The steel ball roller 231 improves the smoothness when the chute 4 (see fig. 4) is pushed into the drop box 2, and reduces the resistance force applied when the chute 4 is pushed.

Referring to fig. 3, a plugging door 5 (refer to fig. 1) is hinged to one side of the knockout box 2 (refer to fig. 2) provided with the dismounting port 22 (refer to fig. 2), a locking groove 51 is formed in the plugging door 5, a locking block 6 (refer to fig. 1) is fixedly connected to one side of the knockout box 2 provided with the dismounting port 22, and hinged points of the locking block 6 and the plugging door 5 are oppositely arranged on two sides of the dismounting port 22. A bolt 7 passes through the lock slot 51, and a locking notch is arranged on the locking block 6. After the plugging door 5 plugs the dismounting opening 22, the bolt 7 is right opposite to the locking opening, and at the moment, the worker moves the bolt 7, so that the bolt 7 enters the locking opening, and the plugging door 5 is locked. After the plugging door 5 locks the dismounting opening 22, the plugging door 5 extrudes the blanking chute 4, so that the blanking chute 4 can be stably positioned in the sand box 2.

Referring to fig. 3, one end of the latch 7 located in the lock groove 51 is fixedly connected with a limiting disc 71, a reset compression spring 72 is clamped between the limiting disc 71 and the inner side wall of the lock groove 51, and the reset compression spring 72 is sleeved on the latch 7. The supporting frame 8 is transversely spanned on the locking groove 51, the supporting frame 8 is fixedly connected to the plugging door 5, the supporting frame 8 is rotatably connected with an adjusting rod 81, one end of the adjusting rod 81 extends into the locking groove 51 and is fixedly connected with an ejection cam 82, and the ejection cam 82 abuts against the limiting disc 71.

Referring to fig. 3, a hand wheel 83 (refer to fig. 1) is fixedly sleeved at the top end of the adjusting rod 81, when the plugging door 5 plugs the dismounting opening 22, a worker rotates the adjusting rod 81, the adjusting rod 81 drives the ejecting cam 82 to rotate, and the protruding position of the ejecting cam 82 ejects the lock tongue 7, so that the lock tongue 7 enters the lock opening. When the plugging door 5 needs to be opened, the adjusting rod 81 is rotated, the short shaft of the rotating cam is abutted to the bolt 7, and the bolt 7 moves out of the locking notch under the resilience force of the reset pressure spring 72, so that the plugging door 5 is unlocked.

Referring to fig. 1, a guide plate 421 is fixedly connected to the upper surface of the outer support edge 42 (see fig. 4), the longitudinal section of the guide plate 421 is a right triangle, one right-angled edge thereof is fixedly connected to the outer support edge 42, and the other right-angled edge is attached to the inner side wall of the drag flask 2. When waiting the molding sand of separation to get into charging chute 4, through the guide of deflector 421, can reduce the material and pile up the volume on the bearing outer edge 42.

Referring to fig. 2, the side surfaces of the two side supporting outer edges 42 (refer to fig. 4) which are deviated from each other are respectively and fixedly connected with an anti-drop guide rail 422 (refer to fig. 4), and the inner side wall of the sand dropping box 2 is provided with an anti-drop chute 24 for the anti-drop guide rail 422 to slide. The anti-drop chute 24 can limit the anti-drop guide rail 422, and reduces the possibility that the blanking groove 4 is dropped out from the shakeout box 2.

Referring to fig. 2, the shakeout box 2 has a receiving groove 25 formed in a lateral direction with respect to an inner wall of the attachment/detachment port 22, and the receiving groove 25 is formed in a top portion of the chute 4 (see fig. 1). Fixedly connected with rubber strip 26 in holding tank 25, rubber strip 26 is higher than holding tank 25. After the blanking groove 4 is extruded into the blanking box 2 through the plugging door 5, the blanking groove 4 extrudes the rubber strip 26, the rubber strip 26 in a contraction state has a sealing effect, and the possibility that a gap exists between the blanking groove 4 and the blanking box 2 is reduced.

Referring to fig. 2, a contact column 43 (see fig. 4) is fixedly connected to a side surface of the drop chute 4 (see fig. 4) facing the receiving groove 25, a return hole 27 into which the contact column 43 is inserted is opened in the drop flask 2 with respect to an inner side wall of the contact column 43, and a return pressure spring 271 is provided in the return hole 27. After the blanking groove 4 abuts against the inside of the shakeout box 2, the abutting column 43 abuts against the return pressure spring 271, and the return pressure spring 271 has resilience. When the charging conduit 4 is taken out to needs, when clearing up it, the shutoff door 5 (refer to fig. 1) is opened to the staff, and the resilience force of return pressure spring 271 releases this moment, makes charging conduit 4 remove one section distance for the staff can take charging conduit 4 out from knockout box 2 more fast.

Referring to fig. 4, at chute 4 perpendicular to dismouting mouth 22 both sides face fixedly connected with U type handle 28 respectively, the setting of U type handle 28 makes chute 4 pull out more convenient to this has reduced the degree of difficulty that the staff pulled out chute 4.

The specific implementation process comprises the following steps: when the blanking hole 41 of the blanking groove 4 is blocked, the blocking door 5 is opened by a worker, and the blanking groove 4 moves for a certain distance under the resilience force of the return pressure spring 271. The worker then pulls the U-handle 28 to draw the chute 4 out of the drop flask 2 and clean it. After the cleaning is finished, the worker pushes the blanking groove 4 into the blanking box 2 again, and the plugging door 5 is closed.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
