The driving member 441 and the movable baffle 43 are detachably connected.

[0038] When the automatic counting device is in use, the feeding device 1 delivers the perforating shells to the feeding port of the elevator 12 through the tipping machine 11, and the elevator 12 lifts the perforating shells onto the dividing wheel 13. The outer wall of the dividing wheel 13 is arranged with multiple partitions 131 along its circumference. The space between two adjacent partitions 131 can accommodate multiple perforating shells distributed side by side, and can guide a plurality of perforating shells to the feeding end of the upper conveyor belt 22, so that the perforating shells are arranged more dispersedly and evenly on the upper conveyor belt 22, without manual paving, and the guide plate 201 guides the perforating shells output by the upper conveyor belt 22 to fall to the feeding side of the lower conveyor belt 23. The guide structure 233 separates the multi-count conveyor belt 231 and the single-count conveyor belt 232, so that each perforation shell on the lower conveyor belt 23 is fed to the discharge hopper 231 by the multi-count conveyor belt 231 and the single-count conveyor belt 232 respectively after diversion feeding, and each perforation shell is collected in the collection box 24 through the opening of the discharge hopper 231. The detection device 3 collects the image of the opening of the discharge hopper 231 through the visual counting camera 31. The information of the image includes the number of perforation shells output from the discharge end of the multi-count conveyor belt 231 and the number of perforation shells output from the discharge end of the single-count conveyor belt 232, and the information of the image is displayed through the display screen 33.

[0039] The staff can switch the movable baffle 43 to the initial state or the expanded state through the diversion switching device 4 according to the needs, so that the material drop counting of the multi-counting conveyor belt 231 and the material drop counting of the single-counting conveyor belt 232 can be carried out independently or simultaneously, which effectively reduces the phenomenon of overlapping and crossing of perforating shells, improves the accuracy and precision of the points, and has good flexibility in use.

[0040] Driven by the driving device 44, the movable baffle 43 swings to the initial state or the expanded state in the feeding channel of the upper conveyor belt 22. In the initial state, the movable baffle 43 cooperates with the mounting plate 41, and the feeding end of the multi-count conveyor belt 231 and the feeding end of the single-count conveyor belt 232 are both connected to the feeding channel of the upper conveyor belt 22. The perforating shells output by the upper conveyor belt 22 are respectively dropped onto the feeding end of the multi-count conveyor belt 231 and the feeding end of the single-count conveyor belt 232. The automatic technical equipment can simultaneously perform the dropping counting of the multi-count conveyor belt 231 and the dropping counting of the single-count conveyor belt 232, and is suitable for the feeding counting needs of large quantities of perforating shells.

[0041] The side of the movable baffle 43 away from the movable sleeve 432 is formed with a matching plate 433, and the end surface of the driving member 441 is formed with an abutting surface 442. The driving device 44 drives the driving member 441 to extend into the feeding channel of the upper conveyor belt 22, and the driving member 441 abuts against the inner side wall of the movable baffle 43 to apply pressure to make it swing close to the mounting plate 41 until the matching plate 433 abuts against the inner side wall of the fixed baffle 42. When the movable baffle 43 is in the unfolded state, the space between the feeding channel of the upper conveyor belt 22 and the feeding end of the multi-counting conveyor belt 231 is blocked by the movable baffle. The plate 43 covers to prevent the perforating shells on the upper conveyor belt 22 from moving to the feed end of the multi-count conveyor belt 231, and the abutment surface 442 cooperates with the inner wall of the movable baffle 43 close to it to maintain the position of the movable baffle 43. Preferably, a mounting frame 411 for mounting the driving device 44 is provided on the mounting plate 41, so that a height difference is formed between the driving device 44 and the upper conveyor belt 22, and an escape space for the perforating shells to pass through is formed between the driving device 44 and the upper conveyor belt 22, so as to prevent the driving device 44 from interfering with the upper conveyor belt 22 in transporting the perforating shells. A through hole 431 for a single perforating shell to pass through is formed in the movable baffle 43 at a position relative to the single counting conveyor belt 232, so that the feeding channel of the upper conveyor belt 22 is only connected to the feeding end of the single counting conveyor belt 232, and each perforating shell outputted by the upper conveyor belt 22 is only dropped onto the feeding end of the single counting conveyor belt 232. The automatic technical equipment can count the dropped shells of the single counting conveyor belt 232 separately, which is suitable for the feeding counting needs of small batches of perforating shells, and the information collected by the visual counting camera 31 includes the number of perforating shells outputted from the discharging end of the single counting conveyor belt 232. The single counting conveyor belt 232 sequentially conveys single perforating shells to the discharging hopper 231, avoiding the phenomenon of overlapping and crossing of perforating shells, making the technology more accurate.

[0042] Preferably, an angle a is formed between the movable baffle 43 in the expanded state and the width direction of the upper conveyor belt 22 , and the angle a is an acute angle, so that the inner side wall of the movable baffle 43 can guide the perforating shell to move toward the through hole 431 .

[0043] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
