As shown in fig. 1 to 4, the object falling prevention transport frame for the tail end of the belt conveyor with the multi-layer discharge port comprises a moving frame plate 1, four universal wheels 14 capable of adjusting steering are arranged on the periphery of the bottom of the moving frame plate 1, two bearing frame bodies arranged in the front-back direction are symmetrically arranged on the moving frame plate 1 in the left-right direction, two bearing plates 2 are sequentially welded between the two bearing frame bodies and in the vertical direction, and the bearing frame bodies are divided into three layers through the two bearing plates 2; each bearing frame body consists of two hollow frame bodies 4 which are symmetrically distributed on the movable frame plate 1 from front to back and a protection roller 5 which is horizontally distributed between the two hollow frame bodies 4 from front to back, and six protection rollers 5 are sequentially distributed in each bearing frame body from top to bottom; i.e. each layer of the carrier body is divided into two guard rollers 5. The hollow support body 4 of front side, the hollow support body 4 of rear side in two bear the support body on correspond to be equipped with two sets of pin subassemblies that are used for preventing the object from dropping from loading board 2 front and back side, the inside of each hollow support body 4 all is equipped with and is connected the drive arrangement who is used for driving pin subassembly mutual rotation block with the pin subassembly, it is equipped with the servo motor 3 who is connected for its power take off that provides with drive arrangement to remove frame plate 1 bottom.

As shown in fig. 1 and 2, each group of stop lever assemblies includes a first rotary stop lever 6 disposed on the left hollow frame body 4 and a second rotary stop lever 7 disposed on the right hollow frame body 4, the rotary shafts of the first rotary stop lever 6 and the second rotary stop lever 7 are coaxially connected with the driving device, and the end portions of the first rotary stop lever 6 and the second rotary stop lever 7 are provided with a protrusion 61 and a clamping groove 71 which are mutually matched and clamped; wherein, each layer of bearing frame body is distributed with a first rotary stop lever 6 and a second rotary stop lever 7.

Based on the above, protruding 61 and draw-in groove 71's design has further strengthened the intensity that rotates pin 6 and No. two and rotate pin 7, prevents because of it blocks the dynamics undersize, and the object is great because of rocking the skew dynamics in the transportation, and breaks through the blockking of a rotation pin 6 and No. two rotation pins 7, causes the object to drop.

As shown in fig. 3 and 4, the driving device includes twelve first pulleys 8 disposed in four hollow frame bodies 4 and coaxially connected with six first rotation blocking rods 6 and six second rotation blocking rods 7, a tensioning wheel 81 is sequentially and correspondingly disposed between the first pulleys 8, a mounting plate 13 is symmetrically welded at the bottom of the movable frame plate 1, four second pulleys 9 are correspondingly mounted on the front and rear mounting plates 13 through bearing seats, the four second pulleys 9 are respectively and correspondingly distributed below the four hollow frame bodies 4, a tensioning wheel 81 is also disposed between the four second pulleys 9 and the corresponding nearest first pulley 8, each second pulley 9 passes through the tensioning wheel 81 through a belt 10 to be connected with the corresponding three first pulleys 8 to form a complete belt pulley assembly, wherein the second pulleys 9 which are symmetrically distributed left and right are connected through a cross belt 11, two second belt wheels 9 which are distributed on the front and back of the right side are coaxially connected through a long shaft 12, and the servo motor 3 is fixedly arranged on a mounting plate 13 on the front side and is coaxially connected with the long shaft 12.

Based on the above, through the setting of crossing area 11 and major axis 12, servo motor 3 can drive four No. two band pulleys 9 and rotate simultaneously, sets up a rotation pin 6 on hollow support body 4 promptly, No. two rotation pin 7 can realize the block in step and keep off the material or open and get the material.

The plurality of conveying frames are arranged at the tail end of the belt conveyor with the multi-layer discharge ports and are arranged along the front-back direction; when the transportation frame is used specifically, as shown in fig. 5, the transportation frame is moved to the tail end of the multi-layer discharge port belt conveyor, so that the right side of the transportation frame is close to the discharge port of the multi-layer discharge port belt conveyor, the first layer discharge port of the multi-layer discharge port belt conveyor corresponds to the movable frame plate 1, the second layer discharge port corresponds to the first layer bearing plate 2, and the third layer discharge port corresponds to the second layer bearing plate 2. After the object on the three-layer discharge port falls to the corresponding placing position on the transportation frame, the servo motor 3 is started to drive the long shaft 12 to rotate, four second belt wheels 9 drive three first belt wheels 8 which are respectively correspondingly connected to rotate through the second belt wheels 9 and the cross belts 11, the first rotating stop lever 6 and the second rotating stop lever 7 on the three-layer bearing frame body rotate simultaneously, and the protrusions 61 and the clamping grooves 71 which correspond to the end parts of the three rotating stop levers are clamped. After the anti-dropping action is completed, the transportation frame is moved away, the transportation frame arranged in sequence is moved to the tail end of the multi-layer discharge port belt conveyor, and the process is repeated.
