Description

Technical Field

[0001] The utility model relates to the field of plastic runway construction equipment, in particular to a plastic runway particle anti-blocking paving device. Background Art

[0002] In order to improve the anti-slip effect of the plastic track, it is necessary to lay a layer of anti-slip particles on the top surface of the plastic track. The anti-slip particles can be made of rubber particles, which have a certain elasticity and do not affect the overall elastic shock absorption effect of the plastic track.

[0003] In order to ensure the uniformity of the anti-skid particles on the top surface of the plastic track, it is necessary to control the discharge rate of the particles. Existing equipment for laying particles on plastic tracks mostly uses screw conveyors to transport the particles, which is costly. For example, the utility model patent with announcement number CN117822382A discloses a PU plastic track particle laying equipment that uses an auger to transport the material. The outlet of the screw conveyor is small, which is not conducive to laying the particles on a wider plastic track. If the particles are simply discharged through a discharge port, clogging problems may occur, which requires improvement. Utility Model Content

[0013] The beneficial effects of the utility model: a device for paving particles to prevent blockage of a plastic runway. During the forward movement of the cart, the anti-skid particles in the material box flow out through the discharge port and are sent to the top surface of the plastic runway along the guide plate, and are rolled by a pressure roller to ensure that the thickness of the anti-skid particles distributed on the plastic runway is uniform. During the process of the anti-skid particles flowing out through the discharge port, the pressure plate is used to perform slight lateral reciprocating movements, which can not only avoid the blockage of the anti-skid particles, but also improve the uniformity of the distribution of the anti-skid particles on the guide plate, thereby further improving the effect of particle paving.

[0016] The following combination Figures 1 to 2 The technical solution of the present utility model is further illustrated by specific embodiments.

[0017] like Figure 1 The plastic track particle anti-blocking paving device shown includes: a cart 1, a gate 17, a material box 2, a material guide plate 3, a pressure plate 6 and a pressure roller 8. The material box 2 is set on the cart 1, and a roller 4 is set at the bottom of the cart 1 to facilitate the forward movement of the cart 1 on the plastic track.

[0018] The guide plate 3 is positioned at the bottom of the material box 2 and extends diagonally downward to the rear of the cart 1. The material box 2 is provided with a discharge port 5 located above the guide plate 3. As the cart 1 moves forward, the anti-skid particles in the material box 2 flow out through the discharge port 5 and are delivered along the guide plate 3 to the top surface of the plastic track. The discharge port 5 is wide enough to accommodate relatively wide plastic tracks. Baffles 15 are provided on both sides of the guide plate 3 at the rear of the material box 2 to prevent the anti-skid particles from escaping from the sides of the guide plate 3.

[0019] The gate plate 17 is arranged in a liftable manner in the material box 2 to control the opening and closing of the discharge port 5. A cross beam 18 is provided on the top of the material box 2. A first screw 19 is provided on the top of the gate plate 17 and passes through the cross beam 18 upward. A first nut 20 is provided on the first screw 19 and is located above the cross beam 18. It is convenient to adjust the height of the gate plate 17 by manually tightening the first nut 20 to realize the opening and closing of the discharge port 5, and the operation is simple.

[0020] A cantilever 13 extending backward and located above the material guide plate 3 is provided at the rear part of the material box 2. The pressure roller 8 is arranged below the cantilever 13 and behind the material guide plate 3 so as to be adjustable in height. In this embodiment, a second screw 12 is provided on the top of the pressure roller 8 and passes through the cantilever 13 upward. The second screw 12 is provided with a second nut 14 located above and below the cantilever 13 to adjust the height of the pressure roller 8 so that the distance between the bottom of the pressure roller 8 and the top surface of the plastic track corresponds to the particle size of the anti-slip particles, so that the anti-slip particles are spread flat to ensure uniform thickness.

[0021] The pressing plate 6 is arranged in the discharge port and extends backward in parallel with the guide plate 3. The distance between the pressing plate 6 and the guide plate 3 corresponds to the particle size of the anti-slip particles, so that the anti-slip particles flow downward from the gap between the pressing plate 6 and the guide plate 3.

[0022] A suspension rod 16 is provided at the bottom of the cantilever, and a guide column 7 is provided on the suspension rod 16 and extends horizontally along the width direction of the discharge port 5. Figure 2 As shown, the pressing plate 6 is provided with a linear bearing 23 mounted on the guide post 7 to guide the lateral movement of the pressing plate 6. The suspension rod 16 is provided with a reciprocating drive mechanism that drives the pressing plate 6 to move along the width direction of the discharge port 5. As the anti-skid particles flow out of the discharge port 5, the pressing plate 6 is slightly reciprocated in the lateral direction. This can not only avoid blockage of the anti-skid particles, but also improve the uniformity of the distribution of the anti-skid particles on the guide plate 3, which can further improve the particle laying effect.

[0023] like Figure 1 and Figure 2 As shown, in this embodiment, the reciprocating drive mechanism includes a motor 11, a crank arm 22 and a connecting rod 10. A pin seat 9 is provided on the pressure plate 6. The motor 11 is provided on the suspension rod 16 and is located on the side above the pin seat 9. The crank arm 22 is provided on the rotating shaft of the motor 11. The connecting rod 10 is provided between the crank arm 22 and the pin seat 9. The motor 11 is used to drive the rotation of the crank arm 22, and the pressure plate 6 is driven to reciprocate through the connecting rod 10.

[0024] In this embodiment, the cart 1 is provided with a mobile power supply 21 for powering the motor 11. The mobile power supply 21 is flexible and can be recharged repeatedly to power the motor 11, so as to meet the needs of the cart 1 for mobile laying of anti-slip particles on the plastic track.
