Currently, most mainstream grading and screening equipment adopts a multi-level screen structure, using screens of different aperture sizes to achieve gradient grading of sand and gravel aggregates, meeting the differentiated needs of construction, infrastructure, and other fields for aggregates of different specifications.

[0003] In existing technologies, the connection between the screen and the storage bin in high-efficiency processing and grading equipment for sand and gravel aggregates mostly relies on traditional bolt fastening structures. To ensure stability during the screening process, some equipment has added auxiliary fixing components such as positioning pins and pressure strips. This results in the need to align the bolt holes one by one during installation, and the tightening process requires repeated adjustments of the force. The installation of a single screen takes a long time, and disassembling the screen also requires the use of tools such as wrenches, making the installation and disassembly of the screen quite inconvenient.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example 1: Reference Figures 1 to 5This is the first embodiment of the present invention, disclosing a high-efficiency processing and grading screening device for sand and gravel aggregates. It includes a vibrating screen body 1, a storage silo 2 fixedly connected to the top of the vibrating screen body 1, multiple screens 3 arranged inside the storage silo 2, a limiting component 6 between the storage silo 2 and the screens 3, and a discharge port 5 at the bottom of the storage silo 2. The limiting component 6 includes two sets of symmetrically arranged grooves 61 inside the storage silo 2, with sliders 62 slidably connected within the grooves 61. The outer ends of the sliders 62 are fixedly connected to the screens 3. A movable chamber 63 is fixedly connected to the left side of the storage silo 2. A first spring 64 is fixedly connected inside the 3-cell chamber. A rod 65 is slidably connected inside the movable chamber 63. One end of the rod 65 is in contact with the other end of the first spring 64. The other end of the rod 65 is connected to a slot 66 on the outer wall of the storage chamber 2 and the slider 62. The slot 66 is slidably connected to the rod 65. A guide groove 67 is provided on the front surface of the movable chamber 63. A connecting rod 68 is fixedly connected to the surface of the rod 65 in the guide groove 67. The connecting rod 68 is slidably connected to the guide groove 67. Two sets of limiting grooves 69 are provided on the inner wall of the guide groove 67. The limiting grooves 69 are rotatably connected to the connecting rod 68.

[0020] In use, firstly, the screen 3 drives the slider 62 to slide into the groove 61, aligning the insertion rod 65 with the slot 66 in the slider 62. Then, push and rotate the connecting rod 68 away from the screen 3, causing the connecting rod 68 to drive the insertion rod 65 to slide and rotate within the movable chamber 63 until the connecting rod 68 moves from one set of limiting grooves 69 into the guide groove 67. At this point, the restoring force of the first spring 64 pushes the insertion rod 65 to return to its original position within the movable chamber 63. When the connecting rod 68 moves to align with another set of limiting grooves 69, rotate the connecting rod 68 to enter the limiting groove 69, and then push the connecting rod 68 with the limiting groove 69 again using the restoring force of the first spring 64. When the inner wall abuts, the insertion rod 65 is inserted into the slot 66, thereby achieving the purpose of installing the screen 3. When it is necessary to disassemble the limiting component 6, the operation is reversed. The connecting rod 68 is cylindrical in design and has anti-slip texture on the outside, which can increase the contact area and friction between the connecting rod 68 and the worker's hand, thereby preventing the hand from slipping when using the connecting rod 68. The limiting groove 69 is L-shaped, and the inner wall of the limiting groove 69 fits against the surface of the connecting rod 68. The connecting rod 68 is rotated into the limiting groove 69, and then the restoring force of the first spring 64 pushes the connecting rod 68 to abut against the inner wall of the limiting groove 69, thereby achieving the purpose of installing the screen 3.

[0021] Example 2: Reference Figures 1 to 5This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a feed inlet 4 is provided at the top of the storage bin 2, a discharge outlet 5 is provided at the bottom of the storage bin 2, and a protective component 7 is provided outside the discharge outlet 5. The protective component 7 includes a fixing block 71 fixedly connected to the outer wall of the right side of the storage bin 2, a second spring 72 fixedly connected to the inner wall of the fixing block 71, a sliding rod 73 fixedly connected to the other end of the second spring 72, the sliding rod 73 being slidably connected to the fixing block 71, a threaded rod 74 fixedly connected to the bottom of the sliding rod 73, a threaded block 76 threadedly connected to the threaded rod 74, a protective cover 77 fixedly connected to the left side of the threaded block 76, and an annular scraper 78 fixedly connected to the top of the protective cover 77, the annular scraper 78 being slidably connected to the discharge outlet 5.

[0022] In use, first pull the slide bar 73 away from the discharge port 5, so that the slide bar 73 slides in the fixed block 71 and drives the second spring 72 to stretch. Then, the threaded block 76 rotates on the threaded rod 74, and the protective cover 77 and the annular scraper 78 rotate to align with the discharge port 5. Then, the restoring force of the second spring 72 drives the slide bar 73 to return to its original position and slide in the fixed block 71, and the threaded block 76 drives the protective cover 77 to block the bottom of the discharge port 5, thus achieving the purpose of protecting the discharge port 5. At the same time, the annular scraper 78 moves with the protective cover 77 and scrapes off the sand and gravel aggregates attached to the inner wall of the discharge port 5, thereby achieving the purpose of cleaning the discharge port 5. The cleaned sand and gravel aggregates will also be collected by the protective cover 77. A pull rod 75 is fixedly connected to the bottom surface of the threaded rod 74. The pull rod 75 has a round handle design, which makes it easy for the operator to pull the slide rod 73 so that the annular scraper 78 can slide out of the discharge port 5 for the operator to use. The protective cover 77 has a cavity inside and is transparent, which allows the protective cover 77 to collect the sand and gravel aggregate scraped off by the annular scraper 78. At the same time, the transparent protective cover 77 also makes it easy for the operator to observe and understand the amount of sand and gravel aggregate stored in the protective cover 77.

[0023] The remaining structure is the same as that in Example 1.
