The specific implementation mode is as follows: during operation of the apparatus of the present invention, as shown in fig. 4, 31 and 43, the locking mechanism 19 between the spacing mechanism 25 and the belt unit 24 is in a locked state at a clockwise portion of the belt mechanism 3 from the load 74 to the belt lock 79; as shown in fig. 4 and 43, the goods are firstly placed on the conveyor belt mechanism 3 at the upper goods place 74, as shown in fig. 5, 8 and 9, at this time, the conveyor belt mechanism 3 will support the upper side part of the conveyor belt mechanism 3 under the cooperation of the driving bars 48 on the conveyor belt mechanism and the supporting grooves 16 formed on the supporting bars 14 arranged on the lower base 11, thereby ensuring that the goods can be smoothly transported on the conveyor belt mechanism 3 without deforming the conveyor belt mechanism 3; as shown in fig. 6, 7 and 24, the first driving device 13 will drive the driving shaft 42 to move, and the moving driving shaft 42 will drive the hexagonal driving wheel 41 mounted thereon to rotate, as shown in fig. 7, the hexagonal driving wheel 41 will cooperate with the driving strip 48 mounted on the second connecting plate 50, so that the hexagonal driving wheel 41 will drive the second connecting plate 50 to make circular motion, so that the conveyor belt mechanism 3 will make circular motion, and the goods on the conveyor belt mechanism 3 will be transported; as shown in fig. 11, 12 and 13, when the locking mechanism 19 on the conveyor belt mechanism 3 moves to the unlocking mechanism 82, as shown in fig. 11, the unlocking block 20 at this time will be under the action of the unlocking inclined plane 21 opened thereon, because the locking mechanism 19 at this time continues to move under the action of the circular motion of the conveyor belt mechanism 3, as shown in fig. 38, the unlocking inclined planes 21 on the two unlocking blocks 20 at this time will be in a matching relationship with the first L-shaped motion bar 65 and the second L-shaped motion bar 66, so that the two unlocking blocks 20 at this time will push the first L-shaped motion bar 65 and the second L-shaped motion bar 66 to move, as shown in fig. 39, 41 and 42, the first L-shaped motion bar 65 and the first limiting block 53 at this time are in a fixed connection relationship, so the first L-shaped motion bar 65 at this time will bring the first limiting block 53 into motion, as shown in fig. 32, 36 and 37, the first limiting block 53 will bring the third T-shaped block 68 mounted thereon along the second T-shaped block 68 opened on the receiving groove 61 The slot 62 moves upwards; as shown in fig. 40, at the same time, the second L-shaped moving bar 66 is fixedly connected to the second limiting block 56, so that the second L-shaped moving bar 66 will drive the second limiting block 56 to move, and the second limiting block 56 will drive the second T-shaped block 67 mounted thereon to move along the second T-shaped groove 62 formed on the receiving groove 61; as shown in fig. 30, the volume of the limiting groove 54 formed by the first limiting block 53 and the second limiting block 56 will be increased; as shown in fig. 41, the lower end surface of one side of the second L-shaped moving bar 66 is fixedly mounted on the end surface of the second limiting block 56, and the second L-shaped moving bar 66 is located at the upper side far away from the third gap 69; the lower end face of one side of the first L-shaped moving strip 65 is fixedly mounted on the end face of the first limiting block 53, and the first L-shaped moving strip 65 is positioned on the upper side of the fourth notch 70; the purpose of this design is that when the two unlocking blocks 20 push the first L-shaped moving bar 65 and the second L-shaped moving bar 66 to move, the movement is relative movement, and the movement will make the limiting groove 54 formed by the first limiting block 53 and the second limiting block 56 become larger in volume; so that the latch mounted on the mounting block 43 can be disengaged from the limit groove 54; by the action of the unlocking mechanism 82, as shown in fig. 34 and 35, the spiral spring 59, which is in the compressed state in the initial state, will return to the initial state, so that the first connecting plate 44 and the third connecting plate 52 form an angle; as shown in fig. 10 and 14, the conveyor mechanism 3 will be accelerated by the accelerating device 4 at the conveyor accelerating place 75; the second connecting plate 50 will cooperate with the accelerating friction wheel 17 installed on the second driving device 18, the accelerating friction wheel 17 will accelerate to drive the second connecting plate 50 to move, as shown in fig. 25, 28 and 29, the second connecting plate 50 will drive the third connecting plate 52 to move rapidly under the action of the cylindrical pin, as shown in fig. 33, the two second side lugs 49 on the first connecting plate 44 and the arc middle lug 51 on the third connecting plate 52 are connected together through the rotating shaft 60, so that when the first connecting plate 44 and the third connecting plate 52 are connected together, the gap between two adjacent second connecting plates 50 can be small, the surface of the conveyor belt mechanism 3 can be flat, and the goods can be more stable during transportation; the third connecting plate 52 will rapidly drive the first connecting plate 44 to move in an accelerated manner through the rotating shaft 60, and under the action of the accelerating device 4, the first connecting plate 44 and the third connecting plate 52 will be in a horizontal arrangement, so that the first connecting plate 44 and the second connecting plate 50 appear between the two adjacent goods, thereby achieving the purpose of spacing between the two adjacent goods, as shown in fig. 43, and thus the spacing mechanism 25 on the conveyor belt mechanism 3 entering the goods inspection place 76 is pulled away; as shown in fig. 30, the unlocked lock mechanism 19 will restore the initial positions of the first stopper 53 and the second stopper 56 under the restoring force of the third spring 58, and the stopper groove 54 formed by the first stopper 53 and the second stopper 56 will also restore the initial positions at this time; when the goods enter the goods inspection place 76, the inspection device 5 is provided with an X-ray generator, an image system and an alarm system to inspect the goods, and the goods move to the goods taking place 77 under the transportation action of the conveyor belt mechanism 3, as shown in FIG. 15, the limiting plate 22 limits the movement of the goods, and the limiting plate 22 is provided with the through hole 23 for facilitating the L-shaped protection plate 33 to move smoothly through the limiting plate 22; the limit plate 22 will limit the goods to move further toward the front conveyor mechanism 3, and the goods will be arranged next to each other again, and the conveyor mechanism 3 in the process will not make the first connecting plate 44 and the third connecting plate 52 merge together under the restoring force of the spiral spring 59 under the action of the pressing mechanism 7 and the accelerating device 4;

as shown in fig. 16 and 17, when passing through the conveyor belt mechanism 3 of the pressing mechanism 7, the third driving device 26 will drive the pressing friction wheel 30 to make a rotational motion, and the pressing friction wheel 30 will drive the second connecting plate 50, the third connecting plate 52, and the first connecting plate 44 to move; since the upper end surfaces of the first connecting plate 44 and the third connecting plate 52 are not in a horizontal state when the first connecting plate 44 and the third connecting plate 52 are completely unfolded, the first spring 28 is in a compressed state at the initial state, as shown in fig. 18, 19 and 20, so as to ensure that the pressing friction wheel 30 mounted on the third driving device 26 can move along the first T-shaped slot 31 opened on the first fixed block 27, so that the pressing friction wheel 30 can always drive the second connecting plate 50, the third connecting plate 52 and the first connecting plate 44 to move, and the conveyor belt mechanism 3 at the pressing mechanism 7 and the accelerating device 4 can be kept in a horizontal and straight state; as shown in fig. 43, the conveyor belt mechanism 3 will move to the locking mechanism 8; the upper lock block 37 of the upper lock mechanism 8 will contact and cooperate with the L-shaped protection plate 33 installed on the second connection block, and at the same time, the L-shaped protection plate 33 will wrap the first L-shaped moving strip 65 of the first L-shaped moving strip 65, so that the conveyor belt mechanism 3 will move under the driving device 2 at this time, but at this time, the upper lock block 37 will limit the movement of the L-shaped protection plate 33, so that the third connection plate 52 and the first connection plate 44 will move under the restoring force of the volute spiral spring 59 and the combined action of the driving device 2, so that the mounting block 43 installed on the first connection plate 44 will drive the catch 47 installed on the mounting block to move, as shown in fig. 26 and 27, the catch 47 at this time will push the first stopper 53 and the second stopper 56 to move under the action of the push inclined plane 55, and at this time, the first stopper 53 and the second stopper 56 will move relatively, so that the latch 47 can move again into the limiting groove 54 formed by the first limiting block 53 and the second limiting block 56, so that the first limiting block 53 and the second limiting block 56 can limit the movement of the latch 47, so that the first connecting plate 44 and the second connecting plate 50 can be connected again, because the elastic coefficient of the third spring 58 is smaller than that of the second spring 35; as shown in fig. 21, 22 and 23, the L-shaped protection plate 33 will push the upper locking inclined surface 40 of the upper locking block 37 to move along the guiding groove 38 opened on the second fixing block 34, so that the L-shaped protection plate 33 can smoothly cross over the upper locking block 37; the conveyor mechanism 3 entering the hold-down mechanism 7 will cause the conveyor mechanism 3 to enter the pull conveyor 78; the conveyor belt mechanism 3 entering the locking mechanism 8 will make the conveyor belt mechanism 3 enter the conveyor belt locking position 79, and then the conveyor belt mechanism 3 will make the conveyor belt mechanism 3 enter the conveyor belt cleaning position 80, so that the workers can clean the sundries on the conveyor belt mechanism 3, and the equipment of the invention finishes a transportation inspection of goods.
