Since the bucket 1 is oriented differently, for convenience of description, the orientation of the bucket 1 in front of the main shaft 12 is the reference when referring to the direction related to the structure of the bucket 1.

The bucket 1 is of a shell structure with an upper opening. The rear side of the bucket 1 is fixed to the turntable 2 and the upper edge of the front wall of the bucket 1 is provided with a series of teeth 13 to increase the digging performance of the bucket 1. The bucket 1 is wide at the top and narrow at the bottom. The lateral wall 14 lower limb of one side is articulated mutually with scraper bowl 1 main part, and lateral wall 14 can outwards be opened, and after lateral wall 14 opened, the interior sand and soil of scraper bowl 1 can outwards slide out along lateral wall 14. The lower wall of the bucket 1 is inclined with one end adjacent to the openable side wall 14 being lowered and the other end being raised, thereby facilitating the sand in the bucket 1 to slide outward.

As shown in fig. 5, a spring 15 is provided between the bucket side wall 14 and the bucket 1, the head end of the spring 15 is fixed at a point B of the bucket 1, the tail end of the spring 15 is fixed to the side wall 14, the position is set to a when the side wall 14 is closed, and when the position is set to a' after the side wall 14 is fully opened, the hinge point between the side wall 14 and the bucket 1 is set to O, the position of the point B at the head end of the spring 15 satisfies: point O is located inside the triangle defined by the three points A, B, A' so that the position of the side wall 14 can be fixed when the side wall 14 is closed or opened by the action of the spring 15.

As shown in fig. 5 and 6, a baffle 16 is arranged on the bucket side wall 14 near the lower end, the baffle 16 is perpendicular to the bucket side wall 14, the front half part of the baffle 16 is fixed on the bucket side wall 14, and the rear half part is positioned outside the edge of the rotary table 2. The mounting seat 3 is provided with a horizontal deflector rod 5, the head end of the horizontal deflector rod 5 is fixed on the mounting seat 3, and the tail end of the horizontal deflector rod 5 is positioned at the outer side of the edge of the turntable 2. When the rotary table 2 rotates, the water rotary table 2 of the bucket 1 moves upwards, and when the baffle 16 touches the shifting rod 5, the baffle 16 is pushed downwards through the action of the shifting rod 5, so that the side wall 14 of the bucket is opened, and sandy soil in the bucket 1 slides out of the bucket 1 and falls on two sides of a ditch.

A horizontal push rod 17 is arranged below the bucket 1, and the middle of the push rod 17 penetrates through a limiting hole, so that the push rod 17 can freely slide left and right. The edge of the side face of the rotary table 2 is provided with a horizontal rotating shaft 20, the rotating shaft 20 can rotate around the axis by a certain angle, two ends of the rotating shaft 20 are respectively and fixedly provided with a first rod 19 and a second rod 18, one end of the first rod 19 is fixed at one end, close to the main shaft 12, of the rotating shaft 20, one end of the second rod 18 is fixed at one end, far away from the main shaft 12, of the rotating shaft 20, the other end of the second rod 18 is hinged to one end of a push rod 17, and the other end of the push rod 17 is located below the bucket side wall 14. The rotating disc 2 rotates, when the bucket 1 moves downwards along with the rotating disc 2, and when the baffle 16 touches the first rod 19, the first rod 19 is pushed upwards (the up-down relation is opposite to that in the figures 4 and 5 at the moment) through the action of the shift lever 5, the second rod 18 is driven to rotate, the push rod 17 is pushed through the second rod 18, the baffle 16 is pushed through the push rod 17, and therefore the bucket side wall 14 can be closed.

The working process is as follows: during operation, power supply 23 passes through power transmission mechanism 21 and drives main shaft 12 and carousel 2 rotatory, and main shaft 12 drives the rotation of spring plate 10, and spring plate 10 pushes up on lug 9, and then promotes carousel 2 rotatory, excavates ground through scraper bowl 1, drives excavating gear through automobile body 8 and walks forward to can realize the excavation effect of irrigation canals and ditches. Because the excavation process is continuously carried out by a plurality of buckets 1, compared with an excavation mode of one shovel and one shovel of an excavator, the excavation efficiency of the device is improved by multiple times compared with that of the excavator. But the machine starts the back automatic operation often, does not need manual operation, has improved degree of automation, has saved the manpower, artifical only need monitor the running state of machine can, or carry out manual operation at special circumstances, the operation of several machines can be controlled simultaneously to one person, has saved the human cost.

The sandy soil dug out in the excavation process falls into the bucket 1, when the bucket 1 rotates upwards to the front of the main shaft 12 along with the rotary table 2, the shifting lever 5 pushes the baffle 16 to open the side wall 14 of the bucket, so that the sandy soil in the bucket 1 can slide out from one side of the bucket 1, the sandy soil slides down to the ground on two sides of the ditch under the action of the side wall 14, the soil pile keeps a certain distance from the ditch, and the sandy soil is prevented from sliding down into the ditch again. When the bucket 1 rotates 180 ° to the rear of the main shaft 12, the first lever 19 is pushed by the shift lever 5 on the other side of the turntable 2, and the bucket side wall 14 is then closed, so that excavation is continued.

When a stone block is encountered in the excavation process, as shown in fig. 2, the bucket 1 is clamped, the rotary disc 2 cannot rotate continuously, the main shaft 12 rotates continuously at the moment, the spring 15 is bent, the spring 15 bypasses the lug 9 after being bent and impacts on the next lug 9, the impact action is transmitted to the stone block through the action of the rotary disc 2 and the bucket 1, so that the stone block is impacted, and the stone block can be crushed or knocked out of soil after repeated impact actions. And meanwhile, the engine can be prevented from being blocked.

It should be noted that while the invention has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the invention.
