The limiting member 12 is movably mounted at a position close to the second end of the mounting block 1, and has a locking position and an unlocking position. The limiting member 12 may be a pull pin, a first mounting hole is formed in a position of the mounting bracket 1 near the second end of the mounting bracket, and the pull pin is movably mounted in the first mounting hole. Alternatively, the limiting member 12 is a latch-type structure. Alternatively, the stopper 12 may be a bolt or bolt detachably attached to the mount 1.
When the conveying mechanism 2 is located at the first position, the limiting member 12 is located at the locking position, and the conveying mechanism 2 is limited to move in a direction away from the mounting frame 1, so that the state that the conveying mechanism 2 is located at the first position is maintained, and the conveying mechanism 2 is prevented from sliding out of the mounting frame 1 in the running process of the working machine. When the bucket tooth 200 needs to be replaced, the limiting member 12 is switched to the unlocking position, so that the conveying mechanism 2 can move in the direction away from the mounting frame 1 under the drawing action to realize unfolding.
Furthermore, a second mounting hole is formed in the conveying mechanism 2, when the conveying mechanism 2 is located at the first position, the second mounting hole is opposite to the first mounting hole, and when the limiting part 12 is switched to the locking position, the limiting part 12 is simultaneously connected with the first mounting hole and the second mounting hole, so that the conveying mechanism 2 is tightly connected with the mounting frame 1, and the conveying mechanism 2 is prevented from moving relative to the mounting frame 1.
The present disclosure also provides a work machine that may be an excavator, shovel loader, ripper, or other work machine configured with a tool box. Taking a ripper as an example, as shown in fig. 12 to 17, this working machine includes a lower vehicle body 300 and the conveyor device 100 according to any one of the embodiments described above. The lower vehicle body 300 is provided with a tool box 31, and the mount 1 is mounted to the tool box 31.
Wherein, the mounting frame 1 of the conveying device 100 can be welded or detachably connected with the tool box 31. When the conveyance mechanism 2 is located at the second position, the conveyance mechanism 2 extends obliquely downward of the lower vehicle body 300 from the outlet of the tool box 31 in a direction away from the tool box 31.
Specifically, the mount 1 is mounted to the bottom of the tool box 31. The conveying mechanism 2 can be stored in the mounting frame 1 during transportation or operation of the working machine, and the space at the bottom of the tool box 31 can be effectively used. When the bucket tooth 200 needs to be replaced, the conveying mechanism 2 is pulled out from the mounting frame 1 and unfolded to the second position, so that the input end of the conveying mechanism 2 is connected with the tool box 31, and the output end of the conveying mechanism extends to the ground to form an inclined plane with a certain angle with the ground. Then, the tooth 200 in the tool box 31 is pushed to the conveyance mechanism 2, and the tooth 200 automatically slides down to the ground, thereby reducing the conveyance work of the tooth 200. After the replacement of the tooth 200 is completed, the conveying mechanism 2 is rotated from the second position to the third position, and then the conveying mechanism 2 is pushed into the mounting frame 1. After the conveying mechanism 2 is accommodated in the mounting rack 1, the conveying mechanism 2 can be locked to the mounting rack 1 through the limiting member 12.
As shown in fig. 12 and 13, the conveying mechanism 2 is in the first position. As shown in fig. 14, 15, 16 and 17, the conveyor 2 is in the second position. Note that, the conveying mechanism 2 in fig. 16 and 17 is provided with a guide passage 24, and when the tooth 200 is replaced, the ripping hook 400 is conveyed by the ripping arm so as to face the exit of the guide passage 24, and the tooth 200 slides down from the guide passage 24 to the vicinity of the ripping hook 400.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
