[0002] Sand screening machines are widely used in construction and building materials sites. Sand and gravel are needed for pouring and construction in the construction industry, but some molding sands may clump or be mixed with other impurities due to their own reasons. Therefore, the sand and gravel need to be filtered before use to remove impurities. However, most of the sand screening machines on the market today have inconveniences in loading and unloading residual impurities when screening sand and gravel, and the efficiency is low due to the small amount of sand screened. Therefore, a more convenient sand screening machine is needed.

[0003] The defects of a sand screening machine in the prior art are: Patent document CN209935184U discloses a sand screening machine, which relates to the technical field of sand and gravel separation. "It includes a base, a coarse sand cylinder arranged above the base, a driving plate is arranged at one end of the coarse sand cylinder, and a rotating plate rotatably connected to the base is arranged at the other end, and a vertical driving assembly is arranged on the base. Both ends of the coarse sand cylinder are fixedly connected to driving frames rotatably connected to the driving plate and the rotating plate respectively, and a rotating driving assembly connected to the driving frame is arranged on the driving plate. The outer periphery of the coarse sand cylinder is fixedly connected to a fine sand cylinder, and a plurality of sieve holes are opened through the peripheral walls of the coarse sand cylinder and the fine sand cylinder, and the sieve holes on the coarse sand cylinder are larger than the sieve holes on the fine sand cylinder. A cylindrical material guide cylinder is arranged at one end of the coarse sand cylinder close to the rotating plate, and the material guide cylinder extends out of the end of the fine sand cylinder close to the rotating plate, and a connecting frame is fixedly connected between the rotating plate and the movable plate, and a telescopic rod is movably arranged between each connecting frame and the base. The utility model has the effect of separating multiple impurities at one time."

[0004] However, although the above device can screen sand when in use, it needs to be folded and placed horizontally after the sand is loaded, so as to be connected to the rotating device part to achieve the effect of rotating screening. Due to the horizontal placement, the device cannot screen more sand and gravel at one time, and if there is a lot of sand and gravel, it will cause the sand and gravel to pour out from the sand loading place when it is placed horizontally and connected to the sand screening part of the sand screening machine, so the device will result in a small amount of sand without screening, which reduces the sand screening efficiency of the device. Therefore, the equipment still has certain shortcomings and needs further improvement. Utility Model Content
