[0002] When filling the dam, a compactor is needed to compact the earth. However, during the filling process, some stones are easily scattered on the road surface. If these stones are not removed, the compactor will directly press down the stones, and the presence of some larger stones will hinder the mutual squeezing between soil particles, resulting in the failure to compact the surrounding of the stones, and the overall compaction effect cannot be achieved. In the later stage, the stones are easy to fall off, affecting the quality of compaction. Therefore, how to solve this problem is what we need to consider. Utility Model Content

DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] Reference Figure 1-Figure 4 The earthwork compaction device for dam filling comprises two fixed plates 1, between which a pressure roller 2 is rotatably connected, one side of one of the fixed plates 1 is fixedly connected to two mounting blocks 3, a rack 4 is arranged between the two mounting blocks 3, both ends of the rack 4 respectively penetrate the corresponding mounting blocks 3 and extend to the outside, a fixed block 5 is fixedly connected to the inner side wall of one of the fixed plates 1, one end of the rack 4 is sleeved with a spring 6, one end of the spring 6 is fixedly connected to one end of one of the mounting blocks 3, and the other end of the spring 6 is fixedly connected to one end of the fixed block 5, a rotating shaft 7 is rotatably connected to one side of one of the fixed plates 1, a driving mechanism for driving the rotating shaft 7 to rotate is arranged on one side of one of the fixed plates 1, and the driving mechanism comprises a motor 8 installed on the side wall of one of the fixed plates 1, and the end of the output shaft of the motor 8 penetrates the corresponding fixed plate 1 and is fixedly connected to one end of the rotating shaft 7.
[0021] Among them, a half gear 9 is installed on the outer wall of the rotating shaft 7, and the half gear 9 is meshed with the rack 4. One side of the rack 4 is fixedly connected with a connecting block 10, and one end of the connecting block 10 is fixedly connected with a collecting frame 13. Through the rotation of the half gear 9, when the teeth on it rotate to the bottom, the rack 4 meshed with it will move in the direction close to the pressure roller 2. At this time, the spring 6 is compressed. When the teeth on it rotate to the top, the rack 4 will return to its original position under the elastic action of the spring 6. The half gear 9 continues to rotate, so that the rack 4 moves back and forth, and then the collecting frame 13 moves back and forth, and the stones inside are filtered out to prevent the stones from being pressed down, resulting in the lack of compaction around the stones and the failure to achieve the overall compaction effect. A slide groove 11 is provided on one side of the other fixed plate 1, and a slider 12 is slidably connected in the slide groove 11. One end of the slider 12 is fixedly connected to one side of the collecting frame 13, and the slider 12 and the connecting block 10 move the collecting frame 13 together, and the slider 12 guides the movement of the collecting frame 13.
[0022] Among them, a plurality of shovel blocks 14 are fixedly connected to the bottom of one side of the collecting frame 13, and a protective layer is arranged on the outer sides of the plurality of shovel blocks 14, and the plurality of protective layers are made of wear-resistant material. A plurality of through holes 15 are provided at the inner bottom of the collecting frame 13, and the soil will return to the ground through the through holes 15, while the stones will remain inside the collecting frame 13. Guide rails 16 are installed on the outer walls of both sides of the collecting frame 13, and moving blocks 17 are slidably connected to the opposite sides of the two guide rails 16, and baffles 18 are fixedly connected to the opposite sides of the two moving blocks 17. A strip-shaped opening cooperating with the baffles 18 is provided at the upper end of the collecting frame 13, and the baffles 18 are slidably connected to the inner walls of both sides of the collecting frame 13. When the collecting frame 13 moves toward the direction of the pressure roller 2, the baffles 18 will move down to cover the collecting frame 13 to prevent stones from falling during the movement and affecting the collection and filtering effect. When the collecting frame 13 returns to its original position, the baffles 18 will return to its original position to facilitate the collecting frame 13 to collect stones.
[0023] When the utility model is in use, the compacting device is installed at the front of the roller to drive the compacting device forward. When the compacting device moves forward, the collecting frame 13 is located in front of the pressing roller 2 and collects stones before the pressing roller 2 to prevent the pressing roller 2 from pressing the stones into the soil. During the movement, the motor 8 and the two guide rails 16 can be started. After the motor 8 is started, the rotating shaft 7 is rotated, thereby driving the half gear 9 to rotate. When the teeth on the half gear 9 rotate to the bottom, it will drive the rack 4 meshing with it to move in the direction close to the pressing roller 2, thereby causing the collecting frame 13 to move to the bottom of the roller 2. The rack 4 moves in the direction close to the pressure roller 2, and the spring 6 is compressed at this time. When the teeth on the half gear 9 rotate upward, the rack 4 will return to the original position with the collecting frame 13 due to the elastic effect of the spring 6. When the teeth of the half gear 9 rotate downward again, the rack 4 will move the collecting frame 13 in the direction close to the pressure roller 2. By continuously rotating the half gear 9, the rack 4 will continuously reciprocate with the collecting frame 13 to filter out the stones and soil in the collecting frame 13. The soil will fall to the ground along the multiple through holes 15, while the stones will remain in the collecting frame 13.
[0024] After the two guide rails 16 are started, they will move the corresponding moving blocks 17 up and down, and then move the baffle 18 up and down. When the collecting frame 13 moves toward the direction close to the pressure roller 2, the baffle 18 moves down to block the collecting frame 13 to prevent stones from falling from the collecting frame 13 during the filtering process and affecting the collection and filtering effect. When the collecting frame 13 returns to its original position, the baffle 18 will also return to its original position, making it convenient for the collecting frame 13 to move and collect stones. Through the reciprocating movement of the collecting frame 13 and the up and down movement of the baffle 18, the stones are filtered out to prevent them from being pressed down and affecting the mutual squeezing between soil particles, which in turn causes the areas around the stones to be not compacted and affects the overall compaction effect.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
