In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0028] The blocking mechanism disclosed by the utility model is described below in conjunction with the accompanying drawings. Figure 1 As shown, it includes a plurality of groups of telescopic rods 100 arranged side by side, each telescopic rod 100 extends in a vertical direction, the lower ends of each group of telescopic rods 100 are connected by connecting plates 200, each connecting plate 200 is connected to a conveyor belt 300, each conveyor belt 300 is sleeved on a first transmission wheel 400 and a second transmission wheel 500, the first transmission wheel 400 and the second transmission wheel 500 are distributed along the axis of the telescopic rod 100, the axes of the first transmission wheel 400 and the second transmission wheel 500 are perpendicular to the axis of the telescopic rod 100, the first transmission wheel 400 is rotatably arranged on a wheel seat 600, and several second transmission wheels 500 are concentrically arranged on the same connecting shaft 700, and the two ends of the connecting shaft 700 are rotatably arranged on a support 800 and connected to a No. 1 motor 900 that drives the connection shaft 700 to rotate. Of course, the first transmission wheel can also be connected to the connecting shaft 700.

[0029] The number of groups of the telescopic rods 100 can be designed as needed. In the present embodiment, the telescopic rods 100 are divided into two groups, each group of telescopic rods 100 includes two telescopic rods, each telescopic rod 100 is inserted into two guide sleeves, each guide sleeve is fixed on a fixed plate, and the two guide sleeves corresponding to the position of each group of telescopic rods 100 are located on the same fixed plate, and the position of the fixed plate is fixed.

The motor frame 001 is provided with a strip-shaped connecting hole 003 extending along the axis of the telescopic shaft by a predetermined length. The motor frame 001 is fixed to other structures by bolts passing through the strip-shaped connecting hole 003. Since the motor frame 001 can move along the strip-shaped connecting hole 003 and the motor frame 001 is located above the connecting shaft 700, the motor frame 001 will move downward due to the pulling force of the belt. In view of this, in order to prevent the motor frame 001 from moving downward and causing the belt to loosen and affect the transmission, a limit plate 004 is provided on the motor frame 001. The limit plate 004 is located below the strip connecting hole 003 and is provided with a screw hole 005. The axis of the screw hole 005 is parallel to the axis of the telescopic rod 100. A bolt is screwed in the screw hole 005 and abuts against a fixed position, thereby effectively providing support for the motor frame 001 and preventing the motor frame 001 from moving downward.

[0031] As attached Figure 1 , Attachment Figure 2 As shown, in order to accurately determine whether the telescopic rod is extended and retracted to the position, a trigger member 006 is provided at the outer end of each connecting plate 200, and a lower sensor 007 and an upper sensor 008 are provided on the outer side of the end of the connecting plate 200.

The strip mounting holes 010 are two in number. The lower sensor 007 and the upper sensor are connected to the mounting frame 009 by an L-shaped connecting member screwed at the strip mounting hole 010.

[0034] As attached Figure 2 -Attached Figure 4 As shown, the conveying assembly A includes a bracket A10, on which three conveying modules A20 are arranged at equal intervals. Each conveying module A20 can be a belt conveying module or a chain conveying module. The chain conveying module is taken as an example for explanation, and includes a support frame A21 fixed on the bracket A10, and end sprockets A22 are rotatably provided at both ends of the support frame A21, and chains A23 are mounted on the two end sprockets A22, and the chain A23 is also engaged with a driving sprocket A25 located on the inner side thereof.

The steering sprockets are located above both sides of the driving sprocket and are rotatably arranged in the axle seat A24. The two steering sprockets make the chain A23 between the end plate sprocket and the tensioning sprocket parallel to the chain A23 between the end sprockets A22.

At the same time, the other end of the conveying assembly A is provided with a blocking column C located between adjacent conveying modules A20. When the goods are located on the conveying assembly A, the blocking structure and the blocking column C can limit the position of the goods to prevent the goods from falling from the conveying assembly A.
