[0025] In the above technical solution, by utilizing the first transmission component, when the frame 11 is pushed to move (the wheel 18 is in forward rotation at this time), the push plate 309 on the threaded seat 306 can be used to push the powder material in the receiving barrel 24, thereby enabling the powder material in the receiving barrel 24 to fall to the ground through the discharge pipe 22, thereby achieving the effect of marking the road; by utilizing the push plate 309 on the threaded seat 306, the push plate 309 is reciprocated and slid under the action of the first transmission component, so that The push plate 309 is in a negative pressure state when sliding in the reverse direction, so that the push plate 309 can absorb the powder material in the storage barrel 15, so that the powder material in the storage barrel 15 can fall into the receiving barrel 24 through the feeding pipe 16, and the push plate 309 is in a negative pressure state when sliding in the forward direction, so that the push plate 309 can push the powder material in the receiving barrel 24, so that the powder material in the receiving barrel 24 can fall to the ground through the discharge pipe 22, and then by using the reciprocating sliding of the push plate 309, the receiving barrel can be connected. 24 can be automatically loaded and unloaded; by utilizing the second transmission component, when the frame 11 is pushed to move (the wheel 18 is in reverse rotation at this time), the push plate 309 can slide in the reverse direction for a certain distance, so that the push plate 309 can block the nozzle of the feeding tube 16, thereby blocking the flow of the powder material in the storage barrel 15, and thereby preventing the powder material in the marking barrel 21 from falling to the ground through the discharge barrel; therefore, by utilizing the mutual cooperation between the above components, the When the wheel 18 moves in the forward direction, it can drive the powder material in the marking drum 21 to fall to the ground through the discharge pipe 22, thereby achieving the effect of road marking; and when the wheel 18 on the frame 11 moves in the reverse direction, it can stop pushing the powder material in the marking drum 21, thereby achieving the effect of stopping the road marking; thus, the marking equipment does not need to be driven separately, and the marking equipment can be controlled only by the forward and reverse rotation of the wheel 18, thereby facilitating the use of the marking equipment by the staff and reducing the production cost of the marking equipment.

[0026] Specifically, a feeding pipe 16 is provided on the top end surface of the storage barrel 15 .

Then, with the help of the push plate 309, the receiving barrel 24 can slide relative to the sliding base 23 in the direction close to the discharge pipe 22, so that the receiving barrel 24 can protrude to the distance of one end of the sliding base 23, and the powder material in the receiving barrel 24 can pass through the discharge pipe 22 and fall to the ground.

[0031] In the above technical solution, by utilizing the driving shaft 301, when the frame 11 is pushed to move, the first bevel gear 302 on the driving shaft 301 is rotated by virtue of the rotation of the wheel 18 (the wheel 18 rotates in the positive direction), and then the adjusting snap ring 3031 on the threaded rod 303 is engaged with the first fixed snap ring 3041 on the second bevel gear 304 and the second fixed snap ring 3051 on the third bevel gear 305 respectively, so that when the driving shaft 301 rotates unidirectionally (i.e., in the positive direction), the rotation direction of the threaded rod 303 can be changed, thereby achieving the effect of enabling the threaded seat 306 to reciprocate along the axial direction of the threaded rod 303, and then by utilizing the push plate 309 on the threaded seat 306, the powder material in the docking barrel 24 can be loaded and pushed.

[0032] Specifically, a threaded barrel 307 is rotatably disposed on the threaded seat 306 , and a screw rod 308 is threadedly connected in the threaded barrel 307 .

[0033] In the above technical solution, by utilizing the threaded barrel 307 on the threaded seat 306, the position of the push plate 309 on the screw 308 can be adaptively adjusted, so that the sliding stroke of the push plate 309 can be adjusted, and the offset distance between the sliding base 23 and the receiving barrel 24 during the sliding process can be adjusted, thereby controlling the discharge amount of powder material in the receiving barrel 24, thereby meeting different usage scenarios.

[0034] Specifically, a guide rod 311 is fixedly installed between the mounting seat 310 and the frame 11, and the threaded seat 306 is slidably set on the guide rod 311; two fixing rings 312 are fixedly installed on the circumferential surface of the guide rod 311, and abutment plates 313 are slidably set on the sides of the two fixing rings 312 close to each other, and a second spring 3102 is set between the abutment plate 313 and the fixing ring 312, and the threaded seat 306 is slidably set between the two abutment plates 313.

[0035] In the above technical solution, by utilizing the guide rod 311, the sliding direction of the threaded seat 306 is restricted, and by utilizing the threaded rod 303 to drive the movement of the threaded seat 306, the threaded seat 306 can abut against the abutment plate 313 on the guide rod 311 during the movement, thereby achieving the effect of sliding the threaded rod 303 on the driving frame 11 by means of the elastic force of the third spring 314, so that the adjustment snap ring 3031 on the threaded rod 303 can respectively engage with the first fixed snap ring 3041 on the second bevel gear 304 and the second fixed snap ring 3051 on the third bevel gear 305, thereby achieving the effect of restricting the rotation direction of the threaded rod 303.

[0036] Specifically, a mounting seat 310 is fixedly installed on the frame 11, and the marking cylinder 21 is fixedly installed on the mounting seat 310; a limiting ball 3101 is slidably arranged on the mounting seat 310, and a third spring 314 is arranged between the limiting ball 3101 and the mounting seat 310, and the two ends of the third spring 314 are respectively connected to the mounting seat 310 and the limiting ball 3101; an adjusting cylinder 3032 is also slidably arranged on the mounting seat 310, and the adjusting cylinder 3032 is fixedly installed on the threaded rod 303, and a first adjusting groove 3033 and a second adjusting groove 3034 that cooperate with the limiting ball 3101 are opened on the adjusting cylinder 3032.

[0037] In the above technical solution, by utilizing the limiting ball 3101 on the mounting seat 310 and the first adjusting groove 3033 and the second adjusting groove 3034 on the adjusting cylinder 3032, when the threaded rod 303 slides, the limiting ball 3101 on the mounting seat 310 can slide along the first adjusting groove 3033 and the second adjusting groove 3034 on the adjusting cylinder 3032 respectively, thereby achieving the effect of limiting the position of the threaded rod 303 after adjustment, and avoiding the situation where the threaded rod 303 slides in position due to the shaking of the threaded rod 303, thereby affecting the reciprocating sliding effect of the push plate 309 on the threaded seat 306.

[0038] Specifically, the second transmission assembly includes a connecting plate 401 fixedly mounted on the frame 11, the driving shaft 301 is rotatably mounted on the connecting plate 401, a movable cylinder 402 is movably mounted on the connecting plate 401, a first coupling disk 403 is fixedly mounted on the end surface of the movable cylinder 402, a fourth spring 404 is arranged between the first coupling disk 403 and the connecting plate 401, a second coupling disk 405 matched with the first coupling disk 403 is fixedly mounted on the driving shaft 301; a worm 406 is rotatably mounted on the connecting plate 401, the worm 406 is slidably sleeved on the movable cylinder 402, a first rotating rod 407 is rotatably mounted on the frame 11, and a worm wheel 408 matched with the worm 406 is fixedly mounted on one end of the first rotating rod 407.

[0039] Furthermore, a fourth bevel gear 409 is fixedly installed on the other end of the first rotating rod 407, a second rotating rod 410 is rotatably installed on the frame 11, a fifth bevel gear 411 meshing with the fourth bevel gear 409 is fixedly installed on the second rotating rod 410, and a limiting component for limiting the unidirectional rotation of the first rotating rod 407 is provided on the fourth bevel gear 409; a circular gear 412 is also fixedly installed on the second rotating rod 410, and a rack 413 meshing with the circular gear 412 is fixedly installed on the threaded seat 306.

[0040] In the above technical solution, by using the first coupling disc 403 and the second coupling disc 405, when the frame 11 is pushed to move, the first coupling disc 403 on the drive shaft 301 can slide to a state of meshing with the second coupling disc 405, so that with the help of the rotation of the wheel 18 (the wheel 18 rotates in the opposite direction), the worm 406 can be driven to rotate when the drive shaft 301 rotates in one direction (i.e., in the opposite direction), and the first rotating rod 407 on the frame 11 is rotated by the mutual cooperation between the worm wheel 408 and the worm 406, so that the fourth bevel gear 409 and the fifth bevel gear 411 are mutually cooperated ... The second rotating rod 410 rotates, so through the mutual cooperation between the circular gear 412 on the second rotating rod 410 and the rack 413 on the threaded seat 306, the threaded seat 306 can slide under the action of the rack 413, so that the push plate 309 in the marking cylinder 21 can move a distance away from the discharge cylinder, that is, the push plate 309 slides to a position where it can block the nozzle of the feed pipe 17, thereby limiting the discharge of powder material in the storage cylinder 15. Therefore, by utilizing the wheel 18 to drive the driving shaft 301 to rotate in the opposite direction, the discharge of powder material can be stopped, and the marking equipment can be moved in position after the discharge is stopped.

[0041] Specifically, the limiting assembly includes a fixing plate 4091 fixedly mounted on the first rotating rod 407 , a ratchet 4092 is rotatably provided on the fixing plate 4091 , and a ratchet 4093 matched with the ratchet 4092 is fixedly mounted on the fourth bevel gear 409 .

[0042] In the above technical solution, by utilizing the pawl 4092 on the first rotating rod 407 and the ratchet 4093 on the fourth bevel gear 409, the rotation direction of the first rotating rod 407 can be limited. Therefore, when the driving shaft 301 rotates forward under the drive of the wheel 18, the sliding of the threaded seat 306 can be avoided as much as possible to avoid the conflict with the operation of the worm wheel 408 and the worm 406.

[0043] Specifically, movable latch teeth 414 are slidably provided at both ends of the rack 413 , and a plurality of fifth springs 415 are provided between the movable latch teeth 414 and the rack 413 .

[0044] In the above technical solution, by utilizing the movable latch tooth 414, the rack 413 on the threaded seat 306 is moved to a certain position under the action of the circular gear 412 (that is, after the push plate 309 in the marking cylinder 21 blocks the pipe mouth of the feed pipe 17), and by utilizing the continuous rotation of the circular gear 412, the rack 413 can be effectively separated from the circular gear 412, so that when the wheel 18 is continuously rotating in the reverse direction, the push plate 309 can always stop at the pipe mouth of the feed pipe 17. Therefore, when the marking equipment is adjusted to a certain position, the marking cylinder 21 can always be kept in a stopped state, and by utilizing the mutual cooperation between the movable latch tooth 414 and the fifth spring 415, when the drive shaft 301 is rotating in the forward direction of the wheel 18, the rack 413 can be driven to quickly engage with the circular gear 412 again.

[0045] Specifically, a limit rod 416 is fixedly mounted on the rack 413 , and the movable latch 414 is slidably disposed on the limit rod 416 . Both ends of the fifth spring 415 are respectively fixedly mounted on the rack 413 and the movable latch 414 , and the fifth spring 415 is sleeved on the limit rod 416 .

[0046] In the above technical solution, by utilizing the limiting rod 416 , the sliding direction of the movable latching tooth 414 can be limited.

[0047] Working principle: when the frame 11 needs to be pushed to move and the road is marked, the driving shaft 301 is used to make the frame 11 move, and the first bevel gear 302 on the driving shaft 301 rotates by virtue of the rotation of the wheel 18 (the wheel 18 rotates in the positive direction), and then the adjusting snap ring 3031 on the threaded rod 303 is engaged with the first fixed snap ring 3041 on the second bevel gear 304 and the second fixed snap ring 3051 on the third bevel gear 305, so that when the driving shaft 301 rotates in one direction (i.e., in the positive direction), the rotation direction of the threaded rod 303 can be changed, so that the threaded seat 306 can slide back and forth along the axial direction of the threaded rod 303, and then the push plate 309 on the threaded seat 306 can be used to load and push the powder material in the docking barrel 24; The guide rod 311 is used to limit the sliding direction of the threaded seat 306, and the threaded rod 303 is used to drive the threaded seat 306 to move, so that the threaded seat 306 can abut against the abutment plate 313 on the guide rod 311 during the movement, so that the threaded rod 303 on the driving frame 11 can be driven to slide by the elastic force of the third spring 314, so that the adjusting snap ring 3031 on the threaded rod 303 can respectively engage with the first fixing snap ring 3041 on the second bevel gear 304 and the second fixing snap ring 3051 on the third bevel gear 305, thereby limiting the rotation direction of the threaded rod 303. When the push plate 309 slides in the marking cylinder 21, the push plate 309 and the receiving cylinder 24 abut against each other, thereby driving the receiving cylinder 24 to slide along the sliding base 23, thereby overcoming the elastic force of the first spring 25, so that the powder material in the receiving cylinder 24 can pass through the discharge hole on the receiving cylinder 24, so that the powder material can fall to the ground along the discharge cylinder, thereby achieving the effect of marking the road; and by utilizing the threaded cylinder 307 on the threaded seat 306, the position of the push plate 309 on the screw 308 can be adaptively adjusted, so that the sliding stroke of the push plate 309 can be used to adjust the offset distance between the sliding base 23 and the receiving cylinder 24 during the sliding process, thereby controlling the discharge amount of the powder material in the receiving cylinder 24, thereby meeting different usage scenarios; When the marking drum 21 is not used to mark the road, that is, when the workstation of the marking equipment needs to be adjusted accordingly, the first coupling disc 403 and the second coupling disc 405 are used to make the first coupling disc 403 on the drive shaft 301 slide to a state of meshing with the second coupling disc 405 when the frame 11 is pushed to move. Therefore, with the help of the rotation of the wheel 18 (the wheel 18 rotates in the opposite direction), the unidirectional (i.e., reverse) rotation of the drive shaft 301 can drive the worm 406 to rotate, and the mutual engagement between the worm wheel 408 and the worm 406 The first rotating rod 407 on the vehicle frame 11 is rotated by the cooperation between the fourth bevel gear 409 and the fifth bevel gear 411, so that the second rotating rod 410 on the vehicle frame 11 is rotated, so that the circular gear 412 on the second rotating rod 410 and the rack 413 on the threaded seat 306 are cooperated with each other, so that the threaded seat 306 can slide under the action of the rack 413, so that the push plate 309 in the marking barrel 21 can move to a distance away from the unloading barrel, that is, the push plate 309 slides to a distance that can The position of the nozzle of the feed pipe 17 is blocked, thereby limiting the discharge of the powder material in the storage barrel 15. Therefore, by using the wheel 18 to drive the driving shaft 301 to rotate in the opposite direction, the discharge of the powder material can be stopped, and the marking device can be moved after the discharge is stopped. By using the movable latch 414, the rack 413 on the threaded seat 306 is moved to a certain position under the action of the circular gear 412 (that is, after the push plate 309 in the marking barrel 21 blocks the nozzle of the feed pipe 17), and the circular gear 412 is used to The rack 413 is continuously rotated, so that the rack 413 can be effectively separated from the circular gear 412, so that when the wheel 18 is continuously rotating in the reverse direction, the push plate 309 can always stop at the pipe mouth of the feed pipe 17, so when the marking device is adjusted to a station, the marking drum 21 can always be kept in a stopped state, and by utilizing the mutual cooperation between the movable latch tooth 414 and the fifth spring 415, when the drive shaft 301 is rotating in the forward direction of the wheel 18, the rack 413 can be driven to quickly mesh with the circular gear 412 again; Therefore, by utilizing the mutual cooperation between the above-mentioned components, when the wheels 18 on the frame 11 move in the forward direction, they can drive the powder material in the marking drum 21 to fall to the ground through the discharge pipe 22, thereby achieving the effect of road marking; and when the wheels 18 on the frame 11 move in the reverse direction, they can stop pushing the powder material in the marking drum 21, thereby achieving the effect of stopping the road marking; and thus, the marking equipment does not need to be driven separately, and the marking equipment can be controlled only by the forward and reverse rotation of the wheels 18, thereby facilitating the use of the marking equipment by the staff and reducing the production cost of the marking equipment. The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
