[0027] The present invention will be further described in detail below in conjunction with the specification drawings and embodiments.

[0028] Embodiment 1

[0029] As Figures 1-5 shown, an AGV intelligent handling vehicle for improving handling efficiency includes an AGV intelligent handling vehicle body 1. An inclined unloading mechanism 2 is arranged above the AGV intelligent handling vehicle body 1. The inclined unloading mechanism 2 includes a driving column 204. A support rotating plate 205 is fixedly connected to the outer surface of the driving column 204. A goods holding hopper 3 is fixedly connected to the upper surface of the support rotating plate 205.

[0030] The outer surface of the driving column 204 is rotatably connected to the supporting inner groove plate 206. The inner wall of the supporting inner groove plate 206 is in contact with the supporting rotating plate 205. The bottom surface of the supporting inner groove plate 206 is fixedly connected to the upper surface of the AGV intelligent handling vehicle body 1. By using the supporting inner groove plate 206, the supporting rotating plate 205 can be effectively supported. The slot inside the supporting inner groove plate 206 should be preset to meet the rotation range of the supporting rotating plate 205, so that the supporting rotating plate 205 will not be interfered during rotation.

[0031] A driving transmission mechanism 4 is arranged inside the goods loading hopper 3. The driving transmission mechanism 4 includes a motor body 401 and a transmission belt 405. The output end of the motor body 401 is fixedly connected to a driving shaft 402. The outer surface of the driving shaft 402 is rotatably connected to the inner wall of the goods loading hopper 3.

And there is a large frictional force between the outer surfaces of the driving shaft 402 and the supporting shaft 404 and the inner wall of the transmission belt 405, so that the driving shaft 402 and the supporting shaft 404 can drive the transmission belt 405 to transport goods.

The inner wall of the first synchronous pulley 201 is fixedly connected to the outer surface of the driving shaft 402. The outer surface of the driving column 204 is fixedly connected to a second synchronous pulley 202. The first synchronous pulley 201 and the second synchronous pulley 202 are connected by a first synchronous belt 203. The cooperation of the first synchronous pulley 201, the second synchronous pulley 202 and the first synchronous belt 203 can transmit the kinetic energy of the driving shaft 402 to the driving column 204, making the goods in the tilting goods loading hopper 3 and the transmission goods loading hopper 3 a synchronous process.

The outer surface of the baffle door 604 is fixedly connected with an N-shaped connecting plate 603, and the outer surface of the N-shaped connecting plate 603 is fixedly connected with a center circular plate 602. When the N-shaped connecting plate 603 rotates around the center of the center circular plate 602, it can drive the baffle door 604 to open the closure of the cargo bucket 3, so that the goods can be unloaded from the side of the cargo bucket 3. The baffle door 604 is set to be a plate shorter than the diameter of the cargo bucket 3 to avoid interference during the rotation process.

[0036] The upper surface of the bevel gear 605 is fixedly connected with a linkage shaft 606, the outer surface of the linkage shaft 606 is rotatably connected to the inner top wall of the protective shell 5, the outer surface of the linkage shaft 606 is fixedly connected with a third synchronous wheel 607, the inner wall of the center circular plate 602 is fixedly connected with a vertical shaft 601, the outer surface of the vertical shaft 601 is rotatably connected to the inner top wall of the protective shell 5, the outer surface of the vertical shaft 601 is fixedly connected with a fourth synchronous wheel 608, the third synchronous wheel 607 and the fourth synchronous wheel 608 are connected by a second synchronous belt 609, and the inner top wall of the protective shell 5 can provide a support point for the linkage shaft 606 and the vertical shaft 601 when they rotate. Driven by the first bevel gear 403, the bevel gear 605 drives the third synchronous wheel 607, the second synchronous belt 609, the fourth synchronous wheel 608, the vertical shaft 601 and the center circular plate 602 to rotate in turn, so that the drive transmission mechanism 4 opens the baffle door 604 to unload while conveying the goods.

[0037] The working principle of this embodiment is as follows:

[0038] First, put the goods into the cargo bucket 3. During the transportation of the goods by the AGV intelligent transport vehicle body 1, the cargo bucket 3 and the baffle door 604 can protect the goods. After the goods are transported to the designated location, by starting the motor body 401, the driving shaft 402 and the first bevel gear 403 can be driven to rotate, and the driving shaft 402 can drive the transmission belt 405 to rotate, so that the goods can be transported. The first bevel gear 403 can also drive the bevel gear 2 605 to rotate, and the bevel gear 2 605 can drive the third synchronous wheel 607 to rotate, and the third synchronous wheel 607 can drive the second synchronous belt 609 and the fourth synchronous wheel 608 to rotate, and the fourth synchronous wheel 608 can drive the vertical shaft 601, the center circular plate 602, and the N-shaped connecting plate 603 to rotate, and the baffle door 604 can be opened.

The second synchronous wheel 202 can drive the driving column 204 and the supporting rotating plate 205 to rotate, and finally can drive the cargo bucket 3 to tilt, so as to facilitate the unloading of goods.

[0039] Example 2

[0040] The difference between this embodiment and Embodiment 1 is that when the navigation system fails during the movement of the AGV intelligent transport vehicle body 1, the AGV intelligent transport vehicle body 1 can be prevented from being damaged by foreign objects.

[0041] As Figure 6 shown, anti-collision mechanisms 7 are provided on all four sides of the AGV intelligent transport vehicle body 1. The anti-collision mechanism 7 includes an anti-collision baffle 701. A sliding column 702 is fixedly connected to the outer surface of the anti-collision baffle 701. A buffer cylinder 705 is slidably connected to the outer surface of the sliding column 702. One side surface of the buffer cylinder 705 close to the AGV intelligent transport vehicle body 1 is fixedly connected to the AGV intelligent transport vehicle body 1. One end of the sliding column 702 away from the anti-collision baffle 701 is fixedly connected to a damper 703. One end of the damper 703 away from the sliding column 702 is fixedly connected to a buffer spring 704. The buffer spring 704 is fixedly connected to the inner wall of the buffer cylinder 705. By using the synchronous action of the damper 703 and the buffer spring 704, the reaction force when the anti-collision baffle 701 touches a foreign object can be buffered, and the AGV intelligent transport vehicle body 1 can be prevented from being damaged by collision.

[0042] Two guiding columns 706 are fixedly connected to the outer surface of the anti-collision baffle 701. Guide cylinders 707 are slidably connected to the outer surfaces of the two guiding columns 706. One side surface of the two guide cylinders 707 close to the AGV intelligent transport vehicle body 1 is fixedly connected to the AGV intelligent transport vehicle body 1. Through the guiding of the guiding column 706 and the guide cylinder 707, the anti-collision baffle 701 can be prevented from tilting when it touches a foreign object.

[0043] The working principle of this embodiment is as follows: When the navigation system of the AGV intelligent transport vehicle body 1 fails, the AGV intelligent transport vehicle body 1 will move around randomly. When it hits a foreign object, first, the anti-collision baffle 701 will contact the foreign object. The anti-collision baffle 701 can drive the sliding column 702 and the damper 703 to move. The damper 703 can squeeze the buffer spring 704 to generate deformation. Under the synchronous action of the damper 703 and the buffer spring 704, the reaction force generated when the anti-collision baffle 701 collides can be buffered, so that the AGV intelligent transport vehicle body 1 can be prevented from being damaged by collision.
