Technical Field

[0001] The utility model relates to the technical field of removing large particles of cemented sand and gravel, in particular to a device for efficiently removing large particles of cemented sand and gravel at the foot of a slope during an inclined layer rolling operation. Background Art

[0002] "Cemented gravel" refers to a building material that uses cement or other cementing materials to bond granular materials such as sand and gravel together. This material is usually used in projects such as roads, bridges, and building foundations and pavements to enhance the stability and bearing capacity of the structure. In construction projects, cemented gravel is widely used. Cemented gravel can be prepared by selecting different types and proportions of cementing materials and granular materials according to specific project requirements. Before use, by removing oversized stones, the use of materials that do not meet the design requirements during the construction process is reduced.

[0003] With regard to the existing related technologies, the inventors believe that the following defects often exist: when the device is removing large particles, some of the particles will get stuck in the mesh of the removal net. When used for a long time, most of the mesh of the removal net will be blocked by particles, which will reduce the effect of the device in removing large particles. Originally, it only took one time to remove the large particles, but now because the mesh is blocked, it takes multiple times to remove the large particles completely. Utility Model Content

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a high-efficiency removal device for large particles at the foot of a slope when a cemented sand and gravel is rolled in an inclined layer. The high-efficiency removal device for large particles at the foot of a slope when a cemented sand and gravel is rolled in an inclined layer comprises a frame 1, a screen cylinder 2 is rotatably mounted on the frame 1, a top plate 3 is welded on the top of the frame 1, a buffer barrel 4 is mounted on the side of the top plate 3, a material balancing structure 6 is mounted on the right side of the frame 1, a material receiving port of the material balancing structure 6 is located directly below the discharge port of the buffer barrel 4, and a clearing structure 5 is mounted on the top plate 3;

[0028] The clearing structure 5 includes two T-shaped guide rods 51 slidably installed on both sides of the top of the top plate 3, and sliding holes for the T-shaped guide rods 51 to slide are opened on both sides of the top of the T-shaped guide rods 51. An upgrade plate 52 is welded between the bottom ends of the two T-shaped guide rods 51, and the upgrade plate 52 can be raised and lowered in a controllable manner. A row of rubber blocks 53 are installed at the bottom of the upgrade plate 52. The rubber blocks 53 play a buffering role and buffer the impact force when the top block 54 contacts the granular material. The top block 54 is installed at the bottom of the rubber block 53.

[0029] An arc-shaped cavity is provided on both sides of the frame 1, and five limiting tugboats 7 are installed at equal intervals on the inner wall of the arc-shaped cavity. Extension pipes 8 are welded at both ends of the screen cylinder 2. The outer wall of the extension pipe 8 is sleeved with a limiting ring 9. The limiting tugboats 7 limit the position of the limiting ring 9 to prevent the screen cylinder 2 from shifting in position during rotation, thereby ensuring the stability of the rotation state of the screen cylinder 2.

[0030] The pellets are continuously conveyed to the interior of the buffer barrel 4, and the pellets fall from the discharge end of the buffer barrel 4 and are collected by the collecting bin 67. Then, the pellets enter the interior of the distribution pipe 65 and are guided into the interior of the screen cylinder 2 through the distribution pipe 65. The screen cylinder 2 is placed in a tilted downward state, and the pellets fall at the high point inside the screen cylinder 2, and the pellets roll downward. Small-diameter pellets fall directly through the mesh on the screen cylinder 2, and large-diameter pellets are discharged from the left end of the screen cylinder 2. The servo motor A drives the gear A to rotate, and the meshing transmission action of the gear A and the annular rack 10 drives the screen cylinder 2 to rotate. When the screen cylinder 2 rotates, the pellets are in a rolling state inside the screen cylinder 2, which is beneficial to accelerate the falling speed of the pellets inside the screen cylinder 2, so as to increase the speed of removing the pellets. At the same time, the screen cylinder 2 is in a rotating state, which expands the contact area between the pellets and the screen cylinder 2, and more comprehensively utilizes the mesh on the screen cylinder 2, which also helps to improve the efficiency of removing the pellets.

[0031] An annular rack 10 is sleeved outwardly of the right extension tube 8 , a servo motor A is installed on the right side of the bottom of the top plate 3 , and a gear A meshing with the annular rack 10 is installed at the driving end of the servo motor A.

[0032] The clearing structure 5 also includes a motor frame 58 installed at the bottom of the top plate 3, a servo motor B is installed inside the motor frame 58, a rotating plate 57 is provided at the driving end of the servo motor B, a rotating shaft B59 is installed at the outer edge of the front side of the rotating plate 57, a rotating shaft A55 is rotatably installed in the middle of the top of the upgrade plate 52 through a bearing, and a push-pull plate 56 is rotatably installed between the rotating shaft A55 and the rotating shaft B59.

[0033] During use, the servo motor A drives the screen cylinder 2 to rotate, and the mesh of the screen cylinder 2 is moved to just below the top block 54. At the same time, the servo motor B drives the rotating plate 57 to rotate. Under the linkage action of the rotating shaft A55, the push-pull plate 56 and the rotating shaft B59, and under the guiding action of the two T-shaped guide rods 51 on the upgrading plate 52, one rotation of the rotating plate 57 can drive the upgrading plate 52 to move downward and then reset. When the upgrading plate 52 moves downward, the top block 54 will enter the mesh of the screen cylinder 2. If there is granular material stuck in the mesh of the screen cylinder 2, the top block 54 will directly push the granular material downward to clean the granular material stuck in the mesh of the screen cylinder 2. The screen cylinder 2 rotates 360 degrees, and the rubber block 53 cleans each mesh on the screen cylinder 2, which can prevent the granular material from blocking the mesh of the screen cylinder 2 and affecting the removal efficiency.

[0034] Example 2

[0035] Reference Figure 1-2 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0036] The material distribution structure 6 includes a U-shaped frame 61 welded to the right side of the frame 1, and a distribution pipe 65 is arranged on the U-shaped frame 61. A collection bin 67 is welded to the feeding end on the right side of the distribution pipe 65. The setting of the collection bin 67 can catch the pellets falling from the buffer barrel 4 even if the distribution pipe 65 drives the collection bin 67 to swing.

[0037] A gear B66 is sleeved on the transverse tube of the distribution pipe 65, a pad 62 is welded inside the U-shaped frame 61, a driving motor 63 is installed on the top of the pad 62, and a spur rack 64 meshing with the gear B66 is installed on the driving end of the driving motor 63. Under the meshing transmission action of the spur rack 64 and the gear B66, the distribution pipe 65 is in forward and reverse rotation, which will realize that the discharge end of the distribution pipe 65 is in a reciprocating swing state. The swinging discharge of the distribution pipe 65 will expand the area where the distribution pipe 65 falls inside the screen cylinder 2, avoiding the distribution pipe 65 discharge from the material concentration at a certain point inside the screen cylinder 2, which helps to improve the filtration rate of the granular material.

[0038] Circular holes are provided on both sides of the U-shaped frame 61 for the material distribution pipe 65 to pass through, and bearings are installed inside the circular holes. At the same time, the material distribution pipe 65 is rotatably installed between the two bearings.

[0039] During use, when the granular material passes through the inside of the distribution tube 65, the spur rack 64 is driven upward or downward by the extension and contraction of the drive motor 63, and the distribution tube 65 is rotated in the forward and reverse directions under the meshing transmission action of the spur rack 64 and the gear B66, so that the discharge end of the distribution tube 65 is in a reciprocating swinging state, and the swinging discharge of the distribution tube 65 will expand the area where the distribution tube 65 falls inside the screen cylinder 2.

[0040] The remaining structures are the same as those of Example 1.
