Description

Technical Field

[0001] This utility model relates to the field of line marking technology, and in particular to a line marking device for sports events. Background Technology

[0002] A sports event line marker is a device specifically designed for marking lines on sports fields, primarily used to mark playing areas and boundaries on various sports surfaces. This type of line marker typically includes components such as a platform, push-pull rod, marking mechanism, and wheels, and its design emphasizes ease of operation and accuracy in line marking.

[0003] The main components of a sports event line marking device include a platform, push-pull rods, a marking mechanism, and wheels. The marking mechanism seals lime slurry in a hopper through a sealing plate and a pressure plug. Gas is injected into the hopper by the reciprocating motion of a piston inside a cylinder and the action of a one-way valve, causing the lime slurry to be sprayed onto the ground through a discharge head under pressure.

[0004] Its use has the following disadvantages:

[0005] 1. The discharge speed of lime slurry does not match the travel speed, making it impossible to guarantee the uniformity of the marking width;

[0006] 2. The output of lime slurry cannot be flexibly adjusted according to actual usage. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a sports event marking device that matches the lime slurry discharge speed with the travel speed to ensure the uniformity of the marking and allows for flexible adjustment of the marking width according to actual use.

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a marking device for sports events, comprising a base plate and a hopper, wherein the hopper is located above the base plate, and the lower end face of the hopper is conical.

[0009] The hopper is connected to the base plate via a bracket, and a feeding pipe is provided on the lower end face of the hopper. A feeding screw is rotatably connected inside the feeding pipe.

[0010] The base plate is provided with a feeding pipe at one end, the upper end of the feeding pipe is connected to the feeding pipe, the upper end of the feeding pipe is provided with an opening adjustment component, the opening adjustment component adjusts the feeding amount of the feeding pipe, and the other end of the base plate is provided with a transmission component.

[0011] The bottom end face of the base plate is symmetrically provided with universal wheels at one end corresponding to the feeding pipe. The bottom end face of the base plate is symmetrically provided with support plates at the position corresponding to the transmission component. The support plates are rotatably connected by a rotating shaft. The rotating shaft is provided with rollers at both ends. The rotating shaft drives the feeding screw to rotate through the transmission component.

[0012] The upper surface of the base plate is symmetrically provided with upright plates, and push rods are provided between the upper surfaces of the upright plates.

[0013] Furthermore, the opening adjustment component includes a frame, a stop block, and an adjusting bolt. The frame is provided on the inner surface of the upper end of the feed tube opposite to the feeding tube. The stop block is slidably connected inside the frame, and the adjusting bolt is rotatably connected inside the frame. The adjusting bolt protrudes from the feed tube and is threadedly connected to the stop block.

[0014] Furthermore, the transmission component includes a transmission rod, a connecting rod, and a gear set. The transmission rod is rotatably connected to the base plate, the connecting rod is connected to the feeding screw and protrudes from the feeding pipe, and the gear set includes gear one, gear two, gear three, and gear four. Gear one is mounted on the rotating shaft, gear two and gear three are respectively mounted at the upper and lower ends of the transmission rod, and gear four is mounted at the end of the connecting rod away from the feeding screw. Gear one and gear three mesh, and gear four and gear two mesh.

[0015] Furthermore, gear one, gear two, gear three and gear four are all bevel gears.

[0016] Furthermore, a sealing plate is provided at the upper opening of the hopper, and one end of the sealing plate is hinged to the opening of the hopper.

[0017] Furthermore, the upper end of the upright plate is bent away from the hopper.

[0018] The advantages of this utility model compared with the prior art are as follows:

[0019] 1. During the movement, the roller drives the rotating shaft to rotate, and the rotating shaft drives the feeding screw in the feeding pipe to rotate through the transmission component. The feeding screw feeds the lime slurry in the hopper to the discharge pipe, so that the discharge speed of the lime slurry matches the movement speed, ensuring the uniformity of the marking.

[0020] 2. The discharge rate of the feed pipe is adjusted by the opening adjustment component, thereby adjusting the amount of lime slurry passing through the feed pipe and thus flexibly controlling the width of the marking. Attached Figure Description

[0033] The upper end of the base plate 1 is symmetrically provided with upright plates 11, and push rods 12 are provided between the upper ends of the upright plates 11.

[0034] In use, the base plate 1 is pushed by the push rod 12 at the top of the upright plate 11, the universal wheel 7 adjusts the direction of travel, and the roller 10 rotates to drive the rotating shaft 9 to rotate between the support plates 8.

[0035] Combined with appendix Figure 1-3 The hopper 2 is connected to the base plate 1 via the bracket 3. The lower end face of the hopper 2 is provided with a feeding pipe 4, and a feeding screw 5 is rotatably connected inside the feeding pipe 4.

[0036] The base plate 1 is provided with a feeding pipe 6 at one end, the upper end of the feeding pipe 6 is connected to the feeding pipe 4, and the base plate 1 is provided with a transmission component at the other end.

[0037] The rotating shaft 9 drives the feeding screw 5 to rotate through a transmission component. The transmission component includes a transmission rod 16, a connecting rod 17, and a gear set. The transmission rod 16 is rotatably connected to the base plate 1. The connecting rod 17 is connected to the feeding screw 5 and protrudes from the feeding pipe 4. The gear set includes gear one 18, gear two 19, gear three 20, and gear four 21. Gear one 18 is mounted on the rotating shaft 9.

Gear four 21 is mounted on the end of the connecting rod 17 away from the feeding screw 5. Gear one 18 and gear three 20 mesh, and gear four 21 and gear two 19 mesh.

[0038] During the movement of the marking device, the roller 10 rotates, driving the rotating shaft 9 to rotate. The rotating shaft 9 drives the gear 18 to rotate, which in turn drives the gear 20 meshing with it to rotate. The gear 20 drives the transmission rod 16 to rotate, which in turn drives the gear 19 to rotate. The gear 29 then drives the gear 21 meshing with it to rotate. The gear 21, through the connecting rod 17, drives the feeding screw 5 to rotate. The feeding screw 5 transports the lime slurry at the lower end of the hopper 2. The feeding screw 5 delivers the lime slurry through the feeding pipe 4 to the discharge pipe 6, where it discharges the lime slurry. This achieves a match between the moving speed and the discharge speed, ensuring the uniformity of the marking.

[0039] Combined with appendix Figure 3 The upper end of the feeding pipe 6 is provided with an opening adjustment component, which adjusts the feeding amount of the feeding pipe 6;
