The stop mechanism comprises a fixed cylinder 13, a telescopic plate 14 and a first driving piece, wherein the fixed cylinder 13 is arranged on the bucket body 1; the expansion plate 14 is connected with the fixed cylinder 13 and can slide relative to the fixed cylinder 13, and the first driving piece can drive the expansion plate 14 to move along the height direction of the bucket body 1 so as to shield or open the feeding hole. The fixed cylinder 13 is formed in a square cylindrical shape as a whole, and the expansion plate 14 can smoothly slide in the fixed cylinder 13.

When the material needs to be crushed, the expansion plate 14 is driven to slide relative to the fixed cylinder 13 through the first driving piece, the feed inlet is shielded by the downward movement of the expansion plate 14 along the height direction of the bucket body 1, and the material can be prevented from flying out of the bucket body 1 when the passive jaw plate 3 and the fixed jaw plate 4 are crushed. When the bucket body 1 needs to be fed, the first driving piece drives the telescopic plate 14 to slide relative to the fixed cylinder 13, and the telescopic plate 14 moves upwards along the height direction of the bucket body 1 to open a feeding hole, so that feeding can be carried out.

It will be appreciated that the specific structure of the first driving member may be varied, as long as the telescopic plate 14 can be driven to slide relative to the fixed cylinder 13, and the telescopic plate 14 can be driven to move downwards along the height direction of the bucket body 1. Illustratively, the first driving member includes a driving motor 19, a pulling rope 18, a mounting block 15 and an elastic expansion member 17; the mounting block 15 is connected with the telescopic plate 14, and two ends of the elastic telescopic piece 17 are respectively connected with the main body of the driving motor 19 and the mounting block 15; one end of the pull rope 18 is wound on a power output shaft of the driving motor 19, and the other end of the pull rope 18 is connected with the mounting block 15; the drive motor 19 is fixed to the bucket body 1 via a fixing plate 16. Illustratively, the elastic expansion member 17 is a spring.

When the bucket main part 1 feeding is needed, the driving motor 19 runs, the power output shaft of the driving motor 19 rotates, the pull rope 18 continuously winds, the mounting block 15 is driven to move upwards along the height direction of the bucket main part 1, meanwhile, the spring is compressed, the expansion plate 14 slides relative to the fixed cylinder 13 and moves upwards along the height direction of the bucket main part 1, and therefore the feeding opening is opened to feed. When the material needs to be crushed, the power output shaft of the driving motor 19 rotates towards the opposite direction, so that the pull rope 18 is unreeled, the compressed spring acts on the mounting block 15, the mounting block 15 moves downwards along the height direction of the bucket body 1, the telescopic plate 14 is driven to slide relative to the fixed cylinder 13 and move downwards along the height direction of the bucket body 1 to shield the feeding hole, and the material can be prevented from flying out of the bucket body 1 when being crushed by the jaw plates 3 and the jaw plates 4.

Further, the crushing bucket 100 further comprises a rotating plate 12 and a second driving member, wherein the second driving member can drive the rotating plate 12 to move so as to shield or open the discharge hole.

When needs are smashed the material, through the motion of second driving piece drive rotor plate 12 and shelter from the discharge gate, then can make by the crushing material can not discharged, and then make the material can smash fully in bucket main part 1, after the completion of fully smashing, open the discharge gate through the motion of second driving piece drive rotor plate 12, can be with the whole discharge bucket main part 1 of the material after smashing.

Alternatively, the rotating plate 12 can be used to block or unblock the spout by swinging. Illustratively, one end of the rotating plate 12 is rotatably connected with the bucket body 1 through a rotating shaft, and the second driving member is used for driving the rotating plate 12 to swing around the rotating shaft so as to shield or open the discharge port.

Further, the second driving member includes a fixing block 10 and an electric push rod 11 mounted on the fixing block 10, the fixing block 10 is mounted on the bucket body 1, and an end of the electric push rod 11 is hinged to the rotating plate 12.

By controlling the extension of the push rod part of the electric push rod 11, the rotating plate 12 can be driven to swing around the rotating shaft in the direction away from the bucket body 1, so that the discharge port can be opened to discharge all the crushed materials out of the bucket body 1. By controlling the retraction of the rod portion of the electric push rod 11, the rotating plate 12 can be driven to swing around the rotating shaft in a direction approaching the bucket body 1, and the discharge port can be blocked.

The operation principle of the crushing bucket 100 of the present embodiment is as follows:

when the bucket main part 1 feeding is needed, the driving motor 19 runs, the power output shaft of the driving motor 19 rotates, the pull rope 18 continuously winds, the mounting block 15 is driven to move upwards along the height direction of the bucket main part 1, meanwhile, the spring is compressed, the expansion plate 14 slides relative to the fixed cylinder 13 and moves upwards along the height direction of the bucket main part 1, and therefore the feeding opening is opened to feed.

After the feeding is finished, when the material needs to be crushed, the power output shaft of the driving motor 19 rotates in the opposite direction, so that the pull rope 18 is unreeled, the compressed spring acts on the mounting block 15, the mounting block 15 moves downwards along the height direction of the bucket body 1, and the telescopic plate 14 is driven to slide relative to the fixed cylinder 13 and move downwards along the height direction of the bucket body 1 to shield the feeding hole.
