A bucket assembly and a work machine according to an embodiment of the present invention will be described with reference to fig. 1 to 7. It should be understood that the following description is only exemplary embodiments of the present invention and does not constitute any particular limitation of the present invention.

An embodiment of the first aspect of the present invention provides a hydraulic control system, as shown in fig. 1 to 4, the bucket assembly includes a bucket body, a tooth 100, and a lock device 200.

Wherein, the bucket body is provided with a tooth holder 300. The teeth 100 are provided with insertion holes 101. The teeth 100 are inserted into the tooth holder 300 through the insertion holes 101. The locking device 200 is installed between the block 300 and the tooth 100. The locking device 200 is capable of switching between a depressed locking position and a pulled unlocking position. In the state that the locking position is pressed, the bucket tooth 100 is connected with the tooth holder 300 in a locking way; in the pulled unlocked state, the tooth 100 can be separated from the tooth holder 300.

In the bucket assembly of the present invention, the bucket body is provided with a plurality of tooth holders 300 at intervals. Each tooth holder 300 is provided with a corresponding bucket tooth 100. Specifically, the bucket tooth 100 is provided with an insertion hole 101 adapted to the tooth holder 300. The tooth 100 can be inserted into the tooth holder 300 through the insertion hole 101. The locking device 200 is installed between the tooth holder 300 and the tooth 100. The locking device 200 is manually pushed or pulled to switch between a pushed locked position and a pulled unlocked position. As shown in fig. 1 and 2, in a state where the lock position is pressed, the lock device 200 locks the tooth 100 to the tooth holder 300, and the tooth 100 cannot be disengaged from the tooth holder 300. As shown in fig. 3 and 4, in the pulled-up unlocked position, the locking device 200 cannot lockingly connect the tooth 100 and the toothholder 300, and the tooth 100 and the toothholder 300 can be separated from each other by pulling the tooth 100 along a side away from the toothholder 300.

In the process of replacing the bucket tooth 100, firstly, the locking device 200 is pulled up to be converted into a pulling unlocking position; the locking device 200 is then removed, and the tooth 100 is pulled along the side away from the block 300 to separate the tooth 100 from the block 300. Subsequently, a new tooth 100 is inserted into the tooth holder 300, the lock device 200 is installed between the tooth holder 300 and the tooth 100, and the lock device 200 is pressed to be shifted to the press-lock position, at which time the new tooth 100 is lock-connected to the tooth holder 300.

With this arrangement, the tooth 100 is inserted into the tooth holder 300 through the insertion hole 101, and the lock device 200 is mounted between the tooth 100 and the tooth holder 300. In the process of replacing the bucket tooth 100, the locking device 200 is manually pressed or pulled to be switched between a pressing locking position and a pulling unlocking position, and therefore the bucket tooth 100 is detached and installed. The operation process is trouble-saving and labor-saving, and has no safety threat to workers.

In one embodiment of the present invention, the tooth 100 is provided with a first mounting hole 102. The toothholder 300 is provided with a second mounting hole 301. The first mounting hole 102 and the second mounting hole 301 together constitute a lock mounting region. The lock device 200 is mounted into the lock mounting area. A first locking groove 103 is provided in the first mounting hole 102. The second mounting hole 301 includes a stopper sidewall 302. The first locking groove 103 and the limiting side wall 302 are oppositely arranged along the insertion direction of the bucket tooth 100.

Under the state of pressing the locking position, two 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 teeth 100 and the tooth holder 300 from being separated from each other;

in the pulled unlocking state, both ends of the locking device 200 can be separated from the first locking groove 103 and the stopper sidewall 302, respectively, so that the tooth 100 can be separated from the tooth holder 300.

For example, as shown in fig. 2 and 4, the first mounting hole 102 of the tooth 100 extends through a sidewall of the tooth 100. Or, the first mounting hole 102 on the tooth 100 communicates the outer side of the tooth 100 with the inner cavity of the insertion hole 101. The first mounting hole 102 communicates with a second mounting hole 301 of the carrier 300, and constitutes a lock mounting area together with the second mounting hole 301. The locking device 200 is mounted into the lock mounting area from the outer opening of the first mounting hole 102.

The side wall of the first mounting hole 102 is provided with a first locking groove 103, and the side wall of one side of the second mounting hole 301 is a limiting side wall 302. The tooth 100 is inserted into the tooth holder 300 through the insertion hole 101, and the tooth 100 may move only in the insertion direction. Thus, the first lock groove 103 and the stopper side wall 302 are provided so as to face each other in the insertion direction of the tooth 100, and a stopper effect is exerted on the tooth 100 in the insertion direction.

Specifically, as shown in fig. 2, the locking device 200 is locked downward and is shifted to the pressed locking position, in which one end of the locking device 200 is pressed into the first locking groove 103 of the tooth 100 and the other end of the locking device 200 is pressed against the stopper side wall 302 of the tooth holder 300. This prevents the tooth 100 from moving in the insertion direction. That is, the tooth 100 is lockingly coupled to the block 300.

As shown in FIG. 4, the locking device 200 is pulled upward to be shifted to the pulled unlocking position, and at this time, one end of the locking device 200 is turned to the outside of the 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 may be moved within the locking region to a position where the other end of the locking device 200 is separated from the stopper sidewall 302. Subsequently, the lock device 200 is taken out of the lock installation region. The tooth 100 is pulled toward a side away from the tooth holder 300, so that the tooth 100 is separated from the tooth holder 300.

In one embodiment of the present invention, the locking device 200 includes a bracket 210, a rotational link 220, and a manual adjustment part 230. The manual adjusting portion 230 is rotatably connected to the bracket 210 through the rotating link 220. The hand-manipulated portion 230 is rotatable with respect to the bracket 210 to switch between a depressed locked position and a pulled unlocked position.

In the state of pressing the locking position, the manual adjusting part 230 is rotatably clamped in the first locking groove 103, and the bracket 210 can be clamped in the limiting side wall 302; in a state where the unlocking position is pulled up, the manual adjustment portion 230 is rotated to a position separated from the first locking groove 103, and the holder 210 can be moved to a position separated from the stopper side wall 302.

Further, in an embodiment of the present invention, an edge of the first mounting hole 102 near the position-limiting side wall 302 extends to an inner side of a corresponding edge of the second mounting hole 301, so that the position-limiting side wall 302 and the tooth 100 together form a second locking groove 303. The second locking groove 303 is used to engage the bracket 210 to prevent the locking device 200 from being removed from the locking installation region.

Specifically, as shown in fig. 2, 4 to 7, the manual adjustment portion 230 is rotatably coupled to the bracket 210 by a rotary coupling member 220. For example, the rotational connection 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 tooth 100, a first locking groove 103 is provided on one side wall of the first mounting hole 102, and the side wall is aligned with a corresponding side wall of the second mounting hole 301. The other side wall of the first mounting hole 102 is located inside the corresponding side wall of the second mounting hole 301, or the other side wall of the first mounting hole 102 protrudes to the inside of the corresponding side wall of the second mounting hole 301, i.e. the limiting side wall 302. Thus, a second locking groove 303 is formed among the bottom of the tooth 100, the limiting side wall 302 and the bottom of the second mounting hole 301.

When the lock device 200 is installed, the lock device 200 is placed in the lock installation area through the outer opening of the first installation hole 102. When the locking device 200 needs to be switched to the pressing locking position, the bracket 210 is moved to a position where one end of the bracket is clamped in the second locking groove 303, and then the manual adjusting part 230 is pressed downwards, so that the manual adjusting part 230 is limited to be clamped in the first locking groove 103. Thereby, the locking device 200 locks and connects the tooth 100 to the tooth holder 300. When the locking device 200 needs to be switched to the lifting unlocking position, the hand adjusting part 230 is lifted upwards, so that the hand adjusting part 230 moves to the outer side of the bucket tooth 100 and is separated from the first locking groove 103. The holder 210 is then moved to the side away from the second locking groove 303 until the holder 210 is completely disengaged from the second locking groove 303. The locking device 200 is then removed and the tooth 100 is pulled away from the block 300.

In one embodiment of the present invention, the bracket 210 includes a connection plate 211, a first end plate 212, and a second end plate 213.

Wherein the first end plate 212 and the second end plate 213 are connected to both ends of the connection plate 211, respectively. One end of the rotational link 220 is connected to the first end plate 212, and the other end of the rotational link 220 is connected to the second end plate 213. The locking teeth 231 are provided on the manual adjustment part 230. The side of the connecting plate 211 close to the manual adjusting part 230 is provided with a locking matching rack 214. The locking teeth 231 are adapted to the locking engagement rack 214. In the state where the lock position is pressed, the lock teeth 231 are engaged and locked to the lock engagement rack 214.

For example, as shown in fig. 5 to 7, the first and second end plates 212 and 213 are connected to both ends of the connection plate 211, respectively. And the first end plate 212 and the second end plate 213 are located on the same side of the connecting plate 211, are parallel to each other, and are both perpendicular to the connecting plate 211. One end of the pin is connected to the first end plate 212 and the other end of the pin is connected to the second end plate 213. The manual adjustment part 230 is rotatably connected to the pin. The manual adjustment portion 230 is provided with a locking tooth 231. The locking teeth 231 comprise a plurality of partial teeth. The side of the connecting plate 211 close to the manual adjusting part 230 is provided with a locking matching rack 214. When the manual adjusting portion 230 is pressed, the locking teeth 231 on the manual adjusting portion 230 can be engaged and locked at a certain position of the locking engagement rack 214. When the manual adjustment part 230 is pulled, the locking teeth 231 on the manual adjustment part 230 can be separated from the locking engagement rack 214. That is, when the locking device 200 is switched to the pressing locking position, one end of the connecting plate 211 is engaged in the second locking groove 303, the manual adjustment portion 230 is engaged in the first locking groove 103, and the locking teeth 231 on the manual adjustment portion 230 are engaged and locked at a position of the locking engagement rack 214. Thereby, the locking connection force of the locking device 200 to the tooth 100 and the tooth holder 300 can be further enhanced, so that the tooth 100 can be more reliably locked and connected to the tooth holder 300. When the locking device 200 is switched to the lifting unlocking state, the manual adjusting part 230 is separated from the first locking groove 103, and the locking teeth 231 on the manual adjusting part 230 are separated from the locking matching racks 214 on the connecting plate 211. The connection plate 211 is pushed to separate the connection plate 211 from the second locking groove 303.

It should be noted that the above-mentioned embodiment is only an illustrative embodiment of the present invention, and does not limit the present invention in any way. That is, the reinforcing locking structure provided between the hand-manipulated portion 230 and the connection plate 211 includes, but is not limited to, the locking teeth 231 and the lock engagement rack 214. For example, in other embodiments of the present invention, a cam mechanism or the like may be further provided between the manual adjustment portion 230 and the connection plate 211.

In yet another embodiment of the present invention, the first end plate 212 and the second end plate 213 are each provided with an elongated hole 215. The two ends of the rotary connecting member 220 are slidably connected to the corresponding elongated holes 215, respectively, to adjust the locking position of the locking teeth 231 and the locking engagement rack 214.

As described with reference to fig. 5 and 6, the elongated holes 215 of the first end plate 212 are flush with the elongated holes 215 of the second end plate 213. The longitudinal direction of each elongated hole 215 is the same as the arrangement direction of the lock engagement rack 214 on the link plate 211. One end of the pin is slidably coupled into the elongated hole 215 of the first end plate 212 and the other end of the pin is slidably coupled into the elongated hole 215 of the second end plate 213. Thus, the pin can move the manual adjustment part 230 along the length direction of the elongated hole 215. That is, the pin shaft can drive the manual adjusting portion 230 to move along the arrangement direction of the locking engagement rack 214, and then, the engagement locking position of the locking teeth 231 on the manual adjusting portion 230 and the locking engagement rack 214 on the connecting plate 211 can be adjusted, so that the manual adjusting portion 230 can be always clamped in the first locking groove 103. Therefore, the locking device 200 can be applied to bucket assemblies with the first mounting hole 102 and the second mounting hole 301 of different sizes, and the universality of the locking device 200 is improved.

In one embodiment of the present invention, in the press-locked state, one side stopper of the connection plate 211 is placed 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 serves to provide a counter pressing force to the coupling plate 211 to increase a locking force between the manual-adjusting portion 230 and the first locking groove 103.

Specifically, as shown in fig. 5 to 7, an elastic pad 240 is provided between the connection plate 211 and the stopper sidewall 302. The elastic pad 240 may be connected to an end of the connection plate 211, or may be connected to the position-limiting sidewall 302. In this embodiment, the elastic pad 240 is connected to an end of the connection plate 211. When the bucket tooth 100 needs to be locked and connected to the tooth holder 300, the locking device 200 is placed in a locking installation area from an outer opening of the first installation hole 102; moving the locking device 200 to a 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; the manual adjustment portion 230 is pressed to make the manual adjustment portion 230 be clamped in the first locking slot 103, and the locking teeth 231 on the manual adjustment portion 230 are engaged and locked on the locking 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 connection plate 211, so that the connection plate 211 drives the manual adjustment portion 230 to be pressed against the first locking groove 103. Therefore, the abutting force between the manual adjusting part 230 and the first locking groove 103 can be enhanced, and the connection reliability between the bucket tooth 100 and the tooth holder 300 is greatly improved.

In addition, the elastic pad 240 between the connection plate 211 and the position-restricting side wall 302 may be replaced with other elastic members, such as a spring, etc.

In one embodiment of the present invention, the manual adjustment portion 230 is provided with a lifting opening 232. The lift opening 232 is used to lift the flip handle portion 230 to transition the handle portion 230 to a lift unlocked position. As shown in fig. 5 and 6, the manual adjustment portion 230 is formed with two branches, and a lifting opening 232 is formed between the two branches. When it is necessary to switch the locking device 200 to the pressed locking position, both branches of the manual adjustment part 230 may be manually pressed.
