[0019] The present invention provides embodiment 1:

[0020] like Figure 1-4As shown, a self-actuated automatic dumping device comprises a self-frame 1, a plurality of sets of running wheels 2 are installed at the bottom of the self-frame 1, and the plurality of running wheels 2 run on a track 201, and side panels 7 are symmetrically installed on the left and right sides of the top of the self-frame 1, and a walking guide mechanism is installed above the self-frame 1, and a plurality of sets of compression spring mounts 8 are installed between the side panels 7 on the left and right sides of the top of the self-frame 1, and a transversely arranged lower door latch 12 is installed on the top of the plurality of compression spring mounts 8, and an upper door latch 13 is installed above the lower door latch 12, and at the same time, an angular protrusion 1201 with an inclined angle of 15 degrees is provided on the top of the lower door latch 12, which is matched with an angular groove 1301 with an inclined angle of 15 degrees provided on the bottom of the upper door latch 13, and the upper door latch 13 is installed on the top There are multiple groups of vertically limited gantry frames, and top support plates 14 are symmetrically installed at both ends of the lower door latch 12. The top of the top support plate 14 supports an eccentric bracket unit with an automatic reset function installed in the first groove 701 on the lower side. The inner and outer sides of the side plate 7 on the side pointed by the angular protrusion 1201 are respectively provided with a second sliding groove 703 and a trigger member socket 704. A trigger member through groove 1401 is provided between the second sliding groove 703 and the trigger member socket 704 and on the top support plate 14. The height of the trigger member through groove 1401 is greater than the height of the second sliding groove 703. A reset spring frame 11 is installed at the non-trigger end of the upper door latch 13. The reset spring frame 11 is composed of a telescopic rod and a spring known on the market.

[0021] Working principle:

[0022] When the device arrives at the predetermined unloading space with the workpiece, the unloading trigger 6 installed at a fixed point in the unloading space is inserted into the trigger hole 704, the trigger through slot 1401 and the second sliding slot 703 on the side plate 7 and the top support plate 14 in sequence, and pushes the upper latch 13 to move inward. During the movement of the upper latch 13 inward, the angular protrusion 1201 of the lower latch 12 is squeezed through the angular groove 1301, so that the lower latch 12 moves downward. The downward movement of the lower latch 12 drives the top support plates 14 at both ends to move downward, and the bottom of one side of the eccentric support fork 15 is pressed downward. After losing the support of the top supporting plate 14, it rotates toward the lower material side so that the top workpiece slides down automatically. The height of the trigger member penetrating the groove 1401 is greater than the height of the second sliding groove 703, and the unloading trigger member will not be stuck. After the automatic unloading is completed, the eccentric support fork 15 is reset by the reset spring 16, and the lower door latch 12 is reversely squeezed by multiple groups of compression spring brackets 8 and drives the upper door latch 13 to reset. The function of automatic unloading at a designated location is realized through the above mechanism, which avoids the time-consuming and labor-intensive manual handling, greatly improves the working efficiency and reduces the construction cost.

The top support plate 14 is inserted into the bracket groove 1502 to support the eccentric support fork 15 to meet the stability of the storage component on the top of the eccentric support fork 15.

[0027] like Figure 1-4 As shown, the two ends of the lower door latch 12 are respectively inserted into the first sliding groove 702 and the second sliding groove 703 connected to the first groove 701 provided at the bottom of the side panels 7 at both ends. The height of the first sliding groove 702 is smaller than the second sliding groove 703. A discharge trigger 6 is placed at a fixed point in the working space of the discharge point, and one end can be inserted into the trigger member socket 704, the trigger member through groove 1401 and the second sliding groove 703 in turn to push the upper door latch 13 to move inward.
