The inner end of each locking block 261 is connected with a second return spring 264, and the second return spring 264 is compressed when the locking block 261 moves inwards, and drives the locking block 261 to move outwards and return when the external force applied to the locking block 261 disappears. In order to prevent the two locking blocks 261 from falling out of the mounting grooves 026 under the action of the second return spring 264, the two locking blocks 261 are connected by a connecting rod 265, and correspondingly, a shallow groove 027 communicating the two mounting grooves 026 is formed on the main body, and the shallow groove 027 enables the top surface of the connecting rod 265 to be lower than the top surface of the second rod 217, thereby facilitating the installation of the sealing plate 218.

Normally, as shown in fig. 9, the first return spring 263 makes the slider 262 in an extended state, and the second return spring 264 makes the two locking blocks 261 in an extended state, and at this time, the two locking blocks 261 are extended to the inner side of the square hole 025 and inserted into the locking hole 243 of the locking plate 242 of the tray in the closed position.

As shown in fig. 10, for the convenience of assembly, the slider 262 further includes a bar 028, one end of the bar 028 abuts against the protrusion 022, and the other end of the bar 028 is flush with the inner end of the main body 02 and is connected to a first return spring 263, and the first return spring 263 keeps the bar 028 in abutment against the protrusion 022. Meanwhile, the long bar 028 is abutted against the outer side 024 of the main body 02 facing away from the tray 24, the sum of the widths of the long bar 028 and the main body 02 corresponds to the width of the wide part 012 of the groove 01, the mounting groove 026 extends to the outer side 024 of the main body 02, the long bar 028 is provided with spring installation grooves (not shown) facing the two mounting grooves 026 toward the side of the mounting groove 026, and the second return spring 264 is partially embedded in the spring installation groove 029, so that when the length of the mounting groove 026 is smaller than the length of the locking block 261, the locking block 261 is firstly installed in the square hole 025, and then the long bar 028 and the second return spring 264 are installed.

As shown in fig. 10 and 11, when the tray 24 is unlocked, the tray is unlocked by applying a pushing force from the outer end of the slider 262, in order to be able to convert the inward movement of the slider 262 into the inward movement of the locking block 261, the first side vertex 101 of the protruding portion 100 of the locking block 261 protruding out of the inner side face 023 of the slider 262 (in the direction when the slider 262 moves inward) is rounded, the driving vertex 208 of the unlocking notch 207 biased toward the inner end of the groove 01 is a chamfer or a fillet, so that, as the slider 262 moves into the recess 01, by the cooperation of the first side corner with the driving corner, the cambered surface or the inclined surface of the driving vertex 208 can drive the locking block 261 to move towards the long block 028 until the locking block 261 is withdrawn from the locking hole 243, namely, the tray 24 is unlocked.

As shown in fig. 12 and 13, the ring-shaped track 1 is provided with a plurality of opening driving mechanisms 6 for driving the opening and closing linkage mechanisms 26 to open the trays 24, the opening driving mechanisms 6 are located at two sides of the bag falling sorting trolley, four opening driving mechanisms are a group for driving four trays (each tray corresponds to one opening and closing linkage mechanism) on one bag falling sorting trolley to open, when one bag falling sorting trolley moves to correspond to one group of opening driving mechanisms, each opening driving mechanism 6 is matched with one opening and closing linkage mechanism 26 on the bag falling sorting trolley 2 to open one tray 24, so that the four trays 24 can be effectively and independently opened. The opening drive mechanism 6 is preferably a push type electromagnet mechanism, but may be replaced by a pneumatic cylinder, a hydraulic cylinder, a linear motor, or the like.

As shown in fig. 12 and 13, since the opening driving mechanism 6 is disposed at the side of the track, and the linear motor primary 4 for driving the trolley to rotate circularly is also disposed at the side of the track, in order to avoid interference between the opening driving mechanism 6 and the linear motor primary 4, the opening driving mechanism 6 is disposed at the inner side and the outer side of the circular track 1 through the bracket 7. The support 7 is preferably a U-shaped support 7, and of course, other shapes may be used, the U-shaped support may effectively avoid the secondary plate and the U-shaped mounting rack where the secondary plate is located, the top plate 71 of the support 7 is higher than the top of the frame 21 of the bag falling sorting trolley 2, and the opening driving mechanism 6 is disposed on the top plate 71 of the support 7, so that, in the above description, making the top of the secondary plate 3 lower than the frame 21 may effectively reduce the height required by the support 7, and thus, the installation of the opening driving mechanism 6 may be implemented by adopting a simpler structure. Correspondingly, the outer end of the main body 02 of the sliding part 262 is provided with a stress plate 03 which is bent upwards by 90 degrees, and the top of the stress plate 03 is higher than the telescopic rod of the opening driving mechanism 6, so that the opening driving mechanism 6 can be driven effectively.

Of course, in another embodiment, the locking plate 242 may extend above the top of the frame 21, and the locking hole 243 is located above the top of the frame 21, in which case, the opening and closing linkage mechanism 26 is directly disposed on the top of the second rod 217, and a certain structure is required to mount the sliding member 262.

After the tray 24 is opened, the tray 24 needs to be restored to the closed state through a certain closing mechanism under the condition that the tray 24 is opened, and meanwhile, in the process that the tray 24 is closed, the tray 24 and the opening and closing linkage mechanism 26 are linked to realize the locking of the tray 24 in the closed state.

As shown in fig. 14 and 15, the closing mechanism includes a reset wheel 8 and a reset sheet 9 for driving the reset wheel to lift, the reset wheel 8 is disposed at the bottom of each tray 24, and is close to the second long side 244 (the side of the tray 24 opposite to the hinged side of the frame 21) and the front side 245 (the side of the tray facing forward during the movement of the drop sorting cart) of the tray 24, and the axes of the trays 24 are parallel to the axes of the traveling wheels 22 in the closed state. The reset plate 9 is arranged below the inner and outer rails 11, the reset plate 9 comprises two symmetrical spiral plates 91, the lower ends of the spiral plates 91 are connected to a support leg 13, the upper ends of the spiral plates 91 are provided with horizontal plates 92, and the horizontal plates 92 connected with the two spiral plates 91 are connected with each other. Preferably, a support structure may be disposed below the horizontal plate 92 to prevent the spiral sheet 91 from deforming under a long-term stress, and the support structure may be a structure having elasticity.

After the bag falling sorting trolley 2 finishes sorting, at least one tray 24 on the bag falling sorting trolley is in an open state, when the bag falling sorting trolley 2 moves to the spiral sheet 91 on the corresponding side of the tray 24, the reset wheel 8 on the back of the opened tray 24 climbs upwards along the spiral sheet 91 from the lower end of the spiral sheet 91, the reset wheel 8 climbs to drive the second long side of the tray 24 to rotate and lift, and when the reset wheel 8 moves to the horizontal plate 92 on the upper end of the spiral sheet 91, the tray 24 returns to a closed position (the tray is in a horizontal state). Due to the spiral piece 91, the reset wheel 8 and the spiral piece 91 can be contacted more fully and crawl upwards slowly, so that the closing of the tray 24 is more linear and soft.

After the tray 24 is rotated to the closed position, the opening/closing linkage 26 locks the tray 24 in the closed position again by the locking piece 261. In order to realize automatic locking, as shown in fig. 11, the lower corner 102 of the protruding portion 100 of the locking block 261 protruding out of the unlocking notch 207 is rounded or chamfered, so that during the rotation and lifting of the tray 24, the locking plate 242 contacts the lower corner of the locking block 261, and as the locking plate 242 is lifted, the locking block 261 is pushed by the locking plate 242 to move towards the long bar 028, and when the locking hole 243 on which the locking plate 242 is lifted is aligned with the locking block 261, the locking block 261 is quickly reset under the reaction force of the second return spring 264 and is inserted into the locking hole 243 to realize locking of the tray 24. With the structure, the whole locking process is quick and gentle, mutual abrasion among mechanisms is hardly caused, and the service life of the equipment can be prolonged to the maximum extent.
