DETAILED DESCRIPTION

[0024] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

[0025] As Figures 1 to 8As shown, the present application provides an embodiment of an adjustable bulk material guiding and conveying device, which comprises two parallel support frames 1, the bottom of the support frame 1 is fixedly connected through the support leg 2, the inner side of the support frame 1 is provided with a material supporting mechanism 3 and a guide rail 4, the guide rail 4 is a closed track with circular arc bending at both ends, similar to a runway shape, the two straight line positions of the guide rail 4 are arranged in parallel in the vertical direction, and the material supporting mechanism 3 can slide along the guide rail 4.

[0026] The material supporting mechanism 3 comprises a plurality of support assemblies 5 slidingly arranged along the outer circle of the guide rail 4, the material supporting mechanism 3 is integrally coated with a conveying belt 6 along the outer circle, the top of each support assembly 5 abuts the inner side of the conveying belt 6, and the outer surface of the conveying belt 6 is used to place the material.

[0027] The support assembly 5 comprises a sliding seat 7, an elastic telescopic rod 8, a rod holder 9 and a supporting rod 10, the sliding seat 7 is slidingly connected with the guide rail 4, the elastic telescopic rod 8 is fixed on the upper surface of the sliding seat 7, the rod holder 9 is fixed on the top end of the elastic telescopic rod 8, the supporting rod 10 is fixed horizontally on the rod holder 9, the supporting rods 10 of the plurality of support assemblies 5 are arranged in parallel with each other to form a supporting surface, the width of the conveying belt 6 is the same as the length of the supporting rod 10, so that the supporting rod 10 can completely support the conveying belt 6, and the upper half of the conveying belt 6 is attached to the supporting surface.

[0028] The sliding seat 7 comprises a seat body 11, a spring piece 12 and a clamping rod 13, the spring piece 12 is arranged in a figure-eight shape, the upper end of the spring piece 12 is fixed in the inner top of the seat body 11, the seat body 11 is slidingly connected with the side of the guide rail 4, the lower end of the spring piece 12 is slidingly connected with the outer circle of the guide rail 4, and the clamping rod 13 is fixed on the lower end of the seat body 11 and slidingly clamped with the inner circle of the guide rail 4.

[0029] The material supporting mechanism 3 further comprises a power assembly 14, the power assembly 14 comprises an axle holder 15, a main shaft 16 and a belt pulley set 17, the axle holder 15 is fixed at both ends of the support frame 1, the main shaft 16 is rotatably installed on the axle holder 15 and passes through the center of the circular arc bending part of the guide rail 4, the end of the guide rail 4 is fixedly connected with the axle holder 15 through a connecting block 18, the belt pulley of the belt pulley set 17 is coaxially fixed on the main shaft 16, a plurality of push blocks 19 are further fixed on the belt of the belt pulley set 17, the push blocks 19 are arranged one by one with the sliding seat 7, when the belt pulley set 17 rotates, the push block 19 can abut against the clamping rod 13 and push the seat body 11 to slide along the guide rail 4.

[0030] When the material is conveyed, the material is first placed on the conveying belt 6, and the bottom of the material is in contact with the conveying belt 6. Under the action of gravity, the supporting rod 10 at the bottom of the conveying belt 6 is pressed downward, and the supporting rod 10 outside the material is not in contact with the material, so it maintains the original height. At this time, a depression is formed on the conveying belt 6, and it is difficult for the supporting rod 10 to be pressed from the side to make the supporting rod 10 descend, so the material can always be located in the depression. When the material is moved, the belt pulley set 17 of the power assembly 14 drives the push block 19 to move, and the push block 19 pushes each sliding seat 7 to slide along the guide rail 4. At this time, the supporting rod 10 at the bottom of the material and the supporting rod 10 outside the material move simultaneously to move the material. The supporting rod 10 can also drive the conveying belt 6 to move forward through friction when moving. The material is always located in the depression during conveying to prevent the material from rolling on the surface of the conveying belt 6. Multiple materials can form depressions at different positions of the conveying belt 6 during conveying, further preventing the materials from rolling and colliding.

[0031] One end of the support frame 1 is also provided with a connection mechanism 20. The connection mechanism 20 includes an arc-shaped track frame 21, a sliding frame 22, a locking rod 23, and a connection plate 24. The arc-shaped track frame 21 is fixed to one end of the support frame 1. The sliding frame 22 is slidingly connected to the arc-shaped track frame 21. The connection plate 24 is fixed to the sliding frame 22. One side of the connection plate 24 connects the output end of the conveying belt 6 and is used to support the material. One end of the locking rod 23 is fixed to the end of the sliding frame 22. The other end of the locking rod 23 is slidingly connected to the side of the shaft frame 15. The locking rod 23 is threadedly connected with a locking knob 25. Tightening the locking knob 25 can make the bottom of the locking knob 25 abut against the side of the shaft frame 15.

[0032] The bottom of the connection plate 24 is slidingly installed with a discharging plate 26. The discharging plate 26 is connected with the bottom of the connection plate 24 through a return spring 27. The surface of the discharging plate 26 is fixed with a plurality of rotating friction blocks 28. The surface of the connection plate 24 is provided with a through hole. The rotating friction blocks 28 pass through the connection plate 24 from the through hole.

[0033] The cross section of the rotating friction block 28 is in the shape of a horizontally arranged water drop. The surface of the discharging plate 26 is fixed with a friction seat 29. The rear end of the rotating friction block 28 is rotatably installed in the friction seat 29. The diameter of the rear end of the rotating friction block 28 is greater than the thickness of the connection plate 24.

[0034] The working principle of the connecting mechanism 20 is that when the material falls from the conveying belt 6, the material is guided by the connecting plate 24, after loosening the locking knob 25, the carriage 22 is moved up and down along the arc-shaped track frame 21 to adjust the height of the connecting plate 24, and after the adjustment is completed, the locking knob 25 is tightened, so that the material on the conveying belt 6 can be moved to the subsequent platform of different heights, realizing the buffering of the material, preventing the material from directly falling from the higher conveying belt 6 to other platforms, when the sliding seat 7 moves to the position of the connecting plate 24, the clamping rod 13 on the sliding seat 7 can push the discharging plate 26 to move forward, the discharging plate 26 moves to drive the rotating friction block 28 to move forward, the rotating friction block 28 moves forward, the rear end of the rotating friction block 28 is higher than the surface of the connecting plate 24, so it can contact the bottom of the material on the connecting plate 24, when the rotating friction block 28 moves forward, the rotating friction block 28 will rotate and make the front end lift, the front end of the rotating friction block 28 lifts to abut against the bottom of the material to increase the friction with the material, pushing the material to move along the surface of the connecting plate 24, when the clamping rod 13 disengages from the discharging plate 26, the reset spring 27 drives the discharging plate 26 to move backward, the front end of the rotating friction block 28 disengages from the material after the reverse movement, reducing the friction between the material, preventing the material from moving backward, and repeating the above steps can move the material along the surface of the discharging plate 26 in one direction, so that the discharging plate 26 can still transport the material it receives to platforms of different heights when it is adjusted to a horizontal state or an upward state.
