Description

Technical Field

[0001] This application relates to the technical field of lawn laying equipment, and in particular to a scraper drive device for an automatic lawn laying device for natural grass football fields. Background Technology

[0002] In today's booming sports industry, natural grass football fields, with their excellent athletic performance and comfortable feel, have become the preferred venue for many professional competitions and everyday sports activities. The quality of the natural grass installation directly affects the user experience of the football field and the performance of the athletes. Early natural grass installation relied primarily on manual labor. Workers had to manually carry rolls of turf, unfold them, lay them on the ground, and then use tools to level and compact them. This method was not only labor-intensive but also extremely inefficient; installing the turf for a standard football field often required dozens of people and several days.

[0003] With technological advancements, some rudimentary turf laying equipment has emerged. This equipment typically consists of a simple support frame mounted on a flatbed cart to hold turf rollers. The cart is pushed forward manually, while manual assistance is provided for spreading and laying the turf. The support frame itself is simple, constructed from a few welded steel pipes, making it prone to wobbling as the turf rollers rest on it. This results in twisting and wrinkling of the turf during laying. Furthermore, this equipment lacks guiding and restraining structures for the turf, causing it to easily shift to either side, leading to inconsistent laying widths. This necessitates extensive manual correction and adjustment afterward, increasing costs and compromising the quality of the turf laying. Utility Model Content

[0004] To achieve stable and efficient turf laying, this application provides a scraper drive device for an automatic turf laying device for natural grass football fields.

[0005] The scraper drive device for an automatic natural grass football field laying device provided in this application adopts the following technical solution:

A scraper assembly is mounted at the front of the mobile vehicle and rotatably connected to the mobile vehicle. An electric cylinder for driving the scraper assembly to rotate is mounted on the mobile vehicle. Two sets of limit stops are symmetrically mounted in the scraper assembly and slidably connected to the scraper assembly. An auxiliary seat is fixedly mounted on the lower end face of the scraper assembly, and a drive component for adjusting the distance between the two sets of limit stops is provided on the auxiliary seat.

[0007] By adopting the above technical solution, the mobile vehicle ensures flexible movement during the laying process, the roller seat ensures stable placement and rolling of the turf rolls, and the scraper assembly provides stable guidance and support during the rolling process, ensuring stable turf laying. Furthermore, the scraper assembly can be adjusted and rotated via an electric cylinder according to actual conditions. An auxiliary seat ensures better installation and connection of the drive unit and electric cylinder. Additionally, two sets of limit stops are symmetrically installed in the scraper assembly, and the distance between the two sets of limit stops can be adjusted via the drive unit, facilitating better limiting of different sides of the turf.

[0008] Optionally, the placement roller seat includes a frame and two sets of support rollers, the support rollers are mounted in the frame, and both ends of the support rollers are rotatably connected to the frame.

[0017] By adopting the above technical solution, the driving component uses a combination of a double-ended screw and a motor, with the motor driving the double-ended screw to rotate. Since the threaded sleeve on the bending slide plate cooperates with the double-ended screw, when the double-ended screw rotates, the two sets of limit stops will move in opposite directions or away from each other along the scraper assembly, thereby conveniently adjusting the distance between the two sets of limit stops to adapt to the laying requirements of turf of different widths.

[0018] Optionally, the lower end face of the main board is provided with an auxiliary shaft seat for the rotatable mounting of the double-ended screw, and the auxiliary shaft seat is fixedly connected to the main board.

[0019] By adopting the above technical solution, the auxiliary bearing on the lower end face of the main board provides stable rotation support for the double-ended screw, ensuring the stability of the double-ended screw during rotation, reducing vibration and noise, and improving the working efficiency and service life of the drive components.

[0020] Optionally, the bending slide plate is provided with a threaded sleeve that mates with the double-ended screw, and the threaded sleeve is integrally formed with the bending slide plate.

[0021] By adopting the above technical solution, the threaded sleeve on the bending slide plate is integrally formed with the bending slide plate. This design makes the connection between the threaded sleeve and the bending slide plate more solid, and can better withstand the force generated when the double-headed screw rotates, ensuring the accuracy and stability of the movement of the limit stop.

[0022] In summary, this application includes at least one of the following beneficial technical effects: By utilizing the movement of a mobile vehicle and the cooperation of the scraper assembly, turf can be quickly laid on a football field.

Furthermore, two sets of limit brackets 4 are symmetrically installed in the scraper assembly 3, and the distance between the two sets of limit brackets 4 can be adjusted by the drive unit 6, facilitating better limiting of different sides of the turf.

[0032] Reference Figure 1 As shown, the placement roller seat 2 includes a seat frame 21 and two sets of support rollers 22. The support rollers 22 are installed in the seat frame 21, and both ends of the support rollers 22 are rotatably connected to the seat frame 21. The design of the seat frame 21 and support rollers 22 of the placement roller seat 2 can stably place the turf rollers. The rotatable connection between the support rollers 22 and the seat frame 21 allows the turf rollers to rotate smoothly during the laying process, reducing the resistance when the turf is spread out and ensuring the continuity and flatness of the turf laying. The seat frame 21 provides a stable placement platform for the turf rollers, preventing the turf rollers from shaking or falling off during the movement of the moving vehicle 1.

[0033] Reference Figure 2 , Figure 3 and Figure 4 As shown, the scraper assembly 3 includes a main plate 31 and connecting ear plates 32. The connecting ear plates 32 are fixedly installed on both sides of the main plate 31 and are rotatably connected to the mobile vehicle 1. The scraper assembly 3 is rotatably connected to the mobile vehicle 1 through the connecting ear plates 32. This design allows the scraper assembly 3 to flexibly adjust its angle. Driven by the electric cylinder 10, the scraper assembly 3 can rotate, adjusting the contact angle between the scraper and the ground according to different paving requirements, thereby better adapting to the paving of turf of different thicknesses and textures and improving the paving effect.

[0034] Reference Figure 2 and Figure 4As shown, the limiting bracket 4 includes a vertical plate 41 and a bending slide plate 42. The bending slide plate 42 is mounted on the head of the vertical plate 41 and is fixedly connected to the vertical plate 41. The structure of the vertical plate 41 and the bending slide plate 42 of the limiting bracket 4 allows the vertical plate 41 to limit the sides of the turf, preventing it from shifting to either side during installation and ensuring a consistent width. The bending slide plate 42 is slidably connected to the scraper assembly 3, allowing the limiting bracket 4 to move flexibly on the scraper assembly 3, facilitating adjustments based on the actual width of the turf.

[0035] Reference Figure 3 and Figure 5 As shown, the auxiliary base 5 includes a bending plate 51 and a connecting seat 52 connected to the output end of the electric cylinder 10. The bending plate 51 is fixedly installed on the lower end face of the scraper assembly 3, and the connecting seat 52 is fixedly installed on one end of the bending plate 51.

This integral forming design makes the connection between the threaded sleeve 421 and the bending slide plate 42 more robust, better able to withstand the force generated when the double-ended screw 61 rotates, and ensures the accuracy and stability of the movement of the limit stop 4.

[0037] The implementation principle of the scraper drive device for an automatic natural grass football field laying device according to this application embodiment is as follows: When laying is required, the turf roller is first placed on the support roller 22 of the roller seat 2 to ensure that the turf roller can rotate freely. According to the width of the turf, the motor 62 is started, and the motor 62 drives the double-headed screw 61 to rotate, which drives the two sets of limit stops 4 to move through the threaded sleeve 421. The distance between the two sets of limit stops 4 is adjusted to adapt to the width of the turf. The moving vehicle 1 is started and slowly moved forward. The turf roller rotates on the support roller 22, and the turf gradually unfolds. According to the laying situation of the turf, the scraper assembly 3 is driven to flip by controlling the extension and retraction of the electric cylinder 10, and the angle between the scraper assembly 3 and the ground is adjusted so that the scraper can better lay the turf flat on the ground. During the laying process, the limit stops 4 limit the turf on both sides to prevent the turf from shifting to the sides.

[0038] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
