A second lead screw 37 threadedly connected to one side of the bottom of the second fixed frame 35 is fixed at the output shaft end of the third motor 39, and the output shaft end of the third motor 39 has a brake self-locking structure. The model of the third motor 39 is: 1FL6096-1AC61-0AB1, and the output shaft of the third motor 39 drives the second lead screw 37 to rotate. At this time, the second lead screw 37 is threadedly connected to the second fixed frame 35, so that the second fixed frame 35 moves upward or downward along the slide rod 34 on the inner wall of the slide groove 33;

[0049] The inner wall of one of the slide grooves 33 is rotatably connected to the second lead screw 37 through a bearing, and the inner walls of the other three slide grooves 33 are fixed with slide rods 34 that movably penetrate one side of the bottom of the second fixed frame 35. The fixed block 24, the stopper 27 and the bottom of the second motor 29 are all fixed to the top of the cross plate 31. When the second fixed frame 35 moves upward, the conveying height of the belt 11 is in an increasing state, and when the second fixed frame 35 moves downward, the conveying height of the belt 11 is in a decreasing state.

[0050] A moving assembly 5 is provided at the lower side of the lifting assembly 3; the moving assembly 5 includes a base 51 and a bottom plate 54, a plurality of rubber bumps 6 are bonded to the bottom of the bottom plate 54, the rubber bumps 6 and the bottom plate 54 increase the contact area between the base 51 and the ground and increase the friction force, the inner wall of the base 51 is rotatably connected to two rotating shafts 52 through bearings, the outer sides of the rotating shafts 52 are respectively fixedly sleeved with a first gear 57 and a second gear 58, the push rod end of the electric cylinder 511 pushes the second gear rod 510 to extend, at this time, the second gear rod 5 10 is meshed and connected with the second gear 58, so that the second gear 58 rotates. There are two first gears 57. The inner wall of the base 51 is slidably connected with the vertical plate 56 and the third gear rod 512 through the slide rail. The bottom side of the third gear rod 512 is fixed to the top of the bottom plate 54. A plurality of universal wheels 53 are installed at the bottom of the vertical plate 56. The second gear 58 drives the rotating shaft 52 and the two first gears 57 to rotate. When the first gear 57 rotates, it is meshed and connected with the first gear rod 55 and the third gear rod 512 respectively.

[0051] Two first gear rods 55 are fixed to one side of the vertical plate 56, and the first gear rod 55 and the third gear rod 512 are both meshed and connected with the first gear 57. The first gear rod 55 and the third gear rod 512 are respectively located on both sides of the first gear 57. An electric cylinder 511 is fixed to the top of the inner wall of the base 51, and a second gear rod 510 meshed and connected to the outer side of the second gear 58 is fixed to the push rod end of the electric cylinder 511. The top of the base 51 is fixed to the bottom of the first fixed frame 32. The second gear 58 drives the rotating shaft 52 and the two first gears 57 to rotate. When the first gear 57 rotates, it is meshed and connected with the first gear rod 55 and the third gear rod 512 respectively. The first gear rod 55 drives the vertical plate 56 and the universal wheel 53 to move upward and leave the ground, so that the third gear rod 512 slides downward on the inner side of the slide rail track groove, and the third gear rod 512 pushes the bottom plate 54 and the multiple rubber protrusions 6 at the bottom thereof to contact the ground. The rubber protrusions 6 and the bottom plate 54 increase the contact area between the base 51 and the ground to increase the friction.

[0052] A battery (not shown) is installed on the top of the inner wall of the base 51. The battery is used to provide power supply for the second motor 29, the third motor 39 and the electric cylinder 511. The first motor 15 is connected to the municipal AC power supply.

[0053] Working principle: the output shaft of the first motor 15 is controlled to drive the first pulley 14 to rotate, the first pulley 14 drives the second pulley 16 to rotate through the synchronous belt, the second pulley 16 drives the rotating roller 13 to rotate, and the friction between the rotating roller 13 and the belt 11 causes the belt 11 sleeved on the outer side of the rotating roller 13 to rotate, and at this time the belt 11 can transport the goods;

[0054] When smaller goods need to be transported from a low place to a high place, at this time, it is only necessary to press the switch group to control the output shaft of the second motor 29 to drive the first screw 28 to rotate. At this time, the first screw 28 is threadedly connected to the limit rod 21, so that the limit rod 21 moves along the slide column 26 to the side of the first limit block 22. At this time, the angle between the connecting rod 23 and the horizontal plane increases, so that the first limit block 22 and the connecting rod 23 rotate around the hinge point, and the fixed block 24 and the second limit block 25 also rotate around the hinge point, so that the conveying angle of the belt 11 changes, and then the height of the belt 11 close to the first limit block 22 side increases, and the fixed block 24 and the second limit block 25 at the bottom of the other side of the belt 11 also rotate around the hinge point. At this time, the belt conveyor can transport goods from a low place to a high place;

[0055] When the height of the goods to be transported is relatively high, the output shaft of the third motor 39 is controlled to drive the second lead screw 37 to rotate. At this time, the second lead screw 37 is threadedly connected to the second fixing frame 35, so that the second fixing frame 35 moves upward or downward along the slide bar 34 on the inner wall of the slide slot 33. At the same time, the second fixing frame 35 drives the height of the top cross plate 31 and the belt 11 to change, so that the belt 11 is at different heights. At this time, goods of different heights can be transported;

[0056] When the belt conveyor needs to be moved to another position for cargo transportation, it is only necessary to control the push rod end of the electric cylinder 511 to push the second gear rod 510 out, at which time the second gear rod 510 is meshed and connected with the second gear 58, so that the second gear 58 rotates. At this time, the second gear 58 drives the rotating shaft 52 and the two first gears 57 to rotate. When the first gear 57 rotates, it is meshed and connected with the first gear rod 55 and the third gear rod 512 respectively, so that the third gear rod 512 slides upward on the inner side of the track groove of the slide rail, so that the bottom plate 54 and the rubber protrusion 6 at the bottom of the bottom of the slide rail leave the ground, and at the same time, the first gear rod 55 slides downward on the inner side of the track groove of the slide rail, and the first gear rod 55 drives the vertical plate 56 to move downward, so that the multiple universal wheels 53 at the bottom of the vertical plate 56 contact the ground. Under the action of the multiple universal wheels 53, the belt conveyor can be moved to the next working position;

[0057] When the belt conveyor needs to transport stably, it is only necessary to control the push rod end of the electric cylinder 511 to drive the second gear rod 510 to retract to its original position. At this time, the second gear rod 510 is meshed with the second gear 58, and the second gear 58 drives the rotating shaft 52 and the two first gears 57 to rotate. When the first gear 57 rotates, it is meshed with the first gear rod 55 and the third gear rod 512 respectively. The first gear rod 55 drives the vertical plate 56 and the universal wheel 53 to move upward and leave the ground, so that the third gear rod 512 slides downward on the inner side of the slide rail groove, and the third gear rod 512 pushes the bottom plate 54 and the multiple rubber protrusions 6 at the bottom thereof to contact the ground. The rubber protrusions 6 and the bottom plate 54 increase the contact area between the base 51 and the ground to increase the friction.

[0058] The present invention also provides a method for using the adjustable belt conveyor, comprising the following steps:

[0059] S1, conveying angle adjustment, control the output shaft of the second motor 29 to drive the first screw 28 to rotate, at this time the first screw 28 is threadedly connected with the limit rod 21, so that the limit rod 21 moves along the slide column 26 to the side of the first limit block 22, at this time the angle between the connecting rod 23 and the horizontal plane increases, so that the first limit block 22 and the connecting rod 23 rotate around the hinge point, the fixed block 24 and the second limit block 25 also rotate around the hinge point, so that the conveying angle of the belt 11 changes;

[0060] S2, conveying height adjustment, control the output shaft of the third motor 39 to drive the second lead screw 37 to rotate, at this time the second lead screw 37 is threadedly connected with the second fixing frame 35, so that the second fixing frame 35 moves upward or downward along the slide bar 34 on the inner wall of the slide slot 33, and at the same time the second fixing frame 35 drives the top horizontal plate 31 and the belt 11 to change in height;

[0061] S3, the belt conveyor moves, and the push rod end of the control electric cylinder 511 pushes the second gear rod 510 out, at which time the second gear rod 510 is meshed and connected with the second gear 58, so that the second gear 58 rotates, and at this time the second gear 58 drives the rotating shaft 52 and the two first gears 57 to rotate. When the first gear 57 rotates, it is meshed and connected with the first gear rod 55 and the third gear rod 512 respectively, so that the third gear rod 512 slides upward on the inner side of the track groove of the slide rail, so that the bottom plate 54 and the rubber bump 6 at the bottom thereof leave the ground, and at the same time, the first gear rod 55 slides downward on the inner side of the track groove of the slide rail, and the first gear rod 55 drives the vertical plate 56 to move downward, so that the multiple universal wheels 53 at the bottom of the vertical plate 56 contact the ground;

[0062] S4. The belt conveyor is placed stably, and the push rod end of the control electric cylinder 511 drives the second gear rod 510 to retract to the original position. At this time, the second gear rod 510 is meshed with the second gear 58, and the second gear 58 drives the rotating shaft 52 and the two first gears 57 to rotate. When the first gear 57 rotates, it is meshed with the first gear rod 55 and the third gear rod 512 respectively. The first gear rod 55 drives the vertical plate 56 and the universal wheel 53 to move upward and leave the ground, so that the third gear rod 512 slides downward on the inner side of the slide rail groove, and the third gear rod 512 pushes the bottom plate 54 and the multiple rubber bumps 6 at the bottom thereof to contact the ground.

[0063] In summary, by controlling the second motor 29 to drive the first screw 28 to rotate, the position of the limit rod 21 can be flexibly adjusted, so that the first limit block 22 and the connecting rod 23 rotate around the hinge point, and the fixed block 24 and the second limit block 25 also rotate around the hinge point, thereby changing the conveying angle of the belt 11, which can adapt to different height differences and conveying requirements, and improve the flexibility of the conveyor when in use.

[0064] The second lead screw 37 is driven to rotate by the output shaft of the third motor 39, and the second lead screw 37 enables the second fixed frame 35 to move upward or downward along the slide rod 34 on the inner wall of the slide groove 33, so that the height of the belt 11 changes, so that the conveyor can flexibly adapt to the transportation needs of goods at different heights. Whether it is low goods or high-stacked goods, the appropriate transportation height can be achieved through adjustment, thereby improving the versatility of the conveyor.

[0065] By controlling the push rod end of the electric cylinder 511, the second gear rod 510 can be quickly extended or retracted, thereby driving the mobile component 5 to work. In the stable conveying state, the bottom plate 54 and the rubber protrusion 6 at the bottom are in contact with the ground, increasing the contact area and friction between the conveyor base 51 and the ground, thereby improving the stability of the conveyor. The contact between multiple universal wheels 53 and the ground provides a stable and reliable moving foundation for the conveyor, allowing the conveyor to quickly switch between the moving and stable conveying states, greatly improving the working efficiency of the conveyor.
