when the widths of the first conveying belt 1-2 and the second conveying belt 1-3 are changed according to actual requirements, in order to adapt to the widths of the first conveying belt 1-2 and the second conveying belt 1-3 with different widths, the bottom end belt pulleys 1-16 are manually rotated, the bottom end straight teeth 1-15 are driven to rotate by the bottom end belt pulleys 1-16, the expansion rollers 1-10 are driven to rotate by the meshing transmission of the bottom end straight teeth 1-15 and the expansion rollers 1-10, the expansion rollers 1-10 are driven to rotate, and the expansion roller plates 1-18 and the expansion roller plates 1-1 are driven to be respectively far away from the middle end sleeve pipes 1-19 and the middle end sleeve pipes 1-13 by the connection of threaded chutes on the expansion rollers 1-10, the expansion rods 1-11 and the expansion rods 1-17, so that the expansion roller plates 1-18 and the middle end sleeve pipes 1-19 or the expansion roller plates 1-1 and the middle end sleeve pipes 1-13 are further The distance between the two belts is changed, so that the belts can conveniently adapt to the first conveying belt 1-2 and the second conveying belt 1-3 with different widths, and the capabilities of conveying stones are different when the first conveying belt 1-2 and the second conveying belt 1-3 with different widths are used; when the transmission ratio of the input assembly 4 needs to be changed according to actual conditions, the rocker levers 4-14 are manually rotated, the using positions of the support rods 4-15 on the rectangular bosses I4-13 are changed through threaded connection between the rocker levers 4-14 and the support rods I4-15, the meshing positions of the bevel gear rollers 4-5 and the meshing bevel gears I4-21 are changed through driving of the support rods I4-15, the meshing positions of the bevel gear rollers 4-5 and the meshing bevel gears I4-21 are changed, the distance ratio of the meshing positions to the rotating axes of the bevel gear rollers 4-5 and the meshing bevel gears I4-21 is changed, and the transmission ratio is changed; when the use position of the first meshing bevel gear 4-21 is changed, the form of the first middle-end transmission belt 4-22 in matched connection with the first meshing bevel gear 4-21 is changed, in order to keep the transmission between the first middle-end transmission belt 4-22 and the first meshing bevel gear 4-21 not to fail, the first tensioning slider 4-16 is pushed by the elastic force of the first tensioning spring 4-18, so that the first tensioning slider 4-16 slides on the first support sliding rod 4-17, and the first middle-end transmission belt 4-22 is tensioned by the first tensioning slider 4-16, so that the transmission failure of the first middle-end transmission belt 4-22 is prevented; stone to be transported is thrown in from the upper end of the feeding device 2, meanwhile, the gate driving rod 2-3 is manually pushed, the gate 2-2 is driven to slide in the side wall sliding groove I2-8 through the gate driving rod 2-3, so that a gap is formed between the gate 2-2 and the inner wall of the feeding outer frame 2-1, and the stone can fall conveniently; the gate 2-2 is conveniently driven to change the size of the gap between the gate 2-2 and the inner wall of the feeding outer frame 2-1 through the use position of the gate driving rod 2-3 on the side wall rod I2-9, so that the falling rock amount is conveniently changed; when the weight of the stone falling into the conveying device 1 is suddenly increased, the first wedge-shaped push rod 3-2 is driven to move downwards by the first clip-shaped rod 1-5 in the conveying device 1, and the second wedge-shaped push rod 3-2 shields the gate 2-2 to change the gap between the gate 2-2 and the inner wall of the feeding outer frame 2-1 through the action of the first wedge-shaped push rod 3-2 on the second driven push rod 3-3, so that the stone falling amount is reduced; when the falling rock amount is in a gap, under the pushing of the elastic force of the first pushing spring 3-4 of the driven push rod, the second driven push rod 3-3 reversely pushes the first wedge-shaped push rod 3-2, so that the first wedge-shaped push rod 3-2 moves upwards, and meanwhile, the second driven push rod 3-3 shields the gate 2-2 to change the area of the gap between the gate 2-2 and the inner wall of the feeding outer frame 2-1 to be reduced, so that the falling rock amount is recovered; thereby achieving the protective effect on the transportation device 1.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and variations can be made by those skilled in the art within the spirit and scope of the present invention; modifying; and the addition or the replacement also belongs to the protection scope of the invention.
