[0002] Concrete is an artificial building material made of cement, sand, aggregate (such as gravel or crushed stone) and water in a certain proportion. Concrete is in a slurry state during construction, and will gradually harden into a solid stone-like body after a certain period of time. It is widely used in construction projects to build various building structures such as houses, bridges, roads, tunnels, dams, etc. Concrete has the advantages of strong durability, high compressive strength and convenient construction, so it is widely used.

[0003] According to a Chinese patent publication numbered CN220371607U, a concrete production raw material screening device is disclosed, which includes a material collection box, a screening plate, a linear drive unit, a scraping structure and a collective unloading structure; the scraping structure can screen out stones larger than the standard particles and push them out while meeting the permeability of the standard particle stones, and in the process of pushing the stones, the standard particle stones can be promoted to be screened and unloaded through the screening plate, so the quality and efficiency of stone screening can be improved while reducing the difficulty of stone loading; the collective unloading structure can perform unidirectional transmission of the standard particle stones unloaded through the screening plate to the material collection box, so as to concentrate the position of the unloading stones, and facilitate the packaging and collection of stones while avoiding blockage caused by stone accumulation;

[0004] The above cited patent still has certain shortcomings in actual use. The screening plate used for screening is fixedly installed on the top of the material receiving box. When the screening plate needs to be replaced and repaired, the disassembly becomes very cumbersome and requires a lot of manpower, which affects the progress of the construction. Therefore, a raw material screening device for concrete production and processing is proposed to solve the above problems. Utility Model Content

[0030] In this embodiment, the two side limit blocks 26 each have a rectangular cavity and an opening on one side.

[0031] Specifically, refer to Figure 3-4 The outer ends of the two sliding blocks 22 are each equipped with a positioning block 221, and the two positioning blocks 221 are respectively engaged with the cavity in the side limit block 26 on one side.

[0032] In this embodiment, a positioning block 221 is installed at one end of the sliding block 22 , and a size of the positioning block 221 matches an opening on one side of the side limiting block 26 .
