[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The excavator guard plate casting discharging device is provided with a rotating mechanism and a second cleaning mechanism, etc., so that the guard plate casting after sand casting is conveyed along with the sand casting mold on the first conveyor belt. When it is conveyed to one side of the push plate, the cylinder is started, and the sand casting mold is pushed to the second conveyor belt through the push plate for conveying. When the sand casting mold abuts against the baffle plate, it is blocked. Then, the first moving block is driven to move by the first moving module, and at the same time, the second moving block is driven to rise and fall by the second moving module, so that the electromagnet can be moved to the top of the upper mold. Then, the electromagnet is energized, and at this time, the upper mold can be adsorbed. At the same time, the molding sand in the upper mold can fall on the second conveyor belt for transportation, and when it is moved to the top of the second conveyor belt, the electromagnet is powered off, so that the upper mold can be placed on the second conveyor belt. Then, the guard plate casting in the sand casting mold can be adsorbed by the electromagnet and placed on the second conveyor belt. Then, the second motor is started. When the second motor rotates, the rotating plate is driven to rotate through the rotating shaft, thereby driving the electromagnet to rotate and rotate 90 degrees to a vertical state. Then, the side wall of the lower mold is adsorbed by the electromagnet, and then the second motor is started to reverse and the electromagnet is rotated 180 degrees in the opposite direction, thereby driving the lower mold to flip 180 degrees. It is turned over so that the molding sand inside it falls on the second conveyor belt for transportation and is absorbed and collected by the absorption mechanism. Then, the lower mold is placed on the second conveyor belt, and under the action of the rotating mechanism, the upper mold, the guard plate casting or the lower mold can be swung back and forth during adsorption, so as to facilitate the shedding of the molding sand. After the molding sand is transported forward, the first motor is started to rotate the baffle upward. At this time, the lower mold, the upper mold and the guard plate casting can be transported on the second conveyor belt and can fall into the collection frame for collection respectively, so that after the sand casting is completed, it is convenient to carry out the discharging operation of the guard plate casting body, and it is convenient to carry out the sand casting mold. , guard plate castings and molding sand are collected separately, which is more convenient and quick to use, and can improve the efficiency and safety of sand casting. During adsorption, when the fixed plate approaches the adsorption surface, when the ball is against the adsorption surface, when the electromagnet continues to move, the sixth spring is gradually compressed. At the same time, the electromagnet can be against the inclined surface, thereby pushing the two second movable plates to move away from each other. At the same time, the fifth spring is compressed, and the two third movable plates are driven to move away from each other through the telescopic mechanism, so that the second brush can automatically clean the adsorption surface and ensure that the electromagnet can normally contact the adsorption surface, thereby making the adsorption more stable and reliable, and ensuring the adsorption effect.

[0021] (2) The excavator guard plate casting discharging device is provided with a first cleaning mechanism, etc., and after the electromagnet sequentially adsorbs and lifts the upper mold, the guard plate casting or the lower mold, the third moving block can be driven by the third moving module to move in the direction close to the first L-shaped plate. At the same time, the first moving mechanism drives the connecting plate and the U-shaped plate to move, thereby driving the fourth moving block, the connecting rod and the first brush to move synchronously through the second moving mechanism. When the stopper block abuts against the side wall of the first L-shaped plate, the upper mold, the guard plate casting or the lower mold is between the connecting rods. When the third moving block continues to move, the third L-shaped plate drives the inclined plate to continue to move, so that the distance between the third moving block and the U-shaped plate becomes smaller. At the same time, the first spring is compressed, and the inclined plate abuts against the end of the first T-shaped guide rod, so that the two fourth moving blocks of each group can be pushed. The moving block and the connecting rod move close to each other, and make the first brush abut against the top and bottom of the upper mold, the guard plate casting or the lower mold. At the same time, when the third moving block moves close to the U-shaped plate, it drives the mounting plate and the triangular block to move synchronously. When the first pushing block abuts against the side wall of the triangular block, it can push the U-shaped plate to move, and at the same time, drive the connecting plate to move in the direction close to the fifth moving block. The second spring is compressed. When the triangular block passes over the first pushing block, the U-shaped plate can move and reset under the action of the second spring. This reciprocating process can make the U-shaped plate reciprocate and drive the connecting rod and the first brush to reciprocate, so that the surface of the upper mold, the guard plate casting or the lower mold can be automatically cleaned, which is convenient for cleaning the residual molding sand. The cleaned molding sand falls on the second conveyor belt for transportation to ensure the discharge effect.

[0022] (3) This type of excavator guard plate casting discharging device is provided with an absorption mechanism, etc., and when discharging, the exhaust fan is started. At this time, the air is exhausted through the connecting pipe and the absorption pipe, and then the air is exhausted through the conical cover. At this time, the molding sand falling on the second conveyor belt can be sucked into the conical cover through the through hole, and enter the filter box through the absorption pipe. Under the filtering action of the filter, the absorbed molding sand falls into the collection box for collection. The filtered air enters the working box through the connecting pipe and is discharged through the exhaust fan, thereby facilitating the collection of the molding sand and improving the collection efficiency and effect.

[0023] (4) The discharging device of the guard plate casting of the excavator is provided with a crushing mechanism, etc. When the molding sand is conveyed on the second conveyor belt, when the filtered air enters the working box, it will impact the surface of the rotating fan to make it rotate, thereby driving the cam to rotate through the rotating rod. When the tip of the cam abuts against the bottom of the second push block, it can push the second push block and the first moving plate to move upward. At the same time, the fourth spring is compressed. When the tip of the cam passes over the bottom of the second push block, the first moving plate can move downward and reset under the action of the fourth spring. In this way, the conical rod of the first moving plate belt can be reciprocated up and down, so as to facilitate the crushing of the agglomerated molding sand, so that the absorption efficiency and effect of the absorption mechanism on the molding sand are higher, so that the discharging effect is better, and when the upper mold, the guard plate casting or the lower mold abuts against the side wall of the conical rod, it can push the conical rod to move upward to ensure that it can normally pass over the conical rod for transportation.

This reciprocating motion can make the conical rod 2603 carried by the first movable plate 2602 move back and forth up and down, thereby facilitating the crushing of the agglomerated molding sand, making the absorption mechanism 27 more efficient and more effective in absorbing the molding sand, thereby achieving better material discharging effect. In addition, when the upper mold 1302, the guard plate casting or the lower mold 1301 abuts against the side wall of the conical rod 2603, it can push the conical rod 2603 to move upward, ensuring that it can normally pass over the conical rod 2603 for transportation.

[0048] The rotating mechanism 8 includes two symmetrically arranged first L-shaped blocks 801 fixed on the side walls of the fixed plate 20, and the opposite side walls of the two first L-shaped blocks 801 are rotatably connected to two symmetrically arranged rotating plates 803 through a rotating shaft 802. The electromagnet 21 is fixed to the side walls of the rotating plate 803, and the side walls of one of the first L-shaped blocks 801 are fixedly connected to a second motor 804, and the output end of the second motor 804 is fixed to one end of the rotating shaft 802. The distance between the electromagnet 21 and the fixed plate 20 is sufficient to ensure that the electromagnet 21 can rotate to a vertical state. The second motor 804 is started. When the second motor 804 rotates, it drives the rotating plate 803 to rotate through the rotating shaft 802, and then drives the electromagnet 21 to rotate. Not only can the angle of the electromagnet 21 be changed, but also during adsorption, the upper mold 1302, the guard plate casting or the lower mold 1301 can be reciprocated and swung, thereby facilitating the shedding of the molding sand.

[0049] The reset mechanism 6 includes two symmetrically arranged fourth T-shaped guide rods 602 fixedly connected to the side walls of each second movable plate 2801, the side walls of the fourth T-shaped guide rods 602 are sleeved with a second L-shaped block 601, the second L-shaped block 601 is fixed to the side wall of the electromagnet 21, and the side walls of each fourth T-shaped guide rod 602 are sleeved with a fifth spring 603, which guides and resets the movement of the second movable plate 2801.

[0050] The telescopic mechanism 9 includes two symmetrically arranged third sleeves 901 fixedly connected to the bottom of each second movable plate 2801, and each third sleeve 901 is inserted with a third sleeve rod 902, the lower end of the third sleeve rod 902 is fixed to the top of the third movable plate 2803, and the side wall of each third sleeve 901 is sleeved with a sixth spring 903. During adsorption, when the fixed plate 20 approaches the adsorption surface, when the ball 2806 abuts against the adsorption surface, when the electromagnet 21 continues to move, the sixth spring 903 is gradually compressed. At the same time, the electromagnet 21 can abut against the inclined surface 2802, thereby pushing the two second movable plates 2801 to move away from each other. At the same time, the fifth spring 603 is compressed and drives the two third movable plates 2803 to move away from each other through the telescopic mechanism 9, so that the second brush bristles 2804 can automatically clean the adsorption surface and ensure that the electromagnet 21 can normally contact the adsorption surface, thereby making the adsorption more stable and reliable, and ensuring the adsorption effect.

[0051] The pushing mechanism 10 includes a support plate 1001 fixedly connected to the top of the base plate 1, and the side wall of the support plate 1001 is fixedly connected to a cylinder 1002, and the telescopic end of the cylinder 1002 is fixedly connected to a push plate 1003. The guard plate casting after sand casting is conveyed along with the sand casting mold 13 on the first conveyor belt 1101. When it is conveyed to one side of the push plate 1003, the cylinder 1002 is started, and the sand casting mold 13 is pushed to the second conveyor belt 1201 for transportation through the push plate 1003.

[0052] Working principle: When in use, the guard plate casting after sand casting is conveyed along with the sand casting mold 13 on the first conveyor belt 1101. When it is conveyed to one side of the push plate 1003, the cylinder 1002 is started, and the sand casting mold 13 is pushed to the second conveyor belt 1201 for conveying through the push plate 1003. When the sand casting mold 13 abuts against the baffle 23, it is blocked; then, the first moving block 17 is driven to move by the first moving module 16, and at the same time, the second moving block 19 is driven to rise and fall by the second moving module 18, so that the electromagnet 21 can be moved to the top of the upper mold 1302, and then, the electromagnet 21 is energized, at this time, the upper mold 1302 can be adsorbed, and at the same time, the molding sand in the upper mold 1302 can fall on the second conveyor belt 1201 for conveying, and when it is moved to the top of the second conveyor belt 1201, the electromagnet 21 is powered off, so that the upper mold 1302 can be placed on the second conveyor belt 1201;

[0053] Next, the guard plate casting in the sand casting mold 13 can be adsorbed by the electromagnet 21 and placed on the second conveyor belt 1201, and then the second motor 804 is started. When the second motor 804 rotates, the rotating plate 803 is driven to rotate through the rotating shaft 802, thereby driving the electromagnet 21 to rotate and rotate 90 degrees to a vertical state. Next, the side wall of the lower mold 1301 is adsorbed by the electromagnet 21, and then the second motor 804 is started to reverse and the electromagnet 21 is rotated 180 degrees in the opposite direction, thereby conveying The movable lower mold 1301 is turned over 180 degrees to turn it over, so that the molding sand inside it falls on the second conveyor belt 1201 for transportation and is absorbed and collected by the absorption mechanism 27. Then, the lower mold 1301 is placed on the second conveyor belt 1201. At the same time, the lower mold 1301, the upper mold 1302 and the guard plate casting are placed separately. Under the action of the rotating mechanism 8, the upper mold 1302, the guard plate casting or the lower mold 1301 can be reciprocated during adsorption, so as to facilitate the shedding of the molding sand.

[0054] Moreover, when adsorption is performed, when the fixed plate 20 approaches the adsorption surface, after the ball 2806 abuts against the adsorption surface, when the electromagnet 21 continues to move, the sixth spring 903 is gradually compressed, and at the same time, the electromagnet 21 can abut against the inclined surface 2802, thereby pushing the two second movable plates 2801 to move away from each other. At the same time, the fifth spring 603 is compressed, and the two third movable plates 2803 are driven to move away from each other through the telescopic mechanism 9, so that the second bristles 2804 can automatically clean the adsorption surface, and ensure that the electromagnet 21 can normally contact with the adsorption surface, and is energized when in contact, so that the adsorption is more stable and reliable, ensuring the adsorption effect;

[0055] After the electromagnet 21 successively absorbs and lifts the upper mold 1302, the guard plate casting or the lower mold 1301, the third moving block 2502 can be driven by the third moving module 2501 to move toward the first L-shaped plate 15. At the same time, the connecting plate 2503 and the U-shaped plate 2504 are driven to move by the first moving mechanism 2, so that the fourth moving block 2505, the connecting rod 2506 and the first brush 2507 are driven to move synchronously by the second moving mechanism 3. When the stop block 2508 abuts against the side wall of the first L-shaped plate 15, , the upper mold 1302, the guard plate casting or the lower mold 1301 are between the connecting rod 2506. When the third moving block 2502 continues to move, the third L-shaped plate 401 drives the inclined plate 402 to continue to move, so that the distance between the third moving block 2502 and the U-shaped plate 2504 becomes smaller. At the same time, the first spring 204 is compressed, and the inclined plate 402 is abutted against the end of the first T-shaped guide rod 301, so that each group of two fourth moving blocks 2505 and the connecting rod 2506 can be pushed to move closer to each other, and the first brush 2507 is close to the upper mold 1 302, the top and bottom of the guard plate casting or the lower mold 1301 are against each other. At the same time, when the third moving block 2502 moves close to the U-shaped plate 2504, it drives the mounting plate 501 and the triangular block 502 to move synchronously. When the first pushing block 503 is against the side wall of the triangular block 502, it can push the U-shaped plate 2504 to move, and at the same time, drive the connecting plate 2503 to move in the direction close to the fifth moving block 203, the second spring 207 is compressed, and when the triangular block 502 passes over the first pushing block 503, the U-shaped plate 2504 It can move and reset under the action of the second spring 207, and reciprocate in this way, so that the U-shaped plate 2504 can reciprocate, and drive the connecting rod 2506 and the first brush 2507 to reciprocate, so that the surface of the upper mold 1302, the guard plate casting or the lower mold 1301 can be automatically cleaned. The first brush 2507 can extend into the upper mold 1302 and the lower mold 1301 and abut against the top and bottom thereof, so as to clean the residual molding sand. The cleaned molding sand falls on the second conveyor belt 1201 for transportation, thereby ensuring the discharge effect;

[0056] After the molding sand is transported forward, the first motor 22 is started to rotate the baffle plate 23 upward. At this time, the lower mold 1301, the upper mold 1302 and the guard plate casting can be transported on the second conveyor belt 1201 and can be respectively dropped into the collection frame 24 for collection, so that after the sand casting is completed, it is convenient to carry out the material discharge operation on the guard plate casting body, and it is convenient to collect the sand casting mold 13, the guard plate casting and the molding sand separately, which is more convenient and quick to use and can improve the efficiency and safety of sand casting;

[0057] When discharging, the exhaust fan 2705 is started. At this time, the air is exhausted through the connecting pipe 2704 and the absorption pipe 2702, and then the air is exhausted through the conical cover 2703. At this time, the molding sand falling on the second conveyor belt 1201 can be sucked into the conical cover 2703 through the through hole 14, and enter the filter box 2701 through the absorption pipe 2702. Under the filtering effect of the filter screen 2708, the absorbed molding sand falls into the collection box 2706 for collection. The filtered air enters the working box 701 through the connecting pipe 2704 and is discharged through the exhaust fan 2705, so that the molding sand can be collected easily and the collection efficiency and effect can be improved.

[0058] Furthermore, when the molding sand is conveyed on the second conveyor belt 1201, when the filtered air enters the working box 701, it will impact the surface of the rotating fan 703 to make it rotate, thereby driving the cam 704 to rotate through the rotating rod 702. When the tip of the cam 704 abuts against the bottom of the second pushing block 705, the second pushing block 705 and the first moving plate 2602 can be pushed upward. At the same time, the fourth spring 707 is compressed. When the tip of the cam 704 passes over the bottom of the second pushing block 705, the first moving plate 2602 can It can move downward and reset under the action of the fourth spring 707, and so on, so that the conical rod 2603 carried by the first movable plate 2602 can move up and down reciprocatingly, so as to facilitate the crushing of the agglomerated molding sand, so that the absorption efficiency and effect of the absorption mechanism 27 on the molding sand are higher, so as to achieve better material discharge effect, and when the upper mold 1302, the guard plate casting or the lower mold 1301 are against the side wall of the conical rod 2603, the conical rod 2603 can be pushed to move upward to ensure that it can normally cross the conical rod 2603 for transportation.
