[0041] Please refer to Figure 1 、 Figure 2 and Figure 5 The feeding slide 6 is provided with a discharging mechanism 7 on both sides, the discharging mechanism 7 comprises a motor 71, a universal coupling 72, a bearing seat 73, a lower screw rod 74 and an upper screw rod 75, and the vertical cylinder of the feeding slide 6 is provided with the motor 71 installed on the guide rail 1, and the top output rod of the motor 71 is connected with the universal coupling 72.

[0043] In specific implementation, the motor 71 is started to drive the universal coupling 72 to rotate, so that the lower screw rod 74 and the upper screw rod 75 in the two groups of bearing seats 73 rotate at the same time, so that the lowermost safety cone placed in an inverted manner abuts on the two groups of upper screw rods 75, when the upper screw rod 75 rotates, the bottom plate of the safety cone can be clamped in the gap between the helical blades, when the safety cone continuously moves downward, because the pitch length of the lower screw rod 74 is greater than the pitch length of the upper screw rod 75, and the thickness of the helical blade of the lower screw rod 74 is greater than the thickness of the helical blade of the upper screw rod 75, when the lower screw rod 74 rotates and connects with the bottom plate of the safety cone, the distance of the safety cone moving downward can be greater, so that the safety cone delivered by the lower screw rod 74 is pulled away from the safety cone delivered by the upper screw rod 75, and it is ensured that the lowermost safety cone will not be tightly inserted with the safety cone of the upper layer when it is placed downward, so that the lowermost safety cone is placed more efficiently when it falls.

[0044] At the same time, the safety cone placed downward will be extruded with the buffer strip 61 on the inner wall of the vertical cylinder of the feeding slide 6, so that the buffer strip 61 buffers the safety cone placed downward, and it is ensured that the safety cone can be smoothly guided out of the bottom opening of the feeding slide 6 due to the action of gravity.

[0045] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8 , one side of the top of the guide rail 1 is welded and fixed with the limiting seat 3, the upper and lower bent sections of the reinforcing plate 2 and the tail of the horizontal straight section of the upper end are all installed with guide wheels 4, the inside of the guide rail 1 is sleeved with a feeding belt 5 for conveying safety cones, the guide wheels 4 penetrate through the reserved openings in the inner side surface of the guide rail 1, and the feeding belt 5 is wound around the outer side of the plurality of guide wheels 4, and a cushion plate 51 is arranged between adjacent two feeding belts 5;

[0046] The limiting seat 3 is in the shape of "E", and the inside of the "E" shaped limiting seat 3 is provided with two downward openings, and the two downward openings are a long opening and a short opening respectively, a support 8 is rotatably connected in the long opening of the limiting seat 3, a mounting plate 81 is fixed to the bottom of the support 8, the middle part of the mounting plate 81 is butted with a first gear 82 through a connecting shaft, a second gear 83 engaged with the first gear 82 is connected to one side of the mounting plate 81, and a friction wheel 84 is fixed to the middle hollow shaft 844 of the second gear 83;

[0047] A hydraulic rod 88 is connected to one side of the limiting seat 3 close to the support 8, the output end of the hydraulic rod 88 is rotatably connected with the side surface of the support 8, the friction wheel 84 abuts against the outer wall surface of the rear wheel 11 of the transport vehicle 10, a lower pulley 85 is fixed to the tail end of the connecting shaft of the first gear 82, a transmission belt 86 is sleeved on the outer side of the lower pulley 85, one end of the transmission belt 86 away from the lower pulley 85 is sleeved with an upper pulley 87, the rotating shaft of the upper pulley 87 is butted in the short opening of the limiting seat 3, the rotating shaft of the upper pulley 87 is fixed with one of the guide wheels 4 at the tail of the horizontal straight section of the reinforcing plate 2, and the rotating shaft of the upper end of the support 8 is on the same axis line with the rotating shaft of the upper pulley 87;

[0048] The guide rail 1 is in the shape of "C" composed of a top horizontal straight section, a top bent section, a middle longitudinal straight section and a bottom bent section, and the top horizontal straight section of the guide rail 1 is welded and communicated with the bottom of the feeding slide 6; the cushion plates 51 on the outer side of the feeding belt 5 are distributed at equal intervals, and the cushion plates 51 are made of rubber material.

[0049] In specific implementation, the safety cone dropped from the bottom of the vertical cylinder of the feeding slide 6 falls on the two feeding belts 5 inside the guide rail 1, so that the two feeding belts 5 can hold the safety cone, when the safety cone falls and the tip of the safety cone abuts against the cushion plate 51 of the feeding belt 5, the safety cone is blocked from moving downward, when the feeding belt 5 continues to rotate and the cushion plate 51 moves away from the bottom opening position of the vertical cylinder of the feeding slide 6, the safety cone will automatically fall;

[0050] When the hydraulic rod 88 is started to extend, the hydraulic rod 88 pushes the support 8 to rotate, so that the support 8 drives the friction wheel 84 on one side of the mounting plate 81 to be in contact with the rear wheel 11 of the trolley 10, so that the trolley 10 driving the rear wheel 11 rotates forward, and the friction wheel 84 in contact is reversed, so that the rear wheel 11 drives the second gear 83 and the first gear 82 to mesh and drive, so that the first gear 82 drives the lower pulley 85 to rotate forward, at this time, the lower pulley 85 drives the upper pulley 87 to rotate forward through the transmission belt 86, so that the upper pulley 87 drives one of the guide wheels 4 at the tail of the horizontal straight section of the reinforcing plate 2 to rotate through the rotating shaft, so that the feeding belt 5 and the pad 51 cooperate to realize automatic conveying of the safety cone along the guide rail 1; When the trolley 10 travels fast, the speed of the rear wheel 11 will be accelerated, so that the speed of the transmission belt 86 is accelerated, and the speed of the feeding belt 5 conveying the safety cone along the guide rail 1 is accelerated, when the speed of the trolley 10 is accelerated, the speed of the safety cone is accelerated by adjusting the speed of the discharging mechanism 7 to accelerate the speed of the safety cone, and the equal interval placement can be ensured, when the speed of the trolley 10 slows down, the speed of the friction wheel 84 and the rear wheel 11 in contact is slowed down, so that the feeding belt 5 slows down, so that the feeding belt 5 can drive the safety cone to be placed at a slower speed from the lower opening of the guide rail 1, and the speed of the safety cone is slowed down by adjusting the speed of the discharging mechanism 7 to slow down the speed of the safety cone, and the equal interval placement of the safety cone can be ensured;

[0051] When conveying, the operation of the feeding belt 5 will complete the conveying of the safety cone along the track of the top horizontal straight section, the top curved section, the middle longitudinal straight section and the bottom curved section of the guide rail 1, in the conveying process, the safety cone can be limited and prevented from shaking through the auxiliary limitation of the adjacent two pads 51, when the safety cone is conveyed to the bottom curved section position of the guide rail 1, the safety cone is guided out through the opening at the bottom of the guide rail 1, and the safety cone is placed stably on the road;

[0052] When the hydraulic rod 88 pulls the support 8 to rotate reversely, so that the friction wheel 84 is away from the rear wheel 11, the feeding belt 5 will not convey the safety cone.

[0053] Please refer to Figures 9-11The friction wheel 84 is composed of a wheel disc 841, arc-shaped rotating blocks 842 and wear-resistant sleeves 843, a hollow shaft 844, a pneumatic cylinder 845, ball discs 846, a rotating sleeve 847 and adjusting arms 848. The wheel disc 841 is fixed to the outer wall of the hollow shaft 844, which is connected to the side wall of the mounting plate 81 through a bearing. The outer edge of the wheel disc 841 is movably connected with the arc-shaped rotating blocks 842 through a rotating shaft. The arc-shaped rotating blocks 842 are distributed at equal angles and have a 60° arc-shaped structure. The outer wall of the arc-shaped rotating blocks 842 is bonded with the wear-resistant sleeves 843 made of rubber. The pneumatic cylinder 845 is installed on the side of the mounting plate 81 away from the second gear 83. Two ball discs 846 are welded to the output rod of the pneumatic cylinder 845 extending out of one end of the hollow shaft 844. The rotating sleeve 847 is arranged between the two ball discs 846 and is rollingly connected with the output rod of the pneumatic cylinder 845 through steel balls. The outer wall of the rotating sleeve 847 is movably connected with the adjusting arms 848, and the end of the adjusting arms 848 away from the rotating sleeve 847 is rotatably connected with the inner wall of the arc-shaped rotating blocks 842.

[0054] In specific implementation, the rotating sleeve 847 is moved along the hollow shaft 844 by controlling the pneumatic cylinder 845, so that the arc-shaped rotating blocks 842 are supported by the adjusting arms 848 when the rotating sleeve 847 moves horizontally, so that the arc-shaped rotating blocks 842 are opened outward around the rotating shaft, so as to increase the opening of the arc-shaped rotating blocks 842. When the opening of the arc-shaped rotating blocks 842 is increased, the wear-resistant sleeves 843 on the outer wall are opened to become a conical surface structure, so that the friction wheel 84 changes from a cylindrical structure to a conical structure. When the friction wheel 84 is in contact with the rear wheel 11, the rotation of the friction wheel 84 drives the wheel disc 841 to rotate around the hollow shaft 844, and the arc-shaped rotating blocks 842 drive the rotating sleeve 847 to rotate around the output shaft of the pneumatic cylinder 845 through the adjusting arms 848. The rotating sleeve 847 is positionally limited by the two groups of ball discs 846 distributed in parallel when rotating;

[0055] Therefore, when the arc-shaped rotating blocks 842 are adjusted to rotate and open by the pneumatic cylinder 845, the wear-resistant sleeves 843 can be opened to a certain opening degree. When the arc-shaped rotating blocks 842 are adjusted to rotate and contract by the pneumatic cylinder 845, the wear-resistant sleeves 843 can be contracted to a certain opening degree. Therefore, when the speed of the rear wheel 11 is unchanged, the rotation speed of the friction wheel 84 can be reduced, and when the speed of the rear wheel 11 is unchanged, the rotation speed of the friction wheel 84 can be increased. Therefore, the length of the pneumatic cylinder 845 can be adjusted to steplessly adjust the rotation speed of the transmission belt 86, so that the placement interval of the safety cone can be changed by adjusting the feeding belt 5.

[0056] Please refer to Figure 2 , Figure 3 and Figure 7The middle longitudinal straight section of the guide rail 1 is thickened, and a groove 9 is arranged in the middle longitudinal straight section of the guide rail 1. The groove 9 is internally connected with a spring 91, and the inner side upper end of the groove 9 is rotationally connected with a scraping plate 92. The groove 9 is longitudinally and equally spaced, and the scraping plate 92 is in a fan-shaped structure.

[0057] In specific implementation, when the safety cone is transported along the top curved section of the guide rail 1 to the middle longitudinal straight section, the safety cone can be horizontally placed in the middle longitudinal straight section. At this time, the bottom plate of the safety cone can press the scraping plate 92 downward, so that the scraping plate 92 can press the spring 91 in the groove 9. Since the groove 9 and the scraping plate 92 are equally spaced, when the scraping plate 92 moves vertically downward, the scraping plate 92 can be rotated to scrape the dirt such as stones and soil attached to the surface of the bottom plate of the safety cone, so as to ensure that the safety cone is more stable when placed on the road.

[0058] Please refer to Figure 8 The limiting seat 3 is away from the surface of the middle longitudinal straight section of the guide rail 1 and is provided with a sliding groove 31. The sliding groove 31 is internally connected with an adjusting screw 32 through a bearing. The adjusting screw 32 is threadedly connected with one side of a hook plate 33. The vertical side surface of the hook plate 33 is connected with a knob 34 for abutting against the guard plate of the transport vehicle 10. The hook plate 33 and the sliding groove 31 form a sliding structure through the adjusting screw 32.

[0059] Please refer to Figure 1 and Figure 2 The middle longitudinal straight section of the guide rail 1 is externally welded with two groups of mounting pins 12, which are in an “L” shape. The outer wall of the transport vehicle 10 is welded with a hanging sleeve 13, and the mounting pin 12 is inserted into the hanging sleeve 13.

[0060] In specific implementation, the mounting pin 12 of the middle longitudinal straight section of the guide rail 1 is inserted into the hanging sleeve 13 of the side guard plate of the transport vehicle 10. The limiting seat 3 of the side of the guide rail 1 is abutted against the side guard plate of the transport vehicle 10. The limiting seat 3 is hung on the side guard plate of the transport vehicle 10 through the hook plate 33. The adjusting screw 32 is rotated according to the height of the hooking. The hook plate 33 slides up and down along the sliding groove 31. When the hook plate 33 is abutted against the side guard plate of the transport vehicle 10, the mounting pin 12 and the hanging sleeve 13 can be matched and connected. The knob 34 on the side of the hook plate 33 is rotated, so that the knob 34 can abut against and press the side guard plate of the transport vehicle 10. The safety cone automatic placing device can be stably installed on the transport vehicle 10 for loading safety cones.
