The second mounting hole 301 includes a limiting side wall 302. The first locking groove 103 and the limiting side wall 302 are oppositely arranged along the insertion direction of the bucket tooth 100.

[0045] In the state of pressing the locking position, both ends of the locking device 200 are respectively limited and clamped in the first locking groove 103 and the limiting side wall 302 to prevent the bucket tooth 100 and the tooth seat 300 from separating from each other;

[0046] In the state of pulling up the unlocking position, both ends of the locking device 200 can be separated from the first locking groove 103 and the limiting side wall 302 respectively, so that the bucket tooth 100 can be separated from the tooth seat 300.

[0047] For example, as Figure 2 and Figure 4 shown, the first mounting hole 102 on the bucket tooth 100 penetrates through the side wall of the bucket tooth 100. Or rather, the first mounting hole 102 on the bucket tooth 100 communicates with the outside of the bucket tooth 100 and the inner cavity of the insertion hole 101. The first mounting hole 102 communicates with the second mounting hole 301 on the tooth seat 300 and together with the second mounting hole 301 forms a locking mounting area. The locking device 200 is mounted into the locking mounting area from the outer opening of the first mounting hole 102.

[0048] A first locking groove 103 is provided on the side wall of the first mounting hole 102, and one side wall of the second mounting hole 301 is the limiting side wall 302. The bucket tooth 100 is inserted onto the tooth seat 300 through the insertion hole 101, and it can only move in the insertion direction of the bucket tooth 100. Thus, by arranging the first locking groove 103 and the limiting side wall 302 oppositely along the insertion direction of the bucket tooth 100, a limiting effect can be formed on the bucket tooth 100 in the insertion direction.

[0049] Specifically, as Figure 2 shown, press down the locking device 200 to switch it to the pressing locking position. At this time, one end of the locking device 200 abuts against the first locking groove 103 of the bucket tooth 100, and the other end of the locking device 200 abuts against the limiting side wall 302 of the tooth seat 300. Thus, the bucket tooth 100 cannot move in the insertion direction. That is to say, the bucket tooth 100 and the tooth seat 300 are locked and connected.

[0050] As Figure 4As shown, the locking device 200 is lifted upward to switch it to the lifting unlocking position. At this time, one end of the locking device 200 is flipped to the outside of the bucket tooth 100, and accordingly, the end of the locking device 200 is separated from the first locking groove 103. At this time, the locking device 200 can be moved in the locking area to a position where the other end of the locking device 200 is separated from the limiting side wall 302. Subsequently, the locking device 200 is taken out of the locking installation area. Pulling the bucket tooth 100 to the side away from the tooth holder 300 can separate the bucket tooth 100 from the tooth holder 300.

[0051] In one embodiment of the present invention, the locking device 200 includes a bracket 210, a rotating connection member 220, and a manual adjustment portion 230. The manual adjustment portion 230 is rotatably connected to the bracket 210 through the rotating connection member 220. The manual adjustment portion 230 can rotate relative to the bracket 210 to switch between a push-lock position and a pull-unlock position.

[0052] When pressed to the locking position, the manual adjustment part 230 is rotated and clamped in the first locking groove 103, and the bracket 210 can be clamped in the limiting side wall 302; when pulled to the unlocking position, the manual adjustment part 230 is rotated to a position separated from the first locking groove 103, and the bracket 210 can be moved to a position separated from the limiting side wall 302.

[0053] Further, in one embodiment of the present invention, the edge of one side of the first mounting hole 102 close to the limiting side wall 302 extends to the inner side of the corresponding edge of the second mounting hole 301, so that the limiting side wall 302 and the bucket tooth 100 jointly form a second locking groove 303. The second locking groove 303 is used to clamp the bracket 210 to prevent the locking device 200 from leaving the locking installation area.

[0054] Specifically, if Figure 2 , Figures 4 to 7 As shown, the manual adjustment part 230 is rotatably connected to the bracket 210 through the rotating connecting member 220. For example, the rotating connecting member 220 is a pin. In this embodiment, the first mounting hole 102 and the second mounting hole 301 are both square holes. In the insertion direction of the bucket tooth 100, a first locking groove 103 is provided on a side wall of the first mounting hole 102, and the side wall is aligned with the corresponding side wall of the second mounting hole 301. The other side wall of the first mounting hole 102 is located on the inner side of the corresponding side wall of the second mounting hole 301, or in other words, the other side wall of the first mounting hole 102 protrudes to the inner side of the corresponding side wall of the second mounting hole 301, that is, the limiting side wall 302. As a result, the second locking groove 303 is formed between the bottom of the bucket tooth 100, the limiting side wall 302 and the bottom of the second mounting hole 301.

[0055] When installing the locking device 200, place the locking device 200 in the locking installation area through the outer opening of the first installation hole 102. When it is necessary to convert the locking device 200 to the pressing locking position, first move the bracket 210 to a position where one end of it is clamped in the second locking groove 303, and then press down the manual adjustment part 230 so that the manual adjustment part 230 is limited and clamped in the first locking groove 103. Thus, the locking device 200 locks and connects the bucket tooth 100 to the tooth seat 300. When it is necessary to convert the locking device 200 to the lifting unlocking position, first lift the manual adjustment part 230 upward so that the manual adjustment part 230 moves to the outside of the bucket tooth 100 and then separates from the first locking groove 103. Then move the bracket 210 to the side away from the second locking groove 303 until the bracket 210 completely disengages from the second locking groove 303. Subsequently, take out the locking device 200 and pull the bucket tooth 100 to the side away from the tooth seat 300.

[0056] In an embodiment of the present invention, the bracket 210 includes a connecting plate 211, a first end plate 212 and a second end plate 213.

[0057] Wherein, the first end plate 212 and the second end plate 213 are respectively connected to both ends of the connecting plate 211. One end of the rotating connecting piece 220 is connected to the first end plate 212, and the other end of the rotating connecting piece 220 is connected to the second end plate 213. The locking teeth 231 are arranged on the manual adjustment part 230. A locking mating rack 214 is arranged on the side of the connecting plate 211 close to the manual adjustment part 230. The locking teeth 231 are adapted to the locking mating rack 214. In the state of the pressing locking position, the locking teeth 231 are meshed and locked on the locking mating rack 214.

[0058] For example, as Figures 5 to 7As shown, the first end plate 212 and the second end plate 213 are respectively connected to both ends of the connecting plate 211. And the first end plate 212 and the second end plate 213 are located on the same side of the connecting plate 211, parallel to each other, and both are perpendicular to the connecting plate 211. One end of the pin shaft is connected to the first end plate 212, and the other end of the pin shaft is connected to the second end plate 213. The manual adjustment part 230 is rotatably connected to the pin shaft. A locking tooth 231 is provided on the manual adjustment part 230. The locking tooth 231 includes multiple sub-teeth. A locking engagement rack 214 is provided on one side of the connecting plate 211 close to the manual adjustment part 230. When the manual adjustment part 230 is pressed, the locking tooth 231 on the manual adjustment part 230 can be engaged and locked at a certain position of the locking engagement rack 214. When the manual adjustment part 230 is lifted, the locking tooth 231 on the manual adjustment part 230 can be separated from the locking engagement rack 214. That is to say, when the locking device 200 is switched to the pressing and locking position, one end of the connecting plate 211 is clamped in the second locking groove 303, the manual adjustment part 230 is clamped in the first locking groove 103, and the locking tooth 231 on the manual adjustment part 230 is engaged and locked at a certain position of the locking engagement rack 214. Thus, the locking connection force between the bucket tooth 100 and the tooth seat 300 by the locking device 200 can be further strengthened, so that the bucket tooth 100 is more reliably locked and connected to the tooth seat 300. When the locking device 200 is switched to the lifting and unlocking position, the manual adjustment part 230 is separated from the first locking groove 103, and the locking tooth 231 on the manual adjustment part 230 is separated from the locking engagement rack 214 on the connecting plate 211. By pushing the connecting plate 211, the connecting plate 211 can be separated from the second locking groove 303.

[0059] It should be pointed out here that the above embodiments are only illustrative embodiments of the present invention and cannot constitute any limitation to the present invention. That is to say, the enhanced locking structure provided between the manual adjustment part 230 and the connecting plate 211 includes but is not limited to the locking tooth 231 and the locking engagement rack 214. For example, in other embodiments of the present invention, a cam mechanism or the like can also be provided between the manual adjustment part 230 and the connecting plate 211.

[0060] In another embodiment of the present invention, elongated holes 215 are provided on both the first end plate 212 and the second end plate 213. Both ends of the rotating connecting member 220 are respectively slidably connected to the corresponding elongated holes 215 to adjust the locking position of the locking tooth 231 and the locking engagement rack 214.

[0061] Refer to Figure 5 and Figure 6A description is given. The elongated holes 215 on the first end plate 212 are flush with the elongated holes 215 on the second end plate 213. The length direction of each elongated hole 215 is the same as the layout direction of the locking and mating rack 214 on the connecting plate 211. One end of the pin shaft is slidably connected into the elongated hole 215 of the first end plate 212, and the other end of the pin shaft is slidably connected into the elongated hole 215 of the second end plate 213. Thus, the pin shaft can drive the manual adjustment part 230 to move along the length direction of the elongated hole 215. That is to say, the pin shaft can drive the manual adjustment part 230 to move along the layout direction of the locking and mating rack 214. Furthermore, the meshing and locking position of the locking teeth 231 on the manual adjustment part 230 and the locking and mating rack 214 on the connecting plate 211 can be adjusted so that the manual adjustment part 230 can always be clamped in the first locking groove 103. Thus, the locking device 200 can be applicable to the bucket assemblies with first mounting holes 102 and second mounting holes 301 of different sizes, improving the versatility of the locking device 200.

[0062] In an embodiment of the present invention, in the pressed locking state, one side of the connecting plate 211 is limited and clamped in the second locking groove 303. An elastic pad 240 is arranged between the connecting plate 211 and the limiting side wall 302. The elastic pad 240 is used to provide a reverse extrusion force for the connecting plate 211 to increase the locking force between the manual adjustment part 230 and the first locking groove 103.

[0063] Specifically, as Figures 5 to 7 shown, an elastic pad 240 is arranged between the connecting plate 211 and the limiting side wall 302. Among them, the elastic pad 240 can be connected to the end of the connecting plate 211 or can be connected to the limiting side wall 302. In this embodiment, the elastic pad 240 is connected to the end of the connecting plate 211. When the bucket tooth 100 needs to be locked and connected to the tooth seat 300, first place the locking device 200 from the outer opening of the first mounting hole 102 into the locking installation area; move the locking device 200 towards the side close to the second locking groove 303 so that the elastic pad 240 and the connecting plate 211 are clamped in the second locking groove 303; press the manual adjustment part 230 so that the manual adjustment part 230 is clamped in the first locking groove 103 and the locking teeth 231 on the manual adjustment part 230 are meshed and locked on the locking and mating rack 214. At this time, the elastic pad 240 is compressed, and the elastic pad 240 can generate a reverse extrusion force on the connecting plate 211, and then the connecting plate 211 drives the manual adjustment part 230 to press forcefully into the first locking groove 103. Thus, the pressing force between the manual adjustment part 230 and the first locking groove 103 can be enhanced, greatly improving the connection reliability between the bucket tooth 100 and the tooth seat 300.

[0064] In addition, the elastic pad 240 between the connecting plate 211 and the limiting side wall 302 can be replaced with other elastic components, such as a spring, etc.

The lifting opening 232 is used to lift and flip the manual adjustment part 230 so that the manual adjustment part 230 is switched to the lifting unlocking position. As Figure 5 and Figure 6 shown, two branches are formed on the manual adjustment part 230, and the lifting opening 232 is formed between the two branches. When it is necessary to switch the locking device 200 to the pressing locking position, the two branches of the manual adjustment part 230 can be manually pressed. When it is necessary to switch the locking device 200 to the lifting unlocking position, a hand or a related tool can be inserted into the bottom of the two branches through the lifting opening 232 for lifting operation. The operation process is labor-saving and time-saving.

[0066] In another embodiment of the present invention, at least one locking device 200 is provided between the bucket tooth 100 and the tooth seat 300.
