DETAILED DESCRIPTION

[0015] The utility model will be further explained in detail in combination with the drawings and specific embodiments.

[0016] EMBODIMENT

[0017] As shown in Figure 1 and Figure 2 The automatic coated sand turning, breaking and collecting system provided by the embodiment comprises a rack 1, the bottom of the rack 1 is paved with a rolling roller for conveying, one side of the bottom of the rack 1 is provided with a feeding channel 2, the end of the feeding channel 2 is flush with the surface of the rolling roller, when the sand core protecting tube is poured, the sand core protecting tube is conveyed to the surface of the rolling roller at the bottom of the rack 1 through the feeding channel 2;

[0018] The rack 1 top is provided with a sliding assembly 3, which comprises a chain wheel and a sliding chain plate, that is, the chain wheel is fixedly installed on the top of the rack 1, the sliding chain plate is engaged with the chain wheel, and the chain wheel is connected with a driving mechanism 5. In the embodiment, the driving mechanism 5 adopts a driving motor. The end of the sliding chain plate away from the chain wheel is fixedly provided with a sliding support seat 4 at the bottom. Through the operation of the driving motor, the chain wheel is driven to rotate, so that the sliding chain plate is displaced reciprocatingly along the length direction of the rack 1 on the top of the rack 1, that is, the sliding support seat 4 is reciprocatingly slid along the length direction of the rack 1 on the top of the rack 1.

[0019] The bottom of the sliding support seat 4 is symmetrically provided with vertical guide rails 6. The lifting seats are installed in sliding fit with the vertical guide rails 6, and lifting motors are installed on the lifting seats to control the lifting thereof. That is, the lifting seats on the two vertical guide rails 6 are synchronously lifted through the lifting motors.

[0020] The lifting seats are installed with a mechanical hand 7 to drive the driving mechanism 5, and a rotating shaft is installed on one side of the middle part of the principle mechanical hand 7. The other end of the rotating shaft penetrates through the lifting seat and is connected with a turnover motor 8.

[0021] That is, the sliding assembly 3 driven by the driving mechanism 5 can make the sliding support seat 4 translate to above the rack 1 at the end of the feeding channel 2, that is, above the sand core bushing fed through the feeding channel 2. At this time, the mechanical hand 7 is controlled to descend to the sand core bushing through the lifting motor, and the mechanical hand 7 is driven to work to clamp the sand core bushing through the driving mechanism 5 of the mechanical hand 7. After clamping, the mechanical hand 7 is controlled to ascend by the lifting motor, and is translated back to the initial position.

[0022] The bottom of the rack 1 is also provided with a vibrating core knockout machine 9 near the end of the feeding channel 2. That is, the initial position of the mechanical hand 7 is directly above the vibrating core knockout machine 9. When the mechanical hand 7 clamps the sand core bushing to return to above the vibrating core knockout machine 9, the turnover motor 8 is operated to drive the sand core bushing to turn over 180°, so that the products and sand cores poured in the sand core bushing fall into the vibrating core knockout machine 9, thereby completing the turnover work.

[0023] Through the vibration of the vibrating core knockout machine 9 and the separation of the filter screen, the waste sand and the bolts and nuts in the waste sand vibrated and broken are discharged from the bottom discharge port through the filter screen, and the products fall above the filter screen and are taken out through one side of the vibrating core knockout machine 9.

[0024] The lower side of the vibrating core knockout machine 9 is provided with a conveying belt 10, and a material collecting frame 11 is fixedly installed on the conveying belt 10. The material collecting frame 11 is located directly below the discharge port of the vibrating core knockout machine 9.

[0025] The waste sand, bolts and nuts discharged from the bottom of the vibrating core knockout machine 9 fall into the material collecting frame 11, and are conveyed through the conveying belt 10 after collecting the waste sand, bolts and nuts of one sand core bushing.

[0026] The magnetic separator 12 is arranged on the first conveying belt 10, the magnetic attraction part of the magnetic separator 12 faces the surface of the first conveying belt 10, and the spacing between the magnetic attraction part of the magnetic separator 12 and the surface of the first conveying belt 10 is matched with the height of the collecting frame 11; the collecting frame 11 is conveyed through the first conveying belt 10 and passes below the magnetic separator 12, when the collecting frame 11 passes below the magnetic separator 12, the strong magnetic force of the magnetic separator 12 attracts the metal in the collecting frame 11, that is, the bolts and nuts are attracted out, so that only waste sand is left in the collecting frame 11;

[0027] The crusher 13 is arranged below the end of the first conveying belt 10, and the feeding hopper of the crusher 13 is located directly below the end of the first conveying belt 10; when the collecting frame 11 is conveyed to the end of the first conveying belt 10, the collecting frame 11 is overturned with the first conveying belt 10, so that the waste sand in the collecting frame 11 is poured out, and since the feeding hopper of the crusher 13 is located directly below the first conveying belt 10, the poured waste sand falls into the feeding hopper of the crusher 13, so that the waste sand is crushed once in the crusher 13;

[0028] The second conveying belt 14 is arranged at the discharge port of the crusher 13, and the secondary crushing device 15 is installed at the end of the second conveying belt 14; that is, the waste sand crushed once is conveyed to the secondary crushing device 15 through the second conveying belt 14 to be crushed twice; in the embodiment, the upper part of the secondary crushing device 15 is a crusher 13, and the lower part is a crushing mechanism, so that the waste sand treated by the secondary crushing device 15 is in the form of gravel;

[0029] The discharge end of the secondary crushing device 15 is connected with the feeding port of the sand elevator 16, and the discharge port of the sand elevator 16 is connected with the sand tank 17; that is, the waste sand in the form of gravel is conveyed into the sand tank 17 through the sand elevator 16 to be stored, when the waste sand in the sand tank 17 reaches a certain amount, the bottom electromagnetic pull brake is opened, and the waste sand is transported to the heat treatment workshop by a transport vehicle to be heat treated to remove chemical substances such as resin, so that the whole waste sand regeneration process is completed.

[0030] The above only describes the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, any modification and replacement based on the technical solutions and the application concept provided by the present application should be covered in the protection scope of the present application.
