[0079] The difference from Example 1 is that Figure 3-Figure 5 As shown, the box bottom 2 includes two bottom plates 21 in a split structure, and opposite ends of the two bottom plates 21 are hinged to the material box body 1;

[0080] The slide rod assembly includes two slide rods 8 respectively connected to the corresponding base plates 21 , one end of the slide rod 8 is hinged to the corresponding base plate 21 , and the other end of the slide rod 8 is hinged to the connecting block 3 .

[0081] The specific implementation of the discharge box in Example 1 or Example 2 is as follows: Figure 10 As shown:

[0082] When the material box stores iron filings in the workshop, under the action of the spring 73, the telescopic rod 7 drives the shell 51 to the lowest position. At this time, the lever 56 is located at the trough of the corrugated channel 55. At this time, the lock head 54 is located in the accommodating cavity 42 and the lock head 54 is in a semi-locked position. The angle between the length direction of the lock head 54 and the length direction of the lock hole 41 is 45°.

[0083] When the iron filings in the bin need to be processed, the bin is lifted by hooking the two lifting rings 71 with a crane hook. During lifting, the spring 73 is first compressed, and the telescopic rod 7 drives the housing 51 and the lever 56 upward. To accommodate the upward movement of the lever 56, the lock column 52 drives the corrugated channel 55 to rotate, causing the contact position between the lever 56 and the corrugated channel 55 to change from the trough to the crest. When the bin is fully lifted, the lock column 52 rotates 45°, and the angle between the length of the lock head 54 and the length of the lock hole 41 becomes 90°. The lock head 54 rotates to the locked position, and the contact position between the lever 56 and the corrugated channel 55 changes from the trough to the crest.

[0084] When the material box is hoisted to the location where it needs to be unloaded, it is lowered. When the material box touches the ground or the iron filings pile, the spring 73 begins to gradually release. Under the action of the spring 73, the telescopic rod 7 drives the housing 51 and the lever 56 downward. In order to adapt to the downward movement of the lever 56, the lock column 52 drives the corrugated channel 55 to rotate, so that the contact position of the lever 56 and the corrugated channel 55 changes from the crest to the next trough. When the material box lands, the lock column 52 rotates another 45°, and the angle between the length direction of the lock head 54 and the length direction of the lock hole 41 becomes 135°. The lock head 54 rotates to the semi-locked position, and the contact position of the lever 56 and the corrugated channel 55 changes from the crest to the next trough.

[0085] The crane hook is then used to hook the two lifting rings 71 to lift the bin. During lifting, the spring 73 is first compressed, and the telescopic rod 7 drives the housing 51 and the lever 56 upward. To accommodate the upward movement of the lever 56, the lock column 52 rotates the corrugated channel 55, causing the contact position between the lever 56 and the corrugated channel 55 to change from the trough to the crest. When the bin is fully lifted, the lock column 52 rotates another 45°, and the angle between the length of the lock head 54 and the length of the lock hole 41 becomes zero. The lock head 54 rotates to the unlocked position, and the contact position between the lever 56 and the corrugated channel 55 changes from the trough to the crest. At this point, the lock head 54 is released from the lock hole 41. Under the weight of the iron filings inside, the bin bottom 2 opens, allowing unloading.

[0086] After the iron filings are unloaded, the crane hook lifts the empty material box to its initial working position and then lowers it. When the empty material box touches the ground, spring 73 begins to gradually release. Under the action of spring 73, the telescopic rod 7 drives the housing 51 and the lever 56 downward. To accommodate the downward movement of the lever 56, the lock column 52 drives the corrugated channel 55 to rotate, causing the contact position of the lever 56 and the corrugated channel 55 to change from the crest to the next trough. When the empty material box lands, the lock column 52 rotates another 45°, and the angle between the length of the lock head 54 and the length of the lock hole 41 becomes 45°. The lock head 54 rotates to its initial semi-locked position, and the contact position of the lever 56 and the corrugated channel 55 changes from the crest to the next trough, that is, the relative position relationship between the lock head 54 and the lock hole 41 is reset to the initial position. During the above process, the lock column 52 rotates clockwise from a top-down perspective.

[0087] The next time the iron chips are unloaded, the above steps are repeated, thereby achieving the goal that the operator no longer needs to climb up to cooperate with the opening and closing of the box bottom 2 when unloading the iron chips, which is easy to operate and improves the working efficiency.

[0088] Although the above describes the specific implementation methods of the present invention in conjunction with the accompanying drawings, it is not a limitation of the present invention. Those skilled in the art should understand that on the basis of the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
