[0002] Mining machine-made sand is a kind of artificial sand made by machine grinding and screening ore or rock. The processing of mining machine-made sand mainly includes the following steps: mining, crushing, grinding, screening, sand washing and drying. Through the above steps, mining machine-made sand can obtain high-quality artificial sand, which is widely used in construction, railways, water conservancy projects and concrete mixing plants.
[0003] Existing related technologies often have the following defects: At present, in the production process of aggregate mine artificial sand, when the fine sand recovery machine recovers fine-particle artificial sand with a particle size of 0.075mm-2.36mm, the fine particles still contain about 15% moisture after dehydration by the dewatering screen. The fine-particle artificial sand will "clump" and is not easy to loosen by itself, resulting in insufficient mixing of fine sand and coarse sand. After being transported to the yard by the conveying system, the gradation of the finished artificial sand is unstable and the quality is abnormal.
[0004] The problem of fine-grained water-washed sand "clumping" has been effectively solved.
[0005] Therefore, the utility model provides a new type of fixture for solving the "clumping" phenomenon of fine-grained water-washed machine-made sand. Utility Model Content

[0030] Reference Figure 1-6 As shown, the utility model provides a technical solution: a new type of fixture for solving the "clumping" phenomenon of fine-grained water-washed machine-made sand, comprising a metal cage 3 and two mounting blocks 1.
[0031] The following is a detailed description of its overall specific settings and functions.
[0032] In this embodiment, both mounting blocks 1 are provided with hanging slots 5. A metal cage 3 is welded from several φ20 round steel bars. A shaft 2 is mounted inside the cage 3, with both ends of the shaft 2 shaped square. The hanging slots 5 are sized to match the ends of the shaft 2, and two bearings 4 are installed between the shaft 2 and the cage 3. The force applied to the scrambler during the conveying of machine-made sand drives the scrambler to rotate along its central axis. The protruding portions at both ends are square and can be placed directly into the hanging slots 5, facilitating assembly and disassembly.
[0033] Specifically, a limit ring 6 is placed on the outside of the metal cage 3. Several rubber limit frames 9 are evenly and securely attached to the inside of the limit ring 6. Several rows of bristles 10 are fixedly attached to the inside of the limit frames 9. The inner sides of the rows of bristles 10 form a circular ring structure. The bristles 10 arranged in a circular ring structure can clean dust from the outside of the metal cage 3.
[0034] Two limit frames 11 are slidably connected to the interior of the limit ring 6. One side of each limit frame 11 is grooved. These two limit frames 11 rest against the surfaces of two opposing round steel bars on the metal cage 3, thereby enhancing the stability of subsequent movement of the limit ring 6. Several steel balls 12 are evenly secured to the inner sides of the limit frames 11. The presence of these steel balls 12 reduces friction between the limit frames 11 and the round steel bars during movement of the limit ring 6.
[0035] The internal thread of the limiting ring 6 is connected to a driving rod 13, and the driving rod 13 is rotatably connected to the inside of the limiting frame 11. When the driving rod 13 is rotated, the driving rod 13 will push the limiting frame 11 to move. The outer side of the limiting ring 6 is fixedly connected to a handle 7, and the side wall of the handle 7 is evenly glued with a number of anti-slip pads 8. The provision of the anti-slip pads 8 increases the friction when the hand holds the handle 7, and improves the stability of operating the handle 7. The side wall of the limiting ring 6 is fixedly connected to a mounting plate 14, and the inner side of the mounting plate 14 is covered with a hook 15. By hooking the mounting plate 14 on the surface of the hook 15, the limiting ring 6 can be temporarily hooked.
[0036] Working principle: In the present invention, the intermediate shaft 2 of the scatterer is made of φ20 round steel, and a ball bearing 4 is installed at each end of the round steel. A square structure is extended from the inner hole of the bearing 4 at both ends of the round steel. The outer diameter of the scatterer is 500mm and is arranged around the circumference with a spacing of 10cm by φ12 steel bars. The scatterer is installed to the conveying system leader. The force thrown onto the scatterer during the conveying process of the machine-made sand drives the scatterer to rotate along the central axis. The protruding parts at both ends are square and can be directly placed in the hanging groove 5 for easy disassembly and assembly. When the machine-made sand passes through the scatterer, it is scatter The device rotates to break up the fine particles of washed sand, thereby achieving the stability of the particle gradation of machine-made sand and ensuring that the quality of machine-made sand meets the standards. The hook 15 is welded to the inner side of the equipment, and the mounting plate 14 is hooked on the surface of the hook 15 to achieve temporary hooking of the limit ring 6. When there is a lot of dust and other impurities adhering to the outside of the metal cage 3, the mounting plate 14 on the hook 15 is taken out, and the limit ring 6 is moved to the outside of the metal cage 3. At this time, the driving rod 13 is rotated, and the driving rod 13 will push the limit frame 11 to move. The two limit frames 11 can be attached to the other parts of the metal cage 3. The surfaces of the two relative round steels are arranged in the middle, thereby improving the stability of the subsequent movement of the limit ring 6. After the rubber limit frame 9 is put on the outside of the round steel, the limit ring 6 can be moved by holding the handle 7. The setting of the steel ball 12 reduces the friction between the limit frame 11 and the round steel during the movement of the limit ring 6, thereby improving the pushing efficiency of the limit ring 6. In the process of moving the limit ring 6, the bristles 10 arranged in a circular ring structure can realize the cleaning of the dust on the outside of the metal cage 3. In the process of holding the handle 7, the setting of the anti-slip pad 8 increases the hand holding the handle The friction force when holding 7 improves the stability of operating the handle 7. By cleaning the round steel surface on the outer side of the metal cage 3, the metal cage 3 is kept clean, and the effect of breaking up the clumping washed sand by the practical metal cage 3 is improved to a certain extent. The utility model designs a new combination mechanism and realizes the stability of the particle gradation of machine-made sand and the improvement of quality in a specific field. The advantages of the utility model are: reducing the "clumping" phenomenon of fine-grained washed machine-made sand; improving the uniform distribution of fine-grained machine-made sand; ensuring the stability of the particle gradation of machine-made sand and improving the quality of machine-made sand.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
