In summary, the present invention has the following advantages:

[0021] 1. Traditional belt conveyor mechanisms can mostly only perform single horizontal conveying or inclined conveying at a fixed angle; this solution adjusts the inclination direction and inclination angle at both ends of the first conveyor frame through the support structure, thereby adjusting the conveying height. It can also achieve various conveying states, such as straight, V-shaped or Z-shaped conveying, through the first adjustment unit, second adjustment unit and third adjustment unit; it can adapt to more complex conveying needs.

[0022] 2. Existing belt conveyor mechanisms often have limited adjustment in terms of conveying height and length, which may require replacing parts of different specifications or making complex modifications. This solution adjusts the conveying height through the support structure and adjusts the conveying length through the cooperation of the first and second adjustment units, which can better adapt to different working environments and conveying tasks.

[0023] 3. Traditional belt conveyors have difficulty adjusting the angle of the conveyor belt ends. This solution adjusts the conveyor belt angle at both ends of the first conveyor frame through the third adjustment unit to achieve the overall end level or tilt. This is very useful in some special conveying scenarios, such as when conveying goods into containers or equipment of different shapes and layouts. By adjusting the angle of the conveyor belt ends, the goods can be accurately and smoothly delivered to their destination.

[0024] 4. The conveying equipment in this solution can achieve multiple conveying states (straight line, V-shape or Z-shape), which is more versatile than the existing belt conveyor mechanism. In complex industrial production processes or logistics distribution systems, this versatility can reduce the need for multiple different types of conveying equipment, and reduce equipment procurement costs, floor space and maintenance workload.

The two ends of a pair of first shafts 66 are respectively fixedly inserted between the first bearings 12, and a pair of first belt rollers 67 are fixedly mounted on the first shafts 66. The first belt rollers 67 are respectively located between the first conveyor frames 5 and on the rear side of the lifting seat 64. The motor on the lifting seat 64 drives the first shaft 66 to rotate, causing one of the first belt rollers 67 to drive the conveyor belt 9 to rotate. The lifting seat 64 raises the compression spring 63, shortens the gap between the first belt rollers 67, and thus allows the conveyor belt 9 to grow.

[0039] As a further embodiment of the present invention, the second adjustment unit 7 includes a second conveyor frame 71, a first adapter arm 72, a first drive arm 73, a second belt roller 74, a support 75, and a first hydraulic cylinder 76; the second conveyor frame 71 is L-shaped, and one end of the second conveyor frame 71 is provided with a second slide groove 11 that fits with the first slide groove 10. The second conveyor frame 71 is movably fitted onto the bottom end of the first conveyor and located at the position of the first slide groove 10. The other end of the second conveyor frame 71 is located below the first bearing 12 and close to the lifting frame 61.

One end of each pair of third conveyor frames 81 is movably connected to the other end of the first adapter arm 72, and one end of the third conveyor frame 81 is opposite to the second conveyor frame 71, while the other end of the third conveyor frame 81 is staggered opposite to the other end of the second conveyor. The other end of the third conveyor frame 81 is also connected to the first adapter arm 72. Corresponding to the left end of the conveyor frame 5, one end of a pair of tilting frames 82 is fixedly set on the lower wall of one end of the second conveyor frame 71, and one end of a pair of second hydraulic cylinders 83 is movably connected to the other end of the tilting frame 82. The telescopic end of the second hydraulic cylinder 83 is inclinedly and movably connected to the middle of the lower wall of the third conveyor frame 81. The third belt roller 84 is movably set between the other ends of the third conveyor frame 81 through the first shaft 66 and is opposite to the first bearing 12. The telescopic movement of the second hydraulic cylinder 83 drives the third conveyor frame 81 to tilt at a certain angle on the first adapter arm 72, thereby adjusting the tilt of the conveyor belt 9 on the third belt roller 84.

[0041] As a further embodiment of the present invention, the conveyor belt 9 is movably mounted on the first belt roller 67 and the third belt roller 84 respectively, and the lower wall of the conveyor belt 9 is attached to the upper wall of the second belt roller 74 for connection design requirements.

[0042] As a further embodiment of the present invention, a pair of first belt rollers 67 and a second guide roller are arranged in a triangular region to adjust the length of the conveyor belt 9 according to the design and installation requirements.

[0043] Working principle:

[0044] When the equipment is in use, it is moved by the casters 2 on the lower wall of the base 1; after the equipment is powered on, it can be driven by the controller 3; that is, the controller 3 drives the first motor 65 in the conveying structure symmetrically set at both ends of the first conveyor frame 5 to rotate in the same direction, and then drives one of the first belt rollers 67 to rotate through the first shaft 66, and drives the conveyor belt 9 to rotate on the first belt roller 67, the second belt roller 74 and the third belt roller 84 through the first belt roller 67, so that the conveyor belt 9 can be used for horizontal conveying between the two ends of the first conveyor frame 5;

[0045] When it is necessary to adjust the height of both ends of the first conveyor frame 5 and use it for inclined conveying, the corresponding support structure 4 can be selected according to the inclination direction; by rotating the drive screw 44 on the support plate 42, the second bracket 45 is forced to move under the limit of the two sliding arms 43, which can drive the first arm 46 on the second bracket 45 to flip relative to the second arm 47 on the first bracket 41 to change the included angle. The larger the included angle between the first arm 46 and the second arm 47, the lower the support height of the fixed frame 48; conversely, the smaller the included angle between the second arm 47 and the first arm 46, the higher the support height of the fixed frame 48.

[0046] As the height of the fixed frame 48 changes, it can cause the corresponding end of the first conveyor frame 5 to rotate at a certain angle, so that the first conveyor frame 5 can be tilted as a whole, thus realizing the tilted conveying of the conveyor belt 9.

[0047] The first hydraulic cylinder 76 on the support 75 in the second adjustment unit 7 can be extended to drive the second conveyor frame 71 to slide on the first conveyor frame 5 through the engagement of the second slide groove 11 and the first slide groove 10, thereby causing the third adjustment unit 8 on one end of the second conveyor frame 71 to move away from the first conveyor frame 5, thereby increasing the length of the upper wall of the conveyor belt 9 between the first conveyor frames 5 and increasing the conveying length.

[0048] As the second conveyor frame 71 slides, the conveyor belt 9 is stretched. As the length of the conveyor belt 9 between the third belt roller 84 and the first belt roller 67 between the first bearing 12 increases, the conveyor belt 9 will exert force on the first belt roller 67 at the drive end of the first motor 65 through the guidance of the second belt roller 74. This causes the first motor 65 and the first belt roller 67 to rise and move from the bottom of the lifting frame 61 with the help of the lifting seat 64 and the limit of the sleeve rod 62. This results in a smaller gap between the two first belt rollers 67 and a shorter length of the conveyor belt 9. The shortening distance of the conveyor belt 9 between the first belt rollers 67 is the increase in length of the conveyor belt 9 between the third belt roller 84 and the first bearing 12. When the first hydraulic cylinder 76 on the support 75 retracts and drives the second conveyor frame 71 to reset, the lifting seat 64 is lowered and reset by the force of the spring 63.

[0049] By driving the second hydraulic cylinder 83 to extend and retract, since the second hydraulic cylinder 83 is movably connected to the tilting frame 82 and the third conveyor frame 81, the third conveyor frame 81 is driven to tilt upward or downward at a certain angle on the first transfer arm 72, and the second hydraulic cylinder 83 is tilted at a certain angle on the tilting frame 82; thereby achieving the tilting of the conveyor belt 9 located at the third belt roller 84 at a certain angle, realizing the tilting and height of the end of the upper wall of the overall conveyor belt 9, which can be used for the use of the equipment inlet;

[0050] In summary, the conveying length of the upper wall of the conveyor belt 9 is adjusted by the cooperation of the first adjustment unit 6 and the second adjustment unit 7; horizontal or inclined conveying can be achieved by the support structure 4, and both ends of the first conveyor frame 5 can be adjusted; by the cooperation of the support structure 4 and the third adjustment unit 8, the upper wall of the overall conveyor belt 9 can be formed into a straight line, a V-shape or a Z-shape, and when a Z-shape is formed, the first conveyor frame 5 and the second conveyor frame 71 are inclined, while the third conveyor frame 81 remains horizontal.

[0051] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
