[0019] In one embodiment of the present invention, the device for making concrete raw materials using waste fan blades is aimed at the problems raised in the prior art. In addition to the primary crushing component, an adjustable cutting component is provided. First, the material is put into the primary crushing chamber 1 through the feed port 1 2, and the material is squeezed and crushed by the primary crushing component. The material falls into the multi-stage screening component for layer-by-layer screening. The sieve holes of the multi-stage screening component are successively reduced from top to bottom. The adjustable cutting component is started according to the maximum sieve hole of the intercepted material (there may be material on sieve holes of different sizes, and the spacing of the blades 27 is determined by the maximum sieve hole of the intercepted material. The larger the sieve hole, the larger the spacing of the blades 27 is adjusted to avoid damaging the blades 27). The intercepted material is transferred to the upper side of the secondary crushing chamber 20 through the discharging component and the conveying component. The feed port 21 is provided with a guide plate 22. The material enters the secondary crushing chamber 20 under the action of the feed port 21 and the guide plate 22, and the material is cut and crushed for the second time by the adjustable cutting component, which not only ensures the crushing effect, but also avoids the problem of excessive material fragments damaging the blades 27.

[0023] In order to achieve layer-by-layer screening, a screen 1 9, a screen 2 10 and a screen 3 11 are provided (the number of screens and the screen holes can be selected and determined according to the needs, and in fact the number of screens can be more). The leaves after the initial crushing are screened layer by layer through the screen 1 9, the screen 2 10 and the screen 3 11. At the same time, the screen 1 9, the screen 2 10 and the screen 3 11 are respectively provided with a pressure sensor 17. After the screening is completed, according to the data change of the pressure sensor 17, it can be determined which layer of the screen intercepts the material, and the information is transmitted to the controller, and the controller is used to control the adjustable cutting component to adjust the spacing of the blades 27; In order to facilitate the discharge of materials, the screen 1 9, the screen 2 10 and the screen 3 11 can be set at an angle, so that the materials can be screened during the sliding process and can easily fall onto the conveying component through the discharge component.

[0025] A cavity is opened in the side wall of the primary crushing chamber 1, in which structures such as automatic telescopic rods can be arranged, and are connected to the movable door plate 16, which can drive the movable door plate 16 to perform lifting operations. When the screening is completed, the movable door plate 16 is controlled to rise, and the movable door plate 16 passes through the through slot 15, and the discharge port 12, the discharge port 2 13 and the discharge port 1 13 are opened, and the material in the primary crushing chamber 1 can fall onto the conveying assembly.

[0026] like Figure 1 and Figure 4 As shown, as a preferred embodiment of the present invention, the conveying assembly includes a plurality of transmission rollers 18, and a conveyor belt 19 is sleeved on the transmission rollers 18.

[0027] The number and position of the driving rollers 18 can be distributed according to the arrangement of the primary crushing chamber 1 and the feed port 2. The material falls onto the conveyor belt 19 through the discharge port 12, the discharge port 2 13 and the discharge port 3 14, and is then transmitted to the top of the feed port 2, enters the feed port 2 through the feed port 21, and is cut again by the adjustable cutting assembly.

The blades 27 installed on the two blade-adjustable rotating roller assemblies are staggered with each other.

[0029] After the spacing between the blades 27 is determined, the driving device three 23 is started, and the driving device three 23 drives the gear three 24 to rotate, thereby driving the gear three 24 and the gear four 25 to rotate relative to each other, thereby driving the two blade adjustable rotating roller assemblies to rotate, and the blades 27 staggered from each other on the two blade adjustable rotating roller assemblies can cut the material.

[0030] like Figure 5 As shown, as a preferred embodiment of the present invention, the blade adjustable rotating roller assembly comprises: A rotating roller 26, wherein a pitch changing platform 28 is installed in the rotating roller 26, and a fixing seat 29 is provided on the pitch changing platform 28; A mounting seat 30, mounted on the fixing seat 29, an automatic telescopic member 31 is mounted on the mounting seat 30, the automatic telescopic member 31 is electrically connected to the pressure sensor 17, and the automatic telescopic member 31 is controlled to contract based on information received by the pressure sensor 17; A compound lever structure 32 is installed in the pitch changing platform 28, a driving end of the compound lever structure 32 is slidably installed on a fixed seat 29, and an output end of the automatic telescopic member 31 is connected to the driving end of the compound lever structure 32; The tool collet 33 is connected to the telescopic structure of the composite lever structure 32 .

[0031] When the pressure sensor 17 detects that the debris is large, the automatic telescopic member 31 is activated to contract. The automatic telescopic member 31 applies a pulling force to the driving end of the compound lever structure 32, driving the driving ends of the compound lever structure 32 to close together, thereby driving the telescopic structure of the compound lever structure 32 to stretch. The telescopic structure of the compound lever structure 32 is composed of mutually connected force arms. When the driving ends are forced to close, the force arms can be gradually expanded. When the driving ends are forced to separate, the force arms can be gradually compressed. A tool collet 33 is installed on the hinge seat of the force arm. When the force arms are gradually expanded or compressed, the distance between adjacent tool collets 33 increases or decreases, thereby driving the adjustment of the distance between the blades 27. In order to improve the stability during the adjustment process, a slide groove 34 is provided at one end of the pitch change platform 28. During the deformation of the lever arm, the hinge seat slides in the slide groove 34. At the same time, a limit adjustment groove 35 is provided at the other end of the pitch change platform 28. The tool collet 33 is restricted in installation through the limit adjustment groove 35. The limit adjustment groove 35 is controlled to only move laterally to adjust the spacing without rotating, thereby achieving the purpose of adjusting the spacing of the blades 27.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
