[0016] Step 1: When in use, first input the pretreated mixed steel slag into the inner side of the mixed steel slag treatment box, at this time, the mixed steel slag is preliminarily screened by the guide frame arranged on the inner side of the mixed steel slag treatment box in cooperation with the sieve holes opened on its surface, and part of the screened mixed steel slag falls onto the upper surface of the first sieve plate and undergoes preliminarily screening through the first sieve plate, and then the preliminarily screened mixed steel slag falls onto the surface of the second sieve plate and undergoes further screening, while another part of the mixed steel slag passes through the crushing roller under the action of the guide frame, and at this time the second The operation of the motor causes the crushing roller connected to its output end to rotate, thereby crushing the mixed steel slag, and then the two screen plates are used to further screen the crushed steel slag. Since one side of the screen plate is connected to a suction pipe, and the suction pipe is controlled by an electromagnetic valve, the mixed steel slag of different sizes after screening can be drawn into the inner side of the suction pipe in batches according to actual usage requirements, and then the processed steel slag is input into the inner side of the preparation box through the delivery pipe under the action of the suction pump.

[0017] Step 2: Input the asphalt milling material to be processed into the inner side of the asphalt milling material processing cylinder through the opening at the top of the asphalt milling material processing cylinder. At this time, the third motor works so that the hollow shaft tube connected to its output end drives the connecting shaft to rotate accordingly. Under the rotation of the connecting shaft, the mixing rod will mix and stir the asphalt milling material. At the same time, the additive is input into the inner side of the connecting pipe through the feed inlet, and flows into the inner side of the hollow shaft tube through the connecting pipe, and then falls into the inner side of the material throwing net frame through the hollow shaft tube. At this time, the high-speed rotating material throwing net frame will throw the additive out through the through hole, so as to cooperate with the subsequent high-speed rotating mixing rod to fully mix the additive and the asphalt milling material. The processed asphalt milling material will be input into the inner side of the preparation box through the extraction pipe and the feed pipe arranged on the other side of the preparation box.

[0018] Step three: When all the materials used to prepare concrete are input into the inner side of the preparation box, the first motor works so that the driving gear connected to its output end drives the driven gear to rotate accordingly, and then the driven gear makes a circular motion along the gear ring, and the rotation of the driving gear drives the mounting frame to move through the rotating shaft, so as to realize the rotation of the scraper and the stirring blade, and at the same time, the rotation of the driven gear realizes the rotation of the spiral blade, and then cooperates with the rotating stirring blade to realize the full mixing and stirring of the materials, thereby improving the efficiency and effect of concrete preparation, and the overall practicality is higher.

[0021] 2. The mixed slag treatment box, the second motor, the screen plate, the crushing roller and other structures are provided to facilitate the subsequent crushing of the mixed slag, so that the slag of different sizes can be crushed into relatively small sizes, and then the slag that does not pass the size can be screened through the screen plate, which is convenient for the subsequent input of slag of different sizes into the interior of the preparation box according to actual preparation needs. The overall practicality is higher. When the slag is input into the inner side of the mixed slag treatment box, the guide frame can be used to cooperate with the holes opened on its surface to achieve preliminary screening of the slag, and then the second motor is used to realize the rotation of the crushing roller, so that the rotating crushing roller is used to cooperate with the convex block to realize the crushing of the slag, which is convenient for the subsequent crushing of the slag into smaller sizes;

[0022] 3. By setting up the asphalt milling material processing cylinder, mixing rod, heating plate and other mechanisms, the subsequent pretreatment of the asphalt milling material can be facilitated, and then the pretreated asphalt milling material is input into the inner side of the preparation box, so that it can be better mixed with mixed steel slag and other materials. When the asphalt milling material is input into the inner side of the asphalt milling material processing cylinder, the rotation of the mixing rod can be realized by the operation of the third motor. At the same time, the additive can be input into the throwing screen frame through the feed port, and thrown out by the high-speed rotating throwing screen frame, so that the additive can be better mixed with the asphalt milling material, thereby improving the efficiency of the pretreatment of the asphalt milling material and having higher overall practicality.

[0034] During operation, when the processed mixed slag material and asphalt milling material are input into the inner side of the preparation box 1, the first motor 4 works to rotate the driving gear 5 connected to its output end, and since the driving gear 5 and the driven gear 6 are meshed with each other through teeth, the rotation of the driving gear 5 can realize the movement of the driven gear 6, so that the driven gear 6 makes a circular motion along the meshing gear ring 7 on the other side thereof, and when the driving gear 5 rotates, the rotating shaft 8 drives the mounting frame 9 to rotate, and the rotating motion of the mounting frame 9 is realized. The connection rod 10 will drive the scraper 11 to rotate. Since the scraper 11 is attached to the inner wall of the preparation box 1, the material attached to the inner wall of the preparation box 1 can be effectively scraped off when the scraper 11 rotates. At the same time, the rotation of the rotating shaft 8 will cause the stirring blade 13 to rotate accordingly, and the rotation of the driven gear 6 will realize the rotation of the spiral blade 14. Then, the moving spiral blade 14 cooperates with the stirring blade 13 to achieve sufficient mixing and stirring of the material, thereby improving the preparation efficiency and effect of concrete, and the overall practicality is higher.

[0035] The crushing structure includes a feed port 15, a guide frame 16, a protrusion 17, a first screen plate 18, a second screen plate 19, a second motor 20 and a crushing roller 21. The feed port 15 is opened at one side of the top of the mixed steel slag processing box 2.

[0036] During operation, when the mixed steel slag is input into the inner cavity of the mixed steel slag treatment box 2 through the feed port 15, the mixed steel slag will pass through the guide frame 16, and the holes opened on the surface of the guide frame 16 can realize the preliminary screening of the mixed steel slag. The screened mixed steel slag falls onto the upper surface of the first screen plate 18, and is preliminarily screened through the sieve holes opened on the surface of the first screen plate 18. Then, the preliminarily screened mixed steel slag falls onto the surface of the second screen plate 19, and is further screened. Another part of the mixed steel slag will pass through the crushing roller 21 under the action of the guide frame 16. At this time, the second motor 20 works to rotate the crushing roller 21 connected to its output end. The mixed steel slag can be crushed by the rotation of the crushing roller 21 and the protrusions 17 set on the inner wall of the guide frame 16 and the mixed steel slag treatment box 2, and then the crushed steel slag can be further screened by the setting of the two screen plates.

[0037] A pumping pipe 22 is connected to the side wall of the mixed slag treatment box 2, and a pumping pump 23 is connected to the other end of the pumping pipe 22. The output end of the pumping pump 23 is connected to a delivery pipe 24, and the delivery pipe 24 penetrates the side wall of the preparation box 1 and extends to the inner side of the preparation box 1.

[0038] When working, the extraction pipe 22 is connected to the inner cavity of the mixed steel slag treatment box 2, and one side of the extraction pipe 22 is connected to multiple pipes, which are respectively connected to the inner cavity of the mixed steel slag treatment box 2 and controlled by an electromagnetic valve. Therefore, when the extraction pump 23 is working, the mixed steel slag of different sizes after screening in the mixed steel slag treatment box 2 can be extracted through the extraction pipe 22, and steel slag of different sizes can be extracted according to the needs of concrete preparation. Then, the steel slag extracted by the extraction pump 23 will be input into the delivery pipe 24, which is convenient for the subsequent input of the steel slag into the inner side of the preparation box 1 through the delivery pipe 24.

[0039] A third motor 25 is fixedly arranged at the middle of the top of the asphalt milling material processing cylinder 3, and a hollow shaft tube 26 is connected to the output end of the asphalt milling material processing cylinder 3, a connecting shaft 27 is connected to the bottom of the hollow shaft tube 26, and a mixing rod 28 is sleeved on the outer side of one end of the connecting shaft 27, and a material throwing net frame 29 is distributed below the mixing rod 28, and a through hole 30 is opened on the outer surface of the material throwing net frame 29;

[0040] During operation, when the asphalt milling material needs to be mixed and stirred, the third motor 25 works to rotate the hollow shaft tube 26 connected to its output end, and the hollow shaft tube 26 drives the connecting shaft 27 to rotate accordingly, and then the rotation of the connecting shaft 27 can realize the rotation of the mixing rod 28 and the material throwing frame 29, so that the asphalt milling material can be mixed and stirred by the rotating mixing rod 28, and the rotation of the material throwing frame 29 can disperse the additives through the through hole 30, so that the additives and the asphalt milling material can be fully mixed.

[0041] A feed inlet 31 is provided at one side of the top of the asphalt milling material processing cylinder 3, and a connecting pipe 32 is connected to the bottom of the feed inlet 31. A heating plate 33 is provided on the inner wall of the asphalt milling material processing cylinder 3.

[0042] During operation, when it is necessary to input the additive into the inner side of the asphalt milling material processing cylinder 3 for mixing with the asphalt milling material, the additive is input into the inner side of the connecting pipe 32 through the feed port 31. Since the connecting pipe 32 is connected to the hollow shaft tube 26, the additive can be input into the inner side of the hollow shaft tube 26 through the connecting pipe 32, and the additive is input into the material throwing net frame 29 through the hollow shaft tube 26, so as to facilitate the subsequent output of the additive. The setting of the heating plate 33 can perform high-temperature heating treatment on the asphalt milling material.

[0043] The driving gear 5 is meshed with the driven gear 6 through teeth, and the driven gear 6 is symmetrically distributed along the vertical center line of the driving gear 5;

[0044] When working, the operation of the first motor 4 will realize the rotation of the driving gear 5. Since the driving gear 5 and the driven gear 6 are meshingly connected, the rotation of the driving gear 5 will realize the rotation of the driven gear 6, thereby realizing the circular motion of the driven gear 6 along the gear ring 7.

[0045] The connecting rods 10 are equidistantly distributed along the center point of the mounting frame 9, and the connecting rods 10 and the mounting frame 9 are vertically distributed;

[0046] During operation, when the rotating shaft 8 rotates under the rotation action of the driving gear 5, the rotating shaft 8 will drive the mounting frame 9 to rotate accordingly. At this time, the rotation of the mounting frame 9 drives the connecting rod 10 to move synchronously, so as to facilitate the subsequent movement of the connecting rod 10 to drive the scraper 11 to scrape off the material attached to the inner wall of the preparation box 1, thereby preventing more material from being adsorbed on the inner wall of the preparation box 1.

[0047] The first sieve plate 18 and the second sieve plate 19 are distributed in a flat shape, and the size of the sieve holes opened on the surface of the first sieve plate 18 is larger than the sieve holes opened on the surface of the second sieve plate 19;

[0048] During operation, when the steel slag material falls onto the surface of the first screen plate 18, the sieve holes opened on the surface of the first screen plate 18 can be used to perform preliminary screening of the steel slag material, and then the screened steel slag material will fall onto the second screen plate 19, and then the second screen plate 19 will be used to perform secondary screening of the steel slag material, so that the steel slag material is screened into different sizes for separate stacking, and then the screened steel slag material is extracted in batches through the extraction pipe 22 controlled by the solenoid valve, so as to facilitate the subsequent preparation of better concrete.

[0049] The through holes 30 are evenly distributed along the center point of the material-discarding mesh frame 29, and the through holes 30 and the material-discarding mesh frame 29 form an integrated structure;

[0050] During operation, since the through holes 30 are equidistantly distributed along the center point of the material-throwing frame 29, when the material-throwing frame 29 rotates at high speed, the additives input into the inner side of the material-throwing frame 29 will be thrown out through the through holes 30, thereby achieving sufficient mixing between the subsequent additives and the asphalt milling material.

[0051] Specific working principle: first, when the mixed steel slag is input into the inner cavity of the mixed steel slag treatment box 2 through the feeding port 15, the mixed steel slag will pass through the provided guide frame 16, and the holes opened on the surface of the guide frame 16 can realize the preliminary screening of the mixed steel slag, and the screened mixed steel slag falls onto the upper surface of the first screen plate 18, and is preliminarily screened through the sieve holes opened on the surface of the first screen plate 18, and then the preliminarily screened mixed steel slag falls onto the surface of the second screen plate 19, and is further screened, while another part of the mixed steel slag will pass through the crushing roller 21 under the action of the guide frame 16, at this time, the second motor 20 works to rotate the crushing roller 21 connected to its output end, and the rotation of the crushing roller 21 and the guide frame 16 and the mixed steel slag treatment box 20 are utilized. The protrusion 17 arranged on the inner wall of the sorting box 2 can crush the mixed steel slag, and then the two sieve plates are arranged to further screen the crushed steel slag. Since the extraction pipe 22 is connected to the inner cavity of the mixed steel slag treatment box 2, and one side of the extraction pipe 22 is connected to multiple pipes, which are respectively connected to the inner cavity of the mixed steel slag treatment box 2 and controlled by an electromagnetic valve, when the extraction pump 23 is working, the mixed steel slag of different sizes after screening in the mixed steel slag treatment box 2 can be extracted through the extraction pipe 22, and steel slag of different sizes can be extracted according to the needs of concrete preparation. Then, the steel slag extracted by the extraction pump 23 will be input into the delivery pipe 24, which is convenient for the subsequent input of the steel slag through the delivery pipe 24. To the inner side of the preparation box 1, and when the asphalt milling material needs to be mixed and stirred, the third motor 25 works to rotate the hollow shaft tube 26 connected to its output end, and the hollow shaft tube 26 drives the connecting shaft 27 to rotate accordingly, and then the rotation of the connecting shaft 27 can realize the rotation of the mixing rod 28 and the throwing mesh frame 29, so that it is convenient to use the rotating mixing rod 28 to mix and stir the asphalt milling material, and it is convenient to fully mix the additive with the asphalt milling material. While mixing the asphalt milling material, the additive is input into the inner side of the connecting pipe 32 through the feeding port 31. Since the connecting pipe 32 is connected to the hollow shaft tube 26, the additive can be input into the inner side of the hollow shaft tube 26 through the connecting pipe 32, and through The hollow shaft tube 26 inputs the additive into the material-discharging mesh frame 29, and the rotation of the material-discharging mesh frame 29 can disperse and output the additive through the through hole 30, so as to facilitate the subsequent output of the additive and make it better mixed with the asphalt milling material. The setting of the heating plate 33 can perform high-temperature heating treatment on the asphalt milling material. When the treated mixed slag material and the asphalt milling material are input into the inner side of the preparation box 1, the first motor 4 works to rotate the driving gear 5 connected to its output end. Since the driving gear 5 and the driven gear 6 are meshed with each other through teeth, the rotation of the driving gear 5 can realize the movement of the driven gear 6, so that the driven gear 6 makes a circular motion along the meshing gear ring 7 on the other side.When the driving gear 5 rotates, the rotating shaft 8 drives the mounting frame 9 to rotate, and the connecting rod 10 drives the scraper 11 to rotate under the rotation of the mounting frame 9. Since the scraper 11 is attached to the inner wall of the preparation box 1, the material attached to the inner wall of the preparation box 1 can be effectively scraped off when the scraper 11 rotates. At the same time, the rotation of the rotating shaft 8 causes the stirring blade 13 to rotate, and the rotation of the driven gear 6 realizes the rotation of the spiral blade 14. Then, the moving spiral blade 14 cooperates with the stirring blade 13 to achieve full mixing and stirring of the materials, thereby improving the preparation efficiency and effect of concrete, and the overall practicality is higher.

10. A process for preparing a concrete preparation device for mixed steel slag and asphalt milling material, comprising a concrete preparation device for mixed steel slag and asphalt milling material according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: When in use, the pre-treated mixed steel slag is first input into the inner side of the mixed steel slag treatment box (2). At this time, the mixed steel slag is preliminarily screened by the guide frame (16) arranged inside the mixed steel slag treatment box (2) in conjunction with the sieve holes opened on its surface. Part of the screened mixed steel slag falls onto the upper surface of the first sieve plate (18) and undergoes preliminarily screening through the first sieve plate (18). Then, the preliminarily screened mixed steel slag falls onto the surface of the second sieve plate (19) and undergoes further screening. Another part of the mixed steel slag passes through the crushing roller (21) under the action of the guide frame (16). At this time, the second electric The machine (20) works so that the crushing roller (21) connected to its output end rotates accordingly, thereby crushing the mixed steel slag, and then using the two screen plates to further screen the crushed steel slag. Since one side of the screen plate is connected to a suction pipe (22), and the suction pipe (22) is controlled by a solenoid valve, the screened mixed steel slag of different sizes can be drawn into the inner side of the suction pipe (22) in batches according to actual usage requirements, and then the processed steel slag is input into the inner side of the preparation box (1) through the delivery pipe (24) under the action of the suction pump (23). Step 2: The asphalt milling material to be processed is input into the inner side of the asphalt milling material processing cylinder (3) through the opening at the top of the asphalt milling material processing cylinder (3). At this time, the third motor (25) works so that the hollow shaft tube (26) connected to its output end drives the connecting shaft (27) to rotate accordingly. Under the rotation of the connecting shaft (27), the mixing rod (28) mixes and stirs the asphalt milling material. At the same time, the additive is input into the inner side of the connecting tube (32) through the feed inlet (31) and passes through the connecting shaft (27). The additive is then poured into the asphalt milling material through the pipe (32) and into the inner side of the hollow shaft pipe (26). The additive is then poured into the inner side of the material throwing net frame (29) through the hollow shaft pipe (26). At this time, the high-speed rotating material throwing net frame (29) throws the additive out through the through hole (30), thereby cooperating with the subsequent high-speed rotating mixing rod (28) to fully mix the additive with the asphalt milling material. The processed asphalt milling material is then fed into the inner side of the preparation box (1) through the extraction pipe (22) and the delivery pipe (24) provided on the other side of the preparation box (1). Step 3: When all materials used for preparing concrete are input into the inner side of the preparation box (1), the first motor (4) works so that the driving gear (5) connected to its output end drives the driven gear (6) to rotate accordingly, and then the driven gear (6) performs a circular motion along the gear ring (7), and the rotation of the driving gear (5) drives the mounting frame (9) to move through the rotating shaft (8), thereby realizing the rotation of the scraper (11) and the stirring blade (13), and at the same time, the rotation of the driven gear (6) realizes the rotation of the spiral blade (14), and then cooperates with the rotating stirring blade (13) to achieve full mixing and stirring of the materials, thereby improving the efficiency and effect of concrete preparation, and the overall practicality is higher.
