[0039] In addition, the first transmission link 3a includes a plurality of first sprockets 41 distributed in a matrix along the height direction of the bracket 1 and a first chain 411 wound around the first sprocket 41 and coordinated with the first sprocket 41; among the plurality of first sprockets 41, one first sprocket 41 is connected to the action source 6 as a main sprocket, another first sprocket 41 is used as a transmission sprocket to guide the first chain 411 to move upward, and the remaining first sprockets 41 are used as guide sprockets to guide the first chain 411 to move back to the main sprocket.

[0040] The second transmission link 3b includes a plurality of second sprockets 42 distributed in a matrix at positions corresponding to the first sprocket 41 along the height direction of the bracket 1, and a second chain 421 wound around the second sprocket 42 and coordinated with the second sprocket 42; the plurality of second sprockets 42 are rotatably sleeved on the sub-bracket 10 connected to the bracket 1, and the second chain 421 and the first chain 411 are kept flush in the horizontal projection direction at positions corresponding to the first transmission path 31 and the second transmission path 32, and the second chain 421 and the first chain 411 are kept parallel in the vertical projection direction at positions corresponding to the third transmission path 33 and the fourth transmission path 34.

[0041] In addition, the picking mechanism 2 is connected to the first transmission link 3a and the second transmission link 3b through a horizontal component, so that the picking mechanism 2 remains in a horizontal state during the transmission process.

[0042] Specifically, the horizontal component includes a first connecting plate 61 arranged on the first chain 411, and a second connecting plate 62 arranged at a position corresponding to the first connecting plate 61 on the second chain 421, a first bearing 63 is embedded in the first connecting plate 61, and a first connecting rod 64 is passed through the first bearing 63; a second bearing 65 is embedded in the second connecting plate 62, and a second connecting rod 66 is passed through the second bearing 65, the protruding end on one side of the second connecting rod 66 is connected to one side of the transmission rod 7, and the protruding end on the other side of the second connecting rod 66 is connected to the picking rod 21, and the other side of the transmission rod 7 is connected to the protruding end of the first connecting rod 64.

[0043] The operating principle of this utility model is as follows:

[0044] like Figure 1 and Figure 5 As shown, first, the carrier 5 is provided with a number of carrier rods 51 extending horizontally and spaced apart from each other, and a picking channel 511 is formed between every two adjacent carrier rods 51, which opens toward the bracket 1 and passes through along the height direction; support plates 52 extending in the same direction are provided at positions corresponding to the carrier rods 51 on the carrier 5, and a fixing plate 53 is provided at the protruding end of the support plate 52, and a fixing rod 54 is connected between the fixing plate 53 and the carrier 5, and the carrier rod 51 is rotatably sleeved on the fixing rod 54; in this way, the material only needs to be moved onto the carrier rod 51, and the material can be easily moved into the range of the cyclic movement of the picking mechanism by relying on the rotation of the carrier rod 51.

[0045] Then, a first transmission link 3a is set on the bracket 1, including four first sprockets 41 distributed in a matrix along the height direction of the bracket 1 and a first chain 411 wound around the first sprockets 41 and cooperating with the first sprockets 41; one of the first sprockets 41 is connected to the action source 6 as a main sprocket, another first sprocket 41 is used as a transmission sprocket to guide the first chain 411 to move upward, and the remaining two first sprockets 41 are used as guide sprockets to guide the first chain 411 back to the main sprocket (such as Figure 1 and Figure 3 shown).

[0046] At the same time, the bracket 1 is connected to a sub-bracket 10, and a second transmission link 3b is provided on the sub-bracket 10, including four second sprockets 42 distributed in a matrix at positions corresponding to the first sprocket 41 along the height direction of the bracket 1, and a second chain 421 wound around the second sprocket 42 and in transmission cooperation with it. The four second sprockets 42 are all rotatably sleeved on the sub-bracket 10; in particular, the second chain 421 and the first chain 411 are kept flush in the horizontal projection direction at positions corresponding to the first transmission path 31 and the second transmission path 32, and the second chain 421 and the first chain 411 are kept parallel in the vertical projection direction at positions corresponding to the third transmission path 33 and the fourth transmission path 34 (such as Figure 3 and Figure 4 shown).

[0047] The first transmission link 3a and the second transmission link 3b both include a first transmission branch distributed along the height direction of the bracket 1, a second transmission branch arranged parallel to the first transmission branch, a third transmission branch connected between the lower ends of the first transmission branch and the second transmission branch, and a fourth transmission branch connected between the lower ends of the first transmission branch and the second transmission branch; the first transmission branch of the first transmission link 3a and the second transmission link 3b constitute a first transmission path 31, the second transmission branch of the first transmission link 3a and the second transmission link 3b constitute a second transmission path 32, the third transmission branch of the first transmission link 3a and the second transmission link 3b constitute a third transmission path 33, and the fourth transmission branch of the first transmission link 3a and the second transmission link 3b constitute a fourth transmission path 34.

[0048] In addition, if Figure 1 and Figure 2As shown, a horizontal component is further provided between the first transmission link 3a and the second transmission link 3b to keep the object-picking mechanism 2 in a horizontal state during the transmission process. The horizontal component includes a first connecting plate 61 provided on the first chain 411, and a second connecting plate 62 provided at a position corresponding to the first connecting plate 61 on the second chain 421. A first bearing 63 is embedded in the first connecting plate 61, and a first connecting rod 64 is passed through the first bearing 63; a second bearing 65 is embedded in the second connecting plate 62, and a second connecting rod 66 is passed through the second bearing 65. The protruding end of one side of the second connecting rod 66 is connected to the transmission rod 7, the protruding end of the other side of the second connecting rod 66 is connected to the picking rod 21, and the other side of the transmission rod 7 is connected to the protruding end of the first connecting rod 64; in this way, at the position where the first chain and the second chain turn at the same time, the first connecting plate 61 and the second connecting plate 62 turn synchronously therewith, but the first connecting rod 64 and the second connecting rod 66, under the action of the gravity of the material, combined with the first bearing 63 and the second bearing 65 respectively provided, will not turn synchronously with the first connecting plate 61 and the second connecting plate 62, but will continue to maintain the horizontal state of the picking rod 21, that is, keep the material in a horizontal state at all times when turning in space, so as to ensure the transportation stability of the material.

[0049] When in use, start the action source 6, which is set as a power motor. When the action source 6 is driven by the horizontal component to move the picking rod 21 in a counterclockwise direction to the position directly below the carrier 5 (that is, the third transmission channel 33 position), each picking rod 21 is arranged opposite to the corresponding picking channel 511, so that it can be guided by the first sprocket 41 serving as a transmission sprocket, and move upward together with the first chain 411 and the second chain 421 and pass through the picking channel 511, thereby carrying and taking away the objects on the carrier 5. The rising materials then pass through the second transmission channel 32, the fourth transmission channel 34 and the first transmission channel 31 in turn to reach any predetermined transfer position at the high end and complete the material picking operation; after taking off the materials, the picking rod 21 moves downward along the first transmission channel 31 with the horizontal component and moves to the third transmission channel 33 position, repeating the aforementioned related usage steps to achieve automatic transfer of materials to the predetermined position during the circular rotation, reducing manual labor intensity, improving transfer efficiency, and ensuring transfer stability.

[0050] In addition, the principle of circular transmission of the four transmission channels can also be used to transfer materials from a high place to a low place. At this time, it is necessary to start the action source 6 to rotate in the opposite direction of this embodiment, that is, Figure 2The clockwise rotation in the shown state places the material at a high place on the picking rod 21, and moves down along the second transmission path 32 to the position of the carrying rod 51. The picking rod 21 continues to move down through the picking channel 511 and turns to the third transmission path 33. The material is retained on the carrying rod 51 at the same time, and the material is pushed to be collected on the rotating carrying rod 51. The picking rod 21 then moves up through the first transmission path 31 to the fourth transmission path 34 to continue to pick up the material, thus realizing a circular transportation process from high to low.

[0051] The number of the first sprocket 41 and the second sprocket 42 provided in this embodiment is not unique and should be adapted and provided according to specific usage requirements, thereby generating a corresponding transfer transmission path.

[0052] It should be noted that the storage rack 5 needs to be fixedly supported on the ground. In order to simplify the schematic diagram and clearly show the structure of the use position, the diagram only shows the structural style of the storage rack 5 in the use position, and the corresponding supporting components are not marked.
