DETAILED DESCRIPTION

[0028] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] refer to Figures 1 to 11 : A logistics cargo transfer conveying device, including a frame 1, a horizontal conveying mechanism, a lifting mechanism, a loading mechanism, a feeding unit and a unloading mechanism, the horizontal conveying mechanism includes a plurality of transmission rails 7 fixedly arranged on the frame 1 at equal intervals along the height direction, the loading mechanism includes a loading output end, the lifting mechanism includes an elevator 2 symmetrically arranged at both ends of the frame 1, the conveying unit includes a transmission mechanism and a plurality of carrying trolleys 8 arranged on the transmission rails 7, each carrying trolley 8 is provided with a carrying conveyor belt 14 for conveying materials, the unloading mechanism includes a placement rack 27 fixedly arranged on one side of the frame 1, two support pipes 33 symmetrically arranged on one side of the placement rack 27, a plurality of rectangular receiving frames 28 evenly distributed on the placement rack 27 and a unloading conveying end arranged on the support pipe 33, the transmission mechanism is used to make the loading output end of the loading mechanism drive the carrying conveyor belt 14 to rotate for loading and make the unloading conveying end of the unloading mechanism drive the carrying conveyor belt 14 to rotate for unloading.

[0030] When the device is in operation, the transmission track 7 drives the carrying trolley 8 to move horizontally, and then the transmission mechanism makes the carrying trolley 8 approach the feeding output end of the feeding mechanism, and then the material is transported from the feeding output end of the feeding mechanism to the carrying conveyor belt 14, and the loading is completed. Then the transmission track 7 drives the carrying trolley 8 to move, and cooperates with the elevator 2 to make the carrying trolley 8 reach the designated receiving frame 28. It should be noted that the elevator 2 and the transmission track 7 are both controlled by the controller. The transmission track 7 drives the carrying trolley 8 to move horizontally, and the elevator 2 drives the carrying trolley 8 to move up and down. In the process of the trolley reaching the receiving frame 28, the transmission mechanism causes the carrying trolley 8 to approach the unloading conveying end of the unloading mechanism, and then the unloading conveying end drives the carrying conveyor belt 14 to move, so that the material on the carrying conveyor belt 14 moves until it falls into the receiving frame 28. In this embodiment, the transmission track 7 is an electric slide rail, and the transport trolley 8 is connected to the movable end of the electric slide block. The electric guide rail may not be provided, and the transport trolley 8 is relied on to push other transport trolleys 8 to move.

[0031] The elevator 2 is located on both sides of the transmission rail 7. A pushing cylinder is correspondingly arranged on the side of each elevator 2. The pushing cylinder corresponds to the transmission rail 7 one by one. The transmission rail 7 transports the transport trolley 8 to the elevator 2 at the corresponding end. At this time, the elevator 2 can drive the transport trolley 8 to rise and fall, so that the transport trolley 8 is aligned with other transmission rails 7. At this time, the corresponding pushing cylinder is activated and pushes the transport trolley 8 to the corresponding transmission rail 7.

[0032] In order to show the detailed structure of the feeding mechanism, the following features are also set:

[0033] The feeding mechanism includes an operating table 3 fixedly arranged on the side of the frame 1 away from the placement rack 27, a feeding conveyor belt 5 fixedly arranged on the operating table 3 and a driving motor 6 for driving the feeding conveyor belt 5. The feeding conveyor belt 5 is the feeding output end of the feeding mechanism.

[0034] When the device is running, the driving motor 6 drives the loading conveyor belt 5 to transport materials. When loading, the carrying trolley 8 is driven by the transmission mechanism to approach the loading conveyor belt 5. Then, when the loading conveyor belt 5 is running, the carrying conveyor belt 14 is also driven to run until the material is transported to the carrying conveyor belt 14.

[0035] In order to show the detailed structure of the transport vehicle 8, the following features are also specifically provided:

[0036] Each transport trolley 8 includes a supporting base plate 9, a limiting frame 10 symmetrically arranged on both sides of the top of the supporting base plate 9, a sliding block 12 elastically slidably arranged on the limiting frame 10, a mounting plate 15 fixedly arranged on the sliding block 12 and a mounting frame 16 symmetrically arranged on both sides of the top of the mounting plate 15, a transport conveyor belt 14 is arranged between the two mounting frames 16, and the supporting base plate 9 is provided with walking wheels for the transmission track 7 to drive the supporting base plate 9 to move horizontally.

[0037] In order to show the connection relationship between the sliding block 12 and the limiting frame 10, the following features are also specifically provided:

[0038] Each limiting frame 10 is provided with a transverse slideway 11 , and two sliding blocks 12 are respectively slidably matched with the transverse slideway 11 on the corresponding side.

[0039] When the carrying trolley 8 is driven by the transmission mechanism to approach the loading conveyor belt 5, the sliding block 12 drives the mounting plate 15 to move in the transverse slide 11, so that the carrying conveyor belt 14 can approach the loading conveyor belt 5, making it convenient for materials to move from the loading conveyor belt 5 to the carrying conveyor belt 14.

[0040] In order to demonstrate the elastic connection of the sliding block 12, the following features are also specifically provided:

[0041] Two damping elastic rods 13 are symmetrically arranged on both sides of each sliding block 12 , and the damping elastic rods 13 are fixedly connected to the supporting base plate 9 .

[0042] During the operation of the device, the damping elastic rod 13 can promptly drive the sliding block 12 to reset after the sliding block 12 is displaced, and when the transmission track 7 drives the supporting base plate 9 to move, the setting of the damping elastic rod 13 can also effectively reduce resonance, making the material more stable during transportation.

[0043] In order to show the detailed structure of the transmission mechanism, the following features are also set:

[0044] The transmission mechanism includes a transmission shaft 17 rotatably arranged at both ends of the mounting plate 15, two limit brackets 18 symmetrically arranged on both sides of the bottom of the mounting plate 15, a transmission shaft 19 rotatably arranged on the limit bracket 18, a transfer shaft 21 rotatably arranged next to the transmission shaft 19, a transmission gear 20 coaxially fixedly arranged on the transmission shaft 19, and a transfer gear 22 coaxially fixedly arranged on the transfer shaft 21. Two limit brackets 18 are arranged at both ends of the mounting plate 15. The transmission gears 20 at both ends can be respectively connected to the feeding output end of the feeding mechanism and the unloading conveying end of the unloading mechanism. The transmission gear 20 is meshed with the transfer gear 22. Pulleys are fixedly connected to the transfer gear 22 and the transmission shaft 17, and the two pulleys are connected by a belt. Pulleys are fixedly installed at both ends of the transmission shaft 17 and the two ends of the roller carrying the conveyor belt 14, and the pulleys at the ends of the transmission shaft 17 are connected to the pulleys at the corresponding ends of the roller carrying the conveyor belt 14 by belts.

[0045] When the carrying conveyor belt 14 is driven by the transmission mechanism to approach the loading conveyor belt 5, the transmission gear 20 is driven to rotate by the loading conveyor belt 5, and after the reversing transmission of the transfer gear 22, it finally drives the transmission shaft 17 to rotate, so that the direction of the transmission shaft 17 is consistent with the direction of the loading conveyor belt 5, so that the conveying direction of the carrying conveyor belt 14 is consistent with the conveying direction of the loading conveyor belt 5.

[0046] In order to show the connection relationship between the transfer gear 22 and the feeding conveyor belt 5, the following features are also specifically provided:

[0047] The transmission mechanism also includes wheel frames 23 arranged at both ends of the mounting plate 15, and two wheel frames 23 are symmetrically arranged on both sides of each end of the mounting plate 15. A resistance roller 24 is rotatably arranged on each wheel frame 23. A first guide plate 25 is fixedly arranged on the transmission track 7 at the bottom layer, and a first transmission tooth tube 4 is rotatably arranged on the operating table 3. Pulleys are installed at both ends of the first transmission tooth tube 4 and both ends of the roller of the feeding conveyor belt 5. The pulley at the end of the first transmission tooth tube 4 is connected to the pulley at the corresponding end of the roller of the feeding conveyor belt 5 by a belt.

[0048] When the supporting base plate 9 is driven by the driving track 7 to move, the abutting roller 24 abuts against the first guide plate 25, so that the damping elastic rod 13 away from the first guide plate 25 is compressed. Figure 4 As shown, the mounting plate 15 is caused to move laterally, so that the carrying conveyor belt 14 is close to the feeding conveyor belt 5. During this process, the transmission gear 20 is meshed with the first transmission gear tube 4, as shown in FIG. Figure 5As shown, when the loading conveyor belt 5 is running, it is transmitted through the first transmission tooth tube 4, the transmission gear 20, the transfer gear 22 and the transmission shaft 17, and finally drives the carrying conveyor belt 14 to move. When the loading is completed, the transmission track 7 continues to move with the supporting base plate 9, and then the damping elastic rod 13 elastically resets, causing the sliding block 12 to reset, and the transmission gear 20 is no longer engaged with the first transmission tooth tube 4.

[0049] In order to show the connection relationship between the transfer gear 22 and the unloading conveying end of the unloading mechanism, the following features are also specifically set:

[0050] A second guide plate 26 is fixedly provided on one side of each transmission track 7 away from the placement rack 27. The unloading mechanism also includes a plurality of adapter racks 29 evenly distributed along the length direction of the support tube 33, a second transmission tooth tube 32 rotatably provided on each adapter rack 29, and a power motor 31 fixedly provided on the adapter rack 29. One end of each second transmission tooth tube 32 is coaxially fixedly connected to a rotating output shaft of a power motor 31. A plurality of unloading guide plates 30 are evenly spaced on each adapter rack 29. Each unloading guide plate 30 corresponds to a receiving frame 28. The second transmission tooth tube 32 is the unloading conveying end of the unloading mechanism. The unloading guide plate 30 is gradually inclined downward in the direction close to the receiving frame 28.

[0051] When the transmission track 7 drives the supporting base plate 9 to move to the second guide plate 26, the contact roller 24 contacts the second guide plate 26, so that the damping elastic rod 13 away from the second guide plate 26 is compressed, causing the mounting plate 15 to move laterally, so that the carrying conveyor belt 14 is close to the unloading guide plate 30. During this process, the transmission gear 20 is engaged with the second transmission tooth tube 32, and then the power motor 31 runs to drive the second transmission tooth tube 32 to rotate, which is transmitted through the first transmission tooth tube 4, the transmission gear 20, the transfer gear 22 and the transmission shaft 17, and finally drives the carrying conveyor belt 14 to move. After the unloading is completed, the transmission track 7 continues to move with the supporting base plate 9, and then the damping elastic rod 13 is elastically reset, causing the sliding block 12 to reset, and the transmission gear 20 is no longer engaged with the second transmission tooth tube 32.

[0052] The working principle of the device is as follows: when transporting materials, the transmission track 7 first drives the carrying trolley 8 to the loading conveyor belt 5. During this process, the friction roller 24 conflicts with the first guide plate 25, so that the damping elastic rod 13 away from the first guide plate 25 is compressed, causing the mounting plate 15 to move laterally, so that the carrying conveyor belt 14 is close to the loading conveyor belt 5. During this process, the transmission gear 20 is meshed with the first transmission tooth tube 4. After that, when the loading conveyor belt 5 is running, it is transmitted through the first transmission tooth tube 4, the transmission gear 20, the transfer gear 22 and the transmission shaft 17, and finally drives the carrying conveyor belt 14 to move. When the loading is completed, the transmission track 7 continues to move with the supporting bottom plate 9, and then the damping elastic rod 13 is elastically reset, causing the sliding block 12 to reset, and the transmission gear 20 is no longer meshed with the first transmission tooth tube 4. Then the carrying trolley 8 is transported to the designated material receiving frame 28 through the cooperation of the transmission track 7 and the elevator 2. During this process, the contact roller 24 contacts the second guide plate 26, so that the damping elastic rod 13 away from the second guide plate 26 is compressed, causing the mounting plate 15 to move laterally, so that the carrying conveyor belt 14 is close to the unloading guide plate 30. During this process, the transmission gear 20 is meshed with the second transmission tooth tube 32. Then, when the power motor 31 runs, the second transmission tooth tube 32 is driven to rotate, and the transmission is transmitted through the first transmission tooth tube 4, the transmission gear 20, the transfer gear 22 and the transmission shaft 17, and finally the carrying conveyor belt 14 is driven to move. After unloading is completed, the transmission track 7 continues to move with the supporting bottom plate 9, and then the damping elastic rod 13 is elastically reset, causing the sliding block 12 to reset, and the transmission gear 20 is no longer meshed with the second transmission tooth tube 32. After that, the transmission track 7 drives the carrying trolley 8 that has completed unloading to return to the loading conveyor belt 5 for loading, and then repeats the above steps to complete the transfer and transportation of materials.

[0053] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
