[0020] The bottom of the frame 1 is provided with a universal caster 2 with a brake. The conveyor belt 3 is driven by the driving roller 4 driven by the driving mechanism to rotate. Starting from the driving roller 4, along the running direction of the conveyor belt 3, it is sequentially wound around a pair of telescopic rollers 5 of the telescopic mechanism, a lower belt roller 6, a pair of tensioning rollers 7 of the tensioning mechanism, a transition belt roller 8, and an upper belt roller 9. After winding around for one circle, the conveyor belt 3 is driven to be telescopic by the telescopic mechanism and is kept tensioned by the tensioning mechanism. The driving roller 4, the telescopic roller 5, the lower belt roller 6, the tensioning roller 7, the transition belt roller 8, The central axes of the upper belt rollers 9 remain parallel and can rotate around their respective central axes. The active roller 4 and the lower belt roller 6 are one above the other and aligned vertically. The transition belt roller 8 and the upper belt roller 9 are one above the other and aligned vertically. A pair of telescopic rollers 5 are located between the active roller 4 and the tensioning roller 7 in the height direction, and are cantilevered in front of the active roller 4 and the lower belt roller 6. Along the telescopic direction of the telescopic mechanism, a pair of tensioning rollers 7 are located between the lower belt roller 6 and the transition belt roller 8, and the transition belt roller 8 and the upper belt roller 9 are located behind the tensioning roller 7.

[0021] In a specific implementation, the corresponding structural arrangement of the movable hydraulic telescopic conveyor also includes:

[0022] The driving mechanism includes a driving motor 10 and a belt transmission mechanism. The motor output shaft of the driving motor 10 is coaxially connected to the driving pulley 11 of the belt transmission mechanism, and the driven pulley 12 of the belt transmission mechanism is coaxially connected to the driving roller 4, driving the driving roller 4 to rotate, and the outer roller circumference of the driving roller 4 maintains contact with the conveyor belt 3.

[0023] The telescopic mechanism includes a hydraulic telescopic arm 13 and a pair of telescopic rollers 5. The pair of telescopic rollers 5 are driven by the hydraulic telescopic arm 13 to move horizontally forward or backward. The conveyor belt 3 extends forward or retracts backward with the displacement of the pair of telescopic rollers 5 and maintains contact with the pair of telescopic rollers 5.

[0024] The telescopic mechanism is provided with a control box 18 , through which the start and stop of the hydraulic telescopic arm 13 are controlled.

[0025] A pair of tensioning rollers 7 of the tensioning mechanism are arranged one in front of the other and one behind, one up and one down. The tensioning roller 7 at the bottom is adjacent to the transition belt roller 8, and the tensioning roller 7 at the top is adjacent to the lower belt roller 6. The two axial ends of each tensioning roller 7 are rotatably supported around the central axis by ball bearings 14 on a pair of slide grooves 15 on the left and right sides of the frame 1, and can slide along the slide groove 15 in the front and back directions together with the ball bearings 14. A spring 16 is horizontally arranged in the front and back directions in the slide groove 15, and the spring 16 is tensioned between the ball bearing 14 and a support seat 17 fixedly set in the slide groove 15.

[0026] The extension and contraction of the conveyor belt 3 can be carried out in the following manner:

[0027] Taking extension as an example, the hydraulic telescopic arm 13 extends forward, driving a pair of telescopic rollers 5 to move forward, and the conveyor belt 3 is pushed forward by the pair of telescopic rollers 5, and then extended. During the process, due to the existence of the tensioning mechanism, the spring 16 is deformed, and the pair of tensioning rollers 7 slide along the slide groove 15 along the forward and backward directions through the ball bearing 14. The elastic force of the spring 16 is used to keep the conveyor belt 3 always tensioned, so that the conveyor belt 3 is extended and can run stably. The contraction of the conveyor belt 3 can be deduced by analogy.
