[0023] Depend on Figures 1 to 5 The present invention discloses a transmission mechanism for a line marking machine based on an upper frame, comprising an engine 1 and a pump 2. The engine 1 is fixedly installed on the top of the line marking machine frame 3. A support frame 4 is welded to the top of the line marking machine frame 3. The pump 2 is fixedly connected to the top of the support frame 4. A drive pulley 5 is provided on the side of the engine 1, and a driven pulley 6 is provided on the side of the pump 2. The drive pulley 5 and the driven pulley 6 are connected by a belt 7. A ventilated heat dissipation cover 8 is fixedly provided on one side of the support frame 4. The support frame 4 is composed of two stainless steel square tubes 9, a support horizontal plate 10, a stainless steel support vertical plate 11, and a support beam 12. The stainless steel square tubes 9 are welded to one side of the line marking machine frame 3, the stainless steel support vertical plate 11 is welded to the other side of the line marking machine frame 3, the support beam 12 is welded between the two stainless steel square tubes 9, and the support horizontal plate 10 is fixedly connected to the top of the support beam 12 and the stainless steel support vertical plate 11 by a group of bolts 13.

[0024] The support frame 4 is fixedly connected to the top of the line marking machine frame 3, so that the pump 2 is located directly above the engine 1, avoiding the top-heavy situation of the line marking machine and improving the stability of the line marking machine. The drive pulley 5, driven pulley 6 and belt 7 realize power transmission, so that the pump 2 can be driven by the engine 1. The ventilated heat dissipation cover 8 can cover the drive pulley 5, driven pulley 6 and belt 7 to prevent the drive pulley 5, driven pulley 6 and belt 7 from being exposed and affecting safety. The ventilated heat dissipation cover 8 is a ventilated structure, so as not to affect the normal heat dissipation of the engine 1 and pump 2. The support cross plate 10 is connected to the support cross beam 12 and the stainless steel support vertical plate 11 by bolt group 13, so that the support cross plate 10 can be disassembled separately.

[0025] Depend on Figures 2 to 5 As shown, a mounting base 14 is welded to the bottom of the pump 2. The mounting base 14 is connected to the support plate 10 by a number of bolt groups 2 15. The support plate 10 has two strip-shaped through grooves 16 that match the bolt groups 2 15. The top of the support plate 10 has a strip-shaped groove 17. The bottom of the inside of the strip-shaped groove 17 has a number of limiting tooth grooves 18. The bottom of the mounting base 14 is fixedly provided with a limiting toothed rack 19 that matches the strip-shaped groove 17 and the limiting tooth grooves 18.

[0026] The combination of bolt group 2 15 and strip groove 16 allows for fine adjustment of the installation position of pump 2. Limiting tooth groove 18 and limiting toothed rack 19 can achieve the limiting function, thereby improving the stability of pump 2 after installation and preventing displacement.

The two strip-shaped clamping plates 23 are welded to the bottom ends of both sides of the mesh cover 22 and inserted into the vertical limiting slots 20. Several threaded holes 24 matching the bolts 21 are provided on the strip-shaped clamping plates 23.

[0028] The vertical limiting slot 20 and the strip-shaped snap-fit ​​plate 23 can achieve snap-fit ​​connection. The bolt 21 and the threaded hole 24 can limit and lock the strip-shaped snap-fit ​​plate 23, which improves the installation stability of the ventilated heat dissipation cover 8 and also facilitates the disassembly and assembly of the ventilated heat dissipation cover 8.

[0029] During operation, by mounting the pump directly above the engine via a support frame, the top-heavy nature of traditional marking machines is avoided, thus preventing instability. A ventilated heat dissipation shroud provides lateral protection for the drive pulley, driven pulley, and belt, preventing them from being exposed and compromising safety. The installation position of the pump can be fine-tuned by the mounting base, bolt group two, strip-shaped through grooves, strip-shaped recesses, limiting tooth grooves, and limiting toothed racks, improving adaptability and stability after installation and preventing lateral displacement due to vibration. The vertical limiting slots, bolts, and the ventilated heat dissipation shroud consisting of a mesh cover and two strip-shaped clamping plates facilitate easy disassembly.
