In an embodiment of the present invention: A sorting belt conveyor for various civil engineering materials includes a conveyor belt component 4 for conveying sands and gravels of various sizes. A sorting cover structure 3 is respectively arranged on both sides of the conveyor belt component 4. The sorting cover structure 3 is used to sort sands and gravels of various sizes during the synchronous conveying process in cooperation with the conveyor belt component 4;

[0046] It should be noted that the hydraulic telescopic rod is a prior art, which can be directly purchased on the market, or purchased parts for assembly. At the same time, it can also be replaced with a hydraulic telescopic rod, or replaced with an electric telescopic rod, etc. There is no limitation on which structure to choose, as long as it can meet the requirement of adjusting the inclination height of the main unit conveyor belt 44 through its own telescopic adjustment. Here, a hydraulic telescopic rod is preferably used.

[0060] The side mounting plates 11 are perpendicularly distributed to the horizontal fixing plate 12, and the side mounting plates 11 are distributed above the sorting cover structure 3;

[0061] Reinforcing plate members 13 are installed on the side mounting plates 11. The reinforcing plate members 13 are composed of a reinforcing plate and multiple bolts (the multiple bolts are inserted through the reinforcing plate and are fixed on the side mounting plates 11); a support plate 14 is fixed on the reinforcing plate members 13, and one end of the support plate 14 far from the reinforcing plate members 13 is fixed on the outer feeding component 2 (specifically, one end of the support plate 14 far from the reinforcing plate members 13 is fixed on the bottom support plate 22).

[0062] Specific reference is made to Figure 2 and Figure 3In the embodiment of the present invention: the side mounting plate 11 is provided with a plurality of auxiliary material-selecting structures 15 on the side close to the sorting cover structure 3;

[0063] The auxiliary material-pickup structure 15 includes an inner support wheel 153, and a plurality of auxiliary material-pickup plates 152 distributed in an inclined array are fixed to the outside of the inner support wheel 153. The auxiliary material-pickup plates 152 are used to assist in accelerating the sorting cover structure 3 forward to sort sand and gravel of various sizes and to clean and sort the sand and gravel on the sorting cover structure 3. The edges of the auxiliary material-pickup plates 152 at one end away from the inner support wheel 153 are arranged in an inclined shape to fit the sorting cover structure 3.

[0064] A fixing column 154 is fixed on the center line of the column of the inner supporting wheel 153 , and both ends of the fixing column 154 are fixed on a U-shaped fixing shell 151 , and the fixing shell 151 is installed on the side mounting plate 11 .

[0065] It can be seen that after the external material shifting component 2 is started, it shifts materials from multiple positions on the conveyor belt component 4 to the sorting cover structure 3 at multiple points, and uses the sorting cover structure 3 to sort sand and gravel of various sizes. At the same time, the auxiliary material shifting component 1 uses the multiple auxiliary material shifting plates 152 distributed in an inclined array on the auxiliary material shifting structure 15 to achieve the auxiliary material shifting plates 152 to assist in forward acceleration of the sorting cover structure 3 to sort sand and gravel of various sizes and clean and shift the sorting cover structure 3.

[0066] It should be noted that the auxiliary material-selecting structure 15 is driven by an electric motor, which can be purchased directly on the market, or parts can be purchased and assembled. There are also relevant descriptions in corresponding journals. It is not what the present invention wants to protect and will not be elaborated here.

[0067] The working principle of the present invention is:

5. The multi-type civil engineering material sorting belt conveyor according to claim 1, characterized in that The auxiliary feeding component (1) is composed of a transverse fixing plate (12) and two side erection plates (11) fixed at both ends of the transverse fixing plate (12). The side erection plates (11) are vertically distributed with the transverse fixing plate (12), and the side erection plates (11) are distributed on the upper side of the sorting hood structure (3). Reinforcing plate members (13) are installed on the side erection plates (11). The reinforcing plate members (13) are composed of a reinforcing plate and a plurality of bolts. A support plate (14) is fixed on the reinforcing plate members (13), and the support plate (14) is fixed on the outer feeding component (2) at the end far from the reinforcing plate members (13).

6. The multi-type civil engineering material sorting belt conveyor according to claim 5, characterized in that A plurality of auxiliary feeding structures (15) are installed on the side erection plates (11) on the side close to the sorting hood structure (3). The auxiliary material-shifting structure (15) includes an inner support wheel (153), and a plurality of auxiliary material-shifting plates (152) arranged in an inclined array are fixed outside the inner support wheel (153). The auxiliary material-shifting plates (152) are used to assist in accelerating the sorting cover structure (3) forward to sort sand and gravel of various sizes and to clean and shift the sorting cover structure (3) after sorting. The edges of the auxiliary material-shifting plates (152) at one end away from the inner support wheel (153) are arranged in an inclined shape so as to fit the sorting cover structure (3). A fixing column (154) is fixed on the column center line of the inner supporting wheel (153), and both ends of the fixing column (154) are fixed on a U-shaped fixing shell (151), and the fixing shell (151) is installed on the side mounting plate (11).
