DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0016] Please refer to Figs. 1-3 The utility model provides a kind of technical scheme: a kind of waste sand recovery device of sand coated iron mold casting process, including conveying belt 1, the outer wall of conveying belt 1 is fixedly connected with mounting plate 2, the top of mounting plate 2 is fixedly connected with first gear 3, the bottom of mounting plate 2 is fixedly installed with motor 4, motor 4 output end is fixedly connected with mounting seat 5 through mounting plate 2, mounting seat 5 is rotatably connected with screw rod 6, second gear 7 is fixedly connected with the position corresponding first gear 3 at the bottom of screw rod 6, sliding groove 8 is opened in mounting seat 5, mounting seat 5 is opened with the clamping groove 9 of symmetrical arrangement, sliding groove 8 is slidably connected with lifting plate 10 inside, lifting plate 10 is fixedly connected with clamping block 11 at the position corresponding two clamping grooves 9, lifting plate 10 bottom is fixedly connected with magnet 12, magnet 12 bottom is equipped with wood board insulation layer 13, lifting plate 10 top is fixedly connected with connecting frame 14, connecting frame 14 is slidably connected with lifting frame 15 inside.

[0017] Furthermore, the output end of the motor 4 passes through the mounting plate 2 and is fixedly connected to the mounting base 5 at the center position of the first gear 3, so that the motor 4 can easily drive the mounting base 5 to rotate.

[0018] Furthermore, the diameter of the first gear 3 is larger than that of the second gear 7 , and the first gear 3 is meshed with the second gear 7 , so that the first gear 3 facilitates the rotation of the second gear 7 .

[0019] Furthermore, the sliding groove 8 is in communication with the two clamping grooves 9 , and the clamping blocks 11 are slidably connected inside the clamping grooves 9 .

[0020] Furthermore, the lifting frame 15 is threadedly connected to the screw rod 6, and the screw rod 6 is convenient for driving the lifting frame 15 to move.

[0021] The conveyor belt 1 is then started to transport the waste sand toward the magnet 12. The magnet 12 continuously absorbs the broken iron in the waste sand, and the wooden insulating layer 13 prevents the bottom end of the magnet 12 from adsorbing the broken iron, so the broken iron is adsorbed on the outer wall of the magnet 12. When the magnet 12 is full of broken iron, the motor 4 is started. The motor 4 drives the mounting base 5 to rotate to one side. The rotating mounting base 5 drives the screw rod 6, the lifting plate 10 and the magnet 12 to rotate. The screw rod 6 rotates with the mounting base 5 and also drives the second gear 7 to rotate together. The second gear 7 rotates by itself due to the first gear 3. The second gear 7 rotates by itself following the rotation of the mounting base 5. When the lifting plate 10 is lifted up, the lifting plate 10 will move upward. After it moves up a certain distance, the square block will abut against the top wall of the connecting frame 14, thereby driving the connecting frame 14 and the lifting plate 10 to move upward during the rotation. At this time, the mounting seat 5 is no longer at the top of the conveyor belt 1, and the lifting plate 10 moves upward to drive the magnet 12 to move upward. The magnet 12 moves upward, and the broken iron on the magnet 12 abuts against the bottom end of the mounting seat 5. When the magnet 12 moves completely to the inside of the chute 8, all the broken iron will lose the adsorption of the magnet 12 and fall to the ground. At this time, the motor 4 drives the mounting seat 5 to rotate in the opposite direction of the conveyor belt 1, and the retraction of the magnet 12 will cause all the broken iron to fall to the ground. After completing the above steps, each mechanism can be reset to its original position again, and this can be repeated. Multiple recovery devices can be set up on the conveyor belt 1 to stagger the rotation time of multiple mounting seats 5, so that the conveyor belt 1 can continuously transport and select waste sand.

[0022] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
