Detailed Description

The invention is further described with reference to the drawings and the detailed description.

As shown in fig. 1 to 4, the present invention includes a vehicle body 6 and an excavating device.

The excavator is characterized in that a lifting arm 5 is arranged on the vehicle body 6, the head end of the lifting arm 5 is hinged to the vehicle body 6, and the excavating device is installed at the tail end of the lifting arm 5. The lifting arm 5 is driven to move up and down by a hydraulic cylinder or other devices between the lifting arm 5 and the vehicle body 6. The vehicle body 6 is internally provided with a power source, such as an engine, and the lifting arm 5 is internally provided with a power transmission mechanism, such as a chain wheel and chain structure, a transmission shaft structure and the like. The excavating device can be driven to move up and down by the action of the lifting arm 5, so that the excavating depth can be adjusted.

The excavating device comprises a main shaft 10, a bucket 1, a fixed disc 9, a rotary disc 4, a clockwork spring 8 and a guide plate 3.

Two ends of the main shaft 10 are arranged at the tail end of the lifting arm 5, and the main shaft 10 is driven to rotate through a power transmission mechanism. The fixed disk 9 is fixed to the main shaft 10 so as to be rotatable in synchronization with the main shaft 10. The turntable 4 is a hollow cylindrical shell structure, the spindle 10 penetrates through the axis of the turntable 4, and the fixed disk 9 is positioned in the inner cavity of the turntable 4. The turntable 4 is rotatable about a spindle 10. A clockwork spring 8 is arranged between the fixed disc 9 and the rotary disc 4, and two ends of the clockwork spring 8 are respectively fixed on the fixed disc 9 and the rotary disc 4. When the fixed disc 9 rotates with the spindle 10, the turntable 4 is pulled to rotate by the clockwork spring 8.

Since the bucket 1 is oriented differently, for convenience of description, the orientation of the bucket 1 directly above the main shaft 10 is defined as a direction related to the structure of the bucket 1. Wherein the turning direction of the bucket 1 is forward and the direction opposite to the turning direction is backward.

The buckets 1 are uniformly arranged on the periphery of the rotating disc 4. A spring plate 11 is fixedly arranged between the bucket 1 and the rotary table 4, and the spring plate 11 is obliquely distributed along the direction from front to bottom to back. The upper wall of the bucket 1 is inclined in a front-up to rear-down direction, and a series of teeth 12 are provided on the front edge of the upper wall of the bucket 1 to increase the excavating performance of the bucket 1. The front wall of the bucket 1 is located at the lower front side of the bucket 1, and the upper front side of the bucket 1 is provided with an opening so that excavated earth and sand can enter the bucket 1. The lower edges of the left side wall 7 and the right side wall 7 of the bucket 1 are hinged with the bucket 1, wherein a torsional spring is arranged at the hinged position, and the side walls 7 are in a closed state in a natural state under the elastic action of the torsional spring. After the side walls 7 are opened, the sand in the bucket 1 can fall out from two sides of the bucket 1, the middle of the lower wall of the bucket 1 is high, and the left side and the right side are low, so that the sand in the bucket 1 is promoted to slide to two sides of the bucket 1. The lower edge of the side wall 7 is fixedly provided with an extension part which extends downwards. The side wall 7 can be opened by pushing on the extension.

The positions on the two sides of the rotary table 4 are respectively provided with an arc-shaped rod 2, and the arc-shaped rods 2 are fixed on the lifting arm 5 through connecting rods. The middle position of the arc-shaped rod 2 is an arc-shaped structure taking the main shaft 10 as the center of a circle, and the positions of the two ends of the arc-shaped rod 2 gradually approach the main shaft 10. When the extending part of the side wall 7 of the bucket 1 rotates to the position of the arc-shaped rod 2, the extending part is jacked upwards through the action of the arc-shaped rod 2, so that the side wall 7 is opened, and the sand and soil in the bucket 1 can slide out of the side wall 7 and fall down. The lower part of the arc-shaped rod 2 is respectively provided with a guide plate 3, the guide plates 3 are fixed on the lifting arm 5, the inner sides (close to one side of the turntable 4) of the guide plates 3 are high, and the outer sides (far away from one side of the turntable 4) are low. The sandy soil which slides out of the side wall 7 falls on the guide plate 3, and the guide sandy soil can slide outwards under the action of the guide plate 3 to prevent the sandy soil from sliding into the ditch.

The working process is as follows: when the excavator works, the power source drives the excavating device to rotate through the power transmission mechanism, the bucket 1 excavates the ground, and the excavator body 6 drives the excavating device to move forwards, so that the excavating effect of a ditch can be realized. 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.

Dig out the in-process sand and soil fall into scraper bowl 1 in, scraper bowl 1 is along with 4 during upwards rotations to 4 tops of carousel, open scraper bowl lateral wall 7 through arc pole 2, thereby the sand and soil in the scraper bowl 1 can come out from 1 both sides landing of scraper bowl, the sand and soil that slides out falls on guide plate 3, effect through guide plate 3 with sand and soil landing to the bottom surface of irrigation canals and ditches both sides, and make soil heap and irrigation canals and ditches keep certain distance, prevent that sand and soil from sliding into in the irrigation canals and ditches once more.

When a stone block is encountered in the excavation process, as shown in fig. 4, the bucket 1 is squeezed under the action of the stone block, the spring plate 11 is bent, and the bucket 1 is retracted backwards, so that the bucket 1 can go around the stone block to continue rotating upwards, and the machine can be prevented from being flameout due to the fact that the bucket 1 is jammed; the resistance to which the rotating disc 4 is subjected increases during this process, thereby tightening the clockwork spring 8; after the scraper bowl 1 bypasses the stone, the resistance disappears, the clockwork spring 8 resets to drive the rotary table 4 to rotate rapidly, the next scraper bowl 1 rotates to the stone rapidly to impact the stone acutely, and the stone can be crushed or knocked out from the soil after one or more times of impact.

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.
