[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] Example: Please refer to Figures 1-5 This utility model provides a technical solution:
[0027] A badminton court marking device that can automatically display distance includes a mobile frame 1, an operating handle 2 fixedly installed at the rear end of the mobile frame 1, a gasoline engine 3 fixedly installed at the rear end of the mobile frame 1 and at the bottom of the operating handle 2, a paint storage box 4 fixedly installed at the middle of the top of the mobile frame 1, a transmission housing 5 fixedly installed on the right side of the mobile frame 1, and a marking frame 6 fixedly installed on the left side of the mobile frame 1. A dust removal component 7 and a marking box 8 are fixedly installed at the front and rear ends inside the marking frame 6, respectively.
[0028] First, in this embodiment, the specific structure of the gasoline engine 3 is as follows:
[0029] A drive wheel 501 is fixedly installed on the drive end of the gasoline engine 3 and inside the transmission housing 5. A movable wheel 502 is rotatably connected to the middle of the transmission housing 5. A first transmission wheel 503 is rotatably connected to the front end of the transmission housing 5. Both the drive wheel 501 and the first transmission wheel 503 are connected to the movable wheel 502 via a first transmission belt 504. A drive sprocket 505 is fixedly installed on the left end of the central shaft of the movable wheel 502. A movable shaft 506 is rotatably connected between the movable frame 1 and the marking frame 6. Movable wheels 507 are fixedly installed at both ends of the movable shaft 506. A transmission sprocket 508 is fixedly installed at the right end of 6. The transmission sprocket 508 is connected to the drive sprocket 505 via a chain 509. When marking lines on the badminton court, the gasoline engine 3 is started, and the drive wheel 501 and the first transmission belt 504 drive the moving wheel 502 to rotate. Then, the drive sprocket 505 and the chain 509 drive the transmission sprocket 508 to rotate, thereby driving the moving shaft 506 to rotate. The moving wheel 507 drives the moving frame 1 and the marking frame 6 to move, thus enabling continuous movement for marking operations and improving the efficiency of marking lines.
[0030] Furthermore, in this embodiment, the specific structure of the dust removal component 7 is as follows:
[0031] The dust removal assembly 7 includes a cleaning roller 701 rotatably connected to the bottom of the front end of the marking frame 6. A dust suction hood 702 is fixedly installed at the front end of the marking frame 6 and above the cleaning roller 701. A drive shaft 703 is rotatably connected to the top of the dust suction hood 702. An exhaust fan 704 is fixedly installed inside the dust suction hood 702 and at the left end of the drive shaft 703. A dust exhaust pipe 705 is fixedly installed on the left side of the dust suction hood 702 and outside the exhaust fan 704. When the moving wheel 502 rotates, it drives the first drive wheel 503 to rotate under the drive of the first drive belt 504. The first drive wheel 503 drives the cleaning roller 701 and the drive shaft 703 to rotate. Thus, before the marking box 8 marks the lines, the cleaning roller 701 cleans the dust on the ground, and the drive shaft 703 drives the exhaust fan 704 to rotate, guiding the cleaned dust into the interior of the dust suction hood 702. Finally, the dust is discharged through the dust exhaust pipe 705, thereby avoiding affecting the coating effect and ensuring the marking quality.
[0032] Then, a directional wheel 101 is rotatably connected to the front end of the bottom of the mobile frame 1. When the mobile frame 1 moves, the direction of movement of the mobile frame 1 can be controlled by holding the operating handle 2 and through the directional wheel 101.
[0033] Furthermore, a gear shift lever 201 is installed on the left end of the operating handle 2. The gear shift lever 201 is connected to the throttle valve of the gasoline engine 3 via a cable. By rotating the gear shift lever 201, the cable changes the opening of the throttle valve of the gasoline engine 3, thereby adjusting the intake air volume of the gasoline engine 3, thus controlling the speed of the gasoline engine 3, and consequently controlling the movement speed of the moving frame 1.
[0034] The paint storage box 4 has a lid 401 hinged to its top, and a cover 402 is installed on the top of the marking box 8. The bottom of the paint storage box 4 is fixedly connected to the cover 402 via a connecting pipe 403. A discharge roller 510 is fixedly installed on the outside of the moving shaft 506 and inside the marking box 8. After the lid 401 is opened, marking paint is added to the inside of the paint storage box 4 and introduced into the inside of the marking box 8 through the connecting pipe 403. When the moving shaft 506 rotates, the discharge roller 510 rolls inside the marking box 8. The paint is evenly discharged to the bottom of the marking box 8 for marking operation under the rolling of the discharge roller 510.
[0035] Secondly, a second transmission wheel 511 is fixedly installed on the right end of both the cleaning roller 701 and the transmission shaft 703, and the central shaft of one set of second transmission wheels 511 is fixedly connected to the central shaft of the first transmission wheel 503. The two sets of second transmission wheels 511 are connected by a second transmission belt 512. When the first transmission wheel 503 rotates, it drives the upper second transmission wheel 511 to rotate. Under the transmission of the second transmission belt 512, the cleaning roller 701 and the transmission shaft 703 rotate, so that the dust on the ground can be automatically cleaned during the movement of the moving frame 1, thereby avoiding affecting the coating effect and ensuring the quality of the marking.
[0036] Finally, a wireless encoder 513 is fixedly installed on the left end of the moving shaft 506 and on the outside of the moving frame 1, and a distance display screen 514 is fixedly installed on the top of the operating handle 2. When the moving shaft 506 rotates, the wireless encoder 513 detects the moving distance in real time. The wireless encoder 513 has a built-in wireless communication module that transmits the data to the distance display screen 514, so that the distance can be automatically displayed during the line drawing process.
[0037] In this embodiment, the specific implementation scenario is as follows: When marking lines on a badminton court, the gasoline engine 3 is started, and the driving wheel 501 and the first transmission belt 504 drive the movable wheel 502 to rotate. Subsequently, the driving sprocket 505 and the chain 509 drive the transmission sprocket 508 to rotate, thereby driving the movable shaft 506 to rotate. The movable wheel 507 drives the movable frame 1 and the marking frame 6 to move. After the box cover 401 is opened, marking paint is added to the paint storage box 4 and introduced into the marking box 8 through the connecting pipe 403. When the movable shaft 506 rotates, the discharge roller 510 rolls inside the marking box 8. The paint is evenly discharged to the bottom of the marking box 8 under the rolling of the discharge roller 510 for marking operation. When the movable wheel 502 rotates, the first transmission belt 504... The transmission mechanism drives the first transmission wheel 503 to rotate, which in turn drives the cleaning roller 701 and the transmission shaft 703 to rotate. Before marking lines in the marking box 8, the cleaning roller 701 cleans the dust on the ground, and the transmission shaft 703 drives the exhaust fan 704 to rotate, guiding the collected dust into the dust collection hood 702 and finally discharging it through the dust exhaust pipe 705. Simultaneously, when the moving shaft 506 rotates, the wireless encoder 513 detects the moving distance in real time. The wireless encoder 513 has a built-in wireless communication module that transmits data to the distance display screen 514, automatically displaying the distance during the marking process. The entire operation is simple and convenient. This invention, through its design, allows for continuous movement during marking operations, improving marking efficiency while avoiding impacts on the coating effect and ensuring marking quality.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
