Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Please refer to Figures 1 to 5 .

[0037] A foldable telescopic belt conveyor provided in an embodiment of the present invention includes: a tail bracket 10, a rotating arm bracket 20, a telescopic frame assembly 30, a tail roller 40, a head roller 50, a belt 60, a rotating drive device 70 and a telescopic drive device 80. The tail bracket 10 can be installed on the frame of the crushing and screening equipment through the tail adjustment frame 13. The tail end of the rotating arm bracket 20 is hinged to the front end of the tail bracket 10. Specifically, the rotating arm bracket 20 is connected to the tail bracket 10 through a rotating shaft 11. The telescopic frame assembly 30 is movably connected to the rotating arm bracket 20. The tail roller 40 is arranged on the tail bracket 10, and the head roller 50 is arranged at the front end of the telescopic frame assembly 30. The belt 60 is wound around the tail roller 40 and the head roller 50. The rotating drive device 70 is respectively connected to the tail bracket 10 and the rotating arm bracket 20, and the telescopic drive device 80 is respectively connected to the tail bracket 10 and the telescopic frame assembly 30. When in working state, the rotary drive device 70 can drive the rotary arm 20 to rotate to unfold the rotary arm 20, and at the same time the telescopic drive device 80 drives the telescopic frame assembly 30 to extend to increase the length of the belt 60 machine, thereby ensuring the transportation capacity of the belt 60 machine; during transportation, the rotary drive device 70 drives the rotary arm 20 to rotate in the opposite direction to retract the rotary arm 20, and at the same time the telescopic drive device 80 drives the telescopic frame assembly 30 to retract to reduce the length of the belt 60 machine, thereby reducing the space occupied by the belt 60 machine, thereby facilitating transportation.

[0038] In some embodiments, as Figure 1 and Figure 2 As shown, the telescopic frame assembly 30 includes a first-stage telescopic frame 31, a second-stage telescopic frame 32, a head frame 33, and a head adjustment frame 34. The head roller 50 is preferably a motorized roller. The head roller 50 is connected to the head adjustment frame 34, which is in turn connected to the head frame 33. For example, the head adjustment frame 34 includes two supports, one of which is connected to either side of the head frame 33. The ends of the head roller 50 are connected to the two supports. The supports are connected to the head frame 33 via adjustment screws. By adjusting the screw length, the position of the supports can be adjusted, thereby adjusting the deflection of the head roller 50. The head frame 33 is slidably connected to the second-stage telescopic frame 32, which is slidably connected to the first-stage telescopic frame 31, which is slidably connected to the rotating arm 20. The front ends of the first-stage telescopic frame 31, the second-stage telescopic frame 32, and the rotating arm 20 are equipped with stoppers to prevent them from falling off the frame. Additional telescopic frames can be added to further increase the length of the belt 60. The first-stage telescopic frame 31 , the second-stage telescopic frame 32 and the rotating arm frame 20 each include two longitudinal frames arranged parallel to each other and a crossbeam arranged between the longitudinal frames.

[0039] In some embodiments, as Figure 3As shown, the telescopic drive device 80 includes a telescopic cylinder 81 and a telescopic link mechanism 82. One end of the telescopic cylinder 81 is connected to the rotating arm 20. Specifically, one end of the telescopic cylinder 81 can be connected to the crossbeam of the rotating arm 20, and the other end of the telescopic cylinder 81 is connected to one end of the telescopic link mechanism 82. The other end of the telescopic link mechanism 82 is connected to the head support 33. When the rotating arm 20 is deployed, the telescopic cylinder 81 can be extended, thereby causing the telescopic link mechanism 82 to drive the head support 33, the first-stage telescopic frame 31, and the second-stage telescopic frame 32 to extend; Figure 4 As shown, when transportation is required, the head support 33, the first-stage telescopic frame 31 and the second-stage telescopic frame 32 can be retracted first, and then the rotating arm 20 is rotated upward by 90° to retract the belt 60.

[0040] In some embodiments, as Figure 5 As shown, the telescopic linkage mechanism 82 is a scissor-type linkage mechanism, comprising multiple groups of sequentially hinged rods. Each group includes two connecting rods hinged at the center by a connecting axis 823. A fixing seat 825 is provided at the end of one of the connecting rods 821 in the end group. The fixing seat 825 is hinged to the rotating arm 20. This connecting rod 821 is also provided with a connecting shaft 824 hinged to the telescopic cylinder 81. Guide wheel grooves are provided within the first-stage telescopic frame 31, the second-stage telescopic frame 32, and the head support 33. A pulley 822 is provided on the hinged shaft on one side of the scissor-type linkage mechanism. The pulley 822 is located in the guide wheel groove. When the scissor-type linkage mechanism is extended or retracted, the pulley 822 can move within the guide wheel groove, thereby ensuring the stability of the scissor-type linkage mechanism during extension and retraction.

[0041] In some embodiments, as Figure 1 and Figure 2 As shown, the foldable and retractable belt 60 machine also includes a rope 90, which includes a steel wire rope and a lock buckle. A connecting frame is provided on the head bracket 33, and the connecting frame is preferably an n-shaped frame, and the connecting frame is tilted toward the frame, wherein there is an angle between the n-shaped frame and the head bracket 33, one end of the rope 90 is connected to the connecting frame, and the other end is used to connect to the frame of the crushing and screening equipment. The rope 90 can improve the stability of the belt 60 machine when it is extended.

[0042] In some embodiments, upper roller assemblies 35 are provided on the tops of the first-stage telescopic frame 31, the second-stage telescopic frame 32, and the head frame 33, and lower roller assemblies 36 are provided on the bottoms. Furthermore, upper roller assemblies 35 are provided on the tops of the rotating arm frame 20 and the tail frame 10, and lower roller assemblies 36 are provided on the bottoms. The upper roller assemblies 35 and lower roller assemblies 36 can improve the support stability of the belt 60.

[0043] In some embodiments, the upper roller assembly 35 is provided with a side guard 351 that spans both sides of the belt 60. The side guard 351 can optionally have an N-shaped structure, which can prevent the belt 60 from detaching from the upper roller assembly 35. In addition, upper limit rods 321 are provided on both sides of the upper portion of the belt 60 at the head roller 50 end. The upper limit rods 321 can be installed on the second-stage telescopic frame 32. Lower limit rods 15 are also provided on both sides of the lower portion of the belt 60 at the tail roller 40 end. The lower limit rods 15 can be installed below the tail bracket 10 to prevent the belt 60 from deviating. To facilitate material dropping, the tail bracket 10 is provided with a hopper 14. The hopper 14 is located above the belt 60, and the bottom of the hopper 14 is connected to the tail bracket 10 via support rods.

[0044] In some embodiments, the rotation drive device 70 includes a hydraulic cylinder assembly. A first articulated seat 12 is provided on the side of the tail support 10, and a second articulated seat is provided on the side of the rotating arm 20. The ends of the hydraulic cylinder assembly are respectively hinged to the first articulated seat 12 and the second articulated seat. The two hydraulic cylinder assemblies are each provided on either side of the tail support 10 and the rotating arm 20 to improve the rotational stability of the rotating arm 20.
