A disassembly and assembly mechanism 8 is provided between the bottom frame 21 and the top frame 22. An adjustment mechanism 9 is provided on the base 1.

[0024] Specifically, by starting the transmission motor 5, the first transmission roller 3 starts to rotate under the transmission action of the first belt transmission group 6, and then under the transmission of multiple second belt transmission groups 7, multiple transmission rollers 3 rotate synchronously, and then the conveying work can begin.

[0025] Embodiment 2

[0026] See also Figure 3 and Figure 4, and on the basis of the first embodiment, it is further obtained that the disassembly and assembly mechanism 8 includes a wedge-shaped insertion plate 801 fixedly connected to the bottom of the top frame 22. A slot 803 for inserting the wedge-shaped insertion plate 801 is formed in the bottom frame 21. A storage cavity 804 is formed in the bottom frame 21. A sliding block 805 is slidably connected in the storage cavity 804. A wedge-shaped clamping block 806 is fixedly arranged at one end of the sliding block 805. A clamping slot 802 adapted to the wedge-shaped clamping block 806 is formed in the wedge-shaped insertion plate 801. The wedge-shaped clamping block 806 slidably penetrates through the storage cavity 804 and is clamped with the clamping slot 802. A connecting rod 807 is fixedly arranged at the other end of the sliding block 805. A spring 808 is sleeved on the connecting rod 807; the wedge-shaped insertion plate 801 is in extrusion sliding connection with the wedge-shaped clamping block 806. The spring 808 is fixedly arranged between the storage cavity 804 and the sliding block 805. One end of the connecting rod 807 away from the sliding block 805 slidably penetrates through the storage cavity 804 and is fixedly connected to a limiting plate 809. A pull ring 810 is fixedly arranged on the limiting plate 809.

[0027] Specifically, by pulling the pull ring 810, the connecting rod 807 drives the wedge-shaped clamping block 806 to retract into the storage cavity 804. Then, the wedge-shaped insertion plate 801 is pulled out of the slot 803, and the top frame 22 is removed from the bottom frame 21. After the transmission roller 3 is maintained or replaced, the roller shaft 31 of the transmission roller 3 is placed in the semi-circular groove 23 on the bottom frame 21. Then, the wedge-shaped insertion plate 801 on the top frame 22 is inserted into the slot 803 again. The wedge-shaped insertion plate 801 squeezes the wedge-shaped clamping block 806 to make it retract into the storage cavity 804. When the wedge-shaped insertion plate 801 is completely inserted into the slot 803, the wedge-shaped clamping block 806 automatically pops out under the elastic return of the spring 808 and is clamped with the clamping slot 802 on the wedge-shaped insertion plate 801, so that the bottom frame 21 and the top frame 22 are firmly connected.

[0028] Embodiment Three

[0029] Refer to Figure 5, and on the basis of the first and second embodiments, it is further obtained that the adjusting mechanism 9 includes two sliding grooves 901 opened on the base 1. Sliders 902 are slidably connected in both of the two sliding grooves 901. An adjusting motor 907 is fixedly arranged on the base 1. A screw rod 906 threadedly connected to the slider 902 is rotatably connected in the sliding groove 901 at one end of the base 1 close to the adjusting motor 907. One end of the screw rod 906 slidably penetrates through the sliding groove 901 and is drivingly connected to the rotating shaft of the adjusting motor 907 by a third belt transmission group 908. A hinge rod 905 is hingedly arranged between the bottom end of the chassis 21 close to the base 1 and the two sliders 902. A support leg 910 is hingedly arranged at the bottom end of the chassis 21 far from the base 1; A guide rod 909 slidably connected to the slider 902 is fixedly arranged in the sliding groove 901 at the end of the base 1 far from the adjusting motor 907. Limit blocks 903 are fixedly arranged at both ends of the slider 902. Limit grooves 904 adapted to the limit blocks 903 are opened in the sliding groove 901. The limit blocks 903 are slidably connected to the limit grooves 904.

[0030] Specifically, by starting the adjusting motor 907, the screw rod 906 is rotated under the driving action of the third belt transmission group 908. Under the threaded connection of the screw rod 906 and the slider 902, the two sliders 902 can move along the sliding groove 901. When the slider 902 moves, it can drive the hinge rod 905 to tilt. One end of the transmission frame 2 close to the hinge rod 905 can be adjusted in height according to the tilt degree of the hinge rod 905, so as to realize the adjustment of the tilt angle of the conveyor, facilitate meeting the different needs of users for transporting goods, and improve the transportation efficiency.

[0031] During the actual operation process, by starting the transmission motor 5, the first transmission roller 3 starts to rotate under the driving action of the first belt transmission group 6. Then, under the driving of a plurality of second belt transmission groups 7, the plurality of transmission rollers 3 rotate synchronously, and then the conveying work can be started;

[0032] When maintenance or replacement of the transmission roller 3 is required, first, by pulling the pull ring 810, the connecting rod 807 drives the wedge-shaped block 806 to retract into the storage cavity 804. Then, the wedge-shaped insertion plate 801 is pulled out of the slot 803, and the top frame 22 can be removed from the bottom frame 21. At this time, the roller shaft 31 of the transmission roller 3 is no longer limited and is exposed. Then, maintenance or replacement of the transmission roller 3 can be carried out. After the maintenance or replacement is completed, the roller shaft 31 of the transmission roller 3 is placed back into the semi-circular groove 23 on the bottom frame 21. Then, the wedge-shaped insertion plate 801 on the top frame 22 is inserted into the slot 803 again. The wedge-shaped insertion plate 801 squeezes the wedge-shaped block 806 to make it retract into the storage cavity 804. When the wedge-shaped insertion plate 801 is completely inserted into the slot 803, the wedge-shaped block 806 automatically pops out under the elastic return of the spring 808 and is clamped with the card slot 802 on the wedge-shaped insertion plate 801, so that the bottom frame 21 and the top frame 22 are firmly connected, completing the maintenance and replacement operation of the transmission roller 3;

[0033] When the inclination angle of the transmission frame 2 needs to be adjusted, by starting the adjustment motor 907, the screw rod 906 rotates under the driving action of the third belt transmission group 908. Under the threaded connection of the screw rod 906 and the slider 902, the two sliders 902 can move along the chute 901. When the slider 902 moves, it can drive the hinge rod 905 to incline. One end of the transmission frame 2 close to the hinge rod 905 can be adjusted in height along with the inclination of the hinge rod 905, thereby realizing the adjustment of the inclination angle of the conveyor.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
