Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] See also Figure 1-Figure 4 The figure shows a gravel spreading device for highway maintenance, comprising a box body 1, a spreading and leveling assembly and an anti-blocking assembly. A storage hopper 2 is provided on the top of the box body 1, one end of the storage hopper 2 is connected to the box body 1 through a cover body 3, moving wheels 4 are fixedly installed on both sides of the box body 1, and a discharge hopper 5 is connected at one end of the bottom of the box body 1; the spreading and leveling assembly is installed inside the box body 1, and the gravel falling from the storage hopper 2 is received and spread; the anti-blocking assembly is installed inside the cover body 3, and the gravel at the end of the cover body 3 is passed and the gravel in the middle of the cover body 3 is transported to both sides.

[0021] See also Figure 1-Figure 4 The spreading and leveling assembly shown in the figure includes a conveyor belt 6 arranged inside the box body 1, and both ends of the inner side of the conveyor belt 6 are meshed with conveyor wheels 7, one of which passes through the box body 1 and extends outward to be connected to the output end of the motor 8, and the outer side wall of the conveyor belt 6 is fixed with partition plates 9 at equal distances;

[0022] See also Figure 1-Figure 4 The spreading and leveling assembly shown in the figure also includes a scraper 10 arranged at the bottom of the box body 1, and a suspension rod 11 is fixedly provided above both ends of the scraper 10. Adjustment holes 12 are opened at equal distances on the suspension rod 11. The suspension rod 11 is inserted into the inside of the insert tube 13, and the insert tube 13 is fixedly installed on the outer wall of the box body 1. The insert tube 13 is threaded with a locking bolt 14 matching the adjustment hole 12.

[0023] See also Figure 2-Figure 4The anti-blocking assembly shown in the figure includes a rotating rod 15 arranged at the end of the cover body 3, and spiral blades 16 are fixedly provided at both ends of the rotating rod 15, and the two spiral blades 16 are arranged in opposite directions. One end of the rotating rod 15 and one end of the conveying wheel 7 both penetrate the box body 1 and extend outward to be fixedly connected with the gear 17, and the three gears 17 are meshed and connected by a toothed chain 18.

[0024] When gravel is spread for highway maintenance: first, the gravel to be spread is stored in the storage hopper 2, and then the motor 8 is started. The motor 8 can drive the rotating rod 15 at the output end to rotate, and the rotation of the rotating rod 15 can drive the gear 17 at the end to rotate. The gear 17 is engaged with the toothed chain 18 to drive the gear 17 at the end of the conveying wheel 7 to rotate, so that the conveying wheel 7 can be rotated, and the rotation of the conveying wheel 7 can drive the conveyor belt 6 to move.

[0025] When the rotating rod 15 rotates, it can flatten and transport the gravel on one side of the end of the cover body 3, and can transport the gravel accumulated and fallen in the middle of the cover body 3 to both sides of the end of the cover body 3, so that the gravel that falls from the end of the cover body 3 onto the conveyor belt 6 can be evenly scattered on the conveyor belt 6. Since the dividing plates 9 are fixed at equal distances on the conveyor belt 6, the fallen gravel can be separated at equal distances, so that the gravel that falls on the ground from the conveyor belt 6 can be evenly spread. When the conveyor belt 6 spreads the gravel, the workers push the box body 1 to move the box body 1 on the road section that needs maintenance. At this time, the gravel transported on the conveyor belt 6 will fall from the discharge hopper 5 at one end of the box body 1 and be spread on the ground, so that the spreading of the gravel can be achieved.

[0026] After the gravel falls and is spread on the ground, the movement of the box 1 can drive the scraper 10 below to move synchronously, so as to level the uneven positions of the gravel spread on the ground and achieve uniform spreading of the gravel on the ground. At the same time, during use, the staff can adjust the height of the scraper 10 according to the spreading thickness of the gravel. When adjusting, first turn the locking bolt 14 to separate it from the adjusting hole 12, and then pull the suspension rod 11 to the position in the insert tube 13 to achieve the height adjustment of the scraper 10. After the height adjustment of the scraper 10 is completed, the locking bolt 14 is screwed into the adjusting hole 12 on the suspension rod 11 to fix the scraper 10, increase the stability of the scraper 10 in placement and use, and at the same time facilitate the staff to adjust the scraper 10 according to the laying thickness of the gravel, thereby improving the convenience of operation and use by the staff.
