Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] Specific Embodiment 1: As Figures 1-5As shown, this embodiment describes a special roadbed filling device for gravel soil in forest wetlands in cold regions, including a base 1, a shell 2 and a cylinder 5; the upper end of the base 1 is fixedly connected to the shell 2; the upper end of the shell 2 is fixedly connected to the cylinder 5; a door 7 is hinged on the bottom end of the side of the cylinder 5, and a rotating plate 9 is connected to the middle position of the cylinder 5 through a bearing; a fixed plate 10 is fixedly connected above the rotating plate 9, and a gap is left between the rotating plate 9 and the fixed plate 10; a discharge port Ⅰ14 connected to the gap is provided on the side wall of the cylinder 5; a plurality of groups of conical holes 102 with central symmetry are provided on the fixed plate 10, and a plurality of groups of circular holes 92 with central symmetry are provided on the rotating plate 9; the lower end of the fixed plate 10 is fixed The connecting device 8 is fixedly connected, and the upper end of the connecting device 8 is connected with the corresponding conical hole 102; the fixed plate 10 is provided with a discharge port II 101 near the edge; the inner wall of the cylinder 5 is also fixedly connected with a partition plate 13; the partition plate 13 is provided with a through hole 12; the motor 3 is fixedly connected to the inner bottom surface of the shell 2; the output shaft of the motor 3 is fixedly connected with a rotating shaft 4; the rotating shaft 4 passes through the cylinder 5, the rotating plate 9, and the fixed plate 10 and is connected to the lower end of the partition plate 13 through a bearing; the rotating shaft 4 is key-connected with the rotating plate 9, and the rotating shaft 4 is connected to the fixed plate 10 through a bearing; the outer circumferential surface of the rotating shaft 4 is fixedly connected with a stirring rod 11, and the stirring rod 11 is located at the upper end of the fixed plate 10. The stirring rod 11 pushes the crushed stone to move, thereby completing the screening work.

[0016] The connecting device 8 includes a fixed cylinder 81, an arc plate 82 and a slide cylinder 83; the fixed cylinder 81 is fixedly connected to the lower end of the fixed plate 10, the slide cylinder 83 is slidably matched with the fixed cylinder 81, and the upper end of the slide cylinder 83 is fixedly connected with the arc plate 82; the lower end of the slide cylinder 83 is provided with a triangular notch 84; the upper end surface of the rotating plate 9 is fixedly connected with a plurality of sets of centrally symmetrical triangular blocks 91, the triangular blocks 91 are arc-shaped, the triangular blocks 91 are spaced apart from the circular holes 92, and the triangular blocks 91 are slidably matched with the notch 84; the lower end of the slide cylinder 83 is connected with the corresponding circular hole 92. Through the cooperation of the slide cylinder 83 and the triangular block 91, the crushed stone embedded in the conical hole 102 is pushed out or its posture is changed to make it out of the conical hole 102.

[0017] The upper end of the partition plate 13 is set as an inclined surface to facilitate discharging.

[0018] The inner wall of the cylinder 5 is fixedly connected with an arc baffle 15 at the side of the discharge port Ⅰ14. The arc baffle 15 blocks the crushed stone from passing through the discharge port Ⅰ14 and can remove it in time, thus speeding up the discharge efficiency.

[0019] The stirring rod 11 is configured in an arc shape so that the crushed stones can be pushed toward the inner wall of the cylinder 5 during the rotation of the stirring rod 11 .

[0020] A towing ring 6 is fixedly connected to the side of the base 1.

[0021] The distance between the round hole 92 farthest from the rotating shaft 4 and the inner wall of the cylinder body 5 is greater than the longest length of the gravel particles.

[0022] The working principle of the utility model is as follows: when using this device, pour the gravel into the cylinder body 5 so that it is located above the partition plate 13, and then start the motor 3. The motor 3 drives the rotating shaft 4 to rotate, and then the rotating shaft 4 drives the stirring rod 11 to rotate counterclockwise in the Figure 4 shown state, so that the gravel sliding down from the upper end of the partition plate 13 through the through hole 12 moves its position under the push of the stirring rod 11. When the gravel passes through the position of the conical hole 102, part of the gravel falls into the conical hole 102 (including the gravel with a particle size smaller than the aperture of the conical hole 102 and the slender particles), and the gravel with a particle size smaller than the minimum aperture of the conical hole 102 passes through the conical hole 102 and the fixed cylinder 81 and falls into the sliding cylinder 83. Part of the slender particles fall vertically into the sliding cylinder 83, and the other part of the slender particles are stuck horizontally in the conical hole 102; the gravel that does not enter the conical hole 102 continues to move under the push of the stirring rod 11 until it moves above the discharge port II 101, and then slides down to the upper end of the rotating plate 9. The rotation of the motor 3 also drives the rotating plate 9 to rotate together. The gravel falling above the rotating plate 9 moves along the inner wall of the cylinder body 5 under the action of centrifugal force and moves with the rotating plate 9 until it contacts the arc-shaped baffle 15 and is discharged from the discharge port I 14 under its block;

[0023] At the same time, during the rotation of the rotating plate 9, the round hole 92 provided thereon communicates with the corresponding sliding cylinder 83, so that the gravel in the sliding cylinder 83 falls to the bottom of the cylinder body 5. As the rotating plate 9 rotates, the sliding cylinder 83 also contacts the triangular block 91 at the corresponding position. The triangular block 91 is slidably matched with the notch 84, so that the triangular block 91 is inserted into the notch 84, and the sliding cylinder 83 moves upward along the inclined surface of the triangular block 91. The gravel in the sliding cylinder 83 moves upward along the inclined surface of the triangular block 91 together, thereby pushing the arc-shaped plate 82 upward, so that the arc-shaped plate 82 slides into the conical hole 102, pushing the slender particles stuck horizontally in the conical hole 102 into an inclined state and sliding down along the conical hole 102. At the same time, the arc-shaped plate 82 can also push the particles stuck in the conical hole 102 with a particle size larger than the minimum diameter of the conical hole 102 out of the conical hole 102 to avoid affecting the efficiency of the conical hole 102 in collecting slender particles. After the rotating plate 9 rotates until the triangular block 91 disengages from the sliding cylinder 83, the sliding cylinder 83 continues to closely adhere to the upper end of the rotating plate 9 under the action of gravity, and the two move relative to each other, so that the gravel in the sliding cylinder 83 passes through the round hole 92 and falls to the bottom of the cylinder body 5 to complete the screening work;

[0024] Two rolling cylinders are provided at the lower end of the base 1. When the tractor pushes the base 1 to move to the Figure 1 left side as shown, the gravel is compacted and leveled.
