Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing devices, in particular to a concrete sand and gravel separator. Background Art

[0002] Concrete sand and gravel separator is a kind of equipment specially used to separate sand and gravel from concrete. It is mainly composed of feed port, screen, vibrator and discharge port. When working, concrete is first poured into the feed port and then distributed onto the screen. The screen starts to vibrate. The frequency and amplitude can be adjusted to adapt to sand and gravel particles of different sizes. As the screen vibrates, the sand and gravel particles in the concrete gradually fall down, and at the same time roll and collide with each other in the holes of the screen. Due to the different characteristics of sand and gravel particles such as viscosity and weight, they will gradually be separated during the screening process.

[0003] After searching, in the prior art, a Chinese patent (publication number CN219943521U) discloses a concrete sand and gravel separator, including a bracket and a discharge bin. The bracket is provided with a motor, a spiral and a sand barrel, the spiral is connected to the motor, the spiral is located inside the sand barrel, the discharge bin is located below the sand barrel, the two sides of the discharge bin are installed at the lower end of the bracket through a fixing member, and a movable member is provided in the middle of the fixing member. The discharge bin moves from bottom to top to keep the movable member from rotating upward under force, and the discharge bin can be placed on the movable member and restricted at the fixing member. The concrete sand and gravel separator realizes that the discharge bin can be stably installed at the lower end of the bracket through the cooperation of the fixing member and the movable member, and can ensure that the discharge bin can be fixed without bolts, which is convenient for the installation and disassembly of the discharge bin, and also convenient for the later cleaning of the inside of the sand barrel, but there are still the following deficiencies.

[0004] The discharge bin of the existing sand and gravel separator can be quickly installed or disassembled through the cooperation of the fixing parts and movable parts on both sides, which improves the disassembly and assembly cycle of the discharge bin. However, since the discharge bin of the separator is usually made of metal materials, the discharge bin is heavy, and the above-mentioned discharge bin lacks a supporting structure. As a result, after the discharge bin is disassembled, it needs to be manually lifted to ensure that the discharge bin can be stably taken out from the inside of the separator, which leads to high labor intensity for the workers. Therefore, the inventor proposes a concrete sand and gravel separator to solve the above problems. Utility Model Content
