DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] As Figures 1 - 3As shown in the figure, an equidistant marking device for road construction includes a vehicle body 12, a pair of vertical plates 3, a main shaft 16, and a hopper 9 filled with lime. The pair of vertical plates 3 are arranged on both sides of the bottom of the vehicle body 12. The main shaft 16 rotates through the pair of vertical plates 3. Wheels 1 are arranged at both ends of the main shaft 16, and an incomplete gear 2 is arranged at the center. The diameter of the incomplete gear 2 is smaller than that of the wheels 1. A chute 4 is horizontally opened at the center position of the bottom of the vehicle body 12. A slide bar 13 is slidably arranged in the chute 4. A rack 15 is arranged at the bottom of the slide bar 13. The incomplete gear 2 can mesh with the rack 15. The top of the hopper 9 is provided with a feed inlet 8 and is arranged on the upper part of the vehicle body 12. The bottom of the hopper 9 penetrates through the vehicle body 12 to form a discharge port 7. A baffle 6 is slidably arranged at the position corresponding to the discharge port 7 at the bottom of the vehicle body 12 through a sliding member. A through hole 5 is opened on the baffle 6. The sliding member can make the baffle 6 tend to block the discharge port 7. A tension spring 14 is arranged between the end of the slide bar 13 corresponding to the side away from the baffle 6 and the side wall of the chute 4. The sliding member includes a slider 19. Limiting grooves 17 are opened on both sides of the bottom of the vehicle body 12 corresponding to the baffle 6. The sliders 19 are arranged on both sides of the baffle 6. The sliders 19 are slidably connected with the limiting grooves 17. A compression spring 18 is arranged between the end of the slider 19 corresponding to the side away from the rack 15 and the side wall of the limiting groove 17. An inclined plate 10 is arranged in the hopper 9. The inclined plate 10 can make the lime slide towards the discharge port 7. A push rod 11 is arranged on the vehicle body 12.

[0017] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, which are as follows:

[0018] According to the appended drawings of the specification Figures 1 - 3 It can be seen that when the utility model is in use, a person holds the push rod 11 by hand and drives the vehicle body 12 and the hopper 9 filled with lime on the vehicle body 12 to move through the wheels 1, and tries to move in a straight line as much as possible. Since the main shaft 16 is rotatably connected to the vertical plate 3 and fixedly connected to the wheels 1, when the wheels 1 move on the road surface, they rotate around the main shaft 16, thereby driving the main shaft 16 and the incomplete gear 2 at the center of the main shaft 16 to rotate. Since the rack 15 is matched with the chute 4 through the slide bar 13 at the bottom of the vehicle body 12, it can slide horizontally, and the toothed position of the incomplete gear 2 can mesh with it. Therefore, the rotation of the incomplete gear 2 can drive the rack 15 to move, so as to Figure 1For example, here it is necessary to push the cart to the left. The wheels 1 and the incomplete gear 2 rotate counterclockwise, thereby driving the rack 15 to move to the left. Since the left side of the bottom of the vehicle body 12 is slidably provided with a baffle 6 through a sliding member, the baffle 6 seals the discharge port 7 of the lime hopper 9 on the vehicle body 12. The leftward movement of the rack 15 causes it to push the baffle 6 to move to the left. Since there is a through port 5 on the baffle 6, pushing the push plate to the left can align the through port 5 with the discharge port 7, and the lime is discharged from the discharge port 7 and falls on the ground for marking. At this time, the toothless position of the incomplete gear 2 just corresponds to the rack 15, and the meshing is cancelled. The rack 15 is no longer subjected to the force given by the incomplete gear 2. Since a tension spring 14 is provided between the end of the slide bar 13 corresponding to the side away from the baffle 6 and the side wall of the chute 4, when the rack 15 moves to the left, the tension spring 14 stores energy. When disengaging from the incomplete gear 2, the restoring force of the tension spring 14 causes the rack 15 to reset to the rightmost position. At the same time, the sliding member can also return the baffle 6 to its initial position, that is, seal the discharge port 7. As the vehicle body 12 moves forward, the rotation of the wheels 1 continues to drive the incomplete gear 2 to rotate, and it meshes with the rack 15 again, repeating the above work. Every time the incomplete gear 2 rotates one circle, the rack 15 moves once and pushes the baffle 6 to move once, aligning the through port 5 with the discharge port 7 once to complete the lime feeding and marking work. When not meshing, the rack 15 and the baffle 6 return to their original positions. Moreover, every time the incomplete gear 2 rotates one circle, the vehicle body 12 travels an equal distance. Therefore, the present utility model achieves the purpose of equidistant lime feeding and marking through mechanical transmission. The device has low technical requirements for personnel, simple maintenance, and reduces the input cost.

[0019] Among them, the sliding member includes a slider 19. Limiting grooves 17 are provided on both sides of the bottom of the vehicle body 12 corresponding to the baffle 6. The slider 19 is arranged on both sides of the baffle 6, and the slider 19 is slidably connected with the limiting grooves 17. A compression spring 18 is provided between the end of the slider 19 corresponding to the side away from the rack 15 and the side wall of the limiting groove 17. During operation, the rack 15 pushes the baffle 6 to move to the left to store energy in the compression spring 18, and the moment when the incomplete gear 2 is not meshed with the rack 15 causes the baffle 6 to return to its original position. The cooperation between the slider 19 and the limiting groove 17 ensures the sealing of the discharge port 7 and also improves its stability during movement.

[0020] Among them, an inclined plate 10 is provided in the hopper 9, and the inclined plate 10 can make the lime slide towards the discharge port 7 to ensure stable lime feeding.

[0021] Among them, a push rod 11 is provided on the vehicle body 12 for convenient pushing by personnel. It can also be pulled by a powered cart or a power system can be added to the vehicle body 12 itself.

[0022] The diameter of the wheel 1 in the present utility model affects the distance traveled by each marking. Therefore, the personnel can adjust its diameter according to requirements. However, the adjustment range of the wheel 1 is limited. Here, through the prior art, a gear set can be added between the main shaft 16 and the incomplete gear 2 to change the transmission ratio between the wheel 1 and the incomplete gear 2, thereby changing the distance between the marking points, which can be achieved through the prior art.

[0023] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
