[0023] Example:

[0024] In view of the chain conveyor equipment currently commonly used in the automated warehousing and logistics industry, due to the structural design problems of the conveyor itself, the cargo loading and unloading docking needs to cooperate with other mechanical equipment (such as: jacking machine) to operate, which makes the structure of the chain conveyor more complicated and the cargo loading and unloading process more troublesome. We have designed a chain conveying mechanism that can be perfectly combined with forklift operations. The specific plan is as follows:

[0025] like Figure 1-3 As shown, the utility model discloses a PD station type chain conveying mechanism, including a main frame 1, a driving motor 2 and a driving shaft 3 are installed inside the main frame 1, both ends of the driving shaft 3 are rotatably installed with the main frame 1 through seat bearings, a driving gear 5 and a plurality of transmission gears 4 are installed on the driving shaft 3, the driving shaft 3 and the driving motor 2 are rotatably connected through the cooperation of the driving gear 5 and the driving chain 6, and a plurality of material conveying components are also provided on the main frame 1 along the length direction of the main frame 1.

[0026] Among them, the material conveying component includes a number of long grooved wheel seats 8 installed at equal distances from left to right on the top of the main frame 1, and a rotatable No. 1 guide gear 9 is installed at both ends of each wheel seat 8. The position of each transmission gear 4 on the drive shaft 3 corresponds to the upper and lower positions of a wheel seat 8, and two tension gears 10 are rotatably installed at the bottom of each wheel seat 8.

[0027] like Figure 1-3 As shown, the material conveying assembly also includes a load-bearing frame 11 installed at the front end of the main frame 1 corresponding to the end position of each wheel seat 8, and an opening 12 for the chain to pass through is provided at both ends and the middle of the load-bearing frame 11, and a vertical frame 13 is installed on the opening 12 located in the middle of the load-bearing frame 11 and at one end away from the wheel seat 8. The top of the vertical frame 13 adopts a horizontal design. At the same time, the top of the load-bearing frame 11 is constructed through the vertical frame 13 to form a forklift arm slot 14 for convenient forklifts to load and unload goods. Furthermore, an upper transition gear 15 is installed on both sides of the top of each vertical frame 13, and a lower transition gear 17 is rotatably installed on the inner side of the load-bearing frame 11 and corresponding to the top position of each end of the opening 12, and the bottom ends of the inner side of the load-bearing frame 11 are also A No. 2 guide gear 19 is installed. Furthermore, each material conveying assembly also includes a material conveying chain 18, which is respectively meshed and transmitted with the No. 1 guide gear 9, the tension gear 10, the transmission gear 4, the lower transition gear 17, the No. 2 guide gear 19 and the upper transition gear 15 in the corresponding material conveying assembly. Under the premise of not affecting the transportation of goods, the entire conveying mechanism forms a trough body at the front end that can cooperate with a forklift, so that the forklift can directly load and unload goods from the conveyor without cooperating with the jacking machine, which can effectively simplify the cargo handling operation process, and at the same time simplify the complexity of the chain conveying mechanism, which is beneficial to improving the stability of the equipment during operation and the work efficiency of cargo transportation.

[0028] A guide plate 7 is installed on both sides of the top of the rear end of the main frame 1, and an adjusting foot is installed on each support foot at the bottom of the main frame 1. The guide plate 7 is designed mainly to guide the transportation of goods so that they can accurately enter the loading and unloading position at a specific angle. The adjusting foot is mainly used to cooperate with the bolts to adjust the ground angle and height of the equipment.

[0029] In order to ensure that the goods can be smoothly moved to the designated loading and unloading position, the height of the upper transition gears 15 at both ends of the top of each stand 13 is consistent with the height of the No. 1 guide gear 9 at both ends of the wheel seat 8.

[0030] In order to prevent the goods from falling to the ground, a movable dead stop 16 is installed at the end of each load-bearing frame 11 away from the wheel seat 8, wherein the movable dead stop 16 can be installed with an induction switch (not shown) electrically connected to the controller of the drive motor 2. When the goods are moved to the specified position, its cargo pallet comes into contact with the movable dead stop 16, the induction switch gives a signal, and the drive motor 2 stops working, so that the conveying mechanism is temporarily in a shutdown state, waiting for the loading and unloading staff to use a forklift to load and unload the goods.

[0031] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
